[0002] A dining table is a piece of furniture used for dining in a home or restaurant. It is usually flat, rectangular or round, and supported by legs. It is not only a space for dining, but also an important place for family and friends to gather and communicate. During production, a coating device is usually used to coat the dining table with some protective materials. The coating materials and processes vary according to different design requirements, usage scenarios, and cost considerations, but generally speaking, the main purpose of coating a dining table is to protect the wood surface from moisture, scratches, and wear, and to enhance its aesthetics.

[0003] The nozzles of existing coating devices are usually stored externally after use, which has poor protection effect on the nozzles, making the nozzles easily damaged by external forces. Some paint is likely to remain inside the nozzles after use, and these paints are likely to drip again and affect the environment. In addition, when coating the dining table, in order to improve the protection effect of the dining table, multiple layers of material are usually coated on the dining table. Therefore, multiple groups of nozzles are usually arranged in the device. Multiple groups of nozzles are placed flat in the device to increase the volume of the coating device. In addition, different dining tables have different sizes and shapes, which makes it inconvenient to adjust the coating area according to the size and shape of the dining table, and easily reduces the flexibility of the coating device. Summary of the invention

DETAILED DESCRIPTION

[0023] In order to further explain the technical solution of the present utility model, it is described in detail through specific embodiments below.

[0024] like Figure 1 As shown, the utility model provides a high-efficiency coating device for a dining table, comprising a support frame 1, an electric slide rail 2 horizontally mounted on the support frame 1, a cross bar 8 horizontally locked and fixed to the bottom of the inner side of the support frame 1, and an electric slider 3 mounted on the electric slide rail 2, the electric slider 3 can move horizontally along the electric slide rail 2 to adjust the horizontal position of the spray head 12;

[0025] like Figures 1 to 3 As shown, in this embodiment, the electric slider 3 is vertically locked and fixed with a driving motor 4, and the bottom output shaft of the driving motor 4 vertically passes through the electric slider 3 and is connected to the middle of the top surface of the protective cover 5 in the support frame 1, so that the protective cover 5 can be controlled to rotate horizontally by the driving motor 4, so as to drive the spray head 12 to rotate horizontally to apply the coating material to the circular dining table;

[0026] The protective cover 5 is rotatably mounted with an adjustment cylinder 7, which can be rotated inside the protective cover 5 to adjust the use of different nozzles 12. An opening 6 is provided in the middle of the bottom end surface of the protective cover 5, and the opening 6 is used to discharge the paint. An adjustment motor 16 is horizontally locked and fixed in the middle of the rear end surface of the protective cover 5.

[0027] Three feeding pipes 11 are installed in an annular manner and at equal distances in the adjusting cylinder 7. A plurality of nozzles 12 for discharging paint are installed at the bottom of each feeding pipe 11. The nozzles 12 vertically penetrate the inner side of the adjusting cylinder 7, and a solenoid valve 13 is installed on the nozzles 12 to control the on and off of the paint in the nozzles 12.

[0028] The crossbar 8 is provided with an adjustment mechanism 9 for adjusting the horizontal position of the dining table;

[0029] The front output shaft of the regulating motor 16 passes through the protective cover 5 and is connected to the middle of the rear end surface of the regulating cylinder 7;

[0030] The nozzles 12 on the feed pipe 11 are equidistantly distributed, and a distance is set between the nozzles 12 and the inner wall of the protective cover 5, so that the nozzles 12 can apply the paint on the dining table more evenly, and prevent the nozzles 12 from colliding with the inner wall of the protective cover 5 when the adjusting cylinder 7 rotates;

[0031] In this embodiment, a desiccant placement frame 10 is installed on the inner wall of the protective cover 5, which is convenient for placing desiccant in the desiccant placement frame 10, which is beneficial to keeping the air inside the protective cover 5 dry and preventing moisture from corroding the nozzle 12 or affecting the spraying effect of the paint;

[0032] In this embodiment, the inner wall of the protective cover 5 is embedded with an electric heating plate 14, and the electric heating plate 14 is flush with the inner wall of the protective cover 5, which is conducive to regulating the temperature inside the protective cover 5 and the nozzle 12, preventing the excessively low temperature from affecting the performance of the nozzle 12 and the texture of the paint, and also reducing the situation where the paint solidifies inside the nozzle 12;

[0033] In this embodiment, a collecting groove 15 is provided below the nozzle 12. The collecting groove 15 is provided at the junction of the bottom wall and the side wall of the protective cover 5, and the collecting groove 15 is staggered with the opening 6, so that the paint dripping from the nozzle 12 can be collected through the collecting groove 15 to prevent the paint from polluting the environment.

