Carton printing machine anilox roller in use for some time

?? Again, it’s a little shape-shifting.
?? Again, you’ll ask why, but it’s too complicated to explain. ?? Installation of mandrel at both ends
?? A lot of roller in the use of a period of time, the mandrel will break, why?? This is a problem with the mandrel installation,
?? The connection between the easy to fracture mandrels and the roller body is to weld the cross iron on the mandrels first, and then weld the cross iron in the mesh roller body, after the heat treatment of internal stress. ?? But this method is not advisable, the two rollers in a long time of extrusion state, after reaching the fatigue strength is extremely easy to break. ?? I learned that the hard way.
?? My current practice is to weld the mandrel and double blue, and then heat the roller body, and then put the blue into the heating and swelling roller body, after the roller body cooling tightly wrapped blue, and then spot welding a few times, but also to do annealing to stress treatment.
