Adhesive Label Printing Machine Brief Description:

DHL520 intermittent PS plate printing machine is a high-precision offset machine. It can print web with a maximum width of 520 mm, and coated paper, self-adhesive paper, paper-plastic composite material, etc. This machine is widely used in label, plastic film, color box, packaging paper and the like printing fields.

The intermittent offset label printing machine adopts Germany Rexroth Servo motor drives with automatic plate mounting and demounting, plate cylinder cocking function, pre-register function, delivering the fastest set-ups and changeovers, together with the fastest make-ready times in the industry (4-color changeovers are complete in just 5 minutes!). Additional advantages over the other similar presses include water-ink balance system and tension control system, which are Donghang’s exclusive patent, exquisite printing and fastest changeover, resulting in waste savings up for increased productivity. This press provides pre-register function before starting and touch screen register in printing with 63m/min running speed, which support benefit creating for customers.

Main features: 

1. Register system: each unit is driven by independent servo motor, which guarantees high-accuracy register during high speed running; the machine is equipped with stationary image monitoring system which can realize vertical and horizontal registering with less labor cost;

2. Stable printing pressure: rubber blanket cylinder is equipped with eccentric bearing having double-row tapered roller structure, which realizes reliable clutch operation and stable pressure; the forme cylinder and impression cylinder are equipped with tapered roller bearings, completely eliminating up-and-down movement caused by gap between bearings;

3. Continuous alcohol dampening system with auxiliary bridge roller: the continuous alcohol dampening system with auxiliary bridge roller ensures that the printing products are colorful and clear.

4. Positioning system: after inputting printing length at main console, each unit will automatically reach specified position, which reduces registering time and material waste;
