Title:
DIE CUTTING MACHINE FOR PREVENTING NESTING DEFECT CAUSED BY ELECTROSTATIC ADSORPTION OF MATERIALS TO MACHINE
Document Type and Number:
WIPO Patent Application WO/2021/147291
Kind Code:
A1
Abstract:
Disclosed is a die cutting machine for preventing a nesting defect caused by electrostatic adsorption of materials to a machine, characterized in that: a feeding end of the die cutting machine is provided with an antistatic rope for discharging static electricity from a material strip, and the antistatic rope is located beside a position where the material strip passes and is in contact with the material strip; the surface of a lower template of the die cutting machine is provided with a plurality of parallel ribs, and a gap is reserved between the top ends of adjacent ribs so as to reduce the friction between the material strip and the lower template; a discharging end of the die cutting machine is provided with a material lifting roller mounted above a pulling-down shaft,the material lifting roller is located, in a horizontal direction, on the outer side of the contact part of an pulling-up shaft and the pulling-down shaft and is parallel to the width direction of the material strip, the material strip extending from the pulling-down shaft passes over the material lifting roller, and the material strip attached to the pulling-down shaft is lifted. The die cutting machine of the present invention reduces the negative impact of the electrostatic adsorption force on the material correction movement during the positioning process of a nesting hole, and can complete high-precision machining.
