Description

Technical Field

[0001] The present invention relates to the fields of traditional Chinese medicine health food processing equipment and laser measurement technology, and in particular to a system and method for preparing deer antler powder based on laser measurement. Background Art

[0002] Currently, the traditional deer antler powder production process lacks precise and effective methods for particle size control and screening. Existing screening equipment often uses simple mechanical screening methods, making it difficult to achieve multi-stage precision screening. This results in uneven particle size distribution and fails to meet the stringent particle size requirements of different applications. Furthermore, the lack of real-time particle size measurement and feedback mechanisms during the screening and preparation process prevents timely adjustments and optimization of the production process, leading to material waste and low production efficiency. Furthermore, the poor interoperability between components in traditional systems makes automated and intelligent production control difficult, hindering the high-quality development of the deer antler powder production industry. Specifically, the traditional deer antler powder production process suffers from inaccurate particle size screening and the difficulty of achieving multi-stage screening. The lack of real-time particle size measurement and feedback mechanisms also leads to uneven particle size distribution. Traditionally, deer antler powder screening relies on single or simple screens with fixed mesh sizes, which fail to achieve step-by-step separation based on particle size. This results in a mixture of large, medium, and small particles, making it difficult to meet the differentiated particle size requirements of different applications. Particle size testing is delayed or missing, making it impossible to ensure consistent product quality. In traditional processes, antler powder particle size testing is often performed using offline sampling, which is subject to lags and makes it difficult to monitor particle size fluctuations during production in real time. This can easily lead to the mass production of substandard products or their mixing with qualified products, impacting final quality. Substandard products are difficult to quickly remove, leading to quality risks. In traditional production processes, even if antler powder with substandard particle size is discovered, it is difficult to separate it promptly during the production process, which can easily result in substandard and qualified products being mixed together, increasing subsequent sorting costs or directly impacting product quality. Traditional antler powder grading requires manual sorting and barreling. This is not only labor-intensive but also prone to human error, leading to the mixing of antler powders of different particle sizes, impacting the accuracy and consistency of product grading. The screening and measurement processes lack synergy, making it impossible to dynamically optimize production parameters. In traditional processes, screening, measurement, and barreling are independent and lack coordinated control. When particle size fluctuates, production parameters such as screening intensity and feed rate cannot be adjusted promptly, resulting in reduced production efficiency and material waste. The degree of automation is low, it relies on manual operation and has poor stability. In the traditional preparation process, screening, feeding, testing, barreling and other links mostly rely on manual intervention. Not only is the labor intensity high, but the randomness of manual operation can easily lead to an unstable production process and large fluctuations in product quality.

[0003] In summary, there is at least one of the following technical problems: The particle size screening in the traditional deer antler powder preparation process is not accurate and multi-stage screening is difficult to achieve; Lack of real-time granularity measurement and feedback mechanism leads to uneven granularity.

[0004] Particle size detection is delayed or missing, and product quality consistency cannot be guaranteed. In traditional processes, deer antler powder particle size detection is mostly offline sampling detection, which has a lag and is difficult to monitor particle size fluctuations in real time during the production process. It is easy to cause batch production of unqualified products or mixing them into qualified products, affecting the final quality.

[0005] Unqualified products are difficult to eliminate quickly, leading to quality risks. In traditional preparation, even if antler powder with unqualified particle size is found, it is difficult to separate it in time during the production process, which can easily cause unqualified products to mix with qualified products, increase subsequent sorting costs or directly affect product quality.

[0006] Traditionally, antler powder needs to be manually sorted and packed into barrels after grading, which is not only labor-intensive, but also prone to mixing of antler powders of different particle sizes due to human operational errors, affecting the accuracy and consistency of product grading.

[0007] The screening and measurement processes have poor coordination, and production parameters cannot be dynamically optimized. In traditional processes, screening, measurement, barrel loading and other links are independent of each other and lack linkage control. When the particle size fluctuates, production parameters such as screening force and feed speed cannot be adjusted in time, which can easily lead to reduced production efficiency or material waste.

