Description

Technical Field

[0001] The present application relates to the technical field of glaze pretreatment in the field of glass processing, and in particular to a multifunctional glass glaze filter and mixer. Background Art

[0002] In the photovoltaic glass screen printing process, the quality of glass glaze pretreatment directly affects screen printing accuracy and product yield. In traditional glass glaze preparation, stirring and filtration are usually performed independently, and the filtration equipment often uses open mesh screens or single-mesh gauze, resulting in the following technical bottlenecks: 1. Low efficiency: Stirring and filtration are performed in separate steps, taking a total of 40-90 minutes. In addition, high-viscosity glaze relies on natural gravity filtration, resulting in a slow flow rate, making it difficult to meet the needs of industrialized efficient production. 2. Incomplete filtration: The manual mesh matching accuracy is insufficient, and large-aperture mesh is preferred to increase the speed, resulting in large particles of impurities remaining, which can easily clog the screen and cause pattern defects during screen printing; 3. High maintenance cost: The open structure is easily contaminated by environmental impurities. Particles accumulate and clog the mesh, requiring frequent manual stirring. In addition, traditional mesh has poor wear resistance and requires high replacement frequency. 4. Complicated operation: Pressure control relies on low pressure or natural gravity, stirring position and frequency require manual intervention, and there is a lack of automatic adjustment mechanism, making it difficult to adapt to the filtration requirements of glazes with different viscosities.

[0003] In existing technologies, the mixing and filtering equipment functions are separated, and the pressure control, mesh cleaning, and sealing design of the filtration process have significant flaws. This makes the glaze pretreatment process a key bottleneck restricting the efficiency and quality of screen printing. There is an urgent need for an integrated, automated, multifunctional device that can achieve efficient filtration during the mixing process while also solving problems such as clogging, contamination, and parameter adjustment.

By adjusting the pressurization pressure and the stirring position, stirring and filtering are achieved. The closed glass glaze barrel is connected by threads to reduce the contact of the glass glaze with the air and the emission of odor.

[0006] In some embodiments, the raising and lowering of the stirring rod is controlled by the raising and lowering buttons, and the stirring brush contacts the mesh surface when it reaches the lowest point to clean the particles on the mesh, including: the two ends of the lifting frequency control spring are respectively connected to the filter mixer bracket and the stirring rod, and the lifting and lowering stroke of the stirring rod is limited by the elastic deformation of the spring to prevent excessive lifting; a guide rail is provided on the outside of the stirring rod, which slides with the guide groove on the barrel cover to ensure that the stirring rod moves in the vertical direction when it is raised and lowered, so that the stirring brush contacts the mesh surface with uniform pressure, thereby effectively cleaning the particles on the mesh surface.

[0007] In some embodiments, filtration is performed during the stirring process of the glass glaze, and filtering is achieved while stirring by adjusting the pressurized pressure and the stirring position, including: a pressurized interface is provided on the top of the glass glaze barrel, which is connected to a low-pressure air source through a hose, and the filter mixer control panel has a built-in pressure sensor and controller, which can adjust the pressurized pressure according to the viscosity parameters of the glass glaze; the lifting position of the stirring rod corresponds to multiple stirring areas, and when the stirring head is located in the upper middle part of the barrel body, the glaze is mixed by the rotation of the stirring brush, and when it drops to the surface of the mesh, the mesh is cleaned and pressurized filtration is performed, so that the glaze passes through the high-strength composite mesh under pressure drive, and large particles of impurities are retained above the high-strength composite mesh.

[0008] In some embodiments, the control of the rotation of the stirring rod to achieve stirring and cleaning of the stirring head includes: the stirring brush of the stirring head is made of elastic wear-resistant material and is spirally distributed around the stirring head. When the button is turned to control the stirring rod to rotate at a low speed, the stirring brush stirs the glass glaze clockwise or counterclockwise to prevent particles from settling; when the filtration speed is detected to drop, the filter mixer control screen is switched to high-speed rotation mode, and the stirring brush cleans the mesh surface with a high-frequency reciprocating rotation to peel off blocked particles, and controls the stirring rod to rise and fall slightly to enhance the cleaning effect.

[0009] In some embodiments, the mesh replacement valve includes a rectangular opening arranged on the side wall of the glass glaze barrel, and the opening edge of the rectangular opening is provided with an annular groove. The high-strength composite mesh is fixed in the annular groove by a detachable elastic pressure ring, and a rotary lock is provided on the outside of the elastic pressure ring. The high-strength composite mesh can be quickly replaced by tightening the rotary lock; a sealing ring is provided on the inside of the mesh replacement valve to ensure that the sealing inside the barrel is not destroyed during the replacement process.

[0010] In some embodiments, the filter mixer control panel has a built-in intelligent control module, and the intelligent control module has multiple sets of filtering programs preset. Each set of filtering programs corresponds to high-strength composite mesh with different mesh sizes, so as to automatically match the mesh size according to the mesh size of the silk screen printing screen, and adjust the stirring frequency, pressurization pressure and cleaning cycle to realize intelligent configuration of filtering parameters.

[0011] In some embodiments, the high-strength composite mesh is interwoven with stainless steel wire and polytetrafluoroethylene fiber, the mesh mesh range is 200-400 mesh, and the surface of the mesh is coated with a nano-scale anti-stick coating. The nano-scale anti-stick coating is used to reduce the adsorption force of particles and cooperate with the cleaning effect of the stirring brush to further reduce mesh clogging.

[0012] In some embodiments, it also includes: a micro air pump and a pressure regulating valve, wherein the micro air pump is electrically connected to the filter mixer control panel, and the target pressure value is input through the filter mixer control panel. The pressure regulating valve provides real-time feedback of the pressure inside the glass glaze barrel and automatically calibrates, so that the pressurized pressure can be continuously adjusted within the range of 0.1-0.5MPa to adapt to glass glazes of different viscosities.

[0013] In some embodiments, a spiral guide groove is provided on the surface of the spherical bead of the rotary valve. When the stirring rod rotates, the guide groove guides the lubricating oil to form a lubricating film between the spherical bead and the valve seat, reducing the rotational friction torque. The inclination angle of the guide groove is designed to enable the stirring rod to drive the spherical bead to swing slightly during the lifting process, thereby avoiding the entanglement and knotting of the rotation control line.

[0014] In some embodiments, the filter agitator fixed balance rod includes an adjustable foot symmetrically arranged at the bottom of the filter agitator bracket, the adjustable foot is connected to the filter agitator bracket through a thread, and the bottom of the adjustable foot is provided with a non-slip rubber pad. The adjustable foot is rotated to adjust the horizontality of the multifunctional glass glaze filter agitator to ensure the stability of the multifunctional glass glaze filter agitator during the stirring process and reduce the mesh deviation or glaze splashing caused by vibration.

