DETAILED DESCRIPTION

[0031] The following will be combined with the 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-9 The present invention provides a technical solution: a rotary anti-pollution valve body coating machine, Example

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, the inner top of the paint box 1 is symmetrically provided with slide rails 2, and the slide rails 2 are connected to electric sliders 3, and the electric sliders 3 are connected to the load-bearing top plate 4 on the side away from the slide rails 2, and the load-bearing top plate 4 is connected to the load-bearing bottom plate 6 through a suspension rod, and a first motor 5 is installed between the load-bearing bottom plate 6 and the load-bearing top plate 4, and the first motor 5 is connected to the rotating rods 8 on both sides through a belt transmission structure 7.

[0034] In a further embodiment, a slide seat 42 is symmetrically arranged on the front side wall of the coating box 1 , and a box door 43 is slidably connected to the slide seat 42 .

[0035] Specifically, the painting box 1 and the box door 43 can prevent the paint from being sprayed and scattered to the outside during the spraying process, thereby preventing the paint from polluting the external environment.

[0036] In a further embodiment, the first motor 5, the belt transmission structure 7 and the rotating rod 8 constitute a rotating structure.

[0037] Specifically, the first motor 5 can drive two sets of rotating rods 8 to rotate simultaneously through the belt transmission structure 7. At the same time, the rotating rotating rods 8 will drive the rotating spray pipe 21 and the valve body to rotate, thereby facilitating the first spray pipe 11 to perform rotational spraying on the valve body.

[0038] like Figure 1 , Figure 4 , Figure 5 and Figure 7 As shown, the bottom of the rotating rod 8 passes through the fixed plate 9 and is connected to one end of the hydraulic cylinder 20, and the other end of the hydraulic cylinder 20 is connected to the rotary spraying pipe 21. At the same time, a telescopic component is connected to the outer wall of the rotary spraying pipe 21, a drying component is connected to the rear side of the coating box 1, and a mobile feeding component is installed in the coating box 1, and the mobile feeding component is arranged below the rotary spraying pipe 21.

[0039] In a further embodiment, the top of the rotating rod 8 passes through the bearing top plate 4 and is rotatably connected to the bearing bottom plate 6 , and the rotating rod 8 is rotatably connected to the fixing plate 9 .

[0040] In a further embodiment, the telescopic assembly includes an electric telescopic rod 22, and the electric telescopic rod 22 is distributed in a circular array on the outer surface of the rotary spray pipe 21, and one end of the electric telescopic rod 22 away from the rotary spray pipe 21 is connected to the connecting block 23, and the other side of the connecting block 23 is connected to a miniature spherical foot 24.

[0041] like Figure 1 , Figure 4 , Figure 5 and Figure 7 As shown, the bottom of the fixed plate 9 is connected to the first spray pipe 11 and the mounting seat 12 through the fixing frame 10, and a motor 13 is installed in the mounting seat 12, and the output end of the motor 13 is connected to the mounting plate 15 through the rotating plate 14, and the second spray pipe 16 and the third spray pipe 17 are connected to the side of the mounting plate 15 away from the rotating plate 14, and the second spray pipe 16, the third spray pipe 17, the first spray pipe 11 and the rotating spray pipe 21 are all connected to the spray head 18, and the second spray pipe 16, the third spray pipe 17, the first spray pipe 11 and the rotating spray pipe 21 are all connected to the material pump 40 in the paint box 39 through pipe connectors.

[0042] In a further embodiment, the motor 13, the rotating plate 14, the mounting plate 15, the second spray pipe 16 and the third spray pipe 17 constitute a rotating structure, and the second spray pipe 16, the third spray pipe 17, the first spray pipe 11 and the rotating spray pipe 21 are all connected to the pipe connector through the delivery pipe 19, and an electric valve 41 is correspondingly arranged on the delivery pipe 19.

[0043] Preferably, a box cover is snapped on the top of the paint box 39, and the paint box 39 is arranged on the top of the paint box 1. At the same time, the material pump 40 can transport the paint in the paint box 39 to the second spray pipe 16, the third spray pipe 17, the first spray pipe 11 and the rotary spray pipe 21 through the delivery pipe 19, and spray the paint onto the valve body through the nozzle above them. At the same time, the electric valve 41 can block the spray of paint when the corresponding spray pipe is not in use, thereby facilitating the classified control of multiple groups of spray pipes.

[0044] Specifically, the mobile feeding assembly drives the valve body to be coated on the top thereof to move inward in the same direction, so that the third spraying pipe 17 can be used to spray the top of the valve body during the movement, and then the hydraulic cylinder 20 drives the cylindrical rotating spraying pipe 21 to move downward and extend into the interior of the valve body to spray the interior of the valve body. After spraying, the electric telescopic rod 22 on the outer side of the rotating spraying pipe 21 pushes the micro spherical foot 24 to contact the inner wall of the valve body, and at the same time the hydraulic cylinder 20 is reset, so that the valve body after the inner wall is sprayed can be moved upward away from the mobile feeding assembly, and then the motor 1 3 drives the second spray pipe 16 to rotate to the bottom of the valve body, so that the bottom of the valve body can be sprayed, and the first spray pipe 11 located on one side of the valve body can spray the outer surface of the rotating valve body. After the spraying is completed, the electric slider 3 can be controlled to transfer the valve body to the inside of the drying component for drying. In summary, the device can spray the inner and outer side walls of the valve body at one time without the need for secondary re-coating. At the same time, since the spraying process of the device is placed in a closed box throughout the process, it can prevent the paint from polluting the external environment to a certain extent.
