Abstract
The utility model discloses a rubber roller exhaust structure of a printer, which comprises an iron shaft and a rubber sleeve; the rubber sleeve is sleeved on the outer ring of the iron shaft; an exhaust groove is arranged between the rubber sleeve and the iron shaft in contact. The rubber roller exhaust structure of the printer changes the situation that in the prior art, a small amount of air can be left between the rubber sleeve and the iron shaft and between the rubber sleeve and the rubber, and the small amount of air can gradually expand or contract along with the change of temperature, so that the shape of the rubber roller is changed, and the phenomenon of poor printing effect is caused; the residual air in the rubber roller can be smoothly discharged completely (or communicated with the outside), so that the environmental temperature change is achieved, the appearance of the rubber roller is not influenced, and the printing quality is ensured.
Description
Technical field
The utility model relates to printer exhaust applied technical field, is specially a kind of printer rubber roller exhaust structure.
Background technology
A lot of parts in the office equipment such as printer, duplicator can use rubber rollers, as: charging roller, developer roll etc. The method of current rubber rollers moulding has: compressing, assembly, extrusion molding etc. But current method, all will be on iron axle coating adhesive, and production efficiency is low.
For reducing coating adhesive operation, in extrusion molding process, rubber is extruded into after tubulose, continuous vulcanization, then iron axle is pierced into rubber tube, make rubber rollers, iron axle does not just need coating adhesive like this, and production efficiency can improve 40% left and right. But between rubber roll and iron axle, have air residual like this, residual air can be along with the variation of temperature, produces and expands or shrink, and causes rubber rollers profile to change, and then affects print quality.
Utility model content
The purpose of this utility model is to provide a kind of printer rubber roller exhaust structure, and it can effectively solve the problem existing in background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of printer rubber roller exhaust structure, comprises iron axle and rubber sleeve; Described rubber sleeve is set in iron axle outer ring; Described rubber sleeve and iron are provided with air discharge duct between being coupling and touching.
Further, described air discharge duct is coupling between touching and is evenly provided with three at rubber sleeve and iron.
Compared with prior art, the beneficial effects of the utility model are: this printer rubber roller exhaust structure, change in prior art, rubber sleeve and iron axle and rubber between can residual a small amount of air, the a small amount of air of this part can be along with the variation of temperature, progressively expand or shrink, thereby causing the shape of rubber rollers to change, then occurring the situation of printing effect bad phenomenon; Can be successfully by clean the residual air discharge in rubber rollers (or with extraneous UNICOM), thereby reach variation of ambient temperature, can not have influence on rubber rollers profile, ensure print quality. Overall structure is simple, cheap, practical, is easy to promote the use of.
Brief description of the drawings
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 be in this Fig. 1 A-A to cutaway view;
In Reference numeral: 1-iron axle; 2-rubber sleeve; A-air discharge duct.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment. Based on the embodiment in the utility model, those of ordinary skill in the art are not making all other embodiment that obtain under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1-2, the utility model provides a kind of technical scheme:
A kind of printer rubber roller exhaust structure, comprises iron axle 1 and rubber sleeve 2; Described rubber sleeve 2 is set in iron axle 1 outer ring; Between contacting, described rubber sleeve 2 and iron axle 1 be provided with air discharge duct a.
Further, described air discharge duct a is evenly provided with three between rubber sleeve 2 and iron axle 1 contact.
Although illustrated and described embodiment of the present utility model, for the ordinary skill in the art, be appreciated that in the situation that not departing from principle of the present utility model and spirit and can carry out multiple variation, amendment, replacement and modification to these embodiment, scope of the present utility model is limited by claims and equivalent thereof.
