Experts on the function of the mask certification

A range of new research on face coverings shows that the risk of infection to the wearer decreases by 65%, says Dean Blumberg, chief of pediatric infectious diseases at the University of California, Davis Children’s Hospital.

Blumberg and Ristenpart repeatedly made the point that research continues to support the fundamental methods to prevent spreading COVID-19: Wear masks, maintain social distance, and keep social interactions outdoors whenever possible.

The product configuration of mask binding machine

Product Brief

A body machine. After the mask body is output by the body machine, the mask semi-finished products can be processed into finished products by spot welding machine. This machine adopts PLC, touch screen control, single-phase motor for main conveyor belt, stepping motor for turning, accurate transmission, stable control and adjustable speed. Aluminum alloy frame, lighter and stronger. High stability. Fully automatic. Once the non-woven material in the unwinding part is exhausted, the machine will stop automatically.

Working principle

This machine creatively combines the cup mask edge melting and punching cutting two independent processes, multi station turntable, welding with cutting device, welding and cutting at the same time, using PLC control system, touch screen settings, simple and convenient operation, can be used by a single person, only need workers to release and take materials, which can greatly save labor Automatic production, can use 1 ~ 4 layers of PP spunbonded non-woven fabric activated carbon and filter materials, the whole machine from raw material feeding to nose line insertion, edge sealing, cutting finished products are all one line automatic operation, according to the different raw materials used, it can reach different standards such as N95, FFP2, etc. The flat mask production equipment has stable performance, high output, low defect rate and easy operation.

Machine features

Folding automatic feeding system

1. Aluminum alloy frame, solid and beautiful, to ensure the size of the finished product is accurate;

2. Stainless steel fixture, adjustable from left to right;

3. The tension wheel is set to adjust the fabric tension, so as to effectively ensure the beauty and smoothness of the finished product;

4. Independent nasal line conveying group, convenient for adjustment and maintenance.

Folding and folding forming system

1. Insert folding device, easy to adjust and adjust

2. Large diameter welding wheel can effectively reduce product deformation.

Folding ultrasonic heat sealing system

1. Titanium alloy mould

When most mask machinery manufacturers use aluminum alloy, Lijin mask machine has provided and actively advocates customers to use titanium alloy mold. Compared with aluminum alloy, which is easy to oxidize and burst, is not suitable for long-term rush operation and short service life, titanium alloy has obvious advantages: A. good toughness, suitable for long-term vibration; 2;

B. The thermal / ultrasonic conductivity is strong, so as to ensure the beautiful welding and cutting effect of the product;

C. High hardness, not easy to crack, deformation and rust;

D. Although the cost of titanium alloy is about ten times higher than that of aluminum alloy, titanium alloy die is obviously better than aluminum alloy in terms of overall production benefit. 2. Imported ultrasonic transducer, 20K international frequency standard, output more powerful and stable; plus two sets of ultrasonic system, effectively ensure the welding quality of products.

3. PLC program controls the action of the whole machine to reduce the operation difficulty of users.

Folding discharge system

1. Forming two pieces of products at one time to improve the production speed

2. Product discharge position, automatic stacking, convenient for finishing and stacking of finished products, saving time and labor for ear band welding in the next process.

3. The whole machine has stable performance, continuously adjustable production speed, high production efficiency, up to 160 pieces per minute, convenient and accurate counting, high utilization rate of raw materials, simple and convenient operation and adjustment, high degree of automation, and effective reduction of labor cost.
