Industrial hemp scapus fiber separator

Abstract

The invention discloses an industrial hemp scapus fiber separator which comprises a material feeding table, a stalk rolling device and a hemp combing carding device, sequentially arranged, wherein the stalk rolling device comprises multiple pairs of upper and lower meshed rollers; every two adjacent rollers meshed with each other through convex teeth and grooves in the outer walls of roller bodies to efficiently roll stalks, so as to separate peels from scapuses, and hemp scapuses are rolled into tiny hemp combings which are attached to the surface of fiber; the rolled hemp scapuses are conveyed to the hemp combing carding device; the hemp combing carding device comprises multiple pairs of upper and lower meshed carding drums; a plurality of rows of carding components are arranged on the outer wall of each carding drum along the axial direction; a splayed carding gap is formed between every two adjacent rows of carding component; a carding strip is arranged on the side wall of each carding component; the carding components repeatedly tap and card the hemp combings to enable the hemp combings to be separated from the surface of the fiber, thus obtaining clean hemp fiber; the stalk rolling device is applicable to feeding the stalks along a direction both parallel to the axial direction of the rollers and perpendicular to the axial direction of the rollers; and the carding components can guarantee high efficiency and increase the hemp growth rate.

Description

technical field [0001] The invention relates to a hemp stripping machine, in particular to an industrial hemp stem fiber separator. Background technique [0002] Hemp (referring to industrial hemp, the same below) fiber has properties such as moisture absorption, breathability, antistatic, heat resistance, UV protection, bacteriostasis, and sound insulation, and has become a world-recognized high-quality natural textile fiber raw material. "Natural" today, hemp textiles are becoming more and more popular. [0003] But hemp is a bast fiber crop, and its stalks need to go through a process of "stripping" after harvesting to get the fibers from the stalks for textiles. Hemp stems can be roughly divided into epidermis (hemp husk), phloem (containing hemp fiber) and xylem (hemp bone) from outside to inside. It is very difficult to remove the hemp husk, hemp bone and phloem of the hemp stem to obtain clean hemp fibers, and "difficulty in peeling hemp" has become a bottleneck res...

Problems solved by technology

The hemp fresh stem peeling machine adopts the one-time feeding method of hemp peeling to peel hemp fresh skin. First, the effect of peeling hemp is limited, and second, the peeled fresh skin needs to be dried and then degummed to obtain fibers, which cannot meet the needs of northern my country. Mechanized Harvesting Requirements for Large-Scale Cannabis Cultivation

[0005] There are also kenaf peeling machines including feeding table, rolling device and flax carding device etc. at present, but its rolling device has the defects of low crushing stem efficiency and unsatisfactory rolling effect. It has the disadvantages of high impact force, large loss of fibers, and low rate of hemp growth. It cannot adapt to the fiber stripping of hemp stems such as hemp, and it is not suitable for the treatment of different hemp stems.
