[0002] Billboards are a broad term encompassing all outdoor media that convey advertising information. Their size depends on the specific environment. Shop signs, storefronts, and facades can be hand-drawn, computer-generated, or printed on paper. Billboards are widely used and ubiquitous in people's lives. Spray painting is one of the processing steps for billboards. It involves spraying paint onto the surface of the billboard, and this process requires specialized spray painting equipment for billboard processing.

[0003] A portable billboard painting device disclosed in publication number CN216704759U includes a fixed plate. A frame is fixedly connected to the top of the fixed plate near the front center. Several first spray nozzles are fixedly connected to the top of the inner cavity of the frame. A motor is located at the center of the right side of the frame. A first transmission rod is fixedly connected to the motor's power output shaft. The left end of the first transmission rod passes through the right side of the frame, and a third grooved wheel is fitted on the outer edge of the right end of the first transmission rod. Through the cooperation of the motor, the first transmission rod, and the first rotating rod, the billboard can be painted, and then dried after painting. Compared with the prior art, this increases the painting speed of the billboard, and the drying function after painting reduces the workload of the operator. This utility model, through a series of structural features, makes the device mobile and easy to use.

[0004] However, this type of spray painting device for billboard processing has the following disadvantages: during the process of spraying paint on the billboard, it is not easy to spray paint evenly on the surface of the billboard, resulting in the first and second coats of paint not overlapping, which affects the progress of the billboard painting work. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a highly practical, simple-to-operate, and structurally simple spray painting device for billboard processing. This solves the problem mentioned in the background art that it is not easy to evenly spray paint onto the surface of the billboard during the process of spraying paint, resulting in the first and second coats of paint not overlapping and affecting the progress of the billboard painting work.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a spray painting device for billboard processing, comprising a positioning rod, with connecting rods fixedly connected to both ends of the positioning rod, an L-shaped rod fixedly connected to the middle of the surface of the connecting rod, an overlapping plate fixedly connected to the bottom of the L-shaped rod, a positioning assembly threaded through the middle of the top surface of the L-shaped rod, an electric guide rail fixedly connected to the middle of the top surface of the positioning rod, an electric slider slidably connected inside the electric guide rail, a support rod provided on the top of the electric slider, a paint box fixedly connected to one end of the support rod, and a spraying assembly provided on the front of the paint box.

[0007] Optionally, the positioning component includes a screw threaded through the middle of the top surface of the L-shaped rod, and an abutment block is rotatably connected to the bottom of the screw.

[0008] Optionally, the spraying assembly includes a paint pump located in the center of the front of the paint tank, with the input end of the paint pump inserted into the interior of the paint tank, the output end of the paint pump connected to an output pipe, and one end of the output pipe connected to a spray pipe.

[0009] Optionally, the bottom of the spray pipe is provided with equally spaced circular grooves, and an atomizing nozzle is provided inside the circular groove.

[0010] Optionally, an injection hole is provided in the middle of the top surface of the pigment box, and a plug is threaded into the inside of the injection hole.

[0011] Optionally, an observation window is provided on one side of the surface of the pigment box, and a transparent plate is embedded in the surface of the observation window.

[0012] This utility model provides a convenient spray painting device for billboard processing, which has the following beneficial effects:

[0013] 1. This automatic billboard painting device, through the coordinated design of positioning rods, spraying components and paint tanks, allows personnel to automatically spray paint billboards. When the billboard needs to be painted, the personnel can turn on the power to the electric slider, which will move the support rod and paint tank. Then, the power to the paint pump will be turned on, allowing the paint pump to deliver the paint from the paint tank to the spray pipe. The atomizing nozzles will then evenly spray the paint onto the surface of the billboard, thus achieving the function of automatic paint spraying.

[0014] 2. This convenient billboard painting device, through the setting of positioning components and overlapping plates, allows personnel to place the billboard on top of the overlapping plate when they need to paint it. Then, the personnel turn the screw to move the contact block downward, so that the contact block fixes the billboard, thereby fixing the billboard and reducing the occurrence of positional displacement during the billboard painting process.
