The chain transmission structure drives one or more rotating shafts to rotate, so that the conveyor belt moves in a circular motion on one or more rotating shafts. In order to increase the friction with the metal plate, the outer surface of the conveyor belt is provided with a pattern or convex point.

[0047] A polishing chamber 2 and a cover 4 are provided on the top of the conveyor 1. The front and rear sides of the polishing chamber 2 are through to form an inlet and an outlet. One side of the cover 4 is connected to the outlet of the polishing chamber 2, and the other side is connected to a cleaning chamber 3, so that the polishing chamber 2, the cover 4 and the cleaning chamber 3 are sequentially communicated. The metal plate is placed on the conveyor belt of the conveyor 1, and the metal plate is driven by the conveyor belt to pass through the polishing chamber 2, the cover 4 and the cleaning chamber 3 in turn. When the metal plate is driven into the polishing chamber 2, the upper surface of the metal plate is polished. When the metal plate passes through the cover 4 and enters the cleaning chamber 3, the conveyor belt of the conveyor 1 and the polished surface of the metal plate are covered with metal dust and cleaned. The shielding of the polishing chamber 2 and the cover 4 can limit the diffusion of most dust generated by polishing to the outside, so that the dust finally falls on the conveyor belt of the conveyor 1 and the polished surface of the metal plate.

[0051] Further, the maintenance opening 7 is arranged on the top of the polishing chamber 2 vertically corresponding to the part of the polishing assembly 5, and a cover 9 is rotatably connected to the maintenance opening 7, and the cover 9 can be rotated to open or close the maintenance opening 7; the top of the polishing chamber 2 is also provided with a slot for supporting the movement of the pull plate 8, and the pull plate 8 extends into the bottom end of the polishing chamber 2 through the slot, and two link frames 11 are connected to the bottom end of the polishing chamber 2, one end of each of the two link frames 11 is fixed with part of the door assembly 6, and the other end of each of the two link frames 11 is fixed with the polishing assembly 5, pulling the pull plate 8 to move on the slot can drive the polishing assembly 5 and the door assembly 6 to move up and down through the two link frames 11, and the upward movement of the polishing assembly 5 can make any thickness of the metal plate below the polishing assembly 5 to be polished, and further upward movement close to the maintenance opening 7, so that the polishing assembly 5 can be exposed by opening the maintenance opening 7 through the cover 9, so as to replace the severely worn abrasive and the shaft of the polishing assembly 5.

[0052] As shown in Figure 3 and Figure 4 , the door assembly 6 includes a sleeve plate 61 and a moving plate 62, the sleeve plate 61 is fixed on the entrance of the polishing chamber 2 and is sleeved outside the moving plate 62, and the bottom of the moving plate 62 is rotatably connected with a roller shaft; the polishing assembly 5 includes a polishing roller 51, a first connecting piece 52, a second connecting piece 53 and a motor 54, the first connecting piece 52 and the second connecting piece 53 are respectively detachably connected at both ends of the polishing roller 51, the second connecting piece 53 is connected with the motor 54 in a compressible length, and the motor 54 is externally fixed with a machine shell 58, so that the motor 54 is protected in the machine shell 58;

[0053] The first connecting piece 52 and the second connecting piece 53 are connected on both sides of the inside of the polishing chamber 2 through the sliding guide 10, so that the polishing roller 51 is fixed between the first connecting piece 52 and the second connecting piece 53 through the interval limitation of the two sliding guides 10;

[0054] Two sliding guides 10 are each composed of a sliding shaft fixed vertically in the polishing chamber 2 and a sliding sleeve sleeved outside the sliding shaft;

[0055] The moving plate 62 is moved upward by pulling the plate 8 and the two connecting frames 11 to retract into the sleeve plate 61, and the polishing assembly 5 is moved upward by the two sliding guides 10. Specifically, the first connecting piece 52 is fixed with the sliding sleeve of one of the sliding guides 10, and the machine shell 58 is fixed with the sliding sleeve of the other sliding guide 10, so that the sliding sleeve is moved on the sliding shaft by the first connecting piece 52 or the machine shell 58;

[0056] When the abrasive, i.e. the polishing roller 51, needs to be replaced, the polishing roller 51 is moved close to the access hole 7 and kept in position on the sliding shaft, and the second connecting piece 53 is compressed to allow one end of the polishing roller 51 to be detached from the second connecting piece 53. After the other end of the polishing roller 51 is detached from the first connecting piece 52, the polishing roller 51 is not restricted by the first connecting piece 52 and the second connecting piece 53, and can be removed from the access hole 7. When a new polishing roller 51 is installed, the second connecting piece 53 is compressed to align the connecting slot with one end of the polishing roller 51, and the other end of the polishing roller 51 is inserted into the first connecting piece 52. Finally, the second connecting piece 53 is released to return to its original position around one end of the polishing roller 51, and the polishing roller 51 is rotated by the rotation of the motor 54 transmitted by the second connecting piece 53. When the polishing roller 51 contacts the top surface of the metal plate, the polishing effect is achieved;

