[0002] A coil feeding machine is provided on the wire feeding end of the wire drawing machine, which can straighten and correct the coil and send it to the eye die of the wire drawing machine. An adjustable guide wheel structure (such as Figure 4 and Figure 5 As shown), it includes a guide wheel bracket 2, a slider and a fixed block are provided on the guide wheel bracket, and guide wheels 12 are provided on the slider and the fixed block. An adjusting screw 11 passes through the slider and the fixed block, and the adjusting screw 11 is threadedly connected to the slider. That is, by rotating the adjusting screw 11, the slider can be moved up and down on the guide wheel bracket, thereby adjusting the distance between the two guide wheels 12 to adapt to different thicknesses of disk wires.

[0003] However, the adjusting screw 11 is usually adjusted manually, and the rotation of the adjusting screw 11 is very laborious, the adjustment operation takes a long time, the efficiency is low, and the adjustment is often not in place or excessive. In addition, the wire vibrates when passing through the guide wheel, causing the adjusting screw 11 to rotate due to the vibration, resulting in unstable adjustment of the guide wheel. Utility Model Content

[0004] In response to the deficiencies in the prior art, the utility model provides a coil wire feeding machine with an adjustable guide wheel using a driving mechanism such as a hydraulic cylinder. Manual adjustment of the guide wheel is unnecessary, which greatly improves the adjustment efficiency and accuracy.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a coil wire feeder with adjustable guide wheels, comprising a wire feeder bracket, a guide wheel bracket being provided on one side of the wire feeder bracket, a first slider and a second slider being slidably connected to the guide wheel bracket, guide wheels being provided on both the first slider and the second slider, a driving mechanism being provided on the guide wheel bracket, the driving mechanism being connected to the first slider, and a fine-tuning mechanism being provided between the second slider and the guide wheel bracket.

[0006] Furthermore, the driving mechanism includes a driving bracket, a hydraulic cylinder is provided on the driving bracket, and a piston rod of the hydraulic cylinder is connected to the first sliding block.

[0007] Furthermore, the fine-tuning mechanism includes a fixing screw fixed to the guide wheel bracket, the fixing screw passes through the second slider, an adjusting nut is threadedly connected to the fixing screw, and the adjusting nut is supported below the second slider.

[0008] Furthermore, a through slot is provided on the guide wheel bracket, and the through slot corresponds to the adjusting nut.

[0009] Furthermore, a clamping bolt is provided on the guide wheel bracket, and the clamping bolt is threadedly connected to the guide wheel bracket, and the end of the clamping bolt is in contact with the fixing screw.

[0010] Compared with the prior art, the beneficial effect of the present invention is that the first up and down movement is adjusted by replacing the original screw with a driving mechanism, thereby eliminating the need for manual adjustment, greatly improving the adjustment efficiency and accuracy. At the same time, because the first slider is connected to the piston rod of the hydraulic cylinder, it will not move arbitrarily due to vibration during wire feeding, thereby improving stability.

[0019] Refer to Figures 1 to 5 for further description of the present utility model.

[0020] A wire feeding machine with an adjustable guide wheel includes a wire feeding machine bracket 1. On one side of the wire feeding machine bracket 1, there is a guide wheel 12 bracket 2. A first slider 3 and a second slider 4 are slidably connected to the guide wheel 12 bracket 2. Guide wheels 12 are provided on both the first slider 3 and the second slider 4. A driving mechanism is provided on the guide wheel 12 bracket 2, and the driving mechanism is connected to the first slider 3. A fine-tuning mechanism is provided between the second slider 4 and the guide wheel 12 bracket 2.

[0021] As Figures 1 to 3 shown, the driving mechanism is used to replace the original screw rod to adjust the up and down movement of the first guide wheel 12, so that manual adjustment is no longer required, greatly improving the adjustment efficiency and accuracy. At the same time, since the first slider 3 is connected to the piston rod of the oil pressure cylinder 6, it will not move randomly during wire feeding due to vibration, improving stability.

[0022] In addition, fine-tuning of the second guide wheel 12 is added to improve the stability during wire conveying.

[0023] As Figures 1 to 5 shown, the guide wheel 12 bracket 2 is in a "U" shape, and its upper and lower ends are connected to the wire feeding machine bracket 1. The first slider 3 and the second slider 4 are located in the groove of the guide wheel 12 bracket 2. The first slider 3 and the second slider 4 are in a "H" shape, and the grooves on both sides thereof cooperate with the sides of the guide wheel 12 bracket 2 and the wire feeding machine bracket 1 to ensure the stability of the first slider 3 and the second slider 4 during sliding.

[0024] As Figures 1 to 3 shown, in the preferred embodiment of the present invention, the driving mechanism includes a driving bracket 5. An oil pressure cylinder 6 is provided on the driving bracket 5, and the piston rod of the oil pressure cylinder 6 is connected to the first slider 3.

When the adjusting nut 8 is rotated, the adjusting nut 8 moves up and down on the fixed screw 7, which can push the second slider 4 to rise or the second slider 4 to fall.

[0030] like Figure 2 As shown, in this embodiment, preferably, a through slot 9 is provided on the guide wheel 12 bracket 2, and the through slot 9 corresponds to the adjusting nut 8, which facilitates the adjustment and rotation of the adjusting nut 8 from the side of the guide wheel 12 bracket 2.

[0031] like Figure 2 As shown, in this embodiment, preferably, a clamping bolt 10 is provided on the guide wheel 12 bracket 2, and the clamping bolt 10 is threadedly connected to the guide wheel 12 bracket 2, and the end of the clamping bolt 10 is in contact with the fixing screw 7.
