Short-process fine spinning production line

Abstract

The invention is suitable for the technical field of spinning devices, and provides a short-process fine spinning production line. The production line is composed of a liftable air swelling shaft mechanism, a slitting row cutter mechanism, a three-roller mechanism, a layered uniform wetting mechanism, a static electricity eliminating and broken sliver temporary storage mechanism, a yarn leading panel and yarn passing wheel mechanism, a ring spindle and tangential belt transmission mechanism, a steel collar and package forming mechanism and a PLC mechanism. According to the invention, by improving a ring spinning technology, especially adding automatic control technologies of slip frequency, tension and the like, the production process is greatly shortened, the yield is greatly increased while the quality is improved, and the energy-saving effect is remarkable. When being in actual use, the short-process fine spinning production line can be turned on and off at any time by a single person, the end breakage rate of startup and shutdown is almost zero, technicians are not needed, basic automatic production is achieved except reel change and thread connection, all intermediate procedures and equipment of fine spinning are saved, and the per capita productivity and the yield per unit area are greatly improved while the yarn quality is improved.

Description

technical field [0001] The invention belongs to the technical field of spinning devices, in particular to a short-flow worsted yarn production line. Background technique [0002] In the traditional spinning process, there are three major technical problems: First, the traditional ring spinning requires many procedures, long process, labor intensive, time-consuming and high cost to process bulk fiber into yarn. High-efficiency and short-process spinning is the solution to shorten The basis of the textile process; second, the weaving preparation and weaving process after the spinning and spun yarn process are long and the operating speed is high, and the quality requirements for yarn wear resistance, strength, hairiness, etc. are high, and the yarn hairiness is easy to cause knitting yarn Broken needles or unclear weaving openings reduce weft insertion efficiency, yarn wear resistance and low strength lead to high frequency of weaving warp yarn breakage, low weaving efficiency...

Problems solved by technology

[0002] In the traditional spinning process, there are three major technical problems: First, the traditional ring spinning requires many procedures, long process, labor intensive, time-consuming and high cost to process bulk fiber into yarn. High-efficiency and short-process spinning is the solution to shorten The basis of the textile process; second, the weaving preparation and weaving process after the spinning and spun yarn process are long and the operating speed is high, and the quality requirements for yarn wear resistance, strength, hairiness, etc. are high, and the yarn hairiness is easy to cause knitting yarn Broken hook needles or unclear weaving openings reduce weft insertion efficiency, yarn wear resistance and low strength lead to high frequency of weaving warp yarn breakage, low weaving efficiency, and poor quality of final products; thirdly, although traditional ring spinning The yarn cohesion is high, and the range of spinning counts is wide, but the spinning is restricted by factors such as fiber length, stiffness, and fiber number. Frequent spinning, poor spinning continuity, and many problems such as long process, many processes, and low efficiency

However, the mechanism of rotor spinning is that the fibers are overlapped at the free end of the sliver to form a yarn, which may easily cause the fibers overlapped on the outer layer of the yarn to be less controlled during the spinning process, resulting in the rotor spinning having a greater impact on the fibers. Poor forming control ability, not suitable for fiber spinning with poor cohesion, short length, high rigidity, bending and fluffy

To sum up, compared with the traditional ring spinning technology, each open-end spinning has greatly improved the spinning speed, and shortened the process by canceling the roving process; but the open-end spinning still cannot avoid carding, combing , drawing and other traditional processes, the process is still long, and the principle of free-end yarn formation determines that the yarn cohesion is insufficient, the yarn strength is low, and the fibers with poor cohesion, short length, and high stiffness cannot be continuously and effectively freed with high quality. end spinning
