[0033] As a technical optimization solution of the present utility model, by providing the installation groove 11, the first spring 12, the convex plate 13 and the limiting groove 14, the installation groove 11 can limit the first spring 12, and the collection box 6 can be movably limited by using the convex plate 13 and the limiting groove 14, thereby improving the stability of the collection box 6. At the same time, since the front side and the rear side of the top of the convex plate 13 and the front side and the rear side of the inner wall of the limiting groove 14 are all chamfered, it is convenient for the collection box 6 to move back and forth.

[0034] Reference Figure 3 , moving grooves 15 are provided inside both the first driving roller 71 and the second driving roller 72. A second spring 16 is movably connected to the surface of the insertion rod 85. A limiting ring 17 is fixedly connected to the surface of the insertion rod 85. One end of the second spring 16 close to the limiting ring 17 is fixedly connected to the inner side of the limiting ring 17.

[0036] Reference Figure 3 , a first through groove 18 is provided on the left side of the surface of the first driving roller 71 and on the right side of the surface of the second driving roller 72. A second through groove 19 is provided on the front side of the surface of the connecting column 83. The first through groove 18 is communicated with the second through groove 19. A pull rod 20 is fixedly connected to the front side of the surface of the insertion rod 85.

[0037] As a technical optimization solution of the present utility model, by providing a first through groove 18, a second through groove 19 and a pull rod 20, the first through groove 18 and the second through groove 19 facilitate the movement of the pull rod 20, and by pulling the pull rod 20, the plug rod 85 can be driven to move left and right.

[0038] Working principle and usage process of the present utility model: During use, the metal profile to be polished is placed on the top of the conveyor 1, and the conveyor 1 and the polishing equipment main body 4 are started simultaneously. When the metal profile passes through the bottom of the polishing equipment main body 4, the polishing equipment main body 4 can polish the oxide scale on it, and the polished oxide scale will adhere to the surface of the conveyor 1. At this time, the user can start the servo motor 81 to drive the connecting column 83 connected to the first driving roller 71 to rotate by the output end of the servo motor 81. The part of the connecting column in contact with the first driving roller 71 and the second driving roller 72 is closely attached. At the same time, a rubber sleeve is sleeved on the surface of the part of the plug rod 85 penetrating the inside of the connecting column 83. Therefore, when the connecting column 83 rotates, it can drive the first driving roller 71 and the second driving roller 72 to rotate in sequence. The rotation of the first driving roller 71 and the second driving roller 72 can drive the connecting ring 73 and the cleaning brush 74 to rotate. Since the cleaning brush 74 is in contact with the surface of the conveyor 1, when the cleaning brush 74 rotates, it can clean the surface of the conveyor 1, and the oxide scale falling off during cleaning can enter the inside of the collection box 6, thus facilitating the user to collect and clean. When it is necessary to replace the cleaning brush 74, first pull the pull rod 20 to drive the plug rod 85 to be pulled in the direction close to the movable groove 15. At this time, the limiting ring 17 moves inward to drive the second spring 16 to contract. When the plug rod 85 is separated from the inside of the connecting column 83, the user can remove the first driving roller 71 and the second driving roller 72 from the inside of the connecting column 83. Then, by separately pulling the first driving roller 71 and the second driving roller 72, the cross plate 9 can be separated from the inside of the cross groove 10. At this time, the user can remove the connecting ring 73 sleeved on the surfaces of the first driving roller 71 and the second driving roller 72 for replacement or cleaning.

[0039] To sum up: For this polishing device for removing oxide scale from the surface of metal profiles, by providing the support plate 5 and the collection box 6, the support plate 5 can support the collection box 6, and the collection box 6 is used to collect the oxide scale falling from the surface of the conveyor 1, which solves the problem that since the oxide scale falling during the grinding and polishing of metal profiles will fall on the surface of the conveyor belt, and this device does not have a collection structure. Therefore, when the conveyor belt with attached oxide scale moves to the bottom of the conveyor, it will fall to the ground and cause pollution to the workshop, and the oxide scale scattered on the ground is small in volume, making it troublesome for the user to clean.
