Description

Technical Field

[0001] This utility model relates to the field of cold storage panel processing technology, and in particular to a multi-layer cold storage panel filling structure. Background Technology

[0002] In the current cold storage panel manufacturing industry, it is common practice to add functional materials between specific layers of the panel to improve its overall performance. For example, in the production of some polyurethane cold storage panels, heat insulation boards or flame-retardant insulation boards are added between the polyurethane sandwich layer and the color steel plate. Phenolic cold storage panels, with phenolic foam as the core material, have advantages such as being lightweight, non-toxic, non-corrosive, heat-insulating, energy-saving, and sound-insulating. When combined with protective materials such as color steel plates, they can significantly improve the fire resistance and heat insulation performance of the cold storage panel.

[0003] The traditional injection method involves placing pre-treated panels in a mold and then injecting functional materials into specific interlayer spaces using specialized injection equipment. For example, when using a polyurethane foaming machine, the mixed polyurethane raw material is piped into the interlayer spaces within the mold. The material foams and expands within the mold, filling the interlayer spaces to form an insulation layer. During the injection of functional materials, a hydraulic system or other pressing device is used to press the panels within the mold, ensuring a tight bond between the panels and the functional materials. For instance, when pressing polyurethane cold storage panels, upper and lower pressure plates apply pressure to ensure a close fit between the polyurethane foam and the metal panel.

[0004] However, currently, most manufacturers use polyurethane foaming machines to add insulation material to individual cold storage panels one by one. This requires placing pre-treated panels sequentially into a mold, and then transporting the mixed polyurethane raw material through pipes to the interlayer spaces within the mold. The material foams and expands, filling the interlayer spaces to form an insulation layer. Subsequently, a hydraulic system drives the upper and lower pressure molds to press the polyurethane foam tightly against the metal panel. This method is difficult to use for adding insulation to multiple cold storage panels. Therefore, a multi-layer cold storage panel filling structure needs to be designed.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0006] This utility model provides a multi-layer cold storage panel filling structure to solve the problem that most companies currently use polyurethane foaming machines to fill insulation material into individual cold storage panels one by one and press them together, making it difficult to fill multiple cold storage panels.

[0007] The present invention adopts the following technical solution: a multi-layer cold storage panel filling structure. It mainly includes a processing table; a support mechanism mounted on the processing table, the support mechanism including a placement part one and a placement part two disposed on the processing table for placing two sets of cold storage panels; a support part for supporting the placement part two is provided on the placement part one; the support part includes a frame mounted on the placement part one, with limiting blocks on both sides of the frame, and a fixing rod passing through the limiting blocks; the placement part two is fitted onto the frame; a pressing part for pressing the upper panel on the placement part one is movably mounted on the fixing rod; the pressing part includes a pressure plate one movably sleeved on the fixing rod through a protrusion; a spring is sleeved on the fixing rod, and the two ends of the spring are respectively connected to the placement part one and the protrusion.

[0008] The processing table is equipped with a pressing component that simultaneously presses the upper panels on the two sets of placement parts.

[0009] Furthermore, the placement part one includes a base plate one disposed on the processing table. Four sets of side templates suitable for assembling into a square structure are installed on the base plate one. Multiple sets of limiting blocks are installed on the base plate one. The limiting blocks are tightly fitted with the side templates. An overlap groove is provided at the right angle position of the side templates. The placement part two has a similar structure to the placement part one. The base plate one of the placement part two is defined as the base plate two.

[0011] Furthermore, the diameter of the pressure rod is larger than the diameter of the contact portion, and the end of the pressure rod has an inner groove that matches the diameter of the contact portion.

[0012] Furthermore, the number of placement parts of the support mechanism can be flexibly adjusted according to actual production needs.

[0013] Furthermore, a filling assembly is installed on the processing table. The filling assembly includes a mounting frame installed on the processing table.

