Description

Technical Field

[0001] This utility model relates to the field of food testing technology, and in particular to a test bench for analyzing and determining food additives. Background Technology

[0002] Food additives are substances added to food to improve its quality, color, flavor, and for preservation and processing purposes. They play a crucial role in the modern food industry. The rational use of food additives can effectively extend the shelf life of food, prevent spoilage, and enhance its taste and appearance, meeting diverse consumer demands. However, excessive or improper use can have negative effects on human health, such as increasing the risk of chronic diseases and affecting children's growth and development. Therefore, it is necessary to use food additive testing equipment to detect additives.

[0003] Currently, existing food additive testing stations typically use test tubes to hold food samples and add a suitable amount of reaction solution to the tubes to detect food additives. However, in existing technology, testing personnel usually hold the test tubes by hand and add the reaction solution using a dropper. When holding large test tubes, the operation is quite strenuous, and the tubes are prone to shaking or even accidental dropping and damage. Leakage is also common when adding reaction solution to the test tubes. Furthermore, existing test tube racks have fixed specifications, making it difficult to position and place test tubes of different sizes.

[0004] Therefore, it is necessary to provide a testing bench for analyzing and determining food additives to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a testing bench for analyzing and determining food additives, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following solution to the aforementioned technical problems: a food additive analysis and determination test bench, comprising a workbench, wherein multiple ring-shaped support rods are fixed on the top side of the workbench, and a clamp is fixed at the top of the multiple support rods, wherein a cavity is provided inside the clamp, and a spinning assembly communicating with the cavity is provided outside the clamp, and a point clamp assembly for multi-point clamping and limiting of test tubes is provided inside the clamp, and multiple ring-shaped support rods are fixed at the bottom of the workbench.

[0007] As a further embodiment of this utility model, the spinning assembly includes a sleeve fixed to the inner ring sidewall of the clamp and extending through the inner ring sidewall into the cavity. Both ends of the sleeve are open. Multiple sleeves are provided and arranged in a ring. An inner tube is inserted into the sleeve and arranged coaxially with the sleeve. One end of the inner tube is fixed to a second piston plate that fits tightly against the inner sidewall of the sleeve.

[0008] As a further embodiment of this utility model, an outer sleeve communicating with the cavity is fixed on the outer wall of the clamp, and a nut sleeve is fixed inside the end of the outer sleeve away from the clamp. A threaded rod inserted into the outer sleeve is threadedly connected to the nut sleeve, and a first piston plate that fits tightly against the inner side wall of the outer sleeve is fixed on the end of the threaded rod inside the outer sleeve.

[0009] As a further embodiment of this utility model, the clamping assembly includes a slide rod inserted inside the inner tube, and a spring located on the side of the slide rod near the second piston plate is provided inside the inner tube.

[0010] As a further embodiment of this utility model, two symmetrically distributed protrusions are fixed on one end of the slide rod near the second piston plate, and a guide groove is provided on the side of the inner tube, which is arranged along the length of the inner tube and is adapted to slide with the protrusions.

[0011] As a further embodiment of this utility model, a rubber block is fixed to one end of the slide rod near the center of the clamp.

[0012] As a further embodiment of this utility model, a handle is fixed to one end of the threaded rod located outside the outer cylinder, and a rubber pad is fixed to the center of the top side of the workbench.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] A certain amount of liquid is forced into the cavity by a spinning assembly, creating hydraulic pressure inside the cavity. This hydraulic pressure then drives multiple sets of clamping components to extend synchronously, clamping and limiting the test tube inserted into the clamping seat at multiple points. This effectively improves the stability of the test tube and eliminates the need for manual handling of the test tubes for liquid addition, saving manpower and facilitating liquid addition. When the test tube contains food ingredients, a suitable reaction solution is added to detect and analyze additives. This prevents the test tube from shaking or shifting during food additive testing, thus avoiding damage due to slippage. The multi-point clamping method of the clamping components allows for clamping and positioning of test tubes of different sizes and shapes, effectively increasing the applicability and practicality of the overall device. Furthermore, the elastic clamping of the test tube sidewalls by the clamping components greatly reduces the risk of test tube breakage. Attached Figure Description

[0024] The present invention will be further described below with reference to the embodiments.

[0025] Please see Figure 1-6This utility model provides a food additive analysis and determination test bench, including a workbench 6. Multiple ring-shaped support rods 5 are fixed to the top side of the workbench 6. A clamping seat 3 is fixed to the top of the multiple support rods 5. A cavity 9 is formed inside the clamping seat 3. A spinning assembly 1 communicating with the cavity 9 is provided outside the clamping seat 3. A point clamping assembly 2 for multi-point clamping and limiting of test tubes is provided inside the clamping seat 3. Multiple ring-shaped support rods 7 are fixed to the bottom of the workbench 6. In use, the test tube is inserted into the clamping seat 3 with the test tube end facing upwards. By rotating the input end of the spinning assembly 1, a certain amount of liquid is squeezed into the cavity 9, creating hydraulic pressure inside the cavity 9. This hydraulic pressure then pushes the multiple point clamping assemblies 2 to extend synchronously. The device uses multiple clamping components 2 to clamp and limit the test tube inserted into the clamping seat 3 at multiple points, effectively improving the stability of the test tube and eliminating the need for manual handling of the test tube for adding liquid. This saves manpower and facilitates the addition of liquid to the test tube. When the test tube contains food ingredients, a suitable reaction solution is added to the test tube to detect and analyze additives. This avoids the test tube shaking or shifting position during the detection of food additives, preventing the test tube from slipping and being damaged. The multi-point clamping method of the clamping components 2 allows for clamping and positioning of test tubes of different sizes and shapes, effectively improving the applicability and practicality of the overall device. At the same time, the clamping components 2 provide elastic clamping to the side wall of the test tube, greatly reducing the risk of test tube breakage.

