For solving the problems of the technologies described above, the present invention is achieved in that
A kind of flexible barrier material seal strength tester is characterized in that: it is made of PLC (Programmable Logic Controller), the input that is connected with PLC, output unit and Test Host body;
This Test Host body comprises frame and the main folder tool, the auxiliary clamp that are arranged on the frame; The main folder tool is made up of last anchor clamps and lower clamp two parts, connects sensor on the last anchor clamps, and lower clamp is fixed in the spirit alive, and along the upper and lower displacement of track, and lower clamp also has displacement transducer by the step motor drive precision lead screw in the spirit of living; Upper and lower anchor clamps are two flat-nose pliers that can clamp sample, and their jaw is on same plane, and this plane is parallel with the leading screw center line; This auxiliary clamp is the multi-faceted adjustable flat-nose pliers of a cover energy, is to be fixed in the spirit alive of another set of track, and this work spirit is along the upper and lower displacement of track by the step motor drive precision lead screw;
Two stepping motor is connected with PLC respectively, and by its control displacement and velocity of displacement, direction; Sensor also is connected with PLC respectively with displacement transducer and transmits test signal to PLC.
Described flexible barrier material seal strength tester is characterized in that: this input, output unit comprise touch-screen, printer.
Described flexible barrier material seal strength tester is characterized in that: this sensor is connected with PLC by A/D converter with displacement transducer.
Described flexible barrier material seal strength tester is characterized in that: the descending speed of this auxiliary clamp is 1/2 of main folder tool downstream rate.
By technique scheme, the technique effect that the present invention has is:
Product of the present invention manufactures and designs according to relevant requirements among the EN868-1 " needing the medical device package material and the system of sterilization ", is used to test the sealing intensity of flexible barrier material.It carries out option and setting with touch-screen to test, can show the relation curve of pulling force and displacement, and shows maximal seal strength and average sealing intensity automatically, thereby makes whether qualified conclusion, and can go out test result by printer prints on request.

Embodiment
See also Fig. 1,2, it is a kind of flexible barrier material seal strength tester of the present invention, it is characterized in that: it is made of PLC 1, the input that is connected with PLC 1, output unit and Test Host body, and this input, output unit comprise touch-screen 7, printer 8.
This Test Host body comprises frame 2 and the main folder tool 3, the auxiliary clamp 4 that are arranged on the frame 2; Main folder tool 3 is made up of last anchor clamps 31 and lower clamp 32 2 parts, connect sensor 51 on the last anchor clamps 31, lower clamp 32 is fixed in the spirit 33 of living, and the spirit 33 of living drives precision lead screw 34 along track 35 upper and lower displacements by stepper motor 61, and lower clamp 32 also has displacement transducer 52; Upper and lower anchor clamps 31,32 are two flat-nose pliers that can clamp sample 10, and their jaw is on same plane, and this plane is parallel with leading screw 34 center lines; This auxiliary clamp 4 is the multi-faceted adjustable flat-nose pliers of a cover energy, is to be fixed in the spirit 42 of living of another set of track 41, and this work spirit 42 is to drive precision lead screw 43 along the upper and lower displacement of track by stepper motor 62; These auxiliary clamp 4 descending speed are 1/2 of main folder tool 3 downstream rates.
As Fig. 2, two stepping motor 61,62 is connected with PLC 1 respectively, and by its control displacement and velocity of displacement, direction; Sensor 51 also is connected with PLC 1 respectively with displacement transducer 52 and transmits test signal to PLC 1, and this sensor 51 is connected with PLC 1 by A/D converter 91,92 with displacement transducer 52.
The process of manipulating of instrument of the present invention is:
After the energising, the screen display master menu is pressed test specimen numbering on the master menu, test temperature, test humidity, sealing intensity setting, and keypad input back is confirmed successively.Return master menu, by being metered into first zero setting behind the submenu, on anchor clamps on the main folder tool, put the standard test weight of 1N, 5N, 10N, 20N then successively, the contrast screen is gone up the reading that the power value shows, should be not more than with standard test weight value error ± 2%, promptly demarcate to demarcating metering power value and use.Return master menu, press test specimen physical size and method of testing regulation, select specimen width, seal length, afterbody to grip mode, anchor clamps translational speed, setting finishes.Adjust the lower clamp up-downgoing of main folder tool, the potted line that makes test specimen in the main folder tool is perpendicular to draw direction, and keeps enough lax, and test specimen is not stressed when the test beginning, but has displacement transducer stressed immediately downwards when lower clamp.Require to regulate auxiliary clamp according to method of testing again, make afterbody (potted line) and draw direction or be 90 °, or be 180 °, or do not have support (free state).Clamping finishes, by test, and the test beginning, the lower clamp of main folder tool is descending gradually, and potted line is peeled off gradually, and auxiliary clamp is according to the requirement of method of testing, or hold afterbody and be 90 °, or be close to afterbody and be 180 °, constant with the angle of 1/2 descending guarantee afterbody of main folder tool downstream rate and test specimen.Peel off fully until potted line (afterbody), test finishes.Screen display: the sealing intensity setting value of maximal seal strength (N/M), even sealed intensity (N/M) and previous input relatively after, make the conclusion of acceptance or rejection.Demonstrate the form and the curve of printing by printing, on paper, export by printer prints.So just finished test to flexible barrier material seal intensity.
Being preferred embodiment of the present invention only in sum, is not to be used for limiting practical range of the present invention.Be that all equivalences of doing according to the content of the application's claim change and modification, all should be technology category of the present invention.
