What are the innovative points of the heat sealing process for infusion pressure bags

The innovation of the heat sealing process of infusion pressure bags mainly lies in equipment optimization, process parameter control, automation and intelligence, as well as cooling and positioning design. The following is a specific analysis:

Equipment optimization and efficient heat-sealing technology:
In the heat-sealing production of infusion pressurized bags, it is crucial to adopt efficient heat-sealing technology. For example, by optimizing the design of the heating device, such as using evenly distributed heating rods, the heat distribution in the mold is ensured to be even, so that the film material is heated evenly, thereby improving the quality of heat-sealing welding.
Introducing advanced heat-sealing equipment, such as devices equipped with auxiliary heat-sealing mechanisms and active discharging mechanisms, to realize automatic feeding and heat-sealing processes, reduce manual operations, and improve production efficiency.
Process parameter control and optimization:
Process parameters (such as heat-sealing temperature, heat-sealing time, and heat-sealing pressure) have a significant effect on heat-sealing strength. Through orthogonal or DOE experiments, the heat-sealing strength under different conditions is tested, and the optimal parameter combination is selected to ensure the heat-sealing quality.
Introducing temperature feedback devices such as thermocouples to monitor the heating temperature of the heating device in real time, it is convenient to control the heating device in a timely manner, and avoid poor heat-sealing or film material damage caused by excessively high or low temperatures.
Automation and intelligence:
With the development of automation and intelligent technology, the heat-sealing process of infusion pressurized bags is gradually developing in the direction of automation and intelligence. For example, by introducing an automated control system, the heat-sealing process can be automated and the impact of human factors on the heat-sealing quality can be reduced.
Intelligent technologies, such as machine vision and artificial intelligence algorithms, can be used to monitor and control the heat-sealing process in real time, timely discover and correct problems in the heat-sealing process, and improve product quality and production efficiency.
Cooling and positioning design:
In the heat-sealing process, in order to prevent the bag from being deformed by heat, a cooling device needs to be set up to cool the bag part that does not need to be welded. For example, cooling by circulating cooling water is low-cost and effective.
Positioning parts, such as the first positioning part and the second positioning part, are used in the mold design to facilitate the rapid positioning of the upper and lower molds during installation, while avoiding direct contact between the molds, reducing friction, and increasing the service life of the molds.
