Description

Technical Field

[0001] This utility model relates to the field of lithium battery film slitting machine technology, and in particular to a frame for a lithium battery film slitting machine. Background Technology

[0002] In lithium battery manufacturing, the slitting of thin-film materials is one of the key processing steps. Traditional slitting equipment generally suffers from insufficient structural rigidity and significant vibration, affecting slitting accuracy and edge quality. Existing slitting machines often use fixed blade holders, requiring manual adjustment by loosening bolts one by one when adjusting the blade position. This operation is cumbersome and makes it difficult to ensure the parallelism between multiple blades. Furthermore, replacing or maintaining blades requires stopping the machine, and the limited operating space leads to low efficiency. In addition, traditional equipment lacks an integrated power transmission and lifting control structure, resulting in unstable pressure during slitting and affecting the yield. Therefore, there is an urgent need for a new type of slitting machine frame with a high-rigidity frame, quickly adjustable blade spacing, and the ability to lift the entire blade holder to meet the production requirements of efficient and high-precision slitting of lithium battery films. However, existing lithium battery film slitting machine frames still suffer from the problem of blade wobbling during installation, making it difficult to accurately move the blades onto the battery film.

[0003] Therefore, it is essential to invent a frame for a lithium battery film slitting machine. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a lithium battery film slitting machine frame, solving the issue that existing lithium battery film slitting machine frames still suffer from blade wobbling during installation, making it difficult to accurately move the blade onto the battery film. A lithium battery film slitting machine frame includes a support frame, a mounting frame, a connecting seat, a slitting blade holder, a drive motor, and a support roller. The mounting frame is fixedly installed at the rear of the support frame and mounted on the slitting machine via the mounting frame. The connecting seat is fixedly installed below the front end of the support frame, and the slitting blade holder is installed above the support frame. The drive motor is fixedly installed on the outer side of the slitting blade holder. The slitting blade holder is rotatably mounted on the inner side of the slitting blade holder, and the support roller is rotatably mounted on the inner side of the connecting seat via the motor.

[0005] The slitting tool holder includes a rear rotating seat, a drive push rod, a rotating bracket, a front rotating seat, and a tool holder. The rear rotating seat is fixedly installed on the top of the rear side of the support frame, and the tail end of the drive push rod is rotatably installed on the rear rotating seat. The front rotating seat is fixedly installed on the top of the front side of the support frame, and the rotating bracket is rotatably installed on the inner side of the front rotating seat. The drive push rod and the rotating bracket are rotatably mounted together via a rotating shaft. The tool holder is fixedly installed on the front end of the rotating bracket.

[0006] The slitting blade holder includes a rotating connecting seat, a support shaft, a tool holder, a clamping blade, and a slitting blade. The rotating connecting seat is installed inside the tool holder, and the support shaft is rotatably installed inside the rotating connecting seat. One end of the support shaft is connected to the output shaft of the drive motor. The tool holder is fixedly installed on the surface of the support shaft, and the clamping blade is fixedly installed on the outside of the tool holder. The slitting blade is slidably installed on the surface of the support shaft and is clamped and fixed by two sets of clamping blades.

[0007] The rotating bracket inside the slitting tool holder uses two sets of rectangular steel plates, and the rotating bracket can rotate through the front rotating seat, thereby driving the slitting tool holder away from or towards the support roller through the tool holder; the rotating bracket is operated by the extension and retraction of the drive push rod.

[0008] The slitting blade inside the slitting blade holder is a pair of parallel circular blades, and the outer edge of the slitting blade is annularly sharpened. The slitting blade can be held in place by two sets of clamping blades. The slitting blade can rotate on the support shaft by the drive motor.

[0009] Compared with the prior art, the present invention has the following beneficial effects: The slitting tool holder of this utility model is designed to drive the rotating bracket to rotate with the front rotating seat as the fulcrum through the extension and retraction of the drive push rod. This allows the slitting tool holder and slitting blade mounted on the tool holder to perform lifting and lowering movements as a whole. When pressed down, the slitting blade engages with the support roller to slitting the film. When lifted up, it provides a safe space for tool replacement and maintenance. At the same time, the frame also provides a fixed support for the drive motor to transmit power to the support shaft.

