[0002] The production of plastic cups involves multiple technical fields, including material science, mold design, molding process, automated control and quality inspection. Commonly used plastic materials include polypropylene, polyethylene, polystyrene (PS), polycarbonate and polyethylene terephthalate. Each material has different physical and chemical properties and is suitable for plastic cups with different uses. The mold is a key tool for molding plastic cups. Its design directly affects the dimensional accuracy, surface quality and production efficiency of the product. Common mold types include single-cavity molds, multi-cavity molds, etc.
[0003] At present, in the production management of plastic cups, the filling flow rate, holding time and cooling time are usually designed based on manual experience. However, in the production process of plastic cups, not only may there be different materials added, but the production molds of the plastic cup production line may also be worn.

[0053] Figure 1 A schematic flow chart of a method for regulating and managing the operation of a plastic cup production line provided by the present invention. DETAILED DESCRIPTION
[0054] The embodiment of the present invention solves the technical problem of unreasonable operation of a target plastic cup production line controlled by inherent operation parameters in the prior art by providing a method for controlling the operation of a plastic cup production line.
[0055] The technical solution of the present invention is to solve the above technical problems, and the overall idea is as follows:

[0057] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0058] First of all, the term "and / or" in this article is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.
[0059] In the production process of plastic cups, material addition is one of the steps, and material addition can be divided into batch addition or continuous addition. When adding in batches, the composition of the material may be different, and different compositions require adapted filling flow, holding time, and cooling time. The purpose of the present invention is to intelligently adjust the filling flow, holding time, and cooling time, avoiding the uncertainty of relying solely on manual experience, improving accuracy, reducing labor costs, and improving the intelligence of plastic cup production.
[0060] It is understandable that, although the main applicable situation of the present invention is "addition in batches", it does not mean that the situation of "continuous addition" is not applicable. It is only necessary to identify the plastic cups produced by "continuous addition" as the same batch.
[0061] The present invention provides Figure 1 The operation control management method of a plastic cup production line shown includes steps S11-S16:
[0062] S11, obtaining first operating parameters of a current batch of plastic cups in a target plastic cup production line, the first operating parameters including a first filling flow rate, a first pressure holding time, a first cooling time, and a first production efficiency per unit time.
[0063] The plastic cup production line refers to the production line used to produce plastic cups, and the current batch of plastic cups refers to the plastic cups produced based on the same batch of materials. The components and composition states of the same batch of materials are the same.
[0064] The first filling flow rate refers to the flow rate of material (such as molten plastic) injected into the mold to produce the current batch of plastic cups (the unit can be expressed in L / s); the first holding time refers to the length of time the pressure is maintained in the mold when producing the current batch of plastic cups; the first cooling time refers to the length of time the plastic is cooled and solidified in the mold when producing the current batch of plastic cups; the first unit time production efficiency refers to the speed of producing the current batch of plastic cups (that is, it can be the number of plastic cups produced per unit time, and the length of the unit time can be determined based on actual conditions).
[0065] Emphasize the first cooling time: Cooling time refers to the time from when the molten plastic is injected into the mold to when it is completely cooled and solidified and can be safely demolded. Usually, the holding time is part of the cooling time, that is, the holding time occurs in the early stage of the cooling process. When the holding time ends, the remaining cooling time is mainly used to ensure that the plastic is completely solidified.
[0066] In the present invention, the holding time is separated from the cooling time, that is, the "holding time" is not a part of the "first cooling time", but "after the holding time ends" (that is, the first holding time is completed), it is determined to enter cooling (that is, start entering the first cooling time).
[0067] In the present invention, the holding time is separated from the cooling time, and the stages where the holding time ends and the cooling starts are clearly distinguished, so that the time of each stage can be controlled more accurately. The time setting of each stage can be optimized according to the specific material properties and product requirements, thereby improving product quality. By independently managing the two processes of holding and cooling, the process parameters can be adjusted more flexibly. Treating holding and cooling as independent steps is conducive to better recording and analyzing data in the production process, which is conducive to subsequent quality control, troubleshooting and process improvement. By fine-tuning the holding and cooling stages, energy consumption can be reduced while ensuring product quality.
[0068] S12, judging whether there is a need to obtain the quality data of the plastic cups produced in the current batch in the target plastic cup production line according to the production efficiency per the first unit time, if so, obtain it, if not, re-execute step S11, wherein the quality data includes the wall thickness uniformity, dimensional deviation rate, compression resistance rate, appearance defect rate, sealing rate, pattern consistency rate, high temperature resistance rate, and the number of plastic cups produced in the current batch is at least 2.
[0069] Specifically, if the production efficiency per unit time is greater than a preset production efficiency threshold, there is a need to obtain quality data of the plastic cups produced in the current batch of the target plastic cup production line; if the production efficiency per unit time is less than or equal to the preset production efficiency threshold, step S11 is re-executed.
