[0002] In the metal processing, wood processing, and other material manufacturing industries, sheet sanding is an essential process that directly affects the surface quality and subsequent processing performance of the product.
[0003] Existing technologies commonly employ large-scale automated grinding machines with conveyor belts or fixed workstations. These machines typically fix the sheet material on a conveyor platform and grind it using fixed or movable grinding heads. While offering a high degree of automation and efficiency, they also have significant limitations: such equipment can only grind one side of the sheet material. When grinding the other side is required, the sheet material must be flipped over and placed back onto the conveyor platform, resulting in low grinding efficiency. Utility Model Content

[0013] Furthermore, the polishing assembly includes a mounting bracket disposed on the movable frame, a baffle plate rotatably connected to the mounting bracket, a first roller brush disposed on the baffle plate, and a first driving member for driving the first roller brush to move.
[0014] Furthermore, the grinding assembly also includes two sets of side grinding units disposed on the movable frame for grinding the side of the sheet metal. Each side grinding unit includes a second drive member, a first mounting seat disposed on the output shaft of the second drive member, and a second roller brush disposed on the first mounting seat.
[0015] Furthermore, the grinding assembly also includes a clamping unit for pressing the sheet metal. The clamping unit includes a third driving member disposed on the movable frame, a second mounting base fixedly connected to the output shaft of the third driving member, and a positioning wheel rotatably connected to the second mounting base.
[0016] Furthermore, a limiting groove is provided on the gripper, so that when the plate is being ground, one side of the plate is located in the limiting groove.
[0017] Furthermore, the gripper is provided with a positioning element, which is inclined relative to the gripper.
[0018] Furthermore, the material rack includes a frame, several legs for supporting the frame, at least two material placement plates on the frame, and several guide rods on the material rack; the movable frame is slidably connected to the guide rods, and several grooves are formed on the material placement plates, with the two sides of the material respectively located in the grooves of two of the material placement plates.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0031] A mobile grinding machine includes: a material rack 10 and a mobile grinding mechanism 20;
[0032] Among them, the material rack 10 is used to place the sheet material 30, and the movable grinding mechanism 20 can move on the material rack 10 to grind the sheet material 30 on the material rack 10;
[0033] like Figures 1-3 As shown, the material rack 10 includes a frame 12, a plurality of support legs 11 for supporting the frame 12, at least two material placement plates 13 provided on the frame 12, and a plurality of guide rods 14 provided on the material rack 10.
[0034] Specifically, the support legs 11 are fixedly connected to the lower side of the frame 12. The frame 12 and the support legs 11 constitute the frame of the material rack 10. The number of support legs 11 can be set according to the work scenario, and the purpose is to support the frame 12. In this embodiment, four material racks 13 are fixedly connected to the frame 12, distributed in pairs at the front and rear positions of the upper part of the frame 12. The plate 30 is used to place between the two material racks 13. In this embodiment, two guide rods 14 are provided. The two guide rods 14 are fixedly connected to the front and rear sides of the frame 12 respectively. The front and rear sides of the movable frame in the movable grinding mechanism 20 are slidably connected to the two guide rods 14 respectively, so that the movable grinding mechanism 20 can move on the frame 12. Several grooves 15 are opened on the material racks 13. The number of grooves 15 can be set according to the actual situation and is not limited here. The two sides of the plate 30 are respectively located in the grooves 15 of the two material racks 13. Thus, the plate 30 can be stably placed on the material racks 13 by the restriction of the grooves 15.
[0035] like Figures 4-6 As shown, the movable polishing mechanism 20 includes: a movable frame, a polishing component 24, and a lifting component 26;
[0036] The movable frame can move laterally on the material rack 10. Two sets of grinding components 24 are provided on the movable frame. The two sets of grinding components 24 are symmetrically arranged on the movable frame. A lifting component 26 is provided on the movable frame. The lifting component 26 is used to lift the plate 30 on the material rack 10, so that the plate 30 is ground by the grinding component 24.
[0037] like Figure 5As shown, the polishing assembly 24 includes a mounting bracket 241 disposed on a movable frame, a baffle plate 244 rotatably connected to the mounting bracket 241, a first roller brush 245 disposed on the baffle plate 244, and a first drive member for driving the first roller brush 245 to move.
