Heat shrinkable film packaging machine
1, set the heating time
2. After pressing the manual automatic button, the electromagnetic output of the rack cylinder solenoid valve 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 powered off.

5. Decide whether to proceed to the next workflow according to the working mode flag.

Packaging method of heat shrinkable film packaging machine
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.

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.

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 commodity 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.
