The utility model relates to a roller screen, in particular to a self-cleaning device used on a roller screen.
Roller screen is the use of single motor single axis rotation (or motor driven by the chain to drive the shaft rotation) to promote the material along the screen surface forward movement. The particles smaller than the sieve gap are acted by the rotation force of the gravity screen and the sieve shaft, and the gap between the sieve shafts falls down, and the particles larger than the sieve holes stay on the screen surface and continue to move forward so as to achieve the purpose of sieving. But due to the screening of the material contained in the bulk, wire, thread, fabric and other debris, and the use of screen effect is not ideal, widespread pore plugging, don't feed the material rotation phenomenon; and the structure of roller screen cleaning device is compact, installation space is narrow, so the existing roll screen generally no installation of self cleaning device, which brings inconvenience to the use of the enterprise, and influence the efficiency of the equipment.
The purpose of the utility model is to design a self-cleaning device used on a roller screen with reasonable structure and good use effect.
The technical scheme of the utility model, a self cleaning device and use it on screen, including the screen roller screen frame, fixing frame, screen roller, which is characterized in that the screen roller screen frame is arranged on the lower part of the fixed frame, the fixed frame is hinged with the rotating rod, the rotating rod is fixedly connected with a clean plate. The installation position of the cleaning plate corresponding to the gap between the screen rolls, the rotating rod is provided with a special striking plate at the end part of the screen roller is provided with a cam corresponding to the cam and the striking plate shaped position limiting device is arranged under the rotating rod. Wear resistant layer is arranged in irregular striking plate in contact with the cam part.
The utility model has the advantages of more reasonable structure, no need of additional power to realize the cleaning of the roller screen, better cleaning effect of the screen of the roller screen, better effect of material feeding, and guarantee the service efficiency of the equipment.
