Description
Technical field
The utility model relates to capacitor aluminium foil manufacture fields, more particularly to a kind of leading for capacitor aluminium foil production
Electric roller.
Background technique
With the rapid development of domestic electronics industry, aluminium electrolutic capacitor is more widely applied, and performance requirement is also more next
It is higher.It in electronic aluminum foil corrosion processing technology, is rolled using conductive rollers and is contacted with aluminium foil, transmit electric current to aluminium foil.Due to
On this aluminium foil production line, conductive rollers usually will be by very big electric current, therefore would generally increase on the roller surface of conductive rollers
Add one layer of metal (usually silver-colored) with high conductivity.Existing method have directly power on silver coating in roller surface, will be silver-colored
Foil package is welded on roller surface or whole roller is made of silver.But plating mode is used, the thinner thickness of silver layer, abrasion
Fastly, service life is short；Welding manner is wrapped up using silver foil, binding force is weak between silver foil and roller surface, it is easy to appear gap, this
Very big heat can be generated in use, and heat often will cause aluminium foil surface deformation and situations such as wrinkle after accumulating
Occur, seriously affects the performance and quality of product；And whole roller is made of silver, cost is very high.
In addition, the roller surface smoother of existing conductive rollers, thus its friction is small between aluminium foil, it will usually
Cause aluminium foil to skid, aluminium foil is caused wrinkle phenomenon occur.
Summary of the invention
The utility model is intended to provide a kind of conductive rollers, to solve the above technical problems.For this purpose, what the utility model used
Specific technical solution is as follows:
A kind of conductive rollers, in the production of capacitor aluminium foil, including conductive roller, roll shaft and ring flange, the conduction
Roller is mounted on the roll shaft by the ring flange, cooling-water duct is equipped in the roll shaft, which is characterized in that described to lead
Electric roller, roll shaft and ring flange are made of copper, copper alloy, stainless steel or aluminium, cold spraying one on the upper surface of the conduction roller
Layer silver powder coating.
Further, the thickness of the silver powder coating is between 0.2 millimeter to 5 millimeters.
Further, friction is processed on the silver powder coating form structure.
Further, it is axial notch that the friction, which forms structure,.
Further, it is circumferential recess that the friction, which forms structure,.
Further, it is latticed groove that the friction, which forms structure,.
Still further, the width of groove is 10-20 millimeters, and depth is 1/2 or more of silver powder coating layer thickness.
The utility model by adopting the above technical scheme, has the beneficial effect that through cold spraying mode, silver powder last layer with
Combination between roller surface is unusually strong, is not in gap, and the thickness of silver powder coating can be controlled according to actual needs
System, not only reduces manufacturing cost, but also extend service life, improves the quality stability of product.
Detailed description of the invention
To further illustrate each embodiment, the utility model is provided with attached drawing.These attached drawings are in the utility model discloses
A part of appearance mainly to illustrate embodiment, and can cooperate the associated description of specification former come the running for explaining embodiment
Reason.Cooperation refers to these contents, and those of ordinary skill in the art will be understood that other possible embodiments and sheet are practical new
The advantages of type.Component in figure is not necessarily to scale, and similar component symbol is conventionally used to indicate similar component.
Fig. 1 is the stereoscopic schematic diagram of the conductive rollers of the utility model；
Fig. 2 is the viewgraph of cross-section of conductive rollers shown in FIG. 1.
Specific embodiment
Now in conjunction with the drawings and specific embodiments, the present invention will be further described.
Referring to Fig.1 with 2, the conductive rollers 1 in a kind of production for capacitor aluminium foil are described.Conductive rollers 1 may include conduction
Roller 10, roll shaft 20 and ring flange 30, wherein conductive roller 10 is mounted on roll shaft 30 by ring flange 30.It is equipped in roll shaft 10
Cooling-water duct 110, to be cooled down to conductive roller 10.The shape of conductive roller 10, roll shaft 20, ring flange 30 and conductive bar 40
Shape size is well known to the skilled person, and is not discussed herein.Conductive roller 10, roll shaft 20 and ring flange 30 by copper,
Copper alloy, stainless steel or aluminium are made.In order to improve conductive roller 10 carrying high currents ability, the upper surface of conductive roller 10
One layer of silver powder coating 40 of upper cold spraying.Since cold spray process has the coating of spraying good, the sprayable any thickness of compactness
Feature, thus the thickness size of silver powder coating 40 selected according to the actual situation (such as service life, manufacturing cost etc. because
Element).In general, the thickness of silver powder coating 40 can be between 0.2 millimeter to 5 millimeters.
In order to increase the frictional force between conductive roller 10 and aluminium foil, friction is processed on the silver powder coating 40 and is formed
Structure 50.In the shown embodiment, it is axial notch that friction, which forms structure 50,.Certainly, friction forms structure 50 and is also possible to week
To groove, latticed groove or other structures.
Preferably, the width of groove is 10-20 millimeters, and depth is 1/2 or more of silver powder coating layer thickness.
Although specifically showing and describing the utility model in conjunction with preferred embodiment, those skilled in the art is answered
This is understood, in the spirit and scope for not departing from the utility model defined by the appended claims, in form and details
On the utility model can be made a variety of changes, be the protection scope of the utility model.
