AI Technical Summary
In existing cable delivery systems, the angle between the cable pulling section and the straightening section changes in real time, which makes the cable prone to torsional deformation around its own axis and requires a large pulling force, affecting the weather resistance of the cable insulation.
An automatic wire feeding system for cable processing was designed, including a wire feeding roller group, a wire feeding direction monitoring device, and a first support frame. The wire feeding direction monitoring device monitors the tilt direction of the cable, and the control system controls the first drive mechanism to drive the first support frame to move, so that the correction section moves in the opposite direction of the tilt direction, avoiding torsional deformation and excessive wire pulling force caused by the change of the included angle.
This effectively avoids problems such as cable torsion and excessive tension, improves the weather resistance of the cable insulation, and ensures stable operation of the cable in the outdoor environment of the substation.

Abstract
Description
Technical Field
[0001] This invention relates to the field of cable processing technology, and in particular to an automatic wire feeding system for cable processing. Background Technology
[0002] Substation construction requires a large number of fuses. A fuse is an electrical device that breaks the circuit by melting its fusible element when the current exceeds a specified value, due to the heat it generates. Fuses need to be connected to other substation equipment via cables. Since fuses operate in outdoor environments for extended periods, the insulation of the cables must have high requirements for heat resistance, corrosion resistance, and weather resistance.
[0003] Cable processing requires a wire feeding system. Existing automatic wire feeding systems typically include a spool with the cable wound on it and a set of wire feeding rollers. The spool is rotatably connected to a fixed frame, and the wire feeding rollers pull the cable through them to achieve straightness correction and automatic feeding. During the rotation of the wire feeding rollers, the cable can be divided into three parts: the first part is the correction section located within the wire feeding rollers; the second part is the pulling section located between the wire inlet of the wire feeding rollers and the spool; and the third part is the winding section still wound on the spool.
[0004] Substation cables are relatively thick. To wind cables of sufficient length, the diameter of the reel is large and the axial length of the reel is long. The cable on the reel is wound in multiple layers along the radial direction of the reel, and multiple turns are made along the axial direction of the reel in the same layer. During the process of the drive roller pulling the cable, since the fixed frame is stationary, the angle between the cable pulling section and the correction section is constantly changing in the horizontal and vertical directions. During the process of the cable feeding roller group pulling the cable, the cable is prone to torsional deformation around its own axis, and the pulling force of the cable feeding roller group needs to be set to be large. The increase in pulling force and the torsion of the cable itself will have an adverse effect on the weather resistance of the cable insulation. Summary of the Invention

Detailed Implementation
[0036] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.
[0037] In the description of this invention, it should be understood that the terms "upper," "lower," "left," "right," "top," and "bottom," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. It should be understood that the terms "first," "second," etc., are used in this invention to describe various information, but this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this invention, "first" information can also be referred to as "second" information, and similarly, "second" information can also be referred to as "first" information.
[0038] like Figures 1 to 7As shown, a preferred embodiment of the automatic wire feeding system for cable processing of the present invention includes a wire feeding roller group 1, a wire infeed direction monitoring device 2, and a first support frame 4 for mounting a wire reel 3, arranged sequentially from left to right. The lower end of the first support frame 4 is connected to a first drive mechanism 5 for driving the first support frame 4 to move. The wire infeed direction monitoring device 2 is disposed at the wire inlet of the wire feeding roller group 1 and is used to monitor the tilt direction of the correction section of the cable drawn from the wire reel 3 relative to the pulling section. The automatic wire feeding system for cable processing also includes a control system, and the wire infeed direction monitoring device 2 and the first drive mechanism 5 are both electrically connected to the control system. The control system is used to receive the tilt direction signal monitored by the wire infeed direction monitoring device 2 and control the first drive mechanism to drive the first support frame to move, so that the correction section moves in the opposite direction of the tilt direction. Therefore, the automatic wire feeding system for cable processing of the present invention can avoid cable torsional deformation and large pulling force caused by the change in the angle between the pulling section and the correction section of the cable. Specifically, the wire feeding roller group 1, the wire inlet direction monitoring device and the first support frame 4 are arranged sequentially from left to right at intervals. The first drive mechanism 5 can drive the first support frame 4 to move back and forth or up and down. When the correction section is tilted downward relative to the pulling section, the control system controls the first drive mechanism to drive the first support frame to move upward. When the correction section is tilted to the left relative to the pulling section, the control system controls the first drive mechanism to drive the first support frame to move to the right, thereby avoiding the tilt of the correction section relative to the pulling section.
