Abstract

This invention relates to the processing of polymeric materials. The purpose of the additional invention is to facilitate the servicing of the device by automating the process of charging the cooled ribbon to the selection conveyor. For this purpose, a rocker arm 12 is mounted on the lid 2 of the cooling chamber 1. A spring-loaded C-shaped head 13 with a lifting rod 14 is connected to one of its ends. The C-shaped head 13 covers an annular support in cross-section. A drive 20 is coupled to the other end of the rocker arm 12. When the device is operating, the head makes a swinging movement in a vertical plane and with the help of a rod 14 removes the cooled tape 24 from the ring support and transfers it to the selection conveyor 6. 3 sludge.

The invention relates to the processing of polymeric materials and is an improvement of the invention according to the author. St. No. 1353611.

The purpose of the invention is to facilitate the maintenance of the device by automating the process of refilling the cooled tape to the selection conveyor.

FIG. 1 shows a device for cooling a rubber band; in FIG. 2 — a yoke with a staple; in fig. 3 is a section A-A in FIG. 2

The device comprises a cooling chamber with a lid 2, mounted in the chamber by means of a central vertical axis 3, a driving transport body 4 for moving loops through the chamber of the cooled ribbon, feeding 5 and selecting 6 conveyors. The conveying body 4 is made in the form of an annular tubular support, between the feeding conveyor 5 and the conveying body 4 a funnel 7 is installed with a drive 8 for looping the tape onto the conveying body 4. A selection conveyor 6 is installed above the cover 2 and provided with a driving roller 9.

Inside the chamber 1, on the arm 10 of the cover 2, an arm 11 is pivotally mounted on the arm 12, on one of whose arms the head 13, encompassing the cross-section of the ring support, is pivotally mounted. A lifting rod 14 is secured on the C-shaped head 13, which enters the gap between the branches of the initial loop of the cooled tape. The head 13 rests with its upper end on the bracket 15 fixed on the casing 12. The spring 16 with the guide rod 17 is placed between the bracket 15 and the head. To ensure rotation of the head 13 relative to the yokes 12, when interacting with the ring support at the free end of the head bevels 18 and 19. The second arm of the rocker arm 12 is connected with a drive 20 of a reciprocating movement, mounted over the chamber 1 and controlled by a limit switch (not shown).

The chamber has irrigation sections 21 and an airflow 22 (not shown). A tray 23 mounted adjacent to the chamber 1 is intended for receiving the cooled tape.

The device works as follows.

Preheated rubber tape 24 is removed from the rollers (not shown) and fed to

conveyor 5. From the latter, the tape 24 is fed to the funnel 7, which, under the action of the actuator 8, makes a swinging motion. At the same time, the rotation of the annular support begins with the axis 3. The ribbon 24 is hung by the hopper 7 on the annular support by loops displaced one relative to the other along the perimeter of the support. When sequentially moving through the irrigation section 21 and the blowing section 22, the tape is cooled and drained. When approaching the qualifying

to the conveyor b the initial loop runs over

rod 14 and a limit switch

a signal is given to turn on the drive 20.

Driven 20 one shoulder rocker arm 12

is lowered, and the second shoulder with the head 13 rises together with the rod 14 and the first loop of the cooled ribbon 24. The head of the upper bevel 18 rests on the ring support and, turning, moves away from the latter, which allows the rod 14 to move

up and remove the loop from the support. When the head 13 with the rod 14 rises above the support, under the action of the spring 16 it turns to its original position.

In the extreme upper position of the rocker arm 12, the rod 14 with the loop rests on the drive roller 9, by means of which the tape is removed from the rod 14 and captured by a conveyor belt. After that, the drive 20 returns the beam 12 to its original position.

In this case, the head interacts with the support by the lower bevel 19, which allows the pin 14 to be withdrawn and the head to bend around the support unhindered. The spring 16 returns the head with the rod to its original position.

Subsequent loops are picked up from the support automatically by taking out the cooled belt by conveyor 6.
