Description

Technical Field

[0001] This utility model relates to the field of cable guide wheel technology, specifically to a width-adjustable cable guide wheel. Background Technology

[0002] During the winding process of finished enameled wire, the winding guide rollers in the winding machine are used to assist in winding the wire to ensure that the wire is wound neatly on the reel.

[0003] Traditional wire guide rollers have a fixed groove width. For example, patent application CN207038200U, entitled "Wire Guide Roller, Active Take-up Roller, Wire Guide Roller, and Wire Guide Roller," discloses a wire guide roller, an active take-up roller, a wire guide roller, and a wire guide roller. The roller includes a wheel body, a disc, and a through-hole at the center of the disc. The disc includes an annular wheel surface and a circular rim on the outer periphery of the wheel surface, with the wheel surface and rim integrally connected. The surface of the rim is recessed to form a V-shaped groove. This means the groove width cannot be flexibly adjusted according to the actual diameter of the enameled wire. This results in ineffective guidance and positioning of the wire when dealing with enameled wires of different diameters, potentially leading to uneven arrangement, tangling, and disordered layering during take-up, affecting take-up quality and, in severe cases, damaging the enameled wire and increasing production costs. To solve the above problems, the only solution is to replace the wire guide rollers with corresponding width specifications for the wire grooves according to the different diameters of the enameled wires. However, the replacement process is quite complicated, which is not only time-consuming and labor-intensive, but also reduces production efficiency. Utility Model Content

[0004] The purpose of this utility model is to address the above-mentioned shortcomings by providing a width-adjustable cable guide wheel with a reasonable structural design and adjustable cable groove width.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] An adjustable-width cable guide wheel includes an axle, an inner half-wheel, an outer half-wheel, an adjusting cup seat, a spring, and a pressure cap. The inner half-wheel is mounted on the axle via a first bearing, and its outer circumferential surface has a radially protruding inner end to form an inner width-limiting surface. The outer half-wheel is mounted on the adjusting cup seat via a second bearing, and the adjusting cup seat is sleeved on the axle. The outer half-wheel has a fitting portion near the inner half-wheel that can be fitted onto the outer end of the outer circumferential surface of the inner half-wheel. The end face of the fitting portion has an outer width-limiting surface, and a cable groove is formed between the inner and outer width-limiting surfaces. The pressure cap is axially movable on the axle. The spring is sleeved on the axle, with one end abutting against the pressure cap and the other end abutting against the adjusting cup seat.

[0007] As a preferred embodiment of this utility model, the inner end of the adjusting cup seat is radially narrowed to form a bearing mounting position, and the second bearing is fitted on the bearing mounting position, which is securely installed and has a good fit; the outer end of the adjusting cup seat is radially enlarged to form an operating part, and the outer end face of the operating part is provided with an operating cavity, and the spring is located in the operating cavity. The structure is reasonably designed and has a good installation effect.

[0008] In a preferred embodiment of this invention, the adjusting cup seat has an axial hole through which the axle passes. A protective sleeve is provided in the operating cavity corresponding to the edge of the hole, protecting the axle. An inner spring limiting groove is formed between the protective sleeve and the cavity wall of the operating cavity. The inner spring limiting groove limits the spring, preventing displacement or tilting during use and ensuring the spring remains in the correct position, resulting in good operational stability.

[0009] In a preferred embodiment of this invention, the outer end face of the axle is provided with an adjusting screw hole, and the center position of the pressure cap is provided with a through hole. The adjusting screw passes through the through hole and is screwed into the adjusting screw hole. The position of the pressure cap can be controlled by adjusting the screw, thereby adjusting the spring pressure and controlling the width of the groove.

[0010] In a preferred embodiment of this invention, the inner wall of the pressure cap is provided with an outer spring limiting groove. This groove, in conjunction with the inner spring limiting groove, provides a more stable limit for the spring. This ensures the spring maintains a stable position and posture during operation, preventing displacement or deformation due to vibration or impact, ensuring the spring can continuously and stably apply pressure, and guaranteeing the stability of the groove width.

[0011] In a preferred embodiment of this invention, the axle is provided with a positioning boss or positioning groove corresponding to the inner ring positions of the first and second bearings, and the positioning groove is provided with an inner retaining ring. This prevents the bearings from axially moving on the axle and ensures the fitting accuracy and stability between the inner rings of the first and second bearings and the axle.

[0012] As a preferred embodiment of this utility model, the inner half-wheel is provided with a first positioning protrusion or a first positioning groove corresponding to the outer ring of the first bearing. The first positioning groove is provided with a first retaining ring to accurately position the outer ring of the first bearing, prevent it from moving relative to the inner half-wheel, and ensure stable engagement between the inner half-wheel and the outer ring of the first bearing.

[0013] In a preferred embodiment of this invention, the outer half-wheel is provided with a second positioning protrusion or a second positioning groove corresponding to the outer ring of the second bearing, and a second retaining ring is provided on the second positioning groove. This effectively fixes the outer ring of the second bearing, preventing it from shifting on the outer half-wheel and ensuring a stable fit between the outer half-wheel and the outer ring of the second bearing.

