Description

Technical Field

[0001] This utility model relates to the field of medical packaging film, and in particular to a folding mechanism for a composite film bag making machine. Background Technology

[0002] The folding mechanism of a composite film bag making machine is a key component in the production of medical packaging films. Its folding precision, aseptic control capability, and adaptability to the production process directly determine the sealing performance, aseptic level, and production efficiency of medical composite film packaging bags, thereby affecting the storage safety and clinical reliability of pharmaceuticals, medical devices, and other products. It is an important link in ensuring that medical packaging meets standards.

[0003] Traditional composite film bag making machines often employ a single mechanical folding structure in their folding mechanism, lacking a targeted aseptic disinfection design. This makes them prone to microbial growth or cross-contamination on the film surface during folding, resulting in substandard sterility of the final packaging. Furthermore, the disinfection residue treatment in traditional mechanisms is disconnected from the folding and sealing processes. Some mechanisms using a single disinfection method also pose a risk of excessive residue. These shortcomings make it difficult for traditional folding mechanisms to meet the modern medical packaging's production demands for high efficiency, sterility, precision, and multi-specification adaptability. This restricts their application in high-end medical packaging fields such as pharmaceutical aluminum-plastic bags and affects the professionalism and safety of medical packaging production.

[0004] Therefore, those skilled in the art have provided a folding mechanism for a composite film bag making machine to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a folding mechanism for a composite film bag-making machine. This mechanism integrates dual disinfection, precise folding, and edge sealing and drying, solving the problems of incomplete disinfection, irregular folds, and uncontrollable residues in traditional folding mechanisms. A dual disinfection process is achieved through an ultraviolet disinfection device and a hydrogen peroxide vaporization nozzle. This first pre-kills microorganisms on the film surface before deep sterilization, meeting medical aseptic standards. The folding plate, in conjunction with folding rollers, guides and shapes the film using inclined surfaces, ensuring neat and consistent folds and improving packaging regularity. A pre-sealing and subsequent drying process is employed. After the sealing machine uses a telescopic rod to push the heating plate to achieve a tight seal, hot air is generated in the drying and decomposition chamber to decompose hydrogen peroxide residue and dry the film, ensuring sealing stability. Multiple sets of conveyor rollers work together to maintain stable film tension, adapting to different thicknesses of medical packaging films. This machine is suitable for medical applications such as pharmaceutical aluminum-plastic bags and medical device packaging, achieving integrated and efficient production of folding, disinfection, and edge sealing, improving the safety and production efficiency of medical packaging.

Through the above technical solution, the third conveying roller in front of the sealing table is driven by a rotating motor to pull the sealed film material stably, ensuring smooth conveying of finished products and maintaining the continuity of the production process.

[0010] Furthermore, a vaporization nozzle is fixedly installed on the mounting bracket, and the output end of the extraction pump is fixedly connected to the vaporization nozzle; Through the above technical solution, the vaporization nozzle on the mounting frame is connected to the output end of the extraction pump, which can vaporize the extracted hydrogen peroxide solution into droplets, uniformly cover the surface of the membrane material, achieve deep disinfection, and meet the sterile requirements of medical packaging.

[0011] Furthermore, a heating unit is fixedly installed on the drying and decomposition chamber; Through the above technical solution, the heater on the drying and decomposition chamber can generate hot air, which can decompose the hydrogen peroxide remaining on the surface of the film material and quickly dry the film material, avoiding moisture from affecting the sealing performance and ensuring the stability of medical packaging.

[0019] Working Principle: The operator first installs the medical composite film roll onto the raw material placement roller 14. The film is pulled and unfolded from the raw material placement roller 14, and first passes through the ultraviolet disinfection device 21. Under ultraviolet irradiation, surface microorganisms are initially killed, completing pre-disinfection to ensure the initial sterility of the medical packaging. Subsequently, the film is conveyed to the folding plate 16 at the top of the support frame 15. Guided by the inclined surface of the folding plate 16, it is gradually folded into the preset shape of the medical packaging bag. Then, the folding roller 2 rolls the folded film to assist in shaping, ensuring that the folded edges are neat and consistent. The shaped film continues to be conveyed forward, passing through the first conveying roller 4 and the second conveying roller 5 in sequence, maintaining a stable tension as it enters the next process. When the film reaches the mounting frame 18, the extraction pump 20 is started, drawing medical-grade hydrogen peroxide solution from the hydrogen peroxide storage tank 22. The solution is vaporized into micron-sized droplets through the vaporization nozzle 17, evenly covering the inner and outer surfaces of the film, using strong oxidizing properties to kill residual microorganisms and achieve deep disinfection. The film material is then conveyed to the sealing table 6. The telescopic rod 13 of the sealing machine 11 pushes the heating plate 12 closer to the edge of the film material. The edge of the bag is sealed by heating and pressing, ensuring that the packaging barrier meets medical standards. The sealed film material then enters the drying and decomposition chamber 7. The sterile hot air generated by the heater 10 circulates in the chamber, which can decompose the residual hydrogen peroxide into harmless water and oxygen, and quickly dry the film material to avoid moisture affecting the sealing effect. Finally, the sterilized medical packaging bag is pulled to the third conveyor roller 9. Driven by the rotating motor 8, the third conveyor roller 9 smoothly sends the finished product out of the operating table 1. Throughout the process, the support leg 3 firmly supports the operating table 1, ensuring that all components work together to produce a medical composite film packaging bag that meets sterility requirements.