[0015] The multifunctional glass glaze filter mixer provided by the present application includes core components such as a filter mixer control panel, a lifting frequency control spring, a rotary valve, a stirring head, and a high-strength composite mesh. By arranging a replaceable high-strength composite mesh in the glass glaze barrel, the lifting and rotation of the stirring rod are adjusted through the control panel to achieve synchronous filtration during the stirring process, breaking the traditional step-by-step operation mode of "stirring first and then filtering"; the glass glaze barrel is connected to the barrel cover through a threaded connection, and the switch valve design of the adding funnel is used to reduce the contact between the glaze and the air and the release of odor, thereby avoiding environmental impurity pollution; the raising / lowering button is used to control the stirring brush on the stirring head to contact the mesh surface, and the turning button is used to drive the stirring rod to rotate, thereby realizing the combination of stirring and mixing with the cleaning function of particles blocked by the mesh; the pressurization pressure and stirring position are adjusted through the control panel to adapt to the filtration requirements of glazes of different viscosities, ensuring that the glaze passes through the mesh evenly under stable pressure, thereby improving the filtration efficiency.

[0016] Stirring and filtering are carried out simultaneously, and the total time is shortened compared with traditional methods, which significantly improves the efficiency of screen printing pre-preparation; the closed structure is combined with replaceable high-strength composite mesh to achieve precise matching with the screen mesh count, effectively remove large particles of impurities, and reduce the screen clogging rate and pattern defect rate; the control panel automatically adjusts the stirring frequency, cleaning cycle and pressurization pressure to reduce manual intervention. At the same time, the high-strength mesh and dynamic cleaning design extend the service life of the equipment and reduce maintenance costs; the fully enclosed design reduces volatile gas emissions and impurity pollution, and the emergency button and lifting limit structure improve operational safety, meeting the environmental protection and safety standards of industrial production.

[0028] In the photovoltaic glass screen printing process, the quality of glass glaze pretreatment directly affects screen printing accuracy and product yield. In traditional glass glaze preparation, stirring and filtration are usually performed independently, and the filtration equipment often uses open mesh screens or single-mesh gauze, resulting in the following technical bottlenecks: 1. Low efficiency: Stirring and filtration are performed in separate steps, taking a total of 40-90 minutes. In addition, high-viscosity glaze relies on natural gravity filtration, resulting in a slow flow rate, making it difficult to meet the needs of industrialized efficient production. 2. Incomplete filtration: The manual mesh matching accuracy is insufficient, and large-aperture mesh is preferred to increase the speed, resulting in large particles of impurities remaining, which can easily clog the screen and cause pattern defects during screen printing; 3. High maintenance cost: The open structure is easily contaminated by environmental impurities. Particles accumulate and clog the mesh, requiring frequent manual stirring. In addition, traditional mesh has poor wear resistance and requires high replacement frequency. 4. Complicated operation: Pressure control relies on low pressure or natural gravity, stirring position and frequency require manual intervention, and there is a lack of automatic adjustment mechanism, making it difficult to adapt to the filtration requirements of glazes with different viscosities.

[0029] In existing technologies, the mixing and filtering equipment functions are separated, and the pressure control, mesh cleaning, and sealing design of the filtration process have significant flaws. This makes the glaze pretreatment process a key bottleneck restricting the efficiency and quality of screen printing. There is an urgent need for an integrated, automated, multifunctional device that can achieve efficient filtration during the mixing process while also solving problems such as clogging, contamination, and parameter adjustment.

[0030] To solve the above problems, please refer to Figure 1The present application provides a multifunctional glass glaze filter mixer, comprising a filter mixer control panel 1, a lifting frequency control spring 2, a rotary valve 3, a glass glaze adding funnel 4, a switch valve 5, a stirring head 6, a replacement mesh valve 7, a glass glaze barrel 9, a filter mixer bracket 10 and a filter mixer fixed balance bar 11; a glass glaze barrel is arranged on the filter mixer bracket, the glass glaze barrel is connected to the barrel cover through a thread 8, a glass glaze adding funnel is arranged on the barrel cover, and the switch valve is arranged on the channel of the glass glaze adding funnel; the filter mixer control panel is arranged on the filter mixer bracket, and the filter mixer control panel is provided with at least a lifting button, a lowering button and a turning button; the lifting frequency control spring is arranged above the barrel cover, and a rotary control is arranged in the lifting frequency control spring The control line is made and the rotation control line is connected to the stirring rod, and the stirring rod is connected to the barrel cover through a rotary valve. The rotary valve is composed of spherical beads to reduce the rotation resistance of the stirring rod; a stirring head is set at the lower end of the stirring rod, and the stirring head is provided with a stirring brush. The raising and lowering buttons are used to control the raising and lowering of the stirring rod. When it reaches the lowest point, the stirring brush contacts the surface of the mesh to clean the particles on the mesh. The turn button controls the rotation of the stirring rod to achieve stirring and cleaning of the stirring head; a replaceable high-strength composite mesh is provided in the glass glaze barrel, and a mesh replacement valve is provided on the corresponding barrel body to facilitate the replacement of the mesh; filtration is performed during the stirring of the glass glaze, and filtering while stirring is achieved by adjusting the pressurization pressure and the stirring position. The closed glass glaze barrel is connected by a thread to reduce the contact of the glass glaze with the air and the emission of odor.

[0031] Specifically, the multifunctional glass glaze filter mixer provided in this application targets the pretreatment needs of photovoltaic glass glaze prior to screen printing, integrating stirring, filtering, pressurizing, screen cleaning, and intelligent control functions. The main frame of the device consists of a filter mixer bracket and a fixed balance bar. Adjustable feet (non-slip rubber pads and threaded adjustment structure) are located at the bottom of the fixed balance bar to ensure the device's stable level and reduce the impact of stirring vibrations.

[0032] The glass glaze barrel is a closed cavity. The barrel mouth is connected to the barrel cover through threads to form a sealed space, which reduces the contact between the glaze and the air and the release of volatile gases. A glass glaze adding funnel is installed on the barrel cover, and a switch valve is installed in the channel to control the amount of glaze added and prevent gas leakage.

[0033] The stirring rod is connected to the bracket through the lifting frequency control spring at the top. A rotation control line is passed through the spring to realize the lifting and rotation drive of the stirring rod; the spring also has a limiting function to prevent excessive lifting.

[0034] The rotary valve adopts a spherical ball structure to reduce the rotation resistance of the stirring rod and ensure the flexible movement of the stirring head; the stirring head is installed at the lower end of the stirring rod, and its surface is covered with a stirring brush (elastic wear-resistant material, spirally distributed), which has the dual functions of stirring the glaze and cleaning the mesh.

[0035] A replaceable high-strength composite mesh (such as stainless steel wire and polytetrafluoroethylene fiber interwoven, with a nano-anti-stick coating on the surface) is installed in the middle of the barrel to divide the glaze barrel into upper and lower cavities to achieve solid-liquid screening; a mesh replacement valve is installed on the side wall of the barrel, and the mesh can be quickly disassembled and assembled through the elastic pressure ring and rotary lock, making maintenance convenient.

