Abstract
The utility model provides a spiral cleaning cotton roller, which comprises a rotating shaft and strip-shaped cleaning cotton used for cleaning carbon powder on the surface of a charging roller, wherein the cleaning cotton is spirally wound on the side surface of the rotating shaft; the middle of the cleaning cotton is sunken downwards to form an arc-shaped groove with a lower middle and two higher sides; the utility model discloses an adopt spiral polyester sponge to bond on the iron axle, be spiral friction charging roller surface at the clean cotton roller of drum subassembly during operation, can be better will charge the carbon dust that the roller surface glues and additive clean, reduce the wearing and tearing of charging roller simultaneously, prolong the life of charging roller and drum core.
Description
Technical Field
The utility model relates to a printer consumptive material technical field, in particular to spiral clean cotton roller.
Background
The charging roller is widely used in the field of printers, copiers and fax machines, wherein the printers, copiers and fax machines are used for charging a photosensitive drum through the charging roller, exposing to form an electrostatic latent image, then conveying carbon powder to an electrostatic latent image part on the photosensitive drum through a developing roller, and conveying the carbon powder latent image to paper to be heated and shaped to form a final printed text image.
The current drum subassembly uses the clean roller that charges of an integral sponge roller, and clean effect is not good, and the roller that charges appears the surface easily and glues whitewashed phenomenon, and the result of use of duplicator can be influenced to serious condition. The main reason is that the cleaning roller has poor cleaning effect on the charging roller, resulting in failure to clean the powder from the surface of the charging roller.
Improvements are therefore needed.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a clean efficient, with low costs, clean effectual charge roller end automatic cleaning machine to solve above-mentioned problem.
The utility model provides a spiral clean cotton roller, includes the pivot and is used for the clean cotton of the bar of clean roller surface carbon dust that charges, clean cotton spiral is coiled the setting and is in the side surface of pivot.
In a further technical scheme, the middle of the cleaning cotton is sunken downwards to form an arc-shaped groove with a low middle and high two sides.
In a further technical scheme, two cleaning cottons are arranged in parallel.
In a further technical scheme, the cleaning cotton is made of polyurethane.
In a further technical scheme, the bottom of the cleaning cotton is provided with an adhesive which is fixedly attached to the side surface of the rotating shaft.
The utility model has the advantages that: the utility model discloses an adopt spiral polyester sponge to bond on the iron axle, be spiral friction charging roller surface at the clean cotton roller of drum subassembly during operation, can be better will charge the carbon dust that the roller surface glues and additive clean, reduce the wearing and tearing of charging roller simultaneously, prolong the life of charging roller and drum core.
Drawings
Fig. 1 is a schematic view of the overall structure of the present invention;
fig. 2 is a schematic cross-sectional structure of the cleaning cotton of the present invention.
Detailed Description
The invention is further explained below with reference to the drawings:
as shown in fig. 1 and 2, the spiral cleaning cotton roller comprises a rotating shaft 1 and strip-shaped cleaning cotton 2 for cleaning carbon powder on the surface of the charging roller, wherein the cleaning cotton 2 is made of polyurethane, the cleaning cotton 2 is spirally wound on the side surface of the rotating shaft 1, an adhesive is arranged at the bottom of the cleaning cotton 2 and fixedly attached to the side surface of the rotating shaft 1 through the adhesive, and two cleaning cotton 2 are arranged in parallel; the middle of the cleaning cotton 2 is sunken downwards to form an arc-shaped groove 3 with a lower middle and two higher sides.
During the use, install the cleaning roller in the printer, form the roller result with the roller that charges, at the in-process of printing, pivot 1 drives cleaning cotton 2 and rotates, because cleaning cotton 2 is that spiral winding sets up, consequently can rub the face of the roller that charges constantly at the pivoted in-process to the realization is in the roller surface that charges abundant cleanness, solves the sticky powder problem.
In addition, the surface of the cleaning cotton 2 can be provided with an arc-shaped groove 3 with a lower middle part and two higher sides, so that the contact pressure between the cleaning cotton 2 and the surface of the charging roller is increased, the carbon powder on the surface of the charging roller is scraped by utilizing the raised edges on the two sides and falls into the arc-shaped groove 3, the carbon powder is discharged in the rotating process along with the rotating shaft 1, and the cleaning capability of the cleaning cotton 2 roller is further improved; because the direct contact area of cleaning cotton 2 and the roller that charges is little, consequently can also reduce the wearing and tearing to the roller that charges, prolong the life of roller that charges.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
