Abstract
The present invention relates to an apparatus for manufacturing artificial leather, the apparatus including an embossing molding device capable of efficiently forming an embossed pattern on the surface of artificial leather through vacuum adsorption molding and a method of manufacturing artificial leather using the apparatus.
Claims17
An embossing molding device, comprising:
- a roller body that is formed in a cylindrical shape and is rotated by power transmitted from a motor;
- an embossing roller formed in a tubular shape so as to be coupled to an outer circumferential surface of the roller body and provided with vacuum holes for embossing molding and a predetermined pattern for embossing on a surface thereof;
- a vacuum generator that is connected to the vacuum holes through the roller body and is responsible for generating vacuum to form, through adsorption molding, an embossed pattern on a surface of artificial leather being introduced and conveyed;
- and
- a water cooler that is installed inside the roller body and is responsible for cooling the embossing roller to a predetermined temperature,
- wherein the roller body comprises:
- a main roller for injecting air outside through a plurality of injection holes provided in an outer circumferential surface of the main roller when air is fed from an air feeder;
- a tube-shaped rubber cover that is fitted onto the outer circumferential surface of the main roller and is expanded outward by pressure due to air injected through the plurality of injection holes;
- and a vacuum bar assembly that is provided with a plurality of vacuum bars bonded radially to an outer circumferential surface of the rubber cover about a central axis of the main roller and is provided with, on an outer circumferential surface of the vacuum bar assembly, a plurality of suction holes in communication with the vacuum holes, and
- wherein, upon expansion of the rubber cover, the vacuum bar assembly expands to press and fix an inner circumferential surface of the embossing roller.
