Description

Technical Field

[0001] This invention relates to the field of millet processing and sorting technology, specifically a sorting device for a millet processing production line. Background Technology

[0002] In the millet processing and production process, sorting is a crucial step in ensuring the quality of millet. Its main function is to remove light impurities (such as dust, broken rice husks, and shriveled grains) and to achieve preliminary grading of millet grains. Therefore, millet processing production lines are generally equipped with sorting equipment. Currently, most millet processing production line sorting equipment on the market is based on screen vibration sorting, and some equipment is supplemented by a simple air separation structure. By feeding millet into the inlet, the screen vibration disperses the millet and initially filters out large particles of impurities. Then, combined with airflow, light impurities in the millet are blown away, thus completing the basic sorting operation and laying the foundation for subsequent millet refining (such as milling and polishing).

[0003] Existing millet processing line sorting equipment has several shortcomings in practical applications, failing to meet the demands for efficient and precise sorting: First, the sorting level is limited, and millet tends to accumulate in sorting areas (such as the guide structure and the surface of the sorting plate), resulting in insufficient contact between the millet and the sorting airflow, leading to incomplete sorting and a high residue of light impurities. Second, the air separation parameters are fixed, making it impossible to flexibly adjust the airflow type according to the different states of the millet to be sorted (such as different humidity levels and impurity contents). This makes it unsuitable for addressing issues such as high-humidity millet easily agglomerating and clogging the sorting channel, and low-humidity millet easily breaking due to improper airflow. Third, the feed inlet size is fixed, making it difficult to adjust the feed dispersion according to the millet flow rate, resulting in uneven distribution of millet on the guide structure, with some areas having excessively dense millet that cannot be fully sorted. Therefore, there is an urgent need to develop a millet processing line sorting device to overcome these shortcomings in current practical applications. Summary of the Invention

[0004] The purpose of this invention is to provide a sorting device for a millet processing production line to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A sorting device for a millet processing production line includes a millet selection bracket, which comprises a feeding section and an inner frame, and further includes:

[0007] V-shaped material guiding and sorting column, the V-shaped material guiding and sorting column is fixedly installed in the inner frame and is set close to the unloading part, and the V-shaped material guiding and sorting column is also equipped with an air separation device for sorting millet;

[0010] When the two sorting ramps retract into the interior of the inner frame, the two sorting ramps are completely located directly below the V-shaped guide sorting column; when the two inner frames expand to the outside of the inner frame, the two sorting ramps are respectively located below the inclined surface of the V-shaped guide sorting column, for secondary air separation of millet falling on the inclined surface of the V-shaped guide sorting column.

[0011] As a further aspect of the present invention: the air separation device includes:

[0014] As a further aspect of the present invention: the angle between the sorting inclined plate and the horizontal plane is smaller than the angle between the inclined surface of the V-shaped guide sorting column and the horizontal plane;

[0015] When the two sorting ramps move in opposite directions to their maximum distance apart, the millet falling through the inclined surface of the V-shaped guide sorting column lands exactly at the top of the sorting ramp.

[0025] Among them, multiple sliding partition plates are arranged close to the feeding section;

[0026] The flow state adjustment slider is provided in multiple ways. All multiple flow state adjustment sliders are inserted into the Xiaomi Selected bracket and slidably connected to the Xiaomi Selected bracket. The flow state adjustment slider is also slidably connected to the sliding partition plate.

[0027] And a telescopic drive assembly, which is connected to the Xiaomi Select bracket and the flow state adjustment slider respectively, and is used to drive the flow state adjustment slider to move on the Xiaomi Select bracket to change the size of the bottom discharge port of the sliding partition plate.

[0028] As a further aspect of the present invention: the end of the flow state adjusting slider near the sliding partition plate is provided with an inclined surface, and a discharge space is formed between the inclined surface, the sliding partition plate and the V-shaped material guiding and sorting column;

[0029] A discharge port is formed between the bottom end of the inclined surface and the V-shaped material guiding and sorting column;

[0030] Driven by the telescopic drive component, the distance between the bottom of the inclined surface and the inclined surface of the V-shaped guide sorting column will change. By changing the size of the discharge port, the dispersion of millet scattered on the inclined surface of the V-shaped guide sorting column through the feeding part can be changed.

[0031] As a further aspect of the present invention: the telescopic drive component includes:

[0032] The U-shaped bracket is fixedly installed on the Xiaomi Select bracket;

[0040] An execution control module is used to execute control commands to drive the actions of the sorting and air-separating equipment;

[0041] It also includes a human-machine interface module for displaying operating data, setting operating parameters, and issuing fault alarms.

