Description

Technical Field

[0001] This application relates to the field of production line control technology, and in particular to a method and system for adjusting process parameters of carbon powder mixing. Background Technology

[0002] Due to their uneven particle size and shape, toner particles are typical polydisperse powders. The toner mixing process involves thoroughly and uniformly mixing and melting various raw materials (mainly resins, pigments / dyes, charge control agents, waxes, etc.) to form a homogeneous mixture with the required electrical, physical, and developing properties, laying the foundation for subsequent pulverization, grading, and surface treatment.

[0063] Figure 1 This is a schematic flowchart of a method for controlling process parameters in carbon powder mixing according to an embodiment of this application. Detailed Implementation

[0064] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0065] This application proposes a method for controlling process parameters in toner mixing, applicable to a toner mixing production line. The production line includes a control terminal, and the method is applicable to the control terminal. Optionally, it may also include equipment such as a screw conveyor and a feeding mechanism. The method proposed in this application is applicable to the control terminal, which can be an industrial server, a PC (personal computer), etc., and is not limited here. Please refer to [link to relevant documentation]. Figure 1 The method proposed in this application includes the following steps:

[0066] S101: Obtain the product to be tested from the product end of the toner mixing production line and place the product to be tested in the testing equipment. The testing equipment includes a testing cavity of a cube, an ultrasonic generator set on one side of the testing cavity, and an ultrasonic sensor set opposite to the ultrasonic generator. The product to be tested is placed and piled in the testing cavity, and the height direction of the testing cavity is parallel to the direction of gravity.

[0067] Understandably, in this embodiment, detection and production form a closed-loop control. Therefore, it is necessary to obtain the specific parameters of the product from the product generation end. During the toner production process, toner particle dispersibility is a key data point among toner production indicators. Conventional detection generally uses traditional microscopes for manual inspection, while obtaining the results using a high-cost laser particle size analyzer is preferable. Manual inspection has poor timeliness, while laser detectors are also expensive.

[0068] In this embodiment, the detection equipment is integrated into the production line. After the product is output from the production line, it can be automatically extracted from the line and placed into the detection equipment. Specifically, the product to be detected is placed and piled up in the detection chamber, with the height of the chamber parallel to the direction of gravity. Simultaneously, detection data can be acquired through an ultrasonic generator positioned on one side of the detection chamber and an ultrasonic sensor positioned opposite it. It should be noted that in this embodiment, the amount of product to be detected acquired each time can be quantitative, for example, filling the entire detection chamber. In this embodiment, the pile height of the product to be detected within the detection chamber is necessarily higher than that of the ultrasonic generator and ultrasonic sensor. The transmitter and sensor are positioned opposite each other, directly measuring penetration attenuation, which is more accurate than reflective methods.

[0069] S102: Apply vibration to the detection cavity for a first unit time based on the first vibration frequency, and obtain the first ultrasonic attenuation rate based on the ultrasonic sensor.

[0070] Understandably, in this embodiment, after the product to be detected has accumulated in the detection chamber, the detection chamber can be vibrated for the first unit of time. Since the height direction of the detection chamber is parallel to the direction of gravity at this time, the product to be detected, under the action of gravity, causes the toner to settle naturally. That is, the toner particles form aggregates of different sizes due to their different degrees of aggregation. Based on Stokes' law, larger particles settle faster and accumulate at the bottom of the chamber, while smaller particles / agglomerates are suspended in the upper part due to Brownian motion. In other words, the toner particles undergo stratification within the detection chamber.

[0071] Understandably, the ultrasonic sensor and ultrasonic generator are positioned perpendicular to the direction of gravity. Therefore, the sound wave transmission path between the ultrasonic sensor and the ultrasonic generator is also parallel to the layering plane of the carbon powder particles. The sound wave transmission attenuation is relatively uniform. At this point, the first ultrasonic attenuation rate can be obtained based on the ultrasonic sensor.

[0072] In some implementations, prior to detection, a second vibration time can be applied to the detection cavity based on a second vibration frequency. It is understood that the purpose of the second vibration frequency is to make the product to be detected fit the detection cavity more closely; therefore, the second vibration frequency is lower than the first vibration frequency, and the second unit time is shorter than the first unit time, reducing the delamination phenomenon of the product to be detected when the second vibration frequency is generated.

[0073] S103: Flip the detection chamber so that the height direction of the detection chamber is perpendicular to the direction of gravity.

