[0020] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Example 1

[0022] like Figure 1 - Figure 4As shown, a spraying device for the surface of an instrument panel comprises a base plate 1, two support plates 2 installed on the top of the base plate 1, and an annular box 3 installed between the two support plates 2 and having openings on the top and the bottom, the bottom of the annular box 3 is rotatably connected to a rotating table 5, a rotating mechanism for driving the rotating table 5 to rotate is installed on the top of the base plate 1, the rotating mechanism comprises a rotating column 4 rotatably connected to the top of the base plate 1, a driven wheel 6 installed on the outside of the rotating column 4, a rotating motor 7 installed on the top of the base plate 1, and an arc gear 8 installed on the output end of the rotating motor 7 and used in conjunction with the driven wheel 6, the top of the rotating column 4 is fixedly connected to the bottom of the rotating table 5, a plurality of fixing mechanisms are installed on the top of the rotating table 5, and the fixing mechanisms are located in the annular box 3, a spraying mechanism is installed inside the annular box 3, the spraying mechanism comprises a spray box 24 installed on the inner walls of both sides of the annular box 3, a plurality of spray heads installed on one side of the spray box 24, and a spraying assembly installed on the top of the base plate 1, the spraying assembly comprises an installation A liquid tank 10 is mounted on the top of the base plate 1, and an extraction pump 11 is mounted on one side of the liquid tank 10. The inlet of the extraction pump 11 is connected to the liquid tank 10 through a liquid inlet pipe, and the outlet of the extraction pump 11 is installed with a liquid outlet pipe. The interiors of the two spray boxes 24 are connected to the liquid outlet pipe through connecting pipes. The fixing mechanism includes a first fixed plate 16 mounted on the top of the rotating table 5, a rotating rod 17 rotatably connected to the top of the first fixed plate 16, a first rotating plate 21 mounted on the top of the rotating rod 17, a pneumatic cylinder 19 mounted on the top of the first fixed plate 16, a second fixed plate 20 mounted at the output end of the pneumatic cylinder 19, and a second rotating plate 23 rotatably connected to the bottom of the second fixed plate 20 and used in conjunction with the first rotating plate 21. A driving mechanism for driving the rotating rod 17 to rotate is installed inside the annular box 3. The driving mechanism includes a first ring gear 18 mounted on the outside of the rotating rod 17, and a second ring gear 22 mounted on the inner side of the annular box 3 and meshing with the first ring gear 18.

[0023] It should be noted that, when using the device for spraying the surface of the instrument panel, the instrument panel to be sprayed is placed between the first rotating plate 21 and the second rotating plate 23, and the pneumatic cylinder 19 drives the first fixed plate 16 to move downward, and the second rotating plate 23 is driven by the first fixed plate 16 to move downward, so that the instrument panel can be fixed between the first rotating plate 21 and the second rotating plate 23, and then the rotating motor 7 is started, and the rotating motor 7 drives the arc gear 8 to rotate. When the arc gear 8 is engaged with the driven wheel 6, it drives the rotating column 4 to rotate, thereby driving the rotating table 5 to rotate. When the rotating table 5 rotates, the fixed instrument panel is moved between the two spray boxes 24. At this time, the extraction pump 11 draws the spray liquid in the liquid tank 10 into the spray box 24. Then it is sprayed on the outer surface of the dashboard through multiple nozzles. When the rotating table 5 rotates, it will drive the rotating rod 17 to rotate. Under the engagement of the first ring gear 18 and the second ring gear 22, the first rotating plate 21 and the second rotating plate 23 will drive the dashboard to rotate, so that the dashboard can be sprayed in all directions. Since multiple fixing mechanisms are installed on the top of the rotating table 5, multiple dashboards can also be fixed on multiple fixing mechanisms respectively, so that multiple dashboards can be processed at the same time. Since a placement port is opened on one side of the annular box 3, the dashboard can be conveniently fixed and disassembled, and due to the cooperation of the arc gear 8 and the driven wheel 6, the rotating table 5 can have intermittent dwell time during the rotation process, so that it is more convenient for workers to fix and disassemble the dashboard.

[0024] Example 2

[0025] like Figure 1 - Figure 4 As shown, a spray-painting device for the surface of an instrument panel, a drying mechanism is installed inside the annular box 3, the drying mechanism includes a drying box 9 installed on the inner walls of both sides of the annular box 3, a plurality of air outlet hoods installed on one side of the drying box 9, a blower 12 and a heating box 13 installed on the outside of the annular box 3, and a plurality of heating tubes 14 installed inside the heating box 13, the air inlet of the blower 12 is connected with the heating box 13 through the air inlet pipe, the top of the heating box 13 is installed with an air outlet pipe, and the top of the drying box 9 is connected with the air outlet pipe through a connecting pipe, and two cover plates 15 are installed on the top of the annular box 3, and the two cover plates 15 are respectively located on the top of the spray-painting mechanism and the drying mechanism.

[0026] It should be noted that when the plastic spraying device for the surface of the dashboard is in use, the dashboard after spraying is moved between two drying boxes 9. At this time, the blower 12 will generate wind, and the wind will enter the interior of the heating box 13 and be heated by the heating tube 14. The heated wind will enter the two drying boxes 9 and finally be blown out through multiple air outlet hoods, so that the dashboard after plastic spraying can be dried, thereby improving the efficiency of dashboard processing.

[0027] The above embodiments only express several implementation methods of the utility model, which are described in more detail, but cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