[0042] Compared with the prior art, the beneficial effects of the present invention are:

[0043] 1. Solve the problem of millet accumulation and improve sorting uniformity: Through the V-shaped structure design of the V-shaped material guide sorting column, the millet can be guided to slide evenly along the inclined surfaces on both sides under its own gravity, avoiding the accumulation of millet in the sorting area. At the same time, the sliding partition plate performs preliminary sorting of millet, ensuring that the millet is in full contact with the sorting airflow, laying the foundation for subsequent accurate sorting.

[0044] 2. Flexible adaptation of air separation parameters to meet the needs of different millet conditions: The air separation equipment is connected to an external air source through the air separation inlet connector. It can control the output of hot or cold air according to the actual situation of the millet to be separated (such as high humidity millet needs hot air to reduce moisture content and prevent blockage, and low humidity millet needs cool air to prevent breakage). It can adapt to the separation of millet with different humidity and different impurity conditions, and avoid separation problems (caking, breakage, etc.) caused by fixed air separation parameters.

[0045] 3. Achieve flexible switching of sorting levels and improve sorting accuracy: With the movable design of the two sorting inclined plates in the fine sorting equipment, the sorting mode can be flexibly switched according to sorting needs; when only preliminary sorting is needed, the two sorting inclined plates are controlled to retract into the inner frame to assist in air separation of millet scattered in the air; when secondary fine sorting is needed, the two sorting inclined plates are driven to extend below the inclined surface of the V-shaped guide sorting column, and secondary air separation is carried out in conjunction with the second sorting hole on the sorting inclined plate, which effectively removes the fine impurities remaining after the preliminary sorting and significantly improves the sorting accuracy;

[0046] 4. Precisely control the dispersion state of the feed to adapt to different millet flow rates: The flow state adjustment slider is moved by the telescopic drive component, which can change the size of the discharge port between the sliding partition plate and the V-shaped guide sorting column. When the millet flow rate is large, the discharge port is enlarged to avoid blockage. When the flow rate is small, the discharge port is enlarged to ensure that the millet is evenly distributed on the inclined surface of the V-shaped guide sorting column. At the same time, the discharge port can be adjusted to make the millet slide down from the top of the V-shaped guide sorting column, ensuring that the millet is fully in contact with the airflow and improving the sorting and dehumidification effect.

[0047] 5. Improve the adjustment accuracy of sorting components and enhance the versatility of the equipment: The synchronous drive unit, through the sliding cooperation of slide one, slide two and the supporting slide plate, combined with the drive of the interval adjustment telescopic cylinder, can accurately control the two sorting inclined plates to move simultaneously in opposite directions or towards each other, ensuring that the adjustment accuracy of the spacing between the sorting inclined plates reaches ±1mm. It can accurately control the contact time and position between millet and sorting inclined plates according to the millet sorting requirements of different output and different impurity content, significantly improving the versatility of the equipment and the sorting reliability.

[0048] 6. Achieve closed-loop intelligent control to ensure sorting stability and traceability: The detection and control system adopts a closed-loop architecture of "monitoring-processing-control-interaction". It collects millet status data in real time through humidity sensors and light impurity content sensors. After being processed and analyzed by an industrial-grade microcontroller, control commands are generated to precisely control the actions of the air separator and the fine separator. At the same time, it can store 24 hours of operating data and equipment action logs for easy traceability and parameter optimization. In addition, the human-machine interaction module can display real-time data, support manual parameter setting, and the alarm buzzer can promptly remind you when parameters are abnormal or equipment malfunctions, further ensuring the stable operation of the sorting operation.

Detailed Implementation

[0060] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0061] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0062] Please see Figures 1-10 The present invention provides a sorting device for a millet processing production line, including a millet selection bracket 1, which consists of a feeding part 3 and an inner frame 12, and further includes:

[0063] V-shaped material guiding and sorting column 9, the V-shaped material guiding and sorting column 9 is fixedly installed in the placement inner frame 12 and is set close to the unloading part 3, and the V-shaped material guiding and sorting column 9 is also equipped with an air separation device for sorting millet;

[0064] The inner frame 12 is further provided with at least one set of selected devices;

[0065] The sorting device includes two symmetrically arranged sorting ramps 13. The two sorting ramps 13 can move simultaneously in opposite directions or towards each other within the placement inner frame 12, and the sorting ramps 13 are also connected to the air sorting device.