[0074] Understandably, in this embodiment, after the detection cavity is flipped, the height direction of the detection cavity is perpendicular to the direction of gravity. Therefore, the ultrasonic sensor and the ultrasonic generator are detached from the detection unit. At this time, the sound wave transmission line between the ultrasonic sensor and the ultrasonic generator is perpendicular to the layering plane of the carbon powder particles.

[0075] In some implementations, in order to ensure the fit after flipping, a second unit time of vibration can be applied to the detection cavity based on a second vibration frequency.

[0076] S104: Obtain the second ultrasonic attenuation rate based on the ultrasonic sensor, and obtain the toner particle distribution index based on the first ultrasonic attenuation rate and the second ultrasonic attenuation rate.

[0077] Understandably, because the product under test exhibited stratification under the first vibration frequency, the aggregation of carbon powder particles of the same size resulted in a clear interface in the ultrasonic testing results. Furthermore, the aggregation of carbon powder particles of the same size increased the blocking effect on sound waves smaller than the particles, meaning the agglomeration led to enhanced sound wave scattering. Therefore, the second ultrasonic attenuation rate would be significantly lower than the first ultrasonic attenuation rate. In other words, the more pronounced the stratification, the greater the impact on the attenuation of ultrasonic transmission.

[0078] Since the degree of aggregation of toner particles directly affects the stratification, and the stratification directly affects the attenuation of ultrasonic transmission, an expression relating ultrasonic attenuation to the degree of aggregation of toner particles can be established.

[0079] For example, in this embodiment, the relationship between ultrasonic attenuation and toner particle aggregation can be characterized using machine learning. Specifically, in this embodiment, an artificial intelligence model of ultrasonic attenuation rate-toner distribution index can be established, and the artificial intelligence model can be trained based on historical experimental data. The historical data can be obtained through historical experiments. The trained ultrasonic attenuation rate-toner distribution index artificial intelligence model is then acquired, and the first ultrasonic attenuation rate and the second ultrasonic attenuation rate are imported into the artificial intelligence model. Based on the output of the artificial intelligence model, the toner particle distribution index is obtained.

[0080] In other embodiments, other methods may be used, such as mathematical calculations, which are not limited here.

[0081] S105: Adjust the production line based on the toner distribution index.

[0082] Understandably, the control method in this embodiment can also employ artificial intelligence. Specifically, a toner mixing process parameter model can be established. This model includes mixing temperature, mixing time, screw speed, feed rate, toner-to-additive ratio, and toner particle distribution index. The model is trained based on historical production data. Then, the correlation between mixing temperature, mixing time, screw speed, feed rate, toner-to-additive ratio, and toner particle distribution index is obtained. Before the toner mixing process begins, the target toner particle distribution index requirement is obtained and input into the toner mixing process parameter model. Based on the model's output, the target mixing temperature, target mixing time, target screw speed, target feed rate, and target toner-to-additive ratio are obtained. Finally, based on the model's output, the current mixing temperature, current mixing time, current screw speed, current feed rate, and current toner-to-additive ratio are dynamically adjusted.

[0083] Optionally, in this embodiment, the first ultrasonic attenuation rate and the second ultrasonic attenuation rate are obtained, and the first ultrasonic attenuation rate and the second ultrasonic attenuation rate are compared with the target ultrasonic attenuation rate. If the first ultrasonic attenuation rate and the second ultrasonic attenuation rate are greater than the target ultrasonic attenuation rate, it can be determined that the main influencing factor of the particles is that the particles are too fine or agglomerated. At this time, the target screw speed and the target feed speed are preferentially controlled during the control process.

[0084] This application proposes a method for controlling process parameters in toner mixing. First, a product to be tested is obtained from the product end of the toner mixing production line and placed in a testing device. The testing device includes a cube-shaped testing cavity, an ultrasonic generator disposed on one side of the testing cavity, and an ultrasonic sensor disposed opposite to the ultrasonic generator. Then, vibration is applied to the testing cavity at a first vibration frequency for a first unit time, and a first ultrasonic attenuation rate is obtained based on the ultrasonic sensor. Next, the testing cavity is flipped so that its height direction is perpendicular to the direction of gravity. Then, a second ultrasonic attenuation rate is obtained based on the ultrasonic sensor, and a toner particle distribution index is obtained based on the first and second ultrasonic attenuation rates. Finally, the production line is controlled based on the toner distribution index. This method for controlling process parameters in toner mixing utilizes the difference in ultrasonic attenuation under changing gravity to evaluate toner particle dispersion. It is faster than manual microscopy and eliminates the need for a laser detector, thus saving production costs.

Based on the output of the toner mixing process parameter model, the target mixing temperature, target mixing time, target screw speed, target feed rate, and target toner to additive ratio are obtained.