[0070] The preset production efficiency threshold can be determined based on the actual situation of the plastic cup production line, which will not be elaborated here. When the production efficiency per unit time is greater than the preset production efficiency threshold, it means that the plastic cups are produced too fast. Excessive production speed may have a negative impact on the quality of the plastic cups and the overall efficiency of the production line. The direct cause of excessive production may be too fast filling speed, insufficient holding time, or insufficient cooling time.
[0071] If the filling speed is too fast, it may lead to insufficient filling, which may introduce more air or bubbles. Too fast a filling speed may cause excessive injection pressure, increase mold wear, and may cause overflow (flash), affecting the appearance and dimensional accuracy of the product. Insufficient holding time may lead to incomplete filling or stress concentration. Insufficient cooling time may lead to thermal stress and warping, insufficient strength, and poor dimensional stability.
[0072] The present invention can reflect whether there are problems such as insufficient holding time, insufficient cooling time, and excessive filling speed by relying only on preset production efficiency thresholds, thereby avoiding the need to separately obtain parameters such as holding time, cooling time, filling speed, and the tediousness of designing judgment logic in sequence, thereby improving production line management efficiency.
[0073] If the production efficiency per unit time is less than or equal to the preset production efficiency threshold, it means that the production speed is reasonable and step S11 can be executed again.
[0074] Explanation of quality data:
[0075] Wall thickness uniformity: the ratio of the number of plastic cups with uniform wall thickness in the current batch of plastic cups produced to the number of all plastic cups produced;
[0076] Size deviation rate: the ratio of the number of plastic cups whose actual size does not differ from the designed size in the current batch of plastic cups produced to the number of all plastic cups produced;
[0077] Compression resistance rate: the ratio of the number of plastic cups that can withstand the preset pressure in the current batch of plastic cups produced to the number of all plastic cups produced;
[0078] Appearance defect rate: the ratio of the number of plastic cups without bubbles or dents in the current batch of plastic cups produced to the number of all plastic cups produced. The appearance defect rate is determined by:
[0079]
[0080] Among them, P is the appearance defect rate of the plastic cups produced in the current batch, g q is the number of plastic cups produced in the current batch that do not contain bubbles or dents, and Z is the total number of plastic cups produced in the current batch.
[0081] Sealing rate: the ratio of the number of plastic cups without leakage in the current batch of plastic cups produced to the number of all plastic cups produced;
[0082] Pattern consistency rate: the ratio of the number of plastic cups with the same actual pattern as the designed pattern in the current batch of plastic cups produced to the number of all plastic cups produced;
[0083] High temperature resistance rate: the ratio of the number of plastic cups in the current batch that can remain deformed at the preset temperature to the number of all plastic cups produced.
[0084] S13, updating the first filling flow rate in the first operating parameter according to the wall thickness uniformity, appearance defect rate, pattern consistency rate and the first filling flow rate in the quality data to obtain a second filling flow rate.
[0085] Specifically include:
[0086] F 2 =αF 1 ×t×w×h
[0087] Among them, F2 is the second filling flow, α is the preset adjustment coefficient, F 1 is the first filling flow rate, h is the wall thickness uniformity, t is the pattern consistency rate, w is the appearance defect rate, and the preset adjustment coefficient α can be determined according to relevant experience or actual conditions, and α is less than or equal to 1.
[0088] The present invention can realize precise adjustment of the second filling flow rate by dynamically monitoring and comprehensively analyzing the wall thickness uniformity, appearance defect rate and pattern consistency rate, thereby optimizing the overall production efficiency and product quality while ensuring the consistency of the wall thickness of the plastic cup, reducing surface defects and maintaining the high quality of the decorative pattern.
[0089] In the production of plastic cups, the filling flow rate determines the speed at which the molten plastic enters the mold. If the filling speed is too fast, the plastic in some areas may not fully fill the details of the mold, affecting the uniformity of the wall thickness; too fast a filling speed will introduce more air or gas, and the gas will be trapped inside the plastic, forming bubbles or voids, causing appearance defects; filling speed is too fast, which may weaken the adhesion between the decorative layer (such as coating or film) and the plastic substrate, resulting in inconsistent patterns.
[0090] S14, according to the wall thickness uniformity, dimensional deviation rate, compression resistance rate, appearance defect rate, sealing rate and the first pressure holding time in the quality data, the first pressure holding time in the first operating parameter is updated to obtain a second pressure holding time.
[0091] Specifically include:
[0092]
[0093] Among them, h is the wall thickness uniformity, c is the dimensional deviation rate, 7 is the compressive strength rate, w is the appearance defect rate, k is a positive number that is infinitely close to 0, m is the sealing rate, β is the preset adjustment coefficient, and B 1 is the first pressure holding time, B 2 is the second holding pressure time. The preset adjustment coefficient β can be determined according to relevant experience or actual conditions. β is less than or equal to 1. It can be understood that when hycmw is 0, it is also possible to directly detect whether the production equipment is faulty.
