Description

Technical Field

[0001] This utility model relates to the field of oil testing technology, and in particular to an oil content testing device for tofu skin. Background Technology

[0002] In the process of tofu skin production, in order to detect and determine whether the product meets the corresponding standard requirements and ensure quality stability, near-infrared spectroscopy analysis technology is required for rapid and non-destructive testing. When using a near-infrared spectroscopy analyzer to detect the oil content of tofu skin, the broken tofu skin sample needs to be placed in the sample cell, and the sample cell is rotated to ensure that the near-infrared light irradiates the sample evenly.

[0003] However, in existing near-infrared spectrometers, the top of the sample cell is always open during use. When the sample cell rotates, the tofu skin, being relatively light, is easily splashed out due to centrifugal force and other factors. This not only causes sample loss but may also contaminate the instrument, affecting the detection environment and the accuracy of subsequent test results. To address these issues, we propose a tofu skin oil content testing device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device for testing the oil content of tofu skin.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A device for testing the oil content of tofu skin includes a near-infrared spectrometer. A positioning ring is fixedly connected to the top of the near-infrared spectrometer, and a sample chamber is inserted inside the positioning ring. A first support plate is fixedly connected to the top of the near-infrared spectrometer, and a protective plate is placed on the upper side of the first support plate. A linkage block is fixedly connected to one side of the bottom end of the protective plate. A groove is formed on the top of the first support plate, and a connecting shaft is fixedly connected to the inner wall of the groove. The linkage block is movably sleeved on the outside of the connecting shaft. The other side of the bottom end of the protective plate abuts against a second support plate, and the bottom end of the second support plate is fixedly connected to the near-infrared spectrometer.

[0006] Preferably, a torsion spring is fixedly connected to the side of the linkage block, and the other end of the torsion spring is fixedly connected to the inner wall of the groove.

[0007] Preferably, a rubber column is fixedly connected to the bottom end of the protective plate, and an insertion groove adapted to the rubber column is provided on the top of the second support plate.

[0008] Preferably, the protective plate is fixedly connected to the side of the protective plate, and the outer surface of the protruding plate is provided with anti-slip texture.

[0009] Preferably, a threaded rod is inserted inside the protective plate, and the bottom of the threaded rod is connected to the pressure plate through a bearing, and a connecting cap is fixedly connected to the top of the threaded rod.

[0010] Preferably, a connecting rod is vertically connected to the top of the pressure plate, and the interior of the protective plate has holes that are compatible with the connecting rod.

[0011] Preferably, the outer wall of the pressure plate is uniformly provided with holes, and the inner wall of each hole is provided with ball bearings.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The device is equipped with a first support plate and a protective plate. During the rotation and detection of the sample chamber, the protective plate located on the upper side can block the sample, avoid the problem of sample splashing and displacement caused by centrifugal force, prevent sample loss, and prevent the instrument from being contaminated.

[0013] 2. This device is equipped with a threaded rod and a pressure plate. Before testing, the operator can rotate the threaded rod to drive the pressure plate downward, thereby pressing the upper surface of the sample into a flat plane. This makes the reflection and absorption of near-infrared light on the sample surface more uniform, significantly improving the accuracy and stability of oil content detection.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figure 1-4 A device for testing the oil content of tofu skin includes a near-infrared spectrometer 1. A positioning ring 2 is fixedly connected to the top of the near-infrared spectrometer 1, and a sample chamber 3 is inserted inside the positioning ring 2. A first support plate 4 is fixedly connected to the top of the near-infrared spectrometer 1, and a protective plate 5 is placed on the upper side of the first support plate 4. A linkage block 6 is fixedly connected to one side of the bottom of the protective plate 5. A groove is formed on the top of the first support plate 4, and a connecting shaft 7 is fixedly connected to the inner wall of the groove. The linkage block 6 is movably sleeved on the outside of the connecting shaft 7. The bottom of the protective plate 5... The other side abuts against the second support plate 9, and the bottom end of the second support plate 9 is fixedly connected to the near-infrared spectrometer 1. The second support plate 9 can support the protective plate 5. The linkage block 6 and the connecting shaft 7 can meet the requirements for the angular rotation of the protective plate 5. The bottom of the sample chamber 3 is an optical window made of quartz glass with high near-infrared light transmittance, which ensures that the near-infrared beam irradiates the sample inside the sample chamber 3. In addition, the sample chamber 3 can be rotated by the drive component inside the near-infrared spectrometer 1 to achieve accurate detection of the sample.