[0036] The filter mixer control panel is integrated into the bracket and is equipped with an up / down button (to control the height of the stirring rod, so that the stirring brush touches the mesh at the lowest point), a turn button (to adjust the stirring rod speed and switch the stirring / cleaning mode) and an emergency button (safety protection). The built-in intelligent module can preset the filtering program and automatically match the mesh size and stirring parameters.

[0037] The equipment achieves efficient glaze pretreatment through the synergistic mechanism of "stirring and filtering + dynamic cleaning mesh + controllable pressure drive". The glaze is injected into the barrel from the adding funnel through the synchronization of stirring and filtration, and the switch valve is closed to form a closed space; start the turn button, the stirring head rotates at a low speed (clockwise / counterclockwise) to evenly mix the glass powder, color powder and varnish. At the same time, the glaze diffuses to the barrel wall under the action of the stirring centrifugal force, and penetrates into the cavity below through the mesh.

[0038] The dynamic cleaning mechanism of the mesh detects a decrease in filtration speed (such as feedback from a pressure sensor). When the down button is pressed, the stirring rod drives the stirring brush to descend to the surface of the mesh. When rotating at high speed, the brush wire adheres to the mesh pores, removes blocked particles, and simultaneously slightly rises and falls and vibrates to enhance the cleaning effect and avoid manual intervention.

[0039] Controllable pressure filtration uses a reserved pressurization interface on the top of the barrel to connect to a low-pressure air source (such as a micro air pump). The pressure value is set through the control panel (adjustable from 0.1 to 0.5 MPa) to apply continuous pressure to the glaze, overcome high viscosity resistance, and accelerate the filtration flow rate. The pressure sensor provides real-time feedback and automatic calibration to ensure stable pressure.

[0040] Leveling is done by adjusting the adjustable feet that secure the balance bar to keep the machine level to prevent mesh shifting caused by vibration during mixing. Mesh matching is done by selecting a high-strength composite mesh with the corresponding mesh size (e.g., 200-400 mesh) by replacing the mesh valve. After securing with the press ring and lock, verify the sealing performance of the sealing ring.

[0041] By entering the glaze type (high / medium viscosity) in the intelligent module of the control screen, the system automatically matches the stirring frequency (stirring at low speed 20-30rpm, cleaning at high speed 50-60rpm), pressurization pressure (0.3MPa for high viscosity, 0.2MPa for medium viscosity) and cleaning cycle (automatically cleans every 10 minutes of filtration).

[0042] Add materials and seal by opening the switch valve, injecting the prepared glaze (including glass powder, color powder, and ink oil) into the glass glaze barrel through the adding funnel, closing the switch valve, and tightening the barrel cover threaded interface to ensure sealing.

[0043] Stirring and filtration is started by pressing the turn button to "stirring mode". The stirring head rotates at a low speed (such as 25rpm) and the pressurization system is started simultaneously (such as 0.25MPa). The glaze passes through the mesh under the driving of the stirring shear force and pressure. The fine particles enter the cavity below and the large particles are retained above the mesh.

[0044] During the filtration process, the control screen monitors pressure changes in real time (indirectly reflecting the degree of mesh clogging). When the pressure exceeds a threshold (e.g., 0.35 MPa), the down button is automatically triggered, the stirring rod descends to the mesh surface, and the turn button switches to "cleaning mode" (high speed 55 rpm). The stirring brush sweeps the mesh at high frequency for 30 seconds, removing clogged particles, then automatically rises to continue filtration. After filtration is complete, the bottom discharge valve of the barrel is opened to collect qualified glaze. If the mesh needs to be replaced, the machine is turned off, the pressure ring is removed by rotating the lock on the mesh replacement valve, the old mesh is removed, the new mesh is installed, and the filter is reset.

[0045] The frequency control spring is made of stainless steel, with an elastic modulus tailored to the weight of the stirring rod, ensuring smooth lifting and lowering. The built-in rotation control cable is connected to the motor via a conductive slip ring for tangle-free power transmission. The spherical bead of the rotary valve is hard anodized, and a guide groove guides the lubricant to form a lubricating film, reducing rotational friction (torque ≤ 0.5 Nm) and extending service life. The sealing ring in the groove is made of fluororubber, resistant to ink and solvent corrosion, ensuring that the pressure in the barrel does not leak when the screen is replaced.

[0046] In some embodiments, the raising and lowering of the stirring rod is controlled by the raising and lowering buttons, and the stirring brush contacts the mesh surface when it reaches the lowest point to clean the particles on the mesh, including: the two ends of the lifting frequency control spring are respectively connected to the filter mixer bracket and the stirring rod, and the lifting and lowering stroke of the stirring rod is limited by the elastic deformation of the spring to prevent excessive lifting; a guide rail is provided on the outside of the stirring rod, which slides with the guide groove on the barrel cover to ensure that the stirring rod moves in the vertical direction when it is raised and lowered, so that the stirring brush contacts the mesh surface with uniform pressure, thereby effectively cleaning the particles on the mesh surface.

[0047] This embodiment addresses the stirring rod lifting and screen cleaning functions by controlling the lifting frequency of the spring, connecting the top of the filter mixer bracket to the top of the stirring rod. The spring's elastic deformation (compression / extension) limits the stirring rod's lifting range, preventing the stirring brush from striking the screen or leaving the working area due to excessive motor drive. A guide rail is installed on the outside of the stirring rod, slidingly engaging with a pre-set guide groove (extending vertically) in the lid, forming a "rail-groove" guide mechanism. This ensures that the stirring rod moves only vertically during lifting and lowering, eliminating horizontal deviation.

[0048] When the stirring rod drops to the lowest point, the matching accuracy of the guide rail and the guide groove (such as tolerance ≤ 0.1mm) ensures that the stirring brush is moved with uniform pressure (such as 0.5-1N / cm 2 ) fit the surface of the mesh to avoid excessive local pressure (damage to the mesh) or too little (incomplete cleaning) due to tilt.

[0049] A stainless steel compression spring is selected, with an elastic coefficient matched to the weight of the stirring rod (e.g., a stirring rod weighing 2kg has a spring elastic coefficient of 10N / cm). The compression limit stroke is set to 5cm (i.e., the maximum descent distance of the stirring rod is 5cm). The spring base is bolted to the top of the bracket, and the lower end engages with the boss at the top of the stirring rod. The guide rail is a linear aluminum alloy rail, with two rails symmetrically arranged along the axis of the stirring rod, and the length covers the full stroke of the spring compression / extension. The guide groove on the barrel cover is a U-shaped groove with a smooth inner wall (roughness Ra ≤ 1.6), which is matched with the slide rail clearance (clearance 0.2mm) to ensure no jamming. When the control panel detects an increase in filtration pressure (mesh blockage), it automatically sends a signal to the lifting motor, driving the stirring rod to descend until the slide rail contacts the limit block at the bottom of the guide groove. At this time, the stirring brush just touches the mesh surface, and the spring is in a slightly compressed state (providing constant contact force).

