The shearing machine 20 is a conventional equipment known to the public in the prior art, so its specific working principle is not described in detail. The shearing machine 20 and the shearing knife seat 19 cooperate with each other to shear the steel strip. The processing table 1 is internally rotatably connected with a conveying roller 21, and the steel strip is conveyed by the conveying roller 21.

[0024] In this embodiment, a grinding mechanism is provided on the outside of the processing table 1, and the grinding mechanism includes a mounting shell 2 movably connected to the top of the processing table 1, a servo motor 3 is fixedly installed on the outside of the mounting shell 2, a threaded shaft 4 is fixedly connected to the output shaft of the servo motor 3, and the end of the threaded shaft 4 away from the servo motor 3 is rotatably connected to the mounting shell 2, an adjusting sleeve 5 is threadedly connected to the outside of the threaded shaft 4, a limiting slider 12 is fixedly connected to the top of the adjusting sleeve 5, a limiting slot is provided inside the mounting shell 2, and the limiting slider 12 is slidably connected to the inside of the limiting slot. Since the adjusting sleeve 5 is limited by the limiting slider 12, the adjusting sleeve 5 is laterally moved and adjusted when the threaded shaft 4 rotates.

[0025] It should be noted that a first electric push rod 6 is fixedly installed at the bottom of the adjusting sleeve 5, a driving motor 7 is fixedly installed on the output end of the first electric push rod 6, and a grinding disc 8 is fixedly connected to the output shaft of the driving motor 7. The first electric push rod 6 is started to make the grinding disc 8 close to the steel belt, and the driving motor 7 is started to drive the grinding disc 9 to rotate, so that the grinding disc 9 grinds the steel belt. At the same time, the grinding disc 9 is driven to move by the adjusting sleeve 5 to cover and grind the welding position, thereby improving the quality of welding.

[0026] In this embodiment, a first hydraulic push rod 15 is fixedly installed on the inner top wall of the mounting shell 2, a flash butt welding machine 16 is fixedly installed on the output end of the first hydraulic push rod 15, a second hydraulic push rod 17 is fixedly installed on the inner top wall of the mounting shell 2, a pressure plate 18 is fixedly connected to the output end of the second hydraulic push rod 17, the pressure plate 19 is fixed to the steel strip by starting the second hydraulic push rod 17, and then, the first hydraulic push rod 15 is started to enable the flash butt welding machine 16 to weld the two sections of steel strips.

One end of the dust suction pipe 10 away from the dust collector 9 extends to the inside of the processing table 1. A dust bag 11 is fixedly connected to the air outlet end of the dust collector 9. By starting the vacuum cleaner 9, suction is generated inside the dust suction pipe 10.

When the two sections of steel strips are close to each other, the second hydraulic push rod 17 is started to make the pressure plate 19 fix the steel strips, and the dust particles remaining in the air are absorbed by starting the vacuum cleaner 9. Then, the first hydraulic push rod 15 is started to make the flash butt welder 16 weld the two sections of steel strips. The second electric push rod 13 is started to move the grinding disc 9 to the welding position, and the driving motor 7 is started to make the grinding disc 9 grind the steel strip.