[0018] Furthermore, refer to Figure 2 and Figure 4 It can be seen that the side of the linkage block 6 is fixedly connected with a torsion spring 8, and the other end of the torsion spring 8 is fixedly connected to the inner wall of the groove. During use, the setting of the torsion spring 8 can ensure the tightness and reliability of the protective plate 5 covering the sample chamber 3.

[0019] Furthermore, refer to Figure 4 It can be seen that the bottom end of the protective plate 5 is fixedly connected to a rubber column 10, and the top of the second support plate 9 is provided with a plug groove that is compatible with the rubber column 10. Through the interference fit between the rubber column 10 and the plug groove, the protective plate 5 can be effectively prevented from being opened accidentally.

[0020] Furthermore, refer to Figure 1 and Figure 4 It can be seen that the protective plate 5 is fixedly connected to the side of the protruding plate 16, and the outer surface of the protruding plate 16 is provided with anti-slip texture. With the cooperation of the protruding plate 16 and the anti-slip texture, it is easy for the staff to lift the protective plate 5 so that the staff can take the sample chamber 3 out from the top of the positioning ring 2.

[0021] Furthermore, refer to Figure 3 and Figure 4It can be seen that a threaded rod 11 is inserted inside the protective plate 5, and the bottom of the threaded rod 11 is connected to the pressure plate 14 through a bearing. A connecting cap 13 is fixedly connected to the top of the threaded rod 11. The protective plate 5 has a threaded groove that matches the threaded rod 11 to meet the up and down movement requirements of the pressure plate 14. The connection of the connecting cap 13 allows the staff to easily and effortlessly rotate the threaded rod 11.

[0022] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the top of the pressure plate 14 is vertically connected to the connecting rod 12, and the inside of the protective plate 5 is provided with holes that are compatible with the connecting rod 12. During use, the vertical guidance of the pressure plate 14 can be achieved through the holes and the connecting rod 12.

[0023] Furthermore, refer to Figure 3 It can be seen that the outer wall of the pressure plate 14 is evenly provided with holes, and the inner wall of each hole is provided with ball bearings 15. By setting multiple sets of ball bearings 15, hard friction between the outer wall of the pressure plate 14 and the inner wall of the sample chamber 3 can be prevented, so as to ensure the normal rotation of the sample chamber 3.

[0024] Working Principle: When using this utility model, the operator can first place the device in a suitable position on the table and place the crushed tofu skin sample into the sample chamber 3. Then, the operator can manually pull the protruding plate 16, causing it to rotate the protective plate 5 simultaneously. This causes the linkage block 6 connected to the bottom of the protective plate 5 to slide along the outer surface of the connecting shaft 7, so that the protective plate 5 is no longer above the positioning ring 2. At this time, the operator can put the sample chamber 3 into the interior of the positioning ring 2. After the insertion is completed, the operator can stop pulling the protective plate 5, so that the protective plate 5 resets and covers the positioning ring 2 and the sample chamber 3 again. Then, the operator can manually rotate the connecting cap 13, causing the threaded rod 11 to rotate simultaneously. This pushes the pressure plate 14 into the sample chamber 3, so as to achieve the flat operation of the sample inside the sample chamber 3. When the driving component inside the near-infrared spectrometer 1 drives the sample chamber 3 to rotate for detection, the setting of the pressure plate 14 and the protective plate 5 can prevent the sample from splashing. The above is the complete working principle of this utility model.

As long as they can achieve their beneficial effects, they can be implemented, so they will not be described in detail.
