    FLOOR TILES PRODUCTION DEVICE
    BACKGROUND OF THE INVENTION
    1. Field of the Invention
    The present invention relates to a floor tile making device, and more particularly, to a floor tile making device installed on a floor to reduce the energy and labor cost necessary to produce a floor tile that gives the floor a specific color, pattern and texture can, and to increase productivity.
    2. Description of the Prior Art
    In general, floor coverings such as floor paper or tiles are built on a floor of a building, and the main material of the floor covering such as floor paper or tiles is vinyl chloride, which is light, flexible and excellent in terms of damping and sound insulation properties.
    The floor covering, which has vinyl chloride as a main material, comprises a substrate layer having a PVC plastic as a main material, a printing layer connected to an upper end of the substrate layer and a layer of transparent film connected to an upper end of the printing layer.
    BE2017 / 5721
    Furthermore, if necessary, a coating for improving an anti-wear property and an anti-scratch property can then be provided with an upper end of the
    Layer of transparent film can be connected.
    The substrate layer has a PVC plastic, which is one of its main materials, a filler and a plasticizer, and the layer of transparent film can only be made of a PVC plastic without using a filler. The floor covering with the above configuration is used alone in a floor finishing process, or is used while attached to various types of adhesives or adhesives.
    However, a flexural strength of the floor covering having the above structure may deteriorate massively due to a difference between the contraction coefficient of the transparent film layer and that of the substrate layer, and thereby during or after one
    Deployment process to one
    Stepping out, which roughen a seam, or due to heat or moisture to one
    Deformation or distortion.
    To the
    Solving tasks becomes one
    Leveling layer at a lower end of the
    PVC substrate layer in one
    Manufacturing process of
    Flooring trained. FIG.
    is a sectional view
    BE2017 / 5721 of a conventional flooring with an improved
    Flexural strength.
    As in Fig. 1 illustrates is, points the conventional Flooring with one improved flexural strength a substrate layer 10 as on main material one PVC KunstStoff having, a Print layer 20 and a layer 30 out transparent Movie the line after with one top side the substrate layer 10 are connected, and a
    Compensating layer 40, which is connected to a lower end of the substrate layer 10.
    Furthermore, the substrate layer 10 has an upper PVC layer 11, a lower PVC layer 13 and a nonwoven layer 12, which is connected between the upper PVC layer 11 and the lower PVC layer 13.
    In order to produce the conventional flooring structured as described above with an improved flexural strength, the printing layer 20 and the transparent film layer 30 must first be prepared and the substrate layer 10 and the leveling layer 40 must be produced separately.
    Furthermore, in order to manufacture the substrate layer 10, a nonwoven fabric must be inserted between the upper PVC layer 11 and the lower PVC layer 13 and then hot pressed after the upper PVC layer 11 and the lower PVC layer 13 have been formed separately. Then there is a cutting process
    BE2017 / 5721 the upper PVC layer 11 and the lower PVC layer 13 in certain sizes necessary to join the upper PVC layer 11 and the lower PVC layer 13 after the upper PVC layer 11 and the lower PVC layer 13 have been formed at a high temperature, and a process for cooling and aging the upper PVC layer 11 and the lower PVC layer 13 is necessary to prevent the upper PVC layer 11 and the lower PVC layer 13 from being deformed and distorted. After the cooling and aging processes, the upper PVC layer 11 and the lower PVC layer 13 are reheated and hot pressed to produce the substrate layer 10.
    In this way, in order to connect the substrate layer 10 and the compensation layer 40 after the production of the substrate layer 10, a process for reheating and hot pressing the substrate layer 10 and the compensation layer 40 must be carried out after a process for cooling and aging the substrate layer 10.
    As described above, in connection with the conventional flooring, there is an improved flexural strength - since the upper PVC layer 11, the lower PVC layer 13 and the compensating layer 40 have to be formed separately and heating, cooling, aging and reheating are in the formation and connection process must be repeated - consumption of energy such as fuel and
    BE2017 / 5721 electric storm due to reheating after the
    Cooling down big, labor costs rising and that
    Productivity drops.

    DETAILED DESCRIPTION OF THE EMBODIMENTS
    First has, referring to FIG. 5, a
    Floor tile of the present invention has a structure in which a lower sheet 1, a middle sheet 2, a printing sheet 3 with a pattern or a color, a
    transparent Slide 4 and an ultraviolet or UV coating (not illustrated) in turn
    are stacked.
    The thickness of the printing film, the
    BE2017 / 5721 transparent film and the UV coating are very thin and their contraction rates are high compared to the middle film. Accordingly, when the printing film, the transparent film and the UV coating are connected to the middle film, the floor tile may be bent or distorted by the difference between the contraction rates. In order to solve the tasks, the lower film is attached to a surface which is opposite the surface to which the printing film, the transparent film and the UV coating are attached, with respect to the middle film.
