    The invention relates to the industrial construction materials, in particular to the equipment of glass fiber factories.
    The closest to the invention according to the technical essence and the achieved result is a device for producing fiberglass, including a perforated plate with a flat bottom surface and a mechanism for supplying cooling air Cll.
    With this method, before starting work, or when all the fibers break down during operation, the molten glass adheres to the bottom surface of the perforated plate, drains and drains in the form of one or more streams. Under such conditions, separation is necessary (to obtain - NIN glass fibers flowing through all the holes separately, which is done manually as follows: the temperature of the perforated plate decreases by 20-60 ° C below the temperature at which it is produced
    from the day. The air is blown through the nozzles, located at the bottom of the perforated plate, in an amount about 1/3 less than during normal operation. The mass of molten glass, located at the bottom of the perforated plate, is captured, for example, by forceps, which are gradually pulled downwards with the trapped mass of molten glass. The separation starts from the rear end of the openings on the side of the air nozzles and as it is pulled back, the separation advances.

    When the separation reaches the front of the perforated plate, the flow rate of the glass through the holes increases and the glass cones tend to coalesce again, and therefore the amount of air should gradually increase. In this case, the perforated plate is subjected to increasing cooling. Therefore, the temperature gradually rises, so that the flow rate of the glass cannot be reduced again. When separation occurs in all openings, the temperature and amount of air supplied will increase to values consistent with normal operation. During this procedure, manual defrosting is performed at a speed of 3-70 cm / min, while at the same time the amount of air and the temperature are controlled. For normal separation, the following conditions must be met: the perforated plate must not be moistened with molten glass in order to impede the wetting, it is necessary to lower the temperature. In addition, a sufficient amount of glass must be supplied through the holes. When the glass is cooled and its speed is extremely small, the heat capacity of the glass decreases so that further cooling of the glass occurs. Consequently, the flow of glass ceases and the fibers are destroyed 9 so that the separation-1e becomes unmilled. Therefore, if the air cooling increases, the temperature of the perforated plate must increase, and the air temperature and temperature must be adjusted during the separation; much attention. The step of manually drawing the glass requires careful attention and patience for an hour, then a breakdown occurs. If the stage of the 11-Ian system is broken, in most cases the separation should start from the very beginning. A failure in the drawing stage occurs under conditions when the glass of the glass is immediately after the beginning of the drawing stage, a certain amount of glass flows through the holes, so that the glass held by the worker increases. When the worker releases the glass, it flows at a high speed, which results in glass fiber. Therefore, the worker should rather maintain the glass mass than t her, and should apply the required pulling force to the glass. However, in the case of a perforated plate with a large number of holes, for example 3000-4000, glass, through these holes, has significant weight, so moving the glass from one hand to the other and a very small movement of the worker’s hand creates stress in the glass, where thermal stress exists, therefore part 04 or the entire glass is destroyed. When the glass breaks, the drag force decreases, the flow speed also decreases, and the perforated plate is supercooled and therefore separation cannot continue, except when the drag force disappears because the glass becomes entangled in the air nozzles and the calibrator. ; when the increase in air supply occurs too quickly during operation, which also leads to hypothermia. When moving glass from one hand to another, a worker creates a force that acts only horizontally, not down. In this case, the split glass breaks immediately. These failures are caused by inattention, fatigue and inexperience of the worker. During work, the worker must maintain the force applied by him in order to pull the glass very slowly and attentively at a constant speed in a given direction under conditions in which it is exposed to radiated heat and hot air reflected by a perforated plate. In addition, the worker cannot release the glass, no matter how tired it is. Diversity is most common when it changes its statutory hand, since the direction of stretching changes slightly. Difficult and hard work is to achieve complete separation in such conditions. The purpose of the invention is to increase efficiency. The goal is achieved by the fact that a device for producing fiberglass, including a perforated plate with a flat bottom surface and a cooling air supply mechanism, is equipped with a mechanism for drawing glass cones, made in the form of a fixed shaft with a carriage mounted for movement along the shaft, and mounted on the carriage mechanism for capturing glass melt.

