Air inlet pipe of coating machine
By designing threaded bosses and sealing nuts around the air inlet and outlet of the coating machine's air inlet pipe, the problem of the air inlet pipe's diameter expanding after sandblasting and cleaning is solved, achieving uniform output of the reaction gas and improving the coating effect.

AI Technical Summary
Technical Problem
After long-term use, chromium buildup in the air inlet pipe of existing coating machines causes the outlet hole diameter to expand, affecting the uniformity of the reaction gas and resulting in a decline in coating quality.
Method used
An air inlet pipe for a coating machine was designed. By setting threaded bosses around the air outlet and attaching sealing nuts, the air outlet is blocked during sandblasting to prevent abrasive from entering. At the same time, during normal use, sealing gaskets seal the air outlet to ensure uniform gas output.
Benefits of technology
This effectively prevents the vent diameter from becoming larger, ensuring uniform output of the reactive gas and improving the coating quality.

Abstract
The utility model relates to an air inlet pipe of a coating machine, which comprises a first mounting part, the first mounting part comprises a first side surface and a second side surface which are oppositely arranged, a plurality of air outlet holes are uniformly formed in the first side surface, and the air outlet holes penetrate through the first side surface and the second side surface; the first side face is provided with a circular ring which is sunken downwards around each air outlet hole, the inner diameter of the circular ring is larger than that of each air outlet hole, and an air outlet sealing boss is formed around each air outlet hole; the first mounting part and the second mounting part are fixedly connected together through a bolt to form a body part of the air inlet pipe; and the inner diameter of the sealing nut is the same as the outer diameter of the air outlet sealing boss. When a sand blasting machine is used for cleaning the air inlet pipe, the air outlet is blocked through the sealing nut, and sand blasting abrasives are prevented from entering the air outlet to increase the hole diameter.
