Description

Technical Field

[0001] This utility model relates to the field of water-based coating processing, and in particular to a stirring device for water-based coating processing. Background Technology

[0002] In the fields of interior decoration and industrial coating, water-based coatings are widely used due to their excellent properties such as environmental friendliness, non-toxicity, and easy drying. To ensure stable performance and uniform color, the coating must be thoroughly stirred before use to mix the precipitated pigments and additives evenly. This process usually relies on a dedicated stirring device, in which a motor drives a stirring rod to rotate at high speed within the container, thereby completing the mixing of the coating.

[0003] However, traditional mixing devices inevitably incorporate a large amount of air during vigorous mixing, resulting in numerous and fine air bubbles inside the coating. These bubbles float on the surface of the coating, and if they are not eliminated in time, they will directly affect the film quality and cause surface defects. Currently, the commonly used defoaming method in the industry is to let the coating stand for a long time after stopping mixing, relying on the bubbles to burst naturally. This method is extremely inefficient and seriously slows down the production pace and construction progress. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing water-based coating mixing devices, which cannot quickly remove air bubbles, and to propose a mixing device for water-based coating processing.

[0005] To address the problems existing in the prior art, the present invention adopts the following technical solution: A mixing device for processing water-based coatings includes a frame, a top plate movably mounted on the top of the frame, a mixing motor mounted on the upper surface of the top plate, and a mixing tank disposed on the frame. A mixing rod for mixing the coating is rotatably provided at the end of the top plate. The output end of the mixing motor is connected to the upper end of the mixing rod. A lifting assembly is provided on the mixing rod, and a spiked plate is sleeved on the mixing rod. The lifting assembly is rigidly connected to the spiked plate. The lifting assembly is configured to drive the spiked plate to move up and down reciprocally through the rotation of the mixing rod to puncture air bubbles floating on the surface of the water-based coating.

[0006] Preferably, the lifting assembly includes an adjusting component and a driving component. The adjusting component includes a fixed rod that is vertically installed on the lower surface of the top plate. A movable rod is slidably provided inside the fixed rod. A bolt is threaded on the outer wall of the fixed rod. The lower end of the movable rod is fixedly connected to the driving component.

[0007] Preferably, the driving component includes a housing fixedly installed at the lower end of the moving rod, a bearing fixedly connected to the upper end of the inner cavity of the housing, an inner shell fixedly connected to the inner ring of the bearing, the inner shell sleeved on the outer wall of the stirring rod, a driving ring fixedly provided on the outer wall of the inner shell, a driving block slidably provided in the groove of the edge of the housing, one end of the driving block being in contact with the inclined surface of the driving ring, a connecting rod fixedly provided at the other end of the driving block, the lower end of the connecting rod being fixedly connected to the upper surface of the spike plate, and a limiting component provided between the groove of the edge of the housing and the driving block.

[0008] Preferably, a rectangular rod is vertically arranged on the outer wall of the stirring rod, and the rectangular rod is connected to a groove key on the inner side of the inner shell.

[0009] Preferably, the limiting member includes two limiting rods fixedly installed in the edge groove of the housing. The two limiting rods pass through the driving block. A spring is sleeved on the limiting rod. The lower end of the spring is connected to the upper surface of the driving block, and the upper end of the spring is connected to the top of the edge groove of the driving block.

[0010] Preferably, a base plate is rotatably mounted on the frame, the mixing tank is fitted into a groove in the base plate, a gear ring is fixedly mounted on the outer wall of the base plate, a drive motor is fixedly mounted on the frame, and a gear is fixedly mounted on the output end of the drive motor, the gear meshing with the gear ring.

[0011] Compared with the prior art, the beneficial effects of this utility model are: In this invention, the lifting assembly is driven by the rotation of the stirring rod, which in turn moves the spiked plate up and down reciprocally on the coating surface, directly puncturing the air bubbles generated during the stirring process. Compared to the traditional static defoaming method, this eliminates the need for long waiting times and can remove air bubbles instantly, significantly improving production efficiency. Simultaneously, the continuous movement of the spiked plate ensures that air bubbles are removed promptly, preventing quality defects such as pinholes and blistering in the coating after application, effectively improving coating quality.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or implementations.

[0017] Example: This example provides a stirring device for processing water-based coatings. See [link to example]. Figure 1-5 Specifically, it includes a frame 1, a top plate 12 movably mounted on the top of the frame 1, a stirring motor 13 mounted on the upper surface of the top plate 12, and a stirring tank 11 mounted on the frame 1. The top plate 12 is rotatably equipped with a stirring rod 14 for stirring the coating. The output end of the stirring motor 13 is connected to the upper end of the stirring rod 14. The stirring rod 14 is equipped with a lifting assembly 2, and a spike plate 15 is sleeved on the stirring rod 14. The lifting assembly 2 is rigidly connected to the spike plate 15. The lifting assembly 2 is configured to drive the spike plate 15 to move up and down reciprocally through the rotation of the stirring rod 14 to puncture the air bubbles floating on the surface of the water-based coating.

[0018] In this embodiment, the frame 1 serves as the basic support structure, supporting components such as the top plate 12 and the mixing tank 11, ensuring the overall stability of the device. The top plate 12 is movably installed on the top of the frame 1. Two round rods are provided at the upper end of the frame 1. After the top plate 12 is fitted onto the two round rods, it is fixed with nuts. By disassembling the top plate 12, the mixing rod 14 is moved out of the mixing tank 11. The mixing rod 14 passes through the top plate 12 and extends into the mixing tank 11. The upper end is connected to the motor output end, and the lower end is equipped with mixing blades. The rotation achieves uniform mixing of the coating. The spiked plate 15 is fitted on the outside of the mixing rod 14, without contacting the outer wall of the mixing rod 14. The lower surface is covered with needle-like protrusions or sharp edges, which directly puncture air bubbles on the coating surface through reciprocating motion, avoiding coating defects.

