Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, specifically to a yarn guiding device for a spinning machine. Background Technology

[0002] The spinning frame is a crucial spinning machine in textile engineering. Its function is to transform semi-finished products into fine yarn bobbins through steps such as drafting, twisting, and winding, for subsequent weaving or knitting. During the spinning process, the yarn needs to pass through a guide hook, which is mounted on a guide plate. The guide plate is mounted on a long beam, and the rear end of the guide plate has louvers that are bolted to the long beam. The lower end of the louvers is pivotally connected to the main body plate. The front end of the guide hook is the yarn hanging position, and the rear end is a straight or U-shaped pressing part. The pressing part is generally locked to the main body plate by a pressure plate and bolts. Currently, when it is necessary to change the extension stroke of the guide hook, a screwdriver is required to loosen the bolts, which is inconvenient.

[0003] A Chinese utility model patent (publication number: CN220503316U) discloses a yarn guiding device for a spinning machine. When changing the extension stroke of the yarn guiding hook, the wing nut is rotated so that the pressure block leaves the slider, and the slider can be moved quickly along the T-slot, thereby changing the extension stroke of the yarn guiding hook. When fixing the position of the yarn guiding hook, it is only necessary to tighten the wing nut to press the pressure block onto the slider. Since the pressure block and the slider are matched by the meshing teeth, it is not necessary to tighten the wing nut very much.

[0004] Although it achieves the adjustment of the yarn guide hook stroke, its mechanical operation path has significant efficiency shortcomings: in actual production, the operator needs to complete four steps in sequence: loosening the positioning nut → pushing the pressure block upward → dragging the slider laterally → tightening the nut again. The operation steps are relatively cumbersome and inconvenient. Therefore, a yarn guide device for a spinning machine is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a yarn guiding device for a spinning machine to solve the problem mentioned in the background art that the mechanical operation path for adjusting the stroke of the yarn guiding hook has significant efficiency shortcomings: in actual production, the operator needs to complete four steps in sequence: loosening the positioning nut → pushing the pressure block upward → dragging the slider laterally → tightening the nut again. The operation steps are cumbersome and the convenience is poor.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a yarn guiding device for a spinning machine, comprising a main body plate, wherein an installation groove is provided inside the main body plate, and an adjustment component is provided inside the installation groove, wherein the adjustment component comprises a slider, a toothed plate, a yarn guiding hook, an adjusting rod, a limiting gear, an adjusting gear, a spring, a push ring, a limiting toothed ring, and a rotating ring;

[0012] Preferably, a rotating shaft is fixedly connected to the rear part of the upper surface of the main body plate, and louvers are rotatably connected to the outer side wall of the rotating shaft.

[0013] Preferably, a torsion spring is fitted onto the outer wall of the aforementioned rotating shaft.

[0014] Preferably, the two ends of the aforementioned torsion spring abut against the louvers and the main body plate, respectively.

[0015] Compared with the prior art, this utility model, employing the above technical solution, has the following technical advantages: By pressing the adjustment knob, the adjustment rod drives the limiting gear to disengage from the limiting gear ring. Then, rotating the adjustment knob causes the adjustment rod to rotate the adjustment gear. The adjustment gear, through its teeth, drives the toothed plate to move, which in turn drives the slider to move. The slider then drives the yarn guide hook, thereby adjusting the extension stroke of the yarn guide hook. After adjustment, under the push of the spring, the limiting gear inserts into the limiting gear ring, at which point the positions of the slider and the yarn guide hook are fixed. Compared with the prior art, this utility model allows for adjustment of the yarn guide hook's extension stroke simply by pressing and rotating the adjustment knob, resulting in a simple and highly convenient operation.

[0025] Example

[0026] In the existing technology, the mechanical operation path for adjusting the stroke of the yarn guide hook has significant efficiency shortcomings: in actual production, the operator needs to complete four steps in sequence: loosening the positioning nut → pushing the pressure block upward → dragging the slider laterally → tightening the nut again. The operation steps are cumbersome and inconvenient.

[0027] Please see Figures 1-5 This utility model provides a technical solution: a yarn guiding device for a spinning machine, including a main plate 11, an installation groove 12 is provided inside the main plate 11, and an adjustment component 101 is provided inside the installation groove 12. The adjustment component 101 includes a slider 13, a toothed plate 14, a yarn guiding hook 15, an adjustment rod 17, a limiting gear 18, an adjusting gear 19, a spring 20, a push ring 21, a limiting toothed ring 22, and a rotating ring 23.

