When adjusting the distance between the knife discs on the knife rollers, only the knife rollers need to be switched. The rotation of motor b on the slide plate drives the rotating shaft a to rotate slowly, thereby driving the plugged knife rollers to rotate. When the rotation continues, the infrared sensor on the inner side of the frame b continuously emits infrared rays inward, and the emitted infrared rays are directly projected onto the positioning plate installed on the knife roller. The positioning plate is provided with positioning holes corresponding to the cross-shaped jack positions of the knife rollers. When the infrared rays emitted by the infrared sensor are directly After shooting into the positioning hole, the hydraulic cylinder on the bracket shortens and drives the connected skateboard to move right.

After separation, the motor a on the frame a rotates, and the rotation of the motor a drives the rotating plate b connected to the rotating shaft to rotate. The rotating plate b rotates 120 degrees to drive the lower knife roller to rotate upward, thereby switching the knife roller and transferring the knife discs with different spacings to the upper part. After switching, the hydraulic cylinder extends and pushes the connected skateboard to move left. The left movement of the skateboard drives the rotating shaft a connected to the motor b to move left and insert into the socket opened on the knife roller. The rotation of the motor b can drive the knife roller connected to the rotating shaft a to rotate to shear the steel coil.

The brush rack and the dust suction pipe can be used to remove dust from the sheared steel coils; horizontal racks are installed on the inner sides of the racks a and b, and the horizontal racks are located on both sides of the steel coils. After being sheared by the knife disc, the steel coils move backwards and enter between the two horizontal racks. Brush racks are installed on the horizontal racks, and the bristles on the brush racks can continuously brush the surface of the steel coils, so that the sheared debris and dust on the surface of the steel coils can be separated from the steel coils. A dust suction pipe is installed on the horizontal rack, and the dust suction pipe is interconnected with the filter box. The exhaust fan in the filter box can continuously extract the air from the top, that is, the suction head at the bottom of the dust suction pipe generates suction, which can extract air from the upper and lower surfaces of the steel coils. The debris, dust, etc. brushed by the brush rack enter the filter box with the air, and are intercepted and filtered by the filter cloth in the filter box, so that the surface of the steel coils can be continuously dusted.
