Abstract
Description
Technical Field
[0001] The utility model relates to a multifunctional cutting device for bevel cutting the edge of an inner liner layer. Background Art
[0002] The tire inner liner layer is located between the carcass and the inner wall of the tire and is mainly composed of a gas barrier layer and a transition layer. The inner liner layer component mainly plays the role of preventing the tire from leaking air and protecting the carcass. During the forming of the tire blank, according to the process requirements, the inner liner layer and other components should be closely bonded to prevent the problem of trapped air during bonding. How to avoid the problem of trapped air between components is one of the key factors in manufacturing high-quality tires.
[0003] According to the process requirements, during the production of the inner liner layer component, the industry generally uses the traditional (circular knife) 90° vertical cutting form to cut the edge of the inner liner layer. The cutting tool uses a circular knife design, and the cutting angle is vertical cutting. When cutting at a vertical angle, affected by the edge thickness of the product, the edge of the inner liner layer after cutting is a right-angle surface. When the inner liner layer produced by this process requirement is used for the forming of the tire blank, it is extremely easy to have abnormal trapped air at the inner bead part of the tire blank. It is not easy to find with the naked eye the tire blank with abnormal trapped air at the bead. After vulcanization, the tire will have bead air bubbles and bead delamination defective products, which will cause greater quality and cost losses to the company. Summary of the Utility Model
