Jiangsu Laiyi designs and manufactures extrusion laminating/coating
lines on the strength of a thorough expertise in the co-extrusion of special
polymers - customized and modular layout to meet the demand for special
products; - chill-roll unit with precise temperature control - rapid cooling
system - special winders and unwinders suitable for any final application.
Jiangsu Laiyi extrusion and co-extrusion units at the forefront of technology,
boasting a high manufacturing quality with components suitable for processing
also corrosive polymers. we has focused on high performance extruders with
special screw design for a wide range of materials like LDPE, SURLYN, EVA, EAA,
PP, with customized solutions including different layers, sizes and die widths.
一,Release Paper Extrusion Laminating Machine
- Release paper is widely used to release papers and photo papers, etc.
- Can be single side and double side laminating.
- We also make customized machine.
- The line can be nomal or high-speed line.
- This is a double station tumble initiative automatic unwinding and rewinding line.
二,Specification of the Line:
|Effective laminating width:
|Max unwinder diameter:
|Max rewinder diameter:
||300kg/h,400kg/h or 550kg/h
|Laminating thickness range:
|Water supplier temperature:
||380V-50Hz (3-phase 5-wire)
- Two original paper rolls can be installed at the same time on the shaftless unwinder.
- Auto-splicing is controlled by computer and can be done without stopping the line.
- Web-guide device ensures that the paper/paper board passes uniformly and neatly.
- Bead cutter for edge trimming.
- Corona treatment on the surface of paper is to increase the peeling strength of PE and paper.
- Rewinder consists of rewinding stand, tension control system, splicing device and towing device.
- Tension control system is to ensure the constant tension of rewinding.
Bead cut equipment
- Shrink-width makes two sides thicker, as a result, the two sides of the composite material need to be trimmed, otherwise the composite material will have some quality problems such as drape, crimp and unevenness.
- It is convenient to renew cutter and adjust effective width. It can save time and labor at the same time, and makes the products flat and smooth.
The pre-treat unit
- The pre-treatment includes corona treatment and static elimination on the surface of base materials. Especially in extrusion coating process, corona treatment is needed to assist molten web to permeate into the pores or cottony gaps on the surface of base materials under the pressure of pressure roll, improving the adhension between coating film and base materials.
- Corona treatment will stop when production line speed below 20m/min and automatically starts when speed above 20m/min.
- The corona machine is equipped with work condition indicating lamp, oil-immersed high-frequency transformer, electric digital meter reading output power and adjustable low-speed interlock. It will be warning on overheat,hyper-charger, breakdown and corona lost, and works with high-efficiency and low-consumption.
