A fixing frame 205 is threaded onto the outer surface of the rotating screw 203. An electric push rod 206 is embedded in one side of the fixing frame 205. One end of the 06 is connected to a servo motor 207, and the output end of the servo motor 207 is connected to a grinding wheel 208. A feeding assembly 3 is connected to one side of the mounting frame 1. The feeding assembly 3 includes two sets of sealed bearings 301. The inner ring of each set of sealed bearings 301 is connected to a rotating wheel 302. A set of rotating wheels 302 are connected via a conveyor belt 303. One end of each rotating wheel 302 is connected to a reduction motor 304. Two electro-hydraulic rods 305 are embedded on one side of the mounting frame 1. One end of component 5 is connected to a pressure plate 306. The rotation of the servo motor 207 drives the grinding wheel 208 to rotate, and with the pushing force of the electric push rod 206, it easily pushes the grinding wheel 208 into contact with the corrugated cardboard box. Furthermore, the rotation of the power motor 204 drives the rotating screw 203 to rotate within the inner ring of the bearing seat 202. The rotating screw 203 is threadedly connected to the fixing frame 205, and the fixing frame 205 is slidably connected to the mounting groove 201, which allows the grinding wheel 208 to move... The process of sanding the burrs on corrugated cardboard boxes during operation reduces labor. The rotation of the geared motor 304 drives a rotating wheel 302 to rotate within the inner ring of the sealed bearing 301. This rotating wheel 302 is connected to the conveyor belt 303 via transmission, which enables the conveyor belt 303 to automatically feed the corrugated cardboard boxes. In addition, the pushing force of the electric hydraulic rod 305 can fix the pressure plate 306 to the corrugated cardboard box, preventing displacement during sanding and improving the quality and efficiency of sanding.
[0025] In this embodiment, two support frames 8 are connected to one side of the mounting frame 1. Each support frame 8 has two mounting holes on one side. The support frames 8 and mounting holes can be used to easily fix the device to the ground. Two sets of pressure bearings 6 are embedded in the inner wall of the mounting frame 1. The inner ring of each set of pressure bearings 6 is connected to a rotating wheel 7. The pressure bearings 6 and rotating wheels 7 can prevent the corrugated cardboard box from being worn during movement. A reinforcing block 9 is connected to one side of the mounting frame 1. One side of the reinforcing block 9 is connected to the inner wall of the mounting frame 1. The reinforcing block 9 can improve the load-bearing capacity of the mounting frame 1.

Two indicator lights 4 are connected to one side of the mounting frame 1, and the outer surface of the power motor 204 is connected to one side of the mounting frame 1. The indicator lights 4 can be used to conveniently indicate that the equipment is working.
[0027] Working principle: First, the device is moved to the location of use and connected to the power supply. The required program is set by pressing the external control display screen 10. Simultaneously, the corrugated cardboard box to be sanded is placed on the conveyor belt 303, specifically with the edge of the cardboard box horizontally aligned with the sanding wheel 208. The rotation of the reduction motor 304, in conjunction with a set of rotating wheels 302 connected to the conveyor belt 303, moves the cardboard box to the designated position. Subsequently, the pushing force of the electric hydraulic rod 305 causes the pressure plate 306 to press the cardboard box in place. The servo motor 207 drives the grinding wheel 208 to rotate, and the pushing force of the electric push rod 206 causes the grinding wheel 208 to contact the edge of the corrugated cardboard box. At the same time, the power motor 204 rotates, and in coordination with the rotation of the power motor 204, the rotating screw 203 can rotate in the inner ring of the bearing seat 202. Then, the rotation of the rotating screw 203, in conjunction with its threaded connection with the fixing frame 205, enables the fixing frame 205, the servo motor 207 and the grinding wheel 208 to grind and eliminate the burrs of the corrugated cardboard box while moving. The above is the complete usage process of this utility model.
[0028] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
