[0024] Embodiment 2

[0025] like Figure 2 and Figure 3 As shown, the vacuum adsorption powder spraying device proposed by the utility model is compared with the first embodiment.

[0026] In this embodiment, the motor drives the gear 504 to rotate so that the gear ring 505 meshing with it rotates, thereby driving the sealing seat 503 to rotate along the mounting plate 502. At this time, the tubular substrate is clamped between the two groups of sealing seats 503. Since the second mixing tube 506 is rotatably connected to the corresponding sealing seat 503 and is connected to the corresponding mounting plate 502 through the bracket 507, the feeding of the second mixing tube 506 will not be interfered with when the sealing seat 503 rotates. While the inner wall of the tubular substrate is sprayed by the second spray tube at the output end of the second mixing tube 506, the tubular substrate rotates with the sealing seat 503, which not only improves the spraying uniformity of the second spray tube, but also the first spray tube at the output end of the first mixing tube 402 can evenly and comprehensively spray the outer wall of the tubular substrate, further improving the spraying efficiency.
