Introduction and working principle of die cutting machine
1. Introduction of die cutting machine
Die cutting machine, also known as die punching machine, die cutting reasing machine, is mainly used for die cutting (full break, half break), indentation of some non metallic materials, self adhesive, EVA, double sided tape, mobile phone rubber pad, etc. And bronzing operation, lamination, automatic waste discharge, the die cutting machine uses steel knives, metal molds, steel wires (or stencils carved from steel plates), and applies a certain pressure through the embossing plate to roll the printed products or cardboard into certain shape. It is an important equipment for post press packaging processing.
2. Working principle of die cutting machine
The working principle of the die-cutting machine is to use a steel knife, a metal mold, a steel wire (or a template carved from a steel plate), and apply a certain pressure through the embossing plate to roll the printed product or cardboard into a certain shape. If the entire printed product is pressed into a single graphic product, it is called die cutting; if a steel wire is used to press marks on the printed product or leave a bent groove mark, it is called an indentation; Heating to a certain temperature, hot stamping a pattern or font with a three dimensional effect on the surface of the printed product is called bronzing; if one substrate is used on another substrate, it is called lamination; excluding the rest except the genuine product is called bronzing. In order to discharge waste; the above can be collectively referred to as die cutting technology.
3. Die cutting machine classification
Die cutting machines are mainly divided into three types: cylinder die-cutting machine, rotary die-cutting machine, and flat bed die-cutting machine according to the different stamping forms. According to the form of template placement, it can be divided into vertical and horizontal. According to the degree of automation can be divided into: manual, semi automatic and automatic three. In terms of function, in addition to die cutting, there is also a hot stamping function, which is called a hot stamping die cutting machine. Some have an automatic stripping function, which is called a stripping die cutting machine.
Cylinder die cutting machine is characterized by line contact, low die cutting pressure, and high production efficiency. It can be connected with offset printing machines, flexo printing machines, gravure printing machines and other printing equipment for in line die cutting, so it has a wide range of applications.
4.Die cutting machine purchase
(1) Pay attention to the procurement of various parts of the die cutting machine, and evaluate the paper feeding mechanism, delivery mechanism, main drive system, positioning mechanism, intermittent mechanism, pressure mechanism and waste removal mechanism of the die cutting machine. It is the main drive system, positioning mechanism, intermittent mechanism, die cutting mechanism and stripping mechanism. It is necessary to understand the structural characteristics and functional characteristics as much as possible. Because the quality of these components directly affects the future use effect, it must be strictly checked when purchasing. This is critical.
(2) The performance of the die cutting machine cannot be ignored. Purchasing a die cutting machine should also pay attention to its performance indicators, mainly according to the material processed by the carton enterprise and the size or thickness of the die cutting object to pay attention to the highest die cutting of the die cutting machine. Speed, die cutting accuracy, functions (such as with or without waste removal, secondary waste removal, with or without hot stamping, holographic hot stamping, etc.), the highest die cutting pressure, and the level of automation. Focus on die cutting speed, die cutting accuracy and die cutting pressure. But we can’t blindly pursue the most advanced equipment is the most suitable, although the higher the speed and precision, the more functions, the higher the die cutting pressure, the better the die cutting machine with the higher the degree of automation, but if it is not suitable for enterprises The current development situation will result in a waste of resources. Always remember that the die cutting machine that matches the company’s own production scale and product conditions is the most suitable.
