Description
Technical Field
[0001] The present application relates to a calendering deviation-correcting and cutting device for a tire inner liner, belonging to the technical field of tire manufacturing devices. Background Art
[0002] The inner liner of the tire is composed of two layers of rubber, an airtight layer and a transition layer. The airtight layer can prevent the penetration of moisture and gas to ensure a constant gas pressure inside the tire. The transition layer is used to enhance the adhesion between the airtight layer and other components to prevent delamination of the components. In the prior art, most of these two layers of materials are calendered by one device, first cut to a fixed size, and then compounded. During the compounding process, a set of correction devices are required to ensure that the two layers of materials are aligned during the bonding process. The traditional correction method is to correct the conveyor belt. The problem with this method is that the material will be folded when the correction amplitude is large, resulting in a poor correction effect. Therefore, it is necessary to design a calendering correction cutting device that can solve the problem of poor cutting consistency in the traditional cutting method, and can solve the problem of material wrinkles caused by excessive correction process, so as to improve the compounding quality and work efficiency.

[0079] The raw materials are first calendered by the calendering mechanism to compact the raw materials into a uniform plate-shaped lining layer material, and then enter the transition layer cutting mechanism for cutting and deviation correction, and then enter the airtight layer cutting mechanism for cutting and deviation correction, and then cool and curl them before being put into storage.
[0080] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
