In the packaging industry, the side-sealing bag making machine is a key equipment for producing various types of packaging bags. With the continuous improvement of the market's requirements for packaging bag production efficiency, the high-speed operation of the side-sealing bag making machine has become an inevitable trend. However, under high-speed operation, how to maintain edge sealing accuracy has become an important issue that companies need to solve urgently.Equipment inspection and maintenance are the basisBefore high-speed operation, it is essential to conduct a comprehensive inspection of the side-sealing bag making machine. It is necessary to carefully check whether the conveyor belt, heat sealing knife, positioning device, sensor and other components are intact. Once the components are found to be damaged or worn, they should be replaced or repaired immediately. For example, the conveyor belt speed is a key factor affecting the packaging effect. Too fast speed will cause the packaging to be unstable and easy to break, and too slow speed will reduce production efficiency. Therefore, according to the product characteristics and packaging requirements, the conveyor belt speed should be appropriately adjusted through the buttons or knobs on the control panel.Regular maintenance is also indispensable. To clean the surface of the machine, wipe it with a clean soft cloth. For hard-to-clean parts, use compressed air to blow; clean the edge banding conveying channel to ensure smooth passage of the edge banding; add appropriate amount of lubricating oil or grease to the transmission parts such as gears, chains, and guide rails according to the requirements of the equipment manual to reduce wear and keep the equipment running smoothly. At the same time, it is necessary to regularly check the wear of each component, replace wearing parts, lubricate the transmission parts, and regularly calibrate and adjust the edge sealer to ensure its accuracy and stability.Adjustment of process parameters is the keyThe temperature of the heat sealing knife is one of the key factors affecting the heat sealing effect. Too high temperature will cause the bag or box to deform or burn, and too low temperature will cause the heat seal to be weak. According to the type and thickness of the packaging material used, the temperature of the heat sealing knife should be appropriately adjusted through the temperature regulator on the control panel.The positioning device should ensure that the product is accurately positioned on the conveyor belt so that the heat sealing knife can accurately seal the bag or box. If the positioning is inaccurate, the product position will be offset, affecting the packaging effect. Therefore, the position and height of the positioning device should be appropriately adjusted according to the size and shape of the product.The sensor is used to detect the position and status of the product. Its insufficient sensitivity may cause the machine to misjudge or miss the judgment, affecting the packaging effect. According to the product characteristics and packaging requirements, the sensor sensitivity should be adjusted appropriately through the setting button on the control panel.Operation and monitoring are guaranteesThe operator should be familiar with the operating procedures of the side-sealing bag making machine and operate strictly in accordance with the operating procedures to avoid misoperation that may cause equipment damage or reduced edge sealing accuracy. During the processing, the operating status of the equipment should be closely observed to promptly detect and deal with abnormal conditions, such as excessive noise and abnormal vibration.Use measuring tools such as calipers and micrometers to regularly measure the dimensions of the edge-sealed packaging bags and check whether the edge sealing accuracy meets the requirements. Establish quality inspection records, track and analyze the edge sealing accuracy, promptly detect the trend of reduced accuracy, and take corresponding measures to adjust it. If the edge sealing accuracy is found to be reduced, the side sealing machine should be adjusted in time. The adjustment should be performed by professional technicians to ensure the accuracy and effectiveness of the adjustment.To maintain the edge sealing accuracy of the side-sealing bag making machine at high speed, it is necessary to start from multiple aspects such as equipment inspection and maintenance, process parameter adjustment, operation and monitoring. Only by doing these things well can we ensure that the side-sealing bag making machine can stably produce high-quality packaging bags at high speed to meet market demand.
