      In early 2016, rated speed 600 m/min (mechanical speed 650 m/min) of the two TB201620 high speed precision coating production line, in ningbo xinda printing machinery co., LTD developed independently, recently passed test in user factory acceptance, at and above the user and the design requirements and expectations will be domestic drum material coating equipment in a state of non-stop change volume and stable coating work speed, highest from only 200-300 m/min to 600 m/min. Innovation has the milestone significance of the device, not only represents the highest level in domestic, also marks the wave xinda leading the domestic high speed precision coating equipment design and manufacturing, is close to the international advanced level.

 

      Ningbo xinda printing machinery co., LTD was founded in 2001, is located in the beautiful port city of ningbo, is a professional production of high-grade gravure printing equipment, precision coating and composite of state-level high-tech enterprises, have a good and high quality r&d team.Fruitful research achievements in recent years, including "high-speed electronic spindle drive gravure press" 2007 ministry of science and technology awarded the "national key new product", 2014 "electronic shaft driving high speed reel material printing machine key technology development and industrialization" won the second prize of science and technology progress prize of zhejiang province. Independent research and development of "FHD multifunctional composite coating machine" in 2013 "national first (set)" products.
Bear the national ministry of science and technology during the 12th five-year five-year science and technology support project "high precision coating equipment key technology research and industrialization", this is with strong technology research and development and precision manufacturing capabilities, the company in five (three well-known international companies and domestic two) companies competing for the winning at a stroke, in a bid to take the two high speed precision coating production line of research and development manufacturing work.

 

       TB201620 high speed precision coating production line, the use of a number of innovative core advanced technology and a new design concept, the main performance index has reached the international advanced level completely. The whole machine adopts Siemens servo control systems, high-end machine high speed up to 650 m/min, successfully solved the problem of the low noise high speed precision transmission; And biggest roll diameter is 1800 mm, winding level degree within the 5 mm, maximum width 1620 mm, with a top speed of non-stop automatic rewinding function change to overcome the problems of high speed and reliable by volume.

       Coating device of precision mechanical parts and drive system is the key technology of high precision coating technology. The production line adopts the slit type hot melt adhesive squeeze and anilox roll sealing scraper precision coating unit, the two groups in the same material for the first of two coated surface. Die head slit type hot melt adhesive coating is a kind of green environmental protection coating technology, production speed, high efficiency, low cost, the main solid model after heating melt glue, by hydraulic filling quantity will glue the coating die directly spray on the base material. Closed blade coating mainly adopts anilox roller coating roll for glue coating, its production speed is fast and uniform coating, the coating weight accurately.

      600 m/min high-speed automatic volume change is one of the difficult points of this production line, in addition to the required loading rotary rack with high stability, safe and reliable also calls for high speed cutting, high success rate, convenient loading volume. For the production line adopts the independent external double location gear disc type feeding mechanism, innovative USES on both ends of a material with a material volume driven servo motor coordination, namely "coaxial double motor drive technology, prevent material membrane elastic edge.

      Within the roll of the clamping adopts mechanical CAM automatic bilge type clamp, pneumatic motor through ball screw drive and rack on the linear slide rail move around the clamping material volume, convenient and quick; Volume is equipped with double location release automatic cutting non-stop high speed change device, rolling and cutting knife is motor driven swing arm type institutions, a cutting knife can meet the requirement and cutting. Winding adopts motor drive linear portable cutting, the cutting knife roller in addition to realize pressure cutting material needs, but also realize the contact and fixed interval winding function, make the big end of coil diameter flush winding obtained very satisfactory results.

 

      Production line take level elevating temperature range of more than 6 section of drying oven, oven inner guide roller for centralized all fixed-point lubrication, oven to overall opening and closing adopts electric control, wear feeding, cleaning and maintenance is very convenient. By adopting the combination of high temperature and super heat pump and infrared heating drying way, has carried on the optimization of hot air channel structure design, can fully to meet the needs of high speed coating drying, and achieved the effect of high efficiency, energy saving and environmental protection. Drying system adopts the intelligent fuzzy control technology, depending on the speed, coating technology and coating on the drying system of air volume and air pressure and wind calibrate intelligent automatic control. Using intelligent drying control system instead of manual operation, can more effectively control the coating curing effect and improve the efficiency of energy utilization.

      Servo motion control system adopts Siemens technology, realize accurate control of the whole machine tension, transmission part of the whole machine adopts virtual electronic axis control form. Main control system adopts Siemens D4x5 Simotion motion controller with high performance of 6 sl3120 series servo drives and high-performance 1 ph8 series servo motor as drive motor.Between motion controller and driver Drive CliQ is adopted to improve the high speed data communication, greatly improve the response speed of the transmission on the machine, which can realize accurate control of tension. PROFIBUS communication can realize external and real-time acquisition and output of each sensor signal based on high performance industrial touch screen, which can realize real-time intuitive human-computer interaction function. The machine industrial control system can realize automatic detection of coil diameter, working shaft automatic operation of coil diameter, rolling roll diameter/alarm, change volume prediction drive, automatic cutting, coating, rolling taper control, system fault detection, and other functions.

 

       The research and development success of this production line, greatly improved the packaging and printing machinery r&d manufacturing technology level, to meet the needs of high-end users. The product line is adopted by the advanced control technology and mechanical structure will also be transformation is applied to the drum gravure printing machine, compound machine equipment, such as further promoting China's printing and packaging industry and equipment manufacturing industry technical progress.
