Plucker roller for cotton feeder

Abstract

The invention discloses a plucker roller for a cotton feeder capable of easily penetrating through heavy and special impurities, comprising an expansion cylinder, along with the axis O-O direction of the expansion cylinder, a plurality of J corner star-like discs with J tips are sequentially arranged with one another, wherein J is more than or equal to 6 and is less than or equal to 8, the expansion cylinder sequentially penetrates through the centers of the discs, the discs are fixed on the expansion cylinder, an inclined angle between the discs and the axis O-O is alpha, wherein alpha is more than or equal to 60 degrees and is less than or equal to 80 degrees, one point on the axis O-O is taken as a datum point, the leaning directions of the discs at one side of the datum point are just opposite to that of the discs at another side of the datum point, the distance occupied by each disc on the axis O-O is Y, and Y is more than h and is less than Jh / 2, the axial shortest distance Z between the two adjoining discs at the same side of the datum point is less than or equal to h, the axial distance L between the two adjoining discs at the same side of the datum point is equal to Y+Z and is more than 2h, and the beating gas h is less than or equal to 60mm.

Description

technical field [0001] The invention relates to a cotton feeding machine, in particular to an opening roller of the cotton feeding machine. Background technique [0002] like figure 1 and figure 2 As shown, the main body of the opening roller of the existing cotton feeder is the cylinder 11, with the cylinder axis O-O direction as the row, and six rows of radial spikes 12 are evenly distributed on the cylinder, of which the first, third and fifth rows are the same , the same for columns 2, 4, and 6. On the same column, the axial spacing (that is, tooth pitch) between two adjacent spikes is L, and on two adjacent columns, the axial spacing between two adjacent spikes is h, and L=2h. On the same circumference, there are 3 thorns evenly distributed, that is, the opening roller rotates three times a week to open the seed cotton at the same point. In order to avoid the formation of beating blind spots and reduce manufacturing costs, the beating gap h should be adapted to ...

AI Technical Summary

Problems solved by technology

Inevitably, the seed cotton is mixed with important impurities (such as bricks, stones, wood blocks, etc.) whose size is larger than L. During the working process of the cotton feeder, these important impurities are not easy to pass through the axial gap L between two adjacent spikes. , constantly hitting and rubbing against the thorns, it is easy to cause a fire
