Embodiment 1
[0069] See attached figure 1 , attached figure 2 and attached Figure 4 As shown, a tension controller suitable for active / passive wire feeding mode includes a base plate 1 and a tension setting controller 3, the base plate 1 is provided with a tension wire wheel 2 and a tension adjustment mechanism, the tension wire wheel 2 Rotatingly supported on the base plate 1, the tension adjustment mechanism includes a tension rod 41, an extension spring 42 and an extension spring adjustment device, and the extension spring 42 is arranged between the tension rod 41 and the extension spring adjustment device.
[0070] Described extension spring adjusting device comprises extension spring block 43, guide rail, screw mandrel and motor 45, and described extension spring block 43 is moved and arranged on the guide rail and is fixedly connected with an adjustment slide block 47, between adjustment slide block 47 and screw mandrel Through threaded connection, the output shaft of the motor 4...
Embodiment 2
[0080] The difference between this embodiment and Embodiment 1 is: see the attached image 3 As shown, in the first embodiment, the tension sensor is integrated with the tension setting controller 3; repeat.
Embodiment 3
[0082] The difference between this embodiment and Embodiment 1 is: see the attached Figure 5 and attached Figure 7 As shown, the extension spring adjusting device includes an extension spring rod 48, an extension spring rod rotating shaft and a motor 45;
[0083] The extension spring rod 48 is rotatably supported on the base plate 1 through the extension spring rod shaft, and the extension spring rod rotation shaft is connected to the output shaft of the motor 45 through a worm gear mechanism;
[0084] One end of the tension rod 41 is rotatably supported on the base plate 1;
[0085] One end of the extension spring 42 is fixed on the tension rod 41 , and the other end of the extension spring 42 is fixed on the extension spring rod 48 .
[0086] The rest are the same as those in Embodiment 1, and will not be repeated here.
