[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. In order to make the above-mentioned objects, features and advantages of the present application more apparent and understandable, many specific details are set forth in the following description in order to provide a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0029] First embodiment: See Figures 1-4 A wire feeding machine includes a body 1 and a wire spool 2 rotatable on the body 1, and also includes a wire guide mechanism 3 for leading out and winding wires from the wire spool 2, a drive mechanism 4 for driving the wire spool 2 to rotate, a control device 501 and a wire encoder 502. The conductor mechanism 3 includes a fixed conductor group 301 and a movable conductor group 302 that moves up and down. The lead wire from the coil 2 passes through the fixed conductor group 301 and the movable conductor group 302 in sequence and then returns to the fixed conductor group 301 for output. The drive mechanism 4 and the pull encoder 502 are electrically connected to the control device 501. The movable end of the pull encoder 502 is connected to the movable conductor group 302 and is used to detect the up and down position of the movable conductor group 302 to adjust the operation of the drive mechanism 4.

[0030] The control device 501 and the wire encoder 502 form the detection mechanism 5. The control device 501 includes a control circuit board and electrical components such as chips mounted on the control circuit board.

[0031] The wire feeding machine uses the fixed wire group 301 and the movable wire group 302 of the wire feeding mechanism 3 to allow the wire to be wound along a specific path. The movable wire group 302 moves up and down during the feeding process, achieving buffer adjustment of the feeding tension. The detection mechanism 5 uses a combination of control device 501 and wire encoder 502 to replace the existing linear arrangement of multiple proximity switches. The wire encoder 502 is directly connected to the movable wire group 302. When the movable wire group 302 moves up and down, it can accurately detect its vertical displacement, avoiding the problem of a single sensor failure affecting the detection accuracy and improving detection stability. The control device 501 is electrically connected to the wire encoder 502 and the drive mechanism 4 respectively. It can adjust the movement of the movable wire group 302 and the rotation speed of the drive mechanism 4 in real time according to the displacement detection results. It can be simply understood as adjusting the rotation speed of the drive mechanism 4 according to the displacement of the movable wire group 302.

[0032] The draw-wire encoder 502 contains a precision rotating wheel (encoder disk) and a spring-driven take-up mechanism. When the measuring wire is pulled out of the encoder's housing, it rotates the wheel; as the wire retracts, the spring ensures the cable remains taut. An internal photoelectric or magnetoelectric sensor records the "angle" and "number of rotations" of the wheel, thus detecting the height position of the movable lead assembly 302 during its vertical movement. Using a single draw-wire encoder 502 effectively replaces the existing technology that uses a row of inductive switches for detection.

[0033] The conductor mechanism 3 is equipped with an inductive switch for detecting when the movable conductor group 302 moves to its limit position; The inductive switch includes two limit switches, a first limit switch 6 and a second limit switch 7, which are arranged vertically and vertically. By providing two limit switches, the movable conductor assembly 302 is prevented from exceeding its travel range.

[0034] The wire mechanism 3 includes a frame 303 fixed on the body 1. The inductive switch and the fixed wire assembly 301 are both fixed outside the frame 303. The frame 303 is provided with a guide rail 8 and a slider 9 that slides on the guide rail 8. The movable wire assembly 302 is fixedly connected to the slider 9. The pull-wire encoder 502 is fixed inside the frame 303.

[0035] The pull-wire encoder 502 is located below the movable wire group 302; the movable wire group 302 is located below the fixed wire group 301.

[0036] The guide rail 8 and slider 9 are designed to allow the movable wire assembly 302 to slide smoothly. The wire encoder 502 can be fixed in the frame 303 by screws or other fasteners, which facilitates the smooth connection between the wire encoder 502 and the movable wire assembly 302. The wire encoder 502 is fixed in the frame 303 as a stationary reference point.

[0037] The movable wire assembly 302 includes a movable block 304 and a lower guide wheel 305. The lower guide wheel 305 is rotatably connected to the movable block 304. The movable block 304 is fixedly connected to the slider 9. The movable block 304 is provided with a connector 306 that extends into the frame 303 and is connected to the wire encoder 502.

[0038] The connector 306 extends into the frame 303 and is connected to the wire encoder 502. The connector 306 ensures that the wire encoder 502 is triggered during the up and down movement of the movable wire group 302, and the connection direction between the connector 306 and the wire encoder 502 is consistent with (parallel to) the up and down movement direction of the movable wire group 302.

