Description

Technical Field

[0001] This utility model relates to the field of particleboard production, specifically to a device for uniform hot pressing and forming of multi-layer particleboard. Background Technology

[0002] In the field of particleboard production and processing, hot pressing is a core step that determines product quality and production efficiency. Currently, multi-layer hot presses are commonly used in the industry for mass production. However, after hot pressing, existing multi-layer hot pressing equipment leaves a large amount of residual heat in the particleboard. Current equipment typically exposes the hot board to air for natural cooling, resulting in complete heat loss and no possibility of recycling. Furthermore, the cold particleboard entering the hot press requires additional energy to heat it from room temperature to the required hot pressing temperature, leading to double energy waste and contradicting current industry trends towards green production. Therefore, those skilled in the art have provided a multi-layer particleboard uniform hot pressing device to solve the problems mentioned in the background. Utility Model Content

[0012] The working principle of this utility model is as follows: Multiple particleboards to be hot-pressed are stacked in the storage frame 13. Then, the cover plate 15 is closed. The operator stands on the lifting plate 12. The dual-axis motor 32 drives the threaded rod 30 to rotate through the meshing of the bevel gear 4 33 and bevel gear 31. The threaded rod 30 drives the grid plate 35 to rise intermittently through the slider 34, so that the uppermost particleboard moves to the position of the discharge port 14. Then, the servo motor 20 drives the threaded shaft 19 to rotate. The threaded shaft 19 drives the push rod 23 to move through the threaded sleeve 21 and the extension rod 22. Push the topmost particleboard out of the discharge port 14, and the staff will then assist in pushing the particleboard to move it into the multi-layer hot press plate 2. Then, the dual-shaft motor 32 continues to work, driving the particleboard to continue to rise intermittently for a distance. At the same time, the dual-shaft motor 9 drives the threaded rod 7 to rotate through the meshing of the bevel gear 10 and the bevel gear 8. The threaded rod 7 drives the lifting plate 12 to rise intermittently for a distance through the lifting block 11. Then, move another particleboard into the multi-layer hot press plate 2 in the same way. Install multiple particleboards into the multi-layer hot press plate 2 in the same way. The hydraulic mechanism 3 drives the multi-layer hot press plate 2 to press the particleboard, so that the particleboard is hot-pressed into shape. Then, the workers take the hot-pressed particleboard out of the multi-layer hot press plate 2, stack it in the temporary storage frame 26, and cover it with the cover plate 27. Then, the particleboard in the storage frame 13 is put into the multi-layer hot press plate 2 to continue the work. Meanwhile, the exhaust fan 36 removes the residual heat inside the particleboard in the temporary storage frame 26 through the left connecting pipe 37, hollow rod 38, and through hole 28, and transfers the heat to the storage frame 13 through the right connecting pipe 37, hollow rod 38, and through hole 16 to preheat the particleboard inside the storage frame 13. This effectively utilizes the residual heat of the particleboard to preheat the particleboard to be hot-pressed, avoiding heat waste and improving the hot-pressing efficiency of the particleboard. When the temporary storage frame 26 is full of particleboard and all the heat has been removed, the dual-axis motor 32 is controlled to drive the grid plate 35 to rise, lifting the particleboard out of the temporary storage frame 26 for easy collection and processing.
