Description

Technical Field

[0001] The utility model relates to the technical field of pole piece processing equipment, and particularly relates to a lithium battery pole piece rolling mill which is convenient for replacing rolls. Background Art

[0002] When manufacturing lithium battery pole pieces, rolling is required through two relatively rotating rolls in a rolling mill, so as to achieve the purpose of compacting the density of the pole pieces and enhancing the bonding strength between the active material and the current collector foil. However, during the long-term rolling process, the surface of the roll will gradually wear due to friction with the material. This wear will cause the accuracy of the roll to decline, affect the product quality, and make the roll need to be frequently disassembled and replaced. Due to the large weight of the roll, when replacing the roll, it is necessary to first fix the roll with a crane, then disassemble the locking device of the roll by workers, and finally the workers start the crane to lift the roll away. This not only has a complex operation, but also has a low efficiency of removing the roll, greatly reducing the production efficiency of the pole pieces. Content of the Utility Model

[0003] The purpose of the utility model is to provide a lithium battery pole piece rolling mill which is convenient for replacing rolls to solve the above problems.

[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0031] like Figures 1-5 As shown, a lithium battery pole piece rolling mill that is convenient for replacing rollers comprises:

[0032] Box 1;

[0033] A mounting frame 2 symmetrically arranged in the box body 1;

[0034] Rotate the arc-shaped locking block 5 disposed on the top of the mounting frame 2;

[0035] A roller 6 slidably disposed in the mounting frame 2 and abutting against the arc-shaped locking block 5;

[0036] The roll removing assembly at least comprises a roll removing frame 12 which is rotatably arranged in the box body 1 and arranged in the same horizontal line with the rolling roller 6, and an arc-shaped supporting plate 16 is symmetrically arranged on the roll removing frame 12.

[0037] Specifically, the roller 6 is placed on the mounting frame 2, and the arc locking block 5 is driven to rotate and clamped on the mounting frame 2, so that the arc locking block 5 locks the roller 6 on the mounting frame 2, so that the roller 6 can rotate in the mounting frame 2 to roll the pole piece. When the roller 6 needs to be disassembled, the roller removal frame 12 is driven to rotate toward the roller 6, so that the roller removal frame 12 unlocks the arc locking block 5 clamped on the mounting frame 2, and at the same time drives the arc support plate 16 to extend to the bottom of the roller 6. The arc support plate 16 is driven by the roller removal frame 12 to rotate continuously, so that the arc support plate 16 lifts the roller 6 during the rotation, and drives the roller 6 to separate from the mounting frame 2, so that the roller 6 can be quickly removed.

[0038] In the above embodiments, by providing a mounting frame 2, an arc-shaped locking block 5, a rolling roll 6, a roll removal frame 12, and an arc-shaped support plate 16 inside the box body 1, it is convenient for workers to disassemble and replace the rolling roll 6. The rolling roll 6 is locked in the mounting frame 2 by the arc-shaped locking block 5, so that when the rolling roll 6 is driven, it can rotate to roll the pole piece. When the rolling roll 6 needs to be disassembled, since the rolling roll 6 is located on the rotation path of the roll removal frame 12 and the arc-shaped support plate 16, workers can drive the roll removal frame 12 to drive the arc-shaped support plate 16 to rotate, and then quickly remove the rolling roll 6. This not only has a simple operation but also a high working efficiency, improving the removal efficiency of the rolling roll 6.

[0039] As a further embodiment provided by the present utility model, a rotating shaft 3 is fixedly installed at the top end of the mounting frame 2, a torsion spring 4 is fixedly installed inside the rotating shaft 3, and an arc-shaped locking block 5 is movably connected to the rotating shaft 3.

[0040] Specifically, the torsion spring 4 provides elastic force to the rotating shaft 3, enabling workers to drive the arc-shaped locking block 5 to rotate along the rotating shaft 3 and engage with the mounting frame 2, thereby locking the rolling roll 6. At the same time, the torsion spring 4 can deform and store energy. When the arc-shaped locking block 5 disengages from the engagement, the torsion spring 4 drives the rotating shaft 3 to rotate, causing the rotating shaft 3 to drive the arc-shaped locking block 5 to rotate and disengage from the mounting frame 2, thus unlocking the rolling roll 6.

[0041] As another further embodiment provided by the present utility model, a groove 8 is opened at the top end of the mounting frame 2, a spring 9 is fixedly installed inside the groove 8, and a buckle 10 is fixedly installed on the end face of the spring 9.

[0042] Furthermore, a lock catch 7 is fixedly installed at the bottom end of the arc-shaped locking block 5, and the side wall of the lock catch 7 abuts against the buckle 10.

[0043] Specifically, when the arc-shaped locking block 5 drives the lock catch 7 to move into the groove 8, the spring 9 provides a thrust to the buckle 10, causing the buckle 10 to abut against the lock catch 7, thereby locking the arc-shaped locking block 5. When the arc-shaped locking block 5 needs to be unlocked, by pushing the buckle 10 to disengage from the lock catch 7, the lock catch 7 can be unlocked.

[0044] As another further embodiment provided by the present utility model, push blocks 17 are symmetrically arranged on the side wall of the roll removal frame 12.

[0045] Specifically, during the rotation of the roll removal frame 12, the push blocks 17 are driven to abut and push the buckle 10, so that the lock catch 7 can be unlocked during the rotation of the roll removal frame 12, thereby causing the arc-shaped locking block 5 to disengage from the mounting frame 2.

[0046] As another further embodiment provided by the present utility model, a sliding rod 13 is fixedly installed inside the box body 1, the roll removal frame 12 is fixedly connected to the sliding rod 13, a driving block 14 is movably installed inside the roll removal frame 12, and a driving shaft 15 is fixedly installed inside the driving block 14.

[0047] Furthermore, a motor 18 is fixedly installed on the side wall of the box body 1, and the output end of the motor 18 is fixedly connected to the driving shaft 15.

[0048] Specifically, the motor 18 provides a rotational force to the driving shaft 15, causing the driving shaft 15 to drive the driving block 14 to rotate. The driving block 14 drives the roll removing frame 12 to rotate towards the roll 6, enabling the roll removing frame 12 to drive the arc-shaped supporting plate 16 to remove the roll 6 during rotation. The slide rod 13 restricts the roll removing frame 12, allowing the roll removing frame 12 to rotate stably within the box body 1.

[0049] Working principle: Place the roll 6 on the mounting frame 2 and drive the arc-shaped locking block 5 to rotate along the rotating shaft 3 and abut against the mounting frame 2, causing the lock catch 7 installed on the arc-shaped locking block 5 to move into the groove 8. The spring 9 pushes the buckle 10 to abut against the lock catch 7, enabling the arc-shaped locking block 5 to be clamped onto the mounting frame 2 to lock the roll 6. Thus, when the roll 6 is driven, it can rotate within the mounting frame 2 to roll the pole piece. When the roll 6 needs to be disassembled, drive the driving shaft 15 to rotate through the motor 18, causing the driving shaft 15 to drive the driving block 14 to rotate within the roll removing frame 12. Consequently, the driving shaft 15 drives the roll removing frame 12 to rotate towards the roll 6. The roll removing frame 12 drives the push block 17 to move towards the roll 6, causing the push block 17 to squeeze the buckle 10, thereby unlocking the arc-shaped locking block 5. The roll removing frame 12 drives the arc-shaped supporting plate 16 to extend to the bottom of the roll 6, enabling the arc-shaped supporting plate 16 to lift the roll 6 during rotation and drive the roll 6 to disengage from the mounting frame 2, allowing the roll 6 to be quickly disassembled.

[0050] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
