Definitions
- the present invention relates the field of rotor spinning in the textile industry.
- the basic principle of the rotor spinning yarn is that the sliver is fed through the trumpet and is held by feeding plate and feeding roller.
- the feeding roller rotates to feed the sliver to the carding area.
- the sliver is opened and stripped, carded separately and mixed by the carding roller, which rotates at a high speed in the carding area, so that the sliver becomes single fibers which are separated and arranged parallel to each other.
- the single fibers enter into a fiber transport channel. Under the action of air flow, the fiber flows into the rotor through the fiber transport channel. Under the centrifugal force of the rapidly rotating rotor, the fibers in the collection groove are further piled up and mixed, and then the fibers are jointed with the mother-yarn and twisted by a navel to form a yarn.
- the patent "Method and equipment for rotor spun slub yarn” (patent number CN00137211.4 ) can achieve invariable blending ratio but the linear density changes during the rotor spinning process.
- the principle of the patent is that the asynchronous motor and the stepper motor drive feeding roller through the differential, screw and worm wheel.
- the stepper motor under the control of the intelligent controller, performs the following operations: reducing from high speed to low speed; continuing to run for a period of time; accelerating to high speed; continuing to run for a period of time, and the rotor spins a segment of slub yarn.
- the patent can produce a yarn with variable densities but cannot change blending ratios of the yarn.
- the production of the yarn with the linear density and blending ratio both changed requires not only that the feeding amount of the two or more of the fed roving can be controlled separately on line, but also that the total amount of the fed roving can be controlled when the feeding amount of the roving is changed.
- the main problem of the existing rotor spinning technology which can produce the yarn having an invariable linear density and blending ratio is that it is impossible to blend two or more fibers in any proportion during the rotor spinning process.
- a device for implementing a rotor spinning method with multi-level carding and multi-component feeding includes a spinning system and a computer control system.
- the spinning system comprises a feeding and carding mechanism, a collecting and twisting mechanism, and a winding and forming mechanism.
- the device is characterized in that the feeding and carding mechanism comprises a multi-level carding roller and a combined feeding roller having three rotation freedom degrees. The speed ratio of the three combined feeding rollers with rotational freedom degree can be adjusted.
- the collecting and twisting mechanism includes a fiber transport channel, a rotor, and a yarn guider.
- the winding and forming mechanism includes a couple of guide roller and winding mechanism.
- the computer control system includes a PLC programmable controller, a servo driver and a servo motor.
- the three combined feeding rollers with rotation freedom degrees and the multi-level carding roller are driven by the servo motor.
- the combined feeding rollers with three rotational freedom degrees comprises a shaft, a bearing, a hollow shaft, a first gear, a second gear, a third gear, a washer, a first movable roller, a second movable roller, and a third movable roller.
- the first gear, the second gear, the third gear, the first movable roller, the second movable roller, and the third movable roller rotate around the same axis.
- the first to the third gears respectively drive the first to the third movable rollers.
- the multi-level carding roller comprises the first carding roller, the second carding roller and the third roller that are arranged in parallel.
- the rotation speed of the multi-level carding roller is progressively increased from the first level to the third level.
- the rotation speed of the first carding roller is 1500-3000 rpm
- the rotation speed of the second carding roller is 3000-6000 rpm
- the rotation speed of the third carding roller is 6000-12000 rpm.
- the density of carding needles of the multi-level carding roller progressively increases from the first carding roller to the third carding roller.
- the other objective of the present invention is to provide a rotor spinning method using the above device.
- the method includes feeding, carding, collecting and twisting, guide and winding.
- the method is characterized in that combined feeding rollers with three rotational freedom degrees are used in the fiber feeding to feed the fiber into the carding area asynchronously, and multi-level carding roller is used in the carding process.
- three slivers (or three different raw material slivers, or three kinds of colored slivers, hereinafter referred to as three components) can be asynchronously fed into the rotor spinning and carding area through the combined feeding rollers.
- the three slivers After opening, carding, orienting, separating and mixing, by the multi-level carding roller, the three slivers are gradually combed into bundle fibers and further combed into single fibers. Under the action of centrifugal force and air flow, a continuous flow comprised by single fibers released and transferred from the carding roller enters into the rotor rotating at a high speed.
