However, some food pigments may harm human health, so in food safety, the chemical composition of pigments in food is generally tested; At present, a spectrometer is generally used to test the chemical composition of food pigments. During the test, a food sample is generally chopped up using a tool such as a knife, and then the chopped food sample is placed in a container, and water is placed in the container, so that the chopped food sample in the container is soaked with water to form a treatment liquid, and then the treatment liquid is taken out and added to a new container, and then a solvent and other reactants are added to the new container and shaken to form a reaction liquid in the new container, and then part of the reaction liquid in the new container is taken out and placed in a cuvette, and then the cuvette is placed in the detection hole on the spectrometer, and then the spectrometer is used for testing; However, manual shredding of food samples is prone to uneven sizes of shredded food samples, resulting in a high probability of insufficient food pigment content in the food samples immersed and extracted, which will affect the reaction quality of the pigment chemical components in subsequent food samples.

[0025] When in use, firstly, the circuit of the electromagnet 42 is turned on, so that the electromagnet 42 generates magnetism, then the iron plate 31 is pinched and the cuvette 3 is moved, and then the opening of the cuvette 3 is inserted into the positioning groove, so that the cuvette 3 is positioned and installed between the mounting plate 4, and the iron plate 31 is fitted with the lower end of the electromagnet 42. At this time, the magnetism of the electromagnet 42 will adsorb the iron plate 31, and then the installation operation of the cuvette 3 is completed. In the same way as the above steps, multiple cuvettes 3 are equidistantly installed on the lower end of the mounting plate 4; Then, food samples are put into the function box 6, and then the food samples are subjected to processing operations such as crushing, soaking, and reaction to generate reaction liquid, and then a certain amount of reaction liquid is transported to different cuvettes 3 through multiple quantitative boxes 7 and multiple sample delivery tubes 73, and then multiple cuvettes 3 are respectively inserted into different detection holes through the first electric push rod 8, the mounting plate 4 and other components, and then the reaction liquid in the cuvette 3 is tested by the spectrometer body 1; When the inspection is completed, the circuit of the electromagnet 42 is disconnected, thereby releasing the adsorption performance of the multiple iron plates 31, and then the first electric push rod 8 is used to make the mounting plate 4 and other components react upward to the original position. At this time, the multiple cuvettes 3 are still on the detection hole, and then the movable plate 2 is pushed to the right to expose the groove 11, and then the multiple cuvettes 3 are taken out, so that the cuvettes 3 can be easily disassembled and assembled, and the reaction liquid in the cuvettes 3 can be easily cleaned, which effectively ensures the subsequent normal inspection operations and the inspection effect.

[0026] Embodiment three: A first electric push rod 8 and other components are installed on the upper end of the movable plate 2 to pre-process the food sample, and the opening of the groove 11 is blocked by the movable plate 2, so that the movable plate 2 needs to move before and after the inspection. After the movable plate 2 moves to the right, most of the movable plate 2 will be located on the right side of the spectrometer body 1, but the components installed on the upper end of the movable plate 2 have weight, thereby exerting downward pressure on the movable plate 2, resulting in a high probability of deformation of the movable plate 2, resulting in a high probability of misalignment between the cuvette 3 and the corresponding detection hole on the bottom end of the groove 11, resulting in the cuvette 3 being unable to be normally inserted into the detection hole.

