What secrets do you don't know about mask production

Date:2020-09-18

When it comes to masks that are used every day, everyone is familiar with them. But do you know what machines are needed to produce masks? Everyone should see a complete automatic production line. But what kind of machines do those manufacturers use? One of the machines that manufacturers often use to produce their masks is the ultrasonic welding machine. Ultrasonic welding is to convert 50 / 60 Hz current into required electric energy through ultrasonic generator. The converted high-frequency electric energy is converted into the mechanical motion of the same frequency again through the transducer, and then the mechanical motion is transferred to the welding joint.

The welding joint transmits the vibration energy received to the contact surface of the workpiece to be welded. In this region, the vibration energy is converted into heat energy by friction, and the short pressure on the workpiece is maintained after the plastic vibration stops. Solidify into one. Ultrasonic spot welding machine is used for welding of plastic products, spot welding of non-woven fabric, welding of mask ear belt, etc.

The material needed to produce the mask is non-woven fabric. The disposable mask is first made of two layers of non-woven fabric and filter paper. First, the non-woven fabric is hung on the film machine, which cuts the non-woven fabric into a piece of mask. The next step is to use ultrasonic spot welding machine to weld the ear belt rope and mask parts. How does ultrasonic welding work? Ultrasonic welding refers to the surface molecules on the contact surface of the open cover plate and ear band produced by machine welding hair. After a certain amount of pressure is applied, the molecules fuse together, so the mask ear belt rope is welded. After welding, complete the mask.
