Efficient cotton crusher used for producing cellulose acetate butyrate

Abstract

The invention relates to the technical field of cotton crushers, and discloses an efficient cotton crusher used for producing cellulose acetate butyrate. The efficient cotton crusher comprises a bottom plate. The upper end of the bottom plate is fixedly connected with a crushing box through a support. The upper end of the crushing box communicates with a feeding hopper. The inner wall of the bottom of the crushing box is fixedly connected with a triangular guide block. The upper end of the triangular guide block and the inner wall of the top of the crushing box are rotationally connected withthe same first crushing rod through a ball bearing. The upper end of the first crushing rod penetrates through the upper end of the crushing box and is fixedly connected with a first driven bevel gear. The upper end of the crushing box is fixedly connected with a crushing motor in a clamped manner. An output shaft of the crushing motor is fixedly connected with a first driving bevel gear engaged with the first driven bevel gear. The efficient cotton crusher used for producing cellulose acetate butyrate has the advantages that multi-stage gradual cotton crushing operation can be achieved, and the cotton crushing efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of cotton crushers, in particular to a high-efficiency cotton crusher for producing cellulose acetate butyrate. Background technique [0002] Cellulose acetate butyrate is used to make high-transparency, weather-resistant plastic substrates, films and leveling agents for various coatings, film-forming substances, etc. The increase of butyryl content will reduce the density and expand the solubility range. Containing 12% to 15% of acetyl groups and 26% to 29% of butyryl groups. Transparent or opaque pellets, tough quality, good weather and cold resistance. [0003] In the production process of cellulose acetate butyrate, it is necessary to use a cotton shredder to crush the cotton to obtain raw materials for production. The current cotton shredder has a single structure and a limited degree of shredding, which cannot make the cotton quickly shredded to a suitable demand, which is not convenient for cotton ...
