Specific embodiment
In order to illustrate more clearly of the utility model embodiment and technical solution of the prior art, attached drawing will be compareed below
Illustrate specific embodiment of the present utility model.It should be evident that the accompanying drawings in the following description is only the one of the utility model
A little embodiments, for those of ordinary skill in the art, without creative efforts, can also be according to these
Attached drawing obtains other attached drawings, and obtains other embodiments.In addition, being related to belonging to for orientation only represents opposite between each component
Position relationship rather than absolute positional relation.
It please refers to Fig.1.The air system of the utility model embodiment, for printing work area 9, including being used for printer
Make area 9 and the positive pressure system of positive pressure gas flow and the negative pressure system for providing printing work area 9 negative pressure gas flow are provided；Printing work
Area 9 is equipped with inlet end and outlet side；Positive pressure system is included for the main positive pressure being connect with inlet end that produce positive pressure gas flow and equal
Machine 1 and spare positive press 2, negative pressure system include for the main Negative pressure machine 3 being connect with outlet side that generate negative pressure gas flow and equal and
Spare Negative pressure machine 4.
Due to being equipped with a large amount of printing equipment in printing work area 9, these printing equipments are required for negative pressure gas flow to make mostly
For sucker, sucker is made to generate certain negative pressure when being contacted with paper, when sucker and paper actuation, due to sucker and paper
The air inlet of contact jaw is blocked by paper, can not air inlet, suction cup interior negative pressure is caused to become larger, at this moment, positive pressure system provide just
Pressure gas stream will be directly identical with negative pressure gas flow, plays the role of pressure buffer, while can also be by adjust positive pressure gas flow
The mode of size controls negative pressure gas flow to 9 negative pressure value of printing work area, not only good to be attracted paper, but also provide again
Suitable pressure value, not only ensure that the stability of print system negative pressure gas flow, but also improve pressure controlled operational and sensitive
Property.
Positive pressure system and negative pressure system further include the valve 6 of controllable positive pressure gas flow and negative pressure gas flow size.In master just
The gas outlet of press 1 and spare positive press 2 is equipped with valve 6, more rapidly directly to control gas output；In main 3 He of Negative pressure machine
The air inlet of spare Negative pressure machine 4 is equipped with valve 6, so as to quick directly control air inflow.When negative pressure value is excessive in sucker, it is
Avoiding paper distortion, either the gas outlet valve 6 of the positive press 1 of master and spare positive press 2 can be tuned up or will be main by rupture
The air inlet valve 6 of Negative pressure machine 3 and spare Negative pressure machine 4 is turned down, reduces negative pressure value in sucker；When negative pressure value is too small in sucker,
In order to avoid paper is fallen, the gas outlet valve 6 of the positive press 1 of master and spare positive press 2 can be turned down or by main Negative pressure machine 3
It is tuned up with the air inlet valve 6 of spare Negative pressure machine 4, increases negative pressure value in sucker.
Negative pressure system further includes the negative-pressure cup 5 for buffer gas flow pressure.The purpose for setting negative-pressure cup 5 is to ensure to bear
Steady air current in pressure system and positive pressure system mitigates, and prevents air-flow from being generated due to the changed power of positive press or Negative pressure machine
Moment excessive air-flow is attracted quality so as to influence paper.It is main meanwhile when 9 workload of printing work area is smaller or shutdown status
Negative pressure machine 3 in advance can generate negative-pressure cup 5 certain negative pressure value, which can ensure that 9 workload of printing work area is smaller
Or demand when shutting down, additional production cost is caused so as to avoid Negative pressure machine continuous firing.
Pressure warning unit 7 is additionally provided on negative-pressure cup 5.Pressure warning unit 7 can be with the pressure in actual response negative-pressure cup 5
Power can control the on off state of Negative pressure machine according to pressure in negative-pressure cup 5, at the same can also when negative pressure value is excessive in pipe,
During beyond default warning value, alarm will be sent out, notifies staff.
Further include group control device.Group control device be a remotely controlled electronically screen, can by the electrical screen to master positive press
1st, each valve 6 is controlled and is monitored in spare positive press 2, main Negative pressure machine 3, spare Negative pressure machine 4, negative-pressure cup 5 and system.No
The state of grasp internal system each position that only can be immediately, but also timely system can be controlled, such as adjusts
The aperture size of valve 6, the on off state of control device.Simultaneously the group control device also with equipped with warning function, when system internal pressure
When force value is more than the pressure early warning value set in advance, group control device meeting autostop is simultaneously emitted by alert notice staff, keeps away
Some unnecessary losses and the danger in production process are exempted from.
Main positive press 1 is in parallel with spare positive press 2；Main Negative pressure machine 3 is in parallel with spare Negative pressure machine 4.Main positive press 1 and spare
The purpose of positive press 2, main Negative pressure machine 3 and spare Negative pressure machine 4 access system in parallel is when main positive press 1 or main Negative pressure machine 3 damage
When can not badly work, spare positive press 2 or spare Negative pressure machine 4 can be opened immediately, reached lasting to being provided in printing work area 9
Air source, ensure that stable gas pressure.
Positive pressure system and negative pressure system are additionally provided with pressure sensor 8.It can be convenient for the pressure value in real-time monitoring system
Pressure is adjusted, and is conducive to the normal table production in printing work area 9.
The above content is combine specific preferred embodiment further detailed description of the utility model, it is impossible to
Assert that the specific implementation of the utility model is confined to these explanations.For the ordinary skill of the utility model technical field
For personnel, without departing from the concept of the premise utility, several simple deduction or replace can also be made, should all be regarded
