The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.
It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" or "in communication with" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "upper", "lower", "vertical", "horizontal", "left", "right" and the like as used herein are for illustrative purposes only and do not denote a unique embodiment.
Referring to fig. 2, a die cutting plate according to an embodiment includes a base 10, an indentation blade 20, and a stress relief device 30.
The base 10 is used for fixing the indentation cutter 20 and the stress relief device 30, and when the die cutting plate works, the die cutting plate is fixed on a pressing plate of a die cutting machine through the back surface of the base 10.
Specifically, the base 10 is a flat plate, and has a fixing portion for fixing the indentation cutter 20, the material of the base 10 is selected from any one of a fiber board, a polymer plastic board and a metal board, and preferably, an artificial fiber board is used as a cheap and light material, which can be used as the material of the base 10 of the present invention.
Further, the fixing portion is a slit, and the size of the slit is matched with that of the creasing blade 20 and used for fixing the creasing blade 20.
And an indentation knife 20 fixedly arranged on the base 10 for making an indentation line on the packaging material.
Specifically, the indentation knife 20 is in a convex sheet shape, and is fixedly disposed on the base 10 through the fixing portion, and has good pressure stability, and may not be deformed under the working pressure of the die cutting machine, thereby preventing the indentation knife 20 from being deformed or displaced during the die cutting operation. The creasing blade 20 is made of a metal material, and preferably, the creasing blade 20 is made of an elongated stainless steel material. Referring to fig. 5, in operation, the paper packaging material is disposed between the die cutting plate and the pressure plate, and the corrugated paper core of the packaging material is pressed, folded and deformed by the pressure of the creasing blade 20, and thus loses stiffness and pressure-bearing capacity to form a creasing line a.
Further, the indentation blade 20 is designed in a "convex" shape, and its convex portion is engaged with the slit of the base 10 as a blade back as a fixed portion.
In some embodiments, referring to fig. 8, the indentation knife 20 is provided with a rounded chamfer 201, and by providing the rounded chamfer 201, the acting force of the indentation knife 20 during the indentation operation can be dispersed, and the surface layer material of the pitted paper packaging material can be prevented from being broken during the indentation operation.
