Description

Technical Field

[0001] The utility model relates to the technical field of rubber calenders for tire production, in particular to a rubber calender for tire production. Background Art

[0002] Tires are essential parts for cars or electric vehicles, and are usually made of rubber. A rubber calender is needed during the tire production process to process the rubber into the required film. The calender is usually composed of two or more rollers arranged in a certain form. At a certain temperature, the rubber is pressed and stretched into a film of a certain thickness and surface shape, and can also be used to coat fiber cord canvas or steel cord with rubber.

[0003] During use of the existing rubber calender, it is not convenient to adjust the spacing between the top pressing roller and the bottom pressing roller to adjust the processing thickness of the rubber sheet, which reduces the processing range of the rubber calender.

[0004] After searching, a patent publication number CN217021162U is found to be a rubber calender that is easy to adjust. Although the rubber calender can solve the technical problems existing in the prior art, it still has certain disadvantages when used. When the rubber calender needs to adjust the extrusion width of the film, the user needs to manually rotate the screw to complete the adjustment. The manual operation reduces the degree of automation of the rubber calender equipment, and the equipment is less convenient to use. Utility Model Content
