Background technology
Referred to as " be die cut " with the cutting that cuts out mould and carry out of closed geometric shape, this cut out mould can for circular, oval or
Polygon and any type of irregularly shaped.Process conducted in post-press finishing as carried out being die cut using piercer,
Corner cut and index cross cutting fall within the field.Cross cutting is realized towards a cross cutting cushion block or towards die, partly
It is shear history.The packaging material being made up of paper, cardboard, hardboard or corrugated paper are mainly die cut with page specification.In cross cutting
During also can additionally in useful part apply streak line or arch flower.The process of the complexity causes page to be individually cut
It is indispensable.Because final product is related to the packaging for having high requirement in terms of the enforcement of technology and figure(For example use
Packaging in cosmetics, cigarette, medicine, food etc.), therefore not only special requirement, Er Qiewei are proposed to packaging material itself
Optimal result requires the die-cutting machine of the cross cutting instrument with minimal tolerance and extremely accurate and reliable operation.Platform die-cutting machine
These requirements can most preferably be met.Here, page that is having printed and stacking on supporting plate is supplied to the die-cutting machine.In the machine
In device, page to be die cut is accurately oriented in an orienting device, is accepted and accurately in mould by a gripper car
In cutting apparatus fixed supported leave from office and can be vertically movable by toggle link or radial gear appear on the stage between position.
Carry out being die cut, imprint in the known page for being made up of paper, cardboard and analog, stripping and if necessary
Useful part separation and the page that places are die cut and are well known that with marking press, make page motion by the machine by means of gripper car
