Bamboo vertical and horizontal flattening process

Abstract

The invention discloses a bamboo vertical and horizontal flattening process. The process has the following steps of: S01, cutting off a bamboo tube, removing the inner joint, removing the outer jointand removing the bamboo green sequentially; S02, vertically slitting the bamboo tube processed by S01 and performing high temperature softening treatment; S03, vertically pre-flattening the bamboo tube after high temperature softening treatment in S02; S04, horizontally flattening the vertically flattened bamboo tube in S03; and S05, performing double-sided planning, pressurized positioning, stacking and drying on the horizontally flattened bamboo tube in S04. The bamboo vertical and horizontal flattening process utilizes the respective advantages of vertical flattening and horizontal flattening, cooperates with relevant softening treatment process to realize multi-level flattening of the bamboo tube, and solves the problems of operation danger, low material rate, poor effect and low efficiency and the like of an original production process.

Description

technical field [0001] The invention relates to a technical method for vertically and horizontally flattening bamboo, and belongs to the technical field of moso bamboo flattening. Background technique [0002] China is a big country of bamboo planting and bamboo industry. Bamboo products are closely related to people's life, and they penetrate into all aspects of people's basic necessities of life. However, the natural thin-walled and hollow structure of bamboo, with bamboo green on the outer surface, and bamboo septum and bamboo yellow inside, all these characteristics have brought difficulties to the processing of bamboo. At present, in the process of producing moso bamboo cutting boards, ordinary bamboo flooring, bamboo laminated wood and other products, in order to improve the surface aesthetics of the products, reduce the loss of split bamboo, reduce the cutting amount of the inner and outer surfaces of moso bamboo, and improve the utilization rate and production effici...

AI Technical Summary

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
