WT-B800-1100 Three Motors Computerized Gravure Printing Machine

Application:

It is suitable for BOPP, CPP, PET, PE, PVC and combined film and paper with the same properties. Its printing speed is 120m/min, while the mechanical speed is 130m/min.

Main Features:

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

2. 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.

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

4. 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: average pressure.

5. Chromatic mechanical handles: they adopt computer to control, synchronic motor to transfer the ball thread bar to adjust the chromatography through reducing the speed to register color automatically. Performance: rotate with lubrication and high precision in chromatography.

6. Material-receiving and feeding device: the material receiving and feeding adopts dual station. It can change the material and receive the materials automatically. The material-feeding shelf adopts magnetic powder tension control. The traction tension of material-receiving and feeding adopt frequency inverter vector to control the linear speed. The tension of material-receiving is controlled by moment motor. Performance: save materials, ink, solvent and energy for large quantities of printing products. And while the speed of material collecting is 120m/min, the most waste of material collecting is about 20meters, and it can save around 10% ink, solvent and energy resources. And lower the cost of the product largely.

7. Drying and cooling device: the drying system adopts fully-closed oven and outer second heating resource returning design. The temperature is controlled by intelligent temperature controller, which the returning roller adopts water-cooling device to control to assure the cooling of film. Performance: save electric power.
