High-speed extrusion coating compound production line (liquid aseptic packaging)


This production line is a high-speed extrusion compounding line for liquid milk and beverage carton special materials. It is suitable for coating grade coating resin such as LDPE, LLDPE, PP, EVA, EAA, EMAA, etc. It is used in the production of paper-plastic aluminum composite multi-layer packaging materials ( Liquid sterile packaging material).

Production line characteristics
1. The production line mainly consists of extrusion, composite (positive / reverse), double-station hydraulic shaftless unwinding, paper machine, rectification, auxiliary unwinding, cooling traction, corona, trimming and edge processing, online testing Thick, static elimination, winding, changing, unloading, electronic control system and other components.

2. The structure design of the whole machine is firm and firm, and the appearance is generous; at the same time, the introduction of foreign advanced technology ensures stable production with high productivity and high line speed and has high quality product appearance and performance.

3. The extrusion screw has a large aspect ratio design structure, equipped with a cast iron air-cooled heater, a hydraulic quick-change device; the introduction of the Italian labyrinth static mixer; the T-die uses a high-precision imported original brand.

4. The cooling roller adopts a large-diameter special flow passage cooling structure to ensure good cooling effect and uniform roll surface temperature in high-speed production;

5. After setting the temperature, only use the lifting speed, automatically calculate according to the setting parameters, the speed changes, the thickness of the coating is constant, and it can also be operated independently.

6. Fully automatic constant tension control, independent hydraulic shaft clamping arm type double station unwinding, no need for air expansion shaft, hydraulic feeding, save the user input mechanism, automatic A/B axis automatic winding, connecting materials Short waste on the short substrate. The extruder can be equipped with single extrusion, double extrusion and multi-layer coextrusion according to customer requirements.

7. The whole machine adopts PLC control and human-machine interface touch screen operation, which can set parameters arbitrarily, and has functions such as automatic calculation, memory, detection and alarm. Support network remote detection, which provides more comprehensive maintenance for the system.
8. The electrical control components are all well-known brands at home and abroad, and the production line runs smoothly and reliably, which better guarantees the quality of the equipment.

Features
1. Higher toughness, leakage prevention, and barrier properties.
2. Green, beautiful, economical, and recyclable.

Main use of the product
The paper plastic aluminum liquid aseptic package is used in the liquid food filling field such as milk, juice, tea and coffee.
