[0014] Step 2, high-speed dispersion, after the material is fully wetted, control the telescopic device to drive the movable column to move downward, when the movable column moves downward, the inner spline ring moves to the groove position, so that the stirring structure loses the driving and is static under the action of gravity, at the same time, the bowl-shaped dispersion block fixed on the movable column also descends, no longer extruding the triangular extrusion block fixed on the extension rod, under the tension of the third extrusion spring, the sliding rod drives the extension rod to contract inward, so that the extrusion part at the end of the extension rod clamps the outside of the static connecting ring to fix it, then, increase the rotating speed of the servo motor, the movable column drives the inclined blade turbine paddle to rotate through the mounting ring, generates radial flow, and the fluid moves outward under the action of centrifugal force, collides with the static flow guide plate and is converted into axial flow circulating up and down, so as to break the vortex, make the material in the tank form convection in the longitudinal direction, realize high-efficiency dispersion, shearing and homogenization, and ensure that the product reaches the required fineness and uniformity;

[0016] Step 4, after the completion of dispersion homogenization and the inspection, the product is discharged by opening the discharge valve at the bottom of the processing tank, and then the cleaning is carried out: the telescopic device continues to push the movable column downward, so that the first mounting block in the mounting ring slides downward against the force of the first extrusion spring, when the first mounting block moves downward, the extension rod is pushed outward by the rotating rod on the side of the first mounting block until the end of the extension rod contacts the inner wall of the processing tank, at the same time, the positioning ball in the mounting ring is embedded into the positioning cavity on the side of the first mounting block under the action of the second extrusion spring, so that the transmission connection between the movable column and the rotating block is realized, the servo motor is started to rotate, the movable column drives the rotating block and the extension rod to rotate together through the butt joint structure, and the cleaning liquid is sprayed through the feeding port, the extension rod rotating scrapes and cleans the residual viscous material attached to the tank wall, and the cleaning waste water is discharged from the bottom, so that the cleaning is completed and the processing tank is ready for the next use.

[0017] Compared with the prior art, the beneficial effects that can be achieved by the present application are:

[0018] 1、The present application realizes efficient dispersion and mixing by the cooperation of the inclined blade turbine paddle and the flow guide plate, avoids the generation of air bubbles, the inclined blade turbine paddle is fixed on the mounting ring at the bottom of the movable column, and strong radial flow is generated when rotating at high speed, so that the fluid moves outward under the action of centrifugal force, and the flow guide plate is fixed outside the material stirring structure, and the radial flow is converted into axial flow circulating up and down through the flow guide plate, so that strong convection mixing is formed, this structure cooperation breaks the common circumferential flow stagnation area in traditional stirring, so that the material in the tank fully circulates in the longitudinal direction, and is suitable for the dispersion of high-viscosity flow leveling agent, and at the same time, the slow initial rotation is transmitted through the first spline groove and the inner spline ring to avoid the air being rolled in when feeding at high speed, effectively reduces the generation of air bubbles, and improves the stability and uniformity of the product.

[0019] 2、The present application realizes convenient sampling and process monitoring through the linkage of the sliding column, the guide hole and the infiltration groove, the sliding column moves up and down in the second sliding groove, when being lifted to a position above the infiltration groove, the liquid in the tank enters the second sliding groove through the infiltration groove, when being pressed down, the sliding column closes the infiltration groove, and the liquid in the groove can only be discharged upward through the guide hole and guided to the external receiving container through the connecting rod, so that the rapid closed sampling of the material during production is realized without stopping or opening the main tank cover, external pollution and material loss are avoided, and the mixing degree and reaction state are monitored in real time, so that the production quality is detected.

[0020] 3. This invention achieves switching between mixing and cleaning modes through the cooperation of the dispersing block, the extension rod, and the extrusion block. The dispersing block is fixed to the outside of the movable column. In the initial position, its bowl-shaped structure extrudes the extrusion block, causing the extension rod to detach from the connecting ring. When the movable column moves down, the dispersing block detaches from the extrusion block, and the third extrusion spring pulls the sliding rod and the extension rod inward to clamp the connecting ring, fixing the material feeding and mixing structure and preventing it from rotating with high-speed mixing. During cleaning, the movable column continues to press down, and the rotating rod in the docking structure pushes the extension rod outward to contact the tank wall. As the rotating block slowly rotates, it scrapes off the attached material. This linkage realizes three modes: mixing, dispersing, and cleaning, improving the multi-functionality of the equipment.

[0021] 4. This invention achieves stable transmission docking through the cooperation of the positioning ball, positioning cavity and the first compression spring. When the mounting ring is pressed down, the positioning ball inside it is engaged in the positioning cavity at the upper end of the slider under the action of the second compression spring, forming a spherical positioning, which ensures reliable torque transmission between the mounting ring and the first mounting block, so that the transmission is smooth when the movable column drives the rotating block to rotate for cleaning. It is especially suitable for cleaning conditions with low speed and high torque, and extends the service life of the mechanism.

