Description

Technical Field

[0001] This invention relates to the field of cosmetic production technology, and in particular to a natural production method and intelligent integrated system for powder unit cosmetic pipelines. Background Technology

[0002] Powder-based cosmetics (such as loose powder, pressed powder, and powder base) are widely used in the cosmetics industry. The production process usually involves multiple stages such as raw material metering, mixing, conveying, temporary storage, and subsequent molding or filling.

[0003] The current production methods for powder-based cosmetics are mostly based on traditional open or semi-closed production processes. Materials are transferred and processed between multiple workstations by manual or mechanical means. This type of production mode has gradually revealed many shortcomings in the long-term application process.

[0004] In existing technologies, powder raw materials and semi-finished products are mostly prepared and transported in open containers, mixing tanks, or transfer containers. The production environment is highly dependent on air cleanliness and personnel operating procedures. During the flow of materials, they are easily affected by factors such as airborne suspended particles, microorganisms, and operator contact, thus posing a risk of contamination. Especially for high-quality or high-safety-level cosmetic products, contamination problems can easily lead to fluctuations in product quality, excessive microbial levels, or even product failure, making it difficult to consistently and stably meet increasingly stringent industry regulations and market requirements.

[0005] Meanwhile, traditional powder-based cosmetic production processes typically rely heavily on manual labor, including material handling, process coordination, equipment start-up and shutdown, and process monitoring. This not only increases labor costs but also inevitably introduces human error, affecting production consistency and product stability. Furthermore, the repeated transfer and temporary storage of materials between multiple processes lengthens production cycles and increases material losses, further driving up overall production costs and hindering the improvement of production efficiency.

[0006] From an energy and environmental perspective, existing production methods generally rely on motors, conveying equipment, and multi-stage power systems to complete material transfer, resulting in significant energy consumption. Furthermore, the production process easily generates dust, residues, and cleaning waste, placing considerable pressure on the environment. In the current context of advocating green manufacturing and low-carbon production, the traditional powder-based cosmetic production model can no longer meet the new requirements of industry development in terms of energy conservation, emission reduction, and environmental friendliness.

[0007] In summary, the existing technology has at least the following technical problems:

[0008] The existing powder unit cosmetic production process is highly open and susceptible to contamination, resulting in technical problems such as unstable product quality and safety. Summary of the Invention

[0009] The purpose of this invention is to provide a natural production method and intelligent integrated system for powder unit cosmetic pipelines, in order to solve the technical problems of the existing powder unit cosmetic production process being highly open and susceptible to contamination, resulting in unstable product quality and safety.

[0010] The preferred technical solutions among the many technical solutions provided by this invention can produce a variety of technical effects, which are described in detail below.

[0011] To address the aforementioned technical problems, the present invention provides the following technical solution:

[0012] This invention provides a natural production method for powder unit cosmetic pipelines, applicable to the formulation and filling production of powder unit cosmetics, including: S1, sealed feeding: weighed powder raw materials are fed into a dust-free feeding station and introduced into a mixing device through a sealed feeding port, and the powder raw materials are fed in sequence according to the preset product formula process feeding order.

[0013] S2. Closed mixing: The powder raw materials are mixed in the mixing equipment for 15 minutes to obtain a mixed material.

[0014] S3. Natural Power Pipeline Transfer: Using gravity and / or air pressure difference as the conveying driving force, the mixed material is transferred to the silo in the sealed pipeline and the filling and sealing are completed;

[0015] S4. Sealed feeding and filling: The hopper is transferred to the feeding station, and the two ends of the separately set sealing connection docking cavity are respectively sealed and connected to the feeding port of the feeding station and the discharge end of the hopper, and the mixed material in the hopper is fed into the bag-type automatic packaging machine through the feeding port to complete the filling.

[0016] Throughout the S1 to S4 processes, materials flow within a closed pipeline / sealed container path to reduce the risk of external contamination and improve the stability of product quality and safety.

[0017] In one embodiment, the mixing device is a single-shaft paddle mixer.