[0019] In the specific implementation process, such as Figure 2 and Figure 3 As shown, the lifting assembly 2 includes an adjusting component and a driving component 3. The adjusting component includes a fixed rod 21 that is vertically installed on the lower surface of the top plate 12. A movable rod 22 is slidably provided inside the fixed rod 21. A bolt 23 is threaded on the outer wall of the fixed rod 21. The lower end of the movable rod 22 is fixedly connected to the driving component 3.

[0020] In this embodiment, the fixed rod 21 is vertically fixed to the lower surface of the top plate 12 and serves as the sliding guide for the moving rod 22. The moving rod 22 can slide up and down within the fixed rod 21, and the entire drive component 3 is mounted at its lower end. After the bolt 23 is tightened, it can directly press against the moving rod 22, fixing it at the required height. This adjusting component is used to adjust the initial height of the entire drive component 3 and the barbed plate 15 to adapt to different liquid levels, ensuring that the barbed plate 15 can work in the optimal position.

[0021] In the specific implementation process, such as Figure 3 and Figure 4 As shown, the driving component 3 includes a housing 31 fixedly installed at the lower end of the moving rod 22. A bearing 32 is fixedly connected to the upper end of the inner cavity of the housing 31. An inner shell 33 is fixedly connected to the inner ring of the bearing 32. The inner shell 33 is sleeved on the outer wall of the stirring rod 14. A driving ring 34 is fixedly provided on the outer wall of the inner shell 33. A driving block 35 is slidably provided in the groove at the edge of the housing 31. One end of the driving block 35 is in contact with the inclined surface of the driving ring 34. A connecting rod 36 is fixedly provided at the other end of the driving block 35. The lower end of the connecting rod 36 is fixedly connected to the upper surface of the spike plate 15. A limiting component is provided between the groove at the edge of the housing 31 and the driving block 35.

[0022] In this embodiment, the bearing 32 connects the outer shell 31 and the inner shell 33, allowing the inner shell 33 to rotate within the outer shell 31 while bearing axial force. The core transmission component of the inner shell 33 is driven to rotate by the stirring rod 14 via the rectangular rod 4. Its outer wall is provided with a drive ring 34. The drive ring 34 is a key component, and its surface is designed with inclined tracks. The drive block 35 is installed in the edge groove of the outer shell 31, with one end pressed by a spring 51, ensuring the other end is always in contact with the complex surface of the drive ring 34. The connecting rod 36 connects the drive block 35 and the spike plate 15, transmitting the movement of the drive block 35. The rotation of the stirring rod 14 causes the inner shell 33 to rotate. When the inner shell 33 rotates with the drive ring 34, the inclined surface of the drive ring 34 periodically pushes against the drive block 35. Since the movement of the drive block 35 is restricted to the horizontal direction by the limiting rod 5, it pulls the spike plate 15 downwards via the connecting rod 36.

[0023] In the specific implementation process, such as Figure 3 and Figure 4 As shown, a rectangular rod 4 is vertically mounted on the outer wall of the stirring rod 14, and the rectangular rod 4 is keyed to a groove on the inner side of the inner shell 33. The rectangular rod 4 is fixed to the outer wall of the stirring rod 14, and its key function is to cooperate with the groove on the inner side of the inner shell 33 to form a spline structure. This allows the inner shell 33 to slide up and down along the stirring rod 14, and at the same time be driven to rotate with the stirring rod 14.

[0024] In the specific implementation process, such as Figure 3 and Figure 5 As shown, the limiting component includes two limiting rods 5 fixedly installed in the edge groove of the housing 31. The two limiting rods 5 pass through the drive block 35, and springs 51 are sleeved on the limiting rods 5. The lower end of the springs 51 is connected to the upper surface of the drive block 35, and the upper end of the springs 51 is connected to the top of the edge groove of the drive block 35. The limiting rods 5 are fixed to the housing 31 and pass through the drive block 35, ensuring that the drive block 35 can only move linearly in the horizontal direction and cannot tilt or rotate. The springs 51 provide a clamping force to reset the drive block 35 and keep it in close contact with the drive ring 34, which is the key to realizing the reciprocating motion.

[0025] In the specific implementation process, such as Figure 1 and Figure 2 As shown, a base plate 6 is rotatably mounted on the frame 1, and a mixing tank 11 is fitted into a groove in the base plate 6. A toothed ring 61 is fixedly mounted on the outer wall of the base plate 6. A drive motor 62 is fixedly mounted on the frame 1, and a gear 63 is fixedly mounted on the output end of the drive motor 62. The gear 63 meshes with the toothed ring 61.

[0026] In this embodiment, the mixing tank 11 is located in the base plate 6, and the stirring rod 14 inside the tank is located at the edge. The drive motor 62 works, and through the meshing of the gear 63 and the gear ring 61, it drives the base plate 6 and the mixing tank 11 on it to rotate slowly. This design allows the stirring rod 14 and the spike plate 15 to contact more areas of the coating inside the tank, avoiding dead zones in mixing and defoaming, resulting in more uniform mixing and more thorough defoaming.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
