Said apparatus there is the problem that when roller is bigger, roller heavier-weight, during tripping, roller clutch pressure cylinder 1 need to overcome roller weight and roller latch segment 3 to roller roller anvil 41 thrust with joint efforts could by roller clutch support arm 5 jack-up; Therefore, if selecting miniature bore cylinder as roller clutch pressure cylinder, owing to the power output of miniature bore cylinder is less, thus tripping needs can not be met; If selecting large-diameter cylinder, although power output is relatively big, can meet tripping needs, but it is big to take installing space, it is possible to cannot be able to install because of limited space.
Summary of the invention
In view of this, technical problem to be solved in the utility model is: provides a kind of roller locking pressure regulation device, adopts miniature bore cylinder can meet the needs of big roller clutch pressure.
For solving above-mentioned technical problem, the technical solution of the utility model is: roller locking pressure regulation device, including: roller locking cylinder and roller locking electromagnetic valve, it is connected to air inlet gas circuit between A mouth and the inlet chamber of described roller locking cylinder of described roller locking electromagnetic valve, between B mouth and the return-air chamber of described roller locking cylinder of described roller locking electromagnetic valve, is connected to return-air gas circuit;Described air inlet gas circuit is additionally provided with roller locking pressure and adjusts electromagnetic valve, pressure regulator valve and shuttle valve, the A mouth of P mouth and the described roller locking electromagnetic valve that described roller locking pressure adjusts electromagnetic valve is connected, described roller lock the pressure adjustment A mouth of electromagnetic valve, described pressure regulator valve, described shuttle valve an air inlet be in turn connected to form tripping air inlet branch road; Described roller locking pressure adjusts the B mouth of electromagnetic valve and is connected formation combined pressure air inlet branch road with another air inlet of described shuttle valve, and the gas outlet of described shuttle valve is connected with the inlet chamber of described roller locking cylinder.
Wherein, described roller locking cylinder has been arranged in parallel two.
Owing to have employed technique scheme, the air inlet gas circuit of roller of the present utility model locking pressure regulation device includes tripping air inlet branch road and the combined pressure air inlet branch road of parallel connection, after the roller clutch pressure adjusting apparatus of flexible printing machine have employed roller of the present utility model locking pressure regulation device, when roller tripping: tripping air inlet branch road is connected, the A mouth ventilation of roller locking electromagnetic valve, roller locking pressure adjusts the A mouth ventilation of electromagnetic valve, shuttle valve is opened, roller locking cylinder is in the state of stretching out, roller is in locking state, owing to tripping air inlet branch road is provided with pressure regulator valve, pipeline inner air pressure can be turned down, the coupling mechanism force to roller is reduced when keeping roller locking state, roller weight and roller latch segment to roller coupling mechanism force make a concerted effort diminish, therefore, adopt miniature bore cylinder can meet the needs of big roller clutch pressure as roller clutch pressure cylinder. when roller combined pressure: combined pressure air inlet branch road is connected, the A mouth ventilation of roller locking electromagnetic valve, roller locking pressure adjusts the B mouth ventilation of electromagnetic valve, shuttle valve is opened, roller locking cylinder is in the state of stretching out, and roller is in locking state, because the pipeline inner air pressure of combined pressure air inlet branch road is almost without loss, guarantee roller is applied bigger coupling mechanism force, meet and normally print the combined pressure requirement being.
Roller of the present utility model locking pressure regulation device adjusts electromagnetic valve, pressure regulator valve and shuttle valve by setting up roller locking pressure in former air inlet gas circuit, turn down the roller locking cylinder coupling mechanism force to roller during tripping, make the needs adopting miniature bore cylinder can meet big roller clutch pressure as roller clutch pressure cylinder, and simple in construction, easy to control, reliability is high.
