[0029] It should be noted that the bottom edge of the cutter body 513 is inclined, and the inclination angle is 60°.

[0030] The locking shaft portion 52 includes a locking shaft body 521, a plurality of locking shaft guide grooves 522 and a locking shaft plate group.

The locking shaft plate 523 is fixedly arranged on the front end side of the locking shaft body 521. The locking shaft plate holes 524 are all arranged through the locking shaft plate 523.

[0031] The fastening portion 53 includes a fastening ring group and a protrusion group. The fastening ring group includes a fastening ring 531, a plurality of outer guide strips 532 and a plurality of inner guide strips 533. The protrusion group includes a protrusion 534 and a limiting hole 535. The outer guide strips 532 are all fixedly arranged on the outer ring of the fastening ring 531, and the inner guide strips 533 are all fixedly arranged on the inner ring of the fastening ring 531. The protrusion 534 is fixedly arranged at the front end of the outer ring of the fastening ring 531, and the limiting hole 535 is penetrated through the protrusion 534.

[0032] The outer guide bar 532 is inserted into the corresponding cutter guide groove 512, and the inner guide bar 533 is inserted into the corresponding lock shaft guide groove 522, connecting the cutter part 51, the lock shaft part 52, and the fastening part 53 together to prevent the cutter part 51 and the fastening part 53 from rotating relative to the lock shaft part 52, so that the cutter body 513 cannot cut the metal wire.

[0033] A locking portion 54 and a handle portion 55 are provided on the front side wall of the fastening ring 531. The locking portion 54 includes a connecting block 541, a threaded rod 542, a threaded sleeve 543 and a limiting column 544. The handle portion 55 includes a handle body 551 and a plurality of convex strips 552. The handle body 551 is fixedly connected to the fastening ring 531. The convex strips 552 are all fixedly arranged on the outside of the handle body 551. The connecting block 541 is fixedly connected to the fastening ring 531. The threaded rod 542 is fixedly arranged above the connecting block 541. The threaded sleeve 543 is threadedly sleeved on the outer ring of the threaded rod 542. The limiting column 544 is fixedly arranged on the top of the threaded sleeve 543.

[0034] The diameter of the limiting column 544 is smaller than the diameter of the cutting plate hole 518 and the locking shaft plate hole 524, ensuring that the limiting column 544 can be smoothly inserted into the cutting plate hole 518 and the locking shaft plate hole 524, fixing the cutting part 51 and the fastening part 53 on the locking shaft part 52, and preventing the cutting part 51 and the fastening part 53 from falling off from the locking shaft part 52.

[0035] There are scales engraved on the cutting plate 517. When the limiting column 544 extends into the corresponding cutting plate hole 518, the scale corresponding to the cutting plate hole 518 is the distance moved by the fastening portion 53. Since the bottom edge of the cutting body 513 is inclined and the inclination angle is 60°, the length of the cutting body 513 protruding from the fixed-length wheel 511 can be calculated based on the distance moved by the fastening portion 53 according to the side length calculation rule of the right triangle. The circumference of the circular trajectory formed by the radius of the fixed-length wheel 511 plus the length is the length of the cut wire.

[0036] Since the knob 62 is rotatably connected to the baffle 61, the screw 63 is fixedly connected to the pressure-adjusting shaft 64, and the knob 62 is threadedly connected to the screw 63, turning the knob 62 will drive the screw 63 to slide up and down, and the screw 63 drives the pressure-adjusting shaft 64 to slide up and down in the guide groove 32, thereby adjusting the distance between the wire supply pressure wheel 7 and the fixed-length wheel portion 5. Turning the knob 62 causes the screw 63 to move upward, and the distance between the wire supply pressure wheel 7 and the fixed-length wheel portion 5 increases, making it easier for the metal wire to pass through. The metal wire on the wire supply wheel 2 is pulled out, and one end of the metal wire is passed through the left wire supply tube 15, and passed between the wire supply pressure wheel 7 and the fixed-length wheel portion 5, and finally inserted into the right wire supply tube 16; the knob 62 is rotated in the opposite direction to drive the screw 63 to move downward, and the screw 63 pushes the wire supply pressure wheel 7 downward through the pressure-adjusting shaft 64, and presses on the outer ring of the fixed-length wheel 511, clamping the metal wire between the two. The servo motor 31 is started, and the servo motor 31 drives the lock shaft body 521 to rotate. The lock shaft body 521 drives the fixed-length wheel 511 to rotate through the fastening ring 531. The fixed-length wheel 511 drives the wire supply pressure wheel 7 to rotate together through the friction force, and the metal wire is pushed forward along the right wire supply tube 16. When the cutter body 513 follows the fixed-length wheel 511 to rotate to the intersection of the wire supply pressure wheel 7 and the fixed-length wheel 511, the cutter body 513 cuts the metal wire under the pressure of the wire supply pressure wheel 7. Since the height of the cutter body 513 protruding from the fixed-length wheel 511 remains unchanged, the metal wire after cutting The lengths of the wires are equal and are equal to the circumference of the outer edge trajectory of the cutter body 513; after the metal wire is cut, the servo motor 31 stops working, turns the knob 62, lifts the wire supply pressure wheel 7, pulls the metal wire on the left side, passes it through between the wire supply pressure wheel 7 and the fixed-length wheel 511, and extends it into the right wire supply tube 16, and then presses the wire supply pressure wheel 7 on the fixed-length wheel 511, and the servo motor 31 works again, continues to push the metal wire of the left wire supply tube 15 to the right wire supply tube 16, and pushes the previously cut metal wire in the right wire supply tube 16 forward, and repeats this cycle to complete the wire supply.

