Abstract
The utility model relates to a doctor blade which is low in cost and good in sealability. The doctor blade is a sponge platy body formed through integral molding. Because good elasticity, a developed surface pore structure and good sealability of sponge are used, the manufactured doctor blade has the advantages of simple structure, low cost, good powder controllability, good elasticity, good sealability and the like.
Description
Technical field
The utility model relates to a kind of spare and accessory parts of laser printer, particularly relates to the powder outlet cutter of the low and good airproof performance of a kind of cost.
Background technology
Laser printer is one of current most widely used computing machine output peripheral equipment, it is to utilize optical, electrical, hot physics and the principles of chemistry, by interaction output character or image, whole imaging process can be divided into charging, exposure, development, transfer printing, photographic fixing, seven steps such as electricity clean, disappear.
In above-mentioned developing process, by developer roll rotate and powder outlet cutter push, the carbon dust between developer roll and powder outlet cutter is because friction is charged and thickness is evenly distributed on developer roll; It requires powder outlet cutter can provide certain elastic force in print procedure, and in life cycle, keeps stable; Because powder outlet cutter is positioned at the meal outlet of powder box, in use, need to by and the box body of developer roll and powder box between be sealed and matched, prevent from affecting printing effect and wasted toner because carbon dust leaks.
Conventional powder outlet cutter consists of metal knife rest and the metal blade that is welded on metal knife rest, and it provides elastic force by metal blade ground bending; In order to realize the sealing between powder outlet cutter and powder box, need to, in metal knife rest and powder box junction adhesive seal sponge, at metal blade and powder box end contact portion, also need adhesive seal sponge; So conventional powder outlet cutter has the high and shortcoming such as assembly technology is complicated of cost.
For the conventional high problem of powder outlet cutter cost, in the patent documentation that is CN202904228U at notification number, announced a kind of powder outlet cutter cheaply, the blade-like powder outlet cutter that it is made by TPE material, owing to there is no knife rest, by modes such as bonding, screws, be directly connected on the blade assembly wall of powder box, although this powder outlet cutter cost is low, but cannot solve the problem that needs sponge to seal; In addition, it is blade-like structure, cannot adapt to regeneration or the assembling of existing powder box, limits its range of application.
If sealed without sponge between powder outlet cutter and powder box, and can guarantee sealing, can simplify the linkage editor of powder outlet cutter.
Summary of the invention
Fundamental purpose of the present utility model be to provide a kind of simple in structure, cost is low and the powder outlet cutter of good airproof performance.
For realizing above-mentioned fundamental purpose, the powder outlet cutter that the utility model provides is the sponge plates that form by integrated mode, and forming shore hardness is the sponge plates of 40HA-70HA.
From above scheme, powder outlet cutter is the sponge plates that form by integrated mode, makes its cost not need to seal by extra sponge simultaneously, simplifies the linkage editor of powder outlet cutter; Because the surface of sponge-type powder outlet cutter has flourishing pore texture, compare with existing powder outlet cutter, can make carbon dust rub more fully, charged better; The powder outlet cutter of pore texture completes by friction cuttings carbon dust layer the control of carbon dust layer, compares with friction and Extrusion of the prior art, and control powder is more prone to and is more even; Due to the sealing of sponge itself, compare the better tightness between itself and developer roll with existing powder outlet cutter; Due to the flexibility of sponge, in use the infringement of developer roll is dropped to minimumly, improve the life-span of developer roll and guarantee long-term good printing effect; Can form by integrated mode the powder outlet cutter of different-thickness, according to carbon dust and the different requirement of developing, select the powder outlet cutter of different-thickness, realize best developing performance, be particularly suitable for using in powder box regeneration.
The xsect that concrete scheme is powder outlet cutter is " ┏ " shape.
From above scheme, because the xsect of powder outlet cutter is " ┏ " shape, adapt with the powder outlet cutter erecting frame of existing powder box, so be more suitable in the use of existing OEM powder box and universal powder box.
Another concrete scheme is, powder outlet cutter is being sealed and matched in corresponding part and is being formed with boss with powder box.
From above scheme, on being sealed and matched corresponding part at powder outlet cutter and powder box, be formed with boss, make the better tightness between powder outlet cutter and powder box; And boss height, hardness and elasticity can according to the powder outlet cutter mounting tool post on powder box and developing property require one-body moldedly, make that good airproof performance, the assembly technology of this powder outlet cutter is simple and usable range is wide.
Another concrete scheme is that the hardness of sponge plates is preferably 50HA.
One more specifically scheme be that powder outlet cutter is sealed and matched by the fixing mode of screw and powder box.
From above scheme, due to the elasticity of sponge, make screw fixing more firm.
Another mode and powder box that scheme is powder outlet cutter by buckle is more specifically sealed and matched.
From above scheme, due to the elasticity of sponge, buckle is obtained more firm.
Another more specifically scheme be that powder outlet cutter is sealed and matched by bonding mode and powder box.
From above scheme, due to the flourishing pore texture on powder outlet cutter, make bonding and sealing effectiveness is better.
Another is sealed and matched by mode and the powder box that scheme is powder outlet cutter by welding more specifically.
From above scheme, because the material of powder outlet cutter is sponge, more easily weld and good sealing effect.
