A coating is a material that can be applied to the surface of an object using different construction processes to form a solid film that adheres firmly, has a certain strength, and is continuous. The film formed in this way is generally called a coating film, also known as a paint film or a coating layer. A coating generally consists of four parts: a film-forming substance, fillers (pigment fillers), solvents, and additives. Sometimes the composition may vary slightly according to performance requirements. For example, varnish does not have pigment fillers, and powder coatings may not have solvents. It belongs to organic chemical engineering polymer materials, and the formed coating film belongs to the type of polymer compounds. According to the modern classification of chemical industrial products, coatings belong to fine chemical products. Modern coatings are gradually becoming a type of multifunctional engineering material and are an important industry in the chemical industry.

[0023] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims. Example

[0024] refer to Figures 1-3 This embodiment proposes a continuous paint processing device for easy viscosity detection, used to mix paint and ensure its uniform quality to achieve a specified consistency. The continuous paint processing device for easy viscosity detection includes:

[0025] The mixing tank 3 can be a horizontally arranged cylindrical structure, forming a mixing space for the paint. The cylindrical interior minimizes dead zones and prevents paint residue. The mixing tank 3 generally requires a certain degree of sealing and rigidity to prevent deformation and leakage during operation. The mixing tank 3 may include a cylindrical body 7 and end caps 8. The cylindrical body 7 has a cylindrical structure, and the end caps 8 are located at both ends of the cylindrical body 7. The end caps 8 and the cylindrical body 7 are circumferentially fixed together with screws, allowing for a detachable connection and facilitating cleaning and maintenance of the mixing tank 3. The two ends of the mixing tank 3 can be connected to an inlet pipe 4 and a outlet pipe 2. Paint raw materials can be added into the mixing tank 3 through the inlet pipe 4, and the processed paint liquid can be discharged through the outlet pipe 2. Various paint raw materials can be added to the mixing tank 3 through the feed pipe 4 according to the mixing ratio. Since the device is a continuous processing system, the feed gradient of the raw materials may deviate, resulting in differences in the fed paint raw materials. This leads to uneven quality in the packaged products, requiring continuous consistency testing. A control valve can be installed on the feed pipe 4; opening the valve allows the paint raw materials to be added to the mixing tank 3 through the feed pipe 4. The feed pipe 4 and the discharge pipe 2 can be connected at both ends of the mixing tank 3, allowing the paint liquid to churn and flow axially within the mixing tank 3. The feed pipe 4 can be connected to the upper part of the mixing tank 3, allowing gravity to fully penetrate the mixing tank 3. The discharge pipe 2 can be located at the bottom of the mixing tank 3, facilitating the complete discharge of all paint raw materials inside the mixing tank 3, preventing liquid residue. A vent hole can be connected to the top of the mixing tank 3 to facilitate the discharge of air from inside the mixing tank 3. The vent hole can correspond to the position of the discharge pipe 2. Of course, it is not impossible for the discharge pipe 2 to be connected to the top of the mixing tank 3, which facilitates the full-tank processing of the mixing tank 3. The vent hole only allows gas to be discharged. The specific details are existing technology and will not be elaborated here. The bottom of the mixing tank 3 can be equipped with a base 1 by a bracket. The base 1 can be a frame structure or a rectangular plate structure. It has a certain weight and the setting of the base 1 can make the mixing tank 3 stable and prevent shaking during the operation of the device.

[0026] A rotating shaft 9 is rotatably positioned at the center of the mixing tank 3. A stirring blade 10 is fixedly mounted on the rotating shaft 9. The stirring blade 10 can rotate with the rotating shaft 9, thereby stirring inside the mixing tank 3, causing the paint liquid inside the mixing tank 3 to churn and complete the mixing of various paint raw materials.

