Description
Technical Field
[0001] This utility model relates to the field of spraying machine technology, specifically a spraying machine for rice cooker inner pots. Background Technology
[0002] A special spraying machine for rice cooker inner pots is a professional device used to spray coatings onto the surface of rice cooker inner pots. It typically uses compressed air to atomize the paint, which is then sprayed out from the nozzle of the spray gun under the action of high-pressure airflow, forming fine paint mist particles.
[0003] When applying a non-stick coating using a specialized spraying machine for rice cooker inner pots, the precise atomization allows for a thinner and more uniform coating, thus ensuring excellent non-stick performance.
[0004] After the rice cooker inner pot is coated with a non-stick coating by a special spraying machine, water-based non-stick paint, which is a type of paint with water as a solvent, will have a certain stickiness when it is not dry. When dust or hair and other impurities approach the undried paint layer, due to the surface tension, the impurities are easily attracted to the paint layer surface and adhere to it. Since the inner pot coating is usually thin, even a small amount of dust particles falling on the inner pot coating being sprayed will form a bump on the coating surface, damaging the smoothness of the coating and affecting the overall quality of the product.
[0005] Therefore, a special spraying machine for rice cooker inner pots is proposed to address the above problems. Utility Model Content
[0006] The purpose of this utility model is to provide a special spraying machine for rice cooker inner pots, in order to solve the problem that because the inner pot coating is usually thin, even a small amount of dust particles falling on the inner pot coating being sprayed will form a bump on the coating surface, damaging the smoothness of the coating and affecting the overall quality of the product.

[0027] Please see Figure 1-5 This utility model provides a technical solution:
[0028] A special spraying machine for rice cooker inner pots includes a spray gun assembly 4 with a paint supply system. A transmission device 1 is provided on one side of the spray gun assembly 4. A fixing device 2 is fixedly connected to the upper end of the transmission device 1. An inner pot 3 is provided on the upper end of the fixing device 2. A purification device 5 is fixedly connected to the outside of the transmission device 1 by bolts. An adjustment device 6 is fixedly connected to one side of the purification device 5.

A fan 53 is fixedly connected to one side of the purification cover 51. A discharge pipe 54 is fixedly connected to the upper end of the purification cover 51. The adjustment device 6 includes a mounting frame 61. A mounting part 62 is installed on one side of the mounting frame 61. A mounting groove 63 is opened on the inner side of the mounting frame 61. A filter plate 64 is installed on the inner side of the mounting groove 63. A limit groove 65 is opened on one side of the filter plate 64. A drive motor 66 is fixedly connected to one side of the mounting frame 61. A rotating shaft 67 is fixedly connected to one end of the main shaft of the drive motor 66. A louvered fan 68 is fixedly connected to the outside of the rotating shaft 67. The rotating shaft 67 is rotatably connected to the inner side of the mounting frame 61.
[0029] As a further implementation of the above technical solution: There are three mounting slots 63 and three filter plates 64. The mounting slots 63 and the filter plates 64 correspond one-to-one. The mounting slots 63 are parallel to each other. The mounting slots 63 are set in a ring shape. The vertical cross section of the mounting slots 63 is square. Through this multi-stage filtration mechanism, impurities in the air can be removed more thoroughly, ensuring that the air entering the spraying area reaches a high level of cleanliness and protecting the inner liner 3 coating from impurities.
[0030] As a further implementation of the above technical solution: a plurality of mounting parts 62 are provided, and the mounting parts 62 are evenly and equidistantly arranged on one side of the mounting frame 61. The mounting parts 62 pass through the mounting frame 61 and the mounting groove 63 and are tightly fitted with the limiting groove 65. The mounting parts 62 and the limiting groove 65 correspond one-to-one. By tightly fitting with the limiting groove 65, the mounting parts 62 ensure that the filter plate 64 is securely installed in the mounting groove 63, which facilitates the installation and replacement of the filter plate 64.
