Slitting processing device

The utility model provides a slitting processing device, which relates to the technical field of slitting processing devices and comprises sleeve plates, a first rolling shaft is rotatably connected between the sleeve plates, extension plates are slidably connected to the inner sides of the sleeve plates, and a second rolling shaft is rotatably connected between the extension plates. Through the arrangement of the sleeve plate, the first rolling shaft, the extension plate, the second rolling shaft, the single-shaft air cylinder, the rolling wheel, the elastic strip, the first gear, the second gear and the motor, the position adjusting function of the extension plate can be achieved through the structural combination of the sleeve plate, the first rolling shaft, the extension plate, the second rolling shaft and the single-shaft air cylinder, and therefore the height of the second rolling shaft is adjusted; the stability of conveying work is improved in a clamping mode, the height adjustment of an extension pla
