    Arrangements for the treatment of a moving material web by means of an air flow are used for example in the packaging industry for the drying of packing material in web- shape. In this process the web passes through a chamber provided with inlet and outlet for the air, and at high air velocities the web is affected in an undesirable manner so that an uneven, unstable movement is imparted to it. In the arrangement in accordance with the invention this is avoided by means of a baffle plate (9) placed at an angle in relation to the web between the web (4) and the outlet (8) which causes a partial vacuum which balances the web and gives it a calm and steady movement through the chamber (1).

    专利说明:

    The invention relates to devices for treating a floating material web, which comprise a chamber having an inlet and a code for a material web and an inlet and an outlet for passing a gas stream.
    The aim of the invention is to ensure stable and uniform movement of the material.
    FIG. 1 shows the proposed device, side view; in fig. 2 - the same, increased.
    The device comprises an elongated chamber 1 made of stainless steel with an inlet 2 and an outlet 3 with openings located on opposite sides of this chamber. The web of packaging material 4 moves almost along a straight line from the inlet 2 to the outlet 3 of the opening in the longitudinal direction of the chamber 1, passing by the processing elements located in this chamber.
    On the upper side of the chamber there is an inlet 5 for introducing gas, for example, sterilizing hot air, which can be adapted to wash the web through a nozzle 6 (air knife) directed at an angle to the web of material 4. The guide wall 7, passage The material extending parallel to the web 4 constitutes a continuation of one wall of the nozzle 6 and is intended to direct the flow of air along the material web, which is indicated by the arrows. On the underside of the chamber there is an outlet 8 for gas which is shielded from the web of material 4 by means of a reflection plate 9 located inside the chamber. The baffle plate 9 is positioned in such a way between the exit points.
    a hole 8 and a web of material 4 at some distance above the wall 10 surrounding the outlet orifice, that gas that flows between the side edges of the web of material 4
    40 for which camera 1 is used. For this purpose, a so-called air knife is used, which is a narrow strong jet of hot sterile air that is introduced under
    45 acute angle relative to the surface of the fabric material. High-velocity air cleans the surface on which a relatively thin layer of sterilized and adjacent side walls remains (not a Q-agent due to rapid evaporation; technological chamber 1 may be peroxide, after which air will mix to reach the outlet opening 8 with vaporized sterilizing through the gaps 11, 12 for the release of gas, the agent is taken out of the chamber through the outlets formed between the front and the outlet opening 8 (the direction of the moving rear edge respectively of the reflector-55 is indicated by the arrow and in Fig. 1, the tel plate 9 and the wall 10. The wall and 2). ka 10 simultaneously serves as the bottom of the chamber 1. The placement of the reflective plastic guide wall 7, located 9 of the tire relative to the outlet ot behind the nozzle 6, provides prote

    Versti 8 and blade 4 is shown in FIG. 2
    FIG. 2, it is possible to see how the reflection plate 9 is positioned relative to the bottom wall 10 of the chamber and the web of material 4. Letters a and b indicate the width of two gaps 11 and 12 for the release of gas. The values of a and 4 are chosen equal to 5 and 2.5 mm, respectively, which ensures the inclination of the reflective plate 9 relative to the web of material 4 from 1 to 3, depending on the length of the reflective plate. The length of the reflective plate depends on the amount of air passing, and is approximately 200 mm.
    After installing the proposed device in the working position in the packaging machine, the web of packaging material 4 during its processing moves from the inlet 2 to the outlet 3 through chamber 1. On the web of material 4, which uses laminated material containing outer layers of thermoplastic, by introducing it into chamber 1, an external coating of bactericidal substance is applied, for example, hydrogen peroxide. The application of the bactericidal agent is carried out by known methods, for example, by spraying or passing the material through a bath with
    5 bactericidal agent in it. After the bactericidal agent has completed its functional value, it is removed from the surface of the web of material being processed,
    0 for which camera 1 is used. For this purpose, a so-called air knife is used, which is a narrow strong jet of hot sterile air, which is introduced under
    which hot air from the nozzle 6 is at a predetermined distance, in contact with the web of material, which reliably ensures heating and evaporation of residues of the sterilizing agent. However, the presence of a strong air flow is due to the occurrence of the so-called Coanda effect, due to the formation of a partial vacuum between the guide wall 7 and the web of material 4, due to which the web of material A tends to rise and approach the guide wall 7. At the same time The material 4 is affected by the flow of air passing through the outlet 8, which in known constructions caused the movement of the material web with vibration and under adverse conditions could lead to damage to the web of material that was in contact with some parts of the walls of chamber 1 or adjacent elements to it. To prevent this, and to ensure the conditions for floating the web of material 4 through chamber 1, without touching any part of it, a reflective plate 9 is used, by means of which air passing in the space of the drying mode. For airflow with a flow of 100 o
    The slope of the reflective plates) 9, the length and width (respectively, a and in Fig. 2) of the gaps are adapted to the specific air flow, which is specified from the conditions
    between the longitudinal edges of the web of material 4 and the side walls of the chamber 1 from the upper side of the web of material to its lower side.
    and with a temperature of 130 C, the width of the air gaps should be respectively 5 and 2.5 mm. In this case, it is directed in such a way that the pain-35 ° of reflective gshastina should
    be 1-3. In all cases, the gap 11 (q) must be wider than the gap 12 (b), which is necessary for the proper functioning of the devices a. This means that the distance between the baffle plate 9 and the web of material 4 should increase in the direction of movement of the web of material 4. To provide the required air flow, the wall 10, which usually serves as the bottom wall of chamber 1, should be parallel to the direction of movement of the web of material 4. .
    Its part flows between the baffle plate 9 and the material web 4, the passage through the guide gap 11 under the baffle plate 9 and further to the exit through the outlet hole 40. A smaller part of the air flow flows to the exit hole 8 through the gap 12. If there is the reflection plate 9 achieves an increase in the speed of the air flow 45 as it passes between the reflection plate 9 and the web of material 4, which leads to the formation of a partial vacuum, which due to the Coanda effect counteracts 50 hours ichnomu vacuum, obrazuyuschemus on the opposite side of the web material. As a result,
    be 1-3. In all cases, the gap 11 (q) must be wider than the gap 12 (b), which is necessary for the proper functioning of the devices a. This means that the distance between the baffle plate 9 and the web of material 4 should increase in the direction of movement of the web of material 4. To provide the required air flow, the wall 10, which usually serves as the bottom wall of chamber 1, should be parallel to the direction of movement of the web of material 4. .

    Noah 9. The device becomes self-balancing, because when approaching the web of material 4 on
    too close to the baffle plate 9, the free space for air decreases, which causes most of the air to flow through the gap 12 past the baffle plate 9 and reduces the air flow between the baffle plate 9 and the material web 4. In turn, this leads to a partial decrease in pressure, whereby the web of material again departs from the baffle plate 9. Similarly, the increase in the distance between the web of material 4 and the baffle plate 9 is connected With an increase in the air flow flowing along the baffle plate 9 and through the gap 11, which leads to the formation of a partial vacuum and the return of the material web to a closer distance from the baffle plate 9.
