[0002] Lithium batteries are key equipment in the new energy industry. With the development of the new energy industry, the market demand for lithium batteries has also increased. In the production process of lithium batteries, the slitting process is a very important link. Lithium battery slitting refers to the process of precisely cutting a wide lithium battery pole piece into multiple narrow pole pieces of specific sizes through equipment such as a slitting machine, which is directly related to the quality and production efficiency of lithium batteries.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows: The continuous lithium battery slitting machine provided with a waste synchronous collection structure:

[0025] 1. In the present invention, the lithium battery raw material coil is cut and slit by a cutting knife. Below the cutting knife, a supporting plate and a baffle driven by a first electric push rod are provided. The supporting plate and the baffle rotatably connected to the surface form a box-shaped structure during the rising process to realize the synchronous collection of waste during the slitting process, avoiding waste accumulation. During the descending process of the supporting plate and the baffle, the baffle loses the support of the inner wall of the through hole on the upper base surface, and the rotating baffle opens both sides of the box-shaped structure, facilitating the collection of the collected waste.

[0026] 2. In the present invention, supporting structures are respectively arranged on both sides of the cutting knife. The preliminary support for the reel is realized through the sleeve. As the reel is inserted into the surface of the supporting roller along with the sleeve, the ejector rod connected to the sleeve is inserted into the inside of the supporting roller. The air in the inner airbag is pushed into the outer airbag by the ejector rod, causing the outer airbag to expand and fixing the reel on the outer surface of the supporting roller, enabling the device to be adaptively adjusted according to the size of the sleeve, closely fitting the reel, and increasing the stability of the reel during the slitting process.

[0027] Furthermore, a first pushing roller and a second pushing roller with a snap-fit connection are arranged between the cutting knife and the driving roller. During the connection process between the raw material and the device, the first pushing roller and the second pushing roller are used for temporary limiting between the cutting knife and the material receiving structure. As the driving roller rises, the first pushing roller and the second pushing roller move to both sides respectively, so that the supporting force of the first pushing roller and the second pushing roller on the raw material coil is switched to the supporting force of the driving roller, and the raw material is pushed to smoothly contact the cutting knife for slitting along with the rising of the driving roller, preventing the raw material from shifting and causing deviation during the slitting process.

A second outer side plate 7 is arranged in parallel on the side surface of the second inner side plate 6, and the second outer side plate 7 is fixedly installed on the upper surface of the upper base 1. Vertical plates 8 are respectively fixedly installed on both side surfaces of the second inner side plate 6, and the vertical plates 8 are fixedly connected to the surface of the second outer side plate 7. The second inner side plate 6, the second outer side plate 7, and the two vertical plates 8 form a hollow rectangular structure, and the length of the rectangular structure is shorter than the lengths of the first inner side plate 2 and the first outer side plate 3. Support structures are arranged on both sides of the cutting knife 5, and the support structures realize the preliminary support of the raw material reel and the finished product reel through the supporting roller 9. The support structure includes the supporting roller 9. The supporting roller 9 is arranged on one side of the cutting knife 5. The inside of the supporting roller 9 is hollow. One end of the supporting roller 9 penetrates through the surface of the first inner side plate 2 and is fixedly connected to the output end of the second motor 10, and the second motor 10 is fixedly installed on the surface of the first inner side plate 2.

[0043] As Figure 1 , Figure 2 , Figure 3As shown in the figure, during the process of slitting the raw materials of lithium batteries using this device, the raw material reel of the lithium battery to be slit is sleeved on the surface of the supporting structure on one side of the cutting knife 5, and the supporting reel after slitting is sleeved on the surface of the supporting structure on the other side of the cutting knife 5. Start the second electric push rod 27, and the second electric push rod 27 drives the supporting ring 26 to move. The moving supporting ring 26 exposes one end of the supporting roller 9. Sleeve the reel on the surface of the supporting roller 9. Restart the second electric push rod 27, and the second electric push rod 27 drives the supporting ring 26 to move in the reverse direction to support the supporting roller 9 again. After the reel and the supporting roller 9 are installed, pull out one end of the raw material from the surface of the raw material reel, bypass the upper surface of the connecting roller 16 and then bypass the lower surface of the cutting knife 5, and then bypass the upper surfaces of the first push roller 22 and the second push roller 23 and connect with the reel on the surface of the supporting structure on the other side of the cutting knife 5. Use the lifted driving roller 21 to make the raw material fully contact with the surface of the cutting knife 5. Start the second motor 10 at the supporting structure, so that the second motor 10 drives the supporting roller 9 to rotate, thereby using the rotating supporting roller 9 to drive the lithium battery raw material to be wound on the receiving reel surface and unwound on the surface of the raw material reel. Start the first motor 4, and the first motor 4 drives the cutting knife 5 to rotate. The rotating cutting knife 5 slits the raw material, and the lithium battery raw material after slitting is wound on the receiving reel surface.

