[0028] The preferred embodiments of the present application will be described in detail below with reference to the accompanying drawings, wherein the drawings form a part of the present application and are used to explain the principles of the present application together with the embodiments of the present application, but are not used to limit the scope of the present application.

[0029] The wood base plate hot pressing device in the present embodiment relates to the technical field of plywood hot pressing, and the shear telescopic unit can push out the wood base plate while being opened, realizes automatic ejection of the wood base plate, and improves production efficiency.

[0030] Please refer to Figures 1 to 5 The wood base plate hot pressing device in the present embodiment comprises a hot pressing assembly 100, a plurality of shear telescopic assemblies 200 and a plate ejection assembly 300, the hot pressing assembly 100 comprises a plurality of hot pressing plate bodies 110 capable of heating, the adjacent hot pressing plate bodies 110 are arranged at intervals to form a space for arranging the wood base plate, and the two hot pressing plate bodies 110 can simultaneously heat the wood base plate located between the two hot pressing plate bodies 110 to complete hot pressing and shaping of the wood base plate.

[0031] The scissor-type expansion and contraction assembly 200 is positioned between two adjacent hot-pressing platens 110. It comprises two sets of scissor-type lifting units 210 symmetrically positioned on either side of the hot-pressing platens 110. These two sets of lifting units can support the two hot-pressing platens 110, expanding or contracting the space between the adjacent hot-pressing platens 110. The scissor-type lifting units 210 include centrally hinged drive rods 211. One drive rod 211 is rotatably connected to the hot-pressing platen 110, while the other drive rod 211 is slidably connected to the hot-pressing platen 110 and can move along the hot-pressing platen 110. The two drive rods 211 rotate relative to each other under the action of an external force, driving the two hot-pressing platens 110 to move relative to each other, thereby compressing and loosening the wood-based panel.

[0032] The plate withdrawal assembly 300 includes an ejector 310, which is connected to the other end of the driving rod 211. The movement of the driving rod 211 expands the distance between the two hot pressing plate bodies 110. At the same time, the ejector 310 utilizes the moving thrust of the driving rod 211 to smoothly push the hot-pressed wood-based material board out of the hot press, making the board pushing process more automated and efficient.

[0033] In some embodiments, see 1 to Figure 3 The retracting plate assembly 300 also includes a driven rod 320, the two ends of which are respectively connected to the two scissor-type lifting units 210, and the end of the driven rod 320 is connected to the end of another driving rod 211. The setting of the driven rod 320 enables the scissor-type lifting units 210 on both sides to move synchronously.

[0034] During the specific implementation process, the driven rod 320 passes through the hot pressing plate body 110 and is connected to the driving rod 211 on both sides. The driven rod 320 will transmit the movement to the driving rod 211 on the other side, ensuring that the scissor-type lifting units 210 on both sides move synchronously, ensuring that the wood-based material board is evenly stressed during the pushing process, avoiding tilting or jamming of the board due to pushing one side too fast or too slow, and significantly improving the stability and smoothness of the pushing process.

[0035] In some embodiments, see Figure 3 The hot press body 110 includes a heating plate 111 and a support plate 112. The two heating plates 111 are spaced apart, and the two support plates 112 are symmetrically arranged on either side of the heating plate 111. The ends of the support plates 112 are fixedly connected to the two heating plates 111. The heating plates 111 and the support plates 112 are fixedly connected to the two heating plates 111 to form a rectangular structure, which significantly enhances the overall rigidity and stability of the hot press body 110. The rectangular structure can resist deformation under external forces, allowing the hot press body 110 to remain flat during operation and not easily bend or twist, thereby ensuring the stability of the hot pressing quality.

[0036] In some embodiments, see Figure 1and Figure 3 The support plate 112 is provided with a chute 112a adapted for the driven rod 320. The chute 112a is arranged along the direction of movement of the wood-based panel, providing precise guidance for the driven rod 320. The chute 112a is arranged along the direction of movement of the wood-based panel. The sliding of the driven rod 320 within the chute 112a ensures a stable, straight trajectory during the ejection process, preventing the panel from deflecting or getting stuck, and improving the smoothness and precision of the ejection process.

