Maintenance of the die-cutting machine: First of all, the operator should pay attention to dust and clean. In actual production, a large amount of waste paper edge and paper hair will be produced when die-cutting the carton. If you pay attention, you will enter the chain transmission part, the die-cutting part moving platform and some rotating motion parts, and may block the photoelectric detection head, etc. , causing a malfunction. Therefore, it is necessary to put the cleaning work of the die-cutting machine in the first place, and then ensure that the machine runs without trouble.
Second, the oil change of the die-cutting machine. The main action of the die-cutting machine is that the main motor drives the sliding rods and pulleys, and then drives the four pairs of toggles to move. It can reach 6000 sheets per hour in high-speed work. It is very troublesome without good lubrication and cooling.
1. Round die cutting machine
One roller is equivalent to the impression cylinder, and pressure is applied during die cutting; the other is a roller die. There are two types of drum cutters, wood and metal. The former is mainly die-cut thick corrugated cardboard. The latter has metal roller cutters processed by chemical etching or electronic engraving. It is mainly used for die-cutting of labels and trademarks. There is also a metal roller die cutter mainly used for medium and high-grade long-line products, in the form of press-cut or shear.
2, round flat die cutting machine
The application of the circular flat die cutting machine in the market is very small, there is no professional manufacturer in China, and will not be described here.
3, flat die cutting machine
The flat die cutting machine is the most widely used type at present, and it is also the model with the largest number of manufacturers at home and abroad. The flat die-cutting machine can be used for various types of die-cutting, which can be used for manual paper-feeding semi-automatic die-cutting, as well as automatic high-speed linkage die-cutting; it can mold corrugated cardboard, paperboard, self-adhesive, and Die-cut rubber, sponge, metal sheet, etc.
The vertical flat die cutting machine, commonly known as the tiger mouth, refers to the bite movement of the mouth when it is working. It is named because it is unsafe and easy to hurt people. In any case, the working characteristics of the vertical flat die cutting machine are illustrated in an image. The vertical flat die cutting machine is mainly divided into two parts: the fuselage and the press frame, and the die-cut plate is mounted on the fuselage. There are two types according to its mode of operation: single pendulum and double pendulum. The so-called single pendulum type means that when the die-cutting, the pressure frame swings, the body does not move (that is, the plate does not move), the plate is first contacted with the lower part of the pressure frame, and the upper part is contacted, the upper part is left at the end of the die cutting, and the lower part is left. In this way, the force time is different, and the force is uneven, so the use is less and less, and slowly eliminated. The double pendulum type means that both the fuselage and the press frame have an action when the die is cut. Before the contact, the plate lithography and the plate are parallel, and the contact form is parallel movement, so the pressure is large and uniform. Most of the vertical flat die cutting machines produced are of this type. The vertical flat die cutting machine can be divided into semi-automatic and fully automatic according to the degree of automation. At present, the vertical flat die-cutting machine (tiger mouth) produced in China is mainly semi-automatic, the die-cutting is done by the machine, and the paper feeding and delivery are done manually.
