[0002] Sealing gaskets are sealing spare parts used in machinery, equipment, and pipelines as long as there is fluid. They have a wide range of uses. In order to meet the ever-increasing usage requirements in practice, a layer of high-temperature anti-friction coating will be coated on the surface of the gasket during the production process of the sealing gasket. This coating can form an insulating film at the location of the sealing gasket, reduce the heat conduction and friction of the adjacent structures, and thus extend the service life.

[0032] Working principle:

[0033] Embodiment 1

[0034] The sealing gasket 3 is horizontally sleeved outside the middle of the support socket 4 through its own mounting hole. Then, the long screw inside the pressure regulating rod 6 is rotated, and then the long screw drives the pressing ball to synchronously press one end of the four ball head rods 52. Then, the four ball head rods 52 are pressed to drive the pressing arc plates 51 connected to them to move synchronously until the surfaces of the four pressing arc plates 51 are all in contact with and clamp the inner wall of the mounting hole, so as to clamp and fix the sealing gasket 3.

[0035] After the installation of the sealing gasket 3 is completed, the two inverted L-shaped plates 7 are used to make them respectively fit and connect with the magnetic adsorption surface of the electromagnetic chuck 9 and align with the constraint rod 14. The electromagnetic chuck 9 is started, and the electromagnetic chuck 9 magnetically limits the corresponding inverted L-shaped plate 7 to realize the preliminary installation of the sealing gasket 3 on the top of the base 1. Subsequently, the second electric push rod 15 is started, and the output end of the second electric push rod 15 drives the constraint rod 14 to be clamped in the positioning hole on the corresponding inverted L-shaped plate 7.

[0036] Start the first electric push rod 13. The output end of the first electric push rod 13 drives the support frame plate 10 and the related structures of the support frame plate 10 to move towards the top surface at the rear end of the sealing gasket 3 until all fifteen paint spray nozzles 11 are located on the top surface at the rear end of the sealing gasket 3. Then, use the existing pump and transportation equipment to automatically pump the paint into the material conveying pipe. Finally, spray the top surface where the rear end of the sealing gasket 3 is located through the fifteen paint spray nozzles 11. At the same time, start the brake servo motor 8. The output end of the brake servo motor 8 drives the support sleeve seat 4, the sealing gasket 3, the clamping rod member 5, the pressure regulating rod member 6, and the two inverted L-shaped plates 7 to rotate synchronously through the electromagnetic chuck 9, so as to achieve the full spraying of the top surface of the sealing gasket 3;

[0037] After the spraying of the top surface of the sealing gasket 3 is completed, turn off the brake servo motor 8 and the second electric push rod 15, then turn off the electromagnetic chuck 9 and the first electric push rod 13, take out the sealing gasket 3 and the support sleeve seat 4 and turn them 180 degrees so that the bottom surface of the sealing gasket 3 faces up. Then, repeat the operation according to the above steps. That's it.

[0038] Embodiment 2

[0039] When the sealing gasket 3 horizontally limited and installed in Embodiment 1 needs to be further adjusted, push the two leveling sleeve plates 18. The two leveling sleeve plates 18 can move relative to each other in a sleeved manner under the support of their respective corresponding extension support plates 17 and slide rail frames 16 to level the two sides of the sealing gasket 3 in the clamped and limited state, ensuring the flatness of the sealing gasket 3 during the spraying process. After completion, reset and move the two leveling sleeve plates 18, and continue according to the spraying steps of Embodiment 1. That's it.
