[0002] During the flour production process, multiple tests are required to ensure product quality and safety. For example, the protein content, ash content, etc. in the flour need to be tested, or the impurity content in the flour needs to be tested.

[0003] For example, in the patent document with application number: 202011406413.1, a flour detection device is disclosed, and specifically a device is disclosed that can filter impurities in flour samples, compare the quality of flour samples, and obtain the impurity content of flour.

[0004] In the above technical solution, since the flour particles themselves are small, there are interaction forces between the particles, including van der Waals forces and electrostatic forces, which enable the flour to adhere to each other to form a relatively stable stacking structure. At the same time, the surface tension and air resistance in the flour will also cause the flour to accumulate. Therefore, when the flour quality is tested, if the relatively fine flour cannot be tested, the impurities wrapped in the flour will be difficult to be accurately removed, affecting the detection accuracy of the flour. Summary of the Invention

[0010] A further technical improvement of the present invention is that a loading inlet for test flour is provided on the top of the shell, a bottom outlet for test flour is provided at the bottom of the shell, and a residual inlet for defective flour is provided on the inner wall of the shell.

[0011] A further technical improvement of the present invention is that the internal processing mechanism includes a guide vibration plate, the guide vibration plate is rotatably mounted inside the shell through a torsion spring, and the residual inlet is located above the guide vibration plate.

[0012] A further technical improvement of the present invention is that a bottom fixed base is slidably provided on the bottom outlet, a vibration screen is fixedly connected to the bottom fixed base via a connecting bracket, and the vibration screen cooperates with the guide vibration plate.

[0013] A further technical improvement of the present invention is that a sliding column is fixed to the side of the bottom outlet, the sliding column and the bottom fixed base are slidably connected, and vibration springs are respectively fixed to both ends of the bottom fixed base.

[0014] A further technical improvement of the present invention is that an arc-shaped guiding blanking plate is fixed to the top of the bottom fixed base, and a bottom inclined surface is fixed to the bottom of the shell.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 3. This application realizes parallel processing by rotating the outer ring to carry four shells, which sequentially pass through the loading, vibration, unloading, and defective processing stations. When a single station is processing, the other stations can operate synchronously, significantly shortening the inspection cycle. The linkage between the bottom cylinder and the mating protrusions precisely controls the lifting and lowering of the bottom fixed base, realizing the automatic separation and unloading of qualified flour and defective products, reducing manual intervention.

[0028] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0029] See also Figure 1-6As shown, the flour quality online detection device includes a rotating base 1, wherein the rotating base 1 is installed at the output end of the rotating motor, and a rotating outer ring 3 is fixedly installed on the rotating base 1, wherein a receiving and processing box 2 is installed on the rotating outer ring 3 through a mounting mechanism. In the present application, four groups of receiving and processing boxes 2 are provided, and four processing stations are provided on the rotating base 1, including a loading station 4 for loading test flour, a vibration station 5 for vibrating the receiving and processing box 2, a unloading station 6 for unloading test of the test flour, and a residual processing station 7 for unloading residual agglomerated flour, etc. In the present application, the test flour is first poured into the receiving and processing box at the loading station 4. Inside the body 2, the test flour is preliminarily processed by using the receiving and processing box 2, and then the rotating base 1 is driven by the rotating motor to rotate the receiving and processing box 2 with the test flour to the position of the vibration station 5, providing vibration force to the receiving and processing box 2, and further realizing the pretreatment of the test flour. After the treatment is completed, the receiving and processing box 2 is rotated to the position of the unloading station 6, and the treated flour is unloaded. At this time, relatively loose flour is obtained. Testing the flour can avoid the problem of flour testing accuracy being affected by flour clumping or accumulation. Finally, the receiving and processing box 2 is rotated to the position of the residual processing station 7, and the obtained agglomerated flour is unloaded separately.

[0030] As a further embodiment of the present application, first, a vibration platform is provided on the vibration station 5, which is retractable and installed at the output end of the vibration motor. When the receiving and processing box 2 is rotated to the position of the vibration station 5, the vibration platform is moved above the position of the receiving and processing box 2, and the vibration platform is driven by the vibration motor to realize the vibration of the receiving and processing box 2, thereby realizing the test flour processing inside the receiving and processing box 2.

