Problems solved by technology

[0005] However, the problem with the manual method is that it is difficult to grasp the force; moreover, the frequency will gradually decrease after a long time of beating, and long-term beating will cause knocking marks on the foil surface being beaten, which has caused many complaints from customers
[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

[0035] 1. Discovery of the problem

[0036] 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.

[0037] 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, 800mm copper foil will wrinkle, while 300mm has a lower probability of wrinkle.

[0038] In other words, the smaller the width of the slit copper foil, the lower the possibility of wrinkling.

[0039] 2. Reason Analysis

[0040] What is the reason for the wrinkling of the above-mentioned copper foil surface:

[0041] 1) For the slitting machine, the copper foil needs to pass through 7-9 shafts from unwinding to winding, that is, the number of passing shafts is relatively large;

[0042] 2) The spacing between the...

Abstract

The invention discloses a guide roller for preventing a wide copper foil from being tightened and an electrolytic copper foil splitting machine, and belongs to the technical field of new energy automobile power battery electrolytic copper foils. According to the technical key points, a first side threaded section and a second side threaded section are arranged on the surface of a guide roller body, and the first side threaded section and the second side threaded section are symmetrically arranged; and the first side threaded section and the second side threaded section are opposite in rotating direction. According to the guide roller for preventing the wide copper foil from being tightened and the electrolytic copper foil splitting machine, the problem that the wide copper foil is wrinkled in a copper foil splitting process can be solved.

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...
