[0002] In the food inspection process, food and reagents need to be mixed using a food sample mixing device to meet the testing standards. Existing food sample mixing devices can generally only mix one set of food and reagents. After one set of food and reagents is mixed, another set of food and reagents needs to be loaded and unloaded, which is cumbersome and affects the efficiency of food inspection and testing. To address this, we propose a special sample mixing device for food inspection and testing. Utility Model Content

[0003] The purpose of this invention is to provide a sample preparation and mixing device specifically for food inspection and testing, which solves the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a special sample preparation and mixing device for food inspection and testing, comprising a base plate, a turntable, and a mixing tank. A support plate is fixedly installed near one side of the top of the base plate, and a motor is fixedly installed on the outer side of the support plate. The turntable is driven by the motor. A rotating shaft is fixedly connected to one end of the mixing tank, passing through the turntable and rotatably connected to the turntable via a bearing. A gear is fixedly installed at one end of the rotating shaft. A fixing rod is fixedly connected to the inner side of the support plate, and a gear ring is fixedly installed at one end of the fixing rod. The gear meshes with the gear ring. A cover plate is engaged in the feed inlet on the outer wall of the mixing tank. The cover plate is fixedly connected to the mixing tank via fasteners. A sealing plate is fixedly connected to the other open end of the mixing tank via fasteners. A connecting rod is fixedly installed on the inner side of the sealing plate. A cutting plate is fixedly installed on the outer wall of the connecting rod. A scraper is fixedly installed at one end of the connecting rod, and the scraper is slidably connected to the inner wall of the mixing tank.

[0005] Preferably, the number of mixing tanks is four.

[0006] Preferably, a second rotating shaft is fixedly installed at the output end of the motor. The second rotating shaft passes through the first support plate and is rotatably connected to the first support plate via a bearing. The turntable is fixedly installed at one end of the second rotating shaft. By setting the second rotating shaft, the motor can drive the turntable to rotate via the second rotating shaft.

[0007] Preferably, a second support plate is slidably connected to the top of the bottom plate, and an annular groove is formed on the inner side of the second support plate. A pull rod is fixedly installed on the outer side of the sealing plate, and a support block is fixedly installed at one end of the pull rod. A ball groove is formed on the outer wall of the support block, and a ball is rolled and embedded in the ball groove. The support block extends into the annular groove, and the ball is rolled and connected to the inner wall of the annular groove. An electric cylinder is fixedly installed on the top of the bottom plate near the other side, and the second support plate is fixedly installed at one end of the piston rod of the electric cylinder. By setting the ball, the friction between the support block and the annular groove can be reduced, thereby improving the flexibility of the mixing tank when rotating.

[0008] Preferably, the connecting rod has several cutting plates, which can be used to divide and stir the food in the mixing tank.

[0009] Preferably, retaining rings are provided on both sides of the turntable. The retaining rings are fixedly sleeved on the outer wall of the rotating shaft.

[0018] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0019] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example 1:

[0021] A preferred embodiment of the food testing and inspection sample preparation and mixing device provided by this utility model is, for example... Figures 1 to 4The following describes a sample preparation and mixing device for food inspection and testing: It includes a base plate 1, a turntable 4, and a mixing tank 5. A support plate 2 is fixedly installed near one side of the top of the base plate 1. A motor 3 is fixedly installed on the outer side of the support plate 2. The turntable 4 is connected to the motor 3 via a transmission connection. A rotating shaft 6 is fixedly connected to one end of the mixing tank 5, passing through the turntable 4 and rotatably connected to the turntable 4 via a bearing. A gear 7 is fixedly installed at one end of the rotating shaft 6. A fixing rod 9 is fixedly connected to the inner side of the support plate 2. A gear ring 8 is fixedly installed at one end of the fixed rod 9. The gear 7 meshes with the gear ring 8. A cover plate 11 is engaged in the feed inlet on the outer wall of the mixing tank 5. The cover plate 11 is fixedly connected to the mixing tank 5 by fasteners. A sealing plate 12 is fixedly connected to the other opening end of the mixing tank 5 by fasteners. A connecting rod 13 is fixedly installed on the inner side of the sealing plate 12. A cutting plate 14 is fixedly installed on the outer wall of the connecting rod 13. A scraper 15 is fixedly installed at one end of the connecting rod 13. The scraper 15 is slidably connected to the inner wall of the mixing tank 5.

