Description
Technical field
The utility model relates to the technical field of intaglio press, discloses especially a kind of intaglio press unreeling structure and comprises its intaglio machine for web-fed printing.
Background technology
Intaglio press is to adopt circle to press the direct mode of printing printing of circle, adopts and soaks China ink or ink-jetting style to China ink, and forme is directly on plate cylinder.Intaglio press is mainly made up of several parts such as unreeling machine, uncoiling traction, print couple, rolling tractions.Unreeling machine has been mainly the expansion of material film under certain speed and tension force condition, and keeps corresponding stable state, completes the automatic or manual splicing of roll web simultaneously.The major function of traction is to ensure that in printing process, unreeling printing element material film does not produce skew, ensures the tension stability of paper simultaneously.Print couple is the chief component of intaglio press, completes the main process of printing, comprises ink supply, printing, oven dry etc.Rolling traction principal security printing element, to the tension stability of rolling, improves print quality.Rolling completes the process of printing, and the stable of winding tension can ensure rolling effect.
Along with the development of intaglio printing, intaglio press is constantly upgrading improvement also.For example, patent CN101348027A discloses a kind of satellite type intaglio printing machine, and its utilization has two and above roller in the circle distribution of pressure roller, is equivalent to many traditional printing machines in work, has increased the efficiency of printing.Patent CN103568479A discloses a kind of intaglio machine for web-fed printing, comprise two above printing equipments, shared one is set on the unwinding device and the wrap-up that is arranged on described another side of printing equipment of described printing equipment side, thereby it is simple in structure to realize it, be convenient to safeguard, can improve printing efficiency, reduce enterprise's production cost.
In fact, running up in process of intaglio press, stable tension force plays vital effect to chromatography precision.Generally speaking, cause tension fluctuation because have: (1) printing substrate is rolled up not around even, eccentric; (2) depth of parallelism between deflector roll is bad; (3) tension-detecting mechanism or tension force control assembly break down; (4) paper skids and causes tension fluctuation; (5) intaglio press tension force in ascending, descending speed process also there will be fluctuation; (6) substrate thickness is inhomogeneous.But the research improving for the tension force of intaglio press in prior art is less, particularly very rare by improve to improve the technical scheme of tension force control stability for the unwinding unit of intaglio press.Patent CN103569714A discloses a kind of feeding machanism of intaglio press, and it,, by tension pick-up and deviation correcting device are set, can ensure feed continous-stable, has reduced the percent defective of printing.This patented technology is adjusted the distribution of tension force in time by deviation correcting device, do not accomplish yet to prevent, and equipment investment cost is high in advance.
Utility model content
The purpose of this utility model is to provide a kind of intaglio press unreeling structure, it sets up dancing roll after unreeling machine, thereby increase paper enters the cornerite of jockey pulley, the friction that improves paper and jockey pulley, avoid paper to skid and cause tension fluctuation, thereby improve the precision and stability of chromatography.
Another object of the present utility model is to provide a kind of intaglio machine for web-fed printing; it sets up dancing roll between unreeling machine and jockey pulley; avoid paper to skid on the one hand and cause tension fluctuation, also improve on the other hand not shut down automatically connecing connecting material and interference and the fluctuation of fracture to system tension stability in the process of reloading.

Wherein, cornerite refers to paper and the right central angle of roll shaft contact arc, the size of cornerite, and the length of reflection band and belt wheel wheel circular surfaces Contact arc, has also determined the position that dancing roll is set indirectly.For improving the frictional force of paper transmission, to avoid paper to skid and cause tension fluctuation, cornerite just can not be too little.
Preferably, dancing roll is fixed on splicing knife rest by bearing, can save on the one hand the installing space of dancing roll, the cornerite control of being convenient on the other hand not shut down the paper automatically connecing in the process of reloading and entering dancing roll, jockey pulley.
Preferably, dancing roll is provided with tension pick-up and deviation correcting device, by the tension condition of tension pick-up real-time monitoring system, trigger deviation correcting device when there is tension force larger fluctuation, with adjust dancing roll up and down or position, left and right, thereby change the cornerite of paper contact jockey pulley, jockey pulley, the stable tension level of recovery system in time, ensure the continous-stable of paper feeding, reduce the percent defective of printing.
A kind of intaglio machine for web-fed printing that the utility model provides, comprises unwinder unit, uncoiling traction unit, print couple, rolling traction unit, and wherein uncoiling traction unit comprises jockey pulley, and unwinder unit is above-mentioned intaglio press unreeling structure.
Preferably, for improving the production efficiency of intaglio press, described print couple comprises two above printing units.Many printing machine units share identical unreeling structure and rolling traction unit, can improve printing efficiency, reduce production costs.
The beneficial effects of the utility model have:
1, intaglio machine for web-fed printing of the present utility model, it sets up dancing roll between unreeling machine and jockey pulley, can avoid paper to skid and cause tension fluctuation; Improve again not shut down and automatically connect connecting material and interference and the fluctuation of fracture to system tension stability in the process of reloading; While also significantly having improved upper volume, change of lap, roll shaft rotates the paper scratch phenomenons such as the gold card, silver card and the holographic transfer paper that cause.
