Description

Technical Field

[0001] This invention relates to the field of aluminum can cleaning machine technology, specifically a cleaning agent addition control method and system for an aluminum can cleaning machine. Background Technology

[0002] In the industrial production process of aluminum beverage cans, the cleaning process is a core step in ensuring product quality and the stability of subsequent processing. During processing, aluminum beverage cans become contaminated with lubricating oil, rolling oil, aluminum ash, and oxide scale. If these contaminants are not thoroughly removed, they will not only affect the adhesion of subsequent processes such as spraying and printing, but may also remain on the inner wall of the can, posing potential quality risks. Therefore, they must be completely removed through professional cleaning processes, and the industry currently widely uses cleaning machines to complete this cleaning operation. However, in the actual operation of cleaning machines, most rely on workers' past experience to manually add a precise amount of cleaning agent to the cleaning tank. This experience-based operation mode is easily affected by factors such as human judgment bias and fluctuations in operating conditions, which can easily lead to inaccurate addition of cleaning agent, thus affecting the production quality of the aluminum beverage cans. Summary of the Invention

[0012] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0013] A method for controlling the addition of cleaning agent in an aluminum can cleaning machine, comprising the following steps: Step S1: Set the cleaning agent concentration threshold for the aluminum can cleaning machine; Step S2: Determine if the detection electrode of the aluminum can cleaning machine is operating normally. If it is operating normally, collect the real-time concentration of the cleaning agent and determine if the real-time concentration is lower than the cleaning agent concentration threshold. If so, calculate the cleaning agent addition amount based on the cleaning agent consumption corresponding to the preset target production speed of aluminum cans, and execute the automatic cleaning agent addition operation according to the cleaning agent addition amount. If not, stop the cleaning agent addition operation. If the machine malfunctions, calculate the cleaning agent addition amount based on the target production quantity or target production time of aluminum cans, and the preset cleaning agent consumption per unit quantity or unit time of aluminum cans, and execute the automatic cleaning agent addition operation according to the cleaning agent addition amount.

[0014] This solution provides a method for controlling the addition of cleaning agents in an aluminum can cleaning machine, such as... Figure 1As shown, the first step is to set the cleaning agent concentration threshold for the aluminum can cleaning machine. In this embodiment, the aluminum can cleaning machine includes an acid pickling tank and a phosphating tank. The acid pickling tank uses sulfuric acid stored inside to acidify the surface of the cans, effectively removing stubborn contaminants such as residual aluminum ash and oxide scale from rolling. The phosphating tank uses an internal phosphating agent to form a uniform phosphating film on the surface of the cans, providing a good adhesion base for subsequent spraying and printing processes. By setting corresponding concentration thresholds for the sulfuric acid in the acid pickling tank and the phosphating agent in the phosphating tank, it is ensured that the need for adding sulfuric acid or the amount of phosphating agent can be accurately determined based on the real-time comparison of the concentration with the threshold, thereby ensuring the treatment effect of the two key processes of acid pickling and phosphating. The second step is to determine whether the detection electrodes of the aluminum can cleaning machine are operating normally. If they are operating normally, the real-time concentration of the cleaning agent in the aluminum can cleaning machine is collected, and it is determined whether the real-time concentration of the cleaning agent is lower than the cleaning agent concentration threshold. If so, the cleaning agent addition amount is calculated based on the cleaning agent consumption corresponding to the preset target production speed of aluminum cans, and the automatic cleaning agent addition operation is executed according to the cleaning agent addition amount. If not, the cleaning agent addition operation is stopped. If the machine malfunctions, the cleaning agent addition amount is calculated based on the target production quantity or target production time of aluminum cans, and the preset cleaning agent consumption per unit quantity or unit time of aluminum cans, and the automatic cleaning agent addition operation is executed according to the cleaning agent addition amount. In this embodiment, by setting corresponding immersion detection electrodes in the pickling tank and the phosphating tank respectively, the real-time detection of the concentration of sulfuric acid solution in the pickling tank and the phosphating agent in the phosphating tank can be realized. When cleaning agent needs to be added, the system prioritizes a cleaning agent addition mode based on the cleaning agent concentration and the target production speed of aluminum cans. Specifically, this mode compares the real-time concentration of sulfuric acid in the pickling tank or phosphating agent in the phosphating tank with a corresponding concentration threshold. If the real-time concentration of sulfuric acid or phosphating agent is lower than the threshold, the amount of sulfuric acid or phosphating agent consumed at the target production speed is used as the addition amount, and the addition operation is executed automatically. For example, if the target production speed of the aluminum can production line is 3500 cans / minute, and the pre-set consumption of sulfuric acid or phosphating agent at this target speed is 3L, then the addition amount is set to 3L. This mode avoids over- or under-dosing due to simply adding based on concentration, while matching actual production needs. When the real-time concentration of sulfuric acid solution in the pickling tank or phosphating agent in the phosphating tank exceeds the corresponding concentration threshold, it indicates that the current concentration of sulfuric acid solution in the pickling tank or phosphating agent in the phosphating tank does not meet the cleaning requirements. Therefore, the cleaning agent addition operation should be stopped immediately to prevent the concentration from being too high, which could affect the cleaning effect or cause waste of raw materials.If the immersion detection electrode malfunctions and causes concentration detection to fail, in order to ensure the continuous production of aluminum cans, the system will switch to a counting or timing-based addition mode. This involves multiplying the target production quantity of aluminum cans by the preset consumption of sulfuric acid or phosphating agent per unit quantity of aluminum cans, or multiplying the target production time of aluminum cans by the preset consumption of sulfuric acid or phosphating agent per unit time of aluminum cans. This allows for accurate calculation of the amount of sulfuric acid or phosphating agent to be added and automatic addition.

