The double-layer foil winding machine is a device used for producing foil packaging materials, which can simultaneously wrap two layers of foil paper to produce double-layer foil packaging materials. Double layered foil packaging materials are commonly used for packaging products such as food, medicine, cosmetics, etc., and have the characteristics of good preservation, protection, and aesthetics. The working principle of double-layer foil winding machine mainly includes the following aspects:
1. Basic structure: The double-layer foil winding machine consists of a main unit, foil supply system, foil pressing system, foil cutting system, tension adjustment system, glue coating system, winding system, etc. The host is driven by a transmission device to control the entire packaging process.
2. Foil supply system: The double-layer foil winding machine transports two layers of foil to the workbench through the foil supply system for packaging. The foil supply system ensures smooth conveying and correct positioning of the foil through tension sensors and motor control systems.
3. Foil pressing system: The double-layer foil winding machine places two layers of foil on the workbench and presses them tightly together through the pressing system. The pressing system consists of components such as cylinders and pressure wheels, which can adjust the pressure and pressing time according to the process requirements.
4. Foil cutting system: After the foil is pressed, the double-layer foil winding machine cuts the double-layer foil into the desired size through the cutting system. The cutting system consists of cutting blades, cutting tables, and other components, which can be adjusted according to product specifications and requirements.
5. Tension adjustment system: The double-layer foil winding machine needs to maintain a constant tension on the foil during the packaging process to ensure packaging quality and production efficiency. The tension adjustment system monitors and adjusts the tension of the foil paper through tension sensors and motor control systems to maintain it within an appropriate range.
6. Glue coating system: After the double-layer foil winding machine is pressed and sheared, a layer of glue needs to be applied to the double-layer foil paper to promote tight adhesion. The glue coating system is achieved through components such as glue nozzles and glue rollers, which can adjust the thickness and uniformity of the glue coating according to product requirements.
7. Rolling system: After applying glue, the double-layer foil winding machine rolls the double-layer foil packaging material into rolled products. The winding system is implemented through components such as the winding shaft and tension control system, which can adjust the diameter and tension of the winding according to requirements, ensuring the consistency of the winding quality and diameter.
In summary, the double-layer foil winding machine packages two layers of foil into double-layer foil packaging material through the steps of foil supply, pressing, shearing, tension adjustment, gluing, and winding. Throughout the entire packaging process, the various systems of the equipment work together to ensure the quality and output of packaging materials. The double-layer foil winding machine has the advantages of high automation, high production efficiency, and good packaging quality, and is one of the ideal equipment widely used in industries such as food, medicine, and cosmetics.