[0039] The frame 303 has a clearance groove for the corresponding connector 306, which moves up and down along the trajectory of the movable wire assembly 302. The connector 306 extends into the frame 303 along the clearance groove and connects to the wire encoder 502.

[0040] The lower guide wheel 305 is provided with a plurality of spaced first guide grooves, and the shaft of the lower guide wheel 305 is provided with a first limiting member 307, and a first limiting gap is formed between the inner side of the first limiting member 307 and the first guide groove.

[0041] The first limiting gap can laterally limit the wire, preventing it from coming out of the first guide groove and ensuring that the wire always moves along the set path.

[0042] The fixed conductor assembly 301 includes a fixed block 308 and an upper guide wheel 309. The fixed block 308 is fixedly connected to the frame 303, and the upper guide wheel 309 is rotatably connected to the fixed block 308. The upper guide wheel 309 is provided with a plurality of spaced second guide grooves. The rotating shaft of the upper guide wheel 309 is provided with a second limiting member 310, and a second limiting gap is formed between the inner side of the second limiting member 310 and the second guide groove.

[0043] The second limiting gap can laterally limit the wire, preventing it from coming out of the second guide groove and ensuring that the wire always moves along the set path.

[0044] The coil 2 is detachably mounted on the body 1; The machine body 1 is equipped with a first frame 10, on which a rotating first connecting shaft 12 is mounted. The output end of the drive mechanism 4 is connected to the first connecting shaft 12. The spool 2 is equipped with a bushing 13 and a fastener 14. When the spool 2 is installed, the first connecting shaft 12 is inserted into the bushing 13, and the fastener 14 is inserted into the bushing 13 and locks the first connecting shaft 12. When the spool 2 is disassembled, the fastener 14 loosens the first connecting shaft 12. The fastener is a screw. When the first connecting shaft 12 rotates, it drives the spool 2 to rotate. This disassembly and assembly method is suitable for lightweight spools 2.

[0045] The machine body 1 is equipped with a frequency converter 11 for cooperating with the adjustment drive mechanism 4, and the frequency converter 11 is electrically connected to the control device 501. The frequency converter 11 and the control device 501 are installed on the first frame 10.

[0046] The drive mechanism 4 includes a motor 401 and a reducer 402. The output shaft of the motor 401 is connected to the input end of the reducer 402, and the output end of the reducer 402 is connected to the corresponding first connecting shaft 12. The drive mechanism 4 is installed on the first frame 10.

[0047] Second embodiment: See Figures 5-10The wire feeding machine differs from the first embodiment in that the machine body 1 is provided with a second frame 15, and the second frame 15 is provided with a plurality of second connecting shafts 16 arranged at intervals along an arc. Each second connecting shaft 16 is rotatably connected to the second frame 15. The second connecting shaft 16 is used to support the bottom of the wire reel 2. One of the second connecting shafts 16 is connected to the output end of the drive mechanism 4 for transmission. The wire reel 2 is detachably mounted on the plurality of second connecting shafts 16.

[0048] The second connecting shaft 16, which is connected to the drive mechanism 4, is provided with a rolling wheel 17 for supporting the bottom of the spool 2. The rolling wheel 17 is provided with anti-slip texture 1701 to increase the contact friction area with the spool 2. The anti-slip texture 1701 increases the contact friction area with the bottom of the spool 2, ensuring efficient power transmission and preventing slippage between the spool 2 and the rolling wheel 17 from affecting the line feeding speed.

[0049] The second frame 15 has a slide plate 18 at one end for guiding the cable reel 2 to be installed or removed from several second connecting shafts 16, and the side of the slide plate 18 has a limiting edge 1801 for limiting the cable reel 2.

[0050] The slide plate 18 at one end of the second frame 15 facilitates the sliding of the spool 2 into or out of multiple second connecting shafts 16; the limiting edge 1801 can prevent the spool 2 from lateral displacement during loading and unloading. This disassembly and assembly method is suitable for heavier spools 2.

[0051] The drive mechanism 4 includes a motor 401 and a reducer 402. The output shaft of the motor 401 is connected to the input end of the reducer 402, and the output end of the reducer 402 is connected to the corresponding second connecting shaft 16. The drive mechanism 4 is mounted on the second frame 15.

[0052] The frequency converter 11 and the control device 501 are mounted on the wire mechanism 3.

[0053] All other parts not described herein are the same as in the first embodiment and will not be described in detail here.

[0054] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
