[0002] In the field of building panel processing, hot presses are used to bond multi-layer panels by heating and pressurizing. However, traditional hot presses require manual unloading, and the freshly processed panels are very hot, posing a risk of burns to workers during handling. Furthermore, manual unloading is slow, making it difficult to keep up with production pace, and uneven force during handling can cause panels to collide and fall, resulting in edge damage, increased product scrap rates, and further increased production costs. Therefore, this utility model is proposed. Utility Model Content

[0008] Furthermore, the receiving unit includes an inclined conveyor belt mechanism, and a receiving box is provided on one side of the conveyor belt mechanism.

[0009] Furthermore, the mounting frame of the conveyor belt mechanism is provided with two support legs at both ends of its bottom.

[0029] Example 1

[0030] A hot press for processing building panels, such as Figure 1 , Figure 2 and Figure 3 As shown, it includes a working platform 1, on which a hydraulic mechanism 4, an upper pressure plate 5, a lower pressure plate 6, a material receiving unit, and a material pushing mechanism are provided.

[0031] Four support columns 2 are fixed on the working platform 1. A top plate 3 is fixed to the top of the four support columns 2. A hydraulic mechanism 4 is installed on the top of the top plate 3. The telescopic end of the hydraulic mechanism 4 passes through the top plate 3 and connects to the upper pressure plate 5. The four corners of the upper pressure plate 5 pass through the support columns 2 respectively. When the hydraulic mechanism 4 pushes the upper pressure plate 5 to move, the upper pressure plate 5 moves up and down along the support columns 2. A lower pressure plate 6 is set below the upper pressure plate 5. The size of the lower pressure plate 6 is smaller than that of the upper pressure plate 5. The lower pressure plate 6 is located inside the four support columns 2.

[0032] Two first lifting mechanisms 7 are hinged to the bottom of the left and right ends of the lower pressure plate 6, respectively. Figure 3As shown, the work platform 1 is provided with four first grooves 101, and four first lifting mechanisms 7 are respectively fixedly installed in the first grooves 101. When the sheet is hot-pressed, the bottom of the lower pressure plate 6 is tightly fitted with the work platform 1; after the hot-pressing process is completed, by adjusting the extension and retraction stroke of the first lifting mechanisms 7 at both ends of the lower pressure plate 6, the lower pressure plate 6 is tilted, and the sheet slides down along the tilted lower pressure plate 6 under the action of gravity.

[0033] A receiving unit is provided at one end of the working platform 1. The receiving unit includes an inclined conveyor belt mechanism 13, which is inclined downwards. A receiving box 16 is provided on one side of the conveyor belt mechanism 13. Two support legs 14 are provided at each end of the bottom of the mounting frame of the conveyor belt mechanism 13. Guide rods 15 are provided on the side walls of the two support legs 14 furthest from the working platform 1. Guide grooves 1601 are provided on the two opposite side walls of the receiving box 16. Figure 5 As shown, one end of the guide groove 1601 is an open end, and the guide rod 15 is slidably connected to the guide groove 1601.

[0034] The support leg 14 can be a telescopic rod, which facilitates adjustment of the height or tilt angle of the conveyor belt mechanism 13 according to actual production needs. When a telescopic rod is used, the guide rod 15 needs to be installed on the fixed part of the telescopic rod. Universal wheels with locking mechanisms are installed at the four corners of the bottom of the receiving box 16 to facilitate the transfer of the receiving box 16. A rubber buffer layer can be provided on the inner wall of the receiving box 16 to reduce the collision between the sheet metal and the inner wall of the receiving box 16.

[0035] The downward-sloping conveyor belt mechanism 13 can receive the sheet material sliding out from the inclined lower pressure plate 6. The conveying force of the conveyor belt buffers the sliding inertia of the sheet material, preventing the sheet material from directly impacting the receiving box 16 and causing edge bumps and surface scratches. The tilt angle of the conveyor belt can be adjusted in conjunction with the tilt angle of the lower pressure plate 6, so that the entire transfer process of the sheet material from the lower pressure plate 6 to the conveyor belt and then to the receiving box 16 forms a smooth transition path.

