Description

Technical Field

[0001] This invention belongs to the field of beverage production technology and relates to a weighing device, specifically a device for accurately weighing ingredients for tremella beverages. Background Technology

[0002] In the food industry, especially in the production of high-end tremella beverages, the accurate and efficient addition of various solid ingredients has always been a technical challenge. Existing technical solutions mainly suffer from the following shortcomings: First, traditional manual weighing or semi-automatic equipment is inefficient, relies on experience, and cannot remove defective products online, resulting in poor product consistency and large quality fluctuations. Existing equipment mostly adopts a static "weigh first, then place" mode, which is difficult to integrate into continuous production lines.

[0003] Secondly, existing automated equipment is usually only equipped with a single type of feeding mechanism (such as vibrating feeder), which is difficult to adapt to the characteristics of various materials with different particle sizes, shapes and degrees of fragility, such as goji berries, almonds and jujubes, resulting in unstable feeding accuracy or material breakage.

[0004] Finally, most systems are only open-loop control systems, lacking adaptive and learning capabilities. When the density and humidity of material batches change, manual shutdown is required to adjust parameters, making real-time closed-loop correction impossible and hindering the long-term stability and intelligence of production.

[0005] Therefore, we propose a precise weighing device for adding ingredients to tremella beverages. Summary of the Invention

[0006] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a precise weighing device for adding ingredients to tremella beverages. The technical problem this invention aims to solve is: how to upgrade accurate weighing into a complete intelligent system encompassing "feeding optimization, online verification, automatic sorting, and continuous self-adjustment" through mechatronics and software integration design.

[0007] The objective of this invention can be achieved through the following technical solutions: A precise weighing device for adding ingredients to a Tremella fuciformis beverage includes a main control unit, a feeding and conveying mechanism, several granule quantitative dispensing mechanisms, several vibrating quantitative discharging mechanisms, and several tilting quantitative discharging mechanisms. The feeding and conveying mechanism has several equidistantly distributed adjusting weighing mechanisms on its side. The upper end of each adjusting weighing mechanism has four circumferentially distributed weighing and dispensing mechanisms. The upper end of each adjusting weighing mechanism is sequentially divided into a feeding zone, a light material zone, a dispensing zone, and a heavy material zone. The dispensing zone is located on the side closest to the feeding and conveying mechanism, and the feeding zone is located on the side furthest from the feeding and conveying mechanism. The four weighing and dispensing mechanisms are respectively located in the feeding zone, the light material zone, the dispensing zone, and the heavy material zone. The total number of the particle quantitative feeding mechanism, the vibrating quantitative discharge mechanism, and the flipping quantitative discharge mechanism is the same as the number of the position adjustment weighing mechanism. The particle quantitative feeding mechanism, the vibrating quantitative discharge mechanism, and the flipping quantitative discharge mechanism are located above the weighing and feeding mechanism of the corresponding position adjustment weighing mechanism, away from the feeding conveyor mechanism. There are discharge conveyors on both sides of the position adjustment weighing mechanism. The two discharge conveyors are located below the weighing and feeding mechanisms of the light material area and the heavy material area, respectively. The main control board of the main control machine is equipped with a weighing module, a verification module, an adjustment module, a data management module, an equipment collaboration module, and a human-machine interaction module.

[0008] Working principle of the invention: 1. Preset: Based on the proportions of each ingredient in the white fungus beverage, the weight information is input through the human-computer interaction module and transmitted to the main control unit.

[0009] 2. Feeding: The material bowls are placed sequentially on the feeding conveyor and transported to the corresponding positions of several adjusting weighing mechanisms.

[0010] Small-sized ingredients for the Tremella beverage, such as goji berries, are fed into the granule metering feeding mechanism; medium-sized ingredients, such as almonds, are fed into the vibrating metering discharging mechanism; and large-sized ingredients, such as jujubes, are fed into the granule metering feeding mechanism. The particle quantitative feeding mechanism, vibration quantitative discharge mechanism and flipping quantitative discharge mechanism that are matched with the adjustment and weighing mechanism are started to feed the preset amount of material into the weighing and feeding mechanism located in the "feeding area".

[0011] 3. Verification and Judgment: The material falls into the weighing and feeding mechanism. The two sensors on the weighing and feeding mechanism work together to complete two weighings. At the same time, the weighing mechanism is adjusted to verify the weight.

[0012] The weighing information from the weighing and feeding mechanism and the adjusting weighing mechanism is transmitted to the weighing module. The weighing module analyzes the weight and transmits the analysis information to the verification module. The verification module compares the measured value with the target value and makes a judgment immediately. Acceptable: Weight is within the allowable tolerance range. Too light: Weight is below the lower limit. Too heavy: Weight is above the upper limit.

[0013] 4. Diversion Execution: The adjusting weighing mechanism drives the weighing and unloading mechanism carrying the material to rotate; Based on the verification results, the equipment coordination module controls the position weighing mechanism and the weighing unloading mechanism to perform different actions: Qualified: Continue rotating to the "discharge area", the weighing and discharging mechanism opens, and the qualified material is accurately put into the material bowl on the lower loading and conveying mechanism to complete the filling.

[0014] If the material is too light: it remains in the "light material zone". The weighing and feeding mechanism opens and discharges the unqualified material into the discharge conveyor on one side, returning it to the upstream process or treating it as waste.

[0015] Overweight: Rotate to the "heavy material zone", the weighing and unloading mechanism opens, and the unqualified material is discharged into the discharge conveyor on the other side.

[0016] 5. Intelligent Adjustment: When the verification module continuously detects systematic deviations in the material corresponding to a specific feeding mechanism, the adjustment module will be activated. The adjustment module analyzes the deviation data and automatically or prompts the operator to adjust the material quality of the corresponding feeding mechanism, or adjust parameters to correct the feeding quantity of the next batch of materials.

[0017] The main control unit integrates various software modules and coordinates the entire system. The weighing module acquires real-time weight data from each adjusting weighing mechanism and the weighing and unloading mechanism. The verification module quickly determines the material weight status and decides the material's destination. The adjustment module analyzes historical deviations and optimizes the unloading mechanism parameters to cope with material fluctuations. The data management module records all weighing results, deviations, and adjustment records for quality traceability and report analysis. The equipment coordination module precisely controls the start, stop, and timing of the conveying mechanism, unloading mechanism, weighing mechanism, and discharge mechanism to ensure smooth and error-free operation. The human-machine interface module provides operators with a status monitoring, parameter setting, alarm prompts, and report query interface.

