[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0034] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "first"..."third" are numbered for the purpose of clearly identifying product components and do not represent any substantial difference. The terms "installed," "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 direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this utility model according to the specific circumstances. Furthermore, "multiple" means two or more. In the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following related objects are in an "or" relationship.

[0035] The following combination Figure 1-Figure 3 This invention describes a shaking device and a dairy product testing station for testing dairy products.

[0036] like Figure 1-Figure 3 As shown in the embodiment of this utility model, a shaking device and a dairy product testing station for testing dairy products are provided.

[0037] The shaking device for dairy product testing provided in this embodiment of the invention includes a test tube rack 1 and a rotating mechanism 2. The test tube rack 1 has slots 10 suitable for inserting test tubes 6. The rotating mechanism 2 includes a driving component (not shown) and a first rotating wheel 21. The driving component is kinetically connected to the first rotating wheel 21 and drives the first rotating wheel 21 to rotate back and forth. The first rotating wheel 21 is located on one side of the test tube rack 1, and a plurality of first protrusions 211 are spaced apart on the rim of the first rotating wheel 21. The test tubes 6 can rotate and tilt within the slots 10 under the action of each first protrusion 211.

[0038] Understandably, to ensure that test tube 6 can be smoothly inserted into slot 10, the inner diameter of slot 10 will be slightly larger than the outer diameter of test tube 6. Both test tube 6 and the axis of rotation of the first rotating wheel 21 are placed vertically. See [link / reference] Figure 2When the first rotating wheel 21 rotates, the first protrusion 211 on its rim will apply a certain squeezing force to the side wall of the test tube 6. This squeezing force can, on the one hand, make the test tube 6 rotate in the slot, and on the other hand, push the test tube 6 to shake in the slot 10.

[0039] Specifically, when the driving component drives the first rotating wheel 21 to rotate in the forward direction, the first protrusion 211 on the first rotating wheel 21 causes the test tube 6 to rotate in the reverse direction by a certain angle, and at the same time pushes the test tube 6 to tilt at a certain angle away from the first rotating wheel 21. See Figure 3 The dashed circle represents the position of test tube 6 before it is rotated and tilted, while the solid circle represents the position of test tube 6 after it is rotated and tilted. After the first protrusion 211 moves away from test tube 6, test tube 6 automatically returns to the position indicated by the dashed line.

[0040] Then, the first rotating wheel 21 continues to rotate, and the second first protrusion 211 drives the test tube 6 to rotate at a certain angle, while simultaneously pushing the test tube 6 to tilt at a certain angle away from the first rotating wheel 21. After the second first protrusion 211 moves away from the test tube 6, the test tube 6 automatically returns to its normal position. This process continues until multiple first protrusions 211 act on the test tube 6, causing it to undergo multiple reverse rotations and tilts. Then, the driving component drives the first rotating wheel 21 to rotate in the opposite direction, continuing to act on the test tube 6 through multiple first protrusions 211, causing the test tube 6 to undergo multiple forward rotations and tilts. In this way, the driving component drives the first rotating wheel 21 to rotate back and forth multiple times, causing the test tube 6 to repeatedly undergo multiple forward rotations and shaking, as well as multiple reverse rotations and shaking, ensuring that the sample and diluent inside are thoroughly mixed.

[0041] The shaking device for dairy product testing provided in this embodiment of the invention comprises a test tube rack 1 and a rotating mechanism 2. The first rotating wheel 21 of the rotating mechanism 2 has multiple first protrusions 211 spaced apart on its rim. The rotating mechanism 2's drive unit drives the first rotating wheel 21 to reciprocate, allowing each first protrusion 211 to act on the test tube 6, causing the test tube 6 to rotate and tilt within the slot 10 of the test tube rack 1. Through the reciprocating rotation of the first rotating wheel 21, the test tube 6 is able to rotate and tilt multiple times in both directions within the slot 10, ensuring thorough mixing of the material within the test tube 6. This shaking device can replace manual shaking, reducing manual steps, lowering the possibility of cross-contamination between different samples, and improving shaking efficiency and consistency.

[0042] It should be noted that the shaking device for dairy product testing provided in this embodiment is not limited to shaking samples and diluents, but is also applicable to shaking any two liquids, such as shaking samples and test reagents.

