Composition and control method of plastic pouch making machine
- Oct 13, 2018 -

A plastic pouch making machine mainly includes components such as a storage device, a stepping device, a frequency conversion device, a whole bag device, a heat sealing cutter and a control device. Wherein, the storage device is used for storing a 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 is in the whole bag after the number of fixed bags is produced, and the heat sealing cutter controls the temperature to the raw material through the temperature controller. Sealing and cutting, the control device as a whole coordinates all aspects of the action.


The frequency converter of the plastic pouch making machine has the functions of automatic torque compensation, slip compensation, automatic voltage regulation, etc. It can effectively protect the motor in the case of frequent start and stop of the motor, avoiding the influence of the starting current on the power grid, and can be effective at the same time. Achieve energy saving and consumption reduction.


The thermostat of the plastic pouch making machine has a self-tuning function, and the temperature error is controlled within 0.1 degree. When controlling, first open the discharge switch, and control the operation of the storage motor through the storage photoelectric to store the quantitative materials. Then turn on the heating control switch and warm the hot knife through the thermostat.


Then, the stepping motor drives the raw material action, wherein the white bag sealing and cutting is to determine the stepping motor to stop the fixed number of steps to achieve the fixed length control; the color bag sealing and cutting is to realize the positioning control by detecting the electric signal to detect the corresponding signal to stop the stepping motor. When the stepping motor of the plastic bag making machine stops, the three-phase asynchronous motor drives the hot knife to seal and cut; when the number of bags is sealed and cut, the whole bag is carried out, thereby completing a complete bag making process.