[0028] The yarn guide hook 15 is fixedly connected to the front surface of the slider 13, the toothed plate 14 is fixedly connected to the upper surface of the slider 13, the limiting gear 18, the adjusting gear 19 and the push ring 21 are all fixedly connected to the outer side wall of the adjusting rod 17, and the outer side wall of the adjusting gear 19 is meshed with the upper surface of the toothed plate 14. Since the adjusting gear 19 is meshed with the toothed plate 14, when the adjusting rod 17 rotates, the adjusting gear 19 can drive the toothed plate 14 to move through the teeth, the toothed plate 14 can drive the slider 13 to move, and the slider 13 can drive the yarn guide hook 15, thereby adjusting the extension stroke of the yarn guide hook 15.

[0029] Spring 20, push ring 21, limiting gear ring 22 and rotating ring 23 are all sleeved on the outside of adjusting rod 17. The outer side wall of limiting gear 18 is meshed with the inner side wall of limiting gear ring 22. Rotating ring 23 is rotatably connected to one side of the inner side wall of mounting groove 12. Limiting gear ring 22 is embedded in the inside of main body plate 11. The position of limiting gear 18 can be limited by limiting gear ring 22, thereby fixing the position of adjusting rod 17 and adjusting gear 19. When the position of adjusting gear 19 is fixed, the position of toothed plate 14 is limited, thereby fixing the position of slider 13 and yarn guide hook 15.

[0030] In this embodiment, specifically: one end of the spring 20 abuts against one side of the push ring 21, and the other end of the spring 20 abuts against one side of the rotating ring 23. Under the push of the spring 20, the limiting gear 18 can always be located inside the limiting gear ring 22, thereby limiting the position of the slider 13 and the yarn guide hook 15.

[0031] In this embodiment, specifically: the adjusting rod 17 is located inside the main body plate 11, and the adjusting rod 17 is rotatably and slidably connected to the main body plate 11. When the adjusting rod 17 is pressed, the spring 20 is compressed, and the limiting gear 18 moves out of the limiting gear ring 22. When the adjusting rod 17 is rotated, the slider 13 is driven.

[0032] In this embodiment, specifically: the slider 13 is slidably connected to the inner wall of the mounting groove 12, and the adjusting gear 19 is located inside the mounting groove 12. The position of the slider 13 can be limited by the mounting groove 12.

[0033] In this embodiment, specifically: one end of the adjusting rod 17 is fixedly connected to an adjusting knob 16, which is located outside the main body plate 11. The adjusting knob 16 can be used to push or rotate the adjusting rod 17.

[0034] In this embodiment, specifically: a rotating shaft 32 is fixedly connected to the rear part of the upper surface of the main body plate 11, a louver 31 is rotatably connected to the outer side wall of the rotating shaft 32, a torsion spring 33 is sleeved on the outer side wall of the rotating shaft 32, and the two ends of the torsion spring 33 abut against the louver 31 and the main body plate 11 respectively. The louver 31 is fixed to the long beam of the spinning machine (not shown in the figure), and the torsion spring 33 can keep the louver 31 and the main body plate 11 clamped together.

[0035] The working principle or structural principle is as follows: When adjusting the extension stroke of the yarn guide hook 15, press the adjustment knob 16. The adjustment knob 16 pushes the adjustment rod 17, which drives the limiting gear 18 to disengage from the limiting gear ring 22. At the same time, the spring 20 is compressed. Then, rotate the adjustment knob 16, which drives the adjustment rod 17 to rotate. The adjustment rod 17 drives the adjustment gear 19 to rotate. Since the adjustment gear 19 is meshed with the toothed plate 14, when the adjustment rod 17 rotates, the adjustment gear 19 can drive the toothed plate 14 to move through the teeth. The toothed plate 14 drives the slider 13 to move, and the slider 13 drives the yarn guide hook 15. Thus, the extension stroke of the yarn guide hook 15 can be adjusted. After the adjustment is completed, release and slightly adjust the position of the adjustment knob 16 to align the limiting gear 18 with the limiting gear ring 22. Under the push of the spring 20, the limiting gear 18 is inserted into the inside of the limiting gear ring 22. At this time, the positions of the slider 13 and the yarn guide hook 15 are fixed.

[0036] In summary, this utility model allows for adjustment of the extension stroke of the yarn guide hook 15 by pressing and rotating the adjustment knob 16. The operation is simple and highly convenient.
