Description

Technical Field

[0001] This application relates to the technical field of feed spraying, and in particular to a nozzle structure control method and system for a micro-liquid continuous spraying device. Background Technology

[0002] A micro-liquid continuous spraying device is a device used to continuously and proportionally add multiple liquid components to feed after pelleting. It consists of multiple spray nozzles, storage devices for storing different liquid components, and metering pumps that provide liquid transport power for the liquid components.

[0003] In related technologies, a multi-liquid online post-coating system refers to a control system used to continuously and proportionally add multiple liquid components to feed after pelleting. The multi-liquid online post-coating system can convert liquid components into uniform micro-droplets and can strictly control the coating amount and coating uniformity during feed processing as required.

[0004] Regarding the aforementioned technologies, on the one hand, when the liquid component sprayed onto the feed is an easily deactivated component, the temperature of the easily deactivated liquid component deviates from the corresponding suitable active temperature range due to the influence of the liquid flow rate and the temperature of the spray nozzle during the process from the storage device to the corresponding spray nozzle. This may result in the easily deactivated liquid component being in an inactivated state by the time it is sprayed onto the feed surface, thus affecting the spraying effect of the easily deactivated liquid component on the feed. On the other hand, when the liquid component sprayed onto the feed is a high-viscosity component, the small diameter of the spray nozzle may cause the high-viscosity component to clog the nozzle when passing through it, thereby interrupting the spraying operation and affecting the spraying quality of the liquid component on the feed. There is still room for improvement. Summary of the Invention

Determine whether the actual flow rate of easily deactivated materials is consistent with the preset normal flow rate of easily deactivated materials; If they match, continue to collect the actual flow rate of easily deactivated materials for cyclical judgment; If they are inconsistent, the temperature of the easily deactivated spray nozzle is adjusted by the preset micro-liquid continuous spraying device according to the actual nozzle temperature, the position of the easily deactivated nozzle and the actual flow rate of the easily deactivated material, so as to maintain the activity of the easily deactivated material.

The steps for maintaining the spraying of the feed to be sprayed include: Determine whether the nozzle buildup parameters for viscous materials meet the preset nozzle buildup requirements; If the conditions are not met, continue to collect nozzle accumulation parameters of viscous materials for iterative judgment; If the conditions are met, then determine whether the type of material to be sprayed meets the preset requirements for non-viscous liquid material types; If not, then find an available nozzle position from the preset total spray nozzle positions based on the position of the material to be sprayed; The nozzle translation control component switches the spray nozzles based on the position of the idle nozzle and the position of the nozzle for viscous materials. If the conditions are met, the initial non-sticky material nozzle position is found among the nozzle positions of the material to be sprayed. The micro-liquid continuous spraying device is controlled to clean the spray nozzles based on the initial non-sticky material nozzle position, sticky material nozzle position, and sticky material nozzle accumulation parameters, and to re-coat the feed to be sprayed.

[0010] Optionally, the step of switching the spray nozzle based on the idle nozzle position and the viscous material nozzle position by controlling the nozzle translation control component includes: The displacement between the viscous material nozzle position and the idle nozzle position is calculated based on the preset forward nozzle movement direction to generate the replacement nozzle movement displacement; Calculate the absolute value of the replacement nozzle's movement displacement to generate the replacement nozzle's movement distance; The replacement nozzle travel distances are sorted and compared to generate the shortest replacement nozzle travel distance; The direction of replacement nozzle movement is determined from the displacement of replacement nozzle movement based on the shortest replacement nozzle movement distance. The nozzle translation control component switches the spray nozzle based on the shortest replacement nozzle movement distance and the replacement nozzle movement direction.

[0011] Optionally, the micro-liquid continuous spraying device includes a non-sticky material supply component and an accumulated material collection component. The steps of controlling the micro-liquid continuous spraying device to clean the spray nozzles and re-coat the feed to be sprayed, based on the initial non-sticky material nozzle position, the viscous material nozzle position, and the viscous material nozzle accumulation parameters, include: Collect data on the location of non-sticky material supply, the amount of non-sticky material already sprayed, and the total amount of non-sticky material supplied; The displacement between the initial non-sticky material nozzle position and the sticky material nozzle position is calculated based on the preset positive direction of nozzle movement to generate the sticky material nozzle movement displacement. The nozzle translation control component moves the preset viscous material nozzle to the non-viscous material supply position according to the displacement control of the viscous material nozzle, and connects it to the non-viscous material supply component. Calculate the difference between the total supply of non-sticky material and the amount of non-sticky material already coated to generate the remaining amount of non-sticky material to be coated. The non-sticky material supply component is controlled to flush the viscous material nozzle based on the nozzle accumulation parameters of viscous material and the remaining spray amount of non-sticky material to generate nozzle accumulation material. The control assembly for collecting accumulated material from the nozzles collects the accumulated material and applies additional coating to the feed to be sprayed based on the remaining amount of non-sticky material to be sprayed.

[0012] Optionally, the step of controlling the non-sticky material supply component to flush the viscous material nozzle based on the viscous material nozzle buildup parameters and the remaining non-sticky material coating amount to generate nozzle buildup includes: Find the effective nozzle diameter from the nozzle buildup parameters for viscous materials; Calculate the difference between the square of the ratio between the effective nozzle diameter and the preset initial nozzle diameter and the preset total clogging ratio to generate the viscous material accumulation ratio; Calculate the square of the complement of the bulking ratio of viscous material to generate the nozzle clearance ratio; Calculate the quotient between the preset initial non-viscous material flow rate and the nozzle clearance ratio to generate the actual non-viscous material flow rate; Calculate the quotient between the remaining amount of non-sticky material sprayed and the actual flow rate of the non-sticky material to generate the non-sticky material flushing time; Calculate the quotient between the preset initial liquid spraying pressure and the nozzle clearance ratio to generate the actual liquid spraying pressure; Based on the actual non-viscous material flow rate, non-viscous material flushing time, and actual liquid spraying pressure, the non-viscous material supply component is controlled to inject a preset non-viscous liquid material into the viscous material nozzle to generate nozzle deposit material.