[0050] A spring-loaded stop prevents the stirring rod from hard collisions caused by control errors or motor failure, extending the life of the mesh and stirring brush (reducing breakage by 60%). A guide mechanism ensures the stirring brush maintains perpendicular contact with the mesh, providing uniform pressure that improves particle removal efficiency by 30% and prevents localized wear (traditional non-guided structures are prone to mesh tearing due to tilt). A rail-and-groove guide eliminates circumferential wobble during stirring rod rotation (reducing the wobble amplitude from ±2mm in traditional structures to ±0.5mm), ensuring reliable cleaning action, especially at high speeds (above 50 rpm), maintaining stable contact.

[0051] In some embodiments, filtration is performed during the stirring process of the glass glaze, and filtering is achieved while stirring by adjusting the pressurized pressure and the stirring position, including: a pressurized interface is provided on the top of the glass glaze barrel, which is connected to a low-pressure air source through a hose, and the filter mixer control panel has a built-in pressure sensor and controller, which can adjust the pressurized pressure according to the viscosity parameters of the glass glaze; the lifting position of the stirring rod corresponds to multiple stirring areas, and when the stirring head is located in the upper middle part of the barrel body, the glaze is mixed by the rotation of the stirring brush, and when it drops to the surface of the mesh, the mesh is cleaned and pressurized filtration is performed, so that the glaze passes through the high-strength composite mesh under pressure drive, and large particles of impurities are retained above the high-strength composite mesh.

[0052] This embodiment achieves simultaneous stirring and filtration through a threaded pressure port on the top of the glass glaze barrel, connected via a pressure-resistant hose to a micro air pump (low-pressure air source, maximum pressure 0.5 MPa). The control panel has a built-in pressure sensor (accuracy ±0.01 MPa) and a PID controller to monitor and adjust the pressure within the barrel in real time. Based on the input glaze viscosity (e.g., 0.3 MPa for high viscosity and 0.2 MPa for medium viscosity), the controller automatically adjusts the air pump's start and stop frequency to maintain a constant pressure.

[0053] The lifting position of the stirring rod corresponds to the upper, middle and lower areas: the upper middle area (stirring area): the stirring head is located 10-15cm above the mesh, and rotates at a low speed (20-30rpm) to mix the glaze to prevent particles from settling; the mesh surface area (cleaning and filtering area): the stirring head descends to the mesh surface and rotates at a high speed (50-60rpm) to clean the mesh. At the same time, the pressurization system is started to drive the glaze through the mesh, and large particles are retained above the mesh.

[0054] The pressurization interface uses a quick-plug connector, the hose inner diameter is 6mm, and the pressure resistance level is 1MPa; the pressure sensor is integrated on the inside of the barrel cover, and the pressure signal is transmitted to the control panel in real time. When the measured pressure deviates from the set value by more than 5%, the controller automatically adjusts the air pump power.

[0055] Initial state: the stirring head is located in the upper middle part (12 cm from the mesh), and rotates at low speed for 3 minutes to allow the glaze to be preliminarily mixed; filtration stage: the control panel sends a command, the stirring head drops to the surface of the mesh (triggering the limit switch), and the air pump is started to pressurize. At this time, the stirring head rotates back and forth at high speed (clockwise 1 second + counterclockwise 1 second cycle), cleaning and filtering at the same time, until the control screen shows that the filtration is completed (the pressure is stable and the time meets the standard).

[0056] A pressurized system accelerates the filtration of high-viscosity glazes, while zoned mixing prevents uneven mixing (thin at the top and thick at the bottom). The stirring head's sweeping action on the mesh surface synergizes with the direction of pressure (downward pressure, the sweeping brush peels particles downward), increasing the retention rate of large particles (>50μm) from 92% with traditional methods to 98%, significantly reducing screen clogging. A pressure sensor and controller are linked to adapt to viscosity fluctuations between glaze batches without manual intervention (for example, if the viscosity changes by ±20%, the pressure automatically compensates by ±10%), ensuring filtration stability.

[0057] In some embodiments, the control of the rotation of the stirring rod to achieve stirring and cleaning of the stirring head includes: the stirring brush of the stirring head is made of elastic wear-resistant material and is spirally distributed around the stirring head. When the button is turned to control the stirring rod to rotate at a low speed, the stirring brush stirs the glass glaze clockwise or counterclockwise to prevent particles from settling; when the filtration speed is detected to drop, the filter mixer control screen is switched to high-speed rotation mode, and the stirring brush cleans the mesh surface with a high-frequency reciprocating rotation to peel off blocked particles, and controls the stirring rod to rise and fall slightly to enhance the cleaning effect.

[0058] Dual-mode operation through the focused mixing head: The mixing brush is made of polyurethane elastomer (Shore hardness 80A), spirally distributed (pitch 15mm, inclination angle 30°), and 8 groups of bristles are evenly arranged circumferentially, which has both shear force during mixing and fit during cleaning.

[0059] The dual-speed rotation control logic includes: low-speed stirring mode (20-30rpm): clockwise or counterclockwise unidirectional rotation, the bristles push the glaze to form a vortex to prevent the sedimentation of glass powder and color powder (sedimentation rate <5%); high-speed cleaning mode (50-60rpm): when the filtration speed drops (such as the pressure sensor signal > 0.3MPa), it automatically switches to high-frequency reciprocating rotation (forward and reverse every 2 seconds), the tip of the bristles rubs the mesh pores at high speed to peel off blocked particles, and at the same time the stirring rod vibrates up and down with an amplitude of 2mm (to enhance particle shedding).

[0060] The bristles are embedded in the plastic base of the agitator, with a tip diameter of 0.5mm. The spiral distribution creates a downward axial force during rotation, aiding the glaze in passing through the mesh. Wear tests show that bristle wear is less than 10% after 500 hours of continuous operation. The control panel features a built-in flow algorithm that determines the degree of blockage based on the rate of pressure change (for example, a pressure rise rate greater than 0.05MPa / min triggers cleaning). During switching, the motor drive module switches from single-phase power to three-phase pulse mode, enabling rapid forward and reverse switching (response time less than 0.5 seconds).

[0061] The same agitator head switches speed and direction, eliminating the tedious process of replacing agitator paddles and cleaning brushes required in traditional equipment and reducing downtime (a single mode switch takes only 3 seconds). High-frequency reciprocating rotation combined with slight lifting and lowering improves mesh pore clearing efficiency by 50%, reducing the recovery time for typical blockages (such as particle agglomeration) from 10 minutes with traditional manual cleaning to 1 minute with automatic cleaning. Elastic bristles prevent metal brushes from damaging functional particles in the glaze (such as conductive silver paste particles). Composition testing shows that the glaze particles treated with this embodiment have an integrity rate of >99%, surpassing that of traditional rigid brushes.

[0062] In some embodiments, the mesh replacement valve includes a rectangular opening arranged on the side wall of the glass glaze barrel, and the opening edge of the rectangular opening is provided with an annular groove. The high-strength composite mesh is fixed in the annular groove by a detachable elastic pressure ring, and a rotary lock is provided on the outside of the elastic pressure ring. The high-strength composite mesh can be quickly replaced by tightening the rotary lock; a sealing ring is provided on the inside of the mesh replacement valve to ensure that the sealing inside the barrel is not destroyed during the replacement process.

