In practical applications, the intermittent transmission method not only leads to low efficiency, but also inevitably causes wrinkles in the film due to temperature differences, affecting subsequent use.

[0009] The flattening mechanism includes two flattening plates, which are arranged vertically at intervals and located between the cooling component and the winding disc. The two flattening plates form a flattening gap, through which the capacitor film passes and is wound onto the winding disc.

[0010] In an optional embodiment, the flattening plate includes a flattening section and guide sections disposed on opposite sides of the flattening section.

In this application, the capacitor film passes sequentially through the heating component, the cooling component, and the flattening gap formed by the two flattening plates, finally winding onto the winding disc. By using two flattening plates, the cooled capacitor film can be flattened, largely avoiding wrinkles. Furthermore, because this application adds a flattening mechanism, the stroke of the capacitor film winding onto the winding disc is increased, and the flattening plates can also conduct some heat.

[0032] Reference Figures 1 to 5 This utility model proposes a capacitor film winding device 1.

[0033] In this embodiment of the present invention, the capacitor film winding device 1 includes a frame 100; a winding mechanism 200 including a winding drive motor 210 and a winding disk 220, wherein the winding drive motor 210 is mounted on the frame 100 and the winding disk 220 is tractively connected to the output shaft of the winding drive motor 210; a heating component 300 and a cooling component 400 are spaced apart on the frame 100; and a flattening mechanism (not shown) including two flattening pressure plates 510, which are spaced vertically apart and located between the cooling component 400 and the winding disk 220. The two flattening pressure plates 510 form a flattening gap 510a, through which the capacitor film 2 passes and is wound on the winding disk 220.

[0034] Specifically, in this application, the frame 100 is formed by splicing metal profiles and sheet metal. The winding drive motor 210 of the winding mechanism 200 is fixed to the frame 100 by screws or the like. The winding disc 220 is sleeved on the output shaft of the winding drive motor 210. Driven by the motor, the winding disc 220 rotates relative to the frame 100 to wind up the capacitor film 2.

[0035] The cooling assembly 400 includes a cooling box 410 and two cooling rollers 420. The cooling box 410 is mounted on the frame 100 and has a rectangular shell cavity structure, forming a cooling cavity 410a and an air inlet 410b and an air outlet 410c that connect to the cooling cavity 410a. The air inlet 410b is located at the top of the cooling box 410, and the air outlet 410c is formed by a combination of multiple air outlet holes. The air inlet 410b can be connected to external refrigeration equipment through a pipe, that is, cold air enters the cooling cavity 410a through the air inlet 410b and cools the capacitor film 2 inside the cooling cavity 410a. The two cooling rollers 420 are spaced apart in the cooling cavity 410a. The two cooling rollers 420 can be made of metal and are rotatably connected to the frame 100. The upper and lower surfaces of the capacitor film 2 are respectively attached to the two cooling rollers 420. In this application, the capacitor film 2 is cooled by cold air in the cooling chamber 410a, which makes the cooling more uniform and the effect better. At the same time, the two metal cooling rollers 420 can conduct heat from the upper and lower surfaces of the capacitor film 2, thus making the cooling effect even better.

[0036] The heating assembly 300 includes a heating box 310 and a heating plate 320. The heating box 310 is installed upstream of the cooling box 410. That is, the heating assembly 300 and the cooling assembly 400 are arranged sequentially along the winding direction of the capacitor film 2. The heating box 310 forms a heating cavity 310a, and the heating plate 320 is disposed in the heating cavity 310a and fixedly connected to the frame 100. After the capacitor film 2 enters the heating box 310, its lower surface is located above the heating plate 320. Two heating support rollers 330 are also provided opposite to the heating plate 320 to support the capacitor film 2 and prevent it from directly adhering to the heating plate 320. In this application, the heating plate 320 is made of a thermally conductive metal, such as steel or iron, and a metal heating tube is disposed below it. The metal heating tube can heat the heating plate 320 so that it can uniformly heat the capacitor film 2.

