Problems solved by technology

However, the single longitudinal flattening along the bamboo fiber direction of the prior art needs to be scored on the inner surface of the moso bamboo, and the bamboo board after the flattening has deep cracks, and the amount of cutting is large; The method of horizontal flattening perpendicular to the bamboo fiber direction is used for production, but this method needs to use a pressure roller to carve deeper grooves on the back of the bamboo to prevent cracking after flattening, and the bamboo tube is prefabricated after the softening process. It is very difficult to open, and workers need to use tools to pry open the opening of the moso bamboo, and then insert it into the horizontal flattening machine. mouth process, easy to crack the bamboo tube, and greatly reduce the production efficiency and increase the risk

specific Embodiment 1

[0024] A process method for vertical and horizontal flattening of bamboo, comprising the following steps:

[0025] Step 1: First cut the bamboo tube to the required length, then remove the inner knot, then remove the outer knot, and combine with the greening treatment. The de-blue treatment is realized by installing a limit ring on the shaft of the de-blue milling cutter and applying an air pressure of 0.3-0.7 MPa, preferably 0.3 MPa, and the de-blue thickness is 0.4-0.6 mm, preferably 0.4 mm.

[0026] Step 2, the bamboo tube treated in step 1 is longitudinally slit, and the longitudinal slit adopts circular saw blade sawing to carry out longitudinal slitting to the bamboo tube, and the width of the longitudinal slit is 1~3mm, preferably 1mm; then carry out high temperature softening treatment , the high temperature softening treatment is carried out in a closed pressurized tank, the heating and softening medium is saturated steam, the temperature is 160-180 ℃, preferably 160 ...

Abstract

The invention discloses a process method for flattening bamboo material vertically and horizontally. S01, the bamboo tube is cut, inner knots, outer knots and bamboo green are removed in sequence; S02, the bamboo tubes treated in S01 are longitudinally slit, and High temperature softening treatment; S03, carrying out longitudinal pre-flattening of the bamboo tube after high temperature softening in S02; S04, carrying out horizontally flattening the bamboo tube longitudinally pre-flattened in S03; S05, carrying out double-sided planing of the bamboo tube horizontally flattened in S04, Press-fixed and stack-dried. The invention provides a process method for vertical and horizontal flattening of bamboo materials, which utilizes the respective advantages of vertical flattening and horizontal flattening, and cooperates with relevant softening procedures to realize multi-level flattening of bamboo tubes, solve the operation danger of the original production process, and improve the production efficiency. The material rate is low, the effect is not good, and the efficiency is not high.

Description

technical field [0001] The invention relates to a process method for vertical and horizontal flattening of bamboo, and belongs to the technical field of bamboo flattening. Background technique [0002] China is a big country with bamboo planting and bamboo industry. Bamboo products are closely related to people's lives and penetrate into all aspects of people's necessities of life. However, the natural thin-walled hollow structure of bamboo, with bamboo green on the outer surface, and bamboo partition and bamboo yellow on the inside, all bring difficulties to the processing of bamboo. At this stage, in the production process of moso bamboo cutting boards, common bamboo floors, bamboo laminated wood and other products, in order to improve the surface aesthetics of the products, reduce the loss of cutting bamboo, reduce the amount of cutting on the inner and outer surfaces of moso bamboo, and improve the utilization rate and production efficiency of bamboo as a whole, The bam...
