Die cutting processing technology is mainly used to mold and indentation various cardboards, and can also module and indentation processing of leather, plastic, and other materials. The characteristics of die cutting are simple operation, low cost, good quality, fast -effectiveness. Choosing a suitable die-cutting machine can not only help companies better occupy the market and lay a good foundation for the further development of the enterprise.
Die cutting machinery introduction
The working principle of the die-cutting machine is to use steel knives, hardware molds, and steel wires (or templates carved by steel plates), and apply a certain pressure through the pressing version to cut the prints or cardboard into a certain shape. If the entire print is pressed into a single graphic product as a die cutting; if the steel wire is used to press the marks on the print or leave the bending grooves as the indentation; Heating to a certain temperature, the patterns or fonts with three-dimensional effect on the surface of the print are called hot cashmere; if one substrate is used to repeat it on another substrate, exclude For discharge; the above can be collectively referred to as die cutting technology.
Classification of die cutting machine
The die-cutting machine is widely used in packed processing molding, with a wide variety and powerful functions. What types of die cutting machines are divided into? The die cutting machine is mainly divided into three types: round-round, round-falt, and flat-flat.
Round-round die cutting
The working parts of the layout and the pressing mechanism of the round-round die cutting machine are round cylindrical. When working, the paper roller sends the cardboard to the mold voltage roller and the pressure drum. Living in the drum to die, the mold-cut roller rotates for a week, which is a working cycle.
The die cutting method of the round-round mold is generally divided into two types: cutting method and the soft cutting method. The hard cut method refers to the hard contact between the knife and the pressure roller during the die cutting, so the die cutting knife is easier to wear. The soft-cut method is to cover a layer of engineering plastic on the surface of the pressure roller. When cutting, the cutting knife can have a certain amount of entry, so that it can protect the cutting knife and ensure that the cutting is completely cut, but the plastic layer needs to be replaced regularly.
Because the roller rotates continuously when the round-round mold is working, its production efficiency is the highest among various die cutting machines. However, the mold-cutting version should be bent into a curved surface, the version of the version is more troublesome, the cost is relatively high, and there are some difficulties in technology. Therefore, the round-round die cutting machine is often used for mass production.
At present, advanced die cutting equipment is mostly developed in the automatic direction of the combination of printing and die cutting. The production lines such as die cutting machinery and printing machinery consist of four main parts, that is, the printing part of the feed part, the die cutting part, the delivery part of the part, and the part of the section. Wait.
The inlet part is intermittently input to the printing part, which can be adjusted according to the convenience and accuracy of different materials forms, sizes, and types. The printing part can be composed of 4-8-color printing units, and different methods such as concave, glue, and flexible version can be used. This part has a more advanced printing function and is equipped with its own automatic drying system. The die cutting part can be a flat-flat mold cutter or a round-round mold cutter, and all have a waste device, which can automatically eliminate the corner waste generated after the die cutting. The transportation part is to collect and send the product after the die cutting process is completed, so as to ensure that the printing part of the feeding part and the die cutting part can smoothly achieve high-speed continuous operations.
With the improvement of the technical level in recent years, the price of the round-round die cutting equipment has significantly reduced, and currently has a wide range of user groups in China.
Round-Flat die cutting
The round-flat die cutting is mainly composed of a flat-type section and a rotating cylindrical pressure roller. During the working itinerary, the platform moves forward to die cutting and indentation on the cardboard; when the itinerary is replied, the platform returns back, and the working surface of the pressure roller does not contact the mold. This type of mold machine can be divided into several types such as stopping, one-time rotation, and two-round rotation according to the pressure roller in a working cycle. It can be a work trip.
Flat-Flat die cutting
The layout and crimping mechanism of this mold cutter are flat-shaped. When the plane of the section and the pressure plate is in the vertical position, the vertical flat-pressing mold is cut. When the die cutting machine is working, the pressure plate is pressed to the version by transmission to the version. Different motion trajectories of pressing plates can be divided into two categories: one is the pressure plate around the fixed hinge, so at the moment of the start of the mold, there is a certain angle between the working surface of the pressure plate and the template so that the die cutting version is cut into the lower part of the cardboard earlier This is easy to cause the lower part of the mold version of the lower part and the upper part is not completely transparent. In addition, the division of die cutting pressure can cause the horizontal displacement of the cardboard. During the work of another type of motion-mounted motion mechanism, the pressure plate is driven by the link, first, use the cylindrical roller as the fulcrum, and swing on the flat guide rail of the seat. When in a parallel position, then press it in parallel to the die cutting.
The vertical flat-pressure flat mold compressor has the advantages of simple structure, convenient maintenance, easy to master operation, and replacement of die cutting marks, but the labor intensity is large and the production efficiency is low. Commonly used for small batch production.
The layout and pressure plate working surface of the horizontal flat-pressure flat die cutting machine is horizontal positions, and the pressure plate below is driven upward by the mechanism to the layout of the layout.
