Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments of the present invention. It should be understood that the present invention is not limited to the example embodiments used only to explain the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. In addition, it should be noted that, for the convenience of description, only the parts related to the present invention, rather than all, are shown in the drawings.

[0023] Example 1

[0024] Figure 1 The figure is a flow chart of a production control method for product packaging according to the present invention, wherein the method comprises:

[0025] A predetermined two-dimensional feature analysis is performed on the target product to obtain target packaging requirements for the target product packaging, where the target product packaging refers to packaging used for the target product, and the target packaging requirements include multiple requirements.

[0026] Specifically, first, the two-dimensional characteristics of the target product are analyzed and obtained to obtain the target packaging requirements of the target product, which helps to generate a packaging solution that meets the target product.

[0027] In some embodiments, the predetermined dual dimensions include a functional dimension and an environmental dimension of packaging, wherein the functional dimension includes multiple functional requirements; the multiple functional requirements and the environmental requirements of the environmental dimension constitute the target packaging requirements.

[0028] Specifically, the predetermined two-dimensional feature analysis refers to a comprehensive analysis of the target product based on the functional dimension and environmental dimension of the packaging, so as to meet the functional requirements and environmental requirements of the product packaging and design a suitable packaging solution for the product.

[0029] Specifically, the functional dimension involves the basic functions that packaging must have, and is related to product protection, storage, transportation, display, etc. For example, the functional dimension includes physical protection requirements, sealing requirements, portability and stacking requirements, display requirements, etc. For example, for Band-Aid products, the functional dimensions include waterproof, dustproof, and moisture-proof (physical protection requirements and sealing requirements), as light and compact as possible for easy carrying (portability and stacking requirements), and independent packaging for quick user access (convenient use requirement).

[0030] Specifically, the environmental dimension is used to ensure that the materials and design of Band-Aid packaging can reduce the impact on the environment and comply with the concepts of environmental protection and sustainable development. For example, the environmental dimension includes: giving priority to recyclable and biodegradable environmentally friendly materials for packaging to reduce the impact on the environment. For example, bio-based plastics, PLA (polylactic acid), etc., to ensure that the packaging can enter the recycling system after use; through design optimization, unnecessary packaging materials are reduced, and the carbon footprint of production and transportation is reduced. For example, compact packaging boxes are designed to avoid excessive packaging; and degradable materials are used, especially in disposable packaging, such as the outer layer of single-piece packaging using degradable bioplastics.

[0031] Furthermore, based on the analysis of functional and environmental dimensions, the target packaging requirements for Band-Aid products were generated. These target packaging requirements include multiple quantitative demand targets (i.e., multiple requirements), such as water permeability index, tensile strength index, gas permeability index, portability index (such as volume, thickness), proportion of recyclable materials, biodegradability requirements, carbon footprint requirements, etc.

[0032] Through quantitative analysis of both functional and environmental dimensions, we ensured that the target packaging requirements accurately reflected the dual requirements of effectively protecting the product and complying with environmental standards. The resulting target packaging solution not only enhanced product functionality but also reduced environmental impact.

[0033] A first material of a first requirement among the multiple requirements is matched in a material database, and the first material is analyzed to generate a target packaging material solution.

[0034] Specifically, the material database includes a variety of materials suitable for multi-layer coextrusion production: plastics such as high-density polyethylene (HDPE), polypropylene (PP), or polyester (PET); and paper materials such as kraft paper, waxed paper, eco-friendly cardboard, and cellulose. By matching requirements within the material database, you can find materials that meet the functional and environmental requirements of your target product.

[0035] Specifically, each material in the material database corresponds to a data group, which is used to record the specific functional performance and environmental performance of the material. For example, it includes: moisture resistance (such as water vapor transmission rate WVTR), tear resistance (such as tear strength), waterproof performance (such as water permeability), heat resistance (such as melting point temperature), and sealing (such as gas permeability).

