Gravure printing machine,Which is widely used in the market, Since the printing industry is swept away by the Internet tide, the printing press industry is accelerating its decline. The most effective solution to decline is innovation.
In the past two years, with the improvement of the overall level of domestic gravure printing machinery manufacturing, domestic gravure printing equipment has also been constantly innovating, and achieved gratifying results. The following is a detailed description of the seven innovative technologies of gravure printing presses.
1. Automatic Roll-up and Roll-up Technology of Gravure Printing Machine
In the production process, the fully automatic up and down roll technology automatically raises the rolls of different diameters and widths to the clamping station through accurate measurement and detection, and then the lifting device automatically moves the finished rolls out of the equipment station. Automatically detect the weight of raw materials and finished products during the lifting process, which is connected with the production management work, replacing the manual handling method, which not only solves the bottleneck that the gravure printing machine needs to play the normal efficiency but cannot meet the auxiliary functions, but also greatly improves the production efficiency. , reducing the labor intensity of operators.
2. Automatic cutting technology of gravure printing machine
After the automatic cutting technology is adopted, the entire automatic cutting process only needs to place the material roll on the feeding rack, and the entire cutting action can be completed without manual participation in the subsequent cutting process. Taking the BOPP film with a thickness of 0.018mm as an example, the fully automatic cutting can control the length of the residual material of the roll within 10m. The application of automatic cutting technology in gravure printing machine equipment reduces the equipment's dependence on operators and improves work efficiency.
3. Intelligent pre-register technology for gravure printing machine
The application of intelligent pre-register technology is mainly to reduce the steps for operators to use the ruler to manually register the plate in the initial plate registration process, and directly use the one-to-one correspondence between the key grooves on the plate roller and the mark lines on the plate surface. The automatic confirmation of the bit realizes the initial version matching process. After the initial plate matching process is completed, the system automatically rotates the phase of the plate roller to the position where the automatic pre-registration can be realized according to the calculation of the material length between the colors, and the pre-registration function is automatically realized.
4. Gravure printing press semi-closed ink tank with lower transfer roller
Main features of gravure printing machine: It can effectively prevent the phenomenon of ink throwing under high-speed operation. The semi-closed ink tank can reduce the volatilization of organic solvents and ensure the stability of the ink during high-speed printing. The amount of circulating ink used has been reduced from about 18L to about 9.8L now. Since there is always a gap of 1-1.5mm between the lower ink transfer roller and the plate roller, in the process of the lower ink transfer roller and the plate roller, it can effectively promote the transfer of ink to the cells of the plate roller, so as to better realize the Shallow net tone restoration.
5. Intelligent Data Management System for Gravure Printing Machine
The main functions of the gravure printing machine: the on-site intelligent data platform can read the operating parameters and status of the selected machine control system, and realize the necessary monitoring and parameter backup storage; the on-site intelligent data platform can accept the process parameters and parameters issued by the remote intelligent data platform. Related order requirements, and implement authorization to decide whether to download the process parameters issued by the remote intelligent data platform to the control system HMI, and so on.
6. Gravure Press Digital Tension
Digital tension is to update the air pressure set by the manual valve to the required tension value directly set by the man-machine interface. The tension value of each section of the equipment is accurately and digitally expressed in the man-machine interface, which not only reduces the equipment in the production process. The operator's dependence, and the intelligent operation of the equipment is improved.
7. Hot air energy saving technology for gravure printing press
At present, the hot air energy-saving technologies applied to gravure printing machines mainly include heat pump heating technology, heat pipe technology and fully automatic hot air circulation system with LEL control.
1, Heat pump heating technology. The energy efficiency of heat pumps is much higher than that of electric heating. At present, the heat pumps used in gravure printing machines are generally air energy heat pumps, and the actual test can save energy by 60% to 70%.
2,Heat pipe technology. When the hot air system using the heat pipe technology is running, the hot air enters the oven and is discharged through the air outlet. The air outlet is equipped with a secondary air return device. Part of the air is directly utilized in the secondary heat energy cycle, and the other part of the air is used as a safe exhaust system. As this part of the hot air for safe exhaust air, the heat pipe heat exchanger is used to efficiently recycle the remaining heat.
3,Fully automatic hot air circulation system with LEL control. The use of a fully automatic hot air circulation system with LEL control can achieve the following effects: on the premise that the minimum explosion limit of LEL is met and the residual solvent does not exceed the standard, the secondary return air can be utilized to the maximum extent, which can save energy by about 45% and reduce exhaust gas. Row 30% to 50%. The exhaust air volume is correspondingly reduced, and the investment in exhaust gas treatment can be greatly reduced by 30% to 40% for the future ban on emissions.