[0008] The degree of automation is low, it relies on manual operation and has poor stability. In the traditional preparation process, screening, feeding, testing, barreling and other links mostly rely on manual intervention. Not only is the labor intensity high, but the randomness of manual operation can easily lead to an unstable production process and large fluctuations in product quality. Summary of the Invention

[0009] The main purpose of the present invention is to provide a laser measurement-based deer antler powder preparation system and its use method to address the existing problems of inaccurate particle size screening and difficulty in achieving multi-stage screening during the traditional deer antler powder preparation process; the lack of real-time particle size measurement and feedback mechanisms, resulting in uneven particle size; and delayed or missing particle size detection, which cannot ensure product quality consistency. In traditional processes, deer antler powder particle size detection is mostly performed through offline sampling, which has hysteresis and makes it difficult to monitor particle size fluctuations during production in real time. This can easily lead to the mass production of substandard products or their mixing with qualified products, affecting the final quality. Substandard products are difficult to quickly remove, resulting in quality risks. In traditional preparation, even if deer antler powder with substandard particle size is discovered, it is difficult to separate it in time during the production process, which can easily cause substandard products to mix with qualified products, increase subsequent sorting costs, or directly affect product quality. Traditional deer antler powder grading requires manual sorting and barreling, which is not only labor-intensive but also prone to mixing deer antler powder of different particle sizes due to human error, affecting the accuracy and consistency of product grading. The screening and measurement processes have poor synergy, and production parameters cannot be dynamically optimized. In traditional processes, screening, measurement, and barreling are independent of each other and lack linkage control. When particle size fluctuates, production parameters such as screening force and feed speed cannot be adjusted in time, which can easily lead to reduced production efficiency or material waste. The degree of automation is low, relying on manual operation and poor stability. In traditional preparation processes, screening, feeding, testing, barreling and other links often rely on manual intervention. Not only is the labor intensity high, but the randomness of manual operation can easily lead to unstable production processes and large fluctuations in product quality. This is at least one of the technical problems.

[0010] In order to achieve the above-mentioned purpose, according to one aspect of the present invention, a deer antler powder preparation system based on laser measurement is provided, comprising a screening drum, a fan is provided at one end of the screening drum, a multi-stage sieve grate is provided in the screening drum, and a graded discharge port is provided at the lower end of each stage of the sieve grate, a powder loading conical drum is provided at the upper end of the screening drum, a powder sprinkling chamber is provided at the other end of the screening drum, a powder sprinkling device is provided in the powder sprinkling chamber, a laser measuring chamber is provided at the lower end of the powder sprinkling chamber, a laser particle size measuring instrument is provided on the side wall of the laser measuring chamber, a powder absorber is also provided on the side wall of the laser measuring chamber, a conical discharge port is provided at the lower end of the laser measuring chamber, and a classification turntable is provided at the lower end of the conical discharge port, and the classification turntable classifies and loads the materials according to the particle size status monitored in real time by the laser particle size measuring instrument.

[0011] Preferably, the deer antler powder enters the screening cylinder through the powder loading conical cylinder. Under the action of the fan, the deer antler powder passes through the multi-stage sieve grates in sequence along the screening cylinder. The sieve hole diameter of the sieve grates decreases step by step along the wind direction. The lower end of the screening cylinder on the side of the sieve grates close to the fan is provided with a corresponding graded discharge port. The screened deer antler powder enters the conveying pipe through the graded discharge port in sequence and is conveyed to the container through the conveying pipe.

[0012] Preferably, the antler powder sieved by the sieve enters the powder spreader through a conical cylinder. Driven by the first motor, the powder spreader intermittently sprinkles the antler powder into the powder spreading chamber. The sprinkled antler powder falls into the laser measuring chamber under the action of gravity. The laser particle size measuring instrument measures the particle size of the antler powder in the laser measuring chamber in real time and transmits the measurement results to the controller in real time.

[0013] Preferably, the controller includes a central processing unit, a laser particle size measurement control module, a first motor control module, a second motor control module, a powder absorber control module, a control valve control module, a data processing module, a comparison module, a storage module, a calculation module and a classification module, and the laser particle size measurement control module, the first motor control module, the second motor control module, the powder absorber control module, the control valve control module, the data processing module, the comparison module, the storage module, the calculation module and the classification module are respectively connected to the central processing unit.

[0014] Preferably, the fan blows toward the screening cylinder, and the wind passes through the screening cylinder, and the flow rate is accelerated under the action of the conical cylinder closing structure, driving the antler powder into the powder spreader, and under the action of the accelerated wind force, the antler powder is spread through the spreading pipe of the powder spreader. The controller controls the rotation state of the first motor, the operation state of the fan, and the feeding state of the powdering conical cylinder according to the particle size state of the antler powder measured in real time by the laser particle size meter.