[0031] Furthermore, in order to realize the installation of the receiving and processing box body 2, four sets of top mounting bases 28 are fixed on the rotating outer ring 3, wherein the top mounting base 28 is fixedly mounted with a rotating mounting base 23, wherein the rotating mounting base 23 is rotatably mounted with a side rotating shaft 27, wherein the side rotating shaft 27 is fixedly connected to the receiving and processing box body 2, so when in use, due to the gravity of the receiving and processing box body 2, that is, a counterweight block is installed at the bottom of the receiving and processing box body 2, the center of gravity of the receiving and processing box body 2 is relatively low, which is used to maintain the overall stability of the receiving and processing box body 2, so in this application, under the action of gravity and the center of gravity position of the receiving and processing box body 2, the receiving and processing box body 2 is always positioned vertically downward to prevent the receiving and processing box body 2 from flipping over.

[0032] Furthermore, the receiving and processing box 2 includes a shell 21, a feeding inlet 29 for allowing test flour to enter is provided at the top of the shell 21, a bottom outlet 268 for allowing test flour to be discharged is provided at the bottom of the shell 21, and an internal processing mechanism 26 for processing the test flour is provided between the feeding inlet 29 and the bottom outlet 268 of the shell 21, and a side residual placement box 22 for placing residual flour after processing is provided on the side of the shell 21, and a residual inlet 210 is provided on the side residual placement box 22, a residual outlet 25 is provided at the bottom of the side residual placement box 22, and an outlet control switch 24 for realizing discharge control is provided on the residual outlet 25, so in this application, the flour is first placed The flour is loaded from the loading inlet 29. At this time, the test flour is processed by the internal processing mechanism 26, and the processed test flour is separated. The separated test flour is discharged from the bottom outlet 268 at the bottom, and the defective flour enters the inside of the side residual placement box 22 through the residual inlet 210 for collection. When the shell 21 is transferred to the position of the residual processing station 7, the outlet control switch 24 is turned on, and the defective flour is discharged through the residual outlet 25. In this process, defective flour with larger particle size can be obtained, and large impurities can be preliminarily filtered out. At the same time, it can also ensure the detection accuracy during fine detection, such as protein content detection and trace impurity detection of flour, so that more accurate flour detection results can be obtained.

[0033] The internal processing mechanism 26 includes a guide vibration plate 261, and an internal rotating seat 262 is fixedly installed on the side of the inner wall of the shell 21, wherein the guide vibration plate 261 is rotatably installed on the internal rotating seat 262 through a torsion spring, and a bottom fixed base 267 is provided on the sliding rod on the bottom outlet 268, wherein the top of the bottom fixed base 267 is fixed with an arc-shaped guide discharge plate 269 for guiding the test flour, and at the same time, a vibration screen 263 is fixedly installed on the top of the arc-shaped guide discharge plate 269 through a connecting bracket 264, wherein the vibration screen 263 and the guide vibration plate 261 are tightly pressed. When the test flour is loaded, the test flour falls on the guide vibration plate 261, and the test flour generates a certain pressure, causing the vibration screen 263 to move downward, exerting a certain downward pressure on the bottom fixed base 267, and generating a small amount of vibration in the process, resulting in The relatively fine flour is screened and falls through the vibrating screen 263. The fallen flour is in a relatively fine state, which is convenient for retesting the flour. The accumulated flour is retained on the vibrating screen 263. When passing through the vibration station 5, the flour is fully vibrated, which makes it easy for the relatively fine flour to fall, ensuring the accuracy of the test flour during retesting. When the separation is completed, when the shell 21 reaches the position of the unloading station 6, the bottom fixed base 267 is pushed upward by external equipment. At this time, the flour falls under the action of the arc-shaped guiding unloading plate 269 and falls into the retesting equipment, ensuring the accuracy of flour batch testing. The present application is provided with four receiving and processing boxes 2, which can process and test different test flours from different batches, or process and test test flours at different production stages of the same batch, to ensure the test effect.

[0034] In order to achieve the vibration of the vibrating screen 263, the bottom fixed base 267 is slidably installed on the sliding column 2613, wherein the sliding column 2613 is provided with a vibration spring 2612, wherein the vibration spring 2612 is installed on both sides of the bottom fixed base 267, and the sliding column 2613 is fixedly installed on the shell 21. When in use, the effect of the vibration spring 2612 is utilized so that when the vibrating screen 263 suddenly receives the test flour, it generates certain vibration and shaking, which facilitates the falling of the flour and the separation of the flour accumulated in blocks.

