Description

TECHNICAL FIELD

[0002] The refrigeration truck carriage plate is the core component of the heat preservation system, usually composed of two layers of high-strength faceplate sandwiching the heat preservation material, with excellent heat insulation, durability and air tightness. The carriage plate can effectively block the interference of the external environment on the temperature inside the carriage, ensuring that the temperature inside the vehicle is maintained within the set range, thereby protecting the quality and safety of refrigerated goods. Its excellent heat preservation effect not only is an important guarantee for the efficiency of cold chain transportation, but also is directly related to the operation cost and energy consumption performance of the vehicle, so it plays an important role in the design and manufacture of refrigerated trucks.

[0003] However, the current manufacturing process of refrigerated truck carriage plate has many problems. The traditional carriage plate is processed by bonding three layers of material plates, which results in a relatively large overall weight, which is not conducive to the lightweight of the vehicle, thereby increasing fuel consumption and transportation cost. At the same time, the large use of chemical adhesives not only increases the production cost, but also poses a potential threat to the environment. In addition, the self-weight of the bonding material further increases the weight of the carriage plate, which is not conducive to improving the energy-saving performance of the vehicle. During the processing, the bonding process has high requirements for equipment and operating conditions, and the production efficiency is low, which is difficult to meet the needs of large-scale production. Moreover, the bonding quality is easily limited, which may cause uneven bonding or material delamination, resulting in reduced heat insulation performance and shortened service life of the product. In summary, the existing process has significant shortcomings in environmental protection, lightweight, cost control, production efficiency and product quality, and needs to be optimized and upgraded.

[0035] In order to make the purpose, technical scheme and advantages of the utility model more clear and explicit, the following will further explain the utility model with examples. It should be understood that the specific examples described here are only used to explain the utility model, and are not used to limit the utility model.

[0036] In order to solve the problems of heavy weight, poor environmental protection, high cost, low processing efficiency and poor product quality in the processing and manufacturing of current refrigerated truck carriage plate, the utility model provides a foam sandwich panel processing device. In order to further explain the structure of the utility model, the following detailed description is combined with the drawings:

[0037] Please refer to Figure 1 and Figure 2 A foam sandwich panel processing device, comprising a lower die seat 1, a lower die 2, a movable upper die frame 3, a mold pressing hydraulic cylinder 4, an upper die 5, a side hook pulling unit 6 and a foaming material generating assembly 7.

[0038] The lower mold is installed on the lower mold base. Specifically, the lower mold base is a rectangular support platform, and its specific dimensions can be designed according to the size of the vehicle body panel to be used, with an area larger than the vehicle body panel to be processed.

[0039] The lower mold is a rectangular platform fixed to the lower template. The lower mold has a lower mold table surface for setting the lower chamber plate, which serves as the supporting plane for the lower chamber plate. The lower mold table surface is equipped with a limiting component, including a rectangular limiting frame. The inner side of the rectangular limiting frame forms a pressing groove whose shape matches the contour of the lower chamber plate. In this embodiment, specifically, fixed limiting blocks are evenly distributed around the lower mold table surface of the lower mold. The four edges of the rectangular limiting frame are located inside the limiting blocks. The ends of the four edges do not need to be joined, leaving corner openings to facilitate adjustment of the enclosure area. To make the size of the rectangular limiting frame adjustable, an expansion block is pressed between the fixed limiting block and the edges of the rectangular limiting frame. The expansion block includes a top plate that contacts both the fixed limiting block and the edges, and a screw connected to the two top plates by threads. By rotating the screw to adjust the length screwed into the top plate, the overall width of the expansion block is adjusted, thereby adjusting the distance between the edges and the fixed limiting block.

[0040] The movable upper mold frame forms a horizontally moving frame that moves above the lower mold platform. The function of the movable upper mold frame is to move the upper panel horizontally and linearly above the lower panel, ultimately aligning it with the vertical projection of the lower panel. Another function is to allow the foaming material generation assembly mounted on it to form a foaming material layer between the lower and upper panels during its movement. In other words, it is an active driving component that simultaneously completes the feeding of the upper panel and the formation of the foaming material layer. Specifically, in this embodiment, horizontal linear guide rails are provided on both sides of the lower mold base. The movable upper mold frame is a gantry-shaped traveling frame mounted on and moving horizontally along the horizontal linear guide rails. The gantry-shaped traveling frame includes support side frames located on both sides and a platform located between the two support side frames. The pressing hydraulic cylinder is mounted on the platform. Furthermore, the gantry-shaped traveling frame is a steel frame, with traveling wheels and traveling motor devices that drive the traveling wheels to rotate installed on the lower part of the supporting side frames on both sides. The platform is a flat steel hook frame, which is used to load the hydraulic cylinder for pressing the mold, the upper mold, and the foaming material generation assembly.

