Preferably, Kun shaft body two sides are respectively arranged with left connector and right connector, and are provided in the middle part of Kun shaft body
Hollow layer.
Preferably, the Kun shaft body outer diameter and Kun shaft sleeve inner diameter size are equal, and Kun shaft body and Kun shaft sleeve it
Between be slidably connected.
Preferably, the Kun axle sleeve drum outer wall is arranged with transmission gasket, and is driven gasket as rubber material, and driving pad
Piece surface is arcuate structure, and the transmission gasket is provided with 2, and is driven gasket about longitudinally asymmetric axis of Kun shaft sleeve or so pair
Claim setting, and bonds connection between Kun shaft sleeve and transmission gasket.
Preferably, the bolt is provided with 2, and bolt is symmetrical set about the longitudinally asymmetric axis of Kun shaft sleeve.
Compared with prior art, the utility model has the beneficial effects that the printer roller uses the Kun axis master of double-layer structure
Body and Kun shaft sleeve reduce the use cost of printer, are inter-connected via a bolt joint simultaneously convenient for replacing after the abrasion of Kun shaft sleeve
Kun shaft body and Kun shaft sleeve convenient for staff installation, reduce printer use cumbersome degree.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-4 is please referred to, the utility model provides a kind of technical solution: printer A4 upper roller, including Kun shaft body 2,
2 two sides of Kun shaft body are respectively arranged with left connector 1 and right connector 4, and hollow layer 3 is provided in the middle part of Kun shaft body 2, pass through middle part
The hollow layer 3 of setting reduces manufacturing cost and transmission power, and 2 outer wall of Kun shaft body is arranged with Kun shaft sleeve 5 and constitutes double-layer structure,
And 5 side of Kun shaft sleeve is provided with bolt 7,2 outer diameter of Kun shaft body and 5 inner diameter size of Kun shaft sleeve are equal, and 2 He of Kun shaft body
It is slidably connected between Kun shaft sleeve 5, Kun axis is connected with Kun shaft sleeve 5 convenient for staff by the Kun shaft body 2 being slidably connected
Main body 2 and Kun shaft sleeve 5,5 outer wall of Kun shaft sleeve are arranged with transmission gasket 6, and being driven gasket 6 is rubber material, and is driven
6 surface of gasket is arcuate structure, and transmission gasket 6 is provided with 2, and is driven gasket 6 about longitudinally asymmetric axis of Kun shaft sleeve 5 or so
It is symmetrical arranged, and bonds connection between Kun shaft sleeve 5 and transmission gasket 6, Kun axis is increased by the transmission gasket 6 of rubber material
Frictional force between main body 2 and paper, to guarantee the transmission efficiency of paper, bolt 7 is provided with 2, and bolt 7 is about Kun axis
The longitudinally asymmetric axis of sleeve 5 is symmetrical set, by the bolt 7 that is symmetrical set improve Kun shaft body 2 and Kun shaft sleeve 5 it
Between firmness of the connection, prevent the opposite sliding of Kun shaft body 2 and Kun shaft sleeve 5 from influencing the rotational efficienty of paper, bolt 7 passes through respectively
Kun shaft body 2 and Kun shaft sleeve 5 are worn, and Kun shaft body 2 and Kun shaft sleeve 5 are connected with each other by bolt 7, using double-layer structure
Kun shaft body 2 and Kun shaft sleeve 5 are replaced after wearing convenient for Kun shaft sleeve 5, reduce the use cost of printer, while passing through spiral shell
The Kun shaft body 2 interconnected of bolt 7 and Kun shaft sleeve 5 reduce printer and use cumbersome degree convenient for staff's installation.
Working principle: when using the printer roller, first check whether each components connect intact in printer, check
After staff start printer Kun shaft body 2 and the rotation of Kun shaft sleeve 5 driven by left connector 1 and right connector 4, pass through
The rotation of Kun shaft body 2 and Kun shaft sleeve 5 is so that Kun shaft body 2 and Kun shaft sleeve 5 drive paper to slowly enter in printer, together
When Kun shaft body 2 and 5 rotary course of Kun shaft sleeve in gasket 6 is driven by the rubber material of 5 outer wall of Kun shaft sleeve bonding connection
Increase the firmness of the connection of Kun shaft sleeve 5 and paper to improve the transmission efficiency of paper, while by setting in the middle part of Kun shaft body 2
The hollow layer 3 set reduces the weight of Kun shaft body 2 to reduce the transmission power of printer, reduce the use of printer at
This, printer long-time use after due to the constantly friction of paper and Kun shaft sleeve 5 so that 5 surface damage of Kun shaft sleeve, work at this time
Make personnel and be separated from each other the left connector 1 of Kun shaft body 2 and right connector 4 with printer, then rotates bolt 7 and make bolt 7 and Kun
Shaft body 2 and Kun shaft sleeve 5 are separated from each other, and staff pulls Kun shaft body 2 to make Kun shaft body 2 after bolt 7 is opened
It is separated from each other with Kun shaft sleeve 5, then impaired Kun shaft sleeve 5 is replaced, staff after Kun shaft sleeve 5 is replaced
Again bolt 7 and Kun shaft body 2 and Kun shaft sleeve 5 are connected with each other, Kun shaft body 2 and Kun shaft sleeve 5 is fixed, prevented
Kun shaft body 2 and the opposite sliding of Kun shaft sleeve 5 influence paper transmission efficiency, and here it is the use processes of the printer roller.
Although the utility model is described in detail with reference to the foregoing embodiments, come for those skilled in the art
Say, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic into
Row equivalent replacement, within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should all
It is included within the scope of protection of this utility model.
