Description

Technical Field

[0001] This utility model belongs to the field of advertising production technology, and in particular relates to a spray painting device for billboard production. Background Technology

[0002] Billboards are important tools for commercial advertising, information dissemination, or brand promotion. They are usually placed in densely populated areas, streets, shopping malls, airports, or other prominent locations. During the production of billboards, in order to increase their aesthetics and weather resistance, the wooden and metal parts of the billboards are usually painted.

[0003] A search revealed that patent announcement number CN221387020U, published on July 23, 2024, discloses a painting device for manufacturing anti-corrosion billboards. The device includes a spray painting table with a spray painting groove at its upper end. Vertical plates are fixedly connected to the left and right sides of the lower wall of the spray painting groove. Two fixing mechanisms are fixedly connected to the opposite surfaces of the two vertical plates. Support plates are fixedly connected to the left and right sides of the upper end of the spray painting table. A drive seat is fixedly connected to the upper end of the two support plates. A painting mechanism is fixedly connected to the upper end of the drive seat. A motor is fixedly installed on the right end of the drive seat, and a threaded rod is fixedly connected to the output end of the motor. This invention, a painting device for manufacturing anti-corrosion billboards, fixes the side of the billboard, ensuring the upper part of the billboard is unobstructed. This allows for complete painting of the billboard, avoiding secondary manual touch-ups, improving the efficiency and quality of painting anti-corrosion billboards.

[0004] Existing technology uses a motor to move multiple nozzles to spray paint billboards. However, when the billboard is small, some paint is sprayed onto the surface of the spray booth, resulting in paint waste. At the same time, during the spraying process, some paint is blown into the operating environment by the airflow, causing pollution. Furthermore, the existing technology causes paint to settle after being left to stand for a long time, which reduces the spraying effect. To address these issues, we provide a spray painting device for billboard production. Utility Model Content

[0005] The purpose of this utility model is to provide a spray painting device for billboard production. Through the cooperation of motor one and motor two, the spray nozzle can move along the part of the billboard to be painted. By using a fan and filter plate, the scattered paint is collected and filtered. In addition, motor three rotates the stirring rod to stir the paint to prevent sedimentation. This solves the problems of existing technology where, when the billboard size is small, some paint is sprayed onto the surface of the spray table, resulting in paint waste. At the same time, during the spraying process, some paint is scattered into the operating environment with the airflow, causing pollution to the operating environment. Furthermore, in the existing technology, if the paint is left to stand for a long time, sedimentation will occur, reducing the spraying effect.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a spray painting device for billboard production, comprising a spray painting frame, which includes a housing.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1

[0029] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model relates to a spray painting device for billboard production, comprising a spray painting frame 1, which includes a housing 102 with an open upper side. The housing 102 has a placement plate 103 inside. During spray painting, the billboard is placed on the upper surface of the placement plate 103. A C-shaped movable plate 104 is slidably connected to the outside of the placement plate 103. A second motor 109 is located behind the movable plate 104. A second screw 109a is fixed to the power output shaft of the second motor 109. When the second motor 109 operates, it drives the second screw 109a to rotate, thereby moving the vertical plate 104a and the movable plate 104. A U-shaped plate 106 is fixed to the upper wall of the movable plate 104. A motor 101 is fixedly mounted on the right wall of the U-shaped plate 106. A screw 101a is fixed on the power output shaft of the motor 101. When the U-shaped plate 106 moves, it drives the nozzle 201b to move back and forth. When the motor 101 is working, it drives the screw 101a to rotate, which in turn drives the moving block 105a to move, thereby driving the nozzle 201b to move in the left and right directions. A filter plate 108 is provided inside the box 102. The filter plate 108 can be an activated carbon filter plate to adsorb and filter the paint, or it can be paint filter paper. A fan 110 is fixedly mounted on the lower wall of the box 102 so that the paint that has not been sprayed onto the billboard enters the box 102 and passes through the filter plate 108.

[0030] Specifically, both ends of the left wall and both ends of the right wall of the placement plate 103 are provided with connecting plates 102a that are fixed to the box body 102. A rectangular groove 102c is provided on the right wall of the box body 102. A side plate 107 that is detachably fixed to the box body 102 is provided on the right side of the rectangular groove 102c. By removing the side plate 107, the rectangular groove 102c can be exposed. At this time, the filter plate 108 can be taken out and replaced by reaching into the box body 102.

[0031] The screw 101a is externally threaded with a movable block 105a that is slidably connected to the U-shaped plate 106. The lower wall of the movable block 105a is fixed with an electric push rod 105, which is used to drive the nozzle 201b to move up and down accordingly, thereby adjusting the height of the nozzle 201b.

[0032] The screw 109a is externally provided with a vertical plate 104a fixed to the moving plate 104. The screw 109a is threadedly connected to the vertical plate 104a. Both ends of the screw 109a are externally provided with end plates 103a fixed to the placement plate 103. The screw 109a is rotatably connected to the end plates 103a through bearings. The motor 109 is fixedly connected to the corresponding end plates 103a. With the above configuration, when the screw 109a rotates, it drives the vertical plate 104a to move, thereby causing the moving plate 104 to drive the U-shaped plate 106 to move.

[0033] The filter plate 108 is provided with a U-shaped strip 102b fixed to the housing 102. The filter plate 108 and the U-shaped strip 102b are interference fit to prevent the filter plate 108 from moving during actual use. An air outlet 102d is provided at the position of the fan 110 corresponding to the lower wall of the housing 102, so that negative pressure is generated inside the housing 102 when the fan 110 is working.

