Specific implementation mode
The utility model is described in further detail with reference to the accompanying drawings and examples.
As shown in Fig. 2, a kind of structural schematic diagram of the print roller provided for the utility model embodiment, including：Section is
Circular printing roll shaft 1 and printing axle sleeve 2, printing roll shaft 1 is including the first support portion 101 and is located at 101 both ends of the first support portion
The second support portion 102, the diameter of the first support portion 101 is more than the second support portion 102, and printing axle sleeve 2 is sheathed on the first support
Portion 101.
As shown in figure 3, the structural schematic diagram of the print roller set provided for the utility model embodiment, printing axle sleeve 2 can root
It is replaced according to actual needs.Second support portion 102 of printing roll shaft 1 with the support member of printing machine for connecting, by this reality
The print roller provided with new embodiment is installed in printing machine.
As shown in figure 4, the structural schematic diagram of the printing roll shaft provided for the utility model embodiment, along the second support portion
