AI Technical Summary

Technical Problem

Existing metal filter screen straightening devices have high rigidity when straightening thicker filters, making it difficult to use the overall pressing and expansion method, and the straightening process is complex. The local flattening method is not suitable.

Method used

The design combines a guide module and a flattening module. It uses guide rails, sliding frames, double-headed lead screws and servo motors to drive rotating rollers. The filter screen is straightened through guide limiting and local to overall extrusion. The distribution rollers and extrusion belt are evenly stressed, which can adapt to filter screens of different thicknesses.

Benefits of technology

It achieves localized to overall correction of the filter screen, ensuring the correction effect. It is suitable for filter screens of different thicknesses, with uniform force distribution and a simple and efficient correction process.

Abstract

The utility model relates to the technical field of metal filter screen shape correction, in particular to a shape correction device for metal filter screen production, which comprises a bottom plate, a top plate is fixedly connected above the bottom plate, a fixing frame is fixedly connected above the top plate, and an electric push rod is fixedly connected on the upper surface of the fixing frame. The upper surface of the bottom plate is fixedly connected with a guide module, the guide module comprises a guide rail, a first sliding frame, a second sliding frame and a double-end lead screw, the guide rail is fixedly connected to the upper surface of the bottom plate, and the first sliding frame is connected to the interior of the guide rail in a sliding mode. The metal filter screen can be guided and limited when entering the position between the two flattening modules, the phenomenon that the correction effect is affected by deviation of the filter screen during entering is avoided, correction of the filter screen from local to whole can be achieved, the correction effect of the filter screen is guaranteed, in addition, a sharing roller makes contact with the inner side surface of an extrusion belt, the counter-acting force borne by the extrusion belt is shared, and the correction effect is improved. And the stress on the filter screen is more uniform.
