Description

Technical Field

[0001] The present invention relates to the field of machinery, and in particular to an intelligent powder analyzer and its working method. Background Art

[0002] The particle size and water content of the powder will have a relatively large impact on the quality of the finished product. For example, in the ceramic production process, if the particles of the ceramic powder are too large or uneven, it may cause uneven cloth spreading, and then lead to the possibility of cracking near the large particles. Another example is that if the water content of the ceramic powder is too high, it may cause the ceramic to have interlayers.

[0003] In the prior art, generally, manual sampling of the powder is used to analyze the powder. Specifically, workers take some powder from the powder conveyor belt, and then send the powder to the laboratory for chemical analysis. After obtaining the analysis data, the data is fed back. The entire sampling and analysis process of the powder is not only time-consuming and laborious, but also prone to untimely feedback, resulting in missing the best opportunity to adjust the powder.

[0004] Therefore, in view of the above situation, how to improve the existing powder analysis technology, such as analysis methods or equipment, so as to solve the above problems has become an important technical problem that needs to be solved urgently by those skilled in the art.

Through the settings of the material taking mechanism, moisture detection mechanism, hopper mechanism, conveyor belt mechanism and shooting mechanism, it can not only realize the full-automatic intelligent analysis of powder at a fixed time and frequency, but also send it to the user in time, so that the user can adjust the powder in time, thus solving the problems existing in the prior art.

[0068] The following will clearly and detailedly describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. Please refer to Figures 1 to 10 , which is an intelligent powder analyzer of the present invention, installed near the powder conveyor belt, and includes a frame 1, and a material taking mechanism 2, a moisture detection mechanism 3, a hopper mechanism 4, a conveyor belt mechanism 5 and a shooting mechanism 6 arranged in the frame 1;

[0069] The material taking mechanism 2 is arranged above the powder conveyor belt and is used to grab powder from the powder conveyor belt and transport it to the hopper mechanism 4;

[0070] The moisture detection mechanism 3 includes a moisture detector assembly 31 and a weighing assembly 32, wherein the moisture detector assembly 31 is arranged on the material taking mechanism 2 and is used to detect the moisture content of the powder in the hopper mechanism 4;

[0071] The conveyor belt mechanism 5 includes an upper conveyor belt 51 and a lower conveyor belt 52. The upper conveyor belt 51 is provided with a scraper 511 for scraping the powder falling from the hopper mechanism 4. The lower conveyor belt 52 is arranged below the upper conveyor belt 51 and the discharge end of the upper conveyor belt 51 is directly above the feed end of the lower conveyor belt 52.

[0072] The weighing assembly 32 is fixed on the frame 1 and above the upper conveyor belt 51. The hopper mechanism 4 is provided above the weighing assembly 32 and is used to weigh the entire hopper mechanism 4.

[0073] The photographing mechanism 6 is disposed above the lower conveyor belt 52 and is used to photograph the particle size of the powder on the lower conveyor belt 52 .

[0074] In an embodiment of the present invention, the intelligent powder analyzer is installed near the powder conveyor belt. Specifically, the intelligent powder analyzer can be installed above the powder conveyor belt. For example, the powder conveyor belt passes through the frame 1 and is located below the material taking mechanism 2, the moisture detection mechanism 3, the hopper mechanism 4, the conveyor belt mechanism 5 and the shooting mechanism 6. During operation, the material taking mechanism 2 starts and grabs the powder from the powder conveyor belt and conveys it to the hopper mechanism 4. After the powder falls into the hopper mechanism 4, the hopper mechanism 4 will process the powder and ensure that the volume of the powder before each water and powder test is the same; then the moisture detector component 31 and the weighing component 32 in the moisture detection mechanism 3 respectively detect the moisture of the powder in the hopper mechanism 4. It should be noted here that the moisture detector component 31 uses a direct detection method to detect the moisture of the powder, and the weighing component 32 weighs the entire hopper mechanism 4. The weight of the powder can be obtained by calculation, and then the moisture content of the powder can be calculated. The moisture content data of the powder can be obtained after the double detection of the moisture detector component 31 and the weighing component 32; then The powder falls from the hopper mechanism 4 to the upper conveyor belt 51. Since a scraper plate 511 is provided on the upper conveyor belt 51, the scraper plate 511 flattens the powder on the upper conveyor belt 51 and conveys it to the lower conveyor belt 52. By adjusting the rotation speed of the upper conveyor belt 51 and the lower conveyor belt 52, the powder on the lower conveyor belt 52 can be placed in a flat state; finally, the shooting mechanism 6 shoots the powder on the lower conveyor belt 52 and performs image analysis on the shot image to obtain the particle size data of the powder; according to the moisture content data and particle size data of the powder, the intelligent analysis of the powder can be completed. At this time, the powder analysis results can be obtained and sent to a preset location, for example, by wired or wireless means, specifically by 5G communication.