[0043] In this embodiment of the invention, there are multiple slots 10, which are arranged sequentially at intervals. Specifically, the multiple slots 10 are arranged at intervals along a straight line. The first rotating wheel 21 can sequentially shake the multiple test tubes 6 in the multiple slots 10. The test tube rack 1 and the first rotating wheel 21 are movable relative to each other, and their relative movement direction is the same as the arrangement direction of the multiple slots 10.

[0044] Specifically, the shaking device for dairy product testing provided in this embodiment further includes a moving mechanism. The test tube rack 1 or a driving component is mounted on the moving mechanism and can move along the arrangement direction of the multiple slots 10 under the action of the moving mechanism. After the shaking operation of one test tube 6 on the test tube rack 1 is completed by the first rotating wheel 21, the moving mechanism drives the test tube rack 1 or the rotating mechanism 2 to move along the arrangement direction of the multiple slots 10, so that the first rotating wheel 21 acts on the next test tube 6, and the shaking operation of multiple test tubes 6 is completed in sequence.

[0045] In the case where the test tube rack 1 is integrated into the moving mechanism, the moving mechanism can be a conveyor belt 5. Optionally, the test tube rack 1 is fixedly connected to the moving mechanism by a fastener to prevent the test tube rack 1 from tipping over under the action of the first rotating wheel 21. In the case where the driving element is integrated into the moving mechanism, the moving mechanism can be a linear drive motor.

[0046] The shaking device for dairy product testing provided in this embodiment also includes a base 3 and a second rotating wheel 4. The driving component is fixed to the base 3, and the second rotating wheel 4 is rotatably connected to the base 3. The second rotating wheel 4 and the first rotating wheel 21 are respectively disposed on both sides of the test tube rack 1. Multiple second protrusions 41 are spaced apart on the rim of the second rotating wheel 4, and the test tube 6 can be supported between the grooves formed by two adjacent second protrusions 41.

[0047] like Figure 1 As shown, the shaft of the second rotating wheel 4 is arranged vertically, and the first rotating wheel 21 and the second rotating wheel 4 are respectively located on both sides of the test tube rack 1. When the test tube rack 1 is provided with multiple slots 10, the first rotating wheel 21 and the second rotating wheel 4 are respectively located on both sides of the arrangement direction of the multiple slots 10.

[0048] When the test tube 6 in one of the slots 10 is shaken, that is, during the rotation of the first rotating wheel 21, the test tube 6 rotates and tilts in the slot 10, and the test tube 6 is located between the two second protrusions 41 of the second rotating wheel 4. The groove formed by the two second protrusions 41 of the second rotating wheel 4 provides support for the test tube 6, which can limit the tilt angle of the test tube 6 and prevent the test tube rack 1 from tipping over due to excessive tilt.

[0049] In this embodiment, the test tube rack 1 or the base 3 can be moved along the arrangement direction of the slots 10, causing relative movement between the two to achieve a shaking operation on multiple test tubes 6 sequentially. Since the second rotating wheel 4 is rotatably connected to the base 3, the next test tube 6 can smoothly enter between the two second protrusions 41 of the second rotating wheel 4. The spacing between two adjacent second protrusions 41 is adapted to the outer diameter of the test tube 6.

[0050] Optionally, the second rotating wheel 4 is mounted on the base 3 via a first adjusting mechanism, which adjusts the distance between the second rotating wheel 4 and the first rotating wheel 21 to accommodate test tubes 6 of different sizes. And / or, the driving component is mounted on the base 3 via a second adjusting mechanism, which adjusts the distance between the first rotating wheel 21 and the second rotating wheel 4 to accommodate test tubes 6 of different diameters.

[0051] The first and second adjustment mechanisms each include a slide rail, a slider, and a positioning element. The first rotating wheel 21 and the second rotating wheel 4 are fixed to the slider. The slider is slidably connected to the slide rail. The position of the positioning element in the length direction of the slide rail is adjustable. The slider can be fixed to the slide rail through the positioning element.

