In the packaging industry, bag making machines are considered crucial equipment, with their performance and efficiency directly related to the packaging quality and manufacturing efficiency of products. In fast-paced production processes, even minor faults can lead to disruptions, ultimately impacting the entire production chain. Therefore, understanding the common issues of bag making machines and the corresponding resolution techniques is crucial for ensuring continuity and stability in the production process.
A common issue encountered when operating bag making machines is that during startup, the stepper motor emits abnormal sounds and fails to feed the film properly. This frequent fault is generally caused by incorrect orientation of the main motor or problems with the stepper motor driver. To address this, technicians should first ensure that the main motor rotates in the correct direction indicated by the arrow. Additionally, they need to assess the current status of the stepper motor driver. If a fault is detected, consider cutting off the main power and re-energizing the circuit to attempt restoration to normal status. These solutions are primarily based on practical operational experience and guidelines from the bag making machine operation manual.
The accuracy of film feeding size is another common issue in bag making machines, manifesting as variations in the length of the fed film and a significant shortening of the feeding distance compared to the preset size. This type of fault is likely caused by insufficient sensitivity of the photoelectric eye, faults in the photoelectric switch, or inadequate performance of the feeding section. To effectively resolve this issue, technicians should adjust the sensitivity of the photoelectric eye to ensure the correct polarity is selected; replace photoelectric switches with leakage to ground or end-to-end short circuits; and loosen the film pressing strips to check the properties of the feeding section, ensuring that the feeding speed is not slower than the conveying speed. The main references for solving these problems include the bag making machine maintenance guide and experience sharing from technical experts.
A significant challenge encountered during the operation of bag making machines is the reduction in torque of the stepper motor and errors in bag size. This fault may be due to damage to the stepper driver or jamming in the connection between the rubber roller and the stepper motor. To address these challenges, technicians must carefully inspect and repair the stepper driver to ensure stable operation; simultaneously, ensure that the connection between the rubber roller and the stepper motor is smooth and continuous, especially at their junction. These recommendations are primarily based on the stepper motor and driver maintenance guide.
Common issues encountered in the sealing and cutting sections of bag making machines include inadequate sealing, frequent dulling of cold knives, and uneven bag sizes. These problems may be caused by factors such as wear on the sealing knife, faults in the sealing knife circuit board, dulling of the cold cutting knife, or imbalance of the upper and lower blades. To ensure problem resolution, experts need to adjust or replace the sealing knife to ensure its correct position; simultaneously, ensure that the sealing knife circuit board is disconnected and promptly repair or replace the thermocouple; sharpen the dull cold cutting knife and adjust the stability of the blades in the upper and lower directions; finally, adjust the rubber roller to ensure even distribution of bag sizes. These solutions are primarily based on the guidance from the sealing and cutting knife adjustment manual of the bag making equipment.
Apart from the previously mentioned faults, bag making machines may also face conventional issues such as frequent pauses, inability to start the main machine, and slow feeding speed. Possible faults include voltage instability, problems with the servo system and motor, damage to the eye position switch or cam, and faults in components of the feeding speed control circuit board. To solve these problems, technicians should reduce the operating speed of the main machine to ensure voltage stability; simultaneously, ensure that the servo system and motor are functional; additionally, adjust or replace components such as the eye position switch and cam; in the final step, maintain or replace key components such as thyristors or rectifiers in the feeding speed control circuit board. The formulation of these solutions primarily references information from the bag making machine operation guide and maintenance log.
From the above analysis, mastering the common issues and corresponding solutions of bag making machines is crucial for ensuring the stability and continuity of the production process. Regular maintenance checks and prompt handling of faults can significantly reduce the likelihood of production disruptions and enhance overall production efficiency. Furthermore, encouraging technicians to continuously learn and accumulate practical experience constitutes a key path for improving problem-solving capabilities. In practical operations, technical teams need to fully utilize tools such as the bag making machine operation manual, maintenance manual and guide, experience and practice sharing among technicians, as well as the bag making machine operation manual and maintenance log, to more effectively guide fault diagnosis and corresponding resolution measures.