The device comprises a furnace I filled with molten glass 2 with a perforated plate 3 having a flat bottom surface and attached to the bottom of the furnace 1 having a large number of, for example 4000-6000, number of straight holes that are apart from a distance of less than 3 mm. The distance between the holes is such that the adjacent cones formed on the lower surface of the perforated plate with molten glass flowing from separate holes usually merge, but air jets are blown onto the plate through nozzles, each of which contains a tube and which are located below the furnace 1, whereby the cones of the molten glass are cooled and separated from each other. Each cone is continuously drawn into the fiber 4 and then enters the calibrating device 5 with a lubricant or coating agent, the fibers 4 70t prohrd through the collecting roller 6 to form one strand 7 or more. Strand 7 passes a transverse guide 8 and extends onto the spindle 9 at a speed of 500-2000 m / min to form the package 10. The hose 11 is connected to the nozzles 12 and low pressure air is supplied through it from a compressor or blower. A plurality of tubes formed by nozzles 12 are fixed in one row on a stand 13, which in turn is mounted on a device for adjusting position 14, vertically moving along a stand 14 installed vertically on the floor in the spin shop. In this way, the nozzles 12 can be adjusted up and down, right and left, forward and backward. The glass cones pull-out mechanism is made in the form of a fixed shaft 15 mounted obliquely relative to the furnace outside the area immediately below the furnace 1, the trapping mechanism of the glass melt 16 containing two gripping elements made of a heat-resistant alloy and forming toothed blades at the front ends, and This mechanism for grabbing the glass melt is mounted on a sliding carriage 17 moving from up and down along the non-driven shaft 15. On one side of the carriage 17 there is a reversing motor 18 and a gearbox 19, which is directly connected to reversing motors 18. Bevel gear 20 is attached to the output shaft 21 of the gearbox 19 and the bevel gear 22, which engages the bevel gear 20, is fixed to the worm shaft 23, which is supported by two bearings 24 in the carriage 17. Worm 25 on the worm shaft 23, hooks on the worm gear 26, mounted on the shaft 27, which is supported by two bearings 28 in the carriage 17, which is perpendicular to the worm shaft 23 (see fig 4J. The carriage 17 has a cylindrical lever 29, an imeck for drilling, in which there is a fixed shaft 15, and a sliding along a fixed bore 15 through a metal sleeve 30 fixed on the inner surface of the cylindrical lever 29, which rotation is prevented by a key 31 inserted into the fixed shaft 15. The cylindrical gear 32 is mounted on the shaft 27 and engages the rail 33 on the fixed shaft 15 through a slot in the cylindrical lever 29. With this arrangement, the rotation of the reversing motor 18 is transmitted to the cylindrical gear 32 through re The vector 19, the gears 20 and 22, the worm to 25 and the worm gear 26. As a result of the rotation of the cylinder gear 1 32 in engagement with the rail 33, the carriage 17 moves up and down along the fixed shaft 15. Each of the spinner 16 is connected with using bolts 34 with a finger 35, which refers to the finger of a solenoid, an electromagnetic, automatically activated switch 36 and, when voltage is applied to switch 36, the glass-gripping mechanism closes. As shown in FIG. 5, the electromagnetic automatically activated switch 36 is swiveled to the right on the support plate 37, which is placed on the electromagnet 38, fastened by a bolt 39 on the front frame of the rotating lever 40 extending from the carriage 17, and which is securely held on the electromagnet 38 when the latter is turned on. When turned off, turn on the power switch. 38, an electromagnetic, automatically activated switch 36 and, consequently, a gripping mechanism of the glass 16 can be removed from the lever 40. The latter is bolted on. 41 to the upper end of the gear 42, which rotates on the bearings 43 around the shaft 44 attached to the base 45 of the carriage 17. The gear 42 engages the gear 46 mounted on the output shaft 47 of the gearbox 48 directly connected to the engine 49, which is fixed to the bottom surface the base 45 of the carriage 17. The engine 49 is driven by the lever 40 ,, turns in the directions indicated by the double arrow in FIG. 4, the desired position. The fixed shaft 15 (Fig. 6 and 7) is flange 50, which is integral with its lower ring and connected by bolts 51 to flange 52, formed on the upper end of the bracket 53 fixed by a key on the shaft 54 of the worm gear. Shaft 54 a worm gear is supported by two bearings 55 in supporting columns 56 protruding upward from a base 57 attached to the spinning chain floor; a worm gear 58 is attached to one end of the shaft 54. On the base 57 a frame is mounted, 59 on one side of the supporting columns 56 and shaft 60 worms, on which The ts worm to 61 engages with a worm wheel 58 and extends vertically and is supported by bearings 62 in frame 59. When the upper end of the worm shaft 60 is turned with a wrench, the stationary shaft 15 swings in the directions indicated by arrows, depending on the direction of rotation of the worm As a result, the angle of inclination of the stationary shaft 15 can be changed. In this case, the worm c has the property of self-holding, so that without rotation of the worm shaft 60, the stationary shaft 15 is maintained at a given angle of inclination. The device works as follows. The fixed shaft I5 is held at a certain angle of inclination with the aid of the screw shaft 60, during the spinning operation, the carriage 17 is located on the fixed shaft 15 below, as shown in FIG. 1, while the rotating arm 40 is located in such an angular position, in which the gripping mechanism of the glass mass 16 does not interact with the flow of fibers coming out of the holes. The carriage raising the carriage 18 is turned on, so that the carriage 17 moves up along the fixed shaft 15 and at the same time the motor 49 is turned on, turning the lever 40 to deliver the grab mechanism 16 to the center of the furnace. When the glass trapping mechanism reaches a position in which it can grip the mass end of the molten glass hanging from the perforated plate in the form of a large cone (see Fig. 8), the limit switch (not shown, acts so that the carriage 17 stops and simultaneously the electromagnetic, an automatically activated switch 36, so that the mass of molten glass is captured, as shown in Fig. 9. Then, the lifting carriage reversing motor 18 starts to rotate in the opposite direction, so then the carriage 17 moves downward at a constant speed, causing the captured molten glass to be pulled back (Fig. 10). As soon as the carriage starts moving downward, the amount and pressure of air leaving the nozzles 12 and the temperature of the perforated plate is adjusted so that the separation of the molten glass from the fiber begins. eleven). When it is seen that the fibers are completely separated, the electromagnetic switch 36 is turned off and the piece glass adhering to the front ends of the fibers is removed and the grab-trapping mechanism 16 is returned to its original position. The spinning of the divided loops begins again. Thus, in accordance with the invention, the separation and extrusion of molten glass are fully mechanized and can be easily automated with a POM of an appropriate control system. Split disruptions can be eliminated and labor savings can be achieved. Claim 1.
