The feeding mechanism 2 is arranged at the front end of the machine 1, and a feeding port 21 for feeding is provided on the top thereof, and a cutting chamber 22 is provided on the bottom thereof. The feeding port 21 and the cutting chamber 22 are connected by an inclined slide, so that the bamboo material that has been preliminarily cut can enter from the feeding port 21 and then slide into the cutting chamber 22 by gravity. A roller 23 and a rotating roller 24 are provided in the cutting chamber 22. The sliding mechanism 3 is arranged on the end face of the machine, and includes a sliding platform 31 and a driving device.

The plurality of slitting blades 52 are detachably connected to the rotating shaft 51, and the spacing between the plurality of slitting blades 52 can be flexibly adjusted. The output end of the first motor 53 is connected to the rotating shaft 51, and is used to drive the rotating shaft 51 to rotate and drive the slitting blades 52 to rotate to slitting the sheet veneer. By adjusting the number and spacing of the slitting blades 52, strips of veneer of different widths can be cut out, thereby meeting the different usage requirements of users. The sliding platform 31 is provided with a slag drop hole 33 below the slitting mechanism 5, so that the debris generated during slitting can fall through the slag drop hole 33.