[0018] In one embodiment, in S3 and / or S4, an airtightness self-test is performed before and / or after the sealing connection between the hopper, the docking cavity, and the discharge port is completed; the airtightness self-test includes: pressurizing or evacuating the docking cavity and / or the sealed detection cavity formed by the discharge end of the hopper, the docking cavity, and the discharge port, and detecting the pressure retention rate; when the pressure retention rate does not meet a preset threshold, an interlock signal is output and material feeding to the bag-feeding automatic packaging machine is prohibited.

[0019] In one embodiment, the sealed pipeline is subjected to segmented differential pressure control: the sealed pipeline is divided into at least two conveying sections, and segmented valve groups and differential pressure monitoring points are set in each conveying section; each conveying section is controlled to open and close sequentially within a preset differential pressure window, so as to achieve stable and controllable natural power conveying without relying on continuous motor-driven conveying.

[0020] In one embodiment, a cross-station collaborative closed-loop control is established, including: before feeding materials, the upstream station sends a material preparation message to the station where the mixing equipment is located and completes the release; before unloading materials, the downstream station sends a material request message to the station where the silo is located and completes the release; through a controller installed between multiple stations, the controller releases and interlocks the mixing performed by the mixing equipment, the transfer performed by the sealed pipeline, the docking self-inspection performed by the silo, the docking cavity, and the unloading port, and the unloading action performed by the unloading station based on the material preparation message and the material request message, and generates batch traceability records.

[0021] A powder unit cosmetic intelligent integrated system is also provided for implementing the powder unit cosmetic pipeline natural production method. It includes a dust-free feeding station for receiving powder raw materials and providing a sealed feeding interface; a mixing device connected to the dust-free feeding station via a sealed feeding port for closed mixing of the powder raw materials and outputting the mixture; a silo for receiving and sealing the mixture; and a sealed pipeline network connected to the discharge end of the mixing device and the silo for conveying the mixture using natural power under gravity and / or air pressure difference. The system includes a docking cavity for sealingly connecting with the hopper and outputting the mixed material; a feeding unit equipped with a feeding port and a bag-feeding automatic packaging machine, wherein the feeding port is sealed and connected to the docking cavity and the bag-feeding automatic packaging machine for filling the mixed material; and a controller for coordinating and controlling the process of receiving / filling the bag-feeding automatic packaging machine, mixing the mixing equipment, conveying the sealed pipeline network, docking the hopper with the docking cavity and the feeding port, and the feeding process of the feeding unit.

[0022] In one embodiment, the discharge port, the docking cavity, and / or the hopper are provided with a sealing docking assembly and an airtightness self-testing assembly; the airtightness self-testing assembly includes a pressure sensor and a pressurization / vacuuming actuator; the controller calculates the pressure retention rate based on the real-time pressure data returned by the pressure sensor, determines the sealing status of the sealed detection cavity formed by the hopper discharge end, the docking cavity, and the discharge port through the pressure retention rate, and outputs an interlock signal to prevent the valve of the docking cavity from being opened when the pressure retention rate is unqualified.

[0023] In one embodiment, the sealed pipeline network is provided with segmented valve groups and differential pressure monitoring components; the controller performs time-sequential opening and closing control on each segmented valve group based on the real-time pressure data returned by the differential pressure monitoring components and the preset differential pressure window, so as to achieve stable control and abnormal interruption of the natural power transport of the mixture.

[0024] In one embodiment, the segmented valve group includes a process valve group and / or a check valve group, wherein the process valve group and / or the check valve group are located between two conveying segments of the sealed piping network and / or within the conveying segments to form unidirectional flow and segment isolation, thereby blocking the backflow of the mixture and communication with external equipment during process switching or abnormal interlocking.

[0025] In one embodiment, the controller includes a process coordination module, which is used to receive material preparation information and material request information and generate release and interlocking instructions, and to generate batch traceability records including timestamps for material feeding, mixing, conveying, docking self-inspection and unloading.

[0026] The beneficial effects of this invention are as follows:

[0027] (1) Significantly reduces the risk of contamination during the production of powder-based cosmetics and improves product quality stability.

