How to operate the heat shrinking machine

heat shrinkable film packaging machine is also called heat shrinkable packaging machine. PU film shrinking machine can shrink many products. Many daily necessities and electronic products I use are shrunk by PU film shrinking machine, but how many people know the principle and operation process of shrinking machine?, Purpose of shrinking machine

I. working principle

shrink the shrink film wrapped outside the product or package. After heating, the shrink film shrinks and wraps the product or package tightly, which fully shows the appearance of

items, improves the merchantability of items, and increases the beauty and sense of value! The goods packed by the heat shrinking machine can be sealed, moisture-proof, pollution-proof, and protect the goods from external impact. It has a certain buffer, especially when packaging fragile goods, it can prevent the containers from flying away when they are broken. In addition, it can reduce the possibility of products being disassembled and stolen

II. Operation flow and

1 Place the machine on a flat and clean ground without corrosive gas. Before starting the machine, check whether the parts of the machine are loose and displaced during transportation, and adjust them in time if found. (for your personal safety, please ground the machine before use and ensure good contact.)

2.346 the release amount of ammonia in concrete admixture is powered on and started up. If only sealing and cutting is carried out, please turn the change-over switch to the corresponding position

3. Before shrinking operation, preheat the machine for 5-7 minutes to reach the required working temperature indicated by the thermostat (the working temperature is generally set between 170 ℃ ~ 230 ℃, which can actively help customers improve the continuity of products. When using PVC shrink film, it is generally not more than 200 ℃), and the sealing and cutting time should be controlled at about 1 second, which can not only ensure the sealing and cutting quality, but also prolong the service life of the blade. The contraction time can be set at 5 ~ 6 seconds at the beginning. After 30 minutes of operation, the temperature in the chamber will rise with the extension of time, which can be reduced to 3 ~ 5 seconds, or the contraction time can be adjusted according to the actual situation

4. Press the handle of the upper cover. When the transparent working cover is pressed in place, the electromagnet will be powered on and closed immediately to start sealing, cutting and shrinking. At this time, the operator's hand can leave without pressing the upper cover all the time. Observe the shrinkage process. After the shrinkage is completed, the electromagnet is powered off, and the parameters of strength, maximum force and elongation at break should be selected. The open cover pops up automatically. After the whole operation process is completed, take out the finished product. Then the next packaging work can be carried out

using heat shrinkable packaging machine is one of the more advanced packaging methods in the market. In addition to its own advantages, it can also reduce the possibility of products being dismantled and stolen; It is applicable to many pieces of products, and our customers have also successively resumed the tight packaging and pallet packaging of products. Heat shrinkable machines are widely used in the packaging of glass bottles, styrofoam, cartons, toys, electronics, electrical appliances, stationery, books, records, hardware tools, daily necessities, cosmetics, beverages, fruits, commemorative labels and other items
