PET sheet twin screw production line (crystallization-free drying)

The crystallization-free and drying-free exhaust-type PET sheet unit launched by Nanjing Henglande has the advantages of low energy consumption and high efficiency. It has made major technical upgrades to the core vacuum system, from the original Roots-water ring pump unit to a Roots-rotary vane pump unit, which can achieve a vertical vacuum of 10Pa. At the same time, it uses a PET-specific alloy steel thin-walled roller group to greatly improve the cooling efficiency, thereby increasing production and improving the toughness and transparency of the product.

Plastic PET Sheet Production Line Features:
The screw adopts special mixing function and high-speed capability design to ensure that the plastic melts, the color is uniform and the extrusion volume is increased. The hanger-type die head adopts a special double throttling design to make the thickness adjustment of the plate more accurate. Temperature control ±1℃ can accurately control the plasticization process and the thickness and flatness of the plate. The three-roller water press adopts horizontal vertical or 45° tilting type, and can be freely raised and lowered to provide more options in the operation of thick and thin plates and improve the quality of the plate. The thickness control of the plate adopts screw adjustment and hydraulic pressure wheel two-way adjustment to accurately control the thickness of the plate. The independently controlled roller temperature control system can accurately control the temperature of the pressure roller to make the thickness of the plate uniform. The length and quantity of the slicer plate are accurate. The winding table device adopts a high-level torque motor, which can adjust the speed and winding tension at will to achieve the purpose of flat winding of thin plates. With the slitting device, the required product width can be freely set. The machine is equipped with an automatic meter to set the product length.
Plastic PET sheet production lines are widely used in various packaging industries such as medicine, food and electrical appliances, toys, and printing industries.

Adopt multiple extruders co-extrusion technology. Produce multi-layer co-extruded composite PET sheets such as: APET/PETG, PETG/APET/PETG, APET/RPET/APET and other multi-layer composites. Widely used in blister thermoforming, printing, hardware bags, gift folding packages, etc.
☆ Equipped with precision distributor, uniform layering, adjustable ratio of each layer. Digital display.
☆ Oblique horizontal tableting structure, more convenient operation and maintenance. Roller independent transmission. Line speed and extruder speed synchronous closed-loop control, full servo system.
☆ The whole machine adopts Siemens PLC control to realize the automatic control operation procedure and control system of parameter setting, data calculation and feedback, alarm and other functions
