Description

Technical Field

[0001] The utility model relates to the technical field of aluminum electrolytic capacitor processing, in particular to an aluminum foil processing device for aluminum electrolytic capacitors. Background Technique

[0002] Aluminum electrolytic capacitors are widely used in power supplies, inverters, switch-mode power supplies, communication equipment, household appliances, automotive electronic equipment, etc. They mainly consist of two metal foils (usually aluminum) and an electrolyte (usually a liquid). One metal foil serves as the negative electrode (usually an aluminum cylinder), and the other metal foil serves as the positive electrode (usually a bent aluminum strip). Among them, the aluminum foil is an important component of the aluminum electrolytic capacitor. During production and processing, it is generally processed by winding and winding it up for subsequent processes such as slitting. As shown in the existing patent technology: After retrieval, the Chinese Patent Network discloses an aluminum foil processing device for aluminum electrolytic capacitors (publication number CN214378061U). When such a device is used, through the setting of a winding support frame, a winding roller, an anti-wrinkle clamping device, and a spacing adjustment device, the processed aluminum foil passes through the anti-wrinkle clamping device and then winds around the winding roller. The anti-wrinkle clamping device clamps the aluminum foil, and at the same time, the spacing adjustment device adjusts the anti-wrinkle clamping device to clamp the spacing of the aluminum foil, improving the winding efficiency and preventing cutting tilt.

[0003] However, for the aluminum foil processing devices for aluminum electrolytic capacitors adopted in the above-mentioned public patents and the existing market, there are still some deficiencies: The existing method of using an anti-wrinkle clamping device to clamp and traction-convey the aluminum foil has a small contact surface for clamping and traction, poor stability for clamping and conveying the aluminum foil, and a single clamping cannot effectively play a gentle anti-wrinkle protection function. Therefore, those skilled in the art have provided an aluminum foil processing device for aluminum electrolytic capacitors to solve the problems raised in the above background technique. Summary of the Utility Model

[0014] Compared with the prior art, the present utility model has the following beneficial effects:

[0015] When the utility model winds and processes aluminum foil, by using the limit combination of the limit ring and the traction roller in the traction assembly, the aluminum foil with different widths can be traction-transported in a roller-feed traction manner. Then, under the elastic combination of the elastic support component and the tensioning roller in the tensioning assembly, the traction-transported aluminum foil is elastically tensioned, so that the aluminum foil can be wound with a proper tension degree. Subsequently, by using the winding function of the reel assembly, the aluminum foil is stably wound. On the one hand, it has a flexible adjustment and use performance, and can adapt to the winding processing of aluminum foils with different widths.

One end of the shaft rod of the calibration lead screw 24 is provided with a calibration handwheel 23. And taking the midline as the boundary, on both sides of the midline of the calibration lead screw 24, positive and reverse threads adapted to the calibration sliding table 25 are symmetrically arranged. On the roller surface of the traction roller 22, track chutes for guiding the calibration sliding table 25 are symmetrically opened. By rotating the calibration handwheel 23, the calibration lead screw 24 is driven to rotate. Using the roller teeth of the positive and reverse threads on the calibration lead screw 24, the two calibration sliding tables 25 are pushed to slide symmetrically along the axis of the traction roller 22, and then the two limiting rings 26 are pushed to slide symmetrically, so as to adjust the distance between the two limiting rings 26 to adapt to the guiding and traction work of aluminum foils of different widths.

[0025] On one side of the bracket supporting the chassis 1, there is a tensioning assembly 3 disposed opposite between two sets of traction assemblies 2. The tensioning assembly 3 includes two sets of top support cylinders 31 that are horizontally opposite. The telescopic end of the top support cylinder 31 is provided with an elastic support member, and the top of the arm rod of the elastic support member is provided with a tensioning frame 36.

On both sides of the body of the top support cylinder 31, there are symmetrically slidably connected lifting guide rods 32 fixedly connected to the telescopic cylinder sleeve 33. By controlling the telescopic end of the top support cylinder 31 to extend, the tensioning roller 37 is pushed to support. Using the elastic combination of the telescopic cylinder sleeve 33 and the force arm pressure rod 35 in the elastic support member, the aluminum foil is elastically supported, and the aluminum foil is elastically tensioned to maintain it at an appropriate tension for traction and conveying, avoiding the occurrence of wrinkles.

[0026] On the other side of the bracket of the support chassis 1, there is a reel assembly 4. The reel assembly 4 includes two sets of reel frames 41 that are horizontally opposite.

[0027] The working principle of the present utility model is as follows: When winding the aluminum foil used for the processing of aluminum electrolytic capacitors, according to the width of the aluminum foil, the alignment handwheel 23 can be rotated in advance to drive the alignment screw rod 24 to rotate. By the driving of the positive and reverse thread teeth on the alignment screw rod 24, two groups of alignment sliding tables 25 are pushed to slide symmetrically along the axis of the traction roller 22, and then two groups of limiting rings 26 are pushed to slide symmetrically to adjust the distance between the two groups of limiting rings 26 to adapt to the guiding and traction work of aluminum foils with different widths. Then, the aluminum foil to be wound and processed is drawn out from the bottom roller surface of the traction roller 22, and the aluminum foil is horizontally guided and oriented by the limiting ring 26 and wound onto the winding shaft 42. Then, the telescopic end of the top support cylinder 31 is controlled to extend to push and support the tensioning roller 37. By the elastic combination of the telescopic cylinder sleeve 33 and the arm pressing rod 35 in the elastic support component, the aluminum foil is elastically supported. By the traction combination of the traction roller 22 and the tensioning roller 37, the aluminum foil is elastically tensioned, guided and tractioned to maintain it at an appropriate tension for traction and transportation to avoid wrinkling. Then, by controlling the operation of the winding motor 44, through the transmission combination of the pulley A 45, the transmission belt 46, and the pulley B 47, the winding shaft 42 is driven to rotate to wind and roll the conveyed aluminum foil. It has a gentle and stable tensioning type traction and winding characteristic, which can improve the winding stability and anti-wrinkle performance of the aluminum foil.
