Description

Technical Field

[0001] The utility model belongs to the technical field of capacitor manufacturing, and in particular relates to a paper path structure of a winding machine. Background Art

[0002] The winder is a fully automatic stitching and winding machine for producing lead-type aluminum electrolytic capacitors. It has the function of fully automatic stitching and winding of aluminum foil, electrolytic paper, guide needles, tape and other materials according to the determined product and process requirements. The winder equipment is designed as a paperless structure. Electrolytic paper products with a width of 12 mm to 36 mm can be produced on the same equipment without replacing any parts, and it is easy to operate. However, when the equipment winds solid aluminum-plastic electrolytic paper, paper slips easily, resulting in poor overlap between positive and negative aluminum foils, and the products produced cannot meet the process requirements. Since the electrolytic paper aisle is designed as a roller structure, the friction between the electrolytic paper and the roller is very small during winding. In particular, the plastic electrolytic paper used in the production of solid aluminum capacitors is smoother than ordinary electrolytic paper and has less friction with the roller. When the winding needle is wound to the guide pin riveting position, the force on the winding needle changes, causing the product to run away from the paper and foil, resulting in the overlap of the positive and negative foils failing to meet the process requirements, among which the technical process requires to be less than 0.35um. In particular, the solid aluminum electrolytic paper is relatively smooth, which has a greater impact during winding. Utility Model Content

Two rollers A5 are arranged here, which is channel B, used for rolling out the negative aluminum foil 12, wherein the negative aluminum foil 12 is placed on the roller A5 on the right side.

[0023] The paper path A1, paper path B2 and paper path C3 all include a pressing plate 7, a roller A5 and a roller B6. The pressing plate 7 can press the electrolytic paper 10 to increase the friction of the electrolytic paper 10 when winding; the roller A5 and the roller B6 are used to control the winding and movement direction of the electrolytic paper 10. In the paper path A1 and the paper path B2, one pressing plate 7 is provided, three rollers A5 are provided, and one roller B6 is provided.
