Description

Technical Field

[0001] The invention relates to the technical field of steel cord production, in particular to a double-mounting seat type wire wheel angle adjustment device for a steel cord stranding machine. Background Art

[0002] Cord stranding equipment is a specialized piece of industrial equipment used to combine multiple strands of wire into a single, high-strength composite wire through twisting, braiding, or winding. This process is particularly effective in tire ply production, where the stranded cord significantly enhances the tire's load-bearing capacity, impact resistance, and durability. In the steel cord stranding process, the wire pulley is a critical component for ensuring precise alignment of the multiple strands. Traditional wire pulleys typically utilize a fixed mounting structure, with an inability to adjust their steering angle, leading to the following issues:

[0003] Poor adaptability: In areas with limited space, such as the cradle spindle of the stranding machine, the fixed-angle wire wheel is difficult to adapt to the complex wire path, which can easily cause wire crossing or uneven tension;

[0004] Low adjustment efficiency: It is necessary to replace the wire wheel of different models or adjust the equipment layout, which increases downtime and production costs;

[0005] Insufficient precision: Deviation in the wire turning angle can easily lead to shift in the stranding point, affecting the mechanical properties of the composite wire.

[0006] Although attempts have been made in the prior art to achieve angle adjustment through hinge or slider structures, these solutions are often complex in structure, occupy a large space, and lack a stable positioning mechanism, making it difficult to meet the requirements of high-precision plying.

[0034] In order to better understand the technical content of the present invention, specific embodiments are given and described below with reference to the accompanying drawings.

[0035] Combine Figure 1 As shown, the present invention proposes a double-mounting seat type wire roller angle adjustment device for a steel cord stranding machine, including a mounting seat, a bearing 30, a wire roller 40 and a threaded connector 50. The mounting seat is used to connect the support plate 10 and the bearing 30, and provide a support shaft for the bearing 30 for it to rotate around a predetermined axis.

[0036] Specifically, the mounting seat includes a first mounting seat 21 and a second mounting seat 22 . A first side of the first mounting seat 21 is used to be connected to the support plate 10 , and the second mounting seat 22 is assembled to a second side of the first mounting seat 21 .

[0037] The bearing 30 is connected between the first mounting seat 21 and the second mounting seat 22 .

[0038] In this way, the bearing 30 is clamped between the first mounting seat 21 and the second mounting seat 22 , so that the bearing 30 has a stable position and a rotating shaft is provided for the bearing 30 to support the rotation of the bearing 30 .

[0039] Further, the wire wheel 40 is connected to the outer wall of the bearing 30. Like this, the wire wheel 40 can be fixed relative to the outer ring of the bearing 30, and when the steel wire passes around the surface of the wire wheel 40, the wire wheel 40 is easy to rotate.

[0040] Preferably, the outer surface of the wire wheel 40 is provided with an arc-shaped concave surface 42. Like this, the concave surface 42 can limit and guide the steel wire.

[0041] Furthermore, the threaded connector 50 passes through the second mounting seat 22 and the first mounting seat 21 in sequence, so that the second mounting seat 22, the first mounting seat 21 and the support plate 10 are fixed to each other.

[0042] In this way, the second mounting seat 22 and the first mounting seat 21 can be pressed and fixed to one side of the support plate 10 using the threaded connector 50, so that the second mounting seat 22 and the first mounting seat 21 remain relatively fixed. At this time, the wire wheel 40 has a relatively stable rotation axis.

[0043] Furthermore, the first mounting seat 21 and the second mounting seat 22 are configured to rotate around the axis of the threaded connector 50, and the wire wheel 40 is configured to rotate around the axis of the bearing 30; the axis of the threaded connector 50 is the first axis, and the axis of the bearing 30 is the second axis, and the first axis and the second axis form a predetermined angle.

[0044] In an optional embodiment, in combination with Figure 1 As shown, the first side of the first mounting seat 21 is provided with a first supporting surface 211 connected to the supporting plate 10, and the second side is provided with a second supporting surface 212. The first supporting surface 211 is perpendicular to the first axis, and the second supporting surface 212 is parallel to the second axis.

[0045] Furthermore, a third supporting surface 221 is provided on the first side of the second mounting seat 22, and a fourth supporting surface 222 is provided on the second side. The third supporting surface 221 is perpendicular to the first axis, and the fourth supporting surface 222 is parallel to the second axis. The fourth supporting surface 222 is in contact with the threaded connector 50.

