Packaging machinery for the material works a batch type and continuous type two.
In the intermittent feeding material, such as in the batch bag packing machine, previously, packaging film feeding the crank connecting rod mechanism of intermittent drawstring way, not only the structure is complex, and difficult adjustment. If the drive belt wheel with AC servo motor, can be preset distance running AC servo motor, each run time and stop at the controller in time, using good acceleration of AC servo motor and positioning performance, to achieve accurate control of film feeding length objective. Especially in the control system of color correction device, deviation of the signal through the color detecting switch detects, the controller is transported to the AC servo motor, acceleration performance and excellent control precision AC servo motor, can make the deviations are fast and accurate correction. In the continuous feeding material, excellent acceleration performance of AC servo motor and its overload capacity, can ensure continuous uniform feeding material.