[0036] In some embodiments, the method further comprises:

[0037] Obtain a first functional requirement value of the target product for a first functional requirement, where the first functional requirement refers to any one of the multiple functional requirements; extract a first material from the material database, where the first material has a first data group, and the first data group includes a first indicator threshold of a first functional indicator, where the first functional indicator corresponds to the first functional requirement; under the environmental protection requirement, determine whether the first indicator threshold meets the first functional requirement value; if so, add the first material to a first candidate material set for the first functional requirement; the first data group also includes a first environmental protection threshold of the first material, and then the first candidate material set is sorted in descending order based on the first environmental protection threshold to obtain a first candidate material descending order table; obtain a first target material that meets the first functional requirement based on the first candidate material descending order table; form a target material set for the target product packaging based on the first target material, and generate the target packaging material solution based on the target material set.

[0038] Specifically, first determine the specific value of the first functional requirement based on the specific requirements of the target product. For example, for the moisture-proof requirement of a band-aid, the moisture-proof performance requirement can be set to a water vapor permeability of less than 0.5g / m 2 24 hours. The first functional requirement is randomly selected from multiple functional requirements. Then, under the premise of meeting environmental protection requirements, a first material that meets the first functional requirement is extracted from the material database as the first candidate material set for the first functional requirement.

[0039] Specifically, the functional index threshold refers to the standard value of the index value corresponding to the first material and the first functional requirement, representing the typical performance of the first material in terms of the first functional requirement.

[0040] Furthermore, among the materials that meet the functional requirements (i.e., the first set of candidate materials), each material is sorted in descending order based on its environmental performance, thereby ensuring that materials with good environmental performance (high recyclability and low carbon footprint) are selected first.

[0041] Furthermore, the system traverses multiple functional requirements and randomly extracts materials, updates the first functional requirement, and repeats the above extraction, comparison, screening, and sorting process to obtain a descending list of candidate materials corresponding to the multiple functional requirements. Multiple target materials corresponding to the multiple functional requirements are then determined, generating a target material set for the target product packaging. This target material set includes multiple base materials required for the target product packaging.

[0042] In some implementations, the method further includes: sequentially acquiring a target mildew-proof material and a target additive material, and adding the target mildew-proof material and the target additive material to the target material set.

[0043] Specifically, the target material set includes, in addition to the base material, target mildew-resistant materials and target additive materials. The target mildew-resistant materials are used to inhibit mildew growth, while the target additive materials are other auxiliary materials used to improve the performance of multi-layer co-extruded products, such as adhesives, modifiers, and cross-linking agents. For example, in the target material set, the product-contact safe material is the inner layer of the target packaging, the middle layer is treated with a mildew inhibitor, and the outer layer is a moisture-proof and wear-resistant material.

[0044] Furthermore, the production control method for a product packaging is applied to a production control platform for a product packaging, the production control platform for a product packaging being communicatively connected to a co-extruder, and the production control method for a product packaging comprises:

[0045] Randomly obtain a first arbitrary material from the target material set and initialize a first arbitrary material thickness of the first arbitrary material; perform a co-extrusion simulation of the co-extruder based on the first arbitrary material thickness to obtain a first simulated prefabricated packaging body; read predetermined prefabrication performance indicators, and perform a comprehensive evaluation of the first simulated prefabricated packaging body based on the predetermined prefabrication performance indicators to obtain a first simulation comprehensive index; when the first simulation comprehensive index reaches a comprehensive threshold value, use the first arbitrary material thickness as a first production thickness decision for the first arbitrary material, and generate the target packaging material solution.

[0046] Specifically, the target product packaging is produced by a co-extruder that is communicatively connected to a production control platform for product packaging. The co-extruder also includes supporting key equipment such as a casting machine, a stretching machine, a cooling and shaping device, and a cutting and winding machine.

[0047] Specifically, a first arbitrary material is randomly obtained from the target material set and initially set, including setting the initial thickness of the material for subsequent simulation operations. Exemplarily, the initial thickness is set based on an empirical value or through previous experimental data.