[0022] Specifically, in the above technical solution, when using the food testing and inspection sample preparation and mixing device, four groups of food and reagents are placed into the mixing tank 5 respectively. Then, the electric cylinder 22 is activated, which drives the second support plate 21 to move towards the mixing tank 5, so that the support block 17 is inserted into the annular groove 18, and the ball bearing 20 contacts the inner wall of the annular groove 18. Then, the motor 3 is activated, which drives the second rotating shaft 10 to rotate. The second rotating shaft 10 drives the turntable 4 to rotate, and the turntable 4 drives the mixing tank 5 to rotate in a circular motion through the first rotating shaft 6. The first rotating shaft 6 drives the gear 7 to rotate in a circular motion, and the gear 7 rotates under the action of the gear ring 8. The gear 7 drives the mixing tank 5 to rotate through the first rotating shaft 6, thereby making the food and reagents in the mixing tank 5 fully mixed under the action of the cutting plate 14. Through the above structure, multiple groups of food and reagents can be mixed simultaneously. This improves the efficiency of food testing and solves the problem that existing food sample mixing devices can only mix one set of food and reagents at a time. After one set of food and reagents is mixed, another set of food and reagents needs to be loaded and unloaded, which is cumbersome and affects the efficiency of food testing. After the food and reagents are mixed, the electric cylinder 22 is activated to retract, causing the support plate 21 to move outward and the support block 17 to disengage from the annular groove 18. Then, the fasteners between the sealing plate 12 and the mixing tank 5 are unscrewed, and the sealing plate 12 is pulled outward by the pull rod 16. The sealing plate 12 drives the scraper 15 to move outward through the connecting rod 13, so that the scraper 15 can scrape the food out of the mixing tank 5, thus completing the unloading. By setting the scraper 15, it is easy for personnel to remove the mixed food from the mixing tank 5, which is convenient for personnel operation.

[0023] Furthermore, there are four mixing tanks 5.

[0024] Furthermore, a rotating shaft 10 is fixedly installed at the output end of motor 3. The rotating shaft 10 passes through the support plate 2 and is rotatably connected to the support plate 2 through a bearing. The turntable 4 is fixedly installed at one end of the rotating shaft 10.

[0025] Among them, by setting a second rotating shaft 10, the motor 3 can drive the turntable 4 to rotate through the second rotating shaft 10.

[0026] Furthermore, retaining rings 23 are provided on both sides of the turntable 4, and the retaining rings 23 are fixedly sleeved on the outer wall of the rotating shaft 6;

[0027] By setting the retaining ring 23, the rotating shaft 6 can be limited, thereby improving the stability of the rotating shaft 6 when it rotates on the turntable 4. Example 2:

[0028] Based on Embodiment 1, a preferred embodiment of the food testing and inspection sample preparation and stirring device provided by this utility model is, for example... Figures 1 to 4 As shown: A second support plate 21 is slidably connected to the top of the base plate 1. An annular groove 18 is provided on the inner side of the second support plate 21. A pull rod 16 is fixedly installed on the outer side of the sealing plate 12. A support block 17 is fixedly installed at one end of the pull rod 16. A ball groove 19 is provided on the outer wall of the support block 17. A ball 20 is rolled in the ball groove 19. The support block 17 extends into the annular groove 18, and the ball 20 is rolledly connected to the inner wall of the annular groove 18. An electric cylinder 22 is fixedly installed on the top of the base plate 1 near the other side. The second support plate 21 is fixedly installed at one end of the piston rod of the electric cylinder 22.

[0029] By incorporating ball bearings 20, the friction between the support block 17 and the annular groove 18 can be reduced, thereby improving the flexibility of the mixing tank 5 during rotation.

[0030] Specifically, the above technical solution involves setting up a support plate 21, annular groove 18, support block 17, and ball bearings 20, which can provide certain support for the mixing tank 5 when it is making circular motion, thereby improving the stability of the mixing tank 5 during motion. The structure is simple and highly practical.

[0031] Furthermore, the number of cutting plates 14 on the connecting rod 13 is several;

[0032] The food in the mixing tank 5 can be divided and mixed by setting the cutting plate 14.

[0033] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