[0018] The loading and conveying mechanism includes several conveying adjustment support rod seats, each with a mounting base fixed to its upper end. A conveying frame is mounted on the upper end of each mounting base. Symmetrically arranged side seats are fixed to both sides of the conveying frame, and adjusting seats are fixed to each side seat. A vertically arranged locking screw is screwed to the upper end of each adjusting seat. An adjusting support rod is slidably provided through the middle of the adjusting seat, and the adjusting support rod is horizontally positioned. The lower end of the locking screw abuts against the upper end of the adjusting support rod. Limiting side plates are provided at the ends of several adjusting support rods on the same side. A conveying chain is provided inside the conveying frame, and a conveying motor is fixed to the outer side of the conveying frame. The output shaft of the conveying motor is fixedly connected to one of the rotating shafts of the conveying chain.

[0019] With the above structure, when the conveyor motor starts, its output shaft drives one of the rotating shafts of the conveyor chain to rotate, thereby driving the conveyor chain to move. The rotating conveyor chain drives the material bowls on it to move linearly along the conveyor frame, passing under each adjusting and weighing mechanism in sequence.

[0020] When different sizes or models of material bowls need to be processed, the operator rotates the locking screw located on the upper end of the adjusting seat.

[0021] Loosen the locking screw so that its lower end is no longer tightly pressed against the adjusting strut. At this point, the adjusting strut can slide freely horizontally within the through hole of the adjusting seat.

[0022] The operator simultaneously moves the adjusting support rods on both sides of the conveyor frame, causing the limiting side plates fixed at their ends to move inward or outward, thereby changing the width of the channel between the two limiting side plates to match the width of the material bowl.

[0023] After adjusting to the appropriate width, retighten the locking screws on both sides. The lower end of the screw pushes down against the adjusting support rod, using friction to firmly fix it in the adjusting seat, thus completing the rigid locking of the entire width adjustment mechanism.

[0024] During equipment operation, the two limit side plates with locked widths form an accurate conveying channel. This ensures that each material bowl does not shift laterally or swing during conveying, and remains precisely aligned with the center of the adjusting weighing mechanism below its movement trajectory, providing a positional reference for the accurate feeding and weighing of subsequent materials.

[0025] The adjusting weighing mechanism includes an adjusting frame. Pressure sensors are fixed at the four corners of the lower end of the adjusting frame. A cam divider, an adjusting laser sensor, and several circumferentially distributed support seats are fixed at the upper end of the adjusting frame. The cam divider is located in the middle of the upper end of the adjusting frame. Several support seats are circumferentially distributed around the cam divider. The adjusting laser sensor is located on the outer side of the support seats. A cam motor is fixed at the lower end of the adjusting frame. The output shaft of the cam motor is connected to the input shaft of the cam divider. A rotating disk is fixed on the output shaft of the cam divider. Adjusting rods are adjustable at the upper ends of the support seats. Wheel seats are fixed at the upper ends of the adjusting rods. Support wheels are rotatably mounted on the upper ends of the wheel seats. The support wheels roll against the lower end face of the rotating disk. The feeding area, light material area, unloading area, and heavy material area are located on the upper end face of the rotating disk.

[0026] With the above structure, the initial state and load-bearing conditions are as follows: the weighing and feeding mechanism is placed in a designated area on the rotating disk. The weight of the material is transmitted through the rotating disk and support structure to the bottom adjustment frame, where it is sensed by four pressure sensors for weighing verification.

[0027] Command-driven and precise positioning: When materials need to be transferred to the next workstation, the equipment coordination module issues a command. The cam motor starts, driving the cam divider. The cam divider converts the continuous rotation of the cam motor into precise intermittent rotation of the output shaft. The rotating disk drives the weighing and unloading mechanism on it, rotating smoothly and accurately aligning with the next target workstation. A positioning laser sensor may be used to detect the reference position of the rotating disk or to perform auxiliary verification of the number of rotations / angles, ensuring accurate positioning.

[0028] Stable support and accurate weighing: The support wheels roll along with the rotating disk, reducing friction. After the rotating disk comes to a standstill, the support wheel system bears most of the structural weight, creating a stable measurement environment for the pressure sensor and avoiding mechanical stress interference, thus obtaining high-precision "verification weighing" data. The design of the adjusting rod allows for fine-tuning of the height of each support wheel, ensuring that the rotating disk is absolutely flat on the horizontal plane, which is crucial for ensuring weighing accuracy and smooth rotation.

[0029] The weighing and feeding mechanism includes a fixed ring, with three circumferentially distributed weighing and feeding frame rods fixed to the lower end of the fixed ring. Each weighing and feeding frame rod is equipped with a pressure sensor 2 at its lower end, which is located on the upper surface of the rotating disk. A reinforcing perforated plate is fixed between the lower halves of the three weighing and feeding frame rods. The lower end of the fixed ring is equipped with three circumferentially distributed weighing sensors, which correspond to the positions of the weighing and feeding frame rods. The weighing sensors are located on the inner side of the weighing and feeding frame rods at the same positions. The lower end of each device is connected to a side connecting rod. A discharge cone is fixed to the inner side of the three side connecting rods. The upper end of the discharge cone is higher than the upper end of the fixed ring. A tilting discharge valve is provided at the lower end of the discharge cone. A guide hopper is connected to the lower end of the tilting discharge valve. The guide hopper passes through the reinforcing perforated plate. A horizontally set guide pipe is provided at the lower end of the guide hopper. An air-filling valve is connected to the inner end of the guide pipe. An air-filling valve is connected to an air pump through a pipe. A discharge pipe is connected to the outer end of the guide pipe. The end of the discharge pipe extends out of the rotating disc.

[0030] Using the above structure, the feeding and initial weighing process involves the material falling into the feeding cone from the upper particle quantitative feeding mechanism, the vibrating quantitative discharge mechanism, and the tilting quantitative discharge mechanism. The weighing sensor immediately measures the net weight of the material, and this data, along with the total weight data measured by the pressure sensor, is sent to the weighing module for rapid analysis and pre-judgment.

[0031] Rotational Verification and Secondary Weighing: The entire mechanism rotates with the rotating disk to the "light material zone." In a stable, stationary state, the load cells perform a high-precision "verification weighing." At this time, data from pressure sensor two is used to compensate for and verify the mechanism's stability. The verification module makes a final judgment of "qualified, too light, or too heavy" based on the final accurate weight data.

[0032] Judgment Execution and Targeted Discharge: Based on the judgment, the rotating disc rotates the mechanism to the corresponding station. The equipment coordination module issues a command to open the tilting discharge valve. The material falls through the discharge cone and guide hopper into the guide pipe. The air supply valve is opened, and compressed air supplied by the air pump is blown into the guide pipe at high speed, allowing the material to be accurately discharged from the discharge pipe.

