Problems solved by technology

[0002] Because the thickness of the capacitor film is too thin, the film will shake and flutter during high-speed slitting and winding, and too much air will be involved, which will cause wrinkles during winding

Embodiment 1

[0026] see figure 1 , a slitting double pressure roller, including a base 1, a support 2, a swing arm 3, a clamping arm 4, a rotating arm 5, a first pressure roller 6 and a second pressure roller 7, and the support 2 is fixedly installed on the base 1 Above, one end of the swing arm 3 is hinged on the support 2, the clamping arm 4 is connected with the swing arm 3, the rotating arm 5 is connected with the clamping arm 4, the first pressure roller 6 is rotatably installed on the clamping arm 4, the second Two pressing rollers 7 are rotatably mounted on the rotating arm 5 , and the diameter of the second pressing roller 7 is smaller than that of the first pressing roller 6 .

[0027] It also includes a drive mechanism that drives the swing arm 3 to rotate around the support 2. The drive mechanism is a cylinder 8, the cylinder seat of the cylinder 8 is fixed on the support 2, and the piston rod of the cylinder 8 is hinged to the swing arm 3. The swing arm 3 is driven to swing by...

Embodiment 2

[0032] A kind of winding method of above-mentioned slitting double pressure roller, comprises the steps:

[0033] 1) The film is drawn out from the lower end of the slitting traction roll 13, and wound from the lower end to the bottom of the first pressure roll 6 with a larger diameter;

[0034] 2) The film wound to the bottom of the first press roller 6 is drawn out from the upper end of the first press roller 6, and wound from the upper end to the upper part of the second press roller 7 with a smaller diameter;

[0035] The film wound on the upper part of the second pressing roller 7 is drawn out from the lower end of the second pressing roller 7 and wound onto the finished film roll 14 from the lower end.

[0036] After adopting the above scheme,

[0037] 1. Increase the path between film traction transition and winding, and shorten the gap between rollers;

[0038] 2. In terms of structure, the wrap angle between the film and the transition roller is increased;

[0039]...

Abstract

The invention discloses a slitting dual-pressure roll and a winding method thereof. The slitting dual-pressure roll comprises a base (1), supports (2), swing arms (3), clamping arms (4), rotating arms (5), a first pressure roll body (6) and a second pressure roll body (7). The supports (2) are fixedly installed on the base (1), one ends of the swing arms (3) are hinged to the supports (2), the clamping arms (4) and the swing arms (3) are connected, the rotating arms (5) and the clamping arms (4) are connected, the first pressure roll body (6) is rotationally installed on the clamping arms (4), the second pressure roll body (7) is rotationally installed on the rotating arms (5), and the diameter of the second pressure roll body (7) is smaller than that of the first pressure roll body (6). A thin film is flatly attached to the pressure roll bodies, and it is guaranteed that no excessive air is involved in the rolling process.

Description

technical field [0001] The invention belongs to the technical field of film winding, and in particular relates to a slitting double-pressure roller and a winding method thereof. Background technique [0002] Because the thickness of the capacitor film is too thin, the film will vibrate and flutter during high-speed slitting and winding, and too much air will be involved, which will cause wrinkles during winding. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a slitting double-pressure roller and its winding method which can reduce the generation of film wrinkles and improve the winding effect. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is: a slitting double pressure roller, including a base, a support, a swing arm, a clamping arm, a rotating arm, a first pressure roller and a second pressure roller, the The support is fixedly mounte...