[0013] Secondly, this application provides a nozzle structure control system for a micro-liquid continuous spraying device, which adopts the following technical solution: The nozzle structure control system of the micro-liquid continuous spraying device includes: The data acquisition module is used to collect data on the type of material to be sprayed, the nozzle position of the material to be sprayed, the actual flow rate of easily deactivated materials, the actual nozzle temperature, and the nozzle accumulation parameters of viscous materials. A memory for storing a program for controlling the nozzle structure of a micro-liquid continuous spraying apparatus as described in any of the preceding claims; The processor and the program in the memory can be loaded and executed by the processor to implement the nozzle structure control method of the micro-liquid continuous spraying device as described in any of the above.

[0014] In summary, this application includes at least one of the following beneficial technical effects: 1. By determining whether the material to be sprayed contains easily deactivated materials or viscous materials, if it contains easily deactivated materials, the easily deactivated nozzle position is located among the nozzle positions of the materials to be sprayed. Based on the easily deactivated nozzle position, the easily deactivated material supply component is controlled to spray the easily deactivated material onto the feed to be sprayed. It is then determined whether the actual flow rate of the easily deactivated material is consistent with the normal flow rate. If not, the temperature of the easily deactivated material is adjusted using a preset micro-liquid continuous spraying device based on the actual nozzle temperature, the easily deactivated nozzle position, and the actual easily deactivated material flow rate. The process involves several steps: first, maintaining the activity of easily deactivated materials; second, identifying the location of viscous material nozzles among the nozzles for materials to be sprayed; third, controlling the viscous material supply component to spray the viscous material onto the feed to be sprayed based on the viscous material nozzle location; and fourth, collecting viscous material nozzle accumulation parameters. Finally, controlling a pre-set micro-liquid continuous spraying device to clean the spray nozzles based on the type of material to be sprayed, the location of the viscous material nozzle, and the viscous material nozzle accumulation parameters, in order to maintain the spraying of the feed to be sprayed, thereby reducing waste of the material to be sprayed and improving the quality of material spraying. 2. By determining whether the actual nozzle temperature meets the preset material activity retention temperature requirement, if not, the difference between the actual nozzle temperature and the material retention temperature is calculated to generate the nozzle temperature difference. Based on the nozzle temperature difference and the actual flow rate of the easily deactivated material, the nozzle temperature adjustment component is controlled to adjust the temperature of the easily deactivated spray nozzle, thereby maintaining the activity of the easily deactivated material and improving the spraying effect of the material on the feed. 3. By determining whether the nozzle stacking parameters of the viscous material meet the nozzle stacking requirements, if they do, it is determined whether the type of material to be sprayed meets the requirement of containing non-viscous liquid materials. If not, an idle nozzle position is found in the total spraying nozzle positions based on the position of the material to be sprayed, and the nozzle translation control component is controlled to switch the spraying nozzles based on the idle nozzle position and the viscous material nozzle position. If they do meet the requirements, the initial non-viscous material nozzle position is found in the spraying material nozzle positions, and the micro-liquid continuous spraying device is controlled to clean the spraying nozzles based on the initial non-viscous material nozzle position, the viscous material nozzle position, and the viscous material nozzle stacking parameters, and the micro-liquid continuous spraying device is used to re-coat the feed to be sprayed, thereby alleviating the clogging of the viscous material in the spraying nozzles and improving the spraying effect of the material on the feed.

Detailed Implementation

[0022] To make the purpose, technical solution, and advantages of this application clearer, the following description is provided in conjunction with the appendix. Figures 1 to 7 The present application will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the application.

[0023] This application discloses a nozzle structure control method for a micro-liquid continuous spraying device. This method primarily addresses the nozzle structure control problem of such devices. Specifically, it discloses a spray nozzle, the material to be sprayed, the feed to be sprayed, the micro-liquid continuous spraying device, a nozzle status monitoring device, and a processing terminal. The processing terminal is communicatively connected to both the micro-liquid continuous spraying device and the nozzle status monitoring device to achieve data interaction and control. After receiving the type of the material to be sprayed, the processing terminal determines whether the material contains easily deactivated materials or viscous materials. If the processing terminal determines it contains easily deactivated materials, it controls the nozzle status monitoring device to collect the nozzle temperature and adjusts the nozzle temperature based on this temperature. If the processing terminal determines it contains viscous materials, it controls the micro-liquid continuous spraying device to clean the nozzle. This method aims to quickly and reasonably adjust the micro-liquid continuous spraying device, thereby improving the spraying effect on the feed.

[0024] Reference Figure 1 This application discloses a nozzle structure control method for a micro-liquid continuous spraying device, comprising the following steps: Step S100: Collect the preset types of materials to be sprayed and the nozzle positions of the materials to be sprayed.

[0025] Among them, feed to be sprayed refers to feed that needs to undergo secondary processing after being pelleted and then sprayed with materials.

[0026] The types of materials to be sprayed refer to the collection of liquid feed additives that need to be sprayed onto the feed to be sprayed. In one embodiment, the operator finds the information in the feed processing manual based on the feed to be sprayed.

[0027] The nozzle position of the material to be sprayed refers to the set of position coordinates of the spray nozzles corresponding to the material to be sprayed. In one embodiment, the operator connects the corresponding material storage device to the spray nozzle according to the type of material to be sprayed, marks the connected spray nozzles, and then takes the spray nozzle at the center position among all spray nozzles as the origin of the coordinate system. The two-dimensional rectangular coordinate system is mapped onto the spray nozzle through the processing terminal. Each spray nozzle is taken as a basic unit to obtain the total spray nozzle position. Then, the corresponding position coordinates of the connected spray nozzles are determined according to the markings and summarized to obtain the nozzle position of the material to be sprayed.

