[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.
[0020] Embodiment 1, refer to Figure 1This embodiment is an active cable feeding device, including a bracket 1, a rotating shaft 2 for mounting a cable reel on the bracket, a motor on the bracket, a first pulley 4 on the motor shaft of the motor, a second pulley 5 on the rotating shaft, and a belt 6 fitted onto the first and second pulleys; a first feeding wheel 7 and a second feeding wheel 8 are provided on one side of the rotating shaft, both of which are rotatably connected to the bracket, the height of the first feeding wheel is less than the height of the rotating shaft, and the height of the second feeding wheel is greater than the height of the first feeding wheel; a third feeding wheel 9 is provided directly above the second feeding wheel, corresponding to the position of the second feeding wheel, and is rotatably connected to the bracket. The third feeding wheel is positioned close to the second feeding wheel to prevent the cable from moving upwards and detaching from the second feeding wheel. In this embodiment, the first feeding wheel, the second feeding wheel, and the third feeding wheel can use pulleys or rotating shafts, etc.
[0021] When using the above-mentioned active cable feeding device, the cable reel 18 is fixed on the rotating shaft. The cable is wound in the manner shown by the dotted line in the figure and then placed on the external operating machine for operation. When it is difficult for the external operating machine to pull the cable reel to rotate, the motor is started to drive the rotating shaft to rotate, which in turn drives the cable reel to rotate and feed the cable. This eliminates the need for manual dragging to assist in feeding the cable, reduces labor costs, and makes the feeding more stable.
[0022] In practical use, the motor can also be connected to a controller to control the motor speed; the controller can be a microcontroller. In actual manufacturing, the shaft and bracket can be connected using existing methods. As one implementation method: see [link to implementation details]. Figure 1 , Figure 3 and Figure 4 The bracket includes a first bracket 1-1 and a second bracket 1-2. Both the first and second brackets have notches 1-4 at their top ends. The rotating shaft passes through and is located within the notches. Two washers 10 and two nuts 11 are fitted onto the rotating shaft, and the two nuts are threadedly connected to the rotating shaft. This facilitates the removal and placement of the rotating shaft for cable reel installation. In actual manufacturing, blocking blocks can be installed near both ends of the rotating shaft to prevent lateral movement along the notches. Alternatively, the length of the rotating shaft can be greater than the distance between the two notches. To increase the bracket's stability, see [reference needed]. Figure 3 One or more crossbeams 1-3 are fixed between the first bracket and the second bracket. One end of the crossbeam is fixedly connected to the first bracket, and the other end is fixedly connected to the second bracket.
