Abstract

The invention discloses a cotton fiber transfer device, which comprises a cotton supporting plate, an upper cover plate, a saw blade roller, a licker-in roller and a saw blade rear cover plate. The distance between the saw blade roller and the licker-in roller and the radian of the saw blade roller covered by the saw blade rear cover plate can be set such that the number N of turns required by cotton fiber transferring can be attained; according to a critical diameter formula of a cyclone separator, the speed and diameter of the saw blade roller can be set according to a critical diameter formula of a cyclone separator such that thickness B distribution of a generated cotton fiber floating layer is attained; a lowest linear speed ratio of the licker-in roller to the saw blade roller is setaccording to chord lengths S of intersection areas of the cotton fiber floating layers having different thicknesses B with the licker-in roller. The cotton fiber impurity removal device is additionally provided with an impurity removal plate, a rear cover plate, an air supplement opening and an upper cover plate on the basis of the cotton fiber transfer device, mounting parameters are refined, and therefore, noise reduction and impurity removal are achieved.

Description

technical field [0001] The invention relates to the field of cotton primary processing machinery, in particular to a cotton fiber impurity removal device and method based on a cotton fiber transfer device. Background technique [0002] Sawtooth gin and sawtooth stripping machine are the main equipment in the cotton primary processing machinery. Their functions are as follows: [0003] Such as the patent CN203668559U, the sawtooth gin adopts the combination of the saw roller and the brush roller, the saw roller pulls the cotton fiber through the rib gap, filters the cotton seeds, and then separates the cotton fiber on the saw roller through the brush roller. Brush it down, then collect and compact it and transport it out of the machine; the surface of the cottonseed processed by the gin still has a part of short and dense short-staple fibers attached to it, and its content is equivalent to about 6.7% of lint, which is a fiber resource that cannot be ignored. A kind of mechan...
