[0042] Step 1: Connect the hydraulic cylinder to the inner cavity of the clamp block so that the hydraulic cylinder stands vertically in the inner cavity of the waste box, the waste box is pushed to the bottom of the machine body, and the waste box is located below the blade. After the cutting board is transported to a certain position on the carrier plate through one of the conveyor belts, the blade is pressed down to cut so that the edge of the cutting board can be cut flat, so that part of the waste directly falls into the inner cavity of the waste box through the gap between the carrier plate and another of the conveyor belts;

At the same time, the servo motor drives the rotating block to rotate, so that the pressing rod can change its position to press down the waste in the waste box cavity.

[0045] Technical effects and advantages of the present invention:

[0046] (1) The present invention utilizes a configuration in which a material guide mechanism and a driving mechanism cooperate with each other. Through the driving mechanism, the two material guide mechanisms can rotate in the same direction, so that the waste stuck on the side of the carrier plate can be pressed down and guided out, so that the waste can stably fall into the collecting mechanism for collection. At the same time, through the cooperation of the material pressing assembly and the hydraulic cylinder, the fluffy waste can be compacted in the inner cavity of the waste box, so that more debris waste can be collected, thereby improving the convenience of waste collection of the cutting machine and improving the cleaning efficiency of the waste.

[0047] (2) The present invention utilizes a setting mode in which a hydraulic cylinder and a material pressing assembly cooperate with each other. The hydraulic cylinder drives the material pressing assembly to move up and down in the inner cavity of the waste box, so that the pressing rod can compact the waste. At the same time, the downward inclined structure of the pressing rod can avoid concentrated accumulation of waste. The servo motor drives the pressing rod to rotate, so as to compact the waste accumulated in different parts of the inner cavity of the waste box, thereby avoiding the problem that the waste box cannot be loaded with more waste due to the fluffy waste. At the same time, the movement of the pressing rod in the inner cavity of the movable groove allows the debris that falls on the pressing rod to fall off when the pressing rod moves, thereby avoiding the phenomenon that the waste falls out of the waste box, thereby improving the stability of waste collection.