[0028] This technical solution employs continuous processes such as sealed feeding, closed mixing, sealed pipeline transfer, and sealed filling to ensure that powder raw materials and mixtures flow within a closed pipeline or sealed container throughout the entire feeding, mixing, conveying, and filling process. This effectively avoids the problem of materials being exposed to the air environment and contaminated by dust, microorganisms, and human contact in traditional open or semi-open production processes, thereby reducing the risk of contamination at the source and significantly improving the consistency and stability of the quality of powder-based cosmetic products.

[0029] (2) Improve the controllability of powder mixing and feeding processes, and reduce the impact of human operation on quality.

[0030] The technical solution clearly states that the pre-set product formula process is used to feed the materials sequentially, and timed mixing is carried out in a closed mixing device. This helps to improve the uniformity and repeatability of powder mixing, reduce the problem of uneven mixing caused by improper feeding sequence or human operation differences, and thus further ensure the stability and controllability of finished product quality.

[0031] (3) Utilize natural power to achieve material transportation, reduce equipment complexity and minimize disturbance to the external environment.

[0032] This technical solution uses gravity and / or air pressure difference as the driving force for material conveying, so that the mixed material is naturally transferred to the silo in the sealed pipeline to complete the filling and sealing. This avoids the risk of secondary pollution caused by equipment openings and exposed transmission components in traditional mechanical conveying methods. At the same time, it reduces the use of complex conveying equipment, which helps to simplify the production structure and reduce maintenance difficulty.

[0033] (4) Achieve a sealed connection between the feeding and filling processes to improve product safety.

[0034] The separate docking chamber allows for a sealed connection between the discharge end of the hopper and the discharge port of the unloading station. The mixed material enters the bag-type automatic packaging machine directly through the discharge port to complete the filling process, avoiding open operation during the unloading and filling stages. This effectively prevents external contaminants from entering the material system before the final product is formed, further improving the product safety of powder unit cosmetics.

[0035] (5) Improve the stability and reliability of the overall powder unit cosmetic production process.

[0036] By combining the aforementioned sealed, continuous, and naturally powered conveying processes, this technical solution can effectively address the issues of high contamination risk and unstable quality and safety in the production process of powder-based cosmetics in existing technologies without significantly increasing process complexity. It provides a reliable technical path for achieving stable production of high-quality powder-based cosmetics.

[0037] In summary, this technical solution, through the coordinated use of sealed feeding, closed mixing, natural pipeline transport based on gravity and / or air pressure difference, and sealed connection during the feeding and filling stages, ensures that the powder unit cosmetics remain within a closed and controllable material flow path throughout the entire formulation and filling process. This effectively avoids the risk of external contamination caused by open operations in existing technologies. Furthermore, the rational design of the feeding sequence, mixing process, and material transfer methods improves the stability and repeatability of the production process. Therefore, this invention not only significantly improves the stability of product quality and safety in powder unit cosmetics but also provides a feasible and effective technical solution for the clean, continuous, and reliable production of powder unit cosmetics.

[0051] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0052] The specific implementation provides a natural production method and intelligent integrated system for powder unit cosmetic pipelines. This method is applicable to the formulation and filling production of powder unit cosmetics. It includes feeding weighed powder raw materials into a dust-free feeding station, introducing them into a mixing device through a sealed feeding port, following a preset product formula feeding sequence; the powder raw materials are then mixed in a closed system within the mixing device to obtain a mixed material; gravity and air pressure difference are used as the driving force for transferring the mixed material to a silo within a sealed pipeline and completing the filling and sealing process; the silo is transferred to a discharge station, and a connecting cavity is used to seal and connect with the discharge ports of both the silo and the discharge station, allowing the mixed material to be discharged to a bag-type automatic packaging machine for filling. By enabling the material to complete the entire process of feeding, mixing, conveying, and filling within a closed pipeline or sealed container path, the risk of contamination during production is effectively reduced, and the stability of the quality and safety of powder unit cosmetic products is improved. This effectively solves the technical problems of existing powder unit cosmetic production processes being highly open and susceptible to contamination, resulting in unstable product quality and safety.

[0053] The first implementation of the natural production method for powder unit cosmetic pipelines, for example Figure 1As shown, it is applicable to the formulation and filling production of powder unit cosmetics, including, S1, sealed feeding: the weighed powder raw materials are put into the dust-free feeding station and introduced into the mixing equipment through the sealed feeding port, and the powder raw materials are fed in sequence according to the preset product formula process feeding order.

