It is attached.Air-breathing is carried out to adsorption roller by installation blower, negative-pressure sucking is generated around adsorption roller, thus to the amorphous of high-speed motion
Strip is carried out grabbing band and be batched.Permanent magnet adsorbing roller is by inlaying permanent magnet in adsorption roller outer end face, due to amorphous thin ribbon
It is iron-based band, so generating adsorption capacity to it by permanent magnet surrounding magnetic field, is adsorbed.Most common negative pressure is inhaled
Attached roller mainly passes through welding straight channel, is easy to produce vortex in runner in adsorption roller rotation process, requires height to power of fan,
Adsorption process noise is obvious simultaneously；Although permanent magnet is applied to adsorption roller strong adsorption force, some live sundries of absorption are easy,
Do not allow easy to clean, and erroneous for installation, permanent magnet need to be regularly replaced, influences the preparation efficiency of amorphous band.
Summary of the invention
For the deficiency for solving existing structure, the first problem that the present invention solves is that the adsorbent chamber of adsorption roller is weldering at present
Connect straight channel, air-flow is easy to produce vortex in the channel, it is high to the power requirement of blower, and adsorption process noise is big the problems such as,
Therefore it is high to provide a kind of adsorption efficiency, noise and adsorption roller flow passage structure low in energy consumption.
It is that some live sundries of absorption are easy for existing permanent magnet that the present invention, which solves second technical problem, is not allowed
Easy to clean and the problems such as permanent magnet need to be regularly replaced erroneous for installation.The present invention provides a kind of energization magnet and replaces permanent magnetic thus
The absorption roll structure of iron.
In order to solve the above technical problems, its technical solution is as follows: novel adsorption roller is mainly by spiral shell in main shaft, tapered sleeve, locking
Mother, outer nut, left end cap, sealing ring, housing, coil, spacer ring, bracket, inner cavity, right end cap, gland, slip-ring part position composition.
In order to reach the above object, main shaft of the invention is connected by bolts with tapered sleeve, and the main shaft is hollow structure.
Outer nut is connected by bolts with left end cap, locks inner nut by engaging with the outer nut, by the tapered sleeve and left end cap
It compresses.By processing seam allowance positioning, the inner cavity is tapered, to intermediate recess, can make air-flow for the left end cap and inner cavity, bracket
Facilitate and is flowed into centre.It is helical structure among the inner cavity, bending direction is opposite to the direction of rotation, and air-flow is facilitated inwardly to flow
It is logical.Three loop coils are embedded in housing and are spaced from each other by spacer ring, radial direction have the bracket with it is described interior
Chamber separates.Three groups of coil circuits by series connection with it is in parallel.Adsorption roller right end is the right end cap and gland, and the conduction is sliding
Ring is coupled with the gland by seam allowance positioning bolt, is powered when realizing rotation status for the coil.The housing and bracket
Upper several through-holes of processing, facilitate airflow.By sealing ring between the main shaft and inner cavity, pass through the pressure of the locking inner nut
Consolidation now seals.Adsorption roller increases adsorption capacity by the cross action in negative pressure and magnetic field, improves the crawl efficiency of amorphous thin ribbon.
Preferably, adsorption roller forms joint force by negative-pressure adsorption chamber and energization magnet, improves the crawl and suction of adsorption roller
Attached power.
Preferably, through three winding displacement circles of installation inside adsorption roller, centre is separated the adsorption roller with spacer ring, passes through slip ring
It is powered and is powered off to coil, to generate magnetic field adsorption capacity to amorphous ribbon.
Preferably, the adsorption roller inner cavity is conical cavity, can reduce the generation of circulation during negative-pressure adsorption, reduces pump
Function.
It preferably, is helical duct in the middle part of the adsorption roller inner cavity, bending direction is with adsorption roller direction of rotation on the contrary, can make
It is laminar flow into inner chamber gas, reduces vortex and pump work in flow process, reduces noise.
Beneficial effects of the present invention:
(1) in amorphous ribbon curly course, due to the method that runner uses the conical surface and spiral phase structure, helical flow path makes
Gas quickly updates, and making air-flow is laminar flow in flow process, reduces the whirling motion in flow process, while among main shaft and inner cavity
Increase seal washer, to improve the reduction pressure loss, improves the blower utilization rate of adsorption capacity, reduce noise.
(2) energization magnet replaces permanent magnet, by when generate magnetic field, when no power, does not have magnetic field.Adsorption roller can be reduced
The sundries on surface can reduce maintenance and replacement magnet time, improve working efficiency.
