Description

Technical Field

[0001] This utility model belongs to the field of stranding machine technology, specifically a tin-plated stranded copper wire stranding machine. Background Technology

[0002] Early stranding machines had slow production speeds when producing tin-plated stranded copper wire, making it difficult to meet the needs of large-scale production. Traditional stranding machines were also insufficient in controlling the stranding precision and uniformity of tin-plated stranded copper wire, which could lead to problems such as loose strands and uneven spacing of the stranded wire cores, affecting the electrical and mechanical properties of the product.

[0003] Meanwhile, the European-style high-speed stranding machine with announcement number CN210743684U is disclosed, including a stranding machine body, a take-up reel on the stranding machine body, symmetrical stranded bows on the outer side of the take-up reel, wire guide grooves installed on the symmetrical stranded bows, and first guide rollers installed at both ends of the symmetrical stranded bows. The stranding machine body is also equipped with a servo motor, and a transmission device is installed at the bottom of the servo motor. A take-up reel synchronous pulley is fixed on the take-up reel.

[0004] The aforementioned European-style high-speed stranding machine can only improve the stranding process by making the stranding smoother, with less resistance and faster speed. However, it cannot control the stranding speed, which leads to an inability to flexibly adjust according to different specifications and process requirements. This results in inconsistent pitch and substandard tightness of each stranded cable segment, affecting the product's flexibility, tensile strength, conductivity, and other properties during use.

[0005] Therefore, a tin-plated hinged copper wire stranding machine is proposed to address the above problems. Utility Model Content

The lower side of the transmission line 13 is fixed to the upper side of the PLC control device 10.

[0030] A hollow rectangular block 3 is fixedly provided in the middle of the upper end face of the base 1. A perforated circular plate 9 is fixedly provided inside the upper side of the hollow rectangular block 3 to prevent transmission entanglement.

[0031] A wire passage 4 is fixedly provided on the left side of the middle of the upper end face of the base 1, and a wire break alarm device 5 is fixedly provided on the upper left side of the wire passage 4 to serve as a warning.

[0032] A cuboid 6 is fixed on both the front and rear sides of the left end of the base 1. A take-up roller 7 is rotatably mounted inside the cuboid 6. A rotating shaft 15 is fixed on the front side of the take-up roller 7. A motor 8 is fixed on the front side of the rotating shaft 15 to provide power. The motor 8 is fixed to the cuboid 6.

[0033] A control panel 11 is fixedly installed on the upper right side of the PLC control device 10, and a control button 12 is fixedly installed on the lower right side of the PLC control device 10 for adjustment.

[0034] The working principle and process of a tin-plated hinged copper wire stranding machine: This tin-plated hinged copper wire stranding machine uses a base 1 as its basic support structure. A PLC control device 10 precisely controls each key component. A variable frequency motor 14 drives a gear transmission system to achieve synchronous wire feeding operations of multiple wire feeding devices 17. Simultaneously, a take-up roller 7 completes the wire winding. Throughout the process, a wire breakage alarm device 5 monitors the wire status in real time to ensure stable, efficient, and safe stranding operations. The operator connects the power supply, turns on the tin-plated hinged copper wire stranding machine, and views the initial status of the equipment, such as the parameters of the variable frequency motor 14 and the amount of transmission line 13, through the control screen 11 on the upper right side of the PLC control device 10. The control button 12 on the lower right side is used to input specific working parameters, including the speed of the variable frequency motor 14, the winding speed of the take-up roller 7, and the expected strand length. After setting, press the start button, and the PLC control device 10 will start sending start commands to each component. The PLC control device 10 transmits control signals to the frequency converter 16 through the transmission line 13. The frequency converter 16 adjusts the output frequency according to the preset parameters, thereby precisely controlling the speed of the variable frequency motor 14. After the variable frequency motor 14 starts, it drives the shaft 15 connected to it to rotate. The shaft 15 further drives the cylinder 19 in the middle of the left side of the fixed cylinder 21 to rotate, causing the large gear 20 fixed on the left side of the cylinder 19 to start rotating. The large gear 20 and the five small gears around it rotate together. The gears 18 mesh with each other, causing the pinions 18 to rotate synchronously. Since each pinion 18 has a wire feeding device 17 installed on its left side, the rotation of the pinions 18 causes the wire feeding device 17 to release tin-plated hinged copper wire. The wire released from the wire feeding device 17 enters the hollow rectangular block 3, passes through the perforated circular plate 9 on its upper side. The perforated circular plate 9 serves to organize and guide the multiple wires, ensuring that the wires are arranged in an orderly manner and preventing them from tangling. The organized wires are then transmitted to the take-up device through the wire passage 4. At the wire passage 4, the wire breakage alarm device 5 uses an internal optical sensor to monitor the passing wires in real time. Once a wire breakage is detected, the wire breakage alarm device 5 will immediately issue an audible and visual alarm signal to remind the operator to handle the situation promptly. (Base 1) The motor 8 inside the cuboid 6 on the front and rear sides of the left end starts, driving the connected rotating shaft 15 to rotate. The rotating shaft 15 drives the take-up roller 7 to rotate. The take-up roller 7 winds up the wire passing through the wire inlet 4 at a preset speed, twisting multiple tin-plated stranded copper wires together to form a stranded wire product that meets the requirements. When the preset stranded wire length is reached, the PLC control device 10 automatically issues a stop command, stopping the operation of the frequency conversion motor 14 and the motor 8 in sequence. The take-up roller 7 stops rotating, the stranding work is completed, the operator turns off the power, removes the stranded wire from the take-up roller 7, and cleans and inspects the equipment, such as cleaning up debris around the wire release device 17 and checking whether the connections of each component are loose, in preparation for the next operation.
