Description

Technical Field

[0001] This utility model belongs to the technical field of copper foil production, and in particular relates to a copper foil cutting device. Background Technology

[0002] Copper foil production primarily employs an electrolytic process, comprising steps such as copper dissolution, electroplating, and surface treatment. The specific process flow is as follows: In the copper dissolution stage, copper material (such as copper wire) reacts with sulfuric acid and air to generate a copper sulfate solution, preparing for subsequent production. In the foil forming stage, in the electrolytic cell, the copper sulfate solution is subjected to direct current, causing cations to be reduced to metallic copper on the surface of the cathode roller, forming copper foil. The rotation of the cathode roller peels off the copper foil and performs surface treatment to prevent oxidation, ultimately winding it into a roll. Finally, the copper foil roll is released and cut into the required lengths.

[0003] Existing copper foil cutting equipment generally includes a release device and a cutting device. The release device releases the copper foil roll, and the cutting device cuts the copper foil. During cutting, the copper foil is transported into the cutting device. Because copper foil is ductile, it may be twisted and deformed locally during cutting, resulting in the cut copper foil being out of size or even scrapped. This requires stopping the machine for debugging, which reduces production efficiency. Utility Model Content

[0006] Furthermore, the cutting device includes a hydraulic telescopic rod fixedly mounted on the frame, a first blade fixedly mounted at the output end of the hydraulic telescopic rod, and a second blade fixedly mounted on the frame located below the first blade.

[0007] Furthermore, a first support body is fixedly installed on the upper end face of the frame, a hydraulic telescopic rod is fixedly installed on the upper end face of the first support body, an installation block is fixedly installed between the first blade and the output end of the hydraulic telescopic rod, and a pulling device is installed on the frame located on the rear side of the first blade.

The clamping roller is located in the corresponding vertical through slot.

[0009] Furthermore, a compression spring is fixedly installed above the roller shaft in the vertical groove on the rear side. The compression spring always drives the roller shaft on the rear side to move downward, so that the roller shaft on the rear side is located at the inner bottom wall of the vertical groove on the rear side.

[0010] Furthermore, a drive spring is fixedly installed between the mounting block and the front end of the lever.

[0011] Furthermore, a receiving block is fixedly provided on the rear side of the first blade, and the upper end surface of the receiving block is provided with a curved surface.

[0012] Furthermore, a connecting rod is fixedly installed between the two levers, and two pressure blocks are fixedly installed on the connecting rod. There are two drive springs, which are located between the mounting block and the corresponding pressure block, respectively.

[0013] Furthermore, a stacking platform fixed to the frame is provided on the rear side of the two clamping rollers.

[0014] Furthermore, the conveying device includes several transmission rollers arranged from left to right on the frame, a release device is arranged at the front end of the frame, and the copper foil on the release device extends backward and is connected to each transmission roller.

[0015] I. This utility model, by setting up a release device, a cutting device, a conveying device, and a pulling device, allows the following operation: When the conveying device is activated, it pulls the copper foil from the release device and transports it to the cutting device. The copper foil passes through the cutting device and is clamped by the pulling device. The pulling device pulls the copper foil backward, generating tension, which facilitates the cutting device in cutting the copper foil. The pulling device pulls the copper foil backward, causing it to be in a flat state, before the cutting device performs the cutting, thus improving the cutting quality and efficiency.

[0016] II. This utility model, by setting up clamping rollers, roller shafts, and levers, allows for the following process during cutting: A hydraulic telescopic rod pushes the mounting block and the first blade downwards. Simultaneously, the first blade drives the front end of the lever downwards, causing the lever to move the front clamping roller downwards along the front vertical groove. When the front clamping roller reaches the inner bottom wall of the front vertical groove, it stops moving downwards, while the first blade continues to move downwards. Simultaneously, it drives the front end of the lever to rotate downwards, causing the lever to rotate around the front roller shaft. This causes the rear end of the lever to push the rear roller shaft upwards within the rear vertical groove, resulting in a smaller and smaller gap between the two clamping rollers, thus clamping the copper foil between them. The rotation of the front clamping roller also has a winding effect on the copper foil, generating a backward pulling force. At this point, the first and second blades converge to cut the copper foil. Because the copper foil generates a backward pulling force during cutting, it is cut while completely flat, resulting in a better cutting effect. Attached Figure Description

[0026] Please see Figure 1-8 The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0027] The copper foil cutting device of this utility model includes a front release device 1 and a rear cutting device 2. A conveying device is provided between the release device 1 and the cutting device 2. The release device 1 is used to release copper foil 3, and the conveying device is used to convey the copper foil 3 released by the release device 1 to the cutting device 2 for cutting. The conveying device applies a pulling force to the copper foil 3 so that the copper foil 3 is released from the release device 1. At the same time, the conveying device has the function of correcting the position of the copper foil 3. The cutting device 2 cuts the copper foil 3. A pulling device 4 is provided on the rear side of the cutting device 2. The pulling device 4 is used to flatten the copper foil 3 before cutting to facilitate the cutting device 2 to cut the copper foil 3.

