Abstract

The invention relates to the manufacture of rubber products and can be used to remove scrap after vulcanization from reinforced rubber parts, such as glands. 2 The goal is to reduce refrigerant consumption and increase its efficiency. For this, it is provided with a casing made in the form of a semi-cylindrical tray. The tray is fixed under the flooring and covers the lower drive brush. The tray is removable and fixed to the support plates that are attached to the sides of the camera body. In operation, a product with a frozen edge is pushed by a conveyor between two brushes that remove the strip from two opposite planes of the product. The excess refrigerant through the transverse groove flows into the tray, where it gradually evaporates and, up the passage, maintains a constant temperature in the chamber. 1 hp f-ly, 1 ill.

WITH

The invention relates to the manufacture of rubber products and can be used to remove scrap after vulcanization from reinforced rubber parts, such as glands.

The purpose of the invention is to reduce refrigerant consumption and increase the efficiency of its use.

The drawing shows the device, the overall appearance.

The device consists of a frame 1 on which the housing 2 is fixed with an insulating outer surface. The housing is closed by a heat insulating cover 3, so that a cooling chamber 4 is formed between them. The housing 2 and the cover 3 are made trough-shaped. The cooling chamber is equipped with a conveyor 5, which consists of

two traction circuits connected by jumpers (not shown), and serves to transport the products 6. The open part of the conveyor between the side walls of the case forms the charging neck 7. The conveyor has a working branch 8 and a single branch 9. Inside the cooling chamber 4 a pair of cylindrical brushes is installed - the upper 10 and lower 11. Under the working branch of the conveyor there is a hard deck 12, while the upper brush 10 is located above the hard deck above the leading branch of the conveyor, and the lower brush 11 is located under the hard deck. At the place of installation of the brushes in a rigid flooring, a transverse groove 13 is made to pass the pile of the lower brush. The bottom brush is closed by a casing 14. and the casing

made removable in the form of a semi-cylindrical tray and attached to the supporting plates 15, mounted on the sides of the housing 2 of the camera 4 under the floor 12.

The casing closes the brush 11 from the bottom of the chamber 4. The drive of the chain conveyor 5 is from the drive mechanism 16 mounted on the frame 1. The drive mechanism of the brushes 17 is also mounted on the frame 1.

A coolant spray pipe 18, which is installed in front of the processing brushes, is introduced into the cooling chamber 4. An inclined chute 19 is attached to the body 2 at the place of unloading, which has holes 20 for emptying into the removable tray 21.

The device works as follows

The rubber-metal products 6 are loaded into the loading neck 7 from a bunker (not shown), the conveyor 5 is seized by bridges and moved by the flat side along the rigid floor 12. Under the action of the refrigerant supplied to the cooling chamber 4 by nozzles 18, the parts freeze through and become fragile. The frozen parts of the conveyor 5 are pushed between the rotating brushes 10 and 11, with the upper brush 10 peeling off the flap on the item b from the top, and the lower brush 11 processing the lower plane of the item. Excess liquid nitrogen through the transverse groove

13 flow into the tray 14. Gathered in the tray

The liquid nitrogen enters the vapor state and passes upward through the transverse groove. maintains a constant temperature in chamber 4, thereby achieving a reduction in the flow rate of liquid nitrogen.

After the product has been brushed, it is transported together with the deflated scrap by a conveyor to the place of unloading and along the inclined tray 19 it enters the finished product conveyor (not shown), while the blotter, waking up through the holes 20 in the tray 19, accumulates in a removable tray

which is periodically emptied.

Claims (2)
