Description

Technical Field

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

[0002] Rubber is a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce large deformation under very small external force. It can return to its original shape after the external force is removed. Rubber is a completely amorphous polymer with a low glass transition temperature and a molecular weight that is often large, greater than hundreds of thousands. Rubber products are widely used in industry or all aspects of life. Rubber products have a wide range of uses. Rubber sealing rings are used between machinery and parts to increase the sealing and protection between machinery. In the production process of rubber sealing rings, a cutting device is required to cut the formed rubber tube into sealing rings of specified width.

[0003] When the current cutting device for rubber sealing ring production is used, the two ends of the rubber tube are usually clamped and fixed, and then the high-speed rotating cutting head driven by a motor is operated to cut the rubber tube. When the cutting device of this structure is used, due to the lack of a supporting mechanism for supporting the rubber tube, downward pressure is inevitably generated during the cutting operation, which easily causes deformation of the rubber tube and reduces the cutting accuracy.
