The blanket 90 passes around the drying guide rollers 77, then passes through the two groups of drying pieces in the horizontal direction, and finally passes through the discharge driving roller 76 in the horizontal direction.

[0066] In order to avoid the external impurities from falling on the blanket 90, with reference to Figure 1 An outer protective cover 20 is arranged between the upper end surface of the water washing and drying box 70 and the upper end surface of the pre-dust removal box 40. The outer protective cover 20 covers the dust removal outlet 401 and the water washing and drying inlet 700. The inside of the pre-dust removal box 40 is rotatably connected with a pair of upper driving rollers 21 which are distributed in the horizontal direction at the two ends, respectively. The upper driving rollers 21 are driven by a servo motor.

[0067] The working principle of a dust cleaning and washing device for a blanket of the present application is as follows:

[0068] The blanket 90 is sequentially passed through a pair of lower driving rollers 42, a dust inlet 400, four cams 52, a dust outlet 401, two pairs of upper driving rollers 21, and then enters a water washing and drying box 70 to sequentially undergo water washing and drying. During dust cleaning, the four rotating cams 52 make the vertically arranged blanket 90 continuously and rapidly change between further tensioning and restoring the initial tensioning state, thereby achieving a shaking state. In this way, the impurities on the blanket 90 are shaken off, and at the same time, due to the suction force generated at the suction nozzle 611, the impurities are sucked into the suction pipes 66. When it is necessary to clean the suction pipes 66, the four lifting electric cylinders 63 drive the two suction seats 64 to descend, so that the lower end of the inverted L-shaped suction pipe 612 is disconnected from the connecting plug-in frame 664. Then, a pair of rotating driving electric cylinders 671 drive the translation slide plate 672 and the linkage plate 673 to descend. In this process, the linkage plate 673 moves horizontally relative to the translation slide plate 672 until all the suction pipes 66 are inclined. Next, the sealing sleeve 662 is unscrewed, and the impurities in the suction main pipe 661 slide and fall. After that, the external water supply device fills the suction main pipe 661 with water through the water inlet hose 663 to clean the suction main pipe 661.

[0069] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application. Therefore, any equivalent changes made on the basis of the structure, shape, and principle of the present application should be covered by the protection scope of the present application.