- the fiber flow In the rotor, the fiber flow, under the centrifugal force, is collected together into a sliver again, and then twisted by the navel, and then guided by the guide roller to form the rotor spinning yarn.
- the servo driving system is controlled by a computer program to feed three slivers asynchronously to the carding area by feeding rollers having three freedom degrees. By controlling the feeding amount and feeding ratio of the three feeding rollers, it is possible to dynamically configure the final yarn density of the rotor spinning and the blending ratio of the three components to produce slub yarn, segment-color yarn, segment-color slub yarn, and mixture yarn.
- the speed of the first carding roller is low, so that it is ensured that when the plurality of the slivers with great difference are fed, the total number of carding fibers of each sliver carded by the carding roller are within a reasonable range, thereby reducing damage to the fiber.
- the speed of the second carding roller is higher than that of the first carding roller. After being carded by the second carding roller, the longitudinal orientation of the fiber is optimized, horizontal transfer mixing of the fiber is further optimized.
- the third carding roller is a high-speed carding roller. The fiber, after being carded by the third carding roller, obtains not only a better carding and transfer, but also the transport speed is improved, thereby meeting the requirement of centrifugal force for entering the fiber transport channel.
- the fiber can smoothly and orderly go into the rotor to form yarns.
- the large-scale drafting function where the slivers are combed into web, which is then combed into bundles of fibers, which are then separated into as single fibers is successfully completed, which enhances the function of the carding area of the rotor spinning, providing flexibility, high efficiency, and high yield.
- the present invention constructs the corresponding mathematical model of spinning and the algorithm of the program.
- the mechatronic servo control system Through the mechatronic servo control system, the random control of the linear density and blending ratio of the rotor spinning yarn are achieved.
- the three kinds of spinning yarns are shown as following:
- Subscripts 1, 2, 3, represent component A, component B, component C, respectively.
- the fiber holding time of each component is also greatly different.
- the rotation speed of the single carding roller is high. Therefore, when there is a significant difference in feeding amount, the number of times that a fiber of the three slivers is carded will be significantly different, and the more the fiber experiences carding, larger will be the damage to this fiber.
- the present invention adopts the form of three-level carding rollers, that is, the first carding roller, the second carding roller and the third carding roller.
- the large-scale drafting function where the slivers are combed into web, which is then combed into fiber bundles which are separated into single fibers, is successful completed, which enhances the function of the carding area of the rotor spinning, meets the special requirements for the carding of multiple slivers asynchronously feeding into the rotor spun unit.
- the effects of flexibility, high efficiency, and high yield are realized.

- V 01 , V 02 and V 03 the blending ratio (color mixing ratio) of different fibers (different colors) in the yarn can be changed under the condition that V 0 is kept invariable, so that k 1 , k 2 and k 3 are changed between 0 - 100%.
- the minimum increment of the color mixing ratio is 0.1, wherein one of the color schemes is as follows: Table 1 color scheme color A color mixing ratio k 1 color A color mixing ratio k 2 color A color mixing ratio k 3 Color Code monochrome Color A 1 0 0 1 Color B 0 1 0 2 Color C 0 0 1 3 Double mixed color AB 0.1 0.9 0 4 0.2 0.8 0 5 0.3 0.7 0 6 0.4 0.6 0 7 0.5 0.5 0 8 0.6 0.4 0 9 0.7 0.3 0 10 0.8 0.2 0 11 0.9 0.1 0 12 Double mixed color AB 0.1 0 0.9 13 0.2 0 0.8 14 0.3 0 0.7 15 0.4 0 0.6 16 0.5 0 0.5 17 0.6 0 0.4 18 0.7 0 0.3 19 0.8 0 0.2 20 0.9 0 0.1 21 Double mixed color AB 0 0.1 0.9 22 0 0.2 0.8 23 0 0.3 0.7 24 0
- k 1 +k 2 +k 3 100% can have numerous combinations. Based on the three primary colors (three kinds of color slivers) by coupling and drafting, color alternating, gradient color matching, twisting and mixture, numerous color schemes can be formed. In addition, it is possible to form a segment-color yarn having a variety of color distribution in the yarn.
