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 two-layer equation.
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 two-layer equation of a kind of structural strength.
The purpose of this utility model realizes by following technical proposal: the hollow roller of a kind of two-layer equation, comprise in hollow outer roller and the roll shaft being arranged in outer roller center, described outer roller two ends are provided with the end cap be connected with roll shaft, described outer roller inside be also provided with concentric with outer roller in roller, described roll shaft is fixedly connected with interior roller, it is characterized in that, 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 two-layer equation, 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 two-layer equation, 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.
In the hollow roller of above-mentioned two-layer equation, 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 two-layer equation, 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 two-layer equation, described apopore is two and lays respectively to be oppositely arranged.
Compared with prior art, the hollow roller of this two-layer equation, by arranging support unit between interior roller and outer roller, improves the structural strength of roller, on roll shaft, arrange Cooling Holes and apopore, conveniently cool roll body, it is simple that it has structure simultaneously, 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 3, the hollow roller of this two-layer equation comprises in hollow outer roller 1 and the roll shaft 2 being arranged in outer roller 1 center, outer roller 1 two ends are provided with the end cap 4 be connected with roll shaft 2, outer roller 1 inside be also provided with concentric with outer roller 1 in roller 3, roll shaft 2 is fixedly connected with interior roller 3, 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.Support unit is uniformly distributed in interior roller 3 outer wall along interior roller 3 axle 2 to direction, and support unit is several annular spread in the support bar 6 of interior roller 3 outer wall and outer roller 1 inwall.Make to be connected firmly between interior roller 3 and outer roller 1 by support unit, when preventing outer roller 1 high-speed rotation, interior roller 3 assembles and loosely breaks down.Strong point circumference can be made to be uniformly distributed in interior roller 3 outer wall by the support bar 6 of annular spread.
For convenience of the cooling of roller, this roller is also provided with cooling system, this cooling system comprises the Cooling Holes 22 that is arranged at roll shaft 2 center and is arranged at the apopore 21 that roll shaft 2 stretches into outer roller 1 side, described Cooling Holes 22 communicates with apopore 21, in addition, described terminal pad 5 is also provided with the water hole 51 that several are arranged ringwise.The effect of terminal pad 5 is that internal roller 3 and outer roller 1 are connected, when roller needs to cool, in outer roller 1, inject cooling fluid by roll shaft 2, now cooling fluid enters outer roller 1 by Cooling Holes 22 along apopore 21, and enters between interior roller 3 and outer roller 1 along water hole 51.For convenience of the outflow of cooling water, described apopore 21 is two and lays respectively to be oppositely arranged.
The hollow roller of this two-layer equation, by arranging support unit between interior roller 3 and outer roller 1, improves the structural strength of roller, arranges Cooling Holes 22 and apopore 21 on roll shaft 2 simultaneously, conveniently roll body is cooled, it is simple that it has structure, lightweight, the advantage that structural strength is high.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
