Fiber extractor of sisal leaves

Abstract

The invention discloses a fiber extractor of sisal leaves. The fiber extractor comprises a feeding device, a fiber extraction device and a discharging device in sequence. The fiber extraction device includes a conveyor chain of which one side is provided with a fiber extraction roller A, a blower and a fiber extraction roller B in sequence in the conveying direction of the sisal leaves. The feeding device is connected with the discharging device through the conveyor chain. The fiber extraction device further comprises a clip wheel A and a clip wheel B which are in transmission connection withthe conveyor chain. The conveyor chain is wound around the clip wheel A from below and wound around the clip wheel B from above. The fiber extraction roller A extracts fibers from sisal leaves betweenthe clip wheel A and the conveyor chain. The fiber extraction roller B extracts fibers from sisal leaves between the clip wheel B and the conveyor chain. According to the structure, the fiber extractor of the sisal leaves can be used for extracting the fibers from the sisal leaves in two steps, hence, not only can the fiber extraction efficiency be ensured, but also fiber extraction can be conducted on each whole sisal leaf, there is no fiber extraction dead angle, and the fiber extraction quality is improved.

Description

technical field [0001] The invention relates to the technical field of scraping sisal leaves, in particular to a sisal leaf scraping machine. Background technique [0002] Hemp fiber refers to fibers obtained from various hemp plants, including bast fibers from the cortex of annual or perennial herbaceous dicotyledonous plants and leaf fibers from monocotyledonous plants. Bast fiber crops mainly include ramie, jute, green hemp, hemp, flax, apocynum and kenaf. Generally speaking, hemp fiber is a high-strength and low-elongation fiber, and its breaking strength is 5.0~7.0cN / dtex (2.6~4.5 for cotton fiber and 3.0~3.5 for silk). This is mainly because hemp fibers are mainly bast fibers, and bast fibers are the basic skeleton of plants, with high crystallinity and orientation, and the fibrils are distributed in a layered structure along the fiber radial direction. For example, flax has 90% crystallinity and nearly 80% orientation. Because of its high crystallinity and orientat...

AI Technical Summary

Problems solved by technology

However, the current scraping machines for hemp fiber scraping process all need to manually feed the sisal leaves one by one, resulting in greater labor intensity for the operator; The middle part of the leaf is clamped by the conveyor chain and the clamping wheel, and then both sides are scraped at the same time. Although the sisal leaves on both sides of the conveyor chain can be scraped quickly and effectively, the parts of the sisal leaves that are in contact with the conveyor chain cannot be scraped. Direct scraping treatment still needs to be scraped again at the position of the sisal leaf through the subsequent process
