What Is The Difference Between Non-woven Vest Bag Making Machine Technology And Ordinary Bag Making Machine Technology?

Oct 26, 2021



The non-woven t-shirt bag making machine is a kind of t-shirt bag making machine. We must first analyze its operation principle and technology during use. We also need to be familiar with and understand its technology. Let’s talk about it below. What is the difference between non-woven vest bag making machine technology and ordinary bag making machine technology?

Compared with the traditional t-shirt bag making machine, the non-woven t-shirt bag making machine adopts ultrasonic bonding, no needle thread, eliminating the need for the thread changing process, and without the traditional thread breakage, it can also carry out the non-woven fabric. Neatly partial shearing and sealing. The working speed is fast, the sealing edge is not cracked, the cloth edge is not damaged, and there is no burr and curling phenomenon. At the same time, ultrasonic bonding effectively avoids the degradation of fibers by thermal bonding. The quality of the bonding layer affects the porosity of the material, and delamination occurs after being impacted by the liquid.

 

Ultrasonic bonding equipment is mainly composed of an ultrasonic generator and a roller. The main components of the ultrasonic generator are the horn, power supply and transformer. The horn, also called the radiator, accumulates sound waves on a flat surface; the roller, also called the anvil, is used to collect the heat released from the horn of the ultrasonic generator. The bonding material runs continuously between the "horn" of the ultrasonic generator and the roller, and is combined with a relatively low electrostatic force. The frequency converter converts electric energy into high-frequency electric energy, and then converts the electric energy into an ultrasonic oscillator, which converts vibration energy into vibration energy. The vibration energy is amplified by the amplification system (intensifier) and transmitted to the horn corner. The acoustic tool immediately comes into contact with the material to be bonded. These super-acoustic frequencies cause mechanical pressure between the material molecules, release heat, break the bond of the molecules in the material, make the material melt at the bonding point, and then combine two or more layers of materials together by mechanical pressure.
