[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Specific implementation examples are given below.

[0022] Please see Figure 1 - Figure 3 This utility model provides a technical solution: a protective device for the edge coating of ultra-thin foil current collectors, including a base 1, a column 2 fixedly connected to the top of the base 1, a protective structure 3 movably installed on the outside of the column 2, and an adjusting structure 4 movably installed on the outside of the protective structure 3. The protective structure 3 includes three fixing sleeves 31 sleeved on the outer wall of the column 2. A retaining sleeve 32 is fixedly connected to one side of the uppermost fixing sleeve 31 and one side of the lowermost fixing sleeve 31. A liquid storage bottle 33 is sleeved on the inner wall of the upper retaining sleeve 32. A sponge 35 is fixedly connected to the bottom of the liquid storage bottle 33. 3. An externally fixed regulating valve 34 is connected to the bottom. A special coating material is added to the liquid storage bottle 33. The regulating valve 34 is opened, causing the special coating material to fill the entire sponge 35. When the cut edge of the current collector ultrathin foil is squeezed and scraped through the middle of the sponge 35, a special protective layer can be coated on the cut edge surface of the current collector ultrathin foil under the action of the sponge 35. This improves the anti-friction and anti-corrosion capabilities of the cut edge of the current collector ultrathin foil, making the protection of the current collector ultrathin foil more automated and reliable, thereby improving the working effect and quality of the protection of the cut edge of the current collector ultrathin foil.

[0023] like Figure 2 As shown, the inner ring of the lower sleeve 32 is fitted with a funnel 36. The top opening of the funnel 36 is much larger than the diameter of the sponge 35. When the sponge 35 is squeezed, the excess special coating material squeezed out will fall into the funnel 36, thus avoiding the problem of waste of special coating material. At the same time, the funnel 36, with an opening much larger than the size of the sponge 35, can ensure the recycling effect of special coating material.

[0024] As Figure 2 shown, the bottom of the funnel 36 is fixedly connected with the backflow pipe 37, the top end of the base 1 is fixedly connected with the liquid pump 38, the input end of the liquid pump 38 is fixedly connected with the bottom end of the backflow pipe 37, the output end of the liquid pump 38 is fixedly connected with the circulating pipe 39, and the top end of the circulating pipe 39 is fixedly connected with the docking sleeve 310. The inner wall of the docking sleeve 310 is clamped on the top end of the liquid storage bottle 33. The special coating material flowing through the funnel 36 and the backflow pipe 37 to the liquid pump 38 can be pumped back into the liquid storage bottle 33 through the circulating pipe 39 under the action of the liquid pump 38, thereby improving the utilization rate of the special coating material, prolonging the overall working time of the protection device, and reducing the working frequency of maintaining and adding the special coating material.

[0025] As Figure 1 shown, the side of the middle position fixed sleeve 31 is fixedly connected with the limiting sleeve 311, the limiting sleeve 311 is made of elastic plastic material, and the inner wall of the limiting sleeve 311 is clamped on the outer wall of the circulating pipe 39. The limiting sleeve 311 can limit the circulating pipe 39, avoid the liquid pump 38 from shaking the circulating pipe 39 during operation, and thereby affect the overall stability of the coating protection device.

[0026] As Figure 3 shown, the adjusting structure 4 includes a threaded rod 41 screwed on one side of the fixed sleeve 31, an operating block 42 fixedly connected to the side of the threaded rod 41 away from the fixed sleeve 31, an extrusion block 43 fixedly connected to one end of the threaded rod 41 inside the fixed sleeve 31, and a receiving groove 45 formed in the inside of the fixed sleeve 31. The size and shape of the inner wall of the receiving groove 45 are matched with the size and shape of the outer wall of the extrusion block 43. Rotating the operating block 42 drives the threaded rod 41 to rotate, and thereby drives the extrusion block 43 to extrude the stand column 2, and thereby fixes the fixed sleeve 31. Conversely, the position of the fixed sleeve 31 on the stand column 2 can be adjusted, the sponge 35 is positioned, and the practical effect of the device is improved.

[0027] As Figure 3 shown, the end of the extrusion block 43 away from the threaded rod 41 is fixedly connected with a rubber pad 44, and the side of the rubber pad 44 away from the extrusion block 43 is an arc surface. When the fixed sleeve 31 is fixed, the rubber pad 44 can improve the fixing effect and avoid wear between the threaded rod 41 and the stand column 2. The arc surface of the rubber pad 44 can increase the contact area between the rubber pad 44 and the stand column 2, and thereby further improve the fixing effect.

[0028] As Figure 3 shown, the outer wall of the extrusion block 43 is fixedly connected with a sliding block 47, the inner wall of the receiving groove 45 is provided with a sliding groove 46, and the outer wall of the sliding block 47 is slidingly connected with the inner wall of the sliding groove 46. The cooperation between the sliding groove 46 and the sliding block 47 can ensure that the arc surface of the rubber pad 44 corresponds to the arc surface of the stand column 2, avoid misalignment between the rubber pad 44 and the stand column 2, and thereby prevent the fixing effect from being reduced.

[0029] The working principle of the utility model is: when using, first install base 1 in the side of the flow line of the current collector ultra-thin foil cutting edge, add special coating material in the liquid storage bottle 33, open the regulating valve 34, and then make the special coating material fill the whole sponge 35, when the cutting edge of the current collector ultra-thin foil extrudes and passes the middle part of the sponge 35, under the action of the sponge 35, a layer of special protective layer can be coated on the surface of the cutting edge of the current collector ultra-thin foil, and then the anti-friction and anti-corrosion ability of the cutting edge of the current collector ultra-thin foil is improved, the protection of the current collector ultra-thin foil is more automatic and more reliable, and then the working effect and working quality of the cutting edge protection of the current collector ultra-thin foil are improved, the excess special coating material extruded after the sponge 35 is extruded can fall in the hopper 36, and then the problem of waste of the special coating material is avoided, the hopper 36 with the opening much larger than the size of the sponge 35 can ensure the recycling effect of the special coating material, the special coating material flowing to the liquid pump 38 through the hopper 36 and the return pipe 37 can be pumped into the liquid storage bottle 33 through the circulating pipe 39 under the action of the liquid pump 38, and then the utilization rate of the special coating material is improved, the overall working time of the protection device is improved, and the working frequency of maintenance and oiling is improved, the limiting sleeve 311 can limit the circulating pipe 39, avoid the liquid pump 38 from driving the circulating pipe 39 to shake in the working process, and then affect the overall stability of the coating protection device, when assembling the cutting edge coating protection device of the current collector ultra-thin foil, the sliding fixing sleeve 31 can sleeve the position of each component of the protection structure 3, and then the sponge 35 can be more fitted to the metal foil cutting edge, the rotating operation block 42 is rotated, and then the threaded rod 41 is rotated, and then the extrusion block 43 can extrude the stand column 2, and then the fixing sleeve 31 can be fixed, and vice versa, the position of the fixing sleeve 31 on the stand column 2 can be adjusted, and then the sponge 35 is positioned, and the practical effect of the device is improved, when fixing the fixing sleeve 31, the rubber pad 44 can improve the fixing effect, avoid the abrasion between the threaded rod 41 and the stand column 2, the arc surface of the rubber pad 44 can improve the contact area between the rubber pad 44 and the stand column 2, and then the fixing effect is further improved, the cooperation between the sliding groove 46 and the sliding block 47 can ensure that the arc surface of the rubber pad 44 corresponds to the arc surface of the stand column 2, avoid the dislocation between the rubber pad 44 and the stand column 2, and then the problem of the decreased fixing effect is avoided.
