Description

Technical Field

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

[0002] Food safety refers to food that is non-toxic, harmless, meets the necessary nutritional requirements, and does not cause any acute, subacute, or chronic harm to human health. According to Beno's definition of food safety, food safety is "a public health issue concerning the impact of toxic or harmful substances in food on human health." Food safety is also an interdisciplinary field that specifically explores ensuring food hygiene and safety during food processing, storage, and sales, reducing disease risks, and preventing food poisoning. Therefore, food safety is very important.

[0003] In various food testing processes, sample preparation is required before testing with specialized instruments. Currently, most sample preparation devices are divided into powder mixing type and solid cutting type. Traditional sample preparation often uses knives or guillotines for cutting, which makes it difficult to cut food into similar-sized blocks. Therefore, we have proposed a new food sample preparation device. Utility Model Content

If the specific posture changes, the directional indications will also change accordingly.

[0028] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0029] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0030] In related technologies, most sample preparation devices are now divided into powder mixing type and solid cutting type. Traditional sample preparation often uses a knife or a guillotine cutter for cutting, which makes it difficult to cut food into similar-sized block structures.

[0031] To address some of the problems in the related technologies, this application provides a sample preparation device for food testing. When needed, it only requires setting up a mechanism that can adjust the distance between the two cutting blades 15. After cutting, the food can be cut again by rotating the placement seat 21 by 90 degrees to obtain a regular block-shaped sample.

[0032] This application is described below with reference to the accompanying drawings and specific embodiments:

[0033] Combination Figures 1-4 This application provides a sample preparation device for food testing, including a cutting device 1. The cutting device 1 includes: a base 11 with a fixed seat 12 on top; a shaft 13 disposed inside the fixed seat 12 and rotatably connected to the fixed seat 12; rods 14 disposed at both ends of the shaft 13; cutting blades 15 disposed between the rods 14; collars 16 disposed at both ends of the cutting blades 15 and sleeved on the rods 14; and a fixing ring 17 sleeved on the outer wall of the rods 14 and threadedly connected to the rods 14.

[0034] When using it, first adjust the position of the two cutting blades 15. Move the collars 16 at both ends of the cutting blades 15 on the rod 14 to adjust the required spacing. Then rotate the fixing ring 17 so that the two fixing rings 17 clamp and fix one of the collars 16 to prevent the collar 16 and the cutting blade 15 from moving further. Then rotate the rod 14 downward so that the cutting blade 15 cuts the food placed on the base 11. After cutting, rotate the food 90 degrees and cut it again to obtain a block-shaped test sample of regular size, which can be detected by instruments such as liquid chromatography and pesticide residue detector.

[0035] In some embodiments, a connecting rod 141 is provided between the rod bodies 14, and an anti-slip sleeve 142 is fitted on the outer wall of the connecting rod 141. The connecting rod 141 connects the rod bodies 14 to form a whole, increasing stability, and the anti-slip sleeve 142 is for the convenience of the hand to grip the connecting rod 141.

[0036] In some embodiments, the rod 14 passes through the shaft 13, and a nut is threaded onto one end of the rod 14. One end of the rod 14 passes through the shaft 13, and then the nut is screwed on for fixation.

[0037] In some embodiments, the outer side wall of the retaining ring 17 is provided with a protruding rod 18. The protruding rod 18 is a short rod that protrudes from the surface of the retaining ring 17, making it convenient to rotate the retaining ring 17 by hand without the use of tools.

[0038] In some embodiments, the cutting device 1 is provided with an auxiliary component 2, which includes: a support column 25 disposed on the top of the base 11; and a fixing groove 26 formed on the top of the support column 25. When the rod 14 rotates downward to cut food, the fixing groove 26 on the top of the support column can support the rod 14.

[0039] In some embodiments, a rotating shaft 27 is rotatably connected to the top of the support column 25, and a cover plate 28 is provided on the top of the rotating shaft 27. The cover plate 28 has a magnetic attraction structure. By rotating the cover plate 28 through the rotating shaft 27, after the rod 14 enters the fixing groove 26, the cover plate 28 and the support column 25 are magnetically attracted, fixing and limiting the rod 14 to prevent it from being lifted.

[0040] In some embodiments, a placement seat 21 is provided on the top of the base 11, the placement seat 21 is rotatably connected to the base 11, and a connecting plate 22 is provided on the outer side wall of the placement seat 21. Food to be cut is placed on the placement seat 21, and the connecting plate 22 is pushed by hand to rotate the placement seat 21, facilitating the rotation and cutting of the food.

[0041] In some embodiments, a ring 24 is fitted onto the outer wall of the rod 14, and a scale 23 is provided on the outer wall of the ring 24. The scale 23 moves left and right on the rod 14 via the ring 24 to measure the distance between the two cutting blades 15.
