Technical Field

[0001] The utility model relates to the technical field of lithium battery diaphragm production equipment, in particular to a cooling device for a lithium battery diaphragm production line. Background Art

[0002] The main function of lithium battery separator is to separate the positive and negative electrode materials of the battery to prevent the two poles from contacting and short-circuiting, while also allowing electrolyte ions to pass through it. In the production line of lithium battery separator, the film needs to be coated. After coating, the separator and the coating need to be cured, and then cooled and cleaned before being rolled up;

[0003] In the subsequent cooling process, the usual cooling method is to cool the diaphragm by spraying. During the transmission of the diaphragm on the production line, a lot of impurities will adhere to the surface. In order to reduce the waste of resources in the cooling device, the cooling water needs to be recycled. However, there is no cleaning component on the cooling device to treat its surface, which causes subsequent impurities to circulate with the cooling water, causing equipment blockage and affecting the service life of the cooling device.

A vertically arranged connecting plate 21 is provided at the end of the interior of the processing box 2 away from the cooling box 1. A rectangular mounting frame 22 is fixedly provided at the bottom of the connecting plate 21. The mounting frame 22 Cleaning brushes 23 are fixedly provided on the upper and lower sides of the inner wall.

Two symmetrically arranged vertical plates 24 are fixedly provided on the upper surface of the connecting plate 21. Push rods 251 are fixedly provided on the opposite side of the two vertical plates 24. A horizontally arranged movable plate 25 is fixedly provided between the two push rods 251. A rectangular groove 26 is provided through the movable plate 25. An arc groove 27 is provided at the diagonal point of the rectangular groove 26. A Y-shaped rotating block 28 is rotatably provided at the middle end of the rectangular groove 26. A rotating rod 29 is fixedly provided at the middle end of the rotating block 28. The top of the rotating rod 29 is rotatably provided in the processing box 2. An air pump 3 is fixedly installed on the upper and lower surfaces of the outer walls of the processing box 2. The output end of the air pump 3 is connected to the processing box 2 and is fixed with a suction nozzle.

[0019] A motor 291 is fixedly installed on the outer wall of the processing box 2 near the rotating rod 29. The output end of the motor 291 is coaxially fixed on the rotating rod 29. The set motor 291 can facilitate the staff to control the rotation of the rotating rod 29, making it easier for the staff to operate.

[0020] Support rods 211 are fixed at both ends of the connecting plate 21. Both ends of the support rods 211 pass through the processing box 2. The support rods 211 can movably pass through the processing box 2, thereby supporting the structure on the connecting plate 21 so that it can work stably.

[0021] Two symmetrically arranged fixed plates 4 are fixed on one end of the outer wall of the cooling box 1 away from the processing box 2, a first transverse plate 41 is fixed below the two fixed plates 4, and a second transverse plate 42 is arranged oppositely above the first transverse plate 41. Cotton plates 43 are installed on the opposite sides of the first transverse plate 41 and the second transverse plate 42. The cotton plates 43 can absorb the cooling water on the surface of the diaphragm to make the surface of the diaphragm clean, which is convenient for subsequent winding; a long plate 47 is fixed on the top of the two fixed plates 4, and a vertically arranged screw rod 44 is threaded at the middle end of the long plate 47. The bottom of the screw rod 44 is rotatably arranged on the second transverse plate 42, and the screw rod 44 can push the second transverse plate 42 when it rotates. The horizontal plate 42 moves, thereby controlling the second horizontal plate 42 to move toward the first horizontal plate 41 to control the distance between the two, so that the cotton board 43 arranged between the first horizontal plate 41 and the second horizontal plate 42 can clean the cleaning water attached to the surface of the partition passing through; vertically arranged vertical rods 45 are movably inserted at both ends of the long plate 47, and the bottom of the vertical rods 45 is fixed on the second horizontal plate 42. The arranged vertical rods 45 can support the up and down movement of the second horizontal plate 42, so that the second horizontal plate 42 can move stably; two symmetrically arranged conveying rollers 5 are provided between the processing box 2 and the two fixed plates 4 on the side away from the cooling box 1, and the arranged conveying rollers 5 can provide power and limit for the conveying of the diaphragm.

[0022] The spray plate 11 is connected to the bottom of the cooling box 1 through a return pipe 14. The return pipe 14 can input cooling water from the bottom into the spray plate 11 through a water pump to perform cooling and spraying operations on the diaphragm.

[0023] Working principle: When in use, the diaphragm enters the cooling box 1 through the conveying roller 5, passes under the limiting roller 12, and then moves out from the conveying roller 5 on the other side. During this process, in the processing box 2, the motor 291 will directly drive the rotating rod 29 to rotate. At this time, the rotating rod 29 will drive the rotating block 28 to rotate. At this time, one end of the rotating block 28 will be against the side wall of the rectangular groove 26. At this time, the rotating block 28 will push the movable plate 25 to move toward one end. The end of the rotating block 28 will rotate in the arc groove 27. At this time, the other end of the rotating block 28 will be against the other side of the rectangular groove 26. At this time, the movable plate 25 will move in the opposite direction. Movement, under such repeated rotation of the rotating rod 29, the movable plate 25 can be driven to move repeatedly, so that the movable plate 25 pushes the vertical plate 24 through the push rod 251, driving the connecting plate 21 and the mounting frame 22 below to move repeatedly. At this time, the cleaning brush 23 provided on the inner wall of the mounting frame 22 will process the impurities on the diaphragm. The repeatedly moving cleaning brush 23 will fully clean the surface of the diaphragm. Subsequently, the dust on the surface of the diaphragm will be sucked out by the vacuum pump 3 and the air nozzle to prevent impurities from entering the cooling water during the subsequent cooling process, causing blockage in the cooling device during the subsequent circulation and shortening the service life.

[0024] The spray plate 11 can continuously spray cooling water toward the diaphragm below the limiting roller 12 to cool its surface. At the same time, cooling water will continuously accumulate at the bottom of the cooling box 1. The cooling water will flow back into the spray plate 11 through the return pipe 14 to perform a spray cooling operation. After the above operation, the entry of impurities can be avoided, which will affect the normal operation of the equipment in the subsequent circulation due to excessive impurities in the cooling water when cooling the diaphragm.

[0025] After cooling, the diaphragm will move between the first transverse plate 41 and the second transverse plate 42. The cotton plate 43 arranged between the first transverse plate 41 and the second transverse plate 42 can absorb the cooling water on the surface of the diaphragm to make the surface of the diaphragm clean, which is convenient for subsequent processing operations.

[0026] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
