Description
Technical field
Tank body vacuum-ness detecting device technical field is the utility model is related to, specially a kind of tank body vacuum degree measurement dress
Put.
Background technology
Vacuum packaging or oxygen barrier packaging are the packing techniques that food service industry generally uses.Its benefit is can to suppress microorganism
Growth and product oxidation.The key of vacuum packaging or oxygen barrier packaging is material and technique.In terms of material, it is desirable to have pair
Oxygen or gas have high barrier.In process aspect, it is desirable to which sealing is tight, air tight.At present, lacking effective detection method can
With the sealing of quick direct-on-line detection product, cause to pack underproof product coming into the market, compromise the profit of consumer
Benefit, while also bring negative impact to industry.
At present, it is hydrostatic(al) process in the general method of the context of detection of sealing.Packaging is put in water, by adding high pressure,
Look at that water can or can not infiltrate through packaging；Or vacuumize, bubble can or can not be formed by looking to be immersed in the surface of package in water.It is this
The defects of method one be can not on-line checking, second, can not detect on a large scale, third, false positive is easily produced, fourth, can not be automatic
Change, cost is high.Because being related to vacuumizing or pressurizeing link, in operation, continuity can not be ensured, therefore can not meet
The requirement of on-line checking.When detection, it is all very limited that product puts the amount in a vessel, added every time, more with regard to nothing
Method is observed, and therefore, can only be carried out minimal amount of sampling Detection to product, can not be accomplished the requirement that every product must be examined.Vacuumizing
During, water also the phenomenon bubbled can occur because pressure declines, and cause the bubble in surface of package observation not determine
Bottom is leakage, or caused by packaging external environment, easily forms false positive results.The pressurization that is related in operating process is taken out true
Sky, energy consumption are big.And result will observe by the naked eye, can not automatic detection, formed electronic signal, cause this detection method not
It can automate, detection takes time and effort, and the cost of detection is high.
In summary, during the vacuum of food or decompression are packed, it is badly in need of designing a kind of brand-new detection means, it is above-mentioned to overcome
Deficiency, reach realization packaging product online mass detection in good time, meet product per Bao Bijian, ensure product quality stabilization of dispatching from the factory
Beneficial effect.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Referring to Fig. 1, the utility model provides a kind of technical scheme：A kind of tank body vacuum-ness detecting device, it forms bag
Include：Spherical cap 10 and tank mouth set 11, described tank mouth, which covers, is provided with spherical cap 10 at the top of 11, in the described upper surface of spherical cap 10
Lever 6 is provided with the heart, release handle loose slot 13 is provided with the left of the described upper surface of spherical cap 10, described release handle is lived
Dynamic groove 13 is embedded in position adjustments handle 3, the described bottom of position adjustments handle 3 connection photodiode arc 12, described light
Photodiode array is provided with electric diode arc 12, light path 9, institute are provided with the right side of the described upper surface of spherical cap 10
The top of light path 9 stated is provided with light source 7, and described light source 7 is connected on circuit of light sources 8, and described photodiode array connects
It is connected on circuit two and circuit one, described circuit one includes qualified indicator lamp 2 and qualified power supply 1, described qualified indicator lamp
2nd, qualified power supply 1 and photodiode array form loop, and described circuit two includes unqualified indicator lamp 5 and unqualified power supply
4, described unqualified indicator lamp 5, unqualified power supply 4 and photodiode array form loop, the contact of described tank mouth set 11
Tank mouth pressuring spring piece 14 simultaneously makes it be combined with covering the contact 15 of inwall.
Operation principle：Tank body is packed after reduced pressure sealing, sealed membrane can form a cambered surface, its arc to tank body sunken inside
It is relevant with tank interior vacuum to spend size.Vacuum is bigger, and radian is bigger；It is on the contrary then on the contrary.When radian is 0, it is one
Plane.When vertical light is irradiated in plane, reflected light can return along original.After the cambered surface such as Fig. 3 is formed because of vacuum, instead
Penetrating light will reflect away along certain angle.Radian is bigger, and reflection angle is bigger.For the tank body fixed to one, in light path position
Put on the premise of fixing, there is linear dependence between its reflection angle and vacuum.On reflected light path, the pole of photoelectricity two is installed
Pipe array, collect reflected light and produce electric signal.Photodiode array divides two parts, and a part is in qualified caused reflection
In light path, and its both positive and negative polarity is integrated, it is electric after reflected light signal is received finally with power supply and green indicating lamp built-up circuit
Road, which is connected, causes indicator lamp to light；Another part outside qualified area, receive because vacuum not enough caused by small angle of reflection
Light, produce underproof indication signal.For specific technique, the difference of tank mouth diameter and sealing membrane material etc., it can cause
There is difference in the radian of identical vacuum lower sealing film depression, caused reflection angular is not during so as to cause qualified
Together.Photodiode array is arranged in a guide groove, and engages upper adjustable handle, by changing diode array
Position, to adapt to different inspection occasions.Therefore, the utility model is directed to specific workplace, needs to carry out school before use
Just.The method of correction is, is object with qualified products, is put into detecting system detection, regulation handle, until generation qualifying signal is
Only.For each detection object, because its tank mouth diameter is different, it is required for reconfiguring its accessory system.During detection, work as tank mouth
After set contact tank mouth, compressing can be produced to the spring leaf being mounted thereon, make the contact of its contact sleeve inwall, so as to connect light source
Circuit, produce detection signal.
As the further scheme of the utility model：The light-source control system is shown in Fig. 3.Under non-testing conditions, its
Spring leaf and contact separation.During detection, tank mouth pressuring spring piece, it is contacted contact, so as to form path, connect light source, production
Third contact of a total solar or lunar eclipse signal.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out with a variety of changes in the case where not departing from principle of the present utility model and spirit, repaiied
Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
