Description
Affiliated technical field
The utility model relates to a kind of instrument that industry-by-industry flexible packaging product anti-pressure ability is detected.
Background technology
At present, to the compression resistance test of flexible packaging, the main method that adopts is to use the check of no accurate set pressure, checks as the method for exerting pressure with weight etc. both at home and abroad.The instrument and meter that the test to the flexible packaging sealing property is adopted has: the leakage test that is applicable to industry flexible packagings such as food, pharmacy, daily use chemicals; Instrument and meter to the leakage performance test of flexible packaging sealing has: to through fall, test specimen after the withstand voltage test reveals and seal strength tester, this instrument and meter is applicable to that mainly sealing-strength, heat seal quality and whole bag that flexible packaging that various hot sealing process form respectively seals the limit burst the quantitative determination of pressure, seal leakage performance.
As having of the power of applying for a patent of the instrument of pressure test: this utility model of plastic containers pressure test device (publication number CN2743826), has temperature compensating type cubical expansion test function, can carry out the test of conventionally test and industrial standard, this utility model of intelligent pressure detection instrument (publication number CN2447763) comprises joint, meter housing, power circuit, it is characterized in that: also have pressure transducer, amplifying circuit, the A/D change-over circuit, the liquid crystal LCD display, warning circuit, single chip microcomputer, the function expansion interface circuit, push-button combination operated control panel, tested pressure signal converts electric signal to by pressure transducer, after amplifying circuit amplification and A/D change-over circuit analog to digital conversion, the input single chip microcomputer carries out data processing and computing, the liquid crystal LCD display is delivered in the output of single chip microcomputer respectively, warning circuit, the function expansion interface circuit, single chip microcomputer is delivered in the output of operation control panel.
Along with the requirement of environmental protection and energy-saving and emission-reduction is more and more higher,, begin to be extensive use of flexible packaging in many fields such as food, health products, daily use chemicals, pharmaceutical producing enterprise, public institution, hospital and supermarkets.If what flexible package punch used is the flexible packaging of plastic material, this packing will be transported for long-distance, carries and be stacked, if any leakage, the damaged property loss and the people's lives and property potential safety hazard of enterprises and institutions of all can causing appear in this flexible packaging.
Therefore, invent a kind of whether can bearing certain pressure to flexible packaging, do not leak, the safety detector instruments and meters of damaged original packaging product not, become the pressing for of enterprise of producing liquid form product and adopting packed in flexible pouchy.
In national security supervisory department, check, use inspection unit, safety detection field, also need a kind of flexible packaging pressure security detector as the testing product security performance, guarantee the important means of transporting safely and using of product,
Goal of the invention
The purpose of this utility model is that a kind of instrument that the flexible packaging finished product is carried out the compressive resistance safety test according to set pressure and time will be provided, so that check the sealing intensity and the leaking performance of flexible packaging finished product under certain pressure.
Technical scheme
The purpose of this utility model is achieved in that the staff (annotates: set pressure scope 0-10 kilogram by button input set pressure on controller, whenever by once increasing by 0.2 kilogram) value and set pressure hold time and (annotate: setting-up time scope 0-59 minute, whenever by once increasing by 1 minute) data after, the flexible packaging finished product of filled with fluid (is annotated: the transfusion flexible bag that 50m1 does not wait to the volume of 500m1) place the pressurization cylinder lower, flexible pipe that is connected with tensimeter and infusion niidl are connected, infusion niidl is inserted the infusion port of transfusion flexible bag, connect the tensimeter that detects the flexible packaging actual pressure, start instrument then.Controller was controlled two-way three-way solenoid valve and was opened this moment, and by air inlet pressure regulator valve air feed, to the cylinder aerating, the moving component of cylinder moves downward, and presses to flexible packaging by two-way three-way solenoid valve.The pressure transducer that connects by communicating pipe is sent into controller to pressure detecting signal simultaneously, after the prime amplifier processing and amplifying, send into the MSP430 single-chip microcomputer, after inner A/D conversion, send MCU processing and set pressure to compare, control signal is sent into driver element, and drive two-way three-way solenoid valve by relay, after reaching set pressure (in ± 0.2 kilogram of scope), close two-way three-way solenoid valve, no longer to the cylinder aerating.If exceed set pressure, controller is controlled two-way three-way solenoid valve to atmospheric exhaust, if be lower than set pressure, controller is controlled two-way three-way solenoid valve to the cylinder aerating, constitutes closed-loop control like this, reaches metastable pressure.After the setting-up time of flexible packaging enforcement resistance to compression check arrived, controller drove two-way three-way solenoid valve to atmospheric exhaust by relay, and the moving component of cylinder moves upward, and takes out flexible packaging inspection at last.
The effect of invention
The utility model can be according to national packaging standard or company standard setup parameter (pressure limit 0-10 kilogram, time range 0-59 minute) carry out the efficient pressure safety verification, safety simple to operate can be tested the efficient height simultaneously to the flexible packaging of three kinds of different volumes types.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
