Description
Technical field
The utility model relates to a kind of accessory of printing machine and equipment, controlled more particularly to a kind of with counter signals
Automatic dampening device.
Background technique
In offset print technology, press printing is that printing plate is first gone up water (when in water using oil-water incompatible principle
Joined after damping agent also referred to as fountain solution) inking again, i.e. printing plate is hydrophilic substrate without areas, and areas is water repellent base
Material, for printing plate first after upper water, no areas would not viscous oil ink.There is one to put on water on each printing seats of offset printing equipment
Dampening device, the mode of usual damping have two kinds, and one is upper water in sink is immersed with damping roller, second is with water pump to spray
Head pressurization water spray, water atomisation is sprayed on printing plate.First way is since upper damping roller is soaked in water always, when printing machine speed
The amount for spending fast Shi Shangshui will increase, and upper discharge reduction when speed is slow needs to adjust water and stablizes print speed printing speed, print speed printing speed
Damping bad phenomenon is be easy to cause when variation.For the second way since water-aspirator pressure is non-adjustable, the speed of water spray is non-adjustable, works as print
When brush machine velocity variations, it will result in water on printing plate and change, also be easy to cause damping bad phenomenon.Damping is bad to be will cause
Printed matter is scrapped because picture and text lack or drag black phenomenon.The mode of above-mentioned two kinds upper water dampings not can solve print speed printing speed variation
When the bad problem of damping, cause the waste of printed matter.
Utility model content
The automatic damping for the upper water that the purpose of the utility model is to provide a kind of to be controlled with counter feedback signal fills
It sets, solves the problems, such as that printing machine damping in print speed printing speed variation is bad.
The automatic dampening device described in the utility model controlled with counter signals, by upper water dispenser structure, water spraying mechanism, control
Mechanism composition processed；Upper water dispenser structure includes a sink and at least one upper hose；Water spraying mechanism includes at least one nozzle, nozzle
It is connect by tracheae with a solenoid valve, solenoid valve is connected with compressed air source；Control mechanism includes a counter, a sense
Answer head and a signal wheel.
The upper water dispenser structure is mounted on the obliquely downward of the forme roller of printing machine, and water spraying mechanism is mounted on the upper of water dispenser structure
Side, the upper orifice of the nozzle face upper hose of upper water dispenser structure, and position can upper and lower, left and right adjustment；Solenoid valve and counter electricity
Property connection；Counter and inductive head are electrically connected；Signal wheel is installed on a drive roll end in printing machine.
When it is that forme roller is longer that printing plate is wider, need to use multiple nozzles, multiple nozzles form nozzle sets, multiple nozzles
It connects on a tracheae, tracheae is connect with a solenoid valve, i.e., by a solenoid valve control；There is a upper water under each nozzle
Pipe, nozzles multiple in this way while upper water are to cover entire printing plate breadth.
It is opened the beneficial effects of the utility model are: counter can provide signal control solenoid valve, nozzle is made to spray compression
Air generates negative pressure when compressed air high speed ejection by upper hose and water is sucked out, then is blown out by the compressed air of high speed misty equal
Damping is realized on the even printing plate for being sprayed on print roller outer surface；It can be obtained by upper and lower, left and right adjustment nozzle and upper hose mouth position
To optimal atomizing effect；And the signal that counter provides is to sense signal wheel notch by inductive head and generate, and signal
Wheel is mounted on printing machine drive roll, and when press speed variation, the signal that signal wheel provides also while changing, and makes electromagnetism
The frequency that valve is opened is the speed of water spray also with variation, and such printing plate can just obtain stable upper water, well solve
Damping bad problem when print speed printing speed changes.To improve production efficiency, production cost has been saved, has been had very strong practical
Property and wide application prospect.
Detailed description of the invention
Attached drawing 1 is the structure principle chart of the utility model.
Accompanying drawings symbol description: 1-upper water dispenser structure；2-water spraying mechanisms；3-control mechanisms；4-forme rollers.
Specific embodiment
The utility model illustrates specific embodiment using a kind of embodiment.
As shown in Fig. 1, the automatic dampening device described in the utility model controlled with counter signals, by upper water dispenser structure
1, water spraying mechanism 2, control mechanism 3 form.Upper water dispenser structure 1 includes a sink 11 and at least one upper hose 12；Water spraying mechanism 2
Comprising at least one nozzle 21, nozzle 21 is connect by tracheae with solenoid valve 22, and solenoid valve 22 is connected with compressed air source；Control
Mechanism 3 includes counter 31, inductive head 32 and signal wheel 33.
The upper water dispenser structure 1 is mounted on the obliquely downward of the forme roller 4 of printing machine, and water spraying mechanism 2 is mounted on water dispenser structure 1
Top, the upper orifice of the 21 face upper hose 12 of nozzle of upper water dispenser structure 1, and position can up and down, left and right adjustment；Solenoid valve 22
It is electrically connected with counter 31；Counter 31 and inductive head 32 are electrically connected；Signal wheel 33 is installed on a master in printing machine
Dynamic roller end head.
When forme roller is longer, needing to use multiple nozzles 21 and form nozzle sets, multiple nozzles 21 connect on a tracheae,
Tracheae is connect with a solenoid valve 22, i.e., is controlled by a solenoid valve 22；There is a upper hose 12 under each nozzle 21.
The working principle of above-mentioned apparatus is: when printing machine operation, the counter 31 of control mechanism 3 provides signal control spray
The solenoid valve 22 of water dispenser structure 2 is opened, and sprays compressed air from nozzle 21, and when compressed air high speed ejection generates negative pressure, is passed through
Water is sucked out in upper hose 12 from sink 11, then blows out the misty print for being uniformly sprayed on 4 outer surface of print roller by the compressed air of high speed
In version, optimal atomizing effect can be obtained by upper and lower, left and right adjustment nozzle 21 and 12 mouthfuls of upper hose of position；And counter 31
The signal provided is to sense that 33 notch face of signal wheel is generated by inductive head 32, by adjusting the frequency of 31 output signal of counter
The number of the unlatching of solenoid valve 22 after the signal of every generation of inductive head 32 can be obtained in rate.Since signal wheel 33 is mounted in printing machine
On drive roll, when press speed variation when, the signal that signal wheel 33 provides also simultaneously change, solenoid valve 22 unlatching frequency
With variation, such printing plate can just obtain stable upper water.
This new structural automatic dampening device is processed using common material, is suitable for industrialized production.
