Embodiment
Below in conjunction with embodiment and accompanying drawing, the present invention is described in further detail, but embodiments of the present invention are not limited only to this.
Embodiment 1:
As shown in Figure 1, based on the fixing component improved paper duplicating or quality of scanning, comprise the housing 15 of inner hollow, induction heating pipe 10 is provided with in described housing 15, the outer wall of induction heating pipe 10 is sheathed with warm-up mill 11, the center line of warm-up mill 11 overlaps with the center line of induction heating pipe 10, induction heating pipe 10 is connected with thermistor 12, warm-up mill 11 outer setting has pressure roller 9 and thermostat 13, gap is there is between pressure roller 9 and warm-up mill 11, thermostat 13 is near warm-up mill 11, reclaiming plate 1 is provided with above housing 15, reclaiming plate 25 and two outlet rollers 1, the bottom of reclaiming plate 1 and reclaiming plate 25 is all arranged on housing 15 inside through housing 15, and reclaiming plate 1 and reclaiming plate 25 are fixed on housing 15, the top of reclaiming plate 1 and the top of reclaiming plate 25 are towards between two outlet rollers 1, the bottom of reclaiming plate 1 is arranged on above warm-up mill 11, the bottom of reclaiming plate 25 is arranged on above pressure roller 9, reclaiming plate 1 is provided with hot-rolling disengaging pawl 14 and hot-rolling disengaging pawl 14 towards the gap between pressure roller 9 and warm-up mill 11, reclaiming plate 25 is provided with pressure roller disengaging pawl 3 and pressure roller disengaging pawl 3 towards the gap between pressure roller 9 and warm-up mill 11, it is inner that hot-rolling disengaging pawl 14 and pressure roller disengaging pawl 3 are all arranged on housing 15, clearer 8 is provided with in housing 15, pressure roller 9 is arranged between clearer 8 and warm-up mill 11, cam 6 is provided with above clearer 8, cam 6 contacts with clearer 8, poke rod 17 is provided with in cam 6, poke rod 17 contacts with pressure roller disengaging pawl 3 through after cam 6.Warm-up mill 11 and pressure roller 9 thereof are all need to rotate that just paper to be made normally to obtain fixing.So drive the motor at fixing position to drive, after machine, there is a mair motor, and having a series of gear (for drawing in figure), by power transmission, drive fixing position.Machine, before duplicating or printer, first needs a preheating time, and this preheating time, the warm-up mill 11 mainly in fixing position needed the temperature arriving machine expection setting, and after only reaching this temperature, machine could start normally duplicating.General when paper is gone between fixing heating roller 11 and pressure roller 9, these two rollers just form a kind of mutual pressure, add the high temperature of warm-up mill 11, the carbon dust on paper can be dissolved on paper, and be fixed up.When paper passes through between warm-up mill 11 and pressure roller 9, clearer 8 rotates thereupon, cam 6 is rotated, thus pressure roller disengaging pawl 3 is stirred by poke rod 17, pressure roller 9 and paper are separated by pressure roller disengaging pawl 3, avoid the clamping of pressure roller 9 and paper, hot-rolling disengaging pawl 14 separates paper and warm-up mill 11, avoiding paper to be pasted onto on warm-up mill 11 causes paper embrittlement even burned, fixing quality is guaranteed, the gap of paper between hot-rolling disengaging pawl 14 and pressure roller disengaging pawl 3 is passed through, eventually through two complete whole fixing operations of outlet roller 1, thermostat 13 makes warm-up mill 11 to remain on stationary temperature, the temperature making paper fixing can remain on the temperature of setting, according to the temperature in housing 15, thermistor 12 determines that induction heating pipe 10 needs the temperature of heating, to ensure that warm-up mill 11 realizes suitable temperature, fixing better effects if, this fixing component passes through modified node method, increase tripping device, can make paper heat after just be separated, paper be there will not be stuck, improve the fixing quality of image, solve the friction due to paper when fixing of existing fixing component, easy generation paper jam phenomenon, paper is made to occur damaging, make the phenomenon causing device interior stuck, the problem that can't meet the quality requirement that paper duplicates or scans.
Described housing 15 outer setting has cooling fan 7, and cooling fan 7 to be fixed on housing 15 outer wall and to be communicated with housing 15 inside.Because the heating of induction heating pipe 10 makes temperature raise in housing 15, being convenient to keep internal heat distribute, the power that cooling fan 7 circulates as inner air being set, air circulation is accelerated.
Described reclaiming plate 25 is fixed with outlet inductor 4, the contact of outlet inductor 4 is arranged between reclaiming plate 1 and reclaiming plate 25.Outlet inductor 4 is monitored outlet paper, to prove the normal of equipment work, paper enters into after between reclaiming plate 1 and reclaiming plate 25 just by the contact or extruding with outlet inductor 4, make to export the appearance that inductor 4 experiences paper, prove that this operation of assembly is working properly.
Be provided with cover plate 16 above described housing 15, cover plate 16 is arranged on the top of reclaiming plate 1 and reclaiming plate 25, and cover plate 16 can cover the top of reclaiming plate 1 and the top of reclaiming plate 25 completely.Because housing 15 is stretched out on the top of reclaiming plate 1 and reclaiming plate 25, then easily entered by dust etc., cause paper easily stuck therein, even made dirty by dust etc., adopt cover plate 16 to shelter from dust, protect the clean of paper.
The above; it is only preferred embodiment of the present invention; not any pro forma restriction is done to the present invention, every according to technology of the present invention, method in fact to any simple modification, equivalent variations that above embodiment is done, all fall within protection scope of the present invention.
