A plastic bag-making machine mainly consists of a material storage device, a stepping device, a frequency conversion device, an integral bag-making device, a heat sealing knife and a control device. It is mainly characterized in that the material storage device stores a corresponding amount of raw materials, the temperature of the heat sealing knife is controlled by the temperature controller to seal and cut the raw materials, and the control device coordinates all actions as a whole.

Main control modes of plastic bag making machine:

1, turn on the material switch, and control the action of the storage motor through the storage photoelectric to store quantitative materials.

2. Turn on the heating control switch and heat the hot knife through the thermostat.

3. The raw material is driven by a stepping motor, and the white bag sealing and cutting is to ensure that the stepping motor stops walking for a fixed number of steps, so as to realize fixed-length control; Color bag sealing and cutting is to stop the stepping motor by detecting the corresponding signal detected by the electric eye, so as to realize positioning control.

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

5. When the number of bags is set by sealing and cutting, the whole bag is executed.
