The hot sealing and cutting bag making machine is mainly composed of two motors,which are the main motor and the stepping motor.The main motor is a 220V AC motor.The raw materials produced by the bag making machine are blown cylindrical plastic films.The function of the bag making machine is to cut and seal the raw materials.The products produced are rectangular semi-finished plastic bags 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.
As the hot knife for cutting plastic bags is heated by electromagnetism,the plastic bags are also sealed when the raw materials are cut.The stepper motor is used for feeding.Each time the hot knife is lifted to the time when the hot knife falls,the feeding length is the length of the semi-finished plastic bags produced.
The coordination between the main motor and the stepper motor is very important because the stepper motor can only feed materials when the hot knife is lifted to fall.
