DETAILED DESCRIPTION

[0022] The present invention will be further described in detail below through the accompanying drawings and examples.

[0023] The present invention provides a needle-punched filter felt cleaning mechanism for fine particle dust removal, such as Figures 1-5 As shown, the present invention comprises a platform 1, wherein the platform 1 has a space with an upward opening, a winding box 2 and a limiting roller 3 installed on both sides of the upper edge of the platform 1, a needle felt body 15 is arranged between the winding box 2 and the limiting roller 3, an elastic pad 4 is arranged below the needle felt body 15, and a plurality of elastic rings 5 ​​are fixed to the lower end surface of the elastic pad 4, and the elastic rings 5 ​​are symmetrically arranged on both sides. A pull rod 6 is slidably connected to the bottom surface of the space, and one end of the pull rod 6 is slidably connected to the bottom surface of the space, and the other end of the pull rod 6 is provided with a protrusion 61, and the protrusion 61 is arc-shaped. The elastic ring 5 is pulled downward by the pull rod 6 until the elastic ring 5 is disengaged from the protrusion 61. After disengaging, the elastic ring 5 rebounds, driving the elastic pad 4 upward toward the needle felt body 15, and the elastic pad 4 replaces the knocking rod to clean the needle felt. Compared with the knocking rod, the elastic pad 4 has a larger contact area with the needle felt during cleaning, which not only greatly reduces the probability of the needle felt being dented and deformed, but also increases the cleaning area, thereby improving the cleaning efficiency.

[0024] Reference Attachment Figure 2 、 4 A slide groove 7 is provided on the bottom surface of the space, and the pull rod 6 is slidably connected to the slide groove 7. A cylinder 8 is provided on both sides of the platform 1. The output end of the cylinder 8 passes into the slide groove 7 and is connected to the pull rod 6.
