[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) This device can improve the stability of the internal temperature of the baking chamber, thereby improving the efficiency of drying the workpiece inside the baking chamber.

[0014] (2) This device sets a second exhaust pipe at the top of the baking chamber and connects the second exhaust pipe to the filter box so that the gas discharged from the baking chamber enters the filter box for filtration and then is discharged.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4This utility model provides a technical solution: a rapid baking device for water-based acrylic amino paint, including a shell 2. Inside the shell 2 are a preheating chamber 4, a baking chamber 17, and a cooling chamber 13. Openings are provided on both sides of the baking chamber 17, and partitions 6 are inserted inside the openings. An electric cylinder 7 is connected to the top of the partition 6 and is fixed to the top side of the shell 2 by a bracket. This structure allows the electric cylinder 7 to automatically raise and lower the partition 6. The partition 6 ensures the movement of the chain conveyor mechanism 18 while maintaining the temperature inside the baking chamber 17 as much as possible. The preheating chamber 4 houses the chain conveyor mechanism 18, one side of which penetrates the baking chamber 17 and is located in the cooling chamber 13. One end of the chain conveyor mechanism 18 is connected to a drive motor 22. The baking chamber 17 is equipped with a first heating tube 16. The drive motor 22 housing is bolted to the outer wall of the outer casing 2. A chain conveyor mechanism 18 transports the workpiece from the preheating chamber 4 to the cooling chamber 13. A gap is maintained between the chain conveyor mechanism 18 and the partition plate 6; this gap should be as small as possible while ensuring the chain conveyor mechanism 18 can move. Both the preheating chamber 4 and the cooling chamber 13 have openings on one side, with doors 14 hinged to the inside of each opening. The doors 14 ensure the sealing of the preheating chamber 4 and the cooling chamber 13. A cooling fan 12 is installed at the top of the cooling chamber 13, and a first exhaust pipe 15 is connected to one side of the cooling chamber 13. A solenoid valve 10 is also installed on the first exhaust pipe 15. This structure allows the cooling fan 12 to control the cooling... The workpiece inside chamber 13 is cooled to accelerate the baking process. A second exhaust pipe 11 is connected to the top of the baking chamber 17. A solenoid valve 10 is installed on the second exhaust pipe 11. One end of the second exhaust pipe 11 is connected to a filter box 5. An opening is opened on one side of the filter box 5, and a drawer box 9 is inserted into the opening. The drawer box 9 contains filter cotton 19, an adsorption plate 20, and a filter screen 21. This structure allows for easy replacement or maintenance of the filter cotton 19, adsorption plate 20, and filter screen 21 by pulling out the drawer box 9. The gap between the drawer box 9 and the filter box 5 is sealed with a sealing ring. An adsorption plate 20 is installed at the bottom of the filter cotton 19, and a filter screen 21 is installed at the bottom of the adsorption plate 20. In this structure, the filter cotton 19 is made of rock wool, and the adsorption plate 20 can be an activated carbon filter plate. Primarily used for filtering harmful components from gases, the filter box 5 is equipped with an air inlet pipe 1 and a drawer 9. An exhaust fan 8 is installed on the top of the drawer 9. One end of the air inlet pipe 1 is connected to the top side of the preheating chamber 4. An exhaust fan 3 is installed inside the preheating chamber 4. A partition 6 is installed between the baking chamber 17, the preheating chamber 4, and the cooling chamber 13. This device can utilize waste heat to preheat the air, thereby preheating the workpieces inside the preheating chamber 4 and shortening the subsequent drying time. Temperature and humidity control and detection mechanisms are also installed inside the baking chamber 17, the preheating chamber 4, and the cooling chamber 13. This part is a well-established and publicly available technology in this field, and therefore will not be elaborated upon here. Workpieces coated with water-based acrylic amino paint are prone to generating harmful gases during the drying process.The gas can be filtered through filter cotton 19, adsorption plate 20, and filter screen 21, improving the safety and environmental performance of this device.

[0023] Working principle: When using this water-based acrylic amino paint rapid baking device, the air discharged from the baking chamber 17 after heating first enters the filter box 5 through the second exhaust pipe 11. The heat in the air heats the air inside the air inlet pipe 1. Then the air enters the preheating chamber 4. After the workpiece that has been sprayed is placed in the preheating chamber 4, preheating begins. After preheating, the workpiece enters the baking chamber 17 under the conveyor of the chain conveyor mechanism 18. When the workpiece enters the baking chamber 17, the partition 6 opens. When the workpiece enters the baking chamber 17, it begins to dry. After drying, the workpiece is moved to the cooling chamber 13 and cooled by the cooling fan 12, thereby achieving rapid drying of the workpiece.

[0024] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
