Description

Technical Field

[0001] The utility model relates to the field of power cable production equipment, in particular to a twisted-pair cable manufacturing device. Background Art

[0002] In known twisted-pair cable manufacturing equipment, an operator secures one end of a pair of wires in a fixture. The operator then moves to the other end of the wires and secures the other end of the wires in a corresponding fixture. The operator activates a motor to rotate the fixture securing one end of the wire pair, twisting the wires together to form a twisted-pair cable.

[0003] From the manufacturing process of the twisted-pair cable described above, it can be seen that the operator needs to move to complete the clamping and fixing of the two ends of the paired wires, and then needs to move again to wrap the two ends of the twisted-pair cable with tape, and finally remove the completed twisted-pair cable from the equipment.

In addition, when the operator clamps and fixes the two ends of the paired wires, after clamping and fixing one end, the other end needs to be fixed to another clamp. This requires that the paired wires be tightened, which is quite difficult. Summary of the Invention

DETAILED DESCRIPTION

[0051] The present invention is further described below in conjunction with specific embodiments and accompanying drawings. More details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can obviously be implemented in a variety of other ways different from the description. Those skilled in the art can make similar generalizations and deductions based on actual application situations without violating the connotation of the present invention. Therefore, the scope of protection of the present invention should not be limited by the content of this specific embodiment.

[0052] In the first embodiment of the present invention, Figure 1 As shown, the twisted pair cable manufacturing device includes: a frame 1, a wire supply part 2, a partition 3, a traction and twisting part 4, and a tape winding part 5. The wire supply part 2, the partition 3, the tape winding part 5 and the traction and twisting part 4 are arranged in sequence on the frame 1 along the forward direction of the wire 11.

[0053] like Figure 2 、 Figure 3 As shown, the wire supply part 2 includes: a first guide wheel 21, a second guide wheel 22, a first tension wheel 23, a third guide wheel 24, a fourth guide wheel 25, and a second tension wheel 26. The first guide wheel 21, the second guide wheel 22 and the first tension wheel 23 and the third guide wheel 24, the fourth guide wheel 25 and the second tension wheel 26 are relatively vertically arranged on the frame 1 with the extension line of the forward direction of the wire 11 as the center, wherein the first tension wheel 23 and the second tension wheel 26 are respectively arranged on the first guide wheel 21, the second guide wheel 22 and the third guide wheel 24, the fourth guide wheel 25 away from each other On the outside of the first guide wheel 21, the second guide wheel 22 and the first tensioning wheel 23 are used to guide one wire 11 to pass through the traction and twisting part 4 in a U-shaped trajectory, and the third guide wheel 24, the fourth guide wheel 25 and the second tensioning wheel 26 are used to guide the other wire 11 to pass through the traction and twisting part 4 in a U-shaped trajectory. The tensile forces applied by the first tensioning wheel 23 and the second tensioning wheel 26 to the two wires 11 respectively keep the two wires 11 in a tightened state at all times when the traction and twisting part 4 pulls the two wires 11, so as to facilitate the twisting of the two wires 11 to manufacture the twisted pair cable 12.

[0054] like Figure 2 、 Figure 3 As shown, the partition 3 has a wire channel 31 extending along the direction of advancement of the wires 11. The wire channel 31 is used to restrict the two wires 11 supplied by the wire supply part 2 to pass through the wire channel 31.

[0055] like Figure 2 、 Figure 3 、 Figure 4As shown, the traction twisting part 4 includes: a slide rail 41, a slide 42, a screw 43, a rotating clamp 44, a straight rack 45, a transmission mechanism 46, and a motor 47. The slide rail 41 is longitudinally arranged on the frame 1, and the slide 42 is arranged on the slide rail 41 through a slide groove at the lower end. The slide 42 is engaged with the screw 43 arranged parallel to the slide rail 41 through a nut at one end. The rotating clamp 44 is arranged at the other end of the slide 42 through a circular shaft. 4 has a circular axis that coincides with an extension line of the forward direction of the wire. The straight rack 45 is arranged along the lower part of the slide rail 41 toward the rotating clamp 44. The transmission mechanism 46 is arranged in the slide 42 and consists of a gear 461, a worm 462 and a worm wheel 463. The gear 461 at the lower end of the transmission mechanism 46 engages with the straight rack 45, and its worm wheel 462 is mounted on the circular axis of the rotating clamp 44. The screw 43 is driven by a motor 47 arranged at one end of the frame 1.

