Non woven bags are loved by many consumers. Due to the increasing demand for non-woven bags, many manufacturers choose to produce non-woven bags. Due to the high labor cost of manual sewing and the lack of machine made neatness, errors often occur, which is why non-woven bag making machines have emerged. What is the working principle of 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 fusion surface of the workpiece, instantly causing the molecules of the workpiece to collide and reach the melting point of the plastic. Then, the solid material is quickly dissolved, and the textile can be welded neatly with strong adhesion. Using non-woven fabric as the raw material, the machine is fully active in production and easy to operate. The fully active non-woven bag making machine is a feeder that delivers powder (colloid or liquid) to the packaging machine on time In the hopper above, the introduction speed is controlled by a photoelectric positioning device. The rolled sealing paper (or other packaging materials) is driven by a guide roller and introduced into the lapel former. After being bent, it is overlapped into a cylindrical shape by a longitudinal sealer. The material is actively measured and filled into the finished bag. The transverse sealer intermittently pulls the bag cylinder downwards while performing heat sealing and cutting, finally forming a flat bag with overlapping longitudinal seams on three sides, completing the sealing of a bag.
When making non-woven bags with a non-woven bag making machine, traditional stitching is not used, but ultrasonic welding technology is used to reduce the occurrence of joints due to stitching. In addition, the non-woven bag making machine adopts advanced technology for processing, which will not damage the fabric or cause problems such as burrs and curled edges during the processing.
