Utility model content
The defects of in order to overcome prior art, technical problem to be solved in the utility model are that proposing that one kind has divides
The roll shaft of paper function, by the shape for reasonably designing rubber roll so that roll shaft has to stack paper, film or other analogs
Carry out the function of paging.
To use following technical scheme up to this purpose, the utility model：
A kind of roll shaft with paper separation function provided by the utility model, including shaft core and rubber roll, the rubber roll are fixed on
In the shaft core, the separation ridge for paper separation is provided with the rubber roll.
In the preferable embodiment of the utility model, the rubber roll includes first kind rubber roll and the second class rubber roll, described
First kind rubber roll, the second class rubber roll are each attached in the shaft core, on the first kind rubber roll, the second class rubber roll
It is provided with separation ridge.
In the preferable embodiment of the utility model, two first kind rubber rolls are located at two the second class rubber rolls
Between, the length of the first kind rubber roll is less than the length of the second class rubber roll.
In the preferable embodiment of the utility model, the separation ridge is configured to horizontal separation ridge, the horizontal separation
The bearing of trend of ridge is consistent with the centerline direction of the shaft core, and gap is left between two adjacent separation ridges.
In the preferable embodiment of the utility model, the separation ridge is configured to spiral separation ridge, is set in the shaft core
There is round tube hole, two round tube holes are located at the both sides of the spiral separation ridge.
In the preferable embodiment of the utility model, the shaft core include be used for install the rubber roll the first shaft core,
And it is fixed on second shaft core at two the first shaft core both ends.
In the preferable embodiment of the utility model, it is provided with least one second shaft core solid for installing
The limiting stand of determined power input, the side of the limiting stand are provided with escape.
The beneficial effects of the utility model are：
Roll shaft provided by the utility model with paper separation function, there is provided the separation ridge separated for paper, separation ridge
Stack paper can be separated.By the shape for reasonably setting separation ridge so that the power for being applied to stack paper is suddenly big
Suddenly small, having to open has relaxation, when such stack paper is in relaxed state, it is easy to which the rubber roll gradually compressed is taken away, so as to realize
Paper separation function.

Embodiment
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by embodiment.
Embodiment one
As shown in Figures 1 and 2, a kind of roll shaft with paper separation function provided in embodiment one, including shaft core 1 and rubber roll
2, rubber roll 2 is fixed in shaft core 1, and separation ridge 3 is provided with rubber roll 2, and separation ridge 3 is used to separate stack paper, separation
It is equal and have certain gap that ridge 3 is uniformly arranged in the distance between rubber roll 2, two neighboring separation ridge 3.
In order to strengthen the stability during separation, further, rubber roll 2 includes the class rubber roll of first kind rubber roll 21 and second
22, first kind rubber roll 21, the second class rubber roll 22 are each attached in shaft core 1, are all provided with first kind rubber roll 21, the second class rubber roll 22
It is equipped with separation ridge 3.Due to being both provided with separation ridge 3, and two first kind rubber rolls on the class rubber roll 22 of first kind rubber roll 21 and second
21 between two the second class rubber rolls 22, namely two first kind rubber rolls 21 are symmetrical arranged with two the second class rubber rolls 22.
The quantity of rubber roll increases and rubber roll is symmetrical arranged the stability and reliability being added significantly to during separation.Further preferably
, the length of first kind rubber roll 21 is less than the length of the second class rubber roll 22, and this mainly considers the separation power of diverse location needs not
Too, this setup can reach good separation effect.
As shown in Fig. 2 in order to strengthen the separation effect of roll shaft, further, separation ridge 3 is configured to horizontal separation ridge, horizontal
It is consistent with the centerline direction of shaft core 1 to the bearing of trend of separation ridge, leave gap between two adjacent separation ridges 3.Due to
Separation ridge 3 and the alternating action in gap are in stack paper, and the power that this allows for being applied to stack paper is suddenly big or suddenly small, and having to open has
Relax, when stack paper is in relaxed state, it is easy to taken away by the rubber roll that roll shaft rotation generation transverse component gradually compresses, it is real
Existing paper separation function.
As shown in figure 1, the installation and fixation of shaft core 1 for convenience, further, shaft core 1 include being used to install rubber roll 2
First shaft core 12 and the second shaft core 13 for being fixed on two both ends of the first shaft core 12.Set in the second at least one shaft core 13
