Description

Technical Field

[0001] This utility model relates to the field of food testing, and in particular to a microbial testing and sampling device for dairy processing. Background Technology

[0002] Dairy processing refers to the process of turning raw milk into various dairy products through a series of treatments and processing techniques. During dairy processing, it is usually necessary to collect a small number of representative samples from raw milk, intermediate products, finished products, and related objects such as equipment and environment that come into contact with dairy products, in accordance with certain methods and standards, so as to conduct microbiological analysis and testing to ensure product safety.

[0003] During sampling, staff will select appropriate samplers according to sampling needs, and then sample samples from different depths one by one according to testing requirements. By comparing the samples from different depths, the accuracy of the test results is ensured.

[0004] The existing technology has the following drawbacks: In some existing devices, the sampler has a single function. When sampling samples at different depths is required, the staff needs to operate them one by one, and they cannot be done simultaneously. The operation steps are cumbersome, time-consuming and labor-intensive. Furthermore, for different sampling needs, it is necessary to change samplers of different volumes, which is also time-consuming and labor-intensive. Therefore, a microbial detection sampling device for dairy processing is proposed to solve the above problems. Utility Model Content

[0035] Reference Figures 1-3 This utility model provides an embodiment of a microbial detection sampling device for dairy processing, comprising a sampling tube 1, a pressing rod 2 movably connected to the inner wall of the sampling tube 1, a slot corresponding to the pressing rod 2 on the sampling tube 1 to ensure that the pressing rod 2 is not obstructed during vertical movement and rotation, a rotating block 3 rotatably connected to the bottom end of the pressing rod 2, a slot corresponding to the rotating block 3 on the pressing rod 2 to facilitate rotation of the pressing rod 2, the bottom end of the rotating block 3 being elastically connected to the sampling tube 1 via a movable spring 4, and a long rod 5 slidably connected to the lower surface of the pressing rod 2, the pressing rod 2 having an arc-shaped... The slot will not obstruct the rotation of the pressing rod 2. The outer wall of the long rod 5 is fixedly connected to the opening and closing plate 6. The sampling tube 1 is provided with multiple sets of openings, which are slightly smaller than the opening and closing plate 6. In the initial state, the opening and closing plate 6 blocks the openings on the sampling tube 1. The inner wall of the pressing rod 2 is provided with a limit mechanism. The inner wall of the sampling tube 1 is provided with an adjustment component. The limit mechanism includes an arc-shaped block 8. The right side wall of the arc-shaped block 8 is elastically connected to the pressing rod 2 through a moving spring 7. The arc-shaped block 8 is slidably connected to the inner wall of the pressing rod 2. The pressing rod 2 is provided with a slot corresponding to the arc-shaped block 8, allowing the arc-shaped block 8 to move left and right.

[0036] Reference Figure 1 , Figure 4 and Figure 5 The adjustment assembly includes a movable rod 9, with a circular piece 10 fixedly connected to its outer wall. A plug 11 is inserted into the inner wall of the movable rod 9. The movable rod 9 has multiple slots corresponding to the plug 11. Initially, the plug 11 is inserted into the slots. The outer wall of the plug 11 is elastically connected to the sampling tube 1 via a positioning spring 12. The movable rod 9 passes through and is slidably connected to the inner wall of the sampling tube 1. The sampling tube 1 has slots corresponding to the movable rod 9, allowing the movable rod 9 to move vertically. The plug 11 is slidably connected to the top of the sampling tube 1. The sampling tube 1 has a slot corresponding to the insert 11, allowing the insert 11 to move back and forth. The disc 10 is slidably connected to the inner wall of the sampling tube 1. The sampling tube 1 has a slot corresponding to the disc 10, allowing the disc 10 to move vertically. The outer wall of the insert 11 is fixedly connected to one end of the positioning spring 12, and the other end of the positioning spring 12 is fixedly connected to the inner wall of the rear end of the sampling tube 1. When the insert 11 moves backward, the positioning spring 12 is compressed. When resetting, the elastic force of the positioning spring 12 is used to reset the insert 11.