[0033] Emptying and cleaning: After the material is completely discharged, the tipping unloading valve is closed.

[0034] The granule metering feeding mechanism includes a fixed base. The upper end of the fixed base is detachably equipped with an adjusting electric push rod and an L-shaped unloading plate. The unloading plate has several metering feeding holes in the middle. The telescopic end of the adjusting electric push rod is fixed with a feeding ring seat. The feeding ring seat is square and is slidably set on the upper end face of the unloading plate. The length of the upper end face of the unloading plate is greater than twice the length of the feeding ring seat plus the sum of the maximum distances of the several metering feeding holes. The upper end of the feeding ring seat is equipped with a flexible hopper in the shape of a square frustum with a larger upper part and a smaller lower part.

[0035] Using the above structure, the operator sets the required material weight through the human-machine interface module. The equipment coordination module, based on this weight, finds the corresponding quantitative feeding hole from a pre-calibrated database. The module controls the precise extension and retraction of the electric push rod, pushing the feeding ring seat to slide on the unloading plate until the center of the square inner hole of the feeding ring seat is completely aligned with the center of the target quantitative feeding hole. At this point, the inner frame of the feeding ring seat covers and exclusively opens the target hole, while all other holes are closed by their bases. Small particles of material in the flexible hopper flow downwards under gravity. Because the feeding ring seat only opens the preset quantitative feeding hole, the material can only fall through this hole. After the material fills the entire volume of the hole, excess material is blocked by the feeding ring seat base. When the weighing and feeding mechanism is in place, the entire fixed volume of material in the hole falls into the container below by gravity. One feeding action is completed; adjusting the electric push rod can reset or maintain its position to prepare for the next feeding of the same weight. When it is necessary to change the feeding weight, adjust the electric push rod to move the feeding ring seat to align with another quantitative feeding hole of different volume, and output a new preset weight.

[0036] The vibratory quantitative discharge mechanism includes a vibratory plate, with a discharge ring groove at the upper end of the vibratory plate. The discharge end of the discharge ring groove is connected to a discharge chute that communicates with it. A limiting electric push rod is provided on the side of the discharge chute, and the telescopic end of the limiting electric push rod extends through into the interior of the discharge chute.

[0037] Using the above structure, preparation and sorting are as follows: The vibratory feeder is started, generating micro-vibrations of a specific frequency and amplitude. Under the action of vibration, the material in the feeder climbs upward along the spiral track inside the feeder, automatically arranging itself in a single layer and adjusting its direction during the process, forming a continuous and orderly single-line queue, which then enters the discharge ring trough in sequence.

[0038] Uniform feeding: An orderly flow of material flows from the discharge ring trough into the discharge chute. At this time, the telescopic end of the limiting electric push rod is in the "retracted" state, and the material can pass through the end of the chute without obstruction and fall freely into the weighing and feeding mechanism below.

[0039] Dynamic Quantitative Feeding and Cut-off: After feeding begins, the system starts timing. When the feeding time calculated based on the preset weight and pre-calibrated material flow rate is reached, the module immediately sends a command to the limiting electric push rod. The telescopic end of the electric push rod quickly extends forward, directly inserting into and blocking the channel of the discharge chute, instantly cutting off the falling material flow. After being cut off, subsequent material is blocked behind the telescopic end, and the small amount of material that has already passed through the telescopic end but is still in the air falls into the weighing hopper, completing this quantitative feeding.

[0040] Reset and standby: After one feeding cycle is completed, the material limiting electric push rod retracts and the gate reopens, preparing for the next feeding cycle.

[0041] The flipping quantitative discharging mechanism includes a control box and a laser counter, a discharging sloping plate, a support, and a guide hopper fixed to the outside of the control box. The discharging sloping plate, the support, and the guide hopper are arranged in a sequentially inclined manner from bottom to top. The discharging sloping plate and the guide hopper are fixed to the upper two sides of the support. The upper surfaces of the discharging sloping plate and the guide hopper are coplanar. A semi-circular cavity is opened in the middle of the upper end of the support. A fixed frame, a flipping motor, and a counter are fixed inside the control box. A flipping shaft is rotatably mounted on the fixed frame. The outer end of the flipping shaft extends out of the control box, and a flipping discharging cylinder is fixed to the outer end of the flipping shaft. Several circumferentially distributed clamping holes are opened on the cylinder wall of the flipping discharging cylinder. The outer end face of the flipping discharging cylinder is open. The flipping discharging cylinder is located in the semi-circular cavity. The laser counter is located above the flipping discharging cylinder. A material-pushing planetary carrier is fixed to the inner end of the flipping shaft. A material-pushing rod is fixed to the output shaft of the flipping motor. The material-pushing rod and the material-pushing planetary carrier engage in a prying action.

[0042] Using the above structure, the preparation and gripping process is as follows: materials such as dates slide continuously and in a single layer through the guide hopper towards the side wall of the tilting discharge cylinder. The tilting motor starts, driving the tilting discharge cylinder to rotate slowly. When the clamping hole on the cylinder wall rotates to below the outlet of the guide hopper, a piece of material will fall into and stay in the hole, being "caught". A laser counter scans each clamping hole in real time. When material is detected in the hole, it counts once; if an empty hole is detected, the system records that the hole failed to be filled.

[0043] Counting Verification: The roller rotates continuously for one or several revolutions until all preset clamping holes are filled, or until the laser counter reaches the target number of materials required, at which point the gripping phase stops. This process ensures that each batch of material is accurate in quantity, which is a prerequisite for accurate weight.

[0044] Tilting and Unloading: After loading and counting verification are completed, the equipment coordination module issues an unloading command. The output shaft of the tilting motor drives the material feeding rod to rotate, which in turn drives the planetary material feeding carrier to rotate, thereby driving the tilting shaft to rotate. The tilting shaft drives the tilting discharge cylinder to rotate rapidly. During the tilting process, the clamping holes and the material inside, which were originally located at the bottom of the cylinder, are rotated to the top. Since one end of the cylinder is open, all the material is poured out from the open end in one go under the action of gravity. The poured material falls onto the discharge sloping plate and slides down the slope into the weighing and unloading mechanism below.

[0045] Reset: After unloading is completed, the discharge cylinder is flipped back to its original position to prepare for the next cycle of gripping.

