Description

Technical Field

[0001] The utility model relates to the technical field of aluminum foil winding, and more specifically, it relates to an aluminum foil winding device for capacitor production. Background Art

[0002] During the production of capacitors, a core is wound by a winding machine with a film as a dielectric and an aluminum foil as an electrode. In the prior art, generally, a driving mechanism is used to rotate a winding roller to wind the aluminum foil. However, during the actual winding process, when the aluminum foil is uneven, the aluminum foil is very likely to sway and deviate left and right during the winding process, resulting in poor performance of the capacitors produced subsequently, or even directly causing the capacitors produced to be scrapped, increasing the defective rate of capacitor production, and it is difficult to guarantee the quality of the capacitors.

[0003] In view of the above problems, an aluminum foil winding anti-deviation device disclosed in Chinese Patent No. CN212953337U includes a base and a foil blocking wheel. The base includes a left fixed seat and a right fixed seat, and the foil blocking wheel is fixedly installed between the left fixed seat and the right fixed seat. Blocking blocks protrude from both the left and right ends of the foil blocking wheel.

[0004] In the above solution, the blocking blocks on the aluminum foil wheel block the aluminum foil between the blocking blocks at both ends of the aluminum foil wheel, realizing the positioning of the aluminum foil, preventing the aluminum foil from deviating during the winding process, ensuring the quality of the capacitors produced subsequently, and reducing the defective rate of capacitor production. However, in the above solution, the positions of the two side blocking blocks for deviation correction are fixed and unchanged, resulting in that it can only correct the deviation of aluminum foil with a fixed width, with great limitations.

[0005] Therefore, a solution needs to be proposed to solve this problem. Summary of the Utility Model

[0006] Aiming at the deficiencies of the prior art, the purpose of the present utility model is to provide an aluminum foil winding device for capacitor production. By setting a driving device to drive the two side baffles to move, the distance between the two side baffles can be changed, and deviation correction and limiting can be carried out on aluminum foils with different widths during the winding process.

[0007] The above technical purpose of the present utility model is achieved through the following technical solutions: An aluminum foil winding device for capacitor production includes a base. A winding roller rotatably connected to the base is arranged on the base. A bracket fixedly connected to the base is arranged on one side of the winding roller. Two symmetrically distributed mounting blocks are slidably connected to the bracket. A deviation correction roller is rotatably connected between the two mounting blocks on both sides. A lifting device for driving the two side mounting blocks to move is arranged on the bracket. Two symmetrically distributed baffles are slidably connected to the surface of the deviation correction roller. A cavity is arranged inside the deviation correction roller, and a driving device for driving the two side baffles to move is arranged inside the cavity.

[0008] By adopting the above technical solution, when the aluminum foil is wound by the winding roller, the aluminum foil will first pass between the baffles on both sides of the deviation rectifying roller, and after being limited by the deviation rectifying of the two-sided baffles, it is wound on the winding roller. When operating the winding, the driving device can be used to drive the two-sided baffles to move, so that the distance between the two-sided baffles can be adjusted according to the actual width of the aluminum foil, enabling the baffles to limit and correct the deviation of aluminum foils with different widths, meeting the usage requirements in more situations, with better applicability. At the same time, when different aluminum foils have different tensions, the lifting device can be used to drive the mounting block to lift, so that the mounting block drives the height of the deviation rectifying roller to be adjusted, enabling different aluminum foils to be wound in a tensioned state, improving the winding quality of the aluminum foil.

[0009] The present utility model is further arranged as follows: The driving device includes a gear rotatably connected to the inner wall of the cavity, a driving member for driving the gear to rotate is installed on the inner wall of the cavity, moving rods slidably connected to the inner wall of the cavity are arranged on both the upper and lower sides of the gear, racks meshing with the gear are arranged on the sides of the moving rods close to the gear, link rods are fixedly connected to the other sides of the two moving rods, the link rods are fixedly connected to the baffles at the ends far away from the moving rods, and through grooves for the link rods to extend and move are arranged on the deviation rectifying roller.

