A capacitor is an electronic component capable of storing electric charge, and the aluminum foil is a piece of aluminum foil with special properties. By cooperating with electrolytes, dielectric materials, etc., the charge storage and release functions of the capacitor are realized.

[0031] Embodiment:

[0032] Please refer to Figures 1-8 , the present invention provides a technical solution: a capacitor aluminum foil cutting device with a rotating tension wheel anti-slip structure, including:

[0033] A loading part 1, the loading part 1 includes a workbench 11, the workbench 11 is slidably connected with a sliding seat 12 through a slide rail groove opened in its interior, one side of the sliding seat 12 is rotatably connected with a rotating shaft 13, and a tightening part 14 for placing an external aluminum foil coil is arranged on the circumferential outer surface of the rotating shaft 13, a driving part is arranged inside the sliding seat 12, and the driving part is in transmission connection with the rotating shaft 13;

[0035] Among them, the expansion fastener 14 includes a hollow sleeve rod 141. The inner circumferential wall of the hollow sleeve rod 141 is slidably connected to the outer circumferential surface of the rotating shaft 13. A ring plate 142 that fits against the outer circumferential surface of the rotating shaft 13 is fixedly connected to one side of the hollow sleeve rod 141 close to the sliding seat 12. The hollow sleeve rod 141 is rotatably connected to a pressing plate 144 through a connecting rod 143 provided on its outer circumferential surface, and one side of the pressing plate 144 close to the sliding seat 12 is slidably connected to the inside of the ring plate 142;

[0036] Among them, the workbench 11 is slidably connected to a lifting shaft rod 15 through a guide rod fixed on its upper surface, and a tension pulley 151 is sleeved on the outer circumferential surface of the lifting shaft rod 15. A tension adjusting member 16 for adjusting the height of the tension pulley 151 is provided on one side of the sliding seat 12 away from the rotating shaft 13. There are two lifting shaft rods 15 and they are symmetrically distributed with the tension pulley 151 as the center.

[0037] Below the cutting roller 21, there is a material receiving roller 22 rotatably connected to the inside of the side plate. On one side of the cutting roller 21 close to the tension pulley 151, there is a lower roller shaft 23 rotatably connected to the inside of the side plate. Above the lower roller shaft 23, there is an upper roller shaft 24 slidably connected to the inside of the side plate.

[0038] There are two sliding seats 12 and they are symmetrically distributed with the workbench 11 as the center. A magnetic ring plate 145 is fixedly connected to one side of the ring plate 142 away from the sliding seat 12. An arc-shaped rubber block is fixedly connected to one side of the pressing plate 144 away from the hollow sleeve rod 141. There are three pressing plates 144 and they are circumferentially arrayed with the hollow sleeve rod 141 as the center.

[0039] The tension adjusting member 16 includes a rotating rod 161. The middle part of the rotating rod 161 is rotatably connected to one side of the sliding seat 12 away from the rotating shaft 13. A linkage frame 162 is fixedly connected to one end of the rotating rod 161 close to the cutting blade 211. The internal connection part of the linkage frame 162 is designed with an arc angle. A limiting block 163 is fixedly connected to one side of the sliding seat 12 close to the rotating rod 161. An L-shaped rod 164 is slidably connected inside the limiting block 163. The top end of the L-shaped rod 164 is fixedly connected to a limiting frame 165.

[0040] The inside of the limiting frame 165 is designed with an arc shape, and the inner surface of the limiting frame 165 fits against the outer surface of the rotating rod 161. The inside of the linkage frame 162 fits against the outer circumferential surface of the lifting shaft rod 15.

[0041] The interior of the sliding seat 12 is provided with a notch. The outer end of the L-shaped rod 164 away from the limiting frame 165 penetrates through the sliding seat 12 and is fixedly connected with a connecting plate 17. One side of the connecting plate 17 away from the sliding seat 12 is fixedly connected with a long rod 171. The long rod 171 is rotationally connected with a positioning wheel 172 through a ball arranged on its circumferential outer surface. One side of the connecting plate 17 close to the long rod 171 is fixedly connected with a short rod 173. The long rod 171 and the short rod 173 are in the same horizontal plane, and the long rod 171 and the short rod 173 are symmetrically distributed with the rotating shaft 13 as the center.

