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

The working principle of the fully active non-woven bag making machine is to use high-frequency vibration from the welding head to transmit sound waves to the fusion surface of the working material, instantly causing the working material molecules to collide and reach the plastic melting point. Then, the solid material is quickly dissolved, and the textile can be neatly welded with strong adhesive force. Using non-woven fabric as the raw material, the machine is fully active and easy to operate. The fully active non-woven bag making machine is a feeding machine that delivers powder (colloids or liquids) to the packaging machine in real time. The feeding speed is controlled by the photoelectric positioning equipment. The rolled sealing paper (or other packaging materials) is driven by the guide roller to the lapel forming machine, which is bent and then overlapped into a cylindrical shape by the longitudinal sealing device. The material is actively measured and filled into the bag. The transverse sealing device intermittently pulls the bag cylinder downwards during the heat sealing and cutting process, forming a flat bag with three sides of overlapping longitudinal seam sealing, and completing the sealing of a bag.

When making non-woven bags, the non-woven bag making machine does not use traditional stitching, but uses ultrasonic technology for welding, reducing the occurrence of joints due to stitching. In addition, the non-woven bag making machine adopts advanced technology for processing, which will not harm the fabric during the processing and will not cause problems such as burrs and curls.
