Be shaped on one on the end face that receives gas pressure of said piston cylinder right ends respectively around circumference and end to end dashpot, the corresponding site of inner chamber of cylinder block then is shaped on and the matched step of this dashpot.
Said source of the gas is air pump or compression gas tank.
Motion among the present invention is synthetic by two parts: the one, and gear train passes to the right axle head 2 of intaglio press version roller 1 successively with power through connecting axle 20, clutch 21, make an edition roll shaft obtain needed rotating speed.The 2nd, source of the gas promotes piston cylinder 15 motions (being air-cylinder type roof pressure structure) after compressed air is imported cylinder body, produces moving along the piston cylinder axis direction thereby promote the right lobe 21-1 of clutch through the axial shifting block on the piston cylinder inwall 16; Consequently cause clutch 21 to break off (the right lobe 21-1 of clutch throws off with clutch left side lobe) and then cut off the driving force to the version roll shaft, perhaps clutch closes (right lobe 21-1 of clutch and the lobe engagement of a clutch left side) and the axial roof pressure power that strengthens clutch right side lobe makes edition roll shaft 1 elimination axially-movable gap.
The invention has the beneficial effects as follows: owing to adopted air-cylinder type roof pressure structure, make an edition roll shaft receive stable axial thrust, improved the accuracy that the version roll shaft rotates, guarantee to print raising, also improved service life the accurate and product quality of flower; And the motion of cylinder is very steady, and noiselessness has also prolonged service life.In addition, operation of the present invention is also very convenient.
