Description

Technical Field

[0001] This utility model relates to the field of spinning machine technology, and specifically to a yarn guiding device for spinning machines that facilitates tension adjustment. Background Technology

[0002] In the spinning process, a yarn guiding device is used to guide the yarn along a specific path and control its direction.

[0003] A search revealed a patent document with publication number CN220099295U that discloses a yarn guiding device for a spinning machine. This device consists of a mounting base, a sliding groove, a threaded column, a limiting block, a rotating disk, a tightening block, and a yarn guide cylinder. During use, the mounting base is connected to the mounting disk and has a sliding groove. The threaded column can slide within the sliding groove. Since the rotating disk is slidably connected to the threaded column, the movement of the threaded column can drive the rotating disk to move, and the rotating disk can also rotate on the threaded column, thereby adjusting the position of the yarn guide cylinder on the rotating disk to the desired yarn guiding position.

[0004] However, the aforementioned yarn guiding device can only transport the yarn and cannot effectively adjust the yarn tension during transport. This results in the yarn being relatively loose when it enters the spinning machine, making it difficult for the spinning machine to stably place the yarn and reducing the spinning effect. Utility Model Content

[0005] In view of the problems existing in the current yarn guiding device of spinning machine that is easy to adjust tension, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a yarn guiding device for spinning machines that facilitates tension adjustment, thereby solving the problem that the tension of the yarn cannot be effectively adjusted during the transmission process, which makes the yarn prone to loosening and reduces the spinning effect.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

An adjusting plate is fixedly installed at the front end of the rotating rod. Two symmetrically arranged sliding holes are opened inside the adjusting plate. A slider is slidably inserted through each of the two sliding holes. A connecting rod is rotatably installed on the outer wall of the slider. A yarn guiding wheel is fixedly installed at the end of the connecting rod.

[0009] The rear end of the rotating rod is provided with an external adjustment mechanism for driving the guide wheel to revolve.

[0010] An internal adjustment mechanism for driving the guide wheel to move is provided between the slider and the support base.

[0011] Preferably, the external adjustment mechanism includes a worm gear and a worm. The worm gear is fixedly sleeved with a rotating rod, and the worm is rotatably disposed at the lower end of the support base and cooperates with the worm gear. A rotating block is fixedly sleeved at the lower end of the worm.

[0012] Preferably, the internal adjustment mechanism includes an adjustment screw, which is rotatably disposed in the sliding hole and threaded inside the slider. The end of the adjustment screw passes through the adjustment plate and is fixedly provided with a bevel gear. Two symmetrically arranged support rods are fixedly provided on the outer wall of the support base, and a bevel gear ring is fixedly provided through the two support rods. The bevel gear and the bevel gear ring are configured to cooperate.

[0013] Preferably, the outer wall of the rotating block is provided with a plurality of anti-slip grooves that are evenly distributed axially.

[0014] Furthermore, the outer walls of both yarn guide wheels are provided with multiple spaced-apart annular yarn guide grooves.

[0015] Preferably, the outer wall of the slider is in contact with the inner wall of the sliding hole.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model discloses a yarn guiding device for a spinning machine that facilitates tension adjustment.

[0028] This utility model provides, for example Figure 1-4 A yarn guiding device for a spinning machine that facilitates tension adjustment is shown, comprising a support base 1, a rotating rod 2 rotatably passing through the upper end of the support base 1, an adjusting plate 3 fixedly provided at the front end of the rotating rod 2, two symmetrically arranged sliding holes 4 opened inside the adjusting plate 3, a slider 5 slidably passing through each of the two sliding holes 4, the outer wall of the slider 5 contacting and fitting with the inner wall of the sliding hole 4, a connecting rod 6 rotatably provided on the outer wall of the slider 5, a yarn guiding wheel 7 fixedly provided at the end of the connecting rod 6, and multiple spaced annular yarn guiding grooves 15 opened on the outer wall of each of the two yarn guiding wheels 7;

[0029] The rear end of the rotating rod 2 is provided with an external adjustment mechanism for driving the guide wheel 7 to revolve. The external adjustment mechanism includes a worm wheel 8 and a worm 9. The worm wheel 8 is fixedly sleeved with the rotating rod 2. The worm 9 is rotatably located at the lower end of the support base 1 and is configured to cooperate with the worm wheel 8. A rotating block 10 is fixedly sleeved at the lower end of the worm 9. The outer wall of the rotating block 10 is provided with multiple anti-slip grooves that are evenly distributed axially.

[0030] In order to adjust the spacing of the yarn guide rollers 7 after adjusting the angle between them, and further stabilize the yarn guiding tension, such as... Figure 1 and Figure 3-4 As shown, an internal adjustment mechanism for driving the guide wheel 7 to move is provided between the slider 5 and the support base 1. The internal adjustment mechanism includes an adjustment screw 11, which is rotatably disposed in the sliding hole 4 and threaded inside the slider 5. The end of the adjustment screw 11 passes through the adjustment plate 3 and is fixedly provided with a bevel gear 12. Two symmetrically arranged support rods 13 are fixedly provided on the outer wall of the support base 1, and a bevel gear ring 14 is fixedly provided through the two support rods 13. The bevel gear 12 and the bevel gear ring 14 are configured to cooperate.

[0031] Working principle: First, rotating the rotating block 10 drives the worm 9 to rotate. The worm 9 meshes with the worm wheel 8, driving the rotating rod 2 and the adjusting plate 3 to rotate around the central axis of the support base 1. When the adjusting plate 3 rotates, it drives the guide wheel 7 to rotate synchronously through the connecting rod 6, changing the angle of the guide wheel 7 relative to the yarn input direction. For example, when the guide angle increases, the wrap angle of the yarn around the guide wheel 7 increases, and the tension increases accordingly; when the angle decreases, the tension decreases. This process, through the self-locking characteristic of the worm gear (the worm lead angle is less than the friction angle between the meshing tooth surfaces), can stably maintain the adjusted guide angle.

[0032] Secondly, after the adjusting plate 3 rotates to the target angle, when the guide wheel 7 rotates with the adjusting plate 3, the bevel gear 12 meshes with the bevel gear ring 14 fixed on the support base 1, forcing the bevel gear 12 to rotate. The bevel gear 12 drives the adjusting screw 11 to rotate. Since the adjusting screw 11 is threadedly engaged with the slider 5, the slider 5 slides radially in the sliding hole 4, pushing the guide wheel 7 closer to or away from the central axis through the connecting rod 6. For example, when the distance between the two guide wheels 7 decreases, the bending degree of the yarn between the guide wheels increases, and the tension increases; when the distance increases, the tension decreases.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
