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 a 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. With the centrifugal force of the rapidly rotating rotor, the fibers in the 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" 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.
  • D1 CN103938322 A is to provide a rotor spun yarn blending method, using the same or different, and two or more fiber strands are fed at the same feed speed or a different location in the same straight line density carding and twisting means, by opening, carding, mixed, agglomerated with twisted, made of color segments or rotor spinning yarn segment color mixing.
  • D2 CN 104790074 A is to provide a synchronous five different components drawn yarn count line dynamic regulation and regulation of the blending ratio, colorful and multicolored little slub yarns spun.
  • D3 EP 1564318 A2 relates to the method of sliver feeding in production of fancy yarn on spindle-less rotor machines with sliver feeding by a feed roller to the stripping roller, stripping individual fibres from the sliver that are consequently used at the spinning rotor for yarn spinning plus spinning units for this method performance.
  • D4 EP 1352998 A2 relates to a feed roller for a spinning apparatus with a work area for providing a first textile material for a spinning element as well as an opening device for a spinning apparatus having a rotatably mounted in a housing opening roller and a feed device for feeding a sliver to the opening roller.
  • a device for implementing a rotor spinning method with three-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 mechanism.
  • the device is characterized in that the feeding and carding mechanism comprises five combined feeding rollers with rotational freedom degrees, and a three-level carding roller. The speed ratio of the five combined feeding rollers with rotational freedom degree can be adjusted.
  • the collecting and twisting mechanism include a fiber transport channel, a rotor, and a yarn guider.
  • the winding mechanism includes a couple of guide rollers and a winding mechanism.
  • the computer control system includes a PLC programmable controller, a servo driver, and a servo motor.
  • the five combined feeding rollers with rotational freedom degrees and the three-level carding roller are driven by the servo motor.
  • the combined feeding rollers with five rotational freedom degrees comprises a shaft, a bearing, a hollow shaft, a first gear, a second gear, a third gear, a fourth gear, a fifth gear, a washer, a first movable roller, a second movable roller, a third movable roller, a fourth movable roller, and a fifth movable roller.
  • the first to fifth gears and the first to fifth movable rollers rotate around the same axis.
  • the first to fifth gears respectively drive the first to fifth movable rollers.
  • the three-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 three-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 three-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 cotton feeding, carding, collecting and twisting, guide and winding.
  • the method is characterized in that combined feeding rollers with five rotational freedom degrees are used in the fiber feeding to feed the fiber into the carding area asynchronously, and three-level carding roller is used in the carding process.
  • five slivers (or five different raw material slivers, or five kinds of colored slivers, hereinafter referred to as five components) can be asynchronously fed into the rotor spinning and carding area through the combined feeding rollers.
  • the five slivers After opening, carding, orienting, separating and mixing by the three-level carding roller, the five 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 five slivers asynchronously to the carding area by feeding rollers having five freedom degrees. By controlling the feeding amount and feeding ratio of the five feeding rollers, it is possible to dynamically configure the final yarn density of the rotor spinning and the blending ratio of the five 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 multi-level stripping, opening, cleaning, carding, separating and transferring the large-scale drafting function where the slivers are combed into web, which is then combed into bundles of fibers, which are then separated 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. Through the mechatronic servo control system, the random control of the linear density and blending ratio of the rotor spinning yarn are achieved.
  • the four kinds of spinning yarns are shown as following:
  • Subscripts 1, 2, 3, 4, 5 represent component A, component B, component C, component D, component E, 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 five 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.
