Fig. 2 is the structural representation of the paper-feeding mechanism according to the utility model one embodiment.As in figure 2 it is shown, this practicality is new
Type provides a kind of paper-feeding mechanism, and paper-feeding mechanism includes that supporting mechanism 1 and paper will most testing agencies 2.Wherein, supporting mechanism includes side
Wall 11 and supporting part, supporting part is used for supporting roll web 3, and sidewall is connected with supporting part and is oppositely arranged with the end face of roll web；
Most testing agency 2 is arranged on the sidewall 11 of supporting mechanism 1 by paper, and for detecting the surplus paper amount of roll web 3, paper will detect to the greatest extent machine
Structure 2 includes that photoelectric sensor 21, photoelectric sensor 21 include optical generator 211 and optical receiver 212, when the surplus paper of roll web 3
Amount more than setting value time, optical generator 211 with in optical receiver 212 two at least one relative with the end face of roll web 3；When
When the surplus paper amount of roll web 3 is less than or equal to setting value, optical generator 211 and optical receiver 212 both of which and roll web 3
End face staggers, and along the core cylinder axis projection of roll web, optical generator and optical receiver are respectively positioned on the outside of core cylinder.Wherein, light
Generator 211 can be the light-emitting component such as light emitting diode or laser diode, optical receiver 212 can be photodiode or
The photoelectric cells such as phototriode.
The paper of paper-feeding mechanism that the utility model provide is described below by the course of work of most testing agency.
As it is shown on figure 3, when the surplus paper amount of roll web 3 is more than setting value, i.e. the paper of roll web is not by time to the greatest extent, and light occurs
Device 211 with in optical receiver 212 two at least one relative with the end face of roll web 3, optical generator 211 emits beam irradiation
On the end face of roll web 3, through the end face reflection of roll web 3 to optical receiver 212, now, it is anti-that optical receiver 212 receives
Penetrating light intensity high, optical receiver 212 exports the first magnitude of voltage；Along with the paper on core cylinder 31 gradually decreases, when surplus paper amount is little
When equal to setting value, when i.e. the paper of roll web will be used up, as shown in Figure 4, optical generator 211 and optical receiver 212 are equal
Sounding, the light that optical generator 211 sends diffusing reflection within holding paper space, irreflexive light only has on a small quantity by optical receiver
212 receive, and the light intensity that therefore optical receiver 212 receives is the lowest, and now, optical receiver 212 exports the second magnitude of voltage.
Owing to, the first magnitude of voltage and the second magnitude of voltage difference are obvious, therefore can select be positioned at the first magnitude of voltage and the second magnitude of voltage it
Between and with the numerical value of the first magnitude of voltage and the second magnitude of voltage significant difference as threshold value.The paper that the utility model provides will inspection to the greatest extent
Survey mechanism, even if in use being beated by roll web, the interference photoelectric sensor of the influence factor such as extraneous light change
The magnitude of voltage of output is discrete, it is also possible to judge whether the paper of roll web will be used up timely and accurately.
In the present embodiment, the installation site of photoelectric sensor 21 is arranged to: as it is shown on figure 3, when the external diameter of roll web 3
More than when setting external diameter, the surplus paper amount of roll web 3 is more than setting value, optical generator 211 and optical receiver 212 by sidewall 11
Opening all relative with the end face of roll web 3；When the external diameter of roll web 3 is less than or equal to setting external diameter, the surplus paper on core cylinder 31
Amount staggers, with supporting mechanism less than or equal to the end face of setting value, optical generator 211 and optical receiver 212 both of which with roll web 3
Appearance paper space relative.Wherein, the surplus paper amount of roll web 3 can be according to the external diameter of roll web 3, the external diameter of core cylinder 31, and paper
THICKNESS CALCULATION draw.
Usually, the core cylinder 31 of roll web 3 has certain wall thickness, and core cylinder 31 has inner and outer wall, therefore, and core cylinder 31
Being projected as annulus on sidewall 11, wherein, the inwall of core cylinder 31 is projected as the first circle, the outer wall of core cylinder 31 on sidewall 11
On sidewall 11 be projected as second circle, second circle radius and first circle radius between the wall thickness that difference is core cylinder 31,
It is therefore preferred that optical generator 211 and optical receiver 212 are arranged on the outside of the outer wall of core cylinder 31 projection on sidewall 11,
Optical generator 211 the most just can be avoided with in optical receiver 212 any one is relative with the inside of core cylinder 31.
Preferably, optical generator 211 and a top being positioned at another in optical receiver 212 two.Need explanation
, in description of the present utility model, top can be surface, it is also possible to be oblique upper, so long as not being in same water
Flat height, the most all meets optical generator 211 and a top being positioned at another in optical receiver 212 two.
Specifically, see Fig. 4, when the paper of roll web 3 will be used up, and the core cylinder 31 of roll web 3 moves closer to diapire 12
Time, the optical generator 211 of photoelectric sensor 21 and optical receiver 212 be respectively positioned on the top of core cylinder 31, and with the end face of roll web 3
Stagger.
The paper of paper-feeding mechanism that the utility model provide is described below by the course of work of most testing agency.
As it is shown on figure 3, when the surplus paper amount of roll web 3 is more than setting value, i.e. during the paper abundance of roll web, optical generator
211 is all relative with the end face of roll web 3 with optical receiver 212, and optical generator 211 emits beam and is radiated at the end face of roll web 3
On, through the end face reflection of roll web 3 to optical receiver 212, now, the reflection light intensity that optical receiver 212 receives is high, light
Receiver 212 exports the first magnitude of voltage；Along with the paper on core cylinder 31 gradually decreases, when surplus paper amount is less than or equal to setting value,
When i.e. the paper of roll web will be used up, as shown in Figure 4, optical generator 211 and the equal sounding of optical receiver 212, optical generator 211
The light sent diffusing reflection within holding paper space, irreflexive light is only received by optical receiver 212 on a small quantity, therefore light-receiving
The light intensity that device 212 receives is the lowest, and now, optical receiver 212 exports the second magnitude of voltage.Due to, the first magnitude of voltage and
Second magnitude of voltage difference is obvious, therefore can select between the first magnitude of voltage and the second magnitude of voltage and with the first magnitude of voltage
And second the numerical value of magnitude of voltage significant difference as threshold value.The paper that the utility model provides is by testing agency to the greatest extent, in the process of use
Beated by roll web in even if, magnitude of voltage that the influence factor such as extraneous light change is disturbed photoelectric sensor to export discrete,
Can also judge whether the paper of roll web will be used up timely and accurately.
Fig. 5 is the structural side view of the paper-feeding mechanism according to another embodiment of the utility model.As it is shown in figure 5, supporting part
