Plant fiber shearing device, shearing method and shearing device manufacturing method

Abstract

The invention discloses a plant fiber shearing device, a shearing method and a shearing device manufacturing method. The plant fiber shearing device comprises a bracket. A shearing box is arranged onthe bracket. A twin-screw shearing mechanism is arranged in the shearing box. A feeding opening is formed in the left end of a top side plate of the shearing box, a discharging opening is formed in the right end of a bottom side plate of the shearing box, and a shaft hole is formed in a left side plate of the shearing box. A power mechanism is connected to the twin-screw shearing mechanism througha rotating shaft. The rotating shaft penetrates through the shaft hole and extends out of the shearing box. By means of the plant fiber shearing device, the shearing method and the shearing device manufacturing method, ordered and regular cutting of plant fibers can be realized, so that the cutting fineness and lengths of the plant fibers can be controllable, and the cutting quality and production efficiency of the plant fibers are guaranteed; and meanwhile, severe collision between the plant fibers and a cutting part and severe collision between the plant fibers in the cutting process are greatly relieved, the structures of the plant fibers are prevented from being damaged, and the mechanical property of the plant fibers is ensured. The shearing method is simple, and the device manufacturing method ensures the stability of the structure.

Description

technical field [0001] The invention relates to the technical field of plant fiber processing, in particular to a plant fiber shearing device, a shearing method and a manufacturing method of the shearing device. Background technique [0002] my country's plant fibers are widely distributed and have promising application prospects, but the per capita forest resources are seriously insufficient. Plants are processed by industry and agriculture to produce a large amount of solid waste, only part of which is used for combustion and power generation. The large amount of stacking has caused great environmental pollution and waste of resources. . Based on the needs of national development, it is proposed to focus on improving resource utilization efficiency, focus on technological innovation and system innovation, continuously improve and expand the comprehensive utilization technology level, equipment capacity and application benefits of bulk solid waste, and promote the "high-valu...

Problems solved by technology

The vertical jaw crusher changes the grinding action into rubbing action, but the feeding port is very small, and the raw material needs to be crushed or cut short before feeding, and it is difficult to process rough and hard raw materials, and the processing efficiency is not high

The quality of the fiber prepared by the blade breaker is good, but the input particle size is also limited, and the equipment is intermittently processed, so the preparation efficiency is low, so it can only be used as a laboratory fiber processing equipment

The hammer mill has no requirements on the feed particle size, but when crushing sticky and wet materials, it is easy to block the sieve gap, so it is easy to cause downtime and affect production efficiency

[0005] When the above fiber processing equipment cuts plant fibers, the principle is to achieve random and irregular crushing and cutting of fibers through high-speed rotating cutting parts. The principle is similar to stirring and mixing, which will lead to repeated repetition of some fibers. The first cutting becomes powder, while some fibers are not cut and become coarse fibers, the fiber fineness and length are uneven, the cutting effect is uneven, and the quality of the final product cannot be guaranteed; and in this irregular movement process, the plant The violent collision and rubbing between the fiber and the cutting parts and between the plant fibers will cause the structural damage of the fiber itself, which will affect the mechanical properties of the fiber

In addition, the existing plant fiber shearing equipment still has problems such as easy passivation of the tool, poor corrosion resistance, and serious tool wear.