[0052] The shaking device for dairy product testing provided in this embodiment of the invention also includes a conveyor belt 5. The conveyor belt 5 is disposed on the base 3, and the test tube rack 1 is disposed on the conveyor belt 5. The conveyor belt 5 is used to drive the test tube rack 1 between the first rotating wheel 21 and the second rotating wheel 4. The length direction of the conveyor belt 5 is the same as the arrangement direction of the plurality of slots 10.

[0053] With the second rotating wheel 4 in place, the test tube 6 is supported by the second rotating wheel 4, which prevents the test tube rack 1 from tipping over under the action of the first rotating wheel 21. Therefore, the test tube rack 1 can be placed on the conveyor belt 5 without being fixed to the conveyor belt 5, which facilitates automated feeding to the conveyor belt 5.

[0054] like Figure 2 and Figure 3 As shown in the embodiment of this utility model, the first rotating wheel 21 and the second rotating wheel 4 are gears. The plurality of first protrusions 211 are the plurality of gear teeth on the first rotating wheel 21. The second protrusions 41 are the plurality of gear teeth on the second rotating wheel 4.

[0055] Optionally, the edges of the teeth of both the first rotating wheel 21 and the second rotating wheel 4 are rounded to avoid damage to the test tube 6 during high-speed operation. Optionally, the edges of the teeth of both the first rotating wheel 21 and the second rotating wheel 4 are provided with a flexible layer, which can reduce the rigid impact of the teeth on the test tube 6 and increase the friction between the teeth and the test tube 6.

[0056] Optionally, the first rotating wheel 21 and the second rotating wheel 4 have the same module. Optionally, the axial dimension of the second rotating wheel 4 is larger than the axial dimension of the first rotating wheel 21. For example, the axial dimension of the second rotating wheel 4 is one-third to one-half the length of the test tube 6, so that two adjacent second protrusions 41 of the second rotating wheel 4 form an elongated groove, providing more stable support for the test tube 6.

[0057] In some embodiments of this invention, the shaking device is provided with multiple sets of first rotating wheels 21 and second rotating wheels 4, and correspondingly with multiple driving components for driving the rotation of the multiple first rotating wheels 21. Multiple test tubes 6 can be shaken simultaneously by multiple sets of first rotating wheels 21 and second rotating wheels 4, further improving the shaking efficiency.

[0058] The shaking device for dairy product testing provided in this embodiment of the invention further includes a position detector and a controller. The position detector is used to detect when the test tube rack 1 reaches one side of the first rotating wheel 21. The position detector and the drive unit are respectively communicatively connected to the controller, which controls the start of the drive unit based on the detection result of the position detector.

[0059] Specifically, when the conveyor belt 5 moves the test tube rack 1 to one side of the first rotating wheel 21, it enters the detection range of the positioning detector. The positioning detector sends a detection signal to the controller. The controller determines that there is material to be mixed in this mixing area, and then controls the drive to start, causing the first rotating wheel 21 to begin reciprocating rotation for mixing. Correspondingly, when the conveyor belt 5 moves the test tube rack 1 outside the detection range of the positioning detector, the controller determines that there is no material to be mixed based on the detection signal from the positioning detector, and then controls the drive to shut down. This embodiment, by setting up a positioning detector and a controller, realizes the self-starting and self-shutting of the mixing device, improving the automation level of the mixing device.

[0060] The shaking device for dairy product testing provided in this embodiment of the invention further includes a barcode scanning mechanism and a controller. The barcode scanning mechanism is used to identify the sample identification code on the test tube 6. The barcode scanning mechanism and the driving component are respectively communicatively connected to the controller, which is used to determine the shaking mode based on the sample identification code and control the operation of the driving component according to the shaking mode.

[0061] Specifically, the scanning mechanism identifies the sample identification code on test tube 6 and sends it to the controller. The controller determines relevant information about the sample based on the sample identification code, such as its type or testing items. The controller has multiple preset shaking modes, each corresponding to different drive speeds, running times, or intervals. For different types of samples, the controller can use different shaking modes to perform the shaking operation, meeting diverse testing requirements.

[0062] For example, samples with different viscosities can be mixed at different speeds and for different running times to ensure that all samples are effectively and stably mixed, avoiding the generation of a large number of air bubbles that could affect the test results. For example, for samples with a thicker consistency, a faster speed and / or a longer running time are required.

