Heat shrink film wrapping machine

1. Operating steps
a) Bottle infeed – Consists of conveyor belts and guide plates to arrange the products in rows.
b) Grouping – Divides the products into a certain number of combinations, equipped with an in-line conveyor grouping device.
c) Wrapping – Unwinds, cuts, and wraps the film onto the products.
d) Heat shrinking – Passes through a hot air tunnel to form heat-shrink wrapped products. Heating time: 6–10 seconds.
e) Cooling and setting – Uses fans for cooling and natural cooling.

2. Uses a modular unit combination structure, suitable for wrapping heat-shrink products of different specifications.

3. Patented film unwinding and cutting device technology, allowing simple and precise adjustment of film length.

4. Equipped with dedicated servo motors for film feeding and cutting.

5. Dual roll film shaft configuration, with alternate film roll change function. Film roll change time: <3 min.

6. When the plastic shrink film runs out, the machine will automatically stop and alarm.

7. The plastic film does not melt and bond on the appearance; it is only overlapped at the bottom of the packaged products.

8. Replacing the shrink film cutter and cleaning the cutter is simple and convenient.

9. Transparent sliding glass doors provide a wide, clear view of the machine's operation. When opened, the cutting device can be controlled and cleaned, reducing downtime for maintenance.

10. Requires very few operators during production packaging.

11. Equipped with digital displays or mechanical counters for easier operation.

12. Hot air design with variable flow tunnel structure
a) The variable flow device inside the tunnel ensures that hot air is evenly blown not only within the chamber but also to the lower part of the conveyor chain mesh, ensuring good shrinkage of the film bottom overlap, making the shrink-wrapped products tighter and more aesthetically pleasing.
b) Dual-chamber heating tunnel for uniform shrinkage.
c) Heating elements are easy and quick to replace.
d) Rapid cooling fan devices are installed outside the heating tunnel.

13. In the event of a sudden power outage during production, a manual conveyor belt turning device is provided to move products out of the heating tunnel.

14. Advanced PLC control system.

15. Fully automatic PLC control with a dedicated LCD operation interface, displaying instant and cumulative packaging quantities. Cumulative data can be printed out via a printer.

16. Setting programs can be changed conveniently and quickly.

17. The control panel uses an electronic touch screen and buttons for operation, allowing direct input and modification of packaging parameters, and can also store parameters for multiple different packaging specifications.

18. Full monitoring of machine operation; all packaging steps are detected by sensors with automatic diagnostic functions. When an error signal occurs, the machine automatically stops, an alarm light flashes, and the error code type appears on the display screen.

19. Equipped with switching logic interlocking with external devices.

20. All electrical and pneumatic control systems comply with international standards (CE standard).

21. Complete electrical and piping systems that can be directly connected to the user's utilities.

22. The heat shrink tunnel temperature is equipped with automatic adjustment, display, and fault alarm.

23. The main machine uses a servo drive system.

24. Mechanical parts are made of stainless steel, chrome-plated zinc steel, and corrosion-resistant aluminum alloy materials, with excellent surface coating quality and strong anti-rust performance.

25. Safety guard: Fully enclosed, consisting of a colored frame with plexiglass panels, and glass doors with automatic safety lock switches.

26. The side panels of the infeed conveyor frame are made of stainless steel.

27. Equipped with complete safety devices, meeting safety standards.
