The mounting frame 3 is a "U" - shaped structure with an opening facing downwards, and the two sides of the bottom of the mounting frame 3 are respectively fixed on the tops of two different support frames 2;

[0026] A telescopic cylinder 8 is fixedly connected to the top center of the mounting frame 3. The telescopic end of the telescopic cylinder 8 passes through the mounting frame 3 and is located inside the mounting frame 3. The telescopic end of the telescopic cylinder 8 is connected to the top center of the top plate 9. Connecting rods 10 are provided at the four corners of the bottom of the top plate 9. The bottom of the connecting rods 10 is connected to the four corners of the top of the bottom plate 11 respectively. A motor 12 is fixedly connected to the top center of the bottom plate 11. A rotating rod is provided at the bottom output end of the motor 12. The rotating rod passes through the bottom plate 11 and is located below the bottom of the bottom of the bottom plate 11. A grinding wheel 13 is provided at the bottom of the rotating rod.

[0027] Specifically, the above structure is a sander of the prior art. The specific structure of the conveyor belt 1 and how the grinding wheel 13 grinds the plate will not be described in detail here.

[0028] Furthermore, the top two ends of the mounting bracket 3 are horizontally provided with sliding guide rails 18, the bottom of the sliding guide rails 18 is provided with a sliding inner cavity 19, and a lead screw 14 is provided between the two ends of the sliding inner cavity 19.

[0029] Furthermore, a rotating shaft 4 is provided at the same end of the two lead screws 14. The other end of the rotating shaft 4 passes through the mounting bracket 3 and is located on the side of the outer surface of the mounting bracket 3. A transmission wheel 5 is sleeved on the front end surface of the rotating shaft 4. The back of the transmission wheel 5 is in contact with the surface of the mounting bracket 3. The two transmission wheels 5 are connected by a transmission belt 6.

[0030] Furthermore, the other end of one of the rotating shafts 4 is connected to the output end of the drive motor 7, and the drive motor 7 is fixed to the mounting bracket 3 by a fixing mechanism.

[0031] Furthermore, sliding blocks 15 are sleeved at both ends of the surface of the lead screw 14. The sliding blocks 15 are fitted and slidably connected in the sliding inner cavity 19. A connecting plate 16 is provided at the bottom of the sliding block 15. The two connecting plates 16 on the same side are connected to the top ends of the limiting plate 17.

[0032] Furthermore, the lead screw 14 is a bidirectional threaded rod.

[0033] Working Principle: This utility model discloses a sanding machine for sheet metal processing. Based on existing sanding machines, it adds limiting plates 17 on both sides of the top of the conveyor belt 1. The distance between the two limiting plates 17 can be adjusted appropriately by the drive motor 7. The distance needs to be adjusted according to the size of the sheet metal, thus limiting the size of sheets. Specifically, in use, the sheet metal is placed on the conveyor belt 1 without opening it, and then the drive motor 7 is started. The rotation of the drive motor 7 will cause the rotating shaft 4 to rotate, which in turn will cause the lead screw 14 to rotate. Simultaneously, the rotation of the shaft 4 will also cause the transmission wheel 5 to rotate. The rotation of the transmission wheel 5 will cause another transmission wheel 5 to rotate through the transmission belt 6, thereby causing the two lead screws 14 to rotate. At this time, through the principle of lead screw transmission, and since the lead screw 14 is a bidirectional threaded rod, the two sliding blocks 15 on the surface of the lead screw will move towards the middle of the lead screw 14. Finally, the top two limit plates 17 of the conveyor belt 1 will move towards the middle or the sides. When both limit plates 17 are in contact with the sides of the plate, the drive motor 7 is turned off to prevent the plate from shifting during grinding, which would result in an unsatisfactory grinding effect.

[0034] It is worth noting that the entire device is controlled by a controller. Since the controller is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.
