The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art. The following describes an embodiment of the present invention according to its overall structure.

Referring to fig. 1-4, a roller structure of an offset printing machine includes a supporting frame 1, a roller 2, a fixture block 3, a motor 4, a reel 5, a pull rope 6, a first spring 7, a cleaning brush 8, a first chute 9, a slider 10, a limiting block 11, a groove 12, a second spring 13 and a second chute 14; support frame 1 is provided with two, recess 12 and second spout 14 are seted up respectively at support frame 1's top, cylinder 2 and fixture block 3 are installed respectively to recess 12's inside, the internally mounted of second spout 14 has second spring 13, stopper 11 is installed to second spring 13's one end, first spout 9 has all been seted up to one side of two support frames 1, slider 10 and first spring 7 are all installed to the inside of two first spouts 9, install clearance brush 8 between two sliders 10, support frame 1's surface mounting has motor 4, reel 5 is installed through the pivot to motor 4's output, reel 5's outer surface connection has the stay cord 6 that extends to first spout 9 inside and be connected with slider 10.

Please refer to fig. 1, fig. 2 and fig. 4, the fixture block 3 is located above the roller 2, and a handle is installed at the top of the fixture block 3, so as to limit the roller 2 through the fixture block 3, and meanwhile, the fixture block 3 can be pulled through the handle; stopper 11 is located the top of fixture block 3, and stopper 11 passes through second spring 13 and second spout 14 sliding connection to thereby stopper 11 slides the back in second spout 14 through the extrusion second spring 13 and carries on spacingly or open fixture block 3.

Please refer to fig. 1-3, the cleaning brush 8 is connected with the first sliding chute 9 through the sliding block 10 and the first spring 7 in a sliding manner, and the cleaning brush 8 contacts with the roller 2, so that the cleaning brush 8 can clean the roller 2 after sliding in the first sliding chute 9 through the sliding block 10 and the first spring 7; the pull rope 6 is provided with two, and one end of the pull rope 6 is located inside the first spring 7, so that the connection of the cleaning brush 8 through the pull rope 6 is more stable.

The working principle is as follows: firstly, when the roller 2 is used for printing, a worker starts the motor 4, the motor 4 drives the rotating shaft to rotate forwards, the rotating shaft drives the reel 5 to rotate forwards, the reel 5 rotates forwards to wind the pull rope 6, the pull rope 6 pulls the sliding block 10 in the winding process, the sliding block 10 extrudes the first spring 7 to slide in the first sliding groove 9, meanwhile, the sliding block 10 drives the cleaning brush 8 to be away from the roller 2, so that the influence on the roller 2 caused by the contact between the cleaning brush 8 and the roller 2 in the working process is avoided, then, the motor 4 drives the rotating shaft to rotate backwards after the working process is finished, so that the reel 5 releases the pull rope 6, the first spring 7 recovers elasticity and pushes the sliding block 10 to move after the pull rope 6 is released, the cleaning brush 8 is in contact with the roller 2, the roller can be cleaned by the cleaning brush 8, when the roller 2 needs to be overhauled or replaced, the worker can extrude the limiting block 11, make stopper 11 extrusion second spring 13 slide to second spout 14, and then make stopper 11 open recess 12, staff alright afterwards through handle pulling fixture block 3, alright take out cylinder 2 after taking out fixture block 3 and overhaul or change, later when installing cylinder 2 to recess 12 in, thereby second spring 13 receives to recover elasticity after the compression and promotes stopper 11 and remove to one side of fixture block 3, and then makes stopper 11 carry out spacing fixed to fixture block 3.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
