And the loss of the net roller and the scraper blade is reduced. Therefore, the adjustment precision is ensured.

Description

Technical Field

[0001] The utility model relates to the technical field of coating equipment, in particular to a scraper blade fine adjustment mechanism for micro-concave coating. 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] Most of the existing diaphragm coating machines use cylinders to adjust when moving a coating scraper box with a scraper close to a coating roller. However, when the coating scraper box needs to be adjusted a small distance, the traditional cylinder cannot meet the requirements of fine adjustment, which will cause deviations in the moving distance, resulting in serious wear and tear of the coating roller and the blade.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-6 The micro-concave coating scraper blade fine-adjustment mechanism includes a connecting wall panel fixing plate 002, a slide rail 0022 is arranged on the surface of one side of the connecting wall panel fixing plate 002, a connecting plate 1 is slidably arranged on the slide rail 0022, and a fine-adjustment mechanism 6 is installed on the connecting plate 1, through which the connecting plate 1 can be moved a small distance on the slide rail 0022.

[0024] Among them, the fine adjustment mechanism 6 includes a driving component 61, a threaded rod 62 is assembled and connected on the output end of the driving component 61, a connecting head 63 is assembled and installed at the bottom of the rod body of the threaded rod 62, a pushing block 64 is installed at the bottom of the side wall of one side of the connecting head 63, and sliding grooves 641 are symmetrically opened on the side walls of both sides of the pushing block 64. A straight surface part 642 is arranged on the surface of one side of the pushing block 64, and a conical surface part 643 is arranged below the straight surface part 642. Through the vertical movement of the pushing block 64, micro adjustment can be performed.

[0025] Among them, a cylinder 0021 is arranged at the rear end of the plate body of the connecting wall panel fixing plate 002, a piston rod assembled at the output end of the cylinder 0021 is connected to the connecting plate 1, a connecting block 0023 is arranged at the front end of the plate body of the connecting wall panel fixing plate 002, a ball bearing 00231 is rotatably arranged in the groove of the side wall of one side of the connecting block 0023, the ball bearing 00231 is in contact with the pushing block 64, and the ball bearing 00231 is convenient for driving the connecting block 0023 to be pushed out while rolling.

[0026] In addition, a cylinder fixed front seat 11 is provided 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 0021. The cylinder fixed front seat 11 is used to be pushed by the piston rod of the cylinder 0021, so as to realize the sliding of the slider 12 on the slide rail 0022.

[0027] 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 0022. A guide rail 13 is arranged on the front surface of the connecting plate 1, and a push block 64 is slidably arranged on the guide rail 13. The push block 64 moves up and down on the guide rail 13, so that when the threaded rod 62 rotates, the connecting head 63 can only convert the rotational motion into linear motion.

[0028] A reducer shield 2 is disposed outside the fine adjustment mechanism 6 , and a hand wheel 3 is connected and disposed on one side of the fine adjustment mechanism 6 .

[0029] In addition, a flip adjustment seat 4 is connected to one side of the connecting plate 1, a connecting seat 5 is arranged on the front side of the flip adjustment seat 4, and a coating scraper material box 001 is installed on the front side of the connecting seat 5.

[0030] In this embodiment, the cylinder 0021 is set to push the cylinder fixed front seat 11 to move, so that the slider 12 slides on the slide rail 0022, thereby adjusting the distance between the scraper and the coating roller on the coating scraper box 001. When a small distance adjustment is required, the threaded rod 62 can be controlled to rotate by the drive component 61.

[0031] When the threaded rod 62 rotates, the connecting head 63 can only move linearly up and down because the bottom pushing block 64 is on the guide rail 13. When the pushing block 64 moves linearly, the ball bearing 00231 will slide on one side surface of the pushing block 64, from the straight surface portion 642 to the conical surface portion 643, and when sliding on the conical surface portion 643, a small gap will be generated between the ball bearing 00231 and the pushing block 64. To ensure that the ball bearing 00231 is always in contact with the conical surface, the cylinder 0021 is required to pull it. However, due to the limitation of the pushing block 64, the cylinder 0021 can only be adjusted by a small distance, thereby achieving fine adjustment of the distance of the scraper on the coating scraper box 001.

[0032] In the utility model, a static adjustment mechanism 6 is provided on the connection plate 1 on which the coating scraper material box 001 is installed, so that when it is necessary to fine-tune the distance between the scraper on the coating scraper material box 001 and the coating roller, the push block 64 can be provided to move up and down, so that the connection block 0023 pulled by the cylinder 0021 can only pull the slider 12 to move a small distance because of the inclined surface limit of the push block 64, thereby achieving fine adjustment of the distance, making the distance between the blade and the coating roller more accurate, reducing the pressure bearing strength of the scraper blade, saving the wear of the screen roller and the scraper blade, and ensuring the accuracy of the adjustment.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. 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.