[0041] A foaming material generating assembly is installed on a movable upper mold frame. The assembly has a foaming material outlet installed at the forward travel end of the movable upper mold frame, which laterally supplies foaming material to the lower mold panel. Specifically, in this embodiment, the foaming material generating assembly has a discharge conduit 7-1. The discharge conduit is horizontally positioned and perpendicular to the horizontal movement direction of the movable upper mold frame. It is laterally positioned above the lower mold table, and axially spaced foaming material outlets are provided along the discharge conduit. A foaming agent nozzle frame is fixed to the front edge of the upper mold's forward side. A horizontally positioned, horizontally spanning the lower mold's support plane, is installed below the foaming agent nozzle frame. A plurality of nozzles capable of spraying foaming agent are evenly distributed axially at the lower part of the discharge conduit to ensure that foaming agent extends laterally (perpendicular to the upper mold's feeding direction) along the lower mold panel. During the horizontal linear movement of the foaming material outlet, a foaming agent layer covering the upper mold panel is ultimately formed.

[0042] The existing foam material generation assembly is primarily used to generate foam materials with excellent thermal insulation properties during the production process and precisely inject them into sandwich structures. This equipment typically consists of several core components, including a foaming agent supply system, a mixing system, an injection device, and a control system. The supply system precisely delivers raw materials to the mixing zone according to a set ratio, while the mixing system ensures the uniform blending of various foaming agent components, avoiding quality problems caused by uneven reactions. Next, the injection device precisely injects the generated foam material between the inner and outer panels of the sandwich structure, such as the body panel, forming a uniform foam layer. The control system monitors the entire process in real time, ensuring the quality of the foam material and the controllability of the reaction process through fine-tuning parameters. This existing foam material generation assembly effectively improves production efficiency, reduces raw material waste, and ensures higher product quality consistency and a longer service life through a stable production process.

[0043] The pressing hydraulic cylinder and the upper mold are mounted on a movable upper mold frame. The pressing hydraulic cylinder is connected to and drives the upper mold to move vertically. Please refer to [link / reference]. Figure 4The upper mold is mounted on the movable upper mold frame via a vertical guide mechanism 8. Specifically, in this embodiment, the vertical guide mechanism includes vertical racks 8-1 located at the four corners of the movable upper mold frame, gear seats 8-2 installed at the four corners of the movable upper mold frame, guide gears 8-3 meshing with the vertical racks installed in the gear seats, and the vertical racks vertically passing through the gear seats to form a vertical guide for the racks. All guide gears are connected via a synchronous transmission shaft 8-4 and a bevel gear 8-5. The lower end of the vertical rack is connected to the upper mold. The hydraulic cylinders for pressing the mold are vertically arranged; in this embodiment, there are four, facing the platform evenly distributed on the movable upper mold frame. The platform fixes the cylinder body of the hydraulic cylinders, and the piston rods of the hydraulic cylinders extend and retract vertically downwards, with the end of the piston rod connected to the upper mold. The vertical guide mechanism is a structure to ensure that the upper mold moves vertically in a horizontal and stable posture. Vertical racks are distributed and connected at the four corners of the upper mold. As a component to maintain balance, the upper end of the vertical rack is connected to the gear set and the synchronous transmission shaft. The gear set includes guide gears that mesh with the vertical racks. The guide gears are mounted on the frame through axles. This axle is then connected to other guide gears through a bevel gear set and a horizontally arranged synchronous transmission shaft, thereby ensuring the synchronization of the vertical racks.

