Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings:

[0016] Referring to the attached diagram: The air intake and exhaust device of this coating machine includes an air intake duct 1 and an exhaust duct 2 assembled together. The air intake duct 1 is provided with a pipe cover 3 that is combined with the exhaust duct 2 to assemble the air intake duct 1 and the exhaust duct 2 together. Both the air intake duct 1 and the exhaust duct 2 have an air inlet end and an air outlet end. An adjustment component 4 is provided on the air intake duct 1 to adjust the air volume of the air intake duct 1. The principle of this utility model is that the pipe cover 3 is a connecting component that can be connected to both the air inlet pipe 1 and the air outlet pipe 2, so that the air inlet pipe 1 and the air outlet pipe 2 can be assembled together. This makes it convenient to disassemble the air inlet pipe 1 during subsequent maintenance, and also allows for full welding and polishing treatment inside and outside the pipe. The air inlet end of the air inlet pipe 1 is located outside the coating machine and the air outlet end is located inside the coating machine. It delivers the outside air to the inside of the coating machine through the air inlet end. The air inlet end of the air outlet pipe 2 is located inside the coating machine and the air outlet end is located outside the coating machine. It is used to discharge the waste air used inside the coating machine. The adjusting component 4 acts on the air inlet pipe 1 to adjust the air volume of the air inlet pipe 1, so as to adapt to different production volumes.

[0017] The air outlet of the air inlet duct 1 is formed on the outer circumferential surface of the air inlet duct 1. The adjustment component 4 is set on the outer circumferential surface of the air inlet duct 1 and covers the air outlet. The air volume is limited by the coverage area of ​​the adjustment component 4. The air outlet of the air inlet duct 1 is an opening formed on its outer circumferential surface. The adjustment component 4 is also set on its outer circumferential surface and is movable. This makes the method of controlling the air volume simple, that is, changing the position of the adjustment component 4 to adjust its coverage area of ​​the opening, and also to control the exposed area of ​​the opening, which is convenient and quick.

[0018] The adjustment component 4 includes a baffle 41 and two first connecting bolts 42. The first connecting bolts 42 are detachably connected to the air inlet duct 1. The baffle 41 has an arc-shaped configuration and forms a sliding groove 411 that matches the position and number of the first connecting bolts 42. The first connecting bolts 42 slide in the sliding groove 411. This arrangement can both cover and block the opening and achieve adjustment, that is, through the first connecting bolts 42 and the sliding groove 411. After the baffle 41 is adjusted in position, the first connecting bolts 42 are tightened to maintain the working position of the baffle 41.

[0019] The air inlet duct 1 includes a main pipe section 11 and a secondary pipe section 12. The air inlet end is located on the main pipe section 11, and the air outlet end, the first connecting bolt 42, and the baffle 41 are all located on the secondary pipe section 12. A connecting lug 5 is provided at the end of the main pipe section 11 near the secondary pipe section 12, and a sealing plate 121 is provided at the end of the secondary pipe section 12 away from the main pipe section 11. A second connecting bolt 6 is provided on the sealing plate 121, and the second connecting bolt 6 is combined with the connecting lug 5. This arrangement allows the secondary pipe section 12 of the air inlet duct 1 to be replaced. The replacement is to allow the selection of a secondary pipe section 12 with a larger or smaller opening width according to the production volume, because the control of air volume plays a crucial role in production, and the connection between the two is convenient. That is, the assembly and connection of the main pipe section 11 and the secondary pipe section 12 can be achieved by combining the second connecting bolt 6 and the connecting lug 5.

[0020] The connecting lug 5 includes a bolt connecting ring 51 and two pipe wall connecting blocks 52. One end of the pipe wall connecting block 52 is fixedly connected to the pipe wall of the main pipe section 11, and the other end is fixedly connected to the bolt connecting ring 51. The bolt connecting ring 51 is detachably connected to the second connecting bolt 6. This arrangement allows the connecting lug 5 to be stably installed on the main pipe section 11 and to be connected to the second connecting bolt 6, thereby ensuring a stable connection between the main pipe section 11 and the secondary pipe section 12.

[0021] The pipe cover 3 is made of rubber. The rubber material allows the pipe cover 3 to generate resistance when it is installed on the air inlet duct 1. Furthermore, the inner diameter of the insertion hole of the pipe cover 3 through which the air inlet duct 1 passes is slightly smaller than the outer diameter of the air inlet duct 1. This further increases the connection stability between the air inlet duct 1 and the pipe cover 3, and also ensures the sealing performance. At the same time, the pipe cover 3, when installed on the exhaust duct 2, can also increase the connection stability between it and the exhaust duct 2 by utilizing its own characteristics, and also ensure the sealing performance.

[0022] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
