[0019] The technical solutions of the present invention will be further described below in conjunction with the drawings and specific embodiments.

[0020] As shown in Figures 1 to 4As shown in the figure, in this embodiment, a wire feeding structure includes a wire outlet frame 1, a wire outlet module 2, and an upper wire collecting wheel 3. The upper wire collecting wheel 3 is located at the lower end of the wire outlet frame 1. A number of module mounting holes 4 are provided on the wire outlet frame 1. The wire outlet module 2 is fixed in the module mounting holes 4. A module mounting plate 5 is provided on the wire outlet module 2. A wire hanging cylinder shaft 6 rotates on the module mounting plate 5. A wire cylinder 7 is sleeved on the wire hanging cylinder shaft 6. A connecting plate 8 is fixed at the inner end of the wire hanging cylinder shaft 6. A thimble 9 is locked on the connecting plate 8. An emergency stop hole 21 is provided on the side of the wire cylinder 7. The end of the thimble 9 is inserted into the emergency stop hole 21. A locking nut 10 is installed at the outer end of the wire hanging cylinder shaft 6.

[0021] The wire cylinder 7 is wound with wire, which is wound and output from the lower upper wire collecting wheel 3. According to the usage requirements, there are six module mounting holes 4 in this embodiment. One wire outlet frame 1 can be provided at the upper and lower parts respectively to form up to twelve groups of wires for output. For the module mounting holes 4 that are not needed, just cover them with a cover plate directly. The module mounting plate 5, together with other components above, is assembled as a whole module on the module mounting holes 4. After the wire cylinder 7 is sleeved on the wire hanging cylinder shaft 6, the wire cylinder 7 is clamped tightly by the locking nut 10 on the outside. When the heavy wire cylinder 7 needs to stop rotating, the cylinder shaft motor 12 stops the wire hanging cylinder shaft 6 in time. The thimble 9 on the wire hanging cylinder shaft 6 is inserted into the emergency stop hole 21 to block and stop the wire cylinder 7.

[0022] Module locking holes 11 are provided on the edge of the module mounting plate 5. The wire outlet module 2 is locked on the module mounting holes 4 by screws on the module locking holes 11. According to the requirements, move the module mounting plate 5 close to the module mounting holes 4, align the module locking holes 11, and lock them with screws to complete the quick installation.

[0023] A cylinder shaft motor 12 is installed at the lower end of the module mounting plate 5. Cylinder shaft pulleys 13 are installed at the driving end of the cylinder shaft motor 12 and the end of the wire hanging cylinder shaft 6 respectively. A cylinder shaft belt 14 is connected between the cylinder shaft pulleys 13. The cylinder shaft motor 12 provides power. Through the transmission of the cylinder shaft pulleys 13 and the cylinder shaft belt 14, the wire hanging cylinder shaft 6 rotates, and the wire cylinder 7 on the wire hanging cylinder shaft 6 outputs wire.

[0024] An adjustment slot 15 is provided horizontally on the connecting plate 8. A connecting needle plate 16 is locked on the adjustment slot 15. The thimble 9 is locked on the connecting needle plate 16 by a nut. According to the size of the wire cylinder 7, the position of the connecting needle plate 16 can be adjusted from the adjustment slot 15. The thimble 9 on the connecting needle plate 16 can effectively press on the side arc surface of the wire cylinder 7.

[0025] A plurality of wire guiding auxiliary shafts 17 are arranged on the wire outlet frame 1. A front and rear wire main seat 18 is installed at the lower end of the wire outlet frame 1. A plurality of front and rear wire rotating shafts 19 are horizontally distributed on the front and rear wire main seat 18. The front and rear wire main shafts are fixed in the installation groove 20 of the front and rear wire main seat 18. The welding wire output from the wire reel 7 enters the lower front and rear wire rotating shafts 19 after passing around the wire guiding auxiliary shafts 17, and then bypasses the upper wire collecting wheel 3. The lower front and rear wire rotating shafts 19 can be adjusted left and right on the front and rear wire main seat 18 according to the position on the wire clamping structure.