[0016] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0017] A multi-layer cold storage panel filling structure features a double-layer modular design with a support mechanism. By stacking two placement sections (section 1 and section 2) via a frame and fixing rod, two sets of cold storage panels can be placed simultaneously, significantly reducing clamping time compared to traditional one-by-one operations. The spring in the holding section, in conjunction with the fixing rod, provides adjustable initial support for the first pressure plate. When the second pressure plate is pressed down by a cylinder, the nested structure of the pressure rod and the contact section simultaneously drives the first pressure plate to press the two sets of panels together, avoiding the cumbersome sequential pressing of traditional hydraulic systems. This upgrades single-batch processing from traditional one-by-one operations to simultaneous processing of two sets. Attached Figure Description

[0027] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0028] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0029] Reference Figures 1-4 As shown, this utility model embodiment provides a multi-layer cold storage panel filling structure, including a moving component 1. The moving component 1 includes a processing table 11, and a support mechanism 2 is provided on the processing table 11. The support mechanism 2 is used to support the upper and lower panels of multiple sets of cold storage panels. The support mechanism 2 includes a placement part 21 provided on the processing table 11. The placement part 21 includes a base plate 211 provided on the processing table 11. The base plate 211 is suitable for placing the lower panel, and four sets of side templates 213 suitable for assembling into a square structure are bolted to the base plate 211. The space enclosed by the four sets of side templates 213 is suitable for restricting the lower panel.

[0030] Multiple sets of limiting blocks 212 are installed on the base plate 211 using fasteners (such as high-strength screws). These limiting blocks 212 fit tightly with the side templates 213, restricting the position of the four sets of combined side templates 213 from multiple directions. This prevents the side templates 213 from shifting during cold storage panel processing, ensuring structural stability. Furthermore, the shape of the limiting blocks 212 matches the edge contour of the side templates 213, and their surfaces are equipped with rubber anti-slip pads to further enhance the limiting effect. At the right-angle positions of the side templates 213, overlapping grooves 214 are provided. When the four sets of side templates 213 are assembled, these overlapping grooves 214 cooperate to form a placement space adapted to the size of the upper panel. In the initial state, an initial gap is formed between the upper and lower panels. The size of this gap can be flexibly adjusted according to the type and amount of filling material needed, allowing for flexible adjustment of the width of the side templates 213 to provide space for the filling material.

[0031] Furthermore, a second placement part 22 is provided at the upper end of the first placement part 21. The second placement part 22 has a similar structure to the first placement part 21. Here, the base plate 211 of the second placement part 22 is defined as the second base plate. A support part is installed on the base plate 211. The support part is used to support the second placement part 22 to maintain a gap between it and the first placement part 21. The support part includes a frame 24 installed on the base plate 211 by fasteners. The frame 24 has at least two sets of limiting blocks 241 on both sides. At the same time, a fixing rod 242 is fixed through the limiting blocks 241. The second base plate of the second placement part 22 is fitted and installed on the frame 24.

[0032] Furthermore, a pressing part for pressing the upper panel placed on the placement part 21 is movably installed on the four sets of fixing rods 242. The pressing part includes a pressure plate 23 movably sleeved on the fixing rods 242 through a protrusion 243. A spring 244 is sleeved on the fixing rods 242. The two ends of the spring 244 are respectively connected to the bottom plate 211 and the protrusion 243 to provide initial support for the pressure plate 23, so that there is an adjustable initial gap between the pressure plate 23 and the bottom plate 211.

[0033] In order to simultaneously and tightly press the upper panels on both sets of placement parts, such as Figure 3 and Figures 4-5As shown, a pressing assembly 3 is installed on the processing table 11. The pressing assembly 3 includes a top frame 31 fixedly installed on the processing table 11, and four sets of guide rods 32 are fixedly installed through the top frame 31. A second pressure plate 34 is slidably installed on the guide rods 32. The second pressure plate 34 can slide smoothly on it to press and fasten the upper panel placed on the second placement part 22. At the same time, a cylinder 33 is fixedly installed on the top frame 31. The telescopic end of the cylinder 33 passes through the top frame 31 and is connected to the second pressure plate 34. Two sets of pressure rods 35 are fixedly installed on the bottom surface of the second pressure plate 34 to push the first pressure plate 23 down to press and fasten the upper panel placed on the first placement part 21. At the same time, a contact part 25 suitable for contacting the pressure rods 35 is fixedly installed on the protrusion 243.