[0044] A reinforcing structure is arranged on the outer surface of the supporting roller 9. The reinforcing structure realizes the reinforcement of the reel through the cooperation of the outer airbag 14 and the inner airbag 15. The reinforcing structure includes a sleeve 11. The sleeve 11 is a hollow cylindrical structure with both ends open. A plurality of long strip-shaped notches are annularly arranged on the outer surface of the sleeve 11. The sleeve 11 is sleeved on the outer surface of the supporting roller 9. A connecting block 12 is fixedly installed on the side surface of the sleeve 11. The connecting block 12 is an arc-shaped plate. A top rod 13 is fixedly installed on the surface of the connecting block 12. The top rod 13 is concentric with the sleeve 11. The top rod 13 is inserted into the inside of the supporting roller 9 from the open end of the supporting roller 9. The connecting block 12 and the supporting roller 9 are connected by bolts. An outer airbag 14 is connected to the outer surface of the supporting roller 9. The outer airbag 14 is an inflatable structure. A plurality of outer airbags 14 are annularly arranged on the outer surface of the supporting roller 9. The outer airbags 14 are arranged in one-to-one correspondence with the notches on the surface of the sleeve 11. An inner airbag 15 is arranged inside the supporting roller 9. The inner airbag 15 is connected to the outer airbag 14 through a pipeline. The same supporting structure and reinforcing structure are symmetrically arranged on both sides of the cutting knife 5. One set of supporting structure and reinforcing structure is marked as the feeding structure, and the other set of supporting structure and reinforcing structure is marked as the receiving structure. A connecting roller 16 is arranged between the feeding structure and the cutting knife 5. Both ends of the connecting roller 16 are rotatably installed on the surfaces of the first inner side plate 2 and the second inner side plate 6;

[0045] As Figure 9 、 Figure 10 and Figure 11As shown in the figure, during the process of connecting the supporting roller 9 to the winding drum, the bolts between the connecting block 12 and the supporting roller 9 are removed, and the connecting block 12, the ejector rod 13, and the sleeve 11 are simultaneously pulled out from the surface and inside of the supporting roller 9. The winding drum is sleeved on the outer surface of the sleeve 11, and the sleeve 11 is reconnected to the supporting roller 9. The long strip-shaped notch on the surface of the sleeve 11 is aligned and engaged with each outer airbag 14. At this time, the ejector rod 13 is inserted from the open end of the supporting roller 9, and the ejector rod 13 squeezes the inner airbag 15 inside the supporting roller 9. The air in the inner airbag 15 enters the inside of the outer airbag 14 along the through pipeline, causing the outer airbag 14 to expand. The expanded outer airbag 14 is used for the connection process between the sleeve 11, the supporting roller 9, and the winding drum. After the sleeving is completed, the connecting block 12 and the supporting roller 9 are reconnected using bolts, and the installation process between the raw material winding drum and the material receiving winding drum can be realized.

[0046] A waste collection structure is arranged below the cutting knife 5. The waste collection structure realizes the synchronous collection of waste during the slitting process by the moving supporting plate 19 and the baffle 20 approaching the cutting knife 5. The waste collection structure includes a lower base 17, which is arranged parallel to the upper base 1 below. The lower base 17 and the upper base 1 are fixedly connected by support legs. An electric push rod 18 is fixedly embedded on the surface of the lower base 17. The output end of the electric push rod 18 is fixed with a supporting plate 19. The supporting plate 19 is of a C-shaped structure. Baffles 20 are respectively rotatably connected to both side surfaces of the supporting plate 19. The supporting plate 19 and the two side baffles 20 form an open box-shaped structure. The box-shaped structure is aligned with the square through hole on the surface of the upper base 1. A driving roller 21 is rotatably installed on the side surface of the supporting plate 19 through a bracket. The driving roller 21 is located between the cutting knife 5 and the material receiving structure.

[0047] As Figure 4 and Figure 5 shown in the figure, after the raw material winding drum and the material receiving winding drum are installed, the electric push rod 18 is started. The electric push rod 18 drives the supporting plate 19 to move upward through the square through hole on the surface of the upper base 1 and approach the cutting knife 5. When the supporting plate 19 is moving, the baffles 20 on both side surfaces of the supporting plate 19 are squeezed by the inner wall of the square through hole, so that the supporting plate 19 and the two side baffles 20 together form a box structure. The box structure is used to synchronously collect the waste generated during the slitting process by the cutting knife 5. After the slitting of the device is completed, the electric push rod 18 is started again. The electric push rod 18 drives the supporting plate 19 to move downward. When the supporting plate 19 and the baffle 20 move downward synchronously, the lower part of the baffle 20 loses the acting force of the inner wall of the square through hole, so that the baffle 20 rotates on both sides of the supporting plate 19, exposing both sides of the box structure, which is convenient for centralized collection of the waste collected in the box structure.

