Paper reel unwinding machine operation of the installation. According to the requirements of continuous printing, gravure printing machines generally use Usually web Konica Minolta, the machine model is different from the outer diameter of the mandrel uncoiler paper differ more, usually 3, 6 or 12 inches, so the order volume When the roll paper, the first lithography, consider paper mandrel diameter size, generally require larger than the inner diameter of the paper roll core mandrel 2-5mm appropriate, so mainly on account of changes in the transport process and web Core Diameter paper spindle mounted; second, it should pay attention to the maximum outer diameter roll Hengli color card printing company uncoiler can use this range if the roll diameter than the printed map will not be able to install and use. Scan during installation, check whether the deformation Zhixin, if the deformation is too large and should be repaired first, after the commencement of direction straightened paper printing market, the paper roll paper core mandrel is inserted, the distance between the two ends of the mandrel examination paper , try to roll mounted centrally. After the machine, you can compare the lateral position of the rolls, to ensure at the same lateral position. If uncoiler automatic stitching bin Hengli ink color card printing quotes, after the web machine, according to the requirements of open-book machine, and according to the butt or lap, crossed stitching position, double-sided, single-sided paste adhesive tape. In the splicing process, a combination of print, to ensure a consistent overall diameter two roll speed. If uncoiler bin manually, scroll down the web after cut, adjust the horizontal position of the paper, directly attached to the beginning of the new web. Currently, the printed circuit board (PCB) industry, through the development of Hengli color card printing for decades, has become an emerging global big business. PCB market space evidence in recent years, the rapid development of China's electronic information industry, exports grew 40% - 45%, PCB industry has lagged behind the overall growth rate of the electronic information industry, multilayer and HDI board production is more far behind market, the need to rely heavily on imports, PCB industry there is still much room for development. According to China's Ministry of Information Industry, "Information Industry Science and Technology Development 'Eleventh Five-Year Plan and the 2020 long-term planning framework", a printed circuit board (especially multi-layer, flexible, scratch just combined and green printed circuit board technology) is the 15 One of the key development areas for 15 years - over the next five electronic information industry - If you have some interest in interpretation PCB for electronic products, most people are split over some electronic products, such as radios, computers and other products. You will find these products in all kinds of circuit boards dense texture, a section of the line clearly visible form the basis of equipment operation, which is a printed circuit. Benefits printed circuit board is no need to carry out time and again in the welding Hengli color card printing, eliminating the need for a large number of complex manual wiring operation, and can achieve high precision, so that the production efficiency of the circuit board is greatly improved. Printing can be larger picture narrow plate, printed circuit also can reduce electronic circuit diagram plate, thus preparing the conditions for an integrated circuit production. Today, all computers and all electronic products, are used in the printed circuit. PCB industry opportunities and challenges in 2014, the global economic downturn continued development, the development of the plight of China's PCB industry will continue for some time. But it is worth looking forward to, with the increasingly fierce international competition, promote China's PCB enterprises to strengthen technological innovation, promote industrial technology is becoming more rational layout; at the same time, China's industrial development policy measures are constantly adjusted, PCB industry development environment will be further improved. Hengli color card printing, color card printing (certified), Hengli color cards printed by the Dongguan City, often beyond packaging products factory provided. Dongguan Chang-ping beyond packaging products plant (www.dgcyp.com) Dongguan, Guangdong, printing paper leaders, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In all walks of life beyond the printing leadership with the staff warmly welcomed the inquiry negotiations to create a better future beyond printing.