[0048] Specifically, co-extrusion simulation simulates the co-extrusion process of multi-layer materials to predict the performance of the materials in production, such as simulated sample production. For example, to perform co-extrusion simulation, first, check the operating status of key equipment such as the co-extruder, cast film machine, stretching machine, cooling and shaping device, cutting and winding machine, ensure that they are in good working condition, and prepare other auxiliary materials, such as adhesives, additives, etc. Then, according to production requirements, debug the equipment and set appropriate process parameters (first arbitrary material thickness). Next, the selected plastic substrate, mildewproof agent and other additives are put into the melt blending equipment in a certain proportion and fully mixed to form a uniform molten mixture. Then, the molten mixture is fed into the co-extruder and extruded simultaneously through multiple extruder heads to form a multi-layer film. During the extrusion process, by precisely controlling the flow rate and temperature of each layer of material, it is ensured that each layer of material can be tightly bonded to form a uniform composite layer structure. Then, the extruded multilayer film is stretched longitudinally and transversely to increase its strength and toughness. After stretching, the film is sent to a cooling and shaping device for cooling treatment to stabilize its shape and improve dimensional accuracy; the cooled and shaped film is cut and rolled according to a predetermined width and length to form the required first simulated prefabricated packaging body.

[0049] Specifically, a comprehensive evaluation is performed on the first simulated prefabricated packaging body based on predetermined prefabricated performance indicators to obtain a first simulation comprehensive index; the first simulation comprehensive index is used to quantitatively evaluate the performance of the first simulated prefabricated packaging body. Exemplarily, the first simulation comprehensive index is a weighted sum of the achievement rates of multiple performance indicators compared to the predetermined prefabricated performance indicators.

[0050] Furthermore, the compliance of the first simulated prefabricated packaging body is judged based on the comprehensive threshold value. When the comprehensive index reaches or exceeds the comprehensive threshold value, the current simulation result can be considered qualified, and the thickness of the first arbitrary material can be used as the first production thickness decision of the first arbitrary material, thereby obtaining the corresponding target packaging material solution.

[0051] In some embodiments, the predetermined prefabrication performance indicators include prefabrication adhesion and prefabrication energy efficiency.

[0052] Specifically, material thickness directly impacts its functionality, such as moisture resistance and pressure resistance. Generally, increasing thickness enhances moisture and shock resistance, but may weaken the material's adhesion. Therefore, the performance of prefabricated packaging must be evaluated based on both adhesion and functionality.

[0053] Specifically, prefabrication adhesion refers to the strength of the bond between the layers of material. Excessive material thickness may reduce adhesion, leading to separation or shedding between layers, thus compromising the integrity of the packaging material. Energy efficiency refers to the degree to which a material meets functional requirements (such as moisture resistance, pressure resistance, and shock resistance). Generally speaking, increasing material thickness can enhance energy efficiency, but this will affect adhesion.

[0054] A target co-extrusion strategy is generated in combination with the target packaging material solution, and the execution process of the target co-extrusion strategy is dynamically monitored to obtain real-time monitoring information.

[0055] Specifically, the target packaging material solution serves as the target co-extrusion strategy, controlling the aforementioned co-extruder and its associated key equipment, such as the casting machine, stretching machine, cooling and shaping device, and cutting and winding machine, to produce the target packaging material. Exemplarily, the product packaging production control platform converts the target packaging material solution into a target co-extrusion strategy (e.g., control instructions and G-code) understandable to the co-extruder. Through communication with the co-extruder, the platform controls and dynamically monitors the execution of the target co-extrusion strategy.

[0056] Optionally, the real-time monitoring information includes the operating status information of key equipment such as the co-extruder and the supporting cast film machine, stretching machine, cooling and shaping device, cutting and winding machine, etc., which includes, for example, extrusion temperature, pressure, extrusion flow, extrusion thickness, cooling wind speed, cooling temperature, film thickness and uniformity, stretching ratio and direction, film mechanical properties and appearance quality, shaping effect and dimensional stability, winding tension and uniformity, cutting accuracy and speed, etc.

[0057] By generating a target coextrusion strategy and dynamically monitoring the execution process, it helps to promptly identify existing production problems and ensure the quality of packaging materials and production efficiency.

[0058] When the real-time status index obtained by analyzing the real-time monitoring information does not meet a predetermined status threshold, a control instruction is issued.

