Shrinking machine process:
1, first set the heating time for the machine
2. After pressing the manual or automatic button, the electromagnetic output of the rack cylinder solenoid pushes the gear, and the gear drives the chain. At this time, the rear position of the rack cylinder is disconnected. When the rack cylinder runs to the top dead center, the front position of the rack cylinder is close to the switch, and the oven cylinder solenoid valve is electrically output.
3. When the oven cylinder runs to the top dead center, the timer starts to delay and the rack cylinder solenoid valve is de-energized.
4. At the end of the time, the oven cylinder solenoid valve is de-energized.
5. Decide whether to proceed to the next workflow according to the working mode flag.
The heat shrink packaging machine is one of the more advanced packaging methods in the market. It is wrapped around the product or package by shrink film. After heating, the shrink film is wrapped around the product or package to fully display the appearance of the product and improve the product's marketing performance. Aesthetic and value. At the same time, the packaged articles can be sealed, moisture-proof, anti-pollution, and protect the goods from external impact, and have certain cushioning properties, especially when packaging fragile products, which can prevent the containers from being scattered when scattered. In addition, the product back can be reduced. The possibility of dismantling and stealing.
Shrinking machine packaging
According to different packaging methods, the shrinking machine is roughly divided into the following three packaging forms:
1. Open ends
　　 It uses a tubular film or a flat film to wrap the packaged product in a sleeve and then heat shrinks. After the package is completed, there is a shrinkage port at both ends of the package.
(1) When a tubular film is used, the opening of the film is first opened, and then the product is pushed into the film by means of the chute, and then the film is cut. As shown in Figure 1. This method is more suitable for wrapping cylindrical objects, such as batteries, paper rolls, and cans. The advantage of the tubular film packaging is that the sealing process is reduced by 1 to 2, and the appearance is beautiful. The disadvantage is that it cannot meet the diversification requirements of the product, and is only suitable for mass production of a single product.
(2) Wrap the article with a flat film, which can be wrapped in a single flat film and a double flat film wrap. The film should be wider than the article, and the double film should be wrapped with the upper and lower film. When the previous package is sealed, the two films are sealed and the product is machined or hand-made. Pushing the film upright, the sealing mechanism is dropped after the position is closed, and the other side of the product is sealed and cut. After the film wrapped product is heat-shrinked, the two ends of the package are contracted to form an oval opening, and a single flat film is used. When the flat film is unfolded, the wrapped product is fed into the middle of the flat film to form a horseshoe-shaped wrap, and then heat-sealed and lapped.
2. Four-sided sealed
　　 The product is wrapped around a flat film or a tubular film, and the joint is sealed by a lap joint. Used for product packaging that requires sealing.
(1) Use the L-type sealing method for the folding film, fold the film with the reel, pull the film out to a certain length and place it in a horizontal position, and open the open end by mechanical or manual to push the product to the crease.
(2) Pillow bag packaging can be used with a single flat film. In this method, a single flat film is used, and the longitudinal slit is firstly formed into a cylindrical shape, and the product is pushed into the product, and then the horizontal slit is cut into a pillow type package or the both ends are punched and tied into a tubular package.
(3) The double flat film four-side sealed package is similar to the open type at both ends, and only needs to be equipped with a two-side sealing device on the machine.
(4) When wrapped in a tubular film, it is only necessary to perform sealing and puncture while the tubular film is cut, and then heat shrink. There is often a needle at the side of the sealer. When the heat seals, the needle pierces the vent hole on the film, and the hole is often closed by itself after heat shrinkage.
3. One end open
Tray shrink packaging is a typical example. The film is first made into a square bottom bag, and then the big bag is placed on the stacked product tray from top to bottom, and then heat-shrinked. Place the tray with the product on the conveyor belt and put on the shrink film bag; the conveyor belt is fed into the heat shrinkable passage, and the shrinkage package is completed after the heat shrinkage passage. Its main feature is that the products can be firmly bundled in a certain number of units, which will not be loose during transportation and can be stacked in the open air.
What are the differences and connections between shrinking machines and vacuum packaging machines ?
(1) Shrinking machine is suitable for packaging of glass bottles, styrofoam, cartons, toys, electronics, electrical appliances, stationery, books, records, hardware tools, daily necessities, medicines, cosmetics, beverages, fruits, commemorative labels, etc.
(2) Vacuum packaging machine including food vacuum packaging machine is composed of vacuum system, pumping air sealing system, hot pressing sealing system and electrical control system. The vacuum packaging machine automatically seals the inside of the bag after it is vacuumed. Because of the high vacuum in the bag, the residual air is very small, inhibiting the proliferation of bacteria and other microorganisms, and avoiding oxidation, mildew and spoilage of the article. Some soft items can be packed in a fully automatic vacuum packaging machine to reduce the packaging volume for transportation and storage.
