Description
Technical field
The present invention relates to a kind of internal compression methods of sponge roller.
Background technology
In such as printer, duplicator or fax electronic imaging device system, it can use to supply sending for carbon dust
Powder roller, the clearer of cleaning member and the delivery roll of transmitting effect etc. are referred to as OA sponge rollers.Sponge is used in order to improve OA
Roller performance parameter is, it is necessary to be processed sponge roller.At present, to sponge roller working process, sponge roller is mainly improved
The performance parameters such as density, hardness, surface smoothness, anti-hair elasticity, permanent deformation, coefficient of friction rate, improve the original of sponge roller
Performance meets work requirements.
Traditional sponge roller treatment technology includes：Surface heat-treatent technology, surface spraying processing and whole full compression processing.
Surface heat-treatent technology：Sponge roller is assembled into rigid casing, by being heated rigid casing come the table to sponge roller
Face is heat-treated；Or after sponge roller is accommodated with blessing device, by single or multiple cylinders being surface-treated
Body using rotating or single rotating manner is heat-treated sponge roller surface simultaneously with pending roller material.At surface spraying
Reason：By spray equipment by the surface of coating even application to sponge roller, then by placing or putting into oven cooking cycle naturally
Mode Paint coagulation is made to be attached to the surface of sponge roller.Whole full compression processing：By the outer diameter sponge roller bigger than casing inner diameter
It is assembled into casing, is placed on oven for baking, the extruding of the high-temperature baking and casing of through a long time to sponge roller makes sponge roller
It is whole all to be compressed.
In Surface heat-treatent technology, the sponge roller after Surface heat-treatent, roller surface sponge can form one layer of thin melting
Layer, the melting layer and deformation layer on surface improve the performances such as the hardness, density and finish of sponge roller, but melting layer and deformation layer
The foam hole for resulting in the surface sponge of roller becomes smaller or even blocks, and the foaming of roller surface sponge need to be utilized to such as OA powder feeding rollers
The sponge roll shape that hole loads similar applications to the sponge roller surface blister pore performances such as carbon dust is unfavorable.The sea of surface spraying processing
Continuous roller, is equally faced with the above problem, and when sponge roller surface spraying, coating, coating can be entered in sponge foaming hole, caused
Foam hole is blocked, and for the purposes of improving the other parameter of sponge roller, sacrifices the patency of sponge roller surface cells.It is whole complete
The sponge roller of processing is compressed, the problem of roller surface sponge foaming hole is blocked equally is faced, in addition, to sponge entirety full compression
Afterwards, although the hardness and density of sponge roller all improve, the prolonged high temperature compressed muscle that can make sponge is pressed down so that sea
The flexibility decrease of continuous roller.
That is, traditional sponge roller treatment technology can cause sponge roller while the performance of sponge roller is improved
The foam hole of surface sponge becomes smaller blocking, is unfavorable for subsequent applications.
The content of the invention
Based on this, it is necessary to provide a kind of the interior of the sponge roller that foam hole that will not make sponge roller surface sponge becomes smaller blocking
