From the perspective of development process, the development of non-woven bag machine is along with social development, market demand, and the continuous development of science and technology. Although the non-woven bag machine is an indispensable equipment in the non-woven bag industry, but in the past, the non-woven bag industry is manufactured by people. This method is not only slow, but also wastes time and labor.
It is precisely because of this, then with the development of science and technology and the promotion of related industries, non-woven bag machine came into being. Since the intelligent equipment was put into production, it not only accelerated the production speed, but also saved people from heavy labor. After further research and exploration, a high degree of automation of non-woven bag making machine is produced, which makes the performance and function of the equipment more perfect, thus creating greater value for enterprises.
With the wide application of non-woven bag making machine, its technology is developing better and better. At present, advanced ultrasonic technology has been widely applied in the non-woven industry. Usually ultrasonic energy belongs to mechanical vibration energy, frequency is more than 18,000 Hz, when applied to bonding thermoplastic materials, such as non-woven fabrics bonding, the usual frequency is 20,000 Hz.
It is precisely because of this characteristic that after the technology development of nonwoven bag making machine transits to the present situation of ultrasonic technology production, compared with the traditional needle-type thread sewing, the present nonwoven bag making machine uses ultrasonic bonding, which not only avoids needles and threads, eliminates thread changing process, but also has no broken thread joint of traditional thread sewing, and can also be used for nonwoven. The cloth is neatly cut and sealed.
Not only that, the ultrasonic technology of non-woven bag machine also has the advantage of improving work efficiency and quality, not only to achieve the sealing edge does not crack, does not hurt the high-quality production of cloth edge, and there is no wool edge, curling phenomenon. At the same time, ultrasonic bonding effectively avoids the degradation of fiber caused by thermal bonding, the influence of adhesive layer on the porosity of materials, and the delamination caused by the impact of liquid.
