Embodiment 1

[0036] Such as figure 1 Shown is a schematic diagram of the structure of a traditional pull-cutting roller set, such as figure 2 , 3 As shown, a low-strength fiber drafting and cutting device includes a drafting device 4 with a feeding end 2 and a discharging end 3 composed of multiple sets of drafting rollers 1, each of which A drafting zone 5 is formed between 1 and each set of drafting rollers 1 is composed of a pair of meshing drafting rollers 6 and a pair of drafting rollers 7 respectively. The drafting transition zone 8 is formed between the cutting roller 7 and the drafting roller 6. The drafting roller 6 and the drafting roller 7 are composed of two roller bodies 9 that mesh with each other. The drafting in each drafting zone 5 The horizontal distance between the roller 6 and the pulling roller 7 along the axis of the roller body 9 gradually increases or gradually decreases. In this embodiment, in order to realize that the horizontal distance between the draft roller 6...

Embodiment 2

[0043] The same parts of this embodiment and Embodiment 1 will not be repeated here, and the difference lies in: Figure 4 As shown, the longitudinal cross-sectional shape of the roller body 15 of the pulling roller 14 in the axial direction is set to a trapezoidal structure. The roller bodies 15 of the adjacent pulling rollers 14 are parallel to each other and are installed oppositely.

Embodiment 3

[0045] The same parts of this embodiment and Embodiment 1 will not be repeated here, and the difference lies in: Figure 5 As shown, the horizontal distance between the draft roller 17 and the draft roller 18 in each of the draft cutting zones 16 along the axis of the roller body 19 changes alternately. The longitudinal cross-sectional shape of the roller body 19 of the pulling roller 18 in the axial direction is configured as a wave structure.

Abstract

The invention discloses a low-strength fiber stretch-breaking and slivering device. The low-strength fiber stretch-breaking and slivering device comprises a stretch-breaking device which is composed of multiple sets of stretch-breaking roller set and provided with a feeding end and a discharging end, a stretch-breaking area is formed between each set of the stretch-breaking roller set, each set of the stretch-breaking roller set is composed of a pair of stretching rollers and a pair of stretch-breaking rollers which are meshed with each other respectively, a stretch-breaking transition area is formed by the stretching roller and the stretch-breaking roller which are located between adjacent stretch-breaking roller sets, the stretching roller and the stretch-breaking roller are both composed of two roller bodies, and the size of the horizontal distance between the stretching roller and the stretch-breaking roller in the axial direction of the roller body in each stretch-breaking area is changeable. Through arranging tapered or trapezoid structure, the tractive force of the stretch-breaking areas is greatly reduced, the diameters of the stretch-breaking rollers are decreased, the distance of the stretch-breaking areas formed by the stretch-breaking roller sets is shortened, the distance between the stretching roller and the stretch-breaking roller can be set to be small enough, stretch-breaking can be conducted on short fiber with smaller cotton fiber level, and the production efficiency is greatly improved. The low-strength fiber stretch-breaking and slivering device has the advantages that the structure is simple and compact, the occupied area is small, the cost is low, and popularization and application are applicable.

Description

Technical field [0001] The invention belongs to the technical field of textile machinery, and particularly relates to a low-strength fiber drafting and cutting device. Background technique [0002] As we all know, the existing spinning process generally involves fiber bundles making slivers, blending, and then obtaining coarse fibers with corresponding fiber ratios. After further processing, fine fibers can be used as spinning yarns. There are usually two ways to make fiber bundles. That is to say, cutting and pulling, equal length fibers are usually made by special cutters, and the length of the fibers is equal. There are cotton staple fibers and medium-length fibers. Cotton short fibers have various specifications of 33mm, 35mm, 38mm, 41mm; medium-length chemical fibers have various specifications of 45mm, 51mm, 60mm, 65mm. The different-length fibers are made by the draw-cutting method. Because the products processed by the different-length fibers have a woolen fabric style, ...