[0046] The second support surface 212 is a stepped surface, and the stepped surface fits the inner ring of the bearing 30. The third support surface 221 is a stepped surface, and the stepped surface fits the inner ring of the bearing 30.

[0047] In this way, when the support surface 211 on the first side of the first mounting seat 21 is fitted with the support plate 10, the inner ring of the bearing 30 can be placed on the second support surface 212, and then the third support surface 221 of the second mounting seat 22 is placed on the inner ring of the bearing 30, and then the threaded connection 50 is sequentially passed through the inner holes of the second mounting seat 22 and the first mounting seat 21 from the fourth support surface 222, and then threadedly connected to the screw hole of the support plate 10, so that the second mounting seat 22 and the first mounting seat 21 are pressed against each other, and the bearing 30 is fixed to a suitable position and angle.

[0048] Specifically, the first supporting surface 211 and the third supporting surface 221 are configured to have circular outlines and are provided with through holes for the threaded connector 50 to pass through, and the through holes are eccentrically arranged on the first supporting surface 211 and the third supporting surface 221 .

[0049] Furthermore, when it is necessary to fine-tune the angle of the wire passing wheel 40, the threaded connector 50 can be loosened, and the first mounting seat 21 and the second mounting seat 22 can be rotated to make the first mounting seat 21 and the second mounting seat 22 rotate around the axis of the threaded connector 50. At this time, the angle of the wire passing wheel 40 is as follows: Figures 2 to 4 As shown, it can be moved between the right limit position and the left limit position to adjust the outlet angle.

[0050] In an optional embodiment, the angle A between the first axis and the second axis is 45-80°.

[0051] Combine Figure 1 As shown, the right limit position of the wire wheel 40 is deflected to the right by an angle A1, wherein A1 = 1 / 2A.

[0052] In the above embodiment, the bearing 30 includes a pair of roller bearings, a washer 31 is provided between the pair of roller bearings to form a gap, and a retaining spring 41 is provided on the inner wall of the line wheel 40, and the retaining spring 41 is arranged in the gap.

[0053] In this way, a pair of roller bearings can maintain a certain distance between them, thereby providing support for the outer line-passing wheel 40 .

[0054] In a preferred embodiment, circularly distributed scale marks are provided on the side of the first mounting seat 21 and the second mounting seat 22 facing the threaded connector 50 .

[0055] In this way, when the angle of the spool 40 needs to be adjusted, the line outlet angle of the spool 40 can be precisely controlled by controlling the change in the scale of the first mounting seat 21 and the second mounting seat 22 when they are rotated.

[0056] In combination with the above embodiments, the present invention proposes a pair of mounting seats provided on the inner side of the wire passing wheel, wherein the mounting seats and the axis of the wire passing wheel have an included angle, and the wire passing wheel can rotate freely with the mounting seats. The mounting seats are located on the inner side of the wire passing wheel. Whenever the angle of the wire passing wheel needs to be adjusted, it can be achieved by rotating the mounting seats. This structural design is relatively compact and is particularly suitable for installation in a narrow space such as the main shaft of the cradle of the cord stranding machine, and meets the demand for adjusting the steering angle of the wire passing wheel. As mentioned above, the wire passing wheel has the following advantages:

[0057] 1. Flexible adjustment: The steering angle of the wire wheel can be adjusted steplessly by loosening or tightening the threaded connector, with an adjustment accuracy of ±1°, significantly improving the alignment consistency of the wire.

[0058] 2. Space optimization: The compact mounting base and bearing integrated design reduces the overall volume by 30% compared to traditional solutions, making it suitable for small working environments.

[0059] 3. Enhanced stability: The support surface and the step surface of the bearing are designed to fit together to ensure that the wire pulley is firmly positioned after the angle is adjusted, avoiding deviation caused by vibration.

[0060] 4. Easy to operate: The scale marks on the side of the mounting base support visual angle adjustment, reducing debugging time by more than 50%.

[0061] While the present invention has been disclosed above with reference to preferred embodiments, this is not intended to limit the present invention. Persons skilled in the art will readily appreciate that various modifications and variations can be made without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the claims.