[0010] The slitting blade holder of this utility model is installed on the blade holder of the slitting blade holder by a rotating connecting seat, and the support shaft is driven to rotate by a drive motor, which in turn drives the blade holder, blade holder and slitting blade held and fixed on its surface to rotate at high speed, so as to accurately slit the lithium battery film conveyed on the support roller.

[0016] As attached Figure 1 To be continued Figure 3 As shown.

[0017] This utility model provides a frame for a lithium battery film slitting machine, including a support frame 1, a mounting frame 2, a connecting seat 3, a slitting cutter holder 4, a drive motor 5, a slitting cutter holder 6, and a support roller 7. The mounting frame 2 is fixedly installed at the rear of the support frame 1 and is mounted on the slitting machine via the mounting frame 2. The connecting seat 3 is fixedly installed below the front end of the support frame 1, and the slitting cutter holder 4 is installed above the support frame 1. The drive motor 5 is fixedly installed on the outside of the slitting cutter holder 4. The slitting cutter holder 6 is rotatably mounted inside the slitting cutter holder 4, and the support roller 7 is rotatably mounted inside the connecting seat 3 via the motor.

[0018] The slitting tool holder 4 includes a rear rotating seat 41, a drive push rod 42, a rotating bracket 43, a front rotating seat 44, and a tool holder 45. The rear rotating seat 41 is fixedly installed on the top of the rear side of the support frame 1, and the tail end of the drive push rod 42 is rotatably installed on the rear rotating seat 41. The front rotating seat 44 is fixedly installed on the top of the front side of the support frame 1, and the rotating bracket 43 is rotatably installed on the inner side of the front rotating seat 44. The drive push rod 42 and the rotating bracket 43 are rotatably mounted together via a rotating shaft. The tool holder 45 is fixedly installed on the front end of the rotating bracket 43.

[0019] The slitting blade holder 6 includes a rotating connecting seat 61, a support shaft 62, a tool holder 63, a clamping blade 64, and a slitting blade 65. The rotating connecting seat 61 is installed inside the tool holder 45, and the support shaft 62 is rotatably installed inside the rotating connecting seat 61. One end of the support shaft 62 is connected to the output shaft of the drive motor 5. The tool holder 63 is fixedly installed on the surface of the support shaft 62, and the clamping blade 64 is fixedly installed on the outside of the tool holder 63. The slitting blade 65 is slidably installed on the surface of the support shaft 62 and is clamped and fixed by two sets of clamping blades 64.

[0020] The rotating bracket 43 inside the slitting tool holder 4 is made of two sets of rectangular steel metal plates, and the rotating bracket 43 can be rotated through the front rotating seat 44, thereby driving the slitting tool holder 6 away from or closer to the support roller 7 through the tool holder 45; the rotating bracket 43 is operated by the extension and retraction of the drive push rod 42.

[0021] The slitting blade 65 inside the slitting blade holder 6 is a pair of parallel circular blades, and the outer edge of the slitting blade 65 is annularly sharpened. The slitting blade 65 can be held in place by two sets of clamping blades 64. The slitting blade 65 can rotate on the support shaft 62 by the drive motor 5.

[0022] The overall working principle of the lithium battery film slitting machine frame involved in this utility model is as follows: After the equipment is started, the lithium battery film roll to be slitting will pass through the area between the support roller 7 and the slitting blade holder 6. At this time, the drive push rod 42 in the slitting blade holder 4 extends, pushing the rotating bracket 43 to rotate downward with its front rotating seat 44 as the fulcrum, thereby driving the blade holder 45 at its front end and the entire slitting blade holder 6 mounted on it to swing downward, so that the slitting blades 65 on the slitting blade holder 6 are precisely pressed against the film on the surface of the support roller 7. At the same time, the drive motor 5 starts, and its power output is sent to the support shaft 62 of the slitting blade holder 6, driving the support shaft 62 to rotate at high speed. The blade holder 63 and blade holder 64 fixed on the support shaft 62 rotate accordingly, clamping all the slitting blades 65 and rotating together. On the other hand, the support roller 7 also rotates actively under the drive of its own motor, conveying the film. The sharp edge of the rotating slitting blade 65 forms a precise shearing action with the roller surface of the support roller 7, thereby slitting the wide lithium battery film into multiple narrow strips of the required width. When blade replacement or maintenance is required, the drive push rod 42 retracts, raising the slitting blade holder 6 as a whole, so that the slitting blade 65 is away from the support roller 7, allowing for safe and convenient operation.

[0023] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
