Equipment for spirally splitting bamboo strips and bamboo fiber obtaining method of equipment

Abstract

The invention discloses equipment for spirally splitting bamboo strips and a bamboo fiber obtaining method of the equipment. The equipment comprises a feeding system and a spiral splitting system. The spiral splitting system comprises a main shaft and an outer cylinder which are conical and have cross sections gradually reduced along the feeding direction; the main shaft is connected with a second motor, and double spiral blades are axially arranged on the outer surface; two spiral blades of the double spiral blades have the same spiral direction and are symmetrically arranged in the axial direction, and the screw pitch of the double spiral blades is gradually reduced in the feeding direction; the outer cylinder is coaxially sleeved outside the main shaft, the inner wall of the cylinder does not influence the rotation of the double spiral blades, and the cylinder, the double spiral blades and the main shaft jointly form a splitting channel capable of enabling bamboo strips to move spirally; and bamboo strips to be treated can enter an inlet of the splitting channel after being fed by the feeding system. In the bamboo splitting process through the equipment, the integrity of fiber tissue can be kept to the maximum extent, fiber structure damage and strength damage are avoided, and lossless separation between fiber bundles is achieved.

Description

technical field [0001] The invention belongs to the field of bamboo processing, and in particular relates to a device for spirally opening bamboo strips and a method for obtaining bamboo fibers. Background technique [0002] Due to the wide range of bamboo resources in my country and the short renewable cycle, the processing and utilization of bamboo have been booming in the past 30 years. As a new type of natural fiber, bamboo fiber has begun to be used in mattress core materials, and research in other composite materials such as automotive interiors has also increased significantly. The rapid growth of the bamboo fiber market requires advanced bamboo fiber processing technology and equipment. At present, the extraction of long bamboo raw fibers at home and abroad is only in the technical research stage, and no company has produced and sold such equipment. There are few competitive products in the target market, and the market is in a "vacuum state". [0003] The key proc...

Problems solved by technology

The present invention proposes to use bamboo strips after splitting and de-yellowing or stratified bamboo strips as a processing unit, and softening bamboo strips can change the problem of uneven softening treatment of bamboo tubes or bamboo strips in the existing technology; at the same time, bamboo strips are layered and classified The technology can effectively improve the problem of uncontrollable fiber fineness in the prior art, and improve the uniformity index of fiber extraction
