Description

Technical Field

[0001] The utility model relates to the technical field of rubber processing, in particular to a cutting device for rubber processing. Background Art

[0002] As an important industrial material, rubber is widely used in automobile manufacturing, tire production, machinery manufacturing, construction engineering, electronic products and other fields. The role of the cutting device in rubber processing is mainly to cut the rubber material into the required shape and size, and cut it into small pieces, strips or other geometric shapes of specific shapes to meet the design requirements of the product or the needs of subsequent processing technology.

[0003] In the process of implementing this application, the inventor found that there are at least the following problems in this technology:

[0004] (1) The cutting size cannot be adjusted. The cutting device can only adapt to rubber materials of a specific size. If you need to process rubber products of different sizes, you need to purchase multiple cutting devices of different specifications, which increases the equipment cost and occupies space. When the cutting device cannot adjust the size, it will lead to waste of rubber materials. If the size of the rubber material does not completely match the required size, additional cutting is required or part of the material is discarded, which increases material waste and cost.

[0005] (2) There are bumps or depressions on the unleveled rubber surface, which will increase the friction and resistance between the tool and the rubber during the cutting process, which will not only affect the cutting speed and efficiency, but also increase the wear of the tool and reduce the cutting quality. The uneven rubber surface will lead to uneven contact between the tool and the rubber material during the cutting process, which will cause the thickness of the cut rubber products to be inconsistent, with some parts being too thick and others being too thin, affecting the product quality and consistency, and causing the cut edges to be rough, easily producing burrs or cracks, affecting the appearance and quality of the product.