[0015] This solution sets a cleaning agent concentration threshold for the aluminum can cleaning machine and monitors the operation of its detection electrodes. When the electrodes are functioning normally, it checks if the real-time cleaning agent concentration collected by the electrodes is below the threshold. If so, it calculates the cleaning agent addition amount based on the preset cleaning agent consumption at the target production speed of the aluminum cans and automatically performs the addition operation. If not, it does not perform the addition operation. When the detection electrodes malfunction, it calculates the cleaning agent addition amount based on the target production quantity or target production time of the aluminum cans, as well as the preset cleaning agent consumption per unit quantity or unit time of aluminum cans, and automatically performs the addition operation. Compared to the traditional cleaning agent addition method that relies on manual experience, this solution uses an automated cleaning agent addition method, preventing inaccurate cleaning agent addition due to human factors, thereby effectively improving the production quality of aluminum cans.

[0016] Preferably, the method further includes the following steps: setting a first cleaning agent contamination threshold and a second cleaning agent contamination threshold for the aluminum can cleaning machine; collecting the real-time contamination level of the cleaning agent based on the detection electrodes of the aluminum can cleaning machine, and determining whether the real-time contamination level of the cleaning agent is greater than the first cleaning agent contamination threshold; if not, calculating the cleaning agent addition amount based on the cleaning agent consumption corresponding to the preset target production speed of the aluminum cans, and performing an automatic cleaning agent addition operation based on the cleaning agent addition amount; if yes, determining whether the real-time contamination level of the cleaning agent is less than the second cleaning agent contamination threshold; if yes, triggering an alarm signal, adjusting the cleaning agent addition amount calculation strategy, and performing an automatic cleaning agent addition operation based on the adjusted cleaning agent addition amount; if no, stopping the cleaning agent addition operation.

[0017] In this embodiment, the cleaning agent contamination level of the aluminum can cleaning machine refers to the total mass of aluminum elements generated after the surface material of the aluminum can is dissolved by the cleaning agent during the cleaning process, contained in a unit volume of cleaning agent. The first cleaning agent contamination threshold is set to 45 g / L, and the second cleaning agent contamination threshold is set to 50 g / L. By using both thresholds, the contamination status of the cleaning agent can be monitored in real time. When the real-time contamination level of the cleaning agent does not exceed the first threshold, the cleaning agent is added precisely according to production needs, ensuring the stability of the aluminum can cleaning effect. When the real-time contamination level of the cleaning agent is between the first and second thresholds, an alarm signal is triggered to promptly alert staff to investigate the cause of accumulated cleaning agent contamination. By adjusting the cleaning agent addition calculation strategy, excessive injection of cleaning agent can be avoided while ensuring the cleaning effect of the aluminum cans. When the real-time contamination level of the cleaning agent exceeds the second contamination threshold, stop adding the cleaning agent in time to avoid substandard cleaning caused by using ineffective cleaning agent, thereby ensuring the surface treatment quality of aluminum cans.

[0018] To further explain, the adjustment strategy for calculating the cleaning agent addition amount is as follows: First, multiply the target production quantity of aluminum cans by the preset cleaning agent consumption per unit quantity of aluminum cans to obtain the first cleaning agent addition amount. Then, multiply the target production time of aluminum cans by the preset cleaning agent consumption per unit time of aluminum cans to obtain the second cleaning agent addition amount. Next, calculate the average of the first and second cleaning agent addition amounts. Then, calculate the average of the first and second cleaning agent contamination thresholds. Finally, determine whether the real-time contamination level of the cleaning agent is less than the average of the first and second cleaning agent contamination thresholds. If so, it indicates that the contamination level of the cleaning agent is too low, and the amount is reduced by 2% based on the average of the first and second cleaning agent addition amounts. If so, it indicates that the contamination level of the cleaning agent is too high, and the amount is reduced by 4% based on the average of the first and second cleaning agent addition amounts to obtain the adjusted cleaning agent addition amount.

[0019] Preferably, the method further includes the following steps: constructing a database; storing the real-time concentration and real-time contamination of the cleaning agent collected by the detection electrode based on the aluminum can cleaning machine in the database; and generating a visual analysis chart based on the real-time concentration and real-time contamination of the cleaning agent in the database, combined with the data time dimension or production correlation dimension.

