A plastic bag-making machine is composed of a storage device, a stepping device, a frequency conversion device, a whole bag device, a hot sealing cutter and a control device. The main characteristic is that the storage device stores the corresponding quantity of raw materials, the stepper device drives the raw material, the frequency conversion device drives the hot sealing cutter, the whole bag device in the production fixed bag number after the whole bag, the hot sealing cutter controls its temperature through the thermostat to seal the raw material, the control device coordinates all aspects of the action.
Inverter using the Taiwan Tatsu M Series inverter. Tatsu M Series inverter with automatic torque compensation, slip compensation, automatic voltage regulator and other functions. The electric motor can be effectively protected under the condition of frequent start and stop, so as to avoid the influence of starting current on the power grid, and can effectively realize energy saving and consumption reduction. The temperature controller adopts the dta4848r. The Daven device has a self-tuning function, and the temperature error is controlled within 0.1 degrees. The main control methods are as follows: 1, open material switch, through the storage of photoelectric control of storage motor action, to store quantitative materials. 2. Turn on the heating control switch and heat the hot knife through the temperature controller. 3, through the stepper motor to drive the raw material movement, in which the white bag seal is to determine the stepper motor to stop the fixed number of steps to achieve fixed-length control; color bag sealing is to detect the corresponding signal to stop stepper motor to achieve positioning control. 4. After the stepper motor stops, the three-phase asynchronous motor drives the hot knife to be sealed. 5, when the number of closures set the bag, the whole bag.