[0028] In use, the conveying device is activated, and the conveying device pulls out the copper foil 3 from the release device 1 and conveys it to the cutting device 2. The copper foil 3 passes through the cutting device 2 and is clamped by the pulling device 4. The pulling device 4 pulls the copper foil 3 backward to generate tension, which facilitates the cutting device 2 to cut the copper foil 3. The pulling device 4 pulls the copper foil 3 backward, so that the copper foil 3 is in a flat state, and then the cutting device 2 performs the cutting, which improves the cutting quality and efficiency.

[0029] In this embodiment, the cutting device 2 includes a hydraulic telescopic rod 5 fixedly mounted on the frame 7. A first blade 6 is fixedly mounted at the output end of the hydraulic telescopic rod 5, and a second blade 8 fixedly mounted on the frame 7 is located below the first blade 6. In use, the hydraulic telescopic rod 5 pushes the first blade 6 downward, so that the first blade 6 and the second blade 8 cooperate to cut the copper foil 3.

[0030] In this embodiment, a first support body 9 is fixedly installed on the upper end face of the frame 7, and a hydraulic telescopic rod 5 is fixedly installed on the upper end face of the first support body 9. An installation block 10 is fixedly installed between the first blade 6 and the output end of the hydraulic telescopic rod 5. A pulling device 4 is installed on the frame 7 located behind the first blade 6. When the installation block 10 moves downward, it drives the pulling device 4 to move, so that the pulling device 4 clamps the copper foil 3 and pulls the copper foil 3 backward. Then the first blade 6 and the second blade 8 come together to cut the copper foil 3.

[0031] In this embodiment, the pulling device 4 includes two clamping rollers 11, each clamping roller 11 having a roller shaft 12 fixedly installed inside. A lever 13 is vertically fixed inside the roller shaft 12 of the front clamping roller 11, with the rear end of the lever 13 extending below the roller shaft 12 of the rear clamping roller 11. A side block 14 corresponding to the clamping roller 11 is fixedly installed on the frame 7. Two vertical through slots 15 are formed in the side block 14 along the vertical direction, and the clamping roller 11 is located within the corresponding vertical through slot 15. During this process, the conveying device continuously pulls out copper foil 3 from the release device 1 and feeds it between the first blade 6 and the second blade 8. The copper foil 3 also enters between the two clamping rollers 11. When cutting, the hydraulic telescopic rod 5 pushes the mounting block 10 and the first blade 6 downwards. Simultaneously, the mounting block 10 drives the front end of the lever 13 downwards, causing the lever 13 to move the front clamping roller 11 downwards along the front vertical groove 15. When the front clamping roller 11 moves to the front vertical groove... At the inner bottom wall of 15, the front clamping roller 11 stops moving downwards, while the mounting block 10 continues to move downwards, driving the first blade 6 downwards and simultaneously driving the front end of the lever 13 to rotate downwards. This causes the lever 13 to rotate around the front roller shaft 12, causing the rear end of the lever 13 to push the rear roller shaft 12 upwards, moving it upwards within the rear vertical through groove 15. This reduces the distance between the two clamping rollers 11, clamping the copper foil 3 between them. Simultaneously, the rotation of the front clamping roller 11 has a winding effect on the copper foil 3, causing the copper foil 3 to generate a backward pulling force. At this time, the first blade 6 and the second blade 8 converge to cut the copper foil 3. Because the copper foil 3 generates a backward pulling force during cutting, it is in a flattened state, resulting in a better cutting effect. The cut copper foil 3 slides out from between the two clamping rollers 11 and is discharged, while a new copper foil 3 extends from between the first blade 6 and the second blade 8 and re-enters between the two clamping rollers 11 for the next cut.

