The production steps of KN95 masks

Towards the end of the year, in order to better control the epidemic in various regions, people need to wear masks when they travel. Whether they are on the way to work or school, timely protection of themselves is the fundamental measure. 

Among them, if you want to wear masks with better protective performance, disposable medical masks and KN95 masks are one of people's choices. However, some friends may not know the composition and production steps. Today, Strong H Machinery Technology  Co., Ltd will talk about it in detail.


 KN95 MASK Machine

1. The composition of medical masks

The medical mask is a combination of meltblown cloth, non-woven fabric, mask belt and nose clip. The outer layer and inner layer are non-woven fabrics, and the middle layer is meltblown cloth. The outermost layer of the mask has an anti-droplet design, the middle layer is the core functional layer, which is mainly used to filter droplets, particles or bacteria, and the inner layer mainly plays a role of moisture absorption.

The main filter material is the melt blown cloth we often say. The melt blown cloth is a kind of ultra-fine electrostatic fiber cloth. It is precisely because of this electrostatic effect that it can capture dust faster and better, and contain all kinds of viruses. After the foam is close to the polypropylene melt blown cloth, it can be adsorbed on the surface of the melt blown cloth. Regarding the selection of meltblown cloth, the higher the weight, the better the protective filtering effect. KN95 uses 40 grams or even higher.

2. Detailed explanation of KN95 mask machinery and equipment

KN95 mask machine is mainly used for the automatic forming of three-dimensional masks. Its working principle is mainly to unwind the whole roll of fabric and then drive it by the roller. The fabric will be unrolled through the whole roll of the nose bridge, and then cut to a fixed length. Imported into the edging fabric for welding, integral forming and welding, driving backwards to continue printing, then welding through ear straps, then folding through the folding mechanism, then ultrasonic tilt sealing, and finally cutting and forming by cutter rollers Falling into the sterile rotating basket, and then being transported to the next disinfection process, this is the operation process of the entire KN95 mask machine.

3. The production capacity of KN95 mask machinery and equipment

Speaking of the production capacity of KN95 mask machinery and equipment is still relatively good, the final product produced is the size of general-purpose masks. Basically one person can complete this work. Of course, the incoming method of this machine requires manual feeding. The blanking method is automatic blanking, which is very convenient, and the production cycle is 35-45 pcs/min.
