[0048] Reference Figure 1-Figure 6 , an extraction device for food detection, comprising an operating table 1, a displacement drive component 2, a carrying plate 3, a material placement seat 4 and a stirring component 5, wherein the displacement drive component 2 is disposed on one side of the operating table 1;

[0049] The displacement drive assembly 2 includes a support 21, a screw component 22, a driver 23 and a slide 24. The support 21 is arranged on one side of the operating table 1. The screw component 22 is movably installed in the support 21. The driver 23 is arranged at the top of the support 21. The output end of the driver 23 is connected to the screw component 22 through a coupling. The driver 23 provides power for the rotation of the screw component 22. The driver 23 is a servo drive motor in the prior art. The slide 24 is connected to the bearing plate 3. The material placement seat 4 is arranged on the bearing plate 3. The material placement seat 4 is provided with a clamping component 6 for mounting an extraction bottle.

[0050] Through the cooperation of the displacement driving component 2 and the carrying plate 3, the material placement seat 4 can be relatively moved along the length direction of the screw rod component 22, and the material placement seat 4 can be driven to move through the cooperation of the displacement driving component 2, so that the extraction bottle clamped by the clamping component 6 can be moved synchronously;

[0051] The stirring assembly 5 is arranged on the supporting plate 3, and the stirring assembly 5 includes a support rod 51, a connecting seat 52 and a stirring component 53. The support rod 51 is located on one side of the material placement seat 4, and the connecting seat 52 is movably arranged on the support rod 51 and connected to the stirring component 53. The stirring component 53 is displaced above the clamping component 6. The stirring component 53 is a stirrer driven by a motor in the prior art, which can stir the material in the extraction bottle.

[0052] Based on the above structure, the extraction bottle to be extracted is filled with materials and placed on the clamping component 6. Since the clamping component 6 is installed on the material placement seat 4 connected to the carrying plate 3, and the carrying plate 3 is connected to the slide 24, when the driver 23 controls the screw component 22 to rotate, the slide 24 can drive the carrying plate 3 to move along the rotation direction of the screw component 22. The reciprocating movement of the carrying plate 3 can be achieved by the forward and reverse rotation of the driver 23. During the reciprocating movement, the materials in the extraction bottle will shake, thereby simulating the shaking of the extraction bottle during manual operation, and then Since the stirring assembly 5 is located on the supporting plate 3, the stirring component 53 is connected to the connecting seat 52 which is movably arranged on the support rod 51. Therefore, the position of the stirring component 53 is changed by moving the connecting seat 52, so that the stirring rod in the stirring component 53 is located in the extraction bottle to stir it. Through the cooperation of the displacement driving assembly 2 and the stirring assembly 5, the operation of shaking and stirring the material in the extraction bottle during manual inspection is simulated, and a uniform stirring and shaking force is achieved, thereby solving the problem that the force and speed of manual stirring are difficult to accurately control, affecting the repeatability and consistency of the extraction process.

[0053] In one embodiment, referring to Figure 1 , Figure 2 and Figure 6 The clamping component 6 includes a support block 61, a guide rod 62, a clamping plate 63 and a bracket 64. The support block 61 is arranged outside the material placement seat 4. The support block 61 is provided with two groups of spaced apart. The guide rod 62 is arranged between the two groups of support blocks 61. The clamping plate 63 is sleeved on the guide rod 62 so that the clamping plate 63 can move relatively along the length direction of the guide rod 62. The clamping plate 63 is used to clamp the extraction bottle to be placed. By installing the clamping plate 63 on the guide rod 62, the position can be adjusted according to the extraction bottles of different heights, thereby improving the use flexibility of the clamping component 6 and avoiding the situation of unstable clamping.

A plurality of clamping components 6 are provided and evenly distributed around the material placement seat 4. By rotating the material placement seat 4 on the annular support portion 31, the clamping components 6 can be placed at different angles of the material placement seat 4, so that multiple extraction bottles can be shaken or stirred on the material placement seat 4, thereby improving the efficiency of detection.

The two groups of limiting plates 72 form an accommodating area for placing the extraction bottle. Since the diameters of extraction bottles of different sizes are different, the elastic components 71 and the limiting plates 72 in the limiting components 7 cooperate to support the limiting plates 72 according to the characteristics of the elastic components 71. Therefore, when the limiting plates 72 are fixed to extraction bottles of different diameters, they can always be against the bottle body, thereby improving the flexibility of the limiting components 7.