[0038] Specifically, the mounting frame 241 is fixedly connected to the frame 21 of the movable frame. Two bearing seats 242 are fixedly connected to the front and rear sides of the mounting frame 241, respectively. A rotating shaft 243 is fixedly connected to the baffle plate 244, with both ends of the rotating shaft 243 located inside the two bearing seats 242, thereby enabling the baffle plate 244 to rotate on the mounting frame 241. A first roller brush 245 is rotatably connected to the inner side of the mounting frame 241. By setting the first roller brush 245 on the inner side of the mounting frame 241, when the first roller brush 245 grinds the sheet metal 30, it can improve the grinding performance. To block impurities and prevent them from splashing, the first roller brush 245 is an electric roller brush in this embodiment. Since electric roller brushes are existing technology, they will not be described in detail here. The first driving component is a first cylinder 246 in this embodiment. In other embodiments, it can be a hydraulic cylinder, electric push rod, etc. It can be understood that the fixed end of the first driving component is hinged to the mounting bracket 241, and the output end of the first driving component is hinged to the baffle plate 244. Thus, by activating the first driving component, its output end is extended, which drives the baffle frame to swing, thereby making the first roller brush 245 fit with the plate 30.
[0039] like Figure 6 As shown, the sanding assembly 24 also includes two sets of side sanding units for sanding the sides of the sheet metal 30, which are arranged on the movable frame. The side sanding unit includes a second drive member, a first mounting base 248 arranged on the output shaft of the second drive member, and a second roller brush 249 arranged on the first mounting base 248.
[0040] Specifically, in this embodiment, the second driving component is a second cylinder 247. In other embodiments, it can be a hydraulic cylinder, an electric actuator, etc. The fixed end of the second driving component is fixedly connected to the frame 21 of the moving frame, and a first mounting base 248 is fixedly connected to its output end. A second roller brush 249 is rotatably connected to the first mounting base 248. In this embodiment, the second roller brush 249 is also an electric roller brush. When the second driving component is activated, the second roller brush 249 contacts the side of the sheet 30, thereby achieving the grinding of the side of the sheet 30.
[0041] like Figure 6 As shown, the grinding assembly 24 also includes a clamping unit for pressing the sheet metal 30. The clamping unit includes a third drive member disposed on the moving frame, a second mounting base 2411 fixedly connected to the output shaft of the third drive member, and a positioning wheel 2412 rotatably connected to the second mounting base 2411.
[0042] Specifically, in this embodiment, the third driving component is a third cylinder 2410. In other embodiments, it can be a hydraulic cylinder, an electric actuator, etc. The fixed end of the third driving component is fixedly connected to the frame 21 of the moving frame, and a second mounting base 2411 is fixedly connected to its output end. A positioning wheel 2412 is rotatably connected to the second mounting base 2411. The clamping unit is located in the middle of the two side grinding units. By activating the third driving component, the positioning wheel 2412 in the clamping unit of the two grinding components 24 will clamp the plate 30, thereby making it difficult for the plate 30 to move during the lifting process.
[0043] like Figure 4 As shown, the lifting assembly 26 includes a gantry 25 mounted on a movable frame, and two sets of lifting units slidably connected on both sides of the gantry 25; the lifting unit includes a sliding frame 261 slidably connected on the gantry 25, a gripper 262 mounted on the sliding frame 261, and a drive module for driving the sliding frame 261 to slide on the gantry 25.
[0044] Specifically, the gantry 25 is fixedly connected to the frame 21 of the movable frame; two sets of lifting units are used to lift the two sides of the sheet metal 30 upwards respectively; the sliding frame 261 can move up and down along the gantry 25, and the gripper 262 is fixedly connected to the sliding frame 261, which is used to lift the sheet metal 30 upwards. In this embodiment, the drive module includes a lifting motor 265 fixedly connected to the sliding frame 261, a rack 266 fixedly connected to the gantry 25, and a gear fixedly connected to the output shaft of the lifting motor 265. The gear meshes with the rack 266, thereby starting the lifting... Motor 265 causes the output shaft of the lifting motor 265 to rotate forward or reverse. Through the engagement of gear and rack 266, it drives the sliding frame 261 to move up and down. In other embodiments, the drive module can be composed of a motor, a screw, and a threaded seat. That is, the motor is fixedly connected to the moving frame or gantry 25, the end of the screw is fixedly connected to the output shaft of the motor, and the other end can be rotatably connected to the upper part of the gantry 25. The threaded seat is fixedly connected to the sliding frame 261, and the threaded seat is threadedly connected to the screw. When the motor is started, the sliding frame 261 moves up and down through the engagement of the screw and the threaded seat.
