Problems solved by technology
In order to solve the problem of low drafting capacity in the rear area, it was disclosed in the Chinese patents "Drawing Device for High Count Worsted Frame" (No. 96107383) and "Four-Apron Drafting Mechanism for Spinning Frame" (No. 012439010) A three-roller three-apron and three-roller four-apron drafting mechanism is developed, which better solves the problem of weak drafting capacity in the rear area of the three-roller drafting mechanism, so that the total drafting ratio can be increased to 100
However, because it adopts a three-roller form, that is, there are only two continuous draft zones, the increase in draft ratio is limited

Embodiment Construction
[0010] Depend on figure 1 , figure 2 and image 3 As shown, a four-roller dual-motor drive spinning device includes a drafting system. The drafting system includes a pair of rear rollers, a pair of middle and rear rollers, a pair of middle front rollers, and a pair of front rollers. The pair of rear rollers includes rear bottom rollers 1 and The rear top rubber roller 2, the middle rear roller pair includes the middle rear bottom roller 3 and the middle rear upper rubber roller 4, the middle front roller pair includes the middle front bottom roller 5 and the middle front upper rubber roller 6, and the front roller pair includes the front bottom roller 7 And front upper rubber roller 8, rear lower Rolla , middle and rear bottom rollers, middle and front bottom rollers, and front bottom rollers have the same structure, and the rear bottom rollers, middle and rear bottom rollers, middle and front bottom rollers, and front bottom rollers include roller shaft 9, which is a soli...

The invention discloses a quadriserial roller dual-motor drive spinning device and a spinning method. A drafting system adopts quadriserial rollers and is of a three-drafting structure comprising a rear drafting zone, a middle drafting zone and a front drafting zone; a drive control system consisting of two motors and two gear sets is adopted for the quadriserial rollers; selected two columns including front lower rollers are directly driven by adopting two motors to drive; the rest two columns of rollers are in driving connection with the two columns of rollers driven by the motors through two gear sets, so that the draft ratio of the rest one drafting zone is adjustable under the condition that the draft ratios of any two drafting zones in the three drafting zones are fixed, or specificdraft distribution of the two drafting zones is adjustable under the conditions that the draft ratio of any one drafting zone in the three drafting zones is fixed and the total draft ratio of the resttwo drafting zones is fixed, optimized design of a drafting system in the spinning process is realized, further the raw material spinnable property of a spinning frame is improved and the comprehensive quality of resultant yarns is improved.
Description
technical field [0001] The invention relates to the new technical field of ring spinning, in particular to a four-roller double-motor driven spinning device and a spinning method. Background technique [0002] The drafting system is an important part of the spinning frame, and its performance directly affects the yarn quality. At present, the common spinning frame adopts the three-roller drafting form, including the common three-roller double-apron structure and the three-roller four-apron structure that can achieve 80-100 times larger draft. The ordinary three-roller double-apron structure is divided into two drafting areas: the front drafting area and the rear drafting area, and the rear area only uses simple rollers for drafting, so the friction force circle in the middle is relatively weak, and the draft ratio is generally less than 1.4 times, which is unfavorable to increase the total draft ratio of the spinning frame, so the total draft ratio is between 20 and 50. In...