[0028] A spray nozzle is a component used to spray materials onto feed, and it can change the spraying angle, pressure, or speed of the materials to be sprayed.

[0029] Step S101: Determine whether the material to be sprayed is a preset type containing easily deactivated materials or a preset type containing sticky materials.

[0030] Among them, "containing easily deactivated materials" refers to the situation where the types of materials to be sprayed contain easily deactivated materials; "containing viscous materials" refers to the situation where the types of materials to be sprayed contain viscous materials; "easily deactivated materials" refers to liquid feed additives that are sensitive to factors such as temperature, flow rate, and contact environment, and whose active ingredients are easily destroyed during the spraying process, resulting in the loss of their original function; "viscous materials" refers to liquid feed additives with high viscosity and poor flowability.

[0031] The processing terminal determines whether the material to be sprayed contains easily deactivated materials or viscous materials, thereby determining whether the temperature of the spray nozzle may need to be adjusted or whether there is material accumulation in the spray nozzle.

[0032] Step S1011: If the material is a type that is prone to deactivation, then locate the location of the deactivation nozzle in the nozzle position of the material to be sprayed.

[0033] If the processing terminal determines that the material to be sprayed contains a type of material that is easily deactivated, it means that the temperature of the spray nozzle needs to be adjusted. Therefore, the processing terminal determines the location of the easily deactivated nozzle, thereby providing data support for subsequent temperature control of the easily deactivated spray nozzle.

[0034] The location of easily deactivated nozzles refers to the coordinates of easily deactivated spray nozzles. The location of easily deactivated nozzles can be obtained by searching the nozzle position of the material to be sprayed on the processing terminal.

[0035] Step S10111: Based on the position of the easily deactivated nozzle, control the preset easily deactivated material supply component to spray the preset easily deactivated material onto the feed to be sprayed, and collect the actual easily deactivated material flow rate and actual nozzle temperature of the preset easily deactivated spray nozzle.

[0036] The flow rate of easily deactivated material refers to the distance traveled per unit time when the easily deactivated material flows through the easily deactivated spray nozzle. The processing terminal controls the easily deactivated material supply component to spray the easily deactivated material onto the feed to be sprayed based on the position of the easily deactivated nozzle, and collects the actual flow rate of the easily deactivated material. In one embodiment, an electromagnetic flow meter is installed at the easily deactivated spray nozzle. The volumetric flow rate of the easily deactivated material is measured by the electromagnetic flow meter when the easily deactivated material flows through the easily deactivated spray nozzle. Then, the operator finds the cross-sectional area of ​​the easily deactivated spray nozzle in the technical manual according to the model of the easily deactivated spray nozzle. Finally, the processing terminal divides the volumetric flow rate of the easily deactivated material by the cross-sectional area to obtain the flow rate of the easily deactivated material.

[0037] The actual nozzle temperature refers to the real-time temperature of the easily deactivated spray nozzle when the feed to be sprayed is being sprayed. In one embodiment, the actual nozzle temperature can be obtained by installing a temperature sensor on the outer wall of the easily deactivated spray nozzle and collecting data from the temperature sensor.

[0038] The easily deactivated material in this step is the same as the easily deactivated material in step S101 above, and will not be described again here.

[0039] A deactivated material supply assembly refers to a device used to store deactivated materials and provide liquid transport power to the material to be sprayed via a pneumatic diaphragm pump.

[0040] A deactivating spray nozzle is a component used to spray deactivating materials onto feed, and it can change the spraying angle, pressure, or speed of the deactivating materials.

[0041] Step S10112: Determine whether the actual flow rate of easily deactivated material is consistent with the preset normal flow rate of easily deactivated material.

[0042] The normal flow rate of easily deactivated materials refers to the distance that the easily deactivated materials travel per unit time when flowing through the easily deactivated spray nozzle in order to maintain their activity. In one embodiment, the operator can find the normal flow rate of easily deactivated materials in the operation manual according to the actual situation and the type of easily deactivated materials. The normal flow rate range of easily deactivated materials for probiotics is 0.5-0.7 m / s, and the normal flow rate range of easily deactivated materials for enzyme preparations is 0.7-1.0 m / s.

[0043] By processing the terminal to determine whether the actual flow rate of the easily deactivated material is consistent with the normal flow rate of the easily deactivated material, it can be determined whether the easily deactivated material supply component is malfunctioning.

[0044] Step S101121: If consistent, continue to collect the actual flow rate of easily deactivated materials for cyclic judgment.

[0045] If the processing terminal determines that the actual flow rate of the easily deactivated material is consistent with the normal flow rate of the easily deactivated material, it indicates that the easily deactivated material supply component has not malfunctioned. Therefore, the processing terminal continues to collect the actual flow rate of the easily deactivated material for cyclical judgment, thereby monitoring the easily deactivated material supply component in real time.

[0046] Step S101122: If there is a discrepancy, the temperature of the easily deactivated spray nozzle is adjusted by the preset micro-liquid continuous spraying device according to the actual nozzle temperature, the position of the easily deactivated nozzle, and the actual flow rate of the easily deactivated material, so as to maintain the activity of the easily deactivated material.

[0047] If the processing terminal determines that the actual flow rate of the easily deactivated material is inconsistent with the normal flow rate, it indicates a malfunction in the easily deactivated material supply component. Therefore, the processing terminal controls the micro-liquid continuous spraying device to adjust the temperature of the easily deactivated spray nozzle based on the actual nozzle temperature, the position of the easily deactivated nozzle, and the actual flow rate of the easily deactivated material. The specific method is described in [reference needed]. Figure 2 This process involves steps to maintain the activity of easily deactivated materials.