[0015] Preferably, the larger particles of antler powder are subjected to three-stage screening through the sieve, wherein the large particles of antler powder are screened by the first-stage screening grate 21 and then enter the first classification discharge port, the medium particles of antler powder are screened by the second-stage screening grate and then enter the second classification discharge port, and the small particles of antler powder are screened by the third-stage screening grate and then enter the third classification discharge port 17, and then transported to the corresponding container or secondary grinding process through the conveying pipe to achieve three-stage screening; after screening, the smaller particles of antler powder enter the powder sprinkling chamber and the laser measurement chamber for real-time particle size measurement.

[0016] Preferably, a laser particle size measuring instrument is controlled by a controller to measure the antler powder raised in the laser measuring chamber, and the real-time measurement data is transmitted to the controller. The controller controls the calculation module through the central processing unit to calculate the measurement data, and the data measured and calculated by the comparison module are compared with the set threshold value. The measured and calculated data are processed by the data processing module. When the particle size of the antler powder is within the threshold range, under the action of gravity, the antler powder that meets the standards is discharged through the conical discharge port, and according to the particle size grade, the controller controls the classification turntable to dynamically adjust the antler powder cylinder of the corresponding grade to the conical discharge port for loading powder.

[0017] Preferably, when the laser particle size measuring instrument measures that the particle size of the antler powder in the laser measuring cavity does not meet the threshold range or the particle size threshold is intermittently uneven, the controller controls the powder absorbers on both sides to open simultaneously or individually to absorb the antler powder with abnormal particle size in the laser measuring cavity, and the antler powder with abnormal particle size is sucked into the container through the powder absorber.

[0018] Preferably, a second motor is provided on the first base, and the second motor drives the turntable to rotate, and the turntable drives a number of deer antler powders to dynamically move to the conical discharge port according to the monitoring status of the deer antler powders.

[0019] According to another aspect of the present invention, a method for preparing deer antler powder based on laser measurement is provided, comprising: Primary screening: The fan blows the powder toward the screening cylinder. The wind passes through the screening cylinder. Driven by the airflow, the deer antler powder moves along the screening cylinder and passes through the sieve grates with sieve hole diameters that decrease step by step along the wind direction. When passing through each level of sieve grates, the deer antler powder of different particle sizes passes through the sieve grates with corresponding sieve hole diameters in turn according to their own particle size, thus achieving three-level screening of large, medium and small particles. Particle size measurement and further screening: After the sieved antler powder is sprinkled into the laser measurement chamber by a powder spreader, the laser particle size measuring instrument uses the principle of laser scattering to measure the particle size of the antler powder. The laser is irradiated on the antler powder particles and scattered. Particles of different particle sizes scatter light at different angles. By detecting the angle and intensity distribution of the scattered light, the particle size distribution of the antler powder is calculated. The measured data is then transmitted to the controller, which controls each functional module to perform data processing, comparison, and calculation. If the particle size meets the standard, the classification turntable is controlled to load the powder; if the particle size does not meet the standard, the powder absorber is controlled to absorb the deer antler powder with abnormal particle size. At the same time, the controller also adjusts the rotation state of the first motor, the operating state of the fan and the feeding state of the powder loading cone in real time according to the measurement results to achieve closed-loop control of the entire system.

[0020] The application of the technical solution of the present invention has the following technical effects: Deer antler powder is fed through a powder-feeding cone into a screening drum. The fan is turned on, and the wind forces the powder along the screening drum through multiple sieves, each with a diameter that decreases with the wind direction, achieving three-stage screening. Large particles of antler powder are screened by the first-stage screening grate and enter the first-stage discharge port. Medium particles are screened by the second-stage screening grate and enter the second-stage discharge port. Small particles are screened by the third-stage screening grate and enter the third-stage discharge port. The powder is then transported through a conveying pipe to the appropriate container or for secondary grinding. The smaller particles of antler powder after screening pass through the cone and enter the duster. A first motor drives the duster to intermittently sprinkle the powder into the dusting chamber, where it falls by gravity into the laser measurement chamber. A laser particle size analyzer measures the particle size of the powder in the laser measurement chamber in real time and transmits the results to the controller. The controller uses the central processing unit to control the calculation module to calculate the measured data. The comparison module compares the measured and calculated data with the set threshold value, and the data processing module processes the measured and calculated data. When the antler powder particle size is within the threshold range, gravity discharges the antler powder that meets the standard through the conical discharge port. The controller controls the classification turntable to dynamically adjust the antler powder cylinder of the corresponding grade to the bottom of the conical discharge port for powder loading. If the laser particle size measuring instrument detects that the antler powder particle size in the laser measurement chamber does not meet the threshold range or the particle size threshold is intermittently uneven, the controller controls the powder aspirators on both sides to activate simultaneously or independently to aspirate the antler powder of abnormal particle size into the container. This achieves precise multi-stage screening of antler powder, effectively separating the antler powder into large, medium, and small particles, meeting the diverse particle size requirements of different products and improving product quality. Through real-time particle size measurement and feedback control, production parameters can be adjusted promptly to ensure that the antler powder produced meets the standard particle size, reducing material waste and improving production efficiency. The system's automation and intelligent control reduce the intensity of manual operations and improve the stability and consistency of the production process.

