Description

Technical Field

[0001] The present invention relates to the technical field of battery packaging films, and in particular to an aluminum-plastic film rolling and winding device. Background Art

[0002] During the production process of aluminum-plastic film, the aluminum-plastic film is rolled up by a winding device. A roller pressing device is provided above the winding roller. When winding up, the roller pressing device is attached to the winding roller, so that the roller pressing device rolls the aluminum foil on the winding roller. The aluminum foil on the winding roller increases layer by layer, and the roller pressing device is always pressed on the surface of the aluminum foil, so as to obtain an aluminum-plastic film with a smooth surface.

[0003] In the production process of aluminum-plastic film, because the aluminum-plastic film itself has a certain elasticity, the rolling device contacts the aluminum-plastic film unevenly. When the aluminum-plastic film is offset, wrinkles will appear in the winding process of the aluminum-plastic film, which will cause wrinkles or high edges between the films. The wound aluminum-plastic film will produce gas. If the bubbles cannot be discharged or eliminated, the aluminum-plastic film will be deformed, which will easily cause a lot of adverse losses during compounding.

[0004] As disclosed in the comparative document CN202020299869.1, a surface rolling device for aluminum foil of a winding roller comprises a pressure roller and a pressure roller groove symmetrically arranged on the frames at both ends of the winding roller, wherein the pressure roller groove is composed of a vertical groove and a horizontal groove, the long axis of the vertical groove is perpendicular to the horizontal plane and coplanar with the axis of the winding roller, and the horizontal groove is connected with the vertical groove and arranged on one side of the upper part of the vertical groove; the pressure roller is composed of a roller wheel and a mounting shaft at both ends of the roller wheel, the mounting shafts at both ends of the roller wheel are respectively located in the vertical groove and can move up and down along the vertical groove, and the shaft end sleeve of the mounting shaft is provided with a bearing, and the outer diameter of the bearing is matched with the width gap of the vertical groove. This scheme can roll up aluminum foil by matching the winding roller and the pressure roller, but the pressure roller and the winding roller of this scheme are arranged in the pressure roller groove, the pressure roller and the winding roller have the same length, the end of the pressure roller is not in smooth contact with the winding roller, and when the aluminum-plastic film is offset during the winding process, the pressure roller and the winding roller have poor material pressing effects, which makes the aluminum-plastic film prone to high-side winding.

[0027] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0028] like Figures 1 to 3 As shown, an aluminum-plastic film rolling and winding device 10 according to an embodiment of the present disclosure includes a winding roller 100, a winding shaft 200, a support frame 300 and a winding roller assembly 400. The support frame 300 is arranged above the winding roller 100, and the winding roller 100 is rotatably arranged on the winding shaft 200. The winding roller 100 is used to wind up the aluminum-plastic film 500, and the winding roller assembly 400 is used to fit with the aluminum-plastic film 500. When the winding roller 100 rolls up the aluminum-plastic film 500, the winding roller assembly 400 fits and presses the aluminum-plastic film 500, so that the rolled aluminum-plastic film 500 is smoother.

[0029] Furthermore, the roll assembly 400 includes a support shaft 410, a main roller 420 and an extension roller 430. Both ends of the support shaft 410 are respectively connected to the support frame 300. The main roller 420 is provided with a shaft through slot 4201. The extension roller 430 includes an extension roller body 431, an extension intermediate layer 432 and an extension pressure layer 433. The surface Shore hardness of the extension pressure layer 433 is 85-90°, so that the surface hardness of the extension pressure layer 433 is higher and more wear-resistant. The extension pressure layer 433 has a better pressing effect on the aluminum-plastic film 500. The extension intermediate layer 432 connects the extension pressure layer 433 to the aluminum-plastic film 500. On the extension roller body 431, the extension roller body 431 is provided with an extension groove 4301, the extension middle layer 432 is covered on the extension roller body 431, the extension pressure layer 433 is covered on the extension middle layer 432, the extension pressure layer 433, the extension middle layer 432 and the extension roller body 431 are all connected to the main roller 420, the shaft groove 4201 is connected to the extension groove 4301, the support shaft 410 is penetrated by the extension groove 4301 and the shaft groove 4201, and the end cutting edge of the extension pressure layer 433 has a chamfered portion 4331, so that the end of the extension pressure layer 433 is smoother.

Each position of the main roller 420 and the extension pressing layer 433 can press the aluminum-plastic film 500 on the winding roller 100. When the end of the extension pressing layer 433 contacts the aluminum-plastic film 500, the chamfered portion 4331 of the cutting edge of the end of the extension pressing layer 433 contacts the aluminum-plastic film 500.

[0034] like Figure 2 As shown, in one embodiment, the roll assembly 400 further includes a counterweight 440, and a counterweight groove 4302 is provided at one end of the extended intermediate layer 432 away from the main roller 420, the counterweight 440 is installed in the counterweight groove 4302, and one end of the counterweight 440 is connected to the extended roller body 431. In this embodiment, the counterweight 440 can increase the weight, so that the pressing effect of the pressing roller pressing layer 423 on the aluminum-plastic film 500 is better.

[0036] like Figure 2 As shown, in one embodiment, the radius of the counterweight block 440 is greater than the radius of the extension roller body 431. In this embodiment, the counterweight block 440 seals one end of the counterweight groove 4302 to isolate moisture from contacting the extension roller body 431, thereby extending the service life of the extension roller body 431.

[0037] like Figure 2As shown, in one embodiment, the roll assembly 400 further includes a balancing block 450, which is connected to the end of the counterweight block 440 away from the main roll 420. In this embodiment, by adjusting the balancing block 450, the main roll 420 and the extension roll 430 can be dynamically balanced, so that the dynamic balance of the main roll 420 and the extension roll 430 is maintained at 1000 revolutions / min≤10g, so that the main roll 420 and the extension roll 430 can maintain a certain stability during operation, reduce friction and noise, thereby improving production efficiency and product quality.

[0038] like Figure 2 As shown, in one embodiment, there are multiple balancing blocks 450, and the multiple balancing blocks 450 are arranged at intervals at one end of the counterweight block 440 away from the main roller 420. In this embodiment, the multiple balancing blocks 450 can adjust the weights of different positions of the main roller 420 and the extension roller 430 at the same time, so as to facilitate the dynamic balance adjustment of the main roller 420 and the extension roller 430, thereby making the main roller 420 and the extension roller 430 run quickly and stably.

In this embodiment, the winding roller 100 is located below the main roller 420, the aluminum-plastic film 500 on the winding roller 100 is located at the center of the main roller 420, and both sides of the aluminum-plastic film 500 are covered and laminated with the main roller 420 and the extension roller 430, so that the aluminum-plastic film 500 is subjected to more uniform force, thereby achieving a better pressing effect of the aluminum-plastic film 500.

[0040] like Figure 3 As shown, in one embodiment, the thickness of the aluminum-plastic film 500 is 100um-150um. In this embodiment, the main roller 420 and the extension layer 433 roll the aluminum-plastic film 500, and the winding roller 100 rolls the aluminum-plastic film 500, so that the aluminum-plastic film 500 is curled along the winding roller 100 as the center, and the aluminum-plastic film 500 is continuously wound to complete the winding, and the aluminum-plastic film rolling and winding device 10 adjusts the pressure and position to roll and clamp the aluminum-plastic film 500 with a film thickness of 100um-150um, so that the winding effect of the aluminum-plastic film 500 is better, and no wrinkles and high edges appear in the winding process of the aluminum-plastic film 500.
