Description

Technical Field

[0001] This utility model relates to the field of advertising light box spray painting technology, specifically to an advertising light box spray painting device. Background Technology

[0002] Advertising light boxes use materials such as vacuum forming, acrylic, and printed fabric as base materials. They are hollow, box-type advertising carriers widely used in public places such as commercial streets, shopping malls, train stations, and subway stations, as well as for shop signs and billboards. They are also suitable for indoor and outdoor advertising, such as in high-speed rail stations, airports, streets, 4S stores, restaurants, hospitals, and communities. The patent publication number in China is CN 220111377. U discloses an advertising lightbox painting device, including a paint spraying box. A guide rod is slidably connected inside the paint spraying box. A connecting pipe is fixedly welded to one end of the guide rod. A nozzle is fixedly installed on one side of the connecting pipe, and a spray pipe is fixedly welded to the other side. This advertising lightbox painting device allows the connecting pipe to move laterally by moving the spray pipe laterally, facilitating adjustment of the distance between the nozzle and the advertising lightbox and reducing paint consumption. The design of the fixing block and screws can fix the position of the spray pipe, preventing it from moving automatically during painting operations and affecting normal painting. By starting the motor to drive the fan blades to rotate, harmful gases inside the paint spraying box can be extracted into the filter shell and filtered through the activated carbon layer, bamboo charcoal layer, and filter screen, reducing the harm of harmful gases to the surrounding environment. Moving the filter shell upwards causes the magnetic ring to be removed, facilitating the upward removal of the activated carbon layer, bamboo charcoal layer, and filter screen for cleaning and replacement.

[0003] The above-mentioned technical solution, an advertising lightbox spraying device for advertising production, in use, drives the connecting pipe to move laterally by moving the spray pipe laterally, which facilitates the adjustment of the distance between the spray head and the advertising lightbox. Then, the spray pipe is fixed in position by the cooperation of the fixing block and screws. However, in this process, a screwdriver is required to drive the screw. If a matching screwdriver is not available, the adjustment work cannot be performed. Therefore, the convenience is low, and the screw may strip due to frequent installation and disassembly.

[0004] Therefore, a spray painting device for advertising light boxes is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide an advertising lightbox spray painting device in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0020] like Figure 1-4As shown, an advertising lightbox painting device includes a paint spraying box 1, a door 2 hinged to the paint spraying box 1, a support column 3 at the bottom of the paint spraying box 1, an auxiliary mechanism 4 for pressing and fixing the advertising lightbox and being rotatable on the paint spraying box 1, an adjustment mechanism 5 for adjusting the position distance on one side of the paint spraying box 1, a painting mechanism 6 for painting the advertising lightbox on one side of the paint spraying box 1, a filter assembly 7 on the paint spraying box 1, and an auxiliary mechanism 4 including a cylinder 404 mounted on the top of the paint spraying box 1. The telescopic end of the cylinder 404 is slidably mounted on the paint spraying box 1, a rectangular plate 405 is mounted on the telescopic end of the cylinder 404, a rotating plate 406 is rotatably mounted on the rectangular plate 405, and a soft rubber mat is mounted on the surface of the rotating plate 406. A rotating seat 401 is rotatably mounted on the spray box 1. A fixing post 402 is mounted on the surface of the rotating seat 401 and rotatably mounted on the spray box 1. A motor 403 is mounted at the bottom of the fixing post 402 and is mounted on the surface of the spray box 1. The adjusting mechanism 5 includes a fixing frame 501, which is mounted on the surface of the spray box 1. A double-acting screw 502 is rotatably mounted inside the fixing frame 501. Two adjusting rods 503 are threaded onto the outer wall of the double-acting screw 502 and slidably mounted on the fixing frame 501. One end of the double-acting screw 502 extends outside the fixing frame 501, and a torsion handle 507 is mounted on the surface of the extended end of the double-acting screw 502. The surfaces of the two adjusting rods 503 are... Each of the four connecting posts 506 is equipped with a mounting rod 504. A connecting plate 505 is mounted on the surface of each mounting rod 504. Two connecting posts 506 are mounted on the surface of each connecting plate 505. The painting mechanism 6 includes a paint tank 601, which is mounted on the surface of the paint tank 1. A paint pump 602 is mounted on the top of the paint tank 601. A suction pipe 604 is provided on the paint pump 602 and is located inside the paint tank 601. A branch pipe 603 is provided on the paint pump 602. Two sprayers 605 are mounted on the surfaces of the four connecting posts 506, and the branch pipe 603 is mounted on the two sprayers 605. The branch pipe 603 is slidably mounted on the paint tank 1. In this embodiment, it is explained that the filter assembly 7 consists of a fixed shell, The system is composed of a fiberglass filter, dust filter, activated carbon plate, support plate, air duct, and exhaust fan. The fiberglass filter typically serves as the primary filtration layer; its dense fiber structure effectively blocks large dust particles and paint mist. The dust filter further filters fine particles in the air; its mesh design can block medium-sized dust and paint mist particles. Installed after the fiberglass filter, it ensures that only finer particles enter the next filtration layer. The activated carbon plate has a strong adsorption capacity, capable of adsorbing harmful gases and odors in the air, including volatile organic compounds (VOCs) that may be released from paint. Installed last, the spraying distance of the spraying mechanism 6 is adjusted according to the width specifications of the advertising lightbox via the adjusting mechanism 5.The advertising light box is then placed on the auxiliary mechanism 4, which pre-presses and fixes it. The painting mechanism 6 then sprays paint onto the light box. The auxiliary mechanism 4 then rotates the light box, allowing it to be sprayed with paint from multiple directions. The filter assembly 7 filters harmful gases generated during painting, thus achieving the pressing and fixing of the light box and enabling its rotation for multi-directional painting. The spraying distance is adjustable, making it easy to operate and highly practical. The starting cylinder 404 moves the rectangular plate 405 downwards, adjusting its height. As the rectangular plate 405 moves downwards, the rotating plate 406 and the soft rubber pad move downwards as well, making close contact with the light box and pressing it onto the rotating base 401. The motor 403 is fixed and started, driving the fixed column 402 and the rotating seat 401 to rotate. The advertising light box and the rotating plate 406 rotate accordingly. Turning the torsion handle 507 drives the bidirectional lead screw 502 to rotate, causing the two adjusting rods 503 to move closer or further apart, thus adjusting the distance between the two adjusting rods 503. When the two adjusting rods 503 move closer or further apart, the two mounting rods 504, two connecting plates 505, and four connecting columns 506 move according to their trajectory. When the four connecting columns 506 move closer or further apart in pairs, the two spray guns 605 move accordingly, and the branch pipe 603 slides on the paint tank 1. The paint pump 602 is started, drawing paint from the paint tank 601 and transporting it to the spray guns 605, which are then sprayed onto the advertising light box.

