Description

Technical Field

[0001] This invention relates to the field of cable production technology, and in particular to a cable stranding device. Background Technology

[0002] Cables are often not composed of a single-strand metal core, but rather of a cable busbar and multiple cable daughter wires twisted together. Manual twisting of the cable busbar and daughter wires is inefficient, and the resulting loose connection between them significantly impacts the cable's usability and reduces its signal transmission efficiency. Therefore, a cable twisting device is needed to complete the twisting process, ensuring both efficiency and quality in cable production. This solution specifically addresses cable twisting devices. Existing cable twisting devices suffer from friction between the cable busbar and daughter wires and the device itself, leading to... The cable sub-wires generate heat due to friction. When stranding is completed at a high temperature, thermal expansion and contraction can cause the stranding to loosen after cooling, affecting the quality of the cable. Furthermore, the cable sub-wires are constantly moving during stranding, making it impossible to adjust their tension. When the cable sub-wires become excessively loose, it also affects the stranding quality. Since cable sub-wires consist of multiple strands, if a single strand becomes detached or misaligned during stranding, it may not be detected in time, leading to the cable being stranded with missing sub-wires, increasing the defect rate. Subsequent processing requires re-separating the cable sub-wires and the main cable for re-stranding, which is quite troublesome. Summary of the Invention

[0022] like Figures 1-6 As shown, a cable production stranding device includes a base plate 1, a busbar feeding roller 2 is installed at the rear of the top of the base plate 1, a connecting housing 24 is fixedly installed at the top of the base plate 1 and in front of the busbar feeding roller 2, a stranding motor 12 is installed at the bottom of the back of the connecting housing 24, a wiring wheel 3 is movably installed through the front and back of the connecting housing 24 near the top, a sub-wire feeding roller 9 is movably installed between the inner walls of the front and rear ends of the wiring wheel 3, and a plurality of alarms 10 are fixedly installed on the outer ring of the wiring wheel 3 near the front end;

[0023] Several tension monitoring and adjustment components 11 are mounted on the front of the wiring wheel 3. Each tension monitoring and adjustment component 11 includes a mounting frame 1101. Adjustment wheels 1102 are movably mounted between the two sides of the mounting frame 1101. Limiting guide rods 1103 are movably mounted on both sides of the upper and lower ends of the mounting frame 1101. An adapter seat 1106 is movably mounted between the two limiting guide rods 1103 near the top. A support guide rod 1104 is movably mounted centrally at the upper and lower ends of the adapter seat 1106. A pressure sensor 1107 is fixedly installed at the bottom end of the rod 1104. The outer rings of the limiting guide rod 1103 and the supporting guide rod 1104 are both equipped with springs 1105. The two ends of two springs 1105 are fixedly connected to the bottom surface of the adapter 1106 and the top surface of the mounting frame 1101, respectively. The two ends of the other spring 1105 are fixedly connected to the bottom surface of the adapter 1106 and the top surface of the pressure sensor 1107, respectively. The back of the adapter 1106 is fixedly connected to the front of the wiring wheel 3.

[0024] A stranding frame 4 is fixedly installed at the top of the base plate 1 and in front of the wiring wheel 3. A stranding wheel 13 is movably installed near the top of the front and back of the stranding frame 4. Several guide wheels 14 are movably installed on both the front and back of the stranding wheel 13. A wire limiting tube 15 is fixedly installed in the center of the front and back of the stranding wheel 13. Sub-wire limiting holes 16 are opened in the center of the front and rear ends of the wire limiting tube 15 and the front and rear ends of the wiring wheel 3. A wire guide roller 17 is movably installed inside the sub-wire limiting hole 16. Several infrared temperature sensors 18 are fixedly installed on the outer ring of the front of the wire limiting tube 15. After the cable sub-wire passes through the stranding wheel 13, it contacts the guide wheel 14. During the movement of the cable sub-wire, the guide wheel 14 reduces the friction force on the cable sub-wire and changes the direction of the cable sub-wire, making it easier for the cable sub-wire to pass through the sub-wire limiting hole 16 on the front of the wire limiting tube 15.

