Problems solved by technology

The disadvantages of this method are: due to the lamination of hot and cold glue materials, the adhesion is poor, and the amount of plastic waste that plays a role in keeping the film fresh in the film production process is large; It is easy to produce bubbles, joints and other problems, which increases the return of parts and reduces production efficiency

Embodiment Construction

[0008] In the feed port 10 of the extruder 9, add the conventional sizing material 11 commonly used for the production of automobile tire sidewall films, form the laminating film 8 after passing through the extruding device 9, and then set it on the advancing direction of the laminating film 8 A guiding device 7, the pasting film 8 enters the belt of the conveying raceway 6 after passing through the guiding device 7, and is bonded with the sidewall 5 positioned on the belt. The guide 7 can be a guide roller.

[0009] The present invention combines existing technological conditions, utilizes The extruder directly extrudes the film and laminates it online. This not only solves the problem of poor hot and cold bonding, but also plays a very good role in energy consumption, manpower consumption, and material consumption in production.

[0010] The present invention makes full use of in a small calender The small extrusion device is combined with the corresponding circular r...

Abstract

The invention belongs to the process of producing the tyre side film. The sizing material is put into the feeding hopper of the extruder to form the binding film. Then a leading device is set in the heading of the film to lead the film to the conveyer belt and bind with the tyre side. The invention can avoid the problem of the cool-heat binding and decrease the cost of the energy, the human power and material.

Description

technical field [0001] The invention belongs to a method for processing a sidewall film of an automobile tire. Background technique [0002] In the production process of all-steel wire radial truck tires, the extrusion section undertakes the important task of supplying four semi-finished parts: tread, sidewall, triangle and cushion rubber. In the prior art, the processing technology for the sidewall is: after the extrusion calendering production line extrudes the laminated film (produced on another production line), it is wound on the unwinding device, and then the laminated film is released from the It is pulled out from the roll device, and the pressing roller 4 and the conveying raceway 1 are pressed together at the A station and B station of the production linkage line to bond the laminated films of corresponding specifications output by multiple processes together. In order to protect the composite surface of the sidewall and improve the quality of the product. The di...
