Abstract
The utility model relates to a fitting roller for a printer. The fitting roller comprises a mandrel, a roller sleeve and a gear, wherein an axial cavity is arranged on the mandrel along the length direction of the mandrel, grinding lines are arranged on the outer surface of the roller sleeve clockwise or anticlockwise, the roller sleeve is arranged on one end of the mandrel, and the gear is arranged on the other end of the mandrel. A drive device drives the mandrel to rotate through the gear arranged on the mandrel, and the grinding lines arranged on the outer surface of the roller sleeve clockwise enables ink powder to be uniformly delivered to a subordinate fitting so that production efficiency is improved.
Description
Technical field
The utility model relates to a kind of accessory roller, relates in particular to a kind of printer accessory roller.
Background technology
Printer is one of output equipment of computer, is used for the Computer Processing result is printed on associated media.The kind of printer is a lot, as a minute cylindricality, sphere, wire-dot printer, ink jet type, heat-sensitive type, electromechanical, laser type etc.Printer adopts electrophotographic imaging forming apparatus to be charged to by scan light on the photosensitive medium of a predetermined potential and forms an electrostatic latent image.Developer for example carbon dust offers electrostatic latent image via developing apparatus, and demonstrates the image of developer, and this developer image is transferred on the printing paper through image bearing medium and transfer roll.When printing paper when being in contact with one another the fixing roller of rotation and the space between the backing roll, the developer image via heat and pressure fixing to this printing paper.
Printer needs ink powder is transmitted in the course of the work, and this just needs the accessory roller that ink powder is passed to subordinate's accessory from higher level's accessory, and traditional accessory roller is made up of mandrel and the roller shell that is coated on the mandrel, and the ink powder transmission effect is not good, influences print quality.
The utility model content
The purpose of this utility model is to overcome the defective that prior art exists, and a kind of printer accessory roller is provided.
The technical scheme that realizes the utility model purpose is: a kind of printer accessory roller, comprise mandrel, roller shell and gear, described mandrel is provided with axial cavity along the mandrel length direction, described roller shell outer surface is provided with the grinding line clockwise or counterclockwise, described roller shell is arranged at described mandrel one end, and described gear is arranged at the described mandrel other end.
Further, described mandrel is the polyformaldehyde mandrel.
Further, described roller shell is the polyurethane roller shell.
Further, the number of teeth of described gear is at least 10.
Further, described gear and mandrel are one-body molded.
The utlity model has positive effect: simple and reasonable, mandrel is provided with gear, and drive unit rotates by the gear driven mandrel, and the roller shell outer surface is provided with the grinding line clockwise and guarantees that ink powder passes to subordinate's accessory uniformly, enhances productivity.
Description of drawings
Content of the present utility model is easier to be expressly understood in order to make, according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail below, wherein:
Fig. 1 is structural representation of the present utility model.
Wherein: 1, roller shell, 2, mandrel, 3, gear.
The specific embodiment
Embodiment 1
As shown in Figure 1, the utlity model has a kind of printer accessory roller, comprise mandrel 2, roller shell 1 and gear 3, mandrel 2 is provided with axial cavity along mandrel 2 length directions, roller shell 1 outer surface is provided with the grinding line clockwise, and roller shell 1 is arranged at mandrel 2 one ends, and gear 3 is arranged at mandrel 2 other ends.
Wherein, mandrel 2 is polyformaldehyde mandrel 2, and roller shell 1 is polyurethane roller shell 1, and the number of teeth of gear 3 is 20.
In above-described embodiment 1, mandrel 2 is provided with gear 3, and drive unit drives mandrel by gear 3 and rotates, and roller shell 1 outer surface is provided with the grinding line clockwise and guarantees that ink powder passes to subordinate's accessory uniformly, enhances productivity.
All the other are identical with embodiment 1, and difference is that gear 3 is one-body molded with mandrel 2.
