Bamboo chip defibering, and bamboo green and bamboo yellow removing pressing roll device and defibering machine

Abstract

The invention relates to a bamboo chip defibering, and bamboo green and bamboo yellow removing pressing roll device and a defibering machine. The bamboo chip defibering, and bamboo green and bamboo yellow removing pressing roll device comprises tooth form pressing roll groups arranged on a rack assembly and preforming defibering to the upper surface and / or the lower surface of a bamboo chip; the tooth form pressing roll groups comprise a left inclined pressing roll group and a right inclined pressing roll group, and the left inclined pressing roll group and the right inclined pressing roll group are arranged in a pairing and symmetry mode; the angel alpha formed between the shaft axis of a main roll shaft of the left inclined pressing roll group and the forward direction of the bamboo chipis equal to 180 degrees minus an angel beta, and the angle beta is formed between the shaft axis of a main roll shaft of the right inclined pressing roll group and the forward direction of the bamboochip. According to the bamboo chip defibering, and bamboo green and bamboo yellow removing pressing roll device and the defibering machine, design is reasonable, the structure is compact, and the useis convenient.

Description

technical field [0001] The invention relates to a pressing roller device for decomposing bamboo chips and removing bamboo green and bamboo yellow and a decomposing machine. Background technique [0002] Bamboo green and bamboo yellow can be bamboo green or bamboo yellow. Bamboo green is in terms of color. The outer skin of bamboo is green when it is fresh, and it is called bamboo green, and the inside of the bamboo cavity turns yellow. One side is called bamboo yellow. The cellulose in the bamboo green part was 42.94%, and the total lignin was 25.23%; the cellulose in the bamboo yellow part was 42.16%, and the total lignin was 24.72%. [0003] To make recombined bamboo, it is necessary to cut the moso bamboo into pieces, then put the bamboo pieces into pairs of toothed rollers arranged up and down for pressing and loosening, and use the sharp teeth of the rollers to create the pressing point of the bamboo, and the bamboo along its fiber direction Longitudinal semi-separati...

AI Technical Summary

Problems solved by technology

Its shortcoming is that the former causes waste of materials, because the green bamboo is very thin, the thickness is only less than 0.3mm, and the shape of the bamboo slices is irregular from the beginning to the end. Remove some; the disadvantage of the latter is that the removal is not clean, because the diameter of the steel wire of the steel brush is small, it cannot form surface contact with the bamboo during the contact and friction process, and it is easy to form a blank area, and the steel wire is bent for a long time to produce permanent deformation and cannot rebound. it won't work anymore