[0010] By adopting the above technical solution, when it is necessary to drive the two-sided baffles to move through the driving device, the driving member is used to drive the gear to rotate, and the forward and reverse rotation of the gear can drive the two-sided moving rods to move relatively. When the two-sided moving rods approach each other under the drive of the gear, the two-sided baffles can be driven to approach each other through the link rods, and the distance between the two-sided baffles will be reduced, which is suitable for aluminum foils with smaller widths. When the two-sided moving rods move away from each other under the rotation drive of the gear, the two-sided baffles can be driven to move away from each other through the link rods, and the distance between the two-sided baffles will increase. After adjusting to the appropriate position, the driving member is turned off to stop the gear from rotating. The operation is convenient, and the two-sided baffles can be controlled to move synchronously, enabling the aluminum foil to always be centered and limited for deviation rectification after the baffles are adjusted.

[0011] The present utility model is further arranged as follows: The lifting device includes two accommodating grooves symmetrically arranged on the bracket, lead screws are rotatably connected in the two accommodating grooves on both sides, a driving mechanism for driving the two lead screws on both sides to rotate synchronously is arranged on the bracket, nut seats are sleeved on the two lead screws on both sides, and the two nut seats are respectively fixedly connected to the two mounting blocks.

[0012] By adopting the above technical solution, when it is necessary to lift the mounting blocks on both sides, the driving mechanism drives the lead screws on both sides to rotate synchronously. The lead screws on both sides can drive the nut seats on both sides to move together. The forward and reverse rotation of the lead screws can control the lifting of the nut seats, and the nut seats can drive the mounting blocks and the deviation rectifying rollers to lift, so that the aluminum foil can maintain a good tension during winding.

[0013] The present utility model is further configured as: the driving mechanism includes two fixing frames fixedly connected to the upper end surface of the bracket. Rotating rods with one end rotatably connected thereto are arranged on both fixing frames. The other end of the rotating rod is fixedly connected to the lead screw. A motor for driving the rotation of the rotating rod on one side is installed on one of the fixing frames. Synchronous wheels are sleeved on both rotating rods, and a synchronous belt is sleeved between the two synchronous wheels.

[0014] By adopting the above technical solution, after the motor drives the rotating rod on one side to rotate, the rotating rod on this side can drive the rotating rod on the other side to rotate synchronously through the synchronous wheels and the synchronous belt. The lead screws on both sides can rotate synchronously under the drive of the rotating rods. When the deviation rectifying roller is lifted to an appropriate height, the motor can be turned off, and the operation is convenient.

[0015] The present utility model is further configured as: a limiting rod is fixedly connected to the inner wall of the cavity, and a limiting groove for the limiting rod to pass through is arranged on the moving rod.

[0016] By adopting the above technical solution, during the movement of the moving rod along with the rotation of the gear, the moving rod will move along the limiting rod, making the movement of the moving rod more stable.

[0017] The present utility model is further configured as: a plurality of arrayed universal balls are arranged on the inner wall of the limiting groove, and the universal balls are in contact with the surface of the limiting rod.

[0018] By adopting the above technical solution, during the movement of the moving rod along the limiting rod, the universal balls will roll along the surface of the limiting rod, reducing the friction between the moving rod and the limiting rod and making the movement of the moving rod smoother.

[0019] The present utility model is further configured as: a scale ruler is arranged on the surface of the deviation rectifying roller.

[0020] By adopting the above technical solution, the scale ruler takes the midpoint of the deviation rectifying roller as the 0 scale line and is marked with scales on both sides respectively. In this way, the position and distance of the displacement of the two side baffles can be observed more accurately, making the deviation rectifying and limiting of the aluminum foil more accurate.

[0021] In summary, the present utility model has the following beneficial effects:

[0022] The utility model drives the baffles on both sides to move through a driving device, so that the distance between the two baffles is adjusted according to the actual width of the aluminum foil, enabling the baffles to limit and correct the deviation of aluminum foils with different widths, meeting the usage requirements in more cases and having better applicability. At the same time, when different aluminum foils have different tensions, the lifting device can be used to drive the mounting block to lift, so that the mounting block drives the height of the deviation correction roller to be adjusted, enabling different aluminum foils to be wound in a tensioned state, and improving the winding quality of the aluminum foil.
