Description
Technical field
The present invention relates to measuring device fields, in particular it relates to a kind of toothbrush bristle strength tester.
Background technique
According to China's correlation toothbrush bristle strength criterion, toothbrush bristle intensity is classified as soft, medium, hard three ranks, it is still, existing
Modern toothbrush manufacturing industry there is no the detection device or detection means for effectively judging toothbrush bristle intensity, usually according to bristles
The strength of materials used in beam carries out fuzzy restriction to toothbrush bristle intensity, and consumer generally requires root when buying toothbrush
According to the toothbrush bristle of itself actual demand selection proper strength, therefore toothbrush bristle intensity need to be carried out finer qualitative and fixed
Amount analysis.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of toothbrush bristle strength tester of detectable toothbrush bristle intensity,
The toothbrush bristle strength tester can the intensity to toothbrush bristle accurately measured, to accurately analyze and assess
Toothbrush bristle strength grade.
Its technical solution is as follows:
A kind of toothbrush bristle strength tester, comprising: bottom plate, the toothbrush fastening machine for being used to fasten toothbrush being arranged on bottom plate
Structure, grid, driving toothbrush or the driving mechanism of grid back and forth movement, the force value sensor being connect with toothbrush or driving mechanism, inspection
Dial gauge, display interface and the shell of toothbrush and grid relative position are surveyed, force value sensor will be between grid and toothbrush bristle
The moving resistance that friction generates is converted into toothbrush bristle bending force, then bending force data is exported in the display interface.
In the present invention, when measuring the intensity of toothbrush bristle, the length of toothbrush bristle is first measured, then uses toothbrush fastening machine
Structure fastens toothbrush, and the pieces of toothbrush is face-down, keeps grid or toothbrush mobile by driving mechanism, grid is made to be located at tooth
Below bristle tuft, the height of toothbrush is adjusted with toothbrush height regulating mechanism, until toothbrush bristle just contact grid, then by hundred
Divide table zeroing, then continued to adjust toothbrush height with toothbrush height regulating mechanism, until dial gauge is shown as the tooth acted on grid
Bristle tuft is about half of total length or so, then drives toothbrush or grid to carry out back and forth movement, at this time the pieces and grid of toothbrush
Friction generates active force between lattice, i.e. toothbrush bristle or grid back and forth movement is able to detect by moving resistance, force value sensor
Moving resistance and toothbrush bristle bending force is converted by this moving resistance out, then in the display interface by data output, operation
Person passes through display interface it can be seen that toothbrush bristle is bent force data, and then according to the bending force numerical assessment toothbrush bristle seen
Grade.It in practical operation, is provided according to industry, when bending force is less than 6N, then toothbrush bristle intensity is set to soft, works as bending
When power is between 5~8N, then toothbrush bristle intensity is set to it is medium, when bending force be greater than 7N when, then by toothbrush bristle intensity
It is set to hard, when pieces intensity is between 5~6N, can be both set to soft, and can also be set to medium, pieces intensity is between 7~8N
Between when, can both be set to medium, can also be set to strong.In the present invention, bottom plate plays a supportive role, convenient for the peace of other component
Dress, shell is for protecting other assemblies and making toothbrush bristle strength tester appearance looks elegant.
The driving mechanism includes screw rod, guide rod, the sliding being arranged on screw rod and guide rod in one of the embodiments,

Realize the back and forth movement of grid.It interacts between toothbrush bristle when grid movements, to determine the curved of toothbrush bristle
Qu Li.
The toothbrush retention mechanism includes collet, first clamping piece, first clamping piece guide rod, in one of the embodiments,
One knob and second intermediate plate, the first clamping piece and second intermediate plate are located at below collet, shape between first clamping piece and second intermediate plate
At the cavity of accommodating toothbrush.More specifically, shown first clamping piece guide rod is elastic guide rod, spring has been arranged outside guide rod.Measurement
When toothbrush bristle intensity, toothbrush is first inserted into toothbrush bristle strength tester from collet, and pieces position is placed in
In cavity between one intermediate plate and second intermediate plate, screwing the first knob, then first clamping piece squeezes toothbrush, and it is fastened toothbrush,
Realize the fixation to toothbrush.
The toothbrush height regulating mechanism includes the second guide rod and the second knob in one of the embodiments, and described the
Two guide rods and the second knob are connect with collet.In practical operation, the length with the toothbrush bristle of grid effect is to the toothbrush measured
The bending force of pieces has certain influence, and for more accurate measurement data, the length usually with the pieces of grid effect is about pieces
The half of total length, it is therefore desirable to which the relative altitude of toothbrush and grid is adjusted.The present invention is to pass through rotating second knob
The height of collet is adjusted, to realize the adjusting to toothbrush height.
The quantity of the first clamping piece guide rod is 2 in one of the embodiments, is located at the two sides of the first knob;
The quantity of second guide rod is 2, is located at the two sides of the second knob.
The measuring head of the dial gauge is contacted with second intermediate plate in one of the embodiments,.When toothbrush bristle and grid
When just contacting, dial gauge is read and is zeroed, is at this time 0 with the toothbrush bristle length of grid effect, continue through height adjustment
Mechanism adjusts toothbrush height, that is, screws the second knob, then collet height reduces, and second intermediate plate height also reduces, the survey of dial gauge
The altitude information that amount head detects is the length of the toothbrush bristle acted on grid, when the data that dial gauge is shown are about toothbrush
When the half of pieces total length, the length of pieces is the one of toothbrush bristle total length when toothbrush bristle and grid act at this time
Half, then toothbrush reaches predeterminated position.
The display interface is display screen in one of the embodiments,.
The beneficial effects of the present invention are: the present invention drives toothbrush or grid to carry out back and forth movement by driving mechanism, this
When toothbrush toothbrush bristle and grid between friction generate active force, force value sensor be capable of detecting when this active force and by this
Kind of power is converted into toothbrush bristle bending force, then in the display interface by data output, operator pass through display interface it can be seen that
Toothbrush bristle is bent force data, so that toothbrush bristle strength tester be enable accurately to survey the intensity of toothbrush bristle
Amount, accurately analyzes and assesses toothbrush bristle strength grade.