[0046] The weighing module includes a data acquisition unit, a data processing unit, and a weighing control unit; the verification module includes a standard value management unit, a real-time comparison unit, a decision logic unit, and an SPC statistical unit; the adjustment module includes a deviation analysis unit, a parameter optimization unit, an adaptive learning unit, and an adjustment execution unit; the data management module includes a real-time database unit, a historical data archiving unit, a traceability management unit, and a report generation unit; the equipment collaboration module includes a timing control unit, a status monitoring unit, a communication management unit, and an anomaly handling unit; and the human-machine interaction module includes a user interface unit, a recipe management unit, an alarm display unit, a remote access unit, and a training and assistance unit.

[0047] Compared with existing technologies, this precise weighing device for adding ingredients to white fungus beverages has the following advantages: This invention adopts a closed-loop sorting mechanism of "rotation verification and physical partitioning". The weighing unit is driven to rotate precisely between four stations by a cam divider, which converts the weight judgment into physical position, realizes online, automatic and non-destructive rejection of defective products, and ensures the weight qualification rate of the output materials.

[0048] This invention constructs a complete data intelligence closed loop of "perception-decision-execution-optimization". The six major software modules work together to not only control in real time, but also analyze historical data by adjusting the modules, learn from it, and optimize the feeding parameters in reverse, enabling the equipment to proactively adapt to material fluctuations and upgrade from an automated machine to an intelligent production unit.

[0049] This invention enables flexible, high-precision production. It integrates three metering mechanisms—particle control, vibration, and tilting—to optimize the feeding strategy from the source, catering to different material characteristics. Through redundant weighing verification and pneumatic cleaning design, it ultimately ensures comprehensive accuracy, long-term stability, and production efficiency. Attached Figure Description

Detailed Implementation

[0062] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0063] like Figures 1-11As shown, this precise weighing device for adding ingredients to a white fungus beverage includes a main control unit, a feeding and conveying mechanism 1, several granule quantitative dispensing mechanisms 5, several vibrating quantitative dispensing mechanisms 6, and several flipping quantitative dispensing mechanisms 7. The feeding and conveying mechanism 1 has several equidistantly distributed adjusting weighing mechanisms 3 on its side. The upper end of each adjusting weighing mechanism 3 has four circumferentially distributed weighing and dispensing mechanisms 4. The upper end of each adjusting weighing mechanism 3 is circumferentially divided into a feeding zone, a light material zone, a dispensing zone, and a heavy material zone. The dispensing zone is located closer to the feeding and conveying mechanism 1, and the feeding zone is located further away from the feeding and conveying mechanism 1. The four weighing and dispensing mechanisms 4 are located in the feeding zone, light material zone, dispensing zone, and heavy material zone, respectively. In the material area, the sum of the number of the granule quantitative feeding mechanism 5, the vibrating quantitative discharge mechanism 6, and the flipping quantitative discharge mechanism 7 is the same as the number of the position adjustment weighing mechanism 3. The granule quantitative feeding mechanism 5, the vibrating quantitative discharge mechanism 6, and the flipping quantitative discharge mechanism 7 are located above the weighing and feeding mechanism 4 in the feeding area of ​​the corresponding position adjustment weighing mechanism 3, away from the feeding conveying mechanism 1. Discharge conveyors are provided on both sides of the position adjustment weighing mechanism 3. The two discharge conveyors are located below the weighing and feeding mechanisms 4 in the light material area and the heavy material area, respectively. The main control board of the main control machine is equipped with a weighing module, a verification module, an adjustment module, a data management module, an equipment collaboration module, and a human-machine interaction module.

[0064] 1. Preset: Based on the proportions of each ingredient in the white fungus beverage, the weight information is input through the human-computer interaction module and transmitted to the main control unit.

[0065] 2. Feeding: The material bowls 2 are placed on the feeding conveyor 1 in sequence and run on it, and are conveyed to the corresponding positions of several adjusting weighing mechanisms 3 in sequence.

[0066] Small-sized ingredients for the Tremella beverage, such as goji berries, are fed into the particle quantitative feeding mechanism 5. Medium-sized ingredients, such as almonds, are fed into the vibrating quantitative discharging mechanism 6. Large-sized ingredients, such as jujubes, are fed into the tilting quantitative discharging mechanism 7. The particle quantitative feeding mechanism 5, the vibration quantitative discharge mechanism 6, and the flipping quantitative discharge mechanism 7, which are matched with the adjustment and weighing mechanism 3, are activated to feed a preset amount of material into the weighing and feeding mechanism 4 located in the "feeding area".

[0067] 3. Verification and Judgment: The material falls into the weighing and feeding mechanism 4. The two sensors on the weighing and feeding mechanism 4 work together to complete two weighings. At the same time, the weighing mechanism 3 is adjusted to verify the weight.

[0068] The weighing information from the weighing and unloading mechanism 4 and the adjusting weighing mechanism 3 is transmitted to the weighing module. The weighing module analyzes the weight and transmits the analysis information to the verification module. The verification module compares the measured value with the target value and makes a judgment immediately. Acceptable: Weight is within the allowable tolerance range. Too light: Weight is below the lower limit. Too heavy: Weight is above the upper limit.

[0069] 4. Diversion execution: The adjusting weighing mechanism 3 drives the weighing and unloading mechanism 4, which carries the material, to rotate; Based on the verification results, the equipment coordination module controls the position weighing mechanism 3 and the weighing and unloading mechanism 4 to perform different actions: Qualified: Continue rotating to the "discharge area", the weighing and discharging mechanism 4 opens, and the qualified material is accurately put into the material bowl 2 on the lower loading and conveying mechanism 1 to complete the filling.

[0070] If the material is too light: it remains in the "light material zone". The weighing and feeding mechanism 4 opens and discharges the unqualified material into the discharge conveyor on one side, returning it to the upstream process or treating it as waste.

[0071] Overweight: Rotate to the "heavy material zone", the weighing and unloading mechanism 4 opens, and the unqualified material is discharged into the discharge conveyor on the other side.

[0072] 5. Intelligent Adjustment: When the verification module continuously detects a systematic deviation (such as consistently underweight) in the material corresponding to a specific feeding mechanism (e.g., granule quantitative feeding mechanism 5), the adjustment module will be activated. The adjustment module analyzes the deviation data and automatically or prompts the operator to adjust the material quality of the corresponding feeding mechanism, or adjust parameters (such as feeding time, vibration frequency, and flipping angle) to correct the feeding quantity of the next batch of material.

[0073] The main control unit integrates various software modules and coordinates the entire system. The weighing module acquires real-time weight data from each adjusting weighing mechanism 3 and the weighing and unloading mechanism 4. The verification module quickly determines the material weight status and decides the material's destination. The adjustment module analyzes historical deviations and optimizes the unloading mechanism parameters to cope with material fluctuations. The data management module records all weighing results, deviations, and adjustment records for quality traceability and report analysis. The equipment coordination module precisely controls the start, stop, and timing of the conveying mechanism, unloading mechanism, weighing mechanism, and discharge mechanism to ensure smooth and error-free operation. The human-machine interface module provides operators with a status monitoring, parameter setting, alarm prompts, and report query interface.

