Compounding device for inner liners

Abstract

The invention discloses a compounding device for inner liners, which is used for tyre production. The compounding device comprises a second conveying belt, and a press roll device, wherein the press roll device comprises a support and a second press roll; the second press roll is arranged on the support by means of being capable of moving up and down, and located just above the second conveying belt; and the axis of the second press roll is vertical to the rotating direction of the second conveying belt. During the use of the compounding device, the jointed inner liners are placed on the second conveying belt, and then the second press roll capable of moving up and down is moved to a proper height, and used for performing press fit on the inner liners on the second conveying belt; and simultaneously, the second conveying belt is rotated, so that the inner liners are subjected to press fit sequentially via the second press roll until press fit for all the inner liners is finished. Compared with the operation for press fit carried out by an operator using a manual press wheel, the compounding device for inner liners provided by the invention has the advantage that multilayer glue components in the inner liners are uniformly compacted section by section, so as to realize no air bubbles and no wrinkles; and therefore, the quality of compounding the inner liners can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of tire inner liners, in particular to an inner liner compounding device. Background technique [0002] Tires are circular elastic rubber products that are rolled on the ground and rolled on various vehicles or machinery. Usually installed on metal rims, it can support the body, buffer external impact, realize contact with the road surface and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions, and they are subjected to various deformations, loads, forces, and high and low temperature effects during driving, so they must have high load-bearing performance, traction performance, and cushioning performance. [0003] The role of the tire inner liner in the tire is to prevent the tire from leaking and to prevent the inner tire pad from sliding in the tire cavity. The inner liner generally has two layers: the airtight layer and the transition layer. The inner ...

AI Technical Summary

Problems solved by technology

First of all, multiple layers of inner lining rubber parts, including airtight layer, transition layer, etc., are manually spliced ​​together, and then the operator uses a hand pressure wheel to press them together. The process of pressing is called compounding. During manual compounding, Not only the amount of labor is huge, but also the production of the inner lining will produce unstable factors such as wrinkles, air bubbles, delamination, and contamination of rubber parts that affect the quality of the process, resulting in a large amount of labor and rubber waste.
