7 Motor Web Offset Printing Machine Fully Automatic Plastic Film

Specifications :

Introduction:

1. Usage: It is suitable for BOPP, PET, CPP, PVCD and combined film and paper with the same properties. Its printing speed is 80- 100m/min, while the mechanical speed is 120m/min.

2. Main transmission device:The main transmission adopts electrician frequency inverter from Shenzhen Inovance to control the vector motor, transferring each group of printing cylinders. Performance: save electric power.

3. Printing cylinder installing Device without Axis:The Installation of printing cylinders adopts air cylinder to pull core of axis to install cylinders. Horizontal adjustment adopts movement of screw. Performance: reduce time of replacing the printing cylinders,assure boards concentric and improve the quality of product.

4. Structure of ink scraper: The ink scrapers can be adjusted up and down as well as its positions. The pressure of scraper is controlled by dual air cylinder .The horizontal movement adopts both the rotations of the motor and movement of cam. Performance: lengthen the service of the printing cylinders.

5. Pressing lifting Structure: The pressing lifting adopts dual air cylinder to increase the pressure and solenoid valve to locate the position, which is a protector for the air leakage of the cylinder when the machine stops working .Performance: Assure the average of pressure and color chromatic aberration.

6. Chromatography manipulator:It adopts computer to control, synchronic motor to transfer the ball thread bar to adjust the chromatography up and down through reducing the speed to register color automatically and directly. Performance: reduce the cost,rotate with lubrication and high precision in chromatography.

7. Material-Receiving and Feeding Device:The material receiving and feeding adopts dual station. The materail-feeding shelf reverse manually.The traction tension of the receiving and feeding material device adopts automatic tension controlling. The materialreceiving device adopts moment motor controlling,the material-feeding adopts magnetic powder tension controlling. Performance: Reduce the waste materials and lower the cost.

8. Drying and cooling structure: drying is realized by the heat recycling air device with a blowing & absorbing centrifugal fan mounted outside; the electric heating quartz tubes are heated at the blow-off nozzle in each set of drying oven; temperature is controlled by intelligent temperature controller, and centrifugal fan is used to cool each set of upper drying oven so as to make sure the film cooling. Characteristic: save power and enhance drying function.
