The traction device is mainly composed of a traction wheel and a motor. A circular groove is provided on the traction wheel, and the conductor is wrapped around the circular groove. The motor drives the traction wheel to rotate to pull the conductor.

[0004] However, when the conductor is wrapped around the circular groove, only the bottom end of the conductor is supported by the circular groove, and the cross-section of the conductor is circular, which causes the conductor to slide in translation when the conductor is rotated by the traction wheel, thereby affecting the roundness of the conductor after passing through the traction device.

[0018] Beneficial effects of the present invention:

[0019] 1. When the conductor is twisted through the high-speed conductor twisting equipment, the motor starts, and the motor drives the driven shaft to rotate through the transmission assembly. The two sets of driven shafts respectively drive the conveying traction wheel and the discharging traction wheel to rotate. The conductor is wound around the conveying traction wheel once and then around the discharging traction wheel once, so as to pull the conductor. The rotation of the conveying traction wheel and the discharging traction wheel drives the conductor to rotate and move. When the conductor is separated from the discharging traction wheel, the wire pressing assembly limits the conductor to prevent the conductor from loosening on the discharging traction wheel. When the conductor is pulled, the conductor is held against the limiting groove, and the two ends of the conductor are respectively held against the two ends of the inner wall of the limiting groove. The shape of the limiting groove realizes the holding and limiting of the two ends of the conductor in the horizontal direction, thereby avoiding the deviation of the conductor on the limiting groove, ensuring the stability of the conductor when being pulled on the limiting groove, and thus ensuring the roundness of the conductor when being pulled.

[0020] 2. The shape of the limit groove can limit the conductors of different diameters, further improving the applicability of the limit groove. When the traction device pulls the conductor, the limit groove reduces the error when the conductor is discharged, so that the length of the conductor traction can be counted according to the number of rotations of the discharge traction wheel, ensuring the accuracy of counting the length of the pulled conductor. It should be noted that when the conductor is twisted, the speed of the high-speed conductor twisting equipment is often relatively high, and the limit groove can ensure the precision of the traction device in pulling the conductor.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0030] like Figure 1-Figure 6 As shown, a traction device of a high-speed conductor stranding device comprises: a motor 1, a discharging traction wheel 11 and a conveying traction wheel 2,

[0031] The motor 1 is connected with a transmission assembly, and the transmission assembly is connected with two sets of driven shafts 3. When the conductor is twisted by the high-speed conductor twisting device, the motor 1 runs, and the motor 1 drives the driven shaft 3 to rotate through the transmission assembly.

[0032] The discharging traction wheel 11 is fixedly connected to the driven shaft 3, and the discharging traction wheel 11 is connected with a wire pressing assembly. The discharging traction wheel 11 has a limiting groove 21 around the axis line, and the conveying traction wheel 2 is arranged at the bottom of the discharging traction wheel 11. The conveying traction wheel 2 is fixedly connected to the driven shaft 3, and the conveying traction wheel 2 has a limiting groove 21 around the axis line. The cross section of the limiting groove 21 is V-shaped. The two groups of driven shafts 3 respectively drive the conveying traction wheel 2 and the discharging traction wheel 11 to rotate. The conductor is wound around the conveying traction wheel 2 once and then around the discharging traction wheel 11 once, so as to pull the conductor. The rotation of the conveying traction wheel 2 and the discharging traction wheel 11 drives the conductor to rotate and move. When the conductor is separated from the discharging traction wheel 11, the wire pressing assembly limits the conductor to prevent the conductor from loosening on the discharging traction wheel 11. When the conductor is pulled, the conductor is held against the limiting groove On 21, the two ends of the conductor are respectively abutted against the two ends of the inner wall of the limiting groove 21. The shape of the limiting groove 21 realizes the abutment and limitation of the two ends of the conductor in the horizontal direction, thereby avoiding the deviation of the conductor on the limiting groove 21, ensuring the stability of the conductor when being pulled on the limiting groove 21, thereby ensuring the roundness of the conductor when being pulled. The shape of the limiting groove 21 can limit conductors of different diameters, further improving the applicability of the limiting groove 21. When the traction device pulls the conductor, the limiting groove 21 reduces the error when the conductor is discharged, so that the length of the conductor traction can be counted according to the number of revolutions of the discharging traction wheel 11, ensuring the accuracy of counting the length of the pulled conductor. It should be noted that when the conductor is twisted, the speed of the high-speed conductor twisting equipment is often relatively high, and the limiting groove 21 can ensure the precision of the traction device in pulling the conductor.