[0066] When the two sorting ramps 13 retract into the interior of the inner frame 12, the two sorting ramps 13 are completely located directly below the V-shaped guide sorting column 9; when the two inner frames 12 extend to the outside of the inner frame 12, the two sorting ramps 13 are respectively located below the inclined surface of the V-shaped guide sorting column 9, for secondary air separation of millet falling on the inclined surface of the V-shaped guide sorting column 9.

[0067] In the millet processing and sorting operation, the millet, after being sorted by screen vibration, is first fed into the feeding section 3 of the millet selection bracket 1, entering the sorting space composed of the feeding section 3 and the inner frame 12. Existing millet processing production line sorting equipment generally suffers from the problem of a single sorting level and millet easily accumulating in the sorting area, resulting in incomplete sorting. In this invention, the V-shaped guide sorting column 9 is fixed inside the inner frame 12 and close to the feeding section 3. Its V-shaped structure can guide the millet to slide evenly down the inclined surfaces on both sides under its own gravity, avoiding accumulation. At the same time, during the millet sliding process, the air separation device on the V-shaped guide sorting column 9 can perform preliminary air separation and impurity removal on the sliding millet. The selection device inside the inner frame 12 works in coordination according to the sorting requirements (for example, working in coordination according to the moisture content and light impurity content of the millet): when only preliminary sorting is required, the two sorting inclined plates 13 are controlled to retract synchronously into the inner frame 12, and Located directly below the V-shaped guide sorting column 9, the millet falling from the inclined surface of the V-shaped guide sorting column 9 will not come into contact with the sorting inclined plate 13. The sorting inclined plate 13 can then perform a blowing operation to air-separate the millet scattered in the air, or it can be left un-blown, saving energy while ensuring the quality of millet sorting. When secondary fine sorting is required to remove residual light impurities or rice husks and other impurities adhering to the millet, the two sorting inclined plates 13 are driven to move towards each other simultaneously and extend to the outside of the inner frame 12, so that the two sorting inclined plates 13 are respectively below the two inclined surfaces of the V-shaped guide sorting column 9. As the millet falls from the inclined surface, the air separation equipment continues to work, and the sorting inclined plates 13 receive and cooperate to complete the secondary screening (impact and secondary air separation). This effectively solves the problems of low sorting accuracy and many residual impurities in traditional equipment, realizes flexible switching of sorting levels, and improves the accuracy and efficiency of millet sorting.

[0068] In one embodiment of the present invention, please refer to Figures 1-10 The air separation device includes:

[0069] Air separation hole 11, the number of which is multiple, and the multiple air separation holes 11 are evenly opened on the inclined surface of the V-shaped guide material sorting column 9;

[0070] The multiple air separation holes 11 on the V-shaped material guiding and sorting column 9 are connected to an external air source through the air separation air inlet connector 2. The external air source is used to deliver hot or cool air to the air separation holes 11.

[0071] The angle between the sorting inclined plate 13 and the horizontal plane is smaller than the angle between the inclined surface of the V-shaped guide sorting column 9 and the horizontal plane;

[0072] When the two sorting ramps 13 move in opposite directions to the maximum distance between them, the millet falling through the inclined surface of the V-shaped guide sorting column 9 lands at the top of the sorting ramp 13.

[0073] By combining the air-separation equipment with the sorting ramp, the problems of fixed air-separation parameters, inability to adapt to millet in different states (such as different humidity, impurity content, and impurity state), and unreasonable sorting paths in existing millet sorting equipment are effectively solved. In operation, the external air source is connected to the internal air passage of the V-shaped guide sorting column 9 through the air-separation inlet connector 2. Operators can control the output of hot or cold air from the external air source according to the actual condition of the millet to be sorted (e.g., high-humidity millet is prone to clumping, requiring hot air to reduce moisture content and prevent blockage of the sorting channel; low-humidity millet is brittle, requiring cool air to prevent particle breakage). The airflow is stably blown out through multiple evenly spaced air-separation holes 11 on the inclined surface of the V-shaped guide sorting column 9, forming a uniform air-separation airflow field. Under the action of the airflow, light impurities (such as dust, broken millet shells, and shriveled particles) are carried away by the airflow, while qualified millet continues to fall along the inclined surface due to its own gravity. Simultaneously... The angle between the sorting inclined plate 13 and the horizontal plane is smaller than the angle between the inclined surface of the V-shaped guide sorting column 9 and the horizontal plane. This angle design ensures that millet falls accurately onto the upper surface of the sorting inclined plate 13 when it falls from the inclined surface, and slows down the sliding speed of millet on the sorting inclined plate 13. This ensures that the millet has sufficient time to stay on the sorting inclined plate 13 to complete the subsequent screening. When the two sorting inclined plates 13 move in opposite directions to the maximum distance between them, the millet falling from the inclined surface of the V-shaped guide sorting column 9 falls exactly at the top of the sorting inclined plate 13, avoiding the millet from leaking out from the edge of the sorting inclined plate 13 due to the deviation of the landing point. This ensures the continuity and integrity of the sorting process and significantly improves the adaptability and sorting effect of the air classifier.

