How to operate heat shrink machine?

Shrink film packaging machine, also known as heat shrink packaging machine, film shrinking machine can shrink a lot of products, many of my daily necessities and electronic products are shrinked by the film shrinking machine, but how many people know the principle of shrinking machine And the operation process? The use of shrinking machine?

First, the working principle of the use of shrink film wrapped in the outside of the product or package, after heating, the shrink film shrinks tightly wrapped products or packages, fully displayed

The appearance of the articles improves the display and sales of the articles and increases the beauty and value! After being wrapped by a heat shrinkable machine, the packaged articles can be sealed, moisture-proof, and anti-pollution, and the goods can be protected from external shocks and have a certain cushioning property, especially when the fragile goods are packaged, which can prevent the containers from scattering when broken. In addition, the possibility of product being dismantled or stolen can be reduced.

Second, the operation flow and

1. Place the machine on a clean, level surface with no corrosive gas. Before turning on the machine, check whether the parts of the machine are loose or displaced during transportation. If any of them are found, adjust them in time. (For your personal safety, ground the machine before use and make sure it is in good contact.)

2. Turn on the power and turn on the power. If only the seal is cut, please switch the switch to the corresponding position.

3. Before shrinking operation, preheat the machine for 5-7 minutes, which is the required working temperature indicated by the thermostat (the working temperature is generally set between 170°C and 230°C. When using PVC shrink film, generally do not exceed 200 °C), seal cutting time should be controlled in about 1 second, so that it can not only ensure the quality of sealing, but also extend the service life of the blade. The contraction time can be set at 5 to 6 seconds. After 30 minutes of operation, the temperature in the chamber increases with time. It can be reduced to 3 to 5 seconds, or the contraction time can be adjusted according to actual conditions.

4. Press the top cover handle. When the transparent cover is pressed down, the electromagnet will instantly energize and start to seal and contract. At this time, the operator's hand can leave without pressing the top cover all the time. Observe the contraction process. After the contraction is completed, the electromagnet is de-energized and the transparent cover springs up. The entire operation process is completed and the finished product is taken out. You can do the next packing job.

The use of heat shrink packaging machines is one of the more advanced packaging methods in the market. In addition to including its own advantages, in addition can reduce the possibility of the product being dismantled and stolen; applicable to tight packaging and pallet packaging of multiple items. Heat shrink machines are widely used in glass bottles, styrofoam, paper boxes, toys, electronics, electrical appliances, stationery, books, records, hardware tools, daily necessities, cosmetics, beverages, fruits, commemorative labels and other items.