[0057] As shown in Figure 5 and Figure 6 , the first connecting piece 52 and the second connecting piece 53 each include a connecting seat 55, and the connecting seat 55 of the first connecting piece 52 is rotatably connected with the sliding sleeve of one of the sliding guides 10. The machine shell 58 is fixed with the sliding sleeve of the other sliding guide 10;

[0058] The second connecting piece 53 further includes a mounting plate 56 and at least two compression pieces 57 (four are shown in the figure, including but not limited to this). The at least two compression pieces 57 are fixed between the mounting plate 56 and the connecting seat 55, and the length of the at least two compression pieces 57 is adjustable to adjust the distance between the mounting plate 56 and the connecting seat 55. The mounting plate 56 is fixed with the output shaft of the motor 54, i.e. the output shaft of the motor 54 is connected and fixed with the shaft hole on the mounting plate 56 by interference fit;

[0059] The at least two compression pieces 57 each include an extension rod 571 and a spring 572, and the extension rod 571 is fixed between the mounting plate 56 and the connecting seat 55, and the spring 572 is sleeved outside the extension rod 571;

[0060] The connecting seat 55 of the second connecting piece 53 is pressed towards the direction of the side mounting plate 56, which will compress the spring 572 between the connecting seat 55 and the mounting plate 56, and at the same time shorten the length of the telescopic rod 571. The telescopic rod 571 is a non-powered rod, which is composed of a larger size female rod and a male rod. When the length is shortened, the male rod is retracted into the female rod to shorten the length, so that the connecting seat 55 is close to the connecting seat 55. In this way, the connecting seat 55 will be detached from one end of the polishing roller 51. It should be noted that, as shown in Figure 6 the other end of the end of the polishing roller 51 also has a convex column, and the connecting seat 55 has a slot hole which is matched with the shape of the convex column, so that the convex column can be inserted and detached from the slot hole, and the slot hole can make the convex column bear the force to make the polishing roller 51 rotate as a whole.

[0061] As shown in Figure 7 the cleaning chamber 3 is located on one end of the conveyor 1 and covers the upper and lower parts of one end of the conveyor 1. Specifically, the cleaning chamber 3 is composed of a centralized box 31 fixed on the bottom of one side of the conveyor 1, and a shielding part 32 integrally connected to the top of the centralized box 31. The shielding part 32 is connected to a plurality of roller cylinders 33 which are rotatably connected to the front and rear sides of the shielding part 32 and are equidistantly arranged in a straight line inside the shielding part 32. The plurality of roller cylinders 33 are used to carry metal plates. The plates conveyed by the conveyor 1 will also move on the plurality of roller cylinders 33, that is, they will move on the roller cylinders 33 by the conveying thrust of the conveyor 1. One side of the conveyor belt carrying the plates will change direction after moving the plates onto the roller cylinders 33, and the transmission at the bottom of the shaft will change direction. In this way, the dust on the surface of the conveyor belt will fall into the centralized box 31 through the gap between the plurality of roller cylinders 33 when the direction is changed;

[0062] The cleaning structure includes a first brush strip 34 and a second brush strip 35. The first brush strip 34 is fixed in the shielding part 32. The dust on the surface of the plates moving on the roller cylinders 33 will be scraped by the first brush strip 34. After the plates move away from the roller cylinders 33, the dust scraped by the first brush strip 34 will also fall into the centralized box 31 through the gap between the plurality of roller cylinders 33.

[0063] The second brush strip 35 is fixed in the centralized box 31 close to one side of the conveyor 1. The second brush strip 35 is in contact with the surface of the conveyor belt at the bottom end of the conveyor 1 which changes direction, so as to further scrape the dust attached to the surface of the conveyor belt.

[0064] As shown in Figure 8The bottom of the collecting box 31 is shown as a slope, which makes the dust entering the interior slide along the slope and concentrate at the lowest part of the slope. A discharge port 36 is formed at the lowest part of the bottom slope of the collecting box 31. A baffle 37 is slidably arranged on the discharge port 36. The baffle 37 is pulled to open the discharge port 36. The dust concentrated at the lowest part of the slope is quickly discharged from the discharge port 36. The baffle 37 is specifically arranged. Two grooves are fixed on both sides of the discharge port 36 to accommodate the baffle 37 to slide up and down. The top of the baffle 37 is integrally connected with a baffle edge bent by 90 degrees to one side. The baffle edge is arranged on the top between the two grooves to prevent the baffle 37 from being pulled out of the two grooves and provide a force receiving part for pulling the baffle 37. Thus, the baffle 37 is located between the two grooves and blocks the discharge port 36 on one side under the action of gravity.