[0044] The above structural design, by evenly distributing the hydraulic cylinders of the pressing mold at the four corners of the moving upper mold frame and utilizing the vertical guiding mechanism in conjunction with the meshing of the vertical rack and guide gears, ensures that the upper mold maintains a horizontal and stable posture during vertical movement. This structure effectively avoids tilting or instability caused by gravity imbalance or excessive local stress during mold movement, ensuring the uniformity and precision of the entire pressing process. The synchronous transmission design between the vertical rack and guide gears guarantees the synchronous movement of the upper mold in the vertical direction. All guide gears are connected to bevel gears via a synchronous transmission shaft, ensuring consistent movement of each guide gear, avoiding errors between different gears, and ensuring the stability and symmetry of the upper mold. This synchronous transmission mechanism makes the vertical movement of the mold more precise, thereby improving the quality of the processed products. This design uses gear meshing transmission and is connected by gear sets, bevel gear sets, and synchronous transmission shafts, reducing friction and wear between various components. While ensuring precise transmission, it reduces wear caused by uneven force, extends the service life of the equipment, and lowers maintenance costs. The vertical and evenly distributed hydraulic cylinders of the pressing mold ensure more uniform pressure application, avoiding force concentration in one direction. The stable driving force provided by the hydraulic system allows the upper mold to maintain smooth movement even under heavy loads, thus meeting the high-intensity operational requirements of large-scale production. This design guarantees smooth vertical movement of the upper mold, greatly improving alignment accuracy during the pressing process. This precise control makes the production process smoother, reducing downtime caused by error adjustments or mold misalignment, thereby improving production efficiency and shortening the production cycle. The vertical guide mechanism ensures the stability of the upper mold during movement, avoiding the risk of mold swaying or instability. Combined with precise synchronous transmission, operators can more easily control the equipment, reducing the risk of accidents due to improper operation and improving operational safety. Because the various components in this structural design, such as guide gears and synchronous transmission shafts, are independently set and connected, equipment adjustment and maintenance become more convenient. When a fault occurs or adjustments are needed, corrections can be made by adjusting the synchronous transmission system without requiring large-scale disassembly of the entire structure, improving equipment maintainability.

[0045] N side hook pull units are evenly arranged circumferentially on the side of the upper mold. Please refer to [link / reference]. Figure 3The side hook unit is equipped with a hook 6-1 for hooking onto the edge of the upper panel and a claw drive component for driving the hook to move outward. The lower mold side is equipped with a hook pull part that engages with the hook. In this embodiment, specifically, the claw drive component is a hook-lock hydraulic cylinder 6-2. The cylinder body of the hook-lock hydraulic cylinder is mounted on the side of the upper mold via a pin, the hook is mounted on the cylinder rod of the hook-lock hydraulic cylinder, and the hook pull part is a shaft located on the side of the lower mold. Specifically, several shaft seats are evenly distributed along the edge of the upper mold. The shaft seats are mounted on the cylinder body of the hook-lock hydraulic cylinder via pins. The hook-lock hydraulic cylinder swings around the pin as its pivot. The pin is parallel to the side of the upper mold, and the swinging allows the hook to swing inward and outward, thereby achieving hooking onto the edge of the upper panel or hooking onto the lower mold. The output of the yaw drive force can be achieved through a yaw drive motor that drives the pin shaft to rotate. In this embodiment, the yaw drive force output is a yaw drive hydraulic cylinder 6-3. The cylinder body of the yaw drive hydraulic cylinder is fixed to the inner side of the upper mold and is hinged to the bracket fixed to the upper mold. Its piston rod is hinged to the cylinder body of the hook lock hydraulic cylinder. The extension and retraction of the piston rod of the yaw drive hydraulic cylinder drives the hook lock hydraulic cylinder to yaw. In order to achieve synchronous yaw of the hook lock hydraulic cylinders of all side hook pulling units on the same side, the cylinder bodies of the yaw drive hydraulic cylinders of the side hook pulling units on the same side are connected by the same connecting rod frame. The piston rod of the yaw drive hydraulic cylinder is hinged to the connecting rod frame to drive all side hook pulling units on the same side to work synchronously. The cylinder body hinge axis and piston rod hinge axis of the yaw drive hydraulic cylinder are parallel to the axis of the pin shaft of the hook lock hydraulic cylinder to achieve the completion of the yaw action.

[0046] After the foaming agent layer is pressed onto the upper and lower body panels, the design of distributing the locking clamping force around the perimeter of the panels significantly improves product quality. Firstly, the peripheral distribution of the locking clamping force provides uniform and stable pressure, ensuring more even diffusion and curing of the foaming agent within the interlayer. This avoids defects such as voids, collapses, or inconsistent thickness caused by uneven local pressure, thereby improving the density and thermal insulation performance of the foam layer. Secondly, this design effectively enhances the tight bond between the foam layer and the inner and outer body panels, especially at the edges, where the connection is stronger, preventing delamination or peeling due to loose edges and improving the overall structural stability and service life of the body panels. Simultaneously, the uniform pressure distribution helps maintain the flatness of the body panels, preventing deformation or warping caused by uneven stress, thus ensuring consistency in appearance and function. Furthermore, this design optimizes the distribution of air bubbles within the foam layer, creating a more regular closed-cell structure, further enhancing the thermal insulation performance and compressive strength of the body panels. This peripherally distributed clamping method not only improves the production quality of the carriage panels, but also provides reliable technical support for large-scale production, helping to improve the product qualification rate and market competitiveness.

