Technical Field

[0001] The utility model relates to the technical field of coating equipment, in particular to a pneumatic locking mechanism for a closed material box scraper blade. 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] When installing the scraper blade of the scraper box cavity of some coating machines, most of them use a large number of screws to lock it, or use an eccentric mechanism to squeeze the tail wing of the pressure plate so that the pressure plate forms a crowbar principle to clamp the scraper blade. However, this installation method is more cumbersome and takes a long time, resulting in low installation efficiency. Utility Model Content

[0007] The pneumatic locking mechanism comprises an airbag, which is arranged in the groove. One end of the airbag tube body is connected to an air inlet end, and the other end of the airbag tube body away from the air inlet end is connected to an air blocking end.

[0008] In addition, a preferred structure is that the air inlet end includes a first fixed seat, the first fixed seat is arranged at the connection between the air inlet end and the airbag, a first locking ring is arranged at the inner circle of the first fixed seat, and the other end of the first fixed seat away from the airbag is connected to a double-threaded right-angle pipe connection, and an air inlet is arranged on the double-threaded right-angle pipe connection.

[0009] In addition, a preferred structure is that the gas blocking end includes a second fixing seat, the second fixing seat is arranged at the connection between the gas blocking end and the airbag, a second locking ring is arranged at the inner circle of the second fixing seat, and a sealing pin is connected to the other end of the second fixing seat away from the airbag.

[0010] In addition, a preferred structure is that a coating roller is provided on one side of the scraper box cavity.

DETAILED DESCRIPTION

[0018] 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.

[0019] Reference Figure 1-4The pneumatic locking mechanism of the closed material box scraper blade includes a scraper material box cavity 1. Grooves 11 are transversely opened on the top and bottom surfaces of the scraper material box cavity 1. A pneumatic locking mechanism 2 is arranged at the groove 11. The pneumatic locking mechanism 2 includes an airbag 21. The airbag 21 is arranged in the groove 11. One end of the airbag 21 tube body is connected to an air inlet end 22. The other end of the airbag 21 tube body away from the air inlet end 22 is connected to an air blocking end 23. The airbag 21 is locked by inflating.

[0020] Among them, the air inlet end 22 includes a first fixed seat 222, which is arranged at the connection between the air inlet end 22 and the airbag 21, and a first locking ring 221 is arranged at the inner circle of the first fixed seat 222, and the other end of the first fixed seat 222 away from the airbag 21 is connected with a double-threaded right-angle pipe connection 223, and the double-threaded right-angle pipe connection 223 is provided with an air inlet 224, which is convenient for gas supply.

[0021] In addition, the gas blocking end 23 includes a second fixed seat 232, which is arranged at the connection between the gas blocking end 23 and the airbag 21. A second locking ring 231 is arranged at the inner circle of the second fixed seat 232, and a sealing pin 233 is connected to the other end of the second fixed seat 232 away from the airbag 21. The sealing pin 233 can prevent gas leakage.

[0022] Among them, a coating roller 001 is arranged on one side of the scraper box cavity 1, and a scraper pressure plate 3 is arranged on the inclined surface of the scraper box cavity 1 located close to the coating roller 001. The upper surface of the scraper pressure plate 3 is located above the groove 11, and a scraper blade 4 is arranged between the scraper pressure plate 3 and the scraper box cavity 1, and the scraper blade 4 is pressed by the scraper pressure plate 3.

[0023] In this embodiment, the airbag 21 is first installed in the groove 11, and then the scraper pressing plate 3 is placed in the groove of the scraper material box cavity, and the scraper blade 3 is inserted from the gap to the bottom of the scraper pressing plate 3, and then air is supplied to the airbag 21 from the air inlet end 22, so that the airbag 21 expands in the groove 11 to lift the tail of the scraper pressing plate 3, forming a lever principle to clamp the scraper blade 4, and the eccentric circular notch on the inner side of the pressing plate is conducive to anti-slip and controlling the direction of the airbag expansion.

[0024] In the utility model, a pair of pneumatic locking mechanisms 2 are arranged on the scraper material box cavity 1. After air is supplied from the air inlet end 22 to the airbag 21, the airbag 21 expands in the groove 11 to lift the tail of the scraper pressure plate 3, forming a lever principle to clamp the scraper blade 4. The eccentric circular notch on the inner side of the pressure plate is beneficial for anti-slip and controlling the direction of the airbag expansion. This pneumatic locking method is more convenient to operate. It only needs to inflate the airbag 21 to press down the scraper blade 4, thereby fixing it. This process does not need to consume too much time, thereby effectively improving the installation time and helping users to improve work efficiency.
