The working principle is as follows: firstly, metal products are placed on a first conveyor belt 11, then the first conveyor belt 11 starts to work, the metal products are driven to move, meanwhile, the polishing assembly carries out rough polishing treatment on the metal products entering the device, then a power supply is connected to enable an air pump 15 to start to work, a T-shaped pipe 16 communicated with the air inlet end of the air pump 15 pumps air outside the U-shaped block 13 into an air inlet groove 14, then the air is discharged between the first conveyor belt 11 and a second conveyor belt 12 through an L-shaped pipe 17, when the metal products enter the second conveyor belt 12 through the first conveyor belt 11, scraps on the metal products can be blown off by the L-shaped pipe 17 to be blown into a collecting box 20, then the metal products move through the second conveyor belt 12, and fine polishing is carried out again. According to the scheme, the situation that the sanding machine cannot uniformly sand the metal product due to the fact that the sanded scraps remain on the surface of the metal product and the surface of the sanding machine cannot be attached to the surface of the metal product can be reduced in the working process of the sanding machine.

In order to provide power for the first conveyor belt 11 and the second conveyor belt 12 in the use process, the transmission assembly at least comprises a first motor 19, an output shaft of the first motor 19 extends to be coaxially connected with the center of the front surface of the driving wheel of the first conveyor belt 11, a second motor 2 is arranged on the right side of the first motor 19, an output shaft of the second motor 2 extends to be coaxially connected with the center of the front surface of the driving wheel of the second conveyor belt 12, the first motor 19 in the cavity 18 drives the driving wheel on the first conveyor belt 11 to rotate, so that the first conveyor belt 11 works, and the output shaft of the second motor 2 drives the driving wheel on the second conveyor belt 12 to rotate, so that the second conveyor belt 12 works.

Considering that metal products are placed on the first conveyor belt 11 and need to be polished, the polishing assembly at least comprises a pair of polishing boxes 21, a telescopic groove 22 is formed in each polishing box 21, a hydraulic cylinder 23 is installed on the top wall of each telescopic groove 22, a movable plate 24 is fixedly connected with a telescopic rod of each hydraulic cylinder 23, the movable plate 24 is slidably connected with the side wall of each telescopic groove 22, a third motor 25 is installed on the upper surface of each movable plate 24, a rotating block 26 is rotatably connected to the center of the lower surface of each movable plate 24, an output shaft of each third motor 25 extends to be coaxially connected with the center of the upper surface of each rotating block 26, a polishing block 27 is arranged on the lower surface of each rotating block 26, the movable plates 24 are driven to move through hydraulic cylinders 23 in the polishing boxes 21, and meanwhile the rotating blocks 26 are driven to rotate by the cooperation of the third motors 25, and the polishing blocks 27 on the rotating blocks 26 can polish the metal products. The sanding assembly above the second conveyor 12 is of the same construction as the sanding assembly above the first conveyor 11.

And the polishing block 27 on the device has larger abrasion after long-time use, so that the polishing effect is poor, a threaded column 28 is fixedly connected to the center of the upper surface of the polishing block 27, a threaded groove for threaded connection of the threaded column 28 is formed in the center of the lower surface of the rotating block 26, and after the polishing block 27 is used for a long time, the polishing block 27 can be rotated, so that the threaded column 28 on the polishing block 27 is in threaded connection with the threaded groove on the rotating block 26, and the polishing block 27 is replaced.

In operation, the collection box 20 is used for collecting the scraps of the polished metal products and then processing the scraps, so that the rear surface of the conveying box 1 is provided with a through groove for the collection box 20 to be pulled, the through groove is communicated with the mounting groove 10, the collection box 20 is pulled out through the through groove, and the metal scraps in the collection box 20 are uniformly processed.

In addition, the thickness of different metal materials is different, and scraps in the polishing process are prevented from flying out, so that one surface, away from each other, of two polishing boxes 21 is provided with a reserved groove for sliding of the corrugated plate 29, the reserved groove is communicated with the telescopic groove 22, the corrugated plate 29 can be used for polishing according to metal products of different sizes, and scraps in polishing can be intercepted when the metal products enter the telescopic groove 22 and then are polished.

When the sanding machine in this embodiment is specifically used, when the device needs to polish a metal product, the metal product is firstly placed on the first conveyor belt 11, then the first motor 19 in the cavity 18 works, so that the first conveyor belt 11 starts to work and drive the metal product to move, the telescopic rod of the hydraulic cylinder 23 drives the moving plate 24 to descend, at this time, the third motor 25 starts to work, the output shaft of the third motor 25 drives the rotating block 26 and the polishing block 27 to rotate, and the polishing block 27 carries out rough polishing treatment on the metal product. The air pump 15 starts to work during polishing, the T-shaped pipe 16 communicated with the air inlet end of the air pump 15 pumps air outside the U-shaped block 13 into the air inlet groove 14, the air is discharged between the first conveyor belt 11 and the second conveyor belt 12 through the L-shaped pipe 17, when metal products enter the second conveyor belt 12 through the first conveyor belt 11, scraps on the metal products can be blown into the collecting box 20 by the air blown out by the L-shaped pipe 17, then the metal products move through the second conveyor belt 12 and are polished again, when the sizes of the metal products are different, the sizes of the metal products entering the device can be adjusted through the corrugated plates 29 on the polishing box 21, and scraps generated in the polishing process of the polishing block 27 can be intercepted. The sander solves the problem that the scraps polished in the working process of the sander can remain on the surface of a metal product, so that the sanding block cannot be attached to the surface of the metal product, and the sander cannot uniformly polish the metal product.