[0074] The loading and conveying mechanism 1 includes several conveying adjustment support rod seats 8. Each of the several conveying adjustment support rod seats 8 has a mounting seat 9 fixed at its upper end. Each of the mounting seats 9 has a conveying frame at its upper end. The two sides of the conveying frame are fixed with symmetrically arranged side seats 11. Each side seat 11 is fixed with an adjusting seat 12. The upper end of the adjusting seat 12 is screwed with a vertically arranged locking screw 13. The middle of the adjusting seat 12 is slidably provided with an adjusting support rod 14 that passes through it. The adjusting support rod 14 is horizontally arranged. The lower end of the locking screw 13 abuts against the upper end of the adjusting support rod 14. The ends of several adjusting support rods 14 on the same side are provided with limiting side plates 15. The inner side of the conveying frame is provided with a conveying chain 10. The outer side of the conveying frame is fixed with a conveying motor 16. The output shaft of the conveying motor 16 is fixedly connected to one of the rotating shafts of the conveying chain 10.

[0075] The conveyor motor 16 starts, and its output shaft drives one of the rotating shafts of the conveyor chain 10 to rotate, thereby driving the conveyor chain 10 to move. The rotating conveyor chain 10 drives the material bowl 2 on it to move linearly along the conveyor frame, passing under each adjusting weighing mechanism 3 in sequence. When it is necessary to process material bowls of different sizes or models, the operator rotates the locking screw 13 located at the upper end of the adjusting seat 12. Loosening the locking screw 13 so that its lower end is no longer tightly pressed against the adjusting support rod 14. At this time, the adjusting support rod 14 can slide freely horizontally in the through hole of the adjusting seat 12. The operator simultaneously moves the adjusting support rods 14 on both sides of the conveyor frame, causing the limiting side plates 15 fixed at their ends to move inward or outward, thereby changing the width of the channel between the two limiting side plates 15 to match the width of the material bowl 2. After adjusting to the appropriate width, the locking screws 13 on both sides are tightened again. The lower end of the screw presses down against the adjusting support rod 14, using friction to firmly fix it in the adjusting seat 12, completing the rigid locking of the entire width adjustment mechanism. During equipment operation, the two limit side plates 15 with locked width form an accurate conveying channel. This ensures that each material bowl 2 does not shift laterally or swing during conveying, and is always precisely aligned with the center of the adjusting weighing mechanism 3 below its movement trajectory, providing a positional reference for the accurate feeding and weighing of subsequent materials.

[0076] The adjusting weighing mechanism 3 includes an adjusting frame 18. Pressure sensors 17 are fixed at each of the four corners of the lower end of the adjusting frame 18. A cam divider 24, an adjusting laser sensor 19, and several circumferentially distributed support seats 20 are fixed at the upper end of the adjusting frame 18. The cam divider 24 is located in the middle of the upper end of the adjusting frame 18, and the support seats 20 are evenly distributed around the cam divider 24. The adjusting laser sensor 19 is located on the outside of the support seats 20. A convex... The output shaft of the wheel motor 26 and the cam motor 26 are connected to the input shaft of the cam divider 24. A rotating disk 25 is fixed on the output shaft of the cam divider 24. An adjusting rod 21 is adjustablely provided on the upper end of the support base 20. A wheel seat 23 is fixed on the upper end of the adjusting rod 21. A support wheel 22 is rotatably provided on the upper end of the wheel seat 23. The support wheel 22 rolls against the lower end surface of the rotating disk 25. The feeding area, light material area, unloading area and heavy material area are set on the upper end surface of the rotating disk 25.

[0077] The weighing and unloading mechanism 4, which carries the material, is precisely rotated to one of the four predetermined positions of "feeding, light material, unloading, and heavy material" according to instructions, while providing accurate weight data.

[0078] Weighing system: Composed of four pressure sensors 17 at the bottom, used to sense the total weight change of the entire mechanism (including the rotating disk 25, the material on it and the weighing and feeding mechanism 4).

[0079] Rotary drive and indexing system: The cam motor 26 drives the cam divider 24, which in turn drives the rotating disk 25 to perform precise intermittent rotation (90° each time).

[0080] The stabilizing support system consists of a support base 20, an adjusting rod 21, a wheel seat 23, and a support wheel 22. It is used to provide stable and adjustable auxiliary support for the rotating disk 25 when it is rotating and stationary, so as to ensure the stability of the weighing.

[0081] Initial state and load: The weighing and feeding mechanism 4 (containing the material to be tested) is placed in a designated area (such as the feeding area) on the rotating disk 25.

[0082] The weight of the material is transmitted through the rotating disk 25 and the support structure to the bottom adjustment frame 18, where it is sensed by four pressure sensors 17 to verify the weight.

[0083] Command-driven and precise positioning: When it is necessary to move materials to the next workstation (such as from the "feeding area" to the "light material area"), the equipment coordination module issues a command.

[0084] The cam motor 26 starts and drives the cam divider 24. The cam divider 24 converts the continuous rotation of the cam motor 26 into accurate intermittent rotation of the output shaft (i.e., the rotating disk 25).

[0085] The rotating disk 25 drives the weighing and feeding mechanism 4 on it to rotate smoothly by 90 degrees and accurately align with the next target station (such as the discharge port of the light material area or the top of the material bowl in the feeding area).

[0086] The positioning laser sensor 19 may be used to detect the reference position of the rotating disk or to perform auxiliary verification of the number of rotations / angles to ensure accurate positioning.

[0087] Stable support and accurate weighing: The support wheels 22 roll along with the rotating disk 25, reducing friction. After the rotating disk 25 is stationary, the support wheel system bears most of the structural weight, creating a stable measurement environment for the pressure sensor 17, avoiding mechanical stress interference, and thus obtaining high-precision "verification weighing" data. The design of the adjusting rod 21 allows for fine adjustment of the height of each support wheel 22, ensuring that the rotating disk 25 is absolutely flat on the horizontal plane, which is crucial for ensuring weighing accuracy and smooth rotation.

