Description

Technical Field

[0001] This utility model relates to the field of tensioners, and in particular to a mechanical adjustable tension self-balancing wire tensioner. Background Technology

[0002] As the wire reel is continuously unwound and fed, the wire coil gradually becomes smaller or even empty, often resulting in inconsistent tension during the winding and feeding process. Simultaneously, as the wire is wound around the bobbin, the coils on the bobbin gradually increase in size, again causing inconsistencies between the winding tension and the feeding tension. Currently, most tensioners on the market control wire tension by using a motor to feed the wire. However, controlling the wire tension through a motor and its speed requires pressure sensors and control chips, significantly increasing costs and hindering industrial development. Furthermore, controlling the motor speed via pressure sensors and chips introduces a delay, greatly reducing the accuracy and efficiency of wire tension control. Summary of the Invention

The drawings illustrate preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0040] Reference Figures 1-2 As shown, this utility model discloses a mechanical adjustable tension self-balancing wire tensioner, comprising a tension plate 1, a damping braking mechanism 2 installed on one side of the tension plate 1 for conveying wire and adjusting wire tension; a cleaning component 3 installed on one side of the tension plate 1 and located on one side of the damping braking mechanism 2 for cleaning the wire; an inlet limit frame 4 installed at the bottom of the tension plate 1 and located below the cleaning component 3 for limiting the wire before it passes through the cleaning component 3; a delivery limit frame 5 installed on one side of the tension plate 1 and located on the other side of the damping braking mechanism 2 for limiting the wire to prevent it from detaching from the damping braking mechanism 2; and a delivery guide wheel 6 installed on one side of the tension plate 1 and located above the cleaning component 3 for conveying the wire. The guide wheel 7, mounted on one side of the tension plate 1 and above the damping braking mechanism 2, is used to guide and limit the wire being conveyed; the anti-tension adjustment assembly 8, mounted on the top of the tension plate 1, is used to tension the wire; the damping adjustment assembly 9, mounted on the other side of the tension plate 1 and connected to the anti-tension adjustment assembly 8, is used to adjust the damping of the damping braking mechanism 2; the wire threading knob assembly 10, mounted on the other side of the tension plate 1, is used to stop or start the damping adjustment assembly 9 to adjust the damping of the damping braking mechanism 2; the scale groove 11, located at the lower end of the tension plate 1 and corresponding to the damping adjustment assembly 9, is used to display the tension adjustment data; and the mounting sleeve 12, mounted at the lower end of the tension plate 1, is used to fix the tension plate 1 in place.

[0041] Reference Figure 3 As shown, the damping braking mechanism 2 includes a tension adjusting guide wheel assembly 21, a damping braking assembly 22, and a brake shaft assembly 23. The damping braking assembly 22 is mounted on the tension plate 1. The tension adjusting guide wheel assembly 21 is mounted on the side of the damping braking assembly 22 away from the tension plate 1 and is used to transport the wire and adjust the tension of the wire. The brake shaft assembly 23 is transversely mounted through the damping braking assembly 22 and the tension adjusting guide wheel assembly 21 and is used to pull the tension adjusting guide wheel assembly 21 to press it against the damping braking assembly 22.

[0042] In this embodiment, refer to Figure 3 and Figure 4 As shown, the brake shaft assembly 23 pulls the tension adjusting guide wheel assembly 21 to press it against the damping brake assembly 22. The wire is wound on the tension adjusting guide wheel assembly 21 and can drive the tension adjusting guide wheel assembly 21 to rotate when the wire is being transported. The damping brake assembly 22 generates damping on the tension adjusting guide wheel assembly 21 to control the tension of the wire being transported.

[0043] Reference Figures 5-7As shown, the tension adjusting guide wheel assembly 21 includes a tension adjusting rotating wheel 210, a first O-ring 211, a second O-ring 212, and an O-ring mounting ring 213 arranged in sequence. The tension adjusting rotating wheel 210 has a first O-ring mounting groove 214 for fixing the first O-ring 211 on one side facing the first O-ring 211, and a friction plate receiving groove 215 on the other side of the tension adjusting rotating wheel 210.

The O-ring mounting ring 213 has a second O-ring mounting groove 217 for fixing the second O-ring 212 on one side facing the second O-ring 212.

[0044] In this embodiment, the O-ring mounting ring 213 fixes the first O-ring 211 and the second O-ring 212 to the side of the tension adjusting rotating wheel 210 by screws.