[0048] A limiting structure is provided between the cutting knife 5 and the driving roller 21. The limiting structure preliminarily limits the lithium battery raw material coil through the first pushing roller 22 and the second pushing roller 23, facilitating subsequent contact and slitting of the raw material with the cutting knife 5 through the movement of the driving roller 21. The limiting structure includes the first pushing roller 22. The inside of the first pushing roller 22 is hollow. A counterweight block is arranged on the inner bottom surface of the first pushing roller 22. A clamping block is arranged at one end of the first pushing roller 22. A connecting rod 24 is fixed to the other end of the first pushing roller 22. The surface of the connecting rod 24 slidably penetrates through the surfaces of the second inner side plate 6 and the second outer side plate 7. A spring 28 is arranged on the outer surface of the connecting rod 24. One end of the spring 28 is fixed to the surface of the connecting rod 24, and the other end of the spring 28 is fixedly connected to the surface of the second inner side plate 6. One end of the surface of the connecting rod 24 is fixedly connected to one end of a connecting rope 25, and the other end of the connecting rope 25 is fixedly connected to the lower surface of the supporting plate 19. The clamping block on the surface of the first pushing roller 22 is in snap-fit with the clamping groove arranged on the surface of the second pushing roller 23. The inside of the second pushing roller 23 is hollow, and the same counterweight block is arranged inside the second pushing roller 23. Another set of connecting rod 24 and spring 28 are arranged at the other end of the second pushing roller 23. The connecting rod 24 slidably penetrates through the surfaces of the first inner side plate 2 and the first outer side plate 3. A spring 28 is arranged on the outer surface of the connecting rod 24. One end of the spring 28 is fixedly connected to the connecting rod 24, and the other end of the spring 28 is fixedly connected to the surface of the first inner side plate 2. One end of the surface of the connecting rod 24 is fixedly connected to one end of a connecting rope 25, and the other end of the connecting rope 25 is fixedly connected to the lower surface of the supporting plate 19;

[0049] As Figure 6 , Figure 7 and Figure 8 shown, when the raw material bypasses the upper surfaces of the first pushing roller 22 and the second pushing roller 23 and is connected to the receiving reel, the first pushing roller 22 and the second pushing roller 23 are engaged at this time. The first pushing roller 22 and the second pushing roller 23 are used to separate the raw material from the lower surface of the cutting knife 5. When starting the first electric push rod 18 to drive the supporting plate 19 to lift, the supporting plate 19 drives the driving roller 21 to lift synchronously. The driving roller 21 is used to lift the raw material upward, so that the raw material is away from the upper surfaces of the first pushing roller 22 and the second pushing roller 23 and close to the cutting knife 5. The upward thrust of the driving roller 21 makes the raw material fully contact the lower surface of the cutting knife 5. During this process, when the supporting plate 19 is lifted upward, one end of the connecting rope 25 will be pulled at the same time. The other end of the connecting rope 25 pulls the connecting rods 24 on both sides to slide. The connecting rods 24 on both sides drive the first pushing roller 22 and the second pushing roller 23 to slide to both sides respectively, stretching the spring 28. The first pushing roller 22 and the second pushing roller 23 that slide in the reverse direction lose the separating effect on the raw material and the cutting knife 5, so that the raw material is fully contacted with the cutting knife 5 under the action of the driving roller 21 for slitting.

[0050] Working principle: The raw material reel of the lithium battery is sleeved on the supporting roller 9 on one side of the cutting knife 5, and the finished product reel after slitting is sleeved on the supporting roller 9 on the other side. Start the second motor 10, and the output end thereof drives the supporting roller 9 to rotate, so as to realize the unwinding of the raw material from the raw material reel and the winding on the receiving reel. One end of the raw material sequentially bypasses the upper surface of the connecting roller 16, the lower surface of the cutting knife 5, then bypasses the upper surfaces of the first pushing roller 22 and the second pushing roller 23, and finally is connected to the receiving reel. Start the first electric push rod 18, and the first electric push rod 18 drives the supporting plate 19 to move upward through the square through hole of the upper base 1 close to the cutting knife 5. The box structure formed by the supporting plate 19 and the baffles 20 on both sides is used to collect the waste materials during the slitting process. When the supporting plate 19 is lifted, the supporting plate 19 drives the driving roller 21 to lift upward so that the raw material is in full contact with the lower surface of the cutting knife 5. At the same time, the supporting plate 19 pulls the connecting rope 25, and the other end of the connecting rope 25 pulls the first pushing roller 22 and the second pushing roller 23 to move to both sides, so that the first pushing roller 22 and the second pushing roller 23 lose the separating effect on the raw material and the cutting knife 5. Start the first motor 4, and the first motor 4 drives the cutting knife 5 to rotate. The rotating cutting knife 5 slits the raw material, and the finished product after slitting is wound on the receiving reel.

[0051] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
