Description

Technical Field

[0001] This utility model belongs to the technical field of bamboo and wood product deep processing equipment, specifically relating to a bidirectional pressure device for gradient densification of bamboo and wood boards. Background Technology

[0002] Bamboo and wood board processing typically uses bamboo, wood, or bamboo-wood composite materials as raw materials. After material selection, drying to remove moisture and impurities, the materials are cut and combed into standard sizes. After gluing, they are assembled according to a pre-set structure, then sent into a pressurizing device to apply pressure and heat up for curing. Finally, the finished product is formed after edge trimming, sanding, and anti-corrosion treatment.

[0003] CN206926042U discloses a hot pressing device for bamboo-wood composite panels, including a thickness measuring instrument, a heating boiler, and a hydraulic cylinder. A self-heating steel roller is positioned above the thickness measuring instrument. An oil storage tank is located on one side of the heating boiler, and a first hot oil transmission pipe is located on the same side. A second hot oil transmission pipe is fixedly installed on one side of the heat exchanger. A thickness adjustment cylinder is located below the hydraulic cylinder. An oil discharge pipe is located on one side of the upper pressure plate, and a lower pressure plate is fixedly installed below it. This hot pressing device for bamboo-wood composite panels, with its self-heating steel roller, heat exchanger, and thickness measuring instrument, can be heated by both hot oil and itself, reducing the risk of poor hot pressing due to insufficient oil temperature. It also enables heat recycling, making it more energy-efficient and environmentally friendly. Furthermore, it allows for timely monitoring of the panel thickness after hot pressing, making it suitable for various working conditions and offering better application prospects.

[0004] In summary, existing pressing equipment is mainly unidirectional press, which mostly uses hydraulic or mechanical drive to compact the board by applying force on one side. However, this can easily lead to uneven density in the thickness direction of the bamboo template and edge warping. Although some bidirectional pressing equipment can achieve simultaneous force application from top to bottom and improve the uniformity of pressing, it is difficult to form a gradient structure of wear-resistant surface and tough core layer in the board because the pressure of the pressing plate is constant during pressing. This results in problems such as single densification effect, brittleness due to excessive pressing, and low yield of processed products. Utility Model Content