[0032] In this embodiment, a compression spring 16 is fixedly installed above the roller 12 in the vertical groove 15 on the rear side. The compression spring 16 always drives the roller 12 on the rear side to move downward, so that the roller 12 on the rear side is at the inner bottom wall of the vertical groove 15 on the rear side. The mounting block 10 moves downward to push the lever 13 to drive the roller 12 on the front side to move downward. When the roller 12 on the front side moves downward to the inner bottom wall of the vertical groove 15 on the front side, the lever 13 rotates. The rear end of the lever 13 pushes the roller 12 on the rear side upward, thereby driving the clamping roller 11 on the rear side to move upward. When the roller 12 moves upward, it overcomes the force of the compression spring 16.

[0033] In this embodiment, a drive spring 17 is fixedly provided between the front end of the mounting block 10 and the lever 13. When the mounting block 10 moves downward, the mounting block 10 compresses the drive spring 17, and the drive spring 17 transmits force to the front end of the lever 13, causing the lever 13 to move downward or the front end of the lever 13 to rotate downward.

[0034] In this embodiment, a receiving block 18 is fixedly provided on the rear side of the first blade 6. The upper end surface of the receiving block 18 is provided with a curved surface. When the copper foil 3 is cut, the cut copper foil 3 slides down along the curved surface and slides out between the two clamping rollers 11 to complete the discharge.

[0035] In this embodiment, a connecting rod 19 is fixedly arranged between the two levers 13, and two pressure blocks 20 are fixedly arranged on the connecting rod 19. There are two drive springs 17, which are located between the mounting block 10 and the corresponding pressure block 20, respectively.

[0036] In this embodiment, a stacking platform 21 fixedly mounted to the frame 7 is provided on the rear side of the two clamping rollers 11, and the cut copper foils 3 are all stacked on the stacking platform 21.

[0037] In this embodiment, the conveying device includes several transmission rollers 22 arranged from left to right on the frame 7. The release device 1 is located at the front end of the frame 7. The copper foil 3 on the release device 1 extends backward and is connected to each transmission roller 22. A second support body 23 is fixedly arranged on the upper end face of the frame 7. Two pressure rollers 24 are rotatably connected inside the first support body 9 and the second support body 23. A motor 25 is fixedly arranged on the left side face of the first support body 9 and the second support body 23. The output shaft of the motor 25 is fixedly arranged with the corresponding pressure roller 24. In use, the copper foil 3 is located between the two pressure rollers 24 in the second support body 23 and simultaneously between the two pressure rollers 24 in the first support body 9. The motor 25 rotates and drives the pressure rollers 24 to rotate. The pressure rollers 24 drive the other pressure roller 24 to rotate through the gear 26, so that the two pressure rollers 24 drive the copper foil 3 to move backward. At the same time, the release device 1 releases the corresponding amount of copper foil 3.

[0038] In this embodiment, the release device 1 includes a spool that is rotatably connected to the frame 7 and located at the left end of the frame 7. The copper foil 3 is wound onto the spool. The motor 25 drives the pressure roller 24 to rotate, so that when the pressure roller 24 moves the copper foil 3 backward, the spool rotates and releases the copper foil 3 wound onto the spool.

[0039] The working principle of this utility model is as follows: In use, the motor 25 rotates, driving the pressure roller 24 to rotate. The two pressure rollers 24 rotate simultaneously, causing the copper foil 3 to move backward. When the copper foil 3 moves, it drives each transmission roller 22 to rotate. At the same time, the reel is forced to rotate, releasing the copper foil 3 from the reel. When the copper foil 3 moves backward a set distance, the hydraulic telescopic rod 5 pushes the mounting block 10 and the first blade 6 to move downward. At the same time, the mounting block 10 drives the front end of the lever 13 to move downward, causing the lever 13 to drive the front clamping roller 11 to move downward along the front vertical through groove 15. When the front clamping roller 11 moves to the inner bottom wall of the front vertical through groove 15, the front clamping roller 11 stops moving downward. As the mounting block 10 continues to move downwards, it drives the first blade 6 downwards and simultaneously drives the front end of the lever 13 to rotate downwards, causing the lever 13 to rotate around the front roller 12. This causes the rear end of the lever 13 to push the rear roller 12 upwards, moving it upwards within the rear vertical through groove 15. This results in the gap between the two clamping rollers 11 becoming smaller and smaller, clamping the copper foil 3 between the two clamping rollers 11. At the same time, the rotation of the front clamping roller 11 has a winding effect on the copper foil 3, causing the copper foil 3 to generate a backward pulling force. At this time, the first blade 6 and the second blade 8 converge to cut the copper foil 3. Because the copper foil 3 generates a backward pulling force during cutting, the cutting effect is better.