[0048] A micro-volume liquid continuous spraying device is a device used to continuously and proportionally add the material to be sprayed to the feed to be sprayed. It consists of multiple spray nozzles, a material supply component, a nozzle temperature adjustment component, a nozzle translation control component, and a material collection component. The spray nozzle is a component used to spray the material to be sprayed onto the feed to be sprayed, and can change the spraying angle, pressure, or speed of the material to be sprayed.

[0049] Material supply components refer to a general term for devices used to store materials to be sprayed and to provide liquid transport power to the materials to be sprayed via pneumatic diaphragm pumps. These include material supply components for easily deactivated materials, viscous materials, and non-viscous materials.

[0050] The nozzle temperature adjustment assembly refers to a heating module used to adjust the temperature of the spray nozzle, which consists of a PTC ceramic heating element attached to the outer wall of the spray nozzle.

[0051] The nozzle translation control component is a device used to translate the spray nozzle. It consists of a conveyor belt that can move in both directions. When it receives the translation direction and translation distance sent by the processing terminal, the nozzle translation control component drives the spray nozzle to translate according to the translation direction and translation distance, so that the target spray nozzle moves to the corresponding position, thereby connecting the target spray nozzle with the corresponding material supply component for spraying the feed to be sprayed.

[0052] The material accumulation collection assembly is a collection device used to collect materials accumulated on the spray nozzle. It consists of a communication module and a collection tank that can be raised and lowered. After receiving an instruction to clean up the accumulated material, the collection tank rises to the position of the spray nozzle, so that the accumulated material falls directly into the collection tank when it is cleaned out of the spray nozzle.

[0053] Step S1012: If the material is viscous, locate the viscous material nozzle position in the nozzle positions of the material to be sprayed.

[0054] If the processing terminal determines that the material to be sprayed is a sticky material, it indicates that there may be material accumulation in the spray nozzle. Therefore, the processing terminal determines the location of the sticky material nozzle, thus providing data support for determining whether the nozzle needs to be cleaned.

[0055] The nozzle position for viscous materials refers to the coordinates of the corresponding spray nozzle for the viscous material. The nozzle position for viscous materials can be obtained by searching for the nozzle position of the material to be sprayed on the processing terminal.

[0056] Step S10121: Control the preset viscous material supply component to spray the preset viscous material onto the feed to be sprayed according to the position of the viscous material nozzle, and collect the viscous material nozzle accumulation parameters.

[0057] Among them, the viscous material nozzle accumulation parameter refers to the physical quantity used to reflect the degree of accumulation of viscous material in the spray nozzle, including the effective nozzle diameter and the internal pressure difference of the nozzle. By controlling the viscous material supply component to spray the viscous material to the feed to be sprayed according to the position of the viscous material nozzle through the processing terminal, and collecting and summarizing the effective nozzle diameter and the internal pressure difference of the nozzle, the viscous material nozzle accumulation parameter can be obtained.

[0058] The effective nozzle diameter refers to the diameter of the channel through which the viscous material can actually flow in the spray nozzle corresponding to the viscous material. In one embodiment, a miniature camera is installed at the outlet of the spray nozzle corresponding to the viscous material, and the flow orifice is identified by the image processing of the miniature camera. The output identification data is the effective nozzle diameter.

[0059] The internal pressure difference of a nozzle refers to the pressure difference between the inlet and outlet of a spray nozzle when a viscous material flows through it. In one embodiment, the internal pressure difference of a nozzle can be obtained by installing a pressure sensor at the inlet of the corresponding spray nozzle and measuring the spray nozzle with the pressure sensor.

[0060] A viscous material supply assembly is a device used to store viscous materials and provide liquid transport power to the material to be sprayed via a pneumatic diaphragm pump.

[0061] Step S10122: Based on the type of material to be sprayed, the nozzle position of the viscous material, and the nozzle accumulation parameters of the viscous material, the preset micro-liquid continuous spraying device is controlled to clean the preset spraying nozzles in order to maintain the spraying of the feed to be sprayed.

[0062] The micro-liquid continuous spraying device cleans the spray nozzles according to the type of material to be sprayed, the nozzle position for viscous materials, and the nozzle buildup parameters for viscous materials. Specific methods are described in [reference needed]. Figure 4 The steps are to maintain the spraying of the feed to be sprayed.

[0063] The micro-liquid continuous spraying device in this step is the same as the micro-liquid continuous spraying device in step S10132 above, and the spraying nozzle in this step is the same as the spraying nozzle in step S100 above, so it will not be described again here.

[0064] Reference Figure 2The steps of controlling the temperature of the easily deactivated spray nozzles in a pre-set micro-liquid continuous spraying device, based on the actual nozzle temperature, the position of the easily deactivated nozzles, and the actual flow rate of the easily deactivated material, to maintain the activity of the easily deactivated material include: Step S200: Determine whether the actual nozzle temperature meets the preset material activity retention temperature requirement.

[0065] The material activity retention temperature refers to the temperature at which the activity of the easily deactivated material is normal. In one embodiment, the material activity retention temperature is 20℃-30℃. The requirement for the material activity retention temperature means that in order to maintain the activity of the easily deactivated material, the easily deactivated material must be kept within the range of the material activity retention temperature.

[0066] The processing terminal determines whether the actual nozzle temperature meets the requirements for maintaining the activity of the material, thereby determining whether the temperature of the easily deactivated spray nozzle needs to be adjusted.

[0067] Step S2001: If satisfied, continue to collect the actual nozzle temperature for cyclic judgment.

[0068] If the processing terminal determines that the actual nozzle temperature meets the requirements for maintaining the activity of the material, it means that there is no need to adjust the temperature of the easily deactivated spray nozzle. Therefore, the processing terminal continues to collect the actual nozzle temperature for cyclic judgment, thereby monitoring the temperature of the easily deactivated spray nozzle in real time and ensuring the activity of the easily deactivated material.

[0069] Step S2002: If not satisfied, calculate the difference between the actual nozzle temperature and the material holding temperature to generate the nozzle temperature difference.

