Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire feeding device technology, and in particular to a high wire feeding device. Background Technology
[0002] In existing factories, wire is typically wound onto reels or racks. During wire release from the rack, either high release or tray release is used. During free release from the rack, the wire is prone to tangling, knotting, and even breakage as it gradually decreases in size from large loops. When using high release, the coil opening gradually decreases from the rack to the entry point, increasing the constraint on the wire and subjecting it to greater tensile force. This can lead to wire deformation or even breakage. Furthermore, the release device lacks an automatic stop mechanism; the problem is only detected when the wire has completely broken, causing delays and wasted wire. Utility Model Content
[0003] The purpose of this invention is to provide a high-speed wire feeding device to solve the problems in the prior art. It can not only reduce the excessive tension on the wire at the wire inlet, but also automatically stop the machine when the wire becomes taut, thus preventing the wire from being completely pulled apart.
[0004] This utility model provides a high-speed wire feeding device, comprising:
[0005] A bracket, wherein a mounting bracket is provided on one side of the top of the bracket;
[0006] The first channel is located at the end of the mounting frame furthest from the bracket;
[0007] The rotating arm has a first end located at the bottom of the first channel and a second end located below the first end and on a side away from the first channel. The rotating arm can rotate around the axis of the first channel. When the driving wire passes through the second end of the rotating arm, the first end of the rotating arm, and the first channel in sequence, the rotating arm drives the wire to rotate.
[0008] In the high-speed wire feeding device described above, preferably, a plurality of first guide wheels are respectively arranged at intervals on the mounting frame and the bracket, and the position of the first guide wheel near the first channel is higher than the first channel.
[0009] In the high-speed wire feeding device described above, preferably, a bearing is provided in the first channel, a sleeve is provided in the bearing, and the first end of the rotating arm is connected to the end of the sleeve extending to the outside of the bearing.
[0010] In the high-speed wire feeding device described above, preferably, the high-speed wire feeding device further includes a mounting base, which is fixedly connected to a mounting frame, and the first channel is disposed within the mounting base.
[0011] In the high-speed wire feeding device described above, preferably, the rotating arm is arranged in an L-shape.
[0012] In the high-speed wire feeding device described above, preferably, the second end of the rotating arm is provided with a ring, and the opening of the ring is inclined toward the first channel.
[0013] In the high-speed wire feeding device described above, preferably, the high-speed wire feeding device further includes a tensioning assembly, which includes a fixed base, a second guide wheel, and a third guide wheel. The fixed base is fixed on the bracket, and a strip-shaped groove is formed on the fixed base along the vertical direction. The second guide wheel is fixed on the top of the strip-shaped groove, and the third guide wheel is movably disposed in the strip-shaped groove. The third guide wheel can move up and down in the strip-shaped groove, and the wire passes through the second guide wheel and the third guide wheel in sequence, and then extends from the outer tangent of the second guide wheel to the external equipment.
[0014] In the high-speed wire feeding device described above, preferably, the tensioning assembly further includes a trigger switch, the output terminal of which is electrically connected to the input terminal of an external device. When the third guide wheel contacts the second guide wheel, the trigger switch sends an emergency stop signal to the external device.
[0015] Compared with the prior art, the present invention allows the rotating arm to rotate around the first channel. Under the action of the upward spiral force of the wire, the rotating arm drives the wire to swing, thereby throwing off the wire that has reached the height, and avoiding the wire from getting tangled or taut due to tension.
[0016] By setting the first channel away from the support and adjusting the length of the rotating arm, the wire frame is positioned below the first channel. The wire entry point into the high-speed wire feeding device is far from the support, thus preventing the wire from colliding with the support during ejection and ascent. This avoids deviation in the wire's conveying path and thus affects the wire's conveying efficiency. Attached Figure Description

[0029] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0030] During the wire release process, wire 61 is prone to tangling and knotting. Therefore, it is necessary to use some wire release tools to release wire 61 from wire rack 60 and guide it to be transmitted along a certain path by traction equipment. In the high wire release device, a higher support 10 is used to guide wire 61 from wire rack 60 to the wire inlet at the top of support 10. Then, multiple guide wheels set on support 10 realize long-distance wire release. This method can reduce the tangling between wires 61 when wire 61 pops out from wire rack 60. However, since the loop formed when wire 61 is initially released from wire rack 60 is large, the loop becomes smaller and smaller when it reaches the wire inlet after passing the higher support 10. Therefore, wire 61 is prone to tautness and breakage under tension and stress. Moreover, the fewer wires 61 on wire rack 60, the smaller the loop of the wire pair will be.
[0031] See Figure 1 and Figure 2 As shown, this utility model provides a high-speed wire feeding device, including a bracket 10, a first channel 20, and a rotating arm 30, wherein:
[0032] A mounting bracket 11 is provided on one side of the top of the bracket 10. In this embodiment, the wire frame 60 is located below the corresponding position of the mounting bracket 11, and the mounting bracket 11 can be a square plate structure or an L-shaped square tube, etc.