[0027] A rotation drive component 5, connected to the rotation shaft 9, drives the rotation shaft 9 to rotate at a constant speed. The rotation shaft 9 can rotate in both forward and reverse directions. The rotation drive component 5 may include a motor and a belt transmission structure. The motor may be a three-phase motor, which can be mounted on the base 1. The output shaft of the motor is coaxially fixedly connected to a pulley. One end of the rotation shaft 9 extends out of the mixing tank 3 and is coaxially fixedly connected to a pulley. The two pulleys are connected by a belt. Driven by the motor, the rotation shaft 9 can rotate at a constant speed. The stirring blade 10 may be a spiral long strip plate structure. When the rotation shaft 9 rotates in the forward direction, it can cause the paint liquid to tumble inside the mixing tank 3, and simultaneously convey and mix the paint raw materials entering from the feed pipe 4. At this time, one-way valves may be installed inside the discharge pipe 2 and the feed pipe 4 to restrict the flow direction of the paint liquid and prevent the paint liquid from flowing out through the feed pipe 4. The rotating shaft 9 rotates in the opposite direction. Since the discharge pipe 2 and the feed pipe 4 are equipped with one-way valves, which restrict the reverse flow of the paint liquid, the stirring blade 10 rotates in the opposite direction with the rotating shaft 9. This allows the paint liquid inside to not only circumferentially tumble, but also axially and internally, ensuring the uniformity of the paint liquid mixing. The cross-section of the stirring blade 10 can form an obtuse angle with the tangent of the mixing tank 3 in the direction of rotation, preferably between 100° and 150°. Other values ​​are not excluded, but will not be elaborated here. This allows the stirring blade 10 to push the paint liquid to circumferentially and axially tumble, while also circulating it internally and externally, thereby increasing the uniformity of the paint liquid mixing. The outer arm of the stirring blade 10 can contact the inner wall of the mixing tank 3, facilitating the removal of paint material adhering to the inner wall of the mixing tank 3. The helical angle of the stirring blade 10 can be 5-20° / m, that is, the pitch is between 18-72m, ensuring sufficient mixing time for the paint liquid. Further details will not be elaborated here. The width of the stirring blade 10 can be 0.1-0.5 times the radius of the stirring tank 3, preferably 1 / 3 of the radius of the stirring tank 3, to ensure the rate of internal and external circulation.

[0028] A torque sensor 11 is installed on the rotating shaft 9. The torque sensor 11 is used to detect the torsional resistance experienced by the rotating shaft 9 during rotation. The position of the torque sensor 11 corresponds to the position of the discharge pipe 2. The structure of the torque sensor 11 is existing technology and will not be described in detail here.

[0029] The controller 6 can be electrically connected to the rotary drive 5 and the torque sensor 11. The controller 6 can control the rotation direction and speed of the rotary drive 5. Under normal circumstances, the stirring speed remains constant during processing, although increasing the speed to improve production efficiency is possible. The specific structure of the controller 6 is existing technology and will not be described in detail here. The controller 6 can also be used to receive the torque detected by the torque sensor 11. In this embodiment, it is assumed that the paint raw materials entering the mixing tank 3 from the feed pipe 4 have been strictly prepared according to the ratio, but there is a possibility of uneven mixing. Paint raw materials are added to the mixing tank 3 according to the mixing ratio through the feed pipe 4. The controller 6 controls the rotating drive 5 to drive the rotating shaft 9 to rotate in the forward direction. The paint raw materials enter the mixing tank 3, and the stirring blades 10, along with the rotating shaft 9, stir and mix the paint liquid inside the mixing tank 3 and convey it along the axial direction of the mixing tank 3. When the mixed paint liquid reaches the lateral position of the discharge pipe 2, it is detected by the torque sensor 11 to obtain the torsional resistance F. The controller determines whether the torsional resistance F is within a preset standard torsional resistance range (F0-f, F0+f). If it is, the controller 6 controls the rotating shaft 9 to rotate in the forward direction. If not, it indicates that there is uneven mixing, so the controller 6 controls the rotating shaft 9 to rotate in the reverse direction. Then, after a preset time interval, the controller continues to judge and execute the above steps. F0 is the torsional resistance obtained by detecting the standard paint liquid in the mixing tank 3 at the same stirring speed, which will not be elaborated here. f is the deviation torque, which generally needs to be set according to the company's quality standards. The specific value is generally between 10-100N, which will not be elaborated here. The preset time period can be set based on experience, generally between 10 and 60 seconds, although other values ​​are not excluded. This method allows for continuous paint processing with high efficiency, enabling continuous production. It is simple to operate and easy to control. Furthermore, viscosity detection does not require sampling, enabling real-time monitoring. The system can automatically adjust stirring based on the detection data, resulting in high mixing efficiency, high production quality, and ease of widespread adoption.

[0030] It should be understood that the various forms of processes shown above can be used to rearrange, add, or delete steps. For example, the steps described in this disclosure can be executed in parallel, sequentially, or in different orders, as long as the desired result of the technical solution disclosed in this disclosure can be achieved, and this is not limited herein.

[0031] The specific embodiments described above do not constitute a limitation on the scope of protection of this disclosure. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
