Drawing frame

Abstract

The invention discloses a drawing frame. The drawing frame comprises a sliver can, a drafting unit, a sliver collecting tube and a coiler can, the drafting unit is arranged between the sliver can andthe sliver collecting tube, and the sliver can is of a convoluted structure; the drafting unit successively comprises a cotton guide roller, a first drafting roller, a second drafting roller, a thirddrafting roller, a fourth drafting roller and a guiding roller from left to right; a dust removing unit is further disposed beside the drafting unit, and the dust removing unit includes a first dust hopper and a second dust hopper. The drawing frame has the advantages that the sliver can is arranged to be rotatably supported on a base, a plurality of storage cavities are formed in the sliver can,and when slivers in one storage cavity are used up, the sliver can is rotated, so that the next storage cavity is rotated to be aligned with a suction pipe; slivers are subjected to drafting for manytimes, the drafting effect of the slivers is effectively improved, and the irregularity of the slivers can be greatly reduced; through the arrangement of the dust removing unit, impurities on the surfaces of the slivers can be reduced, and the quality of the slivers can be improved.

Description

technical field [0001] The invention relates to the field of textile equipment, in particular to a drawing frame. Background technique [0002] The function of the drawing frame is to improve the internal structure of the sliver, so as to improve the uniformity of its long segments, and at the same time reduce the unevenness of the weight, make the cotton yarn in the sliver straight and parallel, reduce the hooks, make the fineness meet the requirements, and make different types or Raw materials of different qualities are mixed evenly to achieve the specified mixing ratio. [0003] When the drawing frame draws the sliver, if the draft force is insufficient, it will cause poor drafting and affect the quality of the sliver, and in the process of use, the dust and flying catkins will often cover the entire workshop. It pollutes the environment and has a bad impact on the health of operating workers. Contents of the invention [0004] The purpose of the present invention...
