Technical Field

[0001] This utility model relates to the field of food processing technology, specifically to a sampling device for food safety testing. Background Technology

[0002] Food inspection is a discipline that uses physical, chemical, and biochemical principles to test the quality of food raw materials, auxiliary materials, semi-finished products, finished products, and by-products. It encompasses sensory testing, nutritional analysis, and the detection of additives and harmful substances. Methods include chromatography and spectroscopy, covering the testing of both inorganic and organic components, and surface-enhanced laser Raman spectroscopy is used for the rapid detection of substances such as melamine and Sudan Red.

[0003] Because food processing production lines produce a large number of products, sampling testing is usually used to improve testing efficiency. This involves taking multiple samples of food produced that day and mixing them for testing. However, existing sampling devices need to be replaced after each sampling, and the samples need to be mixed together during testing, which is inconvenient and needs improvement. Utility Model Content

[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0018] Example 1 Combined with appendix Figure 1-5 A sampling device for food safety testing includes a conveyor belt body 1, a telescopic rod 2 on the conveyor belt body 1, a clamping mechanism 3 at the output end of the telescopic rod 2, and a sampling device 4 that cooperates with the conveyor belt body 1 at the output end of the clamping mechanism 3.

[0019] Personnel place the produced food or the food to be tested onto the conveyor belt body 1 in sequence. The conveyor belt body 1 moves the food. When the food moves to below the sampling device 4, the telescopic rod 2 extends, causing the clamping mechanism 3 and the sampling device 4 to move downwards, allowing the sampling device 4 to extend into the food. The clamping mechanism 3 then releases its grip on the sampling device 4, and the sampling device 4 resets, extracting liquid from the food. The above steps are repeated to sample different foods. After sampling, personnel remove the sampling device 4 and test the sample in the sampling device 4. If an abnormality is found in the sample, all food from the first to the last sampling of this sampling device is discarded, or all food from the first to the last sampling of this sampling device is sampled again separately for testing. Unqualified food is discarded, while qualified food can be packaged and sold.

[0020] Example 2 Combined with appendix Figure 2 , 4 5. The sampling device 4 includes a balloon 5 located at the output end of the clamping mechanism 3. A sampling tube 6 is connected to the bottom of the balloon 5. A first one-way valve 7 is connected to the sampling tube 6. An L-shaped air guide tube 8 is connected to the side wall of the balloon 5. A second one-way valve 9 is connected to the end of the L-shaped air guide tube 8 away from the balloon 5.

[0021] The hemispherical groove 16 is provided with an anti-slip pad 18 that cooperates with the balloon 5.

[0022] The balloon 5 has an automatic reset function. When the clamping mechanism 3 clamps the balloon 5, it will deform the balloon 5. The air in the balloon 5 will be discharged through the L-shaped air duct 8, so that the air in the balloon 5 is discharged. When sampling food, the clamping mechanism 3 releases the clamp on the balloon 5, the balloon 5 resets, and a negative pressure is formed inside the balloon 5. The sampling tube 6 absorbs the liquid in the food. The hemispherical groove 16 can make the clamping mechanism 3 clamp the balloon 5 better, and the anti-slip pad 18 can increase the friction between the balloon 5 and the hemispherical groove 16.

[0023] Example 3 Combined with appendix Figure 4 The conveyor belt body 1 is provided with a U-shaped frame 10, and the telescopic rod 2 is provided on the U-shaped frame 10. The U-shaped frame 10 can support the telescopic rod 2.

[0024] The clamping mechanism 3 includes a U-shaped part 11 located at the output end of the telescopic rod 2. One end of the U-shaped part 11 is provided with a pulse motor 12. The output end of the pulse motor 12 is provided with a positive and negative screw 13 connecting the two ends of the U-shaped part 11. A screw block 14 fitted to the positive and negative screw 13 is sleeved on the screw block 13 and fits against the U-shaped part 11. The output end of the screw block 14 is provided with a clamping plate 15. The clamping plates 15 are provided with a hemispherical groove 16 that cooperates with the balloon 5 at their close ends.

[0025] The pulse motor 12 drives the positive and negative screws 13 to rotate. The positive and negative screws 13 drive the screw block 14 and the clamping plate 15 to move closer together to clamp and fix the balloon 5. When sampling food, the pulse motor 12 drives the positive and negative screws 13 to rotate in the opposite direction, so that the screw block 14 and the clamping plate 15 move away from each other, so that the clamping plate 15 loosens its clamping on the balloon 5, the balloon 5 resets, and a negative pressure is formed inside the balloon 5, so that the sampling tube 6 can draw liquid from the food for sampling.

[0026] A light rod 17 is connected between the U-shaped parts 11. The screw block 14 is sleeved on the light rod 17. The light rod 17 can limit the movement of the screw block 14, making the movement of the screw block more stable.

[0027] The conveyor belt body 1, telescopic rod 2, and pulse motor 12 mentioned in this utility model, as well as their matching power supply and controller, can be provided by the manufacturer. Apart from that, the circuits, electronic components, and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon.

[0028] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions, alterations, deletions of some features, additions of features, or recombinations of features to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the innovative principles of the present invention shall still fall within the scope of the technical solutions of the present invention.
