[0033] Further, a detection rod 31 is slidably connected to the first detection chamber 3. A connecting block 33 is fixedly connected to the surface of the detection rod 31. A first spring 32 is fixedly connected to the surface of the connecting block 33.

When the arc of the wire reaches a certain degree, the detection mechanism 13 will send an alarm through the buzzer alarm 45 to remind the staff using the wire feeder 1.

[0035] Further, a pull rod 51 is slidably connected to the third detection bin 5. A limit plate 52 is fixedly connected to the surface of the pull rod 51. A third spring 53 is fixedly connected to the surface of the limit plate 52. A moving rod 54 is fixedly connected to the surface of the pull rod 51.

The third detection bin 5 can detect whether there is lubricating oil on the surface of the welding wire, and can clean the detection wheel 55 for detecting the lubricating oil, ensuring the detection requirements of the detection wheel 55 for the next detection, and improving the practicability of the use of the detection mechanism 13.

[0036] Further, circular holes are provided on the surfaces of the threaded tube 2, the detection tube 21 and the welding gun joint 22. The welding wire passes through the detection mechanism 13 through the circular holes of the threaded tube 2, the detection tube 21 and the welding gun joint 22. A guide tube can be first penetrated through the detection mechanism 13, then the welding wire is penetrated through the detection mechanism 13 through the guide tube, and then the guide tube is taken out, so that the welding wire can be penetrated through the detection mechanism 13, and the center holes are on a straight line. The detection tube 21 is transparent, facilitating viewing of the internal situation through the detection tube 21 and facilitating the detection link. The detection mechanism 13 is fixedly installed on the surface of the threaded joint 14 through the threaded tube 2. The threaded joint 14 is fixedly connected to one side of the wire feeder 1. The detection mechanism 13 is fixedly connected to one side of the wire feeder 1 through the threaded joint 14, facilitating the continued installation of the detection mechanism 13.

[0037] Further, a guide hole is provided on the surface of the detection tube 21. The detection rod 31 slides on the guide hole of the detection tube 21. One end of the first spring 32 away from the detection rod 31 is fixedly connected to the inner side of the detection tube 21. The elastic force of the first spring 32 acts on the detection rod 31 through the connecting block 33. Two groups of detection rods 31 are provided on the first detection bin 3. The connecting blocks 33 are also in two groups, and the connecting blocks 33 squeeze the welding wire on both sides of the welding wire. By feeling the detection rod 31 with fingers, when the welding wire is fed, it can be known whether the surface of the welding wire is smooth. A scale is provided on the surface of the detection rod 31. By observing the scales of the two groups of detection rods 31, the diameter of the welding wire can be known.

[0038] Further, the elastic force of the second spring 41 acts on the slider 42. A circular hole is formed on the surface of the slider 42. The slider 42 slides on the second detection chamber 4. The buzzer alarm 45 is fixedly connected to the outer surface of the detection tube 21. The button 43 controls the buzzer alarm 45 to emit an alarm through the connection wire 44. When the bending degree of the welding wire is very large, the welding wire will drive the slider 42 to slide on the second detection chamber 4 toward the button 43 through the circular hole of the slider 42 until the button 43 touches the button 43, so that the button 43 drives the buzzer alarm 45 to emit an alarm through the connection wire 44.

[0039] Further, a guiding hole is formed on the surface of the detection tube 21. The pull rod 51 slides on the guiding hole of the detection tube 21. The pull rod 51 drives the detection wheel 55 to horizontally move inside the third detection chamber 5 through the moving rod 54. One side of the third spring 53 away from the limiting plate 52 is fixedly connected to the inner side of the detection tube 21. A rectangular hole is formed on the surface of the detection tube 21. The detection wheel 55 and the rectangular hole are on the same straight line. One side of the detection wheel 55 away from the rectangular hole is attached to the welding wire. The detection wheel 55 will carry out the lubricating oil on the welding wire, which can be sensed by hand from one side of the rectangular hole of the detection tube 21. The first guiding rod 56 and the second guiding rod 57 are fixedly connected to the rectangular hole of the detection tube 21. The cleaning plate 58 is in a "T" shape. The cleaning plate 58 is slidably connected to the surface of the second guiding rod 57. The cleaning plate 58 is abutted and connected to one side of the detection wheel 55. When the cleaning plate 58 is on the first guiding rod 56, the cleaning plate 58 can be slid to fit on one side of the detection wheel 55. When the cleaning plate 58 is on the second guiding rod 57, the cleaning plate 58 can be temporarily stored to ensure that the detection wheel 55 can smoothly bring the lubricating oil to one side of the rectangular hole of the detection tube 21.

