Description

Technical Field

[0001] This application relates to the field of intelligent control technology, and in particular to a batching and mixing production line and process based on intelligent control. Background Technology

[0002] Nutrition bars, as a convenient health food, are experiencing increasing market demand. Their production materials typically include base powders, granular additives, and binders such as syrups. During the mixing stage, the pre-mixed powders and granules are finally stirred with the syrup to form a homogeneous semi-finished product with a specific texture. The efficiency and hygiene standards of this mixing process directly affect the taste, quality stability, and production cost of the final product.

[0003] Currently, the above-mentioned mixing process still heavily relies on manual operation and independent equipment. Operators first use independent mixing equipment to mix the powder and granules separately until they are evenly mixed. Then, they manually weigh the powder and granules using a scale or platform scale to determine the required weight of each batch. Subsequently, operators need to manually move the weighed powder and granules to the final mixing device and pour them into it; at the same time, another operator needs to measure and add the predetermined proportion of syrup.

[0004] However, the material transfer and delivery process relies heavily on manual labor, which severely restricts the improvement of the overall production capacity. Manual operation directly increases the time and range of material exposure to air, increasing the risk of material contamination by microorganisms, dust and other pollutants, posing a serious threat to food safety. Furthermore, manual weighing and feeding inevitably introduce errors, resulting in fluctuations in the ratio of powder, granules and syrup between different batches, which directly affects the uniformity of taste and textural stability of the final nutrition bars. Summary of the Invention

[0005] To reduce the possibility of material contamination and improve production efficiency and the accuracy of the proportions between different ingredients, this application provides a batching and mixing production line based on intelligent control.

[0006] The batching and mixing production line based on intelligent control provided in this application adopts the following technical solution: A batching and mixing production line based on intelligent control includes a frame, a first mixing subsystem for processing powder, a second mixing subsystem for processing granular materials, a mixing silo for mixing powder and granular materials, and a mixing device for final mixing of the mixed materials. The second mixing subsystem has the same structure as the first mixing subsystem and is arranged in parallel. The top of the mixing silo has two inlets, which are respectively connected to the outlets of the first mixing subsystem and the second mixing subsystem. The outlet of the mixing silo is connected to the inlet of the mixing device. A vacuum storage chamber is arranged below the outlet of the mixing device, and the outlet of the mixing device is connected to the inlet of the vacuum storage chamber. The mixed materials are temporarily stored in the vacuum storage chamber by a closed conveying method.

[0007] By adopting the above technical solution, powdered raw materials and granular raw materials enter the first and second mixing subsystems set up in parallel, respectively. In each subsystem, the materials undergo a pretreatment process of automatic feeding, dust removal, screening, vacuum conveying, precise weighing and mixing, and temporary storage. After the pretreatment is completed, the precisely proportioned powder and granular materials are independently conveyed to two independent inlets at the top of the mixing silo for preliminary dry mixing. Subsequently, the pre-mixed materials enter the stirring device for final homogenization and stirring with the syrup. After stirring, the finished material is conveyed to the vacuum storage silo through a closed pipeline under the negative pressure of the vacuum system for temporary storage, preparing for the subsequent metering and packaging process. The entire process ensures the airtightness and continuity of the material transfer process, effectively solving the problems of low efficiency and pollution risks caused by manual feeding.

[0008] Preferably, the stirring device includes a stirring chamber and a stirring shaft, the stirring shaft being rotatably disposed within the stirring chamber, and the stirring device further includes a first driving mechanism for driving the stirring shaft to rotate, a plurality of stirring rods being rotatably disposed on the peripheral sidewall of the stirring shaft, and a driving assembly for driving the stirring rods to rotate on the stirring shaft.

[0009] By adopting the above technical solution, when it is necessary to mix the materials in the mixing device, the first drive mechanism first drives the stirring shaft to rotate in the mixing chamber. The viscosity of the materials in the mixing device gradually increases as the mixing process proceeds. At this time, the drive component is triggered, and the drive component can gradually drive the stirring rod to rotate as the material viscosity increases. In the initial stage, the material viscosity is low, the deflection angle of the stirring rod is small, and the shear force is large, which helps to quickly break up dry powder clumps. In the later stage, the material viscosity is high. If the stirring rod maintains a fixed high shear force, it will squeeze and crush solid particles such as nut pieces in the material, resulting in a rough texture of the nutrition bars. Therefore, in this mixing device, when the material viscosity is high, the drive component can drive the stirring rod to rotate, thereby increasing the deflection angle of the stirring rod, reducing the shear force of the stirring rod, and thus reducing the particle breakage rate.

[0010] Preferably, the first driving mechanism includes a drive motor, a first rotating rod, a second rotating rod, and a first belt. The drive motor is mounted on the top side wall of the mixing chamber. Both the first rotating rod and the second rotating rod are vertically arranged on the top side wall of the mixing chamber, and both rotating rods are rotatably arranged on the top side wall of the mixing chamber. One end of the first rotating rod is provided with a connecting component for connecting to the drive motor, and the other end of the first rotating rod is provided with a connecting component for connecting to the second rotating rod. The two ends of the first belt are respectively sleeved on the second rotating rod and the mixing shaft, and are driven through the second rotating rod and the mixing shaft.

[0011] By adopting the above technical solution, the drive motor drives the first rotating rod through the connecting assembly, and the first rotating rod drives the second rotating rod to rotate synchronously through the connecting piece. The second rotating rod finally transmits power to the stirring shaft through the first belt. Reliable power transmission from the motor to the stirring shaft is achieved through multi-stage transmission, reducing the difficulty of rotating the stirring shaft.

