Tire retreading process and tire retreading equipment

Abstract

The invention discloses a tire retreading process and tire retreading equipment. The retreading process comprises the following steps of: (a), initial tire checking; (b), polishing and cleaning; (c), gluing and drying; (d), cushion rubber pasting; (e), tread rubber pasting; (f), vulcanization; and (g), product finishing, wherein a tire is conveyed through a vertical conveying track in coordination with suspension arms in every step. The tire retreading process has the advantages of scientificity, high efficiency, high quality of produced products and the like. The tire retreading equipment comprises the vertical conveying track, a tire detecting machine, a tire tread polishing machine, a tire checking machine, a gluing room, a drying room, a cushion rubber pasting machine, a tread rubber pasting machine, an envelope disassembling and assembling machine, a steel ring disassembling and assembling machine, a transitional rack and a tire vulcanization tank. The tire retreading equipment has the advantages of high production efficiency, low production cost, convenience for operation, safety and the like.

Description

Technical field: [0001] The invention relates to the technical field of tire retreading, in particular to a scientific, high-efficiency, high-quality tire retreading process and retreading equipment. Background technique: [0002] my country is the world's largest rubber consumer. With the rapid development of the automobile industry and mining machinery, my country has become the world's largest rubber consumer for seven consecutive years. At the same time, my country is a country that is very scarce in rubber resources. More than 70% of domestic natural rubber and more than 40% of synthetic rubber are dependent on imports, and the contradiction between supply and demand is very prominent. Due to the serious shortage of natural rubber and synthetic rubber resources, it also promotes the rapid development of tire retreading industry. [0003] Under the guidance and support of a series of national industrial policies, it has become a widespread consensus that waste tires are...

AI Technical Summary

Problems solved by technology

[0005] 1. The traditional tire retreading process is complex, labor intensive and costly

[0006] 2. As we all know, the quality of tires is relatively heavy. If in the process of tire retreading, the transportation and removal of tires are all carried out by manpower, this wastes a lot of manpower and the efficiency is relatively low.

In order to solve this problem, the transfer track is used in the prior art to transport the tires, but the effect is not obvious enough, and each transport track is set independently, and it is necessary to manually move the tire from one track to another. , and then transported to another station, such a transport track can only be used alone, and it is necessary to establish multiple transport tracks facing different stations, occupying a large space, and it is still impossible to change directions between the tracks

[0007] 3. The structure of the lid opening and closing device used to drive the opening and closing of the tank lid in the traditional tire vulcanization tank is very complicated, and the tank lid is manually tightly locked through multiple positions, so that the tank lid can be closed firmly, but the operation is cumbersome. It is very inconvenient; in addition, when the tire vulcanization tank is working, the operator needs to enter the tube body to place and position the tire, which is very inconvenient to operate

Most of the traditional tire vulcanization tanks are heated and vulcanized by installing steam heat dissipation pipes in the tank. The vulcanization temperature of this method is limited, and the circulation is not good, and a large amount of energy is required.

[0008] 4. When assembling the envelope, manual tools are generally used to expand the envelope, and then push the tire with the tread into the outer envelope. Therefore, the labor intensity is high and the operation time is long, which is not conducive to improving the renovation. efficiency, but also increases the cost of generating

[0009] 5. Grinding and pasting tire treads are only used for manual or semi-automatic processing, which requires a lot of manpower and material resources, and the labor intensity is high, resulting in low production efficiency and increased production costs.
