Demand for carton printer

At present, because the products of carton machinery market tend to produce in many varieties and small batches, the change time has more and more influence on the production efficiency. Generally, the printing press adopts the track structure. When changing and erasing the plate, it needs to separate each color machine and merge them after changing the plate, which wastes a lot of time. The tilt adjustment of the printing plate is also very important. The printing of cartons requires high requirements for the printing plate. When it is impossible to install each color printing plate, it can ensure the center and level. The problem of the center can be adjusted by the axial adjustment of the printing roller, but the horizontal direction cannot be adjusted by the general machine. Therefore, when choosing a printing machine, it is better to choose a carton device with a plate tilt adjustment system. Generally speaking, the production efficiency is mainly restricted by the early preparation, printing speed, change time and other issues. Pre preparation includes plate adjustment, ink configuration, pressure adjustment, chromatic adjustment, etc. As it is the printing of cartons, the requirements of each link are relatively high, which is relatively time-consuming and laborious. Moreover, the speed is determined by the machine itself. Generally, due to the high requirements of the color registration accuracy and color superposition of the carton printing, the machine speed is not as fast as that of the ordinary carton printing. In addition, the cardboard of the cartons are mostly thin, and the requirements of the paper feeder are relatively strict, so the speed will be limited. In the production, the paperboard will be a little deformed, we can't require it to be flat, so we need the printing machine to adapt and correct the paperboard as much as possible in the whole process of paper feeding and printing, so as to achieve good utilization effect. Now the vacuum absorption is used in the paper feeder of the printing machine, and the suction belt conveying structure is used in the middle of the printing machine, which greatly reduces the requirements for the paperboard and achieves good results. www.chinacartonmachine.com
