Embodiment 1

[0117] Such as Figure 1-3 As shown, a kind of four-channel hollow spindle fancy yarn forming device provided by the present embodiment includes: for the first component yarn Y 1 First channel A through 1 B 1 C 1 D. 1 D. 2 E. For the second component yarn Y 2 Second channel A through 2 B 2 C 2 D. 1 D. 2 E. For the third component yarn Y 3 Passed third channel A 3 B 3 C 3 D. 1 D. 2 E. For the fourth component yarn X 1 The fourth channel through R 1 C 2 D. 1 D. 2 e.

[0118] The first channel is sequentially provided with the first rear roller 41, the first middle roller 61, the first front roller 71, and the first twisting point D 1 and the second twist point D 2 ; The second passage is provided with the second back roller 42, the second middle roller 62, the second front roller 72, the first twisting point D in sequence 1 and the second twist point D 2 ; The third passage is provided with the third rear roller 43, the third middle roller 63, the third ...

Embodiment 2

[0139] In addition, this embodiment also discloses a fancy yarn forming method using the above-mentioned four-channel hollow spindle fancy yarn forming device.

[0140] 1. Spinning of decorative thread, core thread, and solid thread twisted into hollow spindle fancy yarn in one step

[0141] In the twisting triangle area of ​​the first twisting point, three coaxial front rollers with the same outer diameter and different rotating speeds respectively output three paths of untwisted yarn and one path of spun yarn (or filament). combined to form the main body of the fancy yarn; at the second twisting point, the spun yarn (or filament) output from the fifth channel is covered and twisted with the main body of the formed fancy yarn to form a fancy yarn to realize decorative lines , core thread, fixed thread one-step hollow spindle fancy yarn spinning.

[0142] 2. Spinning of fancy yarn with winding structure changing online

[0143] By regulating the speeds of the rear rollers an...

Embodiment 3

[0201] The structure of this embodiment is basically the same as that of Embodiment 1, the difference is that:

[0202] Such as Figure 5 As shown, the control system also includes a first comparison module, the first comparison module is respectively connected with the first sensor, the second sensor, the third sensor and the controller, and the first comparison module is used to monitor the middle roller shaft 6 and the rear roller shaft 4 and the speed ratio between the auxiliary shafts, the controller regulates the speed of the middle roller shaft 6, the rear roller shaft 4 and / or the auxiliary shaft according to the numerical value fed back by the first comparison module, and then regulates the first component yarn, the second component yarn and the second component yarn The blending ratio of the three-component yarn.

[0203] In order to realize the adjustment of the yarn blending ratio accurately and quickly, the present invention directly adjusts and controls accordin...

Abstract

The invention provides a four-channel hollow ingot fancy yarn forming device and method. The yarn forming device comprises a first channel, a second channel, a third channel and a fourth channel. First and second twisting points are arranged on the channel; the first to fourth components are inter-twisted to form a fancy yarn main body through the first twisting points; a hollow ingot is arrangedat the second twisting points, and the fifth component on the hollow ingot is jointed with the fancy yarn main body to wrap and twist the fancy yarn main body. The device spins the fancy yarn in one step by implementing alternating drawing, inter-twisting and wrapping processes through a one-step method. By regulating the speed of feeding the decorative yarn and the core yarn synergically into thetwisting points, the linear density and the blending ratio of the decorative yarn, the twisting degree of the core yarn and switching of the corn yarn and the decorative yarn and the like, online changes of colors and shapes of bamboo joints, paunches, knots, rings and pigtails of the fancy yarn are achieved, so that the novel variety of the fancy yarn is expanded.

Description

technical field [0001] The invention relates to the technical field of spinning in textile engineering, in particular to a four-channel hollow spindle fancy yarn forming device and method. Background technique [0002] The production of fancy yarns on hollow spindle spinning machines usually adopts a two-step method. In the first step, the core yarn, decorative yarn and fixed yarn are spun separately; in the second step, the core yarn fed at different speeds is False-twisting of the decorative yarn, through the overfeeding of the decorative yarn to the core yarn, the decorative yarn is twisted on the core yarn to form knots, circles, braids and other patterns, and then the fixed yarn unwound from the hollow spindle is used to wrap the The formed flower knot is fixed to form a hollow spindle fancy yarn. The main problems in the production of fancy yarns on hollow spindle spinning machines are as follows: [0003] 1) The color change of the fancy yarn cannot be controlled wh...