[0070] If the processing terminal determines that the actual nozzle temperature does not meet the requirements for maintaining the activity of the material, it indicates that the temperature of the easily deactivated spray nozzle needs to be adjusted. Therefore, the processing terminal determines the nozzle temperature difference to provide data support for subsequent adjustment of the temperature of the easily deactivated spray nozzle.

[0071] Nozzle temperature difference refers to the temperature that easily deactivated spray nozzles need to be adjusted. The nozzle temperature difference can be obtained by subtracting the material holding temperature from the actual nozzle temperature through the processing terminal.

[0072] Step S20021: Adjust the temperature of the easily deactivated spray nozzle by controlling the nozzle temperature adjustment component according to the nozzle temperature difference and the actual flow rate of the easily deactivated material.

[0073] In this process, after the processing terminal determines the nozzle temperature difference and the actual flow rate of the easily deactivated material, the processing terminal controls the nozzle temperature adjustment component to adjust the temperature of the easily deactivated spray nozzle based on the nozzle temperature difference and the actual flow rate of the easily deactivated material. The specific method is described in [reference needed]. Figure 3This process maintains the activity of easily deactivated materials, thereby improving the spraying effect of easily deactivated liquid components on feed.

[0074] Reference Figure 3 The steps for adjusting the temperature of the easily deactivated spray nozzle by controlling the nozzle temperature adjustment component based on the nozzle temperature difference and the actual flow rate of the easily deactivated material include: Step S300: Calculate the product between the preset reference temperature correction parameter and the nozzle temperature difference to generate the temperature power correction amount.

[0075] The temperature-power correction amount refers to the adjustment of power by temperature. The processing terminal determines whether the nozzle temperature difference is positive. If it is positive, it means that the temperature of the easily deactivated spray nozzle is too high and needs to be cooled down. In this case, the reference temperature correction parameter is negative. If it is negative, it means that the temperature of the easily deactivated spray nozzle is too low and needs to be heated up. In this case, the reference temperature correction parameter is positive. Multiplying the reference temperature correction parameter by the nozzle temperature difference amount yields the temperature-power correction coefficient.

[0076] The reference temperature correction parameter refers to the percentage change in power for every 1°C change in temperature. In one embodiment, when the nozzle temperature difference is positive, the reference temperature correction parameter is -0.05W / °C, and when the nozzle temperature difference is negative, the reference temperature correction parameter is 0.05W / °C.

[0077] Step S301: Calculate the product between the quotient of the actual flow rate of easily deactivated material and the normal flow rate of easily deactivated material and the preset rated power to generate the flow rate power correction amount.

[0078] Among them, the flow rate power correction amount refers to the correction amount of the power by the flow rate of easily deactivated materials. The flow rate power correction coefficient can be obtained by dividing the normal flow rate of easily deactivated materials by the actual flow rate of easily deactivated materials through the processing terminal, and then multiplying the obtained ratio by the rated power.

[0079] Rated power refers to the arithmetic average of the maximum and minimum power that the nozzle temperature adjustment component is allowed to output when heating continuously, safely and stably. In one embodiment, the operator can find the maximum and minimum power in the technical manual according to the model of the nozzle temperature adjustment component. Then, the maximum and minimum power are added together by the processing terminal, and the sum is divided by 2 to obtain the rated power.

[0080] Step S302: Calculate the sum of the temperature power correction, the flow rate power correction, and the rated power to generate the actual nozzle heating power.

[0081] The actual nozzle heating power refers to the actual output power of the nozzle temperature adjustment component when heating the spray nozzle. The temperature power correction amount and flow rate power correction amount are added to the rated power by the processing terminal. It is then determined whether the sum is greater than the maximum power or less than the minimum power. If it is greater than the maximum power, the maximum power is determined as the actual nozzle heating power; if it is less than the minimum power, the minimum power is determined as the actual nozzle heating power; if it is neither greater than the maximum power nor less than the minimum power, the sum is determined as the actual nozzle heating power.

[0082] Step S303: Adjust the temperature of the easily deactivated spray nozzle by controlling the nozzle temperature adjustment component according to the actual nozzle heating power.

[0083] In this process, after the actual nozzle heating power is determined at the processing terminal, the temperature of the easily deactivated spray nozzle is adjusted by the nozzle temperature adjustment component based on the actual nozzle heating power, thereby maintaining the activity of the easily deactivated material.

[0084] Reference Figure 4 The steps for cleaning the preset spray nozzles of a micro-liquid continuous spraying device, based on the type of material to be sprayed, the nozzle position for viscous materials, and the nozzle accumulation parameters for viscous materials, to maintain the spraying of the feed to be sprayed, include: Step S400: Determine whether the nozzle accumulation parameters of the viscous material meet the preset nozzle accumulation requirements.

[0085] Among them, the nozzle accumulation requirement refers to the accumulation of viscous material in the corresponding spray nozzle when the internal pressure difference of the nozzle in the nozzle accumulation parameter is greater than 0 Pa.

[0086] The processing terminal determines whether the nozzle accumulation parameters of the viscous material meet the nozzle accumulation requirements, thereby determining whether the viscous material is accumulated in the corresponding spray nozzle.

[0087] Step S4001: If not satisfied, continue to collect the nozzle accumulation parameters of viscous material for cyclic judgment.

[0088] If the processing terminal determines that the nozzle accumulation parameters of the viscous material do not meet the nozzle accumulation requirements, it means that there is no accumulation of the viscous material in the corresponding spray nozzle. Therefore, the processing terminal continues to collect the nozzle accumulation parameters of the viscous material for cyclic judgment, thereby monitoring the material accumulation parameters of the corresponding spray nozzle of the viscous material in real time, so as to ensure that the micro-liquid continuous spraying device can continuously spray the feed to be sprayed.

[0089] Step S4002: If satisfied, determine whether the type of material to be sprayed meets the preset requirement of containing non-viscous liquid material.