[0034] It should be noted that the diameter of the pressure rod 35 is larger than the diameter of the contact part 25, and an inner groove adapted to the diameter of the contact part 25 is provided at the end of the pressure rod 35 (not shown in the figure).

[0035] When the piston rod of cylinder 33 extends, it pushes pressure plate 34 to move downward along guide rod 32. Pressure plate 34 first contacts the upper panel on placement part 22 and applies pressure. At the same time, the inner groove at the end of pressure rod 35 is precisely nested with contact part 25, and through mechanical linkage, pressure plate 23 moves downward synchronously, thereby pressing the upper panel on placement part 21.

[0036] In this application, the number of placement sections of the support mechanism 2 can be flexibly adjusted according to actual production needs to achieve synchronous filling of multi-layer cold storage panels. The support mechanism 2 adopts a layered stacking structure, with each placement section 1 21 and its associated placement section 22 constituting an independent processing unit. The units are connected by support sections (frame 24, fixing rods 242, etc.) to form a stable multi-layer structure.

[0037] Meanwhile, the length of the pressure rod 35 of the holding assembly 3 can be adjusted according to the number of expanded layers, ensuring that the pressure plate 23 on each layer can reliably link with the pressure rod 35 through the contact part 25. The stroke and thrust of the cylinder 33 can be adjusted by the control system to adapt to the load requirements of different layers.

[0038] It should be noted that the reference Figure 2 The processing table 11 is divided into an installation area on the right and a filling area on the left. In the initial state, the support mechanism 2 is located in the installation area.

[0039] In order to move the support mechanism 2 to the position of the filling area, while simultaneously being directly below the pressure holding component 3, as follows: Figures 1-2As shown, a movable module 12 is embedded in the processing table 11. The movable module 12 is a screw drive structure and includes a concave frame 121 embedded in the surface of the processing table 11. A screw 122 is horizontally bearing on the concave frame 121. A sliding seat (not shown in the figure) is threadedly connected to the screw 122. Guide rods 123 are fixedly installed on the concave frame 121 at both sides of the screw 122. The sliding seat is movably sleeved on the guide rod 123. The sliding seat is adapted to move along the straight direction of the guide rod 123 as the screw 122 rotates to be in the installation area / filling area. The base plate 211 of the placement part 21 is fixedly installed on the sliding seat by fasteners.

[0040] A motor 124 is fixedly mounted at one end of the concave frame 121. The output end of the motor 124 is connected to the lead screw 122 via a coupling. When the drive motor 124 drives the lead screw 122 to rotate, due to the threaded engagement between the sliding seat 1 and the lead screw 122, the sliding seat 1 will move linearly along the axial direction of the lead screw 122. At the same time, the guide rod 123 restricts the rotational freedom of the sliding seat 1, allowing it to move only along the direction of the guide rod 123. By controlling the forward and reverse rotation and the rotation angle of the motor 124, the direction and position of movement of the sliding seat 1 can be controlled, thereby accurately moving the support mechanism 2 to the installation area or the filling area.

[0041] It should be noted that in actual use, a filling hole communicating with the filling gap is usually opened on the side of a set of side templates 213;

[0042] In order to simultaneously fill two sets of fixed cold storage panels with filling material, such as Figures 3-5 As shown, a filling assembly 4 is installed on the processing table 11. The filling assembly 4 includes a mounting bracket 42 fixedly installed on the processing table 11. A second movable module 43 is installed on the mounting bracket 42 and is arranged parallel to the processing table 11. The second movable module 43 has a similar structure to the first movable module 12. Here, the first sliding seat of the second movable module 43 is defined as the second sliding seat. At the same time, a third movable module 44 is installed on the second sliding seat, which is perpendicular to the second movable module 43. The third movable module 44 has a similar structure to the first movable module 12. Here, the first sliding seat of the third movable module 44 is defined as the third sliding seat.

