Description

Printing roller inflating mechanism

Technical Field

The utility model relates to an aerating mechanism of a printing plate roller.

Background

In order to facilitate easy installation and removal of the printing plate roll, the amount of slidability between the roll and the roll mandrel is controlled by inflation and deflation. The shaft head of a plate roller mandrel in an early inflation structure is supported by a bearing, an air inlet hole is drilled on the shaft head, an inflation hole is drilled on a bearing seat, and when the plate roller mandrel needs to be inflated, air enters from the inflation hole and then reaches the air inlet hole on the shaft head through a gap between an inner hole of the bearing seat and the shaft head.
