Rock Wool/Glass Wool/PU Sandwich Panel Production Line
With Double-Belt Conveyor
Introduction of machine
- A combination production line,wich can produce PU,rock wool,glass wool sandwich panels,with the function of edge foaming and sealing for rockwool,glass wool panels.
- High pressure glue spraying unit:glue is sprayed on up and down steels sheet directly,wich saves glue and insures quality by maximing the stickness of glue.
- Rotary type:block type,two turning.It is the most advanced and reliable technology,suitable for producing low density glass wool panels.

Primary technology parameters of PU sandwich panel product line
- Production Material(mm):(0.25-1.0)×L, yield strength≤G300 Colored steel
- Production speed:4-8 M/min
- Production type: totally continuous production with PLC controlling
- PU foam thickness: 25-100mm
- Composite structure:position fixed by double rubber tracker
- Foaming system: totally automatically continuous foaming, quantity of foaming could be stepless adjustable
- Power of production ≥ 22KW
- Total power ≥ 35 KW
- Cutting:pneumatic piston driving, non-stop cutting via sliding table
- Electronic controlling system: full-frequency PLC controlling system
Uncoiler roll forming machine
- Excellent groove design and forming technics of roll forming machine combine with aided design of German copre software which can release whole stress and reduce waves while roll forming and keep the final products with planeness.
- Two-side projecting shaft roll former,rollers can be fixed on two sides shafts.
- Fast vertical loading of roll forming stations
- Roll forming machine on two side can be bidirectional changed,matched with double-belt conveyor to keep center.
- Width adjusting device by using high-precision ball screw and linear guide,accuracy tolerance+/-0.5mm.
- Pre-heating room is made of 50mm PU Sandwich panel as fence,which decreases heat-loss substantially.
PU Sandwich foaming line
- 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.
- One preheating room: It is built by heat-insulation material, and it could heat up the steel sheet to 25-38 by heater.
- 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.
- Foaming and double rubber device include motor driver system to make panel.
- 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)
- The double belt adopts two-stage drive (belt plate iis driven by auxiliary fine-pitch chain),which eliminates the mechanical nonsynchronous.
- The double belt also is equipped flexible tight system to make the operation more stable and reliable.
- The width of double belt plate can reach to 267 mm by adopting high quality special material and elaborate welding heat treatment.
- The side and bottom moulds device of double belt has powerful functions which can produce the sandwich panels from 20-200mm in thickness and 600-1240mm in width.
