step one, the chip board is fixed in a chip groove (21) on the cutting table (2), the motor (4) drives the rotating disc (3) to rotate, and then drives the driving belt (8) to move, and the cutting blade (7) cuts the chip board when passing through the upper part of the chip board.
Step two, the transmission diameter of the rotating disc (3) is changed once along with each rotation of the transmission belt (8) so as to change the position of the transmission belt (8) relative to the cutting table (2), thereby changing the cutting position of the chip plate and achieving the aim of continuously cutting the chip plate for a plurality of times.
Step three, the transmission diameter adjusting method of the rotating disc (3) in the step two: the driving motor (4) drives the gear (42) and the convex disc (41) to rotate simultaneously, the gear (42) drives the rotating disc (3) to rotate when rotating, when the side surface of the convex disc (41) is in normal contact with the roller (51), the clamping teeth (52) are separated from the chuck (310), the lifting disc (311) is in a descending state, the clamping ring (3112) is inserted into the clamping groove (3101), the lifting disc (311) is connected to the chuck (310), the adjusting disc (31) is stably connected with the rotating disc (3), and the rotating disc (3) can stably drive the adjusting disc (31) to rotate together when rotating, so that the position stability of the supporting plate (33) is ensured, and the position stability of the driving belt (8) is further ensured. After the cutting blade (7) rotates for one circle, the roller (51) rolls into the notch groove (43) on the convex disc (41), the rotating frame (5) rotates to drive the lifting disc (311) to ascend, the clamping ring (3112) is separated from the clamping groove (3101), the clamping teeth (52) are clamped on the side face of the clamping disc (310), the clamping teeth (52) are fixed on the clamping disc (310), and the adjusting disc (31) is limited by the clamping teeth (52) and can not rotate, so that the sliding shaft (36) is driven to slide in the arc-shaped hole (35) when the rotating disc (3) continues to rotate to drive the supporting plate (33) to move, the transmission diameter of the rotating disc (3) is changed, and the cutting position of the cutting blade (7) is changed; after the roller (51) rolls out of the notch groove (43), the rotating discs (3) of the adjusting disc (31) are connected again stably, and the two continue to rotate together.
