When work, test dialyzing paper 4 is passed around respectively on two tensioning apparatus 3 and device for testing tensile force 2 first, works as survey
After examination dialyzing paper 4 is passed around according to ripple type structure, if there is tension or mistake in regulating roller 392 in test dialyzing paper 4
Song Shi, two about 39 adjusting branches start to work at the same time, and first adjust hydraulic cylinder 314 and start to work, and adjust hydraulic cylinder 314 and drive
Telescopic block 315 moves, and telescopic block 315 drives Y type adjusting rod 316 to move back and forth, and Y type adjusting rod 316 starts to adjust endless tensile
The tension of rope 31 starts to move between two line slide rails 38 being tensioned sliding block 391 under 31 tension force effect of endless tensile rope, and
The adjustment axis 393 being tensioned on sliding block 391 under the elastic force auxiliary of limit spring 310 is adaptively moved up and down, thus self
The tensile force of 392 pairs of regulating roller test dialyzing papers 4 is had adjusted, tension self-adaptability is good, it is not necessarily to manual adjustment tensile force,
Sigma compactness can be good, and applied widely, work efficiency is high；Device for testing tensile force 2 starts work after testing 4 tension self-control of dialyzing paper
Make, after test dialyzing paper 4 is tightly attached on two test rollers 231, two mobile test branches 22 start simultaneously at work, mobile electricity
Machine 222 is first started to work, and mobile motor 222 drives mobile lead screw 223 to rotate on two support ears 224, mobile 223 band of lead screw
Dynamic mobile sliding block 225 moves, and the limited support performances for limiting struts 226 and two limit optical axises 227 due to two assist can be with
So that mobile sliding block 225 stablizes movement on mobile lead screw 223, mobile sliding block 225 drives two test rollers 231 from two side directions
Guiding pulls test dialyzing paper 4, moves sliding block 225 at the same time and hook 233 is driven to pull two spring tension meters 23, work as test
When dialyzing paper 4 reaches suitable tensioning degree, the value of thrust for reading two spring tension meters 23 takes pulling force average value, the pulling force measured
Average value is exactly the resistance to compression force value testing dialyzing paper 4 and measuring, and eliminates accidental error existing for manual test pulling force, compressive property
Measuring accuracy is high, to realize the test accurate auto-tensioning test function of 4 compressive property of dialyzing paper, solves existing dialysis
Needed existing for paper compressive property manual test mode manual adjustment tensile force, complicated for operation, the degree of automation is low, tension self
Regulation performance is poor, tension performance is poor, the scope of application is small, manually adjusting test pulling force, there are error, compressive property measuring accuracy are low
With the problems such as working efficiency is low, purpose is reached.
The basic principles, main features and advantages of the invention have been shown and described above.The technical staff of the industry should