    Meanwhile, traditionally, to a
    To produce floor tiles with a total thickness of 3T, a total of three foils including a lower foil (0, 9T) and two middle foils (0, 9T) are used, the three foils are manufactured individually at a temperature of 180 degrees and at an ambient temperature of 20 degrees cooled, and the cooled lower film and the cooled middle
    Foils are rolled up into a roll and then preserved. Furthermore, in order to combine them closely, the lower film and the middle films must be on a
    Temperature of
    180
    Degrees to be reheated. For this
    The reason is with the conventional
    Manufacturing process the
    Heat losses that
    Electricity costs, labor costs and the
    Investment costs and the installation space for machines inflated and
    Consumption in relation to the production rate of the products
    BE2017 / 5721 high.
    The reason why the thickness of the lower film and the middle films is 0.9T is that productivity decreases because heat when the lower film or the middle films warm up is slow to enter the lower film or the middle films if one Have a thickness of 0.9T or more, and continuous production becomes impossible since the production is stopped, although the heat can quickly enter the inside of the lower film or the middle films if the lower film or the middle films is comparatively small Have a thickness of 0.9T or less.
    In particular, since a bottom film (0.9T) and four middle films (0.9T) must be produced to produce a 5T thick product, and a total of 7 films including a transparent film (0.3T) and need to be combined with a printing sheet (0.08 T), the manufacturing device becomes complex and the volume and installation space of the manufacturing device increase. Because, if exactly one middle film (3.6T) is made to reduce the volume and installation space of the manufacturing device, it takes a period of time to heat the middle film to a temperature of 180 degrees at which the middle film is combined at an ambient temperature can, increases rapidly, there is an increase in the productivity of the product
    BE2017 / 5721
    Restriction.
    Below is one
    Floor tile making apparatus according to the present
    Invention described in detail with reference to the accompanying drawings.
    As illustrated in FIGS. 2 to 6, the floor tile manufacturing apparatus according to the present invention includes a raw material feed unit 100, a lower foil feed unit 200, a middle foil feed unit 300, a combining unit (a lower preheat roller 410, an upper preheat roller 420, a main roller 430, a heater) 440, a first press roll 450, a first film feed unit 460, a second film feed unit 470 and a second press roll 480), a cooling unit 500, a UV coating unit 600, an aging unit 700, a cutting unit 800 and an automatic packaging unit 900. The components of the floor tile manufacturing apparatus according to the embodiment of the present invention are arranged in a straight line so that the floor tiles can be produced in large quantities while the material and raw material of the tiles can be fed endlessly.
    The raw material feed unit 100 stores the materials for a lower film 1 and a middle film 2 and feeds materials with different filler contents to the lower film feed unit 200 and the middle film feed unit 300.
    BE2017 / 5721
    The materials for forming the lower film 1 and the middle film 2 include polyvinyl chloride, a plasticizer (NEO-T), a filler and a plasticizer to make the formed product flexible. The filler improves physical properties such as strength and hardness, and in this version it uses calcium carbide (CaCo3). The filler is called hard coal or carbonized coal and can use various fillers other than calcium carbide.
    Meanwhile, calcium carbide contained in 100 parts by weight of a material supplied to the lower film supply unit 200 corresponds to 50 parts by weight or less, and calcium carbide contained in 100 parts by weight of a material supplied to the middle film supply unit 300 corresponds to 70 parts by weight or more.
    Although the contraction rate of calcium carbide, that is, the filler, decreases as the content of the filler increases, thereby simplifying prevention of the filler from deforming and maintaining the shape of the filler, the filler can break or tear, and costs increase if the The percentage by weight of the filler becomes too large. Since it is necessary to reduce the contraction rate and the deformation rate of the middle sheet 2, the filler is 70 parts by weight or more in the material of the middle one
    BE2017 / 5721
    Foil 2 of 100 parts by weight included. Accordingly, in order to compensate for the contraction and the deformation by the printing film 3 and the transparent film 4 and to break or tear the middle film
    To prevent 2 by adding flexibility, the lower film 1, which has 50 parts by weight of filler or less based on 100 parts by weight of the material, coupled to the middle film 2.
    The preferred composition ratio of the lower film 1 is given in Table 1.
    [Table 1]
    Togetherreduction polyvinylchlorid Bulkingf Weichmachere RATIOSis 36.3% By weight 47.3 wtchtsprozent 16, 4% By weight
    The preferred composition ratio of the lower film 2 is given in Table 2.
