Description
Technical field
The utility model belongs to plate-making technology field, relates to a kind of hollow roller, particularly the hollow roller of a kind of three-layer type.
Background technology
Intaglio printing is the one of typography, has layer of ink abundant, bright in luster, saturation degree is high, printing quality is high and stable, print speed printing speed fast, truly can reduce the advantages such as original copy effect.Abroad, gravure is used for the meticulous publications such as magazine, is also applied to the fields such as banknote, packages printing, ornament materials.At home, gravure is mainly used in flexible package, sheet package, graining, leather substance etc.Along with water base gravure ink research and development and widely use, intaglio printing has become a kind of important printing technology meeting environmental requirement, is applied to increasing print field.
The topmost parts of intaglio printing are roller, by carving in roller or eroding away corresponding pattern, reach the effect of trans-printing.And roller of the prior art adopts solid steel rider to add mostly, and roll shaft processes, for some large-scale printed articleses, need the roller making large-size, now adopt solid steel rider that roller weight then can be caused excessive, cause cost higher on the one hand, also high to the power demand of printing machine when printing on the other hand, and transport is also very inconvenient.
Utility model content
The purpose of this utility model there are the problems referred to above for existing technology, proposes the hollow roller of the high three-layer type of a kind of structural strength.
The purpose of this utility model realizes by following technical proposal: the hollow roller of a kind of three-layer type, it is characterized in that, comprise in hollow outer roller and the roll shaft being arranged at outer roller two ends, described outer roller two ends are provided with the end cap be connected with roll shaft, the central shaft through interior roller is also provided with between described roll shaft two ends, interior roller is also provided with between described outer roller and central shaft, also be provided with the support unit be supported between interior roller outer wall and outer roller inwall outside described interior roller, described interior roller two ends are also provided with the terminal pad for interior roller and outer roller being connected.
In the hollow roller of above-mentioned three-layer type, described roll shaft center is also provided with Cooling Holes, and the end that described roll shaft stretches into inside outer roller is also provided with apopore, and described Cooling Holes communicates with apopore.Inject cooling water by the Cooling Holes at roll shaft center, and flow between outer roller and interior roller by apopore, cooling effect can be carried out to roller.
In the hollow roller of above-mentioned three-layer type, described central shaft is hollow form, and described central shaft two ends are threaded with roll shaft, and described apopore communicates with in the middle part of central shaft.By the effect of this central shaft, also can be used as water stream channel, the cooling medium in the roll shaft of side is entered in opposite side roll shaft by central shaft.
In the hollow roller of above-mentioned three-layer type, described terminal pad is provided with several water holes arranged ringwise.The effect of terminal pad is that internal roller and outer roller are connected, and the effect that terminal pad is offered water hole is, when outer roller needs to cool, need in outer roller, to inject cooling fluid by roll shaft, now cooling fluid is entered between interior roller and outer roller by water hole.
In the hollow roller of above-mentioned three-layer type, described support unit is uniformly distributed in interior roller outer wall along interior roller axial direction.Make to be connected firmly between interior roller and outer roller by support unit, when preventing outer roller high-speed rotation, interior roller assembling is loosely broken down.
In the hollow roller of above-mentioned three-layer type, described support unit is several annular spread in the support bar of interior roller outer wall and outer roller inwall.Strong point circumference can be made to be uniformly distributed in interior roller outer wall by the support bar of annular spread.
Compared with prior art, the hollow roller of this three-layer type is by arranging support unit between interior roller and outer roller, improve the structural strength of roller, Cooling Holes and apopore are set on roll shaft simultaneously, and cooling water is set in central shaft, conveniently cool roll body, it is simple that it has structure, lightweight, the advantage that structural strength is high.

Detailed description of the invention
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figure 1 to Figure 2, the hollow roller of this three-layer type comprises in hollow outer roller 1 and the roll shaft 2 being arranged at outer roller 1 two ends, outer roller 1 two ends are provided with the end cap 4 be connected with roll shaft 2, the central shaft 7 through interior roller 3 is also provided with between roll shaft 2 two ends, interior roller 3 is also provided with between outer roller 1 and central shaft 7, also be provided with the support unit be supported between interior roller 3 outer wall and outer roller 1 inwall outside interior roller 3, interior roller 3 two ends are also provided with the terminal pad 5 for interior roller 3 and outer roller 1 being connected.Roll shaft 2 center is also provided with Cooling Holes 22, and the end that roll shaft 2 stretches into inside outer roller 1 is also provided with apopore 21, and Cooling Holes 22 communicates with apopore 21.Inject cooling water by the Cooling Holes 22 at roll shaft 2 center, and flow between outer roller 1 and interior roller 3 by apopore 21, cooling effect can be carried out to roller.Central shaft 7 is in hollow form, and central shaft 7 two ends are threaded with roll shaft 2, and apopore 21 communicates with in the middle part of central shaft 7.By the effect of this central shaft 7, also can be used as water stream channel, the cooling medium in side roll shaft 2 is entered in opposite side roll shaft 2 by central shaft 7.