[0045] like Figure 5 As shown, a limiting groove 264 is provided on the gripper 262, and when the plate 30 is being ground, one side of the plate 30 is located in the limiting groove 264.
[0046] Specifically, the gripper 262 is L-shaped, with its upper part fixedly connected to the sliding frame 261, and a limiting groove 264 is provided on the upper surface of the lower extension end. When the gripper 262 lifts the sheet 30 upward, since the sheet 30 is T-shaped, the end side of the sheet 30 is located in the limiting groove 264, making it difficult for the sheet 30 to slip off the gripper 262.
[0047] like Figure 5 As shown, a positioning element 263 is provided on the gripper 262, and the positioning element 263 is inclined relative to the gripper 262;
[0048] Specifically, the positioning component 263 is an inclined plate, which is fixedly connected to the corner of the gripper 262. When the sheet metal 30 is in an offset state on the placement plate 13, the gripper 262 moves to the lower side of both ends of the sheet metal 30. At this time, the gripper 262 moves upward, which drives the positioning component 263 to move upward. Since the sheet metal 30 is in an offset state on the placement plate 13, and the positioning component 263 is in an inclined state, it will push the sheet metal 30 to the center, so that the sheet metal 30 is in the corresponding position, thus avoiding affecting the subsequent grinding.
[0049] like Figure 4 As shown, the mobile frame includes a frame 21, at least one movable wheel 22 rotatably connected to the frame 21, and a drive motor 23 disposed on the frame 21. The output shaft of the drive motor 23 is connected to the movable wheel 22 to drive the movable wheel 22 to rotate.
[0050] The front and rear sides of the frame 21 are slidably connected to two guide rods 14 respectively. The front and rear sides of the frame 21 are respectively provided with two moving wheels 22 and two drive motors 23. The output shaft of the drive motor 23 is connected to the moving wheels 22 to drive the moving wheels 22 to rotate. The moving wheels 22 can drive the frame 21 to move on the frame 12. The drive motor 23 is preferably a geared motor.
[0051] A mobile grinder is used in the following ways:
[0052] First, the worker can stop the movable grinding mechanism 20 in the middle of the frame 12. Then, the plates 30 to be ground are placed sequentially onto the placement plate 13. The grooves 15 on the placement plate 13 can separate the plates 30 and prevent them from slipping off. Next, the operator can move the movable grinding mechanism 20 to the rightmost or leftmost end of the frame 12. Taking the rightmost end as an example, when the movable grinding mechanism 20 is located at the rightmost end of the frame 12, the gripper 262 is initially positioned below. At the extreme position on the side, with the gripper 262 positioned below the upper sides of the sheet metal 30, the worker can activate the drive module. The drive module moves the sliding frame 261 upward, which in turn moves the gripper 262 upward, and the gripper 262 moves the sheet metal 30 upward. When the gripper 262 passes through the grinding assembly 24, the worker can activate the first cylinder 246, the second cylinder 247, and the third cylinder 2410. Of course, the first cylinder 246, the second cylinder 247, and the third cylinder 2410... Cylinders 247 and 2410 can also be started via sensors. The sensor arrangement is existing technology and will not be elaborated here. When cylinders 246, 247, and 2410 are started, the first roller brush 245, the second roller brush 249, and the positioning wheel 2412 will come into contact with the sheet metal 30. The first roller brush 245 will polish the entire sheet metal 30, the second roller brush 249 will polish the sides of the sheet metal 30, and the positioning wheel 2412 will clamp the sheet metal 30, avoiding... To prevent the sheet metal 30 from moving during grinding; after grinding the sheet metal 30 is completed, the first cylinder 246, the second cylinder 247 and the third cylinder 2410 are reset, so that the first roller brush 245, the second roller brush 249 and the positioning wheel 2412 are no longer in contact with the sheet metal 30. Then, the lifting component 26 drives the sheet metal 30 to move downward and put the sheet metal 30 back on the placement plate 13. Then, the moving grinding mechanism 20 moves to the next station to grind the sheet metal 30.