[0042] The upper surface of the workbench 11 is fixedly connected with a bracket 111. The upper surface of the bracket 111 is provided with an arc-shaped groove, and the inner wall of the arc-shaped groove is fitted with the outer surface of the positioning wheel 172. The outer end of the positioning wheel 172 away from the connecting plate 17 adopts an arc surface design, and the outer end of the short rod 173 away from the connecting plate 17 adopts a small arc surface design.

[0043] The process of loading the aluminum foil roll:

[0044] In practical applications, in the initial state, the slide rail groove is controlled by the driving base on the side of the workbench 11, and the two sliding seats 12 sliding inside it are simultaneously moved to the side away from the bracket 111, that is, the distance between the two sliding seats 12 increases. The expansion member 14, the tension adjusting member 16, and the rotating shaft 13 move outward together. At this time, the positioning wheel 172 is located above its movable range along with the connecting plate 17 and the L-shaped rod 164. Use an external hoisting device to move the aluminum foil roll from above to the upper part of the loading part 1, and vertically lower the aluminum foil roll from the middle of the two sliding seats 12. When the lower surface of the aluminum foil roll comes into contact with the outer surfaces of the two positioning wheels 172, then slowly move it down until the central axis of the aluminum foil roll is approximately in the same position as the central axis of the rotating shaft 13.

[0045] During the downward movement of the aluminum foil roll, the lower surface of the aluminum foil roll comes into contact with the outer surface of the positioning wheel 172. After the aluminum foil roll contacts the positioning wheel 172, it drives the connecting plate 17, the L-shaped rod 164, and the limiting frame 165 (restricted by the limiting block 163) to move vertically downward (the outer surface of the positioning wheel 172 is always in contact with the outer surface of the aluminum foil roll). During this process, the rotating rod 161 drives the linkage frame 162 to tilt upward using the lever principle, and the tension wheel 151 and the lifting shaft rod 15 move vertically upward on the outer surface of the guide rail rod under the influence of the linkage frame 162.

[0046] When the central axis of the aluminum foil roll is roughly at the same position as the central axis of the rotating shaft 13, the slide seats 12 on both sides are driven to move inward simultaneously through the slide rails inside the workbench 11, and the distance between the two slide seats 12 gradually decreases. During the movement, the magnetic ring plates 145 on both sides approach each other until they are attracted to each other. As the slide seats 12 continue to move, the hollow sleeve rods 141 and the magnetic ring plates 145 move simultaneously on the outer surface of the rotating shaft 13 towards the annular plate 142. Since one end of the pressure-receiving plate 144 away from the magnetic ring plate 145 is slidably connected to the inside of the annular plate 142 and the pressure-receiving plate 144 is parallel to the rotating shaft 13, when the hollow sleeve rod 141 slides towards the annular plate 142, the pressure-receiving plate 144 is unfolded outward through the shifting groove inside the annular plate 142 under the action of the connecting rod 143.

[0047] An arc-shaped rubber block is fixedly connected to the outer surface of the pressure-receiving plate 144 away from the hollow sleeve rod 141. As the three pressure-receiving plates 144 are unfolded outward simultaneously, their outer surfaces will fit against the inner surface of the drum of the aluminum foil roll. When the arc-shaped rubber block undergoes elastic deformation, the central axis of the rotating shaft 13 is completely aligned with the central axis of the aluminum foil roll, and the aluminum foil roll is also stably placed through the expansion member 14. At this time, the pressure-receiving plate 144 can no longer be unfolded outward, the slide seats 12 remain in this position and stop moving further, and the external hoisting equipment also withdraws.

[0048] When the diameter of the aluminum foil roll material is the maximum diameter adapted by the expansion member 14 and the tension adjusting member 16, the aluminum foil roll presses the positioning wheel 172 downward. At this time, the bracket 111 can prevent the positioning wheel 172 and the long rod 171 from being damaged due to impact.

