WH66 Offset Printing Machine

WH66 series printer is a high-quality large 4-open offset press, mainly suitable for high-quality color printing, text printing and ticket printing (installing NP devices). 1.Technical Features 1.1 No-action lever adopts paper-feeding linkage mode for water, ink clutch pressure and host pressure. The ink-ink clutch pressure can also be operated through the operation panel button, so there is no operation lever on the machine. 1.2 The multi-operation panel facilitates control on the operation side of the paper-feeding section and the delivery section, and the non-operating side of the equipment. A total of three operating panels are set to facilitate the operation. The operation can be performed both automatically and manually. 1.32-stage paper-feeding station can facilitate large-scale printing, and can improve the utilization of the printing press. Version 1.4 of the cylinder's positioning stop allows easy plate replacement. 1.5 Each part is equipped with sensors and other detection devices. In the event of a failure, the printing or paper feeding action will automatically stop and the fault location will be displayed on the main control panel, thus ensuring timely troubleshooting. 1.6 The modular NP device can be used for a simple loading and unloading operation with a special trolley. 2. Structural characteristics and performance 2.1 The paper feeding section continuously feeds the paper in two groups of nozzles. The angle of the paper suction nozzle can be adjusted, and the rotary valve controls the smooth switching of the air flow. 2.2 Overprinting unit The needle roller type overprinting mechanism adopts the upper front and upper pendulum methods. The well-designed cam that drives the rotary eccentric swing arm can guarantee the overlay accuracy under various speed conditions. 2.3 Ink supply and dampening system 19 ink sticks (including 4 different diameter ink rollers) ensure uniform ink supply; there are a total of 21 ink keys on the ink fountain to enable fine adjustment of ink volume; the ink fountain roller can be adjusted steplessly with the rotary knob. The dampening version adopts the water fleece sleeve method; 5 water rollers, 2 water rollers, and the independent motor-driven stainless steel water roller can realize stepless adjustment of water supply; the standard water cooling device can improve the quality of printed products. 2.4 Helical gears of high-carbon steel quenched and researched are used for the roller gear of the main engine; the outer gears are used to drive the drive system on the outside of the wallboard; the operating and non-operating side covers are sealed with silicone rubber, and the interior adopts the spray lubrication method. , To ensure the machine's ultra-quiet and super-durable. 2.3 Delivery Unit The standard equipment for the paper braking device, air blowing device and the separate adjustment of the loose paper sync cams ensure that the paper is properly delivered. 2.3 Stands Frames machined from 1 ton cast iron parts can support sophisticated mainframes for extended periods of time. 2.4 Electrical Control The main console is controlled by the CPU and controlled by the linkage between the operating panel and detectors. Variable frequency speed controller can achieve stepless speed change. 3.
