One of the more advanced packaging methods—heat shrink wrap
Automatic heat shrink wrap packaging machines, also known as shrink wrap machines, are widely used in the packaging of glass bottles, styrofoam, cartons, toys, electronics, electrical appliances, stationery, books, records, hardware tools, daily necessities, medicines, cosmetics, beverages, fruits, commemorative labels, and other items.
The shrink wrap packaging machines in our factory have many models and complete functions, which can meet the packaging needs of different customers for different products.
Automatic Sleeve Sealer
- Adopt “Siemens” “PLC” program controller to realize the integration of machine, electricity, and gas.
- Using worm gear reducer, product feeding, and film feeding smoothly without jitter.
- Specially designed sealing knife, the sealing line is firm, not cracked, and not easy to stick to the knife.
- The frequency converter controls the transmission speed.
- Adopts an imported dual-transport fan motor, so that the hot air in the furnace cavity is evenly distributed, and the shrinking effect is more beautiful. Ultra-large air volume cooling system, the product is quickly cooled and shaped after heat shrinking.
- The solid steel rod is used to cover the imported silicone tube, and the chain rod type conveying is durable. The feeding conveyor belt can be designed as left feeding or right feeding according to the needs of the site.
- When packaging color film, it is necessary to add a color mark positioning system to accurately locate it.
Automatic L bar sealers
- The sealing knife is made of a Teflon-coated anti-stick and high-temperature resistant alloyed knife, the sealing will not crack, will not coke, will not emit smoke, and zero pollution.
- According to different products, it is equipped with photo-eye detection, with one set for horizontal or vertical detection, which is convenient for switching and selection.
- Automatic feeding, the length can also be adjusted automatically by the combination of the electric eye and the timer. Equipped with an induction motor to automatically handle the waste.
- Using the original “OMRON” digital temperature controller with a built-in PID function, the temperature of the sealing knife is extremely sensitive and accurate and can be set at will. The sealing knife itself also has an automatic protection function, which can effectively prevent miscut packaging, and has an automatic alarm function, which greatly improves the safety of the operator.
- The whole set of machines truly realizes the unmanned operation connected with the production line, and the specially designed upper and lower synchronization mechanism of the film can correct the deviation of the film.
- It also has a close connection function, which is specially designed for small products. When the size of the package is changed, the adjustment is very simple, and there is no need to change the mold and bag maker.
Automatic Side Sealer
- The horizontal knife in the sealing part adopts a vertical drive, and the vertical knife adopts a constant temperature side sealer. The sealing line is straight and firm to achieve a beautiful sealing effect.
- The constant temperature heating sealing and the cutting system can be used to seal and cut various industrial standard shrink films such as POF. Products with different packaging specifications and sizes can be completed only by adjusting the hand wheel, which increases reliability and is easier to operate.
- The vertical knife can do the sealing and cutting action sustainably, and the product length is not limited.
- The machine adopts a PLC controller, and the sealing and cutting system can continuously and smoothly perform sealing action without replacement, and the maintenance operation is very simple.
- Feeding length control by the combination of electric eye detection and timer, the length of the film is precisely controlled, making the shrinkage effect easier to control.
- A total of two sets of horizontal and vertical sensors are installed, which is convenient for switching and selection. For thin or small packages, the sealing and packaging operation can be easily completed.
- The automatic handle of the waste material, controlled by a separate motor, will not be too loose or too tight and crack, and the waste is easy to disassemble.
- An automatic air-blowing function can be added according to customer needs.
- The front-end power feeding line and rear-end unpowered storage platform can be selected as required.
In short, the heat shrink wrap packing machine is one of the more advanced packaging methods in the international market. It uses shrink film to wrap the product or package outside, and then heat it to shrink the packaging material and wrap the product or package tightly, fully showing the display of goods, in order to increase the sense of beauty and value; At the same time, the packaged goods can be sealed, moisture-proof, anti-pollution. And protect goods from external impact, with a certain buffer, in addition, can reduce the possibility of products being removed, or stolen; when the shrink film shrinks, a certain tensile force is generated, so a group of items to be packaged can be tightly wrapped, It plays the role of bundling the rope and is especially suitable for the collection and tray packaging of multiple groups of items, so this product can be widely used in the packaging of various small products.
