How does the garbage bag making machine work?

During the working process of the garbage bag making machine, we need to understand the working principle of the garbage bag making machine, which is helpful for us to use the garbage bag making machine.
   The garbage bag making machine is mainly composed of two motors, the main motor and the stepping motor. The main motor is a 220V AC motor, and the raw material produced by the bag making machine is a blown cylindrical plastic film. The function of the bag making machine is to cut and seal raw materials. The product produced is a rectangular semi-finished plastic bag with a certain length and sealed at both ends. The main motor is used to drive the hot knife of the machine to cut raw materials. Since the hot knife for cutting the plastic bag is heated by electromagnetic, the plastic bag is sealed while cutting the raw material, and the stepping motor is used for feeding. The feeding is carried out when the hot knife rises to the time the hot knife falls, and the length of each feeding is the length of the semi-finished plastic bag produced. Since the stepper motor can only feed when the hot knife is lifted and blanked, the coordination of the main motor and the stepper motor is very important.
