[0022] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0023] Reference Figure 1 As shown, this utility model provides a technical solution: a continuous cutting device for welding wire processing, comprising: a base 1, a guiding component 2 provided at the upper end of the base 1, a feeding component 3 provided on one side of the base 1, a stretching component 4 provided at the upper end of the base 1, a moving component 5 provided at one end of the stretching component 4, the moving component 5 being located at the upper end of the base 1, a cutting component 6 provided at the upper end of the moving component 5, a pressing component 7 provided at the upper end of the moving component 5, and a collecting box 8 provided on one side of the base 1;

[0024] The material guiding component 2 includes a worktable 21 disposed on the upper end of the base 1. A groove is formed at the upper end of the worktable 21, and a guide plate 22 is disposed at the upper end of the groove. A slit 221 is formed on the outer surface of the guide plate 22. An opening slot 23 is formed on one side of the guide plate 22, and a spring is fixed to one side of the opening slot 23. A stop block 26 is fixed to one end of the spring. A locking strip 25 is rotatably disposed on one side of the stop block 26. A blocking post 24 is fixed to one side of the guide plate 22, and the locking strip 25 engages with the blocking post 24. The interior of the groove is... The worktable 21 has a sliding groove 27, a through groove and a bolt 29 on its outer surface, and a threaded hole at one end of the stop block 26. The sliding groove 27 is connected to the through groove, and one end of the bolt 29 passes through the through groove and the sliding groove 27 and is threadedly connected to the stop block 26. When processing the welding wire, the snap-fit ​​strip 25 is first fixed to the blocking post 24, and then the stop block 26 is pulled into the opening groove 23 of the guide plate 22 by the spring. The guide plate 22 is then placed in the groove of the worktable 21, adjusted to a suitable position, and a suitable number of guide plates 22 are placed. This allows each guide plate 22 to carry one welding wire, improving cutting efficiency. The snap-fit ​​strip 25 is removed from the blocking post 24. A spring moves the stop block 26 into the groove 27, and the bolt 29 is then used to fix the stop block 26 through the groove 27. This fixes the guide plate 22 within the groove of the worktable 21. The welding wire is pulled from the guide component 2 to the feeding component 3, and then pulled from the feeding component 3 onto the guide plate 22. The welding wire has the same inner diameter as the guide plate 22. The guide component 2 is then activated. The feeding component 3 causes the welding wire to move forward along the direction of the guide plate 22, so that the welding wire will not bend during the movement. There are 11 sets of cuts 221 on the guide plate 22. The depth of the cuts 221 is consistent with the inner groove of the guide plate 22, so that the welding wire can be completely cut off. The distance between each set of cuts 221 is 5mm. With the cuts 211 with a preset fixed spacing, there is no need to remeasure and mark the cutting position each time. The cutting component 6 can quickly position and cut, improving the cutting efficiency.

[0025] The upper end of the base 1 is provided with a T-shaped groove 11, and the lower end of the worktable 21 is fixed with a T-shaped block 28. The worktable 21 is slidably connected to the T-shaped groove 11 through the T-shaped block 28. When multiple welding wires need to be cut, the worktable 21 is pulled out from the T-shaped groove 11, and then the guide plate 22 is placed in the worktable 21 for easy operation.

[0026] The feeding component 3 includes a support rod 32 disposed on one side of the base 1. Two sets of support rods 32 are provided, with a rotating shaft between the two sets. A motor A31 is disposed on one side of one set of support rods 32. The output end of motor A31 passes through the support rod 32 and is fixedly connected to the rotating shaft. A welding wire coil 33 is sleeved on the outer surface of the rotating shaft. The stretching component 4 includes a support column A44 and a support column B45 disposed on the upper end of the base 1. A drive roller 42 and a driven roller 43 are rotatably disposed on one side of support column A44. A motor B41 is disposed on one side of support column B45. The output end of motor B41 passes through support column B45 and is fixedly connected to one end of the drive roller 42. One end of the driven roller 43 passes through support column B45 and extends to the support column B45. On one side, gears are fitted on the outer surfaces of the driving roller 42 and the driven roller 43. The two sets of gears mesh with each other. The welding wire coil 33 is fitted onto the rotating shaft, and one end of the welding wire coil 33 is passed between the driving roller 42 and the driven roller 43. Motors A31 and B41 are turned on. Motor A31 drives the welding wire coil 33 to rotate, and motor B41 drives the driving roller 42. Since motors A31 and B41 are of the same model, the rotation speed of the welding wire coil 33 driven by motor A31 matches the speed at which the welding wire is moved by motor B41 driven by the driving roller 42. The driving roller 42 moves the welding wire through friction and applies tension to the welding wire. Through gear meshing, synchronous reverse rotation is achieved to drive the driven roller 43. The two rollers clamp the welding wire and provide tension, thereby stretching the welding wire.

