Abstract
The utility model relates to a combined soft packaging material intensity tester, which observes tearing situations of material by slowly increasing pressure, and precisely measures intensity of the material. The utility model comprises a pressure cavity, and a partial opening of the pressure cavity can be coated with combined soft package material, which forms a hermetic sealing space, the pressure cavity is connected with a pressure display device, and the utility model is characterized in that the pressure cavity is connected with a gas buffering device. The utility model has the advantages that the gas buffering device can slowly increase pressure in an air pressure cavity, which is convenient for precisely testing, recording, and measuring preciseness is improved.
Description
Technical field
The utility model belongs to specialized equipment, relates in particular to a kind of strength tester that is used for composite soft packaging material.
Background technology
Present flexible packing material, having a kind of is compound substance, it mainly is composited by aluminium foil layer, ply of paper, low density polyethylene layer; When opening the drink flexible packaging, puncture compound substance with suction pipe usually, for making things convenient for customers, the intensity of compound package material will suit.
The strength test technology of present composite soft packaging material is the moment pressure when the single face of compound substance is exerted pressure its destruction of test, and it is qualified that its pressure is judged to above setting, otherwise be judged to defective; There is bigger personal error in this measuring technology because the pressure when breaking is moment during observation, record is difficulty relatively, generally need repeatedly get its mean value, and this causes the duplication of labour again.
Up to the present, the instrument that does not also have a kind of accurate test compound flexible packing material intensity.
Summary of the invention
The purpose of this utility model provides a kind of strength test instrument of composite soft packaging material, and it observes situation and the accurate intensity of measuring material that material is torn by boosting lentamente.
For achieving the above object, the utility model adopts following technical scheme, and it comprises pressure chamber, and the local opening part of pressure chamber can cover composite soft packaging material makes it become seal cavity, and pressure chamber is connected with pressure-display device, and pressure chamber also delays to fill to put with gas and connects.
The technical scheme of the utility model also comprises the light source of the reverse side that can shine composite soft packaging material; The pressure chamber bottom is provided with the slide plate that can vertically slide, and the slide plate below is provided with cam; Described light source be arranged in the pressure chamber or the light-source chamber of pressure chamber below in; Roof forms top cover, and opening is positioned at top cover central authorities, and opening part is provided with the compound substance hold down gag; The pressure chamber diapire forms base, and base has supporting leg; The pressure chamber sidewall forms column in the position, angle, column and described slide plate form and be slidingly matched.
The utility model is put owing to being provided with slow the filling of gas, pressure in the atmospheric pressure cavity is slowly risen, become a process thereby breaking of composite soft packaging material finished by moment, be convenient to accurately to determine and the air pressure of record when breaking, improved the degree of accuracy of strength test; In addition owing to be provided with the light source at the irradiation composite soft packaging material back side, the therefore microphenomenon that can clearly observe breach, quality that can experimental material.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, the utility model comprises the frame of quadrangular shape, and the top of frame is provided with top cover 3, and frame lower forms base 9, and base 9 has supporting leg 10 on four angles; Four angles of frame are column 11, the middle part is provided with light-source chamber, light source 7 is set in the light-source chamber, the diapire of light-source chamber is a slide plate 16, and the below of slide plate 16 is provided with the cam gear 8 that is fixed on the base 9, bulb is set as light source 7 in the light-source chamber, the upper wall of light-source chamber is transparent pressure-resistant plate 12, the chamber wall surrounded pressure chamber 5 around transparent pressure-resistant plate 12 reached with described top cover 3, and the middle position of top cover 3 is provided with opening 2, and opening 2 places are provided with guide rail 4 and compound substance hold down gag; Transparent pressure-resistant plate 12, slide plate 16 and whole light source chamber and column 11 form and are slidingly matched; Pressure chamber 5 also by air admission hole 14 and pressure-display device and gas slow fill to put connect (not shown).
Slow the filling of described air pressure is changed to prior art, repeats no more.
Transparent pressure-resistant plate 12 is connected by sliding part 6 with pressure chamber, and contact position is provided with sealing gasket 13; Sliding part 6 central openings 5, transparent pressure-resistant plate 12 is arranged on the position of perforate 5; Touch composite soft packaging material 1 and compress the formation sealing for sliding part 6 is risen, the highest part of sliding part 6 is provided with rubber ring 15.
During actual the use, at first tested composite soft packaging material 1 is placed on cover plate 3 openings 2 places by guide rail 4, and it is compressed with hold down gag; Put bright light source 7 then, slow again rotating cam device 8, the rotating drive slide plate 16 of cam, light-source chamber and transparent pressure-resistant plate 12 upwards slide along column 11, the rubber ring 15 of high part until sliding part 6 touches composite soft packaging material 1, pressure chamber 5 forms sealing states at this moment, then gas slow fill to put by air admission hole 14 in pressure chamber 5, charge into gas inchmeal, the air pressure in it becomes big gradually; Because composite soft packaging material 1 is paper plastic-aluminum three's compound substance, so in pressure chamber 5 internal gas pressures become big process gradually, extend minimum aluminium foil and be torn at first, be ply of paper then, be only the LDPE (Low-density polyethylene plastics) layer at last; After least the aluminium foil of printing opacity is torn, because light source 7 can be radiated at the back side of composite soft packaging material 1 by transparent pressure-resistant plate 12, therefore light can enter between the fiber of paper through transparent plastic layer, fiber is by the light tight printing opacity that gradually becomes in air pressure increase process gradually, finally be torn, and the extensibility of LDPE (Low-density polyethylene plastics) is best at this moment, also be not torn, can under illumination, well observe paper, the hole of two kinds of materials of aluminium foil engages the microphenomenon at place, and then can find out cause the normal valve system error of breaking (as all continuously same angle exist tear the time fault then for mould microcosmic flaw or rough due to), and then both can test intensity, can also find out the defect of manufacturing and also be rectified and improved.
The utility model is for providing good watch window between tester, light, the air pressure three, the corresponding presentation and the precise information of each spot pressure of collection that can be careful.
In sum, the utility model can make the pressure in the atmospheric pressure cavity slowly rise owing to be provided with slow the filling of gas and put, thereby makes breaking of composite soft packaging material finish the process that becomes by moment, be convenient to accurately to determine and the air pressure of record when breaking, improved the degree of accuracy of strength test; In addition owing to be provided with the light source at the irradiation composite soft packaging material back side, the therefore microphenomenon that can observe breach clearly, meticulously, and accurate detected intensity parameter.