[0012] Preferably, the drive assembly includes a damping plate, a threaded rod, and a threaded sleeve. A rotating rod is fixedly disposed on one side of the damping plate. The threaded rod is rotatably disposed inside the stirring shaft. One end of the rotating rod is rotatably disposed on the side wall of the stirring shaft and extends into the stirring shaft. A gear is fixedly disposed on one end of the rotating rod inside the stirring shaft. A gear is fixedly disposed on the side wall of the threaded rod. The gear and the gear mesh with each other. The threaded sleeve slides vertically within the stirring shaft and is threadedly engaged with the threaded rod; a rotating rod two is fixedly provided on one side of the stirring rod, the rotating rod two is rotatably disposed on the side wall of the stirring shaft and extends into the stirring shaft; a gear three is fixedly provided at one end of the rotating rod two located inside the stirring shaft, and a rack one is fixedly provided on the side wall of the threaded sleeve, the rack one meshing with the gear three.

[0013] By adopting the above technical solution, when the viscosity of the material in the mixing chamber gradually increases, the mixing resistance of the damping plate increases, the damping plate is subjected to a reverse force, and drives the rotating rod to rotate. The rotating rod drives the gear to rotate, the gear drives the gear to rotate, the gear drives the threaded rod to rotate, the threaded rod drives the threaded sleeve to move vertically along the axis of the mixing shaft, the threaded sleeve drives the rack to move, the rack drives the gear to rotate, and the gear drives the mixing rod to rotate through the rotating rod. This makes it easy to adjust the deflection angle of the mixing rod, so that the mixing rod can adaptively adjust its own deflection angle according to the change of material viscosity, thereby making it easy to adjust its own shear force on the material.

[0014] Preferably, the stirring device further includes a plurality of scrapers for scraping the mixture off the inner wall of the stirring chamber. The scrapers are rotatably disposed in the stirring chamber along the circumference of the stirring chamber and can move radially along the stirring chamber. The stirring device further includes a rotating mechanism for driving the scrapers to rotate and a second driving mechanism for driving the scrapers to move.

[0015] By adopting the above technical solution, when the stirring shaft drives the stirring rod to rotate and stir the material, the set rotation mechanism can simultaneously drive scraper one to rotate around the circumference of the mixing chamber, and the set second driving mechanism can drive scraper one to gradually approach the inner wall of the mixing chamber according to the increase of material viscosity. When the material viscosity is low, the distance between scraper one and the inner wall of the mixing chamber is relatively far, so that the material attached to the chamber wall can be initially cleaned; when the material viscosity increases, the second driving mechanism drives scraper one to approach the chamber wall, so that the gap between scraper one and the chamber wall is reduced, so that the material on the chamber wall can be scraped off more thoroughly; scraper one can move according to the viscosity of the material and under the action of the second driving mechanism to adjust the gap between it and the chamber wall, so as to avoid high viscosity material sticking to the wall and prevent excessive friction between scraper one and the chamber wall during the low viscosity stage.

[0016] Preferably, the rotating mechanism includes an annular rotating plate, a fourth gear, a third rotating rod, a fifth gear, and a second belt. The annular rotating plate is rotatably mounted on the top side wall of the mixing chamber, and the fourth gear is fixedly mounted on the inner wall of the annular rotating plate. The third rotating rod is vertically mounted on the top side wall of the mixing chamber, and one end of the third rotating rod is rotatably mounted on the top side wall of the mixing chamber. The fifth gear is fixedly mounted on the third rotating rod and meshes with the fourth gear. A drive wheel is fixedly mounted on the third rotating rod. The drive wheel is frustum-shaped, and its cross-sectional diameter gradually increases from bottom to top. The two ends of the second belt are respectively sleeved on the third rotating rod and the drive wheel, and are driven by the third rotating rod and the drive wheel. The rotating mechanism also includes a pushing component for pushing the second belt to move vertically.

[0017] By adopting the above technical solution, when the drive motor drives the rotating rod one to rotate, the drive wheel on the rotating rod one drives the rotating rod three to rotate through the belt two, and then drives the annular rotating plate to rotate through the gear five and gear four. The annular rotating plate drives the scraper one to revolve. The set push component can steplessly adjust the speed of the annular rotating plate by changing the position of the belt two on the conical drive wheel according to the change of material viscosity. When the material viscosity increases, the push component is triggered and can drive the belt to move upward, thereby increasing the speed of the rotating rod three, which increases the speed of the annular rotating plate and the scraper one, further improving the scraping effect and efficiency of the scraper one on the bin wall when the material is in a high viscosity state.

[0018] Preferably, the pushing assembly includes a pushing rod and a push plate. The pushing rod is vertically disposed inside the side wall of the stirring shaft. The pushing rod is located above the threaded sleeve, and the pushing rod can contact and rotatably disposed at the top end of the threaded sleeve. The top end of the pushing rod slides vertically on the top side wall of the stirring chamber. The push plate is fixedly disposed on the pushing rod, and the second belt passes through and slides on the side wall of the push plate. The pushing assembly also includes a clamping member for abutting the second belt.

[0019] By adopting the above technical solution, when the material viscosity increases, leading to an increase in stirring resistance, the threaded sleeve moves upward under the action of the drive assembly, lifting the push rod. The push rod drives the push plate and belt two to move vertically on the conical drive wheel, thereby changing the transmission ratio and increasing the revolution speed of scraper one. The set clamping part ensures that belt two is always in close contact with the side wall of the rotating rod three and the drive wheel, realizing the linkage control between the scraping speed and the material viscosity. The higher the material viscosity, the faster the scraping speed, thus more effectively overcoming the adhesion of high-viscosity materials and improving cleaning efficiency.

