Description

Technical Field

[0001] The invention relates to the technical field of wire twisting machines, and in particular to a wire twisting device controlled by cable tension. Background Art

[0002] During the production process of battery cables, a stranding machine is generally used to strand the battery cores so that multiple battery core conductors are twisted into one strand to meet the process requirements of the cable. The cable stranding machine generally uses a turntable as a carrier. The turntable is provided with multiple reels, and the reels are loaded with battery cores. The main shaft rotates the turntable, and multiple strands of battery cores are twisted around the center of the turntable and pulled out from the center of the turntable.

[0003] The patent with application number CN2023208278289 provides a tension-controllable cable processing stranding machine, including a base, a rotating disk, a stranding drive mechanism and a tension adjustment mechanism. The rotating disk, the stranding drive mechanism and the tension adjustment mechanism are all arranged above the base, the tension adjustment mechanism is located on one side of the stranding drive mechanism, and the rotating disk is located on the other side of the stranding drive mechanism. The tension adjustment mechanism includes an upper auxiliary roller, a lower auxiliary roller, a tension adjustment roller, a slide rod and a bracket. Through the stranding drive mechanism, multiple single conductors can be gradually twisted together, and the upper auxiliary roller, the lower auxiliary roller and the tension adjustment roller arranged in the tension adjustment mechanism are used in coordination. When the tension adjustment roller moves upward, it can gradually support the wire body passing above the tension adjustment roller, thereby increasing the tension, and when the tension adjustment roller moves downward, the wire body supported by the wire body is gradually relaxed, so that its tension becomes smaller.

[0004] During use, the above structure adjusts the tension of the conductor body through the tension adjustment mechanism, but it only adjusts the tension of the twisted conductors, but cannot control the tightness of each cable during the twisting process, which may make the cable too loose and not tight enough after twisting.

[0009] As a further solution of the present invention: one side of each adjusting slider is rotatably connected to one end of the connecting rod, and the other end of the connecting rod is rotatably matched with the measuring slider. The measuring slider is linearly slidably installed in the corresponding fixed slide, and the fixed slide is fixedly installed on the second tensioning disk. A tension sensor is arranged on the inner wall of the fixed slide, and one end of the measuring slider is connected to the tension sensor through a tension spring.

[0010] As a further solution of the present invention: a sliding rod is slidably provided on the measuring slider, a cable pull ring is provided on the top of the sliding rod, the cable passes through the cable pull ring after passing around the tensioning wheel, a baffle is fixedly provided at the bottom end of the sliding rod, and a return spring is provided between the baffle and the measuring slider.

[0011] As a further solution of the present invention: a swing frame is provided on one side of the first tensioning disk corresponding to the first threading hole, and a leaning cavity is provided inside the swing frame. The swing frame leans parallel to the tensioned cable through the leaning cavity. A rotating shaft is provided at the top of the swing frame, and the rotating shaft is rotatably installed on the rotating seat through a torsion spring. Top blocks are provided on both sides of the bottom end of the swing frame.

[0012] As a further solution of the present invention: a matching seat is arranged on the outer wall of the boss circumference corresponding to the swing frame, a clamping part is arranged on one side of the matching seat, the clamping part is engaged with the leaning cavity, a groove part is arranged below the clamping part, the groove part is engaged with the top block, and an alarm switch is arranged on the groove part.

The cable is wound on the winding roller, and the cable passes through the first threading hole, the tensioning wheel, the second threading hole, the wire hole and the wire bundle groove in sequence.

[0014] Beneficial effects of the present invention:

[0015] (1) By setting up a tensioning assembly, each cable will pass through the tensioning wheel from the first threading hole and then continue to pass through the second threading hole during the transportation process. When the tension of the cable needs to be adjusted, the adjustment motor drives the adjustment plate to rotate. During the rotation of the adjustment plate, the sliding cooperation between the sliding pin and the inclined slide groove will drive multiple groups of adjustment sliders to slide radially synchronously, so as to adjust the extension spacing of the tensioning wheel. When the spacing becomes smaller, the cable becomes tighter and its tension increases. When the spacing becomes larger, the cable becomes looser and its tension decreases. Then, the tension control and adjustment of the cable transportation process is realized by changing the spacing of the tensioning wheel, which is beneficial to improve the tightness of the cable when it is twisted.

