The machine adopts advanced computer control system, Weilun LCD display, Delta PLC and servo drive. The whole machine adopts frequency conversion speed regulation, and uses engineering devices such as high band ultrasonic heat sealing principle welding, ultrasonic rolling welding, ultrasonic rolling bottom welding, etc. The photoelectric tracking automatic correction, dual material magnetic powder brake, automatic shutdown without material, automatic counting alarm, non-woven fabric material is an environmentally friendly material and a trend in the future market. At present, manufacturers all use manual production, which results in high production costs and low market competition. The other advantage of this bag making machine is its high degree of automation, greatly improving production efficiency and reducing product costs.