[0045] Reference Figure 7 and Figure 8 As shown, the damping braking assembly 22 includes a brake mounting base 221, a friction pad mounting base 222, and a friction pad 223. The brake mounting base 221 is mounted on the tension plate 1. The friction pad mounting base 222 is mounted on the side of the brake mounting base 221 facing away from the tension plate 1. The friction pad 223 is mounted on the side of the friction pad mounting base 222 facing away from the tension plate 1 and generates frictional damping on the tension adjusting rotating wheel 210. The friction pad 223 has a friction pad center hole 224 at its center. The other side of the friction pad mounting base 222... The friction pad mounting base 222 has a brake lever groove 225, two pin grooves 226 and two pin holes 227. The brake lever groove 225 is vertically arranged on the friction pad mounting base 222. The two pin grooves 226 are horizontally arranged on the friction pad mounting base 222 and are located on both sides of the brake lever groove 225. The two pin holes 227 are vertically arranged on the friction pad mounting base 222 and are located in the two pin grooves 226. The center of the friction pad mounting base 222 has a brake shaft hole 228, which vertically passes through the brake lever groove 225.

[0046] In this embodiment, since the friction plate 223, which acts as a damper, is installed on the friction plate mounting base 222, the tension adjusting rotating wheel 210 presses the friction plate 223, and the friction plate 223 generates friction on the tension adjusting rotating wheel 210 to generate damping on the tension adjusting guide wheel assembly 21, thereby generating resistance to wire transmission and increasing the tension of the wire.

[0047] Reference Figures 5-9As shown, the brake shaft assembly 23 includes a brake shaft 230, two bearings 231, bearing baffles 232, a brake lever 233, a shaft pin 234, two pins 235, a brake shaft nut 236, and a counter-tension adjusting screw 237. The brake shaft 230 transversely passes through the tension plate 1, the center hole 216 of the rotating wheel, and the brake shaft hole 228. The two bearings 231 are arranged side by side, and the bearing baffles 232 are located between the two bearings 231. The two bearings 231 and the bearing baffles 232 are mounted on one end of the brake shaft 230 and at the center of the rotating wheel. Inside the hole 216, the brake lever 233 is L-shaped. One end of the brake lever 233 is mounted on the other end of the brake shaft 230 via the brake shaft nut 236. The shaft pin 234 passes vertically through the middle of the brake lever 233 and protrudes from both sides of the brake lever 233. The shaft pin 234 is installed in two shaft pin grooves 226. The anti-tension adjusting screw 237 is installed on the other end of the brake lever 233 via the adjusting screw nut 238. Two pins 235 are respectively installed in the pin holes 227 and are located on the outer sides of the two ends of the shaft pin 234.

[0048] In this embodiment, when the anti-tension adjusting screw 237 of the brake shaft assembly 23 is pressed downward, the brake lever 233 moves around the shaft pin 234, and the brake lever 233 pulls the brake shaft 230 upward. The brake shaft 230 pulls the tension adjusting guide wheel assembly 21 to press against the damping brake assembly 22 through the bearing 231. The wire is wound on the tension adjusting guide wheel assembly 21 and can drive the tension adjusting guide wheel assembly 21 to rotate when the wire is conveyed. The damping brake assembly 22 generates damping on the tension adjusting guide wheel assembly 21. The greater the pulling force of the brake shaft assembly 23 on the tension adjusting guide wheel assembly 21, the greater the damping of the damping brake assembly 22 on the tension adjusting guide wheel assembly 21, the slower the speed of the wire conveyed on the tension adjusting guide wheel assembly 21, and the greater the tension of the wire.

[0049] Reference Figure 10As shown, the anti-tension adjustment assembly 8 includes an anti-tension guide wheel 80, an anti-tension guide wheel mounting block 81, an anti-tension rod 82, an anti-tension rotating shaft 83, an anti-tension fixing ring 84, an anti-tension rotating bushing 85, an anti-tension adjustment rod fixing block 86, an anti-tension adjustment fixing block 87, an anti-tension rotating shaft nut 88, an anti-tension adjustment rod 89, an elastic element fixing block 801, an anti-tension adjustment fixing screw 802, an anti-tension adjustment elastic element 803, and an anti-tension stop bar 804; the anti-tension rotating shaft 83 is vertically mounted on the tension plate 1 via the anti-tension rotating bushing 85; the anti-tension adjustment fixing block 87 is located on one side of the tension plate 1, one end of the anti-tension adjustment fixing block 87 is fixedly mounted to one end of the anti-tension rotating shaft 83 via the anti-tension rotating shaft nut 88, and the other end of the anti-tension adjustment fixing block 87 is mounted on the tension plate 1; the anti-tension rod 82 is located on the tension plate 1. On one side, the anti-tension rod 82 is vertically mounted on one end of the anti-tension rotating shaft 83 via the anti-tension fixing ring 84. The anti-tension guide wheel mounting block 81 is mounted on the other end of the anti-tension rod 82, and the anti-tension guide wheel 80 is mounted on the anti-tension guide wheel mounting block 81. The anti-tension adjusting rod 89 is located on the other side of the tension plate 1, and one end of the anti-tension adjusting rod 89 is mounted on the anti-tension rotating shaft 83 via the anti-tension adjusting rod fixing block 86. The upper end of the anti-tension adjusting elastic element 803 is mounted on the anti-tension adjusting rod 89. The elastic element fixing block 801 is mounted on the anti-tension adjusting rod 89 via the anti-tension adjusting fixing screw 802 and fixes and limits the upper end of the anti-tension adjusting elastic element 803. The anti-tension stop rod 804 is mounted on the tension plate 1 and located on one side of the anti-tension rotating shaft 83. The anti-tension stop rod 804 limits the rotation of the anti-tension adjusting rod fixing block 86.

