[0021] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process, which are as follows:

[0022] According to the instruction manual Figure 1-5 It can be seen that the nozzle 5 in the utility model is arranged on the mounting seat 12 and connected to the external feeding system. This is the prior art and will not be described in detail. During the spraying operation, the driving member drives the rotating ring 1 to rotate. The side surface of the rotating ring 1 is provided with arc grooves 9 arranged in a circular matrix. The arc grooves 9 are inclined to the radial direction of the rotating ring 1. Figure 3 As shown, combined Figure 1 , 2As shown in Figures 5 and 6, the rotating ring 1 rotates counterclockwise and the arc groove 9 rotates counterclockwise. Since the outer ring baffle 3 is radially slidably connected to the end surface of the sleeve 13 through the sliding member, and the limiting column 2 on the outer ring baffle 3 is slidably connected to the arc groove 9, the rotating ring 1 and the arc groove 9 rotate counterclockwise to drive the limiting column 2, the outer ring baffle 3, and the inner ring baffle 4 connected to the outer ring baffle 3 to move radially, that is, to move outward, to achieve Figure 5 When the spraying is completed or paused, the driving member drives the rotating ring 1 to rotate clockwise, so that the time limit column 2 and the outer ring baffle 3 and the inner ring baffle 4 connected to the outer ring baffle 3 move inward to achieve Figure 2 In the state, multiple groups of inner baffles 4 and outer baffles 3 form a sector, and multiple groups of sectors can be combined into a disc shape, which cooperates with the rotating ring 1 and the sleeve 13 to form a relatively closed space, wrapping the nozzle 5, avoiding the problem of easy air drying and curing at the outlet of the nozzle 5, and avoiding blockage and affecting the spraying effect. In this process, in order to ensure the normal operation of the nozzle 5, the length of the nozzle 5 is greater than the length of the sleeve 13 connected to the mounting seat 12. At the same time, multiple inner baffles 4 are respectively fixedly connected to the outer side wall of the corresponding outer baffle 3 at the inner end, so as to leave space for the protruding part of the nozzle 5, and the design is reasonable.

[0023] Among them, the driving part includes a motor 11, a gear 10 and a ring gear 14. The ring gear 14 is rotatably sleeved on the outer wall of the sleeve 13. The end face of the ring gear 14 is fixedly connected to the side surface of the rotating ring 1. The motor 11 is fixedly set on the outer wall of the sleeve 13. The gear 10 is connected to the output end of the motor 11, and the gear 10 is meshed with the ring gear 14.

[0024] During operation, the working output end of the motor 11 drives the gear 10 to rotate. Since the gear 10 is meshed and connected with the ring gear 14, and the ring gear 14 is rotationally connected with the sleeve 13, the rotation of the gear 10 drives the ring gear 14 and the rotating ring 1 connected to the ring gear 14 to rotate, ensuring that the outer ring baffle 3 and the inner ring baffle 4 can be opened and closed subsequently.

[0025] The sliding member includes a slide bar 7, which is fixedly arranged on the side wall surface of the outer ring baffle 3 and faces the radial direction of the sleeve 13. A slide groove 8 is provided in the radial direction on the end surface of the sleeve 13 and corresponds to the position of the slide bar 7. The slide bar 7 is radially slidably connected with the slide groove 8. This structure limits the outer ring baffle 3 to ensure the stability of its movement.

[0026] Among them, rubber pads 15 are respectively arranged between the end faces of two adjacent outer ring baffles 3 and between two adjacent inner ring baffles 4, so as to improve the sealing performance of the protection of the nozzle 5 and prevent the paint from being dried by air.

[0027] In addition, a fixing rod 6 is provided between the inner wall of the sleeve 13 and the nozzle 5 to further ensure the stability of the nozzle 5 .