[0039] The cable inlet direction monitoring device 2 includes a second support frame 21 and an annular frame 22 fixed on the second support frame 21. Multiple support rods 23 extending towards the center of the annular frame 22 are evenly spaced along the inner side of the annular frame 22. An elastic rope 24 is connected to the end of each adjacent support rod 23 near the center of the annular frame 22. Each elastic rope 24 forms a loop for threading the cable. The loop is coaxially arranged with the inlet of the cable feed roller group 1. Each elastic rope 24 is connected to a tension sensor for testing its own tension. Each tension sensor is electrically connected to the control system. The direction of the tension sensor with the larger test value is the tilt direction. In this embodiment, the loop formed by the elastic ropes 24 is a regular polygonal loop, coaxially arranged with the inlet of the cable feed roller group 1. The diameter of the inscribed circle of the regular polygonal loop matches the diameter of the cable. Furthermore, each elastic rope 24 forms a square loop. The tilt direction and degree between the tension section and the correction section of the cable can be detected in real time through the measurement values of each tension sensor. In other embodiments of the present invention, the elastic ropes 24 can be arranged into rings such as equilateral triangles, regular pentagons, and regular hexagons. In other embodiments of the present invention, the cable inlet direction monitoring device 2 can be implemented using a camera system. Specifically, a first camera can be set up to capture the angle between the cable's pulling section and the correction section in the forward-backward direction, and a second camera can be set up to capture the angle between the cable's pulling section and the correction section vertically downward. The first and second cameras can determine the tilt direction between the cable's pulling section and the correction section. In this embodiment, by setting multiple elastic ropes and using the elasticity of the elastic ropes to determine the tilt direction between the cable's pulling section and the correction section, the structure is simple and the cost is lower.
[0040] In this embodiment, the first end of each support rod 23 is movably inserted into the annular frame 22, and the second end of each support rod 23 is inclined to the right and toward the center of the annular frame 22. Each elastic rope 24 is connected to the second end of the corresponding support rod 23. Moving each support rod 23 can adjust the size of the ring. By adjusting the position of each support rod 23 on the annular frame 22, the side length of the polygon formed by the elastic ropes can be adjusted, thereby making the incoming line direction monitoring device 2 of this embodiment more adaptable.
[0041] Furthermore, the second support frame 21 is connected to a guide rail 25 arranged in a left-right direction on its left or right side. The guide rail 25 is slidably connected to baffles 26 arranged parallel to and spaced apart from the annular frame 22. The baffles 26 are detachably connected to the guide rail 25. The annular frame 22 is provided with multiple locking mechanisms. When each locking mechanism fixes each support rod 23, the first end or the second end of each support rod 23 abuts against the baffle 26. Specifically, the first locking mechanism is a locking screw 27 passing through the annular frame 22, which needs to be cut... When changing the specifications of the processed cable, connect the baffle 26 to the guide rail 25, move the baffle 26 left and right to the appropriate position, then loosen each locking screw 27, and adjust each support rod 23 one by one so that the first end or the second end of each support rod 23 abuts against the baffle 26. This ensures that each elastic rope 24 can form a regular polygon, and the axis of the regular polygon formed by each elastic rope 24 is coaxial with the axis of the wire inlet of the wire feeding roller group 1. Then tighten each locking screw 27. The baffle 26 further facilitates the adjustment of the wire feeding direction monitoring device 2.
[0042] In this embodiment, to ensure the motion accuracy of the first driving mechanism 5, the first driving mechanism 5 includes a first lead screw and slider driving mechanism 51 arranged in the vertical direction and a second lead screw and slider driving mechanism 52 arranged in the front-back direction on the slider of the first lead screw and slider driving mechanism 51. The first support frame 4 is fixed on the slider of the second lead screw and slider driving mechanism 52.
[0043] In this embodiment, to avoid the large tension on the cable caused by setting only one drive roller downstream of the wire feeding roller group, the wire feeding roller group 1 includes a support platform 11. The support platform 11 is arranged from left to right with a first drive roller 12, a straightness correction roller group 13 and a second drive roller 14. The wire feeding direction monitoring device 2 is arranged to the right of the second drive roller 14.
[0044] Specifically, the second drive roller 14 includes a first fixed plate 141 vertically fixed on the support platform 11. A first rotating shaft 142 and a second rotating shaft 143, arranged vertically and alternately, are horizontally threaded through one side of the first fixed plate 141. One end of the first rotating shaft 142 is connected to a first drive wheel 144, and one end of the second rotating shaft 143 is connected to a second drive wheel 145. The gap between the first drive wheel 144 and the second drive wheel 145 forms a clamping space for clamping cables. The gap between the first drive wheel 144 and the second drive wheel 145 is adjustable. The other end of the first drive wheel 142 is connected to a first telescopic cross-shaft coupling 146, and the other end of the first telescopic cross-shaft coupling 146 is connected to a first gear 147. The other end of the second drive wheel 143 is connected to a second telescopic cross-shaft coupling 148, and the other end of the second telescopic cross-shaft coupling 148 is connected to a second gear 149 that meshes with the first gear 147. A first motor 1415 for driving the first gear 147 or the second gear 149 is fixed on the first fixed plate 141. The arrangement of the first telescopic cross-shaft coupling 146 and the second telescopic cross-shaft coupling 148 makes the gap between the first drive wheel 144 and the second drive wheel 145 adjustable, thereby improving the adaptability of the automatic wire feeding system for cable processing of the present invention.
