[0022] Specifically, place the metal or equipment coated with chromium nitride coating in the vacuum baking equipment body 1. There is a rotating placement assembly in the vacuum baking equipment body 1. The rotating disk 11 on the rotating placement assembly is used for placing the metal or equipment. After placing, close the sealing door 19. Run the vacuum pump 4 on the vacuum pumping assembly to pump out the air in the baking chamber 2, forming a vacuum state in the chamber, reducing the boiling point of water, accelerating the drying speed, and at the same time avoiding the oxidation reaction of the coating with air after heating. Then, through the heating of the heating wire 3, the placed metal or equipment can be heated and baked. The rotating placement assembly includes an installation groove 9 opened on the bottom side of the vacuum baking equipment body 1. A driving motor 10 is fixedly installed in the installation groove 9. The output end of the driving motor 10 extends into the baking chamber 2 and is fixedly installed with a rotating disk 11. During the baking process, start the driving motor 10 to drive the rotating disk 11 to rotate. Through rotation, the coating can be heated and dried more evenly, and the drying effect is better.

[0023] Specifically, the movable sealing assembly includes a sealing baffle 17 movably installed. The sealing baffle 17 seals and blocks at a position on one side of the air vent 15. A telescopic cylinder 18 is fixedly installed on one side of the vacuum baking equipment body 1. The output end of the telescopic cylinder 18 extends into the moving groove 14 and is fixedly connected to one side of the sealing baffle 17. The vacuum pumping assembly includes a vacuum pump 4 fixedly installed on one side of the vacuum baking equipment body 1. A suction pipe 5 is connected to one side of the vacuum pump 4.

Then, the sealing door 19 is opened, and at the same time, the telescopic cylinder 18 on the movable sealing assembly is started to operate, driving the sealing baffle 17 to move. After the sealing baffle 17 moves, the air vent 15 will be opened. At this time, the blower fan 16 is started to operate to generate a blowing wind to dissipate heat from the internally baked coated metal or equipment. While blowing the wind, the rotating disk 11 also continues to rotate, so as to achieve uniform blowing heat dissipation. Through blowing heat dissipation, the temperature of the baked coated metal or equipment can be quickly reduced, so that it can be quickly taken out.

Place the metal or device coated with the chromium nitride coating in the vacuum baking device body 1. Inside the vacuum baking device body 1, there is a rotating placement component. The rotating disk 11 on the rotating placement component is used for placing the metal or device. After placement, close the sealing door 19. Operate the vacuum pump 4 on the vacuum pumping component to extract the air in the baking chamber 2, creating a vacuum state in the chamber, reducing the boiling point of water, accelerating the drying speed, and at the same time avoiding the oxidation reaction of the coating with air after heating. Then, through the heating of the heating wire 3, the placed metal or device can be heated and baked. During the baking process, start the drive motor 10 to drive the rotating disk 11 to rotate. Through rotation, the coating can be heated and dried more evenly, and the drying effect is better, realizing the rapid curing of the chromium nitride coating. After drying, by opening the air release valve 7, external gas enters the baking chamber 2 through the air release pipe 6 to achieve internal and external pressure balance. Then open the sealing door 19, and at the same time start the telescopic cylinder 18 on the movable sealing component to drive the sealing baffle 17 to move. After the sealing baffle 17 moves, the air permeable holes 15 will be opened. At this time, start the blower fan 16 to operate to generate a blowing wind to dissipate heat from the coated metal or device after baking inside. While blowing, the rotating disk 11 also continues to rotate, thus realizing uniform heat dissipation by blowing. Through heat dissipation by blowing, the temperature of the coated metal or device after baking can be quickly reduced, so that it can be quickly taken out. The provided filter cover 21 can effectively block external dust and prevent dust from entering with the blowing of the blower fan 16, which is convenient to use.
