The structure of the rockwool sandwich panel production line with automatic cutting system is a modular integrated design, which is composed of multiple functional units that are closely linked and coordinated. The whole production line starts with the uncoiling unit, which is responsible for stably unwinding the surface materials (usually metal sheets such as color-coated steel or aluminum alloy) and conveying them to the next process through the guiding device. The surface materials need to go through the pre-treatment process first, where the surface is cleaned and slightly adjusted to ensure the flatness and bonding performance of the materials, so as to avoid bubbles or delamination in the subsequent composite process. After pre-treatment, the surface materials enter the glue spraying unit, where the high-pressure spray gun evenly sprays the adhesive on the inner surface of the surface materials. The adhesive used is usually a two-component polyurethane system, which has strong bonding strength and good weather resistance, and can form a firm combination between the surface materials and the rockwool core.

The rockwool core processing unit is another important part of the production line. The rockwool raw material, made of natural volcanic rock through high-temperature melting and fiber spinning, is conveyed to the shaping device in the form of slabs or rolls. In the shaping device, the rockwool 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. This three-layer structure is then sent to the double-track laminating unit, where it is pressed and bonded under a certain temperature and pressure. The laminating unit adopts a constant temperature control system to ensure that the adhesive fully cures and the three layers are tightly combined, while maintaining the flatness and structural stability of the panel.

The automatic cutting system is installed at the end of the laminating unit, which is the key to realizing the customization of product specifications. This system is composed of a precision positioning device, a cutting execution mechanism, a control system and a waste collection device. The precision positioning device uses photoelectric sensors and encoder technology to real-time detect the conveying speed and position of the composite panel, ensuring that the cutting position is accurate. The cutting execution mechanism usually adopts a circular saw blade or a hydraulic shear, which can be selected according to the thickness of the panel and the material of the surface layer. The circular saw blade is suitable for cutting panels with thicker surface layers, while the hydraulic shear is more suitable for thin panels, which can reduce the deformation of the surface layer during cutting. The control system of the automatic cutting system is connected with the main control system of the production line, and the operator can input the required length, width and other parameters through the human-machine interface. The system can automatically adjust the cutting speed and frequency according to the conveying speed of the panel, realizing non-stop cutting during continuous production, which greatly improves the production efficiency. The waste collection device collects the cutting waste in a centralized manner to avoid environmental pollution and material waste.

In addition to the main functional units, the production line is also equipped with auxiliary systems such as a central control system, a conveying system and a packaging system. The central control system adopts integrated control technology, which can monitor the operation status of each unit in real time, realize parameter linkage adjustment, fault self-diagnosis and alarm functions, and ensure the stable operation of the whole production line. The conveying system is composed of multiple conveyor belts with synchronous speed control, which ensures the smooth conveying of materials between each unit and avoids material accumulation or deviation. The packaging system automatically stacks and wraps the cut finished panels, which is convenient for storage and transportation. The modular design of the whole production line enables each functional unit to be flexibly combined and adjusted, and can be customized according to the production needs of different users, realizing the production of various types of rockwool sandwich panels.

The performance of the rockwool sandwich panel production line with automatic cutting system is reflected in multiple aspects such as production efficiency, product quality, operation stability and environmental protection. In terms of production efficiency, the continuous production mode of the production line and the non-stop automatic cutting system greatly shorten the production cycle. The production speed can be adjusted between 3 and 8 meters per minute according to the product specifications and material characteristics, and the annual output can reach hundreds of thousands of square meters, which can meet the large-scale production needs of enterprises. In terms of product quality, the precision control of each link ensures the stability of the panel performance. The automatic cutting system can achieve a cutting accuracy of ±0.5mm, which effectively avoids the size error caused by manual cutting, ensuring that the panels can be accurately spliced during construction. The constant temperature and pressure laminating process ensures that the bonding strength between the surface layer and the core layer is uniform, and the panels are not easy to delaminate or deform during long-term use.

The operation stability of the production line is guaranteed by the advanced control system and high-quality components. The central control system can realize the coordinated operation of each unit, and the fault self-diagnosis function can quickly locate the fault point, reducing the maintenance time and production loss. The key components such as the transmission mechanism and the cutting tool are made of wear-resistant and corrosion-resistant materials, which have a long service life and low maintenance cost. In terms of environmental protection, the production line is equipped with dust removal devices and waste treatment systems. The dust generated during the rockwool processing is collected by the dust removal device to avoid air pollution; the cutting waste is recycled and reused, reducing material waste. At the same time, the adhesive used in the production process does not contain harmful substances such as CFCs, HCFCs and asbestos, which is in line with environmental protection requirements.

The energy-saving performance of the production line is also worthy of attention. The constant temperature control system of the laminating unit adopts energy-saving heating elements and heat insulation materials, which reduces heat loss; the frequency conversion speed regulation technology is used in the transmission system, which can adjust the power consumption according to the production load, achieving the purpose of energy saving. In addition, the automatic control system reduces the number of operators, usually only 5-8 people are needed to complete the operation of the whole production line, which greatly saves labor costs and improves production efficiency.

According to the different structural characteristics, performance requirements and application scenarios of the products, the rockwool sandwich panels produced by this production line can be divided into multiple types. According to the type of surface material, they can be divided into color-coated steel rockwool sandwich panels, stainless steel rockwool sandwich panels and aluminum alloy rockwool sandwich panels.
