According to the film, it can be divided into PE film shrinking machine and POF film shrinking machine;
According to the practical scope, it can be divided into disinfection tableware heat shrinking machine, heat preservation board/cement foaming board heat shrink packaging machine, beverage heat shrink packaging machine, tableware heat shrink packaging machine.
Disinfecting tableware heat shrinking machine
1. It adopts quartz far-infrared tube heating mode, which can continuously generate infrared radiation during work. With strong wind circulation, the temperature of the heating chamber becomes more uniform and energy is saved.
2. The transmission part adopts high-power DC motor, which is characterized by stepless speed regulation and high bearing capacity. It can work continuously for a long time, and the operation is stable and reliable.
3, using a special mechanical structure design, the shape is more beautiful, luxurious, and make maintenance easier and convenient.
Suitable temperature for shrink film:
POF for light industry, food, noodles, biscuits, beverages, tableware, hotel supplies, stationery, arts and crafts, hardware tools, daily necessities, chemical products, toys, photo frames, medicine boxes, medicine bottles, cartons, etc. , PVC film heat shrink packaging.
The cuff-type laminating machine is suitable for the bottomless tray or bottom-loaded heat shrinkable packaging of various bottles such as cans, mineral water, beer, glass bottles, beverages, etc. At the same time, it is used together with the constant temperature PE shrinking machine to achieve the perfect packaging effect. ;
Beverage heat shrink packaging machine:
The heat shrinkable film packaging machine is a more advanced packaging method on the international market. It is wrapped on the outside of the product or package by a shrink film, and then heated to shrink the packaging material to wrap the product or the package, fully displaying the exhibitability of the article to increase the appearance and value;
At the same time, the packaged articles can be sealed, moisture-proof and pollution-proof. And to protect the article from external impact, has a certain cushioning property, in addition, can reduce the possibility of the product being dismantled and stolen; when the shrink film shrinks, a certain pulling force is generated, so that a group of articles to be packaged can be wrapped. It plays the role of strapping, especially suitable for the collection of multiple sets of items and tray packaging, so this product can be widely used in the packaging of various small products.
Heat Shrink Machine Repair:
The continuous heat shrink packaging machine is heated by quartz far-infrared tube, and the shrinking temperature and conveying speed are stable and adjustable. The products after packaging can be sealed, moisture-proof and anti-collision, and are suitable for multi-piece wrapping and tray packaging. The conveying part has two kinds of mesh belts and rod chains.
1. The shrinking machine should be used in an environment where the temperature is -10 °C - 50 °C, the relative humidity is not more than 85%, there is no corrosive gas in the surrounding air, no dust, no explosion hazard.
2. For the shrinking machine to ensure the normal operation of the vacuum pump, the vacuum pump motor is not allowed to reverse. The oil level should be checked frequently. The normal oil level is 1/2-3/4 of the oil window (cannot be exceeded). When there is moisture or oil color in the vacuum pump. When it turns black, it should be replaced with new oil (usually one or two months of continuous work, 1# vacuum gasoline or 30# gasoline, oil can also be used).
3. Impurity filter should be frequently removed and washed (usually once every 1-2 months, such as packaging debris should shorten the cleaning time).
4. For 2-3 months of continuous operation, the rear cover 30 should be opened to add lubrication to the sliding parts and the switch bumps. The connection activities on the heating rods should be lubricated according to the usage.
5. For the decompression, filtration, oil mist triplet 24 should be checked frequently to ensure oil mist, oil in the oil cup (sewing machine oil), no water in the filter cup.
6. The heating strip and the silicone strip should be kept clean and free from foreign matter, so as not to affect the quality of the seal.
7. On the heating rod, the two-layer adhesive under the heating sheet acts as insulation, and should be replaced in time when there is damage, so as to avoid short circuit.
8. The user has self-prepared working gas source and inflatable gas source. The working pressure of the shrinking machine has been set to 0.3MPa, which is more suitable. Do not adjust too large without special circumstances.
9. Shrinking machine Do not allow tilting and impact during handling, and can not be carried over.
10. There must be a reliable grounding device during installation.
11. It is strictly forbidden to put your hand under the heating rod to prevent injury and immediately cut off the power in case of emergency.
12. When working, first ventilate and then energize. When the machine is shut down, first cut off the electricity and then cut off the gas.