[0088] The weighing and feeding mechanism 4 includes a fixed ring 29. Three circumferentially distributed weighing and feeding support rods 28 are fixed to the lower end of the fixed ring 29. Each weighing and feeding support rod 28 has a pressure sensor 27 at its lower end, which is located on the upper surface of the rotating disk 25. A reinforcing perforated plate 36 is fixed between the lower halves of the three weighing and feeding support rods 28. Three circumferentially distributed weighing sensors 30 are located at the lower end of the fixed ring 29. The weighing sensors 30 correspond to the positions of the weighing and feeding support rods 28 and are located inside the weighing and feeding support rods 28 at the same position. Each of the three side connecting rods 31 is connected to a side connecting rod 31. A discharge cone 32 is fixed to the inner side of the three side connecting rods 31. The upper end of the discharge cone 32 is higher than the upper end of the fixing ring 29. A tilting discharge valve 34 is provided at the lower end of the discharge cone 32. A guide hopper 35 is connected to the lower end of the tilting discharge valve 34. The guide hopper 35 passes through the reinforcing perforated plate 36. A horizontally arranged guide pipe is provided at the lower end of the guide hopper 35. An air-filling valve 33 is connected to the inner end of the guide pipe. An air-filling valve 33 is connected to an air pump through a pipe. A discharge pipe 37 is connected to the outer end of the guide pipe. The end of the discharge pipe 37 extends out of the rotating disk 25.

[0089] Dual-redundant weighing system: Static reference weighing, with three pressure sensors 27 supporting the entire mechanism on a rotating disk 25, primarily measuring the "tare weight" (i.e., the weight when unloaded), serving as the static reference point for the entire weighing system. Dynamic net weight weighing, with three weighing sensors 30 suspended from a discharge cone 32. When material falls into the discharge cone 32, its weight is directly sensed by these three sensors, measuring the net weight of the material. This design, combined with bottom sensors, enables high-precision, interference-resistant net weight measurement.

[0090] Feeding and initial weighing: Material falls from the upper particle quantitative feeding mechanism 5, the vibrating quantitative discharge mechanism 6, and the tilting quantitative discharge mechanism 7 into the feeding cone 32. The weighing sensor 30 immediately measures the net weight of the material. This data (net weight) and the total weight data measured by the pressure sensor 27 are sent to the weighing module for rapid analysis and pre-judgment.

[0091] Rotational Verification and Secondary Weighing: The entire mechanism rotates with the rotating disk 25 to the "light material zone." In a stable, stationary state, the load cell 30 performs a high-precision "verification weighing." At this time, data from the second pressure sensor 27 is used to compensate for and verify the stability of the mechanism; that is, the second pressure sensor 27 and the load cell 30 work together to complete two weighings. The verification module makes a final judgment of "qualified, too light, or too heavy" based on the final accurate weight data.

[0092] Judgment Execution and Directional Discharge: Based on the judgment result, the rotating disc rotates the mechanism to the corresponding station (qualified → unloading area; too light → light material area; too heavy → heavy material area). The equipment coordination module issues a command, and the tilting unloading valve 34 opens. The material falls into the guide pipe through the unloading cone 32 and the guide hopper 35. The air supply valve 33 is opened, and compressed air supplied by the air pump is blown into the guide pipe at high speed. The material is accurately discharged from the discharge pipe 37. After the material is discharged, the tilting unloading valve 34 closes.

[0093] The pellet quantitative feeding mechanism 5 includes a fixed base 38. The upper end of the fixed base 38 is detachably provided with an adjusting electric push rod 43 and an L-shaped unloading plate 39. The unloading plate 39 has several quantitative feeding holes 40 in the upper middle part. The telescopic end of the adjusting electric push rod 43 is fixed with a feeding ring seat 41. The feeding ring seat 41 is square ring-shaped and is slidably disposed on the upper end surface of the unloading plate 39. The length of the upper end surface of the unloading plate 39 is greater than twice the length of the feeding ring seat 41 and the sum of the maximum distances of the several quantitative feeding holes 40. The upper end of the feeding ring seat 41 is provided with a flexible hopper 42 in the shape of a square frustum with a larger upper part and a smaller lower part.

[0094] The operator sets the desired material weight (e.g., 8 grams of goji berries) via the human-machine interface module. Based on this weight, the equipment coordination module retrieves the corresponding quantitative feeding hole 40 (e.g., calibrated for 8 grams) from a pre-defined database. The module then controls the precise extension and retraction of the electric push rod 43, pushing the feeding ring seat 41 to slide on the unloading tray until the center of the square inner hole of the feeding ring seat is perfectly aligned with the center of the target quantitative feeding hole. At this point, the inner frame of the feeding ring seat 41 covers and exclusively opens the target hole, while all other holes are closed by their base.

[0095] Small particles in the flexible hopper 42 flow downwards under gravity. Since the feeding ring seat 41 only opens the preset quantitative feeding hole 40, the material can only fall through this hole. After the material fills the entire volume of the hole, excess material is blocked by the feeding ring seat base. When the weighing and feeding mechanism 4 is in place, the entire fixed volume of material in the hole falls into the container below by gravity. Once one feeding action is completed, the adjusting electric push rod 43 can reset or maintain its position to prepare for the next feeding of the same weight.

[0096] When it is necessary to change the feeding weight (such as changing the product formula), adjust the electric push rod 43 to move the feeding ring seat 41 to align with another quantitative feeding hole 40 of different volume, and a new preset weight can be output.

[0097] The vibrating quantitative discharge mechanism 6 includes a vibrating plate 44. The upper end of the vibrating plate 44 is provided with a discharge ring groove 45. The discharge end of the discharge ring groove 45 is connected to a discharge inclined groove 46. The side of the discharge inclined groove 46 is provided with a limiting electric push rod 47. The telescopic end of the limiting electric push rod 47 extends through into the interior of the discharge inclined groove 46.

[0098] Preparation and sorting: The vibratory feeder 44 is started, generating micro-vibrations of a specific frequency and amplitude. Under the action of vibration, the material (such as almonds) in the feeder climbs upward along the spiral track inside the feeder, and automatically arranges itself in a single layer and adjusts its direction during the process, forming a continuous and orderly single-line formation, which then enters the discharge ring trough 45 in sequence.

[0099] Uniform feeding: An orderly flow of material flows from the discharge ring trough 45 into the discharge chute 46. At this time, the telescopic end of the limiting electric push rod 47 is in the "retracted" state, and the material can pass through the end of the chute without obstruction and fall freely into the weighing and feeding mechanism 4 below.

[0100] Dynamic Quantification and Cut-off: After feeding begins, the system (equipment coordination module) starts timing. When the feeding time calculated based on the preset weight and pre-calibrated material flow rate is reached, the module immediately sends a command to the limiting electric push rod 47. The telescopic end of the electric push rod quickly extends forward, directly inserting into and blocking the channel of the discharge chute 46, instantly cutting off the falling material flow. After being cut off, subsequent material is blocked behind the telescopic end, and the small amount of material that has already passed through the telescopic end but is still in the air falls into the weighing hopper, completing this quantitative feeding.

