This professional production system is developed to meet the growing market demand for high-performance, multi-functional and long-service-life building enclosure materials, effectively combining the excellent fire resistance and sound insulation characteristics of rock wool core materials with the lightweight thermal insulation advantages of foam interlayers and the high-strength protective properties of metal surface plates, realizing the one-piece integrated molding of multi-layer composite structures through automated mechanical operation without excessive manual intervention in the core production links. As the core supporting equipment for the production of modern energy-saving and fireproof building materials, the overall structural design of the rock wool foam sandwich panel production line follows the concept of modular integration and efficient collaborative operation, and each functional module is closely connected and precisely matched in the production process, ensuring that every production link from raw material feeding to finished product stacking can be carried out stably, continuously and efficiently, and the produced rock wool foam sandwich panels have stable structural consistency, uniform performance parameters and excellent comprehensive applicability, which can adapt to various complex building construction environments and long-term service working conditions.

The overall structural composition of the rock wool foam sandwich panel production line is composed of multiple core functional modules and auxiliary supporting mechanical components, each of which undertakes an irreplaceable key task in the whole production process and jointly forms a closed-loop automated production system with smooth operation and precise coordination. The front-end part of the entire production line starts with the raw material unwinding and feeding module, which is responsible for stably placing and continuously outputting the metal surface plates used for the upper and lower layers of the sandwich panels, including galvanized steel plates and aluminum alloy plates with different thicknesses and surface treatments. This module is equipped with stable tension control devices and automatic deviation correction structures, which can effectively avoid the deviation and wrinkling of metal plates during the unwinding and conveying process, ensure the flatness and dimensional accuracy of the surface plates entering the subsequent processing links, and lay a solid foundation for the subsequent composite molding of panels. Closely connected with the feeding module is the roll forming and surface pretreatment unit, which carries out continuous cold roll forming on the unwound metal plates through multiple groups of precision arranged forming rollers, bending and pressing the metal plates into the required plate shape and edge structure according to the production specifications of different sandwich panels. At the same time, this unit also completes the surface cleaning and simple protection treatment of the metal plates, removing surface dust, oil stains and impurities that affect the bonding effect, ensuring that the subsequent adhesive can be closely combined with the metal surface without gaps and peeling hidden dangers.

The middle core part of the production line is the rock wool core material processing and foam filling composite module, which is the most critical structural section determining the core performance of the finished sandwich panels. This module is equipped with automatic rock wool slitting and cutting equipment, which can cut the whole roll or whole block rock wool raw materials into core strips and core plates with precise width and thickness according to the preset panel specifications, and complete the directional arrangement and dense assembly of rock wool fibers through the internal flipping and arranging device, effectively enhancing the overall structural stability and compression resistance of the rock wool core layer. Adjacent to the rock wool processing equipment is the automatic foam feeding and pouring unit, which quantitatively injects high-efficiency thermal insulation foam materials into the gaps around the rock wool core layer and between the composite layers according to the set proportion, realizing the organic combination of rock wool fireproof core and foam thermal insulation interlayer. Following the core material processing link is the automatic adhesive spraying and gluing unit, which evenly sprays high-performance composite adhesive on the inner surfaces of the upper and lower metal plates and the contact surfaces between the rock wool core and foam interlayer through a precise automatic spraying system. The spraying dosage and spraying range are accurately controlled by the mechanical control system, ensuring that each bonding surface can obtain uniform and sufficient adhesive coverage, avoiding local weak bonding and degumming problems, and greatly improving the overall bonding strength and structural integrity of the composite panels.

The rear-end core functional structure of the production line includes the double-belt thermal pressure composite shaping system and the fixed-length cutting and finishing module, which undertake the final composite molding and size standardization processing of the sandwich panels. The thermal pressure composite system adopts a closed double-belt transmission and heating pressure structure, which can apply stable and uniform pressure and constant temperature heating environment to the preliminarily composited multi-layer plates, promoting the rapid curing and hardening of the adhesive, realizing the tight integration of metal surface plates, rock wool core layer and foam interlayer into an integrated structure, and effectively eliminating the internal gaps and structural looseness of the composite panels. The temperature and pressure parameters of the thermal pressure process can be adjusted according to different raw material characteristics and panel production requirements, ensuring that the adhesive reaches the best bonding effect without damaging the structural performance of rock wool and foam materials. After thermal pressure curing and preliminary shaping, the continuous long composite plates are transported to the fixed-length cutting module, which uses high-precision vertical cutting and shearing equipment to cut the continuous plates into finished panels of standard length according to the actual use requirements, and completes the edge trimming and deburring treatment of the panel ends to ensure the flatness and neatness of the panel edges without burrs and deformation. The final part of the entire production line is the finished panel conveying and automatic stacking module, which automatically transports the cut qualified finished panels to the stacking area through the conveying device, and completes orderly stacking and arrangement through the automatic stacking machine, facilitating the subsequent transportation, storage and loading and unloading of finished products, realizing the full automation of the entire production process from raw materials to finished products without manual handling in the middle links.