[0020] Preferably, the second driving mechanism includes an upper lifting plate one and an upper lifting plate two. The upper lifting plate one is fixedly mounted on the push rod, and the upper lifting plate two is located above the upper lifting plate one and slides vertically against the side wall of the annular rotating plate. The upper lifting plate one can contact and slide against the side wall of the upper lifting plate two. The side wall of the scraper one is fixedly provided with an abutment block. The abutment block has an inclined surface on the side near the upper lifting plate two, and the abutment block slides and engages with the upper lifting plate two through its inclined surface. The third driving mechanism also includes a reset component for resetting the lifting plate two and a reset member for resetting the scraper one.

[0021] By adopting the above technical solution, when the push rod moves upward, the lifting plate one lifts the lifting plate two, and the lifting plate two pushes the abutment block through the inclined surface on the abutment block. The abutment block drives the scraper one to move closer to the bin wall, thereby reducing the difficulty of the scraper one moving closer to the bin wall. When the material in the bin is unloaded, the push rod resets. The reset component and reset assembly can reset the scraper one and the lifting plate two to their initial positions.

[0022] Preferably, the inner wall of the mixing chamber is vertically slidable with a second scraper for scraping off the mixture, and the mixing device further includes a fourth driving mechanism for driving the second scraper to move vertically.

[0023] By adopting the above technical solution, when the material in the mixing chamber is mixed and needs to be unloaded, the fourth driving mechanism can drive the scraper two to move downward during the unloading process. The scraper two can scrape off the material on the chamber wall, thereby reducing the amount of mixed material remaining in the mixing chamber and making the material in the mixing chamber as clean as possible.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. Powdered and granular raw materials are respectively fed into a first and second mixing subsystem set up in parallel. In each subsystem, the materials undergo a pretreatment process of automatic feeding, dust removal, screening, vacuum conveying, precise weighing and mixing, and temporary storage. After pretreatment, the precisely proportioned powder and granules are independently conveyed to two independent inlets at the top of the mixing silo for preliminary dry mixing. Subsequently, the pre-mixed materials enter a stirring device for final homogenization with syrup. After stirring, the finished material is conveyed through a closed pipeline to a vacuum storage silo under the negative pressure of the vacuum system for temporary storage, preparing for subsequent metering and packaging processes. The entire process ensures the airtightness and continuity of the material transfer process, effectively solving the inefficiency and pollution risks caused by manual feeding. 2. When it is necessary to mix the materials in the mixing device, the first drive mechanism first drives the stirring shaft to rotate in the mixing chamber. As the mixing process progresses, the viscosity of the materials in the mixing device gradually increases. At this time, the drive component is triggered, and the drive component can gradually drive the stirring rod to rotate as the material viscosity increases. In the initial stage, the material viscosity is low, the deflection angle of the stirring rod is small, and the shear force is large, which helps to quickly break up dry powder clumps. In the later stage, the material viscosity is high. If the stirring rod maintains a fixed high shear force, it will squeeze and break solid particles such as nut pieces in the material, resulting in a rough texture of the nutrition bars. Therefore, in this mixing device, when the material viscosity is high, the drive component can drive the stirring rod to rotate, thereby increasing the deflection angle of the stirring rod, reducing the shear force of the stirring rod, and thus reducing the particle breakage rate. 3. As the viscosity of the material in the mixing chamber gradually increases, the mixing resistance on the damping plate increases, and the damping plate experiences a reverse force, driving the rotating rod to rotate. The rotating rod drives the gear to rotate, which in turn drives the gear to rotate. The gear to rotate drives the threaded rod to rotate, which in turn drives the threaded sleeve to move vertically along the axis of the mixing shaft. The threaded sleeve drives the rack to move, which in turn drives the gear to rotate. The gear to rotate drives the mixing rod through the rotating rod, thus facilitating the adjustment of the deflection angle of the mixing rod. This allows the mixing rod to adaptively adjust its deflection angle according to changes in the material viscosity, thereby facilitating the adjustment of its shear force on the material.

[0025] A batching and mixing production process based on intelligent control includes the following steps: S1. Automatic pre-processing and conveying of raw materials: Operators feed powder and granular materials into the first and second integrated dust-removing vibrating screens, respectively. The equipment completes the screening through the vibrating screen and starts the dust removal system to collect dust. The processed materials are conveyed by the first and second vacuum feeders through closed pipelines to the corresponding pull-out mixers. After homogenization and mixing, the materials are temporarily stored in the first and second storage bins. Each storage bin is equipped with a level sensor to monitor the material inventory in real time and feed it back to the central controller to realize automatic scheduling and inventory management. S2. Precise ingredient dispensing and premixing: The central controller controls the dispensing screws of the first and second weighing hoppers according to the formula parameters, and puts the precisely weighed powder and granular materials into the mixing hopper; the mixing hopper starts the low-speed stirring mechanism to complete the dry premixing and avoid agglomeration and stratification. S3. Syrup addition and stirring: The syrup supply device pumps the syrup into the stirring device in proportion, and the syrup is wet-mixed together with the premixed material; The drive motor of the stirring device drives the stirring shaft to rotate through rotating rod one, rotating rod two and belt one to realize the basic mixing function. S4. Adaptive Mixing and Intelligent Cleaning: During the mixing process, the damping plate of the drive component senses the material resistance in real time. Through gear one and gear two, it drives the threaded rod to rotate, driving the threaded sleeve to move. Then, through the meshing of rack one and gear three, it adjusts the rotation speed of the mixing rod to enhance the shearing force. Scraper one revolves along the inner wall of the mixing chamber under the drive of the rotating mechanism. Its rotation speed is infinitely adjustable through the cooperation of the drive wheel and belt two. The push component dynamically adjusts the radial position of scraper one according to the material viscosity. In conjunction with the vertical movement of scraper two, it thoroughly removes the material adhering to the inner wall. The cleaning data is uploaded to the central controller in real time. S5. Vacuum Conveying and Quantitative Packaging: After mixing, the material is conveyed to the vacuum storage chamber via a vacuum system, and then quantitatively packaged through a star-shaped unloading valve; the central controller records the entire production process data, supporting quality traceability and process optimization.