[0021] This system uses multi-stage sieves (the diameter of the sieve holes decreases step by step along the wind direction) and is driven by a fan. This allows the antler powder to pass through sieves with different sieve holes in sequence, achieving three-level precise screening of large, medium and small particles, solving the problems of low screening accuracy and fuzzy grading in traditional screening.

[0022] The system uses a laser particle size measuring instrument to measure the raised antler powder in real time in the laser measuring chamber, uses the laser scattering principle to quickly obtain particle size data, and transmits it to the controller in real time, realizing online and dynamic monitoring of particle size, and solving the problem of traditional detection lag and inability to detect unqualified products in a timely manner.

[0023] The system is linked to the laser particle size measuring instrument through a powder absorber: when the measured particle size does not meet the threshold or there is intermittent unevenness, the controller immediately triggers the powder absorber to open, and quickly sucks the antler powder with abnormal particle size into a special container, preventing unqualified products from flowing into the next process, solving the problem of unqualified products being difficult to remove in real time.

[0024] The system works in conjunction with the controller through a classification turntable: based on the laser measurement results, the controller controls the precise rotation of the turntable through the classification module, dynamically adjusting the corresponding grade of deer antler powder barrels to the bottom of the discharge port, realizing automatic classification and loading, and solving the problems of low efficiency and large errors in manual classification.

[0025] Through the closed-loop control logic of the controller (the central processing unit coordinates laser measurement, motor, fan, feed and other modules), the system can dynamically adjust parameters such as the first motor (powder sprinkling frequency), fan (wind force), and powder loading cone (feed speed) according to real-time particle size data, thereby achieving coordinated optimization of screening, measurement, and conveying, solving the problem of fixed parameters and inability to dynamically adapt to particle size changes in traditional production.

DETAILED DESCRIPTION

[0028] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] like Figures 1 to 11 As shown, an embodiment of the present invention provides a deer antler powder preparation system based on laser measurement, comprising: a screening drum 13, a fan 15 is provided at one end of the screening drum 13, a multi-stage sieve grate 21 is provided in the screening drum 13, and a graded discharge port 17 is provided at the lower end of each stage of the sieve grate 21; a powder loading conical drum 14 is provided at the upper end of the screening drum 13; a powder sprinkling chamber 11 is provided at the other end of the screening drum 13, a powder sprinkling device 20 is provided in the powder sprinkling chamber 11, a laser measuring chamber 9 is provided at the lower end of the powder sprinkling chamber 11, a laser particle size measuring instrument 8 is provided on the side wall of the laser measuring chamber 9, a powder absorber 7 is also provided on the side wall of the laser measuring chamber 9, a conical discharge port 6 is provided at the lower end of the laser measuring chamber 9, and a classification turntable 3 is provided at the lower end of the conical discharge port 6. The classification turntable 3 classifies and loads the deer antler powder into the deer antler powder drum 4 according to the particle size state monitored in real time by the laser particle size measuring instrument 8.

[0030] In this embodiment, antler powder enters the screening drum 13 through the powder-feeding conical drum 14. Under the action of the fan 15, the antler powder passes through the multi-stage sieve grates 21 along the screening drum 13. The diameter of the sieve grates 21 decreases step by step along the wind direction. The lower end of the screening drum 13, on the side of the sieve grates 21 near the fan 15, is provided with a corresponding graded discharge port 17. The screened antler powder passes through the graded discharge port 17 and enters the conveying pipe through which it is transported to the container. Specifically, the powder-feeding conical drum 14 guides the antler powder into the screening drum 13. The conical structure allows the antler powder to enter the screening drum 13 evenly and stably, ensuring the continuity and stability of the screening process. The fan 15 provides wind power to the screening drum 13, causing the antler powder to move within the screening drum 13 and pass through the multi-stage sieve grates 21 to complete the screening process; at the same time, with the cooperation of the conical drum 12, it accelerates the antler powder to enter the powder spreader 20, and is the power source for the entire system to achieve screening and transportation. The support arm 16 supports and fixes some components of the system, enhancing the structural strength and stability of the system and ensuring that each component can operate normally during the working process. The graded discharge port 17 corresponds to each level of the sieve grate 21, so that the antler powder after screening can smoothly enter the conveying pipe, realizing the separation and transportation of antler powder of different particle sizes, and providing convenience for subsequent classification, storage and processing. The second base 18 and the first base 1 together provide stable support for the system, ensuring the stability of the system during operation and dispersing the pressure and vibration generated by the system during operation. The second motor 19 drives the turntable 3 to rotate, providing power for the rotation of the turntable 3, so that the turntable 3 can rotate and position according to the set program, realizing accurate control of the antler powder drum 4. Driven by the first motor 10, the duster 20 sprinkles the antler powder into the dusting chamber 11, allowing it to evenly enter the laser measurement chamber 9 for particle size measurement, improving measurement accuracy. The sieve 21 sieves the antler powder. With different mesh diameters, the sieve 21 separates antler powder of varying particle sizes. It is the core component for grading antler powder. The mesh design and arrangement determine the accuracy and effectiveness of the sieving process.

