Abstract
The invention discloses a clearing device for carbon powder on a photosensitive drum surface, which mainly comprises a bracket base, a photosensitive drum fixing unit, a motor and a dust collection unit, wherein the dust collection unit exists in a separation mode; the bracket base is provided with two brackets which are respectively provided with a centering round hole; the photosensitive drum fixing unit is composed of left and right thimbles and a spring, wherein one thimble is directly connected with a motor rotation shaft through one round hole of the brackets, and the other thimble passes through the other round hole of the brackets so as to be provided with a spring in a traversing mode. The invention can automatically and quickly adsorb dust, has simple structure and convenient use and can effectively clear residual carbon powder and dust on the photosensitive drum surface.
Description
Technical field
The present invention relates to a kind of clearing device for carbon powder on photosensitive drum surface, be specially adapted to print on the laser printer scavenge unit of back carbon powder on photosensitive drum surface.
Background technology
Along with the arrival of computer age, the application of laser printer also more and more widely, and maximum consumptive material is exactly a cartridge in printer module, and one of critical component in the cartridge is exactly photosensitive drums (OPC).OPC is by the organic photoconductor made, and the surface is very responsive, is subjected to pollutions such as external impacts and humidity easily.After last machine was printed, OPC surface meeting residual fraction carbon dust must be clean residual carbon dust clearing before making finished product.Remove the main two kinds of methods that adopt at carbon powder on photosensitive drum surface at present, wherein a kind of is to adopt pressurized air directly to blow, and shortcoming is that airshed is difficult to control, easily because of the too big impact failure photosensitive drums of airshed, simultaneously, the water droplet or the oil stain of trace can pollute photosensitive drums in the pressurized air.Another kind method is to adopt the suction cleaner of buying directly to inhale, and shortcoming is the distance that is difficult to control cleaner head and photosensitive drums, causes carbon powder on photosensitive drum surface not clean up.
Summary of the invention
The object of the present invention is to provide a kind of Special Automatic clearing device for carbon powder on photosensitive drum surface, the carbon dust of photosensitive drum surface is removed by its unique porous type cleaner head device.
A kind of clearing device for carbon powder on photosensitive drum surface of the present invention comprises bracket base, the photosensitive drums fixed cell, and motor, dust suction unit four parts, the photosensitive drums fixed cell is directly installed on the bracket base, and the dust suction unit separates and exists.Described bracket base mainly comprises pedestal, left and right sides support two parts, and two stands is directly installed on pedestal top, offers the circular hole of centering on the support of the left and right sides respectively.The photosensitive drums fixed cell comprises left and right sides thimble, spring two parts, and wherein the circular hole of a thimble by support directly links to each other with machine shaft, and another thimble is installed with a spring after passing another circular hole of support, and spring is used for compressing photosensitive drums between the support of the left and right sides.In concrete use, in the pin hole that is stuck in the photosensitive drums two ends and gear axis hole of two thimbles, this moment, spring was in compressive state, relied on the restoring force of spring, made photosensitive drums be held out against and fix by thimble.
Described dust suction unit comprises cleaner head, dust sucting pipeline, cleaner head brace table three parts, cleaner head is fixed on the cleaner head brace table, end face is arcs of recesses, porous type hollow in the arc, be used for slowing down powerful dust-absorbing airflow, can not cause damage to the photosensitive drums top layer, dust sucting pipeline and cleaner head tail end are solidly fixed.Cleaner head lateral length and photosensitive drums length adapt, can be more effective and realize the purpose of dust suction efficiently.
This contrive equipment is simple in structure, easy to use, and is harmless to the photosensitive drums top layer, can faster, more effectively remove impurity such as carbon dust on the photosensitive drums and dust, is a kind of desirable clearing device for carbon powder on photosensitive drum surface.
Description of drawings
With reference to the accompanying drawings the mentioned photosensitive drums carbon dust clearing device of the present invention is described further.
Fig. 1 is the structural representation of photosensitive drums carbon dust clearing device;
Fig. 2 is the synoptic diagram of cleaner head in the carbon dust clearing device.
Photosensitive drums as shown in the figure, 1, dust sucting pipeline, 2, motor, 3, bracket base, 4, right thimble, 5, cleaner head, 6, left thimble, 7, spring, 8, the cleaner head brace table, 9, air suction opening, 10.
Embodiment
The present invention finishes removing to carbon powder on photosensitive drum surface by following steps:
The first step is installed photosensitive drums, and photosensitive drums (10) is fixed on the bracket base (3).At first the gear end axis hole is through on the right thimble (4), promote left thimble (6) left, make spring (7) compression, the left end shaft pin-and-hole and left thimble (6) centering of photosensitive drums (10), trip spring (7) relies on the elastic force of spring (7) to hold out against photosensitive drums (10) automatically.
Second one, open the power supply of dust sucting pipeline, pull motor (2) switch simultaneously.Photosensitive drums (10) is at the uniform velocity rotation under the driving of motor (2), being fixed on the air suction opening (9) that distributes on cleaner head (5) end face on the cleaner head brace table (8) slows down from the strong negative-pressure air-flow in the dust sucting pipeline (1), make its even concentrated area act on photosensitive drums (10) top layer, the carbon dust and the dust on photosensitive drums (10) surface are siphoned away rapidly, finish reset procedure.
Claims (3)
1. clearing device for carbon powder on photosensitive drum surface, it is characterized in that this device comprises bracket base, the photosensitive drums fixed cell, motor, dust suction unit four parts, the dust suction unit separates and exists, two stands is arranged on the bracket base, and support is offered the circular hole of centering respectively, and the photosensitive drums fixed cell is made up of left and right sides thimble, spring two parts, wherein the circular hole of a thimble by support directly links to each other with machine shaft, and another thimble is installed with a spring after passing another circular hole of support.
2. according to claims 1 described clearing device for carbon powder on photosensitive drum surface, it is characterized in that, the dust suction unit comprises cleaner head, dust sucting pipeline, cleaner head brace table three parts, cleaner head is fixed on the cleaner head brace table, end face is arcs of recesses, arc inner structure porous type hollow, dust sucting pipeline and cleaner head tail end are solidly fixed.
3. according to claims 2 described dust suction unit, it is characterized in that: cleaner head lateral length and photosensitive drums length adapt.
