DETAILED DESCRIPTION

[0020] The following is combined with Figure 1-3 The utility model is described in further detail.

[0021] In this embodiment, an environmentally friendly painting device for metal castings solves the problem that the nozzles of existing casting painting devices are mostly fixed and cannot be adjusted according to the height requirements of the castings to meet the painting requirements. The device includes:

[0022] The paint box 1 includes a paint tank 2 fixedly mounted on the top of the paint box 1, a drive motor 3 fixedly mounted on the top of the paint box 1, and a bottom power output end of the drive motor 3 extends into the inner cavity of the paint box 1, and the bottom power output end of the drive motor 3 is rotatably connected to the paint box 1;

[0023] A driving gear 5 is fixedly installed at the bottom power output end of the driving motor 3, and the driving gear 5 is located in the inner cavity of the paint box 1. A hollow shaft 6 is rotatably connected at the top center of the paint box 1, and the top of the hollow shaft 6 extends into the inner cavity of the paint tank 2, and the bottom of the hollow shaft 6 extends into the inner cavity of the paint box 1. A stirring disk 7 is fixedly installed on the circumferential outer wall of the hollow shaft 6 through a connecting frame, and a stirring shaft 8 is fixedly installed on the top of the stirring disk 7;

[0024] A turntable 9 is fixedly installed at the bottom of the hollow shaft 6, and a support frame 10 is fixedly installed at an equal angle on the outer wall of the circumference of the turntable 9. A paint toothed disc 11 is fixedly installed on the outside of the turntable 9 through the support frame 10, and the paint toothed disc 11 is meshed with the driving gear 5. A connecting pipe 12 connected to the hollow shaft 6 is fixedly installed on the top of the support frame 10. A micro motor 13 is fixedly installed on the top of the paint toothed disc 11, and the micro motor 13 is installed at one end of the support frame 10 with the connecting pipe 12 installed on the top. A lifting frame 14 is fixedly installed at the bottom of the paint spraying toothed disc 11, and a threaded rod 15 is rotatably installed in the inner cavity of the lifting frame 14, and the top of the threaded rod 15 is fixedly connected to the power output end of the bottom of the micro motor 13. The circumferential outer wall of the threaded rod 15 is threadedly connected to a lifting seat 17, and a paint pump 18 is fixedly installed on the lifting seat 17 close to the center of the turntable 9. The paint pump 18 is connected to the connecting pipe 12 through a hose, and a paint spray nozzle 19 is fixedly installed on the side of the paint pump 18 away from the lifting seat 17.

[0025] Adopting the above-mentioned scheme: when the present application is in use, the driving motor 3 drives the paint spray toothed disc 11 to rotate through the driving gear 5, so that the lifting frame 14 rotates accordingly, and the threaded rod 15 is driven to rotate by the micro motor 13, so that the lifting seat 17 is lifted and lowered in the inner cavity of the lifting frame 14 to adjust the height of the paint spray nozzle 19, and the position of the paint spray nozzle 19 can be continuously adjusted during the painting work to meet the painting work, so that the painting work of the metal casting is more comprehensive.

[0026] When the turntable 9 rotates along with the paint spraying tooth disc 11, the hollow shaft 6 also rotates accordingly. The hollow shaft 6 is connected to the paint box 1 and the paint tank 2 through a sealed bearing, and the top of the hollow shaft 6 is located at the bottom of the inner cavity of the paint tank 2. In this way, the paint in the paint tank 2 can be transported to the connecting pipe 12 through the hollow shaft 6 under the action of its own gravity, and then transported to the paint spraying pump 18 through a hose, and finally sprayed out through the paint spray nozzle 19 to paint the metal casting. When the paint spraying nozzle 19 rotates along with the paint spraying tooth disc 11 to spray the metal casting, the hollow shaft 6 will also rotate with the stirring disc 7, and the paint can be stirred by the stirring disc 7 and the stirring shaft 8.

[0027] It should be supplemented that a circular rail groove 4 is provided at the bottom of the inner cavity of the paint box 1 , and a guide wheel 16 matching the circular rail groove 4 is installed at the bottom of the lifting frame 14 .

[0028] With the above solution, when in use, the cooperation between the annular rail groove 4 and the guide wheel 16 can enable the lifting frame 14 to rotate stably, thereby ensuring that the paint spraying nozzle 19 can perform the painting operation stably.

[0029] It should be noted that a feed port is provided on the top of the paint tank 2, and a cover is installed on the top of the feed port.

[0030] With the above solution, when in use, paint can be added to the paint tank 2 through the feed port, and the paint can be protected by the cover.

[0031] It should be supplemented that the lifting seat 17 is a rectangular parallelepiped, and the lifting seat 17 matches the inner cavity of the lifting frame 14 .

[0032] With the above solution, when in use, the lifting seat 17 does not rotate along with the rotation of the threaded rod 15 , but can be lifted and lowered along the lifting frame 14 .

[0033] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