[0037] Reference Figure 1 , Figure 6 and Figure 7The right sidewall of the arc-shaped block 8 is fixedly connected to one end of the moving spring 7, and the other end of the moving spring 7 is fixedly connected to the inner wall of the right end of the pressing rod 2. Initially, the sampling tube 1 blocks the arc-shaped block 8, and the moving spring 7 is initially in a compressed state. When the sampling tube 1 no longer blocks the arc-shaped block 8, the arc-shaped block 8 pops out under the elastic force of the moving spring 7. At this time, the moving spring 7 is in a reset state. The long rod 5 passes through and is slidably connected to the inner wall of the sampling tube 1. The sampling tube 1 has a slot corresponding to the long rod 5, allowing the long rod 5 to move vertically. The opening and closing plate 6 is slidably connected to the inner wall of the sampling tube 1, and the sampling tube 1 has a slot corresponding to the opening and closing plate 6. The slot allows the opening and closing plate 6 to move vertically. The arc-shaped block 8 is inserted into the inner wall of the sampling tube 1. The sampling tube 1 has a slot corresponding to the arc-shaped block 8. The slot and the long rod 5 are in the same horizontal direction. The bottom end of the rotating block 3 is fixedly connected to one end of the movable spring 4. The other end of the movable spring 4 is fixedly connected to the top inner wall of the sampling tube 1. When the rotating block 3 moves downward, the movable spring 4 is compressed. When resetting, the elastic force of the movable spring 4 is used to reset the rotating block 3. The rotating block 3 is slidably connected to the inner wall of the sampling tube 1. The sampling tube 1 has a slot corresponding to the rotating block 3, allowing the rotating block 3 to move vertically.

[0038] Working principle: When sampling is required, the sampling tube 1 is placed in the milk product. Then, the hand moves the pressing rod 2 downwards. The pressing rod 2 moves the rotating block 3, the arc-shaped block 8, the long rod 5, and the opening / closing plate 6 downwards. The rotating block 3 compresses the movable spring 4. As the three sets of opening / closing plates 6 move downwards, they no longer block the opening on the sampling tube 1, allowing samples at different depths to flow into the sampling tube 1. Next, the hand rotates the pressing rod 2 counterclockwise. When the pressing rod 2, along with the arc-shaped block 8, aligns with the groove on the sampling tube 1, under the elastic force of the movable spring 7, it inserts the arc-shaped block 8 into the groove of the sampling tube 1, completing the process. The pair of opening and closing plates 6 limit the movement of the sample tube 1. When the sample tube 1 is full of sample, the hand rotates the pressing rod 2 clockwise. The pressing rod 2 will rotate the arc-shaped block 8. At this time, the slot on the sample tube 1 will squeeze the arc-shaped block 8, allowing the arc-shaped block 8 to enter the pressing rod 2. The arc-shaped block 8 will squeeze the moving spring 7. Then, the hand rotates the pressing rod 2 to the initial position and releases it. The elastic force of the movable spring 4 will move the rotating block 3 upward. The rotating block 3 will move the pressing rod 2, the long rod 5 and the opening and closing plates 6 to the initial position. The opening and closing plates 6 will block the slot on the sample tube 1. If sampling is required again, simply repeat the above operation steps.

[0039] When the sampling capacity needs to be adjusted, move the insert 11 backward with your hand. The insert 11 will compress the positioning spring 12. When the insert 11 separates from the slot on the movable rod 9, you can move the movable rod 9 vertically with your hand. The movable rod 9 will move the disc 10 vertically. Use the gap between the disc 10 and the sampling tube 1 to adjust the sampling capacity. When the adjustment is complete, the insert 11 will coincide with the slot on the movable rod 9. Release the insert 11 with your hand, and use the elasticity of the positioning spring 12 to insert the insert 11 into the slot of the movable rod 9 to complete the limiting of the disc 10. If you need to adjust the sampling capacity again, just repeat the above operation steps.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
