Type wheel and inker
Technical field
The present invention relates to the inker technical field, particularly relate to a kind of type wheel and inker.
Background technology
At present, after tubing is manufactured moulding, often need on tubing, mark any one or the much information such as its model, size, manufacturer's information or material, to realize the functions such as differentiation between tubing.On the tubing information labeling, often adopt the tubing inker to realize.
As shown in Figure 1, it is a kind of structural representation of existing tubing inker.As shown in the figure, this inker comprises support 110, is arranged at the type wheel 120 on described support 110, and the guide wheel 130 that is arranged at described type wheel below.Wherein guide wheel 130 is be used to supporting tubing, and type wheel 120 or guide wheel 130 can be with respect to the other side up and down, move left and right, thereby make type wheel 120 or guide wheel 130 fix and stamp information needed thereon by tubing.
And in the long-time use procedure of inker, the printing ink on type wheel surface can be penetrated in the gap that contacts between type wheel wheel body and lettering wheel shaft, refer to Fig. 2, the wheel body 210 of type wheel is arranged on the top B point of wheel shaft 220 and is easy to be stained with printing ink, process along with the time, after printing ink parches and solidifying, the wheel body 210 of type wheel just can be sticked together with wheel shaft 220, make the type wheel wheel body be difficult to unload from wheel shaft, and then cause the dismounting difficulty when dismounting and change or cleaning type wheel, and easily damage type wheel.
Summary of the invention
In view of this, the invention provides a kind of type wheel and inker, be used to the printing ink that solves type wheel, pollute the wheel body that causes type wheel and be difficult to the technical problems such as dismounting and easy damage.
The invention provides a kind of type wheel, it comprises: wheel body, wheel shaft, top cap; Wherein, described wheel body, be sheathed on described wheel shaft; The top cap, be sheathed on described wheel shaft, and with described wheel body butt.
Further, described top cap is by thread and described wheel shaft engagement socket.
The present invention also provides a kind of inker, its type wheel as above.
In sum, type wheel provided by the present invention and inker, when the wheel body of dismounting type wheel, only need to rotate a top cap and dismantle wheel body, avoided the impact of the type wheel of printing ink, reduced in the unloading process damage to type wheel.
The accompanying drawing explanation
Figure 1 shows that a kind of structural representation of existing tubing inker;
Figure 2 shows that a kind of schematic cross-section of existing type wheel;
Figure 3 shows that the schematic cross-section of a kind of type wheel that one embodiment of the invention provides;
Figure 4 shows that one embodiment of the invention also provides a kind of inker.
The specific embodiment
For purpose of the present invention, feature are become apparent, below in conjunction with accompanying drawing, the specific embodiment of the present invention is further described.
Consider that the type wheel of prior art tubing lettering is in long-time use procedure, printing ink on type wheel can pollute the contact-making surface between wheel body and wheel shaft, solid along with printing ink, and then wheel body and wheel shaft firmly are sticked together mutually, cause when the dismounting type wheel, cause wheel body dismounting difficulty, and easily damage type wheel.The wheel body of the improved type wheel that the present invention proposes and the syndeton between wheel shaft, thus the impact of typing printing ink on type wheel avoided, reduced the damage of type wheel at unloading process.
Please refer to Fig. 3, the structural representation of a kind of type wheel that it provides for one embodiment of the invention.As shown in the figure, this type wheel comprises: wheel body 310, wheel shaft 320, top cap 330; Wherein, described wheel body 310, be sheathed on described wheel shaft 320; Top cap 330, be sheathed on described wheel shaft 320, and with described wheel body 310 butts.Utilize above-mentioned type wheel in long-time use procedure, contact-making surface and solid wheel body 310 and the top cap 330 of making that printing ink pollutes between the top cap 330 on wheel body 310 and sheathed and wheel shaft 320 are sticked together, when dismounting type wheel wheel body, only need to rotate top cap 330, just can produce an axial power makes wheel body 310 break away from smoothly wheel shaft 320, thereby broken away from the harm of printing ink to type wheel, reduced the damage in the type wheel unloading process.
In embodiments of the present invention, described top cap 330 is by thread and the 320 engagement sockets of described wheel shaft, thereby make top cap 330 in rotation process, intermeshing thread between dependence and wheel shaft 320, can be that top cap 330 produces an axial propulsive force, and then promote smoothly wheel body 310 and wheel shaft 320 disengagings.
Please refer to Fig. 4, the embodiment of the present invention also provides a kind of inker, comprises support 410, is arranged at the type wheel 420 on described support 410, and the guide wheel 430 that is arranged at described type wheel below.Wherein type wheel 420, for the lettering body, has described any type wheel structure of above embodiment.
In sum, the type wheel that the embodiment of the present invention provides and inker, when the wheel body of dismounting type wheel, only need to rotate a top cap and dismantle wheel body, avoided the impact of the type wheel of printing ink, reduced in the unloading process damage to type wheel.
Although the present invention discloses as above with preferred embodiment; so it is not in order to limit the present invention; under any, in technical field, have and usually know the knowledgeable; without departing from the spirit and scope of the present invention; when being used for a variety of modifications and variations, so protection scope of the present invention is as the criterion when looking claims person of defining.
