Problems solved by technology

The self-cleaning projection cloth utilizes the stickiness of the rubber rod itself to clean the projection cloth through the friction between the projection cloth and the rubber rod when the projection cloth enters and exits the projection cloth box. The device cleans the screen through the electrostatic effect of the glue rod, but the The device can only clean the front of the screen, but does not clean the back, so the screen will still be contaminated with dust after winding, which will affect the subsequent use of the screen

Embodiment 1

[0025] see Figure 1-4 , a self-cleaning projection cloth, comprising a top plate 8, the bottom of the top plate 8 is provided with a side plate 7, the right side of the upper surface of the top plate 8 is provided with a drive motor 12, the output shaft of the drive motor 12 is fixedly connected to the first pulley 11, the second A pulley 11 is connected to the second pulley 9 through the belt 10, the second pulley 9 is fixedly connected to the right end of the main shaft 6, the two ends of the main shaft 6 are connected to the side plate 7 in rotation, the middle part of the main shaft 6 is provided with a winding roller 13, and the outside of the winding roller 13 Curtain 1 is wound, and the left end of the main shaft 6 is provided with a driving gear 5, the front and rear sides of the driving gear 5 are engaged with the driven gear 2, the driven gear 2 is fixedly connected to the left end of the rotating shaft 3, and the two ends of the rotating shaft 3 are connected to the...

Embodiment 2

[0028] Other contents of this embodiment are the same as those of Embodiment 1, except that the cleaning roller 4 is made of rubber. Due to the particularity of the surface material of some professional curtains 1, the surface of the curtain 1 cannot be cleaned directly by a brush. At this time, it is necessary to replace the cleaning roller 4 with a rubber roller, and use the electrostatic action of the rubber roller to clean the surface of the curtain 1. The dust is adsorbed on the outside of the rubber roller. After a period of use, the rubber roller can be cleaned.

[0029] In the implementation process of the present invention, the top plate 8 is fixed on the position where the curtain 1 needs to be suspended. When using the curtain 1, the drive motor 12 is started, and the output shaft of the drive motor 12 drives the first pulley 11 to rotate, and the first pulley 11 passes through the belt. 10 drives the second pulley 9 to rotate, so that the second pulley 9 drives the...

Abstract

The invention relates to the technical field of multimedia, and discloses automatic cleaning projection cloth. The cloth comprises a top plate, wherein side plates are arranged at the lower part of the top plate, and a driving motor is arranged on the upper surface of the top plate; an output shaft of the driving motor is fixedly connected with a first belt wheel; the first belt wheel is connectedwith a second belt wheel through a belt; the second belt wheel is fixedly connected with the right end of a main shaft; a winding roller is arranged in the middle of the main shaft, and a curtain iswound outside the winding roller; a driving gear is arranged at the left end of the main shaft; the front side and the rear side of the driving gear are in engaged connection with driven gears, and the driven gears are fixedly connected with the left end of a rotating shaft; cleaning rollers are arranged in the middle of the rotating shaft, and sliding rods are slidably connected to the left sideand the right side of the side plates on the back face, and fixed plates are arranged at the ends of the front faces of the sliding rods; the central parts of the fixed plates are rotatingly connectedwith a rotating rod; and the central part of the rotating rod is provided with a pressing roller. According to the automatic cleaning projection cloth, the two cleaning rollers on the front side andthe rear side are used for cleaning the two faces of the curtain at the same time, thereby guaranteeing that the curtain cannot be mingled with dust after being wound.
