Description
Technical field
The present invention relates to a kind of printing equipment and a kind of arrowband printing machine.
Background technology
In printing machine, especially in flat plate printing apparatus and gravure apparatus, one is usually set in printing cylinder
Roller trough.This roller trough works as a clamping slot in many cases, for accommodating a cylinder-packing being clamped on roller
End.The cylinder-packing can be a printing plate or a blanket.
Especially in flexible plate printer, in the cylinder-packing of a winding roller body of roll, such as one be bonded in the roller body of roll
On or can there are a gap (so-called notch between the leading edge of soft version printing plate (stereotype) and trailing edge that magnetically keep on it
(Gap))。
When the roller is rolling on one adjacent roller, the roller trough or the notch cause a so-called groove punching
Hit or notch shock.When in the opposed locations that the roller trough or the notch are in adjacent roller, then in two rollers
Between compression shock formula decline.The defects of this occurs when each roller turns round and result in visible in printing figure.
In order to reduce the defects of printing figure, from known in the art and for example described in 27 53 487 A1 of DE,
The supporting arrangement of the printing cylinder is supported by a gas spring, so as to damp the vibrations of the printing cylinder.But air pressure
The setting of spring shows as the solution of a consuming, it must pay attention in the design of printing machine.The solution is not
It is suitable for the repacking of printing equipment.
The content of the invention
According to the present invention, it is proposed that a kind of printing equipment, for printing with shape or individual shape base material, having one can enclose
Around a pivot axis printing cylinder and can substantially be put down with the pivot center of the printing cylinder around one with one
Capable pivot axis to print roller, wherein, the printing cylinder and described pair print roller between form a pressroom
The gap and base material is printed, wherein, two fringe regions of the printing cylinder or described pair of print roller in its periphery
It is middle that there is an elasticity, annular damping element respectively, and the printing equipment is associated with the damping with least one
The regulating element of element, wherein, the damping characteristic of corresponding damping element can be adjusted by least one regulating element.
According to the present invention, it is also proposed that a kind of arrowband printing machine, has one to be filled according to the printing described in preceding solution
Put.
The task of the present invention is propose a kind of printing equipment and a kind of arrowband printing machine, it eliminates existing at least in part
There is the shortcomings that technology, and provide a kind of simple and of low cost at the same time solution, for reducing groove impact or lacking
Influence of the mouth impact for printing figure.
The task is by a kind of printing equipment with feature in above-mentioned technical proposal and by one kind according to foregoing side
Arrowband printing machine described in case solves.
Printing equipment according to the present invention be used for printing one with shape or individual shape base material, particularly for manufacture label or
Folded box, has a printing cylinder that can surround a pivot axis, and can surround one and the printing cylinder with one
The substantially parallel pivot axis of pivot center to printing roller, wherein, in the printing cylinder and described pair of print rolling
A printing gap is formed between cylinder and the base material is printed.The printing equipment can especially be implemented to fill into flexographic printing
Put.The printing cylinder can have a roller trough or a notch in the case.In an advantageous manner, the printing cylinder or
Described pair of print roller is in two fringe regions of its periphery, that is to say, that by proximal end face, respectively with an elasticity, annular
Damping element.The damping element winding roller pushes away in other words to be attached on the roller.In addition, in the printing equipment
It is middle that at least one regulating element for being associated with the damping element is set, wherein, the damping characteristic of corresponding damping element and
There is outside diameter to be adjusted by least one regulating element if necessary.
It is advantageously improved in printing equipment one kind according to the present invention in scheme, corresponding damping element is implemented into fluid
The hose made of elastic material of filling, and at least one regulating element sets and is used to change in corresponding hose
Pressure.By varying the pressure in corresponding hose, can change in a straightforward manner with method the hose diameter and by
This influences the rolling behavior of the printing cylinder and described pair of print roller.In a kind of favourable designing scheme of the flexible program
In, the regulating element includes a pump or a compressor, it can be manipulated by an equipment control device.It can make in the case
The fluid in corresponding hose is used as by the use of air or hydraulic fluid.
In a kind of designing scheme of replacement of printing equipment according to the present invention, corresponding damping element is implemented into by bullet
Property material, ring especially made of rubber.In addition, arrange a regulating element for being used to make corresponding annular strain to each ring.It is logical
The deformation of corresponding ring is crossed, the diameter of the ring, its damping characteristic can be influenced and therefore influence the printing cylinder and described
Rolling behavior to printing roller.In the case, two rings receive the printing cylinder or described couple of the whole of print roller squeeze
Pressure.In the case, which can be more much higher than in the case of pressure setting so far, without " excessively squeezing
Pressure" it is described printing figure.This has advantageously resisted groove impact or notch shock.Pass through the deformation of the ring
And the therefore adjusting of the diameter of the ring, it can not only realize matching of the printing equipment from different base material thickness, and
It can realize the matching with the printing plate of the different-thickness of base material to be printed, blanket or stereotype.
For two kinds it is favourable implement modification for it is common, can be with due to the damping element convertibly adjusted
The much higher extruding force of the printing cylinder is printed, and will not significantly affect the printing figure in the case.It is corresponding
The shock-sensitive degree (Sto β empfindlichkeit) of printing equipment be considerably reduced by adjustable damping element.
It is described of the invention and described of the invention be advantageously improved scheme also to be arbitrarily mutually combined display
Go out the present invention is advantageously improved scheme.
Favourable designing scheme in terms of the further advantage of the present invention and in terms of design aspect and function is in reference
With reference to the description of the description below and embodiment in the case of attached drawing.
Brief description of the drawings
The present invention should refer to attached drawing and be further elaborated on.Here, mutually corresponding element and component are equipped with the accompanying drawings
Identical reference numeral.For the sake of the more preferable general view of attached drawing, the view of actual proportions is given up.Show in the diagram
