Detail medical face mask machine



Detail medical face mask machine

Medical face mask

Most of the masks we usually wear are medical face masks. These masks have good protection against viruses. Medical face masks are mainly produced by Medical Face Mask Making Machine. Today we will talk about the relevant knowledge of medical face mask machines in detail.

Mainly divided into body machines and earband welding machines. The former is also known as the punching machine, and the latter can be divided into several different types of mask machines: ultrasonic mask inner ear strap automatic welding machine, ultrasonic mask outer ear strap automatic welding machine, ultrasonic strap mask ear strap welding machine.

1. Working principle

The working principle of this type of medical mask machine is to use ultrasonic waves to instantly generate waves to quickly weld or trim and emboss the material, which is more stable and saves labor and time.

2. Detailed classification

1. Mask body machine

The main body machine is mainly used for automatic production, which can produce 1-4 layers of PP spun-bond non-woven fabrics, activated carbon, and filter materials for masks. It belongs to a line of automated operations. According to different raw materials, different usage standards can be produced.

2. Ultrasonic inner ear mask machine

 The ultrasonic welding method is mainly used. When the mask is moved to the processing position, ultrasonic waves are automatically generated, and then vibration is formed on the earband, which is instantly converted into heat, thereby melting the material to be processed, so that the earband can be firmly attached to the mask. On the inside of the body, this is also the last processing step in the production of the inner ear mask.

3. Automatic spot welding machine for outer ear mask

This part is mainly to fuse the elastic band to the two outer sides of the mask body by ultrasonic and then complete the finished product of the ear strap mask. Only a worker is required to put the mask body piece by piece on the conveyor belt, and the other steps are all The machine works automatically, which is more convenient.

4. Ultrasonic strap mask ear strap welding machine

It mainly adopts the ultrasonic welding method. The mask conveying device is set up on the machine in advance, and the semi-finished product of the mask is input into the conveying device, and then it is wrapped by the drawing tube, and after the ultrasonic flower wheel is pressed, the bandage is cut off, and then the finished product is output.

3. How to use medical face masks?

It should be more common for us to use medical face masks in ordinary times, and the method of use is relatively simple. It is enough to know which side is the inner side of the mask and which side is the outer side of the mask. The things that are wrapped and all-plastic lines on the medical face masks are flat.

You can wear it on the front and back, and then you can wear it according to your face shape.

What are the types of medical mask machines?

Medical mask machines can be divided into body machines and earband welding machines. Among them, the body machine is called the ultrasonic plane mask machine, and the band welding machine can be divided into ultrasonic inner ear mask machine, ultrasonic outer ear mask machine, ultrasonic strap mask machine, produced by different types of mask machines Masks are also suitable for different groups of people and environments. Today, the editor will introduce to you in detail the categories of medical mask machines:

1. About the main body of the ultrasonic mask

Because the ultrasonic mask body machine is mainly used for the automatic production of multi-layer material flat mask finished products, generally 1-4 layers of PP spunbond non-woven activated carbon and filter materials can be used. The nose wire is inserted, then the edge is sealed, and the finished product is cut in one line. Depending on the raw materials used, different standards such as N95 masks can be achieved.

2. About the ultrasonic inner ear mask machine

The ultrasonic inner ear strap mask machine mainly adopts the ultrasonic welding method. When the mask is moved to the processing position, the ultrasonic wave will be automatically generated at this time, forming micro-amplitude and high-frequency vibration on the rear strap, and instantly converted into heat, so as to melt the material to be processed.

3. About the ultrasonic outer ear mask machine

It has the following features:

  1. The ultrasonic outer ear mask machine, it is small in size and occupies a small space;
  2. Secondly, it is controlled by the PLC program, the stability is high, and the failure rate is low;
  3. The machine of the ultrasonic outer ear mask machine is mainly made of aluminum alloy structure, which is beautiful and sturdy and does not rust;
  4. Photoelectric detection is adopted to reduce the error rate;
  5. The welding strength of the rear strap can be adjusted.

4. Ultrasonic Bandage Mask Machine

The ultrasonic mask strapping machine adopts the method of ultrasonic welding. The conveying device is set up on the machine in advance, and then the semi-finished mask is input from the conveying device. The upper strap is cut off to output the final product. The attractive point is that only one person can put the mask body on the conveyor belt of the machine, and the rest of the follow-up work can be completed automatically. Save manpower and material resources to a great extent.

The above is the whole content. There are many types of mask machines for medical face masks, but they still need maintenance during use, so as to prolong their service life. Hope this brief introduction can help you!
