The basic structure of a bag-making machine includes: storage device, stepping device, frequency conversion device, whole bag device, heat sealing cutter and control device. The main feature is that the material storage device stores the corresponding amount of raw materials, the stepping device drives the raw materials, the frequency conversion device drives the heat sealing cutter, the whole bag device after the production of fixed bag number, the heat sealing cutter controls its temperature through the temperature controller to seal and cut the raw materials, the control device overall coordination of all aspects of action.

Frequency converter has automatic torque compensation, slip compensation, automatic voltage regulation and other functions. In the case of motor frequent start and stop, it can effectively protect the motor, avoid the impact of starting current on the power grid, and can effectively achieve energy saving and consumption reduction.

The main control process of plastic bag making machine is as follows:

1, open the material switch, through the material storage photoelectric control motor action, to store quantitative materials.

2. Open the heating control switch and heat the hot knife through the temperature controller.

3. The stepper motor drives the raw material to move, and the white bag sealing and cutting is to realize the fixed length control by determining the fixed steps of the stepper motor to stop; Color bag sealing and cutting is to realize positioning control by detecting the corresponding signal to stop the stepper motor.

4. After the stepping motor stops, the three-phase asynchronous motor drives the hot knife to seal and cut.

5, when the sealing and cutting set the number of bags, the whole bag.
