Leafcutter ant palate-based bionic banana fiber extraction device

Abstract

The invention discloses a leafcutter ant palate-based bionic banana fiber extraction device. The device comprises a rack, a cutting mechanism and a flattening mechanism located on the front side of the cutting mechanism, the cutting mechanism comprises a fixed knife wheel, a fixed knife is arranged on the surface of the fixed knife wheel, an L-shaped notch is formed in the front end of the fixed knife, big tooth edges and small tooth edges are staggerly distributed at the L-shaped notch, the flattening mechanism comprises an upper pressing roller and a lower pressing roller which are vertically arranged in parallel, an upper block sleeves the upper pressing roller, a lower block sleeves the lower pressing roller, and the top of the rack is in bolt connection with a support which is internally provided with the upper block and the lower block. Accordingly, by means of V-shaped cutting edges formed between the big tooth edges and the small tooth edges, the impurity rate and winding blocking can be effectively reduced, due to the fact that the impurity rate is reduced, the finally actually prepared fiber preparation rate is increased, the contact area between the fixed knife and the fiber surface is increased, the processing efficiency is improved, damage of the fixed knife to banana fiber in the processing process is reduced, the finished product rate is increased, and blocking is reduced.

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...

Problems solved by technology

[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
