Working Principle and Application of Continuous Belt Rolling Vacuum Packaging Machine

Continuous Belt Vacuum Packaging Machine is an efficient packaging equipment that achieves product packaging by heating and softening the packaging material, and then tightly adhering it to the surface of the product using vacuum suction. This packaging method can not only effectively protect the product from damage during transportation and storage, but also improve the shelf life of the product.

Working Principle of  Continuous Belt Rolling Vacuum Packaging Machine:

1. Packaging Process: Firstly, place the product to be packaged on the workbench of the vacuum packaging machine, and then use a heating device to heat the packaging material to a certain temperature to soften it. Next, start the vacuum system and use vacuum suction to adsorb the softened packaging material onto the surface of the product, and tightly adhere it to the product through a rolling device. Finally, the packaging material is cooled and solidified through a cooling device to complete the packaging process.

2.Vacuum System: The vacuum system of the vacuum packaging machine is mainly composed of vacuum pumps, vacuum valves, vacuum pipelines, etc. When starting the vacuum system, the vacuum pump extracts air from the working chamber through the vacuum valve, creating a vacuum state inside the working chamber. At this point, the packaging material is adsorbed onto the surface of the product under the action of vacuum suction, thereby achieving a tight packaging effect.

3. Heating device: The heating device of vacuum packaging machines usually uses electric heating tubes for heating. Electric heating tube is a method of heating packaging materials to a softened state by generating heat through a resistance wire through an electric current

Application of Rolling Vacuum Packaging Machine:

1. Food industry: such as cooked food, pastries, meat, fruits, etc. By rolling vacuum packaging, the shelf life of food can be effectively extended, preventing contamination and spoilage during transportation and storage.

2. Pharmaceutical industry: In the pharmaceutical industry, vacuum packaging machines are mainly used for packaging medical devices, drugs, etc.

3. Electronics industry: In the electronics industry, vacuum packaging machines are mainly used to package electronic products such as casings and circuit boards.