[0050] In this embodiment, the wire is hung on the anti-tension guide wheel 80. When the tension of the wire increases, it pulls the anti-tension rod 82 to swing downward, which in turn drives the anti-tension shaft 83 to rotate. The rotating anti-tension shaft 83 drives the anti-tension adjusting rod 89 to swing upward, so that the anti-tension adjusting rod 89 pulls the anti-tension adjusting elastic element 803 upward.

[0051] Reference Figure 10As shown, the damping adjustment assembly 9 includes a tension adjustment swing rod 90, a tension adjustment rod fixing seat 91, a tension adjustment elastic element 92, a tension adjustment pull rod 93, a tension adjustment indicator rod 94, a tension adjustment base plate 95, and a tension adjustment knob 96. One end of the tension adjustment swing rod 90 is connected to the lower end of the anti-tension adjustment elastic element 803, and the other end of the tension adjustment swing rod 90 is oscillatingly mounted on the side of the tension plate 1 through the tension adjustment rod fixing seat 91, with the tension adjustment swing rod 90 located above the anti-tension adjustment screw 237. The tension adjustment elastic element 92 is located below one end of the tension adjustment swing rod 90. The upper end of the tension adjusting elastic element 92 is connected to one end of the tension adjusting swing rod 90. The tension adjusting base plate 95 is horizontally mounted on the lower end of the tension plate 1. The tension adjusting lever 93 is located below the tension adjusting elastic element 92 and its upper end is connected to the lower end of the tension adjusting elastic element 92. The lower end of the tension adjusting lever 93 moves through the tension adjusting base plate 95. The tension adjusting indicator rod 94 is horizontally sleeved on the tension adjusting lever 93 and moves through the scale groove 11. The tension adjusting knob 96 is threadedly connected to the lower end of the tension adjusting lever 93 and abuts against the bottom surface of the tension adjusting base plate 95.

[0052] In this embodiment, rotating the tension adjustment knob 96 pulls the tension adjustment lever 93 downward, which in turn pulls the tension adjustment elastic element 92 downward. The tension adjustment swing lever 90 is pulled downward by the tension adjustment elastic element 92 and swings downward around the tension adjustment lever fixing seat 91, causing the tension adjustment swing lever 90 to press against the counter-tension adjustment screw 237 of the brake shaft assembly 23. The brake shaft assembly 23 pulls the tension adjustment guide wheel assembly 21 to press against the damping brake assembly 22, and the damping brake assembly 22 generates resistance to the tension adjustment guide wheel assembly 21. The tension adjustment guide wheel assembly 21 rotates slower, increasing the tension of the wire wound on it. When the tension of the wire on the anti-tension guide wheel 80 increases, the wire pulls the anti-tension rod 82 downwards. The anti-tension rod 82, through the anti-tension shaft 83, drives the anti-tension adjustment rod 89 upwards. The anti-tension adjustment rod 89 pulls the anti-tension adjustment elastic element 803 upwards, which in turn pulls the tension adjustment swing rod 90 upwards. The elastic force of the anti-tension adjustment elastic element 803 cancels out the elastic force of the tension adjustment elastic element 92, thus reducing the tension of the wire. When the tension is high, the elastic force of the anti-tension adjusting elastic element 803 is greater than that of the tension adjusting elastic element 92. The pressure of the tension adjusting swing rod 90 on the anti-tension adjusting screw 237 decreases, and the tension adjusting guide wheel assembly 21 experiences reduced damping, thus accelerating the feeding of the wire to alleviate its tension. When the wire tension is low, the elastic force of the anti-tension adjusting elastic element 803 is less than that of the tension adjusting elastic element 92. The pressure of the tension adjusting swing rod 90 on the anti-tension adjusting screw 237 increases, and the tension adjusting guide wheel assembly 21 experiences increased damping, thus slowing down the feeding of the wire to increase its tension. The force can dynamically adjust the damping of the damping brake assembly 22 on the tension adjustment guide wheel assembly 21 according to the change of wire tension, thereby adjusting the wire tension. This not only reduces the cost of configuring pressure sensors, control chips and motors, but also reduces the delay of the pressure sensors, control chips and motors jointly adjusting the wire tension. It improves the accuracy of wire tension adjustment in a timely manner, and thus effectively solves the problems of delayed operation and high cost of tensioners currently on the market that rely on the configuration of pressure sensors, control chips and motors to jointly adjust wire tension.

