AI Technical Summary
The integrated design of existing automotive sprayed air molders leads to the need to replace the entire molded air ring when there is local damage, causing waste, and the high-speed rotation of the spray cup causes the paint particles to be unable to be evenly sprayed.
A detachable air molder is designed, including an air molder housing, nozzle and outer ring. Through the combination of internal threads, external threads and sealing rings, the nozzle and air molder housing can be replaced independently to ensure sealing.
The independent replacement of nozzle and air molder housing is achieved, reducing waste, and improving the sealing between the equipment through sealing rings and rubber magnetic stripes, ensuring spray quality.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of spraying tools, in particular to a novel air former used for automobile spraying. Background Art
[0002] The high-speed spray cup atomizer used by the paint spraying robot, the high-pressure air drives the air motor with the conical spray cup to rotate at high speed, causing the paint to flow outward from the inner wall of the spray cup, so that the paint is atomized into fine particles at the edge of the spray cup due to the centrifugal force. These paint particles are in a plane and diverge outward from the spray cup. Therefore, in this case, the paint cannot be sprayed onto the car surface, affecting the spraying quality. For this reason, the current manufacturer introduces a forming air ring on the outside of the spray cup to blow air to the atomized paint particles, blow the paint particles into a cylindrical shape, and spray them onto the car surface to be sprayed. The forming air ring is also called an air former or an air forming hood. Most of the current air formers are integrated, such as the utility model patent with the publication number CN211463551 U, which discloses a forming air ring for an atomizer. When the forming air ring is partially damaged and affects the use, the entire forming air ring needs to be replaced together, which is relatively wasteful. Utility Model Content

DETAILED DESCRIPTION
[0017] See also Figure 1-Figure 2 , a new type of air former for automobile spraying, comprising:
[0018] An air former shell 1, wherein an internal thread 16 is provided at the middle of the inner side of the air former shell 1, an external thread 17 is provided on the outer wall of the air former shell 1, an external O-ring 11 is installed below the outer wall of the air former shell 1, and an external O-ring 2 12 is installed on the outer wall of the air former shell 1 and between the external O-ring 11 and the external thread 17. When the air former shell 1 is installed with the external thread 17 and the installation part, the sealing between the air former shell 1 and the installation part can be improved by the external O-ring 11 and the external O-ring 2 12;
[0019] The nozzle 2 is detachably connected to the inside of the air former shell 1. A circle of annular grooves 13 are arranged on the outside of the top of the lower inner part of the air former shell 1. A plurality of hexagon socket screws 14 are arranged through the bottom of the annular groove 13. A plurality of screw holes 24 are arranged on the outside of the lower end of the nozzle 2. The hexagon socket screws 14 are threadedly connected with the screw holes 24 in a one-to-one correspondence. An annular rubber magnetic strip 15 is inserted inside the annular groove 13 and below the hexagon socket screw 14. The annular rubber magnetic strip 15 is attracted to the hexagon socket screw 14. The lower part of the annular rubber magnetic strip 15 protrudes from the notch of the annular groove 13. By setting the annular rubber magnetic strip 15, when the air former shell 1 is installed with the installation part by adopting the internal thread 16, the sealing between the air former shell 1 and the installation part can be improved through the annular rubber magnetic strip 15, and the annular rubber magnetic strip 15 can improve the sealing between the air former shell 1 and the installation part. One end of the strip 15 protrudes from the notch of the annular groove 13, which is convenient for pulling the annular rubber magnetic strip 15 out of the annular groove 13, and then rotating and removing the hexagon socket screw 14 to disassemble the nozzle 2 and the air former shell 1. In this way, by setting the air former shell 1 and the nozzle 2 to be detachable, the nozzle 2 can be directly replaced when the nozzle 2 is damaged, and the air former shell 1 can be replaced when the air former shell 1 is damaged, so as not to cause excessive waste. An outer O-ring 3 21 is installed above the outer wall of the nozzle 2, an outer O-ring 4 22 is installed below the outer wall of the nozzle 2, and an outer O-ring 5 23 is installed at the lower end of the nozzle 2. By setting the outer O-ring 3 21, the outer O-ring 4 22 and the outer O-ring 5 23 to be in close contact with the inner wall of the air former shell 1, the sealing between the nozzle 2 and the air former shell 1 can be improved;
[0020] The outer ring 3 is connected to the outside of the air former shell 1 through an external thread 17. An inner O-ring 31 is installed on the upper inner wall of the outer ring 3, and an outer O-ring 6 32 is installed on the outer side of the lower end of the outer ring 3. By providing the inner O-ring 31, the sealing between the outer ring 3 and the air former shell 1 can be improved, and the outer O-ring 6 32 under the outer ring 3 can improve the sealing between the outer ring 3 and the installation part.
