This utility model, by setting up components such as a threaded rod, a connecting plate, and a square block, allows the roller to be disassembled by rotating the threaded rod, causing the threaded rod and the connecting plate to move in a threaded motion. This causes the connecting plate to move the bracket, which in turn causes the square block to slide out of the roller. This solves the problem that the rollers of the thin sheet winding device used in lithium battery processing are inconvenient to disassemble and replace during use.
[0014] 2. This utility model is equipped with components such as a push plate, a locking block, and a spring. The spring force can drive the push plate to move, causing the push plate to slide the locking block into the knob, thus limiting the knob's position. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-5 A thin-film winding device for lithium battery processing includes a base 1, with a bracket 2 in contact with the outer side of the base 1. Two brackets 2 are in contact with square blocks 3 on their adjacent sides. A rotating shaft 31 is connected to the inside of one bracket 2 via a bearing. A motor 32 is fixedly mounted on the other bracket 2, and the output end of the motor 32 is rotatably connected to the bracket 2. One square block 3 is fixedly connected to the rotating shaft 31, and the other square block 3 is fixedly connected to the output end of the motor 32. A connecting plate 4 is slidably connected inside the base 1. A connecting rod 41 is fixedly connected to the side of the connecting plate 4 near the bracket 2. The connecting rod 41 is slidably connected to the base 1 and fixedly connected to the bracket 2. The design of the connecting rod 41 allows the connecting plate 4 to drive the bracket 2 to move. A threaded rod 42 is connected to the inside of the base 1 via a bearing.
[0023] Please see Figure 2-5The threaded rod 42 has positive and negative threads on its outer side. The threaded rod 42 is connected to the connecting plate 4 by threads. The design of the threaded rod 42 can drive the two connecting plates 4 to move simultaneously. The base 1 is rotatably connected to the connecting shaft 43. The outer side of the connecting shaft 43 is fixedly connected to the retaining ring 44. The retaining ring 44 contacts the inner wall of the base 1. The design of the retaining ring 44 can limit the movement of the connecting shaft 43. The side of the connecting shaft 43 near the threaded rod 42 is fixedly connected to the first bevel gear 45. The outer side of the threaded rod 42 is fixedly connected to the second bevel gear 46. The first bevel gear 45 and the second bevel gear 46 mesh. The side of the connecting shaft 43 away from the first bevel gear 45 is fixedly connected to the knob 47. The knob 47 is rotatably connected to the base 1. The base 1 is provided with a limit mechanism 5. Rollers 6 are in contact between the brackets 2. Square blocks 3 are slidably connected inside the rollers 6.
[0024] Please see Figure 2-5 The limiting mechanism 5 includes a push plate 51, which is slidably connected to the base 1. A locking block 52 is fixedly connected to the side of the push plate 51 near the knob 47. The locking block 52 is slidably connected to the base 1 and the knob 47. The locking block 52 can limit the movement of the knob 47. A slide rod 53 is fixedly connected to the side of the push plate 51 away from the locking block 52. The slide rod 53 is slidably connected to the base 1. A baffle 54 is fixedly connected inside the base 1. The baffle 54 is connected to the slide rod 53. 3.

One end of the spring 55 is in contact with the sliding rod 53, and the other end of the spring 55 is in contact with the base 1. By moving the push plate 51 away from the knob 47, the push plate 51 drives the sliding rod 53 to slide in the baffle 54, so that the sliding rod 53 squeezes the spring 55, and the push plate 51 drives the locking block 52 to slide out of the knob 47, thus releasing the limitation on the knob 47.
[0025] The specific implementation process of this utility model is as follows: When in use, by moving the push plate 51 away from the knob 47, the push plate 51 drives the slide rod 53 to slide in the baffle 54, so that the slide rod 53 squeezes the spring 55, and the push plate 51 drives the locking block 52 to slide out of the knob 47, thus releasing the limitation on the knob 47.
[0026] By rotating the knob 47, the threaded rod 42 is rotated, causing the threaded rod 42 to move in a threaded motion with the connecting plate 4. This causes the connecting plate 4 to move on the threaded rod 42, which in turn causes the connecting rod 41 to move, which in turn causes the bracket 2 to move. This causes the bracket 2 to slide the square block 3 out of the roller 6, thus releasing the limit on the roller 6 and allowing the roller 6 to be disassembled.