[0020] In this embodiment, by collecting real-time concentration and contamination levels of the cleaning agent using the detection electrodes of the aluminum can cleaning machine and storing them in a database, it is beneficial to store and manage the cleaning agent parameters. By combining the real-time concentration and contamination levels of the cleaning agent in the database with time dimensions (e.g., hours, days, or weeks) or production-related dimensions (e.g., production batches or total production volume of aluminum cans), visual analysis charts, such as trend graphs, can be generated. This allows for a clearer and more intuitive presentation of the dynamic changes in the cleaning agent parameters, providing data support for staff to understand the cleaning agent status and optimize cleaning strategies.

[0021] Another aspect of this application provides a cleaning agent addition control system for an aluminum can cleaning machine, the system comprising: The first setting module is used to set the cleaning agent concentration threshold of the aluminum can cleaning machine; The first judgment module is used to determine whether the detection electrode of the aluminum can cleaning machine is operating normally. If it is operating normally, the first acquisition module is executed and the second judgment module is executed; if it is malfunctioning, the second calculation module is executed and the first add operation execution module is executed. The first data acquisition module is used to collect the real-time concentration of the cleaning agent in the aluminum can cleaning machine; The second judgment module is used to determine whether the real-time concentration of the cleaning agent is lower than the cleaning agent concentration threshold. If it is, the first calculation module is executed, and the first addition operation execution module is executed; if not, the first addition operation execution module is not executed. The first calculation module is used to calculate the amount of cleaning agent to be added based on the cleaning agent consumption corresponding to the preset target production speed of aluminum cans. The second calculation module is used to calculate the amount of cleaning agent to be added based on the target production quantity or target production time of aluminum cans and the preset cleaning agent consumption per unit quantity or unit time of aluminum cans. The first addition operation execution module is used to perform automatic addition of cleaning agent based on the amount of cleaning agent added.

[0022] This solution provides a cleaning agent addition control system for an aluminum can cleaning machine. Through the coordinated operation of a first setting module, a first judgment module, a first data acquisition module, a second judgment module, a first calculation module, a second calculation module, and a first addition operation execution module, it achieves automated cleaning agent addition control. Compared to traditional cleaning agent addition methods that rely on manual experience, this solution prevents inaccurate cleaning agent dosage due to human error, thereby effectively improving the production quality of aluminum cans.

[0023] Preferably, the device further includes: a second setting module for setting a first cleaning agent contamination threshold and a second cleaning agent contamination threshold for the aluminum can cleaning machine; a second acquisition module for acquiring the real-time contamination level of the cleaning agent based on the detection electrodes of the aluminum can cleaning machine, and executing a third judgment module; a third judgment module for judging whether the real-time contamination level of the cleaning agent is greater than the first cleaning agent contamination threshold; if not, executing a first calculation module and executing a first addition operation execution module; if yes, executing a fourth judgment module; a fourth judgment module for judging whether the real-time contamination level of the cleaning agent is less than the second cleaning agent contamination threshold; if yes, executing an alarm triggering module, executing a strategy adjustment module, and executing a second addition operation execution module; if not, not executing the second addition operation execution module; an alarm triggering module for triggering an alarm signal; a strategy adjustment module for adjusting the cleaning agent addition calculation strategy; and a second addition operation execution module for executing an automatic cleaning agent addition operation according to the adjusted cleaning agent addition amount.

[0024] In this embodiment, a second setting module is provided to offer a benchmark for the dual determination of cleaning agent contamination levels. In the third determination module, when the real-time contamination level of the cleaning agent is less than the first cleaning agent contamination threshold, the execution of the first calculation module and the first addition operation execution module ensures the stability of the aluminum can cleaning effect. When the real-time contamination level of the cleaning agent is greater than the first cleaning agent contamination threshold, a fourth determination module is executed. In the fourth determination module, when the real-time contamination level of the cleaning agent is less than the second cleaning agent contamination threshold, the execution of the alarm trigger module promptly alerts staff to investigate the cause of accumulated cleaning agent contamination; the execution of the strategy adjustment module and the second addition operation execution module prevents excessive injection of cleaning agent while ensuring the cleaning effect of the aluminum can. When the real-time contamination level of the cleaning agent is greater than the second cleaning agent contamination threshold, the second addition operation execution module is not executed to avoid substandard cleaning caused by the use of ineffective cleaning agent, thereby ensuring the surface treatment quality of the aluminum can.

[0025] Preferably, the system further includes: a construction module for building a database; a storage module for storing the real-time concentration and contamination level of the cleaning agent collected by the detection electrodes of the aluminum can cleaning machine in the database; and a chart generation module for generating visual analysis charts based on the real-time concentration and contamination level of the cleaning agent in the database, combined with the data's time dimension or production-related dimension. In this embodiment, the storage module facilitates the storage and management of cleaning agent parameters.
