A kind of dismountable printer paper-sheets rolling wheel
Technical field:
The present invention relates to the technical field of printer accessory, more specifically to a kind of dismountable printer pickup
Wheel.
Background technology:
Paper-sheets rolling wheel is a kind of important composition component in printer, and existing paper-sheets rolling wheel generally has shaft and sleeve in shaft
Upper rubber wheels composition, general rubber wheels prevent from sending out between rubber wheels and shaft by being pasted and fixed in shaft
It is raw to relatively rotate, and the easy aging of rubber wheels, pasting fixed rubber wheels is not easy to remove from shaft, so as to general right
Entire paper-sheets rolling wheel is replaced, but the shaft of its general paper-sheets rolling wheel still can use, and integrally scrap, cause the wasting of resources.
The content of the invention:
The purpose of the present invention and provides a kind of dismountable printer paper-sheets rolling wheel aiming at the deficiency of the prior art,
It can be convenient for the rubber wheels of aging on paper-sheets rolling wheel to replace, and improve the utilization rate of resource.
To achieve the above object, the technical solution adopted by the present invention is as follows:
A kind of dismountable printer paper-sheets rolling wheel, including the first connecting shaft, one end of the first connecting shaft forms gear, tooth
Fulcrum is formed on wheel, the other end of the first connecting shaft forms the first block plate, formed on the first block plate and the first connecting shaft
Concentric mandrel if forming arterial highway dovetail groove on the outer wall of mandrel, forms on the mandrel and is inserted with rubber foreign steamer, rubber
If forming the strip of arterial highway swallow-tail form on glue foreign steamer inner wall, strip is plugged in the dovetail groove of mandrel;The side of the mandrel
Form the rectangular opening through the side end face of fulcrum on face, against there is the second block plate on the side end face of mandrel, the one of the second block plate
Rectangle cutting is formed on side end face, rectangle cutting is plugged in the rectangular opening of mandrel and forms stud, and stud exposes fulcrum
Side end face be bolted with nut, the second connecting shaft, the side end face of the second connecting shaft are formed on another side end face of the second block plate
On form the counterbore of regular hexagon.
Preferably, the length of the rubber foreign steamer is equal to the length of mandrel.
Preferably, if forming arterial highway raised line on the outer wall of the rubber foreign steamer, raised line is around the central axis of rubber foreign steamer
It is uniformly distributed in a ring, the strip is uniformly distributed in a ring around the central axis of rubber foreign steamer.
Preferably, the diameter of first connecting shaft is equal to the diameter of the second connecting shaft.
Preferably, the nut uses round nut, and the diameter of nut is less than the diameter of fulcrum, is molded on the outer wall of nut
There are several notches.
Preferably, on second block plate rectangle cutting length be less than mandrel length.
The beneficial effects of the present invention are:During its paper-sheets rolling wheel rubber wheel aging used, it can be dismantled, be conveniently replaceable rubber
Rubber tire, without being scrapped to the shaft with gear on paper-sheets rolling wheel, shaft can still provide for using, and effectively improve resource
Utilization rate.

Specific embodiment:
Embodiment:As shown in Fig. 1 to 4, a kind of dismountable printer paper-sheets rolling wheel, including the first connecting shaft 1, the first connection
One end of axis 1 forms gear 11, and fulcrum 12 is formed on gear 11, and the other end of the first connecting shaft 1 forms the first block plate
13, the mandrel 14 concentric with the first connecting shaft 1 is formed on the first block plate 13, if forming arterial highway dovetail on the outer wall of mandrel 14
Slot 141 forms on the mandrel 14 and is inserted with rubber foreign steamer 2, if forming arterial highway swallow-tail form on 2 inner wall of rubber foreign steamer
Strip 21, strip 21 are plugged in the dovetail groove 141 of mandrel 14;It is formed on the side end face of the mandrel 14 through fulcrum 12
The rectangular opening 15 of side end face against there is the second block plate 3 on the side end face of mandrel 14, forms on a side end face of the second block plate 3
Rectangle cutting 32, rectangle cutting 32 are plugged in the rectangular opening 15 of mandrel 14 and form stud 33, and stud 33 exposes fulcrum 12
Side end face be bolted with nut 4, the second connecting shaft 31 is formed on another side end face of the second block plate 3, the second connecting shaft 31
The counterbore 311 of regular hexagon is formed on side end face.
Preferably, the length of the rubber foreign steamer 2 is equal to the length of mandrel 14.
Preferably, if forming arterial highway raised line 22 on the outer wall of the rubber foreign steamer 2, raised line 22 is in rubber foreign steamer 2
Mandrel line is uniformly distributed in a ring, and the strip 21 is uniformly distributed in a ring around the central axis of rubber foreign steamer 2.
Preferably, the diameter of first connecting shaft 1 is equal to the diameter of the second connecting shaft 31.
Preferably, the nut 4 uses round nut, and the diameter of nut 4 is less than the diameter of fulcrum 12, the outer wall of nut 4
On form several notches.
Preferably, on second block plate 3 rectangle cutting 32 length be less than mandrel 14 length.
Preferably, on the supporting rod 131 notch 132 depth be more than idler wheel 14 diameter, the first connecting shaft 1, second
Block plate 3 and nut 4 use nylon material.
Operation principle:For the present invention for dismountable printer paper-sheets rolling wheel, paper-sheets rolling wheel uses fabricated structure, outside rubber
Wheel 2 then works as rubber using the structure realization to your keyway and the connection before shaft (the first connecting shaft 1 and the second connecting shaft 31)
During 2 aging of foreign steamer, the first connecting shaft 1 and the second detachably separation of connecting shaft 31 are replaced rubber foreign steamer 2, the first connection
1 and second connecting shaft 31 of axis still can be used, and improve the utilization rate of resource.
The embodiment is to be illustrated the present invention, and is not intended to limit the present invention.Any those skilled in the art
It can modify under the spirit and scope without prejudice to the present invention to the embodiment, therefore the rights protection model of the present invention
