Description

Technical Field

[0001] The present invention belongs to the field of wet wipe processing, and specifically relates to a pre-processing device with a pressing function. Background Art

[0002] Wet wipes are moist paper towels used to wipe the skin. Wet wipes on the market can generally be divided into two categories: one type is already disinfected itself but cannot disinfect other items, contains skin care ingredients, and can only be used for skin moistening and maintenance. The other type is disinfected wet wipes that can not only disinfect themselves but also disinfect other items, and can be used for disinfecting or sterilizing skin abrasions, scratches, etc.

[0003] With the progress of society and the improvement of people's living standards, the demand for wet wipes is also increasing continuously. In order to meet people's demand for wet wipes, people have invented some wet wipe processing equipment, among which there is a pre-processing device with a pressing function that rolls and presses non-woven fabrics so that the fiber webs on the non-woven fabrics are evenly distributed;

[0004] However, through research, it is found that the existing pre-processing device with a pressing function has certain drawbacks when in use;

[0005] When the existing pre-processing device with a pressing function is in use, a roll is placed and fed into the rolling device for rolling, and then the rolled non-woven fabric is cut. During this process, the operator needs to repeatedly install and disassemble the unwinding roller. In order to maintain the stability of the unwinding roller, the existing unwinding roller clamp is used for limiting. During the installation and disassembly of the unwinding roller, the bolts need to be repeatedly disassembled and assembled, which is rather troublesome and has low efficiency;

[0006] Secondly, when the existing pre-processing device with a pressing function cuts the rolled non-woven fabric, it usually tightens the non-woven fabric through a tension adjusting device and then uses a cutting device for cutting. However, during the stretching process, some of the fibers on the non-woven fabric will spread, and it is easy to cause uneven quality of the non-woven fabric. Therefore, when the existing tension adjusting device adjusts the tension, with appropriate stretching, since the non-woven fabric has a certain elasticity, the non-woven fabric will shake during cutting, the cutting path will change, and there will be a situation where the local cutting is not standard, which does not meet people's usage requirements. For this reason, we propose a pre-processing device with a pressing function. Summary of the Invention