[0035] A bottom slope 266 is fixed to the bottom of the shell 21, and an air outlet 2611 is provided on the bottom slope 266. At the same time, the air outlet 2611 is connected to the air pump through the air outlet pipe 265. The air pump is used to generate gas, and the gas is input into the interior of the shell 21 through the air outlet pipe 265. The airflow is then used to intermittently apply a certain amount of airflow to the flour on the vibrating screen 263 to reduce the possibility of its accumulation and shake it out. At the same time, the bottom slope 266 and the arc-shaped guiding discharge plate 269 are used to guide the discharge of the test flour to avoid its accumulation.

[0036] In order to push the bottom fixed base 267, a matching groove 2614 is opened at the bottom of the bottom fixed base 267, and a bottom cylinder 2616 is fixed on the frame, wherein the output end of the bottom cylinder 2616 is fixed with a matching protrusion 2615 for matching with the matching groove 2614. Therefore, when in use, the bottom cylinder 2616 is started to control the longitudinal movement of the matching protrusion 2615 until the matching protrusion 2615 moves into the inside of the matching groove 2614, until the bottom fixed base 267 is moved longitudinally to the highest end and separated from the bottom outlet 268. At this time, the bottom outlet 268 facilitates the discharge function of the test flour, and the vibrating screen 263 pushes the guide vibration plate 261 upward. At this time, the guide vibration plate 261 needs to overcome the torsion spring force until the residual flour is guided to the position of the residual inlet 210 through the guide vibration plate 261, so as to guide the residual flour to the inside of the side residual placement box 22 to realize the discharge of the residual flour.

[0037] When the present invention is in use, first, the test flour is poured into the interior of the receiving and processing box 2 at the loading station 4, and the test flour is preliminarily processed by using the receiving and processing box 2. Subsequently, the rotating motor drives the rotating base 1 to rotate the receiving and processing box 2 with the test flour to the position of the vibration station 5, and the receiving and processing box 2 is provided with a vibration force to further realize the pretreatment of the test flour. After the treatment is completed, the receiving and processing box 2 is rotated to the position of the unloading station 6, and the treated flour is unloaded. At this time, relatively loose flour is obtained, and the flour is tested, which can avoid the problem of flour testing accuracy being affected by flour agglomeration or accumulation. Finally, the receiving and processing box 2 is rotated to the position of the residual processing station 7, and the obtained agglomerated flour is unloaded separately.

[0038] When the receiving and processing box 2 is located at the vibration station 5, the vibration platform is moved above the position of the receiving and processing box 2, and the vibration motor is used to drive the vibration platform, thereby vibrating the receiving and processing box 2 to process the test flour inside the receiving and processing box 2;

[0039] During this process, due to the tight compression between the vibrating screen 263 and the guiding vibration plate 261, when the test flour is loaded, the test flour falls onto the guiding vibration plate 261. At this time, the test flour generates a certain pressure, causing the vibrating screen 263 to move downward, exerting a certain downward pressure on the bottom fixed base 267. A small amount of vibration is generated during this process, causing the relatively fine flour to be screened and fall through the vibrating screen 263. The fallen flour is in a relatively fine state, which is convenient for retesting the flour. The accumulated flour is retained on the vibrating screen 263. When passing through the vibration station 5, the flour is fully vibrated, thereby facilitating the falling of the relatively fine flour, thereby ensuring the accuracy of the retesting of the test flour.

[0040] When at the unloading station 6, the bottom cylinder 2616 is started to control the longitudinal movement of the mating protrusion 2615 until the mating protrusion 2615 moves to the inside of the mating groove 2614, until the bottom fixed base 267 is moved longitudinally to the highest end and separated from the bottom outlet 268. At this time, the bottom outlet 268 facilitates the unloading function of the test flour, and the vibrating screen 263 pushes the guide vibration plate 261 upward. At this time, the guide vibration plate 261 needs to overcome the torsion spring force until the residual flour is guided to the position of the residual inlet 210 through the guide vibration plate 261, so as to facilitate the guidance of the residual flour to the inside of the side residual placement box 22 to realize the unloading of the residual flour.
