Automatic Six Colors Screen Printing Machine Rotogravure

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 device adopts electrician frequency inverter of Shenzhen Inovance to control the vector motor, the transmission reaches to gear case and then the gears disconnected by the centrifugal gear.We can replace the intermediate manually to realize dual side printing. Performance:Convenient of registering ,.

 3. Printing cylinder installing Device without Axis:The installation of printing cylinders adopts air cylinder to pull the core of axis to install the cylinders. The horizontal adjustment adopts the movement of screw. Performance: reduce time of replacing the printing cylinders,assure the boards to be 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 velve 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. Chromatic Mechanical Handles: The vertical registration adopts clutch.

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 material-receiving 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 device: The oven has dual fans installed on the board and the air-circulation and heat-recycle device. The electric quartz tubes are installed averagely in each group of ovens at their blowing mouth to heat .The temperature is controlled by intelligent thermo-controller. Every top oven adopts centrifugal fan to cool the film to assure the cooling of film. Performances: save electric power.
