[0019] Through the above technical solution, the rust residue, impurities and other waste generated during the rust removal process can fall into the waste box 20 for centralized collection through the second waste port 401 on the fixed frame 4 and the first waste port 102 on the workbench 1. With the help of the detachable design of the dovetail structure, the waste box 20 can be easily disassembled to clean the internal waste, ensuring a clean working environment for the equipment and facilitating continuous and efficient operation.

[0020] The working principle of this utility model is as follows: First, place the workpiece to be derusted on the fixed frame 4. Start the first electric telescopic rods 5 on both sides of the inner wall of the fixed frame 4 to drive the clamping plate 6 to extend and retract to clamp the workpiece. Then start the first motor 201 on the side wall of the workbench 1 to drive the lead screw 2 in the equipment slot 101 to rotate. The lead screw 2 drives the threaded transmission slider 3 to move, thereby driving the fixed frame 4 and the clamped workpiece to move into the mounting frame 7.

[0021] After the workpiece enters the mounting frame 7, it first passes through the brush 9 whose height is adjusted by the second electric telescopic rod 8. The second motor 10 drives the brush 9 to rotate, cleaning the floating dust and impurities on the surface of the workpiece. Then, the workpiece passes through the coarse grinding roller 12 whose height is adjusted by the third electric telescopic rod 11 and the fine grinding roller 15 whose height is adjusted by the fourth electric telescopic rod 14. The third motor 13 drives the coarse grinding roller 12 to perform coarse grinding and rust removal, and the fourth motor 16 drives the fine grinding roller 15 to perform fine grinding and polishing.

[0022] During this process, the dust collection devices 18 on both sides of the top of the mounting frame 7 collect dust and impurities generated during the operation in real time through the suction head 1801. After fine grinding, the workpiece continues to move between the fine grinding roller 15 and the trapezoidal sponge block 17. The blowing device 19 on the top of the mounting frame 7 blows away residual rust residue onto the surface of the workpiece through the connecting pipe 1901 and the blowing head 1902. Then, the workpiece passes through the trapezoidal sponge block 17 to complete the surface wiping. The rust residue, impurities and other waste generated during the rust removal process will be blown away by the blowing head 1902 and fall into the waste box 20 at the bottom of the worktable 1 through the second waste port 401 on the fixed frame 4 and the first waste port 102 on the worktable 1. When the waste accumulates to a certain amount, the waste box 20 can be disassembled with the help of the mortise and tenon structure of the dovetail groove 2001 and the dovetail protrusion 103, the internal waste can be cleaned and then reinstalled to ensure continuous operation of the equipment.