[0094] When determining the second holding time, the square root function is used to smooth the final adjustment coefficient to prevent excessive fluctuations in the holding time due to extreme changes, thereby maintaining the stability and controllability of production.
[0095] The present invention can accurately adjust the pressure holding time by dynamically monitoring and comprehensively analyzing the wall thickness uniformity rate, dimensional deviation rate, compression resistance rate, appearance defect rate and sealing rate, thereby optimizing the overall production process while ensuring the structural strength, dimensional accuracy, surface quality and functionality of the plastic cup, improving the consistency of product quality and production efficiency, and achieving a more stable and efficient production process.
[0096] In the production of plastic cups, the main function of holding pressure is to ensure that the molten plastic is completely filled in the mold. If the holding time is insufficient, it will affect the uniformity of the wall thickness. The holding time directly affects the degree of solidification of the plastic in the mold. Insufficient holding time may cause the plastic to be demolded before it is completely solidified, which will cause dimensional changes and affect the dimensional deviation rate. The compression resistance rate reflects the ability of the plastic cup to withstand pressure. The holding stage not only helps fill the mold, but also makes the plastic molecular chains more tightly arranged by applying pressure, thereby enhancing the mechanical strength of the material. In other words, the holding time will affect the compression resistance rate. The holding time affects the flow and solidification process of the plastic in the mold. If the holding time is insufficient, surface defects such as bubbles, flash, and uneven color may appear, affecting the appearance defect rate. The holding stage affects the uniform filling and close contact of the plastic in the mold, that is, it affects the sealing rate.
[0097] S15, updating the first cooling time in the first operating parameter according to the dimensional deviation rate, the pressure resistance rate, the sealing rate, the high temperature resistance rate and the first cooling time in the quality data to obtain a second cooling time.
[0098] Specifically include:
[0099]
[0100] Among them, c is the dimensional deviation rate, y is the compression resistance rate, m is the sealing rate, n is the high temperature resistance rate, k is a positive number that is infinitely close to 0, and L 1 is the first cooling time, L 2 is the second cooling time, γ is a preset adjustment coefficient, γ is less than or equal to 1. It can be understood that when ycmn is 0, it is also possible to detect whether the production equipment is faulty.
[0101] When determining the second cooling time, the square root function is used to smooth the final adjustment coefficient to prevent excessive fluctuations in the holding time due to extreme changes, thereby maintaining the stability and controllability of production.
[0102] The present invention can accurately adjust the cooling time by dynamically monitoring and comprehensively analyzing the dimensional deviation rate, pressure resistance rate, sealing rate and high temperature resistance rate, thereby optimizing the overall production process while ensuring the dimensional accuracy, mechanical strength, sealing performance and thermal stability of the plastic cup, improving the consistency of product quality and production efficiency, and ultimately achieving a more stable and efficient production process.
[0103] The cooling time determines the transformation process of the plastic from the molten state to the solid state. If the cooling time is insufficient, the plastic may not be fully solidified before demolding, resulting in dimensional instability and affecting the dimensional deviation rate. The cooling time affects the arrangement and crystallinity of the plastic molecular chain, in other words, it affects the compression resistance rate. The cooling time affects the molding quality of the sealing part, that is, it affects the sealing rate. The cooling time affects the stability and crystallinity of the plastic molecular chain, that is, it affects the high temperature resistance rate.
[0104] S16, constructing a second operating parameter according to the second filling flow, the second holding time and the second cooling time, and judging whether to control the target plastic cup production line to operate with the second operating parameter according to a preset threshold value corresponding to the second operating parameter; if so, controlling the target plastic cup production line to operate with the second operating parameter, and if not, sending an alarm signal to the target user terminal.
[0105] Specifically, it includes: judging whether the second filling flow in the second operating parameter is lower than the preset flow threshold; if the second filling flow is lower than the preset flow threshold, sending an alarm signal to the target user terminal; if the second filling flow is not lower than the preset flow threshold, judging whether the second pressure holding time in the second operating parameter is higher than the preset pressure holding threshold; if the second pressure holding time is higher than the preset pressure holding threshold, sending an alarm signal to the target user terminal; if the second pressure holding time is not higher than the preset pressure holding threshold, judging whether the second cooling time in the second operating parameter is higher than the preset cooling threshold; if the second cooling time is higher than the preset cooling threshold, sending an alarm signal to the target user terminal; if the second cooling time is not higher than the preset cooling threshold, controlling the target plastic cup production line to operate with the second operating parameter.