[0059] In some embodiments, the method comprises:

[0060] The production control platform of the product packaging is also in communication with an online thickness measuring device, and the online thickness measuring device is arranged at a casting machine station. The production control method of the product packaging includes:

[0061] The online thickness measuring device is used to perform dynamic thickness detection on the multi-layer co-extruded material composite on the casting machine to obtain real-time thickness information, which includes multiple thickness data of multiple composite points; multiple thickness characteristic parameters of the multiple thickness data are weighted to obtain the real-time status index; wherein the multiple thickness characteristic parameters include multiple parameters corresponding to predetermined thickness indicators, and the predetermined thickness indicators include at least the maximum thickness difference, the maximum thickness, the minimum thickness and the thickness mean.

[0062] Specifically, online thickness measurement equipment installed at the casting machine station acquires real-time thickness data of the multi-layer co-extruded composite material on the casting machine and outputs real-time thickness information. Optionally, the real-time thickness information is multi-point thickness information of the multi-layer co-extruded composite material. The online thickness measurement equipment uses sensors (such as laser, ultrasonic, and X-ray) to perform non-contact measurement of the material surface to achieve real-time monitoring.

[0063] Specifically, the real-time thickness data is processed to obtain multiple thickness characteristic parameters (such as the maximum thickness, minimum thickness, average thickness at multiple points, and the thickness variation trend across the entire width of the material). These key thickness characteristic parameters are then weighted and calculated to generate a real-time status index. This real-time status index is used to reflect the current production status and determine whether the material thickness is stable and meets production requirements.

[0064] Specifically, when weighting multiple thickness characteristic parameters (such as maximum thickness difference, maximum thickness, minimum thickness, and mean thickness), the weights are adjusted based on the importance of the indicators during the production process. This dynamically adjusted weighting better reflects the target packaging's material preferences and improves the accuracy of state identification.

[0065] Specifically, a predetermined status threshold is used to assess whether production status is normal. When the real-time status index falls below this threshold, it indicates that the material thickness currently in production has deviated from the expected requirement. Accordingly, control instructions must be issued to adjust production parameters to ensure that the material thickness meets the requirements during production. Optionally, the status threshold can be set based on historical production data, process requirements, and product standards.

[0066] The target co-extrusion strategy is optimized based on the control instruction to obtain the target optimal co-extrusion strategy, and dynamic production control of the target product packaging is performed according to the target optimal co-extrusion strategy.

[0067] Specifically, the target co-extrusion strategy is optimized, and the optimization directions include: adjusting the co-extrusion speed of the material, adjusting the temperature of the cast film machine, adjusting the material ratio (such as adjusting the flow rate or ratio of each layer of material, optimizing the thickness distribution of the material), etc.

[0068] Furthermore, the target co-extrusion strategy includes control parameters of predetermined extrusion control indicators of each material in the target material set, wherein the predetermined extrusion control indicators include extrusion speed and extrusion diameter, including:

[0069] Extract a second arbitrary material from the target material set, the second arbitrary material corresponds to a second extrusion strategy, and the second extrusion strategy includes a second extrusion speed and a second extrusion caliber; obtain a second production thickness decision for the second arbitrary material; with the goal of minimizing the thickness deviation between the second arbitrary thickness of the second arbitrary material and the second production thickness decision, optimize the second extrusion speed and the second extrusion caliber to obtain a second optimal extrusion strategy; obtain the target optimal co-extrusion strategy based on the second optimal extrusion strategy.

[0070] Specifically, first, a second arbitrary material is selected from the target material set. Based on the production and process requirements of the material, a corresponding second extrusion strategy (including extrusion speed and extrusion diameter) is extracted. Optionally, the second extrusion strategy is a typical or historically based strategy corresponding to the second arbitrary material. Then, based on the aforementioned method for obtaining the thickness agreement for the first arbitrary material, a second production thickness decision for the second arbitrary material is obtained. It should be understood that for the sake of brevity, this description will not be further elaborated here.

