US 2014/0196422 A1 · WAVY COMPOSITE CORE AND MANUFACTURING METHOD THEREOF

Abstract

A wavy composite core is provided. The wavy composite core includes wavy filtering layers and flat filtering layers alternately stacked and rolled to form a barrel shape for filtering suspended pollutants. Each wavy filtering layer has a plurality of peak portions extending axially, a plurality of axial sealing adhesive layers formed on the peak portions by coating sealing adhesive on the peak portions so as to bond the wavy filtering layer to the flat filtering layers adjacent to the wavy filtering layer, and two end sealing adhesive layers formed on opposite sides by coating sealing adhesive on the wavy filtering layer to bond the wavy filtering layer to the adjacent flat filtering layers.

A wavy composite core comprising a plurality of wavy filtering layers and a plurality of flat filtering layers alternately stacked and rolled to form a barrel for filtering suspended pollutants, wherein each wavy filtering layer has a plurality of peak portions extending axially, a plurality of axial sealing adhesive layers formed on the peak portions by coating sealing adhesive on the peak portions so as to bond the wavy filtering layer to the flat filtering layers adjacent to the wavy filtering layer, and two end sealing adhesive layers formed on opposite ends of the wavy filtering layer by coating sealing adhesive on the wavy filtering layer to bond the wavy filtering layer to the adjacent flat filtering layers.

A manufacturing method for a wavy composite core, comprising the following steps:

(a) forming a wavy filtering layer and a flat filtering layer for filtering suspended pollutants, wherein raw material is pressed by shaping rollers to form the wavy filtering layer having peak portions on which axial sealing adhesive layers are formed by coating sealing adhesive on the peak portions, and the raw material is tensioned by a driving roller and a press roller to form the flat filtering layer at the same time;
(b) forming a first end sealing adhesive layer and bonding the wavy filtering layer to the flat filtering layer, wherein the first end sealing adhesive layer is formed on the wavy filtering layer by coating sealing adhesive at one end on one side of the wavy filtering layer by a first gluing gun, and the flat filtering layer is pressed and bonded to the wavy filtering layer by means of the axial sealing adhesive layers and the first end sealing adhesive layer;
(c) forming a second end sealing adhesive layer, wherein the second end sealing adhesive layer is formed on the wavy filtering layer by coating sealing adhesive at the other end on the other side of the wavy filtering layer by a second gluing gun;
and
(d) obtaining the wavy composite core material, wherein the bonded wavy filtering layer and flat filtering layer are rolled to form the wavy composite core having a barrel shape.
