Title:
ARC-SHAPED CUTTING METHOD FOR MULTI-LAYER MATERIAL
Document Type and Number:
WIPO Patent Application WO/2022/160668
Kind Code:
A1
Abstract:
The present invention relates to the field of disposable hygiene products, and in particular to an arc-shaped cutting method for a multi-layer material. Said method comprises the following steps: a first step, inputting the multi-layer material in a stacked manner, and using a hot pressing device to perform hot pressing on two sides of the multi-layer material, wherein the hot pressing ensures that the multiple layers of material are mutually bonded and not separated from one another; a second step, using a first suction conveying device to convey the material, and then feeding same into an arc-shaped cutting device to perform arc cutting; a third step, using a scrap suction nozzle to suction and remove scraps after arc-shaped cutting, the scrap suction nozzle being arranged below the arc-shaped cutting device, the multi-layer material after the arc-shaped cutting being transferred by a transfer wheel device, and then lengthened conveying being performed by means of collaboration of a second adsorption conveying device and the transfer wheel device. The present invention solves the technical problems that when the existing arc-shaped cutting device performs arc-shaped cutting on a multi-layer material, a material layer which is not attached to a suction bottom roller is easy to become loose or roll up, resulting in a bad cutting effect, and scraps enter a main line of the products.
