[0036] In order to make the steel strip coil and the cut parts easy to separate and transport, such as Figure 1-2 and Figure 4 As shown, the conveying mechanism 1 includes a conveying platform 101, a plurality of conveying rollers 102 are rotatably installed inside the conveying platform 101, fixed plates 103 are fixedly installed on both sides of the discharge end of the conveying platform 101, support rollers 104 are rotatably installed on the inner sides of the two fixed plates 103 close to the conveying platform 101, and mounting grooves 105 are provided on the inner walls of the ends of the two fixed plates 103 away from the conveying platform 101, and first electric push rods 106 are fixedly installed on the inner walls of the ends of the two mounting grooves 105 close to the support rollers 104. The piston rods of the two first electric push rods 106 are fixedly installed with a movable seat 107, and a limiting roller 108 is rotatably installed between the two movable seats 107. The two first electric push rods 106 can drive the movable seat 107 to move along the inner wall of the adjacent installation groove 105, so as to adjust the distance between the limiting roller 108 and the supporting roller 104. The steel strip coil and the cut-off part can be supported and separated by the limiting roller 108, so that the steel strip coil and the cut-off part can be conveniently separated and transported.

[0037] In order to conveniently adjust the position of the cutting mechanism 3, as Figure 1-3 and Figure 5 As shown, the adjustment mechanism 2 includes two fixed frames 201, and the two fixed frames 201 are respectively fixedly installed at the two ends of the top of the conveying platform 101. The inner walls of the tops of the two fixed frames 201 are both provided with movable grooves 202.

At the same time, the movable groove 202 and the limiting rod 205 can limit the movement of the movable tooth plate 206, so that the movable tooth plate 206 remains stable during the movement. At the same time, the rotating shaft 303 is rotated by the second motor 304, so that the movable gear 305 is rotated. Through the meshing action between the movable gear 305 and the movable tooth plate 206, the movable frame 301 can move laterally along the movable tooth plate 206, and then the second electric push rod 308 is operated to make the mounting plate 309 move along the inner wall of the adjacent adjusting groove 307, so that the distance between the laser cutting head 310 and the steel strip coil can be adjusted, and then with the transportation of the steel strip coil and the adjustment of the lateral position of the laser cutting head 310, the laser cutting The head 310 can perform a cutting operation on the uneven edges on both sides of the steel strip coil. At the same time, the two first electric push rods 106 work so that the two movable seats 107 can move along the inner walls of the adjacent mounting grooves 105, and then the distance between the limiting roller 108 and the supporting roller 104 can be adjusted, so that the steel strip coil body can be conveyed from the top of the supporting roller 104 and the limiting roller 108, and the cut parts on both sides can bypass the top of the supporting roller 104 and then be conveyed from the bottom of the limiting roller 108, so that the steel strip coil body and the cut parts can be conveniently separated and conveyed, so that the device can conveniently cut the uneven parts on both sides of the rolled steel strip coil, so that the rolled steel strip coil can be kept regular, which can facilitate the subsequent rolling and use of the steel strip coil. This embodiment specifically solves the problem that the two sides of the rolled steel strip coil are prone to unevenness in the prior art, which will affect the subsequent rolling and use of the steel strip coil.
