Description

Technical Field

[0001] This invention relates to the field of high-speed conductor stranding equipment technology, and more specifically to a traction device for high-speed conductor stranding equipment. Background Technology

[0002] High-speed conductor stranding equipment is a type of mechanical equipment specifically used in the production of wires and cables. It can achieve high-speed stranding of different types of conductors. These devices typically have high efficiency, high precision, and good stability, and are suitable for processing various soft or hard conductor wires.

[0003] In the prior art, when high-speed conductor stranding equipment strands conductors, a traction device is often used to guide the stranded conductors. The traction device mainly consists of a traction wheel and a motor. The traction wheel has a circular groove, and the conductor is wrapped around the circular groove. The motor drives the traction wheel to rotate, thereby guiding the conductors.

[0004] However, when the conductor is wrapped around the circular groove, only the bottom end of the conductor abuts against the circular groove, and the cross-section of the conductor is circular. This causes the conductor to slide when it rotates through the traction wheel, thus affecting the roundness of the conductor after it passes through the traction device. Summary of the Invention

[0005] The purpose of this invention is to provide a traction device for a high-speed conductor stranding equipment, so as to solve the technical problem in the prior art where the circular groove of the traction wheel causes the conductor to slide and translate on the traction wheel.

[0006] The technical problem to be solved by this invention can be achieved through the following technical solution:

[0007] A traction device for a high-speed conductor stranding apparatus, comprising:

[0008] The motor is connected to a transmission assembly, which is connected to two sets of driven shafts.

[0009] The discharge traction wheel is fixedly connected to the driven shaft. The discharge traction wheel is connected to a wire pressing assembly. The discharge traction wheel has a limit groove around its axis.

[0010] The conveying traction wheel is located at the bottom of the discharge traction wheel and is fixedly connected to the driven shaft. The conveying traction wheel has a limit groove around its axis, and the cross-section of the limit groove is V-shaped.

[0011] As a further scheme of the present application: the transmission assembly comprises: a driven wheel, a driving wheel and a driving shaft, the outer wall of the driving wheel is connected with a driving belt through meshing teeth, the driving wheel is fixedly connected with the driving shaft, the driving belt is connected with the motor through meshing teeth, the driven wheel is provided with two groups and is connected with a driven belt through meshing teeth on the outer wall, the driven wheel is fixedly connected with the driven shaft, and the driven belt is connected with the driving shaft through meshing teeth.

[0012] As a further scheme of the present application: the driven belt is connected with a tensioning piece.

[0013] As a further scheme of the present application: the outer wall of the driven shaft is connected with a line dividing wheel, the top end of the line dividing wheel is arranged in a direction away from the conveying traction wheel, a plurality of balls are arranged between the line dividing wheel and the driven shaft, the line dividing wheel is connected with a limiting wheel, the balls are connected with the inner wall of the line dividing wheel through rolling, and the limiting wheel is connected with the discharging traction wheel.

[0014] As a further scheme of the present application: the side end of the conveying traction wheel is provided with a plurality of fixing holes, the fixing holes are connected with a fixing piece through abutting, the fixing piece is fixedly connected with the driven shaft, and the fixing piece is connected with the discharging traction wheel.

[0015] As a further scheme of the present application: the pressing assembly comprises: a fixed support, a pressing frame and a pressing wheel, the side end of the fixed support is fixedly connected with the pressing frame, the two ends of the pressing wheel are rotatably connected with the pressing frame, and the pressing wheel is connected with the discharging traction wheel.

[0016] As a further scheme of the present application: the bottom end of the pressing frame is fixedly connected with a spring, the spring has elasticity and is always in a compressed state, and the spring is connected with the pressing frame.

[0017] As a further scheme of the present application: the discharging traction wheel is connected with a conductor rail, the conductor rail is provided with a plurality of groups and is fixedly connected with a side plate at two ends.

