The bag making machine is a machine for making various plastic packaging bags or other material packaging bags. The processing range is various kinds of plastic bags or other materials with different thickness and thickness. Generally, plastic packaging bags are the main products.
Plastic bag making machines have developed rapidly. Since the 1990s, there has been great progress in technology. In addition to the increasingly sophisticated auxiliary functions, production speed and high efficiency are important aspects, especially in electrical aspects. Therefore, the performance of the machine has indeed made great progress, which is the development direction.
The improvement of the function of the bag making machine is mainly in the control part, such as the adjustment of the length of the bag, the adjustment of the color mark detection, and the improvement of the production speed. In the past, it was all adjusted by hand. If the length adjustment must be carefully adjusted to the value of the eccentricity of the crank mechanism, then open the mechanism bag, check the sample length, repeated several times, more troublesome. Moreover, since it is intermittent reciprocating motion, the machine vibration is large. If the stepping motor is used to directly drive the rubber roller for intermittent reciprocating operation, the number of pulses is controlled by the electric circuit to control the length of the working time of the motor. The fixed length of the film can be delivered with minimal error, which eliminates the need for a crank-link mechanism and facilitates lengthening, eliminating the need for electromagnetic clutches, brakes or overrunning clutches, as well as complex and expensive electronic control systems.