Detailed Implementation

[0029] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0030] This application discloses an intelligent control-based ingredient mixing production line, such as... Figure 1 and Figure 2 As shown, it includes a frame 1, a first mixing subsystem 2 for processing powder materials, a second mixing subsystem 3 for processing granular materials, a mixing hopper 4 for mixing powder materials and granular materials, and a mixing device 5 for final mixing of the mixed materials.

[0031] like Figure 1 and Figure 2As shown, the first mixing subsystem 2 includes a first discharge dust removal vibrating screen integrated machine 6, a first vacuum feeder 7, a first pull-out mixer 8, a first storage silo 9, and a first weighing silo 10 arranged sequentially along the material conveying direction. The first discharge dust removal vibrating screen integrated machine 6 is used to perform preliminary screening and dust removal on the input powder. The first vacuum feeder 7 conveys the screened and dust-removed powder to the first pull-out mixer 8 in a sealed manner through negative pressure pneumatic conveying. The first pull-out mixer 8 is used to fully mix the powder to ensure the uniform distribution of each component of the powder. The first storage silo 9 is located below the discharge port of the first pull-out mixer 8 and is used to receive and temporarily store the mixed powder. The inlet of the first weighing silo 10 is connected to the outlet of the first storage silo 9 through a first batching screw, and the powder is accurately weighed by a precision weighing sensor to ensure the accuracy of the formula ratio.

[0032] like Figure 1 and Figure 2 As shown, the second mixing subsystem 3 has the same structure as the first mixing subsystem 2 and is arranged in parallel. It includes a second integrated dust-removing vibrating screen, a second vacuum feeder, a second pull-out mixer, a second storage silo, and a second weighing silo, arranged sequentially. The second mixing subsystem 3 is specifically designed for processing granular materials, and its process flow is the same as that of the first mixing subsystem 2, ensuring that the granular materials undergo screening, dust removal, mixing, storage, and accurate weighing.

[0033] like Figure 1 and Figure 2 As shown, the mixing silo 4 is used to initially mix the powder and granules weighed according to the formula. It has two inlets on the top, which are connected to the outlets of the first weighing silo 10 and the second weighing silo, respectively. The mixing silo 4 can uniformly mix the powder and granules. The outlet of the mixing silo 4 is connected to the inlet of the stirring device 5, and the initially mixed material is sent to the stirring device 5 for final mixing with the syrup.

[0034] like Figure 1 and Figure 2 As shown, the stirring device 5 performs final stirring on the mixed materials to ensure that the materials reach the optimal mixing state; a vacuum storage chamber is set below the discharge port of the stirring device 5, and the discharge port of the stirring device 5 is connected to the inlet of the vacuum storage chamber. The mixed materials are sent into the vacuum storage chamber for temporary storage through a closed conveying method.

[0035] like Figure 1 and Figure 2 As shown, the outlet of the vacuum storage chamber is connected to the vacuum feeder and the vacuum buffer chamber in sequence through a vacuum conveying pipeline, forming a complete material conveying system; the outlet of the vacuum buffer chamber is equipped with a star-shaped unloading valve, which achieves quantitative packaging of the final product by precisely controlling the unloading speed and time.

[0036] like Figure 1 and Figure 2 As shown, the entire process ensures the airtightness and continuity of material transfer, effectively solving the problems of low efficiency and pollution risk caused by manual feeding.

[0037] like Figure 3 and Figure 4 As shown, the stirring device 5 includes a stirring chamber 51 and a stirring shaft 52. The stirring shaft 52 is vertically arranged at the central axis of the stirring chamber 51. A bracket is fixedly connected to the inner wall of the stirring chamber 51. The bottom end of the stirring shaft 52 is rotatably connected to the bracket through a bearing. The stirring device 5 also includes a first driving mechanism 53 for driving the stirring shaft 52 to rotate. A plurality of stirring rods 54 are rotatably arranged on the peripheral side wall of the stirring shaft 52. A driving assembly 55 for driving the stirring rods 54 to rotate is provided on the stirring shaft 52.

[0038] like Figure 3 and Figure 4 As shown, when the material in the mixing device 5 needs to be mixed, the first driving mechanism 53 drives the mixing shaft 52 to rotate in the mixing chamber 51. The viscosity of the material in the mixing device 5 gradually increases as the mixing process progresses. At this time, the driving component 55 is triggered, and the driving component 55 can gradually drive the mixing rod 54 to rotate as the viscosity of the material increases. In the initial stage, the viscosity of the material is low, and the deflection angle of the mixing rod 54 is small, resulting in a large shear force, which helps to quickly break up dry powder clumps. In the later stage, the viscosity of the material is high. If the mixing rod 54 maintains a fixed high shear force, it will squeeze and crush solid particles such as nut pieces in the material, resulting in a rough texture of the nutrition bar. Therefore, in the mixing device 5, when the viscosity of the material is high, the driving component 55 can drive the mixing rod 54 to rotate, thereby increasing the deflection angle of the mixing rod 54, reducing the shear force of the mixing rod 54, and thus reducing the particle breakage rate.

