The quality of the die cutting machine is affected by the precision of the die cutting, resulting in this situation, if you can not find the reason from the mechanical aspect, can you change your mind, consider the impact of the environment, the impact of the operator and the plate making problem three aspects.
First, environmental impact. Mainly cardboard deformation or stretch, resulting in "overprinting" is not allowed, thus affecting the die-cutting accuracy. Try to ensure that die-cutting indentation and printing are carried out in the same working environment or ensure the unity of the working environment. Die-cutting pretreatment should be carried out on the glazed and coated sheets to minimize the influence of paper deformation on the die-cutting accuracy. Appropriate paper should be selected to reduce the impact of material defects on die cutting accuracy.
Second, the impact of the operator. This includes the entire production process from plate making to printing die cutting, requiring the operator to operate strictly in accordance with the process flow, improve production management requirements, and conduct professional skills training for the operator when necessary.
Three, plate making problems. If there are problems in the process of design and plate making, advanced plate making methods should be selected to improve the accuracy of die cutting plate; Or correction template, mainly printing and die cutting position to be correct. Manual plate making is prone to deviation, which may make the position of printing inconsistent with the position of die cutting, and the stencil needs to be re-made if necessary.
Which kinds of automatic high-speed die-cutting machine can be divided into?
First, circular die cutting machine
Circular die cutting machine as a die cutting machine, often used in large quantities of die cutting. The cylinder is equivalent to the embossing cylinder, which is used for pressure during die cutting, and the other is the drum knife die. There are two categories of knife die, wood knife die and metal knife die, wood knife die mainly die cutting relatively thick corrugated cardboard, the other is the use of chemical corrosion or electronic engraving method of metal drum knife die, generally used for self-adhesive labels and trademarks die cutting.
Two, circular pressing die cutting machine
Circular die cutting machine in the domestic application is less, the domestic basically no manufacturers.
Three, flat pressing die cutting machine
Flat die cutting machine is one of the most common automatic high-speed die cutting machine, domestic and foreign manufacturers are also more. Domestic such as Xinchuan machinery and other relatively large die-cutting machine manufacturers have the production of this die-cutting machine. Flat die cutting machine can be used in a wide range of applications, can be applied to a variety of die cutting materials, and can not only manual paper semi-automatic die cutting, but also all machine operation, automatic die cutting. It can not only die cut corrugated cardboard, self-adhesive, cardboard, but also die cut rubber, sheet metal and other materials.
Vertical flattening die cutting machine, is what we call the tiger mouth, because its work is similar to the bite of the mouth, easy to hurt people, so the name tiger mouth. The working characteristics of vertical flat die cutting machine are illustrated very vividly. Vertical die cutting machine can also be divided into semi-automatic and automatic two types. At present, the domestic production is basically semi-automatic type, and the paper feeding and receiving are manually completed. Because the safety degree in the production process is closely related to the proficiency of the operator, the novice is more prone to safety accidents, so some developed countries prohibit the use of this kind of machine.
