Description
Technical Field
The invention belongs to the field of wood processing, and particularly relates to a high-frequency glue-free compacting device.
Background
Compressed wood has long been available and is not a new term for the wood processing arts. In the united states at the beginning of the 20 th century, sears and Olsen have already held patents for the production of compressed wood. That is, laminated wood and compressed wood are also commercially produced in germany, but these products are all called "lignofenol". Many studies and scholars, such as Bernhard, perry and Stern, have conducted many experiments on the mechanical properties of laminated wood and compressed wood. The glued laminated wood (compregnated wood) is also commercially produced in the united states and germany, and is called "pregwood" in the united states and "Kunstharzschichtholz (KHS)" in germany. The method is used for increasingly reducing and limiting the quantity of the precious tree species wood at home and abroad, and with the development of the existing wood strengthening technology, low-density wood with lower cost is adopted in more and more occasions, and is compressed into a high-density board with better mechanical property, so that the application range of the wood is enlarged. However, since the plant cell wall has low plasticity, it is not easy to directly compress the plant, and the wood is broken by explosion, it is generally necessary to heat the wood before compressing the plant cell wall to soften the wood.
Chinese patent CN104400863a discloses an apparatus for compacting cork into hard wood, which uses a hot platen to heat and pressurize the cork, thereby achieving the purpose of improving the quality, strength and bearing strength of the wood. However, the traditional wood heating and pressurizing mode adopts a contact heating mode by using heat conducting oil or steam, the heating period is long, the temperature inside the wood is uneven, the production efficiency is low, and the density inside the compressed wood is uneven, so that the subsequent processing and use of the wood are affected; and because the medium contact type heating is adopted, a large amount of heat conduction oil or steam exists on the surface of the compressed wood, even in a shallow layer, more steps are needed to process the compressed wood before processing, and the processing cost of the wood is further increased.
