Embodiment Construction

[0030] figure 1 It shows the schematic layout and working principle of the whole machine used for sisal fiber extraction equipment, including the feeding mechanism (1) composed of the feeding port and the transfer chain, the two left and right dehemping mechanisms composed of double drums (2) and (5), the crushing mechanism at the base of the hemp leaf (6), and the chain belt clamping and conveying mechanism (4) and (7).

[0031] The feeding chain, clamping chain, clamping belt and denumbing mechanism are arranged at an inclination of 45°, the conveying speed is about 0.3 m / s, and the speed of axial feeding and tangential pulling is about 0.21 m / s. The left and right desemping mechanisms are perpendicular to each other, the diameter of the drum is 200-300 mm, the linear speed is about 15 m / s, the length of the left demashing drum is twice the length of the right demashing drum, the crushing drum and the demashing drum are inclined at 45°, crushing The rolling speed is 1.4 tim...

Abstract

The invention provides a novel sisal fiber extraction method and device. The method comprises the steps that sisal leaves are crosswise fed into one hemp peeling mechanism from the middle of the sisal leaves, and fibers are obtained through direct reverse drawing. The device comprises a feeding mechanism, a sisal leaf clamping and delivery mechanism, a fiber clamping and delivery mechanism, a left hemp peeling mechanism and a right hemp peeling mechanism, sisal leaf base crushing mechanism, and a power and transmission device, wherein the sisal leaves and the fiber clamping and delivery mechanism are arranged in an inclined mode toward the hemp peeling mechanisms and perpendicular to the crushing mechanism, a chain and a belt are arranged in parallel and the delivery speeds are the same, and the linear speed of a crushing roller is 1.4 times those of the chain and the belt. Double-vane rolling cylinders with two vanes rotating in opposite directions serve as the hemp peeling mechanisms. The sisal leaves are crosswise fed into the left hemp peeling mechanism by the feeding mechanism, fibers are drawn out by the sisal leaf clamping chain and enter the fiber clamping belt, tip fibers are further drawn out, bases enter the right hemp peeling mechanism after winding around the shaft end of the crushing roller, and base fibers are reversely drawn out. By the adoption of the method and device in sisal fiber extraction, the per capita productivity of an existing device is improved by 2 to 3 times, and the productivity per kilowatt hour is improved by 1 to 2 times.

Description

technical field [0001] The disclosed technology relates to a new method suitable for sisal fiber extraction, and relates to a new equipment suitable for sisal fiber extraction. Background technique [0002] Sisal is a leaf fiber crop. The fiber cells are elongated. The cell cavity is large and long and the wall is thick. It has long fibers, white color, tough texture, elasticity, strong pulling force, abrasion resistance, acid and alkali resistance, and Corrosion, non-slip features, widely used in fishery, navigation, mining, transportation, oil fields and other businesses as well as weaving sisal carpets, handicrafts and other daily necessities. [0003] Sisal fiber extraction has experienced the development process from traditional manual to semi-mechanized and mechanized. However, the development of mechanized extraction technology has been slow in the past century, and it is hoped to design a safer and more efficient machine. [0004] Mainly contain horizontal feed typ...
