[0002] A casting is a metal shaped object obtained by various casting methods, that is, the smelted liquid metal is poured into a pre-prepared mold by pouring, injection, suction or other casting methods, and then cooled and polished to obtain an object with a certain shape, size and performance. During the casting process, the casting needs to be sprayed, and the paint used for spraying needs to be stirred before use, otherwise it will affect the quality of the casting spray.

In addition, the traditional paint stirring equipment mostly eliminates the particles generated in the paint by increasing the stirring time, causing the particles to rotate and rub for a long time inside the paint and eventually break up and merge into the paint. If the stirring time is too long, the surface tension and viscosity of the paint will change, resulting in problems such as uneven coating, whitening, and bubbling during painting. Therefore, it cannot meet the existing use requirements of paint stirring equipment. Summary of the invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a paint stirring device for casting spraying and its use method, which can monitor the rotation speed of the stirring shaft to reflect the fineness and viscosity of the paint inside the stirring drum in real time, and can eliminate the internal agglomerates of the paint without increasing the stirring time.

The driving speed sensor is arranged on the bottom wall of the driving disk, and the stirring speed sensor is arranged on the upper wall of the stirring disk.

[0007] When in use, the components of the prepared paint are put into the mixing drum, and the driving electromagnet and the stirring electromagnet are energized to generate magnetism respectively. The driving electromagnet and the stirring electromagnet are set with opposite poles, and the driving electromagnet and the stirring electromagnet attract each other. At this time, the driving electromagnet and the stirring electromagnet are set vertically, and the driving motor drives the driving disk to rotate through the power end, and the driving disk drives the driving electromagnet to rotate. The driving electromagnet drives the stirring electromagnet to rotate through the magnetic force, and the stirring electromagnet drives the stirring disk to rotate through the stirring disk, and the stirring disk drives the stirring blades to stir the paint components inside the mixing drum. In the early stage of stirring, the agglomeration between the macromolecular chains or particles in the paint is gradually broken. As the stirring proceeds, the paint becomes more The coating will be more uniform and delicate with increasing stirring time, and the viscosity of the coating will gradually decrease, thereby reducing the resistance to the stirring blades. Therefore, when the driving electromagnet drives the stirring electromagnet to rotate, the stirring blades are subject to certain resistance during rotation.

[0009] During use, the paint components inside the mixing drum produce centrifugal motion under the stirring of the stirring blades, and the agglomerates and impurities in the paint components gradually separate and come into contact with the deagglomeration plate. Since the gap between the deagglomeration plate and the deagglomeration plate is small, the deagglomeration plate drives the agglomerates to move along the deagglomeration plate during the rotation of the stirring blades. When more agglomerates gather near the deagglomeration plate, the agglomerates will enter the gap between the deagglomeration plate and the ball-circling plate. The agglomerates are easy to loosen when encountering external force. The agglomerates are turned into powder under the extrusion force of the deagglomeration plate and the ball-circling plate and integrated into the paint to ensure uniform mixing of the paint components.

[0010] Specifically, a controller is provided on the upper wall of the material discharge seat.

[0011] Wherein, the controller is electrically connected to the driving motor, the driving electromagnet, the stirring electromagnet, the driving speed sensor, the stirring speed sensor and the discharging electromagnet respectively.

[0012] Preferably, the models of the driving speed sensor and the stirring speed sensor are.

[0013] A method for using a paint stirring device for casting spraying is as follows: Step 1: Put the components of the prepared coating into the mixing drum, and energize the driving electromagnet and the stirring electromagnet to generate magnetism, and the driving electromagnet and the stirring electromagnet are vertically arranged; Step 2: The driving motor drives the driving disk to rotate through the power end, the driving disk drives the driving electromagnet to rotate, the driving electromagnet drives the stirring electromagnet to rotate through the magnetic force, the stirring electromagnet drives the stirring disk to rotate through the stirring disk, and the stirring disk drives the stirring blades to stir the coating components inside the stirring drum; Step 3: The coating components inside the mixing drum generate centrifugal motion under the stirring of the stirring blades, and the agglomerates and impurities in the coating components gradually separate, and the agglomerates and impurities come into contact with the deagglomeration plate; Step 4: The deagglomeration plate drives the particles to move along the deagglomeration plate as it rotates with the stirring blade. When there are more particles gathered near the deagglomeration plate, the particles will enter the gap between the deagglomeration plate and the ball-circling plate. Under the extrusion force of the deagglomeration plate and the ball-circling plate, the particles will turn into powder and be integrated into the coating.

[0014] The beneficial effects achieved by adopting the above structure are as follows: Compared with the prior art, the present invention adopts a method of combining air-space magnetic drive with a centrifugal agglomeration mechanism, and sets a return speed type mixing mechanism and a grinding ball type discharging mechanism.

Moreover, by utilizing the extrusion of the deagglomeration plate and the ball-circling plate, the coating components can be evenly fused under the condition of avoiding long-term stirring of the coating components. , which can not only ensure the mixing quality of the paint, but also reduce the mixing time of the paint, and improve the stirring efficiency of the paint components to a certain extent. As the stirring time increases, the viscosity of the paint will gradually decrease, thereby reducing the resistance to the stirring blades. Therefore, when the driving electromagnet drives the stirring electromagnet to rotate, the stirring blades are subject to a certain resistance during the rotation process. The driving speed sensor and the stirring speed sensor monitor the rotation speed of the driving disk and the stirring disk respectively. The driving speed sensor and the stirring speed sensor detect that the rotation speeds of the driving disk and the stirring disk are inconsistent, indicating that the mixing operation of the paint components needs to continue.