[0106] If the second filling flow rate is lower than the preset flow rate threshold, it means that the second filling flow rate is lower than the lowest filling speed threshold, and a too slow filling flow rate will lead to material shortage (the second filling flow rate should be lower than the first filling flow rate and higher than the preset flow rate threshold). If the second filling flow rate is lower than the preset flow rate threshold, it means that the second filling flow rate is unreasonable, and an alarm signal can be sent to the target user terminal.
[0107] If the second pressure-holding time is higher than the preset pressure-holding threshold, it means that the second pressure-holding time is too long, which may cause the plastic molecular chains to be arranged too closely, resulting in a decrease in surface smoothness and an "orange peel" effect (the second pressure-holding time should be longer than the first pressure-holding time and shorter than the preset pressure-holding threshold). If the second pressure-holding time is higher than the preset pressure-holding threshold, it means that the second pressure-holding time is unreasonable, and an alarm signal can be sent to the target user terminal.
[0108] If the second cooling time is higher than the preset cooling threshold, it means that the second cooling time is too long. Excessive cooling may cause large fluctuations in the mold temperature and accelerate the aging and wear of the mold (the second cooling time should be longer than the first cooling time and shorter than the preset cooling threshold). If the second cooling time is higher than the preset cooling threshold, it means that the second cooling time is unreasonable, and an alarm signal can be sent to the target user terminal.
[0109] The present invention realizes step-by-step judgment by using preset flow threshold, preset pressure holding threshold and preset cooling threshold. Step-by-step judgment realizes continuous monitoring of the production process, ensures operation within the optimal parameter range, avoids the complexity of simultaneous judgment of multiple parameters, and thus improves overall production efficiency; it can ensure high-quality product output, and at the same time enhances the stability and reliability of the production line through timely early warning and correction mechanisms, thereby realizing intelligent production.
[0110] In summary, the present invention can intelligently adjust the pressure holding time, filling flow rate and cooling time according to the quality inspection results of plastic cups produced in different batches, so that the adjusted pressure holding time, filling flow rate and cooling time are more in line with the production of the batch of materials, thereby improving the production quality.
[0111] In the present invention, the holding time is separated from the cooling time, and the stages where the holding time ends and the cooling starts are clearly distinguished, so that the time of each stage can be controlled more accurately. The time setting of each stage can be optimized according to the specific material properties and product requirements, thereby improving product quality. By independently managing the two processes of holding and cooling, the process parameters can be adjusted more flexibly. Treating holding and cooling as independent steps is conducive to better recording and analyzing data in the production process, which is conducive to subsequent quality control, troubleshooting and process improvement. By fine-tuning the holding and cooling stages, energy consumption can be reduced while ensuring product quality.
[0112] The present invention can reflect whether there are problems such as insufficient holding time, insufficient cooling time, and excessive filling speed by relying only on preset production efficiency thresholds, thereby avoiding the need to separately obtain parameters such as holding time, cooling time, filling speed, and the tediousness of designing judgment logic in sequence, thereby improving production line management efficiency.
[0113] The present invention can realize precise adjustment of the second filling flow rate by dynamically monitoring and comprehensively analyzing the wall thickness uniformity, appearance defect rate and pattern consistency rate, thereby optimizing the overall production efficiency and product quality while ensuring the consistency of the wall thickness of the plastic cup, reducing surface defects and maintaining the high quality of the decorative pattern.
[0114] When determining the second holding time and the second cooling time, the square root function is used to smooth the final adjustment coefficient to prevent excessive fluctuations in the holding time due to extreme changes, thereby maintaining the stability and controllability of production.
[0115] The present invention can accurately adjust the pressure holding time by dynamically monitoring and comprehensively analyzing the wall thickness uniformity rate, dimensional deviation rate, compression resistance rate, appearance defect rate and sealing rate, thereby optimizing the overall production process while ensuring the structural strength, dimensional accuracy, surface quality and functionality of the plastic cup, improving the consistency of product quality and production efficiency, and achieving a more stable and efficient production process.
[0116] The present invention can accurately adjust the cooling time by dynamically monitoring and comprehensively analyzing the dimensional deviation rate, pressure resistance rate, sealing rate and high temperature resistance rate, thereby optimizing the overall production process while ensuring the dimensional accuracy, mechanical strength, sealing performance and thermal stability of the plastic cup, improving the consistency of product quality and production efficiency, and ultimately achieving a more stable and efficient production process.
[0117] The present invention realizes step-by-step judgment by using preset flow threshold, preset pressure holding threshold and preset cooling threshold. Step-by-step judgment realizes continuous monitoring of the production process, ensures operation within the optimal parameter range, avoids the complexity of simultaneous judgment of multiple parameters, and thus improves overall production efficiency; it can ensure high-quality product output, and at the same time enhances the stability and reliability of the production line through timely early warning and correction mechanisms, thereby realizing intelligent production.
