Specifically, for a use scene, the ink pad 5 selects an ink pad and an ink pad respectively to test the service lives of the stamp 2 and the ink pad 5; for consumables, the lives of the stamp 2 and the ink pad 5 were tested using ordinary paper and rice paper; aiming at different people, the set force of the stress plate 21 and the ink pad 5 is adjusted to meet the force of each age group, the service lives of the seal 2 and the ink pad 5 are tested, the force is set to be a little smaller when the strength of children is small, and the force is set to be a little larger when the strength of young people is large.

The working process is as follows:

stamp pad test mode: firstly, fixing a stamp pad 5 on a small rotary platform 19 of a stress platform 1, fixing a stamp 2 on a clamp 3, installing test paper, adjusting unreeling tension and a handle of a paper feeding mechanism 30, and enabling paper to freely move towards a reeling direction; secondly, starting the tester, namely driving the stamp 2 to press downwards by a Y-axis motor, and returning the Y-axis motor when a set force is applied to the stamp pad 5 (the set force is induced by the force sensor 6); when the Y-axis motor returns to the proper position, the X-axis motor drives the stamp 2 to move to the position of the stress plate 21, the Y-axis motor drives the stamp 2 to press down again, and when a set force is applied to the stress plate 21, the Y-axis motor returns; and fourthly, when the Y-axis motor returns to the right position, the X-axis motor drives the seal 2 to return, when the X-axis motor returns to the right position, the next cycle is started, and when the number of the transverse seals reaches a set value (the transverse seals refer to the length direction of the paper), the paper feeding motor works to enable the paper to travel for a certain distance, and meanwhile, the winding motor works to pack up the tested test paper. Judging the result of the ink pad service life test: when the printing color applied to the roll paper becomes poor or defective, the number of stamps is recorded, and the result is a stamp pad life value.

And (3) seal testing: fixing seal 2 on anchor clamps 3, adjusting the X axle motor, making anchor clamps 3 remove to atress board 21 position, start the test, Y axle motor pushes down to a setting force, then the return accomplishes a stamp like this, when transversely stamping several to certain figure, paper feed motor work accomplishes the line changing, and test paper that the test was packed up in winding motor work simultaneously. Judging the result of the seal life test: the same as the pad test mode.

The back-and-forth movement is along the width direction of the force-bearing platform 1, and the up-and-down movement is along the height direction of the force-bearing platform 1. The X-axis motor is used for driving the support frame 7 to be in front-back sliding fit on the guide rail 8, and the Y-axis motor is used for driving the clamp 3 to be in up-down sliding fit on the slide rail 9.
