Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] A plurality of servo motors 4 are fixedly connected to the inner wall of the frame 1 along the length direction, and an electric control box 2 is fixedly connected to the two ends of the frame 1 respectively, and a wire drum 5 is fixedly connected to the servo motor 4. The electric control box 2 cooperates with the plurality of servo motors 4, and the wire drum 5 is provided with a plurality of groups and is respectively located on both sides of the frame 1. The wire assembly is provided with a plurality of groups and is respectively cooperated with the wire drum 5. The wire assembly is cooperated with a wire junction frame assembly, and the conductor is stored on the wire drum 5. The wire drum 5 is installed on the frame 1, and the electric control box 2 can control the operation of the servo motor 4. The servo motor 4 drives the wire drum 5 to rotate, and the conductor twisting device pulls the conductor to move, and the conductor begins to detach from the wire drum 5, and then the conductor moves along the wire assembly. Among them, the distribution mode of the wire drum 5 can ensure that the two ends of the frame 1 are balanced in force, and the use effect of the frame 1 is improved. The electric control box 2 can control the operation of a plurality of servo motors 4 in different numbers, so that the corresponding servo motor 4 can be controlled to operate according to the wire drum 5 that needs to be rotated, so as to avoid the waste of electric energy caused by the operation of all servo motors 4, thereby realizing the applicability of the centralized wire feeding device;

[0033] The regulating wheel 16 is connected with a swing rod 18, and a plurality of storage slots 17 are provided on the regulating wheel 16. The regulating wheel 16 cooperates with the conductor assembly, and the side end of the swing rod 18 is hingedly connected with the guide rod 14. When the conductor moves to the regulating wheel 16 through the conductor assembly, the conductor is surrounded by the storage slot 17 provided on the regulating wheel 16, and finally moves to the junction frame assembly through the conductor assembly for centralized wire feeding, wherein the guide rod 14 is supported by the swing rod 18 through the cylinder of the prior art. When the conductor is twisted, if the moving speed of the conductor is greater than the rotating speed of the wire drum 5, the regulating wheel 16 can be rotated upward through the swing rod 18, so as to adjust the conductor that moves too fast. The conductor is buffered to avoid excessive stretching of the conductor. The storage slot 17 can ensure that the conductor has sufficient buffer length, thereby providing time for the servo motor 4 to adjust its operation. When the speed at which the servo motor 4 drives the wire drum 5 to rotate is equal to the speed at which the twisted conductor moves, the guide rod 14 resets the adjusting wheel 16 through the rocker rod 18. When the speed at which the twisted conductor moves is less than the speed at which the wire drum 5 rotates, the transmission wheel 6 can rotate downward through the rocker rod 18, thereby buffering the conductor that moves too slowly and avoiding excessive relaxation of the conductor, thereby ensuring the accuracy of the centralized wire feeding device in feeding the conductor.

[0034] In some specific embodiments, each group of wire drums 5 is connected with two groups of wire assemblies, and a support rod 3 is provided between the conductor assembly and the frame 1, and the two ends of the support rod 3 are fixedly connected to the conductor assembly and the frame 1 respectively.

The conductor moves around the grooves on the surface of the wire wheel 9 to the adjusting wheel 16. When the conductor moves from the adjusting wheel 16 to the second wire assembly, the conductor moves along the grooves on the surface of the wire wheel 9 to the wire junction frame assembly. Since the conductor is stored in a roll on the wire reel 5, the width of the wire reel 5 is greater than the width of the wire wheel 9. When the conductor moves directly along the wire wheel 9, there is a misalignment between the conductor and the wire wheel 9. The wire limiting shaft 10 provides a limiting effect for the conductor, thereby preventing the conductor from falling off when moving along the wire wheel 9.

