AI Technical Summary
Existing paper folding machines do not allow for easy adjustment of the pressure roller height before creasing the filter paper, which makes it difficult to lay the filter paper and may cause the filter paper to shift after creasing, increasing the input of raw materials.
The design includes a positioning and folding assembly and a top-feeding assembly, comprising a connecting frame, cylinders, positioning blades, and a paper pusher. The automatic folding and stable movement of the filter paper are achieved through the coordinated action of the cylinders, ensuring accurate indentation.
This technology enables rapid and accurate folding of filter paper, reducing raw material waste and improving production efficiency.
