Description
Technical field
This application involves inkjet printing field more particularly to a kind of spray head methods of adjustment of Drum inkjet printers.
Background technique
Existing ink-jet printer is mainly flat-panel printer, and printed material is laid on one flat plate, spray head trolley difference
Printed line by line along Y-axis and X-axis, to guarantee printing precision, spray head trolley needs to meet two required precisions: spray head cart base plate with
The depth of parallelism, the depth of parallelism of spray head and Y-axis (spray head trolley moving direction) of printing plate.This requirement usually relies on accurate processing
Location fit can reach, and if necessary to higher printing precision, usually adjust in such a way that screw is adjusted or is added gasket
It is whole.
Other than ink-jet printer, there is also have Drum inkjet printers.If above-mentioned adjustment mode is applied to drum-type
When ink-jet printer, it will be unable to spray head trolley being adjusted to correct position.This main difference is that flat-panel printer spray
Position deviation of the head trolley in X-axis and Y-axis will not change each spray head to the distance on printed material surface, and Drum inkjet is beaten
Because spray head cart base plate and printing drum are all cambered surfaces, position deviation of the spray head trolley in X-axis and Y-axis can all cause print machine
The distance on each spray head to printed material surface is inconsistent, so as to cause print quality decline.
Summary of the invention
It is beaten in view of this, it is an object of the invention to overcome the deficiencies of the prior art and provide one kind suitable for Drum inkjet
The spray head method of adjustment of print machine.
In order to solve the above-mentioned technical problem, the present invention is realized using following scheme:
A kind of spray head method of adjustment of Drum inkjet printers, is applied to Drum inkjet printers, and the Drum inkjet is beaten
Print machine includes that printing is bulging and spray head trolley, the spray head trolley are in arc-shaped, and the circumferencial direction phase with printing drum is distributed with thereon
Consistent multiple spray heads for spray printing, and on its cylindrical surface opposite with printing drum, the end close to printing drum two axial ends is each
Equipped with one group of arch counterbore, every group of arch counterbore includes multiple arch counterbores；
Include the following steps:
S1: (gap refers to the cylindrical surface of spray head trolley to the circle of printing drum to the gap between adjustment spray head trolley and printing drum
Perimeter surface), insertion operation is carried out to arch counterbore respectively using first group of test bar, so that first group of test bar can be whole
Inject arch counterbore；First group of test bar includes at least one first cylinder test bar, and the diameter of the first cylinder test bar is less than
The arc diameter of arch counterbore；
S2: insertion operation is carried out to arch counterbore respectively using second group of test bar, second group of test bar includes at least one
A second cylinder test bar, the diameter of the second cylinder test bar are greater than the diameter of the first cylinder test bar and are less than arch counterbore
Arc diameter；When the second cylinder test bar cannot be inserted into arch counterbore, adjustment terminates；If there is the second cylinder test bar can
It is inserted into arch counterbore, then repeatedly step S1 and S2, until the second cylinder test bar cannot be inserted into arch counterbore.
The vault and printing drum surface when being in gap lower deviation that the diameter of the first cylinder test bar is arch counterbore
Distance, the vault and printing drum surface when being in the gap upper deviation that the diameter of the second cylinder test bar is arch counterbore
Distance.By so set, final error is made not more than to adjust deviation.
The quantity of first cylinder test bar of first group of test bar is consistent with the quantity of arch counterbore.The inspection of first cylinder
The quantity for surveying stick is consistent with the quantity of arch counterbore, can be simultaneously to every when carrying out insertion detection using the first cylinder test bar
One arch counterbore is detected, and is facilitated the deviation of observation position and is adjusted correspondingly.
Every group of arch counterbore includes three arch counterbores, and is distributed alternately between three arch counterbores in circular arc.Three arches
Circular arc distributes alternately between shape counterbore, covers the entire arc surface of spray head trolley, guarantee each spray head and printing drum away from
From consistency.
Adjustment spray head trolley is respectively along X-axis and Z axis translation, rotation to adjust the gap between spray head trolley and printing drum；
The X-axis is vertical with the axis of printing drum and in same level, and Z axis is vertical with the axis of printing drum and same vertical flat
In face.By the adjustment along X-axis and Z axis, it may make the cylindrical surface of spray head trolley and the cylindrical surface of printing drum concentric.
Compared with prior art, the invention has the following beneficial effects: the application to pass through on test bar and spray head trolley
Arch counterbore adjustment can be realized, it is compact-sized, it is simple and reliable；It is detected by using two groups of test bars, there is easily behaviour
It is accurate that work, the high feature of Adjustment precision, and product test facilitate, and does not need precision detecting instrument.
