Description

Technical Field

[0001] This utility model relates to the field of battery electrode rolling technology with a slitting structure, and more particularly to a battery electrode rolling method with a slitting structure. Background Technology

[0002] Roller presses, also known as double-roll mills, rolling mills, or tablet presses, are widely used in industries such as chemical and electronics. They process raw materials by extruding them using the pressure generated by the opposing movement of upper and lower rollers to meet specific technological requirements. The rollers are made of 9Cr2Mo steel with a 5mm hardening depth. They offer advantages such as adjustability, high hardness, high precision, automation, and ease of operation.

[0003] The inventors discovered during routine use of the roller press that, when rolling battery electrodes, the lack of a slitting component on the surface of the rollers prevented the pre-pressed battery electrodes from being preliminarily divided, thus affecting subsequent operations and causing problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a battery electrode rolling process with a slitting structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a battery electrode sheet rolling mill with a slitting structure, comprising a rolling mill, a pressure roller rotatably connected to the side of the rolling mill, a slitting device provided on the surface of the pressure roller, a drive assembly provided on the side of the rolling mill, a cleaning device provided at the bottom of the pressure roller, an adjusting rod provided at the top of the rolling mill, and the slitting device comprising a ring provided on the surface of the pressure roller, wherein a cutter is fixedly connected to the surface of the ring.

[0006] The effect achieved by the above components is as follows: under the action of the cutter, the battery grade sheet can be cut after being pressed, thereby achieving the function of cutting. When the battery grade sheet is pressed by the roller press, the battery grade sheet is placed between the two rollers, and the appropriate thickness is adjusted by the adjusting rod. After adjustment, the pressure roller is driven by the drive component, thereby pressing the battery grade sheet.

[0007] Preferably, a rectangular plate is fixedly connected to the side of the ring, and a clamping rod is inserted into the side of the rectangular plate, with one end of the clamping rod inserted into the interior of the pressure roller.

[0008] The effect achieved by the above components is that, under the action of the lever, the ring can be moved to a suitable position and fixed, thereby allowing the width of the battery plate to be adjusted, thus achieving the adjustment function.

[0009] Preferably, the inner wall of the ring is provided with a circular groove, and a ball bearing is rotatably connected inside the circular groove.

[0010] The effect achieved by the above components is that the friction between the ring and the pressure roller is reduced under the action of the balls, thus facilitating movement.

[0011] Preferably, a first spring is sleeved on the surface of the clamp rod, and the two ends of the first spring are fixedly connected to one end of the clamp rod on the side of the rectangular plate.

[0012] The effect achieved by the above components is as follows: under the action of the first spring, the locking rod is inserted into the inside of the pressure roller for fixation. When the position of the cutter needs to be adjusted, the locking rod is pulled outward, so that the ring moves through the ball bearings. When it moves to the appropriate position, under the action of the first spring, the locking rod is inserted into the inside of the pressure roller for fixation, thereby achieving the function of cutting battery cells.

[0013] Preferably, the cleaning device includes a round rod fixedly connected to the side of the roller press, and a scraper is fixedly connected to the surface of the round rod, the scraper being in close contact with the surface of the pressure roller.

[0014] The effect achieved by the above components is that, under the action of the scraper, the impurities adhering to the surface of the pressure roller can be cleaned, thus preventing the battery cells from sticking to the surface of the pressure roller and becoming unusable during the next use.

[0015] Preferably, a long plate is fixedly connected to the side of the roller press, and a brush is provided on one side of the long plate.

[0016] The effect achieved by the above components is that, under the action of the brush, the pressure roller can be cleaned again after cleaning, thereby cleaning the surface of the pressure roller.

[0017] Preferably, a slide rod is slidably connected to the surface of the long plate, and a second spring is sleeved on the surface of the slide rod. The two ends of the second spring are respectively fixedly connected to one end of the slide rod on the side of the long plate, and a brush is fixedly connected to one end of the slide rod.

[0018] The effect achieved by the above components is that, under the action of the second spring and the slide bar, the brush can always be kept in close contact with the surface of the pressure roller for cleaning.

[0019] Preferably, a collection frame is provided at the bottom of the pressure roller, and the collection frame is slidably connected to the side of the roller press.

[0020] The above components achieve the following effects: under the action of the collection frame, the cleaned material can fall into the collection frame for collection; when the pressure roller is in use, the scraper can clean the material adhering to the surface of the pressure roller; under the action of the brush, the residual material is swept off and falls into the collection frame for collection; under the action of the second spring and the slide bar, the brush can always be in close contact with the surface of the pressure roller for cleaning, thereby achieving the cleaning effect.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, by setting a slitting device, when the position of the cutter needs to be adjusted, the locking rod is pulled outward, so that the ring moves through the ball bearings. When it moves to the appropriate position, under the action of the first spring, the locking rod is self-locking and inserted into the inside of the pressure roller for fixation, thereby achieving the function of slitting battery cells and solving the problem that the roller press cannot divide battery cells during the rolling process.

