[0019] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0020] Refer to Figures 1-3 : A sheet grinding device, including a workbench 1. The workbench 1 is of a box structure. A powerful blower 3 communicating with its interior is installed on the right side wall of the workbench 1. A fixing plate 2 is installed on the top of the workbench 1. A blanking port 4 communicating with the interior of the workbench 1 is opened on the left side of the top of the fixing plate 2. A dust-proof box 5 covering the outside of the blanking port 4 is installed on the top of the fixing plate 2. Air intake nets 20 are installed on both the left and right sides of the top of the dust-proof box 5. A sealing cover is hinged to the bottom of the workbench 1 and can be rotated and opened. In the initial state, the sealing cover is in a horizontal state and fixed. The bottom of the workbench 1 is sealed. In this way, the debris generated by grinding can be collected into the workbench 1. The grinding work is carried out in the dust-proof box 5. The debris generated by grinding will pass through the blanking port 4 and enter the workbench 1. When the powerful blower 3 is started, the gas in the workbench 1 can be pumped out, creating a negative pressure environment in the workbench 1, which can suck the debris generated during the grinding process into the workbench 1. A filter screen 11 is installed on the right side wall of the workbench 1, and the filter screen 11 is located at the air inlet of the powerful blower 3. The setting of the filter screen 11 can prevent debris from entering the powerful blower 3, making the powerful blower 3 safer and avoiding damage to the powerful blower 3 by debris.

[0021] An electric push rod 6 is installed on the top of the dust-proof box 5. The top of the electric push rod 6 is fixedly connected to a fixing frame 7. Vertical plates 8 are installed on both the front and rear sides of the top of the fixing frame 7. A grinding motor 9 is fixedly connected to the front of the front vertical plate 8. The output shaft of the grinding motor 9 is fixedly connected to a grinding roller 10. When the electric push rod 6 expands and contracts, it can drive the fixing frame 7 and the vertical plate 8 to move up and down. When the vertical plate 8 moves up and down, it can drive the grinding motor 9 to move up and down synchronously. After the grinding motor 9 is started, it can drive the grinding roller 10 to rotate. The rotating grinding roller 10 can grind and process the sheet. When the electric push rod 6 expands and contracts to drive the vertical plate 8 to move up and down, it can drive the grinding motor 9 and the grinding roller 10 to move synchronously, thereby adjusting the height of the grinding roller 10 to make the height of the grinding roller 10 suitable for grinding and processing sheets of different thicknesses.

[0022] In another embodiment, strip-shaped holes 12 corresponding to the grinding rollers 10 are formed in the front and rear side walls of the dust-proof box 5, and through holes 13 are formed in the left and right side walls of the dust-proof box 5.

The plate can move the plate to the grinding position more labor-saving along the first rollers 14 and the second rollers 15. The plate needs to pass through the through hole 13 on the right side and enter below the grinding roller 10 for grinding work. After grinding is completed, the plate passes through the through hole 13 on the left side, so that the plate can be taken out more conveniently. The setting of the strip-shaped holes 12 facilitates the up and down movement of the grinding rollers 10.

[0023] In another embodiment, an installation groove 16 is formed at the top of the through hole 13. A vertical spring 17 is installed inside the installation groove 16. A lifting plate 18 fixedly connected to the bottom end of the vertical spring 17 is slidably connected inside the installation groove 16. A sealing plate 19 located inside the through hole 13 is fixedly connected to the bottom of the lifting plate 18. When the plate is inside the through hole 13, the plate upwardly presses the sealing plate 19 and the lifting plate 18, compressing the vertical spring 17, so that the sealing plate 19 can abut against the upper side of the plate, blocking the upper part of the through hole 13 and preventing dust from escaping from this position, ensuring the collection effect of the dust generated by grinding.

[0024] In summary, when the present utility model is in use, the plate moves from right to left. The plate can move the plate to the grinding position more labor-saving along the first rollers 14 and the second rollers 15. The plate needs to pass through the through hole 13 on the right side and enter below the grinding roller 10. After the grinding motor 9 is started, it can drive the grinding roller 10 to rotate. The rotating grinding roller 10 can grind the plate.
