Description

Technical Field

[0001] This utility model relates to the field of copper stranded wire technology, and in particular to a tension adjustment device for a stranding machine used in copper stranded wire production. Background Technology

[0002] A stranding machine for copper stranded wire production is a specialized production equipment used to strand multiple copper single wires into copper stranded wires. It is widely used in industries such as wire and cable, electrical equipment, communications, and power transmission, and is one of the core pieces of equipment in the deep processing of copper wires.

[0003] Patent CN219658456U discloses a copper wire stranding machine. It includes a base, a lead wire reel fixedly connected to the front top of the base, and a wire combining reel fixedly connected to the top surface of the base behind the lead wire reel, along with a stranding mechanism. When using this patent, copper wire passes through a lead wire hole on the lead wire reel mounted on the top surface of the base. A drive motor then rotates the output end, which in turn drives a second rotating rod to rotate within a bearing installed in a mounting hole on the side wall of the stranding base. The second rotating rod then drives the connecting reel and the stranding reel to rotate, thus stranding the wire. However, this existing patent lacks a tension adjustment function. Different wire diameters, strand counts, and materials of copper wire require different optimal tensions, which can easily lead to problems such as wire breakage, loose strands, or deformation due to uneven tension.

[0004] Therefore, there is a need for a tension adjustment device for copper stranded wire production stranding machines that can monitor tension in real time. Utility Model Content

[0005] In order to overcome the shortcomings of the existing patents mentioned above, which lack tension adjustment function and require different optimal tensions for copper wires of different diameters, strand numbers, and materials, and are prone to problems such as wire breakage, loose strands, or deformation due to uneven tension, this utility model provides a tension adjustment device for a stranding machine used in copper stranding production that monitors tension in real time.

[0006] To address the aforementioned problems, this utility model adopts the following technical solution: a tension adjustment device for a copper stranded wire production stranding machine, comprising a base plate, support seats, a stranding roller, a wire guide roller, a guide roller, and copper wire. Two support seats are fixedly connected to the base plate. The stranding roller is rotatably mounted on one support seat, and the wire guide roller is fixedly connected to the other support seat. A guide roller is fixedly connected to the stranding roller. The stranding roller has eight wire-passing holes, and the guide roller has the same eight wire-passing holes. Copper wire is threaded through two corresponding wire-passing holes between the stranding roller and the guide roller. The device also includes a fixing plate. The system comprises a tension sensor, a rotating shaft, a first guide wheel, a screw, a sliding plate, a second guide wheel, a mounting plate, and a control panel. Eight fixed plates are fixedly connected to the guide roller, and tension sensors are mounted on the fixed plates. A rotating shaft is rotatably mounted on the fixed plates, and the first guide wheel is fixedly connected to the rotating shaft. Eight guide grooves are formed on the guide roller, and eight screws are rotatably mounted on the guide roller. Sliding plates are threaded onto the screws, and second guide wheels are rotatably mounted on the sliding plates. A mounting plate is installed between two support seats, and a control panel is mounted on the mounting plate. The control panel is electrically connected to the tension sensor.

[0007] Furthermore, it also includes a servo motor and a pulley assembly. The servo motor is mounted on the base plate, and a pulley assembly is provided between the output shaft of the servo motor and the stranding roller.

[0008] Furthermore, it also includes a first mounting base, a first limiting wheel, a guide rod, a second mounting base, an elastic element, and a second limiting wheel. Multiple first mounting bases are fixedly connected to the stranding roller, and a first limiting wheel is rotatably mounted on the first mounting base. Multiple guide rods are fixedly connected to the stranding roller, and a second mounting base is slidably mounted on the guide rod. A second limiting wheel is rotatably mounted on the second mounting base. An elastic element is sleeved on the guide rod, and both ends of the elastic element are connected to the second mounting base and the stranding roller, respectively.

[0009] Furthermore, it also includes an audible and visual alarm, with eight audible and visual alarms installed on the guide roller.

[0010] Furthermore, a semi-circular through hole is provided on the support base.

[0011] Furthermore, a knob is fixedly connected to the screw.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. The tension of the copper wire is monitored in real time by a tension sensor. The tension sensor transmits the monitored tension value and displays it on the control panel, so as to obtain the copper wire tension data in real time. If the copper wire tension is too high or too low, the knob on the screw is rotated, and the screw drives the slide plate to move the second guide wheel, thereby adjusting the tension of the copper wire and avoiding problems such as wire breakage, loose strands or deformation caused by uneven tension.

[0013] 2. By starting the servo motor, the output shaft of the servo motor drives the stranding roller to rotate through the pulley assembly, so that the stranding roller runs at a set speed to ensure the uniformity and continuity of copper wire stranding.

[0014] 3. By passing the copper wire between the first limiting wheel and the second limiting wheel, the copper wire squeezes the second limiting wheel to move outward and the second mounting base to move outward, squeezing the elastic element. The elastic element then drives the second limiting wheel and the second mounting base to move inward, thereby holding the copper wire in place and preventing the copper wire from becoming loose or overly tight.

