Description

Copper foil slitting machine winding pressure roller device

technical field

The utility model relates to the technical field of slitting machines, in particular to a winding pressure roller device of a copper foil slitting machine.

Background technique

Copper foil multi-roll slitting machine generally consists of uncoiling, guide rollers, and then the process of slitting and rewinding to the cutter shaft, and the process of controlling tension and rewinding through precise tension control; during operation, it is set according to different thickness and width of copper foil. Set reasonable tension parameters to achieve winding. As shown in Figure 1, the winding shaft is wound with copper foil by the air-expanding shaft sleeve paper core.

Due to the small roughness on both sides of the ultra-thin copper foil, the ultra-thin copper foil slitting machine has high requirements for winding precision. At the same time, because the copper foil is ultra-thin, the winding shaft is prone to wrinkles, horizontal lines and waves on the surface. Streaks and other phenomena, wrinkling and folding when the tension is increased, and curling when the tension is reduced, resulting in small winding volumes of ultra-thin copper foil slitting machines, such as: the number of meters is short due to the winding of copper foil below 9 microns The phenomenon of rolling and unwinding restricts the development of ultra-thin copper foil; with the market demand for cost reduction, the rewinding weight of ultra-thin copper foil is also increasing, such as: 8 micron thick 600mm wide copper foil, from the original requirement of 20-60 The kilogram per roll is increased to 60-150 kg per roll, which puts higher requirements on the copper foil slitting machine, increases the weight of a single roll, reduces the frequency of changing rolls at different stops during use, reduces the number of times of copper foil splicing, and reduces the number of copper foil rolls In order to achieve the purpose of improving work efficiency and reducing production costs. But this brings difficulty to the production of ultra-thin copper foil. From the slitting machine winding structure and the performance of ultra-thin copper foil itself, increasing the winding length will increase the difficulty. Due to the thin copper foil and the small roughness of the smooth surface, Structural influences such as paper core material limitation, serious horizontal stripes, wavy stripes on the surface and slipping phenomenon will appear when the winding length increases. The production control of each manufacturer should also be adjusted in various aspects accordingly, such as: the improvement of equipment precision, the inner circle of the paper core and Improve the accuracy of the outer circle to solve the problems of horizontal stripes and wavy stripes on the surface, but the effect is not great, and the improvement is not obvious.

Contents of the invention

The purpose of the utility model is to provide a copper foil slitting machine rewinding roller device to solve the problem of large swinging rewinding stripes and slipping that cause wrinkles, horizontal lines, There are bad phenomena such as wavy stripes on the surface.

In order to achieve the above object, the utility model adopts the following technical solutions:

A copper foil slitting machine winding pressure roller device, including a slitter frame, the slitter frame is fixed with a pressure roller guide rail fixing frame, and the pressure roller guide rail fixing frame is fixed with a pressure roller retreat guide rail, Bearings are installed at both ends of the pressure roller, and the pressure roller is installed on the retracting guide rail of the pressure roller through the bearing; During the foiling process, the pressure roller can press the copper foil on the winding shaft tightly, so as to avoid the unfavorable phenomena such as large swinging of the winding stripes, slipping caused by wrinkles, horizontal stripes, and wavy stripes on the surface of the copper foil during the winding process. .

As an improvement of this technical solution, the pressure roller retreat guide rail is provided with an inclined groove, and the bearings at both ends of the pressure roller are installed in the inclined groove, so that the pressure roller can easily move in the groove through the bearing, and It is ensured that the pressure roller will not slip off from the retreat guide rail, which ensures the safety of the operator.

As another improvement of this technical solution, the press roller is a rubber press roller, and the press roller made of rubber material can prevent the copper foil from indentation and other undesirable phenomena while pressing the copper foil, so as to ensure the quality of the copper foil.

As another improvement of the technical solution, the angle between the inclined groove and the horizontal plane is 10-20 degrees, which further ensures that the pressure roller can prevent the copper foil from indentation and other undesirable phenomena while pressing the copper foil.

As a further improvement of this technical solution, the hardness of the rubber is 43-48 degrees, which further ensures that the pressure roller can avoid the indentation of the copper foil while pressing the copper foil.

Compared with the prior art, the utility model has the following technical advantages:

The winding pressure roller device of the copper foil slitter of the utility model is arranged on one side of the winding shaft. By adding a pressure roller on the winding shaft, the pressure roller can put the winding shaft on the winding shaft during the process of winding the copper foil. The copper foil is pressed tightly, so as to avoid the unfavorable phenomena such as large swing of the winding stripes, wrinkles caused by slipping, horizontal stripes, and wavy stripes on the surface of the copper foil during the winding process.