[0074] In one embodiment of the present invention, please refer to Figures 1-10 The selected equipment also includes:

[0075] Sorting hole 2 18, there are multiple sorting holes 2 18, and the multiple sorting holes 2 18 are evenly distributed on the two sorting inclined plates 13;

[0076] Air supply hose 20, one end of which is connected to the sorting inclined plate 13, and the other end of which is connected to the V-shaped material guide sorting column 9. The air supply hose 20 is also equipped with a solenoid valve to control the on / off of air supply from the air separation equipment to the sorting hole 18.

[0077] And a synchronous drive unit, which is connected to the Xiaomi Selected bracket 1 and the sorting inclined plate 13 respectively, and is used to drive the two sorting inclined plates 13 to move simultaneously in opposite directions or towards each other.

[0078] The synchronous drive unit includes:

[0079] Slide 16 and slide 2 19 are respectively fixedly installed on the Xiaomi Selected Support 1 and the V-shaped guide sorting column 9, and two supporting slide plates 17 are slidably installed between slide 16 and slide 2 19.

[0080] Among them, the two supporting slide plates 17 are fixedly connected to the two sorting inclined plates 13 through bending supports 22 respectively;

[0081] And two interval adjustment telescopic cylinders 21, the two ends of which are fixedly connected to the two sorting inclined plates 13 respectively.

[0082] Through the coordinated design of the aforementioned selected equipment and synchronous drive unit, the problems of existing millet sorting equipment lacking a dedicated air path for secondary sorting and having low synchronous adjustment accuracy have been solved, achieving refined secondary sorting of millet and precise control of the sorting range. During operation, one end of the air supply hose 20 is connected to the internal air passage of the V-shaped guide sorting column 9, and the other end is connected to the internal cavity of the sorting inclined plate 13. The solenoid valve on the air supply hose 20 can control the airflow according to the secondary sorting requirements. When secondary air sorting is required, the solenoid valve is opened, and the airflow in the V-shaped guide sorting column 9 enters the interior of the sorting inclined plate 13 through the air supply hose 20, and then is blown out through multiple evenly distributed sorting holes 18 on the sorting inclined plate 13, separating the millet being sorted or the suspended millet (two...). The millet undergoes secondary air separation (in the first state) to further remove fine impurities (such as tiny shell fragments and fine dust) remaining after the initial air separation, thereby improving the purity of the millet. The synchronous drive unit is responsible for precisely adjusting the position of the two sorting ramps 13: slide block one 16 is fixedly installed on the millet selection bracket 1, slide block two 19 is fixedly installed on the V-shaped guide sorting column 9, and two support slide plates 17 are slidably embedded between slide block one 16 and slide block two 19, and each support slide plate 17 is connected to a sorting ramp through a bending support 22. Plate 13 is fixedly connected, and the two ends of the two interval adjustment telescopic cylinders 21 are respectively connected to the two sorting inclined plates 13. When it is necessary to adjust the spacing of the sorting inclined plates 13, the interval adjustment telescopic cylinders 21 are controlled to extend and retract, which can drive the support slide plate 17 to slide stably along slide seat 16 and slide seat 29, thereby driving the two sorting inclined plates 13 to move simultaneously in opposite directions or towards each other, ensuring the accuracy and stability of the spacing adjustment (different spacing can be adjusted according to different sorting requirements, thereby controlling the contact time and contact position of millet in different states with the sorting inclined plates 13. For example, when the sorting inclined plates 13 extend a short distance, at this time, the millet scattered from the inclined surface contacts part of the sorting inclined plates 13. The contact time is short, and since the bottom of the sorting inclined plates 13 is farthest from the bottom of the inclined surface, the impact of the millet is also greater, thus it can sort impurities or rice husks adhering to the millet). It can adapt to the millet sorting requirements of different yields and different impurity contents, improving the versatility and sorting reliability of the equipment.