[0021] In summary, the filter assembly 7 consists of a fixed housing, a fiberglass filter, a dust filter, an activated carbon plate, a support plate, an air duct, and an exhaust fan. The fiberglass filter typically serves as the primary filtration layer; its dense fiber structure effectively blocks large particles of dust and paint mist. The dust filter further filters fine particles in the air; its mesh design can block medium-sized dust and paint mist particles. Installed after the fiberglass filter, it ensures that only finer particles enter the next filtration layer. The activated carbon plate has extremely strong adsorption capacity, capable of adsorbing harmful gases and odors in the air, including those from paint. Potentially released volatile organic compounds (VOCs) are installed at the end. During use, the spraying distance of the spraying mechanism 6 to the advertising light box is adjusted by the adjusting mechanism 5 according to the width specifications of the advertising light box. Then, the advertising light box is placed on the auxiliary mechanism 4, which pre-presses and fixes the advertising light box. The spraying mechanism 6 sprays paint on the advertising light box, and the auxiliary mechanism 4 drives the advertising light box to rotate, so that the advertising light box receives paint spraying from multiple directions. The filter component 7 can filter the harmful gases generated by spraying paint, thereby achieving the pressing and fixing of the advertising light box and driving its rotation. It allows for multi-directional painting and adjustable spraying distance for the advertising lightbox. It is easy to operate and highly practical. Starting cylinder 404 moves rectangular plate 405 downwards, thus adjusting its height. As rectangular plate 405 moves downwards, rotating plate 406 and soft rubber pad move downwards accordingly, making close contact with the advertising lightbox and pressing it onto rotating base 401 for fixation. Starting motor 403 rotates fixed column 402 and rotating base 401, causing the advertising lightbox and rotating plate 406 to rotate. Turning torsion handle 507 rotates bidirectional lead screw 502. The two adjusting rods 503 move closer to or further apart, thereby adjusting the distance between them. When the two adjusting rods 503 move closer to or further apart, the two mounting rods 504, the two connecting plates 505, and the four connecting columns 506 move accordingly according to their movement trajectories. When the four connecting columns 506 move closer to or further apart in pairs, the two spray guns 605 move accordingly, and the branch pipe 603 slides on the paint box 1, activating the paint pump 602 to draw paint from the paint box 601 and transport it to the spray guns 605, which are then sprayed onto the advertising light box.