[0034] In this embodiment, the driving motor 4 and the adjusting motor 16 are both made of servo motors, which receive electrical signals to control the rotation angle, thereby more accurately adjusting the rotation angle of the protective cover 5 and the adjusting cylinder 7, which is conducive to accurately adjusting the position of the nozzle 12;

[0035] The electrical device in this embodiment is connected to an external control device, which is a prior art and will not be described in detail.

[0036] When in use, the support frame 1 is installed at an appropriate position, and a table conveying device can be arranged in the support frame 1 according to actual conditions, so as to convey the table to be painted into the support frame 1 through the conveying device, and connect different feeding pipes 11 to the external paint feeding device;

[0037] When the dining table needs to be painted, the dining table can be transported to the support frame 1, and then the corresponding number of solenoid valves 13 are opened according to the size of the dining table, so that the nozzle 12 corresponding to the outermost solenoid 13 corresponds to the top edge of the dining table, and the electric slide rail 2 is controlled to drive the electric slider 3 to move horizontally, and the electric slider 3 drives the protective cover 5, the adjustment cylinder 7, and the nozzle 12 to move horizontally, and then the paint is transported into the feed pipe 11 through the external paint feeding device, and the paint passes through the feed pipe 11 and the nozzle 12 and sprayed downward onto the dining table. Since the electric slider 3 drives the nozzle 12 to move continuously, the nozzle 12 can apply the paint more comprehensively on the dining table, so that the paint can be efficiently applied on the dining table;

[0038] When other coatings need to be applied, the adjusting motor 16 can be controlled to drive the adjusting cylinder 7 to rotate, and the adjusting cylinder 7 can drive the feeding pipe 11 to rotate, so that the nozzles 12 of different groups are directly opposite to the opening 6. At this time, the coatings in different feeding pipes 11 are sprayed downward on the dining table through the corresponding nozzles 12, so as to achieve more efficient coating of multiple layers of coatings on the dining table. When the nozzles 12 are retracted, if there is residual coating in the nozzles 12, it will drip downward into the protective cover 5 for collection, and the coating can be further stably collected by the provided collecting tank 15.

[0039] When the dining table to be painted is round, the electric slide rail 2 is first controlled to move the protective cover 5 to the upper middle part facing the dining table, and then the protective cover 5, the adjustment cylinder 7 and the spray head 12 can be driven by the driving motor 4 to rotate horizontally. The spray head 12 sprays the paint onto the round dining table while rotating, thereby improving the flexibility of the coating device.

[0040] like Figure 4 As shown, in this embodiment, the adjustment mechanism 9 includes a cylinder 91 locked and fixed to the outer wall of the cross bar 8, and a movable frame 92 arranged on the inner side of the cross bar 8. The piston rod of the cylinder 91 passes through the side surface of the cross bar 8 and is connected to the movable frame 92. A plurality of guide rollers 93 are rotatably installed in the movable frame 92. The guide rollers 93 are used to guide the conveying dining table.

[0041] The outer diameter of the guide roller 93 is larger than the inner width of the movable frame 92, so that the guide roller 93 can contact the dining table and reduce the friction and wear between the dining table and the movable frame 92.

[0042] Specifically, when the position of the dining table to be coated with paint is offset, the movable frame 92 can be driven to move by controlling the air cylinder 91, and the movable frame 92 drives the guide roller 93 to move, and the guide roller 93 pushes the dining table to move, so as to adjust the position of the dining table, which is beneficial for the dining table to face the nozzle 12, so that the nozzle 12 can more accurately apply the paint to the dining table.

[0043] The above description is only a preferred example of the present invention and is not intended to limit the present invention. Although the present invention is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
