At the same time, when the cutting knife 334 contacts the knife gate seat 44, the friction heat between the cutting knife 334 and the knife gate seat 44 can be reduced. A conveyor 2 is arranged at the top of the machine 1 near the front side. The conveyor 2 is a prior art, and is mainly composed of a frame, a conveyor belt, a drive motor, a drive shaft and other structures, and is used to transport materials. A plurality of legs 11 are arranged at the bottom of the machine 1 near the edge.

[0028] Figure 1-Figure 4The second embodiment is shown, which is mainly different from the first embodiment in that the cutting mechanism 3 includes: a motion component 31, which is arranged on the top of the machine 1, and the motion component 31 includes an eccentric wheel 311 fixedly mounted on both ends of the transmission shaft of the conveyor 2, and the end surface of the eccentric wheel 311 is rotatably provided with a connecting rod 312, and the motion component 31 also includes two fixed seats 313 fixedly mounted on the top of the machine 1, and the outer surface of the fixed seat 313 is fixedly mounted with a guide sleeve 314, and a slide rod 315 is movably provided in the inner hole of the guide sleeve 314, and the bottom end of the slide rod 315 is fixed The rotating seat 316 is fixedly connected, and the rotating seat 316 is rotatably connected to the connecting rod 312 through a bearing. The top of the sliding rod 315 is fixedly installed with a support rod 317. The adjustment component 32 is arranged on the top of the machine 1. The cutting component 33 is arranged on the top of the machine 1. The adjustment component 32 includes a fixed plate 321 fixedly installed between the two support rods 317.