[0047] The side hook unit serves as both a hook for feeding the upper panel and a clamping mechanism for the upper and lower dies. This dual function simplifies the production process and reduces the need for additional components. Operators can perform feeding and clamping operations with a single device, avoiding frequent equipment changes and adjustments, significantly improving production efficiency and operational consistency. This dual-function design integrates these two functions into a single component, saving space and reducing the number of required parts. This not only improves the space utilization of the production line but also effectively reduces equipment procurement and maintenance costs. When clamping the upper and lower dies, the side hook unit ensures precise die alignment through precise force control. This accurate clamping force distribution prevents misalignment or uneven pressing caused by uneven clamping or loosening, thus ensuring the stability and high precision of the die during processing. By integrating two key functions into one component, system complexity and potential failure points are reduced, improving equipment reliability. With fewer operational steps, the probability of malfunctions is correspondingly reduced, enhancing equipment stability and maintainability. This design combines feeding and clamping functions into one, simplifying the operation process. Operators only need to focus on one function, reducing operational complexity and thus minimizing errors caused by improper operation, improving ease of use and safety. The side hook unit simultaneously performs two functions, contributing to better coordination between different parts of the equipment. Enhanced synchronization of feeding and clamping actions results in smoother mold pressing, reducing potential asynchrony or conflict between devices and improving the overall smoothness of the production process. The integrated design makes the system more flexible in responding to different production needs. For example, in different production batches, the force and position of feeding and clamping can be adjusted as needed. The system can better adapt to upper panels and molds of different specifications and sizes, enhancing the equipment's adaptability and versatility.

[0048] In this embodiment, the upper mold is further further equipped with a heating component uniformly configured to heat the upper panel. The heating component provides uniform heat to the upper panel, maintaining its surface temperature within a suitable range for the curing of the foamed material. Under thermal conditions, the foamed material can complete chemical reactions (such as foaming agent decomposition and cross-linking curing) more quickly, thereby accelerating the foam layer molding process and improving production efficiency. Under the action of the heating component, the surface temperature of the upper panel increases, reducing the interfacial viscosity with the foamed material and promoting intermolecular interpenetration and cross-linking. This effectively improves the adhesion between the foamed layer and the upper panel, forming a tighter interfacial bond. Uniform heating avoids differences in the curing speed of the foamed material caused by uneven local temperatures. By providing a consistent thermal environment for the foamed material, the generation, expansion, and curing of bubbles during the foaming process are more uniform, forming a dense and stable foamed layer.

[0049] The heating assembly employs a combination of embedded electric heating tubes and a high-thermal-conductivity heat-conducting plate to achieve uniform heating of the upper chamber. Specifically, resistance heating tubes are evenly arranged in a grid pattern inside the upper mold, with uniform spacing, and fixed to the back of the heat-conducting plate using high-temperature resistant insulating material. The heat-conducting plate is made of aluminum alloy or copper, with a thickness controlled at 5-10mm, possessing excellent thermal conductivity. Its surface is smoothed and coated with a high-temperature resistant, anti-oxidation coating, directly contacting the upper chamber to transfer heat. To ensure the uniformity and precision of heating, PTC thermistor temperature sensors are embedded at multiple key locations on the heat-conducting plate, combined with a PID controller for real-time temperature monitoring and adjustment. This keeps the upper chamber within the suitable temperature range for the curing of the foamed material, ensuring both the quality and density of the foamed layer, while also improving processing efficiency and product performance.

[0050] The working method of this device is as follows:

[0051] S1. The upper mold is mounted on the side of the lower mold by the movable upper mold frame, and the lower box plate is placed horizontally on the lower mold table;

[0052] S2. The upper panel is hooked by the side hook unit and moves directly above the lower panel by moving the upper mold frame. The horizontal movement direction is parallel to the side of the rectangular lower panel.

[0053] S3. The foam material outlet of the foam material generation assembly supplies foam material to the upper surface of the lower compartment panel during the process from entering the area above the lower compartment panel to leaving the area above the lower compartment panel.

[0054] S4. After the upper panel moves to be directly above the lower panel and aligned, the side hook unit hooks down the upper panel, and the hydraulic cylinder drives the lower mold to descend, causing the upper panel to press onto the foam material on the upper surface of the lower panel.

[0055] S5. The side hook unit works, and the upper panel, foam material and lower panel are locked and pressed together by the side hook unit and the hook part of the lower mold.

[0056] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