[0039] like Figure 4 and Figure 5 As shown, the first drive mechanism 53 includes a drive motor 531, a first rotating rod 532, a second rotating rod 533, and a first belt 534. The drive motor 531 is mounted on the top side wall of the mixing chamber 51, and the shaft of the drive motor 531 is vertically downward. The first rotating rod 532 and the second rotating rod 533 are both vertically mounted on the top side wall of the mixing chamber 51. The first rotating rod 532 is located above the second rotating rod 533, and the two are coaxial. A support plate 535 is fixedly connected to the top inner wall of the mixing chamber 51. The bottom end of the second rotating rod 533 is rotatably connected to the support plate 535 through a bearing, and the top end of the first rotating rod 532 is rotatably connected to the top inner wall of the mixing chamber 51 through a bearing.

[0040] like Figure 4 , Figure 5 , Figure 6 as well as Figure 7As shown, the top end of the rotating rod 532 is provided with a connecting assembly 536 for connecting to the drive motor 531. The connecting assembly 536 includes a connecting rod 5361, which is vertically arranged and coaxial with the rotating rod 532. The bottom end of the connecting rod 5361 passes through and is rotatably connected to the top side wall of the mixing chamber 51, and passes through the top side wall of the rotating rod 532. The top end of the connecting rod 5361 is fixedly connected to the rotating shaft of the drive motor 531 by a coupling. Multiple limiting blocks 5362 slide radially inside the side wall of the connecting rod 5361. The multiple limiting blocks 5362 are arranged circumferentially along the connecting rod 5361. The inner wall of the rotating rod 532 is provided with a limiting groove for the limiting blocks 5362 to be inserted.

[0041] like Figure 4 and Figure 5 As shown, the bottom end of the rotating rod 532 is provided with a connecting piece for connecting the rotating rod 533; the connecting piece is an overrunning clutch, and the two ends of the belt 534 are respectively sleeved on the rotating rod 533 and the stirring shaft 52, and are driven through the rotating rod 533 and the stirring shaft 52.

[0042] like Figure 4 , Figure 5 , Figure 6 as well as Figure 7 As shown, during the mixing process in the mixing chamber 51, the limiting block 5362 is inserted into the limiting groove 532 of the rotating rod 532, connecting the connecting rod 5361 and the rotating rod 532. At this time, the drive motor 531 drives the rotating rod 532 to rotate through the connecting rod 5361. The rotating rod 532 drives the rotating rod 533 to rotate synchronously through the overrunning clutch. The rotating rod 533 finally transmits power to the mixing shaft 52 through the belt 534. Reliable power transmission from the motor to the mixing shaft 52 is achieved through multi-stage transmission, reducing the difficulty of rotating the mixing shaft 52.

[0043] like Figure 4 , Figure 6 as well as Figure 8As shown, the drive assembly 55 includes a damping plate 551, a threaded rod 552, and a threaded sleeve 553. The length and area of ​​the damping plate 551 are greater than the length and area of ​​the stirring rod 54. Multiple damping plates 551 are provided and arranged along the circumference of the stirring shaft 52. A rotating rod 554 is fixedly connected to the side of the damping plate 551 near the stirring shaft 52. The rotating rod 554 is arranged horizontally along the radial direction of the stirring shaft 52. The threaded rod 552 is vertically arranged on the inner wall of the stirring shaft 52 and is coaxial with the stirring shaft 52. The threaded rod 552 is rotatably connected to the inner wall of the stirring shaft 52 through a bearing. One end of the rotating rod 554 passes through and is rotatably connected to the side wall of the stirring shaft 52 and extends into the stirring shaft 52. A gear 555 is sleeved and fixed at the end of the rotating rod 554 located inside the stirring shaft 52. A gear 556 is sleeved and fixed on the side wall of the threaded rod 552. The gear 555 and the gear 556 mesh with each other.

[0044] like Figure 4 , Figure 6 as well as Figure 8 As shown, the threaded sleeve 553 is vertically installed inside the side wall of the stirring shaft 52 and is coaxial with the stirring shaft 52; the threaded sleeve 553 slides vertically on the inner wall of the stirring shaft 52, and is fitted and threadedly connected to the threaded rod 552; a rotating rod 557 is fixedly connected to the side of the stirring rod 54 near the stirring shaft 52, the rotating rod 557 is horizontally arranged along the radial direction of the stirring shaft 52, one end of the rotating rod 557 is rotatably connected to the side wall of the stirring shaft 52 and extends into the stirring shaft 52; a gear 558 is fitted and fixed to the end of the rotating rod 557 located inside the stirring shaft 52, and the threaded sleeve... A rack 559 is fixedly connected to the side wall of 553. The rack 559 is vertically arranged and meshes with a gear 558. A torsion spring 560 is sleeved on the rotating rod 554. The torsion spring 560 is located inside the stirring shaft 52. The two ends of the torsion spring 560 are fixedly set on the inner walls of the rotating rod 554 and the stirring shaft 52, respectively, for resetting the damping plate 551. Stops 561 are fixedly connected to the outer wall of the stirring shaft 52 at the upper and lower sides of the damping plate 551 to limit the deflection angle of the damping plate 551 and reduce the possibility of the damping plate 551 flipping at a large angle.

[0045] like Figure 4 , Figure 6 as well as Figure 8As shown, when the viscosity of the material in the mixing chamber 51 gradually increases, the mixing resistance of the damping plate 551 increases, and the damping plate 551 is subjected to a reverse force, which drives the rotating rod 554 to rotate. The rotating rod 554 drives the gear 555 to rotate, the gear 555 drives the gear 556 to rotate, the gear 556 drives the threaded rod 552 to rotate, the threaded rod 552 drives the threaded sleeve 553 to move vertically along the axial direction of the mixing shaft 52, the threaded sleeve 553 drives the rack 559 to move, the rack 559 drives the gear 558 to rotate, and the gear 558 drives the mixing rod 54 to rotate through the rotating rod 557. This allows for easy adjustment of the deflection angle of the mixing rod 54, enabling the mixing rod 54 to adaptively adjust its deflection angle according to the change in material viscosity, thereby facilitating the adjustment of its shear force on the material.

