Description

Technical Field

[0001] This utility model relates to the field of spraying equipment technology, and in particular to a spraying device for the surface of a sealing gasket. Background Technology

[0002] Gaskets are sealing elements used in the connection of machinery, equipment, and pipelines. They are usually made of rubber, metal, and composite materials. The main structures are mostly sheet-like, ring-shaped, and irregularly shaped. Some have grooved or raised sealing lips to enhance the fit. Their working principle is to fill the gaps in the connection surface by deforming themselves, blocking the fluid leakage path and achieving a seal. They are widely used in automotive engines, pipeline valves, hydraulic systems, and pressure vessels. In the chemical, energy, and machinery manufacturing industries, they play a key role in preventing media leakage and ensuring the safe operation of equipment.

[0003] During the production of gaskets, a surface spraying device is required to uniformly spray an anti-stick and wear-resistant coating onto the surface of rubber gaskets to improve their performance. Existing surface spraying devices typically use a feeding mechanism to send the gaskets to the pretreatment area for dust removal. After being fixed by positioning fixtures, they enter the spraying area, where a spray gun sprays the coating along a preset trajectory. The feeding device supplies the coating simultaneously, and then the gaskets are sent to the drying and curing area to set the coating before being discharged. However, the existing spraying devices result in uneven and incomplete coverage of the gaskets in a single spray, leading to reduced production quality and decreased production efficiency.

[0022] Working principle: When the device is working normally, switch 14 is turned on first, so that motor 21 starts to rotate, which in turn drives gear 7 to rotate, which in turn drives gear 6 to rotate, so that spray pipe 8 and spray nozzle 9 rotate together, so that the sealing gasket is uniformly sprayed in the first round, and then enters the interior of the annular pipe 11. Then, the sealing gasket is fully sprayed in the second round through the small holes of spray pipe 10 and dispersing net 12, which makes the sealing gasket more uniform and comprehensive, and improves the practicality of the device. When clamping and spraying the sealing gasket, first move the handle 212 upwards, thereby causing the limiting block 210 to rotate within the slide groove 209. Then, insert the sealing gasket into the inner wall of the limiting ring 208. Next, move the handle 212 downwards, causing the limiting block 210 to rotate, thereby locking and closing the limiting ring 208, so that the sealing gasket is placed on the inner wall of the limiting ring 208. Then, slide the slider 202 on the outer wall of the guide rail 201 to the middle of the fixed ring 5. Finally, the output end of the air pump 207 drives the limiting ring 208 and the sealing gasket to move up and down, so that they are evenly sprayed, improving practicality.
