Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] In order to solve the technical problems in the background technology, a sample preparation device for food safety detection is provided as follows:

[0019] Combination Figure 1-Figure 4As shown, a sample preparation device for food safety detection provided by the present invention includes a conveying structure 1 and a slitting structure 12. The conveying structure 1 includes a rectangular frame 3, a connecting shaft 5 is movably provided inside the rectangular frame 3, and a plurality of connecting shafts 5 are equidistantly distributed inside the rectangular frame 3. Both ends of the connecting shaft 5 are movably passed through the two sides of the rectangular frame 3, and a conveying wheel 4 is sleeved on the connecting shaft 5. A conveying belt 7 is sleeved on the conveying wheel 4. A motor 6 is provided on one side of the rectangular frame 3, and a power output end of the motor 6 is connected to one of the connecting shafts 5. In actual use, when the motor 6 rotates, it drives the connecting shaft 5 and the conveying wheel 4 to rotate synchronously, so that the conveying belt 7 sleeved on the conveying wheel 4 rotates together. Support legs are provided at both ends of the rectangular frame 3.
