Method for manufacturing bamboo-flattened slab

Abstract

The invention discloses a method for manufacturing a bamboo-flattened slab. The method comprises the following steps that (1) the inner skin of bamboo is removed, and the inner skin layer of the wholebamboo section is planed by using a rotary-cut method; (2) the bamboo section is softened with water steam for temperature rise and pressure rise, the admission steam pressure is 1.35 MPa, the temperature is 180 DEG C, and the softening time is 5-7 minutes; (3) a bamboo fresh layer is free from damage gashes, and a conical pointed bulge of a pushing roller surface or a nicking tool is changed into an arc bulge with a curvature radius of n or a right trapezoid bulge with an upper bottom of n, a height of n and a lower bottom of 2n; (4) thickness defining, inner skin removing and planing are conducted, a blank plate is flattened and then subjected to thickness measuring by a thickness defining, inner skin removing and planing machine, and microcomputer programming is carried out for automatic planing; and (5) drying and carbonization are conducted, two inner skin surfaces are longitudinally and oppositely folded, and small square rods are clamped at two longitudinal ends of the top surface of one bamboo green separately to form a stacking unit to be put in a drying and disinfecting carbon dryer for drying and carbonization.

Description

technical field [0001] The invention relates to a processing method of bamboo, in particular to a production method of bamboo flat boards. Background technique [0002] Bamboo flattening technology has been used in the earlier bamboo silk production and reorganized bamboo production. The flattening process is used as the previous process of bamboo silk production or reorganized bamboo production. The cracks in the unfolded bamboo slices are large and dense, which is suitable for bamboo Silk and recombinant bamboo production needs. With the development of replacing wood with bamboo and the deepening and widening of bamboo utilization, the development and utilization of bamboo flat panels have emerged in recent years. Therefore, many devices and methods for the production of this product have been published in patent materials. As CN202910953 discloses a "high temperature softening tank for moso bamboo", CN202716349 announces "a kind of original bamboo flattener" that the app...

With the development of replacing wood with bamboo and the deepening and widening of bamboo utilization, the development and utilization of bamboo flat panels have emerged in recent years. Therefore, many devices and methods for the production of this product have been published in patent materials. As CN202910953 discloses a "high temperature softening tank for moso bamboo", CN202716349 announces "a kind of original bamboo flattener" that the applicant carries out longitudinal flattening of moso bamboo, and the "round bamboo flattener" of CN201483606 also adopts longitudinal flattening In this way, dense line marks are engraved on the inner wall of the bamboo by the engraving knife on the engraving roll. CN202528289 announced that although the "moso bamboo flattening device" is horizontally advanced into the bamboo section, the roller surface of the lower pressing roller is covered with cones. The shape is pointed and convex. During the rolling process of flattening, the inner wall of the bamboo is punctured with small holes about 5mm deep.
