Fiber low-damage output device for continuous blowing-carding feeding hopper

Abstract

The invention relates to a fiber low-damage output device for a continuous blowing-carding feeding hopper. A dust absorption part and an output roller part are arranged between an L-shaped lower conveying channel and a dripping plate; an upper air return box and a lower air return box in the dust absorption part are vertically and symmetrically distributed along the bottom surface of the dripping plate; an upper output roller and a lower output roller in the output roller part have identical radial dimension and are vertically and symmetrically distributed along the bottom surface of the dripping plate; the dripping plate is arranged at an outlet of the output roller part; an included angle between the dripping plate and a horizontal plane is 10-25 degrees; and the lower conveying channel is connected with the output roller part through a circular arc curve. Because the conveying channel is changed from the prior vertical channel into the L-shaped channel with the circular arc curve, the prior output state of fibers can be changed; and the length direction of the output fibers is vertical to a feeding roller axis of a carding machine, so that the cohesive force of the fibers among rock cotton is improved, and the faultage is reduced, and the damage to the fibers is greatly reduced.

Description

Technical field: [0001] The invention relates to a blowing and carding combined feeding box, in particular to an output device of the blowing and carding combined feeding box. Background technique: [0002] The blowing-carding and feeding box is one of the indispensable key equipment in the blowing-carding textile process. figure 1 As shown, it includes a cotton head 1, a dust discharge pipe 2, a blower 3, an upper cotton conveying channel 4, an opening part, a cotton conveying lower channel 6, a dust suction part, an output roller part and a cotton dripping board 9, wherein the suction The dust part, the output roller part and the cotton dripping plate 9 constitute the output device of the cotton box, and the cotton distribution head 1 and the dust discharge pipe 2 are all arranged on the top of the cotton box, and the cotton distribution head 1 communicates with the upper cotton conveying channel 4, and the cotton is loosened. The components are arranged at the intersecti...

Problems solved by technology

[0007] ③The airflow layer released from the carding board brings out some impurities, and the circulating airflow makes the impurities mix into the cotton layer, causing secondary pollution of the cotton layer.
