Automatic edge sticking device for filter element

Abstract

The invention discloses an automatic edge sticking device for a filter element. The automatic edge sticking device comprises a paper feeding device, a paper folding device, an edge sticking device body and a cutting device, wherein the paper feeding device conveys folded paper to the paperfolding device, the paper folding device is used for sequentially conveying the folded paper to the edge sticking device body and the cutting device, when the paper folding device is used for conveying the folded paper, the paper folding device is used for folding the current folded paper to form a pluralityof paper folding units, moreover, the edge sticking device body is used for sticking edge strips on the two sides of the current folded paper, and the cutting device is used for cutting the folded paper and the edge strips. According to the automatic edge sticking device for the filter element, the folded paper can be stably and uniformly folded, the automatic edge sticking operation can be carried out stably and uniformly, and meanwhile, the sizes of the paper folding units of each folded paper can be accurately controlled, so that the qualified rate of produced products is guaranteed, the production efficiency is improved, and the internal quality and the appearance attractiveness of the products are greatly improved.

Description

technical field [0001] The invention relates to an automatic welting device for filter cores, in particular to an automatic welting device for filter cores of air filters. Background technique [0002] At present, there are three ways of welting air filter elements: 1. Mechanical gluing, manual placement of paper cores, and manual welting; 2. Mechanical gluing, manual placement of paper cores, and mechanical welting; 3. Mechanical gluing, automatic classification Paper core, automatic welting. Among them, the first two methods need to manually place the paper core, because the manual placement of the paper core will consume more labor, the cost is high, and there is no prospect. However, the current automatic paper core separation and automatic edge welting devices (applied patents 201010117114.6, 201010617716.8 and 201220295279.7) are troublesome to adjust the machine due to unstable paper core separation and gluing, and the waste of materials is large. This technology has...

Among them, the first two methods need to manually place the paper core, because the manual placement of the paper core consumes more labor, the cost is high, and there is no prospect

However, the current automatic paper core separation and automatic edge welting devices (applied patents 201010117114.6, 201010617716.8 and 201220295279.7) are troublesome to adjust the machine due to unstable paper core separation and gluing, and the waste of materials is large. This technology has been developed It has not been popularized and applied in the industry for a few years, and what could have promoted the transformation and upgrading of the industry has not been able to make a difference now

There is also a kind of welting device (2014206019187) applied by the applicant, which will cause a certain proportion of scrapping during the production process. The reason is that the stickers are not folded evenly.
