Description

Technical Field

[0001] This utility model relates to the field of steel cord production technology, and more specifically to a guide wheel with an adjustable steering angle. Background Technology

[0002] Cord twisting equipment is an industrial device specifically designed to combine multiple strands of wire (such as steel wire, fiber, nylon, etc.) into a single high-strength composite wire through twisting, braiding, or winding. This equipment is widely used in tire manufacturing, cable production, and industrial rope production, especially in the production of tire cord layers, where the twisted cords significantly enhance the tire's load-bearing capacity, impact resistance, and durability. The guide roller is the core guiding and tension control component of the cord twisting equipment, directly affecting the quality of the processed wire.

[0003] The guide roller guides the cord along a preset path through grooves on its surface, ensuring precise alignment of each strand and avoiding crossing or tangling. Traditional guide rollers can usually only rotate in one fixed direction, which limits their applicability in complex circuit layouts or application scenarios that require flexible adjustment of the cord's direction.

[0027] To better understand the technical content of this utility model, specific embodiments are provided below in conjunction with the accompanying drawings.

[0028] Combination Figure 1 As shown, this utility model proposes an adjustable steering angle guide wheel, including a mounting base, a bearing 30, a guide wheel 40, and a threaded connector 50. The mounting base is used to connect the support plate 10 and the bearing 30, and provides a support shaft for the bearing 30 to rotate around a predetermined axis.

[0029] Specifically, the mounting base includes a first mounting base 21 and a second mounting base 22. The first side of the first mounting base 21 is used to connect to the support plate 10, and the second mounting base 22 is assembled to the second side of the first mounting base 21.

[0030] The bearing 30 is connected between the first mounting base 21 and the second mounting base 22.

[0031] Thus, the bearing 30 is sandwiched between the first mounting base 21 and the second mounting base 22, giving the bearing 30 a stable position and providing a shaft to support the rotation of the bearing 30.

[0032] Furthermore, the guide wheel 40 is connected to the outer wall of the bearing 30. In this way, the guide wheel 40 can be fixed relative to the outer ring of the bearing 30, and the guide wheel 40 can easily rotate when the wire passes over the surface of the guide wheel 40.

[0033] Preferably, the outer surface of the wire guide 40 is provided with an arc-shaped concave surface 42. In this way, the concave surface 42 can limit and guide the steel wire.

[0034] Furthermore, the threaded connector 50 passes through the second mounting base 22 and the first mounting base 21 in sequence, so that the second mounting base 22, the first mounting base 21 and the support plate 10 are fixed to each other.

[0035] Thus, the threaded connector 50 can be used to press and fix the second mounting base 22 and the first mounting base 21 to one side of the support plate 10, so that the second mounting base 22 and the first mounting base 21 remain relatively fixed. At this time, the wire guide wheel 40 has a relatively stable axis of rotation.

[0036] Furthermore, the first mounting base 21 and the second mounting base 22 are configured to rotate about the axis of the threaded connector 50, and the thread guide 40 is configured to rotate about the axis of the bearing 30; the axis of the threaded connector 50 is the first axis, the axis of the bearing 30 is the second axis, and the first axis and the second axis form a predetermined angle.

[0037] In an optional embodiment, combined with Figure 1 As shown, the first mounting base 21 has a first support surface 211 connected to the support plate 10 on the first side and a second support surface 212 on the second side. The first support surface 211 is perpendicular to the first axis and the second support surface 212 is parallel to the second axis.

[0038] Furthermore, the second mounting base 22 has a third support surface 221 on the first side and a fourth support surface 222 on the second side. The third support surface 221 is perpendicular to the first axis, the fourth support surface 222 is parallel to the second axis, and the fourth support surface 222 is in contact with the threaded connector 50.

[0039] The second support surface 212 is a stepped surface, which is in contact with the inner ring of the bearing 30. The third support surface 221 is a stepped surface, which is in contact with the inner ring of the bearing 30.

[0040] Thus, when the support surface 211 on the first side of the first mounting base 21 is in contact with the support plate 10, the inner ring of the bearing 30 can be placed on the second support surface 212. Then, the third support surface 221 of the second mounting base 22 is placed on the inner ring of the bearing 30. Then, the threaded connector 50 passes through the inner holes of the second mounting base 22 and the first mounting base 21 sequentially from the fourth support surface 222, and is then threaded to the threaded hole of the support plate 10, so that the second mounting base 22 and the first mounting base 21 press against each other, fixing the bearing 30 to a suitable position and angle.

[0041] Furthermore, when it is necessary to fine-tune the wire exit angle of the wire guide wheel 40, the threaded connector 50 can be loosened, and the first mounting base 21 and the second mounting base 22 can be rotated to drive the first mounting base 21 and the second mounting base 22 around the axis of the threaded connector 50. At this time, the angle of the wire guide wheel 40 is as follows: Figures 2 to 4 As shown, it can be moved between the right extreme position and the left extreme position to adjust the exit angle.

[0042] In an optional embodiment, the included angle A between the first axis and the second axis is 45 to 80°.

[0043] Combination Figure 1 As shown, the right limit position of the guide wheel 40 is a deflection angle A1 to the right, where A1 = 1 / 2A.

[0044] In the above embodiment, the bearing 30 includes a pair of roller bearings, with a washer 31 forming a gap between the pair of roller bearings, and a retaining spring 41 is provided on the inner wall of the guide wheel 40, with the retaining spring 41 disposed in the gap.

[0045] In this way, a pair of roller bearings can maintain a certain distance, providing support for the outer guide wheel 40.

[0046] In a preferred embodiment, the first mounting base 21 and the second mounting base 22 are provided with circularly distributed scale marks on the side facing the threaded connector 50.

[0047] Thus, when it is necessary to adjust the angle of the guide wheel 40, the wire exit angle of the guide wheel 40 can be precisely controlled by controlling the change in the rotation of the first mounting base 21 and the second mounting base 22.

[0048] In conjunction with the above embodiments, the present invention proposes a pair of mounting seats on the inner side of the guide wheel. The axes of the mounting seats and the guide wheel are at an angle, and the guide wheel can rotate freely with the mounting seats. The mounting seats are located inside the guide wheel. Whenever it is necessary to adjust the angle of the guide wheel, it can be achieved by rotating the mounting seats. This structural design is relatively compact and is especially suitable for installation in confined spaces such as the main shaft of the cord twisting machine cradle, and meets the needs of adjusting the steering angle of the guide wheel.

[0049] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