[0031] In this embodiment, antler powder sieved by grate 21 passes through conical barrel 12 and enters powder dispenser 20. Driven by first motor 10, powder dispenser 20 intermittently sprinkles antler powder into powder dispensing chamber 11. The scattered antler powder falls into laser measurement chamber 9 under the action of gravity. Laser particle size analyzer 8 measures the particle size of the antler powder in laser measurement chamber 9 in real time and transmits the measurement results to controller 22 in real time. Specifically, conical discharge port 6 guides antler powder that meets the particle size standard smoothly into the corresponding antler powder barrel 4 on turntable 3. The conical structure's diversion effect allows for accurate and rapid discharge of antler powder, minimizing blockage and spillage during discharge. When laser particle size analyzer 8 detects that the particle size of the antler powder in laser measurement chamber 9 does not meet the threshold range or that the particle size threshold is intermittently uneven, powder aspirator 7 activates to aspirate the abnormally sized antler powder into a container, ensuring product quality and preventing unqualified product from flowing into the next process. Its operating principle is to use an internal fan to generate negative pressure, sucking the antler powder within the laser measurement chamber 9 and transporting it to a designated container. The laser particle size analyzer 8 measures the antler powder in the laser measurement chamber 9 in real time. Using the principle of laser scattering, the particle size information of the antler powder is converted into an electrical signal or digital signal and transmitted to the controller 22, providing accurate data for the system's particle size control. The laser measurement chamber 9 provides measurement space for the laser particle size analyzer 8, ensuring that the antler powder is evenly distributed within the chamber, enabling the laser particle size analyzer 8 to accurately measure the particle size of the antler powder. Its closed structural design reduces interference from external factors on the measurement results. A first motor 10 drives the powder dispenser 20 to rotate, intermittently spreading the antler powder into the powder dispensing chamber 11, allowing the antler powder to evenly enter the laser measurement chamber 9 for particle size measurement, thereby improving the accuracy and representativeness of the measurement. The powder dispensing chamber 11 provides a working space for the powder dispenser 20, allowing the antler powder to be fully lifted and evenly distributed within the chamber, creating favorable conditions for subsequent particle size measurement. Conical drum 12 guides and accelerates the sieved antler powder. Driven by the wind from fan 15, its conical structure accelerates the airflow, allowing the powder to flow smoothly into duster 20, improving its delivery efficiency. Sieving drum 13 is equipped with multi-stage grates 21. Driven by fan 15, this sieve drum 13 achieves multi-stage sieving of the antler powder. This is a key component in the entire system's particle size classification, separating antler powder of varying particle sizes through the sieving action of grates 21.

