Abstract
The utility model discloses a kind of hollow paper pushing rollers, it include the fixation core of cylindrical form, fixed core upper end is provided with axis hole, and fixed core upper end is provided with groove in a curved state, groove upper end is installed with the rubber wheel in circular arc convex, and rubber wheel and groove form a cavity.The utility model is installed with the rubber wheel in circular arc convex by groove upper end, and when rubber wheel is pressed on paper, the circular arc convex of rubber wheel becomes plane after being under pressure, so that the contact surface of rubber wheel and paper increases, to keep paper feeding reliably steady；Rubber wheel surface is provided with the anti-skid chequer in shape of threads, to prevent slipping phenomenon when paper feeding；The advantages of the utility model has novel design, structure simple, and paper feeding is reliably steady, prevents slipping phenomenon.
Description
Technical field
The utility model relates to feed roller technical field more particularly to a kind of hollow paper pushing rollers.
Background technique
Laser image formation device is widely used in office, and in image forming apparatus, it is desirable that it can by paper
It leans on and is smoothly sent into next paper transport device.With frustrating paper for a long time, paper-sheets rolling wheel serious wear, during there is frustrating paper
It skids, wrinkle phenomenon, causes the paper feeds failure such as paper jam.
Utility model content
The purpose of this utility model is that provide a kind of hollow paper pushing roller in view of the deficiencies of the prior art, this is hollow to be sent
Paper roller is novel in design, structure is simple, and paper feeding is reliably steady, prevents slipping phenomenon.
In order to achieve the above objectives, the utility model is achieved through the following technical solutions.
A kind of hollow paper pushing roller includes the fixation core of cylindrical form, and fixed core upper end is provided with axis hole, Gu
Determine core upper end and be provided with groove in a curved state, groove upper end is installed with the rubber wheel in circular arc convex, and rubber wheel with it is recessed
Slot forms a cavity.
Wherein, the axis hole is set to the central axis upper end of the fixed core.
Wherein, the fixed core upper end is provided with venthole, and is connected to the axis hole and cavity.
Wherein, rubber wheel surface upper end is provided with the anti-skid chequer in shape of threads.
The utility model has the following beneficial effects: a kind of hollow paper pushing roller described in the utility model, includes in cylinder
The fixation core of shape, fixed core upper end are provided with axis hole, and fixed core upper end is provided with groove in a curved state, on groove
End is installed with the rubber wheel in circular arc convex, and rubber wheel and groove form a cavity.The utility model is filled by groove upper end
Equipped with the rubber wheel for being in circular arc convex, when rubber wheel is pressed on paper, the circular arc convex of rubber wheel becomes flat after being under pressure
Face, so that the contact surface of rubber wheel and paper increases, to keep paper feeding reliably steady；It is provided with additionally by rubber wheel surface and is in
The anti-skid chequer of shape of threads, to prevent slipping phenomenon when paper feeding；The utility model has novel design, structure simple, and paper feeding can
By steady, the advantages of preventing slipping phenomenon.
Detailed description of the invention
The utility model is further detailed below with attached drawing, but the embodiment in attached drawing is not constituted pair
Any restrictions of the utility model.
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the cross-sectional view of the utility model.
Include in Fig. 1-2:
1 --- fixed core 11 --- axis hole
12 --- groove 13 --- ventholes
2 --- rubber wheels 21 --- cavity
22 --- anti-skid chequer.
Specific embodiment
The utility model is illustrated below with reference to specific embodiment.
As shown in Figure 1, a kind of hollow paper pushing roller, includes the fixation core 1 of cylindrical form, fixed 1 upper end of core
It is provided with axis hole 11, fixed 1 upper end of core is provided with groove 12 in a curved state, and 12 upper end of groove is installed in circular arc convex
Rubber wheel 2, and rubber wheel 2 and groove 12 form a cavity 21.
Preferred as the present embodiment, the axis hole 11 is set to the central axis upper end of the fixed core 1.
Further, 1 upper end of fixed core is provided with venthole 13, and is connected to the axis hole 11 and cavity 21.
Further, the 2 surface upper end of rubber wheel is provided with the anti-skid chequer 22 in shape of threads.
It need to further explain, the utility model is installed with the rubber wheel 2 in circular arc convex by 12 upper end of groove,
When rubber wheel 2 is pressed on paper, the circular arc convex of rubber wheel 2 becomes plane after being under pressure, so that rubber wheel 2 and paper connect
Contacting surface increases, to keep paper feeding reliably steady；2 surface of rubber wheel is provided with the anti-skid chequer 22 in shape of threads, thus
Slipping phenomenon when preventing paper feeding；The utility model has novel design, structure simple, and paper feeding is reliably steady, prevents slipping phenomenon
The advantages of.
The above content is only the preferred embodiment of the utility model, for those of ordinary skill in the art, according to this reality
With novel thought, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be construed as
Limitations of the present invention.
