It works as follows:

First, when assembling the main body of the advertising panel 3, the tempered film 32 and the LED display 33 are stacked up and down and installed on the middle end of the aluminum frame 31 to realize the rapid assembly of the main body of the advertising panel 3, and then complete The assembled advertising panel main body 3 is rotatably installed on the front side of the casing 1, and is rotatably connected with the telescopic rods 2 provided on the left and right sides inside the casing 1, so that the subsequent advertising panel main body 3 can realize convenient opening and closing activities. Finally, through The wiring board 34 that is integrally connected to the front side of the LED display screen 33 is connected to the subsequent electrical components inside the casing 1, so that the LED display screen 33 can display advertisements under the control of the external control terminal, and cooperate The insulating properties of the aluminum frame 31 and the anti-cracking properties of the tempered film 32 can prevent rust and prevent the panel from breaking;

And in order to avoid the use of the advertising machine outdoors, more dust is attached to the outside of the main body 3 of the advertising panel, resulting in a decrease in the display clarity of the main body 3 of the advertising panel. The operation of the cleaning device 4 drives the driving wheel 421 clockwise through the rolling wiping assembly 42 provided inside the driving housing 41, so that the driving structure 4a provided inside the rolling wiping assembly 42 drives the driving wheel 421 clockwise, that is, through the operation of the driving structure 4a. The provided drive motor 4a2 makes the drive motor 4a2 realize the synchronous up and down on the right side and sets the meshing transmission between the first gear 4a3 and the second gear 4a4, that is, the second gear 4a4 can rotate clockwise with the first gear 4a3. Connected to the connecting shaft 4a5 at the middle part of the second gear 4a4, it can synchronously drive the driving wheel 421 connected on the right side to rotate, so that the driving wheel 421 cooperates with the cleaning belt 422 connected by the outer phase transmission, and the cleaning belt 422 front side is connected to the driven wheel Driven by 423, thus, driving wheel 421, cleaning belt 422 and driven wheel 423 can realize the rolling transmission of longitudinal clockwise track, and the bristle layer 4221 integral body that is located at cleaning belt 422 outsides can roll clockwise with the bristle layer 4221 Next, the dust attached to the upper end surface of the tempered film 32 is wiped and cleaned, and then the bristle layer 4221 can realize the self-rolling cleaning cooperation on the outside of the advertising panel main body 3, which greatly improves the overall wiping and cleaning efficiency of the advertising panel main body 3;

And in order to ensure the comprehensive cleaning of the dust attached to the outside of the advertising panel main body 3, it is necessary to run the mobile assembly 45 connected to the rear side of the housing 41, that is, to make the servo motor 454 realize the output on the left side by running the servo motor 454 set inside the mobile assembly 45. Driven by the circumference of the end-connected screw 452, with the rotation of the screw 452, the moving block 453, which is threadedly connected to the outer surface of the left side of the screw 452, can move laterally along the inside of the protective shell 451. The connected housing 41 can move synchronously therewith, and drive the self-rolling rolling wiping assembly 42 to reciprocate and laterally move left and right, so that the bristle layer 4221 provided inside the rolling wiping assembly 42 can fully contact with the upper end surface of the tempered film 32, And the attached dust is fully wiped and cleaned, so as to achieve the comprehensive wiping and cleaning of the attached dust, and when the housing 41 reciprocates laterally along the upper end surface of the tempered film 32 with the moving assembly 45, in order to ensure that the housing 41 reciprocates laterally. Smooth and stable, by setting the guide shell 44 on the front side of the housing 41, that is, the connecting plate 441 and the bottom frame 443 inside the guide shell 44 are respectively provided with the first guide groove 442 and the second guide groove 444. The housing 41 as a whole realizes smooth left and right lateral movement, thereby improving the fluency of left and right reciprocating horizontal wiping and cleaning effects, and reducing the occurrence of stuck phenomenon;

In the process of wiping and cleaning the bristle layer 4221, dust is more likely to adhere to the outer surface of the bristle layer 4221, resulting in a reduction in the wiping and cleaning effect of the bristle layer 4221 after a period of time. Therefore, by installing a scraping assembly 43 outside the front end of the housing 41, During the rolling and wiping cleaning process of the bristle layer 4221, the brush bar 435 provided inside the scraping assembly 43 can scrape off and clean the dust attached to the bristle layer 4221. 432 and small spring piece 433, to carry out elastic support activities, so that the whole horizontal plate 434 can vibrate slightly, so that the brush bar 435 is intermittently contacted with the outer side of the bristle layer 4221, and the attached dust is scraped off and scattered, thereby reaching the bristle layer The outer side of 4221 is scraped and cleaned synchronously to improve the overall service life of the bristle layer 4221 and reduce the replacement efficiency. In order to avoid the scattered dust from adhering to the outer side of the main body 3 of the advertising panel again, the fan connected to the outer side of the connecting pipe 438 can be operated to make the fan Adsorption effect: Scrape off the dust from the outside, suck it from the dust suction holes 437 equidistantly set at the upper and lower ends of the horizontal plate 434, and introduce it into the suction shell 436 on the front side of the horizontal plate 434, and finally along the connecting pipe 438 is exported to the outside, thereby achieving the auxiliary export process of scraping off the floating dust and reducing the advantages of floating dust adhesion.

The utility model provides a multi-functional outdoor advertising machine panel. By setting a reciprocating cleaning device 4 and cooperating with the operation of the rolling wiping assembly 42 inside the housing 41, self-rolling cleaning activities can be performed to greatly improve the advertising panel body 3. The cleaning effect of the outer side, and the guide housing 44 and the moving assembly 45 respectively provided on the front and rear sides of the housing 41, can carry out the left and right reciprocating lateral movement of the housing 41 as a whole, so that the rolling wiper assembly 42 provided inside the housing 41, Move left and right along the upper end surface of the main body of the advertising panel 3 to improve the comprehensiveness of dust wiping and cleaning, and a scraping assembly 43 is provided on the left side of the front end of the housing 41, and a large spring piece 432 and a small spring are set inside the scraping assembly 43. The sheet 433 cooperates with the brush bar 435 to scrape and clean the outer side of the bristle layer 4221 to improve the service life of the bristle layer 4221, and is scraped off and scattered under the adsorption of the suction shell 436, the suction hole 437 and the connecting pipe 438 Dust is exported, thereby achieving the advantages of improving the dust wiping and cleaning effect on the outer surface of the advertising panel and maintaining the service life of the wiping place.
