Indentation mechanism of partition-plate-free air filter, paper folding machine and use method

Abstract

The invention provides an indentation mechanism of a partition-free air filter, a paper folding machine and a using method. The indentation mechanism comprises a driving hobbing cutter and a driven hobbing cutter matched with the driving hobbing cutter, the driving hobbing cutter and the driven hobbing cutter each comprise a roller, hard cutter heads are evenly distributed on the side wall of each roller in the circumferential direction at intervals, soft cutter heads are arranged between every two adjacent hard cutter heads, the hard cutter heads of the driving hobbing cutter are correspondingly matched with the soft cutter heads of the driven hobbing cutter, the soft cutter heads of the driving hobbing cutter are correspondingly matched with the hard cutter heads of the driven hobbing cutter, the paper feeding edge of each hard cutter head is an arc face, and the paper discharging edge of each hard cutter head is a right-angle edge. According to the indentation mechanism of the partition-free air filter, the paper folding machine and the using method, damage and collapse during indentation of the filter paper are avoided, indentation is easily formed, a finished filter element is uniform in flow resistance, and the percent of pass is high.

Description

technical field [0001] The invention relates to the technical field of folding paper machines without partitions, in particular to an indentation mechanism of an air filter without partitions, a paper folding machine and a use method. Background technique [0002] High-efficiency origami machines without partitions are mainly used to produce high-efficiency air filters without partitions. The hobs of existing high-efficiency origami machines are mostly metal-to-metal butt joints, and creases form folds. The pressure adjustment of the screw is not easy to control, and it is easy to use The filter material is damaged, or the forming angle is not enough, and the smoothness and uniformity of the corrugated appearance are not enough. [0003] CN201745220U discloses an indentation device for an air filter without a partition, comprising an indentation shaft, a rubber strip and an indentation knife, the rubber strip and the indentation knife are evenly arranged on the indentation s...

AI Technical Summary

Problems solved by technology

Figure 1 and Figure 3 The two schemes both have high damage rate of filter paper indentation After the filter paper still has a lot of problems such as collapse

In addition, the creasing knives are prone to improper installation. If the radial height of one of the creasing knives is too high, it will cause periodic high verticality and unevenness of the origami when forming the origami.