[0033] In some specific embodiments, the transmission assembly includes: a driven wheel 5, a driving wheel 8 and a driving shaft 10, the outer wall of the driving wheel 8 is meshingly connected with a driving belt 9, the driving wheel 8 is fixedly connected to the driving shaft 10, the driving belt 9 is meshingly connected to the motor 1, the driven wheel 5 is provided with two groups and the outer wall is meshingly connected with a driven belt 6, the driven wheel 5 is fixedly connected to the driven shaft 3, the driven belt 6 is meshingly connected to the driving shaft 10, when the motor 1 is running, the motor 1 drives the driving belt 9 to rotate, the driving belt 9 drives the driving wheel 8 to rotate, the driving wheel 8 drives the driving shaft 10 to rotate, the driving shaft 10 drives the corresponding driven wheels 5 to rotate through the two groups of driven belts 6, the driven wheel 5 drives the driven shaft 3 to rotate, so that the two groups of driven wheels 5 respectively drive the conveying traction wheel 2 and the discharging traction wheel 11 to rotate.

[0034] In some specific embodiments, the driven belt 6 is connected with a tensioner 7. When the driven belt 6 is used for a long time, it will become loose. The tensioner 7 can support the driven belt 6 to ensure that the driven belt 6 is appropriately tensioned when it is mounted on the driven wheel 5, thereby ensuring that the driven belt 6 stably drives the driven wheel 5 to rotate.

[0035] In some specific implementation schemes, the outer wall of the driven shaft 3 is sleeved with a line splitting wheel 15, the top of the line splitting wheel 15 is tilted away from the conveying traction wheel 2, a plurality of balls 17 are arranged between the line splitting wheel 15 and the driven shaft 3, the line splitting wheel 15 is matched with a limiting wheel 16, the ball 17 is rollingly connected to the inner wall of the line splitting wheel 15, the limiting wheel 16 is matched with the discharge traction wheel 11, when the conductor is twisted and discharged from the high-speed conductor twisting device, the conductor is first wound on the line splitting wheel 15, and then wound on the limiting wheel 16. The conductor is wound on the discharge traction wheel 16 and finally wound on the discharge traction wheel 11 and the conveying traction wheel 2 in sequence. The inclined setting of the line dividing wheel 15 can ensure that the conductor can be staggered on the discharge traction wheel 11 and the conveying traction wheel 2 for winding and traction. When the driven shaft 3 rotates, the line dividing wheel 15 and the limiting wheel 16 will not rotate with the driven shaft 3. The line dividing wheel 15 and the limiting wheel 16 cooperate to stagger the conductor on the discharge traction wheel 11 for winding, thereby realizing the function of limiting and dividing the conductor.

[0036] In some specific implementation schemes, a plurality of fixing holes are opened at the side end of the conveying traction wheel 2, and a fixing member 4 is abutted and connected in the fixing hole, the fixing member 4 is fixedly connected to the driven shaft 3, and the fixing member 4 is cooperatively connected to the discharging traction wheel 11, and the discharging traction wheel 11 and the conveying traction wheel 2 are respectively fixed on the driven shaft 3 through the fixing member 4. When the discharging traction wheel 11 and the conveying traction wheel 2 are overhauled, the staff can remove the fixing member 4, and then remove the discharging traction wheel 11 and the conveying traction wheel 2 on the driven shaft 3 respectively.

[0037] In some specific embodiments, the crimping assembly includes: a fixed bracket 12, a crimping frame 18 and a crimping wheel 20. The side end of the fixed bracket 12 is fixedly connected to the crimping frame 18. Both ends of the crimping wheel 20 are respectively rotatably connected to the crimping frame 18. The crimping wheel 20 cooperates with the discharge traction wheel 11. When the conductor is unloaded from the discharge traction wheel 11, the crimping wheel 20 supports the conductor, and the conductor rotates along the crimping frame 18 with the crimping wheel 20, so that the crimping wheel 20 achieves the function of limiting the conductor. The fixed bracket 12 is fixed on the high-speed conductor twisting equipment, and the support provided by the fixed bracket 12 is transmitted to the crimping wheel 20 through the crimping frame 18.

[0038] In some specific implementation schemes, a spring 19 is fixedly connected to the bottom end of the crimping frame 18. The spring 19 is elastic and is always in a compressed state. The spring 19 cooperates with the crimping frame 18. When the size of the conductor changes, the staff can adjust the angle of the crimping frame 18 to press the spring 19 to different degrees. The spring 19 transfers the elastic tension to the crimping wheel 20 through the crimping frame 18, thereby ensuring that the crimping wheel 20 always maintains a moderate holding force on the conductor.

[0039] In some specific implementation schemes, the discharging traction wheel 11 is connected with a conductive rail 13. The conductive rail 13 is provided with several groups and has side plates 14 fixedly connected at both ends. When the conductor is broken, the conductor will detach from the discharging traction wheel 11 and fall onto the conductive rail 13. The conductor connects the conductive rail 13 to form a circuit, so that the connected circuit of the conductive rail 13 activates an alarm to remind the staff that the conductor is broken.

[0040] Several embodiments of the present invention are described in detail above, but the embodiments of the present invention are not limited thereto and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
