Description
Technical field
The utility model relates to a kind of flexible packaging device for detecting sealability, belongs to packing pick-up unit field.
Background technology
At present, the method that is used for the sealing property detection of flexible packing products is mainly negative pressure method (vacuum method), in existing negative pressure method proving installation, mostly the variation of proving installation pressure is to adopt pointer pressure and hand valve to jointly control, and mostly the control of time is to adopt manual control.Its shortcoming is: pointer pressure is changed greatly by surrounding environment influence, and easily occur that pointer is beated, indicated value instability etc. causes reading error large; Because hand valve is with the increase that opens and closes number of times, its mechanical wear is more serious, thereby causes sealing property to reduce, and serviceable life is shorter; Time is controlled and adopts manual control, control time out of true, malfunction.
Summary of the invention
For above-mentioned deficiency, the utility model provides a kind of flexible packaging device for detecting sealability.
The utility model is achieved through the following technical solutions: a kind of flexible packaging device for detecting sealability, by power supply, switch, timer, compressed-air power source, pressure-regulating valve, vacuum conversion equipment, solenoid valve, vacuum chamber, tested sample, tensimeter forms, it is characterized in that: vacuum chamber connects with solenoid valve, tested sample is placed in vacuum chamber, tensimeter is positioned on its connecting line, and connect with power supply, solenoid valve connects by the air entry of pipeline and vacuum conversion equipment, compressed-air power source connects through the air intake opening of pressure-regulating valve and vacuum conversion equipment, power supply connects with solenoid valve and timer respectively by switch.
Usefulness of the present utility model is: by this flexible packaging device for detecting sealability, can realize the sealing property of flexible packing products is detected, method of operating is simple, and accuracy of detection is high, adopts timer to strengthen the dirigibility of device, has saved manpower.
Accompanying drawing explanation
Accompanying drawing 1 is device for detecting sealability schematic diagram of the present utility model.
In figure, 1, power supply, 2, switch, 3, timer, 4, compressed-air power source, 5, pressure-regulating valve, 6, vacuum conversion equipment, 7, solenoid valve, 8, vacuum chamber, 9, tested sample, 10, tensimeter.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
A kind of flexible packaging device for detecting sealability, by power supply 1, switch 2, timer 3, compressed-air power source 4, pressure-regulating valve 5, vacuum conversion equipment 6, solenoid valve 7, vacuum chamber 8, tested sample 9, tensimeter 10 forms, it is characterized in that: vacuum chamber 8 connects with solenoid valve 7, tested sample 9 is placed in vacuum chamber 8, tensimeter 10 is positioned on its connecting line, and connect with power supply 1, solenoid valve 7 connects by the air entry of pipeline and vacuum conversion equipment 6, compressed-air power source 4 connects through the air intake opening of pressure-regulating valve 5 and vacuum conversion equipment 6, power supply 1 connects with solenoid valve 7 and timer 3 respectively by switch 2.
With reference to Fig. 1, using method and the principle of work of sealing pick-up unit are as follows:
Tested sample to be detected 9 is placed in vacuum chamber 8, and power supply 1 is opened, and first, switch 2 is opened, solenoid valve 7 energisings, and the air entry place of vacuum conversion equipment 6 starts to absorb the gas in vacuum chamber 8 by solenoid valve 7, reduces the air pressure in vacuum chamber 8; Compressed-air power source 4 is connected with the air intake opening of vacuum conversion equipment 6 by pressure-regulating valve 5, by regulating pressure-regulating valve 5, control the air-breathing speed of vacuum conversion equipment 6, make pressure in vacuum chamber 8 reach fast the pressure of qualification determination standard code, the pressure changing that tensimeter 10 shows in vacuum chambers 8.Secondly, when reaching the pressure of regulation, when switch 2 cuts out, solenoid valve 8 power-off, vacuum chamber 8 is in packing state, and timer 3 starts counting, until reach the time of qualification determination standard code, observe the interior tested sample 9 of vacuum chamber 8 whether leakage phenomenon (if leak, having Bubble formation) occurs, thereby judge the sealing property of tested sample 9.Finally, open switch 2, closes compression air power source 4, takes out tested sample 9, and tensimeter 10 indicating values are eliminated automatically, timer 3 automatic clears.
Wherein, owing to adopting solenoid valve 8, reduced the leakage of pressure in the process that makes to keep at pressure, in addition, this device tensimeter 9 adopts digital display vacuum meter, has eliminated the impact of surrounding environment, has improved accuracy of detection.
Wherein, by timer 3, control detection time, in the process of timer 3 timing, this flexible packaging device for detecting sealability carries out sealing property detection to tested sample 9 automatically, when timer 3 reached after the time of qualification determination standard code, whether range estimation tested sample 9 produces leakage phenomenon to judge that whether its sealing is qualified, take out tested sample 9, switch 2 is opened, timer 3 automatic clears, realize timing, improved the dirigibility of device.
Although the above is described embodiment of the present utility model by reference to the accompanying drawings; but the not restriction to the utility model protection domain; on the basis of specific embodiments of the present utility model, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection domain of the present utility model.
