The driving device is connected to the knife holder 9 and drives the knife holder 9 to reciprocate along the guide mechanism. The knife holder 9 is provided with a cutting blade 10.

[0024] The guiding mechanism is arranged parallel to the conveyor belt 15, and there is no intersection on its extension line, which ensures that the cutter 10 can cut the sample on the conveyor belt 15 without damaging the conveyor belt 15.

[0025] The frame 1 is a gantry structure, including: crossbeams and columns. The crossbeams are installed on two columns to form the gantry structure.

[0026] The frame 1 is also equipped with a mounting plate 14 with a long hole, through which the cutter 10 can move back and forth.

The slider 8 in the linear guide rail 5 mechanism is slidably installed on the linear guide rail 5. The tool holder 9 is fixed on the slider 8.

[0028] The guiding mechanism can also be a guide light bar mechanism. The light bar in the guide light bar mechanism is installed on two columns of the frame 1. The slider 8 in the guide light bar mechanism is slidably fitted on the light bar. The tool holder 9 is fixed on the slider 8.

[0029] The driving device is a transmission type driving device and a telescopic driving device, wherein the transmission type driving device is a chain wheel transmission type driving device or a gear and rack driving device.

[0030] Proximity switches are installed at both ends of the linear guide 5 or the light lever in the guide mechanism, and the cutting is stopped when the slider 8 moves to the position of the proximity switch.

[0031] The chain wheel transmission type driving device is taken as an example in the embodiment, which comprises a driving chain wheel 11, a driven chain wheel 7, a chain 6, the driving chain wheel 11, and a motor 12. The driving chain wheel 11 and the driven chain wheel 7 are respectively installed on the rack 1.
