Analysis of The Wrapping Process of Transparent Film Three-dimensional Packaging Machine

The coating process of the transparent film three-dimensional packaging machine revolves around the conveying, forming, sealing and cutting of the transparent film. The following is a specific analysis:

Film material conveying: As the main material of the packaging machine, the transparent film needs to be conveyed to the packaging position at a constant speed and tension through the film material conveying system (such as rollers or conveyor belts). This process needs to be precisely controlled to ensure that the film material is flat and free of wrinkles, providing a good foundation for subsequent molding and packaging.

Forming process: In the forming area, the transparent film is stretched and folded through pneumatic or mechanical devices to adapt to the three-dimensional shape of the items to be packaged. This process requires the cooperation of a high-precision control system and mechanical components to ensure that the packaging adheres closely to the items while maintaining its aesthetic appeal. For example, the upper and lower film cylinders, the left and right film cylinders and the heating device work together to form the film in the predetermined shape.

Sealing process: After the transparent film is formed, the items are wrapped, and then the two ends or sides are sealed by heat sealing, cold sealing or adhesive, etc. The heat sealing process requires precise control of temperature and pressure to ensure a firm and sealed seal. Cold sealing is suitable for temperature-sensitive items to prevent temperature changes inside the box.

Cutting process: After the packaging is completed, the product needs to be cut to the required length through a cutting device. The cutting device is composed of a cutting heating device, cutting wheels and cutting rollers, etc., ensuring accurate cutting positions, moderate speeds, and maintaining the consistency and integrity of each packaging unit.

Process characteristics:

Local low-temperature sealing: Unlike heat shrink packaging machines, transparent film three-dimensional packaging machines use local point instant low-temperature sealing to prevent temperature changes inside the box. They are suitable for medicines, heat-sensitive electronic products, etc.

High-precision control: The entire process flow requires the support of a high-precision control system to ensure the accuracy of film material conveying, molding, packaging and cutting.

High degree of automation: The equipment is equipped with functions such as automatic feeding, automatic counting, and fault indication, reducing manual intervention and enhancing production efficiency.
