Description

Technical Field

[0001] This utility model relates to the field of tensioners, and in particular to a pneumatic anti-tension dual-servo induction tensioner. Background Technology

[0002] Before winding the coil onto the coil bobbin, the front end of the wire needs to be wound around the bobbin's pins. Since the wire tension required for winding the pins is very small, a slack section of wire needs to be pulled out before winding the pins. Traditional semi-automatic winding equipment requires manual pulling of a slack section of wire to work with the winding guide pin to complete the winding. After the winding guide pin finishes winding the pins, the slack wire needs to be manually pulled back to tension it, and the tensioned wire needs to be wound back. Only after completing all these steps can the coil be wound onto the bobbin, resulting in low winding efficiency and high cost. To address these issues, the industry urgently needs to develop a wire tensioning device that can drive a counter-tension rod to swing downwards to release the wire, preventing wire breakage due to excessive tension during pin winding. This device should also be able to quickly drive the counter-tension rod upwards to tension the wire after the front end of the wire is secured during pin winding, preparing for the next step of coil winding.

[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows: 1. By installing a tension adjustment mechanism inside the housing for controlling the tension of the first anti-tension component, and designing the structure of the tension adjustment mechanism, the rack drive device in the tension component of the tension adjustment mechanism drives the rack to move linearly, which in turn drives the gear to rotate. The gear drives the first rotating shaft to rotate, and the first rotating shaft drives the anti-tension rod to swing downward to release the wire. The tension of the released wire meets the requirements for winding the needle, avoiding the wire from breaking due to excessive tension during the winding process. After the needle is wound, the first rotating shaft drives the anti-tension rod to swing upward to tension the wire. This achieves fully automatic and rapid release and tension of the wire, improves the efficiency of winding the coil, and reduces the cost of winding the coil.

[0014] 2. By installing an adjusting component on the adjusting mounting frame for controlling the tensioning of the tensioning assembly wire, and designing the structure of the adjusting component, when the first adjusting screw in the adjusting component is turned, the first adjusting screw drives the first limiting block to slide on the second adjusting screw. When the second adjusting screw in the adjusting component is turned, the second adjusting screw drives the second limiting block to slide on the first adjusting screw. The first limiting block and the second limiting block limit the movable block, thereby limiting the linear motion of the rack. Ultimately, precise control of the released wire and the tensioning wire is achieved to meet the needs of different wire release lengths, avoiding excessive wire release which would reduce the efficiency of tensioning the wire after release, thus improving the efficiency of tensioning the wire.

[0015] 3. It features a first anti-tension assembly for adjusting wire tension installed on one side of the housing, and a second anti-tension assembly for assisting the first anti-tension assembly in adjusting wire tension, both installed on the same side of the housing. The structures of the first and second anti-tension assemblies are designed separately. When the wire tension is too high, the hanging wheel on the anti-tension rod is pulled by the wire, causing the anti-tension rod to swing downward. The anti-tension rod of the first anti-tension assembly acts on the hanging rod through the first spring, causing the hanging rod to swing downward and thus the stop lever to swing downward. The stop lever drives the bushing to rotate through the mounting part, which in turn drives the hook part to rotate in a direction away from the fixed plate. The pulling force provided by the second spring on the hook part indirectly acts on the anti-tension rod, enhancing the pulling force of the first spring on the anti-tension rod. This prevents the anti-tension rod from swinging too much when the wire tension is too high, thus ensuring the stability of the wire conveying. Attached Figure Description

[0029] Reference Figure 3As shown, the tension adjustment mechanism 5 includes an adjustment mounting frame 51, a tensioning component 52, and an adjustment component 53. The adjustment mounting frame 51 is installed inside the housing 2. The tensioning component 52 is installed on the adjustment mounting frame 51 and is used to drive the first anti-tension component 41 to tension the wire after the wire head is fixed. The adjustment component 53 is installed on the adjustment mounting frame 51 and is used to control the tensioning component 52 to tension the wire.

[0030] Reference Figure 2 , Figures 3 to 7 As shown, the tensioning assembly 52 includes a first bearing seat 520, a first bearing 521, a first rotating shaft 522, a gear 523, a first spacer 524, a second spacer 525, a slide 526, a rack 527, and a rack drive device 528. The first bearing seat 520 is mounted on one side wall of the adjusting mounting bracket 51. The first bearing 521 is installed inside the first bearing seat 520. The first rotating shaft 522 passes through the first bearing 521. The first spacer 524 and the second spacer 525 are respectively sleeved on the first rotating shaft 522. Located on both sides of the first bearing 521, the gear 523 is sleeved on one end of the first rotating shaft 522 and is located inside the adjusting mounting bracket 51. The first partition plate 524 is located between the gear 523 and the first bearing 521. The slide 526 is installed on one inner side wall of the adjusting mounting bracket 51 and is located below the gear 523. The rack drive device 528 is installed on one end of the adjusting mounting bracket 51. The rack 527 is installed on the output end of the rack drive device 528 and is laterally slidably installed on the slide 526. The rack 527 and the gear 523 are meshed and connected.