[0033] The first channel 20 is located at the end of the mounting frame 11 furthest from the support 10. The first channel 20 is used for the passage of the wire 61. Since the wire frame 60 is generally a wide cylindrical structure, and the wire 61 is wound around its outer wall, the combined diameter of the wire 61 and the wire frame 60 is relatively large. Traditionally, the inlet end is located on the support 10. Under the traction of the rear-end traction device, the transmission path of the wire 61 is inclined. In this case, the tension on the wire 61 will vary at different positions. The tension on the wire 61 is greater at the upper part of the inclined section and relatively smaller at the lower part. This uneven tension can cause the wire 61 to experience inconsistent tension during transmission, and in severe cases, may lead to localized overstretching of the wire 61. Therefore, by setting the first channel 20 at the end of the mounting frame 11 furthest from the support 10, and with the axis of the first channel 20 relatively close to the axis of the wire frame 60, tension balance can be maintained, preventing lateral deviation of the wire 61 and preventing the wire 61 from colliding with the support 10 during its ascent, thus affecting the cable routing speed. In addition, the first channel 20 is preferably located at the bottom of the mounting bracket 11, so that the wire 61 can enter the first channel 20 without obstruction or blockage.
[0034] The first end of the rotating arm 30 is located at the bottom of the first channel 20, and the second end of the rotating arm 30 is lower than the first end of the rotating arm 30 and located on the side away from the first channel 20. The rotating arm 30 can rotate around the axis of the first channel 20. When the driving wire 61 passes through the second end of the rotating arm 30, the first end of the rotating arm 30 and the first channel 20 in sequence, the rotating arm 30 drives the wire 61 to rotate. Since the second end of the rotating arm 30 is a certain distance from the first end both laterally and longitudinally, the path of the wire 61 from the second end to the first end of the rotating arm 30 is an oblique line. This widens the loop of the wire near the first channel 20, preventing excessive tension. Furthermore, because the rotating arm 30 can rotate, the upward spiral force of the wire 61 under the traction of the traction device will cause the rotating arm 30 to rotate, thus throwing off the wire 61 near the first channel 20. This increases the loop of the wire 61 when it reaches a higher position, reducing the tension at the top and preventing tangling and tautness during ascent. It also effectively improves the smoothness of wire transmission. When the traction device pulls the wire 61 at different speeds, the rotating arm 30 can automatically adjust its swing amplitude according to the upward spiral force of the wire 61, dynamically adapting to different wire speeds. It should be noted that the rotating arm 30 only needs to have a certain rotation amplitude under the spiral force of the wire 61; it does not need to rotate 360 degrees.
[0035] In this embodiment, a plurality of first guide rollers 40 are respectively arranged at intervals on the mounting frame 11 and the bracket 10. The position of the first guide rollers 40 near the first channel 20 is higher than the first channel 20. After the wire 61 comes out of the first channel 20, it passes through a plurality of first guide rollers 40 in sequence. The first guide rollers 40 can provide precise guidance for the wire 61, so that it is transmitted along a predetermined path. The spacing between the plurality of first guide rollers 40 can be adjusted as needed, and they are fixed to the mounting frame 11 or the bracket 10 by means of bolts or other methods.
[0036] See Figure 3 As shown, to enable the first end of the rotating arm 30 to rotate around the axis of the first channel 20, a bearing 21 is provided inside the first channel 20, and a sleeve 22 is provided inside the bearing 21. The first end of the rotating arm 30 is connected to the end of the sleeve 22 that extends to the outside of the bearing 21. The outer ring of the bearing 21 is connected to the inner wall of the first channel 20, and the inner ring of the bearing 21 is connected to the sleeve 22. The rotation of the rotating arm 30 is achieved by the rotation of the inner ring of the bearing 21 relative to the outer ring. Preferably, a longer bearing 21 is used, which has a larger contact area with the first channel 20. Both the upper and lower ends of the sleeve 22 extend to the outside of the first channel 20. The first end of the rotating arm 30 can be directly welded to the sleeve 22 or sleeved on the outer wall of the sleeve 22 through a ring structure, which is not limited here.
[0037] In this embodiment, see Figure 3 As shown, the high-speed wire feeding device also includes a mounting base 200, which is fixedly connected to the mounting frame 11. A first channel 20 is disposed within the mounting base 200. The mounting base 200 is disposed on the surface of the mounting frame 11. The first channel 20 is opened in the vertical direction, allowing vertical conduction, and the first channel 20 is preferably cylindrical.