[0054] S2. Closed mixing: The powder raw materials are mixed in the mixing equipment. After mixing for 15 minutes, a mixed material is obtained.

[0055] S3. Natural Power Pipeline Transfer: Using gravity and / or air pressure difference as the driving force for conveying, the mixed material is transferred to the silo in the sealed pipeline and the filling and sealing are completed.

[0056] S4. Sealed feeding and filling: The hopper is transferred to the feeding station. The two ends of the separately set sealing connection docking cavity are respectively sealed and connected to the feeding port of the feeding station and the discharge end of the hopper. The mixed material in the hopper is fed into the bag-type automatic packaging machine through the feeding port to complete the filling.

[0057] Throughout the S1 to S4 processes, materials flow within a closed pipeline / sealed container path to reduce the risk of external contamination and improve the stability of product quality and safety.

[0058] Specifically, compared with the existing technical problems of high openness, susceptibility to contamination, and unstable product quality and safety in the production process of powder-based cosmetics, the natural production method of powder-based cosmetic pipelines provided by this technical solution has at least the following technical advantages: significantly reducing the risk of contamination in the production process of powder-based cosmetics and improving the stability of product quality; this technical solution, through continuous processes such as sealed feeding, closed mixing, sealed pipeline transfer, and sealed feeding and filling, ensures that the powder raw materials and mixed materials always flow in a closed pipeline or sealed container path throughout the entire process of feeding, mixing, conveying, and filling, effectively avoiding the problem of materials being exposed to the air environment and contaminated by dust, microorganisms, and human contact in traditional open or semi-open production processes, reducing the risk of contamination from the source, and significantly improving the consistency and stability of the quality of powder-based cosmetic products.

[0059] Improving the controllability of powder mixing and feeding processes reduces the impact of human operation on quality. The feeding steps of the technical solution clearly adopt the preset product formula process feeding sequence and carry out timed mixing in a closed mixing equipment. This helps to improve the uniformity and repeatability of powder mixing, reduce the problem of uneven mixing caused by improper feeding sequence or human operation differences, and thus further ensure the stability and controllability of finished product quality.

[0060] This technology utilizes natural power to achieve material conveying, reducing equipment complexity and minimizing disturbance to the external environment. It employs gravity and / or air pressure difference as the driving force for material conveying, allowing the mixed material to naturally transfer to the silo within the sealed pipeline to complete the filling and sealing process. This avoids the risk of secondary pollution caused by equipment openings and exposed transmission components in traditional mechanical conveying methods. It also reduces the use of complex conveying equipment, which helps to simplify the production structure and reduce maintenance difficulty.

[0061] Achieving a sealed connection between the feeding and filling processes enhances product safety. Through a separately designed docking cavity, the discharge end of the hopper and the feeding port of the feeding station are sealed together. The mixed material directly enters the bag-type automatic packaging machine through the feeding port to complete the filling, avoiding open operation during the feeding and filling stages. This effectively prevents external contaminants from entering the material system before the final product is formed, further improving the product safety of powder unit cosmetics.

[0062] This technology improves the stability and reliability of the powder unit cosmetic production process. Through the synergistic combination of the aforementioned sealed, continuous, and naturally powered conveying processes, this technical solution can effectively solve the problems of high contamination risk and unstable quality and safety in the existing powder unit cosmetic production process without significantly increasing process complexity. It provides a reliable technical path for achieving stable production of high-quality powder unit cosmetics.

[0063] In summary, this technical solution, through the coordinated use of sealed feeding, closed mixing, natural pipeline transport based on gravity and / or air pressure difference, and sealed connection during the feeding and filling stages, ensures that the powder unit cosmetics remain within a closed and controllable material flow path throughout the entire formulation and filling process. This effectively avoids the risk of external contamination caused by open operations in existing technologies. Furthermore, the rational design of the feeding sequence, mixing process, and material transfer methods improves the stability and repeatability of the production process. Therefore, this invention not only significantly improves the stability of product quality and safety in powder unit cosmetics but also provides a feasible and effective technical solution for the clean, continuous, and reliable production of powder unit cosmetics.

