A bionic banana fiber extraction device based on the mandible of leaf-cutter ants

Abstract

The invention discloses a banana fiber extraction device based on the bionicity of the upper jaw of leaf-cutter ants, which includes a frame, a cutting mechanism, and a flattening mechanism located on the front side of the cutting mechanism. The front end of the knife and the fixed knife is provided with L-shaped notches, and the L-shaped notches are staggered with large and small tooth edges. The flattening mechanism includes two upper and lower pressure rollers arranged in parallel up and down. The upper pressure roller is sleeved with an upper The lower pressure roller is sleeved with the lower block, the top of the frame is bolted to the support, and the upper block and the lower block are arranged in the support. The present invention can effectively reduce the content of The impurity rate and winding blockage reduce the impurity content rate, improve the final fiber preparation rate, increase the contact area between the fixed knife and the fiber surface, improve the processing efficiency, and reduce the damage of the fixed knife to the banana fiber during processing. Yield reduces clogging.

Description

technical field [0001] The invention relates to the technical field of planting machinery, in particular to a bionic banana fiber extraction device based on the mandible of leaf-cutter ants. Background technique [0002] Banana stalk fiber is a new natural fiber in recent years. It has good hygroscopicity, air permeability, and biocompatibility. Using banana stalk fiber can develop green ecological clothing and produce degradable packaging materials. The products under development are in While satisfying people's consumption, it has found a new way for farmers to increase their income. [0003] Banana stalk fiber has low strength and is easy to break, and its use requires a low impurity content, but the existing scraping machine cannot meet its extraction process requirements. The main reason is that the fixed knife of the scraping machine is a flat-edged knife, and the flat-edged knife The blowing intensity of the blower is high, and the point of action of the force is alm...

[0003] Banana stalk fiber has low strength and is easy to break, and its application requires a low impurity content, but the existing scraping machine cannot meet its extraction process requirements. The main reason is that the fixed knife of the scraping machine is a flat-edged knife, and the flat-edged knife The impact strength of the blower is high, and the point of action of the force is almost on a straight line, which can easily cause the stem fiber to break and form broken fiber impurities, resulting in a high impurity rate in the collected crude fiber; at the same time, it is also easy to cause the The shredded fibers are entangled in the recovery and separation area, and the coarse fibers cannot be normally drawn into the output roller to form a blockage
