The guide groove 32 is arranged in front of the side wall of the power source housing. The guide rod 33 is located in the guide groove 32 and is fixedly connected to the power source housing. Grooves are opened on both sides of the guide groove 32. The ball 65 rolls in the groove, and the groove limits the ball 65 to prevent the screw 63 from skewing and being unable to vertically press the wire feeding pressure wheel 7 on the fixed-length wheel 511.

[0045] A support block 4 is arranged on the front side of the pressure regulating part 6. The support block 4 is slidably connected to the left support plate 17. In this embodiment, a servo motor is preferably used as the power source to drive the locking shaft body 521 to rotate.

The screw sleeve part includes a pressure regulating shaft 64, a number of balls 65 and a screw sleeve 66. The pressure regulating shaft 64 is slidably arranged in the guide groove 32, penetrates through the guide rod 33 and is slidably connected to the guide rod 33. The balls 65 are rotatably arranged at both end parts of the pressure regulating shaft 64. The screw sleeve 66 is threadedly sleeved on the outer circle of the pressure regulating shaft 64.

The screw sleeve 66 is rotatably connected to the wire feeding pressure wheel 7. Screwing the screw sleeve 66 onto the pressure regulating shaft 64 can install the wire feeding pressure wheel 7 on the side wall of the servo motor 31.

[0047] The fixed-length wheel part 5 further includes a locking shaft part 52 and a fastening part 53. The locking shaft part 52 is fixedly arranged in front of the side wall of the power source housing. The cutter part 51 is sleeved on the outer circle of the locking shaft part 52. The fastening part 53 is inserted between the cutter part 51 and the locking shaft part 52.

[0048] The cutter part 51 includes a locking shaft body group, a cutter body group and a cutter plate group.

The cutter body 513 is slidably connected to the fixed-length wheel 511. The receiving grooves 514 are located in the fixed-length wheel 511 and on both sides of the cutter body 513. The sliders 515 are slidably arranged in the receiving grooves 514. The springs 516 are located in the receiving grooves 514. The top ends of the springs 516 are fixedly connected to the fixed-length wheel 511, and the bottom ends are fixedly connected to the sliders 515. The cutter guide grooves 512 are all arranged on the inner wall of the fixed-length wheel 511. The cutter plate 517 is fixedly arranged on the front side surface of the fixed-length wheel 511. The cutter plate holes 518 are all penetrated through the cutter plate 517.

[0049] It should be noted that the bottom edge of the cutter body 513 is inclined, and the inclination angle is 60°.

[0050] The locking shaft part 52 includes a locking shaft body 521, a number of locking shaft guide grooves 522 and a locking shaft plate group. The locking shaft plate group includes a locking shaft plate 523 and a number of locking shaft plate holes 524. The locking shaft guide grooves 522 are all arranged on the outer circle of the locking shaft body 521. The locking shaft plate 523 is fixedly arranged on the front end side surface of the locking shaft body 521. The locking shaft plate holes 524 are all penetrated through the locking shaft plate 523.

[0051] The fastening part 53 includes a fastening ring group and a bump group. The fastening ring group includes a fastening ring 531, a plurality of outer guide bars 532 and a plurality of inner guide bars 533. The bump group includes a bump 534 and a limiting hole 535. The outer guide bars 532 are all fixedly arranged on the outer ring of the fastening ring 531, the inner guide bars 533 are all fixedly arranged on the inner ring of the fastening ring 531, the bump 534 is fixedly arranged at the front end of the outer ring of the fastening ring 531, and the limiting hole 535 penetrates through the bump 534.

[0052] 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, preventing 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.

[0053] The front side wall of the fastening ring 531 is provided with a locking part 54 and a rotating handle part 55. The locking part 54 includes a connecting block 541, a threaded rod 542, a threaded sleeve 543 and a limiting post 544. The rotating handle part 55 includes a rotating handle body 551 and a plurality of convex strips 552. The rotating handle body 551 is fixedly connected with the fastening ring 531, the convex strips 552 are all fixedly arranged on the outer side of the rotating handle body 551, the connecting block 541 is fixedly connected with 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, and the limiting post 544 is fixedly arranged at the top end of the threaded sleeve 543.

[0054] The diameter of the limiting post 544 is smaller than the diameters of the cutter plate hole 518 and the lock shaft plate hole 524, ensuring that the limiting post 544 can be smoothly inserted into the cutter plate hole 518 and the lock shaft plate hole 524, fixing the cutter part 51 and the fastening part 53 on the lock shaft part 52, and preventing the cutter part 51 and the fastening part 53 from falling off the lock shaft part 52.

[0055] Scales are engraved on the cutter plate 517. When the limiting post 544 extends into the corresponding cutter plate hole 518, the scale corresponding to the cutter plate hole 518 is the moving distance of the fastening part 53. Since the bottom edge of the cutter body 513 is inclined and the inclination angle is 60°, according to the side length calculation rule of a right triangle, the length of the cutter body 513 protruding from the fixed length wheel 511 can be calculated based on the moving distance of the fastening part 53. The circumference of the circular trajectory formed by adding this length to the radius of the fixed length wheel 511 is the length of the cut metal wire.