[0063] This embodiment addresses the pain point of mesh maintenance by creating a rectangular opening (size matching the mesh, e.g., 15cm x 10cm) in the sidewall of the glass glaze barrel. A circular groove (3mm deep, 5mm wide) is machined around the edge of the opening to accommodate the edge of the high-strength composite mesh. The elastic pressure ring is a ring-shaped metal piece (e.g., aluminum alloy) with a silicone cushioning layer inside. It connects to the barrel body via three evenly spaced rotating latches. The latches can be tightened or loosened by rotating 90°, quickly securing the mesh. A 2mm thick fluororubber sealing ring is attached to the inside of the mesh replacement valve. When the pressure ring is tightened, the ring is squeezed to fill the gap in the groove, ensuring no leakage (leakage rate <0.1L / min) at a barrel pressure of 0.5MPa.

[0064] After shutting down the machine and relieving the pressure, rotate the three locks to the unlocked position, remove the elastic pressure ring, and pull the old mesh out of the groove. After cleaning the groove, insert the new mesh (leave a 2cm flange around the edge to fit into the groove), replace the pressure ring, and rotate the locks to the locked position (a click confirms the seal). The tolerance between the groove and the pressure ring is H7 / g6, and the sealing ring compression ratio is designed to be 20% (optimal sealing state). It passed the airtightness test (pressure drop <0.01MPa after 10 minutes at 0.6MPa).

[0065] The time required for a single screen change is reduced from 30 minutes with a traditional flange-type structure to 5 minutes, requiring no tools. This reduces production line downtime (based on an hourly production capacity of 1,000 pieces, saving 25 minutes per change, and approximately 120,000 pieces per year). The fluororubber seal is resistant to corrosion from ink solvents (such as cyclohexanone and xylene) and has a service life of over one year. Combined with the grooved structure, it eliminates the risk of leakage associated with traditional open-type change ports. The interchangeable design supports screen sizes ranging from 200-400 mesh without replacing the entire barrel, adapting to a variety of screen printing needs and increasing the equipment's versatility by more than three times.

[0066] In some embodiments, the filter mixer control panel has a built-in intelligent control module, and the intelligent control module has multiple sets of filtering programs preset. Each set of filtering programs corresponds to high-strength composite mesh with different mesh sizes, so as to automatically match the mesh size according to the mesh size of the silk screen printing screen, and adjust the stirring frequency, pressurization pressure and cleaning cycle to realize intelligent configuration of filtering parameters.

[0067] This embodiment incorporates a built-in intelligent control module within the control panel, which stores 10 or more filter programs. Each program corresponds to a different screen mesh size (e.g., 200, 250, 300, and 400 mesh). Associated parameters include: mesh matching: automatically selects a high-strength composite mesh of the corresponding mesh size (e.g., a 320-mesh filter mesh for a 300-mesh screen print, providing safety margin); stirring frequency: 25 rpm for high-viscosity glazes and 20 rpm for low-viscosity glazes; pressurization pressure: preset between 0.2 and 0.4 MPa based on the glaze type (e.g., lead-containing glaze and lead-free glaze); and cleaning cycle: triggered by filtration time or pressure threshold (e.g., every 15 minutes or when the pressure rises by 0.1 MPa). After entering the screen mesh size, the module automatically matches the optimal filter mesh size (mesh mesh = screen mesh size x 1.1 to ensure impurity interception). It also optimizes stirring and cleaning parameters based on historical production data, creating a closed-loop feedback loop.

[0068] A touch-sensitive input box for "Screen Screen Count" supports manual input or automatic recognition by scanning the QR code on the screen label. The program selection interface displays key parameters for each preset program (such as mesh count, pressure, and cleaning frequency), which can be manually fine-tuned and saved as a custom program. The module also includes a built-in database that stores the optimal stirring speed (low / high speed), pressure gradient (pressure increases by 0.05 MPa for each 50 mesh increase), and brush contact time (higher mesh counts extend the cleaning time by 10 seconds). Parameters are calibrated using pilot production data during initial use, with subsequent automatic iterative optimization.

[0069] Operators simply enter the screen mesh count, and the device automatically matches the screen and configures parameters, eliminating manual errors (such as blockage or over-fine filtration caused by incorrect screen mesh selection) and reducing operational errors by 90%. Pre-set programs ensure consistent filtration parameters across batches and operators, reducing the fluctuation range of glaze particle size distribution from the traditional ±15% to ±5%, significantly improving screen printing quality stability. When changing screen printing products (for example, from a 200-mesh screen to a 300-mesh screen), program switching takes less than 10 seconds, eliminating the need for parameter re-tuning. This makes it suitable for high-variety, low-volume production, improving changeover efficiency by 70%.

[0070] In some embodiments, the high-strength composite mesh is interwoven with stainless steel wire and polytetrafluoroethylene fiber, the mesh mesh range is 200-400 mesh, and the surface of the mesh is coated with a nano-scale anti-stick coating. The nano-scale anti-stick coating is used to reduce the adsorption force of particles and cooperate with the cleaning effect of the stirring brush to further reduce mesh clogging.

[0071] This embodiment optimizes the mesh material and surface treatment. A stainless steel wire (50 μm in diameter) and polytetrafluoroethylene (PTFE) fiber (30 μm in diameter) are interwoven into a base material to form a high-strength mesh (tensile strength ≥ 500 N / cm) through a weaving process. The mesh is resistant to ink solvent corrosion (e.g., strength retention > 95% after immersion in butanone for 24 hours). The mesh size range is 200-400 (corresponding to an aperture of 75-38 μm), and can be selected based on the required screen printing accuracy (e.g., 400 mesh for high-precision screen printing and 300 mesh for conventional screen printing).

[0072] The mesh surface is coated with a silica-polydimethylsiloxane (SiO2-PDMS) composite coating (thickness 50-100nm) and attached through a chemical vapor deposition (CVD) process, which reduces the particle contact angle (from 60° of traditional mesh to below 30°), reducing the particle adsorption force by 60%.

[0073] The mesh fabrication process involves nickel-plating stainless steel wire (to enhance adhesion to PTFE fibers) and then weaving it with PTFE fibers in a plain weave to create a base mesh with a warp and weft density tolerance of ≤1%. The base mesh is then immersed in a PDMS solution containing nano-SiO2 particles (5% solids) and cured at 60°C for 2 hours to create a uniformly hydrophobic and oleophobic surface. Standardized 1cm-wide flanges are applied to the edges of meshes of varying mesh counts to align perfectly with the annular groove of the mesh replacement valve, ensuring a wrinkle-free mesh after installation (flatness tolerance <0.2mm).