[0053] Reference Figure 11As shown, the threading knob assembly 10 includes a threading knob rod 101, a threading washer 102, a threading limiting rod 103, a threading rotating rod 104, a rotating top block 105, a threading knob 106, and a threading handle 107. The threading knob rod 101 is vertically mounted on the tension plate 1 via the threading washer 102. The threading rotating rod 104 is vertically mounted on the threading knob rod 101 and located on one side of the threading washer 102. One end of the rotating top block 105 is vertically mounted on one end of the threading knob rod 101. The threading limiting rod 103 is vertically mounted on the tension plate 1 and limits the rotation of the threading rotating rod 104. The threading knob 106 is mounted on the other end of the threading knob rod 101, and the threading handle 107 is mounted on the threading knob 106.

[0054] In this embodiment, rotating the threading knob 106 causes the threading knob rod 101 to rotate, which in turn causes the threading rotating rod 104 to rotate and simultaneously causes the rotating top block 105 to swing. The swinging rotating top block 105 pushes up the tension adjusting swing pressure rod 90 of the damping adjusting assembly 9, causing the tension adjusting swing pressure rod 90 to separate from the anti-tension adjusting screw 237 of the brake shaft assembly 23. The threading limiting rod 103 blocks the threading rotating rod 104 to abut against the rotating top block 105 and limit the lifting of the tension adjusting swing pressure rod 90. At this time, the tension adjusting guide wheel assembly 21 is not damped by the damping brake assembly 22, and the tension adjusting guide wheel assembly 21 can rotate freely, which facilitates threading the tension adjusting guide wheel assembly 21.

[0055] Reference Figure 12 As shown, the cleaning component 3 includes a wool felt fixing block 30, a first wool felt 31, a second wool felt 32, a wool felt floating block 33, a wool felt fixing shaft 34, and a wool felt fixing knob 35. The wool felt fixing block 30 is mounted on the tension plate 1. The wool felt fixing shaft 34 passes through the center of the wool felt fixing block 30 and is threadedly connected to the wool felt fixing block 30. The wool felt floating block 33 is mounted on one end of the wool felt fixing shaft 34 and is located on one side of the wool felt fixing block 30. The first wool felt 31 and the second wool felt 32 are arranged side by side and are mounted together between the wool felt fixing block 30 and the wool felt floating block 33. The wool felt fixing knob 35 is mounted on the other end of the wool felt fixing shaft 34.

[0056] In this embodiment, the wire passes between the first wool felt 31 and the second wool felt 32. During the wire conveying process, the first wool felt 31 and the second wool felt 32 clean the wire. Twisting the wool felt fixing knob 35 in both directions rotates the wool felt fixing shaft 34 in both directions. The wool felt fixing shaft 34 tightens or loosens the wool felt fixing block 30 and the wool felt floating block 33 to clamp or loosen the first wool felt 31 and the second wool felt 32. This allows for the adjustment of the tightness of the clamping of the wire by the first wool felt 31 and the second wool felt 32, ultimately achieving the effect of adjusting the cleaning of the wire.

[0057] Reference Figure 1 , Figure 3 and Figure 10 As shown, the working process of this mechanical adjustable tension self-balancing wire tensioner is as follows: the wire is sequentially conveyed from the inlet limit frame 4, passing through the cleaning component 3, the damping braking mechanism 2, the wire feed guide roller 6, and the wire guide roller 7 to the anti-tension adjustment component 8, and then conveyed out through the anti-tension guide roller 80 of the anti-tension adjustment component 8. During the conveying process, the cleaning component 3 cleans the wire that is conveyed through it, the damping braking mechanism 2 adjusts the tension of the wire that is conveyed through it, the wire guide roller 7 guides and limits the wire that is conveyed through it, and the anti-tension adjustment component 8 tensions the wire that is conveyed through it. The overall structural design of the wire not only enables the transmission, cleaning, and guidance of the wire, but also allows for dynamic adjustment of the damping braking assembly 22's damping of the tension adjusting guide wheel assembly 21 to regulate the wire tension without the need for pressure sensors, control chips, and motors. This reduces the cost of configuring pressure sensors, control chips, and motors, while overcoming the delay problem inherent in adjusting wire tension using pressure sensors, control chips, and motors, thus significantly improving the accuracy and efficiency of wire tension adjustment.
