Description
Technical field
This utility model belongs to storage device technique field, relates to a kind of vacuum bucket for storing capactive film.
Background technology
Thin film capacitor, owing to having the most excellent characteristic, is widely used on analog circuit, capactive film be for
Produce the material of thin film capacitor, in capactive film production process through plated film, the technique such as cut after, in order to manufacture thin-film capacitor
Device, storage environment is required higher by capactive film, it is impossible in atmosphere, usual capactive film is more than at relative humidity in long-time exposure
In the space of 40%, its storage less than 10 days, therefore in prior art capactive film produce by more limitation
Property, it is impossible to a large amount of production is deposited, and causes the equilibrium of supply and demand of capactive film to be difficult to control, and the waste of its resources of production is serious.
China's patent (notification number: 202193320U；The day for announcing: 2012.04.18) disclose one for electric capacity film roll bag
The fixing device of dress, it includes the most a piece of partition matched with carton, every partition is equipped with at least two through holes, through hole
In be provided with and match silently with electric capacity film roll；Being silently cylindricality, the diameter of this cylindricality is equal to the diameter of through hole, and one end silently
Circumferentially arranged with radial protrusion；Partition is two；One plane of partition is provided with cushion pad.
Fixing device in above-mentioned patent documentation, owing to not having the storage environment of sealing and vacuum, is only used for of short duration placement
Capactive film, it is impossible to long-time placement capactive film also ensures its quality, and when electric capacity film roll is placed in this fixing device, on
Material process and blanking process are cumbersome, the most convenient.
Summary of the invention
This utility model is the problems referred to above existed for existing technology, it is provided that a kind of capactive film vacuum bucket.
Technical problem to be solved in the utility model is: how to provide a kind of and convenient uses and can the device of long-time storage capactive film
Tool.
The purpose of this utility model can be realized by following technical proposal:
A kind of capactive film vacuum bucket, including the staving with inner chamber, it is characterised in that the two ends of described staving are respectively
Offering opening one and the opening two connecting described bowl inner chamber, the most dismountable connection in two ends of described staving has and can seal
The end cap one of stifled described the opening one and end cap two of opening two can be blocked, described end cap one or/and end cap two be provided with can
Connection bowl inner chamber and extraneous breather line, described breather line is additionally provided with control valve.
Its operation principle is as follows: can be from the opening one of this bucket end through plated film and the capactive film after cutting membrane process
Or opening two puts in staving, by end cap one, opening one is blocked after piling, by end cap two, opening two is blocked,
Then breather line is connected with vacuum pump, opens control valve, is discharged by the air in bowl inner chamber by vacuum pump, then will
Control valve closing so that in vacuum environment in bowl inner chamber, having completely cut off oxygen and dampness, capactive film is true staving inner sealing
Can long storage time in Altitude.Through overtesting, utilize this bucket can be brought up to 2～3 resting period of capactive film
Individual month, the highest.
After bowl inner chamber evacuation, produce the effect in external atmosphere pressure of negative pressure, the end cap one at staving two ends and end cap two
Lower absorption, on staving, is connected firmly, does not comes off, and the most convenient when installing；When needing to take out capactive film, it is only necessary to open
