Color Steel Rock Wool Sandwich Panel Equipment

Color steel rock wool sandwich panel equipment is a specialized mechanical system used for automated production of color steel rock wool sandwich panels. Through precise design and efficient process flow, it combines color coated steel plates with rock wool core materials into a structurally complete building panel. This type of equipment represents the high-tech level of modern building materials machinery manufacturing, and its performance directly determines the quality and production efficiency of the final product.

The core working principle of the color steel rock wool sandwich panel plant is to tightly bond the upper and lower layers of color coated steel plates (usually galvanized steel plates or aluminum zinc coated steel plates, with a thickness between 0.4-0.8mm) and the middle layer of rock wool core material (with a density of generally 120-150kg/m ³) through high-pressure composite technology. When the equipment is running, the color steel plate first goes through the unwinding and leveling process, and then enters the forming machine to be rolled into specific plate shapes (such as tongue and groove or corrugated). At the same time, the rock wool core material is precisely cut and transported between two layers of steel plates. Finally, the composite process is completed through multiple processes such as gluing, pressing, and heating.

From the perspective of equipment composition, a complete color steel rock wool sandwich panel production line mainly includes the following functional modules:

• Uncoiling system: used for loading and unfolding color steel sheet coils, usually equipped with automatic centering devices
  

• Forming unit: The flat plate is gradually pressed into the desired waveform through multiple rollers, which is the key part determining the accuracy of the plate shape
  

• Rock wool conveying device: Accurately control the conveying speed and position of rock wool to ensure that the core material is flat and in place
  

• Glue coating system: high-pressure spraying or rolling coating is used to evenly apply polyurethane foam adhesive on the bonding surface
  

• Composite host: The core part is permanently bonded with three layers of materials through precise temperature and pressure control
  

• Cutting unit: automatically cuts according to the set length, with two cutting methods: hydraulic cutting and sawing
  

• Stacking device: Automatically stack finished boards neatly, reducing manual handling

From the perspective of production process flow, the production of color steel rock wool sandwich panels can be divided into three main stages: preliminary preparation (including raw material inspection and equipment parameter setting), forming and composite (steel plate forming and rock wool composite are carried out simultaneously), and post-processing (cutting and trimming and quality inspection). Compared with traditional on-site composite methods, the factory prefabrication production method has significant advantages such as controllable quality, high efficiency, and not being affected by weather, which is also where the value of color steel rock wool sandwich panel equipment lies.

As a highly specialized industrial equipment, the performance of color steel rock wool sandwich panel equipment depends on the design concept and manufacturing process of the core structure. In recent years, with the development of materials science and automation technology, significant breakthroughs have been made in structural optimization and technological innovation of such equipment, greatly improving production efficiency and product quality stability.

The modern color steel rock wool sandwich panel equipment is mainly composed of three functional modules, each of which is carefully designed for specific process requirements:

High precision adhesive coating system

• Using stainless steel adhesive storage tanks with transparent observation windows and dust covers to ensure the cleanliness of the adhesive solution
  

• The uniquely designed sponge application pad is matched with a through-hole application tube to achieve precise control of the adhesive amount (within ± 2% error)
  

• The patent observation film design facilitates real-time monitoring of adhesive uniformity by operators, preventing missed or accumulated coating
  

• The glue temperature automatic control system maintains the optimal viscosity and adapts to different environmental production conditions

Intelligent extrusion device

• The combination structure of the first buffer spring and the special texture pressure roller provides adjustable pressure of 20-100kN
  

• The pressure adaptive adjustment system automatically adjusts according to the thickness of the sheet, ensuring the tightness of the interlayer bonding
  

• The surface of the pressure roller is laser engraved with texture, which increases the friction coefficient by 42% compared to traditional metal rollers
  

• The hydraulic servo system ensures stable pressure and controls the fluctuation range within ± 5%

Flexible collection component

• The second buffer spring and the clamping plate linkage mechanism form a dual damping system
  

• The hydraulic damping device can absorb over 90% of the impact energy from the falling of the sheet metal
  

• The automatic centering device ensures that the boards are stacked neatly and the misalignment error is less than 3mm
  

• The combination of photoelectric sensing system and robotic arm achieves unmanned stacking, reducing labor intensity
