Description
Technical field
This utility model is related to cutting performance detection field, especially a kind of to detect setting for rotary shaver sharpness
It is standby.
Background technology
In production practices, whether the pattern for cutting artificial hair generally according to shaver is sharp to assess shaver.At present
Conventional has two methods：
1st, as shown in figure 1, detection and the decision method of shaver sharpness is defined in GB GB/T 23132-2008：
Rated voltage is imposed to shaver, with a branch of artificial hair (nylon yarn) of 10 a diameter of 0.05mm～0.10mm, it is hand-held away from
From the position of pieces tip 4mm～6mm, being sequentially inserted into pieces in each test point carries out cut-out test, as shown in Figure 1.Count volume
Bent radical, by formula：
Curling radical rate=(curling total radical/shearing total radical) × 100%. are calculated, and can be cut off, be stopped showing without rolling
As, and less than 30%, curling radical rate thinks that shaver sharpness is good.
2nd, Nippon Standard JIS-C9614 then specifies：Three nylon yarns are pressed from both sides on the detector, 2～5mm is reserved, and is filled in
Shaver.Test position is chosen at five equally divided position of inner edge land length, every time test cutting three times.When shaver cuts 15 people
During work hair, the crimped length L of wherein 11 or more radicals can be switched to 0.4mm and following, just claim shaver sharp.For
The crimped length of nylon yarn, then mode is detected as shown in Figure 2.
Which kind of detection method no matter is taken, all there is no special testing equipment, be all to be installed to shave rotary shaver
On the whole machine of palpus knife, then according to corresponding detection method is detected that testing result receives extrinsic factor, such as motor between whole machine
The impact of difference, battery powered difference etc..And method 1 need to be classified according to curling situation to the nylon yarn after cut-out test
And counting, detection efficiency is low, and testing result is affected larger (for the judgement of classification critical point) by operator.
Method 2 specify that the judgement numerical value of nylon yarn crimped length, but need, using high-acruracy survey counting equipment, to detect
Cycle is longer, and cannot carry out the quick judgement of sharpness in production scene.
Utility model content
The purpose of this utility model is to solve above-mentioned technical problem, there is provided a kind of detection rotary shaver sharpness
Equipment, it is standby compact portable, can be conveniently fast, testing result does not receive interference from human factor, as a result accurately.
The technical solution adopted in the utility model is：A kind of equipment of detection rotary shaver sharpness, its feature exist
In by rotary shaver head fixing device, rotary shaver driving means, current sensing means, current transformation judgement calculating

Of the present utility model detected by above-mentioned equipment, is comprised the following steps that：By tested rotary shaver
It is installed in rotary shaver head fixing device, opens electric supply installation, shaver starts rotation, and ammeter obtains current circuit
Current value；Then the cutting of cut material, when cut material is cut, current sensing means are carried out using existing test sharpness method
Phase induced current is obtained, by current transformation, all data are judged that computing device is obtained and is stored, calculated, after cutting is completed, then by
Current transformation judges that computing device exports testing result according to onboard data and shown by result output device.
This utility model is being run well and is carrying out cutting cut material (usually nylon yarn) by detecting razor
When, the power consumed by motor carries out the judgement of sharpness, specifically detects the cutting cut material in motor circuit
When and idle running when electric current value changes size.This utility model is razor sharpness special inspecting equipment, and equipment is compact
It is portable, the detection of rotary shaver sharpness can be conveniently carried out, testing result is not affected by operator, by
This equipment just can export corresponding result of determination, simple and clear, and accuracy is high.
