Line end is equipped with second solenoid valve；When needing to open clamp bar, control unit controls the first solenoid valve to open, when tracheal strips gas
For pressure when reaching scheduled threshold value, control unit controls the first solenoid valve to close, when needing to close clamp bar, control unit control the
Two solenoid valves are opened, and release gas, and clamp bar falls.
Optionally, elastic element one end connection guide rod, the other end are fixed on drum assembly.
Optionally, the elastic element is compression spring.
Optionally, several described guide rods are arranged in juxtaposition along the length direction of guide sleeve.
The beneficial effects of the invention are as follows：A kind of device being fixed to the flexible plate of gas promotion on roller that the present invention uses
And method, the drawbacks of avoiding three of the above mode, it can realize automatically opening and closing for clamp bar, and to processing and assembling
It is it is required that relatively low.And there can be extensive adaptability with the flexible plate of suitable for various size thickness, and process simple, dress
It is easy to maintenance with simple.And the ability with full width bread version can realize consolidating for version head and version tail with same clamp bar
It is fixed.

Specific embodiment：
With reference to each attached drawing, the present invention is described in detail.
The invention discloses a kind of drum assembly (see attached drawing 1,2,3,4,5), including：Roller 1, center are equipped with shaft 2, institute
Shaft 2 is stated equipped with stomata 3, the stomata 3 is used for external gas source；
Guide sleeve 4, in 1 module outer surface of roller；4 outer surface of guide sleeve is equipped with perforation；
Clamp bar 5, on the outside of 1 component of roller；
Several guide rods 6, one end connection clamp bar 5, the other end pass through perforation to go deep into guide sleeve 4；On the guide rod 6
Equipped with elastic element 7, described 7 one end of elastic element connects guide rod 6, and the other end is fixed on 1 component of roller, the elastic element
7 are used to provide the elastic force so that guide rod 6 stretches naturally；
Air bag 8, in guide sleeve 4；The air bag 8 is equipped with connector 9, and the connector 9 connects stomata 3；The air bag 8
For being filled with gas to lift clamp bar 5 or bleed off gas so that clamp bar 5 returns back to 1 component of roller under the action of elastic element 7
Outside.
A kind of device and method for flexible plate being pushed to be fixed on roller 1 with gas that the present invention uses, avoid more than
The drawbacks of three kinds of modes, can realize automatically opening and closing for clamp bar 5, and relatively low to processing and matching requirements.
For the stomata 3 by tracheae external gas source, the tracheae is equipped with control unit 10, the first solenoid valve 11 and sensing
Device 14, described control unit 10 are electrically connected the first solenoid valve 11 and sensor 14；Side siphunculus road, institute are additionally provided on the tracheae
It states side and leads to line end equipped with second solenoid valve 12；When needing to open clamp bar 5, control unit 10 controls the first solenoid valve 11 to beat
Open, when tracheal strips air pressure reaches scheduled threshold value, control unit 10 control the first solenoid valve 11 close, when need close clamp bar
When 5, control unit 10 controls second solenoid valve 12 to open, and releases gas, and clamp bar 5 falls.
Described 7 one end of elastic element connects guide rod 6, and the other end is fixed on 1 component of roller.The elastic element 7 is pressure
Spring.Several described guide rods 6 are arranged in juxtaposition along the length direction of guide sleeve 4.
When the present invention is implemented, inflation electromagnetism turns over opening, and gas enters air bag, expands air bag, and air bag, which jacks up, at this time is oriented to
Bar, the clamp bar installed on the guide bar lift.After air pressure reaches the pressure value of pressure sensor setting in air bag, electromagnetism is inflated
Valve is closed, and stops inflation, completes the process that clamp bar lifts.When clamp bar needs to be closed, i.e., clamp bar declines, pressure-releasing electromagnetic valve
Open, the compressed air in air bag is bled off rapidly, due in air bag without gas, deflated balloon, at this point, due to being pressed on guide rod
The effect of spring, guide rod move downward, and the clamp bar being connect with guide rod also simultaneously declines, when clamp bar is contacted with outer surface of cylinder
Afterwards, flexographic plate since compression spring also has decrement, can be just firmly secured to cylinder surface by clamp bar stop motion.
The foregoing is merely the preferred embodiment of the present invention, not thereby limit the scope of patent protection of the present invention, all
It is the equivalent structure transformation made with description of the invention and accompanying drawing content, is directly or indirectly used in other relevant technologies
Field similarly includes within the scope of the present invention.
