Abstract
Description
Technical Field
[0001] This utility model relates to the field of foil cutting machine technology, specifically to a capacitor production foil cutting machine with a winding structure. Background Technology
[0002] In the capacitor production process, the foil cutting machine is one of the key pieces of equipment. Its function is to cut the rolled metal foil strips according to the process requirements for use in subsequent processes.
[0003] During the cutting process, a motor-driven roller conveys the rolled metal foil to the cutting area at a uniform speed. Then, a cutting blade slides along the metal foil to cut it. After cutting, a typical foil cutting machine usually stacks and collects the foil sheets. This collection method can easily cause the foil sheets to rub against each other, wrinkle, or even scratch, affecting the quality of the foil sheets. Moreover, in subsequent use, the stacked foil sheets need to be separated manually one by one, which is cumbersome and inefficient. Some foil cutting machines may have a winding structure, but changing the winding shaft is complicated and requires a long downtime, reducing production efficiency. Therefore, a capacitor-based foil cutting machine with a winding structure is needed. Utility Model Content
[0004] The purpose of this invention is to provide a capacitor production foil cutting machine with a winding structure to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a capacitor production foil cutting machine with a winding structure, comprising a foil cutting machine body, a feeding roller, metal foil, and a winding roller. A feeding roller is mounted on one side of the foil cutting machine body via a first bracket, and the feeding roller winds up the metal foil. A second bracket is mounted on the side of the foil cutting machine body away from the feeding roller, and a winding roller is mounted inside the second bracket via a shaft. A laser cutting head is mounted at the center of the foil cutting machine body via a third bracket. A first roller groove and a second roller groove are respectively mounted on both sides inside the second bracket. The two ends of the shaft are respectively connected to the first roller groove and the second roller groove. A second drive motor for driving the first roller groove to rotate is fixed on one side of the second bracket. A housing is mounted on one side inside the second bracket, and actuating elements are uniformly mounted inside the housing via return springs. The actuating elements are connected to the second roller groove.
[0006] Preferably, a first drive motor is fixed on one side of the first bracket, and the output end of the first drive motor is connected to the feeding roller.
[0007] Preferably, a fourth support is provided at the top of the first support, and a cleaning brush is uniformly provided at the bottom of the fourth support through a buffer cylinder.
[0008] Preferably, the bristles of the cleaning brush are in contact with the surface of the metal foil, and the cleaning brush is made of sponge bristles.
[0009] Preferably, the interior of each buffer cylinder is equipped with a pressure-bearing component via a rubber column, and the bottom end of each pressure-bearing component is connected to a cleaning brush.
[0010] Preferably, the top of the third bracket is provided with an electric slide rail, and the top of the laser cutting head is connected to the electric slide rail via a slider.
[0011] Preferably, one end of the shaft is embedded in the first roller groove, and a rubber pad is provided inside the first roller groove.
[0012] Preferably, the inner wall of the second roller groove is uniformly provided with guide balls, and the guide balls are in contact with the surface of the shaft away from the first roller groove.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This capacitor production foil cutting machine with a winding structure is equipped with a foil cutting machine body, a feeding roller, metal foil, an electric slide rail, a laser cutting head, a winding roller, a second drive motor, a first roller groove, a second roller groove, a drive shaft, a housing, a return spring, a toggle piece, a connecting shaft, and guide balls. The metal foil is fed out by the feeding roller, and one end passes through the foil cutting machine body and connects to the winding roller. The second drive motor drives the winding roller to rotate, winding the metal foil cut by the laser cutting head onto the winding roller, making it less likely for scratches to occur between the metal foils due to friction. After winding is completed, the toggle piece is pulled to one side, which squeezes the return spring on one side, thereby separating the second roller groove from the shaft of the winding roller. Then the winding roller is removed and another set of winding rollers is replaced to perform the metal foil winding work. The winding roller can be disassembled without tools, greatly shortening the roll change time and improving production efficiency. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0022] Please see Figure 1-5 The present invention provides an embodiment of a capacitor production foil cutting machine with a winding structure, comprising a foil cutting machine body 1, a feeding roller 2, a metal foil 3 and a winding roller 8. The feeding roller 2 is provided on one side of the foil cutting machine body 1 through a first bracket 4, and the feeding roller 2 winds up the metal foil 3. A first drive motor 20 is fixed on one side of the first bracket 4, and the output end of the first drive motor 20 is connected to the feeding roller 2.
[0023] The feeding roller 2 starts to rotate under the control of the first drive motor 20, conveying the wound metal foil 3 towards the foil cutting machine body 1;
[0024] The top of the first bracket 4 is provided with a fourth bracket 5, and the bottom of the fourth bracket 5 is provided with cleaning brushes 22 evenly through the buffer tube 21.
[0025] Before the metal foil 3 enters the main body 1 of the foil cutting machine after being unwound, the cleaning brush 22 can promptly remove dust, debris and other impurities attached to the surface of the metal foil 3, preventing these impurities from affecting the cutting accuracy.
[0026] The bristles of the cleaning brush 22 are in contact with the surface of the metal foil 3. The cleaning brush 22 is made of sponge bristles, which are soft in texture. When cleaning impurities on the surface of the metal foil 3, it is not easy to cause physical damage such as scratches or wear to the surface of the metal foil 3. It can also effectively absorb dust and tiny particles to ensure the cleaning effect of the metal foil 3.