[0031] By adopting the above technical solution, the rack drive device 528 drives the rack 527 to make linear motion, thereby driving the gear 523 to rotate. The gear 523 drives the first rotating shaft 522 to rotate. The rack 527 is laterally slidably mounted on the slide block 526. The slide block 526 supports the sliding of the rack 527, ensuring the smoothness and stability of the meshing transmission between the rack 527 and the gear 523. The first partition plate 524 is located between the gear 523 and the first bearing 521, preventing the first rotating shaft 522 from shifting laterally in the axial direction within the first bearing 521, thus ensuring the smoothness of the rotation of the first rotating shaft 522 within the first bearing 521.

[0032] In this embodiment, the rack and pinion drive device 528 is preferably a cylinder.

[0033] Reference Figure 3As shown, the adjustment assembly 53 includes a movable block 530, a first adjusting screw 531, a second adjusting screw 532, a first limiting block 533, a second limiting block 534, a first pointer 535, and a second pointer 536. The first adjusting screw 531 and the second adjusting screw 532 are rotatably mounted on the two ends of the adjustment mounting bracket 51 from top to bottom. A first fixing screw 537 and a second fixing screw 538 are threadedly connected from top to bottom to the other end of the adjustment mounting bracket 51. The first fixing screw 537 is perpendicular to the first adjusting screw 531 and is used to fix the first adjusting screw 531 on the adjustment mounting bracket 51. The second fixing screw 538 is perpendicular to the second adjusting screw 532 and is used to fix the second adjusting screw 532 on the adjustment mounting bracket 51. The upper end of the first limiting block 533 is threadedly connected to the first adjusting screw 531, and the lower end of the first limiting block 533 slides... The movable block 530 is slidably sleeved on the second adjusting screw 532, and the upper end of the second limiting block 534 is slidably sleeved on the first adjusting screw 531. The lower end of the second limiting block 534 is threadedly connected to the second adjusting screw 532. The first limiting block 533 and the second limiting block 534 are respectively located on the inner sides of both ends of the adjusting mounting bracket 51. The upper and lower ends of the movable block 530 are slidably sleeved on the first adjusting screw 531 and the second adjusting screw 532, and the movable block 530 is located between the first limiting block 533 and the second limiting block 534. The movable block 530 is connected and installed to the rack 527 and moves linearly with the rack 527. The first limiting block 533 and the second limiting block 534 limit the movable block 530. The first pointer 535 is installed on the first limiting block 533 and is used to indicate the maximum stroke for releasing tension. The second pointer 536 is installed on the second limiting block 534 and is used to indicate the maximum stroke for tensioning the wire.

[0034] By adopting the above technical solution, twisting the first adjusting screw 531 causes the first limiting block 533 to slide on the second adjusting screw 532. Twisting the second adjusting screw 532 causes the second limiting block 534 to slide on the first adjusting screw 531. The first limiting block 533 and the second limiting block 534 limit the movable block 530, thereby limiting the linear motion of the rack 527, and finally achieving precise control over the release and tension of the wire.

[0035] Reference Figure 2 and Figure 8As shown, the first anti-tension assembly 41 includes a hanging rod 411, a second bearing seat 412, a second bearing 413, a second rotating shaft 414, an anti-tension rod 415, a buckle 416, a hanging wheel 417, and a first spring 418. One end of the hanging rod 411 is fixedly connected to the other end of the first rotating shaft 522, and the hanging rod 411 and the first rotating shaft 522 are perpendicular to each other. The second bearing seat 412 is installed on one side wall of the housing 2, and the second bearing 413 is installed on the second shaft 522. Inside the bearing 412, the second rotating shaft 414 passes through the second bearing 413. The lower end of the anti-tension rod 415 is fixedly connected to the second rotating shaft 414, and the anti-tension rod 415 and the second rotating shaft 414 are perpendicular to each other. The buckle 416 is fixedly installed on the middle part of the anti-tension rod 415. The two ends of the first spring 418 are respectively connected and installed to the buckle 416 and the other end of the hanging rod 411. The wire hanging wheel 417 is rotatably installed on the upper end of the anti-tension rod 415 and is used to hang the wire.

[0036] By adopting the above technical solution, the two ends of the first spring 418 are respectively connected and installed to the buckle 416 and the other end of the hanging rod 411. The wire is hung on the hanging wheel 417. The anti-tension rod 415 tensions the wire through the hanging wheel 417. The tension of the wire by the anti-tension rod 415 is interfered with by the tension of the first spring 418. When the tension of the wire changes within a predetermined range, the angle between the anti-tension rod 415 and the vertical direction changes within a predetermined range.