[0026] Further as Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, it is worth noting that the spinning assembly 1 includes a sleeve 106 fixed to the inner ring sidewall of the clamp 3 and extending through the inner ring sidewall of the clamp 3 into the cavity 9. Both ends of the sleeve 106 are open. Multiple sleeves 106 are provided and arranged in a ring. An inner tube 108 is inserted into the sleeve 106 and arranged coaxially with the sleeve 106. One end of the inner tube 108 is fixed to a second piston plate 107 that fits tightly against the inner sidewall of the sleeve 106. An outer tube 101 communicating with the cavity 9 is fixed on the outer sidewall of the clamp 3. A nut sleeve 102 is fixed inside the outer tube 101 away from the clamp 3. A threaded rod 104 inserted inside the outer tube 101 is threadedly connected to the nut sleeve 102. The threaded rod 104 is located at one end inside the outer tube 101. A first piston plate 103 is fixedly fitted to the inner wall of the outer tube 101. In specific operation, both the outer tube 101 and the cavity 9 are filled with a certain amount of liquid, such as water or hydraulic oil. By rotating the threaded rod 104, the threaded rod 104 drives the first piston plate 103 to move towards the clamping seat 3 inside the outer tube 101. Thus, the liquid inside the outer tube 101 is squeezed into the cavity 9 through the first piston plate 103, so that the cavity 9 has a certain hydraulic pressure. This hydraulic pressure drives multiple second piston plates 107 to move synchronously in the sleeve 106. The second piston plates 107 drive the inner tube 108 to move synchronously. In turn, the multiple inner tubes 108 synchronously drive multiple sets of point clamping assemblies 2 to extend synchronously and clamp and position the test tube at multiple points.

[0027] Further as Figure 3 , Figure 4 and Figure 6 As shown, it is worth noting that the clamping assembly 2 includes a slide rod 204 inserted inside the inner tube 108. A spring 201 is provided inside the inner tube 108 on the side of the slide rod 204 near the second piston plate 107. In specific operation, when the inner tube 108 moves out of the sleeve 106, the inner tube 108 drives the slide rod 204 to move out synchronously and the end of the slide rod 204 contacts the outer wall of the test tube. The spring 201 allows the slide rod 204 to elastically retract into the inner tube 108, thereby enabling multiple slide rods 204 to perform multi-point elastic clamping and limiting on the outer wall of the test tube.

[0028] Further as Figure 6 As shown, it is worth noting that two symmetrically distributed protrusions 202 are fixed on the end of the slide rod 204 near the second piston plate 107. A guide groove 203 is provided on the side of the inner tube 108, which is arranged along the length of the inner tube 108 and is slidably adapted to the protrusions 202. In actual operation, the movement of the slide rod 204 is guided and limited by the cooperation of the protrusions 202 and the guide groove 203, thereby improving the smoothness of the movement of the slide rod 204.

[0029] The working process of this solution is as follows: The test tube is inserted into the clamp 3 with the test tube end facing upward. By rotating the threaded rod 104, the threaded rod 104 drives the first piston plate 103 to move towards the clamp 3 inside the outer cylinder 101. The first piston plate 103 squeezes the liquid inside the outer cylinder 101 into the cavity 9, so that the cavity 9 has a certain hydraulic pressure. The hydraulic pressure drives multiple second piston plates 107 to move synchronously in the sleeve 106. The second piston plates 107 push the inner tube 108 to move synchronously. When the inner tube 108 moves out of the sleeve 106, the inner tube 108 drives the slide rod 204 to move out synchronously and the end of the slide rod 204 contacts the outer wall of the test tube. The spring 201 makes the slide rod 204 elastically retract into the inner tube 108, so that the ends of multiple slide rods 204 elastically clamp and limit the outer wall of the test tube at multiple points.

[0030] Further as Figure 6 As shown, it is worth noting that a rubber block 205 is fixed on one end of the slide rod 204 near the center of the clamp 3; during operation, the rubber block 205 increases the contact friction between the end of the slide rod 204 and the outer wall of the test tube.

[0031] Further as Figure 5 As shown, it is worth noting that a handle rod 105 is fixed on one end of the threaded rod 104 located outside the outer sleeve 101, and a rubber pad 8 is fixed to the center of the top side of the workbench 6; in actual operation, the threaded rod 104 can be easily rotated by the handle rod 105, which facilitates operation.

[0032] In summary: By using the spinning assembly 1 to squeeze a certain amount of liquid into the cavity 9, the cavity 9 becomes hydraulically pressurized. This hydraulic pressure drives multiple sets of clamping assemblies 2 to extend synchronously, thereby clamping and limiting the test tube inserted into the clamping seat 3 at multiple points. This effectively improves the stability of the test tube and eliminates the need for manual handling of the test tubes for dripping liquid, saving manpower and facilitating the dripping process. When the test tube contains food ingredients, adding a suitable reaction solution to the test tube for additive detection and analysis avoids the test tube shaking or shifting position during food additive testing, preventing slippage and damage. The multi-point clamping method of the clamping assemblies 2 allows for clamping and positioning of test tubes of different sizes and shapes, effectively improving the applicability and practicality of the overall device. At the same time, the elastic clamping of the test tube sidewalls by the clamping assemblies 2 greatly reduces the risk of test tube breakage.