[0016] (2) By setting a measuring slider, during the cable tension control and adjustment process, the adjusting slider will drive the tensioning wheel to slide radially, and at the same time, the adjusting slider will drive the measuring slider to move linearly synchronously through the connecting rod. During the movement, the measuring slider will pull the tension spring to deform it, and use the tension sensor to monitor the tension change in real time. When the tension exceeds the threshold set in advance, it means that the cable has been straightened and tightened to the limit. Therefore, the tension of the cable can be intuitively fed back based on the monitoring value of the tension, avoiding the cable from breaking due to excessive tension.

[0017] (3) By setting up a swing frame and a matching seat, during the tensioning and conveying process of each cable, the swing frame will be parallel to the cable and swing synchronously with the cable. At this time, the swing frame will be subjected to the elastic force of the torsion spring and will apply pressure to the cable through the overlapping cavity to limit the position to ensure that it is conveyed in the correct direction. When the cable breaks, the cable will no longer provide support for the swing frame. The swing frame will instantly swing back to its original position under the action of the torsion spring. At this time, the clamping part will cooperate with the overlapping cavity to clamp one end of the cable, thereby avoiding the interlacing and disorder of the cable ends when the cable breaks. At the same time, the top block will also be engaged in the groove and trigger the alarm switch. The alarm switch will simultaneously respond to the alarm and the alarm light, thereby reminding the staff to locate which cable is broken, which is conducive to timely error correction.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1 and Figure 2 As shown, the present invention is a cable tension control stranding device, comprising a base 1, a stranding motor 2 is fixedly arranged on the upper end of the base 1, a rotating frame 11 is fixedly arranged on both sides of the upper end of the base 1, the output end of the stranding motor 2 is connected to the stranding shaft 3 through a transmission belt 21, the stranding shaft 3 is rotatably installed in the rotating frame 11, one end of the stranding shaft 3 is fixedly connected to a winding drum 4, the winding drum 4 is fixedly connected to the first tensioning drum 5 through a circumferentially uniformly distributed winding shaft 41, each winding shaft 41 is rotatably installed with a winding roller 42, the first tensioning drum 5 is fixedly connected to the second tensioning drum 7 through a boss 52, the first tensioning drum 5 and the second tensioning drum 7 are respectively and circumferentially uniformly provided with a first threading hole 51 and a second threading hole 71, and a tensioning assembly 6 is arranged in the boss 52.

[0032] Specifically, by setting the first tensioning disk 5 and the second tensioning disk 7, each cable is respectively wound on the winding roller 42, and passes through the first threading hole 51 and the second threading hole 71 in sequence. In this process, the tensioning component 6 is used to synchronously control and adjust the tension of multiple cables, so that each cable is tightened and straightened. At the same time, the stranding motor 2 is used to drive the stranding shaft 3, the first tensioning disk 5 and the second tensioning disk 7 to rotate, so as to ensure that the stranding is tight.

[0033] like Figure 3 , Figure 4 , Figure 8 and Fig. 9 As shown, the tensioning assembly 6 includes an adjusting plate 61, an adjusting motor 62 and an adjusting slider 63. The surface of the boss 52 is uniformly provided with radial sliding grooves 521 in the circumferential direction. The adjusting slider 63 is slidably installed in the sliding groove 521. A rotating groove 522 is provided inside the boss 52. The adjusting plate 61 is rotatably installed in the rotating groove 522. The adjusting motor 62 is fixedly installed inside the boss 52, and the output end of the adjusting motor 62 is fixedly connected to the center of the adjusting plate 61. The adjusting plate 61 is uniformly penetrated with oblique sliding grooves 611. A sliding pin 641 is fixedly provided on one side of each adjusting slider 63. The sliding pin 641 is adapted to be slidably installed in the corresponding oblique sliding groove 611. The tail end of the adjusting slider 63 is connected to the sliding groove 521 through a return spring 632. A bracket 633 is extended from the top of the adjusting slider 63. A tensioning wheel 634 is rotatably installed in the bracket 633. Each cable passes through the tensioning wheel 634 from the first threading hole 51 and then continues to pass through the second threading hole 71.

