Nantong Wenao Import And Export Co., Ltd
The device has outstand performance, the structure is compact, operate is easy. Up roller lift and turnover device used hydraulic drive. The motor drives two bottom rollers. This is the main drive and it realized by motor drive speed reducer with the help of triangle belt. The rolling flexibility is good, lift up roller test use shift sensor, and the shift shows as figure. Those about these raise producing efficiency and product quality.

II.The structure of machine
Using double oil vat drive directly, it’s max working pressure is 19.5Mpa. Rolling bearing and bearing base installed on the two sides of up roller. Position rod lifted up and bottom along vertical guides with the help of bearing. Installed shift sensor on the ends of bearing, and then to test elevate position. And show as figure. The material of up roller is 45# steel, and it done heat treatment.
Up roller
The bottom rollers drive motor with the help of triangle belt. The bottom roller transmitted power to a three level gear speed reducer. The gear speed reducer revolves bottom rollers with the help of output gear and bottom rollers gear. The material of bottom roller is 45# steel, and it done heat treatment.
Bottom rollers
Lifting up roller to highest place, the balance beam ( on the ends of up roller) fix up roller. So that the up roller on balance state with the help of bearing base and balance beam, and then we can easy to turnover and close turnover bearing base. The up roller lift to the highest place ,and this can test by SQ.
Turnover bearing
Using wield closed type frame base, it’s functions is good as the example bend-prevent, torsion-prevent,and inertia moment is large. So it’s easy to install machine and move.
Hydraulic system composed of gear pump, series of valves, accessory pipeline components and so on.
Hydraulic valve choose from Taiwan. The arrangement of pipeline is very easy, defend and shake bottom is easy too.
The system composed of three circuits, press adjust circuit, Symmetrical circuit, speed circuit.
Press circuit adjusts working pressure with the help the main valve. The working pressure is 19.5Mpa.
Synchronization circuit realize rough synchromesh bypass flow of up and by bottom lift split-flow and throttle valve. Readjusting up and bottom speed by throttle valve, and tested by shift sensor, synchromesh position accuracy attached 0.20mm of up roller.
Controlling turn over and resume of machine rack by speed circuit, and adjust speed by throttle valve.
Electrical system composed of electrical cupboard, button box. The power is AC 3-Phases
380V/50HZ. Main switch has the function about short protection and overload protection. The move distance of up roller test by sensor, show as figure, so it show directly, operate easily, and improve power.
