Description

Technical Field

[0001] The utility model relates to the technical field of coating equipment, in particular to a fixed micro-concave coating scraper material box. Background Art

[0002] Lithium battery separator production line refers to a series of equipment and process flow used to produce lithium battery separators. The separator is an important component of lithium batteries. It can isolate the positive and negative electrodes to prevent short circuits, while allowing lithium ions to pass through to achieve battery charging and discharging. The quality and performance of the separator directly affect the safety, cycle life and energy density of lithium batteries. When coating lithium battery separators, separator coating machines are often required.

[0003] At present, the fine adjustment method for some fixed coating scraper material boxes is to use a screw to push directly, and the flipping device has no buffer. The screw adjustment accuracy is not fine enough, resulting in serious wear and tear of the coating roller and the scraper blade. The flipping mechanism has no buffer and it is easy for the parts to collide hard, causing the fixed rod to deform, thereby changing the horizontal position of the material box and affecting the coating effect.

[0029] A flip shaft 41 is rotatably provided on one side of the flip adjustment seat 4, a fixed rotating shaft 42 is provided on one side of the flip shaft 41 of the flip adjustment seat 4, and a buffer mechanism 43 is provided above the flip shaft 41, the buffer mechanism 43 includes a cylinder buffer 431, the cylinder buffer 431 is installed on the connecting plate 1, a plastic head screw top 432 is connected to the bottom output end of the cylinder buffer 431, the flipping material box makes the rotating shaft hit the plastic head screw top 432, the flip shaft locking cylinder 8 pushes the locking slider 9 and makes the locking slider 9 press the bearing of the flip shaft 41 to contact the limit block 14.

[0030] The fine adjustment mechanism 6 includes a driving assembly 61, a threaded rod 62 is assembled and connected to the output end of the driving assembly 61, a push head 63 is assembled and installed at the bottom of the threaded rod 62, and the inclined surface of the push head 63 can play a role in fine adjustment.

[0031] In addition, a cylinder 71 is provided at the rear end of the connecting wall panel fixing plate 7, and a piston rod assembled at the output end of the cylinder 71 is connected to the connecting plate 1. A connecting block 73 is provided at the front end of the connecting wall panel fixing plate 7. A ball bearing 731 is rotatably provided in a groove on a side wall of one side of the connecting block 73. The ball bearing 731 is in contact with the pushing head 63, and the ball bearing 731 is convenient for sliding on the pushing head 63.

[0032] Among them, a cylinder fixed front seat 11 is arranged on the side wall of one side of the connecting plate 1, and the cylinder fixed front seat 11 is connected to the piston rod at the output end of the cylinder 71. The cylinder fixed front seat 11 facilitates the cylinder 71 to push the connecting plate 1 to move.

[0033] Among them, a slider 12 is arranged on the side wall surface of one side of the connecting plate 1, and the slider 12 is slidably arranged on the slide rail 72. A guide rail 13 is arranged on the front surface of the connecting plate 1, and the pushing head 63 is slidably arranged on the guide rail 13. A reducer guard 2 is arranged on the outside of the fine-tuning mechanism 6, and a handwheel 3 is connected to one side of the fine-tuning mechanism 6.

[0034] Among them, a limit block 14 is provided on the surface of the connecting plate 1 on one side of the flip adjustment seat 4, and the limit block 14 is located on one side of the flip shaft 41.

When a small distance adjustment is required, the threaded rod 62 can be controlled to rotate by the drive component 61.

[0036] When the threaded rod 62 rotates, because the bottom pushing head 63 is on the guide rail 13, the pushing head 63 can only move straight up and down. When the pushing head 63 moves straight, the ball bearing 731 will slide on one side surface of the pushing head 63, sliding from the straight surface to the inclined surface, and when sliding on the inclined surface, a small gap will be generated between the ball bearing 731 and the pushing head 63, so that the cylinder 71 can only be adjusted by a small distance, thereby realizing the fine adjustment of the distance of the scraper on the coating scraper box 001.

[0037] And when the material box is turned over, the turning shaft 41 hits the top of the plastic head screw 432, and the turning shaft locking cylinder 8 pushes the locking slider 9 and makes the locking slider 9 press the bearing of the turning shaft 41 to contact the limit block 14, thereby achieving a buffering effect.

[0038] In the utility model, the fine adjustment of the distance is achieved by the fine adjustment mechanism 6, so that the distance between the blade and the coating roller is more accurate, the pressure bearing strength of the scraper blade is reduced, and the wear of the screen roller and the scraper blade is saved, thereby ensuring the accuracy of the adjustment. The buffer mechanism 43 and the flip shaft locking cylinder 8 and the locking slider 9 can support the flip shaft 41 under the cooperation of the set buffer mechanism 43 and the flip shaft locking cylinder 8 and the locking slider 9, thereby reducing the direct impact of the flip shaft on the limit block 14 by adjusting the air pressure.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