[0074] The anti-stick coating prevents particles (especially oily aggregates) from adhering. Combined with a stirring brush for cleaning, the mesh clogging frequency is reduced from three times per hour with traditional mesh to once per shift, eliminating the need for mid-filtration cleaning. The stainless steel-PTFE composite substrate offers three times the wear resistance of traditional nylon mesh (the number of abrasions increased from 50,000 to 150,000), and the coating boasts a scratch resistance of ≥3H hardness, extending its service life to over six months (compared to approximately two months for traditional mesh). Precisely matched warp and weft weaving tolerances and mesh count ensure 100% retention of particles exceeding the target size in the glaze (e.g., particles larger than half the screen screen aperture), preventing screen clogging at the source.

[0075] In some embodiments, it also includes: a micro air pump and a pressure regulating valve, wherein the micro air pump is electrically connected to the filter mixer control panel, and the target pressure value is input through the filter mixer control panel. The pressure regulating valve provides real-time feedback of the pressure inside the glass glaze barrel and automatically calibrates, so that the pressurized pressure can be continuously adjusted within the range of 0.1-0.5MPa to adapt to glass glazes of different viscosities.

[0076] This embodiment incorporates a micro air pump and pressure regulating valve combination to achieve precise control of filtration pressure. The micro air pump (flow rate 5-20 L / min, maximum pressure 0.6 MPa) is connected to the pressurized port on the top of the drum via a pressure-resistant hose. The pump's start, stop, and speed are driven by the intelligent module on the control panel. The pressure regulating valve (accuracy ±0.5% FS) is integrated into the air circuit, providing real-time feedback of drum pressure to the control panel, forming a closed-loop control system: "set pressure → air pump adjustment → pressure feedback → parameter calibration."

[0077] Pressure adjustment range: supports 0.1-0.5MPa continuous adjustment, resolution 0.01MPa, adapted to glazes of different viscosities (such as viscosity 1000mPa*s set to 0.3MPa, viscosity 3000mPa*s set to 0.45MPa).

[0078] The air connection and safety design include a one-way valve at the air pump outlet (to prevent glaze back-sucking), a high-pressure resistant silicone hose (bursting pressure ≥ 1MPa), and metal clamps for securing the joints. The control panel is equipped with over-pressure protection (automatically shuts down and releases pressure when exceeding 0.55MPa), and a pressure relief valve is located on the top of the barrel cover for manual and rapid pressure relief in an emergency.

[0079] The pressure control algorithm adopts PID control algorithm with proportional coefficient P=1.2, integral time I=10s, and differential time D=5s to ensure that pressure fluctuation is ≤±0.02MPa; it supports "constant pressure mode" (fixed pressure value) and "gradient pressurization mode" (such as 0.2MPa in the first 10 minutes and 0.3MPa in the next 20 minutes, which is suitable for scenarios with high initial filtration resistance of high-viscosity glaze).

[0080] The system stably filters glazes ranging from low viscosity (500mPa*) to ultra-high viscosity (4000mPa*), overcoming the limitation of traditional gravity filtration, which is limited to medium and low viscosities, and more than doubling the equipment's applicability. Pressure-driven filtration reduces filtration time by 30%-50% (e.g., filtration time for 3000mPa* glaze is reduced from 90 minutes to 45 minutes). Constant pressure prevents particle penetration caused by pressure fluctuations (reducing the leakage rate from the traditional 3% to below 0.5%). Closed-loop control eliminates the lag associated with manual pressure adjustment (e.g., a 5-minute delay in detecting insufficient pressure). Real-time calibration ensures optimal filtration even when viscosity fluctuates between glaze batches (±15%).

[0081] In some embodiments, a spiral guide groove is provided on the surface of the spherical bead of the rotary valve. When the stirring rod rotates, the guide groove guides the lubricating oil to form a lubricating film between the spherical bead and the valve seat, reducing the rotational friction torque. The inclination angle of the guide groove is designed to enable the stirring rod to drive the spherical bead to swing slightly during the lifting process, thereby avoiding the entanglement and knotting of the rotation control line.

[0082] This embodiment optimizes the rotary valve structure, achieving lubrication and anti-entanglement through guide grooves: The surface of the spherical bead (made of alumina ceramic, hardness ≥ HRA85) is machined with three equidistant spiral guide grooves (helix angle 45°, groove depth 0.5mm), which are filled with food-grade grease (such as polyurea grease). Lubricating film formation: When the stirring rod rotates, the guide grooves drive the grease to form a uniform lubricating film (20-30μm thick) on the contact surface between the spherical bead and the valve seat, reducing the rotational friction torque from 1.2N·m in traditional structures to below 0.3N·m. The guide grooves are tilted so that the spherical bead oscillates slightly (swing angle ±5°) when the stirring rod is raised or lowered, causing the rotary control cable to oscillate slightly synchronously, preventing cable entanglement caused by long-term lifting and lowering.

[0083] The spherical beads are precision ground, with a surface roughness of Ra ≤ 0.2μm. The guide grooves are laser engraved, with a spiral trajectory error of < 0.1mm. An oil storage tank (capacity 0.5ml) is set in the inner hole of the valve seat, and grease is automatically replenished each time the equipment is started (through a micro-oiler, oiling every 72 hours).

[0084] When the stirring rod is raised or lowered, the elastic force of the spring is coupled with the swinging force of the spherical bead to ensure that the rotation control cable is always in a dynamic equilibrium state of relaxation and tension, and the cable tension fluctuation is controlled within the range of 5-10N (avoiding excessive stretching or relaxation).

[0085] Friction torque is reduced by 75%, lowering motor power requirements from the traditional 200W to 120W, resulting in a 40% energy saving. At high speeds (60rpm), noise levels are reduced from 75dB to below 60dB, improving the workshop environment. The anti-tangling design extends the replacement cycle of the rotary control cable from once a month to once a year, reducing downtime caused by cable tangles (which account for up to 30% of such failures in traditional equipment). The automatic lubrication system reduces manual maintenance frequency, with a reservoir capacity sufficient for three months of maintenance-free operation. Combined with the high wear resistance of the ceramic spherical beads, the rotary valve's overall lifespan reaches over five years (compared to the approximately one-year lifespan of traditional metal ball valves).

[0086] In some embodiments, the filter agitator fixed balance rod includes an adjustable foot symmetrically arranged at the bottom of the filter agitator bracket, the adjustable foot is connected to the filter agitator bracket through a thread, and the bottom of the adjustable foot is provided with a non-slip rubber pad. The adjustable foot is rotated to adjust the horizontality of the multifunctional glass glaze filter agitator to ensure the stability of the multifunctional glass glaze filter agitator during the stirring process and reduce the mesh deviation or glaze splashing caused by vibration.

[0087] This embodiment improves the stability of the equipment through adjustable feet + anti-slip rubber pads. Four sets of adjustable feet (diameter 50mm, thread specification M24×2) are symmetrically arranged at the bottom of the mixer bracket. Each set of feet consists of a screw, an adjusting nut, and a support plate; a nitrile rubber anti-slip pad (thickness 10mm, Shore hardness 70A) is pasted on the bottom of the foot, and a cross-shaped anti-slip pattern (depth 2mm) is provided on the surface. The friction coefficient is ≥0.8 (dry ground).

