The structure of the rockwool sandwich panel line is modular and integrated, consisting of multiple functional units that work closely together to complete each link of the production process, from the uncoiling of surface materials to the stacking of finished products. Each functional unit is designed with high precision and rationality, ensuring the smooth operation of the entire production line and the consistency of product specifications.

The core structure of a rockwool sandwich panel line mainly includes uncoiling units, roll forming units, rockwool core processing units, glue spraying units, composite laminating units, automatic cutting units, conveying units, stacking units, and electrical control units. Each unit undertakes specific functions and is closely connected to form a complete production chain. The uncoiling unit is the starting point of the production line, responsible for stably unwinding the surface materials, which are usually metal coils such as color-coated steel plates or aluminum alloy plates. This unit is equipped with hydraulic control and automatic centering functions to ensure that the metal coils are fed uniformly without deviation, which is crucial for maintaining the flatness and dimensional accuracy of the surface materials. The uncoiling unit is also equipped with a tension control device to adjust the tension of the metal coils according to different material thicknesses, preventing the surface materials from being stretched or wrinkled during the uncoiling process. Some advanced uncoiling units are also equipped with feeding trolleys and auxiliary support structures to facilitate the loading and unloading of heavy metal coils, improving the convenience of operation.

The roll forming unit is a key part of the rockwool sandwich panel line, responsible for shaping the surface materials into the required cross-sectional profiles. This unit uses a series of sequentially arranged rollers with precise contours to gradually bend the flat metal sheets into shapes such as corrugated, trapezoidal, or flat panels. The rollers are made of high-quality steel that has undergone quenching treatment and precision machining, ensuring high wear resistance and dimensional stability. The forming speed of the roll forming unit is adjustable, which can be adjusted according to the thickness of the surface materials and the complexity of the profile, ensuring the forming quality and production efficiency. Some advanced roll forming units adopt a cassette-type or rail-wheel design, allowing for quick replacement of roller sets to produce different types of panels, thereby enhancing the production flexibility of the line. After forming, the surface materials are conveyed to the next process through a guiding device, ensuring smooth connection between processes.

The rockwool core processing unit is another important component of the rockwool sandwich panel line, responsible for processing the rockwool raw materials into core layers that meet the production requirements. Rockwool raw materials are usually made of natural volcanic rock, such as basalt, which is crushed into uniform particles and then melted at high temperatures exceeding 1500℃ to form molten magma. The molten magma is then sent to a high-speed rotating centrifuge, where it is stretched and shredded into extremely fine fibers under the action of strong centrifugal force. During this process, a certain amount of binder, mainly phenolic resin, and dust-proof oil are uniformly sprayed on the fibers to enhance their cohesion and prevent dust generation. The fibers coated with binder fall onto a collection belt in a settling chamber, forming a loose and uniform rockwool blanket, which is then conveyed to the shaping device. In the shaping device, the rockwool blanket is adjusted to the required thickness and density, and the fiber direction is optimized—usually arranged vertically to enhance the mechanical strength and thermal insulation performance of the final panel. The shaped rockwool core is then accurately conveyed between the upper and lower surface materials that have been sprayed with adhesive, forming a three-layer structure of upper surface material, rockwool core, and lower surface material.

The glue spraying unit is responsible for applying adhesive to the inner surface of the surface materials to ensure a firm bond between the surface materials and the rockwool core. The adhesive used is usually a two-component polyurethane system, which has strong bonding strength, good weather resistance, and excellent aging resistance, ensuring that the sandwich panels do not delaminate or fall off during long-term use.

Some advanced glue spraying units are equipped with automatic glue mixing and feeding systems, which can automatically mix the two-component adhesive in a certain proportion and continuously supply glue to the spray guns, improving the stability and uniformity of glue application. After glue spraying, the surface materials are conveyed to the composite laminating unit to complete the combination with the rockwool core.

The composite laminating unit is responsible for pressing the upper surface material, rockwool core, and lower surface material into an integrated sandwich panel. This unit adopts a double-belt pressing structure, which uses two parallel conveyor belts to apply uniform pressure to the three-layer structure, ensuring that the adhesive is fully cured and the three layers are firmly bonded. The conveyor belts are made of high-temperature resistant and wear-resistant materials, and the pressing pressure and temperature can be adjusted according to the production needs to adapt to different types of surface materials and rockwool cores. The composite laminating unit is also equipped with a heating system, which uses hot air circulation heating to maintain the appropriate temperature for adhesive curing, accelerating the curing speed and improving the bonding quality. After laminating, the composite panel is conveyed to the automatic cutting unit for cutting.

The automatic cutting unit is used to cut the continuous composite panel into finished products of the required length. This unit adopts a non-stop cutting design, which can cut the panel while the production line is running, ensuring continuous production and improving production efficiency. The cutting tool is usually a band saw or a circular saw with high sharpness and wear resistance, which can ensure smooth cutting edges and accurate dimensional accuracy. The cutting length is controlled by a PLC system, which can be set according to the customer's requirements, and the cutting accuracy can reach ±1mm, meeting the strict requirements of various application scenarios. After cutting, the finished products are conveyed to the stacking unit through the conveying unit.

The conveying unit runs through the entire production line, responsible for conveying materials between each functional unit. The conveying unit is composed of conveyor belts, rollers, and guiding devices, which are designed according to the layout of the production line and the characteristics of the materials. The conveyor belts are made of high-strength and wear-resistant materials, ensuring stable operation and long service life. The speed of the conveying unit is synchronized with the production speed of other units, ensuring the smooth flow of materials and avoiding material accumulation or stagnation. The stacking unit is the end of the production line, responsible for stacking the finished rockwool sandwich panels in an orderly manner for storage and transportation. The stacking unit adopts an automatic stacking design, which can adjust the stacking height and stacking method according to the size and weight of the finished products, reducing manual operation and improving stacking efficiency. Some advanced stacking units are also equipped with packaging devices, which can wrap the stacked panels to prevent damage during transportation.