[0027] The interior of each buffer cylinder 21 is equipped with a pressure-bearing component 24 via a rubber column 23, and the bottom end of each pressure-bearing component 24 is connected to the cleaning brush 22.
[0028] The rubber column 23 has good elasticity and cushioning performance. It can automatically adjust the pressure of the cleaning brush 22 on the metal foil 3 according to the undulation of the metal foil 3 surface, so that the cleaning brush 22 can closely adhere to the surface of the metal foil 3 to ensure the cleaning effect, and will not damage the metal foil 3 due to excessive pressure.
[0029] A second support 9 is provided on the side of the foil cutting machine body 1 away from the feeding roller 2, and a winding roller 8 is provided inside the second support 9 through the shaft 12;
[0030] A laser cutting head 18 is installed in the center of the main body 1 of the foil cutting machine via a third bracket 6. The first roller groove 10 and the second roller groove 13 are respectively installed on both sides inside the second bracket 9. The two ends of the shaft 12 are connected to the first roller groove 10 and the second roller groove 13 respectively.
[0031] A second drive motor 11 is fixed on one side of the second bracket 9 to drive the first roller groove 10 to rotate, and pulls one end of the metal foil 3 to connect with the take-up roller 8. The take-up roller 8 is connected to the first roller groove 10 and the second roller groove 13 through the shaft 12. The second drive motor 11 drives the first roller groove 10 to rotate, and drives the take-up roller 8 to rotate synchronously.
[0032] The top of the third support 6 is equipped with an electric slide rail 19. The top of the laser cutting head 18 is connected to the electric slide rail 19 via a slider. The laser cutting head 18 uses a high-energy laser beam to melt or vaporize the metal foil 3 and moves under the drive of the electric slide rail 19, thereby cutting the metal foil 3 with high precision. The cutting edge is smooth and the precision is high. The cut metal foil 3 is wound up by the winding roller 8, so that the metal foil 3 is not easy to be scratched by friction.
[0033] A housing 14 is provided on one side inside the second bracket 9, and a toggle member 16 is uniformly provided inside the housing 14 through a reset spring 15. The toggle member 16 is connected to the second roller groove 13.
[0034] After winding is completed, the operator pulls the actuating part 16 to one side to compress the return spring 15, so that the second roller groove 13 is separated from the shaft 12. Then, the winding roller 8 is pulled to one side so that its other end is separated from the first roller groove 10. The winding roller 8 that has been wound up with metal foil 3 is removed and replaced with an empty winding roller 8.
[0035] One end of the shaft 12 is embedded in the first roller groove 10, and a rubber pad 7 is provided inside the first roller groove 10;
[0036] The inner wall of the second roller groove 13 is uniformly provided with guide balls 17, and the guide balls 17 are in contact with the surface of the shaft 12 away from the first roller groove 10.
[0037] The shafts 12 at both ends of the new set of take-up rollers 8 are respectively embedded in the first roller groove 10 and the second roller groove 13. A rubber pad 7 is provided in the first roller groove 10 so that it bites tightly with one end of the shaft 12, which facilitates the rotation of the take-up roller 8.
[0038] The other end of the shaft 12 is connected to the guide ball 17 in the second roller groove 13 to facilitate the rotation of the guide. Then, the actuating part 16 is released, the reset spring 15 pushes the second roller groove 13 to reset, and the new take-up roller 8 is re-clamped. The take-up roller 8 can be quickly disassembled and installed without tools, which greatly shortens the roll change time and helps to improve production efficiency.
[0039] The specific models and specifications of the first drive motor 20, the second drive motor 11, and the electric slide rail 19 need to be determined by selection calculation based on the specifications and parameters of the device. The selection calculation method is existing technology, so it will not be described in detail here.
[0040] Working principle: In this embodiment, the unloading roller 2 rotates under the control of the first drive motor 20, conveying the wound metal foil 3 towards the main body 1 of the foil cutting machine. The sponge bristles on the cleaning brush 22 located at the bottom of the fourth bracket 5 contact the surface of the metal foil 3 to remove dust and debris during the unwinding process. One end of the metal foil 3 is pulled to connect with the winding roller 8. The winding roller 8 is connected to the first roller groove 10 and the second roller groove 13 through the shaft 12. The second drive motor 11 drives the first roller groove 10 to rotate, causing the winding roller 8 to rotate synchronously. The laser cutting head 18 performs high-precision cutting of the metal foil 3 under the drive of the electric slide rail 19. The cut metal foil 3 is wound up by the winding roller 8. After winding is completed, the operator pulls the actuating part 16 to one side to press... The return spring 15 is retracted to separate the second roller groove 13 from the shaft 12. Then, the take-up roller 8 is pulled to one side so that its other end is disengaged from the first roller groove 10. The take-up roller 8 with the metal foil 3 is removed and replaced with an empty take-up roller 8. The shafts 12 at both ends of the empty take-up roller 8 are respectively embedded in the first roller groove 10 and the second roller groove 13. A rubber pad 7 is provided in the first roller groove 10 so that it bites tightly with one end of the shaft 12, which facilitates the rotation of the take-up roller 8. The other end of the shaft 12 is connected to the guide ball 17 in the second roller groove 13 to facilitate the rotation. Then, the actuating element 16 is released and the return spring 15 pushes the second roller groove 13 to reset, and the new take-up roller 8 is re-clamped. The take-up roller 8 can be quickly disassembled and installed without tools, which greatly shortens the roll change time and helps to improve production efficiency.
