[0026] As a further implementation of the present invention, the shielding mechanism 6 includes a fixed bracket 61, which is fixedly connected to the motor box 3 by a fixing bolt 63, and shielding plates 62 are fixedly connected to both sides of the upper end of the fixed bracket 61, and a through hole 64 is provided at the bottom end of the fixed bracket 61. By setting the shielding mechanism 6, one end of the air delivery mechanism 7 can be positioned, and at the same time, the problem of dust floating upward when the dust on the surface of the polishing belt 4 is blown off can be prevented;

[0027] As a further implementation of the present invention, the fixing bracket 61 is U-shaped, the fixing bracket 61 is installed on the outside of the polishing belt 4, the shielding plate 62 is fixed to the upper end of the polishing belt 4, and the through hole 64 is arranged on the lower side of the polishing belt 4.

[0032] Working process: When the equipment is in operation, the external power supply is energized. When the polishing belt 4 is used to remove burrs and polish the door lock panel, the driving roller 5 can drive the polishing belt 4 to rotate stably under the drive of the motor box 3. When the polishing belt 4 rotates, it contacts the door lock panel to perform polishing. During this process, the elliptical wheel 8 rotates along with the rotation of the driving roller 5.

In the process of the up and down movement of the second piston rod 711, the sealing circular plate 79 will be driven to move up and down. In the process of the upward movement of the sealing circular plate 79, the gas inside the cylinder 71 is blown to the surface of the polishing belt 4 through the nozzle 77, so that the dust attached to the surface of the polishing belt 4 can be processed, thereby improving the polishing effect of the polishing belt 4 during the operation. In the process of the downward movement of the sealing circular plate 79, the gas enters the cylinder 71 through the one-way valve 710. In this cycle, the surface of the polishing belt 4 can be cleaned continuously. At the same time, during the overall operation of the device, the dust floating in the air above the device during the polishing process can be collected and processed through the negative pressure dust removal box 1, thereby further improving the environmental quality around the workstation.
