Abstract

The invention belongs to a method for processing a sidewall film of an automobile tire. According to the design scheme provided by the present invention, the rubber material is added into the feeding port of the extruder, and the laminated film is formed after passing through the extruder, and then a guide device is set on the advancing direction of the laminated film, and the laminated film passes through the guide After the device enters the belt on the conveyor raceway, it fits with the sidewall on the belt. The invention can avoid the problem of poor bonding of hot and cold, and at the same time reduce energy consumption, manpower consumption and material consumption.

Description

Hot paste processing method for sidewall film

technical field

The invention belongs to a method for processing a sidewall film of an automobile tire.

Background technique

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 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. 2 in Figure 1 is a sidewall, which is a rubber part used in the tire manufacturing process.

Contents of the invention

The object of the present invention is to seek a thermal lamination processing method for sidewall films, so as to avoid the problem of poor lamination of hot and cold, and reduce energy consumption, manpower consumption and material consumption at the same time.

According to the design scheme provided by the present invention, the rubber material is added into the feeding port of the extruder, and the laminated film is formed after passing through the extruder, and then a guide device is set on the advancing direction of the laminated film, and the laminated film passes through the guide After the device enters the belt on the conveyor raceway, it fits with the sidewall on the belt.

The advantages of the present invention are: since the laminated film parts are all extruded in real time, the adhesiveness of the rubber material is better, so that the lamination process is avoided when it is in place, frequent replacement of film rolls is easy to produce air bubbles, joints, etc. problem, improving production efficiency and reducing the return of unqualified semi-finished products.

Detailed ways

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.

挤出机直接挤出胶片，并在线贴合。这样不仅解决了冷热贴合不好的问题，还同时对生产方面的能源消耗、人力消耗、物资消耗起到了很好的作用。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.

小型压延装置中的

小型挤出装置结合相应的圆形型胶口型板在线挤出胶片热贴合在半成品部件上。The present invention makes full use of

in a small calender

The small extrusion device is combined with the corresponding circular rubber mouth plate to extrude the film on-line and thermally paste it on the semi-finished parts.

小型挤出装置加上一个胶片导向装置，使得胶片能够准确贴合在位子上。工作时，在双复合挤出机挤出复合部件的同时

小型挤出装置挤出相应规格的胶片，在导向装置的作用下在生产线上直接贴合在一起。The present invention is under the situation that original process condition is unchanged, in

Small extruders plus a film guide allow the film to fit precisely on the seat. While working, while the dual compound extruder extrudes the compound part

The small extrusion device extrudes the films of corresponding specifications, and is directly pasted together on the production line under the action of the guide device.

Claims (1)
