Background technique

Wet wipes are generally moist paper towels used to wipe the skin. At present, wet wipes on the market can be roughly divided into two categories: one is that it has been sterilized itself, but it cannot sterilize other items. It contains skin care ingredients and can only be used for The other is the disinfection wipes that are not only disinfected themselves, but also disinfect other items, which can be used for disinfection or sterilization of skin abrasions and scratches.

The production process of the above two types of wet wipes is roughly the same but there are certain differences, but generally the process includes the process of feeding, adding liquid, folding, palletizing, packaging, and outputting finished products. Among them, the folding process is in the process of wet wipes The production process plays an important role in the rapid prototyping of products.

In the prior art, there are also many wet wipe folding equipment and structures in the production line of wet wipes. However, most of the folding equipment generally adopts a wet wipe disclosed in the patent document with the patent application number: CN202120493828.0. The towel folding device, its main structure includes a frame, the frame is rotatably connected with the lower knife roller, the first folding roller and the second folding roller, and the lower knife roller, the first folding roller and the second folding roller are connected with gears Two sets of the lower knife roller, the first folding roller and the second folding roller are arranged symmetrically, and the two second folding rollers cooperate with each other, the first folding roller cooperates with the second folding roller, and the lower knife roller and the second folding roller cooperate with each other.
