Description

Technical Field

[0001] The utility model relates to a yarn-finding device, in particular to a yarn-finding device used in a vortex spinning process, and belongs to the technical field of equipment in the vortex spinning process. Background Art

[0002] Vortex spinning is a new spinning method characterized by high efficiency, environmental friendliness, and intelligence. The principles behind this method are as follows: After being drawn, the slivers are fed to the drafting device. After being stretched by the top rollers and aprons in the drafting device, the slivers are fed into the spinning box, where process air envelops the stretched slivers, forming yarn. The yarn is ejected from the bottom outlet of the spinning box, impacting an inclined baffle, and then enters the yarn suction pipe for yarn finding and piecing.

[0003] The piecing process is as follows: the spindle ejects the yarn, then strikes the baffle, and then returns to the yarn suction tube. However, during this process, the yarn often strikes the baffle, changing its path and failing to accurately enter the yarn suction tube. Furthermore, the spin box outlet is located on the side, and when the yarn is ejected, it is ejected sideways, resulting in a low yarn piecing success rate, which seriously affects production efficiency and quality.

[0004] Although the prior art "CN103213876A Automatic yarn catching yarn magazine for automatic winding machine" discloses: an inverted "J"-shaped suction tube and a yarn catching bell mouth, it mainly solves the problem of automatic yarn catching accuracy of the yarn magazine of the winding machine; "CN100532663C Automatic yarn finding device for rotor spinning machine", but it mainly solves the shortcomings of manual splicing and semi-automatic splicing technology when splicing broken yarn.

[0005] Therefore, a yarn finding device is needed that cooperates with the vortex spinning process, ensures high yarn finding accuracy in the yarn joint process, and is adaptable to different spinning boxes. Summary of the Invention

[0006] To address the existing technical issues, a yarn-finding device for vortex spinning is proposed. This technical solution, by providing a trumpet-shaped yarn guide tube and a moving assembly on the yarn suction tube, ensures that the yarn ejected from the spin box outlet is guided into the yarn suction tube in an orderly, stable, and controllable manner. This ensures high yarn-finding accuracy during the yarn piecing process, thereby improving the quality and efficiency of the piecing process.

[0007] In order to achieve the above technical objectives, the following technical solutions are proposed:

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present application will be described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0034] Embodiment 1

[0035] A yarn searching device for a vortex spinning spinning process, as shown in Figure 1 is arranged at the outlet of the spinning box 1, and the position behind the outlet of the spinning box 1 is provided with a yarn suction pipe 9. The yarn searching device comprises a moving assembly and a horn-shaped guide tube 8. The moving assembly comprises a horn-shaped guide tube mounting frame 6 and a cylinder 5 for driving the horn-shaped guide tube mounting frame 6 to move. The horn-shaped guide tube mounting frame 6 is sleeved on the yarn suction pipe 9 at one end through a mounting sleeve 10, and is movably connected to the mounting sleeve 10. The horn-shaped guide tube 8 is arranged at the other end of the horn-shaped guide tube mounting frame 6. The cylinder 5 is movably connected to the horn-shaped guide tube mounting frame 6. As shown in Figure 4-6 , a slot 13 for yarn exit is formed in the side of the horn-shaped guide tube 8, and the slot 13 is located on the side of the horn-shaped guide tube 8 away from the horn-shaped guide tube mounting frame 6. In addition, the large mouth end 14 of the horn-shaped guide tube 8 is close to the outlet of the spinning box 1, and the small mouth end 15 of the horn-shaped guide tube 8 is close to the inlet of the yarn suction pipe 9.

[0036] Through the extension and retraction of the cylinder 5, the movement of the horn-shaped guide tube mounting frame 6 is driven, and then the horn-shaped guide tube 8 is driven to approach or move away from the outlet of the spinning box 1. Then the yarn ejected from the outlet of the spinning box 1 is orderly, stably and controllably guided into the yarn suction pipe 9 through the horn-shaped guide tube 8, so as to ensure the high yarn searching accuracy in the yarn joint process.

[0037] Embodiment 2

[0038] On the basis of embodiment 1, in order to ensure the stability and controllability of the horn-shaped guide tube 8 during displacement, the moving assembly is further limited in this embodiment, so as to further illustrate the technical solution.

[0039] The moving assembly also includes a cylinder mounting frame 4, one end of the cylinder 5 is movably connected to the trumpet-shaped yarn guide tube mounting frame 6, and the other end of the cylinder 5 is movably connected to the cylinder mounting frame 4; a spring 11 is also provided between the trumpet-shaped yarn guide tube mounting frame 6 and the cylinder mounting frame 4 for restoring the position of the trumpet-shaped yarn guide tube 8.