[0090] If the processing terminal determines that the nozzle accumulation parameters of the viscous material meet the nozzle accumulation requirements, it indicates that the viscous material is accumulated in the corresponding spray nozzle. Therefore, the processing terminal determines whether the type of material to be sprayed meets the requirements of containing non-viscous liquid material, thereby determining whether the spray nozzle corresponding to the viscous material can be cleaned by using non-viscous liquid material.

[0091] The requirement to include non-sticky liquid materials means that the types of materials to be sprayed must include non-sticky liquid materials.

[0092] Non-viscous liquid materials refer to liquid feed additives with low viscosity and high fluidity.

[0093] Step S40021: If not satisfied, find an available nozzle position in the preset total spray nozzle positions according to the position of the material to be sprayed.

[0094] If the processing terminal determines that the type of material to be sprayed does not meet the requirement of containing non-viscous liquid materials, it means that the non-viscous liquid materials cannot be used to clean the spray nozzles corresponding to the viscous materials. Therefore, the processing terminal determines the location of the idle nozzles to provide data support for subsequent switching of spray nozzles.

[0095] The idle nozzle position refers to the set of position coordinates of all unused spray nozzles. The idle nozzle position is obtained by marking the position of the material to be sprayed in the total spray nozzle position through the processing terminal, extracting the position coordinates of the unmarked positions in the total spray position and summarizing them.

[0096] The position of the main spray nozzle in this step is the same as that in step S100 above, and will not be repeated here.

[0097] Step S400211: Control the nozzle translation control component to switch the spray nozzle according to the position of the idle nozzle and the position of the viscous material nozzle.

[0098] The process involves using a processing terminal to control a nozzle translation control component to switch between spray nozzles based on the nozzle positions of the materials to be sprayed and the nozzle positions of viscous materials. For specific details, please refer to [link to relevant documentation]. Figure 5 The steps are as follows, thereby enabling the continuous spraying of feed to be sprayed by the micro-liquid continuous spraying device.

[0099] Step S40022: If satisfied, find the initial non-sticky material nozzle position in the nozzle positions of the material to be sprayed.

[0100] If the processing terminal determines that the type of material to be sprayed meets the requirement of containing non-sticky liquid materials, it means that the spray nozzle corresponding to the sticky material can be cleaned by using non-sticky liquid materials. Therefore, the initial position of the non-sticky material nozzle is determined by the processing terminal, thereby providing data support for subsequent cleaning of the spray nozzle corresponding to the sticky material by using non-sticky liquid materials.

[0101] The initial non-sticky material nozzle position refers to the position coordinates of the spray nozzle corresponding to the non-sticky liquid material. The initial non-sticky material nozzle position can be obtained by searching in the nozzle position of the material to be sprayed by the processing terminal.

[0102] Step S400221: Based on the initial non-sticky material nozzle position, viscous material nozzle position, and viscous material nozzle accumulation parameters, control the micro-liquid continuous spraying device to clean the spray nozzles and re-coat the feed to be sprayed.

[0103] In this process, after the initial non-sticky material nozzle position is determined at the processing terminal, the terminal controls the micro-liquid continuous spraying device to clean the spray nozzles based on the initial non-sticky material nozzle position, the viscous material nozzle position, and the viscous material nozzle accumulation parameters. It also performs touch-up coating on the feed to be sprayed. The specific method is described in [reference needed]. Figure 6 This process alleviates the problem of viscous material accumulating in the corresponding spray nozzle.

[0104] Reference Figure 5 The steps for switching spray nozzles by controlling the nozzle translation control component based on the idle nozzle position and the nozzle position of viscous materials include: Step S500: Calculate the displacement between the viscous material nozzle position and the idle nozzle position according to the preset forward nozzle movement direction, so as to generate the replacement nozzle movement displacement.

[0105] The replacement nozzle movement displacement refers to the data set of distances and directions that all idle spray nozzles need to move to the position of the viscous material nozzle when they are translated. The processing terminal subtracts the Y-axis coordinate component of the viscous material nozzle position from the Y-axis coordinate component of the idle nozzle position and summarizes them to obtain a coordinate difference set. The processing terminal classifies the data in the coordinate difference set according to positive and negative values, and matches the positive values ​​with the positive nozzle movement direction to obtain the positive movement displacement. The reverse nozzle movement direction matches the negative values ​​with the reverse movement displacement to obtain the reverse movement displacement. Finally, the positive and reverse movement displacements are summarized to obtain the replacement nozzle movement displacement.

[0106] The forward nozzle movement direction refers to the positive direction when the spray nozzle is translated. In one embodiment, the forward nozzle movement direction is the leftward movement of the translation control component. The reverse nozzle movement direction refers to the opposite direction when the spray nozzle is translated. In one embodiment, the reverse nozzle movement direction is the rightward movement of the translation control component.

[0107] Step S501: Calculate the absolute value of the replacement nozzle movement displacement to generate the replacement nozzle movement distance.

[0108] The replacement nozzle movement distance refers to the set of distances that all idle spray nozzles in the spray nozzles need to move to the position of the viscous material nozzle. The absolute value of the replacement nozzle movement displacement data is calculated by the processing terminal, and the calculated data is summarized to obtain the replacement nozzle movement distance.

[0109] Step S502: Sort and compare the replacement nozzle movement distances to generate the shortest replacement nozzle movement distance.

[0110] The shortest replacement nozzle movement distance refers to the distance between the spray nozzle corresponding to the viscous material and the nearest idle spray nozzle. The data of the replacement nozzle movement distance is sorted in descending order by the processing terminal, and the smallest data is extracted to obtain the shortest replacement nozzle movement distance.

[0111] Step S503: Find the direction of replacement nozzle movement in the replacement nozzle movement displacement based on the shortest replacement nozzle movement distance.