[0046] like Figure 4 , Figure 6 as well as Figure 9 As shown, the mixing device 5 also includes a plurality of scrapers 56 for scraping the mixture off the inner wall of the mixing chamber 51. The scrapers 56 are rotatably disposed in the mixing chamber 51 along the circumference of the mixing chamber 51, and the scrapers 56 can move radially along the mixing chamber 51. The mixing device 5 also includes a rotating mechanism 57 for driving the scrapers 56 to rotate and a second driving mechanism 58 for driving the scrapers 56 to move.

[0047] like Figure 4 , Figure 6 as well as Figure 9 As shown, when the stirring shaft 52 drives the stirring rod 54 to rotate and stir the material, the rotating mechanism 57 can simultaneously drive the scraper 56 to rotate circumferentially along the mixing chamber 51. The second driving mechanism 58 can drive the scraper 56 to gradually approach the inner wall of the mixing chamber 51 according to the increase in material viscosity. When the material viscosity is low, the distance between the scraper 56 and the inner wall of the mixing chamber 51 is relatively large, thus initially cleaning the material adhering to the chamber wall. When the material viscosity increases, the second driving mechanism 58 drives the scraper 56 closer to the chamber wall, reducing the gap between the scraper 56 and the chamber wall, thus scraping the material off the chamber wall more thoroughly. The scraper 56 can move according to the material viscosity and under the action of the second driving mechanism 58 to adjust the gap between it and the chamber wall, preventing highly viscous materials from sticking to the wall and preventing excessive friction between the scraper 56 and the chamber wall during the low viscosity stage.

[0048] like Figure 4 , Figure 5 , Figure 6 as well as Figure 9As shown, the rotating mechanism 57 includes an annular rotating plate 571, gear four 572, rotating rod three 573, gear five 574, and belt two 575. The annular rotating plate 571 is coaxial with the stirring shaft 52 and is rotatably connected to the top side wall of the stirring chamber 51 through bearings. Gear four 572 is a ring gear and is fixedly connected to the inner wall of the annular rotating plate 571. Rotating rod three 573 is vertically arranged on the top side wall of the stirring chamber 51, and the top end of rotating rod three 573 is rotatably connected to the top side wall of the stirring chamber 51 through bearings. Gear 574 is sleeved and fixed on rotating rod 3 573, and gear 574 meshes with gear 4 572; a drive wheel 576 is sleeved and fixed on rotating rod 1 532. The drive wheel 576 is frustoconical, and the cross-sectional diameter of the drive wheel 576 gradually increases from bottom to top; the two ends of belt 2 575 are respectively sleeved on rotating rod 3 573 and drive wheel 576, and are driven by rotating rod 3 573 and drive wheel 576; the rotating mechanism 57 also includes a push assembly 577 for pushing belt 2 575 to move vertically.

[0049] like Figure 4 , Figure 5 , Figure 6 as well as Figure 9 As shown, when the drive motor 531 drives the rotating rod 532 to rotate, the drive wheel 576 on the rotating rod 532 drives the rotating rod 573 to rotate via the belt 575, and then drives the annular rotating plate 571 to rotate via the gear 574 and the gear 4 572. The annular rotating plate 571 drives the scraper 56 to revolve. The push component 577 can steplessly adjust the speed of the annular rotating plate 571 by changing the position of the belt 575 on the conical drive wheel 576 according to the change of material viscosity. When the material viscosity increases, the push component 577 is triggered and can drive the belt to move upward, thereby increasing the speed of the rotating rod 573. This increases the speed of the annular rotating plate 571 and the scraper 56, further improving the scraping effect and efficiency of the scraper 56 on the silo wall when the material is in a high viscosity state.

[0050] like Figure 4 , Figure 5 , Figure 6 as well as Figure 9As shown, the pushing assembly 577 includes a pushing rod 5771 and a push plate 5772. The pushing rod 5771 is vertically disposed inside the top side wall of the stirring shaft 52, and is coaxial with the stirring shaft 52. The pushing rod 5771 is located above the threaded sleeve 553. The bottom end of the pushing rod 5771 is rotatably connected to the top end of the threaded sleeve 553 via a bearing. The pushing rod 5771 slides vertically inside the top side wall of the stirring shaft 52, and the top end of the pushing rod 5771 can extend to the outside of the top end of the stirring shaft 52. The push plate 5772 is fixed. The push assembly 577 is fixedly connected to the top of the push rod 5771. The second belt 575 passes through and slides horizontally on one side wall of the push plate 5772. The push assembly 577 also includes a clamping member for pressing against the second belt 575. The clamping member is a clamping spring. A roller 1 slides inside the side wall of the push plate 5772. The peripheral side wall of the roller 1 contacts and rolls against the outer side wall of the second belt 575. The two ends of the clamping spring abut against the roller 1 and the side wall of the push plate 5772 respectively, so that the roller 1 can always be pressed against and rolled against the outer side wall of the second belt 575.

[0051] like Figure 4 , Figure 5 , Figure 6 as well as Figure 9 As shown, when the material viscosity increases, leading to increased stirring resistance, the threaded sleeve 553 moves upward under the action of the drive assembly 55, lifting the push rod 5771. The push rod 5771 drives the push plate 5772 and the second belt 575 to move vertically on the conical drive wheel 576, thereby changing the transmission ratio and increasing the revolution speed of the scraper 56. The set clamping spring ensures that the second belt 575 is always in close contact with the side wall of the rotating rod 573 and the drive wheel 576, realizing the linkage control between the scraping speed and the material viscosity. The higher the material viscosity, the faster the scraping speed, thus more effectively overcoming the adhesion of high-viscosity materials and improving cleaning efficiency.

