Embodiment 1

[0027] A kind of ultra-short fiber spinning device, such as figure 1 As shown, it comprises front roller 3, middle roller 2, back roller 1, output roller 4, annular winding device 6, spinning frame twisting mechanism 5, and annular winding device 6 consists of filament package 12, tension device 7, The filament package fixing mechanism 10, the filament winding shaft 11, the winding shaft transmission mechanism 8 and the winding shaft transmission belt 9 are composed. The front roller 3, the middle roller 2, and the rear roller 1 are all a pair and are arranged sequentially from front to back, and the front roller 3 front is successively equipped with an annular winding device 6 and a pair of output rollers 4. Such as figure 2 , image 3 As shown, the annular winding device 6 includes three parts: the first part is a filament winding device, which is composed of a filament winding shaft 11, a winding shaft transmission mechanism 8 and a winding shaft transmission belt 9, and...

Embodiment 2

[0036] The draft ratio in the region between the delivery roller 4 and the front roller 3 of the present invention is 0.99. The filament winding shaft 11 of the filament winding device has a hollow structure with a thickness of 7 mm, an inner diameter D1 of 8 mm, an outer diameter D2 of 15 mm, and a length H1 of 110 mm. One end of the filament winding shaft 11 is installed on the winding shaft transmission mechanism 8, and the other end of the filament winding shaft 11 passes through the filament package fixing mechanism 10 and the filament package 12 in turn, and is fixed with the tension device 7 connect. The winding shaft transmission mechanism 8 is a bearing structure, and the winding shaft transmission mechanism 8 is fixed on the spinning machine body through its bearing inner ring, and its bearing outer ring is used to fix the filament winding shaft 11, and the winding shaft transmission mechanism 8 The bearing width H2 is 15mm, and the winding shaft transmission mechan...

Abstract

The invention discloses an ultra-short fiber spinning device which comprises front rollers, middle rollers, rear rollers, a spinning frame twisting mechanism, output rollers and an annular winding device. The front rollers, the middle rollers and the rear rollers are respectively in pairs and sequentially arranged from front to back, the annular winding device and a pair of the output rollers are sequentially arranged in front of the front rollers, the annular winding device comprises a filament winding device, the outside of the filament winding device is provided with a filament winding mechanism, the head end of the filament winding device is provided with a tensioning device, the filament winding device comprises a filament winding shaft, a winding shaft transmission mechanism and a winding shaft transmission belt, the filament winding mechanism is composed of a filament package and a filament package fixing mechanism, and the filament package fixing mechanism is arranged between the filament package and the winding shaft transmission mechanism. The ultra-short fiber spinning device has the advantages that noil fiber strands can be directly twisted to form yarns under the wrapping function of filaments, and accordingly the utilization rate of noil is improved.

Description

technical field [0001] The present invention relates to an ultra-short fiber spinning method and its device, in particular to a refitting method and device for spinning ultra-short fiber on traditional ring spinning equipment for the purpose of improving the utilization rate of noil, belonging to the textile industry. technology field. Background technique [0002] Noil is the short fluff and impurities separated from the cotton blower, carding machine or combing machine, mainly including broken seeds, ground flowers, car belly flowers, cut flowers and combed noil. In China, fibers with a length of less than 16mm are usually considered as short staples, while internationally, cotton fibers with a length of less than 12.7mm (0.5 inches) are considered short staples. AFis, HVI and PREMIER fiber testers all define the linters below 12.7mm. Because the short staples are short and affect the uniformity of the overall length of the cotton fibers, they generally cannot be used fo...