[0037] The slide groove 112a is adapted to the driven rod 320, so that the driven rod 320 can maintain a stable force path when pushing the wood-based material board, effectively reducing the shaking or deviation caused by the driven rod 320 during the pushing process, thereby ensuring the stability of the board during the pushing process and avoiding damage to the edge of the board or scratches on the surface.

[0038] In some embodiments, please refer to Figure 3 A guide groove 111a is provided on the heating plate 111. One end of the ejector 310 is slidably inserted into the guide groove 111a. The other end of the ejector 310 is connected to the driven rod 320. The guide groove 111a provides a fixed movement path for the ejector 310, ensuring that the ejector 310 moves along a predetermined straight line direction when pushing the wood-based panel, avoiding the ejector 310 from deflecting or tilting during movement, thereby ensuring the smooth ejection of the wood-based panel.

[0039] In some embodiments, see Figure 5 The heating plate 111 is provided with a heating core 111b, which is embedded in the heating plate 111, thereby ensuring the uniformity of the surface temperature of the entire heating plate 111, so that the wood substrate board is subjected to a uniform temperature during hot pressing, thereby avoiding local overheating or underheating, helping to improve the quality of the plywood, reduce internal stress, and reduce the risk of board deformation or delamination due to uneven heat.

[0040] The heating core 111b is equipped with a temperature sensor and a control system, so that the temperature of the heating plate 111 can be accurately controlled, which helps to adjust the temperature under different hot pressing conditions to adapt to different types of wood or adhesives and ensure the best hot pressing effect.

[0041] It should be noted that a heating wire is provided inside the heating core 111 b , and the heating wire can directly heat the heating plate 111 .

[0042] In some embodiments, see Figure 5A support sleeve 111c is provided within the heating plate 111. The support sleeve 111c is embedded within the heating plate 111, and the heating core 111b is inserted into the support sleeve 111c. The support sleeve 111c provides a fixed and stable mounting position for the heating core 111b, preventing displacement or loosening of the core during operation and improving the structural stability and durability of the entire heating plate 111.

[0043] The support sleeve 111 c tightly combines the heating core 111 b and the heating plate 111 , reducing the thermal resistance between the core and the heating plate 111 , so that heat energy can be more efficiently conducted from the heating core 111 b to the surface of the heating plate 111 .

[0044] It should be noted that the wood-based panel hot-pressing device also includes an oil press connected to the outermost hot-pressing platen 110. As an efficient power source, the oil press can provide powerful thrust or pull. By connecting the oil press to the outermost hot-pressing platen 110, it provides stable and powerful power to the scissor-type telescopic assembly 200, ensuring smooth and powerful movement when the scissor-type telescopic assembly 200 extends or contracts.

[0045] The hydraulic press is typically equipped with a sophisticated control system that can precisely adjust the output oil pressure and flow, thereby achieving precise control of the scissor-type telescopic assembly 200. By adjusting the parameters of the hydraulic press, the speed and force of the scissor-type telescopic assembly 200 can be flexibly controlled to meet the requirements of different process conditions.

[0046] Workflow: First, place the wood substrate boards that have been coated with adhesive in the gaps between the hot pressing plates in sequence. The spacing between each wood substrate board should be uniform to avoid excessive overlap or uneven stacking. Then, start the hydraulic press, which will drive the scissor-type telescopic assembly 200 to cause the hot pressing plate body 110 to begin to shrink and press the wood substrate boards tightly. Next, the heating plate 111 is evenly heated by the heating core 111b. During the hot pressing process, the control system should monitor the temperature and pressure in real time. Then, the hydraulic press drives the scissor-type telescopic assembly 200 to stretch, while the driven rod 320 drives the ejector 310 to move, pushing the hot-pressed wood substrate board out of the hot pressing device.

[0047] The above description is only a preferred specific implementation of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be covered by the present invention.