[0063] In this embodiment of the invention, the test tube rack 1 has a first positioning part 11 and a second positioning part 12 arranged at intervals in the vertical direction. A first rotating wheel 21 is located between the first positioning part 11 and the second positioning part 12. The first positioning part 11 is provided with a first insertion hole, and the second positioning part 12 is provided with a second insertion hole. The first insertion hole and the second insertion hole are arranged opposite to each other to form a slot 10.

[0064] like Figure 1 As shown, the test tube rack 1 also includes a connecting part 13, which is arranged in a vertical direction. The first positioning part 11 and the second positioning part 12 are connected and fixed through the connecting part 13, and a certain distance gap is formed in the vertical direction to provide rotation space for the first rotating wheel 21 and avoid structural interference between the first rotating wheel 21 and the test tube rack 1.

[0065] Specifically, the connecting part 13 includes a first connecting part and a second connecting part. The first connecting part connects to one end of the first positioning part 11 and the second positioning part 12 that are opposite to each other, and the second connecting part connects to the other end of the first positioning part 11 and the second positioning part 12 that are opposite to each other.

[0066] Optionally, the first positioning part 11 is close to the bottom of the test tube 6, and the second positioning part 12 is close to the top of the test tube 6, so that when the test tube rack 1 is inserted into the first insertion hole and the second insertion hole, the test tube rack 1 can provide better support and protection for the test tube 6, and prevent the sample from tipping over and being lost during the shaking process.

[0067] Specifically, the first positioning part 11 includes a base plate and a first positioning plate spaced apart in the vertical direction. The first positioning plate is located above the base plate, and a first insertion hole is provided on the first positioning plate. The second positioning part 12 includes a second positioning plate and a third positioning plate spaced apart in the vertical direction, and a second insertion hole passes through the second positioning plate and the third positioning plate.

[0068] The base plate of the first positioning part 11 is the base plate of the test tube rack 1. The base plate, the first positioning plate, the second positioning plate, and the third positioning plate are arranged sequentially and at intervals in the vertical direction. The slot 10 passes through the first positioning plate, the second positioning plate, and the third positioning plate. When the test tube 6 is inserted into the slot 10, its bottom is supported on the base plate.

[0069] The shaking device for dairy product testing provided in this embodiment of the invention also includes a button (not shown in the figure), which is electrically connected to the drive component and is used to turn off the drive component. During the shaking operation of the shaker on the test tube 6, if the tester observes sample spillage from the test tube 6, the shaking operation can be terminated by pressing the button. The operator can adjust the shaking parameters for the sample, such as adjusting the rotation speed of the drive component.

[0070] In a specific example of this utility model, a test tube rack 1 is placed on a conveyor belt 5. The test tube rack 1 has multiple slots 10 arranged along the length of the conveyor belt 5. A first rotating wheel 21 and a second rotating wheel 4 are respectively located on both sides of the test tube rack 1. The conveyor belt 5 drives the test tube rack 1 through the gap between the first rotating wheel 21 and the second rotating wheel 4, and the first rotating wheel 21 sequentially shakes the test tubes 6 in the multiple slots 10. The controller controls the start and stop of the drive component according to the detection information of the positioning detector, and controls the drive component to run at a set speed, running time and interval period according to the sample identification code picked up by the scanning mechanism. This shaking device realizes automatic shaking of materials, reduces manual operation steps, and reduces the possibility of cross-contamination between different samples. Through the preset shaking mode, the shaking effect can be guaranteed and the shaking efficiency can be improved, especially when processing a large amount of viscous materials, the efficiency improvement is more obvious. It allows users to set different shaking modes according to experimental needs to meet diverse experimental conditions.

[0071] This utility model embodiment also provides a dairy product testing station, including a laboratory table and a shaking device for dairy product testing as described in any of the above embodiments, wherein the shaking device for dairy product testing is disposed on the laboratory table. Specifically, the test tube rack 1 and the rotating mechanism are disposed on the laboratory table.

[0072] Furthermore, the base 3 is fixed to the experimental table, the drive unit is fixed to the base 3, and the second rotating wheel 4 is rotatably mounted on the base 3. The test tube rack 1 is movably mounted on the base 3 via the conveyor belt 5.

[0073] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
