AI Technical Summary

Technical Problem

Traditional cutting methods are difficult to cut silicone rubber efficiently, resulting in low cutting efficiency, poor product precision, and uneven edges. Furthermore, existing ultrasonic cutters are not ideal for cutting larger and thicker silicone rubber, requiring larger cutting tools to adapt to the process.

Method used

A cutting device with an ultrasonic structure is used, combined with a top pressure structure and a guiding and positioning system. The silicone rubber is tensioned by an arc plate and a top pressure roller, and ultrasonic vibration is used to assist cutting, ensuring cutting stability and accuracy and reducing rebound.

Benefits of technology

It improves the flatness and precision of the cutting edges, reduces cutting deviations and misalignment, and enhances cutting efficiency and product quality.

Abstract

The utility model discloses a cutting device used in a silicone rubber production process, which belongs to the technical field of silicone rubber production and comprises a transmission frame, a cutting fixing frame is fixedly connected onto the transmission frame, and a moving module is fixedly connected onto one side, close to the transmission frame, of the cutting fixing frame. A sliding seat of the moving module is connected with a positioning plate through a bolt, a telescopic cylinder is fixedly connected to the lower portion of the positioning plate, and a cutting structure is installed at the end of a telescopic rod of the telescopic cylinder. Meanwhile, a jacking roller in the jacking structure moves upwards to jack the silicone rubber, the silicone rubber is in a tensioned state through cooperation of the jacking roller and the jacking roller, the rebound phenomenon of the silicone rubber caused by self elasticity can be effectively reduced through the tensioned state, and it is guaranteed that the silicone rubber can be stably and accurately cut in a sliding mode in the transverse moving process of the cutting knife.
