Technical Field

[0001] The utility model relates to the technical field of food detection, in particular to a sampling device for detecting selenium-rich food. Background Art

[0002] Selenium-rich milk powder can enhance the body's immunity, protect cardiovascular function, maintain the healthy function of the visual organs, and effectively protect eyesight. The selenium supplemented by selenium-rich milk powder can participate in the formation of various enzymes in the human body, and participate in regulating human growth and development, and promote brain development.

[0003] In the process of manufacturing selenium-enriched milk powder, it is necessary to sample and test the product. At present, milk powder sampling mainly relies on manual scooping of milk powder, and the actual test value is often related to the amount of milk powder extracted. Therefore, if the quantitative sampling of milk powder products to be tested cannot be guaranteed, the difference in the test values ​​of milk powder between the previous and next batches will increase.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] In this embodiment, refer to Figure 1-3 A sampling device for detecting selenium-rich food comprises a placing table 1, on both sides of which are provided vertical frames 2, and between which are connected a lifting mounting bracket 7 through a screw mechanism 4. Figure 1 As shown, the screw mechanism 4 includes a screw rod vertically arranged inside the stand 2, a nut pair threadedly connected to the screw rod, and a transmission motor 18 arranged on the upper surface of the top plate 3 at the top of the stand 2, and the rotation of the screw rod is controlled by the transmission motor 18.

[0023] As attached Figure 1 or attached Figure 2 As shown, a rotating wheel disc 5 rotating coaxially is arranged on one side of the mounting bracket 7. The rotating center of the rotating wheel disc 5 is rotatably mounted on the outer surface of the nut pair through a bearing component. A vertical plate 6 is arranged on the inner surface of the vertical frame 2 on one side. The rotating wheel disc 5 is a half gear. A row of racks that mesh with the rotating wheel disc 5 are arranged on the plate surface of the vertical plate 6 facing the rotating wheel disc 5. It should be particularly noted that in combination with the attached Figure 2 It can be seen that the rack provided on the vertical plate 6 is located in the upper half of the screw rod stroke.

[0024] The mounting bracket 7 can be controlled to rise and fall vertically by means of a lead screw transmission. During the process of the mounting bracket 7 being lowered, the rotating wheel disc 5 arranged on one side of the mounting bracket 7 will first mesh with the rack and drive the entire mounting bracket 7 to rotate counterclockwise. After the rotating wheel disc 5 is separated from the rack, the mounting bracket 7 can remain in a vertical state. During the process of the mounting bracket 7 being lifted, the mounting bracket 7 first remains in a vertical state, and after the rotating wheel disc 5 comes into contact with the rack and begins to mesh, it will drive the entire mounting bracket 7 to rotate clockwise.

[0025] In order to improve the stability of the mounting bracket 7 when it is lifted up and down, a horizontal extension column is installed on the side of the mounting bracket 7 opposite to the rotating wheel 5 through a bearing component. The extension column extends outward into the vertical frame 2 on the corresponding side, and a slide cylinder 20 is provided at the end of the extension column. A vertical guide rod 19 is installed in the vertical frame 2 on this side, and the slide cylinder 20 is slidably mounted on the guide rod 19.

[0026] As attached Figure 2 or attached Figure 3As shown, a mounting plate 8 is provided at the bottom of the mounting bracket 7, a cylinder 9 is provided on the upper half of the plate surface of the mounting plate 8, and a suspension plate 10 is provided on the lower half. The suspension plate 10 is a U-shaped plate, and two arms of the suspension plate 10 are fixed to the mounting plate 8 by fasteners. A piston rod provided at the output end of the cylinder 9 extends into the inner side of the suspension plate 10 and is connected to a mounting frame 12. The lower end of the mounting frame 12 is connected to a movable arm 14 arranged crosswise in a clamp arm type through a fixed shaft 13;

[0027] Guide grooves 11 are respectively provided on both sides of the board surface of the suspension board 10, and a sliding ball 15 is provided on the upper end of the movable arm 14. The sliding ball 15 is built into the guide groove 11 and slides along it. Figure 3 It can be seen that the upper halves of the guide grooves 11 on both sides of the board surface of the suspension board 10 are relatively parallel, and the lower halves of the guide grooves 11 on both sides are relatively convergent and form a symmetrical inward-facing "X" shape.

[0028] Finally, it should be noted that a sampling cup 16 is disposed at the lower end of one of the movable arms 14 , and a baffle 17 is disposed at the lower end of the other movable arm 14 . The baffle 17 rotates and covers the cup mouth of the sampling cup 16 .

[0029] The mounting frame 12 is controlled to slide vertically by the cylinder 9. When the mounting frame 12 slides downward, the sliding beads 15 on both sides slide to the bottom along the guide groove 11. At this time, the sampling cup 16 and the baffle 17 can be assembled together. When the mounting frame 12 slides upward, the sliding beads 15 on both sides slide to the top along the guide groove 11. At this time, the sampling cup 16 and the baffle 17 can be automatically separated.

[0030] In the actual sampling process, the staff only needs to place the milk powder barrel to be sampled on the holding table 1 and directly below the mounting bracket 7. First, the sampling cup 16 and the baffle 17 are controlled to extend into the milk powder barrel by means of a screw drive, and then the sampling cup 16 and the baffle 17 are controlled to be spliced ​​by the cylinder 9. At this time, the milk powder has been taken out of the sampling cup 16. Then, the sampling cup 16 and the baffle 17 are controlled to be withdrawn from the milk powder barrel by means of a screw drive, and then turned to one side, and then the sampling cup 16 and the baffle 17 are controlled to be separated by the cylinder 9. At this time, the mouth of the sampling cup 16 automatically opens, and the staff only needs to receive it under the mouth of the sampling cup 16. Since the volume of the sampling cup 16 is fixed, it can be ensured that a certain amount of milk powder is taken for testing each time.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
