Description

one

The invention relates to the equipment of rubber and tire factories, in particular, to devices for uniform feeding of the calender with rubber mixture in the form of pieces of a syringe cable along the entire length of the gap between the calender rolls.

There are known devices for feeding a calender with a rubber mixture, a conveyor and a rubber mixture conveyor and a riopole for introducing the rubber mixture into the gap between the rolls of the calender, made in the form of a hinged apron on the anvil support, laying it down, connected with the pressure regulator. in the hydraulic system of rotation of circular knives to a predetermined cutting width of the rubber compound tape, fed by a conveyor to the center of the gap between the calender rolls. However, such a device does not evenly distribute, control and maintain an optimal mix supply over the entire length of the working gap between the rolls of the calender.

In the proposed device, a device for introducing a rubber mixture is made in the form of a work table horizontally mounted along the gap between the rollers, along which a slide from the pneumatic conveyor mounted across the desktop and at the level of the rubber mixture is located in the guides between the rollers from the feed conveyor surface. In addition, the carriage pusher is rigidly connected by means of spring-loaded rods with a carrier bar, which comes with a screen mounted on the carriage in the slots of non-contact limit switches that control the carriage pnavmo-cylinder.

photo relay and electromagnetic valve. This ensures uniform distribution, control, and maintenance of the optimum mixture over the entire working length of the gap between the rolls of the calender by automatically replenishing the rubber mixture with individual portions of dead-sprung rope.

FIG. 1 shows a device with a pusher for feeding a rubber mixture in the form of pieces of a syringe cable, general view; in fig.

2 - the position of the pusher with a lack of rubber mixture between the rollers; in fig. 3 - the same, with a normal supply of the mixture.

The device for feeding the calender with a rubber mixture contains a rubber feed.

a mixture of traisportar 1 and a device for introducing the rubber mixture into the gap between the rollers 2 of the calender. A device for the introduction of a rubber mixture is made in the form of a horizontally mounted on the gap between

rollers 2 of the calender of the working table 3, along which in the guides 4 there is located a carriage 6 movable from the lenemo-cylinder 5 with a pusher 7 for feeding the mixture in the form of segments 8 into the gap between the rollers 2 from the feeding transparter 1 mounted transversely-5 and 3 at the level of its surface. The pusher 7 of the carriage 6 is rigidly connected to the movable holes 9. The carriage 6. The spring-loaded 10 springs II with the bar 12, the carrying screen 13, 10 entering with the screen 14 fixed on the carriage 14 in the slot of the contactless limit switches 15, 16 and 17. The latter are mounted on guides 4 carriages and controlling the pneumatic cylinder 5 of the carriage 6 by means of a photo-15 relay, an illuminator 18 and a light-spreader 19 of which are installed on both the side of the transport Teipa 1 and the electromagnetic valve 20. A piece moved by a conveyor. 8 of the syringe harness of the mixture, and tilting to the 20 pusher 7, blocks the light beam of the illuminator 18. As a result, the light receiver 19 sends a signal to turn on the electromagnetic valve 20, which lets air into the cavity of the pneumatic cylinder 5. The rod 25 of the cylinder 5 pushes the carriage 6, moving it along the shaft. 4 to rolls 2 calenders. Ori the leftmost position of the carriage 6, the screens 13 and 14 enter into the slots of the switches 17 and 16. At the same time, the switch 16 gives a sipnal to turn off the valve 20, and the carriage returns to its original position. At the same time, the screen 14 enters into the program of the contactless switch 15, which prepares the electrical circuit of the device for the execution of the next / cycle. The switch 17 with the screen 13 inserted into its slot fixes the lack of a rubber mixture in the gap between the rolls of the calender. The next cycle of operation of the device is produced.

;. , Tzshvstvstv. When creating a normal mix between the rollers 2 of the calender, the pusher 7 moves to the right (Fig. 3), compresses the spring 10 and moves the screen 13. As a result, the screen 13 does not fit into the slot of the switch 17, which sends a signal to turn off the solenoid valve 20-G pneumatic cylinder 5 does not work, a section of the mixture tow passes the pusher 7 and returns to the syringe. The subject of the invention d. A device for feeding the calender with a rubber mixture, containing a rubber feed conveyor and a device for introducing the rubber mixture into the gap between the calender rolls, so that, in order to ensure uniform distribution, control and maintain an optimum supply of the mixture over the entire working length of the gap between rolls of the calender by automatically replenishing the rubber mixture with individual portions — segments of the syringe cable; the device for introducing the rubber mixture is made in the form of a horizontally installed lennogo across the gap between the rolls of the working table, along which a guide located on the movable carriage with pusher pnevmo.tsilindra rubber composition into the gap with the feed conveyor rolls mounted transversely Rabo; table and which at its surface level. 2. The device according to claim 1, characterized in that the carriage pusher is rigidly connected by means of spring-loaded rods with a bar supporting the screen, which comes with a screen mounted on the carriage in the slots of contactless limit switches that control the carriage pneumatic cylinder with a photo relay and an electromagnetic vents
