Problems solved by technology

[0005] However, the problem with the artificial method is that it is difficult to grasp the strength; moreover, the frequency will gradually decrease after a long time of beating
[0009] That is to say, there is no report on the wrinkling of large and wide foils during the copper foil slitting process in the existing literature
And how to deal with the above problems, no relevant enterprises have conducted research

Embodiment 1

[0034] 1. Discovery of the problem

[0035] As mentioned in the background technology: when the copper foil is slitting, the copper foil will be tightened towards the middle for a large width of the foil during slitting, and the copper foil roll will wrinkle.

[0036] After a lot of data analysis: when the copper foil obtained by slitting is more than 800mm, it is very easy to wrinkle. For example: 1400mm original foil, cut into three parts: 300mm+800mm+300mm, the 800mm copper foil cut part will appear wrinkle, while the 300mm copper foil has a lower probability of wrinkle.

[0037] In other words, the smaller the width of the slit copper foil, the lower the possibility of wrinkling.

[0038] 2. Reason analysis

[0039] What is the reason for the wrinkling of the above-mentioned copper foil surface:

[0040] 1) For the slitting machine, the copper foil needs to pass through 7-9 axes from unwinding to winding, that is, the number of passing axes is relatively large;

Abstract

The invention discloses a guide roller for anti-tightening of wide copper foil and an electrolytic copper foil slitting machine; it belongs to the technical field of electrolytic copper foil for power batteries of new energy vehicles; its technical points include: a first A side thread segment and a second side thread segment, the first side thread segment and the second side thread segment are arranged symmetrically; the first side thread segment and the second side thread segment have opposite directions of rotation. The wide-width copper foil anti-tightening guide roller and the electrolytic copper foil slitting machine of the present application can solve the problem of wrinkling of the large-width copper foil during the copper foil slitting process.

Description

technical field [0001] The present invention relates to the field of electrolytic copper foil for power batteries of new energy vehicles, and more specifically relates to a guide roller for anti-tightening of wide-width copper foil and an electrolytic copper foil slitting machine. Background technique [0002] The slitting process is a necessary process for electrolytic copper foil. [0003] The applicant was conducting electrolytic copper foil and found the following problems: [0004] As attached to the manual Figure 1-2 As shown, when the copper foil is slit, the copper foil will be tightened towards the middle for a large width of the foil during slitting, and the copper foil roll will wrinkle; to solve this problem, the applicant adopts a manual method: start the slitting During the machine, it is necessary to manually tap the middle part of the copper foil with a light pearl cotton stick with appropriate force and a reasonable frequency to disperse the tightened stri...