[0014] The beneficial effects of this utility model are as follows: The design is reasonable. The spring is sleeved on the axle, with its two ends abutting against the pressure cap and the adjusting cup seat respectively. A groove is formed between the outer width-limiting surface of the adjusting cup seat and the inner width-limiting surface of the inner half-wheel. The pressure of the spring can be adjusted by axially moving the pressure cap on the axle, causing the outer width-limiting surface of the outer half-wheel to move closer to or further away from the inner width-limiting surface of the inner half-wheel. This allows for flexible adjustment of the groove width according to different diameters of enameled wire, eliminating the need to replace guide wheels, avoiding cumbersome replacement procedures, improving production efficiency, and reducing costs associated with frequent guide wheel replacements. Furthermore, the spring's elasticity allows the groove to better fit the enameled wire, providing good guidance and effectively preventing uneven wire arrangement during winding, thus improving winding quality. In addition, this utility model has a simple structure, is easy to operate, and has low cost, making it suitable for widespread application.

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0023] See Figures 1 to 7 This embodiment provides a width-adjustable cable guide wheel, which includes a wheel axle 1, an inner half wheel 2, an outer half wheel 3, an adjusting cup seat 4, a spring 5, and a pressure cap 6.

[0024] The inner half-wheel 2 is mounted on the axle 1 via a first bearing 7. The inner end of the outer circumference of the inner half-wheel 2 radially protrudes to form an inner width-limiting surface 21. The outer half-wheel 3 is mounted on the adjusting cup seat 4 via a second bearing 8. The adjusting cup seat 4 is fitted onto the axle 1. Specifically, the inner end of the adjusting cup seat 4 radially narrows to form a bearing mounting position 41, on which the second bearing 8 is fitted securely and with good fit. The outer end of the adjusting cup seat 4 radially widens to form an operating part 42. The outer end face of the operating part 42 has an operating cavity 43, and the spring 5 is located within the operating cavity 43. This design is reasonable and provides good installation. Preferably, a positioning boss 11 or a positioning groove 12 is provided on the axle 1 corresponding to the inner ring positions of the first bearing 7 and the second bearing 8. The positioning groove 12 has an inner retaining ring. This prevents axial movement of the bearings on the axle 1 and ensures the fitting accuracy and stability between the inner rings of the first bearing 7 and the second bearing 8 and the axle 1.

[0025] A first positioning protrusion 22 or a first positioning groove 23 is provided on the inner half wheel 2 corresponding to the outer ring position of the first bearing 7. A first retaining ring is provided on the first positioning groove 23 to accurately position the outer ring of the first bearing 7, prevent it from moving relative to the inner half wheel 2, and ensure that the inner half wheel 2 and the outer ring of the first bearing 7 are stably engaged.

[0026] A second positioning protrusion 31 or a second positioning groove 32 is provided on the outer half-wheel 3 corresponding to the outer ring position of the second bearing 8, and a second retaining ring is provided on the second positioning groove 32. This can effectively fix the outer ring of the second bearing 8, prevent it from shifting on the outer half-wheel 3, and ensure a stable fit between the outer half-wheel 3 and the outer ring of the second bearing 8.

[0027] The adjusting cup seat 4 has an axial hole 44 through which the axle 1 passes. The operating cavity 43 has a protective sleeve 45 corresponding to the edge of the hole 44. The protective sleeve 45 protects the axle 1. An inner spring limiting groove 46 is formed between the protective sleeve 45 and the cavity wall of the operating cavity 43. The inner spring limiting groove 46 limits the spring 5, preventing displacement or tilting during use, ensuring the spring 5 is always in the correct position and has good working stability.

[0028] The outer half-wheel 3 has a sleeve portion 33 located near the inner half-wheel 2, which can be fitted onto the outer end of the outer circumference of the inner half-wheel 2. The end face of the sleeve portion 33 has an outer width-limiting surface 331, and a groove 9 is formed between the inner width-limiting surface 21 and the outer width-limiting surface 331. Specifically, an adjusting screw hole 13 is provided on the outer end face of the axle 1, and a through hole 61 is provided at the center of the pressure cap 6. An adjusting screw 10 passes through the through hole 61 and is screwed into the adjusting screw hole 13. The position of the pressure cap 6 can be controlled by adjusting the screw 10, thereby adjusting the pressure of the spring 5 and controlling the width of the groove 9.

[0029] The pressure cap 6 is axially movable on the axle 1. The spring 5 is sleeved on the axle 1, with one end abutting against the pressure cap 6 and the other end abutting against the adjusting cup seat 4. Preferably, an outer spring limiting groove 62 is provided on the inner wall of the pressure cap 6. By cooperating with the inner spring limiting groove 46, a more stable limiting is formed for the spring 5. This ensures that the spring 5 maintains a stable position and posture during operation, preventing displacement or deformation of the spring 5 due to vibration or impact, ensuring that the spring 5 can continuously and stably apply pressure, and guaranteeing the width stability of the groove 9.

[0030] In use, the pressure of the spring 5 can be adjusted by axially moving the pressure cap 6 on the axle 1, so that the outer width limiting surface 331 of the outer half wheel 3 moves closer to or further away from the inner width limiting surface 21 of the inner half wheel 2, thereby flexibly adjusting the width of the wire groove 9. The width of the wire groove 9 can be flexibly adjusted according to the enameled wire of different diameters, without the need to replace the guide wheel, avoiding the tedious replacement process and improving work efficiency.
