To understand the rock wool sandwich panel production line, it is first necessary to clarify the composition and performance of the exterior wall rock wool sandwich panel. The rock wool sandwich panel is a composite material composed of three parts: the upper and lower surface layers and the middle core layer. The surface layers are usually made of color-coated steel plates, aluminum-magnesium-manganese plates and other metal materials, which have the characteristics of light weight, high strength and good corrosion resistance; the core layer is rock wool, a porous thermal insulation material made of natural basalt, diabase and other volcanic rocks through high-temperature melting, fiberization, and addition of appropriate binders. Rock wool has excellent thermal insulation, fire resistance and sound absorption properties. The production line integrates the processes of material uncoiling, leveling, core material laying, compound pressing, cutting and finished product stacking, realizing the continuous and automated production of rock wool sandwich panels. The rationality and advanced nature of the production process directly determine the quality and performance of the final products.

The working process of the exterior wall rock wool sandwich panel production line can be divided into several key stages, each of which is closely linked and mutually coordinated to ensure the smooth progress of production. The first stage is the preparation of surface materials. The surface metal coils (such as color-coated steel coils) are transported to the uncoiling machine, which uncoils the coils stably under the control of the frequency converter to avoid damage to the surface of the metal plates. After uncoiling, the metal plates enter the leveling machine. Due to the deformation caused by rolling during the storage and transportation of the coils, the leveling machine uses multiple sets of leveling rollers to flatten the metal plates, ensuring the flatness of the surface layers, which is crucial for the subsequent compounding quality. Some advanced production lines are also equipped with a surface cleaning device, which removes dust, oil stains and other impurities on the surface of the metal plates through brushing and air blowing, enhancing the bonding force between the surface layers and the core layer.

The second stage is the processing and laying of the core material. Rock wool, as the core material of the sandwich panel, needs to be processed into a specified thickness and width before laying. The rock wool blanket or rock wool board is transported to the cutting device through the conveyor belt, and the cutting machine cuts the rock wool into the required size according to the production parameters set by the system. In this process, the precision of the cutting device is very important. If the size of the rock wool is inaccurate, it will lead to gaps or overlaps between the core material and the surface layers, affecting the thermal insulation performance and structural stability of the sandwich panel. After cutting, the rock wool core material is transported to the compounding platform through the automatic laying device, and is accurately laid between the upper and lower surface metal plates. Some production lines are also equipped with a core material compaction device, which appropriately compacts the rock wool to improve its density and ensure that the core material is closely combined with the surface layers.

The third stage is compound pressing and bonding. The upper and lower surface metal plates with the rock wool core material laid in between enter the compound pressing machine. The compound pressing machine uses the combined action of heat and pressure to bond the three layers of materials tightly. The temperature and pressure in this process need to be strictly controlled. The appropriate temperature can make the binder on the surface of the metal plates or the binder added between the layers melt, and the pressure can ensure that the three layers of materials are fully bonded without gaps. The compound pressing machine is usually composed of multiple sets of pressing rollers, which gradually apply pressure to the composite material, ensuring the uniformity of the bonding. After compound pressing, the composite material enters the curing zone. In the curing zone, the composite material is kept at a certain temperature for a period of time, so that the binder is fully cured, and the bonding strength between the layers is further enhanced. The curing time and temperature are determined according to the type of binder and the thickness of the sandwich panel, which directly affects the durability of the product.

The fourth stage is cutting and finished product processing. After curing, the continuous composite material enters the cutting machine. The cutting machine uses high-precision cutting tools (such as circular saws or plasma cutters) to cut the composite material into finished panels of specified length according to the production requirements. The cutting process needs to ensure the flatness of the cutting surface and the accuracy of the length, avoiding burrs or uneven cuts. After cutting, the finished panels are transported to the stacking device through the conveyor belt. The stacking device automatically stacks the finished panels neatly, which is convenient for storage and transportation. Some advanced production lines are also equipped with quality inspection devices, which detect the thickness, flatness, bonding strength and other indicators of the finished panels through sensors. Unqualified products are automatically sorted out, ensuring the quality of the delivered products.

The exterior wall rock wool sandwich panel production line has a series of technical characteristics that adapt to the needs of modern construction. First of all, it has a high degree of automation. From the uncoiling of the surface material to the stacking of the finished product, the entire production process is controlled by the PLC system, which reduces manual intervention, improves production efficiency, and avoids errors caused by manual operation. The operator only needs to set the production parameters through the man-machine interface and monitor the operation status of the equipment. Secondly, the production line has strong flexibility. It can produce sandwich panels of different specifications (different thicknesses, widths and lengths) by adjusting the production parameters, which can meet the needs of different construction projects. At the same time, it can also adapt to different types of surface materials and core materials, realizing the production of multiple types of composite panels. Thirdly, the production line has high production precision. The use of advanced servo control technology and high-precision sensors ensures the accuracy of each production link, such as the flatness of the surface layer, the size of the core material, the bonding uniformity and the cutting precision, which effectively guarantees the quality of the finished product. Finally, the production line is environmentally friendly and energy-saving. In the production process, the equipment adopts advanced dust removal and noise reduction devices, which reduces the emission of dust and noise, and meets the environmental protection requirements. At the same time, the optimized production process reduces energy consumption, improving the economic benefits of production.

The application of the exterior wall rock wool sandwich panel production line brings significant advantages to the construction industry and the production enterprises. For production enterprises, the automated production line greatly improves production efficiency. Compared with manual or semi-automatic production, the continuous production mode of the production line can increase the output by several times, shorten the production cycle, and reduce the production cost. The high degree of automation also reduces the demand for labor, reducing the labor cost and the risk of labor safety accidents. In addition, the stable operation of the production line and the high precision of production ensure the consistency of product quality, improve the competitiveness of enterprises in the market. For the construction industry, the mass production of rock wool sandwich panels by the production line provides a stable and high-quality material supply for construction projects. The rock wool sandwich panel has the advantages of light weight, which can reduce the self-weight of the building, reduce the cost of the foundation and the main structure. Its excellent thermal insulation performance can reduce the energy consumption of the building's heating and air conditioning, meeting the requirements of energy-saving buildings. The good fire resistance of rock wool can improve the fire safety level of the building, reducing the loss caused by fire. In addition, the rock wool sandwich panel has the characteristics of quick installation, which can shorten the construction period and improve the construction efficiency.

The exterior wall rock wool sandwich panel produced by the production line has a wide range of applications in the construction field. It is widely used in industrial plants, warehouses, workshops, commercial buildings, office buildings, residential buildings and other types of buildings.