[0025] A cooling box 5 is fixedly installed at the top of the base plate 1 and in front of the wire limiting tube 15. A cooling air box 19 is fixedly installed through the top of the cooling box 5. The cooling air box 19 draws in air and lowers the air temperature, and then blows it out through the cooling box 5 to cool the cable sub-wire.

[0026] An adjustable base 6 is fixedly installed at the top of the base plate 1 and in front of the cooling box 5. A cable tie bracket 20 is movably installed at the top of the adjustable base 6. A cable tie 21 is installed in the center of the front and rear ends of the cable tie bracket 20. A lead screw 22 is movably installed inside the adjustable base 6 and through the front of the adjustable base 6. The lead screw 22 is threadedly connected to the cable tie bracket 20. After the cable busbar and cable sub-wire pass through the cable tie 21, they are twisted into a single wire. At the same time, rotating the lead screw 22 makes it easy to adjust the position of the cable tie bracket 20, and thus adjust the position of the cable tie 21, so as to adjust the twist pitch as needed.

[0027] A busbar take-up roller 7 is fixedly installed at the top of the base plate 1 and in front of the adjusting base 6. A take-up motor 23 is fixedly installed on one side of the busbar take-up roller 7 near the top. A PLC control box 8 is fixedly installed at the top of the base plate 1 in the center of one side.

[0028] The alarm 10, twisted wire motor 12, infrared temperature sensor 18, cooling air box 19 and take-up motor 23 are all electrically connected to the PLC control box 8. The PLC control box 8 receives electrical signals and can issue commands to control the operation of electrical components.

[0029] The internal structure of the connecting housing 24 is equipped with a transmission mechanism, and the wiring wheel 3 is connected to the stranded wire motor 12 through the transmission mechanism. When the stranded wire motor 12 starts, it drives the wiring wheel 3 to rotate through the transmission mechanism, thus stranding the cable sub-wires onto the outside of the cable busbar.

[0030] The positions of the adjusting wheel 1102 and the sub-line limiting hole 16 on the front of the wiring wheel 3 correspond to each other. In the initial state, the monitoring value of the pressure sensor 1107 is zero. Each pressure sensor 1107 corresponds to an alarm 10 and a sub-line feeding roller 9. When the adjusting wheel 1102 is pressed by the cable sub-line, the pressure sensor 1107 monitors the pressure value. When the cable sub-line is removed from the adjusting wheel 1102, the monitoring value of the pressure sensor 1107 is zero due to the loss of pressure, and the alarm 10 sounds an alarm.

[0031] Several air ducts are provided in the inner ring of the cooling box 5, and the number and position of the air ducts correspond to the position of the sub-line limiting hole 16 on the front of the limiting shaft tube 15. The air outlet of the cooling air box 19 is connected to the interior of the cooling box 5. After the cooling air box 19 sends low-temperature air into the air duct, the low-temperature air is blown out through the air duct to cool the cable sub-line.

[0032] It should be noted that the present invention is a cable production stranding device. In use, the cable busbar is first placed on the busbar feeding roller 2, and the cable sub-wire is placed on the sub-wire feeding roller 9. Then, the cable busbar is pulled out and passes through the wiring wheel 3, the wire limiting tube 15, the cooling box 5, and the cable bundler 21 in sequence. The cable sub-wire is then passed through the sub-wire limiting hole 16 on the wiring wheel 3, the stranding wheel 13, the sub-wire limiting hole 16 on the front of the wire limiting tube 15, the cooling box 5, and the cable bundler 21 in sequence. The cable sub-wire contacts the guide wheel 14, the conductor roller 17, and the adjusting wheel 1102. Then, both the cable busbar and the cable sub-wire are wound onto the busbar take-up roller 7.

