Abstract

A silica gel embossing roller comprises a roller body and a roller surface, characterized in that the roller surface is a silica gel layer having embossing, and a middle connecting layer is arranged between the roller body and the roller surface layer. The silica gel embossing roller of the utility model can press leatheroid which has quite high simulation degree, good hand touch and luminosity, and has no use for disposing. And moreover, the utility model has longer utilizing life.

Description

Silica-gel embossing roller

(1) technical field

The utility model relates to a kind of embossing instrument of artificial leather surface pattern press forming, more particularly, relates to a kind of Silica-gel embossing roller.

(2) background technology

Artificial leather or other machining object through surperficial embossing, can form the lines of various floral designs or imitative animal and plant in its surface.Artificial leather through handling like this can promote the value and the market of manufacture.Therefore, this technology widely adopts in the art.At present, the general embossing instrument that adopts has two kinds: release liners and steel line roller.

1. release liners

Solution is coated on the pending surface of artificial leather, had the release liners of lines face on fitting then, peel off release liners again after heating, cooling, the artificial leather surface just forms the decorative pattern that requires.The release liners of using in this method not only costs an arm and a leg, and service life is shorter, so cost is higher.

2. steel line roller

At first steel line roller is placed on the appropriate location of embossing machine,, again the artificial leather without embossing is fed tooled joint between steel line roller and the rubber rollers at leisure then with embossing machine and without the heating of the artificial leather of embossing.Through embossing, the artificial leather surface just forms the decorative pattern that requires.The shortcoming of this method maximum is that fidelity is not high.Therefore, can not meet the demands.

(3) utility model content

The purpose of this utility model is to provide a kind of not only can suppress the high artificial leather of fidelity, and service life is than long Silica-gel embossing roller.

Silica-gel embossing roller of the present utility model comprises the body of roll and roll surface, is characterized in, described roll surface is the layer of silica gel that one deck has embossing, is provided with one deck intermediate connecting layer between the described body of roll and the described roll surface layer.

Adopt Silica-gel embossing roller of the present utility model, can be the decorative pattern that the user provides more renewals, make product superior, thereby promote the value and the market of commodity.Because the embossing fidelity height that suppresses is so the lines strong sense of reality.In addition, when adopting Silica-gel embossing roller embossing of the present utility model, need not to handle and luminosity is arranged, good hand touch, effect is good.

For further specifying above-mentioned purpose of the present utility model, design feature and effect, the utility model is described in detail below with reference to accompanying drawing.

(4) description of drawings

Fig. 1 is the vertical section schematic diagram of the utility model Silica-gel embossing roller;

Fig. 2 is the A-A cross section cut-away view among Fig. 1.

(5) specific embodiment

See figures.1.and.2, the utility model Silica-gel embossing roller 1 comprises the body of roll and roll surface, and the wherein said body of roll 2 is a steel rider.Be provided with the water cooling passageway (not shown) in the steel rider.Water cooling mode generally is divided into two kinds: unidirectional water flowing and two-way water flowing.Described roll surface is the layer of silica gel 3 that one deck has embossing, and is provided with one deck intermediate connecting layer 4 between the described body of roll 2 and the described roll surface layer of silica gel 3.A kind of like this articulamentum 4 also is a layer of silica gel.

Silica-gel embossing roller of the present utility model is made by following steps:

1. the packing element cover is made

(1) patterned template that provides according to the client is at first flattened this model cleaning, then silica gel is coated on the model equably.After treating that silica gel solidifies, both are separated, promptly leave the lines on the model on the silica gel surface.In this manner, copy polylith silica gel sheet again.Examine lines,, and then also synthesize the silica gel line pipe of a circle by seam with moving towards of lines above-mentioned two or polylith silica gel sheet and synthetic a bulk of.

(2) then, with the silica gel line pipe of above-mentioned gained, with the lines one side in being built in a cylinder and its outer surface and cylinder wall are close to.Then, make the cylinder rotation,, continue again to roll, until epoxy resin cure again with in the epoxy resin injecting tube.Take out the epoxy resin roller and peel off silica gel line pipe.At this moment, on the epoxy resin roll surface, present the lines the same with model.

(3) utilize the epoxy resin roller that makes in above-mentioned (2) step, make its horizontal on rotating fulcrum, rotate on one side, be coated with equably on one side and apply silica gel, solidify until silica gel.Peel from the epoxy resin roller, be the silica gel jacket casing that does not have and stitch (being called for short the packing element cover) that requirement is made.

2. Silica-gel embossing roller is made

With made packing element cover in above-mentioned 1. (3) steps, outwards place cylinder and the textured surface and the drum inner surface of packing element cover are close to lines, simultaneously treated steel rider is placed on the center of cylinder, so that the annular gap equalization between packing element cover and the steel rider.After treating fixing and finding time, just silica gel can be injected in the above-mentioned annular gap until being full of.Leave standstill fully and solidify.Take cylinder apart, take out the Silica-gel embossing roller of making.The length of the Silica-gel embossing roller of making through above-mentioned steps is 1370 millimeters to 1700 millimeters, and its diameter is 220 millimeters to 275 millimeters.The thickness of embossing layer of silica gel is the 1.0-5.0 millimeter.

Silica-gel embossing roller device of the present utility model on embossing machine, just can be carried out surperficial embossing to artificial leather or other machining object.Simultaneously, produce artificial leather or other machining object that the surface has the desired lines of client.

Certainly, those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in the scope of the utility model claims variation, the modification of the above embodiment.