[0064] As one alternative implementation method:

[0065] The specific structure of the above-mentioned mixing equipment is that it is a single-shaft paddle mixer.

[0066] In application, the single-shaft paddle mixer, through its paddle structure arranged along a single axis of rotation, creates a mixing motion in the sealed mixing chamber that combines axial tumbling and radial shearing, thereby achieving uniform mixing of the powder materials in a short time. This structure avoids the increased number of sealing points associated with multi-shaft, multi-drive structures, reducing the risk of leakage or external contaminant intrusion during long-term operation. Furthermore, in conjunction with the sealed feeding, sealed mixing, and subsequent sealed pipeline conveying processes of this invention, the mixed material, after achieving an initial homogeneous state, can directly enter the subsequent transfer process without exposure to the external environment, reducing the possibility of contamination introduction at the source.

[0067] By employing a single-shaft paddle mixer and limiting the mixing time, the mixing quality of powder-based cosmetics exhibits good repeatability and stability, effectively solving the problem of unstable powder mixing quality caused by the complexity of mixing equipment and the difficulty in sealing in existing technologies.

[0068] The shape, number, speed range, and internal structure of the blades of the single-shaft paddle mixer can be adjusted according to the characteristics of different powder formulations. Propeller blades, baffle blades, or detachable blade structures can be used to further adapt to cosmetic raw materials with different particle sizes and flowability.

[0069] To improve the airtight safety of the mixture during conveying and transfer, and to prevent foreign matter from contaminating the mixture, in S3 and / or S4, an airtightness self-test is performed before and / or after the sealing connection between the hopper and the docking cavity and the discharge port is completed. The airtightness self-test includes: pressurizing or evacuating the docking cavity and / or the airtightness detection cavity formed by the discharge end of the hopper, the docking cavity and the discharge port, and testing the pressure retention rate. When the pressure retention rate does not meet the preset threshold, an interlock signal is output and material feeding to the bag-feeding automatic packaging machine is prohibited.

[0070] Before and / or after the sealing connection is completed in the hopper, docking cavity and discharge port, the sealing status is quantitatively verified by airtightness self-inspection, so that the sealing connection is transformed from the traditional "structural seal" to "detectable and identifiable sealing status".

[0071] In practice, the system pressurizes or evacuates the docking cavity and / or the sealed detection cavity formed by the material outlet, docking cavity, and discharge port, and monitors pressure changes within a predetermined time window to calculate the pressure retention rate, thereby determining whether the sealing connection is reliable. When the pressure retention rate does not meet the preset threshold, the system uses an interlocking mechanism to prohibit the material discharge action, preventing the filling operation from continuing under insufficient sealing conditions.

[0072] The sealing detection and interlocking mechanism works in conjunction with the sealing feeding and filling process to effectively prevent external air, dust and microorganisms from entering the mixed material at key feeding points, significantly improving the safety and reliability of the conveying and filling stages, and solving the problem that the sealing effectiveness is difficult to verify at the feeding connection point in the existing technology and that it is easy to become a weak point for contamination.

[0073] The pressurization or vacuuming method, pressure retention rate threshold setting, and test duration for airtightness self-test need to be adjusted according to the product's cleanliness level requirements. In addition, the airtightness self-test is also linked with functions such as alarm prompts, automatic retests, or seal replacement prompts to further enhance the system's intelligence level.

[0074] The second embodiment of the natural production method of powder unit cosmetic pipelines differs from the first embodiment in that segmented differential pressure control is applied to the sealed pipeline: the sealed pipeline is divided into at least two conveying sections, and segmented valve groups and differential pressure monitoring points are set in each conveying section; each conveying section is controlled to open and close sequentially within a preset differential pressure window, so as to achieve stable and controllable natural power conveying without relying on continuous motor-driven conveying.

[0075] Among them, using gravity or differential pressure control can avoid the introduction of pollution sources by driving electric equipment for conveying; when using differential pressure or air pressure control, the introduced air passes through the set fresh air filtration equipment and is filtered by the nano-level filter element to obtain clean air, which is used to drive the mixed material to move in the sealed pipe, while avoiding the introduction of pollution sources.

