Double-layer filter paper pressing and folding equipment

Abstract

The invention discloses double-layer filter paper pressing and folding equipment, and relates to the technical field of filter paper production, the double-layer filter paper pressing and folding equipment comprises a lower seat body, an upper seat body, a driving cylinder, a lower indentation die, an upper indentation die, an ultrasonic lower die, an ultrasonic upper die, an unwinding frame, a stepping conveying wheel set, an expansion manipulator and a forming assembly; the upper seat body is fixed on the equipment rack through a driving cylinder, is opposite to the lower seat body in position, and is used for driving the upper indentation die and the ultrasonic upper die to move downwards so as to carry out indentation treatment and welding treatment on the double-layer filter paper raw material; the expansion manipulator is provided with a horizontally placed paper supporting knife and is used for outwards supporting the paper fold along the indentation through rotation to form the paper fold; the forming assembly is used for conveying the expanded folded paper and baking and shaping the folded paper to form a filter paper finished product; the technical effects that the accuracy and automation of filter material expansion can be improved, the operation process is simplified, the working efficiency is improved, filter paper finished products are easy and convenient to tighten and shape, the application range is expanded, and the filter paper forming effect is improved can be achieved.
