Scientific Development and Technological Innovation of Bag Making Machines

Overseas, the advancement of plastic bag making machines has been rapid, with significant technological advancements since the 1990s. Not only have various auxiliary functions improved, but there has also been a strong focus on enhancing production speed and efficiency, particularly in terms of electrical aspects. The widespread utilization of microelectronics technology has played a crucial role in pushing the machine's performance to new heights. Undoubtedly, this progress signifies the clear direction of development in this field.

 

Improving the bag making machine's functionality is crucial, especially in the control part. Previously, adjustments were manual, but with advanced technology, it's possible to adjust the bag's length easily and accurately by controlling the pulse number through electrical circuits. This is achieved by using a stepper motor to drive the rubber roller, which controls the bag's intermittent reciprocating operation. The advantage of this method is that it saves a set of crank connecting rod mechanisms and eliminates the need for electromagnetic clutch, brake and overrunning clutch, plus it is cost-effective. In addition, it increases production speed and reduces vibration, enhancing efficiency and productivity. Overall, technology has revolutionized bag making machines, making them more efficient and easier to adjust and operate.

 

To optimize the functionality of the stepper motor (like 130BC3100), it is advisable to incorporate a dedicated stepper motor controller (such as YXD-2) and a stepper motor driver. This combination enables centralized control of various electrical buttons. With the help of a convenient dialer on the control panel, it becomes effortless to adjust parameters like bag making length and other operational settings. These settings encompass essential components such as the machine stop button, discharge amount (controlled by discharge contact), color code photoelectric probe switch, machine main switch, welding knife temperature, counter, and more. By integrating all these elements, the overall control and efficiency of the stepper motor system are significantly enhanced.

 

The transmission part of the main shaft is rotated by the main motor, which is equipped with a special cam (optical disc) providing signals for the start and stop of the stepper motor. By working in harmony with various predetermined requirements, the machine efficiently carries out bag making operations including sealing, cutting, conveying, and color coding.

 

This bag making machine boasts an impressive production speed, capable of reaching 140~150 times/minute. It excels in precision as well, with a small bag length error of only about 0.5~1mm and a maximum bag length of ≤ 1000mm. Compared to ordinary photoelectric control bag making machines, this machine is undoubtedly more efficient in creating high-quality bags at a faster rate.

 

With the production of all electrical component control instruments in China, bag making machine manufacturers can benefit from the convenience and affordability of specialized suppliers. These components, including photoelectric probe switches such as the Futai photoelectric probe, are readily available as standalone products or as part of a complete set. The ability to source these components independently allows for better overall machine performance and promotes technological progress in the bag making machinery industry. By utilizing these specialized products, manufacturers are better equipped to produce more advanced and innovative bag making machines.
