1. The frame is made of welded steel plate; 650 ° stress-free annealing; processed by Gantry Milling;
2. The upper silver linear guide rail is used as the carrier of the COTS' forward and backward movement, thus ensuring the precision of overprinter;
3. The COTS' forward and backward movement is realized by the oil cylinder;
4. The spindle box and tailstock are driven by RV (worm gear reducer) deceleration motor to move the left and right screw (trapezoid screw) in two directions to make the plate roll clamp and relax .
5.Cots for the initiative, driven by Cots Roll version;
6. The roller moves back and forth to realize the compression and separation between the roller and the Roller 7. The roller is driven by a hydraulic motor, and the speed is adjusted by a speed-regulating valve on the hydraulic station .
