Description

one

The invention relates to equipment of rubber industry plants, in particular to devices for processing materials based on rubber in a roll machine.

The aim of the invention is to facilitate the maintenance of the device.

The drawing shows the device a General view.

The device comprises reciprocatingly mounted relative to the roll 1 of the roll machine a knife 2 for separating a strip of material from the roll surface. The knife 2 is mounted on a pivot arm 3, the axis 4 of which is mounted on the frame 5, the lever 3 is pivotally connected with the means for moving the knife relative to the roll 1, for example with a pneumatic cylinder 6 fixed on the frame 5.

Under the roller 1, in the zone of separation from its surface of the tape of material, a device is mounted for rolling 1 a roll of material to be taken out of the roll, including a support: ivak) —justing roller 7 and driving sealing rollers 8,

There is also a pusher 9 for dumping a roll of material that is hinged

connected by means of levers 10 and P with a pneumatic cylinder 6, and the lever 10 is connected with lever 3 by means of an axis 12.

5 The device operates as follows.

The blade 2, the tape 2, is pressed against the rotating roller 1

13 material is separated from the surface of the roll 1 and enters the rotik

Sealing devices, where the roll 14 rolls around, skirting the rollers 7 and 8, upon reaching the roll

The required diameter of the pneumatic cylinder 15 15 is switched and the knife 2 is retracted

from the surface of the roll. In this case, the separation of the tape from the latter is stopped and it is cut off under the action of the force of the seaming device,

20 Simultaneously, when the rod of the pneumatic cylinder 6 moves through the arms O and 11, the pusher presses the roll and pushes the latter out of the rollers of the seaming device. After switching the pneumatic cylinder 6 to the initial position, the knife 2 is pressed against the roller 1 and the separation of the tape from its surface is resumed. The pusher 9 returns to its original position and winds up the new roll 14.

Claims (1)

DEVICE FOR SELECTING POLYMER MATERIAL TAPES FROM THE ROLLER ROLLER MACHINE, comprising a knife for separating the material tape from the surface of the roller and a device for rolling material from the roller to be rolled relative to the roller, characterized in that, in order to facilitate maintenance of the device, the seaming device is equipped with a rotary pusher for dumping a roll of material pivotally connected by means of levers with means for moving the knife, and the seaming device is installed but under the roller in the zone- separating from his belt material.
