Description

Let off roll

Technical field

The utility model is related to a kind of unwinding device, more particularly to a kind of let off roll.

Background technology

It is raw material usually using steel band when producing color steel, and coiled steel band needs to be placed on and carried out on let off roll Unreel.Steel coil strip is that let off roll is connected on the inwall of paper web by steel coil strip on a paper web.Gas is used in the prior art Rise by axle as let off roll, also have direct optical axis as let off roll.When unreeling different size of steel coil strip, its internal paper web Size also can be different, but these let off roll can not well adapt to the change of paper web diameter.

Utility model content

The purpose of this utility model is to provide a kind of let off roll, can easily be adjusted to adapt to different inner diameters Paper web.

Above-mentioned technical purpose of the present utility model technical scheme is that：A kind of let off roll, including Be connected with least two groups support components in rotary shaft, rotary shaft, support component includes at least two support feets, support feet include with The affixed stop sleeve of rotary shaft and one end sliding are connected to screw thread on the studdle in stop sleeve and studdle and connected The end abutment of the location nut connect, location nut and stop sleeve coordinates.

By using above-mentioned technical proposal, when let off roll supports steel coil strip, entered by support feet come the inwall to paper web Row support, while studdle can stretch out from stop sleeve, then by location nut, determines the length that studdle stretches out Degree, so that studdle abuts the inwall of paper roll, completes the support to steel coil strip, and the paper roll of different-diameter, support Screw rod can stretch out different length to adapt to.And after the completion of unreeling, reversely rotate location nut, you can release support spiral shell Support of the bar to paper web, can remove paper web afterwards, more convenient.

Preferably, support component is two groups, every group of support component includes four support feets.

By using above-mentioned technical proposal, two groups of support components can be adjusted by the opening at the two ends of paper web, and Have more than two, then internal support component is inconvenient to adjust, meanwhile, two groups of support components also can guarantee that to the steady of paper web support It is qualitative；And four support feets of every group of setting, it may further ensure that the stability of support.

Preferably, the other end that studdle is connected with stop sleeve is connected with supporting plate, supporting plate is curved.

By using above-mentioned technical proposal so that the area contacted during support with paper roll is larger, reduce the pressure at abutting, So that paper web is less likely to occur to damage, while support is also more stablized.

Preferably, surface of the supporting plate away from studdle side is provided with non-slip texture.

By using above-mentioned technical proposal, the frictional force between supporting plate and paper web inwall is increased so that when unreeling It is not easy to skid between supporting plate and paper web.

Preferably, surface of the supporting plate away from studdle side is provided with cushion.

By using above-mentioned technical proposal so that it is more abundant that supporting plate is contacted with paper web, further ensures support Stability.

Preferably, be provided with connecting plate between the end of the studdle of two adjacent groups, the two ends of connecting plate are respectively and branch The end for supportting screw rod is affixed.

By using above-mentioned technical proposal, on the one hand, in rotational positioning nut, studdle is limited by connecting plate System, studdle will not follow location nut to rotate, so that what studdle can be stably is protruding；On the other hand, When the studdle of side is protruding, the studdle of opposite side can be driven to stretch out so that stabilization during support more, And the convenience when rotating the location nut of opposite side also more, improve operating efficiency.Simultaneously can also be by connecting plate to paper Cylinder is abutted, the area of the abutting of increase so that support is more stablized.

Preferably, side of the connecting plate away from rotary shaft is also connected with cushion.

By using above-mentioned technical proposal so that connecting plate contacts more abundant with the inwall of paper web, is further ensured that The stability of support.

Preferably, offering guide groove on the inwall of stop sleeve, length direction of the guide groove along stop sleeve is set, branch It is connected with support screw rod and slides the projection coordinated with guide groove.

By using above-mentioned technical proposal so that studdle can only be slided along stop sleeve length direction, be limited The rotation of studdle itself so that during rotational positioning bolt, studdle can be stretched out by screw-driven, convenient to adjust Section.

Preferably, rotary shaft is hollow pipe.

By using above-mentioned technical proposal, reduce the deadweight of let off roll, facilitate it to install.

Preferably, the affixed restraining position ring block in the two ends of rotary shaft.

By using above-mentioned technical proposal, let off roll can be carried out when being unreeled spacing, prevent that let off roll can be with The transverse shifting of meaning.

In summary, the utility model has the advantages that：The paper web of different-diameter can be supported, at the same regulation compared with For convenience, support relatively stable.