[0076] When applied, by dividing the sealed pipeline into at least two conveying sections and setting up segmented valve groups and differential pressure monitoring points in each conveying section, the transfer process of the mixture is transformed from an overall uncontrollable pipeline flow into a segmented and controllable natural power conveying process.

[0077] The control system, based on the real-time differential pressure of each conveying segment, sequentially opens and closes segmental valve groups within a preset differential pressure window, thereby guiding the mixed material to be transported downstream stably and orderly under the influence of gravity and / or air pressure differential. Compared with traditional electric conveying equipment, this method avoids additional pollution sources generated by components such as motors and transmission mechanisms during the conveying process and reduces disturbance to the external environment during equipment operation. Simultaneously, when differential pressure or air pressure is used for auxiliary conveying, the air entering the system is filtered at the nanoscale through a fresh air filtration device, ensuring that the gas used to drive the movement of the mixed material is itself clean, thus achieving the conveying function while avoiding the introduction of new pollution risks. Through the coordinated control of multiple devices, the system effectively solves the problems of existing technologies where powder conveying relies on electric equipment, carries high pollution risks, and is difficult to precisely control the conveying process.

[0078] The segmented valve group adopts the form of process valve, check valve or a combination of both, and the number and location of differential pressure monitoring points are adjusted according to the pipeline length and height difference; the filtration level of the fresh air filtration equipment also needs to be selected according to the product cleanliness requirements to avoid performance waste and increased production costs.

[0079] The third embodiment of the natural production method for powder unit cosmetic pipelines differs from the first embodiment in that it establishes a cross-station process collaborative closed-loop control, including: before feeding materials, the upstream station sends a material feeding preparation information to the station where the mixing equipment is located and completes the release; before discharging materials, the downstream station sends a material request information to the station where the silo is located and completes the release.

[0080] By using controllers installed at multiple workstations, the controllers release and interlock the mixing of the mixing equipment, the transfer of the sealed pipeline, the docking self-inspection of the hopper and docking chamber and the discharge port, and the discharge action of the discharge station based on the preparation of feeding information and the material request information, and generate batch traceability records.

[0081] By establishing a closed-loop control mechanism for process collaboration among multiple workstations, the processes of feeding, mixing, conveying, and unloading of powder cosmetics are no longer independent operations, but rather form a collaborative process that is interconnected and mutually constrained.

[0082] Specifically, before feeding materials, the upstream station sends a material feeding preparation message to the mixing equipment station and completes the release. Before unloading materials, the downstream station sends a material request message to the silo station and completes the release. Based on the above information, the controller performs unified scheduling and interlocking control of mixing, pipeline transfer, docking airtightness self-inspection, and unloading actions. This control method can avoid misoperation or abnormal unloading caused by asynchronous processes or inconsistent states. At the same time, by generating batch traceability records containing key process timestamps, it provides data support for subsequent quality analysis and problem tracing. Through this process collaborative closed-loop control, the problem of fragmented production processes in powder unit cosmetics and difficulty in timely blocking of abnormal states in existing technologies is effectively solved, further improving the safety and reliability of the overall production process.

[0083] Material preparation and request information are transmitted via wired or wireless communication; batch traceability records are further integrated with the production management system or quality management system to achieve higher-level data analysis and production optimization.

[0084] Based on the above embodiments of the natural production method for powder unit cosmetic pipelines, a powder unit cosmetic intelligent joint system is provided for implementing the natural production method for powder unit cosmetic pipelines, such as... Figure 2As shown, the system includes a dust-free feeding station 1 for receiving powder raw materials 12 and providing a sealed feeding interface 11; a mixing device 2 connected to the dust-free feeding station 1 via a sealed feeding port 21 for sealingly mixing the powder raw materials 12 and outputting a mixed material 22; a silo 3 for receiving and sealingly storing the mixed material 22; a sealed pipeline network 4 connected to the discharge end of the mixing device 2 and the silo 3 for conveying the mixed material 22 by natural power under gravity and / or air pressure difference; and a docking cavity 5 for connecting with the silo 3. The system includes a sealed connection and output of the mixed material 22; a feeding unit 6, which has a feeding port 61 and a bag-feeding automatic packaging machine 62. The feeding port 61 is sealed and connected to the docking cavity 5 and the bag-feeding automatic packaging machine 62, and is used to fill the mixed material 22; and a controller 7, which is used to coordinate and control the process of receiving / filling the bag-feeding automatic packaging machine 62, mixing the mixing equipment 2, conveying the sealed pipeline network 4, docking the hopper 3 with the docking cavity 5 and the feeding port 61, and feeding the feeding unit 6.

