DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] A sheet metal grinding device comprises a top plate 10, side plates 20 are fixed on both sides of the bottom of the top plate 10, a support block 21 is fixed on the bottom of the side plate 20, a roller 22 is rotatably provided on the side of the support block 21, the top plate 10 and the two side plates 20 are combined to form a U shape, and the roller 22 can be a roller commonly used in existing sheet metal grinding devices;

[0040] In the examples of this application, please refer to Figure 1Two support plates 30 located between the two side plates 20 are fixed at the bottom of the top plate 10, a motor 40 is fixed between the two support plates 30, the motor 40 is connected and controlled in an existing manner, the two support plates 30 are rotatably connected with a movable frame 50, specifically, the movable frame 50 is a special-shaped frame body, the cross section of the movable frame 50 is U-shaped, the movable frame 50 is composed of two side panels, a top connecting plate and a baffle, the two side panels are located on both sides of the two support plates 30, a roller 61 is arranged between the two side panels, and a grinding brush 62 is arranged on the outside of the roller 61, and the grinding brush 62 adopts an existing iron plate grinding A commonly used roller brush for the grinding roller can be used, such as a wire brush. The top connecting plate is fixed to the top between the two side panels and is located on the sides of the two support plates 30. The baffle is fixed between the two side panels. A tension spring 51 is arranged between the movable frame 50 and the top plate 10. The roller 61 is connected to the motor 40 through a transmission structure 70. When in use, the entire device is placed on the iron sheet to be processed, the roller 22 is placed on the iron sheet, and then the motor 40 is started to drive the roller 61 to rotate through the transmission structure 70, which can drive the grinding brush 62 to rotate. The grinding brush 62 continuously rotates on the iron sheet to complete the grinding and rust removal operation.

[0041] Furthermore, the transmission structure 70 includes two rotating shafts 71 rotatably connected to the movable frame 50, one of which is fixedly connected to the output shaft of the motor 40, and is rotatably connected to the movable frame 50 and the support plate 30, and is fixed with a driving wheel 74, the other rotating shaft 71 is fixedly connected to the support plate 30, and is rotatably connected to the movable frame 50, a bearing is provided at the connection between the rotating shaft 71 and the movable frame 50, both ends of the roller 61 are fixed with a rotatable fixed shaft 72 passing through the movable frame 50, one of which is fixedly connected to a driven wheel 73, and the driven wheel 73 is connected to the driving wheel 74 through a belt 75. When in use, starting the motor 40 can drive the rotating shaft 71 and the driving wheel 74 to rotate, thereby driving the belt 75 to rotate, thereby driving the driven wheel 73 to rotate, and finally driving the fixed shaft 72, the roller 61 and the grinding brush 62 to rotate. At the same time, through the setting of the rotating shaft 71, the movable frame 50 can rotate relative to the rotating shaft 71 and the support plate 30, so as to facilitate subsequent adjustment.

[0042] For further examples, see Figure 1 and 2A handrail 80 is fixed obliquely on the top of the top plate 10, and a pulling structure 90 is arranged between the movable frame 50 and the handrail 80. Specifically, the pulling structure 90 includes a handle 91 fixed to the end of the handrail 80, and a brake grip 92 is arranged at the handle 91. The brake grip 92 is connected to a steel wire rope 94. The brake grip 92 and the steel wire rope 94 connected thereto can refer to the brake handle of an existing bicycle. When the brake grip 92 is squeezed, the steel wire rope 94 can be pulled; the movable frame 50 is fixedly connected to a fixing rod 93, and the end of the fixing rod 93 is fixedly connected to the steel wire rope 94, and the steel wire rope 94 is in a taut state. A guide wheel 95 is rotatably arranged at the bottom of the top plate 10, and the steel wire rope 94 passes around the guide wheel 95 to reduce the wear of the steel wire rope 94;

[0043] When in use, the movable frame 50 can be continuously pulled by the tension spring 51 so that the grinding brush 62 is relatively upward. In the process of grinding the iron sheet, the brake handle 92 is squeezed to pull the wire rope 94, thereby pulling the fixed rod 93, and the movable frame 50 can be driven to rotate (this process will offset part of the tension of the tension spring 51), and then the grinding brush 62 can be driven to move, so that the grinding brush 62 can only stick to the iron sheet to ensure the quality of grinding. The strength of the grinding brush 62 sticking to the iron sheet can be adjusted by the pinching amplitude to control the grinding effect. The user only needs to pinch it, and no extra force is required. The operation is simple and more convenient for the user to operate, ensuring the grinding effect.
