Fiber decorticating device of pineapple leaf decorticating machine and intermittent pineapple leaf decorticating machine

Abstract

The fiber decorticating device of the pineapple leaf decorticating machine comprises a rack, a decorticating driving motor, a push rod assembly, a cylindrical cam assembly, a swing rod assembly, a pull wire, a pull wire and a pressing assembly are arranged on the rack, and a left rocker arm and a right rocker arm are hinged to the two sides of the upper portion of the rack respectively. The downward-pressing assembly is arranged between the left rocker arm and the right rocker arm, the opposite ends of the left rocker arm and the right rocker arm are connected with the two ends of the downward-pressing assembly through pull wires respectively, one end of the pull wire is connected with the other end of the left rocker arm, and the other end of the pull wire penetrates through the push rod assembly to be connected with the other end of the right rocker arm. The decorticating driving motor drives the cylindrical cam assembly to rotate to drive the swing rod assembly to move, the swing rod assembly pushes the push rod assembly to move when moving, and the push rod assembly pulls the other ends of the left rocker arm and the right rocker arm through the pull wire to enable the pressing assembly to be lifted or pressed down when moving. The pineapple leaf fiber processing quality and production efficiency of the pineapple leaf fiber scraping machine are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a fiber stripping device of a pineapple leaf hemp scraping machine and an intermittent pineapple leaf hemp scraping machine. Background technique [0002] The fiber extracted from pineapple leaves, commonly known as pineapple hemp, is the only natural fiber in the world that has three major properties of antibacterial, deodorizing and anti-mite. It can be made into high-quality textile materials for functional textiles after deep processing. Our country has initially taken shape and has broad prospects for development. Extracting pineapple leaf fiber with a traditional hand-pulled hemp scraping machine is not only labor-intensive but also low in extraction efficiency. Chinese invention patent discloses an intermittent pineapple leaf scraping machine, publication number CN104746147B, this invention saves more labor than the traditional hand-pulled scrap...

Extracting pineapple leaf fiber using a traditional hand-pulled hemp scraping machine is not only labor-intensive but also low in extraction efficiency

Chinese invention patent discloses an intermittent pineapple leaf scraping machine, publication number CN104746147B, this invention saves more labor than the traditional hand-pulled scraping machine, but the pineapple leaf fiber of this invention is processed, and the upper pressing roller of the machine presses the fiber end tightly Rotate, when the pineapple leaf fiber is reversely drawn out from the hemp scraping mechanism, because the pineapple leaf fiber is highly viscous and light in weight (about 10g), it cannot fall away from the upper pressing roller by its own weight, and it is very easy to be carried by the upper pressing roller When the pineapple leaves are moving back and forth on the conveyor belt to the direction of the hemp scraping mechanism at both ends, the position between the pineapple leaves and the conveyor belt changes due to their weight, which causes the pineapple leaves to The stroke of feeding the hemp scraping mechanism is shortened, resulting in the middle part of the pineapple leaf still being a leaf, which cannot be fed to the hemp scraping mechanism to process and extract the pineapple leaf fiber, and the phenomenon of "ring hemp" appears, which seriously reduces the quality and production efficiency of the pineapple leaf fiber
