Description

Technical Field

[0001] The invention belongs to the technical field of capacitor film production, and in particular relates to an automatic winding device for capacitor film and a winding control method thereof. Background Art

[0002] Metallized film capacitors are capacitors made by winding organic plastic film as dielectric and metallized film as electrode. The films used in metallized film capacitors include polyester, polypropylene, polycarbonate, etc. In addition to the winding type, there are also laminated types. Among them, polyester film dielectric and polypropylene film dielectric are the most widely used. Metallized film capacitors are to evaporate a layer of metal film on the surface of polyester film instead of metal foil as electrode. Because the thickness of the metallized film layer is much smaller than that of the metal foil, the volume after winding is much smaller than that of metal foil capacitors. After the production of metallized film is completed, it needs to be wound with a winding core to facilitate the subsequent transportation, processing, and sales process. However, during the winding process, the metallized film is prone to problems such as winding slack due to the asynchronous speed of winding and feeding, which has a certain impact on the winding work and may cause the wound film to have certain wrinkles and deformations.

[0151] In this embodiment, the outer adjustment cap 23 is threadedly connected to the connecting rod 18, so that the position of the outer adjustment member on the connecting rod 18 can be better adjusted; the position of the outer adjustment cap 23 is adjusted to drive the position of the lower adjustment cap 25 to slide, so as to adjust the position of the outer adjustment member on the connecting rod 18 as a whole, and adjust the tightness of the outer clamping member 21 and the inner clamping member 22 on both sides of the end support plate 19. Since an inner floating member 28 is provided between the lower adjustment cap 25 and the outer adjustment cap 23, the lower adjustment cap 25 can float relative to the outer adjustment cap 23 to a certain extent, and then cooperate with the outer clamping member 21 to better provide good elastic support and limit at the outer end of the end support plate 19, so as to ensure the fit and fit effect between the arc pressure plate 13 and the outer surface of the adjustment roller. Since the lower adjusting cap 25 is pressed against one end of the external clamping member 21, and the deformation cutout 29 is set, when the depth of the cooperation between the lower pressing portion 24 and the clamping groove 26 is deepened, that is, when the end support plate 19 drives the external pressure adjusting member to squeeze the lower adjusting cap 25, the mounting hole is deformed and the internal adjusting block 27 is squeezed to increase the friction force between the internal adjusting block 27 and the connecting rod 18, so that it is more difficult for the lower adjusting cap 25 to float in the direction of the external adjusting cap 23, thereby cooperating with the external clamping member 21 to limit the degree of floating of the arc pressure plate 13 away from the adjusting roller, which can better ensure the effect of the arc pressure plate 13 and the adjusting roller being pressed together.
