Bag making machine is generally composed of electrostatic elimination device, cutting system, sealing welding knife, optical control feeding device and mechanical transmission. The integrated production requires the design of the transmission structure to be more flexible and efficient. Therefore, let's first take a look at the transmission structure of the bag making machine what kind of characteristics.

The optical control feeding device is composed of servo motor, steel feeding roller, photoelectric tracking device and electric control line. Its function is to ensure the normal delivery of film by the machine in the production process. When the machine is running, when the film feeding speed is too fast and the optical ray is covered, the device will instruct the servo motor to stop and stop the feeding, so that the automatic feeding can be achieved repeatedly.

General sealing and cutting bag making machine is driven by the main motor disc speed change device, and then through the crankshaft connecting rod and other transmission mechanism to the executive mechanism. The stepless speed regulating handwheel of disc is under the operating table. The handwheel is rotated clockwise to slow the machine operation and counterclockwise to increase the speed.

The rise and fall of sealing and cutting bag making machine transmission device, is the one with the eccentric shaft is set on the machine, the eccentric pivot set a parallel mechanism with a connecting rod, parallel institutions consist of before and after swinging arm and moving pole, before and after each pivot in the swing arm set on the machine, and before and after the back-end swing arm is the pin joint before and after the lift shaft, and the other end of the swing arm respectively before and after pin joint in the ends of the moving plate, cutting bag or sealing bag cross frame on the upper and lower lifting shaft, when the shaft actuation, eccentric drive before and after swing, swing arm through before and after the lift shaft and into the upper and lower displacement, cut the bag or under the seal device in the machine up and action.