Detailed Implementation

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0022] Example 1: A tension adjustment device for a stranding machine used in copper stranding wire production, see reference. Figures 1-5As shown, the system includes a base plate 1, a support base 2, a stranding roller 3, a wire guide spool 301, a guide roller 4, and copper wire 6. The support base 2 is symmetrically mounted on the top of the base plate 1 via welding. The stranding roller 3 is rotatably mounted on the upper part of the support base 2 on the left. The wire guide spool 301 is fixedly connected to the upper part of the support base 2 on the right. The guide roller 4 is fixedly connected to the right side of the middle of the stranding roller 3. The stranding roller 3 passes through the guide roller 4 and the wire guide spool 301. Eight wire-passing holes 5 are evenly spaced on the right side of the stranding roller 3 in a circular arrangement. The guide roller 4 also has eight identical wire-passing holes 5 evenly spaced, with corresponding holes on the guide roller 4 and the stranding roller 3. Copper wire 6 is threaded through the two corresponding wire-passing holes 5 between the stranding roller 3 and the guide roller 4. The system also includes a fixing plate 7, a tension sensor 8, a rotating shaft 9, a first guide roller 10, a screw 12, a sliding plate 13, a second guide roller 14, a mounting plate 15, and a control panel. 16. Eight fixed plates 7 are evenly spaced and fixedly connected to the right side of the guide roller 4. Tension sensors 8 are installed on the fixed plates 7 by bolt connection. A rotating shaft 9 is rotatably installed on the fixed plates 7, passing through the tension sensors 8. A first guide wheel 10 is fixedly connected to the rotating shaft 9. Eight guide grooves 11 are evenly spaced on the right side of the guide roller 4. Eight screws 12 are evenly spaced and rotatably installed on the right side of the guide roller 4. The screws 12 are located in adjacent guide grooves 11. A sliding plate 13 is threaded on the screws 12. A second guide wheel 14 is rotatably installed on the sliding plate 13. The first guide wheel 10 is located to the right of the second guide wheel 14. Copper wire 6 is wound around the first guide wheel 10 and the second guide wheel 14. A mounting plate 15 is bolted between the front sides of the two support seats 2. A control panel 16 is bolted on the mounting plate 15. The control panel 16 is electrically connected to the tension sensors 8.

[0023] See Figure 3 As shown, it also includes an audible and visual alarm 25, and eight audible and visual alarms 25 are evenly spaced around the guide roller 4.

[0024] See Figure 1 and Figure 2 As shown, a semi-circular through hole is opened at the lower part of the support base 2.

[0025] See Figure 3 As shown, a knob is provided at the end of the screw 12 by welding.

[0026] When using this device, the copper wire 6 passes through the corresponding holes of the stranding roller 3 and the guide roller 4 to ensure that the copper wire 6 follows a consistent path during the stranding process. Then, the rotation of the stranding roller 3 achieves synchronous stranding of multiple strands of copper wire 6. During stranding, the copper wire 6 presses the first guide roller 10 and the second guide roller 14 to rotate and slide on their surfaces. The tension of the copper wire 6 is monitored in real time by the tension sensor 8. The tension sensor 8 transmits the monitored tension value and displays it on the control panel 16, thereby enabling real-time acquisition of the tension data of the copper wire 6. If the tension of the copper wire 6 is too high or too low, the knob on the screw 12 is rotated. The screw 12 drives the slide plate 13 to move along the guide groove 11. The slide plate 13 drives the second guide roller 14 to move, thereby adjusting the pressure of the second guide roller 14 on the copper wire 6, thus adjusting the tension of the copper wire 6, ensuring stable tension during the stranding process, and avoiding problems such as wire breakage, loose strands, or deformation caused by uneven tension. When the tension sensor 8 detects abnormal tension, the control panel 16 triggers the audible and visual alarm 25 to issue a warning.

[0027] Example 2: Based on Example 1, refer to Figure 2 As shown, it also includes a servo motor 17 and a pulley assembly 18. The servo motor 17 is installed on the top left side of the base plate 1. The pulley assembly 18 is provided between the output shaft of the servo motor 17 and the stranded roller 3. The pulley assembly 18 consists of two pulleys and a flat belt. The two pulleys are respectively set on the output shaft of the servo motor 17 and the stranded roller 3, and the flat belt is wound around the two pulleys.

[0028] When it is necessary to strand the copper wire 6, the servo motor 17 is started. The output shaft of the servo motor 17 drives the stranding roller 3 to rotate through the pulley assembly 18, so that the stranding roller 3 runs at a set speed to ensure the uniformity and continuity of the stranding of the copper wire 6.

[0029] See Figure 1 and Figure 5 As shown, it also includes a first mounting base 19, a first limiting wheel 20, a guide rod 21, a second mounting base 22, an elastic element 23, and a second limiting wheel 24. Eight first mounting bases 19 are fixedly connected at even intervals on the left and right sides of the stranded roller 3. The first limiting wheel 20 is rotatably mounted on the first mounting base 19. Eight guide rods 21 are fixedly connected at even intervals on the left and right sides of the stranded roller 3. The second mounting base 22 is slidably mounted on the guide rod 21. The second limiting wheel 24 is rotatably mounted on the second mounting base 22. An elastic element 23 is sleeved on the guide rod 21. The two ends of the elastic element 23 are respectively connected to the second mounting base 22 and the stranded roller 3. The copper wire 6 is located between the adjacent first limiting wheel 20 and second limiting wheel 24.

[0030] When the copper wire 6 is passed through the stranding roller 3, it passes between the first limiting wheel 20 and the second limiting wheel 24. The copper wire 6 squeezes the second limiting wheel 24 and moves it outward. The second limiting wheel 24 drives the second mounting base 22 to move outward and squeeze the elastic member 23. The elastic member 23 is compressed and quickly rebounds. The elastic member 23 then drives the second limiting wheel 24 and the second mounting base 22 to move inward, thereby holding the copper wire 6 in place and preventing the copper wire 6 from becoming loose or overly tight.

[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
