Brief description of the drawings
Fig. 1 is the structure diagram of anti-sticking feeding roller provided by the utility model.
Fig. 2 is the front view of anti-sticking feeding roller provided by the utility model.
Fig. 3 is the sectional view in A-A directions in Fig. 1.
Embodiment
The utility model provides a kind of anti-sticking feeding roller, to make the purpose of this utility model, technical solution and effect more
Clear, clear and definite, the utility model is further described in the embodiment that develops simultaneously referring to the drawings.It should be appreciated that this place is retouched
The specific embodiment stated only to explain the utility model, is not used to limit the utility model.
Please refer to Fig.1-3, a kind of anti-sticking feeding roller, including feeding roller body, and it is arranged at feeding roller body both ends
Roll shaft 11, is uniformly provided with some ventholes 21 on the side wall of feeding roller body；Feeding roller body interior is provided with air flue 12, gas
Road 12 is connected to the air inlet 13 for being located therein a roll shaft end face；The venthole 21 is connected with air flue 12.It is passed through from air inlet
After gases at high pressure, gas will be sprayed from the venthole on periphery, can effectively prevent paper adhesion in feeding roller circumference
On face.Preferably, the diameter of venthole is not more than 2mm, to prevent feeding roller surface is excessively coarse and damages paper surface.
Specifically, seeing Fig. 1,3, the feeding roller body includes the interior roll body 1 being wholely set with roll shaft 11, and rotatably
Ground is sheathed on the outer barrel 2 on interior roll body periphery；Interior roll body 1 is fixed；The air flue 12 is arranged in interior roll body 1, institute
Venthole 21 is stated to be arranged on outer barrel 2；The communicating passage for connecting air flue 12 and downside venthole is provided with interior roll body 1
14.In this way, only there is a gas ejection in downside close to the venthole of paper 90, the impulse force bigger of gas, more can guarantee that paper with it is outer
Cylinder reliable separation.Herein, interior roll body is fixed on the conveyor line by roll shaft, and the cross section of roll shaft is preferably polygon, fixed
When can conveniently carry out it is circumferentially positioned.
Further, Fig. 1,3 are seen, the communicating passage 14 is along interior 1 length direction of roll body extends, fan-shaped cross section
Groove；The opening down setting of groove, the upper end of groove are connected with air flue 12.
The gas sprayed in order to prevent blows afloat the paper for being just sent to feeding roller, and the opening of communicating passage 14 is transported towards paper 90
Dynamic direction is obliquely installed, as shown in figure 3, the direction of arrow is the direction of motion of paper in figure.
In the present embodiment, Fig. 3 is seen, in the cross section of communicating passage 14, the first straight flange 141 is set straight down, and second
The angle b in 142 and first straight flange 141 of straight flange along sheet movement direction is 30 °~50 °.Preferably, angle b is 45 °, paper
Separating effect it is optimal.Paper by rear, blown afloat by its rear end in order to prevent, can set a baffle 91 in blowing direction downstream,