Because the stroke of the horizontal die cutting machine is small, it is more difficult to put it in or remove the cardboard manually, so it usually has an automatic paper-in-in-law system. The overall structure is similar to the single paper rubber printer. The input system, die cutting part, cardboard output part, and electrical control, mechanical transmission, and other parts, also have an automatic cleaning device.
The workmanship of the horizontal flat pressure flat mold is safe and reliable, and its degree of automation and production efficiency is relatively high. It is an advanced model in the flat pressure and flat die cutting machine.
Roll paper die cutting
The rolling paper die cutting machine has a round-round and round-flat type. The flat-pressure flat roll paper die cutting machine is a machine that is used for die cutting marks by roll paper inlet paper. Wired outside and online. The external processing of the line is to print the rolling cardboard with a printing machine, and then put the roll paper that is returned to the rolling machine to the mold-cutting machine input paper frame for die cutting marks. The characteristics of the external processing method are that the printing machine is not connected with the die cutting leach, and it is not restricted to each other. Printing machine adjustment printing can be coordinated with multiple die cutting machines with printing machines, or the booting time of the die cutting marks machine can be increased.
The in-line processing method is to connect the die cutting machine to the printing machine to form a connected carrier, which is produced with printing and die cutting splitter in the rolled cardboard. This method can reduce the operator, but the general printing machine is generally higher, and the speed of the die cutting leach machine is low. The speed of the two cannot be matched. It can only reduce the speed of the printing machine. Production efficiency is affected.
Die cutting creasing
Die cutting creasing is a comprehensive collective referral of two processing technologies, two processing techniques of cutting according to the model indentation and molding. The principle is that within the shaped mold, the printing carrier paper is accompanied by compression deformation or broken separation by applying pressure. The main parts of the die cutting indentation device (referred to as the die cutting machine) are the die cutting platform and the pressing mechanism. The processed board is between the two, and the die cutting technical processing is completed under pressure. There are different types and corresponding pressure-cutting mechanisms in the die cutting indentation version, which makes the die cutting machine divided into three basic types: flat-flat, round-flat, and round-round type. Because the flat-pressing and flat mold cutter are different because of the different positions of the platform and the pressure version, they can be divided into two types: vertical and horizontal type.
Preparation before purchasing die cutting machine
Consider the needs of enterprises.
Recent demand and long-term development planning and as much as possible. Before planning the procurement of die cutting equipment, there must be a summary and calculation of orders in the factory that needs to cut machining in the factory. This is the basis for determining the number of die cutting equipment and models that are equipped with procurement. There is a clear understanding of the types of materials to be processed and produced. Based on this, the type and specification surface of the procurement die cutting device is used to use a fully automatic flat-voltage flat mold cutter, or a semi-automatic flat-pressure flat mold cutter, and so on.
Consider operability
The complexity of the operation determines the cost of equipment and the feasibility of automation technology. Even the teachers who have been engaged in die cutting for many years are difficult to achieve complex assembly. If it is not necessary, it is difficult to make investment and return proportional.
Performance overall evaluation.
Purchase die cutting machines should pay attention to the paper collection mechanism, main transmission system, positioning mechanism, intermittent institution, pressure agency, pressure mechanism, and waste-clearing institutions focusing on the main transmission system, positioning mechanism, intermittent institution pressure mechanism, and cleaning waste. Understanding and comparing the structural characteristics and performance of key institutions is essential for the final determination of models. If you need to buy medium and low-grade molding machines, you should obviously purchase domestic machines if you need to buy high-end die cutting machines, you should comprehensively make production tasks, the accuracy requirements of the product with the accuracy of the product, the stability and reliability of the cost-effective machine, and the after-sales service points. Analyze and select the optimal procurement plan.
The procurement die cutting machine also pays attention to its performance indicators, mainly suitable for processing materials, size or thickness of the die-cutting material, the highest die cutting speed, die cutting accuracy, function (such as whether it is cleared, secondary waste cleansing, and the secondary waste cleansing. , Whether there is scalding, holographic scalding, etc.), the highest degree of automation of the highest die cutting pressure. Focus on the speed of the die cutting speed and the die cutting accuracy of the die cutting pressure. But the key to buying is suitable for the needs of enterprises and products.
Comprehensive considerations should be made according to the enterprise’s own scale, economic tolerance, product category, product accuracy requirements, and production volume, and choosing the appropriate equipment. Do not be too blind. The procurement die cutting machine also pays attention to its performance indicators, mainly based on the materials processed by the enterprise, the size or thickness of the die cutting material, to pay attention to the highest die cutting speed, die cutting accuracy, and function of the die cutting machine (if it is clear whether it is clear Waste, secondary cleaning), the highest die cutting pressure, and the degree of automation. The focus is on the die cutting speed, die cutting accuracy, and die cutting pressure. But we can’t blindly pursue the most advanced equipment blindly. Although the higher the speed and accuracy, the more function, the higher the module pressure, the better The current development situation will cause waste of resources. Always remember that the die cutting machine that conforms to the company’s own production scale and product conditions is the most suitable.
