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

[0021] The guide mechanism is arranged vertically and parallelly to the conveyor belt 15 , and there is no intersection on the extension line thereof, so as to ensure that the cutting knife 10 can cut the sample on the conveyor belt 15 without damaging the conveyor belt 15 .

[0022] The frame 1 is a gantry structure, including a crossbeam and columns, wherein the crossbeam is installed on two columns to form the gantry structure.

[0023] The frame 1 is also provided with a mounting plate 14 with an elongated hole, and the cutting knife 10 penetrates the elongated hole and can move back and forth.

[0024] The guiding mechanism is a linear guide rail 5 mechanism, in which the linear guide rail 5 is installed on two columns of the frame 1 , the slider 8 in the linear guide rail 5 mechanism is slidably installed on the linear guide rail 5 , and the tool holder 9 is fixed on the slider 8 .

[0026] The driving device is a transmission driving device and a telescopic driving device, wherein the transmission driving device is a sprocket transmission driving device or a gear rack driving device.

[0027] In the guide mechanism, proximity switches are installed at both ends of the linear guide rail 5 or the optical bar, and the cutting is stopped when the slider 8 moves to the proximity switch position.

[0028] This embodiment takes a sprocket drive device as an example, comprising: a driving sprocket 11, a driven sprocket 7, a chain 6, a driving sprocket 11, and a motor 12.