[0056] like Figure 2 、 Figure 3 As shown, the belt winding portion 5 is composed of a first belt winding mechanism 51, a second belt winding mechanism 52 and a cutting mechanism 53. The first belt winding mechanism 51, the second belt winding mechanism 52 and the cutting mechanism 53 are mounted above the extension line of the forward direction of the electric wire 11 through a mounting column 6, and vertical lifting and lowering are achieved through a slide groove on the mounting column 6. The cutting mechanism 53 is located between the first belt winding mechanism 51 and the second belt winding mechanism 52 which are spaced apart.

[0057] As can be seen from the first embodiment of the present invention, the two wires 11 enter the traction and twisting part 4 through the wire channel 31 provided on the partition 3 under the guidance of the multiple guide wheels of the wire supply part 2. The rotating clamping claw 44 of the traction and twisting part 4 clamps and fixes one end of the two wires 11. The motor 47 is started and drives the slide 42 to move along the slide rail 41 through the screw 43, thereby driving the rotating clamping claw 44 to pull the two wires 11 along the slide rail 41. In this process, the tensile force applied to the two wires 11 by the first tensioning wheel 23 and the second tensioning wheel 26 is respectively applied to the two wires 11, so that the two wires 11 are always in a taut state during the traction process. At the same time, the rotating clamping claw 44 is driven to rotate through the transmission mechanism 46, so that the two wires 11 are always in a taut state during the traction process. The wires 11 are twisted, and when they reach the set length, the motor 47 stops, the belt winding part 5 descends, and the first belt winding mechanism 51 and the second belt winding mechanism 52 respectively wind the two twisted wires 11 at two locations close to the partition 3, and then the cutting mechanism 53 cuts the two wires 11 between the two locations that have been wrapped with the belt to form a twisted pair cable 12 of the set length. Finally, the rotating jaws 44 open and the belt winding part 5 ascends and separates from the formed twisted pair cable 12. The twisted pair cable 12 falls due to its own gravity and is collected. The motor 47 starts, driving the slide 42 to move toward the partition 3, and the rotating jaws 44 clamp and fix one end of the two wires 11 to start the manufacture of the next twisted pair cable 12.

[0058] Through this technical solution, after the two wires 11 are clamped and fixed at one end, they can be twisted together to form a twisted pair cable 12 during the movement process. There is no need to clamp and fix both ends of the two wires 11 at the same time, which can save time and improve production efficiency. At the same time, the tensile force applied by the first tensioning pulley 23 and the second tensioning pulley 26 to the two wires 11 respectively ensures that the two wires 11 are always in a taut state when being pulled, thereby avoiding the kinking phenomenon that may occur when the two wires 11 are twisted. In addition, the first tape winding mechanism 51 and the second tape winding mechanism 52 of the tape winding part 5 can simultaneously perform tape winding on the two twisted wires 11 and one end of the two wires 11 to be twisted. Subsequently, the tape winding part 5 and the rotating clamp 44 release the already formed twisted pair cable 12 and let it fall by its own weight to be collected, which also saves a lot of time and improves production efficiency. In addition, through this technical solution, the automation of the manufacture of the twisted pair cable 12 can be achieved, while improving production efficiency and reducing the labor intensity of the operators.

[0059] It should be pointed out that, when manufacturing the twisted-pair cable 12 , the present technical solution can obtain the twisted-pair cable 12 of a desired length within the length range of the slide rail 41 , thereby further improving the utilization rate of the equipment.

The tensile forces applied by the first tensioning wheel 23 and the second tensioning wheel 26 to the two wires 11 respectively keep the two wires 11 in a tightened state at all times when the traction and twisting part 4 pulls the two wires 11, so as to facilitate the twisting of the two wires 11 to manufacture the twisted pair cable 12.

[0062] like Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 As shown, the partition 3 has a wire channel 31 extending along the direction of advancement of the wires 11. The wire channel 31 is used to restrict the two wires 11 supplied by the wire supply part 2 to pass through the wire channel 31.

The servo motor 48 is used to drive the rotating clamp 44 to rotate. The setting of the servo motor 48 can effectively control the rotation speed of the rotating clamp 44, thereby obtaining a twisted pair cable 12 with a desired twist density.
