Problems solved by technology

There are still a series of problems in the current manufacturing method, which need to be improved: the bamboo chips required for sliced ​​thin bamboo squares are of high quality, and the utilization rate of bamboo materials is low; the preparation process of bamboo chip units is complicated, it is difficult to realize continuous production, and the production efficiency Low; there are many glued surfaces in the bamboo square manufacturing process, the amount of adhesive used is large, the manufacturing cost is high, and the environmental protection is poor; the glued surface is mostly hindered by moisture and heat conduction, which is not conducive to the humidification or softening of the bamboo square; in addition, the bamboo square lumber The adhesive layer is easily affected by environmental factors such as temperature and humidity, and thin bamboo products are prone to cracks or deformation due to environmental changes

example 1

[0028] Example 1, the production specification is 2100×250×0.4mm chordwise flattened and sliced ​​bamboo veneer, contrast figure 1 with figure 2 , The manufacturing method is as follows:

[0029] (1) Cut the bamboo with a moisture content of 25% into 2250mm long bamboo; through a device equipped with an inner milling cutter and an outer planer, the inner section, outer section, bamboo green and bamboo of the bamboo with an inner diameter of 90mm or more Remove the yellow at the same time, and use a circular saw to make a longitudinal straight seam along the bamboo axis.

[0030] (2) Fix the bamboo material 2 described in step (1) on the stainless steel backing plate 3 with a thickness of 4 mm, so that the straight slot of the bamboo material 2 faces upward. When the backing plate 3 is filled with the bamboo material 2, the backing plate 3 containing the bamboo material 2 is pushed onto the pressure plate of the built-in compressor of the high-temperature steam pressure tank, and t...

[0044] Example 3, the production specification is 2100×500×0.8mm radially flattened and sliced ​​bamboo veneer, contrast image 3 , The manufacturing method is as follows:

[0045] (1) Cut the bamboo with a moisture content of 20% into 2300mm long bamboo; through a device equipped with an inner milling cutter and an outer planing knife, the inner section, outer section, bamboo green and bamboo of the bamboo with an inner diameter of 80mm or more The yellow is removed at the same time, and a longitudinal straight through seam is made along the axis of the bamboo.

[0046] (2) Fix the bamboo material 2 described in step (1) on the stainless steel backing plate 3 with a thickness of 3 mm, with the straight slit of the bamboo material 2 facing downward. Push the backing plate 3 containing the bamboo material 2 onto the pressure plate of the press in the high-temperature steam pressure tank, and close the pressure tank cover. Fill the tank with high-temperature steam at a temperature ...

Abstract

The invention discloses a production method for flattening and slicing a bamboo veneer. The method is characterized in that a bamboo material is softened through high-temperature steam; after the bamboo material is softened, the bamboo is pressurized and flattened by a horizontal pressing method, and thus a complete wide flattened bamboo board can be obtained; the flattened bamboo board is processed by fine slicing and sizing, glue applying, blank combining, manufacturing of bamboo blocks, softening and slicing to obtain the sliced bamboo veneer product. According to the method, the preparation process of a bamboo unit is simplified; the utilization rate of the bamboo material is increased; the quantity of adhesives is decreased, so that the environmental protection performance of the product is improved, and the production cost is decreased; adhesive layers in the bamboo blocks are decreased, and thus the water heat can be conveniently transferred, and the bamboo block softening timeis decreased, and as a result, the production efficiency is greatly improved.

Description

Technical field [0001] The invention belongs to the field of man-made board manufacturing, and specifically relates to a production method for flattening and cutting bamboo veneers. Background technique [0002] my country has always been at the forefront of the world in bamboo processing technology and product research and development. However, most bamboo products are still labor-intensive and resource-intensive products, with low technological content and serious homogeneity. Therefore, the conservation and high-value development and utilization of bamboo resources has become an inevitable development trend. In recent years, sliced ​​thin bamboo decoration materials have been successfully developed with bamboo slices as the unit. This product not only has the unique texture of bamboo with a light color, fresh and natural, but also has properties similar to precious hard broad-leaved materials and is suitable for veneer decoration materials. The development of sliced ​​thin ba...
