[0024] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 One embodiment provided by this utility model:

[0026] A projection screen rewinding and cleaning mechanism is disclosed in this application. The drive motor 3, telescopic rod 6, adhesive tape 12, and mounting frame 14 used in this application are all commercially available products. Their principles and connection methods are existing technologies well known to those skilled in the art, and therefore will not be described in detail here. The mechanism includes a mounting frame 1, a side plate 2 mounted on the right side surface of the mounting frame 1, a drive motor 3 mounted on the back of the side plate 2, a rewinding roller 4 mounted through the output end of the drive motor 3 inside the side plate 2, a guide assembly mounted inside the mounting frame 1, a cleaning assembly mounted on the outer surface of the guide assembly, and a fixing assembly mounted on the outer surface of the mounting frame 1.

[0027] The guide assembly includes a mounting plate 5 and a telescopic rod 6. The telescopic rod 6 is installed inside the mounting frame 1, and the mounting plate 5 is installed on the right side surface of the telescopic rod 6. The telescopic rod 6 is model HLF01A.

[0028] The cleaning assembly includes a mounting block 7, which is installed on the back of the mounting plate 5. A top plate 9 is mounted on the top surface of the mounting block 7, and a scraping block 10 is mounted on the front surface of the top plate 9. In use, the projection screen is rolled up on the outer surface of the take-up roller 4. The rotation of the drive motor 3 drives the projection screen on the surface of the take-up roller 4 to perform take-up and untake-up operations. When roll-up is required, the drive motor 3 drives the take-up roller 4 to wind and roll up the projection screen. The projection screen then sits between the mounting plate 5 and the limiting roller 8. The limiting roller 8 limits the position of the projection screen, resulting in a good overall limiting effect and preventing significant displacement of the projection screen during the roll-up process.

[0029] The front surface of the mounting block 7 is equipped with limiting rollers 8, and both the mounting block 7 and the limiting rollers 8 are provided in two sets. The mounting frame 1 has an adapter groove 11 inside, which is mutually adapted to the winding roller 4. The scraping block 10 will abut against the right side surface of the projection screen, so that when the projection screen rises, it will abut against the left side of the scraping block 10. The scraping block 10 can clean the right side surface of the projection screen, resulting in a better overall operation effect. Therefore, this setting, through the cooperation of the guiding component and the cleaning component, can not only limit the projection screen during the winding process, but also clean its surface during the winding process, solving the problem of the previous problem of the screen accumulating after cleaning.

[0030] The fixing components include adhesive tape 12 and mounting frame 14, both of which are mounted on the right side surface of mounting bracket 1. Adhesive cloth 13 is mounted on one side of the surface of mounting bracket 1, and the adhesive cloth 13 is compatible with the adhesive tape 12. A slot 15 is provided inside the mounting frame 14, and a limiting plate 16 is installed inside the slot 14. Two sets of limiting plates 16 are provided, with the left side of the limiting plate 16 adhering to the right side surface of the curtain. After the projection screen is wound up on the surface of the take-up roller 4, the adhesive tape 12 is stretched and then adhered to the adhesive cloth 13. The adhesive cloth 13 will then adhere to the outer surface of the wound projection screen, fixing the projection screen in place. During use, the projection screen falls downward between the mounting plate 5 and the limiting roller 8, and then the limiting plate 16 is pushed inside the slot 15. The limiting plate 16 can limit the lower end of the projection screen, preventing the lower end of the projection screen from being blown away by external wind. This results in better overall stability during use. Therefore, this setting can not only fix the wound projection screen, but also limit the projection screen in use, thus enhancing the usage effect.

[0031] Working principle: When the operator uses this device, first connect the device to an external power source to provide power support. At this time, the projection screen is rolled up on the outer surface of the take-up roller 4. The rotation of the drive motor 3 can drive the projection screen on the surface of the take-up roller 4 to perform take-up and unrolling operations. When it is necessary to roll up, the drive motor 3 drives the take-up roller 4 to wind and roll up the projection screen on its surface. Then, the projection screen will be between the mounting plate 5 and the limiting roller 8. The limiting roller 8 can limit the position of the projection screen, so the overall limiting effect is good and the position of the projection screen will not shift significantly during the rolling process. Then, the scraping block 10 will abut against the right side surface of the projection screen. When the projection screen rises, it will abut against the left side of the scraping block 10. The scraping block 10 can clean the right side surface of the projection screen.

[0032] After the projection screen is wound up on the surface of the take-up roller 4, the adhesive tape 12 is stretched and then the adhesive tape 12 and the adhesive cloth 13 are adhered to each other. Thus, the adhesive cloth 13 will adhere to the outer surface of the wound projection screen and fix the projection screen. At the same time, when the projection screen is in use, the projection screen falls downward between the mounting plate 5 and the limiting roller 8, and then the limiting plate 16 is pushed inside the slot 15. Thus, the limiting plate 16 can limit the lower end of the projection screen and prevent the lower end of the projection screen from being blown away by the outside wind. The above is the working principle of this utility model.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
