Description

Technical Field

[0001] The present invention relates to the technical field of yarn processing, and in particular to a blending cotton yarn arranging device and an arranging method. Background Art

[0002] Blending cotton yarn is a kind of yarn made of mixed fibers (usually cotton and other fibers, such as polyester fibers). This kind of blending cotton yarn usually has the comfort and breathability of cotton, and at the same time has the characteristics of other fibers, such as wear resistance and easy care. Blending cotton yarn is widely used in textile manufacturing and can be used to make various clothing and household items.

[0003] Chinese Patent with publication number CN116334859B discloses a yarn arranging device for cotton yarn processing.

[0047] Example 5. As Figure 1 shown, a yarn arranging device for blended cotton yarn proposed by the present invention. Compared with Example 2, the structure of the guiding mechanism is introduced in detail in this example.

[0048] The guiding mechanism includes a guiding wheel a3, a guiding wheel b4, and a support plate 5 for installing the guiding wheel a3 and the guiding wheel b4; the support plate 5 is arranged on the workbench 1. The guiding wheel a3 and the guiding wheel b4 are rotatably connected to the support plate 5. The guiding wheel a3 and the guiding wheel b4 are in rolling contact with the blended cotton yarn 2 from below; two groups of guiding mechanisms are arranged, and the two groups of guiding mechanisms are respectively located at both ends of the workbench 1.

[0049] Example 6. As Figure 1 shown, a yarn arranging device for blended cotton yarn proposed by the present invention. Compared with Example 5, the structure of the tensioning mechanism is introduced in detail in this example.

[0050] The tensioning mechanism includes a support frame 6 arranged on the workbench 1, a telescopic device 7 vertically arranged on the support frame 6, and a mounting frame 8 arranged at the bottom of the telescopic device 7. A tension measuring roller 9 is arranged on the mounting frame 8. The tension measuring roller 9 is located between the guide wheel a 3 and the guide wheel b 4. The tension measuring roller 9 presses down the blended cotton yarn 2 between the guide wheel a 3 and the guide wheel b 4. Two groups of tensioning mechanisms are provided. During dynamic tensioning, the tension measuring roller 9 detects the contact tension between the blended cotton yarn 2 and it in real time, and sends the tension data signal to the control system. The control system dynamically controls the expansion and contraction of the telescopic device 7 according to the set tension range. Specifically, when the telescopic device 7 extends, the tension applied by the tension measuring roller 9 to the blended cotton yarn 2 is increased. On the contrary, when the telescopic device 7 contracts, the tension applied by the tension measuring roller 9 to the blended cotton yarn 2 is decreased, so as to always keep the blended cotton yarn 2 in a proper tension state.

[0051] In summary, when the present invention is in use, the blended cotton yarn 2 is conveyed and guided by two groups of guide wheels a 3 and guide wheels b 4, and the blended cotton yarn 2 passes through the water receiving tank 10 and two connecting plates 28. The two tension measuring rollers 9 dynamically tension the blended cotton yarn 2. The motor 24 drives the rotating cylinder 19 to rotate forward and backward through the driving gear 25 and the driven gear 23. The elliptical member 27, the connecting plate 28 and the elastic pressing wheel 30 drive the blended cotton yarn 2 to continuously rotate forward and backward. The water inlet pipe 12 is connected to the water supply device, and water is sprayed onto the blended cotton yarn 2 through the horizontal pipe 11 and the spray head 13. The spraying can carry away the fluff and some miscellaneous yarns attached to the surface of the blended cotton yarn 2. At the same time, the blended cotton yarn 2 is continuously rotating forward and backward. Under the action of centrifugal force, the fluff and miscellaneous yarns on the surface of the blended cotton yarn 2 will fall off or spread outwards. The surface of the blended cotton yarn 2 can be thoroughly cleaned by the cutting knife 16. And under the action of water flow, the fluff and miscellaneous yarns on the cutting knife 16 will fall onto the filter screen 17 to keep the cutting knife 16 working continuously and effectively. The water is discharged through the filter screen 17 and the drain groove 18. The fluff and miscellaneous yarns are accumulated on the filter screen 17, and the filter screen 17 can be cleaned regularly.

[0052] In the present invention, by setting the rotating mechanism to drive the blended cotton yarn 2 to continuously rotate forward and backward, under the action of centrifugal force, the fluff and miscellaneous yarns on the surface of the blended cotton yarn 2 will be thrown off or spread outwards, which is convenient for the water flow and the cutting knife 16 to complete the full cleaning of the surface of the blended cotton yarn 2. And the blended cotton yarn 2 is attached to the inner wall of the arc-shaped plate 14. The tensioning mechanism dynamically tensions the blended cotton yarn 2, so that the cutting knife 16 cannot contact the main body of the blended cotton yarn 2, and thus the blended cotton yarn 2 will not be damaged.

[0053] The embodiments of the present invention have been described in detail above with reference to the drawings, but the present invention is not limited to this. Various changes can be made without departing from the spirit of the present invention within the knowledge scope of those skilled in the art to which the present invention pertains.
