Description

Technical Field

[0001] The utility model belongs to the technical field of powder coating preparation, and particularly relates to a cooling device for powder coating preparation. Background Art

[0002] Powder coatings are solid powder synthetic resin coatings composed of solid resins, pigments, fillers, and additives. There are two main categories of powder coatings: thermoplastic and thermosetting. The film appearance of thermoplastic powder coatings is poor, and the adhesion to metals is also poor. Therefore, they are rarely used in the field of automotive painting. Automotive painting generally uses thermosetting powder coatings. Thermosetting powder coatings use thermosetting synthetic resins as film-forming substances. During the drying process, the resin first melts and then cures into a smooth and hard film through chemical cross-linking.

[0003] During the processing of thermosetting powder, it needs to be cooled. Currently, the existing cooling method often places the thermosetting powder in a designated position and uses the static method to allow the thermosetting powder coating to cool naturally. However, this cooling method has low efficiency. Not only will dust particles and the like enter and fall into the thermosetting powder during the static process, but it will also affect the production efficiency of the subsequent thermosetting powder coating, reducing the practicality of the device. Summary of the Utility Model

[0023] An electric push rod 3 is arranged inside the main body bin 1 and outside the preparation bin 2. A support plate 4 is fixed to the output end of the electric push rod 3. A preparation and mixing mechanism is arranged inside the support plate 4. The preparation and mixing mechanism includes a servo motor 5, a connecting rod 6, and a stirring paddle 7. The servo motor 5 is fixed at the central position of the upper end face of the support plate 4. The connecting rod 6 is fixed to the output end of the servo motor 5. The stirring paddle 7 is fixed to the outer surface of the connecting rod 6. By setting the electric push rod 3, the position of the support plate 4 can be adjusted, so that the preparation bin 2 can be opened, facilitating subsequent replenishment of thermosetting powder. The set servo motor 5 can drive the connecting rod 6 to rotate. When the connecting rod 6 rotates, the powder coating can be stirred by the stirring paddle 7, avoiding caking of the powder coating and affecting subsequent cooling treatment. A cleaning plate 8 is fixed to one side of the connecting rod 6, and the cross-section of the cleaning plate 8 is a "U" - shaped structure. The outer surface of the cleaning plate 8 is in close contact with the inner wall of the preparation bin 2. By setting the cleaning plate 8, it can be in close contact with the inner wall of the preparation bin 2 to clean the inner wall of the preparation bin 2, preventing the powder coating from adhering to the inner wall of the preparation bin 2 and affecting subsequent processing;

[0024] A water bin 9 is arranged on one side of the main body bin 1. A refrigeration mechanism is arranged inside the water bin 9. The refrigeration mechanism includes a semiconductor refrigeration plate 10, a connection pump 11, a spiral tube 12, and a return pipe 13.

The return pipe 13 is connected to the tail end of the spiral tube 12, and the other end of the return pipe 13 is connected to the water bin 9. By setting the semiconductor refrigeration plate 10, the water in the water bin 9 can be cooled. Then, through the connection pump 11, the cooled water is guided into the spiral tube 12, reducing the temperature of the preparation bin 2, quickly cooling the thermosetting powder in the preparation bin 2, ensuring subsequent processing, and at the same time preventing dust and the like from entering the thermosetting powder. Then, the set return pipe 13 can re - flow back to the inside of the water bin 9, enabling the water to circulate and avoiding waste of resources. A discharge port 14 is opened on the lower end face of the main body bin 1. By setting the discharge port 14, it is convenient to discharge the cooled thermosetting powder for subsequent processing;

[0025] First, the position of the support plate 4 is adjusted by the electric push rod 3, and then the thermosetting powder can be placed in the preparation bin 2. After that, the support plate 4 and the main body bin 1 are closed. Then, the semiconductor refrigeration plate 10 can cool the water in the water bin 9, and the cooled water is guided into the spiral tube 12 through the connecting pump 11, so as to reduce the temperature of the preparation bin 2. Subsequently, the set return pipe 13 can reflow to the inside of the water bin 9, so that the water can circulate. At the same time, the set servo motor 5 can drive the connecting rod 6 to rotate. When the connecting rod 6 rotates, the powder coating can be stirred by the stirring paddle 7, so as to avoid caking of the powder coating and the like.
