Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrode foil production, specifically a chemical forming roller for electrode foil production. Background Technology
[0002] Electrode foil is a product obtained by electrochemically or chemically etching high-purity aluminum foil through special processing methods to increase its surface area. Electrode foil is mainly used to manufacture aluminum electrolytic capacitors and is a special material for capacitors. Therefore, the technical performance of electrode foil determines the basic technical indicators of capacitors.
[0003] In existing technologies, patterns are typically set on the outer surface of the forming roller to prevent the electrode foil from shifting. However, if the electrode foil is thin, the patterns added to the outer surface of the forming roller can cause the electrode foil to deform, thus affecting its subsequent use.
[0004] For example, patent CN209607600U discloses a chemical forming roller for the production of chemical forming foil, which has a pattern on the surface of the roller body, the pattern being a thread pattern or an annular pattern, and the two ends of the roller body surface are provided with slopes of 3 to 15 degrees. However, for thinner electrode foils, this device has problems such as easily causing deformation of the electrode foil.
[0005] For example, CN205900338U patent also discloses a chemical forming roller for the production of chemically formed foil. However, the device uses several stainless steel tubes to form the roller body. The surface of the stainless steel tubes is coated with a polytetrafluoroethylene layer. The purpose of this device is to improve the wear resistance of the roller and delay the time for crystallization to form on the roller surface.
[0006] The patent CN222213963U discloses another type of forming roller for capacitor forming foil production, which includes a motor, a rotating sleeve, a moving gear, a fixed gear ring, a rotating roller, a rotating sleeve, a limiting rod, a moving frame, a reciprocating screw, and other structures. However, the purpose of this device is to use the moving frame to clean the surface of the rotating roller and push the impurities that fall into the rotating sleeve to one side, so that the cleaned impurities fall onto the worktable for easy subsequent cleaning. In addition, the structure of this device is relatively complex. Utility Model Content
[0007] The purpose of this utility model is to provide a forming roller for electrode foil production, which uses movable limiting sleeves on both sides to replace the roller surface pattern in the prior art to prevent electrode foil from shifting. This not only avoids the problem of electrode foil deformation, but also can be applied to electrode foils of different widths. Furthermore, the anti-shift positioning control is accurate and the use is flexible.
[0008] The objective of this utility model is achieved through the following technical solution:
[0009] A forming roller for electrode foil production includes a roller body, limiting sleeves, a fixing component, and an adjusting component. The roller body is provided with a fixing mounting groove and an adjusting mounting groove. The fixing component is disposed in the fixing mounting groove, and the adjusting component is disposed in the adjusting mounting groove.

Movable limiting sleeves are fitted at both ends of the roller body. A nut block is provided inside the limiting sleeve, which is embedded in the adjusting mounting groove and fitted onto the adjusting screw.
[0010] The roller body is mounted on the mounting plates on the corresponding sides at both ends. The mounting plates are provided with annular mounting grooves and ball bearings are evenly distributed in the mounting grooves. The roller edges at both ends of the roller body are respectively embedded in the mounting grooves on the corresponding side mounting plates and make contact with the ball bearings. A limiting protrusion is provided on the inner side of the mounting groove to limit the position of the roller edge.
[0011] A roller motor is provided on the mounting plate on one side. The mounting plate has a through hole in the middle and the output shaft of the roller motor passes through the through hole and is connected to the corresponding end of the roller body.
[0012] Both ends of the roller body are provided with guide grooves, and the inner side of the limiting sleeve is provided with guide blocks that slide into the corresponding guide grooves.
[0013] The adjusting device is a dual-output shaft motor, and the two shaft ends of the adjusting device are respectively connected to the adjusting screws on the corresponding sides. The screw nut block inside the limiting sleeve is fitted onto the adjusting screw on the corresponding side.
[0014] The limiting sleeve is a conical sleeve with a narrow inner end and an flared outer end, and the narrow inner end of the limiting sleeve is fitted onto the roller body and is provided with a nut block and a guide block.
[0015] The fixing assembly includes springs and clamps, wherein the two clamps are respectively connected to the corresponding side wall of the fixing mounting groove through a set of springs on the corresponding side, and the end of the electrode foil is clamped and fixed by the two clamps.
[0016] The advantages and positive effects of this utility model are as follows:
[0017] 1. This utility model uses movable limiting sleeves on both sides to replace the roller surface pattern in the prior art to prevent electrode foil from shifting. In this way, the electrode foil can be directly wound onto the roller body, and the number of slots on the roller body is very small, so the deformation problem of the electrode foil can be avoided.
[0018] 2. This utility model utilizes an adjustment component to drive the opening and closing movement of the limiting sleeves on both sides, which can be applied to electrode foils of different widths. Furthermore, the adjustment component is driven by an adjustment screw, which can precisely control the movement distance of the limiting sleeves, ensuring accurate anti-deviation positioning control and flexible use.
[0019] 3. The present invention has a guide groove on one side of the roller body, and the guide block inside the limiting sleeve is slidably embedded in the corresponding guide groove. This not only ensures the linear movement of the limiting sleeve, but also does not increase the number of slots on the roller body too much, thereby avoiding the problem of electrode foil deformation.
[0020] 4. This utility model has mounting grooves with evenly distributed balls inside the mounting plate, and the roller edges at both ends of the roller body are respectively embedded in the mounting grooves on the corresponding side mounting plates and make contact with the balls in the grooves, so as to ensure smooth rotation of the roller body and not affect the opening and closing movement of the limit sleeves on both sides.

Detailed Implementation
[0026] The present invention will now be described in further detail with reference to the accompanying drawings.