[0027] The moving component 5 includes a support column C52 mounted on the upper end of the base 1. A motor C51 is mounted on one side of the support column C52, and a threaded rod A53 and a fixed rod A54 are mounted on the other side. One end of the fixed rod A54 is fixedly connected to the support column C52, and the other end is fixedly connected to the support column A54. The output end of the motor C51 passes through the support column C52 and is fixedly connected to one end of the threaded rod A53. The other end of the threaded rod A53 is rotatably connected to the support column C52. A telescopic column 55 is fitted onto the outer surfaces of the threaded rod A53 and the fixed rod A54. The telescopic column 55 is threadedly connected to the threaded rod A53 and slidably connected to the fixed rod A54. When the motor C51 is turned on, the motor C51 drives the threaded rod A53, which in turn moves the telescopic column 55, enabling rapid switching between different cutting lengths and improving production efficiency.

[0028] The cutting component 6 includes an open column 62 located at the upper end of the telescopic column 55. A threaded rod B63 and a fixed rod B64 are disposed inside the open column 62. A motor D61 is mounted on one side of the open column 62. The output end of the motor D61 passes through the open column 62 and is fixedly connected to one end of the threaded rod B63. The other end of the threaded rod B63 is rotatably connected to the inner wall of the open column 62. Both ends of the fixed rod B64 are fixedly connected to the inner wall of the open column 62. A slider 65 is fitted onto the outer surface of the threaded rod B63 and the fixed rod B64. The slider 65 is threadedly connected to the threaded rod B63 and slidably connected to the fixed rod B64. An electric push rod A66 is fixed to the lower end of the slider 65. A... When the guillotine 67 is turned on, the motor D61 drives the threaded rod B63, which in turn moves the slider 65. The guillotine 67 then moves back and forth along the threaded rod B63. Driven by the electric push rod A66, the guillotine 67 moves downwards to cut the welding wire. The shape of the cut 221 matches the shape of the guillotine 67's cutting edge. Photoelectric sensors are installed on one side of the guillotine 67 and diagonally above the cut 221. When the guillotine 67 moves close to the cut 221, the photoelectric sensor detects its position and transmits a signal to the control system. The control system precisely controls the falling position of the guillotine 67 based on the photoelectric sensor signal, ensuring that the guillotine 67 accurately lands on the cut 221.

[0029] The extrusion component 7 includes a grooved column 71 located on the upper end of the support column C52. An electric push rod B72 is fixed to the inner wall of the grooved column 71. A fixing plate 73 is fixed to the lower end of the electric push rod B72. An extrusion block 74 is fixed to the lower end of the fixing plate 73. The extrusion block 74 corresponds to the slot of the guide plate 22. The opening of the collection box 8 corresponds to the discharge position of the guide plate 22. The distance between the cut 221 on the side near the collection box 8 and the extrusion block 74 is 10mm. A sensor is installed at the lower end of the extrusion block 74. When the welding wire passes under the extrusion block 74, the sensor detects the position of the welding wire and transmits a signal to the electric push rod B72, causing the electric push rod B72 to push the extrusion block 74 to press the welding wire. The position of the extruded welding wire is fixed each time, so as to ensure the accuracy of the cutting length during cutting. After cutting, the electric push rod B72 drives the extrusion block 74 to move upward. The uncut welding wire pushes the cut welding wire forward and falls into the collection box 8.

[0030] Working principle: First, pull the worktable 21 out of the T-slot 11. Then, place the guide plate 22 in the groove of the worktable 21, adjust it to the appropriate position, and place the appropriate number of guide plates 22. Next, remove the snap-fit ​​strip 25 from the stop post 24. The spring moves the stop block 26 into the slide groove 27. Then, fix the stop block 26 through the slide groove 27 with the bolt 29, thereby fixing the guide plate 22 in the groove of the worktable 21. Push the worktable 21 so that the T-block 28 is in contact with the T-slot 11. The sliding connection fixes the worktable 21 to the base 1. The welding wire is pulled out from the rotating shaft, passes between the driving roller 42 and the driven roller 43, and finally stretches onto the guide plate 22. Motors A31 and B41 are turned on, causing the welding wire to move forward along the direction of the guide plate 22. When the welding wire passes under the extrusion block 74, the sensor at the lower end of the extrusion block 74 senses the position of the welding wire and transmits the signal to the control system. The control system determines the position of the welding wire based on the signal and controls the electric push rod B72. Push the extrusion block 74 to press down the welding wire, and the welding wire transmission stops. At this time, turn on the motor C51. The motor C51 drives the threaded rod A53, which in turn moves the telescopic column 55. The telescopic column 55 moves the guillotine 67 in the direction of the threaded rod A53 until it reaches the required cutting length and stops. Then turn on the motor D61, which drives the threaded rod B63. The threaded rod B63 moves the slider 65, and the guillotine 67 can then move back and forth along the direction of the threaded rod B63 to cut the notch 22. 1. Center alignment: When the photoelectric sensor at the cut 221 detects the position of the guillotine 67, it transmits a signal to the control system. The control system uses the signal from the photoelectric sensor to precisely control the electric push rod A66 to push the guillotine 67 to its falling position, ensuring that the guillotine 67 falls on the cut 221. After shearing is completed, the motors A31 and B41 are turned on again. The electric push rod B72 drives the extrusion block 74 to move upward, causing the uncut welding wire to push the cut welding wire forward and fall into the collection box 8.

[0031] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
