Tips: Application of stepper motor in packaging machinery

The stepper motor controlled gear pump can achieve precise metering. The gear pump can be used to transport viscous bodies, such as syrup, bean paste, white wine, oil, tomato sauce, etc. The gear pump metering is measured by a pair of gears meshing and rotating, and the material is forced from the feed port to the discharge port through the space between the teeth.

And the power comes from a stepper motor, the position and speed of the hybrid stepper motor's rotation are controlled by a programmable controller, and the measurement accuracy is higher than that of the piston pump. Stepper motors are suitable for running at low speeds. When the speed increases, the noise of the motor will increase significantly.

In a packaging machine that integrates bag making, filling, and sealing, the plastic film for packaging is required to be positioned and supplied at a fixed length. Whether it is intermittent or continuous, it can be completed by a stepper motor.
