Abstract

The utility model relates to the technical field of encapsulated roller, in particular to an encapsulated roller, comprising a cylindrical steel structural element barrel clay body and film or cloth wrapped on the surface of the clay body. The film or cloth wraps from layer to layer on the surface the clay body, forming an elastic material layer. The encapsulated roller of the utility model resolves the question that the prior encapsulation for rollers with large diameter is difficult to maintain with high maintaining cost.

Description

A kind of encapsulate running roller

Technical field:

The utility model relates to roller encapsulation techniques field, refers in particular to a kind of encapsulate running roller.

Background technology:

Known from institute, center impression roller in the central cylinder type press is the emphasis of machine, particularly in the satellite-type intaglio press, center type impression wheel outside will coat one deck elastic material in order to impression, but, because center impression roller general diameter is very big, as the six-color printing press general diameter about 3m, and traditional drum rubber is finished by the rubber-covered roll factory, heat through high temperature again after being wound in rubber on the cylindrical shell, sulfuration forms, and rubber invests cylinder surface after being melt into one, and it is smooth rubber surface to be polished flat at last again, its complex process, cost is higher, and the rubber-covered roll factory more than the present domestic energy preparation size diameter 3m and few, has limited the development and the application of large scale rubber roll, if machine in use on the other hand, when going wrong, impression wheel must be pulled down and change or encapsulate, so a big wheel again as the encapsulate layer, dismounting and transportation all are pretty troublesome things concerning the user.

The utility model content:

For addressing the above problem, the utility model provides a kind of wound form encapsulate running roller simple, that cost is low of making and safeguard.

For achieving the above object, the utility model is achieved through the following technical solutions: it comprises cylindrical steel structural member cylinder base substrate and is wrapped in the film or the cloth of billet surface that the surface that described film or cloth successively are wound in base substrate forms an elastic material layer.

The utility model is that film (as TPU film or cloth) in layer is wrapped on the drum surface of center impression roller, form the elastic material of the similar encapsulate of one deck, replace rubber-wrapping structure with this, it can directly be applied on the roller that does not coat encapsulate, also can be applicable on the roller that uses rubber-wrapping structure, and will not remove by roller, only need film or the encapsulate that twine on the surface are divested, again twining upper film again gets final product, it is difficult in maintenance to have solved present major diameter roller encapsulate, the difficult problem that maintenance cost is high.

Description of drawings:

Accompanying drawing 1 is a structural representation of the present utility model

Accompanying drawing 2 is the structural representation of stretch wrap film layer on printing machine

The specific embodiment:

See accompanying drawing 1, present embodiment comprises center impression roller, film or cloth, the impression roller surface is wound with plural layers 50 (as the TPU film) or cloth at described center, the elastic material layer that film or cloth form a similar encapsulate is coated on center impression roller surface, replaces traditional rubber-wrapping structure with this.Particularly in the satellite-type intaglio press, center type impression wheel is outside to need to coat one deck elastic material in order to impression, adopts structure of the present utility model, does not need that then the center is impressed roller and disassemble when maintenance update encapsulate elastic material, removes the many troubles of storage from.

The utility model can be applicable on the central cylinder type press, and heart impression roller surface is twined upper film or cloth layer by layer therein, forms one deck elastic material and is beneficial to impression.Embodiment sees accompanying drawing 2, the frame of described central cylinder type press is provided with one or more groups printing equipment 20 that is looped around center impression roller 30 outer rims, anilox roll 22 will be replaced by on the printing equipment 20, anilox roll 22 and the pressing mutually of center impression roller 30, film or cloth are exported after each guide wheel is transported to center impression roller 30 and anilox roll 22 pressings from unwinding device 12, when anilox roll 22 and center impression roller 30 pressings, glue on the anilox roll 22 is just transferred to film surface under pressure, makes film surface coat glue equably.When power set 21 drove film or cloth rotation, film just was wrapped in impression roller 30 surfaces, center layer by layer.The elasticity of film and anti-dissolubility can be selected with requiring according to actual needs; the number of turns that film twines also is to decide as required; when the number of plies of twining arrives predetermined number; be that film has arrived preset thickness, shut down the film tail end is handled the smooth coating work of promptly finishing center impression roller 30.

The utility model also can be applicable to and is using on the center impression roller of rubber-wrapping structure, as the satellite-type intaglio press, center impression roller has been installed on the printing machine, go wrong as encapsulate, not needing that the center is impressed roller disassembles and can repair its surperficial elastic material, the old glue-line that only needs the center to be impressed roller surface divests, clean out, version roller with printing machine is changed to anilox roll then, in the pigment groove, inject glue and can impress the roller surface stretch wrap film, form one deck elastic material at the center.

It only is preferred embodiment of the present utility model that above institute is chatted, and does not therefore limit protection domain of the present utility model.

Claims

1, a kind of encapsulate running roller is characterized in that: it comprises cylindrical steel structural member cylinder base substrate and is wrapped in the film or the cloth of billet surface that the surface that described film or cloth successively are wound in base substrate forms an elastic material layer.
