Die cutting and creasing line processing

Cutting knife and the indentation line installed in accordance with the first line of each piece of box-type knife the length of the cutting knife or indentation lines cut, bent into the appropriate length and shape of its special equipment main blade cutting machine , blade machine (machetes machine), blade punching machine (bridge cutter machine), machine blade cutting angle.

China packaging industry to use more manual control process equipment Voltage Shaver Cutter line workers, are commonly used by foreign CAD system software tool for molding processing. To ensure the accuracy of die-making, CAD software can automatically calculate the cutting knife and the length and the bridge indentation line size, and send to the computer-controlled machine tool for grooving, cut, bend and cut. As a result of hydraulic machetes, liquid crystal display, hydraulic transmission, and cursor positioning tool can effectively ensure the accuracy of shape.

Base mold (backing) technology Using a die cutter complete with the bottom mold, make packaging cartons (boxes) of the line more clearly, beautiful, and folded without wrinkles and cracks, box (box) shape more accurate.

Domestic production base model with manual multi-mode fiber abroad is to use more insulation board base model, because fiber is very hard need special slot machine, fiber base model is only applicable to very long-living parts of the die plate indentation, For the short-term, cost too high. The bottom line of such paste-type mold, outlet fast, full line indentation resistance, high strength and India. With the development of our country believed that the traditional end of module will be replaced by the advanced indentation system.

Materials development Cutting tool directly determines the quality of the end of time and cutting up the quality, speed and frequency. Creasing the quality of the wire determines the degree of indentation of the fine, and the speed of automatic folder gluer significant effect. After a series of high-quality die-cutting knife is made of the processing technology. Po to take the company, such as Austria, as the market leader in die-cutting knife, cutting knife continued commitment to technology development, and development of different objects with different hardness cutting different shapes of the cutting blade knife. Recently, the company for many tobacco, food boxes, medicine boxes to the cutting of the long version, clean, high quality requirements, but also timely introduction of a super supreme knife, its blade is characterized by inward convergence, can sustained to maintain excellent The cut through the performance, to minimize the fluff, from silk and other phenomena, a new “king of cutting knife.”

The development of cutting equipment Die die-cutting machine according to the form can be divided into rotary, round flatten, flatten three types. At present, the cutting and processing various types of equipment, localization has taken shape, and in constant development to improve.

Die Cutting Machine will be high speed, high precision, fully automatic, multi-direction. Foreign advanced automatic platen die cutting machines were powered by a programmable controller and touch screen human-machine dialogue control, mechanical drive system with pneumatic clutch and torque most of the security controller, the production speed of up to 12,000 / hour, cutting accuracy 0.1mm. Automatic registering device can effectively improve the cutting accuracy. In addition to centralized control by computer, without stopping the machine to the paper and receive automatic paper positioning technology, advanced automatic platen die cutting machine also has automatic stripping, automatic separation of box-chip functions.

Domestic die-cutting machine products are mainly concentrated in the middle and low level of domestic enterprises to use the high-grade die-cutting machine is still mostly imported products. Strict limits on the device behind the development of domestic cutting process, so is the development of high-speed die-cutting machine finishing equipment, a major breakthrough innovation.

Pre-printed web development needs of rotary printing die cutting machine production line transport production to assembly line form of production, not only can improve the printing, die cutting, creasing precision positioning register, you can also control the roll tension changes, thus ensuring the correct pattern register. Web-fed rotary printing and die cutting production line with high efficiency, speed, high precision die cutting, total pressure of a small, smooth motion, It is the packaging carton

Mentioned that the digital printing, people first think of its advantages: speed, short cycle, low cost, good effect … … tasted the “sweetness” of enterprises and businesses which is full of praise.

The industry generally believes that this new printing method will give the traditional printing methods to bring a technological innovation.

The production process of digital printing simple, eliminating the traditional printing process to the film, system, Fence and other cumbersome processes, the general sampling time is not more than one working day for up to three working days, while the traditional proofing cycle normally in a week about. Therefore, greatly reduced the cost of digital printing.

Digital printing from the process perspective, but also through the production process conditions, with large cargo consistent steaming, baking, washing and other processes, color fastness, and other indicators can be compliance, consistent with the large goods production. At the same time, can be done right flowers is very accurate, customer acceptance of digital printing, after playing the demo, large cargo is often used rotary screen, flat-screen production, which is the difference between objective reality.

But in the digital printing proofing, the pre-taking into account of this difference, an increase in the future production of large goods may arise such as stacked color effects, minimize the sample with the large gap between the goods.

Of course, different ways of printing, digital printing to simulate the effect of it is not the same, customers playing demo, you need to specify the future production of large goods is rotary or flat screen.

Digital printing production to achieve a small volume, fast response to customer demand, production-grade, personalized printing products have an advantage.

The current development is mainly focused on improving the printing speed and reduce the printing cost of production (mainly dyes printing material cost is higher).

Dyeing and finishing technology as a new development in digital printing will gradually become an important high-end textile printing processing methods.

Digital printing is not a flower pattern Wai size chromatography restrictions on flowers accurate, rich layers of printing effect is good, can be used for high-end textile printing.

Are mainly two kinds of reactive dyes printing printing printing and coating processes, Zhejiang Textile Institute Center for digital printing mainly on cotton, polyester, hemp, silk fabrics (knitted and woven) on the printing.

