DETAILED DESCRIPTION

[0022] 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.

[0023] See also Figure 1 A sodium ion battery pole piece grinder in this embodiment includes a workbench 1, a base 3 is fixed on all four sides of the lower surface of the workbench 1, a support frame 2 is fixed on the upper surface of the workbench 1, a grinding mechanism body 6 is provided on the workbench 1, a telescopic cylinder 4 is fixed on the inner top wall of the support frame 2, a fixing mechanism body 5 is provided on the telescopic cylinder 4, and a dustproof mechanism 7 is provided on the support frame 2.

[0024] It should be noted that the dustproof mechanism 7 ensures that the protective cover 708 and the workbench 1 are closely matched during grinding, ensuring stable and safe grinding of the sodium-ion battery electrode in a closed environment. At the same time, it can also effectively absorb dust, improve work efficiency and reduce maintenance costs.

[0025] See also Figures 1 to 3 In order to facilitate the device to effectively absorb dust and improve work efficiency, the dust-proof mechanism 7 in this embodiment includes a starting component, on which a moving component is provided. The dust-proof mechanism 7 also includes a dust suction component, and the starting component includes a driving motor 701 fixed to the right side of the support frame 2. The output shaft of the driving motor 701 is fixed with a driving rod 702 having one end penetrating into the interior of the support frame 2. A supporting plate is fixed to the right side of the top wall of the support frame 2. The right side of the supporting plate is rotatably connected to the left end of the driving rod 702 through a bearing, so that the driving rod 702 can rotate more smoothly. To increase stability, an adjustment hole rotatably connected to the driving rod 702 is opened on the right side of the support frame 2, and a first gear 703 is fixed to the outer surface of the driving rod 702. The front and rear sides of the first gear 703 are meshed with second gears 704, and the inner wall of the axis of the second gear 704 is fixed with two bidirectional screws 705 rotatably connected between the left and right sides of the inner cavity of the support frame 2 through bearings. The driving motor 701 is started to drive the driving rod 702 and the second gear 704 to rotate, thereby causing the bidirectional screw 705 to rotate, providing power for adjusting the position of the moving component.

[0026] Among them, the moving assembly includes a moving block 706 threadedly connected to the left and right sides of the outer surface of the bidirectional screw 705, the bottom of the moving block 706 is hinged with a connecting rod 707, and the bottoms of the left and right groups of connecting rods 707 are hinged with protective covers 708. Two guide grooves are provided on the left and right sides of the inner top wall of the support frame 2, and the inner walls of the guide grooves are slidably connected with guide blocks. The top of the moving block 706 is fixed to the bottom of the guide block, and the cross-sections of the guide grooves and the guide blocks are both convex. The movement of the connecting rod 707 is driven by the movement of the moving block 706 to ensure that the protective cover 708 can move stably until it covers and closes the entire grinding area. At the same time, the cooperation of the guide grooves and the guide blocks ensures the stability and accuracy of the movement of the protective cover 708.

[0027] At the same time, the dust collection assembly includes a mounting base fixed to the right side of the workbench 1, a fan 709 is fixed on the upper surface of the mounting base, a feed hose 710 is fixed to the air inlet of the fan 709, a discharge pipe 711 is fixed to the air outlet of the fan 709, an end of the discharge pipe 711 away from the fan 709 is fixed to the right side of the storage box 712, an end of the feed hose 710 away from the fan 709 is fixed to the right side of the protective cover 708, the fixing mechanism body 5 is located inside the protective cover 708, and the A movable hole is opened on the upper surface of the protective cover 708, and a sealing ring is fixed on the inner wall of the movable hole. The sealing ring fits with the outer surface of the telescopic cylinder 4. A box door is hinged on the front of the storage box 712. The upper surface of the storage box 712 is fixed to the lower surface of the workbench 1, so that the dust generated during the grinding process can be sucked into the storage box 712 by the fan 709 and transported to the storage box 712 through the feed hose 710 and the discharge pipe 711, which effectively reduces the impact of dust on the working environment and protects the cleanliness of the inside of the grinder.

[0028] It should be noted that during grinding, the dust-proof mechanism 7 can ensure that the sodium-ion battery electrode is grinded stably and safely in a closed environment, and can also further improve the dust removal effect and improve work efficiency.

[0029] The working principle of the above embodiment is:

[0030] (1) First, the telescopic cylinder 4 is started to drive the fixing mechanism body 5 to move toward the grinding mechanism body 6 until a suitable grinding distance is reached. At this time, the driving motor 701 is started to drive the driving rod 702 and the first gear 703 to rotate, and the two second gears 704 meshing therewith are driven to rotate, thereby driving the bidirectional screw 705 to rotate, so that the two moving blocks 706 move along the bidirectional screw 705. The movement of the moving block 706 simultaneously drives the guide block to move along the guide groove, ensuring that the movement of the moving block 706 is more stable, thereby enabling the connecting rod 707 and the protective cover 708 to move more stably, until the lower surface of the protective cover 708 is tightly fitted with the upper surface of the workbench 1, thereby achieving a comprehensive closure of the fixing mechanism body 5. This closure method ensures the stability and safety of the sodium ion battery electrode during the grinding process to a certain extent.

[0031] (2) In the closed state, the grinding mechanism body 6 can grind the sodium ion battery electrode on the fixing mechanism body 5 while turning on the fan 709 to suck the dust generated by grinding into the storage box 712 through the feed hose 710 and the discharge pipe 711. Through the operation of the dustproof mechanism 7, the device can more comprehensively enclose the fixing mechanism body 5 in the protective cover 708 during the grinding process, effectively improving the dust adsorption effect and reducing the difficulty of cleaning the dust, thereby improving the working efficiency of the device. This design not only ensures the safety of the grinding process, but also improves the working efficiency and reduces the maintenance cost.
