The overall structural layout of the cold storage sandwich panel line follows a scientific sequential processing logic, with all functional units arranged in a linear and coordinated configuration to ensure uninterrupted production circulation. The complete production system consists of multiple interconnected functional modules, including raw material unwinding and pretreatment units, surface material forming mechanisms, high-precision core material proportioning and injection systems, continuous composite pressing devices, constant-temperature curing cabins, fixed-length cutting units, and automatic conveying and stacking systems. Each module operates in synchronous linkage under unified electrical control, avoiding the semi-automatic disconnection and manual material transfer links that plague traditional production equipment. The front-end modules are responsible for sorting and shaping metal surface materials, eliminating surface wrinkles and deformation to lay a foundation for flat and uniform finished panels. The middle core modules complete the key foaming and composite bonding process, while the rear-end equipment realizes precise shaping and automatic collection of finished products. This integrated structural design not only simplifies the production process but also greatly improves the overall operational stability of the equipment, ensuring consistent production quality in long-term continuous operation.

Raw material pretreatment and surface layer forming constitute the initial key stage of the entire production process, directly determining the surface flatness and overall appearance quality of finished sandwich panels. The line is equipped with automatic unwinding equipment that stably releases coiled surface materials, with auxiliary pressing and straightening devices to prevent material loosening and deviation during operation. In the pretreatment process, the surface materials undergo multi-stage leveling and trimming treatment to remove edge burrs and uneven parts, ensuring the consistency of material specifications. Meanwhile, professional forming rollers conduct gradual cold bending forming on the surface materials, processing flat coiled materials into specific groove and joint structures required for cold storage panels. These customized structural designs facilitate tight assembly and seamless splicing between panels in later cold storage construction. The entire pretreatment and forming process adopts automatic speed tracking control, realizing synchronous operation with the main production line. This avoids dimensional errors caused by asynchronous material supply and processing, effectively improving the yield rate of semi-finished products and laying a solid foundation for subsequent core material composite processing.

Core material proportioning and continuous foaming are the core functional links of the cold storage sandwich panel line, which fundamentally determine the thermal insulation performance and structural firmness of finished panels. The line is equipped with a high-precision automatic proportioning system that accurately mixes multiple raw materials for thermal insulation core materials according to set proportions. The system maintains stable material output pressure and flow rate throughout the process, avoiding uneven material mixing that may cause inconsistent foaming density. After precise proportioning, the mixed liquid core material is evenly injected between the upper and lower formed surface materials through a high-pressure injection device. In a closed and temperature-controlled processing environment, the core material undergoes uniform expansion and foaming, gradually filling the entire gap between the surface layers. The controllable foaming environment ensures that the internal foam structure is fine and uniform, without hollowing, cracking or uneven density. A real-time monitoring mechanism is integrated in the foaming process to dynamically adjust injection volume and foaming parameters according to production speed and panel thickness requirements, ensuring that each batch of panels maintains stable thermal insulation and pressure resistance performance.

Continuous composite pressing and constant-temperature curing processes are crucial for enhancing the bonding strength and structural stability of sandwich panels. After the core material is injected and initially foamed, the semi-finished panel enters the double-belt pressing device of the production line, which applies uniform and stable pressure to the entire panel surface. This pressing mode effectively eliminates gaps between the core material and surface materials, achieving full and tight composite bonding without local degumming or separation. The pressing equipment maintains constant pressure and running speed during operation, ensuring consistent thickness and flatness of the entire panel. Subsequently, the panels enter the independent constant-temperature curing cabin for staged heat preservation and curing treatment. The stable temperature environment in the cabin promotes the complete reaction and solidification of the core material, optimizing the internal molecular structure of the foam and enhancing the overall toughness and compression resistance of the panel. The integrated pressing and curing process avoids the quality instability caused by natural curing in traditional production modes, greatly improving the bonding firmness and structural durability of finished panels, enabling them to withstand long-term low-temperature and high-humidity working environments in cold storage.

Precision cutting and edge finishing processes ensure the dimensional accuracy and assembly adaptability of finished cold storage sandwich panels. After completing curing and shaping, the continuous long-panel products are transported to the fixed-length cutting station through the automatic conveying system. The line adopts a flying saw cutting structure, which can complete fixed-length cutting without stopping the production line, effectively improving production continuity and efficiency. The cutting system supports flexible adjustment of cutting length according to different usage needs, realizing diversified production of panels of various specifications. After cutting, the edge trimming device automatically polishes and cleans the panel edges, removing residual foam flash and irregular burrs generated during production. For panels with tongue-and-groove or cam-lock joint structures dedicated to cold storage, the equipment can complete precise edge shaping to ensure accurate matching between panels. The entire cutting and finishing process adopts automated parameter control, with high cutting precision and neat panel sections, avoiding dimensional deviations and edge defects that affect on-site assembly. This ensures that the finished panels can achieve seamless splicing during cold storage installation, guaranteeing the airtightness and thermal insulation effect of the overall cold storage enclosure structure.

Automatic conveying, stacking and packaging systems realize the intelligent finishing of finished products and improve production operational efficiency. After passing the cutting and edge finishing process, qualified panels are automatically conveyed to the finished product sorting area through the synchronous conveying device. The conveying system operates stably and synchronously with the front-end production process, avoiding panel extrusion, collision and surface damage caused by speed mismatch. The production line is equipped with a hydraulic automatic stacking mechanism, which can neatly stack panels according to set specifications. The mechanical stacking mode replaces manual handling, effectively reducing labor intensity and avoiding panel deformation and surface scratches caused by manual operation. After stacking, the finished panels enter the automatic packaging link, where professional wrapping materials are used for overall sealing and protection to prevent dust, moisture and mechanical damage during transportation and storage. The integrated post-processing system realizes unmanned operation of the finished product link, greatly improving production efficiency, standardizing finished product storage standards, and facilitating centralized transportation and on-site construction arrangement of panels.

The automated control system and intelligent detection function endow the cold storage sandwich panel line with high stability and low defect rate in long-term operation. The entire production line is centrally controlled by a programmable logic controller, which uniformly regulates the operating speed, material proportioning, pressing pressure, curing temperature and cutting parameters of each functional module. The intelligent control mode realizes synchronous linkage of all processes, automatically adjusting operating parameters according to different panel thicknesses and material types to meet diversified production demands. Meanwhile, multiple real-time detection devices are embedded in key production links, which can monitor panel thickness, surface flatness, bonding state and foaming density in real time during the production process. Once minor parameter deviations or potential quality problems are detected, the system will automatically fine-tune equipment parameters to eliminate defective products at the source. This intelligent production and detection mode not only reduces manual intervention and operation errors, but also ensures the long-term stable output of high-quality panels, greatly reducing production loss and improving the comprehensive production benefit of the line.