[0056] Since the knob 62 is rotatably connected to the baffle 61, the screw 63 is fixedly connected to the pressure regulating 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. The screw 63 drives the pressure regulating shaft 64 to slide up and down in the guide groove 32, thereby adjusting the distance between the wire feeding pressure wheel 7 and the fixed length wheel part 5. Rotate the knob 62 to move the screw 63 upward, increasing the distance between the wire feeding pressure wheel 7 and the fixed length wheel part 5, which is convenient for the wire to pass through. Pull out the wire on the wire feeding wheel 2, insert one end of the wire into the left wire feeding pipe 15, pass it between the wire feeding pressure wheel 7 and the fixed length wheel part 5, and finally insert it into the right wire feeding pipe 16; rotate the knob 62 in the reverse direction to drive the screw 63 to move downward. The screw 63 pushes the wire feeding pressure wheel 7 downward through the pressure regulating shaft 64 and presses it against the outer ring of the fixed length wheel 511, clamping the wire between the two. Start the servo motor 31, and the servo motor 31 drives the locking shaft body 521 to rotate. The locking shaft body 521 drives the fixed length wheel 511 to rotate through the fastening ring 531. The fixed length wheel 511 drives the wire feeding pressure wheel 7 to rotate together through friction, pushing the wire forward along the right wire feeding pipe 16. When the cutter body 513 follows the fixed length wheel 511 to rotate to the tangent point of the wire feeding pressure wheel 7 and the fixed length wheel 511, under the pressure of the wire feeding pressure wheel 7, the cutter body 513 cuts the wire. Since the height of the cutter body 513 protruding from the fixed length wheel 511 remains unchanged, the lengths of the cut wires are equal, all equal to the circumference of the outer edge track of the cutter body 513; after the wire is cut, the servo motor 31 pauses working. Rotate the knob 62 to lift the wire feeding pressure wheel 7, pull the wire on the left side, pass it between the wire feeding pressure wheel 7 and the fixed length wheel 511, and extend it into the right wire feeding pipe 16. Then press the wire feeding pressure wheel 7 on the fixed length wheel 511, and the servo motor 31 works again, continuing to push the wire in the left wire feeding pipe 15 to the right wire feeding pipe 16 and pushing the previously cut wire in the right wire feeding pipe 16 forward. In this way, the wire feeding of the wire is completed in a cycle.

[0057] When it is necessary to change the length of the wire to be cut, rotate the threaded sleeve 543 to move it downward along the threaded rod 542, pull out the limit post 544 from the cutter plate hole 518 and the lock shaft plate hole 524, so that the limit post 544 loses its restriction on the cutter plate 517 and the lock shaft plate 523. Pinch the rotating handle part 55 and pull it outward to pull the fastening part 53 out of the cutter part 51. The fastening ring 531 no longer supports the cutter body 513 upward. The spring 516 rebounds, and the cutter body 513 is pushed by the slider 515 and slides into the fixed-length wheel 511. The top surface of the cutter body 513 is lower than the outer surface of the fixed-length wheel 511, preventing accidental injury by the cutter body 513 when replacing the cutter part 51. After the fastening part 53 is pulled out, remove the cutter part 51 from the lock shaft part 52, replace the fixed-length wheel 511 with a suitable radius, put the new fixed-length wheel 511 on the lock shaft part 52, and then insert the fastening part 53 into the gap between the cutter part 51 and the lock shaft part 52, so that the outer guide bar 532 is located in the cutter guide groove 512, the inner guide bar 533 is located in the lock shaft guide groove 522, and the cutter plate 517 is located directly above the lock shaft plate 523. At the same time, the limit post 544 is located directly below the cutter plate 517 and the lock shaft plate 523. Push the fastening part 53 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 advances, it pushes the cutter body 513 upward, pushing the cutter body 513 out of the fixed-length wheel 511, which is convenient for cutting the wire. Then rotate the threaded sleeve 543 to push the limit post 544 into the lock shaft plate hole 524 and the cutter plate hole 518 in sequence, fixing the cutter part 51 and the fastening part 53 on the lock shaft part 52 to prevent the cutter part 51 and the fastening part 53 from being thrown out when the servo motor 31 drives the lock shaft part 52 to rotate. If the radius of the replaced fixed-length wheel 511 is smaller, it is necessary to move the wire supply pressure wheel 7 downward to press the wire on the fixed-length wheel 511. If the radius of the replaced fixed-length wheel 511 is larger, it is necessary to move the wire supply pressure wheel 7 upward to press the wire on the fixed-length wheel 511. If the length of the wire is to be finely adjusted, there is no need to replace the cutter part 51. When the fastening part 53 is pulled out from between the cutter part 51 and the lock shaft part 52, the cutter body 513 moves downward under the action of the spring 516, and the length protruding from the fixed-length wheel 511 decreases, and its trajectory circumference decreases, and the length of the cut wire decreases accordingly. When the fastening part 53 is pushed inward between the cutter part 51 and the lock shaft part 52, the fastening ring 531 pushes the cutter body 513 to move upward under the spring 516, and the length protruding from the fixed-length wheel 511 increases, and its trajectory circumference increases, and the length of the cut wire also increases accordingly. After adjusting the position of the fastening part 53, insert the limit post 544 into the corresponding cutter plate hole 518 and lock shaft plate hole 524. The scale on the cutter plate 517 shows the length of the cutter body 513 protruding, and thus the length of the cut wire can be determined. Through this precisely controlled method, the amount of the coated 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 further improving the quality of the subsequent coated products.

The evaporation coating system includes a pulsating wire feeding assembly and an evaporation tank. A plurality of evaporation boats and an electrode assembly for supplying power to the evaporation boats are arranged in the evaporation tank; the pulsating wire feeding assembly includes the pulsating wire feeding mechanism as described above.