[0049] During the process of the slide seats 12 moving towards each other, the long rod 171 on one side approaches the short rod 173 on the other side. The outer surface of the long rod 171 is rotatably connected to the positioning wheel 172. The length of the long rod 171 in the same group is less than the length of the inner surface of the circumference of the positioning wheel 172. The outer end of the short rod 173 is arc-shaped and has a smaller diameter at the outer end. The outer surface of the positioning wheel 172 away from the connecting plate 17 on the same side is also designed with an arc surface. When the long rod 171 and the short rod 173 approach each other, the short rod 173 can smoothly enter the inside of the positioning wheel 172 to form a whole, improving the stability.

[0050] The process of cutting the aluminum foil roll:

[0051] After the aluminum foil roll is loaded, it is unpacked, and the starting end of the aluminum foil is bypassed above the tension wheel 151, passed through between the upper roller 24 and the lower roller 23, adhered to and bypassed the upper surface of the cutting roller 21 and fixed on the outer surface of the winding roller 22. When the aluminum foil passes through the cutting roller 21, its outer surface is penetrated by the cutting blade 211 and cut into multiple segments. After preparation, the driving device inside the sliding seat 12 is started to drive the rotating shaft 13 to rotate. The annular plate 142 sleeved on the outer surface of the rotating shaft 13 rotates with it, and the aluminum foil roll also rotates together through the expansion member 14. During this process, the winding roller 22 also rotates to collect the cut aluminum foil.

[0052] The outer diameter of the initial aluminum foil roll is relatively large, and the length of the aluminum foil output by one rotation of the rotating shaft 13 is relatively long. In order to prevent the aluminum foil from wrinkling, skewing, etc., it is necessary to increase the tension. As the cutting roller 21 and the winding roller 22 continuously separate and collect, the raw material of the aluminum foil roll is continuously output, and the outer diameter of the aluminum foil roll gradually decreases, that is, the length of the aluminum foil output after one rotation of the rotating shaft 13 becomes shorter. At this time, in order to prevent the aluminum foil from being deformed or broken due to excessive tensile force of the aluminum foil, it is necessary to reduce the tension of the aluminum foil.

[0053] In the initial state, the positioning wheel 172 is at the bottom end of the aluminum foil roll and is in close contact with the circumferential lower surface of the aluminum foil roll. The inner surface of the linkage frame 162 at the outer end of the rotating rod 161 is in contact with the circumferential outer surface of the tension wheel 151. Since the tension wheel 151 has a certain weight, the outer end of the lifting shaft rod 15 is inside the linkage frame 162, and the center of gravity of the tension wheel 151 presses inside the linkage frame 162. The middle position of the rotating rod 161 is rotatably connected to the outside of the sliding seat 12, acting as a fulcrum, which will drive the other end of the rotating rod 161 to drive the limiting frame 165 to pry upward, giving an upward force to the L-shaped rod 164 inside the limiting block 163, increasing the contact between the positioning wheel 172 below the L-shaped rod 164 and the outer surface of the aluminum foil roll, and increasing the friction between the positioning wheel 172 and the outer surface of the aluminum foil roll.

[0054] As the aluminum foil is continuously released, the diameter of the aluminum foil roll gradually decreases, and the tension and position state of the outermost layer of the aluminum foil are also constantly changing. By continuously adhering to the outer surface of the aluminum foil roll, the positioning wheel 172 can continuously apply pressure and friction, adapt to this change, and always maintain the restraint on the outermost layer of the aluminum foil. Especially when the unwinding speed is relatively fast or the winding of the aluminum foil roll is relatively loose, the positioning wheel 172 can prevent the outermost layer of the aluminum foil from slipping due to centrifugal force or uneven internal tension, improving the stability and ensuring the cutting quality.