[0033] After the cable busbar and cable sub-line are installed, the circuit connected to the pressure sensor 1107 is connected through the PLC control box 8. The number and position of the connection are determined according to the number and position of the sub-line feed rollers 9 where the cable sub-line is located. At the same time, the temperature threshold is set. Then, the screw 22 is rotated to drive the wire bundle bracket 20 and the wire bundler 21 to move synchronously. The stranding pitch is adjusted according to the requirements. After the adjustment is completed, the stranding motor 12 and the take-up motor 23 are started.

[0034] The take-up motor 23 drives the cable busbar and cable sub-wire to move. At the same time, the stranding motor 12, in conjunction with the transmission mechanism inside the connecting housing 24, drives the wiring wheel 3 to rotate. During the rotation of the wiring wheel 3, the cable sub-wire is stranded to the outside of the cable busbar. Since the cable sub-wire is in a taut state, the adjusting wheel 1102 is pressed by the cable sub-wire, and the pressure is monitored by the pressure sensor 1107 through the mounting frame 1101. The spring 1105 is in a compressed state and automatically adjusts the tension of the cable sub-wire according to the magnitude of the pressure to prevent the cable sub-wire from becoming too loose. When the cable sub-wire is detached from the adjusting wheel 1102, the spring 1105 drives the mounting frame 1101 and the adjusting wheel 1102 back to the initial position. The pressure sensor 1107 detects a value of zero, and the corresponding alarm 10 sounds an alarm. The cable production stranding device stops operating, reminding the staff to replace the cable sub-wire and return the cable sub-wire to its original position.

[0035] During the twisting process of the cable busbar and cable sub-wire, the temperature of the cable sub-wire is monitored by the infrared temperature sensor 18. When the monitored temperature exceeds the set temperature threshold, it indicates that the moving speed of the cable sub-wire is too fast and the frictional heat generation increases. At this time, the speed of the take-up motor 23 is reduced, and the moving speed of the cable sub-wire and the cable busbar is reduced synchronously. At the same time, the cooling air box 19 is started and draws in ambient air to cool the air inside. After the low-temperature air enters the cooling box 5, it is blown onto the cable sub-wire through the air duct on the inner wall of the cooling box 5 to cool it down, so as to prevent the cable sub-wire from completing the twisting process at a high temperature.

[0036] The beneficial effects that can be achieved by the above embodiments of the present invention include:

[0037] 1. The present invention sets up a tension monitoring and adjustment component. When the cable sub-wire presses against the adjustment wheel, the pressure is transmitted to the mounting frame, causing the spring to be compressed. The mounting frame is limited by the limiting guide rod. At the same time, the spring adjusts the tension of the cable sub-wire according to the pressure, so as to prevent the cable sub-wire from becoming too loose and coming off the adjustment wheel, which would affect the stranding effect.

[0038] 2. By setting up a tension monitoring and adjustment component in conjunction with an alarm, when the cable sub-wire comes off the adjustment wheel, the adjustment wheel loses the pressure of the cable sub-wire, and under the action of the spring, the mounting bracket and adjustment wheel reset, the monitoring value of the pressure sensor is zero, at which point the alarm sounds, the cable production stranding device reminds the staff to replace the cable sub-wire, and resets the cable sub-wire to prevent the cable from completing stranding without the cable sub-wire.

[0039] 3. By setting up an infrared temperature sensor, a cooling fan box, and a cooling box, when the temperature monitored by the infrared temperature sensor exceeds the set temperature threshold, the speed of the take-up motor is reduced, thereby reducing the moving speed of the cable sub-wire and the cable busbar. At the same time, the cooling fan box starts to draw in ambient air and cool it inside. After the low-temperature air enters the cooling box, it is blown out through the air duct on the inner wall to reduce the temperature of the cable sub-wire and prevent the cable sub-wire from completing twisting at a high temperature, which would cause it to loosen when the temperature drops.
