Definitions
- the present invention relates to a composite sleeve with ceramic coating, intended to be etched on the surface in particular with a laser and used in flexographic printing machines for ink transfer.
- Sleeves made of composite material are already commonly used as a plate sleeve in flexographic printing machines. Such sleeves allow easy handling, rapid changes and above all make it possible to cover a very wide range of developments from the same carrying cylinder.
- This composite sleeve comprises at least one layer of material of the type comprising a complex composed of a layer of nonwoven material and of a layer of material having a high level of vacuum of the expanded type according to a determined geometry, the assembly being coated with a layer of resin having a strong shrinkage power determined during polymerization. Resin bridges provide the connections.
- the coating is rectified to give it a perfect round and then engraved, generally with a laser, to give it its capacity for retaining a given volume of ink per unit of area.
- This product is sophisticated and the cost price of such a cylinder is high.
- the cylinder must be changed or it is broken because the ceramic is resistant to wear but remains very fragile, the only way is to change the complete cylinder, which requires very long machine downtimes.
- mechanics that is to say the machining of rockets with rectified bearings, the bearings, accounts for 25% of the total price of the finished cylinder.
- a flexography machine can include three basic types of screen, which leads to 18 anilox cylinders for a six-color machine.
- the goal is therefore to offer anilox cylinders with a single support cylinder on which is mounted a ceramic sleeve on the surface and engraved, although the ceramic is very fragile and does not support any radial expansion and although the deposition of ceramic generates temperature rises very important.
- the composite sleeve adapted in particular to be mounted on a metal carrier cylinder and used for ink transfer, comprises a base sleeve which is radially deformable, a layer with limited deformability, an intermediate layer for absorbing radial deformations, and a layer of material with high heat dissipation capacity, ceramized.
- the base sleeve more particularly comprises at least one layer of complex type material composed of a layer of nonwoven material and of a layer of material having a high void content of the expanded type according to a determined geometry, the assembly being coated with a resin layer having a high shrinkage power determined during polymerization.
- the layer with limited deformability is made of fiberglass embedded in a hard resin capable of being rectified, forming a reinforcing belt.
- the intermediate layer for absorbing radial deformation comprises a triplex composed of an elastomer sandwiched between an internal layer of hard resin binding it to the layer with limited deformability and an external layer of hard resin binding it to the layer of material strong heat dissipation capacity.
- the elastomer has a hardness of approximately 60 shore and the resin has a hardness of 85 shore, the thickness of the intermediate layer being a few millimeters.
- the material of the layer with a high heat dissipation capacity is carbon or a polymer conductor embedded in a high glass transition point resin or metal alloy.
- the material of the layer with high heat dissipation capacity is directly coated with a ceramic coating, which is ground to the given diameter and etched.
- FIG. 1 a view of a preferred embodiment of an anilox cylinder according to the invention, with partial cutaway which show the different layers of material,
- FIG. 2 a view in longitudinal section of the anilox cylinder of FIG. 1
- the sleeve shown in Figure 1 comprises a base sleeve 10 to which is attached a layer 1 2 with radially limited deformability, an intermediate layer 14, compressible and a layer 1 6 with high heat dissipation capacity, capable of being coated with 'a layer 1 8 of ceramic material.
- the base sleeve 10 is of the type comprising at least one layer of low density material as described in European patent application No. 95 450009 in the names of the present applicants with resin impregnation to bond the layers together and make bridges in the radial direction, so as to leave a certain capacity for radial deformation by expansion under the effect of pressure to allow mounting on the carrier cylinder and a shrinking effect sufficient to prevent any rotation of the sleeve once the gas flow under interrupted pressure.
- This type of material comprises a layer of nonwoven material and a layer of material having a high voidness of the expanded type according to a determined geometry, the assembly being coated with a layer of resin having a high shrinkage power determined at polymerization. All of the constituents make it possible to achieve very low densities.
- the layer 1 2 with limited deformability is produced in the particular embodiment shown with glass fiber, arranged by filament winding or wrapping and impregnated with a very hard resin once polymerized.
- This layer forms a reinforcement belt.
- the intermediate layer 1 4 preferably comprises a triplex, that is to say a layer of a microcellular elastomer comprising open cell pores, sandwiched between two layers of very hard 85 shore resin.
- the hardness of the elastomer is rather situated in values from 50 to 60 shore.
- This type of elastomer thus sandwiched leads to very interesting deformation capacities as shown in FIGS. 3A and 3B. Indeed, the open cell foam compresses in perfectly radial directions without lateral deformation, that is to say parallel to the surface. There is no lateral creep under load.
- the resin which permeates this triplex also provides the connection between the layer with limited deformability and this triplex.
- This intermediate layer 14 is thin, of the order of a few millimeters, it is imperatively placed immediately under the layer 1 6 with high heat dissipation.
- the layer 1 6 with high heat dissipation is for example carbon or a conductive polymer embedded in a resin with a high glass transition point.
- This layer can also comprise a metal alloy based on aluminum or copper.
- This layer 1 6 is then directly coated with a projection of molten ceramic powder, in a plasma for example.
- the localized heat of the deposit is thus diffused in the support layer without degrading it.
- the composite sleeve is then rectified in a known manner with the diamond wheel to give it a regular outside diameter having a controlled particle size capable of undergoing etching by means of a laser.
- the structure of the sleeve according to the invention is such that the heat generated by the ceramic coating is dissipated without reaching either the base sleeve, the intermediate layer or the inner layer of the Triplex.
- the base sleeve When pressurized by the gas flow, it is the base sleeve which compresses to gain the few hundredths of a millimeter of radial expansion necessary for assembly.
- the layer 1 2 with limited deformability prevents the spread of radial expansion. If radial expansions were to subsist and propagate, the intermediate layer is there to absorb this expansion, certainly preventing any transfer of expansion to the layer with high heat dissipation capacity coated with ceramic.
- the air flow is interrupted and the base sleeve encloses the carrier cylinder and immobilizes said sleeve on said cylinder.
- the deformable intermediate layer is transferred to the outside of the sleeve, which at the same time limits the shearing effects between the different coaxial layers.
- microporous elastomers have low shear strengths and the more they are in the center, the less material there is to absorb the forces generated by the rotation of the carrier cylinder and its sleeve.