[0055] As the number of rotations of the rotating shaft 13 increases, the length of the aluminum foil roll output per rotation gradually decreases, and the tension needs to be reduced to avoid stretching deformation, fracture, etc. The outer diameter of the aluminum foil roll begins to gradually become smaller. The tension wheel 151 always has a downward gravity. Taking the middle part of the rotating rod 161 as the fulcrum, the rotating rod 161 is affected by the gravity of the tension wheel 151, and drives the outer circumferential surface of the positioning wheel 172 to always fit against the lower outer surface of the aluminum foil roll through the L-shaped rod 164. After the outer diameter of the aluminum foil roll decreases, the positioning wheel 172 gradually moves vertically upward, and the L-shaped rod 164 and the limiting frame 165 move vertically upward together. The inner part of the limiting frame 165 is designed with a curved surface, and the outer surface of the rotating rod 161 can always fit against the inner part of the limiting frame 165 and move in a smooth state. After the limiting frame 165 moves upward, the linkage frame 162 at the other end of the rotating rod 161 will rotate and move downward accordingly, and the lifting shaft rod 15 that fits against the inside of the linkage frame 162 will also move vertically downward.

[0056] During this process, the wrap angle between the tension wheel 151 and the aluminum foil bag decreases, the friction force decreases, and the tension also decreases accordingly. The path of the aluminum foil around the tension wheel 151 to reach between the upper roller shaft 24 and the lower roller shaft 23 becomes shorter, which can match the gradually decreasing aluminum foil output length of the rotating shaft 13, reduce the tension of the aluminum foil, and avoid the situation of aluminum foil fracture caused by excessive tension.

[0057] As the rotating shaft 13 rotates continuously and uniformly, the distance of the aluminum foil output per rotation will become shorter and shorter. The positioning wheel 172 is affected by the gravity of the tension wheel 151 and always fits against the outer surface of the aluminum foil roll. The outer diameter of the aluminum foil roll gradually decreases, the height of the positioning wheel 172 gradually rises, the height of the tension wheel 151 and the lifting shaft rod 15 gradually decreases, the wrap angle between the tension wheel 151 and the external aluminum foil gradually decreases, the path of the aluminum foil from the outer surface of the aluminum foil roll to the lower roller shaft 23 gradually becomes flat, and the path distance of the aluminum foil from the rotating shaft 13 to the cutting roller 21 gradually becomes shorter, adapting to the tension required for the aluminum foil roll with a gradually decreasing outer diameter.

[0058] The process of discharging the aluminum foil roll:

[0059] When all the aluminum foil rolls are cut, at this time, the positioning wheel 172, the L-shaped rod 164, and the limiting frame 165 are all at the highest points within their movable ranges through sliding connection with the inside of the limiting block 163; correspondingly, the tension wheel 151 is at the lowest point within its movable range through sliding connection with the outer surface of the guide rail rod through the lifting shaft rod 15. At this time, the side of the rotating rod 161 close to the linkage frame 162 is lower and in an inclined state.

[0060] By controlling the sliding seats 12 on both sides through the driving base to move towards the side away from the bracket 111, the tension adjusting member 16, the expanding member 14 and the rotating shaft 13 will move synchronously. When the expanding members 14 on both sides move away from each other following the rotating shaft 13, the magnetic ring plates 145 at their outer ends still maintain magnetic attraction, driving the hollow sleeve rod 141 to remain stationary and generating relative displacement with the rotating shaft 13 and the annular plate 142. The distance between the magnetic ring plate 145 and the annular plate 142 increases, which will drive the pressure-receiving plates 144 to approach each other towards the circumferential outer surface of the hollow sleeve rod 141 under the action of the connecting rod 143. The pressure-receiving plates 144 complete the contraction and reset action under the magnetic attraction of the magnetic ring plate 145 and the gravity of the remaining aluminum foil reel.