[0040] Further, the first rotating shaft 65 drives the first gear 66 and the second gear 67 to rotate at the same time. The second rotating shaft 68 drives the third gear 69, the fourth gear 610 and the wire feeding wheel 611 to rotate at the same time. The first rotating shaft 65 drives the first gear 66 and the second gear 67 to lift through the motor 64 and the first rotating shaft 65. Since the horizontal heights of the third gear 69, the fourth gear 610 and the wire feeding wheel 611 remain unchanged, when the first gear 66 and the second gear 67 are lifted, the horizontal heights of the first gear 66 and the second gear 67 will be changed, thereby changing the meshing relationship between the first gear 66, the second gear 67, the third gear 69 and the fourth gear 610.

[0041] Further, the diameter of the second gear 67 is the same as that of the fourth gear 610, and the diameter of the first gear 66 is the same as that of the second rotating shaft 68. The first gear 66 can mesh with the fourth gear 610, and the second gear 67 can mesh with the third gear 69. The distance between the first gear 66 and the second gear 67 is greater than the distance between the third gear 69 and the fourth gear 610, so that only one of the first gear 66, the second gear 67, the third gear 69, and the fourth gear 610 can maintain a meshing relationship. The first gear 66 drives the second rotating shaft 68 and the wire feeding wheel 611 to rotate through the fourth gear 610, and the second gear 67 drives the second rotating shaft 68 and the wire feeding wheel 611 to rotate through the third gear 69. By driving a large gear with a small gear, the force for the wire feeding wheel 611 to drive the welding wire is increased.

[0042] Working principle: First, pass a guide tube through the detection mechanism 13, then pass the welding wire through the detection mechanism 13 through the guide tube, and then take out the guide tube, so that the welding wire can pass through the detection mechanism 13. Connect the detection mechanism 13 to the threaded joint 14 through the threaded tube 2, so as to fix the detection mechanism 13 on the surface of the wire welding machine 1. Then fixedly install the welding torch on the welding torch joint 22. At this time, when the welding torch is blocked by wire, the cause of the wire blockage can be detected through the detection mechanism 13. Press two groups of detection rods 31 on the detection tube 21 at the same time, so that the two connecting blocks 33 are pressed against both sides of the welding wire. At this time, by observing the scales on the two detection rods 31, the diameter of the welding wire can be known. At the same time, when the welding wire moves, it will contact the connecting block 33. When the finger touches the detection rod 31, it can be felt through the first spring 32 whether the surface of the welding wire is smooth. When the bending of the welding wire is too large, the welding wire will drive the slider 42 to slide on the second detection chamber 4 and break free from the elastic force of the second spring 41, so that the slider 42 releases the button 43, and the button 43 makes the buzzer alarm 45 sound an alarm through the connecting wire 44 to remind the staff. When the bending of the welding wire is low, it can be seen through the detection tube 21 that after the slider 42 moves a certain distance, it will be pulled back by the elastic force of the second spring 41. The bending degree of the welding wire can be known through the moving amplitude of the slider 42. At the same time, when the welding wire moves, it will drive the lubricating oil on the surface to the detection wheel 55, and make the detection wheel 55 rotate on the moving rod 54. By pulling the moving rod 54 through the pull rod 51, the moving rod 54 can drive the detection wheel 55 to move to the rectangular hole on one side of the detection tube 21. Through the rectangular hole of the detection tube 21, it can be known whether there is lubricating oil on the surface of the detection wheel 55. Slide the cleaning plate 58 on the first guide rod 56, and the cleaning plate 58 can clean the lubricating oil on the detection wheel 55, which is convenient for the next detection.

[0043] The cylinder 63 drives the motor 64 to move up and down through the piston rod. The motor 64 drives the first gear 66 and the second gear 67 to move up and down through the first rotating shaft 65. During the up and down movement, the first gear 66 and the second gear 67 change their horizontal heights relative to the third gear 69 and the fourth gear 610, so that the first gear 66 can mesh with the fourth gear 610, and the second gear 67 can mesh with the third gear 69. The first gear 66 drives the second rotating shaft 68 and the wire feeding wheel 611 to rotate through the fourth gear 610, and the second gear 67 drives the second rotating shaft 68 and the wire feeding wheel 611 to rotate through the third gear 69. By using a small gear to drive a large gear, the force with which the wire feeding wheel 611 drives the welding wire is increased.