[0085] When applied, the powder unit cosmetic intelligent joint system integrates the dust-free feeding station 1, mixing equipment 2, sealed pipeline network 4, silo 3, docking cavity 5, discharge port 61 and bag-type automatic packaging machine 62 in a structured manner, and the controller 7 coordinates the operation status of each unit in a unified manner, so that the powder raw material 12 is always in a closed, continuous and controlled system environment from the beginning of feeding to the end of filling.

[0086] The controller 7 is connected to the dust-free feeding station 1, the mixing equipment 2, the sealed pipeline network 4, the control and conveying components, the silo 3, the docking cavity 5, and the unloading unit 6.

[0087] This system structure allows the mixture 22 to be connected between different processes without open transfer, effectively avoiding the dust, microorganisms and human contact contamination problems introduced by the dispersed equipment and open interfaces in the prior art; at the same time, through the coordinated control of mixing, conveying, docking and unloading actions, it prevents abnormal unloading or misoperation caused by asynchronous processes or mismatched states, thereby improving the stability and safety of the powder unit cosmetic production process as a whole.

[0088] Each functional unit in the system needs to be modularly configured according to the production scale, such as setting up multiple material bins 3 or parallel feeding units 6 to adapt to different production capacity requirements; the controller 7 also interfaces with the upper production management system to realize production plan issuance, status monitoring and centralized data management.

[0089] The discharge port 61, the docking cavity 5 and / or the hopper 3 are equipped with a sealing docking assembly 8 and an airtightness self-testing assembly 9. The airtightness self-testing assembly 9 includes a pressure sensor and a pressurization / vacuuming actuator. The controller 7 calculates the pressure retention rate based on the real-time pressure data returned by the pressure sensor, determines the sealing status of the sealed detection cavity formed by the discharge end of the hopper 3, the docking cavity 5 and the discharge port 61 through the pressure retention rate, and outputs an interlock signal to prevent the valve of the docking cavity 5 from being opened when the pressure retention rate is unqualified.

[0090] By setting sealing docking components 8 and airtightness self-inspection components 9 at the discharge port 61, docking cavity 5 and / or hopper 3, the system can quantitatively verify the sealing status of key sealing nodes before material discharge.

[0091] The sealing assembly 8 is a sealing ring or sealing joint provided at the discharge port 61, the docking cavity 5 and / or the discharge end of the hopper 3.

[0092] In the specific execution process, after the material hopper 3 discharge end, docking cavity 5 and discharge port 61 are sealed and connected, the formed sealed detection cavity is subjected to detection conditions by pressurization or vacuuming, and pressure change data is collected within the preset time window to calculate the pressure retention rate; the controller 7 determines whether the seal is reliable based on whether the pressure retention rate meets the preset threshold, and if it is unqualified, it prohibits the opening of the docking cavity 5 valve through interlock control, thereby blocking the mixed material 22 from entering the bag-feeding automatic packaging machine 62.

[0093] The quantitative verification of the sealing status, in synergy with the sealing and unloading structure of the system, transforms the traditional manual confirmation of the sealing status into a detectable and verifiable engineering control method. This effectively solves the problem that the sealing reliability of the unloading connection is difficult to verify and is prone to becoming a weak point for contamination in the existing technology, and significantly improves the safety of system operation.

[0094] The detection method, detection time, and threshold for pressure retention rate need to be configured according to the cleanliness requirements of different powder unit cosmetics; in addition, the airtightness self-test results are linked with alarm, automatic retest, or maintenance reminder functions to improve the intelligence and maintainability of the system.

[0095] In addition, the sealed pipeline network 4 is equipped with segmented valve groups 41 and differential pressure monitoring components 42; the controller 7 performs timed opening and closing control on each segmented valve group 41 based on the real-time pressure data returned by the differential pressure monitoring components 42 and the preset differential pressure window, so as to achieve stable control and abnormal blocking of the natural power conveyed mixed material 22.

