Description

Technical Field

[0001] The utility model relates to the technical field of yarn delivery, in particular to a yarn feeding wheel for a doubling machine capable of stabilizing yarns. Background Art

[0002] A yarn-joining machine combines multiple yarns into a single yarn, thereby increasing the yarn's strength and uniformity and improving its appearance and feel. It primarily includes modules such as a pay-off wheel, a feed wheel, a merging device, and a take-up wheel. The feed wheel typically consists of a driving wheel and a driven wheel. The yarn passes between the driving and driven wheels, where it is clamped and held. The yarn is fed by the friction generated between the two wheels as they rotate. However, yarn diameter errors can occur during yarn manufacturing. Existing feed wheels have difficulty adapting to variations in yarn diameter and are unable to consistently feed the yarn with a constant clamping force. When the yarn diameter is small, the clamping force between the driving and driven wheels decreases, failing to generate sufficient friction to pull the yarn, making it prone to slippage. When the yarn diameter is large, the clamping force between the driving and driven wheels increases, and the friction between them also increases, potentially damaging the yarn. Utility Model Content

[0032] The accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. In order to better illustrate this embodiment, certain components of the accompanying drawings may be omitted, enlarged, or reduced in size, and do not represent the actual size of the product.

[0033] For those skilled in the art, it is understandable that some well-known structures and their descriptions may be omitted in the drawings. The technical solution of the present utility model will be further described below in conjunction with the drawings and embodiments.

[0034] As shown in the accompanying drawings, a feeding wheel for a winding machine capable of stabilizing yarn includes a synchronously rotating active pulley 1 and a driven pulley 2. The active pulley 1 includes a driving shaft 11, and a wheel disc 12, a clamping ring 13 and an adjusting ring 14 sequentially arranged on the driving shaft 11. A wire clamping groove 3 is formed between the wheel disc 12, the clamping ring 13 and the driven pulley 2, and the wire clamping groove 3 is triangular in shape; the wheel disc 12, the clamping ring 13 and the driven pulley 2 cooperate to clamp the yarn.

[0035] The wheel 12 is integrally connected to the driving shaft 11 , the clamping ring 13 is slidingly connected to the driving shaft 11 , the adjusting ring 14 is rotationally connected to the driving shaft 11 , and a constant force spring 15 is connected between the adjusting ring 14 and the driving shaft 11 , which applies a constant torque to the adjusting ring 14 .

[0036] A sloped driven block 131 is provided at one end of the clamping ring 13 facing away from the wheel disc 12 , and an active block 141 is provided at one end of the adjusting ring 14 close to the wheel disc 12 . The active block 141 is in sliding contact with the driven block 131 .

[0037] It is understood that the constant-force spring 15 applies a constant torsional force to the adjusting ring 14. Under the interaction between the active block 141 and the driven block 131, the torsional force applied by the constant-force spring 15 to the adjusting ring 14 is converted into a thrust on the clamping ring 13, causing the clamping ring 13 to tend to approach the wheel 12, thereby achieving a constant clamping force on the yarn in the wire clamping groove 3.

[0038] Preferably, a mounting ring 16 is integrally sleeved on the driving shaft 11, and the adjusting ring 14 is rotatably sleeved on the outside of the mounting ring 16. An annular mounting groove is defined at one end of the adjusting ring 14, and a constant-force spring 15 is disposed within the mounting groove. One end of the constant-force spring 15 is engaged with the adjusting ring 14, and the other end of the constant-force spring 15 is engaged with the mounting ring 16. It will be understood that in this embodiment, the mounting ring 16 is circumferentially limited by a key pin, and axially limited by a retaining ring.

[0039] Preferably, the end of the mounting ring 16 facing away from the wheel disc 12 is adjustably connected to an extrusion cover 171. The extrusion cover 171 slidably abuts against the end of the adjustment ring 14 facing away from the wheel disc 12 via a damping pad 172. It is understood that the actual torsional force applied to the adjustment ring 14 is equal to the torsional force released by the constant-force spring 15 minus the friction between the extrusion cover 171 and the adjustment ring 14. By varying the extrusion force applied by the extrusion cover 171 to the adjustment ring 14, the friction between the extrusion cover 171 and the adjustment ring 14 can be adjusted, thereby varying the actual torsional force applied to the adjustment ring 14, and thereby varying the thrust applied to the clamping ring 13, ultimately achieving adjustment of the yarn clamping force within the wire clamping slot 3.

[0040] Preferably, in order to limit the axial displacement of the adjustment ring 14 , a limiting shoulder 161 is formed on the outer side wall of the mounting ring 16 , and a limiting edge 142 abutting against the limiting shoulder 161 is provided on the inner side wall of the adjustment ring 14 .

[0041] Preferably, a threaded hole 162 is defined on the end of the mounting ring 16 facing away from the wheel disc 12. An adjusting screw 18 is threadedly connected to the threaded hole 162. A through-hole for the adjusting screw 18 is formed through the extrusion cover 171. The head of the adjusting screw 18 abuts against the end of the extrusion cover 171 facing away from the wheel disc 12. It will be appreciated that by varying the depth to which the adjusting screw 18 is screwed into the mounting ring 16, the extrusion force exerted by the extrusion cover 171 on the adjusting ring 14 can be adjusted.

[0042] Preferably, a driving gear 19 is integrally sleeved on the driving shaft 11; the driven reel 2 includes a wheel body 21 and a driven gear 23 integrally connected to the wheel body 21 via a driven shaft 22, and the driving gear 19 meshes with the driven gear 23. In this embodiment, the driving shaft 11 can be externally connected to a motor, which drives the driving reel 1 and the driven reel 2 to rotate synchronously.

[0043] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. A person skilled in the art will be able to make other variations or modifications based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