[0061] At this time, the inner diameter of the aluminum foil roll is larger than the diameter enclosed by the three pressure-receiving plates 144 in the expanding member 14. Since the positioning wheel 172 is always affected by the tension wheel 151 and given an upward force, it will drive the remaining aluminum foil roll to move upward, and the rotating shaft 13 moves towards each other along with the sliding seat 12. After the rotating shaft 13 is withdrawn, the aluminum foil roll is above the two positioning wheels 172, and the circumferential outer surface thereof is tangent to the circumferential outer surfaces of the two positioning wheels 172. After removing the remaining aluminum foil reel, a new aluminum foil roll is put in again through an external hoisting robotic arm and continuously cut by the cutting blade 211.

[0062] In summary, during the feeding and cutting process of the aluminum foil roll, the following advantages are achieved:

[0063] Advantage 1: During feeding, by moving the sliding seats 12 on both sides closer to each other, the expanding members 14 on both sides also move closer to each other. After the two magnetic ring plates 145 are closely attached, they can drive the pressure-receiving plates 144 to expand outwards, fixing the external aluminum foil roll from the inside, making the central axis of the aluminum foil roll coincide with the central axis of the rotating shaft 13, ensuring the stability of transportation, avoiding the situation where the friction forces are different due to the inconsistent distances between different parts of the aluminum foil roll and the rotating shaft 13, making the tension of the aluminum foil uniform when it unfolds from the roll, improving the cutting accuracy. When the rotating shaft 13 rotates, the pressure-receiving plates 144 will also move outwards under the action of centrifugal force, further enhancing the fixation of the aluminum foil roll.

[0064] Advantage 2: During discharging, the sliding seats 12 on both sides move away from each other. Among them, when the expanding members 14 move away from each other, the magnetic ring plates 145 inside them attract each other. The magnetic ring plates 145 drive the hollow sleeve rod 141 and the annular plate 142 to perform relative motion. With the cooperation of the gravity of the aluminum foil reel, the contraction action of the expanding member 14 is completed, facilitating the removal of the used aluminum foil reel and preparing for the next feeding at the same time.

[0065] Advantage 3: When cutting aluminum foil coils, in order to ensure the continuity of supply and reduce the replacement frequency, aluminum foil coils with a larger number of layers are used. As the same coil of material is continuously rotated and conveyed, the length of the aluminum foil output by the feeding roller gradually becomes shorter with each rotation, resulting in excessive tension, which may cause the thinner aluminum foil to break. However, the tension adjusting member 16 can change the required tension in real time according to the remaining thickness of the aluminum foil coil. By adjusting the position of the tension wheel 151 up and down, the tension and conveying path of the aluminum foil can reach the optimal state, and the cutting process can proceed more smoothly, reducing the number of cutting interruptions caused by aluminum foil wrinkles, offsets, etc., thereby increasing the output per unit time.

[0066] Advantage 4: Before loading, the positioning wheel 172 is lifted by the tension wheel 151 using the lever principle. When the aluminum foil coil is placed, it presses the positioning wheel 172 to move vertically downward. During this process, the outer circumferential surface of the positioning wheel 172 always fits with the outer circumferential surface of the aluminum foil coil, enabling the position of the tension wheel 151 to be confirmed during loading and adjusting the required tension, eliminating the need for manual adjustment and enabling continuous production and cutting.

[0067] Advantage 5: Both the tensioning member 14 and the tension adjusting member 16 are applicable to cutting aluminum foil coils with different inner diameters and different numbers of layers within a certain range, improving the versatility of the product.

[0068] Advantage 6: Under the action of the gravity of the tension wheel 151, the outer surface of the positioning wheel 172 always fits with the outer surface of the lower side of the aluminum foil coil. As the aluminum foil is continuously released, the diameter of the aluminum foil coil gradually decreases, and the tension and position state of the outermost layer of aluminum foil are also constantly changing. The positioning wheel 172 can adapt to this change by continuously fitting with the outer surface of the aluminum foil coil and continuously applying pressure and friction, always maintaining the restraint on the outermost layer of aluminum foil. Especially when the unwinding speed is relatively fast or the winding of the aluminum foil coil is relatively loose, the positioning wheel 172 can prevent the outermost layer of aluminum foil from slipping due to centrifugal force or uneven internal tension, improving stability and ensuring cutting quality.
