A kind of bamboo tube continuous spiral opening equipment and bamboo fiber acquisition method

Abstract

The invention discloses a bamboo tube continuous helical fiber opening equipment and a bamboo fiber acquisition method. The device includes a pushing device and a bamboo tube twisting device; the pushing device includes a pushing frame and a first frame with horizontal straight guide rails; the pushing frame is transverse There is a boss for realizing the axial positioning of the bamboo tube. The outer side wall of the boss is evenly provided with several positioning pieces along the circumferential direction. The positioning pieces can be inserted into the bamboo tube to realize the circumferential positioning of the bamboo tube; Reciprocating movement along the guide rail; the bamboo tube torsion device includes a first friction wheel that can rotate along the central axis; the first friction wheel is located at the end side of the guide rail, and the side of the first friction wheel opposite to the boss is provided with a clamp for fixing the bamboo tube Holder. The invention can effectively destroy the inner and interlayer matrix structure of the bamboo tube through the shear stress in the circumferential direction, and the spiral motion of the bamboo tube can accelerate the separation between the fibers, so evenly separated bamboo fibers can be obtained, and the non-destructive separation of fiber bundles is realized; Fiber opening also improves production efficiency.

Description

technical field [0001] The invention belongs to the field of bamboo processing, and in particular relates to a bamboo tube continuous spiral opening equipment and a method for obtaining bamboo fibers. Background technique [0002] Bamboo fibril, also known as native bamboo fiber or bamboo fiber, is a new natural fiber developed in recent years. It is a bundle of fibers made by directly processing bamboo by physical and mechanical methods. Bamboo fiber raw material comes from natural renewable resources, and the product is biodegradable after use, which meets the requirements of environmental protection and is a new material with broad prospects. In recent years, bamboo fiber has begun to be used in the field of composite materials such as mattresses and car interiors. The mechanical methods used in the production of existing bamboo fibers are the rolling method and the carding method. Before machining, the whole bamboo or bamboo chips are softened, and then processed along...
