Abstract
The utility model discloses a kind of printer feeding-in roll, comprise roll shaft and be equally distributed on the running roller on roll shaft, on roll shaft, the position of corresponding running roller is provided with annular protrusion, and running roller is placed on the first annular protrusion, and the middle part in running roller inwall circumferentially face is provided with the annular groove mated with annular protrusion.The utility model compared to existing technology, position corresponding with running roller on roll shaft is provided with annular protrusion, running roller inwall arranges the annular groove coordinated with annular protrusion accordingly, by the screens between annular protrusion and annular groove, the situation preventing running roller to slide along roll shaft direction of axis line on roll shaft occurs.And the possibility that the anti-skidding striped that between annular protrusion and annular groove, contact surface is arranged prevents the circumference between running roller and roll shaft to slide.Therefore the steadiness of running roller of the present utility model is better, more durable.
Description
Technical field
The utility model relates to printer apparatus, particularly a kind of printer feeding-in roll.
Background technology
A kind of printer feeding-in roll, as realizing paper pushing part, has important function to the stable of printer routine work, the height of paper feeding efficiency, determines the efficiency that printer runs.Existing feeding-in roll is sheathed some barrel-type roller wheel compositions on roll shaft, and running roller is set in qually spaced on roll shaft.Existing running roller is one end that rubber tube is cut into, running roller is enclosed within roll shaft, between fixed by crosslinking agent, but because working environment is often in the environment unexpectedly replaced, will slide between running roller and roll shaft so of long duration, thus affect the stability of paper feeding, easy paperboard, reduce printing effect and effect.
Utility model content
In order to overcome above-mentioned defect, the utility model provides a kind of printer feeding-in roll, the annular protrusion that roll shaft is provided with, and it is strong that running roller is set in steadiness, not easily slides, and running roller thinner thickness, therefore save material cost.
The utility model is achieved through the following technical solutions:
A kind of printer feeding-in roll, comprise roll shaft and be equally distributed on the running roller on roll shaft, on roll shaft, the position of corresponding running roller is provided with annular protrusion, and running roller is placed on the first annular protrusion, and the middle part in running roller inwall circumferentially face is provided with the annular groove mated with annular protrusion.
Fixed by crosslinking agent between described running roller and the first annular protrusion.
The outer surface of described annular protrusion and the bottom surface of annular groove are equipped with anti-skidding striped, and described anti-skidding stripe direction is parallel with roll shaft direction of axis line.
Described running roller is rubber.
The utility model compared to existing technology, position corresponding with running roller on roll shaft is provided with annular protrusion, running roller inwall arranges the annular groove coordinated with annular protrusion accordingly, by the screens between annular protrusion and annular groove, the situation preventing running roller to slide along roll shaft direction of axis line on roll shaft occurs.And the possibility that the anti-skidding striped that between annular protrusion and annular groove, contact surface is arranged prevents the circumference between running roller and roll shaft to slide.Therefore the steadiness of running roller of the present utility model is better, more durable.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is A-A generalized section in Fig. 1.
Fig. 3 is B-B generalized section in Fig. 1.
Detailed description of the invention
As shown in Figure 1, the running roller 2 that the utility model comprises roll shaft 1 and is equally distributed on roll shaft 1, in the present embodiment, running roller 2 is rubber.On roll shaft 1, the position of corresponding running roller 2 is provided with annular protrusion 3, and running roller 2 is placed on the first annular protrusion 3, and the middle part in running roller 2 inwall circumferentially face is provided with the annular groove 4 mated with annular protrusion 3.
Fixed by crosslinking agent between described running roller 2 and annular protrusion 3.
In order to increase the frictional force between running roller 2 and roll shaft 1, be equipped with anti-skidding striped (not shown) at the outer surface of annular protrusion 3 and the bottom surface of annular groove 4, described anti-skidding stripe direction is parallel with the direction of axis line of roll shaft 1.
