Fig. 4 is the figure that the operation principle of rotary screen-printing machine in the present invention is described with chart.
Lift an example, above-mentioned rotary screen-printing layer (150) likely utilizes 1 above rotary screen-printing machine to form.
Above-mentioned rotary screen-printing refers to: ink is poured into behind the silk screen inside of the drum that forms pattern, by the net forming, discharged ink on silk screen, copy continuously the mode of texture.
With reference to Fig. 4, silk screen (screen, the F) inside on rotating print machine (rotaty press, H), arranges rubber roll shaft (squeege, E).Steel plate (A) allows silk screen (F) and backer roll (impression roller below above-mentioned silk screen, G) between, with certain speed, carry out work, when above-mentioned steel plate (A) passes through rotary screen-printing machine, according to the translational speed of steel plate (A), silk screen (F) also can be according to certain speed rotation.At this moment, the rubber roll shaft (E) on rotary press (H) is the place crossing together at silk screen (F), steel plate (A) and backer roll (G), by its angle youngster, is fixed its position.
Next, ink (ink, D) can automatically be fed to the central authorities of silk screen (F), be gathered on the major opposing side (leadingside) of rubber roll shaft (E) and wedge shape (wedge-shaped) wall (well) of silk screen inner surface formation.The athletic meeting of silk screen (F) launches ink (D), even if do not have (flood bar) also to gush out from silk screen (F), to masterplate (stencil, B) gap, provides ink.Afterwards, rubber roll shaft (E) can block ink, so can be stained with one deck ink on steel plate.(ink?deposit,C)
Conventionally, rotary screen-printing mode is always usually for other field, for example, and manufacture of interior decoration wallpaper and flooring material etc.But, when being applicable to the color steel sheet of the continuous mode of production and manufacturing, because the distortion of the materials such as WAVE distortion and arc occurs the characteristic of steel plate materials, so be difficult to carry out stably printing treatment.Therefore, up to the present, think: can not produce the color steel sheet that presents space pattern on steel plate by rotary screen-printing mode always.
While adopting above-mentioned rotary screen-printing mode to manufacture steel plate, because of amplitude direction thickness deviation (20～30 μ m) and the bad problem such as sporadic inhomogeneous superficial phenomenon (WAVE) and arc (camber) existing in original steel plate materials, between the contact interface of material and above-mentioned rotary printing machines (H), can produce a part of gap, and the ink transfer that will form space pattern in this gap must have some setbacks, be therefore difficult to carry out stable and consistent printing treatment.
And, the variation of the centre contact-making surface position that the bad problem of printing that the speed difference of steel plate and rotary printing machines (H) causes and the elasticity of backer roll diameter and each thickness of steel plate materials cause, the contact-making surface that makes it rotary printing machines (H) broadens, and is therefore difficult to present subtly on steel plate expected decorative pattern and pattern.
To this, according to an example, above-mentioned rotary screen-printing machine is likely to comprise rotary printing machines (H) and the backer roll (G) that contains squeegee (E) and silk screen, may comprise again tension level(l)er (Tension Leveller), also likely before and after above-mentioned rotary screen-printing machine, possess idler roller (Tension Bridle Roll).
In the foremost position of above-mentioned rotary screen-printing machine, direction with steel plate amplitude, above-mentioned tension level(l)er and above-mentioned idler roller (Tension Bridle Roll) are installed, are reduced to greatest extent the distortion of steel plate materials, with this, can prevent from printing bad phenomenon.
On the one hand, because the rotating speed of steel plate and above-mentioned rotary printing machines (H) is variant, so may print bad problem.If the rotary speed of above-mentioned rotary printing machines (H) than steel plate to carry out speed fast, likely can not form the thickness that pattern is expected; On the contrary, if the rotary speed of above-mentioned rotary printing machines (H) than steel plate to carry out speed slow, the effect that the texture printing may have ghost image or be stretched out.
This problem, can be resolved by controlling the method that speed is consistent of carrying out of the rotary speed of above-mentioned rotary printing machines (H) and steel plate.
And, variation for printing contact-making surface centre position, by grasping the centre printing points (point) of each thickness steel plate, rotary printing machines (H) is designed to by above-below direction removable, centre printing points at this moment can change because of the elasticity of steel plate.But, by this design, can carry out stable printing treatment, and then can also produce careful and there is relief color steel sheet.

In an example, each distance that above-mentioned rotary screen-printing machine is arranged between it and above-mentioned top and bottom deflection roll is approximately on the position of 3:1, according to the image of pattern and/or measure of precision, above-mentioned top deflection roll is adjusted to fore-and-aft direction to be moved, with this, determine suitable position, the change in location of different-thickness material plate of take is afterwards basis, determines the position of centre printing contact-making surface.
For example, along with the fore-and-aft direction position of above-mentioned top deflection roll changes, the value of the centre contact angle forming at contact-making surface and above-mentioned backer roll also can change equally.Now, consider the centre position of the above-mentioned rotary screen-printing machine having changed, the position of above-mentioned rotary screen-printing machine is moved up and down changeably, allow it just contact with centre, thereby can stablize and print meticulously.
Now, place before above-mentioned rotary screen-printing power traction enters, in order to control the tension force of the material plate changing according to the movement of above-mentioned backer roll, and offset to greatest extent the arc of material plate, between above-mentioned bottom deflection roll and above-mentioned rotary printing machines (H), stabilizing roller (Stabilize Roll) can be installed in addition again.
According to foregoing, above-mentioned rotary screen-printing machine is to consider production line structure, in vertical (Vertical) mode, application is installed, but not limited thereto; If production line space is restriction not, also can application level (Horizontal) mode.
Above-mentioned horizontal mode if, can uneasy load the stabilizing roller of tension stability and arc negative function as the case may be.And at this moment, use fixed backer roll, change rotary silk screen position into moving forward and backward mode.
