Sandwich panel making equipment is a set of integrated industrial machinery designed to produce sandwich panels, which are composite materials consisting of two outer facing layers and a middle core layer bonded together. These panels are widely used in various fields due to their excellent comprehensive performance, and the equipment that manufactures them plays a crucial role in ensuring the quality, efficiency and stability of the production process. The structure of sandwich panel making equipment is complex and systematic, integrating multiple functional modules that work together to complete the entire production process from raw material input to finished product output. Each component of the equipment has a specific function, and the rationality of its structure directly affects the production efficiency and product quality.

The basic structure of sandwich panel making equipment usually includes an uncoiling and leveling system, a forming system, a core material feeding and mixing system, a composite pressing system, a cutting system, a stacking system, and a control system. The uncoiling and leveling system is the starting part of the production line, mainly composed of uncoilers, leveling machines and guiding devices. Uncoilers are used to hold the coiled facing materials, such as color steel coils, aluminum coils or other metal coils, and feed them into the subsequent process at a stable speed. The dual winding machine configuration is often adopted to realize uninterrupted production, which avoids the need to stop the machine when replacing coils and greatly improves production efficiency. Leveling machines are equipped with high-precision leveling units, which can eliminate the internal stress of the coiled materials and ensure the flatness of the facing materials. The automatic centering device in the system can keep the materials moving stably, preventing deviation during the conveying process and ensuring the accuracy of subsequent processing. In addition, the shear welding system in this module can realize seamless connection of coil materials, ensuring the continuity of the facing materials and avoiding gaps that may affect the bonding effect with the core material.

The forming system is responsible for shaping the facing materials into the required cross-sectional shape, which is an important part affecting the appearance and structural strength of the sandwich panels. This system usually includes a multi-roll precision forming unit, servo drive technology and an online molding monitoring system. The multi-roll precision forming unit can gradually deform the facing materials through a series of rollers with specific shapes, and can quickly replace molds to meet the production needs of different types of panels, such as corrugated panels, flat panels or other special-shaped panels. Servo drive technology ensures high molding accuracy, with an error range of ±0.1 mm, which can effectively guarantee the consistency of the panel size. The online molding monitoring system can real-time monitor the forming process, adjust parameters in time when deviations are found, and avoid defective products caused by molding errors. The modular design of the forming system also makes it more flexible, which can be flexibly configured according to different product specifications and requirements.

The core material feeding and mixing system is tailored according to the type of core material, and its main function is to accurately feed and evenly mix the core material, ensuring that the core material can be tightly bonded with the facing materials. For polyurethane core materials, the system is equipped with a high-pressure foaming machine, an accurate metering mixing system and a temperature and pressure closed-loop control system. The high-pressure foaming machine can inject the mixed polyurethane raw materials into the gap between the two facing materials, and the accurate metering mixing system ensures that the mixing ratio of the raw materials is accurate, with an error of less than 1%. The temperature and pressure closed-loop control system can effectively control the foaming temperature and pressure, ensuring the foam quality and avoiding problems such as uneven foaming or insufficient foaming. For rock wool, glass wool and other fibrous core materials, the system is equipped with an automatic laying device, which can evenly lay the core material between the two facing materials, ensuring the uniformity of the core material thickness. For EPS core materials, the system is equipped with a special feeding device and a glue providing system, which can realize the uniform bonding of the EPS core material and the facing materials, and the glue is applied evenly without pollution.

The composite pressing system is the key link to realize the bonding of the facing materials and the core material, which directly affects the bonding strength and overall performance of the sandwich panels. This system usually adopts a double belt continuous press or a multi-roll composite system, with an adjustable pressure range of 5-50 tons, which can be adjusted according to different core materials and panel thicknesses. The temperature zoning control function allows the system to adapt to different core materials, as different core materials have different curing temperature requirements. For example, polyurethane core materials need a higher curing temperature, while rock wool core materials have lower requirements on temperature but higher requirements on pressure. The automatic thickness adjustment function of the composite pressing system can ensure the thickness accuracy of the sandwich panels, with an error of ±0.2 mm, which can meet the different thickness requirements of various application scenarios. During the pressing process, the system can realize continuous and stable pressing, ensuring that the facing materials and the core material are tightly bonded, without delamination or hollowing.

The cutting system is used to cut the continuous sandwich panels into the required length, which requires high cutting accuracy and efficiency. Common cutting devices include CNC flying saws, laser cutting machines and band saws. CNC flying saws and laser cutting machines have high cutting accuracy, with a length measurement accuracy of ±1 mm, and can realize automatic cutting without stopping the machine, which is suitable for large-scale continuous production. The laser cutting machine also has the advantages of smooth cutting surface and no burrs, which can improve the appearance quality of the finished products. The cutting system is also equipped with an automatic length measurement system, which can accurately measure the length of the panels and adjust the cutting position in real time according to the set length. In addition, the moving stroke of the cutting system is designed to be long, which can extend the service life of the cutting tool and reduce the frequency of tool replacement.

The stacking system is responsible for automatically stacking the cut finished panels, which can reduce manual labor and improve production efficiency. This system usually adopts robotic arms or vacuum suction cups to realize automated stacking, and can automatically count and sort the finished products. The maximum stacking height can reach 2.5 meters, which saves storage space. The stacking system is also equipped with a conveying device, which can transport the stacked panels to the packaging area or the storage area, realizing the continuity of the production process. Some advanced stacking systems also have the function of automatic packaging, which can wrap the stacked panels to prevent damage during transportation and storage.

The control system is the "brain" of the entire sandwich panel making equipment, which integrates PLC, industrial computer and other control technologies to realize the automatic control of the entire production process. The PLC + industrial computer dual control system can ensure the stability and reliability of the equipment operation, and can realize the cloud storage and analysis of production data, which is convenient for operators to monitor and manage the production process. The control system also has a fault self-diagnosis and remote maintenance function, which can quickly find out the fault location and cause when the equipment fails, and realize remote maintenance through the network, reducing the maintenance time and cost. The intelligent optimization algorithm of process parameters can automatically adjust the production parameters according to the raw material characteristics and product requirements, ensuring the stability of product quality. The control panel of the system is simple and easy to operate, and operators can complete the setting and adjustment of parameters through the touch screen, reducing the difficulty of operation.

In addition to the basic structure, the performance of sandwich panel making equipment is also reflected in many aspects, such as production efficiency, precision, energy saving and environmental protection, and flexibility.
