Detailed Description

Name: Computer High Speed Gravure Printing Machine (HPRT600-1200A) The machine is suitable for BOPP, PET, CPP, PVC and combined film and paper. Etc. With good printing performance. Its printing speed is 120m/min, while the mechanical speed is 130 m/min. 1. Seven-motor control system and PLC control system. The whole machine includes four segments closed loop control system. 2. The whole machine has four dancer rollers. 3. Main transmission device: The main transmission device adopts vector inverter to control the vector electric machine transferring each group of printing cylinder. (performance: Save electricity). 4. Block installing Device without Axis: This installation of blocks adopts air cylinder to pull the core of axis to install the blocks. The horizontal adjustment adopts the movement of screw. (Performance: Reduce time to replace the blocks, assure the boards to be concentric, improve the quality of product). 5. Structure of ink scraper: The ink scrapers can be adjusted up and down as well as its positions. The pressure of scraper adopts dual air pressure style. The horizontal movement adopts both the rotation of the electric machine and movement of cam. (Performance: Lengthen the service of the cylinders). 6. Printing pressure Structure: It adopts dual air cylinders to impress through lifting to a position, which is a protector for the air leakage of the cylinder and also a protector for falling of the cylinder when the machine stops working. Performance: Assure even pressure 7. Colour register principle: It adopts computer to control the synchronic electric machine to transfer the ball thread bar to adjust through reducing the speed to register color automatically. Performance: Lubrication rotated and high precision colors register. 8. The unwinding and rewinding structure: Their structures are both double working mechanism, the tension of unwind, rewind and traction adopts frequency vector inverter to control the line speed; Performance: Lower the rejects. 9. Drying system: The oven adopts centrifugal blower to blow and make suction, the electric tubes are installed averagely in each group of ovens at their blowing mouth to heat, the temperature is controlled by electric-heating controller; The negative pressure design inside the box, which prevents the outflow of the hot wind. 10. Cooling system: Adopts cool bellows to blow and the head roller adopts the way of water cooling to assure that the temperature of the films in a low degree. Main technical parameters Voltage: 380v three phase 50HZ Model : HPRT600A/ HPRT1200A Printing breadth: 600mm, 1200mm Max. Printing speed : 120m/min, 120m/min Diameter of roll materials : Φ600mm, φ600mm The horizontal adjustment of printing cylinder : 30mm, 30mm Overprint precision: ≤0.15mm, ≤0.15mm Total power: 75kw, 90kw Machine weight: 14T, 16T Overall dimension: 14800mmx2500mmx2500mm 14800mmx3100mmx2500mm