[0022] 5. This invention achieves precise positioning of stirring speed and position through the integration of spline transmission and lifting structure. The servo motor drives the spline teeth to rotate through the adapter teeth. The spline teeth mesh with the second spline groove on the movable column, transmitting torque while allowing the movable column to move freely axially. The telescopic device controls the lifting position of the movable column through the second mounting block, precisely controlling the height of the stirring components at different stages such as wetting, dispersing, and cleaning, improving the accuracy and adaptability of operation, and meeting the production needs of leveling agents.

8. A method for preparing a coating leveling agent using the coating leveling agent production apparatus according to claim 7, characterized in that, Including step 1, feeding and mixing, open the movable cover plate (113), put the solvent of the formula amount into the processing tank (111) through the feed port (112), start the telescopic device (415) to make the movable column (211) in the rising position, and then start the servo motor (416) to drive the movable column (211) and its bottom mounting ring (212), inclined blade turbine propeller (213) and the feeding and stirring structure connected to the inner spline ring (223) through the first spline groove (222) to start rotating. The structure includes a sliding mounting sleeve (214), a propeller (215), a connecting ring (216) and an extrusion groove (217). In the stirring state, the effective component powder of the leveling agent is gradually put into the tank. At this time, the rotating propeller (215) and the connecting ring (216) perform preliminary mixing and shearing of the material, so that the solvent fully wets the surface of the effective component particles and forms a uniform mixture. This low-speed process effectively avoids air entrainment and excessive bubbles. Step 2: High-speed dispersion. After the material is fully soaked, control the telescopic device (415) to drive the movable column (211) to move downward. When the movable column (211) moves downward, the inner spline ring (223) moves to the groove (221) position, causing the material stirring structure to lose its drive and stop under the action of gravity. At the same time, the bowl-shaped dispersion block (322) fixed on the movable column (211) also descends and no longer squeezes the triangular extrusion block (321) fixed on the extension rod (314). Under the pulling force of the third extrusion spring (315), the sliding rod (313) drives the material to move downward. The extension rod (314) retracts inward, so that the extrusion part at its end clamps the outside of the stationary connecting ring (216) and fixes it. Then, the speed of the servo motor (416) is increased, and the movable column (211) drives the inclined blade turbine (213) to rotate through the mounting ring (212), generating radial flow. The fluid moves outward under the action of centrifugal force and is transformed into an axial flow that circulates up and down after hitting the stationary guide plate (218), thereby breaking the vortex and causing the material in the tank to form convection in the longitudinal direction, achieving efficient dispersion, shearing and homogenization, and ensuring that the product reaches the required fineness and uniformity. Step 3: Sampling and testing during or after the dispersion and homogenization process. The material inside the tank needs to be sampled and tested. Lift the installation handle (358) upwards. The sliding column (353) is driven to rise in the second sliding groove (351) through the fixing block (357) and the support rod (356) until the guide hole (354) on it exceeds the position of the permeation groove (352). The liquid inside the tank enters the cavity of the second sliding groove (351) through the permeation groove (352) under static pressure. Then, press the sliding column (353) downwards to make it slide down and close the permeation groove (352). At this time, the liquid in the cavity of the second sliding groove (351) is discharged upwards through the guide hole (354) under pressure and guided to the external container through the connecting rod (355) to obtain a sample for testing. After the sampling is completed, the sliding column (353) is reset. Step 4: Discharge and Equipment Cleaning. After the dispersion and homogenization are completed and the inspection is qualified, open the discharge valve at the bottom of the processing tank (111) to release the leveling agent product, and then clean it: Control the expansion joint (415) to continue to push the movable column (211) downward, so that the first mounting block (335) inside the mounting ring (212) slides downward against the force of the first compression spring (334). When the first mounting block (335) moves down, it pushes the extension rod (314) outward through the rotating rod (342) on its side until its end contacts the inner wall of the processing tank (111). At the same time, the mounting ring (212) The internal positioning ball (3310) is embedded in the positioning cavity (336) on the side of the first mounting block (335) under the action of the second compression spring (339), realizing the transmission connection between the movable column (211) and the rotating block (311). The servo motor (416) is started to rotate, and the movable column (211) drives the rotating block (311) and the extension rod (314) to rotate together through the docking structure. At the same time, the cleaning liquid is sprayed through the feed port (112). The rotating extension rod (314) scrapes off and cleans the residual viscous material attached to the tank wall. The cleaning wastewater is discharged from the bottom, and the cleaning is completed and ready for the next use.
