Abstract
The invention discloses an air expansion shaft for a coiling and uncoiling device. The air expansion shaft comprises a hollow shaft, an expansion air bag and expansion blocks, wherein the hollow shaft comprises a main shaft body and two end shafts; a plurality of long-strip-shaped holes are formed on the main shaft body; the expansion blocks are arranged in the long-strip-shaped holes; the expansion air bag is arranged in the main shaft body; the lower surface of the expansion block is contacted with the expansion air bag; air inflation devices are connected to the two end shafts; and durable layers are arranged on the external surfaces of the two end shafts. According to the mode above, uniform pressure is exerted on the internal wall of a coiling barrel; two ends of the air expansion shaft are high in durable performance; and the air expansion shaft has long service life, and is simple and practical.
Description
Technical field
The present invention relates to the winding/unwinding device field, particularly relate to a kind of air-expanding shaft for winding/unwinding device.
Background technology
Air-expanding shaft all is used in many enterprises in modern times.Air-expanding shaft is a kind of special rolling, unreeling shaft, namely passes through the axle that high-pressure aerated rear surface (digital bar) can projection, and axle that venting rear surface part (digital bar) is retracted rapidly is called air-expanding shaft.Airpressure axle, main axis of dilatation, flatulence axle, inflatable roller, inflation axle, pressure axis, inflatable roller etc. are again in its title variation.Existing air-expanding shaft all is the single face inflation, so that air-expanding shaft is inhomogeneous for the pressure of reel inwall, can cause reel to tilt; In addition, the relatively severity of existing air-expanding shaft two ends wearing and tearing, the service life of having reduced air-expanding shaft.
Summary of the invention
The technical matters that the present invention mainly solves provides a kind of air-expanding shaft for winding/unwinding device, can solve the defective that exists in the prior art, and air-expanding shaft is even to the pressure of reel inwall, and the air-expanding shaft two ends are wear-resistant, long service life.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of air-expanding shaft for winding/unwinding device is provided, comprise: hollow shaft, swelling gasbag and expansion block, described hollow shaft comprises main shaft and two end axles, offer a plurality of strip shapes hole on the described main shaft, described expansion block is arranged in the described strip shape hole, described swelling gasbag is arranged on main shaft inside, the lower surface of described expansion block contacts with described swelling gasbag, all be connected with gas filled device on described two end axles, described two end axle outside faces are equipped with wearing layer.
In a preferred embodiment of the present invention, described wearing layer is chromium coating.
In a preferred embodiment of the present invention, described chromium coating thickness is 0.15 ~ 0.2mm.
In a preferred embodiment of the present invention, described expansion block is arranged in the described strip shape hole, and expansion block cooperates with strip shape hole gap.
In a preferred embodiment of the present invention, described gas filled device is cylinder.
In a preferred embodiment of the present invention, described hollow shaft adopts alloy steel to make.
The invention has the beneficial effects as follows: the present invention is used for the air-expanding shaft of winding/unwinding device, and even to the pressure of reel inwall, air-expanding shaft two ends wear resisting property is good, and long service life is simple and practical.

Fig. 1 is the structural representation that the present invention is used for air-expanding shaft one preferred embodiment of winding/unwinding device;
The mark of each parts is as follows in the accompanying drawing: 1, swelling gasbag, 2, expansion block, 3, main shaft, 4, the end axle, 5, gas filled device, 6, wearing layer.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
See also Fig. 1, the embodiment of the invention comprises:
A kind of air-expanding shaft for winding/unwinding device, comprise: hollow shaft, swelling gasbag 1 and expansion block 2, described hollow shaft comprises main shaft 3 and two end axles 4, offer a plurality of strip shapes hole on the described main shaft 3, described expansion block 2 is arranged in the described strip shape hole, and described swelling gasbag 1 is arranged on main shaft 3 inside, and the lower surface of described expansion block 2 contacts with described swelling gasbag 1, all be connected with gas filled device 5 on described two end axles 4, described two end axle 4 outside faces are equipped with wearing layer 6.
All be connected with gas filled device 5 on described two end axles 4, because both sides all are provided with gas filled device 5, can inflate simultaneously, so that air-expanding shaft is even to the pressure of reel inwall.
Described wearing layer 6 is chromium coating.
Described chromium coating thickness is 0.15 ~ 0.2mm.
Chromium coating has increased the wear resisting property of end axle 4, has prolonged the service life of air-expanding shaft.
Described expansion block 2 is arranged in the described strip shape hole, and expansion block 2 cooperates with strip shape hole gap, and expansion block 2 is firmly withstood the reel inwall under the impetus of swelling gasbag 1, and the band movable reel rotates.
Described gas filled device 5 is cylinder.
Described hollow shaft adopts alloy steel to make, and is durable in use.
The present invention is used for the air-expanding shaft of winding/unwinding device, and even to the pressure of reel inwall, air-expanding shaft two ends wear resisting property is good, and long service life is simple and practical.
The above only is embodiments of the invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes specification sheets of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
