Abstract
The invention provides a simple air permeability tester. The tester comprises a base, an outer cylinder, an inner cylinder and a sample clamping device; the outer cylinder is fixedly connected to the base, the inner cylinder is fixed at the bottom of the sample clamping device, the cylinder diameter of the inner cylinder is less than the cylinder diameter of the outer cylinder, and the inner cylinder is movably arranged in the outer cylinder. The sample clamping device comprises an upper clamping plate and a bottom clamping plate, the upper clamping plate is positioned above the bottom clamping plate, corresponding through holes are arranged in the middle parts of the upper clamping plate and the bottom clamping plate, the upper clamping plate and the bottom clamping plate are connected by screws, and the sample clamping device also comprises a washer, wherein the washer is positioned between the upper clamping plate and the bottom clamping plate. An inner wall of the outer cylinder is provided with several guide rods, and the guide rods contact an outer wall of the inner cylinder. A cylinder wall of the inner cylinder is marked with volume scales. A gravity effect of the sample clamping device is used for promoting air in the tester to be discharged from a paper sample, so that the air permeability of the paper sample is tested. The tester has the beneficial effects that a simple principle is used, the structure is simple, and the tester is suitable for roughly testing the air permeability of the packing paper.
Description
Technical field
The present invention relates to the paper product densometer devices such as a kind of densometer, particularly food preservative packaging material.
Background technology
Air permeability refers under the effect of unit pressure reduction, passes through the average air flow of unit are sample or pass through the time required for known volume air within the unit interval.The mensuration of air permeability is to weigh an important indicator of antistaling agent packaging material.
Chinese patent CN103814285A entitled " air permeability sensing equipment ", it provides a kind of ventilation characteristic measuring equipment, and it includes having the measuring head of opening, vacuum pump, clamp arm and aperture disk, and aperture disk can rotate around its center axis.Aperture disk is arranged between pipe and vacuum pump, and wherein, aperture disk has multiple aperture.In addition, aperture disk includes: at least one gap, gap extends to the central opening of aperture disk from the region of the periphery of aperture disk, and when gap is in cleaning position, the contact area between the length in gap and the first end and the surface in aperture of in pipe is overlapping；And/or air jet nozzles, it aims to aperture disk.
The shortcoming of above-mentioned patent is that structure is complicated, and production cost is high.
Summary of the invention
It is an object of the invention to provide a kind of simple in construction, the simple densometer that production cost is low and easy and simple to handle.
The technical scheme is that a kind of simple densometer, including base, urceolus, inner core and folder sample device, described urceolus is fixedly connected on described base, the nozzle of described urceolus is arranged upward, described inner core is fixed on the bottom of described folder sample device, the nozzle of described inner core is arranged down, and the barrel dliameter of described inner core is less than the barrel dliameter of described urceolus, and described inner core is actively installed in described urceolus.
Described folder sample device includes that train wheel bridge and lower plate, described train wheel bridge are positioned at the top of described lower plate, and the centre of described train wheel bridge and lower plate is provided with the through hole of correspondence, and described train wheel bridge and lower plate are connected by screw.
Also including packing ring, described packing ring is between described train wheel bridge and lower plate.
The inner wall even distribution of described urceolus is provided with some guide rods, and described guide rod contacts the outer wall of described inner core.
The barrel of described inner core is marked with volume markings.
In the present invention, the action of gravity by folder sample device promotes the air in analyzer to discharge from pattern, thus records the air permeability of pattern, the invention has the beneficial effects as follows and utilizes simple principle, simple in construction, it is adaptable to the rough mensuration to the air permeability of wrapping paper.
Accompanying drawing explanation
Fig. 1 is densometer structure chart,
Fig. 2 is urceolus top view；
In figure, 1 is base, and 2 is urceolus, and 3 is inner core, and 4 is lower plate, and 5 is train wheel bridge, and 6 is packing ring, and 7 is screw, and 8 is guide rod.
Detailed description of the invention
Illustrate schematically the structure of densometer in FIG.Simple densometer includes base 1, urceolus 2, inner core 3 and folder sample device, described urceolus 2 is fixedly connected on described base 1, the nozzle of described urceolus 2 is arranged upward, described inner core 3 is fixed on the bottom of described folder sample device, the nozzle of described inner core 3 is arranged down, the barrel dliameter of described inner core 3 is less than the barrel dliameter of described urceolus 2, and described inner core 3 is actively installed in described urceolus 2.Principle is that the gravity by folder sample device promotes inner core 3 to decline in urceolus 2, thus air-out.
Described folder sample device includes that train wheel bridge 5 and lower plate 4, described train wheel bridge 5 are positioned at the top of described lower plate 4, and the centre of described train wheel bridge 5 and lower plate 4 is provided with the through hole of correspondence, described train wheel bridge 5 and lower plate 4 and is connected by screw 7.Folder sample device also includes packing ring 6, and described packing ring 6 is between described train wheel bridge 5 and lower plate 4.In use, pattern is positioned in the middle of train wheel bridge 5 and packing ring 6, and is screwed, and packing ring 6 is rubber washer, plays and sees good sealing function, it is therefore an objective to make air only discharge with the middle corresponding through hole of lower plate 4 from train wheel bridge 5.
The inner wall even distribution of described urceolus 2 is provided with some guide rods 8, and described guide rod 8 contacts the outer wall of described inner core 3, enables inner core to glide in urceolus smoothly.
The barrel of described inner core is marked with volume markings, the convenient air output reading unit volume, obtains air permeability values.
During use, in urceolus 2, add a certain amount of working oil.Pattern is inserted between train wheel bridge 5 and lower plate 4, tighten screw.Inner core is extracted to a certain scale, decontrol, press stopwatch simultaneously, read inner core and decline the time required during unit scales, be the air permeability of this sample.
