The invention discloses a roller cotton collecting
machine for refined cotton, and relates to the technical field of
textile processing. The roller cotton collecting
machine comprises a supporting plate, a left supporting column and a right supporting column, the bottoms of the left supporting column and the right supporting column are fixedly connected with the top of the supporting plate, and the outer surfaces of the left supporting column and the right supporting column are symmetrically arranged. A cotton collecting mechanism is arranged between the sides, close to each other, of the outer surfaces of the left supporting column and the right supporting column, the cotton collecting mechanism comprises a cotton collecting
barrel, a left rotating column and a right rotating column, and one end of the left rotating column and one end of the right rotating column are rotationally connected with the outer surfaces of the supporting columns. According to the roller cotton collecting
machine for the refined cotton, through the combination of the structures such as the cotton collecting
barrel, a cotton suction net, a draught fan, the rotating columns and an
exhaust pipe, negative pressure is generated in a vacuum cavity, the cotton collecting
barrel can adsorb cotton fibers through the cotton suction net and adsorption holes, and the situation that selling is affected due to the fact that the refined cotton is polluted in the
processing process is avoided; and through the combination of the structures, the problem that selling is easily influenced when the refined cotton is processed by a traditional cotton collector is solved.
