Abstract

The invention relates to the production of polymeric materials, in particular rubber, and can be used in preparatory workshops of tire factories and rubber products factories. The purpose of the invention is to improve the performance of the device. For this purpose, in the heat treatment chamber 1, a device for flattening the loops is mounted under the mechanism 6, 7 for forming loops. The device is made in the form of a reference 8 and clamping 9 movable screens. The screen 8 is interleaved by the pneumatic cylinder 11, and the screen 9 by the pneumatic cylinder 10. After the formation of 3 loops on the rod 3 by means of the mechanism 6, 7 to form loops, the screens 8 and 9 are installed parallel to the end of the loop 4. The screen 9 rotates on the levers 12 and presses the lower end of the loop 4 to the screen 8. In this case, the loop 4 is flattened, but there is a small gap between its branches to prevent them from sticking together. 2 Il. (O (Ln with ISD 00 ND ig.1

Description

The invention relates to the production of polymeric materials, in particular rubber, and can be used in preparatory workshops of tire factories and rubber products factories.

The purpose of the invention is to increase the productivity of the device by increasing the capacity of the heat treatment chamber.

FIG. Figure 1 shows the proposed Q-looping of loops, namely, the reference frame at the time of compression of the loop of material (H1 strands do not mix); in fig. 2 - the same, at the time of mixing rods.

The device for heat treatment of the tape polymer material contains the parana o lowered to the lowest position on the bottom of the heat treatment chamber 1, the pressure screen 9 is retracted to the extreme left position to the vertical branches of the chains 2. After looping under the action

Simultaneously installed in chamber 1 for 5 pneumatic cylinders 10 and II, reheating is carried out for endless driving marking of the supporting 8 and clamping 9 of the screen 2 (drive not shown), on which the shafts are new. The support screen 8, lifting the bars 3 over the nano-clamped, is intended to inspire the loops 4 of the processed material (Fig. 1). In front of the camera 1 for heat treatment, a feed conveyor 5 is installed. A mechanism is formed above the rods 3 in the front upper part of the chamber 1 for heat treatment. The device consists of a roller 6, installed by a guide 14, comes in from one side of the loop, the pressure screen 9 turning 4Q on the levers 12, presses the lower end of the loop to the support screen so that there is a small gap between the branches of the tape of polymer material 15, eliminating contact of the branches of the material (Fig. 1). After the flattening of the loop, the screens 8 and 9 are under the action above the rods 3, and the copiers 7, by the interaction of the pneumatic cylinders 10 and 11, discharging the t-acting with the rods 3. In front to the initial position (Fig. 2).

A device for flattening the loops of the tape material, made in the form of a support 8 and a pressure screen 9 with means for moving them, is mounted under the mechanism of looping. The latter are made respectively in the form of cylinders 10 and 11, which are hinged on chamber 1 for heat treatment. The clamping screen 9 is fixed at the rising side of the chain 2. The hinged levers 12 are mounted. Next, the next loop of the processed polymer material 15 is formed. Screens 8 and 9 again perform the described cycle of movements. Thus, the flattening of 4 all the cooled polymeric material 15 hinged on the rods 3 occurs. The rods 3 are shifted to the non-working position under the force of gravity on the vertine.

The device works as follows.
