The China small dc motor manufacturers tells you about the use of DC motors in packaging machinery
There are two kinds of working methods of packaging machinery supply materials: intermittent and continuous.
In the intermittent material delivery mode, such as on the intermittent bag packing machine, before, the packaging film supply used the intermittent pull belt of the crank connecting mechanism, not only the structure is complex, but also difficult to adjust. If the DC motor is used to drive the pulley wheel, the distance, running time, and pause time of each DC motor can be set in advance in the controller, and the excellent acceleration and positioning performance of the DC motor can be used to achieve the accurate control of the length of the film supply. Especially in the control system with colored Mark correction device, the deviation signal detected by the color Mark detection switch is transported to the DC motor by the controller. The excellent acceleration performance and control accuracy of the DC motor can make the deviation be corrected quickly and accurately. In the continuous supply mode, the excellent acceleration performance of DC motor and its overload ability can ensure the continuous uniform delivery of materials.