[0036] The guide rod 15 on the support leg 14 slides in conjunction with the guide groove 1601 of the receiving box 16, which can precisely limit the installation position of the receiving box 16 and ensure that the receiving box 16 is always facing the discharge end of the conveyor belt, thus avoiding the plate falling or getting stuck due to the offset of the receiving box 16.

[0037] A pushing mechanism is provided at one end of the working platform 1 opposite to the receiving unit. The pushing mechanism includes a mounting plate 8, which is located to the left of the upper pressure plate 5. The mounting plate 8 is equipped with a support plate 801 and an electric push rod 9. The electric push rod 9 is fixedly connected to the support plate 801, and its telescopic end passes through the support plate 801 and connects to the push plate 10. Two second lifting mechanisms 11 are hinged to the bottom of the left and right ends of the mounting plate 8, respectively. The working platform 1 is provided with four second grooves 102, and the second lifting mechanisms 11 are installed in the second grooves 102. The push plate 10 is moved by the electric push rod 9, thereby pushing the plate on the lower pressure plate 6. At the same time, the position of the push plate 10 is adjusted by the second lifting mechanisms 11 in conjunction with the height or tilt angle of the lower pressure plate 6.

[0038] The core of the receiving unit relies on the inertia or gravity of the sheet material after it slides off the inclined lower pressure plate 6, and is received by the conveyor belt. When the inclination angle of the lower pressure plate 6 is small, the sheet material itself lacks sufficient sliding power, or the friction between the bottom surface of the sheet material and the surface of the lower pressure plate 6 is large, and it may remain stuck on the lower pressure plate 6. The pusher mechanism can provide a push force to the sheet material, allowing it to slide from the lower pressure plate 6 to the conveyor belt mechanism 13, providing additional push force to ensure that it smoothly enters the receiving unit.

[0039] Both the first lifting mechanism 7 and the second lifting mechanism 11 use electric telescopic rods. The top of the electric telescopic rod is rotatably connected to an inverted U-shaped block 12 via a rotating shaft. Figure 4 As shown, threaded holes 1201 are provided at the four corners of the top of the inverted U-shaped block 12, which are installed with bolts and mounting plate 8 or pressure plate 6.

[0040] It also includes a control box, which can be set on the work platform 1 or installed on one side of the work platform 1. The controller in the control box controls the start, stop and coordinated operation of the hydraulic mechanism 4, the first lifting mechanism 7, the second lifting mechanism 11 and the conveyor belt mechanism 13.

[0041] The method of using the hot press provided in this embodiment is as follows:

[0042] The sheet material to be processed is placed in the center of the lower pressure plate 6 by manual labor or a robotic arm. The hydraulic mechanism 4 is activated, driving the upper pressure plate 5 downward along the support column 2 until it is in contact with the sheet material. A preset pressure is applied, and the sheet material is heated by the heating components inside the upper and lower pressure plates 5 and 6. The pressure and temperature are maintained for a preset time to complete the hot pressing of the sheet material. After hot pressing, the hydraulic mechanism 4 drives the upper pressure plate 5 to rise and reset. The controller simultaneously activates the first lifting mechanism 7 of the lower pressure plate 6, causing the lower pressure plate 6 to tilt to the left. If the sheet material cannot slide on its own due to weight or friction, the pushing mechanism (the second lifting mechanism 11 adjusts the height and tilt angle of the pushing plate) is activated to push the sheet material along the tilted lower pressure plate 6 towards the conveyor belt mechanism 13 until the sheet material is completely detached from the lower pressure plate 6. Then, the electric push rod 9 retracts and resets. After the sheet material slides into the conveyor belt mechanism 13, it is transported to the receiving box 16.

