The vertical rod 12 is provided with two rotating shafts 16 through bearings, and the two rotating shafts 16 are respectively and correspondingly provided with a large belt wheel 17 and a small belt wheel 18; a belt 19 which is used for driving and connecting the large belt wheel 17 and the small belt wheel 18 is arranged between the large belt wheel and the small belt wheel; a sliding rod 18a which is horizontally matched with the matching groove 13a in a sliding manner is arranged at the eccentric position on the front end surface of the small belt wheel 18; the rotating shaft 16 corresponding to the large belt wheel 17 is also provided with a ratchet wheel 20, and the right side ratchet of the ratchet wheel 20 is abutted with the wedge-shaped block 14.

The circumference of the large pulley 17 is larger than the circumference of the small pulley 18.

Before use, the welding wire is fed on the backing table 4 in a constant-speed intermittent manner from left to right and passes through the cutting blade 11 in a stepwise manner.

When the swinging device is used, the motor 7 drives the auxiliary rocker 8 to rotate at a constant speed, so that the whole main rocker 6 can swing in a left-right reciprocating mode around the upper shaft 5.

When the main rocker 9 swings from right to left, the transmission rod 10 can be caused to slide to the upper side, and the ratchet 20 is stationary, thereby causing the cutting process of the welding wire to stop. This dwell process is primarily to facilitate the feed-right feeding of the welding wire.

When the main rocker 9 swings from left to right, the transmission rod 10 can be caused to slide downwards, the wedge block 14 can push the ratchet 20 to rotate anticlockwise when sliding downwards along with the transmission rod 10, the large belt wheel 17 synchronously rotates along with the ratchet 20 and performs differential transmission through the belt 19, so that the small belt wheel 18 can rotate at a constant speed for one circle, and under the matching action of the sliding rod 18a and the matching groove 13a, the knife handle 13 and the cutting knife 11 can perform reciprocating sliding up and down for one time, so that one-time cutting for a welding wire can be completed. The wire feed should be stopped during this cutting process.

Therefore, in conclusion, the welding wire cutting device can effectively control the cutting knife 11 to intermittently cut the welding wire by controlling the left-right swing of the main rocker 9, so that the welding wire can be cut in an equal division manner conveniently.