[0071] Specifically, based on the second production thickness decision and combined with the optimization algorithm, the second extrusion speed and the second extrusion diameter of the second arbitrary material are iteratively adjusted to minimize the deviation between the final extruded thickness and the second production thickness decision. At this time, the second extrusion speed and the second extrusion diameter are the second optimal extrusion strategy for the second arbitrary material, that is, the optimal extrusion speed and outlet width that should be used in production of the material.

[0072] Through the above-mentioned dynamic optimization of co-extrusion strategy and optimization of strategy parameters, precise control of multi-layer co-extrusion materials can be achieved, and dynamic adjustments can be made during the production process, thereby improving production efficiency and product quality.

[0073] In summary, the production control method for product packaging provided by the present invention has the following technical effects:

[0074] By performing a preset two-dimensional feature analysis on the target product, the specific packaging requirements for the product are determined. Product packaging is the packaging form suitable for the product, which covers multiple specific requirements. The first of the multiple requirements is matched from the material database, and the corresponding first material is selected and analyzed to generate a target packaging material solution. Based on the target packaging material solution, a target co-extrusion strategy is formulated, and dynamic monitoring and real-time monitoring information are collected during the execution process. When the analysis of the real-time monitoring information shows that the status index is below the preset threshold, the corresponding control instructions are issued. Based on the control instructions, the target co-extrusion strategy is optimized to generate the optimal co-extrusion strategy. Based on this optimal strategy, dynamic production control is implemented for the packaging process of the target product. This achieves the technical effect of improving the moisture and mildew resistance of the packaging and ensuring product quality.

For example, Figure 1 The flow chart of the production control method of a product packaging of the present invention can be shown as follows: Figure 2 The structure shown is implemented.

[0077] Based on the same concept as the production control method for a product packaging in the embodiment, the present invention also provides a production control platform for product packaging, including:

[0083] In some embodiments, the predetermined two dimensions include a functional dimension and an environmental dimension of the packaging, wherein the functional dimension includes multiple functional requirements. The multiple functional requirements and the environmental requirement of the environmental dimension constitute the target packaging requirement.

[0084] Preferably, the material solution pre-construction module 12 also includes an EBS procurement unit and a LIMS quality inspection unit, wherein the EBS procurement unit is used to receive purchase orders, generate corresponding material inspection requirements based on the material inspection information submitted by the warehouse manager, and transmit the material inspection requirements to the LIMS unit; after the quality inspectors complete the inspection of the material inspection requirements according to the material inspection standards, the LIMS unit generates a test report based on the test results, and sends the generated test report to the EBS procurement unit. Materials with qualified test reports are stored in the material database, that is, raw materials that meet the quality standards are the first condition for screening by the co-extrusion module.

[0085] In some embodiments, the material solution pre-configuration module 12 is further configured to:

[0086] Obtain the first functional requirement value of the target product for the first functional requirement, where the first functional requirement refers to any one of the multiple functional requirements. Extract the first material from the material database, where the first material has a first data group, and the first data group includes a first indicator threshold of a first functional indicator, where the first functional indicator corresponds to the first functional requirement. Under the environmental protection requirement, determine whether the first indicator threshold meets the first functional requirement value. If so, add the first material to the first candidate material set for the first functional requirement. The first data group also includes the first environmental protection threshold of the first material, and then the first candidate material set is sorted in descending order based on the first environmental protection threshold to obtain a descending list of first candidate materials. Obtain the first target material that meets the first functional requirement based on the first candidate material descending list. Assemble the target material set for the target product packaging based on the first target material, and generate the target packaging material solution based on the target material set.

[0087] In some implementations, the material solution pre-construction module 12 further includes: sequentially acquiring a target mildew-proof material and a target additive material, and adding the target mildew-proof material and the target additive material to the target material set.

Predetermined prefabrication performance indicators are read, and a comprehensive evaluation of the first simulated prefabricated packaging body is performed based on the predetermined prefabrication performance indicators to obtain a first simulation comprehensive index. When the first simulation comprehensive index reaches a comprehensive threshold, the first arbitrary material thickness is determined as a first production thickness for the first arbitrary material, and a target packaging material solution is generated.

[0090] Furthermore, in the material solution prefabrication module 12, the predetermined prefabrication performance indicators include prefabrication adhesion and prefabrication energy efficiency.