[0032] In this embodiment, the controller 22 includes a central processing unit 23, a laser particle size measurement control module 24, a first motor control module 25, a second motor control module 26, a powder absorber control module 27, a control valve control module 28, a data processing module 29, a comparison module 30, a storage module 31, a calculation module 32, and a classification module 33. The laser particle size measurement control module 24, the first motor control module 25, the second motor control module 26, the powder absorber control module 27, the control valve control module 28, the data processing module 29, the comparison module 30, the storage module 31, the calculation module 32, and the classification module 33 are respectively connected to the central processing unit 23. Specifically, through the coordinated operation of each functional module, unified control and management of each component of the system is achieved. According to the measurement results of the laser particle size analyzer 8, the system operating parameters are adjusted in real time to ensure product quality and production efficiency. The central processing unit 23 serves as the core computing component of the controller 22, coordinating and controlling the operation of each functional module, processing and analyzing data from components such as the laser particle size analyzer 8, and issuing control instructions according to preset programs and algorithms to achieve intelligent control of the entire system. The laser particle size measurement control module 24 controls the operation of the laser particle size analyzer 8, including setting measurement parameters and starting and stopping the measurement process, ensuring that the laser particle size analyzer 8 can accurately and stably perform particle size measurements and promptly transmit the measurement data to the central processing unit 23. The first motor control module 25 controls the rotation state of the first motor 10. According to the instructions of the central processing unit 23, it adjusts the speed and rotation time of the first motor 10 to achieve control over the frequency and intensity of the deer antler powder spread by the duster 20. The second motor control module 26 controls the rotation state of the second motor 19. According to the instructions of the central processing unit 23, it adjusts the speed and rotation angle of the second motor 19 to achieve precise control of the turntable 3 and ensure that the deer antler powder drum 4 can accurately move to the unloading position. The powder suction device control module 27 controls the opening and closing of the powder suction device 7. When the laser particle size analyzer 8 measures deer antler powder of abnormal particle size, the powder suction device 7 is promptly opened according to the instructions of the central processing unit 23 to suck away the unqualified deer antler powder.

[0033] In this embodiment, each discharge position is provided with a control valve. The control valve control module 28 controls the opening and closing of the valve, regulating the flow and direction of the material and airflow in the system, and ensuring the stability and accuracy of the system operation. The data processing module 29 processes the data transmitted by the laser particle size analyzer 8, including data filtering, noise reduction, format conversion, etc., to improve the quality and usability of the data and provide an accurate data basis for subsequent calculations and analysis. The comparison module 30 compares the data processed by the data processing module 29 with a set threshold value to determine whether the particle size of the deer antler powder meets the standard, and transmits the comparison result to the central processing unit 23 to provide a basis for the control decision of the system. The storage module 31 stores various data during the operation of the system, including the measurement data of the laser particle size analyzer 8, system operating parameters, set threshold values, etc., to facilitate data query and analysis, and provide data support for the optimization and improvement of the system. The calculation module 32 calculates according to the set algorithm based on the measurement data of the laser particle size analyzer 8 to obtain relevant parameters such as the particle size distribution of the deer antler powder, providing data support for the control and quality assessment of the system. The classification module 33 controls the classification turntable 3 to move the antler powder tubes 4 of corresponding grades to the bottom of the conical discharge port 6 according to the comparison result of the comparison module 30 and the calculation result of the calculation module 32, so as to realize the accurate classification and loading of antler powder of different particle size grades.

[0034] In this embodiment, the fan 15 blows toward the screening drum 13. The wind passes through the screening drum 13 and the flow rate is accelerated under the action of the closing structure of the conical drum 12, driving the antler powder into the powder spreader 20. Under the action of the accelerated wind, the antler powder is spread through the powder spreading pipe of the powder spreader 20. The controller 22 controls the rotation state of the first motor 10, the operation state of the fan 15, and the feeding state of the powdering conical drum 14 according to the particle size state of the antler powder measured in real time by the laser particle size measuring instrument 8.

[0035] In this embodiment, larger particles of antler powder are subjected to three-stage screening through the sieve 21, wherein the large particles of antler powder enter the first classification discharge port 17 after being screened by the first-stage sieve, the medium particles of antler powder enter the second classification discharge port 17 after being screened by the second-stage sieve, and the small particles of antler powder enter the third classification discharge port 17 after being screened by the third-stage sieve 21, and then are transported to the corresponding container or secondary grinding process through the conveying pipe to realize three-stage screening; after screening, the smaller particles of antler powder enter the powder sprinkling chamber 11 and the laser measurement chamber 9 for real-time particle size measurement.

[0036] In this embodiment, the laser particle size measuring instrument 8 is controlled by the controller 22 to measure the antler powder raised in the laser measuring chamber 9, and the real-time measurement data is transmitted to the controller 22. The controller 22 controls the calculation module 32 to calculate the measurement data through the central processing unit 23, and compares the measured and calculated data with the set threshold value through the comparison module 30. The measured and calculated data are processed by the data processing module 29. When the particle size of the antler powder is within the threshold range, under the action of gravity, the antler powder that meets the standard is discharged through the conical discharge port 6, and according to the particle size grade, the controller 22 controls the classification turntable 3 to dynamically adjust the antler powder tube 4 of the corresponding grade to the conical discharge port 6 for loading powder.

