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 caus

Example Embodiment

[0034] Example 1.

[0035] 1. Discovery of the problem

[0036] As described in the background art: when the copper foil is slit, the large width foil will be tightened in the middle, and the copper foil roll will be wrinkled.

[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 is cut into three parts: 300mm+800mm+300mm, 800mm copper foil will be wrinkled in the cut part, while 300mm will have a lower probability of wrinkling.

[0038] That is to say, the smaller the width of the copper foil after slitting, the lower the possibility of wrinkling.

[0039] Second, the reason analysis

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

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

[0042] 2) The distance bet...

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...