[0034] Specifically, by setting up the tensioning assembly 6, each cable will pass through the first threading hole 51, around the tensioning wheel 634, and then continue to pass through the second threading hole 71 during the transportation process. When the tension of the cable needs to be adjusted, the adjustment motor 62 drives the adjustment plate 61 to rotate. During the rotation of the adjustment plate 61, the sliding cooperation between the sliding pin 641 and the inclined slide groove 611 will drive multiple groups of adjustment sliders 63 to slide radially synchronously, so as to adjust the extension spacing of the tensioning wheel 634. When the spacing becomes smaller, the cable becomes more and more taut, and its tension increases. When the spacing becomes larger, the cable becomes looser and its tension decreases. Then, the tension control and adjustment of the cable transportation process is realized by changing the spacing of the tensioning wheel 634, which is beneficial to improve the tightness of the cable when it is twisted.

[0035] like Fig. 9 and Fig.10 As shown, one side of each adjusting slider 63 is rotationally connected to one end of the connecting rod 64, and the other end of the connecting rod 64 is rotationally matched with the measuring slider 66. The measuring slider 66 is linearly slidably installed in the corresponding fixed slide 65, and the fixed slide 65 is fixedly installed on the second tensioning disk 7. A tension sensor 67 is arranged on the inner wall of the fixed slide 65, and one end of the measuring slider 66 is connected to the tension sensor 67 through a tension spring 661.

[0036] Specifically, by setting a measuring slider 66, during the cable tension control and adjustment process, the adjusting slider 63 will drive the tensioning wheel 634 to slide radially, and at the same time, the adjusting slider 63 will drive the measuring slider 66 to move synchronously in a straight line through the connecting rod 64. During the movement, the measuring slider 66 will pull the tension spring 661 to deform it, and use the tension sensor 67 to monitor the tension change in real time. When the tension exceeds the threshold set in advance, it means that the cable has been straightened and tightened to the limit. Therefore, the tension of the cable can be intuitively fed back based on the monitoring value of the tension, so as to avoid the cable breaking due to excessive tension.

[0037] like Fig.10 As shown, a slide rod 68 is slidably provided on the measuring slider 66, a cable tie ring 681 is provided at the top of the slide rod 68, and the cable passes through the cable tie ring 681 after passing around the tensioning wheel 634. A baffle plate 682 is fixedly provided at the bottom of the slide rod 68, and a return spring 683 is provided between the baffle plate 682 and the measuring slider 66.

[0038] Specifically, by setting the slide bar 68, when the tension is measured, the slide bar 68 will slide linearly on the cable along with the measuring slider 66. At the same time, during this process, the slide bar 68 is acted upon by the elastic force of the return spring 683 and will always maintain a tendency to slide downward, so that the cable pull ring 681 will always rest on the tensioned cable and exert a downward tension on the cable, thereby limiting the position of the cable and straightening it to prevent the tensioned cable from jumping.

[0039] like Figure 5 As shown, a swing frame 53 is provided on one side of the first tensioning disk 5 in one-to-one correspondence with the first threading hole 51, and a leaning cavity 531 is provided inside the swing frame 53. The swing frame 53 leans parallel to the tensioned cable through the leaning cavity 531. A rotating shaft 532 is provided at the top of the swing frame 53. The rotating shaft 532 is rotatably installed on the rotating seat through a torsion spring 533, and top blocks 534 are provided on both sides of the bottom end of the swing frame 53.

