[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0023] like Figures 1-3As shown in the figure, this utility model embodiment proposes a gas collection hood for a spraying production line, comprising:

[0024] Mounting frame 1 has mounting holes at all four corners, allowing it to be fixed to the spraying production line equipment with bolts. The mounting holes, combined with high-strength bolts, ensure a stable installation, effectively preventing the equipment from loosening or shifting during operation and ensuring the safety and reliability of the overall structure.

[0025] The gas collection assembly includes a flexible gas collection cover 5 mounted above the mounting frame 1. The flexible gas collection cover 5 is flexible and can be folded and retracted. The main function of the flexible gas collection cover 5 is to form a retractable, flexible, and sealed space in the spraying production area, which can effectively isolate and collect toxic and harmful gases, volatile organic compounds, and dust and other pollutants generated during the operation, preventing them from spreading into the workshop environment and improving safety.

[0026] Support rods 2 are fixedly installed at each of the four corners of the mounting frame 1. A top plate 3 is fixedly installed on the top of the support rods 2. A ventilation pipe 10 is installed through the top plate 3. The ventilation pipe 10 is fixedly installed through the top of the gas collection cover 5 and is used for ventilation.

[0033] The brush 14 is abutted against the dustproof net 11. A guide rod 13 is fixedly installed inside the ventilation pipe 10 and is fixedly installed inside the collection box 12. The guide rod 13 slides through the brush 14 and guides the brush 14. A top rod 15 is fixedly installed at the bottom of the brush 14 and slides through the bottom of the collection box 12. A spring 16 is fixedly installed between the brush 14 and the collection box 12, so that the brush 14 and the collection box 12 are elastically connected by the spring 16. The spring 16 is made of fatigue-resistant material, with a long service life and stable performance.

[0034] The detailed working process of this utility model is as follows:

[0035] 1. When closing, first lower the gas collection soft cover 5 and multiple support frames 4 so that the sealing strip 18 abuts against the mounting frame 1; then, tighten the hook 8 through the buckle 7 to press the sealing strip 18 against the wall, and it can be used.

[0036] 2. When opening, first pry open the buckle 7 and separate it from the hook 8; then lift the multiple support frames 4 upwards and fold and retract the gas collection soft cover 5; then hook the slider 6 with the hanging ring 9 to clean or perform routine maintenance on the inside of the equipment.

[0037] 3. During the opening of the air collection cover 5, the support frame 4 will push the brush 14 upward through the top rod 15. The moving brush 14 can then brush the dustproof net 11 to clean the dust on its surface and prevent clogging.