[0052] like Figure 4 , Figure 5 , Figure 6 as well as Figure 9As shown, the second drive mechanism 58 includes an upper lifting plate 581 and an upper lifting plate 582. The upper lifting plate 581 is fixedly connected to the side wall of the push plate 5772. The upper lifting plate 582 is annular and coaxial with the annular rotating plate 571. The upper lifting plate 582 is located above the upper lifting plate 581 and slides vertically on the bottom side wall of the annular rotating plate 571. The top side wall of the upper lifting plate 581 is fitted with and rolled with multiple balls, which can contact and roll on the upper lifting plate. The bottom side wall of the second lifting plate 582; the scraper 56 is fixedly connected to the side wall of the second lifting plate 582 with an abutment block 583. The side of the abutment block 583 with an inclined surface is provided on the side of the second lifting plate 582. The roller shaft 2 is rotatably connected to the inclined surface of the abutment block 583. The roller shaft 2 is set along the inclined direction of the abutment block 583. The peripheral side wall of the second lifting plate 582 can contact the side wall of the roller shaft 2 and slide along the axial direction of the roller shaft 2. The roller shaft 2 can be rolled and connected to the peripheral side wall of the second lifting plate 582.

[0053] like Figure 4 , Figure 5 , Figure 6 as well as Figure 9 As shown, the third drive mechanism 60 also includes a reset assembly 584 for resetting the second lifting plate and a reset component for resetting the first scraper 56. The reset assembly 584 includes a first spring 5841 and a guide rod 5842. The first spring 5841 and the guide rod 5842 are both vertically arranged between the second lifting plate and the annular rotating plate 571. The first spring 5841 is sleeved on the guide rod 5842. The bottom end of the guide rod 5842 is fixedly connected to the top side wall of the second lifting plate, and the top end of the guide rod 5842 is vertically slidably connected to the bottom side wall of the annular rotating plate 571. The two ends of the first spring 5841 respectively abut against the inner walls of the annular rotating plate 571 and the second lifting plate. The reset component is a second spring 585. The second spring 585 is horizontally arranged along the radial direction of the annular rotating plate 571 inside the side wall of the annular rotating plate 571, and the two ends of the second spring 585 are fixedly connected to the first scraper 56 and the inner wall of the annular rotating plate 571 respectively.

[0054] like Figure 4 , Figure 5 , Figure 6 as well as Figure 9 As shown, when the push rod 5771 moves upward, it lifts the second lifting plate 582 through the first lifting plate 581, compressing the first spring 5841. The second lifting plate 582 pushes the abutment block 583 through the inclined surface on the abutment block 583, which drives the scraper 56 to move closer to the bin wall. The second spring 585 is compressed, thereby reducing the difficulty of the scraper 56 moving closer to the bin wall. When the material in the bin is unloaded, the push rod 5771 resets, and the second spring 585 and the first spring 5841 can push the scraper 56 and the second lifting plate to reset to the initial position.

[0055] like Figure 4, Figure 5 , Figure 6 as well as Figure 7 As shown, a second scraper 59 for scraping off the mixture is vertically slidable on the inner wall of the mixing chamber 51. The second scraper 59 is annular and coaxial with the mixing shaft 52. The mixing device 5 also includes a third driving mechanism 60 for driving the second scraper 59 to move vertically. The driving mechanism includes a lead screw 601, a first driving ring plate 602, and a third belt 620. The lead screw 601 is vertically arranged inside the peripheral wall of the mixing chamber 51 and is rotatably connected to the peripheral wall of the mixing chamber 51 through bearings. The first driving ring plate 602 slides vertically. The drive ring plate 602 is moved into the side wall of the mixing chamber 51, and the lead screw 601 is threaded through and connected to the side wall of the drive ring plate 602. The inner circumferential wall of the drive ring plate 602 is rotatably connected to the drive ring plate 603 via bearings. Multiple permanent magnets are installed on the drive ring plate 603 and the scraper 59. The multiple permanent magnets on the drive ring plate 603 and the multiple permanent magnets on the scraper 59 are arranged one-to-one and attract each other. The drive ring plate 602, the drive ring plate 603 and the scraper 59 always maintain the same height.

[0056] like Figure 4 , Figure 5 , Figure 6 as well as Figure 7 As shown, a rotating rod 604 and a rotating rod 605 are rotatably connected to the top outer wall of the mixing chamber 51 via bearings. The two ends of the belt 620 are respectively sleeved on the rotating rod 604 and the rotating rod 605, and are driven through the rotating rod 604 and the rotating rod 605. The top end of the lead screw 601 is fixedly connected to the rotating rod 604, and the lead screw 601 and the rotating rod 604 are coaxial. The connecting rod 5361 is coaxial with the rotating rod 605, and the connecting rod 5361 is vertically inserted through the side wall of the rotating rod 605. Multiple limiting blocks 606 are slidably connected to the circumferential side wall of the connecting rod 5361 along its radial direction. The inner wall of the rotating rod 605 is provided with a limiting groove for the limiting blocks 606 to be inserted.

[0057] like Figure 4 , Figure 5 , Figure 6 as well as Figure 7As shown, a drive rod 607 slides vertically within the connecting rod 5361. Multiple guide blocks 608 are fixedly connected to the circumferential sidewall of the drive rod 607. A guide groove for the guide blocks 608 to slide is formed vertically on the inner wall of the connecting rod 5361. A connecting rod 609 is provided between the first limiting block 5362 and the drive rod 607, with both ends of the connecting rod 609 hinged to the drive rod 607 and the limiting block 606, respectively. A connecting rod 610 is provided between the second limiting block 606 and the drive rod 607, with both ends of the connecting rod 610 hinged to the second limiting block 606 and the drive rod 607, respectively. The first limiting block 5362 and the second limiting block 606 are interleaved within their corresponding limiting grooves.

