Abstract
The utility model relates to a kind of carrying roller, comprises roller core and at least one is set in running roller on roller core; Described each running roller comprises plastic body and is set in the rubber ring on plastic body; Described plastic body is set on roller core, and is connected with roller core by spline.Compared to prior art, the utility model is by being arranged to a plastic body and the rubber ring being wrapped in plastic body periphery by running roller, can pass through in plastic body transmission, decrease the thickness of rubber ring, thus decrease the torsional forces of the tangential direction of rubber, prevent from producing skidding between rubber ring and plastic body.Further, this plastic body is connected with roller core by spline, makes the connection between roller core and plastic body more firm, prevents the skidding of plastic body and roller core.
Description
Technical field
The utility model relates to a kind of carrying roller, particularly a kind of carrying roller preventing running roller and roller core from skidding.
Background technology
Carrying roller is absolutely necessary parts on the equipment such as printer, mainly plays the effect of transmission paper.Existing carrying roller generally comprises roller core and is arranged on the multiple running rollers on roller core.Wherein, described running roller is generally rubber rolling.
Be strapped on roller core by the elasticity of rubber during connection due to rubber rolling and roller core.And the radius of running roller is larger, the required torsional forces of the tangential direction of running roller is larger.And due to the softness of rubber rolling and resilient characteristic, when ADF, the tangential direction of this rubber rolling can cause torsional deformation, have impact on the effect of ADF, also can cause skidding between rubber rolling and roller core simultaneously.
Utility model content
The utility model is that the shortcoming overcoming prior art is with not enough, provides a kind of carrying roller preventing running roller and roller core from skidding.
The utility model is realized by following technical scheme: a kind of carrying roller, comprises roller core and at least one is set in running roller on roller core; Described each running roller comprises plastic body and is set in the rubber ring on plastic body; Described plastic body is set on roller core, and is connected with roller core by spline.
Compared to prior art, the utility model is by being arranged to a plastic body and the rubber ring being wrapped in plastic body periphery by running roller, can pass through in plastic body transmission, decrease the thickness of rubber ring, thus decrease the torsional forces of the tangential direction of rubber, prevent from producing skidding between rubber ring and plastic body.Further, this plastic body is connected with roller core by spline, makes the connection between roller core and plastic body more firm, prevents the skidding of plastic body and roller core.
As further improvement of the utility model, described plastic body comprises a cylindrical exterior ring cap and is arranged on the cylindrical inner ring sleeve in this exterior ring cap; This interior cover that changes is fixedly connected with exterior ring cap by least one brace.By plastic body is set to inner ring sleeve and exterior ring cap, plastic material can be saved.
As further improvement of the utility model, described brace is 4, is evenly arranged on inner ring sleeve respectively and changes outward between cover.
As further improvement of the utility model, between described adjacent two braces, be respectively equipped with a filler piece.By filler piece, increase the intensity between plastic body.
As further improvement of the utility model, described rubber ring outer surface is provided with solarization line.By arranging solarization line, the frictional force on frame rubber ring surface can be increased.
As further improvement of the utility model, one end of described roller core is provided with the connecting portion of a notch cuttype.By notch cuttype connecting portion, the connection of the driving shaft of the equipment such as convenience and printer, realizes the rotation of roller core.
In order to understand better and implement, describe the utility model in detail below in conjunction with accompanying drawing.
Accompanying drawing explanation
Fig. 1 is the structural representation of carrying roller of the present utility model.
Fig. 2 is the structural representation of running roller of the present utility model.
Detailed description of the invention
Refer to Fig. 1, it is the structural representation of carrying roller of the present utility model.Carrying roller of the present utility model, comprises roller core 1 and at least one is set in running roller 2 on roller core 1.In the present embodiment, described running roller 2 is 2.
One end of described roller core 1 is provided with the connecting portion 11 of a notch cuttype, and described connecting portion, in order to connect the driving shaft of printer, realizes the rotation of roller core 1.
Refer to Fig. 2, it is the structural representation of running roller 2 of the present utility model.The rubber ring 21 that described each running roller 2 comprises plastic body 22 and is set on plastic body 22; Described plastic body 22 is set on roller core 1, and is connected with roller core 1 by spline.
Further in order to save the material of plastic body 22, the cylindrical inner ring sleeve 222 that described plastic body 22 comprises a cylindrical exterior ring cap 221 and is arranged in this exterior ring cap 221.This interior cover that changes is fixedly connected with exterior ring cap 221 by least one brace 223.Concrete, described brace 223 is 4, is evenly arranged on inner ring sleeve 222 respectively and changes outward between cover.
In order to reinforce the connection between inner ring sleeve 222 and exterior ring cap 221 further, between described adjacent two braces 223, be respectively equipped with a filler piece 224.
In order to strengthen the frictional force of rubber ring 21 periphery further, described rubber ring 21 outer surface is provided with solarization line.
The utility model is by being arranged to a plastic body 22 and the rubber ring 21 being wrapped in plastic body 22 periphery by running roller 2, can pass through in plastic body 22 transmission, decrease the thickness of rubber ring 21, thus decrease the torsional forces of the tangential direction of rubber, prevent from producing skidding between rubber ring 21 and plastic body 22.Further, this plastic body 22 is connected with roller core 1 by spline, makes the connection between roller core 1 and plastic body 22 more firm, prevents the skidding of plastic body 22 and roller core 1.
As further improvement of the utility model, the cylindrical inner ring sleeve 222 that described plastic body 22 comprises a cylindrical exterior ring cap 221 and is arranged in this exterior ring cap 221; This interior cover that changes is fixedly connected with exterior ring cap 221 by least one brace 223.By plastic body 22 is set to inner ring sleeve 222 and exterior ring cap 221, plastic material can be saved.
The utility model is not limited to above-mentioned embodiment, if do not depart from spirit and scope of the present utility model to various change of the present utility model or distortion, if these are changed and distortion belongs within claim of the present utility model and equivalent technologies scope, then the utility model is also intended to comprise these changes and distortion.