[0018] The present application has the following beneficial effects:

[0019] 1. When the conductor is stranded by the high-speed conductor stranding equipment, the motor runs and drives the driven shaft to rotate through the transmission assembly. The two driven shafts drive the conveying traction wheel and the discharge traction wheel to rotate respectively. The conductor is wound once on the conveying traction wheel and once on the discharge traction wheel, thus tractioning the conductor. The rotation of the conveying traction wheel and the discharge traction wheel causes the conductor to rotate and move. When the conductor is detached from the discharge traction wheel, the wire clamping assembly limits the conductor to prevent it from loosening on the discharge traction wheel. When the conductor is being pulled, it is held against the limiting groove, with both ends of the conductor abutting against the inner walls of the limiting groove. The shape of the limiting groove limits the two ends of the conductor in the horizontal direction, thus preventing the conductor from shifting in the limiting groove and ensuring the stability of the conductor when being pulled in the limiting groove, thereby ensuring the roundness of the conductor during traction.

[0020] 2. The shape of the limiting groove can limit conductors of different diameters, further improving the applicability of the limiting groove. When the traction device pulls the conductor, the limiting groove reduces the error when the conductor is discharged. Thus, the length of the conductor being pulled 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 conductors are stranded, high-speed conductor stranding equipment often has a high speed, and the limiting groove can ensure the precision of the traction device in pulling the conductor.

[0033] In some specific embodiments, the transmission assembly comprises: a driven wheel 5, a driving wheel 8 and a driving shaft 10, the outer wall of the driving wheel 8 is connected with a driving belt 9, the driving wheel 8 is fixedly connected with the driving shaft 10, the driving belt 9 is connected with the motor 1, the driven wheel 5 is provided with two groups and the outer wall is connected with a driven belt 6, the driven wheel 5 is fixedly connected with the driven shaft 3, the driven belt 6 is connected with the driving shaft 10, when the motor 1 operates, 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 wheel 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 drive the conveying traction wheel 2 and the discharge traction wheel 11 to rotate respectively.

[0034] In some specific embodiments, the driven belt 6 is matched with a tensioning piece 7, when the driven belt 6 is used for a long time, it will be loose, the tensioning piece 7 can abut against the driven belt 6, ensuring that the driven belt 6 is tightly sleeved on the driven wheel 5, so that the driven belt 6 stably drives the driven wheel 5 to rotate.

[0035] In some specific embodiments, the outer wall of the driven shaft 3 is sleeved with a line distribution wheel 15, the top end of the line distribution wheel 15 is inclinedly arranged in a direction away from the conveying traction wheel 2, a plurality of balls 17 are arranged between the line distribution wheel 15 and the driven shaft 3, the line distribution wheel 15 is cooperatively connected with a limiting wheel 16, the balls 17 are in rolling connection with the inner wall of the line distribution wheel 15, and the limiting wheel 16 cooperates with the discharge traction wheel 11.

The inclined arrangement of the line distribution wheel 15 can ensure that the conductor can be misaligned and wound on the discharge traction wheel 11 and the conveying traction wheel 2 for traction. When the driven shaft 3 rotates, the line distribution wheel 15 and the limiting wheel 16 do not rotate with the driven shaft 3. The cooperation of the line distribution wheel 15 and the limiting wheel 16 can misalign the conductor and wind it on the discharge traction wheel 11, thereby achieving the function of limiting and distributing the conductor.

[0037] In some specific embodiments, the line pressing assembly comprises a fixed support 12, a line pressing frame 18 and a line pressing wheel 20. The side end of the fixed support 12 is fixedly connected with the line pressing frame 18, and the two ends of the line pressing wheel 20 are rotatably connected with the line pressing frame 18. The line pressing wheel 20 cooperates with the discharge traction wheel 11. When the conductor is discharged from the discharge traction wheel 11, the line pressing wheel 20 abuts against the conductor, and the conductor rotates along the line pressing frame 18 with the line pressing wheel 20, so that the line pressing wheel 20 achieves the function of limiting the conductor. The fixed support 12 is fixed on the high-speed conductor stranding equipment, and the supporting function of the fixed support 12 is transmitted to the line pressing wheel 20 through the line pressing frame 18.

[0038] In some specific embodiments, the bottom end of the line pressing frame 18 is fixedly connected with a spring 19. The spring 19 has elasticity and is always in a compressed state. The spring 19 cooperates with the line pressing frame 18. When the size of the conductor changes, the angle of the line pressing frame 18 can be adjusted by the worker, so that the spring 19 is in a state of being pressed to different degrees, and the spring 19 transmits the elastic tension to the line pressing wheel 20 through the line pressing frame 18, so that the line pressing wheel 20 always provides a moderate abutting force to the conductor.