    [Table 2]
    Together polyviny Bulking Weichmac reduction lchlorid f here RATIOSis 17weight percent 71, 9% By weight 11.1% By weight
    The contraction rate of the product formed varies depending on the content of the filler (calcium carbide), and accordingly there is a difference between the
    BE2017 / 5721
    Contraction rate of the lower film 1 and that of the middle film 2.
    The present invention minimizes deformation and distortion of the floor tile by balancing the contraction rate by the printing film 3, the transparent film 4 and the UV coating, which are connected to a surface of the middle film 2, and the contraction rate by the lower film 1, which is connected to the other surface of the middle film 2.
    The lower film is generally also called a compensating film.
    Although not separately illustrated in the drawings, the material feed unit has
    100 one
    PVC tank for
    Storage of polyvinyl chloride and one
    Filler tank for storing the filler, and it has one
    PVC weighing tank, one
    Filling tank, one
    Plasticizer weighing tank and one
    Pigment weighing tank.
    The
    PVC weighing tank, the
    Filling material weighing tank, the
    Plasticizer weighing tank and the
    Pigment weighing tanks weigh the materials according to a certain ratio and deliver the weighed materials to a lower mixing tank 211 and an upper mixing tank 311.
    The lower film feed unit 200 forms the lower film 1 and feeds it. The lower film feed unit 200 has a lower film forming unit 210 for forming the lower one
    BE2017 / 5721
    Foil 1 and a lower foil storage unit 220 for
    Store the bottom slide 1 on.
    As illustrated in FIG. 3, the lower film forming unit 210 has a lower mixing tank 211, a lower extruder 212, first and second lower mixing rollers 214 and a lower calender roller 215, and the material passes through in sequence. The lower mixing tank 211 receives the material for forming the lower film 1 from the material supply unit 100 and mixes the material. The lower extruder 212 uses heat (170 to 180 degrees), pressure and friction to make a kind of dough from the materials mixed by the lower mixing tank 211. In the present embodiment, two lower extruders 212 are used to produce a thick lower film 1 in large quantities. The first lower mixing roller 213 has two heat rollers and compresses and kneads the material by passing the material kneaded by the lower extruder 212 between the two heat rollers (150 to 170 degrees). The second lower mixing roller 214 compresses and kneads the material that has passed through the first lower mixing roller 213 again at a temperature of 160 to 180 degrees and feeds the kneaded material to the lower calender roller 215. The lower calender roll 215 makes the mixed and kneaded material into a kind of disk with a certain thickness and a certain width by using the opening between the heating rolls, and it
    BE2017 / 5721 delivers the disc to the lower film storage unit 220. The lower calender roll 215 has a plurality of hot rolls, and a roll which passes the material first, from a plurality of rolls of the lower calender roll 215, heats the material to 140 to 160 degrees, and then the heat rollers heat the material to 160 to 180 degrees. In this way, the lower film 1, which has passed through the lower calender roll 215, is supplied to the lower film storage unit 220 by a cooling grid conveyor device which is 120 to 140 degrees.
    As illustrated in FIG. 4, the lower film storage unit 220 has a plurality of lower film holding rollers 221, a sensor (not illustrated) and a control unit (not illustrated), and the plurality of lower holding rollers 221 rise by an amount equal to that in the lower film storage unit 220 accommodated lower film 1 accommodated, according to a difference between a speed at which the lower film 1 is inserted from the lower film forming unit 210 into the lower film storage unit 220 and a speed at which the lower film 1 is fed out from the lower film storage unit 220 , Specifically, when the insertion speed of the lower film 1 is greater than the discharge speed of the lower film 1, the lower one stored in the lower film storage unit 220 becomes
    BE2017 / 5721
    Film 1 is first fed out while the plurality of lower film holding rollers 221 are lifted in order, and when the insertion speed of the lower film 1 is lower than the feeding speed of the lower film 1, the lower film 1 that is inserted becomes while the plurality of lower film holding rollers 221 can be lowered in order in the lower film storage unit 220. Furthermore, the lower film 1 stored in the lower film storage unit 220 is kept at a temperature of 110 to 130 degrees.
    Meanwhile, when the insertion speed of the lower film 1 is identical to the discharge speed of the lower film 1, a total amount of the lower film 1 stored in the lower film storage unit 220 remains unchanged and the lower film holding rollers 221 do not move.
    The bottom film is inside the bottom mentioned above
    Film storage unit
    220, and an upper cover part of the
    Film storage unit 220 can so raised be that the Inner the lower Film storage unit 220 open becomes.
    The middle film feed unit 300 receives this
    Material for forming the middle film 2 from the
    Material feed unit 100 and forms the middle film 2 and feeds it. The middle film feed unit 300

    220 are identical, and one of them is therefore omitted (see FIGS. 3 and 4).