[0038] See Figure 1 and Figure 2 As shown, in one feasible embodiment, the rotating arm 30 is L-shaped, including a first arm 31 and a second arm 32, with the angle between the first arm 31 and the second arm 32 being 90 degrees. In this embodiment, the first arm 31 is preferably set to be parallel to the end face of the first channel 20, and the preset angle between the first arm 31 and the second arm 32 is a right angle. Of course, the first arm 31 may also have a certain angle with the end face of the first channel 20, or the angle between the first arm 31 and the second arm 32 may be greater than 90 degrees; the purpose of both is to adjust the range in which the wire 61 can be swung.
[0039] See Figures 1-2 and Figure 5As shown, the second end of the rotating arm 30 is provided with a ring 33, the opening of which is inclined towards the first channel 20. The ring 33 is used for the wire 61 to pass through. The inclined opening of the ring 33 towards the first channel 20 has a guiding function, and the inclined opening allows the wire 61 to contact the ring 33 at a smoother angle when entering the ring 33, avoiding excessive friction and collision between the wire 61 and the edge of the ring 33, thus helping to reduce wear on the surface of the wire 61. Furthermore, the ring 33 can also be provided with a beveled surface 330 inclined towards the axis, and the edge of the ring 33 can be rounded, making the wire 61 pass through the ring 33 more smoothly and reducing wear.
[0040] Although the high-speed wire-laying device reduces the risk of wire 61 tangling by adding structures such as the rotating arm 30, there is still a risk that the wire 61 may break due to tension caused by factors such as the speed of the traction equipment and the ejection of the wire 61. Therefore, see Figures 1-2 As shown, the high-speed wire feeding device also includes a tensioning component 50, which is used to automatically stop the machine when the wire 61 is taut, so as to avoid the operator only discovering the wire 61 after it has been pulled apart, thereby reducing the loss of the wire 61 and reducing manpower and material resources.
[0041] See Figures 1-2 and Figure 4 As shown, in the embodiments proposed in this application, the tensioning assembly 50 includes a fixed base 51, a second guide wheel 52, and a third guide wheel 53. The fixed base 51 is fixed on the bracket 10, and a strip groove 54 is formed on the fixed base 51 along the vertical direction. The second guide wheel 52 is fixed on the top of the strip groove 54, and the third guide wheel 53 is movably disposed in the strip groove 54. The third guide wheel 53 can move up and down along the strip groove 54. The wire 61 passes through the second guide wheel 52 and the third guide wheel 53 in sequence and then extends from the outer tangent of the second guide wheel 52 to the external device. The wire 61 connects the second guide wheel 52 and the third guide wheel 53. Therefore, during the movement of the wire 61, when the tension of the wire 61 increases, the third guide wheel 53 moves closer to the second guide wheel 52 along the strip groove 54. When the tension of the wire 61 decreases, the third guide wheel 53 moves away from the second guide wheel 52. The wire 61 passing through the tensioning component 50 has a certain floating space, thereby realizing the adjustment of the tension of the wire 61.
[0042] To better avoid the risk of wire 61 breaking, when the tensioning assembly 50 reaches its maximum adjustment limit and still cannot adjust the tension of wire 61, an emergency stop is initiated via external equipment to cancel the traction force on wire 61, allowing the operator to promptly check and adjust. Specifically, the tensioning assembly 50 also includes a trigger switch (not shown in the figure). The output of the trigger switch is electrically connected to the input of the external equipment. When the third guide wheel 53 contacts the second guide wheel 52, the trigger switch sends an emergency stop signal to the external equipment. The trigger switch can be a micro switch, limit switch, or displacement sensor, etc., and is set at a preset position on the fixed base or on the contact surface between the second guide wheel 52 and the third guide wheel 53. The external equipment can be a traction device or an electrical cabinet, etc., and is not limited here. It should be noted that the circuits and controls involved in this utility model are all existing technologies and will not be described in detail here.
[0043] In this embodiment, the traction device is located at the output end of the wire 61. Driven by the traction device, the wire 61 is ejected from the wire frame 60 and passes sequentially through the ring 33, sleeve 22, first channel 20, multiple first guide rollers 40, second guide roller 52, and third guide roller 53. It then winds around to the upper end face of the second guide roller 52 and extends from its tangent to the traction device. Due to the upward spiral force, the rotating arm 30 rotates, thereby throwing off the wire 61 that reaches the vicinity of the first channel 20, making the release of the wire 61 smoother and achieving the purpose of preventing the wires 61 from tangling. When the tension of the wire 61 changes, the third guide roller 53 moves up and down along the strip groove 54 to adjust the tension of the wire 61. When the third guide roller 53 moves to contact the second guide roller 52, the traction device can stop in an emergency to prevent the wire 61 from being pulled apart.

The above description is only a preferred embodiment of this utility model, but the scope of implementation of this utility model is not limited to what is shown in the drawings. Any changes made in accordance with the concept of this utility model, or modifications to equivalent embodiments, that do not exceed the spirit covered by the specification and drawings, shall be within the protection scope of this utility model.
