A second gear 211 is installed on the side of the second synchronous belt 210 away from the third non-standard tooth 209. A turntable 212 is provided on one side of the second gear 211. A first connecting rod 213 is installed on the side of the turntable 212 away from the second gear 211. A second connecting rod 214 is installed at the bottom of the first connecting rod 213. The bracket 1 is connected to the rotating roller 201 via a shaft. The bracket 1 is connected to the rack 205 via a shaft. The bracket 1 is slidably connected to the conveyor rod 206.

During operation, the first servo motor 207 drives the rotating roller 201 to convey the steel bar to the bottom of the cutting head 5. The first servo motor 207 reverses to make the steel bar contact the raised mounting base 301. The second profile tooth 208 drives the third profile tooth 209 to move intermittently, thereby driving the cutting head 5 to cut the steel bar. After the mounting base 301 falls, the first profile tooth 204 drives the rack 205 to rise, placing the steel bar outside the bracket 1. This realizes that the device has the function of facilitating the conveying and cutting of steel bars.

[0033] Furthermore, such as Figure 1 and Figure 3As shown, the adjustment structure 3 includes a mounting base 301, a second servo motor 302, a bidirectional lead screw 303, an internal thread block 304, a third connecting rod 305, a connecting block 306, a baffle 307, and a pin 308. The mounting base 301 is installed in the middle of the bracket 1. The second servo motor 302 is installed on one side of the mounting base 301. The bidirectional lead screw 303 is installed on one side of the second servo motor 302. The external wall of the bidirectional lead screw 303 is equipped with internal thread blocks 304. The third connecting rod 305 is installed on both sides of the internal thread block 304. The connecting block 306 is installed on the top of the third connecting rod 305. The baffle 307 is welded to the top of the connecting block 306. The pin 308 passes through the bottom of the mounting base 301. During operation, the pin 308 is placed outside the second servo motor 302, and the sliding mounting base 301 is adjusted to the desired position. The pin 308 has the function of fixing the position of the mounting base 301. The second servo motor 302 drives the baffle 307 to rise and fall inside the mounting base 301, thus enabling the device to easily adjust the length of the cutting steel bars.

[0034] Working principle: Place the pin 308 outside the mounting base 301, push the mounting base 301 to slide it inside the bracket 1, adjust it to the desired position, insert the pin 308 through the mounting base 301 and the bracket 1, place the steel bar at the top of the rotating roller 201, start the first servo motor 207, the first servo motor 207 drives a set of rotating rollers 201 and the second irregular tooth 208 to rotate, the second irregular tooth 208 drives the first gear 202 and the first irregular tooth 204 to rotate through the first synchronous belt 203. The first gear 202 drives the other five sets of rotating rollers 201 to rotate synchronously via the first synchronous belt 203, thereby conveying the steel bars to the bottom of the cutting head 5. This activates the second servo motor 302, which drives the bidirectional lead screw 303 to rotate inside the mounting base 301. The bidirectional lead screw 303 drives two sets of internal threaded blocks 304 to move closer together, which, through the third connecting rod 305 and connecting block 306, causes the baffle 307 to slide inside the mounting base 301. This causes the baffle 307 to rise, reversing the first servo motor 207. The first end of the reinforcing bar comes into contact with the first servo motor 207, while the second irregular tooth 208 drives the third irregular tooth 209 to rotate intermittently. The third irregular tooth 209 drives the second gear 211 to rotate via the second synchronous belt 210. The second gear 211 drives the turntable 212 to rotate. The turntable 212 drives the second connecting rod 214 to slide up and down inside the machine body 6 via the first connecting rod 213. The second connecting rod 214 drives the cutting head 5 to move downward, starting the machine body 6 and cutting the uneven reinforcing bar with the cutting head 5. The second connecting rod 214 then drives it to rise, reverses the second servo motor 302, and drives the baffle 307 to fall. The steel bar is transported to the side away from the cutting head 5. The first special tooth 204 drives the rack 205 to move intermittently. The rack 205 drives the conveyor rod 206 to rise on the top of the support 1. The top of the conveyor rod 206 is sloping, pushing the cut steel bar to the outside of the support 1. The electric push rod 4 is activated, and the cut steel bar waste and residue are pushed to the outside of the support 1. Thus, the simultaneous processing of multiple steel bars is completed.