[0027] In order to solve the above problems, Figure 10-12 As shown, two support rods 23 arranged vertically and located on the right side of the telescopic rod 41 are hinged to the lower end of the movable plate 2 through elastic hinges. The support rods 23 provide a mounting carrier for the movable wheel 22 on the one hand, and lift the movable plate 2 on the other hand. The two movable wheels 22 are respectively arranged on the lower ends of the two support rods 23. The two movable wheels 22 cooperate to assist the movement of the movable plate 2. The connecting rod 232 is then arranged between the two support rods 23. The connecting rod 232 increases the mounting strength of the two support rods 23 on the one hand, and provides a mounting carrier for the magnetic strip 231 on the other hand. The magnetic strip 231 is embedded in the middle of the left end of the connecting rod 232, and the magnetic strip 231 is used for adsorption operation, and the iron sheet 201 located on the right side of the through slot 21 and used in conjunction with the magnetic strip 231 is embedded in the lower end of the movable plate 2, and the iron sheet 201 and the magnetic strip 231 are used in conjunction with each other to fold and store the supporting rod 23 and the movable wheel 22, and then the iron block 202 located on the left side of the magnetic strip 231 and used in conjunction with the magnetic strip 231 is set on the right end of the spectrometer body 1, and the iron block 202 and the magnetic strip 231 are used in conjunction with each other to stably install the movable plate 2; The front and rear walls of the groove 11 are both recessed outward to form a slide groove 203 which is arranged transversely and extends to the right end of the spectrometer body 1. Two transversely arranged slide bars 204 which are slidably connected to the two slide grooves 203 are respectively arranged on the front and rear ends of the movable plate 2. The slide groove 203 and the slide bar 204 are used in conjunction with each other to make the movable plate 2 and the spectrometer body 1 slidably connected.

[0028] When in use, first place the left end of the movable plate 2 in contact with the right end of the groove 11, and insert the two slide bars 204 into the two slide grooves 203 respectively, then pull the connecting rod 232 outward to unfold the two supporting rods 23 and put them in a vertical state, and make the movable wheel 22 contact with the work surface, so as to realize the use of the assembly formed by the two movable wheels 22, the two supporting rods 23 and the connecting rod 232 to lift the movable plate 2 outward, effectively reducing the probability of deformation of the movable plate 2 due to its own weight, effectively reducing the probability of misalignment between the cuvette 3 and the corresponding detection hole on the bottom end of the groove 11, effectively ensuring that the cuvette 3 can be normally inserted into the detection hole, and effectively ensuring the inspection effect; Then, the movable plate 2 is pushed to the left, thereby making the slide bar 204 move to the left along the slide groove 203, and making the two supporting rods 23, the magnetic strip 231 and the connecting rod 232 move to the left, and the two movable wheels 22 will guide the movement of the movable plate 2. When the movable plate 2 completely covers the opening of the groove 11, the magnetic strip 231 will fit with the iron block 202. At this time, the magnetism of the magnetic strip 231 itself will adsorb the iron block 202, so as to achieve stable installation of the covered movable plate 2, effectively reduce the probability of displacement of the movable plate 2 and other components due to factors such as crushing, effectively reduce the probability of misalignment between the cuvette 3 and the corresponding detection hole on the bottom end of the groove 11, effectively ensure that the cuvette 3 can be normally inserted into the detection hole, and effectively ensure the inspection effect; After the inspection of the chemical composition of food pigments is completed, the electromagnet 42 is first released from the adsorption of the plurality of iron plates 31, and the cuvette 3 is allowed to stay on the corresponding detection hole at the bottom end of the groove 11, and then the connecting rod 232 is pulled to the right to separate the magnetic strip 231 from the iron block 202, and the movable plate 2 is moved to the right, so as to separate the movable plate 2 from the groove 11, and separate the slide bar 204 from the slide groove 203, and then the movable plate 2 is disassembled from the spectrometer body 1, and then the cuvette 3 in the groove 11 is taken out and cleaned, and then the cleaned cuvette 3 is stored; Then the inner cavity formed by the processing box 5, the functional box 6 and other components is cleaned, and then the two support rods 23 are folded by using elastic hinges, so that the two support rods 23 and the connecting rod 232 are fitted with the lower end of the movable plate 2. At this time, the magnetic strip 231 and the iron sheet 201 are fitted with each other. At this time, the magnetism of the magnetic strip 231 itself will adsorb the iron sheet 201, so as to fold the assembly formed by the two moving wheels 22, the two support rods 23 and the connecting rod 232, and then the moving plate 2 and other components are stored, so as to realize the folding of the assembly formed by the two moving wheels 22, the two support rods 23 and the connecting rod 232, which effectively facilitates the subsequent storage operations.
