A pneumatic tailstock center mechanism for a rewinding machine

Abstract

The present application relates to papermaking rewinding equipment technical field, especially a kind of rewinder pneumatic tailstock centre machinery.The linear guide assembly is fixed to the rack;Main sliding table is slidably assembled in linear guide assembly;Main drive cylinder is fixed to the rack, drives main sliding table to execute large stroke reciprocating motion;Slip guide rod is fixed to main sliding table along transverse;Centre sliding seat is slidably matched with slip guide rod;Side push cylinder is fixed to main sliding table, drives centre sliding seat to execute small stroke reciprocating motion along slip guide rod;Conical centre is rotatably assembled in centre sliding seat by rolling bearing group, and its outer conical surface is used to tightly press paper roll core tube and rotates synchronously with paper roll core tube.So, on the one hand, centre sliding seat is displaced along slip guide rod by side push cylinder, and the radial position of conical centre is accurately centered and adjusted;On the other hand, the clamping positioning requirement under different conditions is matched, to effectively compensate the manufacturing tolerance of paper roll core tube and loading installation deviation.
