[0023] See also Figure 1 to Figure 2 , the utility model provides a technical solution:

[0024] Embodiment 1, an active wire paying-off device for a wire cutting machine, the active wire paying-off device for a wire cutting machine comprises: a mounting base 1.

[0025] Specifically, one side of the mounting base 1 is rotatably connected with a mounting shaft 2, one end of the mounting shaft 2 is sleeved and fixed with a winding drum 3, a wire 9 is arranged on the side of the winding drum 3, and one side of the mounting base 1 is fixedly connected with a stepper motor 4, a belt 41 is arranged between the rotating shaft of the stepper motor 4 and the mounting shaft 2, and the stepper motor 4 drives the mounting shaft 2 to rotate through the belt 41, and then drives the winding drum 3 to rotate, thereby controlling the winding drum 3 to actively convey the wire 9;

[0026] Furthermore, the mounting frame 5 is located on one side of the mounting base 1 and is fixedly connected to the mounting base 1. One side of the mounting frame 5 is rotatably connected to two symmetrically arranged No. 1 guide wheels 53. The inner side of the mounting frame 5 is slidably connected to a slider 6. One side of the slider 6 is rotatably connected to a No. 2 guide wheel 7. The side of the No. 2 guide wheel 7 is fixedly connected to two symmetrically arranged restraining rods 71. One end of the wire 9 passes through the first No. 1 guide wheel 53, the No. 2 guide wheel 7 and the other No. 1 guide wheel 53 closest to the winding drum 3 in turn. The wire 9 output from the winding drum 3 enters the traction machine Before the wire 9 enters the traction mechanism, it will first bypass the first guide wheel 53 closest to the winding disk 3, then bypass the second guide wheel 7, and finally bypass the other guide wheel 53 to enter the traction mechanism. Because the first guide wheel 53 and the second guide wheel 7 are both rotatably installed, the friction generated when the wire 9 slides can be reduced, and the dead weight of the slider 6 and the second guide wheel 7 will also keep the wire 9 in a relatively tight state at all times, so that the wire 9 with a fixed output route will not be tangled, and the restraint rod 71 on the second guide wheel 7 can further separate the wire 9 to ensure the safety of the wire 9.

[0027] For the safety of the wire 9, one end of the mounting frame 5 of the present application is fixedly connected to a hydraulic cylinder 8, the telescopic rod of the hydraulic cylinder 8 is plugged into the mounting frame 5 and one end of the telescopic rod of the hydraulic cylinder 8 is fixedly connected to a mounting block 81, one end of the mounting block 81 is fixedly connected to a pressure sensor 82, the pressure sensor 82 and the slider 6 are positioned correspondingly and in contact with each other, when the wire 9 is driven by the traction mechanism, it will drive the No. 2 guide wheel 7 and the slider 6 to slide upward, when the slider 6 slides, it will apply pressure to the pressure sensor 82, after exceeding the permitted range, the hydraulic cylinder 8 will drive the mounting block 81 and the pressure sensor 82 to slide upward, so that the slider 6 can slide further, so that the wire 9 will not be stretched too tight, thereby ensuring the safety of the wire 9.

[0028] In order to facilitate the installation of the No. 1 guide wheel 53, two symmetrically arranged connecting shafts 51 are fixedly connected to one side of the mounting frame 5 of the present application, and the No. 1 guide wheel 53 and the connecting shafts 51 are rotatably connected, so that the No. 1 guide wheel 53 can be rotatably installed on the mounting frame 5.

[0029] In order to facilitate the sliding installation of the slider 6, two guide rods 52 are fixedly connected to the inner side of the mounting frame 5 of the present application, and the slider 6 and the two guide rods 52 are all slidably connected. The guide rods 52 can further limit the sliding trajectory of the slider 6 while ensuring that the slider 6 is slidably installed on the mounting frame 5.

[0030] In order to facilitate the installation of the No. 2 guide wheel 7 and the safety of the slider 6, a support shaft 61 is fixedly connected to one side of the slider 6 of the present application. The support shaft 61 can facilitate the No. 2 guide wheel 7 to be rotatably installed on the slider 6. The No. 2 guide wheel 7 and the support shaft 61 are rotatably connected. A plurality of springs 62 are arranged between the slider 6 and the mounting frame 5, and the plurality of springs 62 are fixedly connected to the mounting frame 5. The springs 62 can allow the slider 6 to better buffer when falling, thereby avoiding direct collision between the slider 6 and the mounting frame 5.

[0031] In order to facilitate the installation of the shaft rod 2 and the stepper motor 4, a vertical pole 11 is fixedly connected to one side of the installation base 1 of the present application, and a fixing frame 12 is fixedly connected to one side of the vertical pole 11. The installation shaft rod 2 and the vertical pole 11 are rotatably connected, and the stepper motor 4 is fixedly connected to the fixing frame 12. The vertical pole 11 and the fixing frame 12 allow sufficient installation space for the installation shaft rod 2 and the stepper motor 4, allowing the winding reel 3 to be better installed.

[0032] In actual implementation, the wire 9 is first passed around the first guide wheel 53, the second guide wheel 7 and the other guide wheel 53 closest to the winding drum 3 in turn, and then the wire 9 is connected to the traction mechanism on the wire cutting machine, and the wire 9 will pass between the constraint rod 71 and the second guide wheel 7 when passing around the second guide wheel 7. After the wire 9 is installed, the hydraulic cylinder 8 controls the mounting block 81 and the pressure sensor 82 to slide down, thereby controlling the sliding block 6 to slide, so that the wire 9 is initially in a suitable tight state, and then the wire cutting machine and the stepper motor 4 are started. At this time, the traction opportunity pulls the wire 9 and the winding drum 3 will also rotate to output the wire 9 from the winding drum 3 to cooperate with the operation of the traction mechanism. Since the output trajectory of the wire 9 is fixed by the two guide wheels 53 and the second guide wheel 7, and with the cooperation of the self-weight of the slider 6 and the second guide wheel 7, the wire 9 will always be in a relatively tight state, thereby ensuring that the wire 9 will not be knotted or twisted.

[0033] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