[0037] In this embodiment, when the laser particle size measuring instrument 8 measures that the particle size of the antler powder in the laser measuring cavity 9 does not meet the threshold range or the particle size threshold is intermittently uneven, the controller 22 controls the powder absorbers 7 on both sides to open simultaneously or individually to absorb the antler powder with abnormal particle size in the laser measuring cavity 9, and the antler powder with abnormal particle size is sucked into the container through the powder absorber 7.

[0038] In this embodiment, a second motor 19 is provided on the first base 1, and the second motor 19 drives the turntable 3 to rotate, and the turntable 3 drives a number of deer antler powder cylinders 4 to dynamically move to the conical discharge port 6 according to the monitoring status of the deer antler powder. Specifically, the first base 1 serves as the basic support component of the entire system, and is used to install the second electricity Components such as the motor 19 and turntable 3 provide stable support for the system, ensuring stability during operation. This robust structural design disperses pressure and vibration generated during system operation, preventing system instability from impacting production accuracy and equipment life. A support frame 2 is mounted on the first base 1. The support frame 2 assists in supporting parts of the system, enhancing overall stability and reliability. Working in conjunction with the first base 1, it ensures that all components maintain their correct positioning during operation, preventing equipment failures and production errors caused by structural instability. Driven by a second motor 19, the turntable 3 dynamically moves several antler powder cartridges 4 to the bottom of the conical discharge port 6 based on the monitored antler powder status. This allows for the classified loading of antler powder of varying particle size grades, improving loading accuracy and efficiency. The motor drives the turntable 3's shaft, rotating and positioning it according to a pre-programmed sequence, accurately moving the corresponding antler powder cartridge 4 to the discharge position. The antler powder cartridges 4 are used to store the classified and loaded antler powder, providing convenient storage conditions for subsequent use and transportation, and protecting the powder from contamination and damage during storage. The fixing plate 5 fixes and supports the relevant components in the system, ensuring that the relative positions of the components remain unchanged during operation, improving the overall rigidity and stability of the system, and ensuring the reliability of the system operation.

[0039] Working principle: The air blows toward the screening drum 13 through the fan 15. The wind passes through the screening drum 13, and driven by the airflow, the deer antler powder moves along the screening drum 13. Since the sieve hole diameter of the sieve grate 21 decreases step by step along the wind direction, the deer antler powder of different particle sizes, when passing through each level of the sieve grate 21, passes through the sieve grate 21 with the corresponding sieve hole diameter in sequence according to its own particle size, thereby achieving three-level screening of large, medium, and small particles. After the sieved deer antler powder is sprinkled into the laser measurement chamber 9 by the duster 20, the laser particle size measuring instrument 8 uses the principle of laser scattering to measure the particle size of the deer antler powder. The laser is irradiated on the deer antler powder particles and scattered. The scattered light angles of particles of different particle sizes are different. By detecting the angle and intensity distribution of the scattered light, the particle size distribution of the deer antler powder can be calculated. After the measurement data is transmitted to the controller 22, the central processing unit 23 in the controller 22 controls each functional module to perform data processing, comparison, and calculation according to the preset program. If the particle size meets the standard, the classification turntable 3 is controlled to load the powder. If the particle size does not meet the standard, the powder suction device 7 is controlled to remove the deer antler powder of abnormal particle size. Simultaneously, based on the measurement results, the controller 22 adjusts the rotation state of the first motor 10, the operating state of the fan 15, and the feeding state of the powder loading cone 14 in real time, achieving closed-loop control of the entire system.

[0040] Another embodiment of the present invention provides a method for preparing deer antler powder based on laser measurement, comprising: Primary screening: The fan 15 blows the powder toward the screening drum 13. The wind passes through the screening drum 13. Driven by the airflow, the deer antler powder moves along the screening drum 13 and passes through the sieve grates 21 with sieve hole diameters that gradually decrease along the wind direction. When passing through the sieve grates 21 at each level, the deer antler powder of different particle sizes passes through the sieve grates 21 with corresponding sieve hole diameters according to their own particle size, thus achieving three-level screening of large, medium and small particles. Particle size measurement and further screening: After the sieved antler powder is sprinkled into the laser measurement chamber 9 by the powder spreader 20, the laser particle size measuring instrument 8 uses the principle of laser scattering to measure the particle size of the antler powder. The laser is irradiated on the antler powder particles and scattered. Particles of different particle sizes scatter light at different angles. By detecting the angle and intensity distribution of the scattered light, the particle size distribution of the antler powder is calculated. The measured data is then transmitted to the controller 22, which controls each functional module to perform data processing, comparison, and calculation; If the particle size meets the standard, the classification turntable 3 is controlled to load powder; if the particle size does not meet the standard, the powder absorber 7 is controlled to absorb the deer antler powder with abnormal particle size. At the same time, the controller 22 also adjusts the rotation state of the first motor 10, the operating state of the fan 15 and the feeding state of the powder loading cone 14 in real time according to the measurement results to achieve closed-loop control of the entire system.

