Rotogravure Printing Machine with Electronic Shaft Drive

This machine is a high-performance shaftless (electronic-shaft) modular gravure press that is suitable for rolled materials such as plastic film and paper. It has the advantages of short make-ready time, quick start, fast and accurate pre-register, steady printing speed, high registration accuracy, low residual solvent volume, low noise, and low power consumption. It can fulfill the basic 9-color printing function and printing+coating function on rolled film materials.

This machine is provided with a separate servo motor driving the printing cylinder to run simultaneously and execute vertical overprint operation. It needs shorter webbing route length and time between the units and help to ensure good and accurate register. Fast pre-registering method is used for its printing cylinder drive operation module, and acceptable register can be achieved in acceleration/deceleration modes. With pneumatic conic forme prop mechanism and horizontal automatic pre-lining up mechanism, it allows quick forme change and accurate positioning. With 3D adjustment doctor blade, frequency-variable horizontal play and pressurizing with double cylinders, easy, simple and fast replacement is possible. The impression roller is provided with automatic fast elevating device and limit device and impression rubber roller protection device during shutdown. With waste discharge device between color stations, harm to human body caused by solvents is reduced. Its ink circulation device is enclosed ink spraying device.

Power Distribution Cabinet for Control System

Its hardware in its control system has strong Ethernet communication functions. It includes SERCOS control ring, with optical fiber used as information transmission line, WIN-XP-based computing system and terminal operation platform, fitted with SYNAX200 electronic-shaft drive system made by BoschRexroth in Germany, special-purpose printing cylinder drive motor for German industry and high-precision absolute value encoder for memorizing the positions of printing cylinder. Control digital signals and analog signals are acquired and processed through PPC digital central processing unit. Field bus information exchange is available.

Disc-type Rewind/Unwind Reel

It is an independent external disc-type rewind/unwind mechanism with double positions that can rotate in both directions through 360° and has rotary reversing turret, and has automatic material change alarm, automatic drive for new web (reel) rolls, running at the same speed as the printing machine. It can automatically detect the adhesive tape on the end of web, which helps to reduce splice length. The reel of web is installed by using safety chuck/gas-expansion mounting clamp. With automatic material change alarm message and able to control accurate operation of the cutter and impression roller, the machine can correctly execute automatic cutting, splicing and web change.

Oven and Hot Air System

It has high-efficiency drying oven structure and discharge steady hot air with constant temperature. Waste heat can be recycled, so energy is saved and secondary pollution can be avoided. A low-noise and high-efficiency frequency-variable fan is applied for the printing machine and executes real-time adjustment of air volume and pressure. Reasonable and economic flow rate and pressure configuration, high efficiency and energy saving.
