Description
Technical field
The utility model relates to a kind of detection tool, is specifically related to a kind of enclosure-type flexible packing products air tightness and detects tool.
Background technology
Flexible packaging generally refers to that paper using, aluminium foil, fiber, plastic sheeting and the bag made by their compound, box, cover, encapsulating etc. are for packing preservation product.Such as in flexible packaging food and medicine, whether the leak gas sealing of i.e. flexible packaging of flexible packaging directly affects food and medicine storage life, is especially placed with deoxidizer etc. in some food flexible packings as food fresh keeping material, once flexible packaging gas leakage, deoxidizer will lose efficacy, and food is apt to deteriorate.Occurred the device whether some detection flexible packing products leak gas in prior art, it can carry out automatic leakage air detection to the independent inflatable packaging bag of small-sized bakery.But accuracy is difficult to ensure, in addition, existing checkout equipment program complexity is loaded down with trivial details, and detection time is longer, is unfavorable for enterprise's High-efficient Production.
Utility model content
For the problems referred to above, the utility model provides a kind of air-leakage test tool, its object is to: simplify checkout equipment and testing process, reduces detection time, improves detection efficiency.
Technical solution of the present utility model:
Air-leakage test tool, it is characterized in that: comprise frame, the worktable be located in frame, for being used for placing the table surface of article to be detected on the left of described worktable, on the right side of described worktable, detection case is installed, described detection case is by pipeline and vacuum plant and air pressure list catenation, described vacuum plant comprises vacuum pump, and described vacuum pump is connected with detection case by pipeline, and the pipeline between vacuum pump and detection case is provided with vacuum meter; Described rain glass is connected with alarm by pressure transducer; Described detection case is by the hollow structure of transparent design, is provided with opening, by removable type cover plate by closure of openings at detection case top; Be provided with the pressing plate that can slide up and down along detection case in described detection case, article to be detected are positioned over below pressing plate, and described pressing plate is double-deck pull telescopic structure, and its surface is provided with multiple air hole.
Described detection case material is glass or tempered glass or bakelite or acrylic.
Also vacuum buffer tank is provided with between described vacuum pump and detection case.

Described vacuum pump is mechanical vacuum pump.
Described detection case is also connected with timer and time display.
Described detection case is also provided with fluid level scale line.
The beneficial effects of the utility model:
The utility model higher than the characteristic of normal sealing soft package article, causes article in pressure to be greater than sealing that external pressure fast judge article by rapid vacuumizing by the inner remaining a certain amount of gas of the soft package article that utilizes sealing bad, air pressure; By vacuumizing detection case, making the sample soaked in water produce inside and outside differential pressure, observation rain glass, thus judging that in sample, gas escapes situation, judging the sealing property of sample with this; By vacuumizing detection case, make sample produce inside and outside differential pressure, also Observable sample expands and specimen shape recovery situation after release vacuum, judges the sealing property of sample.
By the hydraulic pressure that the pressing plate of up-down adjustment sensing chamber inside can bear according to different demand sample, make test environment more flexible, in addition, the double-deck pull telescopic structure that the platen design of sensing chamber inside becomes surface to have air hole conveniently can be picked and placeed sample; Built-in time display, pressurize starts timer synchronization timing, and facilitate user record to observe the dwell time, pressurize terminates timer automatic clear.
Accompanying drawing explanation