[0058] like Figure 4 , Figure 5 , Figure 6 as well as Figure 7 As shown, the third drive mechanism 60 also includes a controller, an electromagnet 611, and a magnetic block 612. The control terminal of the controller is electrically connected to the signal input terminal of the electromagnet 611 to control the opening and closing of the electromagnet 611 switch. The electromagnet 611 is installed inside the connecting rod 5361 and located above the drive rod 607. The magnetic block 612 is installed at the top of the drive rod 607 and can be attracted to the electromagnet 611. A spring 613 is sleeved on the drive rod 607. The upper and lower ends of the spring 613 are respectively fixed to the side wall of the drive rod 607 and the inner wall of the connecting rod 5361.

[0059] like Figure 4 , Figure 5 , Figure 6 as well as Figure 7As shown, when the material in the mixing chamber 51 is finished being mixed and needs to be unloaded, the controller controls the electromagnet 611 to be energized. The electromagnet 611 attracts the magnetic block 612, causing the drive rod 607 to move upward. The spring 613 is stretched, and the drive rod 607 drives the connecting rod 609 to rotate, causing the limiting block 5362 to move away from the rotating rod 532. At the same time, the drive rod 607 drives the connecting rod 610 to rotate, causing the limiting block 606 to move closer to the rotating rod 605 and finally insert into the limiting groove 2 in the rotating rod 605. At this time, the drive motor 531 drives the rotating rod 605 to rotate. The rotating rod 605 drives the rotating rod 604 and the lead screw 601 to rotate via the belt 3. The lead screw 601 drives the drive ring plate 602 and the drive ring plate. The second ring plate 603 moves downward, driving the second ring plate 603 through the permanent magnet, and simultaneously driving the second scraper 59 to move downward. The second scraper 59 can scrape off the material on the bin wall, thereby reducing the amount of mixture remaining in the mixing bin 51, so that the material in the mixing bin 51 is unloaded as cleanly as possible. After the lead screw 601 drives the second scraper 59 to rise to the initial position, the controller controls the electromagnet 611 to be de-energized, and the elastic force of the third spring 613 pulls the drive rod 607 downward, so that the second limit block 606 moves away from the fifth rotating rod 605, so that the first limit block 5362 moves closer to the first rotating rod 532, and finally inserts into the first limit groove on the first rotating rod 532. After that, the drive motor 531 can drive the mixing rod 54 to rotate again, so that the whole process can be repeated.

[0060] The implementation principle of this application embodiment is as follows: powdered raw materials and granular raw materials are respectively fed into the first mixing subsystem 2 and the second mixing subsystem 3, which are set in parallel. In each subsystem, the materials undergo a pretreatment process of automatic feeding, dust removal, screening, vacuum conveying, weighing and precise mixing, and temporary storage. After the pretreatment is completed, the precisely proportioned powder and granular materials are independently conveyed to two independent feed ports at the top of the mixing silo 4 for preliminary dry mixing. Subsequently, the pre-mixed materials enter the stirring device 5 for final homogenization and stirring with the syrup. After stirring is completed, the finished material is conveyed to the vacuum storage silo through a closed pipeline under the negative pressure of the vacuum system for temporary storage, in preparation for the subsequent metering and packaging process. The whole process ensures the airtightness and continuity of the material transfer process, effectively solving the problems of low efficiency and pollution risk caused by manual feeding.

[0061] A batching and mixing production process based on intelligent control includes the following steps: S1. Automatic Raw Material Pre-processing and Conveying: Operators feed powder and granular materials into the first and second integrated dust-removing vibrating screens, respectively. The equipment completes the screening through the vibrating screens and activates the dust removal system to collect dust. The processed materials are conveyed by a vacuum feeder through a closed pipeline to the corresponding pull-out mixer. After homogenization and mixing, the materials are temporarily stored in storage silos. Each storage silo is equipped with a level sensor to monitor the material inventory in real time and feed it back to the central controller, realizing automatic scheduling and inventory management.

[0062] S2. Precise Batching and Premixing: The central controller controls the batching screw of the weighing hopper according to the formula parameters, and puts the precisely weighed powder and granular materials into the mixing hopper 4. The mixing hopper 4 starts the low-speed stirring mechanism to complete the dry premixing and avoid agglomeration and stratification.

[0063] S3. Syrup Addition and Stirring: The syrup supply device pumps the syrup into the stirring device 5 according to the ratio, and performs wet stirring together with the premixed material. The drive motor 531 of the stirring device 5 drives the stirring shaft 52 to rotate through the transmission system, realizing the basic mixing function.

[0064] S4. Adaptive Mixing and Intelligent Cleaning: During mixing, the damping plate 551 of the drive component 55 senses the material resistance in real time. Through gear transmission, it drives the threaded rod 552 to rotate, which in turn drives the threaded sleeve 553 to shift. This, in turn, adjusts the rotation speed of the mixing rod 54 through the meshing of the rack and gear, enhancing the shearing force. Driven by the rotating mechanism 57, the scraper revolves along the inner wall of the mixing chamber 51. Its rotation speed is infinitely adjustable through the interaction of the drive wheel 576 and the belt. The push component 577 dynamically adjusts the radial position of the scraper according to the material viscosity. Combined with the vertically moving scraper, this thoroughly removes material adhering to the inner wall, and the cleaning data is uploaded to the central controller in real time.

[0065] S5. Vacuum Conveying and Quantitative Packaging: After mixing, the material is conveyed to a vacuum storage chamber via a vacuum system, and then quantitatively packaged through a star-shaped discharge valve. The central controller records production data throughout the entire process, supporting quality traceability and process optimization.

[0066] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