[0043] Example 2

[0044] A hot press for processing building panels is disclosed in this embodiment. The technical solution is basically the same as that in Embodiment 1, except that the structure of the upper pressure plate 5 and the lower pressure plate 6 in this embodiment has been optimized. The upper pressure plate 5 and the lower pressure plate 6 have the same structure. The upper pressure plate 5 will be used as an example for detailed description below:

[0045] like Figure 6 As shown, the upper pressure plate 5 includes a housing 501. Inside the housing 501, near the heating surface, is a heat-conducting plate 502. Above the heat-conducting plate 502 is a heating component, and above the heating component is a heat-insulating plate 504. The heat-conducting plate 502, the heating component, and the heat-insulating plate 504 are all fixedly connected to the side wall of the housing 501. The order of the heat-conducting plate, heating component, and heat-insulating plate inside the housing of the lower pressure plate 6 is exactly the reverse of that of the upper pressure plate 5.

[0046] In this embodiment, the heating assembly includes two sets of oil guide pipes 503 arranged side by side along the width direction of the housing 501, such as... Figure 7 As shown, the oil guide pipe 503 is a serpentine pipe, with an oil inlet 5031 and an oil outlet 5032 at each end. The oil inlet 5031 and the oil outlet 5032 are fixedly connected to the side wall of the shell 501. The serpentine pipe's curved path can significantly extend the flow distance of the hot oil within the shell 501. Furthermore, the two sets of parallel distribution can cover the entire area of ​​the shell, ensuring uniform heating of all positions on the heat-conducting plate 502 compared to straight or single-set oil pipes.

[0047] Temperature sensors are installed at both the oil inlet 5031 and the oil outlet 5032. Temperature sensors are also installed on the two inner sidewalls along the length of the housing. These temperature sensors are connected to the controller. The temperature sensors at the oil inlet 5031 and the oil outlet 5032 provide real-time feedback on the temperature difference between the hot oil inlet and outlet, allowing for real-time temperature monitoring. This enables the controller to adjust the hot oil flow rate and heating power (such as the output of the heating source) based on the temperature difference, precisely controlling the heating process and ensuring that the temperature of the heating surface of the upper pressure plate 5 remains stable within the required process range.

[0048] The heat-conducting plate 502 has two parallel flow channels on its side wall near the heating component, such as... Figure 8 As shown, the guide channel includes multiple nested U-shaped grooves 5023, each with a different size, gradually decreasing in size from the outside to the inside. The four corners of the central U-shaped groove 5023 are respectively provided with connecting grooves 5024, which communicate with all the U-shaped grooves 5023. The sidewall of the heat-conducting plate 502 is provided with an inlet pipe 5021 and an outlet pipe 5022. The inlet pipe 5021 communicates with the central U-shaped groove 5023, and the outlet pipe 5022 communicates with the outermost U-shaped groove 5023.

[0049] The heat-conducting groove structure on the heat-conducting plate 502 is designed for the cooling process (or temperature regulation requirements) after hot pressing, and its advantages are:

[0050] Multiple U-shaped grooves 5023 of decreasing size are nested from the outside to the inside. With the flow-dividing effect of the connecting groove 5024, the cooling medium flows in from the center and is evenly distributed to each U-shaped groove 5023 through the connecting groove 5024. Finally, it flows out from the outermost U-shaped groove 5023 through the liquid outlet pipe 5022, forming an orderly flow path from the inside to the outside, reducing the flow resistance of the medium and ensuring that the cooling medium and the heat-conducting plate 502 are in full contact for heat exchange.

[0051] The heating component and the heat-conducting plate 502 are integrated in the same pressure plate. The continuous process of "heating-heat preservation-cooling" can be realized through the linkage of the control system (such as starting hot oil heating during hot pressing, and switching to cooling medium after the preset time is reached). There is no need to transfer the plate to a separate cooling device, which shortens the production flow time and improves the overall efficiency.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
