Abstract

The utility model discloses a separator roll, in particular a separator roll which is arranged on a fabric rolling machine and is used for avoiding crease generated in the fabric rolling process. The separator roll comprises a roller, wherein a roll shaft is fixed in the roller. The separator roll is characterized in that the roller is a metal hollow drum; spiral convex ribs are arranged on the external surface of the metal hollow drum and are formed by extruding the metal hollow drum in a cold extruding mode; the spiral convex ribs are formed by expanding spirally towards two ends from the axial middle of the metal hollow drum respectively in reverse. The separator roll has the advantages that the process can be simplified, the production cost is reduced, and the separator roll is suitable for industries such as textile industry and printing industry.

Description

A kind of minute roll dies

Technical field

The utility model relates to a kind of minute roll dies, specifically, is mounted on fabric clot equipment, avoids occurring minute roll dies of gauffer in the fabric wrapping process.Be applicable to the industries such as weaving, printing and dyeing.

Background technology

At present, in industries such as weaving, printing and dyeing, be used for avoiding occurring that minute roll dies of gauffer is all tradition minute roll dies in the fabric wrapping process.This tradition divides roll dies to comprise roller, in roller, is fixed with roll shaft.Described roller is the empty cylinder of metal, is provided with the spiral fashion convex tendon on the outside face of the empty cylinder of metal, and this spiral fashion convex tendon is to adopt welded wire on the outside face of the empty cylinder of metal and form.Although adopt this minute roll dies can avoid gauffer occurring in the fabric wrapping process, because the spiral fashion convex tendon on the empty tube outer surface of metal is to adopt welded wire to form, make production stage many, complex process.Because the spiral fashion convex tendon on the empty tube outer surface of metal is to adopt welded wire to form, material requested is more again, and productive costs is high.In addition, because the spiral fashion convex tendon on the empty tube outer surface of metal is to adopt welded wire to form, the time one is long, and weld nugget is easy to wear, makes metal filament easily come off, and service life is not long.

The utility model content

Problem to be solved in the utility model is to provide a kind of minute roll dies.Adopt this minute roll dies, can simplify technique, reduce production costs.

For addressing the above problem, take following technical scheme:

Roll dies comprised roller in of the present utility model minute, in roller, was fixed with roll shaft.Be characterized in that described roller is the empty cylinder of metal, has the spiral fashion convex tendon on the outside face of the empty cylinder of metal.Described spiral fashion convex tendon is to adopt the cold extruding mode empty cylinder extruding forms to metal, and described spiral fashion convex tendon starts to be respectively oppositely from the axial centre of the empty cylinder of metal and forms to its two ends spiral extension.

Wherein, described roller is corrosion-resistant steel roller or aluminum alloy roller.

Take such scheme, have the following advantages:

As can be seen from the above scheme, because described spiral fashion convex tendon is to adopt the cold extruding mode to push and form the empty cylinder of metal.With background technology, compare, need be at the empty tube outer surface welded wire of metal, not only processing step is few, and technique is simple, and has saved metal filament, has reduced productive costs.Again because described spiral fashion convex tendon is to adopt the cold extruding mode to push and form the empty cylinder of metal, make the empty cylinder of spiral fashion convex tendon and metal be structure as a whole, with background technology, compare, avoided the situation that weld nugget wearing and tearing, metal filament come off to occur, thereby extended service life.

The accompanying drawing explanation

Fig. 1 is sub-wire roll structure schematic diagram of the present utility model;

Fig. 2 is 1 inside face schematic diagram after the metal roller in Fig. 1 launches.

The specific embodiment

As depicted in figs. 1 and 2, roll dies comprised roller 2 in of the present utility model minute, in roller 2, was fixed with roll shaft 1, and stretch out respectively outside roller 2 two ends at roll shaft 1 two ends.Described roller 2 is the empty cylinder of metal, and in the present embodiment, the empty cylinder of described metal is the empty cylinder of corrosion-resistant steel (also can adopt the empty cylinder of other metal, such as the empty cylinder of aluminum alloy etc.).On the outside face of the empty cylinder of metal, be processed with spiral fashion convex tendon 3.Described spiral fashion convex tendon 3 is with extrusion press, to adopt the cold extruding mode empty cylinder extruding forms to metal, and described spiral fashion convex tendon 3 starts to be respectively oppositely from the axial centre of the empty cylinder of metal and forms to its two ends spiral extension.

With background technology, compare, the utility model need be at the empty tube outer surface welded wire of metal, and not only processing step is few, and technique is simple, and has saved metal filament, has reduced productive costs.Owing to not needing welded wire, avoided the situation that weld nugget wearing and tearing, metal filament come off to occur, thereby extended service life.
