Polyurethane Sandwich Panel Production Line For Color Steel With PLC Touch Screen Control

   Description of PU Sandwich Panel Line   

• Machine is to make the sandwich panel with the color steel sheet or galvanized sheet and the core of polyurethane

• The multi-layered laminator is consisted of the press and the rail stands. Two worktables move into the press and the other two stay on rail stands. Initially, put the top and the bottom sheets inside of mould frames and then seal, after that, feed the worktables into the press. When worktables inside the press moves out orderly, the other two feed in at the same time. Upon the finish of feeding, the press will close and slant at a angle, waiting for injecting PU raw materials from the PU mixing head into different panels. Meanwhile materials start foaming and curing. At this time, mould frames on worktables moved out for taking out the finished products.

   Main Technical Specifications   

1. (a) Thickness : roof steel panel 30-200mm and wall steel panel 30-200mm.

(b) PU foam density : 40±5 kg/m³

(c) Panel width : 50-1150mm

(d) Thickness of galvanizes color steel coil : 0.4mm~0.7mm

2. The production speed is different according to the panel thickness.

Recommended speed is 6M/min for 50mm thickness, 4M/min for 75mm thickness.

3. Speed of forming machine is 0~12m/min and adjustable. The length and amount of production can be set and count automatically by control panel.

4. Hydraulic material discharge stand can feed steel sheets automatically and keep accuracy during long time operation.

5. Caterpillar conveyor contains upper/lower construction and double-sided block belt. The effective thickness can be up to 200mm so it can provide a large variety of roof and wall products easily by changing the spec of the side blocks.

6. Bend saw cutter : Maximum thickness is 200mm. The suction channel is reserved for additional suction system to prevent the dust pollution.

7. The characteristic of this continuous rubber belt sandwich line is ALL parts including forming machine, lamination, conveyor, cutter and auto stacking equipment are synchronized by a central Ratio Setter control system. The user can easily control the speed through the main speed controller (VR).
