Background technique

With the rapid development of the automobile industry, the demand for rubber parts in automobiles is also increasing, and the requirements for rubber parts in automobiles are also getting higher and higher. After the rubber parts are processed, in order to facilitate subsequent processing and manufacturing, the burrs on the edges of the rubber parts need to be cut off. In the prior art, most of the burrs of the rubber parts are cut off manually by using scissors, which has low work efficiency and high labor cost. Moreover, when cutting, there is a problem of inaccurate cutting, which leads to the occurrence of more cutting of rubber parts or less cutting of burrs. When the rubber parts are cut too much, it is easy to lead to poor product quality, increase the scrap rate, and increase the processing cost. When the burr of the rubber part is less cut, it needs to be reworked to remove the burr again, the rework rate is increased, the processing efficiency is reduced, and the processing cost is increased. There are also devices on the market that remove burrs by machining. Although the processing efficiency is improved to a certain extent and the processing cost is reduced, there are also problems: most of these devices are driven by motors or hydraulics, and their lubricating oil, hydraulic oil, etc. The gas is easily dispersed in the air, which can easily cause environmental pollution and damage the health of workers.
