Description

Technical Field

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

[0002] Rubber products are manufactured using raw rubber as the primary raw material, along with various compounding agents, through processes including mixing, calendering, extrusion, molding, and vulcanization. Rubber products exhibit excellent elasticity and flexibility, returning to their original shape when subjected to stress and resisting deformation, making them widely used in various industries. The smaller the rubber product, the more difficult it is to cut the nozzle after molding and position the product during the molding process. This requires precise positioning and coordination with the cutter to ensure product yield and stability.

[0003] For example, application number 202220853492.9 discloses a shearing device for rubber products, which places the rubber product on a shearing table so that the rubber product pushes a clamp to compress a spring, and the rubber product is clamped and fixed by the rebound action of the spring, and an electric push rod pushes a shear knife to shear the rubber product by movement; this device achieves the goal of facilitating the fixation of the sheared rubber product by a fixed structure, and avoids the situation where the rubber product is cut obliquely due to the lack of a fixed structure. However, the smaller the rubber product, the more difficult it is to control the shearing at the water outlet after molding, and the required shearing accuracy is higher, thereby reducing work efficiency.
