Abstract
The utility model relates to a paper feeding mechanism of a printer, comprising a body and a paper feeding roller, wherein the body is provided with a first shaft hole and a second shaft hole which are oppositely arranged; the paper feeding roller is provided with a first end and a second end, the second end is arranged in the second shaft hole in a penetration mode, and the first end is sheathed with a movable first shaft sleeve; and when the first end is arranged in the first shaft hole in a penetration mode, the first shaft sleeve is positioned between the first end and the first shaft hole. As the first shaft sleeve is movably sheathed on the paper feeding roller instead of being fixed in the first shaft hole, a larger moving space exists between the first end of the paper feeding roller and the first shaft hole during dismounting, thereby increasing the rotation angle of the paper feeding roller during dismounting and being beneficial to dismounting operation.

The utility model makes it compared with prior art owing to adopt above technical scheme, and the setting of the axle sleeve by activity can increase the rotational angle of feeding-in roll when dismounting, more helps disassembling section.Improvement of the present utility model is very simple, and is very little to mechanism's entire effect, has good practical value.
Description of drawings
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent, below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated, wherein:
Fig. 1 illustrates a kind of paper advance mechanism schematic diagram of existing printer.
Fig. 2 illustrates the partial enlarged drawing of the paper advance mechanism of printer shown in Figure 1.
Fig. 3 illustrates the paper advance mechanism schematic diagram of the printer of the utility model one embodiment.
Fig. 4 illustrates the rotation schematic diagram of the paper advance mechanism of printer shown in Figure 3.
Fig. 5 illustrates the partial enlarged drawing of the paper advance mechanism of printer shown in Figure 3.
Fig. 6 illustrates the first axle sleeve schematic diagram of the utility model one embodiment.
The specific embodiment
Fig. 3 illustrates the paper advance mechanism schematic diagram of the printer of the utility model one embodiment.With reference to shown in Figure 3, the paper advance mechanism 200 of the printer of present embodiment comprises body 202 and feeding-in roll 204.For a class paper advance mechanism 200, body 202 can be a carton.Correspondingly, when paper advance mechanism 200 was other type, body 202 can also be other parts.Body 202 has the first relative axis hole 206a and the second axis hole 206b.In order unnecessarily to obscure goal of the invention of the present utility model, other details of body 202 is no longer launched to describe at this.
In the utility model, the paper advance mechanism of printer can be used for comprising the printer of laser printer, ink-jet printer.
Feeding-in roll 204 has the first end 204a and the second end 204b, and the first end 204a, one side is provided with claw 205.Wherein the first end 204a is located among the first axis hole 206a, and the second end 204b is located among the second axis hole 206b.Please, be arranged with the first movable axle sleeve 208a on the first end 204a in conjunction with the partial enlarged drawing of the paper advance mechanism of printer shown in Figure 5.When mounted, shilling first an end 204a passes the first axis hole 206a, and when first end was arranged in the first axis hole 206a, the first axle sleeve 208a can get involved between the first end 204a and the first axis hole 206a, and the constraint feeding-in roll first end 204a's is radially movable.
Make the second end 204b pass the second axis hole 206b then.Can be fixed with the second axle sleeve 208b on the second axis hole 206b, be used for retraining the radially movable of the feeding-in roll second end 204b.Also being provided with on the second end 204b can be around the part of the second end 204b external diameter or the locating slot 210 of whole circle, and this locating slot 210 is fixed the axial activity of restriction feeding-in roll 204 by a spacer 212 that is butted on the second axis hole 206b, one side with body 202.Thus feeding-in roll 204 is fixed on the body 202.
Fig. 6 illustrates the first axle sleeve schematic diagram of the utility model one embodiment.With reference to shown in Figure 6, first axle sleeve has the first footpath portion 282 that can be inserted in the first axis hole 206a, is exposed to the second outer footpath portion 284 of the first axis hole 206a, and from the protuberance 286 of the second footpath portion, 284 protrusions.This protuberance can make things convenient for the dismounting of axle sleeve on feed roll.In one embodiment, the first axle sleeve 208a for example is that rubber is made, so that bigger flexibility is arranged preferably by elastomeric material.
Because the first axle sleeve 208a is sheathed on the feeding-in roll first end 204a versatilely rather than is arranged on regularly among the first axis hole 206a, when needs dismounting feeding-in roll 204, with reference to shown in Figure 4, after spacer 212 is taken out from the locating slot 210 of the feeding-in roll second end 204b, utilize protuberance 286 that the first axle sleeve 208a is peeled off from the firstth axis hole 206a, towards extracting feeding-in roll 204, make the second end 204b is left the second axis hole 206b then away from the direction of the body second axis hole 206b.Feeding-in roll 204 will obtain bigger rotation space owing to the gap (its gap is by the thickness decision of the first footpath portion 282 of first axle sleeve) of the external diameter and the first axis hole 206a internal diameter of the feeding-in roll first end 204a this moment.The rotational angle of feeding-in roll shown in Fig. 4 204 can reach 18 °.In addition, because the existence of claw 205, the first axle sleeve 208a will be retained on the feeding-in roll and be difficult for losing.
Therefore, the paper advance mechanism of the printer of embodiment of the present utility model can increase the rotational angle of feeding-in roll when dismounting by the setting of movable axle sleeve, more helps disassembling section.Improvement of the present utility model is very simple, and is very little to mechanism's entire effect, has good practical value.
Though the utility model discloses as above with preferred embodiment; right its is not in order to limit the utility model; any those skilled in the art; in not breaking away from spirit and scope of the present utility model; when doing a little modification and perfect, therefore protection domain of the present utility model is worked as with being as the criterion that claims were defined.