[0096] The controller 7 is communicatively connected to the segmented valve group 41 and the differential pressure monitoring component 42 in the sealed pipeline network 4.

[0097] In application, by setting segmented valve groups 41 and differential pressure monitoring components 42 in the sealed pipeline network 4, the conveying process of the mixed material 22 is transformed from an overall uncontrollable pipeline flow to a segmented and controllable natural power conveying process; the controller 7 obtains the differential pressure information of each conveying segment in real time, and performs timed opening and closing control on the segmented valve groups 41 within the preset differential pressure window, so that the mixed material 22 is stably transferred according to a predetermined path and rhythm under the action of gravity and / or air pressure difference.

[0098] The valve assembly and differential pressure detection and control system work together with the sealing structure to avoid pollution sources and vibration disturbances introduced by mechanical drive devices such as motors and screw conveyors. At the same time, it can promptly execute blocking control when the differential pressure is abnormal or the conveying is abnormal to prevent material backflow or abnormal flow, thereby improving the controllability and safety of the conveying process and solving the problems of existing powder conveying technology that rely on mechanical equipment, have high pollution risks, and are difficult to control precisely.

[0099] The number and location of differential pressure monitoring components 42 are adjusted according to the pipeline length, drop and wiring path; when differential pressure is used for assisted transportation, a fresh air filtration device is configured to filter the gas entering the system to further reduce the possibility of external pollution being introduced.

[0100] Regarding the specific composition of the above-mentioned segmented valve group 41, the segmented valve group 41 includes a process valve group and / or a check valve group. The process valve group and / or check valve group are located between and / or within the two conveying sections of the sealed pipeline network 4 to form unidirectional flow and segment isolation, thereby blocking the backflow of the mixture 22 and the connection with external equipment during process switching or abnormal interlocking.

[0101] In application, process valve assemblies and / or check valve assemblies are installed between and / or within different conveying sections of the sealed piping network 4 to ensure a unidirectional flow path for the mixture 22 during normal conveying and to achieve rapid isolation during process switching, abnormal interlocking, or pressure differential abnormalities. The process valve assemblies are used to actively open and close the conveying channels under the control commands of the controller 7, while the check valve assemblies are used to automatically block backflow in the absence of a control signal or under reverse pressure. Both work in conjunction with the differential pressure monitoring component 42 and the controller 7 to effectively prevent backflow, backflow, or unintended connection with external equipment of the mixture 22 under abnormal conditions, thereby further ensuring the operational safety and cleanliness of the sealed piping system.

[0102] The process valve assembly adopts electric valves, pneumatic valves, or a combination thereof, while the check valve assembly needs to be selected according to the powder characteristics, using flap type, spring type, or gravity type structures to adapt to the flow characteristics of different powder units in cosmetics.

[0103] Regarding the specific control modules of the aforementioned controller 7, controller 7 includes a process coordination module, which is used to receive preparation feeding information and material request information and generate release and interlocking instructions, and is used to generate batch traceability records containing feeding, mixing, conveying, docking self-inspection and unloading timestamps.

[0104] By setting up a process coordination module in controller 7, key processes such as feeding, mixing, conveying, docking self-inspection and unloading no longer operate in isolation, but form a closed-loop control process that is interconnected and mutually restrictive.

[0105] In practice, after receiving the material preparation and material request information, the process coordination module judges the execution conditions of each process and only issues a release command when the preset state requirements are met. It also triggers interlock control in a timely manner when any abnormality occurs in any link. At the same time, the process coordination module generates batch traceability records with timestamps for each key action, providing a data foundation for subsequent quality analysis, anomaly tracing, and production optimization. Thus, the collaborative control effectively solves the problems of process fragmentation and difficulty in timely blocking of abnormal states in the existing technology, further improving the overall reliability and manageability of the powder unit cosmetic production system.

[0106] Furthermore, batch traceability records are integrated with the enterprise's production management system or quality management system to achieve cross-system data analysis and quality traceability; the process collaboration module adds access control or remote monitoring functions as needed.

[0107] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
