Description
Technical field
The present invention relates to printing equipment technology, refer in particular to a kind of gripper mechanism of adjustable negative pressure position.
Background technique
In print field, in particular to online spray printing process, when drum drive, in order to guarantee that the paper of transmission can be with rolling
Cylinder is sufficiently bonded, and is often adding negative pressure device on barrel, the paper being transmitted can be sucked, because being rotation fortune
Dynamic, being transmitted object is gradually to contact with barrel, so the control of negative pressure is just very crucial.In currently available technology, have logical
It crosses mechanical spring and vacuum cavitations is carried out to each negative pressure hole, then negative pressure hole is opened when having a paper transmission, when being driven without paper then
Negative pressure bore closure, but because mechanical spring is easy to block into dust, irregular operating is caused, there are also there are many quantity of negative pressure hole,
The quantity of mechanical spring need to be matched with negative pressure hole, then equipment cost is very high, and the difficulty of construction is also bigger.
Summary of the invention
It is an object of the invention to be directed to the existing state of the art, a kind of gripper mechanism of adjustable negative pressure position is provided,
Gradual fitting and gradual opening function can be formed according to paper pass order, guarantee sheet stabilizers transmitting.
In order to achieve the above objectives, the present invention adopts the following technical scheme:
The present invention is a kind of gripper mechanism of adjustable negative pressure position, mainly has roller, seaming, is evenly distributed on the roller
Several negative pressure holes further include vacuum cavity, and each negative pressure hole passes through corresponding tracheae and connect with vacuum cavity, the vacuum cavity
In be equipped with piston, vacuum cavity end connects negative pressure generator, and the piston is linked by linkage mechanism and roller.
In above scheme, linkage mechanism is cam mechanism, and linkage mechanism connect realization with roller and operates synchronously.
Further, rotary joint is equipped in each tracheae.
Further, each tracheae is uniformly distributed in the cavity wall of vacuum cavity.
Further, each tracheae is connect by the connector through vacuum cavity with vacuum cavity.
Further, vacuum cavity is connect by total pipeline with negative pressure generator.
Further, each connector is distributed in a ring in vacuum cavity cavity wall, and in vacuum cavity piston movement
Several ring shape connectors are formed on path.
Further, on roller direction of rotation, i.e. the first row negative pressure hole that is contacted at first with paper of seaming side and negative pressure
One ring shape connector of cavity bottom is correspondingly connected with, and second row negative pressure hole is correspondingly connected with the second ring shape connector, according to
It is secondary to analogize.
The invention has the benefit that making contact of the negative pressure hole according to paper with roller using piston combination negative pressure technique
Sequence is successively opened, and is successively closed according to the separation sequence of paper and roller, keeps paper operation more stable；And the equipment is compared
In the negative pressure hole of tradition machinery spring, cost is lower, and stability is higher.
Detailed description of the invention:
Accompanying drawing 1 is the structural representation of the present invention；
Attached drawing 2 is the operating status figure of roller in the present invention.
Specific embodiment:
It please refers to shown in Fig. 1, Fig. 2, is the structural schematic diagram for the preferred embodiments of the invention, the present invention is a kind of adjustable negative
, mainly there are roller 1, seaming 10 in the gripper mechanism for pressing position, several negative pressure holes 11 is evenly distributed on the roller 1, further include
Vacuum cavity 2, each negative pressure hole 11 are connect by corresponding tracheae 3 with vacuum cavity 2, and piston is equipped in the vacuum cavity 2
21,2 end of vacuum cavity connects negative pressure generator 4, and vacuum cavity 2 is connect by total pipeline 20 with negative pressure generator 4.The work
Plug 21 is linked by linkage mechanism 5 and roller 1.Specifically, linkage mechanism 5 is cam mechanism, linkage mechanism 5 passes through drive rod 8
It is connect with piston 21, and linkage mechanism 5 connect realization with roller 1 and operates synchronously, i.e. the rotation of roller 1 is turned around, and piston 21 is linking
Uplink and downlink are completed under the drive of mechanism 5 in vacuum cavity 2, totally two strokes.
It is equipped with rotary joint 31 in each tracheae 3, when roller 1 rotates, the connecting pin of tracheae 3 and roller 1 is revolved with roller 1
Turn, and rotary joint 31 then can avoid each tracheae and knot.
Each tracheae 3 is uniformly distributed in the cavity wall of vacuum cavity 2, and each tracheae 3 is by the connector 22 through vacuum cavity 2 and bears
Cavity 2 is pressed to connect.Specifically, each connector 22 is distributed in a ring in 2 cavity wall of vacuum cavity, and the piston in vacuum cavity 2
Form several ring shape connectors on 21 motion path, effect is, on 1 direction of rotation of roller, i.e., 10 side of seaming is most
First the first row negative pressure hole contacted with paper and a ring shape connector of 2 bottom of vacuum cavity are correspondingly connected with, and second row is negative
Pressure hole is correspondingly connected with the second ring shape connector, and so on, it can be during roller 1 drives paper rotation, on roller 1
The sequencing that the negative pressure function of each row's negative pressure hole 11 opens or closes is different, and realization is gradually opened and gradually closed.
Specific workflow: stamping uniform negative pressure hole 11 on 1 surface of roller, and all negative pressure 11 are passed through corresponding tracheae
3 are connected to one end of rotary joint 31, and the other end of rotary joint 31 is connected to vacuum cavity 2 by another section of tracheae 3
In cavity wall, negative pressure generator 4 is connect by total pipeline 20 with vacuum cavity 2, is made to generate certain negative pressure in vacuum cavity 2, be born
Piston 21 in pressure cavity 2 is connected on linkage mechanism 5 by drive rod 8, and linkage mechanism 5 is mounted on roller 1, with roller 1
It operates synchronously.When the seaming 10 of roller 1 bites paper, the paper at 10 position of seaming is first contacted with roller 1, and others do not connect
Touching, at this moment piston 21 starts bottom-up under the driving of linkage mechanism 5, gradually to the negative pressure hole of roller 1 since seaming 10
11 provide negative pressure, accomplish have paper and roller 1 just to have negative voltage supply when contacting, avoid the problem of paper tail tilts.Pass through piston
The breadth of the adjustable paper of stroke of 21 drive rods 8, when paper breadth becomes smaller, the place of paper is not then without negative pressure.
Certainly, illustrated above is only better embodiment of the present invention, and use scope of the invention is not limited with this, therefore,
It is all made in the principle of the invention it is equivalent change should be included within the scope of the present invention.
