manufacture example

[0018] An actual manufacturing example is given below to illustrate:

[0019] First prepare a PU foamed elastic pad with a thickness of about 5 mm. Cut the elastic cushion body with a knife die, which is provided with a plurality of circular cutters arranged in a matrix, and each cutter is provided with an ejector device. When the elastic cushion body is cut, the knife The cutting knife of the mold will take out the part of the elastic pad falling in the cutting knife, so that the elastic pad is divided into a 5mm thick elastic sheet with a circular hole and a 5mm thick elastic sheet falling in each cutting knife. Two parts of round elastic pellets.

[0020] Afterwards, hot-melt glue on one side of the elastic sheet, and attach a fabric layer A with a thickness of 1mm, and at the same time, move the knife die to another fabric layer B with a thickness of 1mm that has been hot-melt glued, and then press The ejecting device pushes out the circular elastic granular materials in...

Abstract

The invention relates to a production method of a breathable, graininess and expanded laminating material, and the steps of the method are that: an elastic gasket body is prepared and a cutting die is used for trimming. The cutting die is provided with a plurality of cutters which prearrange trimming shapes and the interior of each cutter is provided with a liftout attachment. When in cutting, the cutter can be dropped on a part one of the elastic gasket body in the cutter and then the part one is dragged out so as to cause the elastic gasket body to be divided into an elastic sheet provided with holes with prearranged shapes and a part two of an elastic granular material in each cutter, and then one side of the elastic sheet is laminated with a fabric layer, meanwhile, the cutting die ismoved to another fabric layer to push out the elastic granular material so as to ensure that the elastic granular material can be bonded on the fabric layer, and the other side of the elastic sheet is laminated with a fabric layer while one side of the elastic granular material is laminated with a fabric layer, thus forming the laminating material which is provided with the elastic sheet with holes and the elastic granular material provided with a clearance.

Description

technical field [0001] The present invention relates to air-permeable laminated materials, in particular to a method for manufacturing air-permeable granular foamed laminated materials. Background technique [0002] The main structure of the existing laminated breathable material is composed of an elastic layer sandwiched between two cloth layers. At present, the elastic layer can be roughly divided into two types. One is made by punching an elastic pad. The method is to prefabricate a perforated elastic pad first, and then attach cloth to both sides of the pad. This approach will waste the hole material after punching. The other is formed by dispersing granular or columnar elastic materials. Its manufacturing method must be manufactured by injection, and cannot be fast and mass-produced by laminating. Contents of the invention [0003] The object of the present invention is to provide a kind of manufacturing method of air permeable granular foam pasting material, to ov...
