Problems solved by technology

The applicant has also applied for the invention patent of the "roller needle-plate mixed type ramie stretch-cut spinning equipment" whose publication number is CN1760416 and the utility model of the "roller pin-roller mixed type ramie stretch-cut spinning equipment" whose publication number is CN2856073. Patent, it is planned to install a needle plate or needle roller device in the fourth stretching zone of the ramie stretching machine to achieve the purpose of reducing doubling, because the degree of looseness and separation of ramie dry hemp in the fourth stretching zone is not ideal , although it has the splitting and carding function of the needle plate or needle roller, the problem of doubling the stretched strips has not been well solved

Abstract

The invention provides a preposing needle roller combined ramie converting spinning device which is characterized by consisting of a roller type converting device, an extraction roller device and a needle roller device that are respectively fixed on a stander; wherein, the needle roller device is arranged between the roller type converting device and the extraction roller device. As the existing two working procedures which are opening and rippling are replaced by the preposing needle roller combined ramie converting spinning device, fiber damage caused by severe action of sawteeth on fiber is avoided, and ramie grains and overcut fiber can be effectively reduced. Furthermore, the needle roller device is adopted to effectively solve the problem that more paralled yarn is increased due to only roller converting is utilized, and paralled yarn can be more effectively reduced by arranging the needle roller device at a fourth converting area instead of a strip-producing area, thus creatinggood condition for improving the quality of the ramie products.

Description

technical field [0001] The invention relates to a front needle-roller-roller hybrid ramie stretch-cut spinning device, which belongs to the field of textile engineering. Background technique [0002] The traditional ramie spinning process is: dry hemp → soft hemp process → opening process → carding process → pre-combing process (2 steps) → combing process → needle carding process (3-4 steps) → roving process → spun yarn process. [0003] In the traditional ramie spinning process, the two kinds of equipment used in the opening process and the carding process mainly use its sawtooth and other parts to strongly comb the ramie fibers, causing damage and entanglement of the ramie fibers, resulting in ramie fibers The short fleece in the grain increases, and the hemp grains increase sharply. And the problem of the ultra-long fiber and fiber length unevenness that ramie itself exists still can't solve well. In response to these problems, the stretch-cut spinning process of ramie...
