Abstract
The utility model belongs to the field of packaging quality detecting equipment and discloses a tightness detecting device for a packaging bag, which comprises a container, a threaded screw cover, a water inlet pipe and an exhaust pipe, wherein the container is used for containing water and the packaging bag to be detected, the threaded screw cover is used for sealing an opening of the container, and the water inlet pipe and the exhaust pipe are communicated with the container; and a water inlet valve and an exhaust valve are respectively installed on the water inlet pipe and the exhaust pipe. The packaging bag is put into the device, the water inlet pipe is connected to a tap water source, the container is filled with water, the water can slowly permeate the bag with bad tightness due to the action of pressure so that the water content of an object is increased, and therefore, the detection on the tightness of the packaging bag is realized. The tightness detecting device is directly connected with the tap water source and carries out detection of packaging tightness by utilizing the principle of pressure difference between the pressure of tap water and air in the packaging bag, therefore the detecting device has simple operation method and low cost.
Description
Technical field
The utility model belongs to packaging quality checkout equipment field.
Background technology
So-called package encapsulation is meant that packaging bag or packing box prevent the characteristic that other materials enter or content overflows.The packaging bag kind of people's use at present is more, in the production run of packaging bag or packing box, because production link is many, the leakage that may produce heat sealing is sealed, pressure is worn or crack, the micropore of material itself, and form inside and outside aperture or the strength weak point that is communicated with, cause the difference of sealing property, but the scene is difficult to again check out, along with the growth of time, seepage can occur or seal tight and material that the cause problem that becomes damp and rotten.
Traditional method that is used for the detection of flexible packaging sealing mainly is water decompression method (being vacuum method or bubble method again), being about to packing to be detected is immersed in the water in the transparent vessel with anchor clamps, with transparent vessel sealing and connect a vacuum generator it is vacuumized, whether produce bubble with low-power microscope or visual inspection packaging bag and judge its sealing, accuracy of detection is lower.Advanced at present package encapsulation detection method has differential detection method, displacement-type Leak Detection, ultrasound examination, helium mass spectrum leak detection method, tracer gas technique detection method, is difficult to but these method costs are higher popularize at short notice.
The utility model content
For these reasons, technical problem to be solved in the utility model provides a kind of more easy packaging bag device for detecting sealability.This device compares that the conventional device method of operating is simpler, and precision is higher, and cost is lower.
A kind of packaging bag device for detecting sealability comprises being used to be filled with water and the container of packaging bag to be detected, is used for the gland bonnet that the opening with container seals, the drain tap that is provided for connecting the inlet valve at water source on the container and is used for exhaust.
Also be connected with water inlet pipe and gas outlet on the container, inlet valve and drain tap are installed in respectively on water inlet pipe and the gas outlet.
Container also is provided with tensimeter, is used to show the pressure of internal tank.
Compared with prior art, the utlity model has following advantage:
Packaging bag device for detecting sealability described in the utility model directly links to each other with the tap water water source, the principle of utilizing the pressure differential in tap water pressure and the packaging bag can cause the content water cut of the packaging bag of poor sealing to increase is carried out the detection of packaging bag sealing, method of operating is simple, the precision height, cost is low.
Description of drawings
Fig. 1 is an embodiment physical construction synoptic diagram;
Fig. 2 is the embodiment working state schematic representation.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Embodiment
As shown in Figure 1, this packaging bag device for detecting sealability is made up of drain tap-6 on the inlet valve-4 on the screw thread screw capping-2 of container-1, vessel port place, water inlet pipe-3, the draft tube 3, gas outlet-5, the gas outlet 5 and the tensimeter-7 that is used for detection receptacle hydraulic pressure.
Fig. 2 is the present embodiment working state schematic representation, and using method and principle of work are:
Packaging bag to be detected is placed in the container 1, with screw thread screw capping 2 container 1 is sealed, open inlet valve 4 and drain tap 6, in container, inject tap water, treat in the container 1 after the fills with water, close drain tap 6, but do not close inlet valve 4, then the hydraulic pressure in the container can remain on the water feeding pressure that 0.1 ~ 0.4Mpa(is a tap water in the general city always) owing to wherein have solid material to do support therein, the space is compressed to a certain degree and just can change, so pressure can be littler than hydraulic pressure.Under the effect of inside and outside differential pressure, the water in the container can penetrate in the packaging bag of poor sealing, thereby the moisture of this packaging bag is increased.The water cut of taking out the measurement content after a period of time is left standstill in packaging bag in water,, illustrate that then this packaging bag sealing is poor if water cut increases.
The sealing that the utility model is particularly suitable for the pesticide flexible package bag detects, and especially is fit to sealing requirements is sealed than higher being used to the sealing detection of the packaging bag of the moisture-sensitive formulations of pesticide such as water dispersible granules.For example, when from aluminizer packaging bag and full aluminium film package bag, selecting a kind of wrappage of better tightness, pesticide water dispersible granules can be packed with aluminizer and full aluminium film respectively, and measurement products moisture, packaged product is put into this pick-up unit, store 10 days, measure moisture then, found that the packaged products moisture of aluminizing increases.Hence one can see that, and the better tightness of full aluminium film package bag is more suitable for doing the packaging bag of pesticide water dispersible granules.
The above embodiment has only expressed embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be noted that; for the person of ordinary skill of the art; under the prerequisite that does not break away from the utility model design; can also make some distortion and improvement; concrete shape as container can be changeable, and gland bonnet can also be other shape except the screw thread screw capping, and the particular location of gland bonnet and quantity also can be changeable; do not limit at this, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claim.