[0101] Reset and standby: After one feeding cycle is completed, the material limiting electric push rod 47 retracts and the gate reopens, preparing for the next feeding cycle.

[0102] The tilting quantitative discharge mechanism 7 includes a control box 52 and a laser counter 54, a discharge sloping plate 48, a support 49, and a guide hopper 51 fixed to the outside of the control box 52. The discharge sloping plate 48, the support 49, and the guide hopper 51 are arranged in a sequentially inclined manner from bottom to top. The discharge sloping plate 48 and the guide hopper 51 are fixed to the upper ends of the support 49 on both sides. The upper surfaces of the discharge sloping plate 48 and the guide hopper 51 are coplanar. A semi-circular cavity is formed in the middle of the upper end of the support 49. The control box 52 contains a fixing frame 53, a tilting motor 55, and a counter 57. The 3 is equipped with a rotating rotating shaft 56, the outer end of which extends out of the control box 52, and a rotating discharge cylinder 50 is fixed to the outer end of the rotating shaft 56. Several circumferentially distributed clamping holes are opened on the cylinder wall of the rotating discharge cylinder 50. The outer end face of the rotating discharge cylinder 50 is open. The rotating discharge cylinder 50 is located in a semi-arc cavity. The laser counter 54 is located above the rotating discharge cylinder 50. A feeding planetary carrier 58 is fixed to the inner end of the rotating shaft 56. A feeding rod 59 is fixed on the output shaft of the rotating motor 55. The feeding rod 59 and the feeding planetary carrier 58 are engaged in a feeding action.

[0103] Preparation and Grabbing (Filling Stage): Materials such as dates slide continuously and in a single layer through the guide hopper 51 towards the side wall of the tilting discharge cylinder 50. The tilting motor 55 starts, driving the tilting discharge cylinder 50 to rotate slowly. When the clamping hole on the cylinder wall rotates to below the outlet of the guide hopper, a piece of material falls into and remains inside the hole, being "caught". The laser counter 54 scans each passing clamping hole in real time. When material is detected in the hole, a count is made; if an empty hole is detected, the system records that the hole failed to be filled.

[0104] Counting Verification (Ensuring Quantity): The roller rotates continuously for one or several cycles until all preset clamping holes are filled, or until the value of laser counter 54 reaches the target based on the preset required number of materials, at which point the gripping phase stops. This process ensures that each batch of material is accurate in quantity, which is a prerequisite for accurate weight.

[0105] Tilting and Unloading (Dispensing Stage): After filling and counting verification are completed, the equipment coordination module issues an unloading command. The output shaft of the tilting motor 55 drives the material feeding rod 59 to rotate, which in turn drives the material feeding planetary carrier 58 to rotate, thereby driving the tilting shaft 56 to rotate. The tilting shaft 56 drives the tilting discharge cylinder 50 to rotate rapidly. During the tilting process, the clamping hole and the material inside, which were originally located at the bottom of the cylinder, are rotated to the top. Since one end of the cylinder is open, all the material is poured out from the open end in one go under the action of gravity. The poured material falls on the discharge sloping plate 48 and slides down the slope into the weighing and dispensing mechanism 4 below.

[0106] Reset: After unloading is completed, the discharge cylinder is flipped 50 degrees back to its original position to prepare for the next cycle of gripping.

[0130] The training and help section provides operation guidance and training support, operation procedure guidance, troubleshooting wizards, equipment maintenance reminders, and online help documents.

[0131] Working principle of the invention: Phase 1: Initialization and Preset (System Preparation) Recipe Loading: Operators select or create product recipes through the graphical interface of the Human-Machine Interface (HMI). The recipe not only includes the target weight of each ingredient such as goji berries, almonds, and dates, but more importantly, it includes: Tolerance range: Allowable upper and lower deviations (e.g., ±0.5g).

[0132] Control parameters: Pre-calibrated feeding parameters that match the current material batch (such as feed hole number, vibrating feed time, and number of items gripped by the tilting drum).

[0133] Correlationship: The correspondence between the formula and specific workstations and feeding mechanisms on the production line.

[0134] Parameter distribution: The main control unit decomposes the formula parameters and distributes them to the corresponding modules. The equipment coordination module pre-sets the execution parameters of the granule quantitative feeding mechanism 5, the vibrating quantitative discharging mechanism 6, and the flipping quantitative discharging mechanism 7 according to the formula; the weighing module and the verification module load the target values ​​and tolerances, preparing for verification.

[0135] Phase Two: Synchronous Feeding and Initial Weighing (Process Start-up) Container positioning: The loading conveyor 1 starts, and the material bowl 2 moves accurately within the adjustable-width guide channel. When the material bowl reaches directly below the first adjusting weighing mechanism 3, the conveyor belt pauses or synchronizes with the weighing cycle.

[0136] Parallel feeding: Based on the formula, the system simultaneously (or with a very small time difference) triggers the three feeding mechanisms at the corresponding workstations. Granulation mechanism (goji berries): The electric push rod 43 is pre-positioned so that the only opening of the feeding ring seat 41 is aligned with the preset weight quantitative feeding hole 40. The material falls after filling the volume of the hole by gravity.

[0137] Vibration Mechanism (Almond): Vibratory feeder 44 operates continuously, ensuring orderly material arrangement. The limiting electric push rod 47 remains retracted (channel open). The system calculates the theoretical feeding time T based on the target weight and calibrated flow rate. Upon reaching time T, the limiting electric push rod 47 instantly extends to cut off the material flow.

[0138] Tilting Mechanism (Jujube): The tilting discharge cylinder 50 has completed filling and laser counter 54 verification in the previous cycle to ensure accurate counting of materials inside the cylinder. Upon receiving the instruction, the tilting motor 55 drives the cylinder to quickly tilt 180 degrees, dumping out the entire batch of material.

[0139] Initial data fusion: All materials converge into the discharge cone 32 of the weighing and discharging mechanism 4. At this point: The load cell 30 of the suspended cone immediately measures the preliminary value M1 of the material's net weight.

[0140] The pressure sensor 27, which supports the entire weighing and feeding mechanism 4, measures the total value including the tare weight of the mechanism itself.

[0141] The weighing module's data processing unit operates in real time: Net weight = Weighing sensor 30 reading - Zero point calibration value; Tare weight verification = Pressure sensor 27 reading - Weighing sensor 30 reading - Known tare weight of the mechanism. This step is used for cross-validation to prevent single sensor failure. The initial weight M1 and status flag are sent to the verification module for pre-analysis.

