Description
Technical field
The utility model relates to a kind of device of nondestructive testing package body, particularly relates to the proving installation that test box cigarette small packaging is leaked.
Background technology
Sealing is very large on the impact of packaging product quality, seals bad can impact, makes moist, salt fog, and mould etc. are widely used in doctor's material equipment, medicine, the fields such as food.In the packaging process of product, due to the impact of various factors, may produce when involution Lou seal, pressure wear or exist because of material itself crack, micropore, and form the aperture of inside and outside connection, these all can have a negative impact to pack content.The particularly packing of product such as food, medicine, daily use chemicals, sealing will directly affect the quality of product.If as vacuum, gas flush packaging poor sealing, even if having employed the shelf life that high barrier material also directly can shorten product, certain economic loss is caused to enterprise.From this aspect, sealing propertytest is carried out to packaging product and is enterprise image, obtains one of long-term economic benefit feasible road.
It is good again to seal, and also can there is certain leakage, the packaging of positive confinement does not exist, particularly the capsule packaging of similar cigarette, and be the heat-sealing utilizing BOPP film, sealing is relevant with the temperature-time material of heat-sealing, and testing result sealing is not very desirable.
The method for conducting leak test of current employing comprises following several:
1. visual method, visual examination is exactly direct visual perception with or without because of mechanical damage, the poorly sealed and mistake envelope that causes.Mainly check that those have the packaging obviously losing envelope.
2. the place of losing envelope is suspected in the inspection of tallcum powder method talcum powder on packing, and sprinkles talcum powder, then uses hand push-through packs, if the air of the packaged interior discharge of talcum powder blows, then illustrates that packaging loses envelope.
3. sealing property detector method, the detection method of sealing property detector is on packing, make a call to a gas injection aperture, then its pressure is made to reach 1.2 atm higher by gas injection aperture to injecting compressed air in sealed packet vanning, close gas injection switch, observe the pressure change in seal box, after 5 seconds kinds, pressure is constant, favorable sealing property is described, otherwise loses envelope.At present, these three kinds of methods have applicable one side, also there is obvious defect.Visual examination, simple and convenient, but be only applicable to significantly lose envelope.Talcum powder checks, the impact by package shape, human factor is comparatively large, and its reliability is not high.Detector detects, although reliability is high, while detecting, pack destroyed, reseal from punching to, working link is various, is unfavorable for carrying out the work, and be the packaging of good seal to testing result, testing process will cause many spinoffs.
4. discharge method, discharge method can be used for measuring cigarette case packaging, carton package and other with tygon or polypropylene film carry out wrapping up hybrid packed on packaging film sealing.But the method is not suitable for the packing box using shrink wrapping, Wrapped in Cellophane or foil packages.The validity of use traffic method testing package sealing may be defective because of packaging quality, as packaging film having loose film, wrinkle film or foreign matter etc. and reduce.
Summary of the invention
In order to solve above-mentioned technical matters, first object of the present utility model is to provide a kind of proving installation tested box cigarette small packaging and leak, and this apparatus structure is simple, and it is convenient to implement, under the condition not destroying sample, quick and precisely can judge whether box cigarette small packaging leaks.
In order to realize above-mentioned object, the utility model have employed following technical scheme:
A kind of proving installation tested box cigarette small packaging and leak, this device comprises the test cavity of O-ring seal, blowing plant, piston apparatus and triplate line, described test cavity, blowing plant are connected with piston apparatus the one end being arranged on triplate line respectively, and respectively with one end pipeline of piston apparatus, blowing plant on be provided with the first valve and the second valve, with test cavity one end pipeline on be provided with pressure transducer.
As preferably, described test cavity is metal, and the volume of volume and cigarette package body is close.
The utility model, owing to have employed above-mentioned technical scheme, utilizes pressurized air plenum, according to the ratio of the displacement difference after balance, judges leakage rate size.Apparatus structure of the present utility model is simple, and it is convenient to implement, and under the condition not destroying sample, quick and precisely judges whether box cigarette small packaging leaks.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is made a detailed explanation.
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is made a detailed explanation.
A kind of proving installation tested box cigarette small packaging and leak as shown in Figure 1, this device comprises test cavity 1, blowing plant 2, piston apparatus 3 and triplate line 4, test cavity 1 is metal and with O-ring seal 5, the volume of volume and cigarette package body is close.Described test cavity 1, blowing plant 2 are connected with piston apparatus 3 one end being arranged on triplate line 4 respectively, and respectively with one end pipeline of piston apparatus 3, blowing plant 2 on be provided with the first valve V
1with the second valve V
2, with test cavity 1 one end pipeline on be provided with pressure transducer P.
Test the method for testing that box cigarette small packaging is leaked, the method adopts above-mentioned device, comprises the following steps:
1) do not put test sample, closed test cavity 1, first by the plate washer of piston, moves to Far Left, closes the first valve V
1with the second valve V
2;
2) the second valve V is opened
2, make pressurized air enter in cavity, air pressure reaches P
1, close the second valve V simultaneously
2, open the first valve V
1, after the plate washer of piston moves, write down the displacement S of movement, blowdown pressure letdown;

0, be completed, blowdown pressure letdown;
4) put into tested sample in test cavity 1, press aforesaid operations equally, record the displacement S of movement
1, opening the first valve V
1time, start to clock, after reaching balance, the equilibration time recorded is t, is completed, blowdown pressure letdown;
5) according to time t, tested thing determines whether gross leak, and under normal circumstances, t>0.5s, if t is less than 0.5 second, then illustrates gross leak; According to following formula:
Size according to A judges leakage rate size.
Adopt above-mentioned method to detect box cigarette small packaging, detect data as follows:
First pressurized air is filled with cavity, recording pressure is 5KPa, and after emptying, recording S is 4.96 cm, and standard testing body, in test cavity 1, records S
0be 0.03 cm, this value changes according to manifold volume size.
Put into tested sample in test cavity 1, press aforesaid operations equally, for cigarette rigid pack, record displacement S
1be 0.5 cm; For the soft box packaging of cigarette, record displacement S
1for 0.6cm; For gross leak sample, record displacement S
1for 1.2cm; According to repetitive measurement, draw and be greater than 85% for cigarette rigid pack A, it is qualified to be judged to be; Being greater than 80% for cigarette soft box packaging A is judged to be qualified, counts in state sample to obtain A(hard by formula)=90.4%, A(soft)=88.4% be certified products.
