Its core solution is to address the problem of microbial contamination in traditional packaging, thereby extending the shelf life of the contents.

[0003] Currently, the antibacterial treatment of plastic packaging bags mainly uses chemical spraying methods, but this has the following problems:

[0004] 1) Chemical coatings can easily lead to uneven distribution of antibacterial agents and may leave harmful residues;

[0005] 2) Existing devices are mostly single-processing modes and cannot combine multiple antibacterial methods to achieve synergistic effects. Therefore, we propose an antibacterial treatment device for plastic packaging bags. Utility Model Content

[0035] Reference Figures 1-4 An antibacterial treatment device for plastic packaging bags is provided. This antibacterial treatment device for plastic packaging bags includes a sealed treatment chamber 1. A material inlet 101 is opened on one side of the sealed treatment chamber 1 and a material outlet 102 is opened on the other side of the sealed treatment chamber 1. When in operation, the plastic packaging bags to be antibacterially treated are conveyed by an external conveying mechanism and enter through the material inlet 101 and exit through the material outlet 102.

[0036] An ultrasonic atomizer 2 is installed inside a sealed treatment chamber 1. The ultrasonic atomizer 2 is connected to an antibacterial agent storage tank 3 via a connecting pipe. The antibacterial agent storage tank 3 is also installed inside the sealed treatment chamber 1. The ultrasonic atomizer 2 is used to atomize the liquid antibacterial agent into micron-sized particles. The ultrasonic atomizer 2 uses an ultrasonic atomizing plate array, and a guide plate 201 is provided at the outlet of the ultrasonic atomizer 2. The guide plate 201 is spiral-shaped to form a vortex airflow, which facilitates the atomization of the antibacterial agent and its penetration onto the plastic packaging bag to be treated with antibacterial agents to achieve physical sterilization. At the same time, the design of the guide plate 201 allows the antibacterial agent to form a vortex diffusion. Combined with plasma surface modification, this improves the adhesion and distribution uniformity of the antibacterial agent.

[0037] Plasma generator 4 is installed on the top of the sealed processing chamber 1. Plasma generator 4 is used to generate low-temperature plasma to cover the surface of the packaging bag. Plasma generator 4 is of dielectric barrier discharge type. The motors are arranged in a comb-like staggered pattern to facilitate the generation of low-temperature plasma to cover the surface of the packaging bag in order to achieve chemical sterilization.

[0038] Temperature control module, the temperature control module is used to regulate the internal temperature of the sealing chamber 1, the temperature control module includes an infrared heater 5 and a temperature sensor 6 installed in the sealing chamber 1, so as to regulate the internal temperature of the sealing chamber 1;

[0039] The control unit is electrically connected to the ultrasonic atomizer 2, the plasma generator 4, and the temperature control module. The control unit is used to regulate the atomization amount of the ultrasonic atomizer 2 and the plasma intensity of the plasma generator 4. The control unit is equipped with a human-machine interface 701 installed on the sealed processing chamber 1. The human-machine interface 701 supports preset antibacterial agent concentration, processing time, and multiple process formulas. In application, it can be adjusted through multi-parameter linkage to adapt to packaging bags of different thicknesses and materials.

The waste liquid recovery tank 10 is coated with a hydrophobic membrane for separating the unattached antibacterial agent. When in operation, the waste liquid recovery tank 10 is located below the plastic packaging bag to be antibacterial treated, so as to facilitate the recovery of waste liquid.

[0042] In actual use, the temperature inside the sealed treatment chamber 1 is heated to the specified temperature by the infrared heater 5. Then, the concentration of antibacterial agent, treatment time and process formula are preset using the human-machine interface 701. The plastic packaging bag to be antibacterial treated enters through the material inlet 101 and exits through the material outlet 102, and is simultaneously conveyed by an external conveying mechanism. At this time, the waste liquid recovery tank 10 is located below the plastic packaging bag to be antibacterial treated. At the same time, the ultrasonic atomizer 2, plasma generator 4 and HEPA filter 9 are activated. The ultrasonic atomizer 2 atomizes the liquid antibacterial agent into micron-sized particles, which penetrate into the plastic packaging bag to be antibacterial treated. The plasma generator 4 generates low-temperature plasma to cover the surface of the packaging bag to achieve physical and chemical sterilization. The HEPA filter 9 circulates and filters the sealed treatment chamber 1. During this period, the waste liquid recovery tank 10 plays a role in recovering waste liquid, which facilitates the physical and chemical sterilization of the plastic packaging bag and improves the adhesion and distribution uniformity of the antibacterial agent.
