A material cutting device for a biomass fuel pellet machine

Abstract

The invention relates to a material cutting device of a biomass fuel pellet machine, which comprises a material cutting ring gear arranged coaxially with the upper edge of a ring die, several material cutting knife seats fixedly arranged on the lower surface of the material cutting ring gear, The cutting knife on the cutting knife seat, the cutting knife seat includes a horizontal plate and a vertical plate integrally connected, its overall vertical section is in an inverted L shape, and the horizontal plate is distributed in a circular array along the axis of the ring die, The side of the vertical plate forms a certain angle with the cutting surface of the outer side of the ring die; the cutting knife includes a metal cutting knife and a soft cutting knife, and the metal blade is fixed on the vertical plate along the direction of rotation of the cutting ring gear. One side of the vertical plate, the soft cutter is set on the other side of the vertical plate; the present invention uses metal cutters and soft cutters at the same time, adopting such a double-knife design can not only facilitate the cutting of particles with different particle sizes, but also set The soft cutter on the other side of the metal cutter also acts as a scraper.

Description

technical field [0001] The invention belongs to the field of biomass fuels, in particular to the field of material cutting devices for biomass fuel particle molding machines. Background technique [0002] Biomass pellet fuel is a granular environmentally friendly new energy produced by processing straw, straw, rice husk, peanut shell, corn cob, camellia oleifera husk, cottonseed husk, etc. Compared with traditional fuels, biomass pellet fuel not only has economic advantages but also It has environmental benefits and fully meets the requirements of sustainable development. In addition, the biomass fuel is made into pellets, which not only compresses the volume, saves storage space, but also facilitates transportation and reduces transportation costs; at present, in the existing biomass pellet machine technology, there are various forms of pellet cutting, The material cutting effect is uneven, and there are problems that the length of biomass particles is different, and there...
