Sisal processing method and sisal scraping device thereof

Abstract

The invention discloses a sisal processing method and a sisal scraping device thereof. The sisal processing method comprises the steps of: 1) arranging sisals and quantitatively feeding; 2) neatly spacing blades of the sisals; 3) stretching and conveying; 4) scraping the sisals: firstly clamping the base parts of the blades of the sisals; then scraping the tip parts of the blades of the sisals; clamping scraped tip fibre parts; and completely scraping the base parts of the remainder blades of the sisals; 5)squeezing water of straight fibres; 6) drying the straight fibres; and 7) packing and warehousing. The sisal scraping device comprises a sisal arranging and conveying mechanism, a first sisal clamping mechanism, a first knife ball mechanism, a second sisal clamping mechanism and a second knife ball mechanism; the base parts of the blades of the sisals are clamped by the first sisal clamping mechanism and are conveyed forwards; the tip parts of the blades of the sisals are scraped by the first knife ball mechanism; the scraped edge fibre parts are clamped by the second sisal clamping mechanism and are conveyed forwards; and the base parts of the blades of the sisals are scraped by the second knife ball mechanism. According to the invention, the extraction rate of the straight fibres and the comprehensive quality of the fibres are improved; and the production cost is reduced.

Description

technical field [0001] The invention relates to a method for processing sisal, and also relates to a hemp scraping device for realizing the above method. Background technique [0002] At present, sisal processing has experienced more than 40 years of processing history in Leizhou Peninsula. The development trend of its processing equipment is as follows: manual hammering, hand-pulled hemp scraping machine, semi-automatic hemp scraping machine, automatic row hemp scraping machine production line. The processing methods adopted by the above-mentioned processing equipment are to first scrape the base of sisal (1 / 3 of the length of sisal, about 45-50 cm), and then scrape the tip of sisal (2 / 3 of the length of sisal). According to the growth of natural sisal leaves and the distribution of fiber filaments, the fibers of the leaves are irradiated from the base of the leaves to the cutting part to the tip of the tail. Due to the consideration of the holding problem of sisal in proc...

AI Technical Summary

Problems solved by technology

Due to the consideration of the holding problem of sisal in processing, the short fibers of 45-50 cm distributed around the base of the blade are scraped off because they cannot be clamped during mechanical processing, so that the short fibers of about 45-50 cm The fibers are scraped off in the hemp residue, which affects the yield of straight fibers

In addition, because the second knife ball uses the combination of the hemp sprocket and the hemp chain to clamp the fiber, the fiber is drawn out in the interval between the chain and the sprocket, and a small amount of fiber will be broken during the operation of the chain and the sprocket. Among them, 18-20% of the straight fibers become short random fibers, which affects the fiber extraction rate