[0043] Furthermore, a filling unit is installed on the sliding seat three. This unit includes injection section one 46 and injection section two 48, both integrated and mounted on the sliding seat three, forming a dual-station filling structure. The two injection sections are fixedly installed via pipe clamps 45 and rigidly connected via a connecting frame 47, ensuring relative positional stability during movement. The pipe clamps 45 employ a quick-release structure for easy disassembly and maintenance of the injection sections. The connecting frame 47 is designed with adjustable positioning pins and fastening bolts, allowing adjustment of the distance between the two injection sections to accommodate different specifications of cold storage panels.

[0044] A storage cylinder 41 is installed on one side of the processing table 11, containing insulation material for filling. The storage cylinder 41 is connected to a high-pressure pump body through a pipe. The pump body can adjust the discharge pressure and flow rate according to the filling requirements. The discharge end of the pump body is connected to injection section one 46 and injection section two 48 respectively through high-pressure resistant hoses. The hoses adopt a corrugated design to ensure the sealing of material transportation while adapting to the movement requirements of the filling unit. Each injection section port is equipped with a shut-off valve, which can be quickly opened and closed through a pneumatic or electric control system to ensure precise control of the material filling process and avoid material leakage and waste.

[0045] After the support mechanism 2 positions the cold storage panel in the filling area, the second moving module 43 and the third moving module 44 work together: First, the second moving module 43 drives the filling unit to move laterally, aligning the injection section with the filling hole on the side template 213; then, the third moving module 44 pushes the filling unit forward, ensuring a tight connection between the injection port and the filling hole. The pump is started and the valve is opened, and the filling material in the storage cylinder 41 is delivered to the injection section through the hose, simultaneously filling the gap between the two sets of cold storage panels. After filling is complete, the valve is closed, and the filling unit resets under the drive of the moving modules, ready for the next operation.

[0046] In this application, photoelectric sensors, proximity sensors, etc., can be installed near the injection section 46 or the filling hole. When the injection section 46 approaches the filling hole, the sensor detects a signal and feeds it back to the control system. The control system then fine-tunes the movement of the moving module based on the feedback information to achieve precise alignment between the injection section 46 and the filling hole, further improving the accuracy and reliability of the alignment. A PLC control system is installed on the worktable processing table 11 to coordinate and control the various components.

[0047] Working principle: First, the operator places the lower panel of the cold storage panel on the base plate 211 of the placement section 21 in the installation area of ​​the processing table 11. It is then secured by four sets of side templates 213, and the side templates 213 are stabilized using limiting blocks 212. The upper panel is placed in the overlapping groove 214 of the side templates 213, forming a pre-set filling gap with the lower panel. If multiple layers of cold storage panels need to be processed, multiple placement section units can be stacked, and interlayer connections are achieved through the frame 24 and fixing rods 242.

[0048] Subsequently, the motor 124 of the moving module 12 drives the lead screw 122 to rotate, causing the sliding seat 1 to move the support mechanism 2 to the filling area along the guide rod 123, so that the cold storage panel is directly below the pressing assembly 3. At this time, the cylinder 33 pushes the pressure plate 2 34 down, and the pressure plate 2 34 first presses the upper panel on the placement part 22, while the pressure rod 35 and the contact part 25 are nested and linked, driving the pressure plate 1 23 down, realizing the synchronous and tight pressing of the two layers of cold storage panels.

[0049] During the material filling stage, mobile module 2 (43) and mobile module 3 (44) work together, adjusting the position of the filling unit based on sensor feedback and PLC control system commands. This aligns injection section 1 (46) and injection section 2 (48) with the filling holes on the side template 213. The insulation material in the storage cylinder 41 is pumped through the hose to the injection section. The PLC control system regulates the pump flow rate, pressure, and valve opening and closing according to set parameters to ensure the material is evenly injected into the gaps between the cold storage panels. After filling is complete, the valves close, the filling unit resets, and the support mechanism 2 moves back to the installation area to prepare for the next round of cold storage panel assembly and filling operations.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