[0024] The controller 34 is electrically connected to the driving motor 8 , the driving electromagnet 10 , the stirring electromagnet 14 , the driving speed sensor 17 , the stirring speed sensor 18 and the discharging electromagnet 29 , respectively.

[0025] The models of the driving speed sensor 17 and the stirring speed sensor 18 are.

[0026] A method for using a paint stirring device for casting spraying is as follows: Step 1: Put the components of the prepared coating into the mixing drum 3, and energize the driving electromagnet 10 and the stirring electromagnet 14 to generate magnetism, and the driving electromagnet 10 and the stirring electromagnet 14 are arranged vertically; Step 2: The driving motor 8 drives the driving disk 9 to rotate through the power end, the driving disk 9 drives the driving electromagnet 10 to rotate, the driving electromagnet 10 drives the stirring electromagnet 14 to rotate through the magnetic force, the stirring electromagnet 14 drives the stirring disk 13 to rotate through the stirring disk 13, and the stirring disk 13 drives the stirring blade 15 to stir the coating components inside the stirring drum 3; Step 3: The coating components inside the mixing drum 3 generate centrifugal motion under the stirring of the stirring blade 15, and the agglomerates and impurities in the coating components gradually separate, and the agglomerates and impurities contact the agglomeration elimination plate 21; Step 4: The deagglomeration plate 21 drives the particles to move along the deagglomeration plate 21 as it rotates following the stirring blade 15. When a large number of particles gather near the deagglomeration plate 22, the particles will enter the gap between the deagglomeration plate 21 and the ball-circling plate 22. Under the extrusion pressure of the deagglomeration plate 21 and the ball-circling plate 22, the particles will become powder and be integrated into the coating.

[0027] When in use, in the initial state, the limit block 28 is located inside the limit groove 27, the side wall of the closing plate 26 fits with the inner wall of the discharge port 33, the discharge port 33 is blocked and cut off, and the components for preparing the coating are placed inside the mixing drum 3; The controller 34 controls the driving electromagnet 10 and the stirring electromagnet 14 to start, and the driving electromagnet 10 and the stirring electromagnet 14 are energized to generate magnetism respectively. The driving electromagnet 10 and the stirring electromagnet 14 are arranged with different poles, and the driving electromagnet 10 and the stirring electromagnet 14 attract each other. At this time, the driving electromagnet 10 and the stirring electromagnet 14 are arranged vertically, and the driving motor 8 drives the driving disk 9 to rotate through the power end, and the driving disk 9 drives the driving electromagnet 10 to rotate. The driving electromagnet 10 drives the stirring electromagnet 14 to rotate through the magnetic force, and the stirring electromagnet 14 drives the stirring disk 13 to rotate through the stirring disk 13, and the stirring disk 13 drives the stirring blade 15 to stir the coating components inside the stirring drum 3; The coating components in the mixing drum 3 generate centrifugal motion under the stirring of the stirring blades 15, and the agglomerates and impurities in the coating components gradually separate, and the agglomerates and impurities contact the agglomeration elimination plate 21; In the initial stage of stirring the coating components, the agglomeration between the macromolecular chains or particles in the coating is gradually broken. As the stirring proceeds, the coating becomes uniform and fine. As the stirring time increases, the viscosity of the coating will gradually decrease, thereby reducing the resistance to the stirring blade 15. Therefore, in the initial stage of stirring, when the driving electromagnet 10 drives the stirring electromagnet 14 to rotate, since the stirring blade 15 is subject to a certain resistance during the rotation, the controller 34 controls the driving speed sensor 17 and the stirring speed sensor 18 to start.

The driving speed sensor 17 and the stirring speed sensor 18 detect that the rotation speeds of the driving disk 9 and the stirring disk 13 are inconsistent, and the coating components are not mixed evenly enough. The stirring operation of the coating components needs to be continued; Since the gap between the ball-circling plate 22 and the agglomeration plate 21 is small, the agglomeration plate 21 drives the agglomerates to move along the agglomeration plate 21 during the rotation of the stirring blade 15. When the ball-circling plate 22 is close to the agglomeration plate 21 and there are many agglomerates gathered, the agglomerates will enter the gap between the agglomeration plate 21 and the ball-circling plate 22. The agglomerates are easy to loosen when encountering external force. The agglomerates are turned into powder under the extrusion force of the agglomeration plate 21 and the ball-circling plate 22, and are integrated into the coating to ensure uniform mixing of the coating components. When the driving speed sensor 17 and the stirring speed sensor 18 detect that the rotation speeds of the driving disc 9 and the stirring disc 13 are consistent, the resistance of the stirring blade 15 in the fused paint is reduced, and the fineness and viscosity of the paint meet the needs of the user, thereby completing the stirring operation of the paint components; The paint bucket is placed below the discharge port 35, and the controller 34 controls the discharge electromagnet 29 to start. The discharge electromagnet 29 is energized to generate magnetism, and the discharge electromagnet 29 adsorbs the fixed iron block 25. The discharge electromagnet 29 drives the closing plate 26 to slide and rise along the guide sleeve 24, and the closing plate 26 is away from the inside of the discharge port 33. The discharge port 33 is turned on, and the paint stirred in the mixing drum 3 is filtered by the filter plate 31 and falls into the paint bucket, completing the mixing operation of the paint. Repeat the above operation when using it next time.

[0028] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0029] The above is a description of the present solution and its implementation methods, which is not restrictive. The drawings show only one implementation method of the present solution, and the actual structure is not limited thereto.