[0037] When the length of the cut wire needs to be changed, the threaded sleeve 543 is rotated to move it downward along the threaded rod 542, and the limiting column 544 is pulled out from the cutting plate hole 518 and the locking shaft plate hole 524, so that the limiting column 544 loses the restriction on the cutting plate 517 and the locking shaft plate 523, and the rotary handle 55 is pinched and pulled outward to pull the fastening part 53 out of the inside of the cutting part 51, and the fastening ring 531 no longer lifts the cutting body 513 upward, and the spring 516 rebounds and pushes the cutting body 513 to slide into the fixed length wheel 511 through the slider 515. The top surface of the cutting body 513 is lower than the outer surface of the fixed length wheel 511 to prevent the cutting body 513 from being accidentally injured when replacing the cutting part 51; after the fastening part 53 is pulled out, the cutting part 51 is removed from the locking shaft part 52, and a fixed length wheel with a suitable radius is replaced. 511, put the new fixed-length wheel 511 on the locking shaft part 52, and then insert the fastening part 53 into the gap between the cutter part 51 and the locking shaft part 52, so that the outer guide strip 532 is located in the cutter guide groove 512, the inner guide strip 533 is located in the locking shaft guide groove 522, and the cutter plate 517 is located directly above the locking shaft plate 523, and the limiting column 544 is located directly below the cutter plate 517 and the locking shaft plate 523, and the fastening part 53 is pushed inward. Since the bottom edge of the cutter body 513 is inclined and the outer end is higher than the inner end, when the fastening ring 531 moves forward, the cutter body 513 is pushed upward and the cutter body 513 is pushed out of the fixed-length wheel 511, which is convenient for cutting the metal wire, and then the threaded sleeve 543 is rotated to push the limiting column 544 into the locking shaft plate hole 524 and the cutter plate hole 518 in sequence. The cutter portion 51 and the fastening portion 53 are fixed on the locking shaft portion 52 to prevent the cutter portion 51 and the fastening portion 53 from being thrown out when the servo motor 31 drives the locking shaft portion 52 to rotate. If the radius of the replaced fixed-length wheel 511 is smaller, it is necessary to move the wire pressing wheel 7 downward to press the metal wire onto the fixed-length wheel 511. If the radius of the replaced fixed-length wheel 511 is larger, it is necessary to move the wire pressing wheel 7 upward to press the metal wire onto the fixed-length wheel 511. If the length of the metal wire is fine-tuned, the cutter portion 51 does not need to be replaced. When the fastening portion 53 is pulled out from between the cutter portion 51 and the locking shaft portion 52, the cutter body 513 moves downward under the action of the spring 516, the length of the protruding fixed-length wheel 511 is reduced, the circumference of its trajectory is reduced, the length of the cut metal wire is correspondingly reduced, and the fastening portion 513 is fixed. When the cutting blade 51 is pushed inwardly between the cutting blade part 51 and the locking shaft part 52, the fastening ring 531 pushes the cutting blade body 513 to move upward on the spring 516, the length of the protruding fixed-length wheel 511 increases, the circumference of its track increases, and the length of the cut metal wire increases accordingly; after adjusting the position of the fastening part 53, the limiting column 544 is extended into the corresponding cutting blade plate hole 518 and the locking shaft plate hole 524, and the scale on the cutting blade plate 517 shows the extended length of the cutting blade body 513, and then the length of the cut metal wire can be determined. Through this precise control method, the amount of coated metal wire can be accurately controlled, thereby realizing the precise control of the deposition amount of the coating material, and then accurately controlling the thickness of the coating, effectively improving the uniformity and consistency of the coating, and then improving the quality of subsequent coated products.
