Description
Technical field
The present invention relates to photoelectronic imaging equipment technical field, refer in particular to a kind of cleaning roller without grounds travel grit.
Background technology
Cleaning roller is for fine particles such as the residual powdered carbon of the charged cylinder surface in the equipment such as memory dump machine or duplicator or paper powder.
As shown in Figure 1 the operation principle of duplicator or printer is described: be first with electric drum 1 by the surface of a certain amount of electro transfer to photoreceptor 3, then the laser produced by laser generator 9 is eliminated the electronics on position photoreceptor 3 not needing print, feed roller 6 adsorbs the carbon dust in cartridge 2, the carbon dust that feed roller 6 provides is adsorbed onto on the surface of photoreceptor 3 according to positive and negative attracting principle by the electronics still staying photoreceptor 3 surface, in like manner, one time carbon dust is turned the surface being drawn onto revolution belt 7 by transcription cylinder 5, when under the rotary action at head roll 4, the carbon dust on revolution belt 7 surface is adsorbed onto the surface of paper 8 again by secondary transcription cylinder 13, then the acting in conjunction of cylinder 10 and pressing roller 12 in heat under, melt and fixed toner in paper surface, the paper having formed portrait is finally discharged by paper ejection drum 11.Cleaning roller 14 fits in band electric drum 1, and cleaning roller 14 is not driver part, and it drives pivotal by band electric drum 1.Under pivotal state, cleaning roller 14 cleans the residual powdered carbon of band electric drum 1 surface attachment or paper powder.
The cleaning roller 14 of prior art is processed by tetragonal sponge material perforate, and then insert iron axle and be fixed, then carry out attrition process with grinder to sponge material, the shape after machining presents cylindrical shape.Due to cylinder be through attrition process formed, the grounds travel produced in process of lapping can enter in the small foam hole of sponge material, print time grounds travel can ooze out, affect printing effect, cause the decline of print quality.
Summary of the invention
The object of the invention is to provide a kind of cleaning roller without grounds travel grit for the deficiencies in the prior art, strip spongy layer is directly spirally wound on the skin of axle core, without the need to through attrition process, avoids the generation of grounds travel, play good cleaning effect, improve the quality of printing.
For achieving the above object, a kind of cleaning roller without grounds travel grit of the present invention, comprises axle core, and the skin of institute's axle core is provided with strip spongy layer, and described strip spongy layer is helically wound around the skin of described axle core.
As preferably, the side that described strip spongy layer contacts with axle core has been provided with the adhesive linkage of adhesion effect, and described strip spongy layer is adhered to the skin of described axle core by adhesive linkage.
As preferably, between described strip spongy layer and adhesive linkage, be provided with pliable and tough non-woven fabrics fiber layer.
As preferably, described adhesive linkage is Double-face gummed paper or glue.
As preferably, the width range of described strip spongy layer is 5 ~ 24 millimeters.
As preferably, the thickness range of described strip spongy layer is 1.9 ~ 3.6 millimeters.
As preferably, it is 30 ~ 60 degree that described strip spongy layer is helically wound around the lead angle a scope that axle core formed.
Beneficial effect of the present invention: a kind of cleaning roller without grounds travel grit, comprises axle core, the skin of institute's axle core is provided with strip spongy layer, and described strip spongy layer is helically wound around the skin of described axle core; Described strip spongy layer is directly spirally wound on the skin of axle core, without the need to through attrition process, avoids the generation of grounds travel, plays good cleaning effect, improve the quality of printing.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail.
Embodiment 1.
As shown in Figures 2 to 5, a kind of cleaning roller without grounds travel grit of the present invention, comprises axle core 141, and the skin of institute's axle core 141 is provided with strip spongy layer 142, and described strip spongy layer 142 is helically wound around the skin of described axle core 141.
The side that described strip spongy layer 142 contacts with axle core 141 has been provided with the adhesive linkage 143 of adhesion effect, and described strip spongy layer 142 is adhered to the skin of described axle core 141 by adhesive linkage 143.
Described adhesive linkage 143 is Double-face gummed paper or glue.Described strip spongy layer 142 is wound around the skin being bonded in axle core 141 in the shape of a spiral, and the later stage, without the need to through attrition process, avoids the generation of grounds travel, plays good cleaning effect, improves the quality of printing.Strip spongy layer 142 strong bond in the skin of axle core 141, effectively can be prevented the situation that strip spongy layer 142 peels off by adhesive linkage 143.
The lead angle a scope that described strip spongy layer 142 is helically wound around axle core 141 formation is 30 ~ 60 degree.The preferred lead angle a of the present embodiment is 45 degree.The object that lead angle a elects 45 degree as is the stability in order to ensure cleaning roller production quality, because lead angle a selects excessive or too smallly easily to form defective products.Strip spongy layer 142 is wound on axle core 141 not only firmly bonding by this helical, and is conducive to himself to the cleaning effect being with electric drum.
The width w scope of described strip spongy layer 142 is 5 ~ 24 millimeters, and thickness h scope is 1.9 ~ 3.6 millimeters.The width w of strip spongy layer 142 and thickness h can make cleaning roller fully be attached to the surface of band electric drum in this condition and range, thus reach good cleaning effect.
Cleaning roller without grounds travel grit of the present invention, strip spongy layer 142 is directly spirally wound on the skin of axle core 141, without the need to through attrition process, avoids the generation of grounds travel, plays good cleaning effect, improve the quality of printing.
Embodiment 2.
As shown in Figure 6, the difference of the present embodiment and embodiment 1 is to be provided with pliable and tough non-woven fabrics fiber layer 144 between described strip spongy layer 142 and adhesive linkage 143, non-woven fabrics fiber layer 144 light weight and pliable and tough, its object mainly adds the scalability of strip spongy layer 142.Be provided with the strip spongy layer 142 not easy fracture of non-woven fabrics fiber layer 144, more for ease of production, the processing in later stage.
The remainder of the present embodiment is identical with embodiment 1, repeats no more here.
Above content is only preferred embodiment of the present invention, and for those of ordinary skill in the art, according to thought of the present invention, all will change in specific embodiments and applications, this description should not be construed as limitation of the present invention.