[0083] In one embodiment of the present invention, please refer to Figures 1-10 It also includes: a sliding partition plate 7, wherein there are multiple sliding partition plates 7, and the multiple sliding partition plates 7 are respectively fixedly connected to the Xiaomi Selected bracket 1 and the V-shaped guide sorting column 9;

[0084] Among them, multiple sliding partition plates 7 are arranged close to the feeding part 3;

[0085] The flow state adjustment slider 8 is provided in multiple ways. All multiple flow state adjustment sliders 8 are inserted into the Xiaomi Selected bracket 1 and are slidably connected to the Xiaomi Selected bracket 1. The flow state adjustment slider 8 is also slidably connected to the sliding partition plate 7.

[0086] And a telescopic drive assembly, which is connected to the Xiaomi Selected bracket 1 and the flow state adjustment slider 8 respectively, and is used to drive the flow state adjustment slider 8 to move on the Xiaomi Selected bracket 1 to change the size of the bottom discharge port of the sliding partition plate 7.

[0087] The flow state adjusting slider 8 is provided with an inclined surface 15 at one end near the sliding partition plate 7, and a discharge space 10 is formed between the inclined surface 15, the sliding partition plate 7 and the V-shaped guide sorting column 9;

[0088] A discharge port 14 is formed between the bottom end of the inclined surface 15 and the V-shaped material sorting column 9;

[0089] Driven by the telescopic drive component, the distance between the bottom of the inclined surface 15 and the inclined surface of the V-shaped guide sorting column 9 will change. By changing the size of the discharge port 14, the discrete state of the millet scattered on the inclined surface of the V-shaped guide sorting column 9 through the feeding part 3 can be changed.

[0090] The telescopic drive component includes:

[0091] U-shaped bracket 4, which is fixedly installed on the Xiaomi Selected bracket 1;

[0092] Push-pull support plate 6, which is fixedly connected to a plurality of flow state adjusting sliders 8, and the push-pull support plate 6 is also sleeved on the U-shaped bracket 4 and slidably connected to the U-shaped bracket 4;

[0093] And an adjusting telescopic cylinder 5, the two ends of which are fixedly connected to the U-shaped bracket 4 and the push-pull support plate 6 respectively.

[0094] Through the combined design of the sliding partition plate 7, the flow state adjustment slider 8, and the telescopic drive assembly, the problems of fixed discharge port size and uneven distribution of millet on the V-shaped guide column leading to low sorting efficiency in existing millet sorting equipment are solved, achieving precise control of the discrete state of millet discharge. During operation, multiple sliding partition plates 7 are fixed near the discharge section 3 to the millet selection bracket 1 and the V-shaped guide column 9, initially separating the millet falling from the discharge section 3 to prevent concentrated accumulation of millet in a localized area of ​​the V-shaped guide column 9. The telescopic drive assembly drives the flow state adjustment slider 8 to move and adjust the discharge port size. The U-shaped bracket 4 is fixed to the millet selection bracket 1, and the push-pull support plate 6 is fixedly connected to multiple flow state adjustment sliders 8 and slidably fitted onto the U-shaped bracket 4. The two ends of the telescopic cylinder 5 are connected to the U-shaped bracket 4 and the push-pull support plate 6 respectively. Controlling the telescopic cylinder 5 to extend or retract drives the push-pull support plate 6 to slide along the U-shaped bracket 4, thereby synchronously driving multiple flow state adjustment sliders 8 to slide along the millet selection bracket 1 and the sliding partition plate 7. An inclined surface 15 is provided at one end of the flow state adjustment slider 8 near the sliding partition plate 7. The inclined surface 15, the sliding partition plate 7, and the V-shaped guide sorting column 9 form a discharge space 10. The bottom end of the inclined surface 15 and the V-shaped guide sorting column 9 form a discharge port 14. As the flow state adjustment slider 8 slides, the size of the discharge port 14 changes: when the millet flow rate is large, the discharge port 14 is enlarged to prevent millet from clogging in the discharge space 10; when the millet flow rate is small, the discharge port 14 is reduced to ensure that the millet is evenly scattered on the inclined surface of the V-shaped guide sorting column 9, so that each millet can fully contact the air classifier airflow, avoiding sorting omissions caused by uneven distribution, significantly improving the uniformity and efficiency of subsequent air classification and sorting, and adapting to the millet processing needs of different outputs;

