Product Details product description
PU sandwich panel production line is used for continuous production of sandwich panels, double side is flexible material with polyurethane or Phenolic inside . The main products of this line are exterior wall insulation composite panel and duct of central air-conditioner. It’s working principle is : four component of regid foaming material according to a certain ratio deliveried to mixing head by metering pump of high pressure foaming machine, and distributed even on the bottom sheet of lower sandwich panel, deliveried with upper coil to the double belt laminating conveyor at the same time. Regid foam blowed and solidified to shape during the upper and lower conveying chain plate. The shapped sandwich panel cut to a certain prodution desired length products by cutting machine on produciton line.

Ø Heating system 1 set
III. Technical Specifications Description
 
Main Layer Press Machine
 
1. Portal Frame
 
It is the main loading part of the sandwich panel foaming sprayer, the machine frame is welded with superior structural steel which meets the design requirements.
 
2. Backboard (supporting plate)
 
Made of steel beams welded, whose function is to bear the upper mould and bottom mould, which can be lowered or lifted by the hydraulic system. It is processed as a whole which offers high stability and flatness.
 
3. Bottom Base
 
It is welded with superior structural steel firmly and solidly.
 
Backing Board Conveyor Rolls
 
The rails for backboard going in or out are installed with necessary room, water-pipes, electricity lines, and so forth.
The rails are separated, and when the mould is locked part of the rails are lifted while the remaining part of the rails is kept still.
 
4. Synchronous Mechanism Organ
 
In order to avoid non-synchronous operation, especially in the length while the hydraulic cylinders work, the organ guarantees the cylinders to work synchronously. The layer press machine has a mechanism to make the gears, gear racks synchronous to avoid damage of the cylinders
 
5. Fixed Backboards
 
The backboards which are welded with fine art processed hard steel, reach the grade and rigidity requirements needed during the polymerization phase (foaming).
 
The working surface after mechanical processing, of which the high-precision leveling is one of the most important conditions, guarantee the PU sandwich panel quality.
 
The cycle-heated pipe is arranged inside the backboards.
 
6. Mobile Backboards
 
As main part of the layer press machine, there are 4 pieces of bilateral side mobile backboards, which can move freely in or out.
 
The art design guarantees the arrangement of the heater cycle hose as in the upper backboard.
 
Mobile Backboards IN-OUT Drive System
 
The mobile backboards are motor driven, and it can move freely in or out according to design.
 
7. Hydraulic System
 
For the hydraulic system, a low-pressure drive and high pressure protection is adopted to realize the die-locking action, and to save space and energy.
 
The pressure compensation is automatically accomplished by the switches, and sets the safety and protection system. The oil tank is placed on the ground, and all the valves are installed on the tank as a whole, being easy to installed and maintain.
 
The returning oil pressure is 0.2-0.3 MPa, the oil temperature and accumulation is monitored by instruments.
 
8. Heating System
 
The 5 backboards, installed on the layer press machine, have water hoses cycle routine, which is heated by water as its heating medium, which heat the backboards to guarantee the temperature needed for curing the sandwich panels during the polymerization phase.
 
Mould Heating Machine
 
The adopted water heating system, of 50 Kw power, can supply enough hot water according to the requirements.
Heating Hoses
 
Rubber hoses connect with the mould heating and backboard, and to protect the external wall to make the backboards move in-out freely.
 
9. Electrical Control
 
Consists of hydraulic button controls, time-control buttons, as well as protection buttons, which show the working status and there is an inter-lock and auto-lock function.
 
The curing time for a sandwich panel can be adjusted within 0-30 min according to the polymerization requirements.
 
10. Mould Frames
 
It can produce PU sandwich panels within 1250 mm x 6000 mm x 200mm.