    As illustrated in FIG. 5, the
    Combination unit a lower preheating roller 410, an upper
    Preheat roller 420, a main roller 430, a
    Heater 440 a first press roll 450, a first
    Foil feed unit 460, a second foil feed unit
    470 and a second press roller 480.
    The lower preheating roller 410 receives the lower foil from the lower foil feed unit 200 and supplies the lower foil 1 to the main roller 430 after heating the lower foil 1 to 170 to 190 degrees. Several heating means 411 are inside the lower preheating roller 410 along a peripheral surface of the Lower preheating roller 410 installed to heat the lower sheet 1 as it passes the lower preheating roller 410.
    BE2017 / 5721
    The upper preheating roller 420 receives the middle film 2 from the middle film feed unit 300 and, after the middle film 2 has been heated to 170 to 190 degrees, supplies the middle film 2 to the main roll 430. A plurality of heating means 421 are inside the upper preheating roll 420 along a circumferential surface the upper preheat roller 420 installed to heat the middle sheet 2 as it passes the upper preheat roller 420.
    As mentioned above, since the lower film 1 and the middle film 2 are supplied to the lower film preheat roller 410 and the upper preheat roller 420 while being kept at a high temperature after being mixed and formed by the lower film feed unit 200 and the middle film feed unit 300 have been heated, a temperature deviation from an initial temperature to a target temperature necessary to connect the lower film 1 and the middle film 2 when the lower film 1 and the middle film 2 are heated by the lower one Preheat roller 410 and top preheat roller 420 are not large to the target temperature. Accordingly, heating energy consumption can be reduced. Furthermore, since the middle film 2 is supplied while being kept at a high temperature, and although the heating time to also heat the inside of the middle film 2 to the target temperature may be extended if the thickness of the middle film 2 IT (1 mm)
    BE2017 / 5721 or more - the inside of the middle film 2 is kept at a temperature higher than that of the surface of the middle film 2 so that the middle film 2 can be quickly heated to the target temperature even if the thickness of the middle film 2 is large. Accordingly, the process can be carried out quickly, and the products can be manufactured in large quantities even if the thickness of the middle sheet 2 is large.
    The main roller 430 receives and connects the lower foil 1 and the middle foil 2. A plurality of heating means 431 are installed inside the main roller 430 along a circumferential surface of the main roller 430 at the temperature of the lower foil 1 and the middle foil 2 as they pass the main roller 430 to hold at 170 to 190 degrees.
    The aforementioned heating means 411, 421 and 431 can be heating wires which run through the rolls or heating liquids which flow through channels formed in the inside of the rolls.
    The heaters 440 are arranged above the main roller 430 to heat the lower film 1 and the middle film 2, which move along the main roller 430. That is, the heater 440 heats opposite surfaces of the lower film 1 and the middle film 2 that move along the main roller 430.
    The first press roller 450 presses the lower film 1
    BE2017 / 5721 and the middle film 2 in the direction of the main roller 430 in order to bind the lower film 1 and the middle film 2 together.
    The first film feed unit 460 guides the
    Main roller 430 a
    Printing film 3 with a color or a pattern
    The first film feed unit 460 may have two rollers such that the two rollers can be used alternately according to the situation.
    The second film feed unit
    Main roller 430 the transparent film
    470 leads the
    The second film feed unit 470 can also have two rollers in such a way that the two rollers can be used alternately according to the situation.
    The second press roller 480 presses the printing film 3 and the transparent film 4 in the direction of the main roll 430 in order to bind the printing film 3 and the transparent film 4 to a surface of the middle film 2.
    As illustrated in FIG. 6, the cooling unit 500 has a plurality of cooling rollers 510, on which the raw material of the tile runs, to which the lower film 1, the middle film 2, the printing film 3 and the transparent film 4 are sequentially bonded , A coolant is installed in each of the plurality of cooling rollers 510, and opposite surfaces of the raw material of the tile alternately touch the plurality
    Cooling rollers 510 to be cooled. The coolant
    BE2017 / 5721 can be cooling water caused by the inside of the
    Cooling rollers 510 formed channels flows. The
    Raw material of the tile is cooled by the cooling unit 500 to 20 to 40 degrees.
    The UV coating unit 600 forms a UV coating on a surface of the transparent film 4. Specifically, the UV coating unit 600 dries the surface of the transparent film 4 by UV by fusing a UV beam with the surface of the transparent film 4 to increase the strength of the surface of the transparent film 4 to increase the life of the transparent film 4 To prevent scratching.
    The aging unit hot water aging device cold water purification device
