Problems solved by technology
[0003] In the prior art, for filter materials with a W-shaped folded structure, the folding distance is generally fixed by uniformly setting hot-melt glue lines at the folds, which requires a lot of hot-melt glue and thread bodies, not only high production costs, but also waste time The waste generated is not environmentally friendly, and the filtering effect at the hot melt glue line is also poor

Embodiment Construction
[0013] The present invention will be described in further detail below in conjunction with examples and specific implementation methods.
[0014] Such as figure 1 As shown, an air purification filter screen without glue lines, its structure includes a W-shaped folded structure filter material 1 and paper side strips 3, wherein each fold of the W-shaped folded structure filter material 1 is a folded edge 2, and the paper quality The side strips 3 pass through sequentially in the transverse direction and are fixedly connected with each folded edge 2 .
[0015] The paper side strip 3 is perpendicular to the folded edge 2 on the horizontal plane.
[0016] The paper edge strip 3 is fixedly connected with the folded edge 2 through glue.
[0017] The W-shaped pleated filter material 1 is a coarse-effect, medium-efficiency or high-efficiency filter material.
[0018] The paper edge strip 3 is 200~500g / m 2 .
[0019] The above is only the preferred embodiment of the present invent...

The invention relates to an adhesive-wire-free air purification filter screen, which structurally comprises a W-shaped folding structure filter material and paper edge strips, wherein each folding position of the W-shaped folding structure filter material is the folding edge; the paper edge sequentially passes through each folding edge in a transverse direction and is fixedly connected with each folding edge. The adhesive-wire-free air purification filter screen has the advantages that the structure is simple and effective; the folding interval of the W-shaped folding filter material is fixedthrough the paper edge strips being 200 to 500g / m<2>; the conventional hot melt adhesive wire is replaced; on the premise of ensuring the stability of the filter screen structure, the environmental-friendly performance is improved; the production cost is reduced; the filtering effect is ensured.
Description
technical field [0001] The invention relates to an air purification filter screen without glue lines. Background technique [0002] With the continuous development of the air purification field, various new types of air purification filter screens emerge in endlessly. In order to increase the contact area between the air purification filter screen and the air, the filter material is generally subjected to W-shaped discount processing to form a W-shaped folded structure filter material. . [0003] In the prior art, for filter materials with a W-shaped folded structure, the folding distance is generally fixed by uniformly setting hot-melt glue lines at the folds, which requires a lot of hot-melt glue and thread bodies, not only high production costs, but also waste time The waste generated is also not environmentally friendly, and the filtration effect at the hot melt glue line is also poor. Contents of the invention [0004] The present invention proposes an air purificat...
