The utility model aims at realizing through the following technical scheme:

a printing roller structure comprises a roller, a rotating shaft, a support frame, a fixed sleeve, a connecting block and a clamping sleeve, wherein the roller is internally connected with the outer part of the rotating shaft, the two sides of the rotating shaft are provided with a first stepped shaft, the first stepped shaft is provided with a second stepped shaft, the second stepped shaft is provided with a third stepped shaft, the first stepped shaft is externally connected with the inner part of the clamping sleeve, the first stepped shaft rotates in the clamping sleeve, the clamping sleeve is provided with a second bulge, the support frame is internally provided with a second groove, the second bulge is matched with the second groove, the second bulge is connected with the second groove, the clamping sleeve is externally connected with the inner part of the connecting piece, one side of the connecting piece is provided with a first connecting plate, the first connecting plate is connected with the inner side of the support frame through a second fixing bolt, the other side of the connecting piece is provided with a second connecting plate, the second connecting, the support frame is internally provided with a first groove, a first bulge is matched with the first groove, and the first bulge is connected with the first groove.

The support frame internally connected No. two step shafts are outside, and No. two step shafts rotate inside the support frame, fixed cover is connected in the support frame outside, and fixed cover has the connecting block, and the connecting block passes through a plurality of fixing bolt joint support frame outsides, No. three step shafts of fixed cover internally connected, No. three step shafts rotate inside fixed cover.

Has the advantages that:

the pivot both sides have a step shaft, a step shaft has No. two step shafts, No. two step shafts have No. three step shafts, the step shaft makes the pivot rotate the in-process, area of contact increases, the atress is more even, it is more stable durable during the rotation, and a step shaft, No. two step shafts, No. three step shafts are respectively at the clamping sleeve, the support frame, fixed cover internal rotation, can not give birth to and break away from when making the rotation process more stable, and is rational in infrastructure, the clamping sleeve, the connecting piece, interconnect between the support frame, make overall structure more firm stable, and unsmooth embedded connection, when making firm in connection stable, have the location nature, can not take place the offset, and increase the support frame to its holding power, support its gravity downwards, and is rational in infrastructure. The clamping sleeve has the effect of clamping and stabilizing a first stepped shaft, so that the clamping sleeve cannot be separated from the first stepped shaft when rotating, the support frame has a supporting effect on a second stepped shaft and supports the downward gravity of the rotating shaft, the fixed sleeve has a fixing effect on a third stepped shaft, and the rotating process is more stable and reasonable in structure.
