DETAILED DESCRIPTION

[0018] The following is combined with Figure 1-3 The specific implementation modes of the present utility model are further described in detail.

[0019] Depend on Figure 1-3The utility model provides a wire feeding device for cable processing, comprising a bracket 10, a wire feeding tube 20 arranged on the bracket 10 for straightening the cable, and a winding roller 30 rotatably mounted on the bracket 10 for winding the cable. A straightening mechanism for straightening the cable is arranged in the wire feeding tube 20. When the cable passes through the wire feeding tube 20, the straightening mechanism can straighten the bent cable, so that the wire feeding device can transport the straightened cable outward. The main improvements of the utility model are:

[0020] The bracket 10 is provided with a movable frame 40 that slides along the length direction, and the wire feeding tube 20 is rotatably installed on the upper end of the movable frame 40 through a horizontally arranged rotating shaft 201. First, the wire feeding tube 20 is installed on the movable movable frame 40. When feeding the wire, the horizontal position of the wire feeding tube 20 can be adjusted according to the position of the cable on the winding roller 30 when the cable is unwound to prevent severe bending of the cable. In addition, the wire feeding tube 20 is installed on the movable frame 40 through a rotating shaft 201, so that the wire feeding tube 20 can swing in the vertical direction. For example, when there are more cables on the winding roller 30, the end of the wire feeding tube 20 close to the winding roller 30 is correspondingly raised. When the cable on the winding roller 30 becomes less, the end of the wire feeding tube 20 close to the winding roller 30 is also correspondingly lowered. In this way, the degree of bending of the cable when entering the wire feeding tube 20 can be further reduced.

[0021] In order to facilitate the placement of the cable into the wire feeding tube 20, the wire feeding tube 20 includes a lower half tube 21 and an upper half tube 22. The lower half tube 21 is fixedly connected to the rotating shaft 201. The inner surfaces of the upper half tube 22 and the lower half tube 21 are rotatably installed with a pair of clamping wheels 23 along the length direction, and the upper half tube 22 can slide vertically upward on the lower half tube 21. The lower half tube 21 is provided with a fixing structure for fixing the upper half tube 22. The upper half tube 22 can be removed from the lower half tube 21. When inserting the cable, the upper half tube 22 can be moved upward to be removed. After the cable is placed on the surface of the clamping wheel 23 on the lower half tube 21, the upper half tube 22 is covered on the lower half tube 21, so that the cable is clamped between the clamping wheels 23 of the upper half tube 22 and the lower half tube 21. In this way, when the cable moves in the wire feeding tube 20, the cable can be straightened by the limiting effect of the clamping wheel 23.

[0022] The support 10 is provided with a driving mechanism 50 for driving the movable frame 40 to slide on the surface of the support 10 .

[0023] In this embodiment, the driving mechanism 50 includes a slide rail 51 fixed on the surface of the bracket 10, a bidirectional threaded screw 52 rotatably installed in the slide rail 51, and a stepper motor 53 fixed on the surface of the bracket 10. The output shaft of the stepper motor 53 is threadedly connected to the end of the bidirectional threaded screw 52. The lower end of the movable frame 40 is slidably connected in the slide rail 51. The bidirectional threaded screw 52 is threadedly connected to the lower end of the movable frame 40. The external power supply of the stepper motor 53 is turned on to drive the bidirectional threaded screw 52 to rotate. When the bidirectional threaded screw 52 rotates, it drives the movable frame 40 to move back and forth, so that the winding roller 30 is wound evenly. On the contrary, when unwinding and feeding the wire, the bidirectional threaded screw 52 drives the movable frame 40 to move back and forth, so as to automatically adjust the position of the wire feeding tube 20 and reduce the bending of the cable.

[0024] Furthermore, a sprocket 24 is fixed to the shaft of the lower half tube 21, and a chain 25 is connected between the sprockets 24. A driving motor is fixed to the outside of the lower half tube 21, and the output shaft of the driving motor is drivingly connected to one of the sprockets 24. The driving motor drives one sprocket 24 to rotate, and the chain 25 drives the remaining sprockets 24 to rotate together, thereby driving the clamping wheel 23 of the lower half tube 21 to rotate, and the cable is moved under the action of friction to realize wire feeding.

[0025] In some embodiments, a slide groove 26 is embedded in the outer side surface of the lower half tube 21, and the lower sides of the upper half tube 22 are slidably inserted into the slide groove 26. The lower part of the upper half tube 22 can slide up and down in the slide groove 26 to adjust the distance between the upper and lower clamping wheels 23, thereby achieving cables of different thicknesses. In some embodiments, the fixing structure is a bolt 27 connected between the upper half tube 22 and the lower half tube 21. After adjusting the position of the upper half tube 22, the bolt 27 can be turned to lock it.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