[0095] In addition, when the discharge port 14 is at its largest size, some millet entering the V-shaped guide sorting column 9 through the feeding section 3 does not slide down from the top of the V-shaped guide sorting column 9 (it may fall directly to the middle or even the bottom of the inclined surface of the V-shaped guide sorting column 9), which is not conducive to the sorting or dehumidification of millet. At this time, the telescopic drive component is activated to reduce the size of the discharge port 14 (the bottom end of the inclined surface 15 moves closer to the inclined surface of the V-shaped guide sorting column 9), thereby ensuring that the millet falling onto the V-shaped guide sorting column 9 through the feeding section 3 slides down from the top of the V-shaped guide sorting column 9, thus ensuring that the millet is fully in contact with the hot or cool air, which is beneficial to improving the sorting and dehumidification effects.

[0096] In one embodiment of the present invention, a detection and control system is further included, which is signal-connected to the fine sorting device and the air sorting device respectively;

[0097] The detection and control system can control the movement of the sorting ramp of the fine selection device and the airflow delivery of the air separation device according to the collected parameters of millet humidity and light impurity content.

[0098] The detection and control system adopts a closed-loop architecture of "monitoring-processing-control-interaction". All components and parts are made of industrial-grade equipment to ensure stable operation in the dusty and vibrating environment of Xiaomi's processing workshop.

[0099] The parameter monitoring module includes a Xiaomi humidity sensor and a light impurity content sensor. The Xiaomi humidity sensor is a temperature and humidity integrated sensor of model SHT35-060, which is installed at the outlet of the feeding section 3 of the Xiaomi Selected bracket 1 and one sensor is configured for each feeding channel. It can collect the relative humidity of falling Xiaomi in real time, with a measurement range covering 0-100%RH and an accuracy controlled within ±2%RH.

[0100] The light impurity content sensor uses a CNY70 infrared reflective sensor, which is installed in the middle of the inclined surface of the V-shaped material guide sorting column 9 with one sensor on each side. It identifies light impurities such as rice husks and dust by the difference in infrared reflectivity, and the measurement range is 0-10%, thereby detecting the proportion of light impurities in millet.

[0101] The data processing module consists of an industrial-grade microcontroller and a data storage unit. The industrial-grade microcontroller uses an STM32F407ZGT6 chip and is installed in the waterproof and dustproof control box on the side of the Xiaomi Selected Stand 1 (or integrated or installed on other equipment in the Xiaomi production line, including sensors for detecting humidity and impurity content in Xiaomi products; these sensors can also be installed on other equipment in the Xiaomi production line, as long as they can perform accurate detection; no specific limitations are made here). It can receive analog signals from the parameter monitoring module and convert them into digital signals. After calculation and analysis, it compares the signals with preset thresholds to generate control commands.

[0102] The data storage unit uses a 16GB industrial-grade SD card, which is integrated with the microcontroller in the same control box. It can store humidity, impurity content data and equipment operation logs for 24 hours, facilitating subsequent traceability and parameter optimization.

[0103] The execution control module includes a relay module and a telescopic cylinder controller. The relay module uses a G6K-2P-Y8-channel relay, which is installed in the control box and electrically connected to the microcontroller. It can receive commands from the microcontroller to control the on / off state of the hot / cold air switching valve of the external air source and the solenoid valve of the air supply hose 20. The telescopic cylinder controller uses an EC-100 DC 24V controller, which is integrated into the junction box of the interval adjustment telescopic cylinder 21 and the adjustment telescopic cylinder 5 respectively. After receiving the PWM signal from the microcontroller, it can accurately control the telescopic cylinder extension and retraction, with a control accuracy of ±1mm, so as to realize the adjustment of the spacing of the sorting inclined plate 13 and the size of the discharge port 14.

[0104] The human-machine interaction module consists of an industrial touch screen and an alarm buzzer. The industrial touch screen is a TK6071iP 7-inch color touch screen, which is installed on the operation control cabinet of Xiaomi's processing production line. It can display real-time humidity and impurity content data, and supports manual setting of parameter thresholds, starting and stopping of equipment, and fault alarm prompts (such as sensor disconnection, telescopic cylinder jamming).

[0105] The alarm buzzer is an LTE-1101J24V buzzer, which is installed on the top of the control cabinet. When the humidity / impurity content exceeds the safe range or the equipment malfunctions, it will emit an 85dB audible and visual alarm. The alarm duration can be set via the touch screen.
