Description

[0001] This application is a divisional application. The application number of the original application is 202010980630.5, the application date is September 17, 2020, and the name of the invention is “A short-process worsted yarn production line”. Technical Field

[0002] The invention belongs to the technical field of spinning devices, and in particular relates to a short-process worsted spinning production line. Background Art

[0003] There are three major technical problems in the traditional spinning process: first, the traditional ring spinning process requires many steps, long processes, and many workers to process loose fibers into yarns, which is time-consuming and costly. High-efficiency, high-quality, short-process spinning is the basis for shortening the textile process; second, the weaving preparation and weaving process after the spinning process are long and the running speed is high, which has high requirements for yarn wear resistance, strength, hairiness and other qualities. The high hairiness of the yarn can easily cause the knitting yarn to break around the hook needle or the weaving opening to be unclear, which reduces the efficiency of weft insertion. The low wear resistance and strength of the yarn lead to a high frequency of weaving warp yarn breakage, low weaving efficiency, and poor final product quality; third, although the traditional ring spinning has high yarn cohesion and a wide range of yarn counts, the spinning is restricted by factors such as fiber length, stiffness, and fiber number. During the spinning process, the fiber internal and external transfer cohesion is insufficient, the yarn strength is low, the spinning ends are frequent, and the spinning continuity is poor. In addition, there are many problems such as long process, many steps, and low efficiency.

[0004] In order to solve the problem of long process flow of traditional ring spinning, various free-end high-speed spinning technologies have emerged. Vortex spinning is a new spinning method that uses a fixed vortex spinning tube to replace the high-speed rotating spinning cup, spinning spindle and wire ring for spinning. Since the vortex replaces the mechanical twisting and cohesion and does not require rotating parts, it has the advantages of fast speed, high output, short process flow and high production rate. However, jet vortex spinning is a free-end non-holding spinning method that uses vortex to push the free-end yarn tail to make a circular high-speed rotation and twist. It leads to insufficient holding force on the fiber during the spinning process, low degree of fiber transfer inside and outside, poor fiber bonding, and low spinning strength. Therefore, fibers with poor bonding, short length, high stiffness, and curvature and fluffy cannot be vortex-spun into yarn. Friction spinning is a spinning method with a short process, simple equipment, low speed and high yield. It uses a combination of mechanical and air to absorb and condense fibers. While absorbing and condensing fibers, the rotating dust cage friction roller uses friction to twist the whiskers into yarn. However, friction spinning yarn is a layered twisted and wrapped structure. There is a lack of internal and external transfer between the fibers inside the yarn, the cohesion between the fibers is poor, and the yarn strength is low. Therefore, when the fiber bending stiffness is large and the length is too short, the dust cage twisting cannot effectively bend, entangle and twist into yarn, and friction spinning is difficult to make yarn and the yarn quality is low. The raw material used for rotor spinning is thick fiber strips, which is different from the coarse yarn used in ring spinning. It can be directly fed into the rotor spinning machine for rotor spinning without multiple passes of delicate drafting and combing. In addition, the twisting and winding of rotor spinning are carried out separately, and the spinning speed is not affected by the yarn package. The rotor rotation speed is extremely high. Therefore, rotor spinning has the advantages of high spinning speed, large package, low cost, and low requirements for raw materials. However, the mechanism of rotor spinning is that the fibers are formed into yarns by overlapping at the free end of the yarn strip, which easily causes the fibers overlapped on the outer layer of the yarn body during the spinning process to be subject to small control force, resulting in poor control of the fiber gripping and forming by rotor spinning. It is not suitable for spinning fibers with poor cohesion, short length, high rigidity, and curvature and fluffy. In summary, compared with traditional ring spinning technology, free-end spinning greatly improves the spinning speed and shortens the process by eliminating the roving process; but free-end spinning still cannot avoid traditional processes such as carding, combing, and drawing, and the process is still relatively long. Moreover, the free-end spinning principle determines that the yarn cohesion is insufficient and the yarn strength is low. Fibers with poor cohesion, short length, and high stiffness cannot be continuously and effectively spun into high-quality free-end yarns. Summary of the invention

The stretched multiple pieces of raw materials 18 are then transported to the layered and wet-leveling mechanism through the layered guide roller 16.

[0114] As attached Figure 3 As shown, as a preferred embodiment of the present invention, the layered and wetted structure comprises:

[0115] Reservoir 42;

[0116] The water tank 22; the water tank 22 is provided with two pieces; one of the water tanks 22 is connected to the water storage tank 42 through a water supply pipe, and the other water tank 22 is connected to the water storage tank 42 through an overflow pipe; the two water tanks 22 are arranged on the rear panel;

[0118] Water transfer roller 21; the water transfer roller 21 is provided with two pieces; the two water transfer rollers 21 are respectively provided in the two water tanks 22;

[0119] The first anilox roller 20 is used to wet part of the raw material 18 transmitted from the three-roller mechanism, and the wetted raw material 18 is transported to the static elimination and broken strip temporary storage mechanism through the first anilox roller 20; the first anilox roller 20 is in contact with one of the water transfer rollers 21; the first anilox roller 20 is rotatably arranged on the rear panel;