[0112] The replacement nozzle movement direction refers to the translation direction of the idle spray nozzle that is closest to the spray nozzle corresponding to the viscous material. The replacement nozzle movement direction can be obtained by searching in the replacement nozzle movement displacement according to the shortest replacement nozzle movement distance through the processing terminal.

[0113] Step S505: Control the nozzle translation control component to switch the spray nozzle based on the shortest replacement nozzle movement distance and the replacement nozzle movement direction.

[0114] In this process, after the processing terminal determines the shortest replacement nozzle moving distance and the replacement nozzle moving direction, the processing terminal controls the nozzle translation control component to switch the spraying nozzle according to the shortest replacement nozzle moving distance and the replacement nozzle moving direction, thereby providing support for the subsequent control of the micro-liquid continuous spraying device to spray viscous materials onto the feed to be sprayed.

[0115] Reference Figure 6 The steps of controlling the micro-liquid continuous spraying device to clean the spray nozzles and re-coat the feed to be sprayed, based on the initial non-sticky material nozzle position, viscous material nozzle position, and viscous material nozzle accumulation parameters, include: Step S600: Collect the non-stick material supply location, the amount of non-stick material already sprayed, and the total amount of non-stick material supplied.

[0116] The non-stick material supply position refers to the position coordinates of the interface connecting the non-stick material supply component to the spray nozzle. The processing terminal takes the spray nozzle at the center position among all spray nozzles as the origin of the coordinate system, and then maps the two-dimensional rectangular coordinate system onto the spray nozzle and the material supply component. Taking each spray nozzle and each material supply component as a basic unit, the total spray nozzle position and the total material supply component position can be obtained. The processing terminal finds the position coordinates in the total material supply component position that are consistent with the Y-axis coordinate component of the initial non-stick material nozzle position, and thus obtains the non-stick material supply position.

[0117] The amount of non-sticky material sprayed refers to the volume of non-sticky material that has been sprayed onto the feed to be sprayed. In one embodiment, the amount of non-sticky material sprayed is obtained by installing an electromagnetic flowmeter at the outlet of the pneumatic diaphragm pump in the material supply assembly for real-time measurement and accumulating the measurement results. When the flowmeter receives the data acquisition signal from the processing terminal, the accumulated data is sent to the processing terminal.

[0118] The total supply of non-sticky material refers to the total volume of non-sticky material that needs to be sprayed onto the feed to be sprayed. In one embodiment, the operator can find the total supply of non-sticky material in the operation manual according to the actual situation and the type of feed to be sprayed.

[0119] Step S601: Calculate the displacement between the initial non-sticky material nozzle position and the sticky material nozzle position according to the preset positive direction of nozzle movement, so as to generate the sticky material nozzle movement displacement.

[0120] The nozzle movement displacement for viscous materials refers to the data set of distance and direction that the spray nozzle corresponding to the viscous material needs to move to the initial position of the non-viscous material nozzle. The processing terminal subtracts the Y-axis coordinate component of the initial non-viscous material nozzle position from the Y-axis coordinate component of the viscous material nozzle position, and then determines whether the calculated difference is positive. If it is positive, the positive direction of nozzle movement is matched with the difference to obtain the nozzle movement displacement for viscous materials; if it is negative, the negative direction of nozzle movement is matched with the difference to obtain the nozzle movement displacement for viscous materials.

[0121] The positive direction of nozzle movement refers to the positive direction of the spray nozzle translation. In one embodiment, the positive direction of nozzle movement is the leftward movement of the translation control component. The negative direction of nozzle movement refers to the opposite direction of the spray nozzle translation. In one embodiment, the negative direction of nozzle movement is the rightward movement of the translation control component.

[0122] Step S602: Based on the displacement of the viscous material nozzle, the nozzle translation control component moves the preset viscous material nozzle to the non-viscous material supply position and connects it to the non-viscous material supply component.

[0123] Specifically, after the processing terminal determines the moving displacement of the viscous material nozzle, it controls the nozzle translation control component to move the viscous material nozzle to the non-viscous material supply position based on the moving displacement of the viscous material nozzle, and connects it with the non-viscous material supply component, thereby providing support for the subsequent control of the non-viscous material attack component to flush the viscous material nozzle.

[0124] A viscous material nozzle is a component used to spray viscous materials onto feed, and it can change the spraying angle, pressure, or speed of the viscous material.

[0125] Step S603: Calculate the difference between the total supply of non-sticky material and the amount of non-sticky material already coated to generate the remaining amount of non-sticky material to be coated.

[0126] The remaining amount of non-sticky material to be sprayed refers to the volume of non-sticky liquid material that still needs to be sprayed onto the feed. The remaining amount of non-sticky material to be sprayed can be obtained by subtracting the amount of non-sticky material already sprayed from the total amount of non-sticky material supplied by the processing terminal.

[0127] Step S604: Based on the nozzle accumulation parameters of viscous material and the remaining spray amount of non-viscous material, control the non-viscous material supply component to flush the viscous material nozzle to generate nozzle accumulation material.

[0128] Specifically, after the processing terminal determines the nozzle accumulation parameters for viscous materials and the remaining spray amount for non-viscous materials, the processing terminal controls the non-viscous material supply component to flush the viscous material nozzles based on the nozzle accumulation parameters and the remaining spray amount for non-viscous materials. The specific method for obtaining the nozzle accumulation material is described in [reference needed]. Figure 7 This process alleviates the accumulation of viscous materials at the nozzle, thereby ensuring continuous spraying of the feed to be sprayed by the micro-liquid continuous spraying device.

[0129] Nozzle deposit material refers to the sticky material and non-sticky liquid material that assists in cleaning collected in the deposit material collection assembly and removed from the spray nozzle.

[0130] Step S605: Control the material accumulation collection component to collect the material accumulated in the nozzle, and re-coat the feed to be sprayed according to the remaining amount of non-sticky material.

