Technical Field

[0001] The utility model relates to the technical field of rubber sealing strip production, in particular to a device for cutting waste materials at the head and tail of rubber sealing strips. Background Art

[0002] Rubber sealing strips are made of rubber or other elastic materials, have good sealing performance and elasticity, and can effectively prevent the leakage and intrusion of substances such as liquids, gases and dust. During the production process of rubber sealing strips, the uneven shapes of the ends require cutting of the sealing strips, so a cutting device is required.

[0003] The existing rubber sealing strip cutting device is mainly composed of a cutting mechanism, a feeding mechanism and a control system. When cutting the sealing strip, the feeding mechanism feeds the rubber sealing strip material into the cutting area, and the control system starts the cutting mechanism for cutting according to the detected position information. After the cutting is completed, the control system controls the feeding mechanism to send out the cut rubber sealing strip and prepare for the next cutting.

[0004] In the existing rubber sealing strip cutting device, when cutting the sealing strip, rubber is easily adhered to the cutting blade, and the adhered rubber reduces the sharpness of the cutting blade, thereby affecting the cutting effect and reducing the processing quality of the product. Therefore, a rubber sealing strip head and tail waste cutting device is proposed to address the above problem. Utility Model Content