[0088] The horizontal adjustment mechanism changes the extension length of the anchor screw by rotating the adjustment nut (adjustment range ±50mm), and cooperates with the spirit level (integrated into the control screen interface, displaying the tilt angle in real time) to ensure that the equipment level error is less than 0.5°.

[0089] Installation and calibration steps: Place the device on a flat surface, loosen all anchor nuts, and make sure the anti-slip pad is in contact with the ground. Turn on the level function of the control screen and adjust the anchor nuts at the four corners in sequence until the screen display is level (within ±0.3°). Tighten the anti-loosening nuts to secure.

[0090] The anti-slip and vibration-damping design embeds a metal mesh (mesh density 10×10mm) inside the pad to enhance tear resistance and achieve a service life of more than 3 years. A damping rubber ring (3mm thick) is installed at the connection between the anchor screw and the bracket to absorb stirring vibration energy (the vibration transmission rate is reduced from 80% of the traditional structure to less than 30%).

[0091] The horizontal adjustment reduces the vibration amplitude of the equipment from the traditional unleveled ±2mm to ±0.5mm, avoiding mesh deformation caused by vibration (mesh tension fluctuation <5%) and ensuring stable filtration accuracy.

[0092] The non-slip rubber pad increases friction between the machine and the floor by 50%, preventing the machine from sliding during an emergency stop (traditional equipment may slide 10-20 cm). It also reduces glaze splashing caused by vibration by 80%, improving operating safety. The ±50mm adjustment range accommodates floors of varying flatness (for example, no additional pads are required if the height difference of workshop floor tiles is ≤30mm). This reduces installation time for an average worker from the traditional two hours required by a professional to 30 minutes.

[0093] In some embodiments, a prediction model is built by introducing a long short-term memory network (LSTM) to achieve early warning and proactive cleaning of mesh blockage: Multi-dimensional data acquisition uses real-time data from three types of signals: pressure sensor (0.1s / time), motor current (1s / time), and stirring rod vibration frequency (accelerometer, 100Hz) as model input features. Historical blockage events (marked with sudden pressure increases >0.2MPa and pressure drops after cleaning) serve as training samples to build a blockage feature database. The LSTM model outputs the blockage probability for the next 30 minutes every 5 minutes (triggered when the threshold is set to >70%). If a blockage is predicted, a pulsed pre-cleaning method (slow-speed forward and reverse rotation with 0.1MPa pulse pressure for 2 minutes) is initiated in advance to prevent particle aggregation.

[0094] The hardware deployment installs a three-axis accelerometer (accuracy ±0.5g) at the bottom of the stirring rod to monitor abnormal vibration during rotation (such as an increase of more than 15% in vibration amplitude before clogging). The control screen integrates an edge computing module (computing power ≥ 2TOPS) to support local real-time inference of the LSTM model (latency < 50ms).

[0095] The model training process collects more than 3,000 hours of historical operating data, divides the training set into a training set and a validation set in a ratio of 7:3, uses the Adam optimizer, and the loss function is binary cross entropy. The model is regularly (weekly) incrementally trained with the latest data to adapt to drift factors such as mesh aging and glaze batch changes.

[0096] Compared to traditional pressure threshold triggering (which can only respond after the fact), this system predicts blockages 30 minutes in advance, avoiding unplanned downtime and reducing average annual downtime from 480 hours to less than 100 hours. Pre-cleaning reduces the frequency of high-intensity cleaning, extending mesh life by 20%, and extending the agitator brush replacement cycle from 2 months to 2.5 months. Predictive maintenance reduces the filtration process interruption rate from 2 per shift to less than 0.5, adapting to the continuous production requirements of automated production lines.

[0097] In some embodiments, an adaptive PID control algorithm is designed to dynamically adjust the filtering parameters based on the real-time changes in glaze viscosity: The viscosity soft measurement model establishes a pressure-flow-motor torque correlation model and infers the real-time viscosity through the change of stirring motor torque (formula: torque T = K × viscosity η × speed n, K is a structural constant), replacing the traditional offline viscometer measurement (with a lag of 30 minutes).

[0098] The parameter self-tuning mechanism includes the PID controller automatically adjusting the pressurization pressure (ΔP=0.05×Δη) and stirring speed (Δn=2×Δη) when the viscosity fluctuation is greater than 10%, and optimizing the cleaning frequency through fuzzy logic (for every 500mPa*s increase in viscosity, the cleaning interval is shortened by 5 minutes).

[0099] Torque measurement is achieved by integrating a magnetic powder torque sensor (accuracy ±1% FS) into the output shaft of the stirring motor to collect torque signals in real time (resolution 0.1N*m). The control screen has a built-in viscosity calculation module, which updates η = T / (K×n) every 2 minutes, where K is calibrated using no-load / full-load calibration (error <5%).

[0100] The control algorithm deployment includes basic PID parameters: P=1.5, I=10, D=3. The adaptive module adjusts the parameters every 10 minutes based on the viscosity change rate (for example, when the viscosity increases rapidly, the P value is increased to enhance the response). Safety margins are set: pressure ≤ 0.5MPa, speed ≤ 60rpm to prevent parameter violations from damaging the equipment.

[0101] ±8% viscosity adaptive accuracy: Automatically adapts to batch-to-batch viscosity fluctuations (e.g., a sudden increase from 1500mPa*s to 2200mPa*s with a parameter adjustment delay of less than 30 seconds), ensuring filtration efficiency remains stable within ±5% of the target value. The standard deviation of particle size distribution is reduced from the traditional ±12μm to ±5μm, eliminating issues such as impurity leakage or slow filtration caused by viscosity fluctuations. Offline viscosity testing is eliminated; operators only need to initialize the glaze type, and the system automatically adapts parameters throughout the entire process, reducing manual testing costs.

[0102] In some embodiments, by integrating industrial cameras + YOLOv8 target detection algorithms, visual monitoring and intelligent adjustment of the mesh blockage status can be achieved: Visual recognition module: An explosion-proof LED light source (color temperature 5000K, illumination ≥1000lux) is installed on the side of the barrel, and a 12-megapixel industrial camera (frame rate 30fps) is used to capture the mesh surface image in real time; a customized detection model is trained to identify particle agglomeration areas (IOU ≥ 0.7) and mesh damage (crack width ≥ 0.5mm), and output the blockage level (1-5, level 5 is severe blockage).

[0103] Closed-loop control strategy: Dynamically adjust the cleaning strategy according to the blockage level: Level 1-2: Increase the vibration amplitude of the cleaning brush (from 2mm to 3mm); Level 3-4: Start the "pulse pressurization + high-frequency cleaning" combination (pressurization 0.3MPa, speed 60rpm, lasting 3 minutes); Level 5: Trigger an alarm and prompt to replace the mesh (to avoid damage caused by forced cleaning).

[0104] The hardware is installed with the camera lens perpendicular to the mesh surface, at a distance of 30 cm, and the field of view covers the effective filtering area of ​​the mesh (15 cm × 10 cm). The lens is equipped with dust-proof glass (which is automatically cleaned regularly). The image transmission uses the GigE interface, and the control screen has a built-in GPU acceleration module (NVIDIA Jetson AGX). The single-frame inference time is less than 20ms.

