[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-4The utility model provides a technical solution: a millisecond spray switching device, including a paint box 1, a rotating sleeve 8 is rotatably connected to the bottom end of the paint box 1, a delivery pipe 7 is fixedly connected to the inside of the rotating sleeve 8, and a nozzle 22 is fixedly connected to the end of the delivery pipe 7 away from the paint box 1. The lower end of the delivery pipe 7 is U-shaped, and a rotating shaft 10 is rotatably connected to the horizontal end of the delivery pipe 7. A baffle 9 is fixedly connected to the outer circumference of the rotating shaft 10. The baffle 9 is an elliptical piece, and both ends of the side are arc-processed. When the baffle 9 is tilted, the side is against the inner wall of the delivery pipe 7. Both ends of the baffle 9 are arranged through the delivery pipe 7. The penetrating parts at both ends of the delivery pipe 7 are fixedly sleeved with a rocking plate 16. The lower end of the delivery pipe 7 corresponds to the baffle 9 A mounting plate 12 is fixedly connected thereto, and a reset mechanism and a pushing mechanism are respectively provided at both ends of the mounting plate 12. The pushing mechanism is transmission-connected to one end of the rocking plate 16 on one side, and the reset mechanism is transmission-connected to one end of the rocking plate 16 on the other side. Since the paint sprayed by the rotating sleeve 8 comes from the pressure in the delivery pipe 7, when the spraying is cut off, the baffle 9 is rotated to quickly cut off the flow of paint in the delivery pipe 7. The lower end of the delivery pipe 7 is U-shaped. After the cut-off, the liquid pressure in the delivery pipe 7 disappears. After passing through the baffle 9, the paint is temporarily stored at the vertical end of the delivery pipe 7 by gravity and will not be sprayed out, thereby preventing waste, thereby improving the utilization efficiency of materials and preventing economic losses.

[0024] like Figure 1-4 As shown, the pushing mechanism includes a cylinder 15 fixedly embedded in the mounting plate 12, and the output end of the cylinder 15 is against the bottom end of its corresponding rocking plate 16. Through the movement of the output end of the cylinder 15, the output end of the cylinder 15 will lift one side of the rocking plate 16, thereby causing the rotating shaft 10 to rotate.

[0025] like Figure 1-4 As shown, the reset mechanism includes a mounting cylinder 13 fixedly connected to the end of the mounting plate 12, and a reset spring 14 is fixedly connected inside the mounting cylinder 13. The movable end of the reset spring 14 is fixedly connected to the bottom end of its corresponding rocking plate 16. When spraying continues, the cylinder 15 resets, and the rocking plate 16 is reset by the deformation recovery of the reset spring 14, and the rocking plate 16 becomes horizontal, so as not to hinder the continued flow of the liquid.

[0026] like Figure 1-4 As shown, a driven gear 18 is provided on the outer periphery of the rotating sleeve 8, a rotating pin 17 is rotatably connected to the bottom end of the paint box 1, and a matching gear 20 is fixedly connected to the outer periphery of the rotating pin 17. A driving motor 6 is fixedly installed on the side end of the paint box 1, and a driving gear 19 is fixedly connected to the output end of the driving motor 6. The driving gear 19 is meshed with the matching gear 20 for transmission connection, and the matching gear 20 is meshed with the driven gear 18 for transmission connection. The driving motor 6 can cooperate with the driving gear 19, the matching gear 20 and the driven gear 18 to drive the conveying pipe 7 to rotate, so that the device can perform rotational spraying and increase the spraying area.

[0027] like Figure 1-4 As shown, two symmetrically distributed mounting brackets 5 are fixedly connected to the side ends of the paint box 1 , and the drive motor 6 is fixedly installed inside the two mounting brackets 5 . The mounting brackets 5 serve to fix the drive motor 6 .

[0028] like Figure 1-4 As shown, the side end of the paint box 1 is fixedly connected to an input pipe 11, and the end of the input pipe 11 is fixedly connected to a connecting flange 21. Paint can be output into the paint box 1 through the input pipe 11, and the connecting flange 21 is convenient for connection with an external input pipeline.

[0029] like Figure 1-4 As shown, a control panel 2 is fixedly embedded in the side end of the paint box 1. The control panel 2 is electrically connected to the drive motor 6 and the cylinder 15, so as to facilitate the regulation of the electrical appliances of various parts of the device.

[0030] like Figure 1-4 As shown, a fixing plate 3 is fixedly connected to the top of the paint box 1 , and mounting holes 4 are opened at the four corners of the fixing plate 3 , and the device can be installed through the fixing plate 3 and the mounting holes 4 .

[0031] Working principle: When performing thin film spraying, the paint enters the interior of the delivery pipe 7 from the paint box 1 and is output from the nozzle 22 through liquid pressure to perform the spraying operation. When the spraying is paused, the end of the cylinder 15 outputs and lifts one side of the rocker plate 16 on the side of the rotating shaft 10, thereby rotating the baffle 9 on the rotating shaft 10. After the baffle 9 rotates, the side of the baffle 9 abuts against the inner wall of the delivery pipe 7, thereby blocking the paint in the delivery pipe 7, so that the flow of paint in the delivery pipe 7 is suspended. After the cut-off, the liquid pressure in the delivery pipe 7 disappears, and the lower end of the delivery pipe 7 is U-shaped. After passing through the baffle 9, the paint will be temporarily stored at the vertical end of the delivery pipe 7 due to gravity, which can prevent excess paint from being sprayed out, reduce paint waste, thereby improving material utilization efficiency and preventing economic losses.

[0032] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
