Abstract
The utility model relates to a locating device used in the production of a laser printer processing case, which comprises a base and a beam which is fixed on the base, wherein one end of the beam is provided with a convex pillar for inserting into a powder knife screwed hole, and a permanent magnet is arranged beside the other end of the beam. The locating device is convenient for fixing a powder knife to conduct the cleaning procedures.
Description
Technical field
The utility model relates to the locating device that uses in the laser printer processing box production, particularly is used for fixing the locating device of powder discharge blade of processing cartridge of laser printer.
Background technology
Electrophotographic image forming, for example laser printer is the photosensitive drums that has predetermined uniform potential by the laser scanning irradiation, forms electrostatic latent image on its surface.This electrostatic latent image is developed with predetermined carbon dust, and then will be transferred on the paper, the image fixing of transfer printing acquisition, become the visual image that naked eyes can be observed afterwards,---signal---conversion between the image that realizes image thus through the image that develops.
Common laser printer is provided with charging roller, photosensitive drums, laser scanning mechanism, developing apparatus, transfer roll and fixing roller etc. in its casing.Wherein, photosensitive drums charges to predetermined equally distributed electromotive force by charging roller, and response is formed corresponding to the electrostatic latent image for the treatment of print image by laser scanning mechanism emitted laser bundle.Store carbon dust in the container that developing apparatus is established within it, and utilize powder feeding roller and developer roll that carbon dust is sent to the photosensitive drums that has electrostatic latent image and reach the state of even covering electrostatic latent image.The visual image that forms on the photosensitive drums is transferred on the paper between photosensitive drums and the transfer roll by transfer roll, utilizes fixing roller that the carbon dust image on the paper is given photographic fixing at last.
Referring to Fig. 1,2, in the production run of existing laser printer processing box 1, the powder delivery cutter 102 that is used for regulating developer roll 101 surface carbon powder layer thickness must keep its adjusting range to have high spatter property before being assembled to handle box 1 inside.Manual cleaning way is normally adopted in the measure that guarantees this spatter property.Because powder delivery cutter 102 generally is made of the magnetic conductive metal support 103 and the soft flexure strip 104 of rigidity, and rigid support 103 has the square xsect, flexure strip 104 is fixed on the sidewall of rigid support 103 by the securing member of bolt and so on, therefore, when cleaning flexure strip 104, handwork is very easily polluted the adjusting range that flexure strip 104 is used to regulate developer roll 101 surface carbon powder layer thickness because be difficult to keep flexure strip 104 to obtain stable fixed in space attitude.
The utility model content
The utility model purpose be to provide be used for fixing in a kind of laser printer processing box production the powder delivery cutter locating device.This locating device can be easily fixedly the powder delivery cutter so that implement the operation of cleaning powder delivery cutter.
The locating device that uses in producing according to the laser printer processing box of above-mentioned purpose design comprises pedestal and is supported in crossbeam on the pedestal regularly.End at crossbeam is provided with the projection that is used for inserting powder delivery cutter screw.Near the other end of crossbeam, be provided with permanent magnet.
Preferably, the locating device that uses during aforementioned laser printer processes box is produced, its crossbeam along vertical to the upper end have along vertical to two different planes of height.The position of projection and permanent magnet all is on the lower plane.
More preferably, the locating device that uses during aforementioned laser printer processes box is produced, its permanent magnet is along crossbeam adjustable positions longitudinally.
The locating device that uses during laser printer processing box of the present utility model is produced, take after the mode of the permanent magnet of projection that is provided on the crossbeam locating and adjustable positions, the operator can powder delivery cutter one end by the screw sleeve on it on projection, obtain the location after the magnetic force adhesive that the other end of powder delivery cutter is then produced by permanent magnet.So, when cleaning powder delivery cutter, the spatial attitude of powder delivery cutter just can be maintained fixed, and is convenient to the adjusting range that the operator cleans the powder delivery cutter, and is unlikely to damage or pollutes the powder delivery cutter.

Embodiment
Referring to Fig. 3,4, show the utility model locating device A that in the laser printer processing box production run, uses.It comprises pedestal 201 and crossbeam 202.Crossbeam 202 is supported on the pedestal 201 regularly by securing members such as bolt or tenon fourth of the twelve Earthly Branches combination.Along vertical, the upper end outer wall of crossbeam 202 is provided with along its different two planes 203,204 of height, position of vertical.Lower plane 204, position is provided with projection 205 and permanent magnet 206.Projection 205 and permanent magnet 206 lay respectively at crossbeam 202 longitudinally near two ends.Projection 205 is cylindrical approximately, and it is protruded upward outside the plane 203 by plane 204.Permanent magnet 206 is embedded in crossbeam 202 inside of plane below 204, keeps one of its magnetic pole to flush with plane 204.Distance between two planes 203,204 is suitable with the sidewall thickness that the metal support 103 of powder delivery cutter 102 shown in Figure 2 is used for fixing flexure strip 104.
Referring to Fig. 5, when cleaning powder delivery cutter 102 shown in Figure 2, at first the sidewall that its magnetic conductive metal support 103 is used for fixing flexure strip 104 is placed on the plane 204, and screw 105 sleeve that are arranged in metal support 103 1 ends is fixed this end in the projection 205 of locating device A; The magnetic force that permanent magnet 206 produces is then fixed the other end adhesive of metal support 103, and the operator can clean the flexure strip 104 of powder delivery cutter 102 easily subsequently.
Referring to Fig. 6, show the utility model locating device embodiment two.The locating device A of the locating device of embodiment two and aforementioned embodiments one is structurally basic identical, and therefore identical component parts or feature adopt identical mark.Their difference is, the position that crossbeam 202 is used for holding permanent magnet 206 is arranged to along the cell body 207 of crossbeam 202 longitudinal extensions.Permanent magnet 206 can be in cell body 207 along the vertically moving of crossbeam 202, so that adapt to the length difference of different powder delivery cuttves 102.
