[0002] In order to prevent the metallized film from being stacked together during unwinding and rewinding, resulting in short circuits, it is necessary to clean the metal layer on the film surface. The principle of cleaning is to use two energized aluminum foils to generate an electric arc to clean the surface of the metal layer.

[0003] In the requirement of cleaning the double-sided metal layer of the metallized film with aluminum foil, a mechanism for cleaning the double-sided aluminum foil by a winding machine is needed. In the prior art, during the long-term cleaning process of the metallized film with the negative metal rod, the surface of the negative metal rod is prone to overheating problems. Therefore, it is necessary to solve the problem of overheating of the negative metal rod. This problem will cause the film to shrink when it contacts the metal film, thereby affecting the quality of the film capacitor. In view of the deficiencies of the prior art, we propose an aluminum foil cleaning structure of a film capacitor winding machine to solve the above problems. Content of the Utility Model

[0005] A cylinder body is fixedly connected to the outer wall of the substrate. A connection component is arranged at one end of the cleaning swing arm. The connection component is connected to the swing block. When the cylinder body works, the connection component drives the cleaning swing arm to press down, so that the positive aluminum foil and the negative aluminum foil squeeze the metallized film.

[0006] Preferably, the rotary sleeve and the rotary air joint are respectively fixedly installed on the outer walls of the upper cover and the lower cover.

On this basis, an air flow passage is added at the position of the heated negative metal rod to reduce the surface heat of the metal rod, thereby improving the production quality of the metallized film. Through structural design and improvement, with the smallest occupied space, the design purpose is achieved and the production requirements are met. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] To make the objectives, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model are described clearly and completely. Apparently, the described embodiments are some but not all of the embodiments of the utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the utility model without creative efforts shall fall within the protection scope of the utility model.

[0024] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0025] The embodiments of the utility model disclose an aluminum foil cleaning structure of a thin film capacitor winding machine.

[0026] According to the appendix Figures 1-6As shown in the figure, it includes a swing block 1 rotatably connected to the outer wall of the substrate. A cleaning swing arm 5 and a cleaning seat 8 are arranged on the inner wall of the substrate. The cleaning swing arm 5 and the cleaning seat 8 are respectively the fixed side and the swing side. Both the cleaning swing arm 5 and the cleaning seat 8 are cleaning mechanisms. A metallized film 17 is arranged between the cleaning swing arm 5 and the cleaning seat 8. Roller 9, negative cleaning rod 7, and positive cleaning rod 10 are arranged at both the cleaning swing arm 5 and the cleaning seat 8. Positive aluminum foil 15 and negative aluminum foil 16 are respectively wound around the roller 9, negative cleaning rod 7, and positive cleaning rod 10. Upper cover plates 18 are fixedly connected to the outsides of the roller 9, negative cleaning rod 7, and positive cleaning rod 10 at the cleaning swing arm 5. Lower cover plates 27 are fixedly connected to the outsides of the roller 9, negative cleaning rod 7, and positive cleaning rod 10 at the cleaning seat 8. A temperature reduction component is arranged at the negative cleaning rod 7. The temperature reduction component includes a rotary air joint 6, a rotary sleeve 14, and an air pipe 11. The rotary sleeve 14 is installed at both ends of the negative cleaning rod 7. The rotary air joint 6 is installed on the rotary sleeve 14. One end of the rotary air joint 6 is connected to the inside of the negative cleaning rod 7, and the other end of the rotary air joint 6 is connected to the air pipe 11. One end of the air pipe 11 is connected to an air pump on the outer wall of the substrate. By operating the air pump, air flow is filled into the inside of the negative cleaning rod 7 through the air pipe 11 and the rotary air joint 6, which can make the air flow act on the inside of the negative cleaning rod 7, and thus can reduce the temperature on the surface of the negative cleaning rod 7, avoiding the situation that the negative cleaning rod 7 has too high a temperature and damaging the metallized film 17.

[0027] A cylinder main body 3 is fixedly connected to the outer wall of the substrate. A connecting component is arranged at one end of the cleaning swing arm 5. The connecting component is connected to the swing block 1. When the cylinder main body 3 works, the connecting component drives the cleaning swing arm 5 to press down, so that the positive aluminum foil 15 and the negative aluminum foil 16 extrude the metallized film 17. The positive aluminum foil 15 and the negative aluminum foil 16 are led out from the aluminum foil hanging shaft of the winding machine, respectively wound around the roller 9, positive cleaning rod 10, and negative cleaning rod 7 of the cleaning swing arm 5 and the cleaning seat 8 of the aluminum foil cleaning mechanism, and the ends are wound around the aluminum foil winding hanging shaft. The metallized film 17 is led out from the material hanging shaft, passes through the path roller 9 of the winding machine, passes between the cleaning swing arm 5 and the cleaning seat 8, and the end is wound around the winding needle of the main winding mechanism of the winding machine. By starting the winding machine, the production preparation work is completed. The effects produced by the above structure are the prior art.

[0028] The rotary sleeve 14 and the rotary air joint 6 are respectively fixedly installed on the outer walls of the upper cover plate 18 and the lower cover plate 27. An insulating sleeve 13 is arranged at the rotary sleeve 14. One end of the negative cleaning rod 7 is respectively connected to the upper cover plate 18 and the lower cover plate 27 through a bearing main body 12. By arranging the upper cover plate 18 and the lower cover plate 27, the cleaning rod and the roller 9 mandrel can be connected together, increasing the strength of the structure.

[0029] The connecting component includes a bearing seat 4 and a rotating shaft 25. The bearing seat 4 is fixedly installed on the inner wall of the substrate. One end of the rotating shaft 25 is fixedly connected to the cleaning swing arm 5, and the other end passes through the bearing seat 4 and is fixedly connected to the swing block 1. On the metallized film 17 capacitor winding machine, during the cleaning process of the metallized film 17, a mechanism that can place aluminum foils on both the front and back sides of the metallized film 17 is newly added, meeting the production requirements of the metallized film 17 with double-sided metal layers.

[0030] On both sides of the swing block 1, a limit seat 2 and a cylinder seat 26 are respectively arranged. The limit seat 2 and the cylinder seat 26 are both fixedly installed on the outer wall of the substrate. A limit screw 22 is threadedly connected inside the limit seat 2. One end of the limit screw 22 is fixedly connected to a limit block 24. When the cleaning mechanism starts to work, the cylinder body 3 on the back side of the swing acts. With the cooperation of the top block 23, the swing block 1, and the limit block 24, the connecting component can drive the cleaning swing arm 5 to press down towards the position where the fixed side is located. At this time, the metallized film 17 therebetween is extruded by the aluminum foil. Due to the continuous winding action, it still moves towards the winding mechanism. At the same time, the positive and negative electrodes of the aluminum foil cleaning are in contact, and the current is conducted. The aluminum foil take-up reel takes back the aluminum foil. The rollers 9 and the positive cleaning rod 10 and the negative cleaning rod 7 on the cleaning mechanism also rotate under the influence of the friction force of the aluminum foil, thereby transferring the metal dust to the entire roll of aluminum foil. Moreover, the heat generated on the negative cleaning rod 7 during long-term operation is also reduced under the influence of the air flow passage on its inner wall.

[0031] A cylinder body 3 is arranged at the cylinder seat 26. The front end of the cylinder body 3 is fixedly connected to a top block 23. A spring screw 20 is arranged in the top hole of the swing block 1. A fixing screw 21 is fixedly connected to the outer wall of the substrate. A return spring 19 is fixedly connected between the spring screw 20 and the fixing screw 21.

[0032] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and all these changes and improvements fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
