The principle of wet wipe equipment

Currently, wet wipes have become an indispensable daily necessity—convenient to carry and readily available whenever you're on the go—making them a must-have item for anyone heading out. After using wet wipes outdoors, people can effectively cleanse and disinfect their skin while gently removing any previous skincare products applied. However, without the protective layer provided by these products, the skin becomes more vulnerable to damage. Wet wipe equipment plays a crucial role in the production process of wet wipes, so let’s dive into how this essential machinery works!

Compared to the aforementioned related technologies, portable wet wipes typically come with an adhesive outer cover for everyday use. However, repeated opening and closing of the cover can weaken its adhesiveness over time, causing the alcohol inside the wipe packaging to easily evaporate. As a result, the lower layers of wipes often become dry by the time they’re ready for use. Key aspects of the wet wipe device technology:

To prevent portable wet wipes from drying out during later use, this application provides manufacturing technology for disinfectant wet wipes.

First, the present application employs the following technical solution in the production technology of disinfectant wipes.

A manufacturing technique for disinfecting wet wipes, comprising the following production steps:

Liquid film hot pressing: Place the liquid film onto the device and apply heat-pressing treatment, causing the liquid film to deform inward toward the conveyor belt side, forming multiple recesses.

Fluid accumulation: Inject disinfectant medium into the concave portion of the fluid-filled membrane.

Outer film lamination of the packaging bag: Spray hot melt adhesive onto the side of the outer film that faces the liquid storage membrane, then bond the lower surface of the liquid storage membrane to the hot melt adhesive-coated side of the outer packaging film.

Laminating the inner film of the packaging bag: Apply hot-melt adhesive to the side of the inner film that faces the fluid-collection membrane. Then, align the side of the fluid-collection membrane featuring the recessed area with the adhesive-coated side of the packaging bag’s inner film, and press them together to close the recess, forming a sealed packaging box.

The wet wipe device arranges the wipe packaging into three layers—starting with the outer film, followed by the liquid-storage film, and finally the inner film. A disinfectant medium is placed inside the recess formed during the heat-pressing process applied to the liquid-storage film, preventing the inner film from leaking the disinfectant into the recess. The inner and outer films are then sealed tightly onto the inner and outer sides of the liquid-storage film, respectively. This ensures that when the user later squeezes the outer wall of the packaging pouch, the inner film compresses the disinfectant medium within the recess, causing the inner film to rupture and release the disinfectant into the pouch, thereby moistening the wipes inside for use as a disinfecting wet towel.

Preferably, the recesses are arranged closely in pairs. By incorporating this structure, the wet wipe device enables the disinfectant medium within the recesses to be compressed against the film inside the packaging pouch: when needed, the outer shell of the pouch is folded inward, causing the concave surfaces of one recess to come into direct contact with those of its adjacent neighbor, thereby mutually pressing the disinfectant medium and ultimately collapsing the film inside the pouch, allowing the disinfectant to flow out. During transportation, however, the adjacent recesses remain separated, preventing them from pressing against each other while simultaneously providing a degree of shock-absorbing protection.

In summary, this application provides at least one beneficial technical effect. When the wipes are used later and the packaging bag contains relatively dry wipes, squeezing the outer wall of the bag forces the disinfectant medium within the concave section of the inner film, causing the inner film to rupture and release the disinfectant into the bag, thereby moistening the wipes. The storage film for the disinfectant wipes is fed from the first upper material rotary table into the heat-pressing device, where it is shaped into a concave form. Next, the disinfectant medium is injected into the concavity via an injection mechanism. Finally, a heat-sealing device is used to bond the outer film, storage film, and inner film of the packaging bag together, forming the final package structure. Meanwhile, the heating platen is activated, and the second drive mechanism lowers and moves the platen downward. Once the mechanism stops, the platen continues its descent until its front edge comes into contact with the liquid-storage film, pressing the film firmly into the groove from the opposite side of the protrusion.
