Below we What is the working principle of the non-woven bag making machine?

The working principle of the fully active non-woven bag making machine is to use high-frequency vibration to transmit sound waves from the welding head to the welding surface of the work object, which instantly causes the molecules of the work object to collide and reach the melting point of the plastic. Neatly welded, strong adhesion, using non-woven fabric as the original material, fully automated production, easy to operate. Full-automatic non-woven bag making machine is to feed powder material (colloid or liquid) to the packaging machine from the feeder in real time. In the upper hopper, the introduction speed is controlled by the photoelectric positioning device, and the roll of sealing paper (or other packaging (Data) Driven by the guide roller, it is introduced to the lapel former. After being bent, it is overlapped by the longitudinal sealer to become a cylindrical shape. The material is actively metered and filled into the finished bag, and the horizontal sealer is heat-sealed and cut. The bag tube is pulled down intermittently together to form a three-sided sealing flat bag with overlapping longitudinal seams to complete the sealing of a bag.

The non-woven bag making machine does not use traditional stitching when making non-woven bags, but uses ultrasonic welding technology to reduce the occurrence of joints due to stitching.