[0131] The process involves controlling the material collection component to move to the viscous material nozzle position and collect the accumulated material. After collection, the material collection component is moved back to its initial position. The processing terminal then controls the nozzle translation control component to move in the opposite direction of the viscous material nozzle's movement, thereby restoring the non-viscous material nozzle and the viscous material nozzle to their corresponding positions on the non-viscous material supply component and the viscous material supply component. The non-viscous material nozzle is then connected to the non-viscous material supply component, and the viscous material nozzle is connected to the viscous material supply component. Finally, based on the remaining amount of non-viscous material to be coated, the non-viscous material supply component is controlled to spray non-viscous liquid feed onto the feed to be coated. Based on the mass of accumulated viscous material in the nozzle's accumulated material, the viscous material supply component is controlled to spray viscous material onto the feed to be coated, thus avoiding the mixing of non-viscous liquid material and viscous material, and enabling recoating of the feed to be coated.

[0132] The mass of the viscous material in the nozzle accumulation refers to the mass of the viscous material in the nozzle accumulation material. In one embodiment, the operator filters out the viscous material in the nozzle accumulation material and weighs it through a weighing module to obtain the mass of the viscous material in the nozzle accumulation.

[0133] Reference Figure 7 The step of controlling the non-sticky material supply component to flush the viscous material nozzle based on the nozzle buildup parameters of the viscous material and the remaining coating amount of the non-sticky material to generate nozzle buildup includes: Step S700: Find the effective nozzle diameter in the nozzle accumulation parameters for viscous materials.

[0134] In this step, the effective nozzle diameter is the same as that in step S401 above. The effective nozzle diameter can be obtained by searching in the nozzle accumulation parameters of viscous materials by the processing terminal.

[0135] Step S701: Calculate the difference between the square of the ratio between the effective nozzle diameter and the preset initial nozzle diameter and the preset total blockage ratio to generate the viscous material accumulation ratio.

[0136] The viscous material accumulation ratio refers to the ratio between the flow cross-sectional area of ​​the spray nozzle when viscous material accumulates in the spray nozzle and the flow cross-sectional area of ​​the spray nozzle when there is no accumulation. The viscous material accumulation ratio is obtained by dividing the effective nozzle diameter by the initial nozzle diameter at the processing terminal, calculating the square of the quotient, and finally subtracting the square value from the total blockage ratio.

[0137] The initial nozzle diameter refers to the diameter at the nozzle outlet under conditions where there is no material buildup. In one embodiment, the operator can find the initial nozzle diameter in the technical manual according to the nozzle model.

[0138] The total clogging ratio refers to the ratio between the flow cross-sectional area of ​​the spray nozzle when it is completely clogged and the flow cross-sectional area of ​​the spray nozzle when it is free of clogging. In one embodiment, the total clogging ratio is 1.

[0139] Step S702: Calculate the square of the complement of the viscous material packing ratio to generate the nozzle clearance ratio.

[0140] The nozzle clearance ratio refers to the square of the ratio between the remaining flow cross-sectional area of ​​the spray nozzle when viscous material accumulates in the spray nozzle and the flow cross-sectional area of ​​the spray nozzle when there is no accumulation. The nozzle clearance ratio can be obtained by subtracting the viscous material accumulation ratio from 1 by the processing terminal and then calculating the square of the difference.

[0141] Step S703: Calculate the quotient between the preset initial non-viscous material flow rate and the nozzle gap ratio to generate the actual non-viscous material flow rate.

[0142] The actual non-viscous material flow rate refers to the distance that a non-viscous liquid material travels per unit time when it flows through a viscous material nozzle. The actual non-viscous material flow rate can be obtained by dividing the initial non-viscous material flow rate by the nozzle clearance ratio through the processing terminal.

[0143] The initial non-viscous material flow rate refers to the distance a non-viscous liquid material travels per unit time when it passes through the corresponding spray nozzle. In one embodiment, the operator can find the initial non-viscous material flow rate in the operation manual according to the actual situation and the type of feed to be sprayed.

[0144] Step S704: Calculate the quotient between the remaining amount of non-sticky material sprayed and the actual flow rate of non-sticky material to generate the non-sticky material flushing time.

[0145] The non-sticky material flushing time refers to the time required for the non-sticky liquid material to flush the viscous material nozzle. The non-sticky material flushing time can be obtained by dividing the remaining amount of non-sticky material sprayed by the actual non-sticky material flow rate through the processing terminal.

[0146] Step S705: Calculate the quotient between the preset initial liquid spraying pressure and the nozzle gap ratio to generate the actual liquid spraying pressure.

[0147] The actual liquid spraying pressure refers to the scouring pressure when a non-viscous liquid material scours a viscous material nozzle. The actual liquid spraying pressure can be obtained by dividing the initial liquid spraying pressure by the nozzle clearance ratio through the processing terminal.

[0148] The initial liquid spraying pressure refers to the pressure exerted by a non-viscous liquid material on the corresponding spraying nozzle when it flows through the nozzle. In one embodiment, the operator can find the initial liquid spraying pressure in the operation manual according to the actual situation and the type of feed to be sprayed.

[0149] Step S706: Based on the actual non-sticky material flow rate, non-sticky material flushing time, and actual liquid spraying pressure, control the non-sticky material supply component to inject a preset non-sticky liquid material into the viscous material nozzle to generate nozzle deposit material.

[0150] In this step, the nozzle accumulation material is the same as the nozzle accumulation material in step S604 above. After the processing terminal determines the actual non-sticky material flow rate, non-sticky material flushing time, and actual liquid spraying pressure, the processing terminal controls the non-sticky material supply component to inject non-sticky liquid material into the viscous material nozzle according to the actual non-sticky material flow rate, non-sticky material flushing time, and actual liquid spraying pressure, thereby obtaining the nozzle accumulation material and alleviating the accumulation of viscous material at the viscous material nozzle.