[0045] The second drive roller 14 includes a vertically arranged first screw 1411, a first slider 1412 and a second slider 1413 that are slidably connected to one side of the first fixed plate 141. The first slider 1412 and the second slider 1413 are arranged vertically and alternately. A first rotating shaft 142 is rotatably connected to the first slider 1412, and a second rotating shaft 143 is rotatably connected to the second slider 1413. The first fixed plate 141 is provided with a vertically arranged strip groove through which the first rotating shaft 142 and the second rotating shaft 143 pass. The first slider 1412 and the second slider 1413 are both screwed to the outside of the first screw 1411. The first fixed plate 141 is provided with a second motor 1414 for driving the first screw 1411 to rotate.
[0046] Specifically, the first slider 1412 is rotatably connected to a first threaded sleeve, and the first slider 1412 is provided with a second locking mechanism for fixing the first threaded sleeve; the second slider 1413 is rotatably connected to a second threaded sleeve, and the second slider 1413 is provided with a third locking mechanism for fixing the second threaded sleeve. Both the first and second threaded sleeves are screwed onto the outside of the first screw 1411. When it is necessary to adjust the gap between the first drive wheel 144 and the second drive wheel 145, the second and third locking mechanisms are unlocked, and then the first and second threaded sleeves are rotated to adjust the gap between the first drive wheel 144 and the second drive wheel 145 into place, and then the second and third locking mechanisms are locked.
[0047] In this embodiment, the straightness correction roller group 13 includes a vertical correction roller 131 and a horizontal correction roller 132 arranged at intervals on the support platform 11. The vertical correction roller 131 includes a vertical correction roller body and a second drive mechanism for driving the vertical correction roller body to move up and down. A third support frame 6 is fixed on the support platform 11 at the left side of the second fixed plate 1312. A first displacement sensor 61 and a second displacement sensor 62 arranged at intervals are connected to the third support frame 6. The test ends of the first displacement sensor 61 and the second displacement sensor 62 respectively abut against the top and bottom sides of the cable passing through the vertical correction roller body. The first displacement sensor 61, the second displacement sensor 62, and the second drive mechanism are all electrically connected to the control system. When the first displacement sensor 61 and the second displacement sensor 62 detect that the cable is deflected upward or downward, the control system controls the second drive mechanism to drive the vertical correction roller body to move downward or upward to adjust the position of the cable. The horizontal alignment roller 132 includes a horizontal alignment roller body and a third drive mechanism for driving the horizontal alignment roller body to move back and forth. A fourth support frame 7 is fixed to the left side of the horizontal alignment roller body on a support platform 11.

The third displacement sensor 71, the fourth displacement sensor 72, and the third drive mechanism are all electrically connected to the control system. When the third displacement sensor 71 and the fourth displacement sensor 72 detect that the cable is deflected forward or backward, the control system controls the third drive mechanism to drive the horizontal alignment roller body to move backward or forward to correct the cable position.
[0048] Specifically, the second drive mechanism includes a second screw 1311 and a second fixed plate 1312 vertically fixed on the support platform 11.

An encoder 94 is connected to the sixth roller 93. The encoder 94 is electrically connected to the control system. The encoder 94 can determine the feeding length of the cable according to the number of rotations of the sixth roller 93, thereby realizing the feeding of a cable of a specified length.
[0052] In summary, the automatic wire feeding system for cable processing of the present invention includes a wire feeding roller group 1, a wire infeed direction monitoring device 2, and a first support frame 4 for mounting a wire reel 3, arranged sequentially from left to right. The lower end of the first support frame 4 is connected to a first drive mechanism 5 for moving the first support frame 4. The wire infeed direction monitoring device 2 is located at the wire inlet of the wire feeding roller group 1 and is used to monitor the tilt direction of the correction section of the cable drawn from the wire reel 3 relative to the pulling section. The automatic wire feeding system for cable processing also includes a control system, and the wire infeed direction monitoring device 2 and the first drive mechanism 5 are both electrically connected to the control system. The control system receives the tilt direction signal monitored by the wire infeed direction monitoring device 2 and controls the first drive mechanism to drive the first support frame to move, so that the correction section moves in the opposite direction of the tilt direction. Therefore, the automatic wire feeding system for cable processing of the present invention can avoid cable torsional deformation and large pulling force caused by changes in the angle between the pulling section and the correction section of the cable.
