Description
Technical field
The utility model relates to a kind of handle box, more particularly, relates to a kind of handle box that sealing scraping blade is installed.
Background technology
Image imaging equipment is a kind of equipment that utilizes electrophotographic image forming principle to form image on recording materials, and image imaging equipment comprises duplicating machine, printer, facsimile recorder etc.The handle box using in image imaging equipment is generally divided into two kinds, a kind of is to comprise as the developer roll of developing apparatus and the one handle box of photosensitive drums, another kind is that photosensitive drums is separated to outer split handle box, and above-mentioned two kinds of handle boxes are all installed in the main body of image imaging equipment in mode removably.
A typical image imaging equipment laser printer, laser printer is one of image imaging equipment the most widely at present, laser printer utilizes optical, electrical, hot physics, the principles of chemistry output character or image on the media such as paper.
With reference to Fig. 1, Fig. 1 is existing a kind of structural drawing that is installed to the handle box on laser printer, handle box 1 comprises housing 11, housing 11 surrounds the cavity accommodating as the carbon dust of printing consumables, one end of cavity is provided with carbon dust outlet, in carbon dust exit, developer roll 12 is installed, below developer roll 12, seal assembly is installed, sealing assembly comprises sealing scraping blade 13 and seal 14.
With reference to Fig. 2, Fig. 2 is the sectional view of existing handle box, accommodates the carbon dust 17 as printing consumables in the cavity that housing 11 surrounds.When carrying out imaging, the puddle support 18 being arranged in cavity is carried carbon dust 17 toward powder feeding roller 16, powder feeding roller 16 transmits developer roll 12 by clockwise rotation by carbon dust 17, carbon dust 17 on developer roll 12 is undertaken after the adjusting of carbon dust thickness by powder outlet cutter 19, carbon dust 17 can be positioned at the photosensitive drums absorption outside split handle box, then carries out next step imaging.Visible, because carbon dust in cavity 17 need to carry out encapsulation process, otherwise can cause carbon dust 17 to be revealed.And the sealing means that existing handle box 1 adopts is for sealing by sealing scraping blade 13 and seal 14, seal 14 is made by sponge, seal 14 is fixed on the housing 11 of the below that is positioned at developer roll 12, and sealing scraping blade 13 is fixed on seal 14 and with developer roll 12 tangent planes and contacts.
Because sealing scraping blade 13 contact with developer roll 12 tangent planes, when sealing scraping blade 13 occurs in the situation of slight deformation, will cause sealing scraping blade 13 and developer roll 12 surface of contact and occur gap, thereby cause poorly sealedly, cause carbon dust 17 leakages, contaminated environment.Due in imaging process, developer roll 12 can be subject to printer body and rock and rock, and has caused sealing scraping blade 13 can not contact closely developer roll 12 simultaneously, can cause equally carbon dust 17 to be revealed.
Summary of the invention
Fundamental purpose of the present utility model is to provide a kind of handle box with good seal performance.
In order to realize fundamental purpose of the present utility model, the utility model provides a kind of handle box to comprise housing, developer roll and the first seal, housing surrounds the cavity that holds consumptive material, one end of cavity is provided with consumptive material outlet, developer roll is installed in cavity close in consumptive material exit, the first seal is arranged on the below of developer roll and fixedly in consumptive material outlet, wherein, handle box also comprises sealing scraping blade, sealing scraping blade comprises fixed part and contact site, fixed part is fixed in consumptive material outlet, the first end that contact site comprises with contact end face, first end and the first seal butt, contact end face and developer roll elasticity butt.
From such scheme, contact end face by fixed part and first end as the strong point, keep elasticity butt with developer roll, make developer roll when shaking, contact end face, owing to having elastic restoring force, still keeps butt with developer roll, utilizes contact end face to contact with developer roll simultaneously, make to seal scraping blade and be not easy distortion, be conducive to improve sealing property and the durability of handle box.
Further scheme is, fixed part is bonded in consumptive material outlet.
Therefore, by fixed part be fixed as contact end face elastic restoring force a good fulcrum is provided, make to contact end face better elasticity be connected to developer roll.
Further scheme is, the joint gap place of fixed part and consumptive material outlet scribbles fluid sealant.
Therefore because the volume of carbon dust is minimum, fixed part there will be gap when being arranged on housing, carbon dust can be revealed from gap, so scribble fluid sealant at the joint gap place of fixed part and consumptive material outlet, is conducive to prevent carbon dust leakage.
Further scheme is, fixed part and the contact site of sealing scraping blade are one-body molded.
Therefore integrated sealing scraping blade has good elastic restoring force.
Further scheme is, sealing scraping blade is made by pet material.
Therefore pet material (being called for short PET material) has good mechanical property, has fatigue durability when having rub resistance, owing to improving the serviceable life of handle box.
Further scheme is, the angle between contact site and fixed part under non-stress state in obtuse angle or right angle.
Further scheme is, contact jaw face comprises the stress surface with developer roll elasticity butt, and the angle of stress surface and fixed part is acute angle.
Further scheme is, obtuse angle is 120 °, and acute angle is 60 °.
Therefore, under non-stress state, the angle of contact site and fixed part is 120 ° or 90 °, sealing scraping blade by developer roll and elasticity butt after, with stress surface and the fixed part angle of developer roll elasticity butt be 60 °, because sealing scraping blade has elastic restoring force, thus can keep the elasticity butt with developer roll, thus improve the sealing property of handle box.
Further scheme is, the two ends of contact site are also separately installed with the second seal and the 3rd seal, the second seal and the 3rd seal all with the first abut.
Therefore, by increase seal at two ends, make the two ends that seal scraping blade under the effect of two seals, be more close to developer roll, be conducive to improve the sealed at both ends of handle box consumptive material outlet.
Further scheme is, described the first seal, described the second seal and the 3rd seal are made by sponge or felt.
Therefore good slump resistance energy and the favorable elasticity restoring force of utilizing sponge or felt to have, be conducive to improve the sealing property of handle box.