[0040] Example 3

[0041] Based on Examples 1-2, this embodiment further defines the following in order to realize the automation of the yarn splicing process:

[0042] A distance sensor 2 is mounted on the cylinder mounting frame 4 to detect the position of the trumpet-shaped yarn guide tube 8. Electrical signals are connected between the distance sensor 2, the motor of the spinning box 1, and the cylinder 5. Preferably, the distance sensor 2 is located at the end of the cylinder mounting frame 4 near the trumpet-shaped yarn guide tube 8. A limiter 3 is located behind the distance sensor 2 to limit the distance between the trumpet-shaped yarn guide tube mounting frame 6 and the cylinder mounting frame 4. This prevents excessive contraction of the cylinder 5, which could damage the corresponding mounting frame and wear the distance sensor 2.

[0043] Among them, such as Figure 1-3 As shown, the work processes involved include:

[0044] 1. When piecing is required, the piecing robot in the vortex spinning production line moves to the spinning box 1 to be pieced with the yarn suction tube 9 and the yarn finding device;

[0045] 2. The vortex spinning control system controls the motor of the spinning box 1 to lift the spinning box 1 upward, so that the spinning box 1 is away from the yarn suction tube 9;

[0046] 3. At the same time, the vortex spinning control system controls the cylinder 5 to extend, so that the trumpet-shaped yarn guide tube mounting frame 6 moves to the position just below the outlet of the spinning box 1, until the large end 14 of the trumpet-shaped yarn guide tube 8 on the trumpet-shaped yarn guide tube mounting frame 6 is aligned with the outlet of the spinning box 1, and the small end 15 of the trumpet-shaped yarn guide tube 8 is aligned with the inlet of the yarn suction tube 9;

[0047] 4. The distance sensor 2 detects that the trumpet-shaped yarn guide tube 8 moves away and that the large end 14 of the trumpet-shaped yarn guide tube 8 is aligned with the outlet of the spinning box 1 (wherein the reference value of the displacement distance of the trumpet-shaped yarn guide tube 8 can be set according to the vortex spinning control system), and feeds back the detection signal to the vortex spinning control system;

[0048] 5. The vortex spinning control system controls the motor of the spinning box 1 to move the spinning box 1 downward, so that the spinning box 1 is close to the yarn suction tube 9. At this time, the yarn ejected from the outlet of the spinning box 1 passes through the large end 14 of the trumpet-shaped yarn guide tube 8, the trumpet-shaped yarn guide tube 8, the small end 15 of the trumpet-shaped yarn guide tube 8, the inlet of the yarn suction tube 9 and the yarn suction tube 9 in sequence, and finally enters the joint device on the joint robot;

[0049] 6. After the piecing is completed, the vortex spinning control system controls the motor of the spinning box 1 to lift the spinning box 1 upward, so that the spinning box 1 is away from the yarn suction tube 9; then, the vortex spinning control system controls the cylinder 5 to contract, so that the trumpet-shaped yarn guide tube mounting frame 6 moves away from the outlet of the spinning box 1, the yarn exits through the notch 13, and the trumpet-shaped yarn guide tube mounting frame 6 returns to its original position, completing the yarn search work;

[0050] 7. In addition, the distance sensor 2 detects that the trumpet-shaped yarn guide tube 8 moves back (that is, the distance between the distance sensor 2 and the trumpet-shaped yarn guide tube 8 becomes smaller), and feeds back the detection signal to the vortex spinning control system; and when the distance between the distance sensor 2 and the trumpet-shaped yarn guide tube 8 is a certain value (the distance reference value involved is set according to the actual situation on site), the vortex spinning control system controls the motor of the spinning box 1 to realize the downward movement of the spinning box 1 and return it to its original position.

[0051] Example 4

[0052] On the basis of Examples 1-3, this example further defines the trumpet-shaped yarn guide tube mounting bracket 6 and the mounting sleeve 10 to further illustrate this technical solution.

[0053] A connecting seat is provided between the trumpet-shaped yarn guide tube mounting frame 6 and the mounting sleeve 10, and the trumpet-shaped yarn guide tube mounting frame 6 is connected with the connecting seat by a rotating shaft. The connecting seat is provided with a limit adjustment bolt 12 for limiting the trumpet-shaped yarn guide tube mounting frame 6, and the limit adjustment bolt 12 is positioned at the inboard of the rotating shaft.

[0054] The mounting sleeve 10 is movably connected to the yarn suction tube 9. According to actual needs, the position of the mounting sleeve 10 is adjusted, and then the position of the movable assembly is adjusted, and then the position of the trumpet-shaped yarn guide tube 8 is adjusted to adapt to different spinning boxes 1.

[0055] Example 5

[0056] On the basis of Examples 1-4, this example further defines the notch 13 on the trumpet-shaped yarn guide tube 8 to further illustrate this technical solution.

[0057] The width of the slot 13 is 1.5-2.5 mm, which is suitable for the thickness of general yarns, ensuring that the yarn can smoothly exit from the trumpet-shaped yarn guide tube 8 and reducing damage to the slot 13 and the yarn. Preferably, the edge of the slot 13 is provided with an arc piece for guiding the yarn in the trumpet-shaped yarn guide tube 8 to the outside of the trumpet-shaped yarn guide tube 8, and the arc piece extends to the outside of the trumpet-shaped yarn guide tube 8.
