Rubber tire manufacturing process

Abstract

The invention relates to a rubber tire manufacturing process. The process uses cord fabric cooling equipment, and the cord fabric cooling equipment comprises a bottom plate, a mounting plate, a firstcooling device, a second cooling device, a connecting pipe and a driving device. The specific process for preparing a rubber tire by adopting the cord fabric cooling equipment comprises the followingsteps of banburying, preparing a rubber part, forming the tire, performing vulcanizing and performing final inspecting. The first cooling device and the second cooling device which are different in temperature are arranged to conduct graded cooling treatment on cord fabric, the cooling efficiency can be improved, and meanwhile the situation that the elasticity of the cord fabric becomes poor due to the fact that the temperature of the cord fabric drops too fast is avoided; and after the temperature of cooling water of the first cooling device rises to a certain degree, the cooling water can beused for the second cooling device to cool the cord fabric, the overall water consumption is reduced, the contact area and the attachment tightness of the cord fabric and the surface of a cooling roller are increased through an auxiliary mechanism in the cooling process, the heat exchange speed is increased, and the cooling effect is guaranteed.

Description

technical field [0001] The invention relates to the field of rubber tires, in particular to a rubber tire manufacturing process. Background technique [0002] The manufacturing process of tires usually includes steps such as mixing, preparation of rubber parts, molding, vulcanization and testing. The preparation of rubber parts includes the forming of cords. The cords are the cloth lining the tires. It's called curtain cloth. [0003] After the cord is formed, its temperature is high. In order to speed up the cooling and shaping of the cord, it needs to be cooled. However, there are some problems in the process of cooling the cord with existing equipment: [0004] (1) When the cord is moved by the traction of the traction equipment, the cord slides relative to the surface of the cooling roller. Since the surface of the cooling roller is a circular arc surface structure, the traction force applied by the traction equipment to the cord is set along the tangential direction of...

AI Technical Summary

Problems solved by technology

[0004] (1) When the cord is moved by the traction of the traction equipment, the cord slides relative to the surface of the cooling roller. Since the surface of the cooling roller is a circular arc surface structure, the traction force applied by the traction equipment to the cord is set along the tangential direction of the cooling roller surface, so The cord is often unable to fully adhere to the surface of the cooling roller, which leads to insufficient heat exchange between the cooling roller and the cord, reducing the cooling effect;

[0005] (2) When using the existing cooling equipment to cool the cord, in order to reduce the cost, most manufacturers often only have one cooling roller. In order to improve the cooling efficiency, some manufacturers will set up multiple cooling rollers to cool the cord at the same time, but such a Consumption of cooling water is increased, resulting in waste of water resources
