Abstract

A roller comprises a roller body, an adjusting wheel, at least two variable roller faces and wedge-shaped convex strips. The adjusting wheel is arranged in the roller body, is coaxial with the roller body and is axially provided with a wedge-shaped outer surface, the variable roller faces are arranged along the circumferential surface of the roller body, are supported by the wedge-shaped convex strips and are connected with the wedge-shaped convex strips, one end of each wedge-shaped convex strip is connected with the bottom surface of the corresponding variable roller face, the other end of each wedge-shaped convex strip is supported on the wedge-shaped outer surface of the adjusting wheel, a mounting sleeve used for mounting the adjusting wheel is connected with one end of the roller body, a mandrel with an inner connecting hole is connected to the other end of the roller body, mounting holes are arranged on the mounting sleeve, and the wedge-shaped convex strips can penetrate through the mounting holes. Owing to a mechanical expansion shaft structure, axial and radial expansion and contraction are realized via mechanical force, and on the basis that the mechanical expansion shaft structure is simple, safe and reliable and is small in size, high in capacity and convenient to operate, the roller is particularly suitable for a situation that inner and outer diameters of large rolls of various coiled materials in the paper processing field are inconsistent, and is unlimited by work sites or goods yards.

Description

A kind of running roller

Technical field

The utility model relates to the paper for daily use processing technique field, particularly the running roller used of the rolling of one way of life paper using processing equipment, unreeling structure.

Background technology

In the prior art for the uncoiling (unreeling) of large-scale heavier coiled material class with batch (rolling) and usually adopt fixed boom main axis of dilatation (hydraulic pressure or air pressure), the swelling shaft invariant position, the large volume of coiled material by other means or equipment mechanism it is sent on the swelling shaft, very complicated, cost is high.For the uncoiling (unreeling) of small-sized lighter coiled material class with batch (rolling) and usually adopt air-expanding shaft, optical axis (band tapered sleeve or chuck), easily, but can not bear heavy lift in the prior art.Also have a kind of hydraulic pressure swelling shaft in the prior art, hydraulic power unit that must a movement of configuration, oil cylinder is arranged in the swelling shaft, and is bulky, and maintenance capacity is large, easily reveals and pollutes poor reliability.

Summary of the invention

The purpose of this utility model is for above-mentioned existing problems and deficiency, a kind of mechanical expansion shaft is provided, this mechanical expansion shaft is expansion and the contraction that realizes the diameter of axle by mechanical force, simple in structure at mechanical expansion shaft, volume is little, and load is large, on the safe and reliable and easy to operate basis, make the inconsistent occasion of the large volume internal-and external diameter of each coiled material in its special adaptation paper conversion field, also be not subjected to the restriction in work-site or goods yard.

The technical solution of the utility model is achieved in that

Running roller described in the utility model, be characterized in that described running roller comprises roll body, be installed in the roll body and with the roll body coaxial device axially have the regulating wheel of wedge shape outside face along it, at least two variable roll surfaces of arranging along the roll body periphery, the wedge shape raised line of each variable roll surface of support and connection, one end of wherein said each wedge shape raised line is connected with variable roll surface bottom surface, its other end is supported on the wedge shape outside face of regulating wheel, the center shaft of described regulating wheel is to being provided with adjusting shaft, one end of described roll body is connected with the installation sleeve for the device regulating wheel, its other end is connected with the mandrel with interconnecting hole, be provided with the mounting hole that passes for the wedge shape raised line on the wherein said installation sleeve, and an end of described adjusting shaft is connected with the interconnecting hole of mandrel, the end that described adjusting shaft is connected with the interconnecting hole of mandrel is provided with outside thread, and correspondence is provided with negative thread in the interconnecting hole of described mandrel.

The utility model is owing to adopting the structure of mechanical type main axis of dilatation, realize expansion and the contraction of the diameter of axle by mechanical force, simple in structure at mechanical expansion shaft, volume is little, load is large, on the safe and reliable and easy to operate basis, make the inconsistent occasion of the large volume internal-and external diameter of each coiled material in its special adaptation paper conversion field, also be not subjected to the restriction in work-site or goods yard.

Below in conjunction with accompanying drawing the utility model is further described.
