Abstract
The utility model provides a kind of axle sleeve of expanding diameter of air shaft, this axle sleeve comprises the sleeve body of tubular structure, internal diameter and the diameter that air-expanding shaft diameter matches, external diameter is slightly less than material reel that will be socketed of sleeve body, the lateral wall of sleeve body offers along the circumferential direction evenly distributed some axial notches, axial notch is embedded be connected to can with the anti-skidding press strip of material reel close contact.Expanding diameter of air shaft axle sleeve of the present utility model, structure is simple, easy to operate, with low cost, for the material reel of different size, only need be socketed the axle sleeve of different wall, just can realize the multiplex object of an axle, greatly alleviate the productive costs of enterprise, be one and be worthy to be popularized and truly feasible technical scheme.
Description
Technical field
the utility model relates to a kind of rolling, unwinding device, particularly relates to a kind of air-expanding shaft, more specifically relates to a kind of axle sleeve of expanding diameter of air shaft.
Background technology
Air-expanding shaft is through the axle that high-pressure aerated rear surface chain is protruding, venting rear surface chain is retracted rapidly, and be mainly used in the locking to material core reels such as toilet roll, film or cloth and release, material reel is generally papery or plastic material.During use, material reel is placed on air-expanding shaft, when needs material loading is locked, only need inflate air-expanding shaft, and the chain on air-expanding shaft protruding can withstand outside material reel, when needs discharging is loosened, only needs venting, and the chain on air-expanding shaft can be retracted rapidly.Use due to air-expanding shaft have easy to operate, fast, do not damage material reel, air-expanding shaft as independent parts of rolling, unwinding device, be widely used in pack, printing and paper industry mechanical equipment in.Internal diameter due to material reel is not unified, different material or for the different requirements of user to converted products, the inside barrel diameter of material differs greatly sometimes, need the air-expanding shaft being equipped with plurality of specifications to adapt to the material reel of different inner diameters, the increase of enterprise's productive costs certainly will be caused like this, also cause the waste of resource simultaneously.For addressing this problem, external producer once researched and developed to adopt and was socketed the method for gas filled device outward to expand the diameter of air-expanding shaft at air-expanding shaft, but this apparatus structure is complicated and price is higher, was not suitable for applying.
Summary of the invention
For solving above Problems existing, the purpose of this utility model is to provide simple, the cheap expanding diameter of air shaft axle sleeve of a kind of structure.
For realizing above object, expanding diameter of air shaft axle sleeve of the present utility model, comprise sleeve body, it is characterized in that: described sleeve body is tubular structure, internal diameter and the diameter that air-expanding shaft diameter matches, external diameter is slightly less than material reel that will be socketed of sleeve body, the lateral wall of sleeve body offers along the circumferential direction evenly distributed some axial notches, axial notch is embedded be connected to can with the anti-skidding press strip of material reel close contact.
In order to increase the friction force of axle sleeve and material reel, the upper surface indentation of above-mentioned anti-skidding press strip, this toothed section protrudes from the notch of groove.
For the ease of the handling of axle sleeve, an end lateral wall of above-mentioned sleeve body axis stretch out form position limiting convex ring, the other end lateral wall inwardly shrinks and forms ring-type round platform.
In order to make anti-skidding press strip and material reel madial wall more fit, the upper surface of above-mentioned anti-skidding press strip and bottom surface are cambered surface.
Above-mentioned sleeve body is elastomeric material, and anti-skidding press strip is aluminium.
Expanding diameter of air shaft axle sleeve of the present utility model, owing to adopting, internal diameter and the air-expanding shaft diameter that will be socketed match, external diameter is slightly less than the cylindrical body of the diameter of material reel as sleeve body, then can utilize the air-expanding shaft of same specification, expand the size of diameter as required, the material reel of different inner diameters is adapted to by the thickness adjusting side wall of shaft sleeve, realize the object that an axle is multiplex, and some anti-skidding press strips are along the circumferential direction evenly set at the lateral wall of sleeve body, axle sleeve and material reel can be made to combine closely, easily realize coaxial running.Expanding diameter of air shaft axle sleeve of the present utility model, structure is simple, easy to operate, with low cost, is particularly suitable for processing with clientsupplied materials enterprise making full use of same specification air-expanding shaft, for reducing productive costs developing new way.

Detailed description of the invention
As shown in Figure 1,2,3, 4, expanding diameter of air shaft axle sleeve of the present utility model, comprise the sleeve body 1 of a cylinder-like structure, internal diameter a and the diameter that air-expanding shaft diameter matches, external diameter b is slightly less than material reel that will be socketed of sleeve body, the lateral wall of sleeve body offers along the circumferential direction evenly distributed some axial notches 11, the axial both ends of sleeve body, lateral wall stretch out position limiting convex ring 12, other end lateral wall of forming anchor ring and central axis in one end inwardly shrinks the ring-type round platform 13 forming table top and central axis; Axial notch is embedded is connected to anti-skidding press strip 2, and the upper surface of anti-skidding press strip and bottom surface are cambered surface, the upper surface indentation 21 of anti-skidding press strip, and this toothed section protrudes from the notch of groove, as shown in Figure 5; Sleeve body adopts elastomeric material to make, and anti-skidding press strip adopts alumina based material to make.
Expanding diameter of air shaft axle sleeve of the present utility model, during use, as shown in Figure 6, first two of same specification axle sleeves are socketed on the both ends of material reel 3, the lateral wall of axle sleeve and the madial wall of material reel is made to form compact siro spinning technology, the position limiting convex ring of axle sleeve is positioned at the end face of material reel, then is passed at the center of air-expanding shaft 4 from axle sleeve; During material loading locking, inflate air-expanding shaft, the chain on air-expanding shaft protruding can withstand the madial wall of axle sleeve, and axle sleeve drives material reel to rotate with air-expanding shaft; When discharging is loosened, only need venting, the chain on air-expanding shaft is retracted rapidly, and air-expanding shaft then can easily exit.
The utility model adopts the axle sleeve of low cost to replace the air-expanding shaft of high cost, for the material reel of different size, only need be socketed the axle sleeve of different wall, just can realize the multiplex object of an axle, greatly alleviate the productive costs of enterprise, be one and be worthy to be popularized and truly feasible technical scheme.
