Inker guide wheel and inker
Technical field
The present invention relates to the inker technical field, particularly relate to a kind of inker guide wheel and inker.
Background technology
At present, after tubing is made moulding, often need to be at any one or the much information such as its model of tubing mark, size, manufacturer's information or material, to realize the functions such as differentiation between the 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 the described support, and the guide wheel 130 that is arranged at described type wheel below.Wherein guide wheel 130 is used for supporting tubing, and type wheel 120 or guide wheel 130 can with respect to about the other side, move left and right, thereby so that type wheel 120 or guide wheel 130 fix and stamp information needed thereon with tubing.
Please refer to Fig. 2, it is a kind of schematic cross-section of existing guide wheel, and as shown in the figure, guided wheel slot 210 cross sections of existing guide wheel are U-shaped, and the tubing 10 of printed information is out-of-date from guide wheel, and lettering face and guide wheel contact friction may cause font to be damaged.
Summary of the invention
In view of this, the invention provides a kind of inker guide wheel and inker, be used for solving tubing lettering face and contact the technical problem that causes font to be damaged with guide wheel.
The invention provides a kind of inker guide wheel, it comprises the guide wheel main body, the described outward flange of stating the guide wheel main body has the guided wheel slot of the depression of guide wheel body center position, described guided wheel slot is used for supporting tubing, and described guided wheel slot does not contact with described tubing the part below the strong point of described tubing.
Further, the cross section of described guided wheel slot is V-type.
Further, the cross section of described guided wheel slot is inverted trapezoidal, and the described strong point is positioned on the described trapezoidal side.
The present invention also provides a kind of inker, its aforesaid inker guide wheel.
In sum, guide wheel provided by the present invention and inker can firm support tubing, and partly do not contact with the lettering of tubing, thereby avoided the wearing and tearing of institute's lettering body.

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.
The contact friction of considering prior art tubing lettering face and guided wheel slot may cause font to be damaged, and the application proposes a kind of improved guided wheel slot structure.Please refer to Fig. 3, the structural representation of a kind of guide wheel that it provides for one embodiment of the invention.As shown in the figure, this guide wheel comprises guide wheel main body 310, and the outward flange of described guide wheel main body has the guided wheel slot 320 of guide wheel body center position depression.This guided wheel slot 320 is used for supporting tubing 10, and the following part of the strong point of 320 pairs of tubing 10 of guided wheel slot does not contact with tubing.
When tubing 10 was placed the guided wheel slot 210 of existing U-shaped structure, the lettering face meeting of tubing and the contact friction between the guide wheel caused the wearing and tearing of institute's lettering body easily.And when tubing 10 placed the guided wheel slot 320 that present embodiment provides, the following part of the strong point of 320 pairs of tubing 10 of guided wheel slot can not contact with tubing, thereby has avoided the wearing and tearing of institute's lettering body.In addition, existing U-shaped guided wheel slot is single-point support to tubing, supports unstablely, can cause that tubing moves, and causes print position not reach the anticipation requirement, and also can because of mobile and cause friction, cause institute's lettering body to wear and tear; And 320 pairs of tubing 10 of the guided wheel slot of present embodiment support for two point, and because Action of Gravity Field, tubing 10 can be fastened in wherein, has avoided the problems such as print position skew and font wearing and tearing.
In one embodiment, the cross section of described guided wheel slot 320 comprises two symmetrical line segments 321,322, and the distance between described two line segments 321,322 is dwindled gradually.Thereby when tubing 10 places this guided wheel slot 320, guided wheel slot 320 sidewalls and the tangent support of tubing, thus guarantee the tubing firm support in this guided wheel slot 320, avoid institute's lettering body wearing and tearing.
In one implementation, as shown in Figure 4, the distance between the symmetrical line segment 321,322 in guided wheel slot 320 cross sections is dwindled gradually until intersect, thereby consists of the V-type cross section.So, guide wheel is made simple, saves cost of manufacture.
In another kind of implementation, as shown in Figure 5, the cross section of guided wheel slot 320 also comprises and symmetrical line segment 321,322 the 3rd limits 323 of intersecting, and the distance between described two line segments 321 in 322 is dwindled gradually until intersect with described the 3rd limit 323.Described the 3rd limit 323 can be that straight line also can be curve, and when it was straight line, the cross section of described guided wheel slot was inverted trapezoidal, and the strong point of 320 pairs of tubing 10 of guided wheel slot is positioned at two sides of inverted trapezoidal, namely on the line segment 321,322.
Please refer to Fig. 6, the embodiment of the invention also provides a kind of inker, comprises support 610, is arranged at the type wheel 620 on the described support 610, and the guide wheel 630 that is arranged at described type wheel below.Wherein guide wheel 630 is used for supporting tubing, and has described any Guiding wheel structure of above embodiment.
In sum, the guide wheel that the embodiment of the invention provides and inker can firm support tubing, and partly do not contact with the lettering of tubing, thereby avoided the wearing and tearing of institute's lettering body.
Although the present invention discloses as above with preferred embodiment; so it is not to limit the present invention; have in the technical field under any and usually know the knowledgeable; without departing from the spirit and scope of the present invention; when can 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.