[0037] Reference Figures 4 to 8 As shown, the second anti-tension assembly 42 includes a bushing 421, a third bearing 422, a stop bar 423, a second spring 424, and a fixing plate 425. The third bearing 422 is sleeved on the other end of the first rotating shaft 522, and the bushing 421 is sleeved on the third bearing 422. The bushing 421 has a mounting part 426 and a hook part 427 on its two sides respectively. The stop bar 423 is mounted on the mounting part 426 and is used to actuate the hook bar 411. The fixing plate 425 is mounted on one side of the housing 2. The two ends of the second spring 424 are connected and installed to the hook part 427 and the fixing plate 425 respectively.

[0038] By adopting the above technical solution, the bushing 421 can rotate on the first rotating shaft 522 via the third bearing 422. The hook part 427, under the tension of the second spring 424, swings towards the fixing plate 425. The hook part 427 drives the bushing 421 to rotate, which in turn drives the mounting part 426 to rotate upwards. The mounting part 426 drives the stop rod 423 to swing upwards, which in turn moves the hanging rod 411 to swing upwards. When the tension of the wire is too high, the hanging wheel 417 on the anti-tension rod 415 is pulled by the wire, and the anti-tension rod 41... 5. When the wire tension is too high, the anti-tension rod 415 acts on the hanging rod 411 through the first spring 418. The hanging rod 411 swings downward, which in turn causes the stop rod 423 to swing downward. The stop rod 423 drives the bushing 421 to rotate through the mounting part 426, which in turn drives the hook part 427 to rotate in a direction away from the fixing piece 425. The pulling force provided by the second spring 424 to the hook part 427 indirectly acts on the anti-tension rod 415, which enhances the pulling force of the first spring 418 on the anti-tension rod 415 and avoids the anti-tension rod 415 from swinging too much when the wire tension is too high.

[0039] Reference Figure 2 and Figure 9 As shown, the first wire feeding assembly 31 includes a first motor 311 mounted on the inner side of the panel 1. A first wire feeding wheel 312 is fixedly mounted on the output shaft of the first motor 311. The first wire feeding wheel 312 is located on the front side of the panel 1. The first motor 311 drives the first wire feeding wheel 312 to rotate for wire feeding.

[0040] Reference Figure 2 and Figure 9 As shown, the second wire feeding assembly 32 includes a second motor 321 mounted on the inner side of the panel 1. A second wire feeding wheel 322 is fixedly mounted on the output shaft of the second motor 321. The second wire feeding wheel 322 is located on the front side of the panel 1. The second motor 321 drives the second wire feeding wheel 322 to rotate for wire feeding. The first wire feeding wheel 312 is located above the second wire feeding wheel 322. The first wire feeding wheel 312 and the second wire feeding wheel 322 feed wires sequentially.

[0041] Reference Figure 2 and Figure 9 As shown, a wool felt clip 11 is installed on the panel 1. The wool felt clip 11 is located on one side of the second wire feeding wheel 322 and is used to clean the wire. A limiting plate 12 is provided below the wool felt clip 11. The limiting plate 12 is fixedly installed on the panel 1 and is used to position the wire. A first guide wheel 13 and a second guide wheel 14 are respectively provided on the upper and lower sides of the pressure sensor 6. The first guide wheel 13 and the second guide wheel 14 are respectively rotatably installed on the panel 1 and are used to convey the wire.

[0042] By adopting the above technical solution, after the wire passes through the limiting plate 12, it sequentially passes around the first wire feeding wheel 312, the second wire feeding wheel 322, the first guide wheel 13, and the second guide wheel 14. The first motor 311 and the second motor 321 drive the first wire feeding wheel 312 and the second wire feeding wheel 322 to rotate and feed the wire. The wool felt clamp 11 clamps the wire to clean it. The first guide wheel 13 and the second guide wheel 14 limit and transmit the wire and fix it on the pressure sensor 6 to ensure that the pressure sensor 6 is in full contact with the wire. The pressure sensor 6 detects the tension of the wire. The first motor 311 and the second motor 321 adjust the wire feeding speed according to the tension of the wire detected by the pressure sensor 6 to ensure that the anti-tension rod 415 swings within a predetermined angle range, the smoothness of wire transmission, and the constant tension of the wire.

[0043] Its overall structural design enables fully automatic and rapid wire release and tensioning, as well as precise control over both the released and tensioned wires. This meets the needs of releasing wires of different lengths, avoiding excessive wire release that could affect the efficiency of tensioning the wire after release. This improves the efficiency of wire tensioning and eliminates the need for manual intervention in wire release, tensioning, and winding, reducing labor intensity and costs for businesses. It effectively solves the problems of traditional semi-automatic winding equipment, which requires manual wire pulling before winding the bobbin needles, manual tensioning after winding, and manual winding of the tensioned wire. These problems result in low coil winding efficiency, high coil winding costs, high labor intensity for workers, and high labor costs for businesses.
