Analysis of the reasons for the use of Die Cutting Machine paper broken
The first possibility is that there is no strict in accordance with the instructions to operate, because the specific product situation is different, there are some differences in processing methods, it is recommended that the operator must be rigorous training before they can. Die-cut strip, this is the second possibility. Strip sticks to the sides of the die-cutting knife, mainly for the die after cutting the paper from the die cutter up. But if the tape is flattened or the height is lower than the tool or stick too little or die cut out, which will cause the paper sticking to the phenomenon of die-cutting knife, it will lead to broken paper, so be sure Timely change the adjustment strip. The third reason is that the die-cutting pressure is too large, so that the steel plate will be pressed on the deeper knife marks, knife marks hook paper incision, causing paper break, broken is not surprising, and encountered such a problem Need to adjust the paper pressure in a timely manner to make it appropriate and uniform. The fourth reason is that indentation, long use or poor quality causes indentation mold surface glue, encounter high pressure will stick to the paper, then we can properly flutter some talc or directly replace Indentation mold. There is a reason, the fifth is the die cutting machine teeth teeth in the course of the use of paper thickness changes too large, it is easy to cause the loss of elasticity of the paper, this paper will produce too much pressure on the paper, So that the paper is broken. Encountered such a problem, we also need to timely adjust the paper, get a uniform paper tension.
The way of Die Cutting Machine in the way of die - cutting
1. Installation and readiness
Die Cutting Machine used in different die-cutting methods, installation and readiness of the time change is also great. If sorted by time, the entity punching the shortest, followed by the plate punching, followed by the physical pressure cut, and finally the paper pressure cut.
2. working speed
In general, the rotary table installation and debugging, then the work speed is extremely fast. But the general novice are willing to use the kind of slower drum-type Die Cutting Machine, and the use of this die-cutting method to go through a stripping paper separation process, which is commonly known as the Die Cutting Machine.
With the development of society and the improvement of people's living standards, consumers in the purchase of goods, in addition to the inherent quality of goods, the packaging of goods also put forward higher requirements, which of which Including the design of packaging and packaging of goods, but also the quality of packaging after processing requirements. Die-cutting indentation is an important production process after finishing, suitable for all kinds of printed surface finishing processing, die-cutting quality of the product directly affect the image of the whole product, so only to master the traditional die-cutting indentation technology and The new die-cutting technology research and development, in order to effectively enhance the competitiveness of printing enterprises. Die-cutting indentation technology is based on the model indentation and die-pressing two kinds of processing technology, collectively, the principle is in the mold within the mold, by applying the pressure of the size of the printing carrier paper force parts of the compression deformation or Is broken apart. Die cutting indentation equipment (referred to as Die Cutting Machine) is the main machine is die-cutting plate and cutting mechanism. The sheet is processed between the two is in the pressure under the effect of finishing the finishing of finishing technology. Die-cutting indentation plate has different types and the corresponding cutting mechanism, so that Die Cutting Machine is divided into flat pressure flat, round pressure flat and round pressure round three basic types. And flat pressure Die Cutting Machine and because of the version of the plate and the direction of the different positions of different, can be divided into vertical and horizontal two. Flat die cutting machine This Die Cutting Machine version of the plate and the thickness of the cutting mechanism are flat, when the platform and the platen of the plane in the vertical position for the vertical flat Die Cutting Machine. Die cutting machine at work, the pressure plate by the pressure to the plate and the plate pressure. Press the plate movement trajectory can be divided into two categories: one is the pressure plate around the fixed hinge swing, so at the beginning of the moment of molding, platen work surface and the template between a certain angle, so that the die cutting cut earlier into the lower part of the cardboard , Which is likely to cause the lower part of the die-cutting plate pressure and the upper part of the phenomenon is not completely cut through. In addition, the die force of the die force will cause the lateral displacement of the cardboard. Another kind of pressure plate movement mechanism Die Cutting Machine in the work, the pressure plate in the connecting rod driven by the first cylindrical roller as the fulcrum, in the base of the flat rails swing, until the work surface of the platen by the tilt to the molded version Parallel to the position, and then parallel to the way to pressure to die-cutting version. Vertical flat pressure flat press has the advantages of simple structure, easy maintenance, easy to grasp its operation and replacement of die-cutting indentation plate, etc., but the labor intensity is bigger, the production efficiency is low, the number of times per minute work is 20 times ~ 30 times, Commonly used in small batch production. Horizontal flattened Die Cutting Machine plate and platen surface are horizontal position, the following pressure plate by the mechanism to press up to the plate and die-cutting indentation. Due to the small travel of the horizontal die-cutting press plate, it is difficult to manually insert or remove the cardboard. Therefore, it is usually accompanied by an automatic paper feeding system. The overall structure is similar to that of a sheet-fed offset press. Input system, die-cutting part, cardboard output part and electrical control, mechanical transmission and other components, and some also with automatic cleaning device. Horizontal flat pressure Die Cutting Machine work safe and reliable, and its automation and production efficiency are relatively high, is flat pressure die cutting machine in the advanced models.