[0034] The operation process of this embodiment is as follows: When in use, the billboard is placed on the upper surface of the placement plate 103. At this time, the electric push rod 105 is extended or shortened by operating the controller to adjust the nozzle 201b to a suitable distance from the upper wall of the billboard. Then, the nozzle 201b is moved above any end of the billboard by operating the controller. At this time, the length and width of the billboard are input into the controller, and then the motor 101 and the motor 209 are controlled to work. The operation of the motor 101 drives the screw 101a to rotate, which drives the moving block 105a to move, so that the electric push rod 105 and the nozzle 201b move left and right. When the motor 209 works, it drives the screw 209a to rotate. Under the combined action of the vertical plate 104a and the moving plate 104, the U-shaped plate 106 moves back and forth, and finally the nozzle 201b moves back and forth to spray paint the billboard.

[0035] At the same time, the controller also controls the fan 110 to work continuously. Paint that is not sprayed onto the billboard passes through the gap between the placement plate 103 and the box 102 and enters the interior of the box 102. Then it passes through the filter plate 108, which uses the filter plate 108 to adsorb and filter the paint to prevent the paint from drifting and polluting the operating environment.

[0036] Example 2

[0037] Please see Figure 1 , Figure 5 and Figure 6 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but differs from the first embodiment in that: a spraying mechanism 2 is provided below the spraying frame 1. The spraying mechanism 2 includes a paint tank 202. During the spraying operation, the paint tank 202 is in a sealed state. The paint tank 202 includes a circular box and a lid. The lid and the circular box are detachably fixed. A motor 204 is fixed at the middle position of the upper wall of the paint tank 202. A rotating rod 206 is fixed on the power output shaft of the motor 204. The connection between the rotating rod 206 and the paint tank 202 is... A mechanical seal is provided. The outer peripheral wall of the rotating rod 206 is provided with multiple stirring rods 206a. The motor 204 drives the rotating rod 206 to rotate, so that the stirring rods 206a rotate to stir the paint inside the paint tank 202, so as to keep the paint in motion and prevent sedimentation. An air pipe 205 is provided above the paint tank 202. The air pipe 205 is connected to a high-pressure air pump. The high-pressure air pump has the function of automatically stopping when the upper limit of the set air pressure is reached and automatically starting when the lower limit of the air pressure is reached. This type of air pump is existing technology and will not be described in detail here.

[0038] Specifically, a connector 202b is fixedly provided on the upper wall of the paint tank 202. The interior of the connector 202b is connected to the interior of the paint tank 202. One end of the air pipe 205 is fixedly connected to the connector 202b. Connecting rods 202a are fixedly provided in a circumferential array on the upper wall of the paint tank 202. The upper end of the connecting rods 202a is fixedly connected to the box body 102.

[0039] A feed pipe 203 is fixedly installed on the upper side of the outer peripheral wall of the paint tank 202. The inside of the feed pipe 203 is connected to the inside of the paint tank 202. A pipe cap 203a is threadedly connected to the outside of the feed pipe 203. The outer peripheral wall of the pipe cap 203a is provided with anti-slip texture. By loosening the pipe cap 203a, paint can be added into the paint tank 202 through the feed pipe 203. In the painting state, the pipe cap 203a and the feed pipe 203 are in a threaded connection state. A sealing ring is provided on the inner side of the pipe cap 203a to ensure no air leakage under high pressure.

[0040] A connecting pipe 201 is fixedly installed at the lower end of the outer peripheral wall of the paint tank 202. The interior of the connecting pipe 201 is connected to the interior of the paint tank 202. To prevent the connecting pipe 201 from naturally falling and contacting the painted billboard, thus damaging the painting effect, such as... Figure 5 As shown, the upper part of the connecting pipe 201 is made of metal, while the lower part is made of flexible hose. A solenoid valve 201a is fixed on the connecting pipe 201. A nozzle 201b is fixed at the end of the connecting pipe 201 away from the paint tank 202. The nozzle 201b is fixedly connected to the bottom of the electric push rod 105. With the above configuration, when the paint tank 202 is under paint spraying pressure and the solenoid valve 201a is open, paint will pass through the connecting pipe 201 and the solenoid valve 201a into the nozzle 201b and be sprayed out. When the solenoid valve 201a is closed, no paint is sprayed out.

[0041] Furthermore, a safety valve is also fixedly installed on the upper wall of the paint tank 202;

[0042] The operation process of this embodiment is as follows: During spraying, the controller controls the motor 204 to work continuously, driving the rotating rod 206 to rotate, so that the stirring rod 206a rotates to stir the paint inside the paint tank 202. In this state, the air pump supplies high-pressure gas to the inside of the paint tank 202. When the spray frame 1 is working, the controller opens the solenoid valve 201a. The air pressure in the paint tank 202 causes the paint to pass through the connecting pipe 201 and the solenoid valve 201a into the nozzle 201b and be sprayed out, thereby realizing the spraying of the billboard.

[0043] It should be noted that motor 101, motor 209, motor 3204, solenoid valve 201a, fan 110 and electric push rod 105 are all electrically connected to the microcontroller in the controller via conductive wires. The microcontroller in the controller is electrically connected to an external power supply via conductive wires. In addition, all electrical appliances used in the spray painting equipment for billboard production are existing technologies, and their models are not limited here.
