Because of the circular die cutting machine work continuous rotation of the drum, and therefore its production efficiency is the highest of all types of die cutting machine. But the die-cutting plate should be bent into a curved surface, plate making is more troublesome, the cost is also higher, there is a certain degree of technical difficulty. Therefore, the round die cutting machine is often used in mass production.
Circular die-cutting machine die-cutting method
Circular die-cutting machine die-cutting method, generally divided into two kinds of cutting method and soft cutting method.
Hard cutting method refers to the hard contact between the knife and the surface of the pressure roller during the die-cutting, so the die-cutting knife is easier to wear.
Soft cutting method is in the pressure roller surface covered with a layer of engineering plastics, die cutting, the knife can have a certain amount of cutting, which can protect the knife, but also to ensure that completely cut off, but need to regularly replace the plastic layer.
Circular pressure circle die cutting machine work
Circular pressure circle die cutting machine plate platform and pressure cutting mechanism of the two parts of the work are cylindrical, when working, the paper feed roller will be sent to the cardboard between the molding plate roller and pressure roller, by the two will be clamped to the roller for die-cutting, die-cutting plate roller rotates for a week, it is a cycle of work.
Die-cutting equipment workflow
Currently, most of the advanced die-cutting equipment to printing, die-cutting combination of fully automatic direction, will die-cutting machinery and printing machinery this production line consists of four main parts, namely, the feeding part of the printing part, the die-cutting part, feeding part, etc..
Feeding part: intermittent cardboard input to the printing part, according to different forms of material, size, type, etc., convenient and accurate adjustment.
Printing section: it can be composed of 4-color-8-color printing units, which can adopt different methods such as gravure, offset, flexo and so on. This part has more advanced printing functions and is equipped with its own automatic drying system.
Die-cutting part: it can be flat-pressing die-cutting machine or round-pressing die-cutting machine, and all of them are equipped with waste-cleaning device, which can automatically eliminate the edge waste produced after die-cutting.
Conveyor part: the die-cutting process is completed after the collection of products and send out, so as to ensure that the feeding part of the printing part and die-cutting part of the smooth realization of high-speed continuous operation.
