DEVICE FOR PREVENTING BACKLASH OF A FEED ROLL OF AN NC LEVELER FEEDER FOR INCREASING FEEDING ACCURACY OF MATERIALS WITH IMPROVED PRODUCTIVITY AND PROFITABILITY

摘要

PURPOSE: A device for preventing backlash of a feed roll of a Numerical Control leveler feeder for increasing feeding accuracy of materials is provided to supply uniform materials to an NC roll feeder from an NC leveler feeder.;CONSTITUTION: A device for preventing backlash of a feed roll of a Numerical Control leveler feeder for increasing feeding accuracy of materials comprises a transfer roll upper gear, a transfer roll lower gear, an idle upper gear(19), an idle lower gear(20), and a backlash preventing unit(30). The transfer roll upper and lower gears are formed in one end of an upper transfer roll and a lower transfer roll, respectively. The idle upper and lower gears are located to correspond to the transfer roll upper and lower gears. The backlash preventing unit connects the transfer roll upper and lower gears and the idle upper and lower gears to form one structure.;COPYRIGHT KIPO 2010