[0037] The two flattening plates 510 of the flattening mechanism are arranged vertically at an interval and are located between the cooling component 400 and the winding disc 220, forming a flattening gap 510a. In this application, the capacitor film 2 passes sequentially through the heating component 300, the cooling component 400, and the flattening gap 510a formed by the two flattening plates 510, and is finally wound onto the winding disc 220. That is, by setting two flattening plates 510, the cooled capacitor film 2 can be flattened, which largely avoids wrinkles in the film. At the same time, since the flattening mechanism is added in this application, the stroke of the capacitor film 2 winding on the winding disc 220 is increased, and the flattening plates 510 can also conduct some heat. Therefore, the capacitor film 2 can be fully cooled within a limited stroke without the need for intermittent transmission, thus the winding efficiency of the capacitor film winding device 1 is higher.

[0038] Please see again Figure 5 The flattening plate 510 includes a flattening section 511 and guide sections 512 disposed on opposite sides of the flattening section 511. The guide sections 512 and the flattening section 511 are set at an obtuse angle. In this application, the flattening section 511 and the two guide sections 512 are integrally formed of metal, with an arc-shaped transition between the flattening section 511 and the guide sections 512. The two vertically spaced flattening sections 511 form a flattening gap 510a, and the two vertically opposite guide sections 512 are flared. It can be understood that the "flattening gap 510a" is the distance between the two parallel flattening sections 511. The width of the flattening gap 510a can be slightly larger than the thickness of the electro-optical film, so that the two flattening sections 511 can flatten the wrinkles of the capacitor film 2. The flared guide sections 512 can allow the capacitor film 2 to flow into and out of the flattening gap 510a in a better manner. In this application, the flattening plate 510 has a simple structure and a good flattening effect.

[0039] Furthermore, the flattening mechanism also includes a fixed edge-pressing limit block 520 and a movable edge-pressing limit block 530. Specifically, the fixed edge-pressing limit block 520 and the movable edge-pressing limit block 530 are located downstream of the two flattening pressure plates 510, that is, in the next section along the winding direction, the fixed edge-pressing limit block 520 and the movable edge-pressing limit block 530 are arranged opposite to each other, and the fixed edge-pressing limit block 520 and the movable edge-pressing limit block 530 can respectively adhere to the upper surface of the two side edges of the capacitor film 2. This not only further flattens the edges of the capacitor film 2, but also guides the capacitor film 2 to be straight, preventing it from deviating during the winding process.

[0040] Furthermore, in this embodiment, the movable edge-pressing limiting block 530 can move toward or away from the fixed edge-pressing limiting block 520. Specifically, the movable edge-pressing limiting block 530 is provided with two connecting rods 531, and the frame 100 has two connecting holes. One connecting rod 531 can be slidably inserted into one connecting hole. That is, by adjusting the depth of the connecting rod 531 inserted into the connecting hole, the distance between the movable edge-pressing limiting block 530 and the fixed edge-pressing limiting block 520 can be set so that the two can limit the capacitor films 2 of different widths.

[0041] In this embodiment, the flattening mechanism further includes two flattening rollers 540. The two flattening rollers 540 are disposed downstream of the fixed edge-pressing limit block 520 and the movable edge-pressing limit block 530, and are spaced vertically apart. The two flattening rollers 540 are rotatably connected to the frame 100. The capacitor film 2 passes through the gap between the two flattening rollers 540, and its two opposing surfaces are respectively attached to the two flattening rollers 540. By providing two flattening rollers 540, the capacitor film 2 can be further flattened, thus reducing wrinkles in the capacitor film 2.

[0042] Furthermore, the flattening mechanism also includes a flattening drive motor (not shown), which is mounted on the frame 100 and connected to one of the flattening rollers 540. Thus, the flattening drive motor can make the transfer of the capacitor film 2 smoother and the surface flatter.

[0043] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