III Printing Machine development ? Flat screen printing machine Although the rotary screen printing show absolute advantage, and there has been greatly improved fineness, but the flat screen printing still will not be eliminated. In fact, the flat screen printing technology is re-valued, due to printing small quantities of the trend is increasing, from an economic point of view, in this case, use the flat screen printing is beneficial. (See Table 4)

Table 4 flat screen and rotary screen printing of the relative cost of printing a continuous quantity (m) the relative costs

Flat screen rotary screen 200 100 125 500 90 110 1000 70 85 3000 40 40 Digital system networks and shorten the time for networks to introduce automation technology to facilitate more into a flat screen printing printing technology can not be ignored. There are two new models, printing belt can be heated to 50 , and the workers get the same platen nuanced and fine printing results. A multifunctional KOMBIPRINT printing machine, and rotary screen flat screen combination of the characteristics of the robot is equipped with printing devices for network and scratch to achieve a complete automation.

Rotary screen printing machine Printing machine manufacturer’s European allies have made their interest focused on rotary screen printing machine, especially dedicated to the research and development of an effective system to reduce the printing process of the fabric and Colorants Waste. University of Leicester’s DeMontFort

Britain from the eight printing plants collected printing flaw data analysis report, the most common flaw is not allowed to flower and set lines are not allowed. In the old equipment, and calibration of the flowers by visual observation and manual adjustment to be completed to waste a lot of fabric. Over the past 10 years, there have been many improvements in this area, for example, can be calibrated with a laser beam alignment screen, you can also used to correct the position of each screen. In order to eliminate Gear Space or drive shaft torque error caused by the deformation, in the printing machine Zimmer with the AC servo motor, and Stork printing machines are used to directly drive sieve Classification With or without stage ring motors. Stork provided to improve the accuracy of the other improvements is the use of franking machines installed in each head Sensor Probe fixed to the conduction band of metal, with precise control pulses to drive a single screen, to ensure that the conduction band and the screen simultaneously, this technology is STORK patent, referred to BPMS. For example, the new RD-DD-type and Dong Jia Susi type rotary screen printing machine, printing machine in each head a separate transmission system are installed, each equipped with a ring motors, rotary screen can be connected directly with motor rotor ring without the need for error prone transmission, relying on the pulse motor Generator With electrodes measuring device and can be very precise control of speed and correct angle position rotary screen, with BPMS positioning measurement system is the transmission belt from the head, both through Electronic Control the precise linkage. Such a separate transmission of rotary screen printing machine, between two adjacent network accuracy of the spend up to 0.06mm.

DeMontfort University study shows that, if installed, the advanced system, beginning in the printing of fabric used to spend about 90% can be saved. The ultimate goal of the study is printing machine equipped with an intelligent video monitoring and flaw identification system, now has EVS camera system can be applied to detect and report defeats printed fabrics.

Improve the efficiency of low-volume product key is printed screen replacement time. Improved ways to increase mechanization and the installation of an electronic control system. Most printers use open-grid and the open style Bearing Easy to change blade and rotary screen. Buser claims, the application of appropriate equipment, a 7-color printing machine for network time only 15 minutes. If the net 25 times a day for the aircraft’s efficiency up to 70%. Now have a washing-line network systems, for example, Stork’s Print @ Change printing machine of each head is equipped with retractable curtain gate, can be across the machine, the screen under the extension, to prevent changing / washing net dripped onto the fabric when the paste. If a confidential 16-color printing of two consecutive 8-chromatography of the patterns produced, the system can ensure that the minimum net result for the time delay caused. According to Reggiani and Ichinose introduced through line cleaning, the cleaning of Circular 15 chromatography, about 10 minutes to complete.

Different slurry system has been studied scraping, scraper and scrape the roller rotary shear behavior of a series of theoretical results as reflected in the report. The results show that compared with the scraper, magnetic roller scraper no particular advantage. Zimmer has developed hydraulic crack style to the pulp slurry scraper hydraulic device can be adopted by the slit-type net drag increases to the slurry paste, on the velvet fabric has good penetration effect, but there are also slit the outer edge of and wear problems between Screen. The device is suitable for Carpet Printing or foam printing.

Addition to the traditional way of printing the standard, the Japanese company’s eastern extension (Ichinose) introduced the tilting rotary screen printing method. Paste from the top down input, always keep the equal to the supply of fresh paste quantitative reduction of paste in the turret because impurities cause the blade scars and uneven printing result for the pulp segment marks, products, printing quality improved.

Equipment manufacturers also try to limit “waste slurry” and re-use the remaining amount of colorant way to reduce the waste of printing paste. Stork company unique paste recovery system, with a special Pump By a plastic ball will remain in the pulp slurry pipe hydraulic back colorant. In order to control the minimum waste of paste to predict the length of a printed color back to the required amount of paste is very valuable. Impact of peace on rotary screen printing paste used actual production capacity of equipment parameters, the results show that, for the determination of the printing speed, fabric structure, screen mesh, and scrape pulp device Foot Inch, the predicted amount of paste at 15% error can be controlled within.

Domestic printing machine development and manufacturing have made some progress, Huangshi, Hubei, Shanghai, Zhejiang Xinchang manufacturers such as cooperation with foreign countries and the introduction of technology, both development and production of advanced flat screen or rotary screen Printing Equipment . But compared with foreign equipment, the functionality, performance and stability, there are still some gaps.

Digital Printing System

Digital printing can not only save Plate Processes, reduce costs, but also to save printing digital pattern, which makes the printing methods become more attractive, research in this area in the ascendant. Currently, the most promising fabric Ink jet Printing paper used Print
