Description

Technical Field

[0001] The utility model relates to the field of textiles, in particular to the technical field of long-fiber and short-fiber composites, and specifically refers to a production system for core-wrapped ring spinning. Background Art

[0002] Core-spun wrapped composite yarn is a new type of yarn developed to enhance the physical properties of military training uniforms. This production technology involves simultaneously feeding two parallel unwound filaments and a staple fiber into the yarn drafting and twisting mechanism. One filament is positioned in the center of the staple fiber strands, while the other wraps around the yarn surface. This creates a stable yarn structure that improves physical properties such as tear strength and abrasion resistance. Due to the large and stable demand for military products, as well as the potential civilian market, many textile companies have increased their research and investment in related production technologies and equipment.

[0003] Traditional core-spun, wrapped filament staple composite yarns typically use a feeding method that uses twice as many filaments as the roving. This method requires high equipment modification investment, making it unsuitable for large-scale transformation. Limited by the space above the spinning frame, it can only use a small amount of filament, resulting in short production cycles and frequent yarn laying and changing. Furthermore, since yarn laying and changing are performed at high altitude, there are certain safety risks, and it is difficult to organize a large number of people to operate the machine together, resulting in low production efficiency.

[0004] At the same time, the utility model CN107385613A describes a core-wrapped filament staple composite yarn and a production device that adopts a method of passive unwinding of double filaments in a spandex paper tube package, which requires the use of a wire guide roller as support; due to the small capacity of the paper tube, the wire needs to be changed frequently; the precision of the winding equipment is required to be high, and the investment in purchasing the equipment is large; the filament tension varies greatly during production, and the unwinding is unstable; this patented method has a low spinning speed and is not conducive to large-scale production.

After the winding of the winding machine is completed, the roving tube is placed on the spinning frame. Due to the setting of double filament winding on the roving tube, the root ratio of filament to staple fiber is 2:1, so the staple roving wound with staple fiber and the double filament yarn wound with staple fiber are both The roving bobbins are unwound and spun at the same time, which facilitates the simultaneous replacement of double filaments and staple fibers. The double filaments are divided into two single filaments after passing through the tension device. The two single filaments pass around the two splitting rods respectively, thereby realizing the forced separation of the two single filaments. The two single filaments enter the double-groove guide wheel together and are fed into the front jaw of the spinning frame; at the same time, the staple fibers are unwound through the inner yarn guide rod and fed into the drafting area of ​​the spinning frame, and are output together with the two separated filaments at the front jaw, and are twisted and wound into cop yarn on the steel collar through the yarn guide hook.

[0029] In order to clearly illustrate the technical features of this solution, this solution is described below through specific implementation methods.

[0030] Refer to the attached Figure 1-5 The utility model discloses a production system for core-wrapped ring spinning, which includes a winding machine and a spinning frame. The winding machine winds two single filaments in parallel on a roving tube, and the spinning frame uses short fiber roving and double filaments as spinning raw materials to realize the production of core-wrapped structured yarn.

[0031] The winding machine includes a frame 7, on which several spindles 5 are provided. A high-strength paper tube is sleeved on the roving tube to balance the additional stress of the filament and avoid damaging the roving tube. The roving tube is then sleeved on the spindle 5. The frame 7 is also provided with a wire guide 3 located on one side of the roving tube. The wire guide 3 is connected to the winding machine lifting mechanism through a connecting rod. A length meter 8 is provided below the wire guide 3. The length meter 8 includes a length measuring wheel 9, a wire cutter 10, a tension device, a wire guide hook 12, and a wire guide hook 1 arranged in sequence from top to bottom. 2 is provided with a wire detector 13 and a wire guide porcelain eyelet 14 below. A bracket 16 for supporting a wire drum 15 is provided below the wire guide porcelain eyelet 14. The bracket 16 includes an upper supporting plate and a lower supporting plate. The two wire drums 15 corresponding to the same roving bobbin are longitudinally staggered and respectively arranged on the upper supporting plate and the lower supporting plate. The upper supporting plate is provided with a wire guide porcelain eyelet 14 for the filaments of the lower wire drum 15 to pass through. The wire guide porcelain eyelet 14 is located directly above the lower wire drum 15. The two adjacent wire drums 15 on the same side are respectively arranged on the upper supporting plate and the lower supporting plate.

[0032] The spinning frame includes a bracket, on which are two cradles 22 which are arranged horizontally and symmetrically. One cradle 22 corresponds to two short fibers, two double filaments and two cops, that is, two short fiber rovings 19 and two roving tubes 1. A double-groove guide wheel 23 is connected to the upper axis of the cradle 22. A yarn guide hook 24, a steel collar 25 and a cop 26 are arranged in sequence below the double-groove guide wheel 23. The bracket is also provided with a cross arm 20 located above the cradle 22. The cross arm 20 is provided with a yarn guide rod 27 for the short fibers to pass around, and two staggered wire dividing rods 21 for two single filaments to pass around respectively. The two wire dividing rods are arranged along the extension direction of the cross arm.

[0033] The short-fiber roving 19 and the roving tube 1 are connected to the bracket and are located above the defilament rod 21.

[0035] The method for using the core-wrapped ring spinning production system comprises the following steps:

[0036] a. When the winding machine is in use, the filaments on the lower bobbin pass through the corresponding wire guide porcelain eye on the upper support plate, and then pass through the wire guide porcelain eye, wire detector, yarn guide hook, tension device, wire cutter, length measuring wheel, and wire guide in sequence before being wound on the high-strength paper tube. When the winding machine is started, the tangential belt drives the spindle to rotate at high speed. Driven by the lifting mechanism of the winding machine, the wire guide rises and falls according to the set forming requirements. The two filaments are wound together on the high-strength paper tube, thereby forming a double filament of the roving bobbin package, thereby realizing winding two single filaments and a double filament on the roving tube. The roving tube is covered with a high-strength paper tube, which can balance the stress of the filaments on the roving tube and avoid damage to the roving tube.

[0037] b. On the spinning frame, hang the same number of roving tubes and short fiber roving on the spindle of the spinning frame, and the double filaments are unwound around the upper guide rod and separated after passing through the tension device. The two single filaments pass through the inner sides of the two dividing rods respectively, so as to realize the forced separation of the two single filaments; the separated single filaments pass through the two wire grooves of the double-groove guide wheel respectively and are fed into the front jaw of the spinning frame; at the same time, the roving is unwound through the inner yarn guide rod and fed into the drafting area of ​​the spinning frame, and is output together with the two separated filaments at the front jaw, and is twisted and wound into a tube yarn on the steel collar through the yarn guide hook. The tension device has tension setting and tension compensation functions. The tension value attached to the filament can be set according to different requirements during production. The tension compensation function can make the filament tension as close to the set value as possible.

[0038] In particular, the lifting mechanism, the wire guide porcelain eye 14, the wire detector 13, the yarn guide hook 24, the tension device, the wire cutter 10, the length measuring wheel 9, the wire guide 3, the dragon belt 6, the spindle 5, the double-groove wire guide wheel 23, the yarn guide hook 24, the steel collar 25, and the bobbin 26 are all prior art.