[0041] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects: Antler powder is fed into the screening drum 13 through the powder-feeding conical drum 14. The fan 15 is turned on. Under the influence of the wind, the antler powder passes through the multi-stage sieve grates 21 along the screening drum 13. The mesh diameter of the sieve grates 21 decreases step by step along the wind direction, achieving three-stage screening. Large-particle antler powder is screened by the first-stage screening grate 21 and enters the first-stage discharge port 17. Medium-particle antler powder is screened by the second-stage screening grate and enters the second-stage discharge port 17. Small-particle antler powder is screened by the third-stage screening grate 21 and enters the third-stage discharge port 17. The powder is then transported to the corresponding container or subjected to secondary grinding via a conveying pipe. The smaller-particle antler powder after screening passes through the conical drum 12 and enters the duster 20. The first motor 10 drives the duster 20 to intermittently sprinkle the antler powder into the dusting chamber 11. The dusted antler powder falls into the laser measurement chamber 9 under the action of gravity. The laser particle size measuring instrument 8 measures the particle size of the antler powder in the laser measuring chamber 9 in real time and transmits the measurement results to the controller 22 in real time. The controller 22 controls the calculation module 32 through the central processing unit 23 to calculate the measurement data, compares the measured and calculated data with the set threshold value through the comparison module 30, and processes the measured and calculated data through the data processing module 29. When the particle size of the antler powder is within the threshold range, under the action of gravity, the antler powder that meets the standard is discharged through the conical discharge port 6, and the controller 22 controls the classification turntable 3 to dynamically adjust the antler powder barrel 4 of the corresponding grade to the conical discharge port 6 for powder loading. When the laser particle size measuring instrument 8 measures that the particle size of the antler powder in the laser measuring chamber 9 does not meet the threshold range or the particle size threshold is intermittently uneven, the controller 22 controls the powder suction devices 7 on both sides to open simultaneously or individually to suck the antler powder of abnormal particle size into the container. This system achieves precise multi-stage screening of deer antler powder, effectively separating it into large, medium, and small particles. This meets the diverse particle size requirements of different products and improves product quality. Real-time particle size measurement and feedback control enable timely adjustment of production parameters to ensure that the produced deer antler powder particle size meets standards, reducing material waste and improving production efficiency. The system's automated and intelligent control reduces manual labor and improves the stability and consistency of the production process.

[0042] This system uses multi-stage sieves 21 (the diameter of the sieve holes decreases step by step along the wind direction) and the wind power of the fan 15 to make the deer antler powder pass through the sieves 21 with different sieve holes in sequence, achieving three-level precise screening of large, medium and small particles, solving the problems of low screening accuracy and fuzzy classification in traditional screening.

[0043] The system uses a laser particle size measuring instrument 8 to measure the raised deer antler powder in real time in the laser measuring chamber 9, uses the laser scattering principle to quickly obtain particle size data, and transmits it to the controller 22 in real time, realizing online and dynamic monitoring of particle size, and solving the problem of traditional detection lag and inability to detect unqualified products in time.

[0044] The system is linked to the laser particle size measuring instrument 8 through the powder absorber 7: when the measured particle size does not meet the threshold or there is intermittent unevenness, the controller 22 immediately triggers the powder absorber 7 to open, and quickly sucks the deer antler powder with abnormal particle size into a special container, preventing unqualified products from flowing into the next process, solving the problem of unqualified products being difficult to remove in real time.

[0045] The system works in coordination with the controller 22 through the classification turntable 3: the controller 22 controls the precise rotation of the turntable 3 through the classification module 33 based on the laser measurement results, and dynamically adjusts the deer antler powder tubes 4 of the corresponding grade to the bottom of the discharge port, realizing automatic classification and loading, and solving the problems of low efficiency and large errors in manual classification.

[0046] Through the closed-loop control logic of the controller 22 (the central processing unit 23 coordinates the laser measurement, motor, fan 15, feeding and other modules), the system can dynamically adjust the parameters such as the first motor 10 (powder sprinkling frequency), fan 15 (wind force), and powder loading cone 14 (feeding speed) according to real-time particle size data, thereby achieving coordinated optimization of screening, measurement, and conveying, and solving the problem of fixed parameters and inability to dynamically adapt to particle size changes in traditional production.

[0047] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