[0027] like Figures 1-4As shown, this utility model includes a roller body 3, limiting sleeves 4, a fixing component 6, and an adjusting component 5. The roller body 3 has a fixing mounting groove 303 and an adjusting mounting groove 301 along its axial direction. The fixing component 6 is disposed in the fixing mounting groove 303, and the adjusting component 5 is disposed in the adjusting mounting groove 301. The adjusting component 5 includes an adjusting device 501 and an adjusting screw 502, with the adjusting screw 502 driven to rotate by the adjusting device 501. Movable limiting sleeves 4 are fitted at both ends of the roller body 3, and a screw thread block 401 is provided inside the limiting sleeve 4, embedded in the adjusting mounting groove 301 and fitted onto the adjusting screw 502. During operation, the electrode foil's displacement is limited by the limiting sleeves 4 on both sides to prevent offset. Simultaneously, the spacing of the limiting sleeves 4 on both sides can be adjusted according to actual needs by the adjusting screw 502. This ensures that the electrode foil is prevented from offset while also being applicable to electrode foils of different widths, making it more flexible in use.
[0028] like Figures 1-4 As shown, in this embodiment, the two ends of the roller body 3 are respectively mounted on the mounting plates 2 on the corresponding sides, and the mounting plates 2 are disposed on the corresponding equipment frame, wherein... Figure 2 As shown, the mounting plate 2 has an annular mounting groove 202, and the mounting groove 202 is evenly distributed with ball bearings 204, such as... Figure 3 As shown, the roller edges 304 at both ends of the roller body 3 are respectively embedded in the mounting grooves 202 on the corresponding side mounting plates 2 and make contact with the ball bearings 204, thereby realizing the rotation of the roller body 3. A limiting protrusion 203 is provided on the inner side of the mounting groove 202 to limit the position of the roller edge 304.
[0029] like Figure 1 As shown, in this embodiment, a roller motor 1 is provided on the mounting plate 2 on either side to drive the roller body 3 to rotate, such as... Figure 2 As shown, the mounting plate 2 has a mounting plate through hole 201 in the middle, and the output shaft of the roller motor 1 passes through the mounting plate through hole 201 and is connected to the corresponding end of the roller body 3.
[0030] like Figure 1 and Figure 3 As shown, in this embodiment, guide grooves 302 are provided at both ends of the roller body 3, and guide blocks 402 are provided on the inner side of the limiting sleeve 4 and are slidably embedded in the corresponding guide grooves 302. The movement of the guide blocks 402 along the guide grooves 302 can ensure that the limiting sleeve 4 moves linearly along the axial direction of the roller body 3. In addition, the guide grooves 302 at both ends of the roller body 3 can also limit the inward displacement of the limiting sleeve 4. At the same time, in this embodiment, guide grooves 302 are only provided on one side of the roller body 3, so as not to increase the number of slots on the roller body 3 too much, thereby avoiding the problem of electrode foil deformation.
[0031] like Figure 1 and Figure 3 As shown, in this embodiment, the adjusting device 501 is a dual-shaft motor, and the two shaft ends of the adjusting device 501 are respectively connected to the adjusting screws 502 on the corresponding sides to drive the limiting sleeves 4 on both sides to open and close synchronously. The adjusting screws 502 on both sides of the adjusting device 501 rotate in opposite directions, and the screw nut block 401 inside the limiting sleeve 4 is fitted onto the adjusting screw 502 on the corresponding side. In addition, in this embodiment, the bottom of the adjusting mounting groove 301 is provided with a wire passage hole that communicates with the outside of the roller body 3. The cable connected to the adjusting device 501 passes through the wire passage hole and the mounting plate through hole 201 on the mounting plate 2 away from the roller motor 1 and then connects to the external control system.
[0032] like Figure 1 and Figure 3 As shown, in this embodiment, the limiting sleeve 4 is a conical sleeve with a narrow inner end and an flared outer end. The narrow inner end of the limiting sleeve 4 is fitted onto the roller body 3 and is provided with a nut block 401 and a guide block 402. The flared outer end of the limiting sleeve 4 abuts against the mounting plate 2, which can limit the outward movement of the limiting sleeve 4.
[0033] like Figure 1 and Figures 3-4 As shown, in this embodiment, the fixing component 6 includes a spring 601 and a clamping plate 602. The two clamping plates 602 are respectively connected to the corresponding side wall of the fixing mounting groove 303 through a set of springs 601 on the corresponding side. The end of the electrode foil is clamped and fixed by the two clamping plates 602, and the two clamping plates 602 provide sufficient clamping force through the springs 601 on both sides.
[0034] The working principle of this utility model is as follows:
[0035] In operation, the electrode foil ends are clamped and fixed by two clamping plates 602 in the fixing assembly 6. Then, the spacing of the limiting sleeves 4 on both sides of the roller body 3 is adjusted by the adjusting assembly 5 according to the electrode foil width specifications. The adjusting device 501 in the adjusting assembly 5 drives the adjusting screws 502 on both sides to rotate, which in turn drives the limiting sleeves 4 on both sides to open and close through the screw block 401 inside the limiting sleeve 4. At the same time, the guide block 402 inside the limiting sleeve 4 moves along the corresponding guide groove 302 on the roller body 3 to ensure that the limiting sleeve 4 moves in a straight line. With the above structure, this invention can prevent the electrode foil from shifting and can also be applied to electrode foils of different width specifications. After the position of the limiting sleeve 4 is determined, the roller motor 1 starts to drive the roller body 3 to rotate and start winding. The roller edges 304 on both sides of the roller body 3 respectively cooperate with the ball bearings 204 in the mounting grooves 202 on the corresponding mounting plates 2 to ensure smooth rotation and not affect the movement of the limiting sleeves 4.
