A device for crushing dried cannabis stems

Abstract

The invention discloses a rolling method and a corresponding rolling device for dry hemp stems. The rolling method comprises the following steps: the stems are fed in a manner that the length direction of the stems is parallel to the length direction of rollers, the stems are subjected to rod breaking rolling, plane rolling, bending rolling and spiral rubbing rolling sequentially and then subjected to bast and stick separation, and bast fibers are sent out in a scattered manner and enter follow-up decortication processing. The rolling device comprises multiple pairs of rollers which are meshed vertically and arranged sequentially in front-back direction, the rollers comprise spike tooth rollers, pattern flat rollers, main and auxiliary concave-convex rollers and helical tooth rollers, spike teeth on the outer surfaces of the spike tooth rollers puncture the stems when roller bodies roll the stems; bulges on the outer surfaces of the pattern flat rollers increase the friction between the stems and the roller bodies, and blockage can be avoided; convex teeth and concave grooves on upper rollers and lower rollers of the main and auxiliary concave-convex rollers are arranged in a main and auxiliary paired manner, and the stems can be bent when rolled by the roller bodies; helical teeth on the outer surfaces of the helical tooth rollers enable the roller bodies to rub the stems horizontally when rolling the stems longitudinally.

Description

technical field [0001] The invention relates to a stripping process of hemp fibers, in particular to a rolling method of dried hemp stems and a corresponding rolling device. Background technique [0002] Hemp (referring to industrial hemp, the same below) fiber has the properties of moisture absorption, breathability, antistatic, heat resistance, UV protection, antibacterial, sound insulation, etc., and has become a world-recognized high-quality natural textile fiber raw material. "Natural" today, hemp textiles are becoming more and more popular. [0003] In recent years, my country's hemp industry has developed rapidly, and the planting area and fiber output have increased year by year. The total output of hemp fiber in my country has increased from 100,000 tons / year in 2010 to 310,000 tons / year in 2015. However, because the overall planting scale of hemp fiber in my country is not large, in the past, it was mainly scattered and small-scale planting. The harvesting and pee...

Problems solved by technology

However, since the hemp stalks are fed in a way that the length direction is perpendicular to the length direction of the rolling roller, the effect of hemp stripping is greatly limited and cannot meet the harvesting and processing needs of large-scale cultivation of hemp