[0031] As a further implementation of the above technical solution: the spray groove 52 is set with a trapezoidal cross-section and is located directly below the nozzle of the spray gun assembly 4. There are two discharge pipes 54, which are L-shaped and parallel to each other. This is conducive to collecting and guiding the paint sprayed by the spray gun assembly 4, avoiding paint splashing everywhere, and improving the utilization rate of paint.
[0032] As a further implementation of the above technical solution: several drive motors 66 and rotating shafts 67 are provided. Both drive motors 66 and rotating shafts 67 are located inside the purification hood 51. There is a one-to-one correspondence between drive motors 66 and rotating shafts 67. One end of the rotating shaft 67 passes through one side of the mounting frame 61. The drive motor 66 drives the rotating shaft 67 to rotate, thereby controlling the angle of the louver 68. The direction and speed of airflow can be flexibly controlled. In the initial stage of spraying, the flow rate can be reduced to prevent the paint from being blown away. In the process of coating drying, the flow rate can be appropriately increased to accelerate drying. At the same time, it ensures that the air is evenly covered on the surface of the inner liner 3, thus optimizing the spraying process and coating quality.
[0033] As a further implementation of the above technical solution: several louvered fans 68 are provided, one side of the louvered fans 68 is set as arc, the louvered fans 68 are closely attached to each other, the louvered fans 68 correspond one-to-one with the rotating shaft 67, and the louvered fans 68 are parallel to each other. By precisely adjusting the angle of the louvered fans 68, the airflow direction and speed can be flexibly controlled.
[0034] As a further implementation of the above technical solution: two adjustment devices 6 are provided. The adjustment devices 6 are located on one side near the spray gun assembly 4. The vertical cross-section of the adjustment devices 6 is rectangular. The adjustment devices 6 are parallel to each other, and the upper ends of the adjustment devices 6 are located on the same horizontal plane. When the spraying begins, the paint has just adhered to the inner liner 3. The louver 68 can be adjusted to a smaller opening degree to keep the airflow speed low and prevent strong airflow from blowing away the paint. When the coating begins to dry, the opening degree of the louver 68 is appropriately increased to increase the airflow speed, accelerate air circulation, remove any water vapor and impurities that may be generated, ensure the coating quality, and improve drying efficiency.
[0035] Workflow: First, the inner liner 3 is placed on the fixing device 2, which securely fixes the inner liner 3 to ensure it will not move during the subsequent spraying process. The transmission device 1 is then activated via an external power line. Its function is to move the inner liner 3 along a predetermined trajectory and speed, allowing the spray gun assembly 4 to spray the inner liner 3 comprehensively and evenly. Supported by the paint supply system, the spray gun assembly 4 begins spraying paint onto the surface of the inner liner 3. The paint sprayed by the spray gun assembly 4 passes through the spray groove 52, providing a comprehensive coating of the inner liner 3. Simultaneously, the purification device 5 starts operating, and the fan 53 is activated, creating a negative pressure environment within the purification hood 51. This causes air to be drawn into the purification hood 51 from the outside. The air mainly enters from one end of the mounting frame 61. Filter plates 64 are installed in the mounting slots 63. Multiple filter plates 64 in the mounting slots 63 can filter different... Impurities of the same particle size are filtered. The mounting part 62 fits tightly with the limiting groove 65 of the filter plate 64 through the mounting frame 61 and the mounting groove 63, ensuring that the filter plate 64 is securely installed in the mounting groove 63. The drive motor 66 starts and drives the rotating shaft 67 to rotate. By adjusting the angle of the louvered fan 68, the airflow direction and speed can be precisely controlled to ensure that the air can be evenly covered on the surface of the inner liner 3, while avoiding strong airflow from interfering with the spraying process. The filtered clean air is discharged through the exhaust pipe 54 under the action of the fan 53, which can blow clean air evenly to the surface of the inner liner 3. This circulation method can form a stable clean airflow area around the sprayed inner liner 3, driving away any dust, hair and other impurities that may be present from the spraying area. At the same time, the flowing air can remove moisture from the surface of the paint layer, which helps the water-based non-stick coating to dry quickly.
[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