When the rolling press 1 is used to press the battery electrode sheet with the roller 4, the battery electrode sheet is placed between the two rollers, and the appropriate thickness is adjusted by the adjusting rod 5. After adjustment, the pressure roller 4 is driven by the drive assembly, thereby pressing the battery electrode sheet.

[0028] Reference Figure 2 The slitting device 2 includes a ring 21 disposed on the surface of the pressure roller 4. A cutter 22 is fixedly connected to the surface of the ring 21. Under the action of the cutter 22, the battery sheet can be slit after being pressed, thus achieving the slitting function. When the roller press 1 is used to press the battery sheet on the roller 4, the battery sheet is placed between the two rollers, and the appropriate thickness is adjusted by the adjusting rod 5. After adjustment, the pressure roller 4 is driven by the driving component, thus pressing the battery sheet. A rectangular plate 23 is fixedly connected to the side of the ring 21, and a locking rod 24 is inserted into the side of the rectangular plate 23. One end of the locking rod 24 is inserted into the interior of the pressure roller 4. Under the action of the locking rod 24, the ring 21 can be moved to a suitable position and fixed, thus allowing the width of the battery sheet to be adjusted, thereby achieving the adjustment function. The inner wall of the ring 21 has a circular groove, and a ball bearing 26 is rotatably connected inside the groove. Under the action of the ball bearing 26, the friction between the ring 21 and the pressure roller 4 is reduced, thus facilitating movement. A first spring 25 is sleeved on the surface of the clamping rod 24. The two ends of the first spring 25 are fixedly connected to the side of the rectangular plate 23 and one end of the clamping rod 24, respectively. Under the action of the first spring 25, the clamping rod 24 is self-locking and inserted into the pressure roller 4 for fixation. When it is necessary to adjust the position of the cutter 22, the clamping rod 24 is pulled outward, allowing the ring 21 to move through the ball bearing 26. When it moves to the appropriate position, under the action of the first spring 25, the clamping rod 24 is self-locking and inserted into the pressure roller 4 for fixation, thereby achieving the function of cutting battery cells.

[0029] Reference Figure 3The cleaning device 3 includes a round rod fixedly connected to the side of the roller press 1. A scraper 31 is fixedly connected to the surface of the round rod. The scraper 31 is in close contact with the surface of the pressure roller 4. Under the action of the scraper 31, the impurities adhering to the surface of the pressure roller 4 can be cleaned, avoiding the phenomenon that the battery cells will stick to the surface of the pressure roller 4 and become unusable during the next use. A long plate 32 is fixedly connected to the side of the roller press 1. A brush 34 is provided on one side of the long plate 32. Under the action of the brush 34, the pressure roller 4 can be cleaned again after cleaning, thereby cleaning the surface of the pressure roller 4. A sliding rod is slidably connected to the surface of the long plate 32. A second spring 35 is sleeved on the surface of the sliding rod. The two ends of the second spring 35 are respectively connected to the side of the long plate 32 and one end of the sliding rod. The roller 4 is fixedly connected at one end, and a brush 34 is fixedly connected to one end of the slide rod. Under the action of the second spring 35 and the slide rod, the brush 34 can always be in close contact with the surface of the pressure roller 4 for cleaning. A collection frame 33 is provided at the bottom of the pressure roller 4. The collection frame 33 is slidably connected to the side of the roller press 1. Under the action of the collection frame 33, the cleaned material can fall into the inside of the collection frame 33 for collection. When the pressure roller 4 is in use, the scraper 31 can clean the material adhering to the surface of the pressure roller 4. Under the action of the brush 34, the residual material is swept off and falls into the inside of the collection frame 33 for collection. Under the action of the second spring 35 and the slide rod, the brush 34 can always be in close contact with the surface of the pressure roller 4 for cleaning, thereby achieving the cleaning effect.

[0030] Working principle: When using a battery electrode sheet roller with a slitting structure, the battery electrode sheet is placed between two rollers when the roller press 1 is used to press the battery electrode sheet. The thickness is adjusted by adjusting rod 5. After adjustment, the roller 4 is driven by the drive assembly, thus pressing the battery electrode sheet. When the position of the cutter 22 needs to be adjusted, the locking rod 24 is pulled outward, so that the ring 21 moves through the ball bearing 26. When it moves to the appropriate position, under the action of the first spring 25, the locking rod 24 is self-locking and inserted into the inside of the roller 4 for fixation, thus achieving the function of slitting the battery electrode sheet. When the roller 4 is in use, the scraper 31 can clean the material adhering to the surface of the roller 4. Under the action of the brush 34, the residual material is swept down and falls into the inside of the collection frame 33 for collection. Under the action of the second spring 35 and the sliding rod, the brush 34 can always be in close contact with the surface of the roller 4 for cleaning, thus achieving the cleaning function.
