Description
Technical field
The present invention relates to printing technologies, and in particular to a kind of printing equipment of warpage cardboard and its printing process.
Background technique
Carton is widely used in packaging industry, the manufacturing process of carton include prepare cardboard, cardboard cutting, molding,
The processes such as printing, printing process, which refers to, sprays one layer of text or pattern ink on the surface of cardboard, enriches its appearance.It is existing
The printing machine of technology is easy to appear printing surface void side phenomenon as shown in Figure 1 and paper jam phenomenon shown in Fig. 2, and there are biggish
Defect.
Summary of the invention
In view of the above problems, the present invention provides printing equipment and its printing process of a kind of warpage cardboard, can be suitable for
The printing of warpage cardboard, and printing surface void Bian Xianxiang and paper jam phenomenon can be improved.
To achieve the above object, the present invention solves by the following technical programs:
A kind of printing equipment of warpage cardboard, including set gradually conveying mould group, printing die group, paper feeding mould group, correct mould group,
The conveying mould group is equipped with distance measuring sensor, and the printing die group includes upper roller and is located at immediately below the upper roller
And the lower roller opposite with the upper roller rotation direction, the upper roller lateral surface are equipped with printing pattern layer, the first foam-rubber cushion
Layer, the lateral surface of the lower roller are equipped with the second sponge bed course, third sponge bed course, the first sponge bed course, the second sponge bed course,
The surface of third sponge bed course is coated with low viscosity material, and the viscosity of the first sponge mat surface is less than second sea
The viscosity of continuous mat surface, the viscosity of the first sponge mat surface are greater than the viscosity of the third sponge mat surface, institute
State the first sponge bed course and be located at the printing pattern layer side, the correction mould group include several cylinders being arranged successively and
It is connected to the mounting rack of each cylinder output shaft lower end and upper roller, bottom roller with mounting rack rotation connection.
Specifically, the conveying mould group is made of several conveying rolls.
Specifically, the paper feeding mould group includes the first feed roller group, the second feed roller group, the rolling of the first feed roller group
Idler wheel outer diameter of the outer diameter less than the second feed roller group is taken turns, the first feed roller group is close to the setting of printing die group side.
Specifically, being additionally provided with ink roller cylinder on the upside of the upper roller.
Specifically, the second sponge bed course and the third sponge bed course are located at the same center of circle of the lower roller section
On line.
A kind of printing process of warpage cardboard, applies the printing equipment of the warpage cardboard, comprising the following steps:
S1 cardboard is delivered on the downside of distance measuring sensor by conveying mould group, itself and cardboard upper surface are persistently measured by distance measuring sensor
Height h, obtain a series of time t1、t2…tnAnd corresponding height number h1、h2…hn, record data to control system
In system；
S2 control system is with a series of time t1、t2…tnAnd corresponding height number h1、h2…hnDepict corresponding song
Line, and the mirror curve of the curve is simulated, by the shape of mirror curve, make multiple upper rollings using the height adjustment of cylinder
Midpoint between wheel and bottom roller meets the shape of mirror curve；
If S3 control system judges h0.5n-1< h0.5n> h0.5n+1, then determine that the cardboard is positive and put cardboard；If control system is sentenced
Disconnected h out0.5n-1> h0.5n< h0.5n+1, then the cardboard is determined to be buckled to cardboard；
For S41 when cardboard is positive and puts cardboard, lower roller turns to the second sponge bed course immediately below the first sponge bed course, and just
Put cardboard by the first sponge bed course, the second sponge bed course drive under enter between upper roller, lower roller, utilize printed patterns
Layer imprints out pattern just putting on board side；
S42 is just putting cardboard due to the characteristic of its shape, leaves and has upturned trend between upper roller, lower roller, due to
The sticky viscosity less than the second sponge mat surface of first sponge mat surface, so that just putting when cardboard is detached from certain
Downward viscous drag, thus reduce just putting amplitude upturned when cardboard leaves between upper roller, lower roller, and smoothly into
Enter in paper feeding mould group；
S43 is just putting cardboard by correcting mould group, and due to by the roller pressure opposite with its warp direction, when discharging becomes straight；
For S51 when cardboard is back-off cardboard, lower roller turns to third sponge bed course immediately below the first sponge bed course, and just
Put cardboard by the first sponge bed course, third sponge bed course drive under enter between upper roller, lower roller, utilize printed patterns
Layer imprints out pattern on back-off board side；
S52 is buckled to cardboard due to the characteristic of its shape, leaves the trend that downsagging is had between upper roller, lower roller, due to
The viscosity of first sponge mat surface is greater than the viscosity of third sponge mat surface, so that just putting when cardboard is detached from certain
Upward viscous drag, to reduce the amplitude of back-off cardboard downsagging when leaving between upper roller, lower roller, and smoothly into
Enter in paper feeding mould group；
S53 is buckled to cardboard by correcting mould group, and due to by the roller pressure opposite with its warp direction, when discharging becomes straight.
The beneficial effects of the present invention are:
The first, a kind of printing equipment of warpage cardboard of the invention and its printing process, increasing before printing pattern layer can
Sponge with paper, sponge drive cardboard edge to enter, avoid the occurrence of the printing surface void Bian Xianxiang of cardboard, and increase in lower roller
The inconsistent sponge of two surface viscosities, using the viscosity differences of itself and upper roller sponge, finally enable cardboard smoothly into
Enter in paper feeding mould group, prevents paper jam；
The second, it increases distance measuring sensor and corrects mould group, correct mould group by multiple cylinders arranged in a uniform, upper roller, lower rolling
Wheel composition, the upper surface curve shape of cardboard is first detected using distance measuring sensor, then simulates mirror curve by system, benefit
Make the midpoint between multiple upper rollers and bottom roller meet the shape of mirror curve with the height adjustment of cylinder, passes through cardboard
Mould group is corrected by the roller pressure opposite with its warp direction, when discharging becomes straight.