[0036] In some specific implementation schemes, the wire junction frame assembly includes: a wire junction frame 11, a wire junction shaft 12 and a wire junction limiting shaft 13. The wire junction frame 11 is fixedly connected to the side end of the frame 1. The wire junction shaft 12 is provided with two groups and is respectively fixedly connected to the two ends of the wire junction frame 11. The wire junction shaft 12 cooperates with the wire assembly. The wire junction shaft 12 is cooperated with the conveying assembly. The wire junction limiting shaft 13 is provided with several groups and the bottom end is rotatably connected to the wire junction shaft 12. The wire junction limiting shaft 13 cooperates with the wire assembly and the wire junction shaft 12 respectively. Multiple conductors pass through the wire junction limiting shaft 13. When the conductor moves, it drives the wire junction limiting shaft 13 to rotate. Then the conductor moves along the top of the rotating shaft on the wire junction shaft 12. The conductor drives the rotating shaft to rotate. The wire junction limiting shaft 13 can separate and aggregate multiple conductors. The rotating shaft on the wire junction shaft 12 ensures that the vertical height of the conductor remains consistent.

[0037] In some specific embodiments, the conveying assembly includes a transmission wheel 6 and a transmission frame 7, the transmission frame 7 is fixedly connected to the side end of the frame 1, the transmission wheel 6 is provided with two groups and is respectively fixedly connected to the two ends of the transmission frame 7, the transmission wheel 6 cooperates with the wire converging shaft 12, when the conductor moves from the rotating axis on the wire converging shaft 12 to the transmission wheel 6, the conductor moves along the groove on the transmission wheel 6, and the conductor drives the transmission wheel 6 to rotate, the transmission wheel 6 and the rotating axis on the wire converging shaft 12 cooperate to ensure that the vertical heights of multiple conductors are consistent through the principle of two points and one line, the groove opened on the transmission wheel 6 cooperates with the wire converging limit axis 13, so as to ensure that the intervals between multiple conductors are consistent, thereby realizing the accuracy of wire feeding of the centralized wire feeding device.

[0038] In some specific embodiments, a connecting rod 21 is provided between the adjusting wheel 16 and the rocker arm 18, one end of the connecting rod 21 is fixedly connected to the rocker arm 18, and the other end of the connecting rod 21 is rotatably connected to the adjusting wheel 16. The bottom end of the guide rod 14 is hingedly connected to a fixing seat 15, and the bottom end of the fixing seat 15 is fixedly connected to the frame 1. When the adjusting wheel 16 rotates, the rocker arm 18 rotates on the frame 1, and the rocker arm 18 transmits the rotation effect to the adjusting wheel 16 through the connecting rod 21. When the rocker arm 18 rotates, the guide rod 14 moves with the rocker arm 18, and the upper and lower ends of the guide rod 14 are respectively connected to the rocker arm 18 and the fixing seat 15 by a hinged manner, thereby ensuring that the guide rod 14 always supports the rocker arm 18.

[0039] In some specific embodiments, the rocker arm 18 is rotatably connected to the frame 1 at the end away from the connecting rod 21, and a rocker slot 19 is provided at the side end of the rocker arm 18, and the rocker slot 19 is cooperated with a protection component. When the rocker arm 18 rotates, the rocker slot 19 provided in the rocker arm 18 cooperates with the protection component. When the rotation angle of the rocker arm 18 exceeds a set value, the rocker arm 18 triggers the protection component to operate, and the protection component promptly closes the centralized wire feeding device.

[0040] In some specific embodiments, the protection assembly includes: a protection rod 20 and a protector 22, the side end of the protection rod 20 cooperates with the swing groove 19, the protection rod 20 is rotatably connected to the inner wall of the protector 22, and the protector 22 is fixedly connected to the frame 1.

When the protection rod 20 is detached from the surface of the swing groove 19, the protection rod 20 triggers the protector 22 to operate the protection mechanism to close the centralized wire feeding device. When the adjusting wheel 16 rotates upward, the swing rod 18 drives the end of the protective rod 20 with the roller to move downward. At this time, the protective rod 20 triggers the protector 22 to give a positive current signal to the servo motor 4, driving the servo motor 4 to speed up the rotation speed of the wire drum 5. When the adjusting wheel 16 rotates downward, the rocker arm 18 drives the end of the protective rod 20 with the roller to move upward.
