Chinese hemp stem-cracking mechanism

Abstract

The invention discloses a hemp straw breaking mechanism, which belongs to the technical field of finished product machinery, and comprises a frame (1), a bumper pin (2), rollers (3) and a retaining spring (4). The frame (1) is arranged at the outer side of the mechanism, the bumper pin (2) is arranged between the rollers (3), and the rollers (3) are arranged inside the frame (1) and driven by a roller, a roller shaft and a driving gear. The hemp straw breaking mechanism that is provided by the invention feeds retted hemp straws into the mechanism, and leads the rollers of the straw breaking mechanism to squeeze straw bar cores into small woody crumbs that have easier bast separation. The hemp straw breaking mechanism can be widely applied to the peel and rod separation process of hemp crops, overcome the machine blockage and entwinement phenomenon in traditional straw breaking processes, correspondingly avoid consequent frequent vehicle stopping, and simultaneously improve processing efficiency and finished product quality.

Description

technical field [0001] The invention relates to a mechanism widely used for separating the bark and stem of hemp crops, in particular to a mechanism for crushing hemp stems. Background technique [0002] my country is a major exporter of chemical fiber, cotton, textiles and clothing, and a major producer of textiles. [0003] In terms of chemical fiber, the output of synthetic fiber in my country accounted for more than 70% of the total fiber in 2002, and accounted for 66.7% in 2003, both higher than the international ratio of 60%. The ratio of natural fiber and chemical synthetic fiber is out of balance. In today's increasingly tense energy environment, the current situation of high input and low output in the processing process makes people say no to chemical fiber. In terms of natural fibers, my country is a big cotton-producing country. However, due to years of continuous planting, diseases and insect pests are becoming more and more serious, requiring a large amount of...

AI Technical Summary

Problems solved by technology

[0005] 1) The xylem of hemp is denser, thicker and harder, with high lignin content and high hardness, which has great mechanical wear and tear, and the rod core removal effect of ordinary crushing stem mechanism is not good;

[0006] 2) The height of the hemp plant is 2-3 times that of the flax, and the processing of the common stem crushing machine is not thorough, resulting in a lot of dead crumbs in the processed hemp, and a high rate of duplication of hemp;

[0007] 3) In the ordinary stem crushing machine, the roller tooth density is high, the processing strength is high, and the fiber is easy to be broken, causing entanglement and crash
