Method and equipment for processing sisal leaves

Abstract

The invention discloses a method for processing sisal leaves. The method includes the steps of firstly, squashing the sisal leaves; secondly, squeezing and dewatering the squashed sisal leaves; thirdly, scraping mesophyll; fourthly, drying; fifthly, packaging and storing. The invention further discloses equipment for processing the sisal leaves. The equipment comprises a feeding device, a sisal leaf squashing device, a squeezing and dewatering device, a first sisal leaf clamping device, a second sisal leaf clamping device, a first mesophyll scraping device, a second mesophyll scraping device and a blower. The method has the advantages that the method is novel and unique, the sisal leaves are squashed first, the mesophyll is scraped after the squashed sisal leaves are squeezed and dewatered, independent polishing and sisal leaf residue squeezing and dewatering are avoided, processing procedures are reduced while squeezing and dewatering efficiency, mesophyll scraping efficiency and fiber quality are increased, mesophyll scraping cost is lowered, and fiber extracting rate is increased. The equipment is simple in structure, simple to operate, low in manufacturing cost, high in production efficiency, low in application cost, and the like.

Description

technical field [0001] The invention relates to a technology for mechanically processing sisal hemp, in particular to a processing method and processing equipment for sisal hemp blades. Background technique [0002] Sisal, also known as pineapple hemp, is a perennial tropical hard leaf fiber crop. It is the most widely used hard fiber in the world today. It has a tough texture, wear resistance, salt and alkali resistance, and corrosion resistance. It is used in various industries such as transportation, fishery, petroleum, metallurgy, etc., and has important economic value. [0003] The existing sisal processing equipment includes: manual beating, hand-pulled hemp scraping machine, semi-automatic hemp scraping machine and automatic hemp rowing and hemp scraping machine. The first three equipments are relatively backward in technology and low in production efficiency, and have been gradually eliminated. The most advanced is the automatic rowing and scraping machine, but at p...

Problems solved by technology

[0003] The existing sisal processing equipment includes: manual beating, hand-pulled hemp scraping machine, semi-automatic hemp scraping machine and automatic hemp rowing and hemp scraping machine. The first three equipments are relatively backward in technology and low in production efficiency, and have been gradually eliminated. The most advanced is the automatic rowing and scraping machine, but at present the production process of most of the medium and large automatic rowing and scraping machines is: rowing - scraping - first round of water pressure - polishing - second round of water pressure - drying, Although its degree of automation has been improved, it has the following two defects: (1) the scraping of hemp is not clean, because the hemp residue has a large water content and strong adhesion, so it needs to be polished; (2) the dehydration is not clean, because the sisal The fibers are small and the water pressure is not complete

The existing sisal processing method has many procedures and is complicated, the fiber output rate is low, and the slag needs to be subjected to secondary water pressure treatment

[0004] Most of the scraping devices of the existing sisal processing equipment are as described in the patent 2011101574531. The knife ball and the concave plate cooperate to scrape the sisal blades. This type of scraping device wears the concave plate relatively, and the concave plate maintenance costs are extremely high