[0142] Phase Three: Rotation Verification and Final Judgment (Quality Adjudication) Rotational Positioning: The equipment coordination module instructs the cam motor 26 of the weighing mechanism 3 to start. The cam divider 24 drives the rotating disk 25, which in turn drives the weighing and unloading mechanism 4 on it to rotate precisely 90 degrees from the "feeding area" to the "light material area". The cam divider ensures the rigidity and accuracy of the mechanical positioning, and the positioning laser sensor 19 provides position feedback to achieve closed-loop control.

[0143] Stability and Accuracy: After rotation stops, the support wheel 22 system bears most of the mechanical structure weight, providing a stable measurement environment free from stress interference for the pressure sensor 17 at the bottom. The system waits for a preset stabilization time (e.g., 200ms) until the weight reading is completely stable.

[0144] Dual-verification weighing: Main verification: The weighing and feeding mechanism 4 uses its own weighing sensor 30 to perform high-precision sampling in a static state to obtain the final net weight value M2. The weighing sensor 30 and the pressure sensor 17 work together to perform two weighings.

[0145] Auxiliary verification: The pressure sensor 17 of the position weighing mechanism 3 reads the total weight including the rotary table, weighing mechanism and material. By subtracting the calibrated system tare weight, the material weight M2' is calculated in reverse, and M2 is verified.

[0146] Intelligent decision: The decision logic unit of the verification module receives M2 and M2'.

[0147] Data reliability check: First, determine whether the difference between M2 and M2' is within a reasonable range. If it exceeds the range, it is determined that the sensor is abnormal, triggering an alarm and entering the abnormal handling process.

[0148] Qualification judgment: If the data is reliable, then compare M2 with the target value T.

[0149] If |M2-T|≤ permissible error, the judgment is "qualified".

[0150] If M2-T <- allowable error, the judgment is "too lenient".

[0151] If M2-T > + allowable error, the judgment is "too heavy".

[0152] Trend recording: The results (including weight value, deviation value, and decision) are sent to the data management module for storage in real time and used by the SPC statistical unit to update the control chart.

[0153] Phase Four: Judgment Execution and Physical Triage (Action Execution) Path selection and rotation: Based on the decision result, the device coordination module issues a second rotation command.

[0154] The judgment is "qualified": the cam motor drives the rotating disk to rotate another 90 degrees to the "discharge area". At this time, the outlet of the discharge pipe 37 of the weighing and discharging mechanism 4 is aligned with the material bowl 2 on the conveyor belt below.

[0155] The judgment was "too lenient": the rotary table remained stationary in the "light material zone." The outlet of discharge pipe 37 was aligned with the discharge conveyor on the left.

[0156] The judgment is "overweight": the turntable is rotated another 90 degrees (i.e., from the light material zone to the "heavy material zone"). The outlet of discharge pipe 37 is aligned with the discharge conveyor on the right.

[0157] After positioning is completed, the equipment coordination module triggers the opening of the tilting unloading valve 34.

[0158] The material enters the feed pipe through the feed hopper 35. At the same time, the air valve 33 opens instantly, injecting compressed air to create pneumatic pushing, ensuring that the material is completely and quickly blown out of the discharge pipe 37 without any residue.

[0159] After unloading is complete, the valve is closed, and the mechanism is ready for the next cycle.

[0160] Phase 5: Data Closure and Adaptive Optimization (System Evolution) Data aggregation: The data management module fully records all data for this cycle: parameters of each feeding mechanism, initial weight M1, final weight M2, judgment result, timestamp, workstation number, etc.

[0161] Continuous monitoring: The SPC statistical unit of the verification module analyzes the weight data of continuous products in real time. It focuses not only on the pass / fail status of individual products, but also on the stability of the process. The mean (X) and range (R) of the calculation process.

[0162] Identify abnormal patterns: such as 7 consecutive points deviating to one side of the target value (indicating systematic deviation); continuous rise or fall (indicating parameter drift); single point exceeding the control limit (random anomaly).

[0163] Intelligent Adjustment: When the deviation analysis unit of the adjustment module identifies a systematic deviation pattern (for example, the particle feeding at station 3 is 1% lighter than expected in 10 consecutive feedings), it will activate: Root cause analysis: Based on batch information of materials, determine whether the change is due to changes in material characteristics (such as changes in the moisture content of goji berries leading to changes in density) or equipment performance drift.

[0164] Parameter optimization: The parameter optimization unit initiates the algorithm. For example, for the pellet mechanism, a new feed hole compensation coefficient is calculated; for the vibration mechanism, the "weight-time" curve is recalibrated and the feeding time ΔT is fine-tuned; for the tilting mechanism, it is recommended to adjust the number of grippers.

[0165] Execution and Verification: The adjustment unit safely sends the new parameters to the corresponding feeding mechanism. The system monitors the weighing results for several subsequent cycles to verify the adjustment effect, forming a complete learning loop of "monitoring-analysis-adjustment-verification".

[0166] Deep collaboration among modules: Command flow: Human-machine interaction module → Main control unit / device collaboration module → Physical devices (motors, push rods, valves); Data flow: Pressure sensor 17, pressure sensor 27 and weighing sensor 30 → weighing module → verification module → decision result; Feedback flow: SPC data from the verification module → data management module → adjustment module → parameter optimization instruction → equipment collaboration module → feeding mechanism; Traceability: All lifecycle data is archived uniformly by the data management module, and production reports and quality traceability chains for any batch, time, and workstation can be generated through the human-computer interaction module.

[0167] In summary, this invention adopts a closed-loop sorting mechanism of "rotational verification and physical partitioning". The weighing unit is driven to rotate precisely between four stations by a cam divider, which converts the weight judgment (qualified / too light / too heavy) into physical position, so as to realize the online, automatic and non-destructive rejection of unqualified products and ensure the weight qualification rate of the output materials.

[0168] This invention constructs a complete data intelligence closed loop of "perception-decision-execution-optimization". The six major software modules work together to not only control in real time, but also analyze historical data by adjusting the modules, learn from it, and optimize the feeding parameters in reverse, enabling the equipment to proactively adapt to material fluctuations and upgrade from an automated machine to an intelligent production unit.

[0169] This invention enables flexible, high-precision production. It integrates three metering mechanisms—particle control, vibration, and tilting—to optimize the feeding strategy from the source, catering to different material characteristics. Through redundant weighing verification and pneumatic cleaning design, it ultimately ensures comprehensive accuracy, long-term stability, and production efficiency.