[0040] Further, such as Figure 6 and Figure 7 As shown, a matching seat 54 is provided on the circumferential outer wall of the boss 52 corresponding to the swing frame 53, a clamping portion 541 is provided on one side of the matching seat 54, the clamping portion 541 is engaged with the supporting cavity 531, a groove portion 542 is provided below the clamping portion 541, the groove portion 542 is engaged with the top block 534, and an alarm switch 543 is provided on the groove portion 542.

[0041] Specifically, by providing the swing frame 53 and the matching seat 54, during the tensioning and conveying process of each cable, the swing frame 53 will be parallel to the cable and swing synchronously with the cable. At this time, the swing frame 53 is subjected to the elastic force of the torsion spring 533, and will apply pressure and limit the cable through the leaning cavity 531 to ensure that it is conveyed in the correct direction. When the cable breaks, the cable will no longer provide support for the swing frame 53. The swing frame 53 will instantly swing back to its original position under the action of the torsion spring 533. At this time, the clamping portion 541 will cooperate with the leaning cavity 531 to clamp one end of the cable, thereby avoiding the interlacing and disorder of the cable ends when the cable breaks. At the same time, the top block 534 will also be engaged in the groove portion 542 and trigger the alarm switch 543. The alarm switch 543 will simultaneously respond to the alarm and the alarm light, thereby reminding the staff to locate which cable is broken, which is conducive to timely error correction.

[0042] like Figure 3 As shown, the second tensioning disk 7 is fixedly connected to the capstan drum 8, and the capstan drum 8 is rotatably installed in the rotating frame 11. The capstan drum 8 is evenly provided with capstan holes 81 circumferentially, and the extension column at one end of the capstan drum 8 is evenly provided with a cable slit 82 circumferentially. The cable is wound on the winding roller 42, and the cable passes through the first threading hole 51, the tensioning wheel 634, the second threading hole 71, the capstan hole 81 and the cable slit 82 in sequence.

[0043] The working principle of the present invention is as follows: Figure 1-Figure 10As shown, when in use, each strand of cable is wound around the corresponding winding roller 42, and the cable passes through the first threading hole 51, the tensioning wheel 634, the second threading hole 71, the twisting hole 81 and the cable bundle groove 82 in sequence. When the tension of the cable needs to be adjusted, the adjusting motor 62 drives the adjusting plate 61 to rotate. During the rotation of the adjusting plate 61, the sliding cooperation between the sliding pin 641 and the inclined slide groove 611 is utilized to drive multiple groups of adjusting sliders 63 to slide radially synchronously, so as to adjust the extension spacing of the tensioning wheel 634. When the spacing becomes smaller, the cable becomes tighter and its tension increases. When the spacing becomes larger, the cable becomes looser and its tension decreases. Then, the tension control and adjustment of the cable conveying process is realized by changing the spacing of the tensioning wheel 634, which is beneficial to improve the tightness of the cable twisting. During the cable tension control and adjustment process, the adjustment slider 63 will drive the tensioning wheel 634 to slide radially, and at the same time, the adjustment slider 63 will drive the measuring slider 66 to move synchronously in a straight line through the connecting rod 64. During the movement, the measuring slider 66 will pull the tension spring 661 to deform it, and use the tension sensor 67 to monitor the tension change in real time. When the tension exceeds the threshold set in advance, it means that the cable has been straightened and tightened to the limit. Therefore, the tension of the cable can be intuitively fed back based on the monitoring value of the tension, so as to avoid the cable breaking due to excessive tension. When the cable breaks, the cable will no longer provide support for the swing frame 53. The swing frame 53 will instantly swing back to its original position under the force of the torsion spring 533. At this time, the clamping portion 541 will cooperate with the cavity 531 to clamp one end of the cable, thereby avoiding the disorder of the cable ends when the cable breaks. At the same time, the top block 534 will also be engaged in the groove portion 542 and trigger the alarm switch 543. The alarm switch 543 will respond to the alarm and the alarm light at the same time, thereby reminding the staff to locate which cable is broken, which is conducive to timely error correction.

[0044] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention.