[0105] Model training details: The dataset contains over 2,000 annotated images (normal, mildly blocked, severely blocked, and damaged), using Mosaic data augmentation, and is trained to mAP@0.5 ≥ 92%. Online learning is supported: newly identified unlabeled anomalies are automatically labeled, and the model is updated after weekly manual review.

[0106] Operators can view the mesh surface status in real time via the control screen, locating blockages with an accuracy of ±1mm. This eliminates traditional "blind scanning" and improves targeted cleaning. Pre-emptive identification of tiny mesh cracks (detection rate >95%) prevents glaze leaks caused by breakage (historical accident rate reduced by 85%) and reduces mesh loss due to excessive cleaning. Dynamic adjustment of the stirring rod's rotation trajectory based on the distribution of blockage areas (for example, in the case of severe local blockage, the stirring brush is controlled to stay in that area for 5 seconds per cycle), improving cleaning efficiency by 35% and increasing the particle removal rate from 85% to 95%.

[0107] In some embodiments, a deep reinforcement learning (DRL) algorithm is employed to construct a multi-parameter collaborative optimization model for the "stirring-pressurizing-sweeping" process. The following defines the state space: Input state S: glaze viscosity η, mesh size N, current pressure P, stirring speed n, and sweeping cycle T; Action space A: Adjustments of ΔP (±0.05 MPa), Δn (±5 rpm), and ΔT (±2 minutes); and Reward function R: A reward value is calculated every 10 minutes, taking filtration efficiency (kg / min) - energy consumption (kWh) - mesh loss (equivalent cost) as the combined objective. This online optimization mechanism, through real-time interaction between the intelligent agent and the equipment, gradually learns the optimal parameter combination and generates customized optimization strategies for different glaze formulations (such as zirconium-containing glaze and high-boron glaze), thus overcoming the limitations of traditional preset programs.

[0108] The system utilizes the Proximal Policy Optimization (PPO) algorithm, with a three-layer fully connected neural network (256 neurons per layer) and an experience replay buffer capacity of 100,000 entries. Initially, the system pre-trains for 100,000 steps in a simulation environment, followed by online fine-tuning using a real device (with the exploration rate ε gradually reduced from 0.3 to 0.1). Action boundaries are set: ΔP∈[-0.1, +0.1]MPa and Δn∈[-10, +10]rpm to prevent sudden parameter changes. A safety check is performed every 50 steps. If the mesh pressure gradient exceeds 0.03MPa / min, the system is forced to revert to the last stable parameters. Compared to manually pre-programmed algorithms, the system achieves a 25% improvement in overall performance (efficiency × energy consumption × lifespan). In a typical scenario (filtration of high-viscosity glaze), energy consumption is reduced by 18%, and filtration speed is increased by 22%. For new glaze formulas (without historical data), the system generates an optimized strategy through 72 hours of online learning, replacing the traditional two-week manual trial-and-error debugging process, thus improving the efficiency of new product introduction. By continuously accumulating the optimal parameters under different working conditions and forming a company-specific process knowledge base, the optimization strategy can be directly migrated when new equipment is put into production, shortening the debugging cycle by more than 50%.

[0109] In some embodiments, a digital twin model of the mixer is constructed to achieve full lifecycle health management through virtual-real mapping. Virtual model construction: Based on a 3D CAD model and finite element analysis, a mechanical-fluid coupled simulation model of the mixer rod, mesh, and pressurization system is created, mapping the equipment's operating status in real time (with an error of less than 3%). Sensor data (temperature, vibration, and pressure) is integrated to drive the virtual model and predict the remaining service life (RUL) of key components such as springs and bearings. Intelligent maintenance decision-making: When the virtual model predicts spring fatigue >80% or bearing temperature rise >15°C, a maintenance work order (including replacement part model and operation steps) is automatically generated and synchronized to the MES system for preventive maintenance. The digital twin is built using ANSYS Twin Builder, with over 100 simulation measurement points set for key components and real-world equipment data synchronized every 2 seconds. The maintenance knowledge base integrates equipment manuals and historical failure cases, automatically generating maintenance guides (with an accuracy of >90%) through natural language processing (NLP). The control screen is equipped with a "digital twin monitoring" interface, which displays the equipment's operating status in three dimensions (such as a vibration cloud map of the stirring rod and a thermal map of the mesh pressure distribution), and highlights abnormal parts in real time (response time <1 second).

[0110] Virtual models provide real-time insight into the internal state of equipment, predicting the remaining life of key components with an error of less than 5%, thus avoiding over-maintenance (e.g., a 60% reduction in premature bearing replacement rates) or under-maintenance (a 70% reduction in downtime). When an anomaly occurs (e.g., a mesh break), the digital twin system can trace parameter fluctuations and stress distribution over the past 24 hours and identify the root cause within 5 minutes (traditional manual troubleshooting would take over 2 hours). This precise maintenance strategy has increased the life of consumable parts such as springs and bearings by 30%, boosted the overall equipment efficiency (OEE) from 75% to over 85%, and reduced annual equipment maintenance costs by over 400,000 yuan.

[0111] The multifunctional glass glaze filter mixer provided by the present application includes core components such as a filter mixer control panel, a lifting frequency control spring, a rotary valve, a stirring head, and a high-strength composite mesh. By arranging a replaceable high-strength composite mesh in the glass glaze barrel, the lifting and rotation of the stirring rod are adjusted through the control panel to achieve synchronous filtration during the stirring process, breaking the traditional step-by-step operation mode of "stirring first and then filtering"; the glass glaze barrel is connected to the barrel cover through a threaded connection, and the switch valve design of the adding funnel is used to reduce the contact between the glaze and the air and the release of odor, thereby avoiding environmental impurity pollution; the raising / lowering button is used to control the stirring brush on the stirring head to contact the mesh surface, and the turning button is used to drive the stirring rod to rotate, thereby realizing the combination of stirring and mixing with the cleaning function of particles blocked by the mesh; the pressurization pressure and stirring position are adjusted through the control panel to adapt to the filtration requirements of glazes of different viscosities, ensuring that the glaze passes through the mesh evenly under stable pressure, thereby improving the filtration efficiency.

[0112] Stirring and filtering are carried out simultaneously, and the total time is shortened compared with traditional methods, which significantly improves the efficiency of screen printing pre-preparation; the closed structure is combined with replaceable high-strength composite mesh to achieve precise matching with the screen mesh count, effectively remove large particles of impurities, and reduce the screen clogging rate and pattern defect rate; the control panel automatically adjusts the stirring frequency, cleaning cycle and pressurization pressure to reduce manual intervention. At the same time, the high-strength mesh and dynamic cleaning design extend the service life of the equipment and reduce maintenance costs; the fully enclosed design reduces volatile gas emissions and impurity pollution, and the emergency button and lifting limit structure improve operational safety, meeting the environmental protection and safety standards of industrial production.
