[0002] Sealing gasket is an industrial part used to connect pipes and play a sealing role. At present, burrs will form on the surface of the sealing gasket after cutting. Since these burrs affect the surface quality of the workpiece, machine operation is required to remove the surface burrs. There are many kinds of deburring machines, which can be divided into physical deburring and chemical deburring according to the method. The chemical deburring methods currently mainly include pure chemical corrosion deburring and electrolytic deburring. The physical deburring methods currently mainly include vibration grinding deburring, rolling deburring, magnetic deburring machine and strong ultrasonic deburring. In physical deburring equipment, wire brushes or grinding wheels are mainly used to grind the burred parts to remove burrs.

[0003] A burr removal device for sealing gasket production disclosed in publication number CN212045588U has a novel structure, a simple structure, is easy to implement and effectively removes burrs on both sides of the sealing ring, improves production efficiency and yield rate, and is suitable for promotion.

[0004] However, this burr removal device for producing a sealing gasket has the following disadvantages:

[0005] When removing burrs from the gasket, the thickness of the gasket varies and the distance between the brush roller and the gasket cannot be adjusted according to the degree of fit between the brush roller and the gasket, thereby reducing the efficiency of burr removal.

[0006] When the brush roller needs to be maintained and repaired, the disassembly and assembly process of the brush roller is relatively complicated, which increases the disassembly and assembly time and reduces the maintenance and repair efficiency. Utility Model Content
