Panel Automatically Cutting System
1. Cutting machine can move 2500mm longitudinally along product line;fly saw of the cutting machine can move transversely 1900mm, Cutting machine moves longitudinally and transversely along the slide way.
2. Cutting machine adopts one-side blade band saw manner, cutting and revolving after cutting. The cutting saw can revolve, so cutting in two directions is realizable.
3. There is panel tight-pressing system (pneumatic) in the cutting machine.
4. There is location limiter to limit longitudinal and transverse motion of cutting machine.
Production Characteristic and Use
This machine is suitable to PU sandwich production, such as wall panel and roofing panel.
The plate can insulate heat, sound, and prevent burn, widely used in roof panel, wall panel, and so on.
PU Wall Panel
Working flow
Loading material---decoiling---guide--roll forming---feeding roller ---pre-heat the steel---foaming---combined two parts---shearing---packing manually
PU Sandwich Panel Production Line
First stap:
Loading material---decoiling---guide--roll forming---cut to length---out table
Second step:
Loading roofing product---pre-heat the steel---foaming---combined two parts---transportation---packing manually
Three Sets of Roll Forming Machine
1. Function: Roll forming for the profiles of PU panel
2. Use the welding H-beam, motor driver, sprocket chain driving
3. Technical data: Material of roller NO.45forged steel, with digital controlled procession,plated with hard chrome on surface of forming rollers
PU Sandwich Foaming Line
1.Two sets of conveyor rack: up conveyor is about 24m, down conveyor is about 30m.They lead the steel sheet from the roll forming machine to preheating room and to foaming,to cutting.
2. One preheating room: It is built by heat-insulation material, and it could heat up the steel sheet to 25-38 by heater.
3. One set of PU two component Liquid mixing and injecting section for foaming : it adopt Chinese high pressure pump. It have the temperature control system and material-level monitoring system. The tank of the material is about 150L. Two tanks.
4. Foaming and double rubber device include motor driver system to make panel.
5. The width of belt board is 1250mm, the range of adjusting distance between upper and lower frame belt board: min 25mm, max 200mm. And the range of adjusting thickness of sandwich panel :30mm,50mm,100mm.(30-50 for celling , 50-100 for wall)
Introduction of Machine
- This PU Sandwich panel production line is an automatic production line.
- In the PU sandwich panel producing procedure, the product line can continuously produce sandwich panel with PU as its core material.
- The liquid state raw materials were continuously injected into the middle of three formed panels and reacting,foaming,solidifying in the double-rubber .
- The PU sandwich panel could be cut out automatically according to the required length for users.
