Abstract
The utility model relates to a sectional-type conveying roller. The sectional-type conveying roller comprises a central spindle and at least two rubber sleeves, wherein a key groove is formed in any one end part of the central spindle, the width of the rubber sleeve 2 is 10-12mm, and the rubber sleeves are uniformly sheathed on the central spindle. The sectional-type conveying roller has the advantages that as an integral rubber sleeve in the prior art is replaced by the multiple rubber sleeves, the cost is saved, and the environment-friendly effect is achieved.
Description
Technical field
The utility model relates to a kind of carrying roller, relates in particular to the low sectional type carrying roller of a kind of cost.
Background technology
Printer is one of output device of computing machine, 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 printer paper through image bearing medium and transfer roll.When printer 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 printer paper.
In the prior art, developer image needs by carrying roller printer paper to be carried before to the printer paper, and general carrying roller is by mandrel and be coated on that rubber sleeve on the whole mandrel forms, and such infrastructure cost is than higher.
The utility model content
The purpose of this utility model is to overcome the defective that prior art exists, and provides a kind of cost low sectional type carrying roller.
The technical scheme that realizes the utility model purpose is: a kind of sectional type carrying roller, comprise mandrel and at least two rubber sleeves, and the arbitrary end of described mandrel is provided with keyway, and described rubber sleeve width is 10-12mm, and described rubber sleeve evenly is sheathed on the described mandrel.
Preferably, described mandrel outside surface is provided with nickel dam, and described nickel dam is 0.3-0.8 μ m.
Preferably, described rubber sleeve outside surface is provided with the grinding line clockwise or counterclockwise.
The utlity model has positive effect: a plurality of rubber sleeves replace existing whole rubber sleeve, have saved cost, have reached the effect of environmental protection.
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, mandrel, 2, rubber sleeve.
Embodiment
As shown in Figure 1, the utlity model has a kind of sectional type carrying roller, comprise mandrel 1 and four rubber sleeves 2, mandrel 1 one ends are provided with keyway, and rubber sleeve 2 evenly is sheathed on the mandrel 1, and rubber sleeve 2 width are 10mm, mandrel 1 outside surface is provided with nickel dam, and nickel dam is 0.3 μ m.
In above-described embodiment 1, utilize 4 rubber sleeves 2 to replace existing whole rubber sleeve, saved cost, reached the effect of environmental protection.
Embodiment 2
As preferred embodiment, all the other are identical with embodiment 1, and difference is that rubber sleeve 2 width are 12mm, and rubber sleeve 2 outside surfaces are provided with the grinding line clockwise.
In above-described embodiment 2, rubber sleeve 2 outside surfaces are provided with the grinding line, increase the friction force between carrying roller and the printer paper, thereby guarantee effective conveyance printer paper.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above only is specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
Claims (3)
