(54) DEVICE FOR THERMAL TREATMENT OF TAPE RUBBER MATERIAL

one

The invention relates to the processing of rubber and can be used for the heat treatment of a band of rubber material, such as cooling or vulcanization of long rubber products.

According to the main author. St. No. 497152, a device for heat treatment of tape rubber material is known, comprising a chamber filled with the processing medium, a rolling and rolling processing material installed therein, a working member in the form of drive belt conveyors and the drives of the latter.

The device has separating elements rolled into rolls on seamer-folding coils and attached with free ends to the belts of the driving belt conveyors.

In the known device, the separating elements are made in the form of profiled elastic tapes having projections and depressions 1 on both sides.

In the process of heat treatment, especially when vulcanizing tape rubber material, on such a device, the protrusions of the separation elements under the action of their own weight and strength

The seals of the upper layers of the material in the roll are embedded in a rubber sheet, heated to high temperatures (over 100 ° C) and heated to high temperatures (over 100 ° C). As a result, the impact of the protrusions of the separating elements on the surface of the rubber sheet remains indented, which is a serious defect, and in some cases, for example, during vulcanization, an incorrigible product.

The purpose of the invention is to increase the quality of the surface of the rubber band material.

This goal is achieved by the fact that, in a device for heat treatment of a tape rubber material, each of the separation elements is made in the form of 15 two flexible metal bands arranged in parallel with each other with elastic gaskets fixed between them.

In the proposed device, contact between the separating element and the rubber sheet along the plane H is ensured by uniformly distributing the load on the rubber sheet on the own weight of the separating element and the weight of the layers of the rolled up material. With this completely

damage to the surface of the rubber sheet in contact with the separating element is avoided. Metal tapes have a high thermal conductivity and do not affect the rate of heat transfer between the coolant and the rubber sheet.

FIG. 1 shows the proposed device, a general view; in fig. 2 - the same plan; in fig. 3 shows the node I in FIG. one.

A device for heat treatment of a tape rubber material contains a chamber 1 filled with a processing medium, a coolant or a coolant, a rolling and rolling processing material installed in it, a working member in the form of drive belt conveyors 2 and 3 and their drives (not shown). Near the chamber 1, there are installed rolling-unrolling coils 4 and 5 with separating elements b and 7 rolled into rolls. Elements 6 and 7 are made in the form of two flexible metal bands 8 arranged parallel to each other, between which elastic gaskets 9 are fixed along the length of the strips (FIG. 3). At the entrance to chamber 1, guide rollers 10 and 11 are installed, and at the exit from it are pairs of zero rolls 12 and 13 for selecting separating elements together with material from belt conveyors 2 and 3.

The operation of the device is described by the example of using it to cool the rubber compound.

The rubber band 14 is cut from the rollers 15 by the knives 16, through the guide roller 11 is fed into the water-filled chamber 1 to the moving conveyor belt 3 and rolled on the last layer together with the separating element 7, rolled up with the rolls 5. After rolling the entire hinge of the rubber mixture on the conveyor belt 3 is turned off and the rolled mixture is cooled.

In order to improve heat transfer, compressed air is fed into the chamber, which increases the movement of water into chamber 1.

Then, from the rollers 15 in the form of a belt 17, the next weight of the mixture is removed, through the guide roller 10 is fed to the moving belt of the conveyor 2 and rolled layer by layer onto the latter together with the separating element 6.

At this time, the cooled belt 14, together with the separating element 7, is pulled by the thin rollers 13 from the conveyor 3 and fed to the cutting device 18, which is cut into pieces of a given length and placed in the container 19. The separating element 7 rolls onto the Coil 5. Next, the next rubber band rolls over to the conveyor 3, and the process repeats.

The use of the invention allows, while ensuring high productivity of the process, to eliminate the surface defects of the rubber sheet that occur during the heat treatment of the material.
