Background Art

In recent years, with the continuous development of the new energy industry, especially lithium battery separators, it has shown explosive growth. Usually, separators are produced in wide widths and then cut according to the required specifications when used. However, with the continuous development of the separator market, high-efficiency and low-cost production methods have gradually become the mainstream. The width of the separator ranges from 20mm to 3000mm. Existing separator slitting machines usually use two methods of sliding shaft and independent arm for cutting. There are only small-sized products that can be cut. The width is ≥1500mm. The life, accuracy and tension of the sliding shaft or independent arm will be affected, thereby affecting the product quality and unable to achieve wide-span width slitting. Diaphragm manufacturers usually use different slitting machines to cut products of different specifications separately; and purchasing different slitting machines will inevitably incur additional costs. Therefore, a slitting machine that can quickly switch specifications is needed to improve this problem.

The winding mechanism includes a differential shaft winding device 15 and an independent workstation winding device. The side of the side plate 1 surface away from the unwinding roller 14 is provided with a differential shaft winding device 15 through a bearing. The side plate 1 surface is provided with independent workstation winding devices at the upper and lower ends of the differential shaft winding device 15. The independent workstation winding device includes a rotating disk 16, a transmission rod 17, and a motor 18. The side plate 1 surface is provided with a rotating disk 16 at the upper and lower ends of the differential shaft winding device 15. The outer surface of the rotating disk 16 is provided with a transmission rod 17 through a bearing. The motor 18 is fixedly provided on one side of the surface of the rotating disk 16. The output shaft end of the motor 18 is connected to the transmission rod 17 through a coupling. The independent workstation winding device is provided with multiple devices, which are evenly spaced and distributed on one side of the side plate 1. The slit film material can be collected through the winding mechanism. The present winding method provides two winding methods, one is the slip shaft winding device 15 commonly used in the prior art; the other is an independent workstation winding device as an alternative; it has an active motor 18 as a drive; winding rollers of different widths can be installed on its transmission rod 17 as needed; then the motor 18 drives the transmission rod 17 to rotate; thereby driving the winding roller to rotate; thereby winding can be performed;

The slip shaft winding device 15 of the device is a mature existing technology; it has the function of slip ring slipping; when the wound material is too tight, the slip ring will slip with the axis to achieve an ideal tightness, and this tension is related to the size of the internal inflation pressure, and finally it is manifested in the size of the tension;

In addition, the slip shaft can adjust the tension by adjusting the air pressure, so that the entire shaft is at a stable value. Nowadays, slitting machines all have a set of air pressure systems to match the slip shaft winding device 15 for winding work; the air pressure tension will change with the size of the roll diameter, because the larger the roll diameter, the greater the tension required for winding; therefore, this application document will not introduce the specific structure of the slip shaft winding device 15 in detail;

The outer surface of the transmission rod 17 is provided with a spline; the spline can be used to drive and install the winding roller; thereby, the power of the motor 18 can be transmitted to the spline.

Working principle: When using this device, the film material to be cut is released by the unwinding roller 14. At the same time, this device is provided with two unwinding rollers 14, so that after one unwinding roller 14 is used up, it can be quickly switched to realize fast loading and unloading of the film and save time.

Then, the film material on the surface of the unwinding roller 14 is pulled through the guide roller and the cutting knife 8 and is wound around the corresponding slip shaft winding device 15 and the surface of the independent workstation winding device; in this way, the continuous rotation of the slip shaft winding device 15 and the independent workstation winding device can continuously drive the film material to pass through the cutting knife 8, cut the film material into suitable sizes and then distribute and wind it up for storage; and the difference between the slip shaft winding device 15 and the independent workstation winding device at this time is that the slip shaft winding device 15 can automatically slip according to the diameter of the wound film material to change the winding tension; but when the width of the cut film material is greater than or equal to 1500mm; because the film material is wider, the contact position of the winding roller with the slip shaft is wider when it rotates; the control of slippage is relatively poor, and its winding effect is correspondingly reduced;

At this time, an independent workstation winding device can be used to wind up the film material; the advantage of the independent workstation winding device is that it can wind up film materials of various models and widths; but it cannot automatically slip and adjust the tension like the slip shaft winding device 15; but the transmission rod 17 of the independent workstation winding device in the present application document is connected to the motor 18; that is to say, it has an independent drive control; in this way, the tension can also be adjusted according to the different speeds of the motor 18; in this way, the two winding structures of the device can be switched arbitrarily, so that the production of film materials of different specifications can be carried out; in a wider field with a winding width ≥1500mm, the independent workstation winding device can replace the slip shaft winding device 15 for winding work, on the contrary, in a narrower field with a winding width ≤1500mm, the slip shaft winding device 15 will be more convenient when winding;

When the device is used, winding rollers of different specifications can be arranged on the outer side of the transmission rod 17 on the surface of a rotating disk 16, so that it is convenient to switch different winding devices according to the size and width of the specifications.
