The rock wool sandwich panel machine is a highly automated professional mechanical system specifically designed for manufacturing composite panels consisting of two layers of metal panels (usually galvanized steel or aluminum plates) and an intermediate rock wool insulation layer. This sandwich structured board has become an indispensable material in the modern construction industry due to its excellent fire resistance, sound insulation, and thermal insulation properties.
A complete rock wool sandwich panel production line usually consists of multiple functional modules, including unwinding system, forming system, rock wool conveying system, bonding system, hot pressing curing system, cutting system, and stacking system. These systems coordinate their work through precise control technology to achieve fully automated production from raw materials to finished products.
Open book and pre-processing system
The uncoiler is the starting point of the production line, responsible for smoothly unfolding the rolled metal sheets. Modern uncoiler machines often adopt a dual head design, which can achieve uninterrupted coil changing and ensure production continuity. After uncoiling, the sheet enters the pre-processing stage:
Cleaning device: Remove oil stains on metal surfaces through brush rollers and chemical cleaning agents
Leveling machine: eliminates the bending stress of the coil and ensures the flatness of the board
Film laminating machine: Cover the metal surface with a protective film (coating treatment is carried out first when producing colored sheets)
Metal panel forming system
The molding system is the heart of the production line, consisting of multiple sets of precision rolling molds:
Continuous roll forming machine: gradually process the flat plate into the desired cross-sectional shape through 12-24 sets of rollers of different shapes
Edge bending unit: precise control of the bending angle and shape of the panel edge
Online monitoring system: laser rangefinder for real-time detection of forming size accuracy
Rock wool processing system
Rock wool processing is the core technical link in the production of rock wool sandwich panels:
Rock wool unpacking machine: automatically disassembles the rock wool packaging and sends it into the conveyor line
Rock wool slitting machine: high-precision CNC cutting, tolerance controlled within ± 0.5mm
Rock wool splicing machine: achieving seamless splicing of rock wool strips through hot air welding
Dust removal device: negative pressure suction system ensures a clean production environment
Composite and Adhesive Systems
The bonding quality directly affects product performance and service life:
Two component polyurethane adhesive automatic spraying system: precise control of adhesive ratio and dosage by metering pump
High pressure foaming system (optional): Some production lines can inject polyurethane into the gaps of rock wool to increase strength
Preloading device: preliminarily fix the relative position between the panel and the rock wool
Hot press curing system
The composite board enters the hot pressing zone to complete the final molding:
Double belt continuous hot press machine: temperature controlled between 80-120 ℃, pressure 20-50 tons
Temperature control system: zone temperature control ensures uniform heating of the board
Cooling section: gradually cool down to avoid deformation of the board
Cutting and Stacking System
CNC flying saw: driven by servo motor, cutting accuracy ± 1mm
Waste recycling device: automatic collection of scraps
Automatic stacker crane: The robotic arm stacks finished products in a preset mode
Packing machine: automatic wrapping of protective film to prevent transportation damage
Modern rock wool sandwich panel production machines generally adopt advanced automation control systems:
PLC control system: realizing equipment linkage control
Human computer interface: 10-15 inch touch screen, supporting multilingual operation
Remote monitoring: 4G/5G networking enables remote diagnosis and maintenance
MES system integration: Integrate with factory management system data to achieve production information management
Intelligent detection: Machine vision system automatically recognizes surface defects
Equipment selection considerations:
Production demand: Select the model based on the target product specifications (thickness, width)
Factory conditions: Evaluate the length, height, and load-bearing capacity of the site
Energy configuration: Requirements for infrastructure such as electricity and compressed air
Daily maintenance focus:
Roller maintenance: Regular cleaning and lubrication to prevent material adhesion
Transmission system: Check the tension and wear of chains and belts
Electrical system: Regularly check sensor sensitivity and circuit insulation
Hydraulic system: Monitor oil level and quality, regularly replace filter elements
Tool management: Keep cutting tools sharp and establish replacement records