[0094] In an embodiment of the present invention, the moisture detector assembly 31 can move above the hopper mechanism 4 following the movement of the moving plate 232. At this time, the double-rod cylinder 311 works and lowers the moisture detector 312 until the probe of the moisture detector 312 is inserted into the powder in the hopper mechanism 4, and the moisture detector 312 completes the moisture detection of the powder in the hopper mechanism 4. The weighing assembly 32 includes two symmetrically arranged weighing sensors, which measure the weight of the hopper mechanism 4 together with the powder. By knowing the weight of the hopper mechanism 4 in advance, the weight of the powder can be obtained, and then the moisture content data of the powder can be obtained through calculation.

[0115] The embodiments of the intelligent powder analyzer of the present invention are described above. Next, the embodiments of the working method of the intelligent powder analyzer of the present invention are described, which are used in the above intelligent powder analyzer. Please refer to Figure 11 , including:

[0116] S1: Grab the powder from the powder conveyor belt according to the set time frequency and transport it to the hopper mechanism;

[0117] According to the actual production requirements, the frequency of grabbing the powder from the powder conveyor belt, that is, the frequency of powder analysis, can be specifically set to grab the powder for analysis once an hour, which is not limited here. After grabbing the powder, the powder can be transported to the hopper mechanism.

[0118] S2: Insert the moisture detector assembly into the hopper mechanism and measure the moisture of the powder to obtain the first moisture data;

[0119] After the hopper mechanism receives the powder, the moisture detector assembly will be inserted into the powder to measure the moisture of the powder, and at this time, the first moisture data can be obtained.

[0120] S3: Instruct the hopper mechanism to work and push the powder in it to a set powder volume value, weigh the hopper mechanism, and calculate to obtain the second moisture data;

[0121] When using the weighing method to calculate the moisture data of the powder, it is necessary to ensure that the volume of the powder measured each time is the same. Therefore, first, the powder needs to be leveled by the hopper mechanism. At this time, the volume of the powder is the volume of the powder mechanism. The moisture data of the powder is obtained through the calculation interface, which is the second moisture data.

[0122] It should be noted that the order of steps S2 and S3 is not sequential, that is, step S3 can be executed first and then step S2, which is not limited here.

[0123] S4: Obtain the powder moisture content value through the first moisture data and the second moisture data;

[0124] After obtaining the first moisture data and the second moisture data, the powder moisture content value can be obtained by using the set calculation method. The above calculation methods can be: 1. Directly take the average value of the first moisture data and the second moisture data, which is the powder moisture content value; 2. Use the weighted average method for calculation. Specifically, set the weight value of the first moisture data as a and the weight value of the second moisture data as b, then the powder moisture content value = a * the first moisture data + b * the second moisture data. It should be noted that the above two methods are only two of the listed calculation methods, and it does not mean that only the above two methods can be used to calculate the powder moisture content value.

[0125] S5: Level the powder from the hopper mechanism and convey it to below the imaging mechanism by the conveyor belt mechanism;

[0126] After obtaining the moisture content value of the powder, the powder falls from the hopper mechanism to the conveyor belt mechanism, and the scraper on the conveyor belt mechanism levels the powder to facilitate subsequent imaging of the powder by the imaging mechanism.

[0127] S6: Image the powder and obtain powder particle data;

[0128] The imaging mechanism continuously takes pictures of the powder from the conveyor belt mechanism, and the powder particle data can be obtained by performing image analysis on the taken pictures.

[0129] S7: Obtain a powder analysis result based on the powder moisture content value and the powder particle data;

[0130] Analyze and compare the powder moisture content value and the powder particle data to obtain the powder analysis result. The specific powder analysis result above can be: the powder moisture content value is lower than 10% of the standard value, and the powder particle diameter is too large; according to the above powder analysis result, water needs to be injected into the powder to reach the standard value.

[0131] S8: Send the powder analysis result to a set position;

[0132] After obtaining the powder analysis result, it can be sent to a set position. For example, it can be sent to the mobile phone of the monitoring personnel, which is not limited here. The above sending to the set position can send the powder analysis result to the set position through wireless or wired communication. Specifically, it can be sent through 5G communication.

[0133] Through the dual detection of the first moisture data and the second moisture data, and using the imaging mechanism to analyze the particle size of the powder, the working method of the intelligent powder analyzer of the present invention can not only realize the full-automatic intelligent analysis of the powder at a fixed time and frequency, but also send it to the user in time, and the user can adjust the powder in time, thus solving the problems existing in the prior art.

[0134] Those of ordinary skill in the art can understand that all or part of the steps in the above method embodiments can be completed by instructing relevant hardware through a program, and the program can be stored in a computer-readable storage medium. The above-mentioned storage medium can be a read-only memory, a disk or an optical disc, etc.

[0135] The above has introduced the intelligent powder analyzer and its working method provided by the present invention in detail. For those of ordinary skill in the art, according to the idea of the embodiments of the present invention, there will be changes in the specific implementation manners and application scopes. In summary, the content of this specification should not be construed as a limitation to the present invention.
