[0054] Specific, the traction and compression roller is provided with paraffin, which is convenient to wipe the dust on the roller, and the drying device 10 effectively dries the paint.

[0055] Working principle:

[0056] The coating material 100 is taken out from the first winding shaft 21 in the feeding mechanism 2, passes through the tension rod 5, is placed under the scraper 62, passes through the drying device 10, and is finally wound on the material collecting mechanism 3. Then the first driving motor 20 is turned on, so that the feeding mechanism 2 and the material collecting mechanism 3 work at the same time. At this time, the third driving motor 42 is turned on, so that the third driving motor 42 works. When the third driving motor 42 works, the third driving motor 42 drives the stirring shaft 43 to rotate. At this time, the stirring shaft 43 stirs the material in the storage barrel 40. Then the pump 41 is turned on, so that the pump 41 sends the material in the storage barrel 40 to the feeding box 7 through the conveying pipe 45. Since the adjusting plate 71 and the feeding box 7 are both provided with the adjusting hole 75, the paint in the feeding box 7 falls onto the coating material 100 through the adjusting hole 75 at this time. With the cooperation of the feeding mechanism 2 and the material collecting mechanism 3, the scraper 62 uniformly applies the paint on the coating material 100, and then the drying device 10 dries it.

[0057] The cooperation of the feeding mechanism 4 and the feeding box 7 in the equipment makes the paint be stirred during use, avoiding the situation that the paint sinks to the bottom during use, thereby affecting the application of the paint, and avoiding the situation that the paint is not sticky enough due to sedimentation, thereby affecting the coating of the product.

[0058] When the device is coated, the material is coated too thick or too thin, at this time the rotating handle can be rotated, the rotating handle 65 drives the threaded rod 61 to rotate, when the threaded rod 61 rotates, the threaded rod 61 moves on the connecting plate 60, at this time the scraper 62 is close to or away from the support table 6, when the scraper 62 is away from the support table 6, the scraper 62 moves up, when the scraper 62 moves up, the moving frame installed on the scraper 62 moves up, when the moving frame 76 moves up, the wedge-shaped block 74 on the moving frame 76 continuously extrudes the extrusion block 73, so that the extrusion block 73 extrudes the sliding rod 72, when the sliding rod 72 is extruded, the sliding rod 72 pushes the adjusting plate 71 to slide in the feeding box 7, at this time the second spring 70 is compressed, and the gap between the adjusting hole 75 on the adjusting plate 71 and the adjusting hole 75 on the feeding box 7 becomes larger, at this time the discharging speed of the feeding box 7 becomes faster and more, and when the scraper 62 moves down, the effect is opposite, at this time the gap between the two adjusting holes 75 becomes smaller, and the discharging speed of the feeding box 7 becomes smaller and less;

[0059] The cooperation of the threaded rod 61, the scraper 62, the moving frame 76, the wedge-shaped block 74, the second spring 70 and the adjusting plate 71 in the device makes the gap between the scraper 62 and the coating material 100 larger when the scraper 62 is away from the support table 6, so that the coating on the coating material 100 becomes thicker, the adjusting hole 75 becomes larger, and the coating can be transported to the coating material 100 faster and more, avoiding uneven coating caused by insufficient material, and when the scraper 62 moves down to be close to the coating material 100, the thickness of the coating on the coating material 100 becomes thinner, the adjusting hole 75 becomes smaller, and the coating transportation becomes less, thereby avoiding the waste of coating caused by the fact that the coating cannot be completely coated due to excessive coating transportation.

[0060] In summary, the embodiment of the application provides a coating line for pole piece, which comprises a workbench, a feeding mechanism and a collecting mechanism for collecting and releasing coating material are arranged on the workbench at intervals, a coating mechanism is arranged between the feeding mechanism and the collecting mechanism, the coating mechanism comprises a scraper assembly and a feeding box assembly, the feeding box assembly is connected with the feeding mechanism, and the feeding mechanism is used for feeding the feeding box assembly. Through the cooperation of the feeding mechanism and the feeding box in the device, the coating can be stirred during use, so that the coating is not deposited at the bottom during use, thereby affecting the coating of the coating, and the adhesion of the coating is affected due to the deposition, thereby affecting the coating of the product.
