Power Receiver 40 has the driving shaft 402 of the wedge of running through 41, briquetting 42, the first elastic bodys 43 and the power Receiver dip plane 401 with 1 combination of image processing system driving head.Power Receiver dip plane 401 is with respect to photosensitive drums axial direction inclination certain angle β.
Referring to accompanying drawing 1～to Figure 14, below by the principle of work that specifically describes handle box and pack image processing system into and take out from image processing system.
In the time that handle box is loaded to image processing system along the guide rail 60 of image processing system, power Receiver dip plane 401 just contacts (as shown in a in 9) with the inclined-plane 101 of image processing system driving head 1, user packs handle box in image processing system into, power Receiver 40 is subject to after power F effect, the inclined-plane 101 of image processing system driving head 1 and dip plane 401 sliding contacts (as shown in b in Fig. 9) of power Receiver 40, power Receiver 40 is subject to the effect of the component F1 of power F at axial direction, power Receiver 40 is contracted to predetermined stroke at axial direction, reach (as shown in c in Fig. 9) state.When the handle box with said structure packs image processing system into along image processing system guide rail 60, between moving Receiver 40 and image processing system driving head 1, can not produce interference.In the time that handle box is in place in image processing system, image processing system driving head 1 falls into the receiving position 412 of power Receiver 40, and compressed the first elastic body 43, because be no longer subject to the effect of power F1 at axial direction, will recoil to original position.When after the electric motor starting in image processing system, power Receiver 40 engages with image processing system driving head 1, and power Receiver 40 receives the driving force of image processing system, thereby transfers a driving force in handle box.
Handle box of the present invention, inclined-plane sliding contact is passed through with image processing system driving head 1 in power Receiver dip plane 401, and the mode of shrinking to produce extruding at axial direction simultaneously, solved the problem of power Receiver 40 with the 1 installation interference of image processing system driving head, thereby the driving force in image processing system can be delivered in handle box swimmingly.
Find by a large amount of experimental data demonstrations, in the time that the inclination angle beta of power Receiver dip plane 401 is less than 20 °, the wall thickness h of power Receiver dip plane 401 is too little, the intensity of power Receiver dip plane 401 is too little, is not enough to support the power transferring power of itself and image processing system driving head 1.As shown in Figure 9, in installation process, power Receiver 40 is subject to the effect of component F1 at axial direction, wherein, F1=F.cos β, in the time that β is greater than 75 °, F1 is too little, can not make power Receiver 40 be contracted to predetermined stroke at axial direction, and cause power Receiver 40 and image processing system driving head 1 to interfere, handle box can not pack in image processing system.In the present embodiment, in conjunction with the factor of installation and power Receiver 40 intensity, inclination angle beta optimal selection is 55 °, now, the wall thickness h of power Receiver dip plane 401 is moderate, intensity enough supports the effect of itself and image processing system driving head 1, and the power F1 being subject at axial direction is enough large, power Receiver 40 can easily be compressed in predetermined stroke, handle box can pack in image processing system swimmingly, and work normally in image processing system, power Receiver dip plane 401 is set to 20 °～75 ° with respect to the inclination angle beta of photosensitive drums axial direction.
When completing after print out task, user takes out handle box from image processing system, the handle 21 of handing up on handle box, apply a power F2 straight up to handle box, handle box moves upward, now, the guide rail 60 of image processing system is oppressed the control part 31 of driving stem 30, applies a downward power F3 to driving stem 30.Driving stem 30 is subject to after the effect of power F3, will be around fulcrum 22 M rotation in the counterclockwise direction.The urgent pushed section 33 of driving stem 30 is moved to the inclined-plane along wedge 41 411 top of wedge 41 by the bottom of wedge 41, in this process, driving stem 30 applies an axial downward power to wedge 41, wedge 41 is owing to being limited to two parallel plane a1 and the a2 of bulging support 50, so can only shrink at axial direction, thereby and can there is not double swerve, 40 of power Receivers are shunk at axial direction, power Receiver 40 departs from and interferes with image processing system driving head 1, thereby user can pull out handle box backward swimmingly along the guide rail of image processing system 60.
In the present invention, handle 21 is arranged on and is more close to drive end 24 with respect to conducting end 25, user upwards puies forward the directed force F 2 of handle box like this, to act on more drive end 24 than conducting end 23, the control part 31 that is arranged in the driving stem 30 of drive end 24 1 sides more easily coordinates with the guide rail 60 of image processing system, is more conducive to driving stem 30 along being rotated counterclockwise.In the present embodiment, handle 21 inserts the direction of image processing system with respect to handle box, is arranged on the below of box body 20.In the time that user takes out handle box from image processing system, hand is placed on the handle 21 of box body lower end, naturally applies a power F2 upwards as shown in figure 12 to handle box.The present invention contacts with the inclined-plane 411 in wedge 41 by the urgent pushed section 33 of driving stem 30, revolving force on driving stem 30 is converted to the power that power Receiver 40 is shunk in the axial direction, cause power Receiver 40 axially to shrink downwards, depart from completely with image processing system driving head 1, thereby complete the taking-up of handle box.
On drive assembly of photosensitive drum of the present invention, be designed with wedge 41 to innovation, wedge 41 is provided with the inclined-plane 411 that an angle of inclination is Ф.The inclined-plane 411 of wedge 41 is mutually corresponding with the shape of the urgent pushed section 33 of driving stem 30, so the angle of inclination Ф on the inclined-plane 411 of wedge 41 should be controlled in certain angle, just can make the urgent pushed section 33 and inclined-plane 411 no-floats of driving stem 30.Angle of inclination Ф is too large or too little, and the urgent pushed section 33 of driving stem 30 all can not successfully move upward along the inclined-plane of wedge 41 411 and power Receiver 40 is pressed into drum gear 44.Learn through a large amount of experiments, when the angle of inclination Ф on the inclined-plane 411 of wedge 41 is less than 20 while spending, the axial shrinkage stroke of power Receiver 40 is too small, can not make power Receiver 40 complete the disengaging from image processing system driving head 1, thereby cause handle box and image processing system to be interfered, can not from image processing system, take out.In the time that the angle of inclination Ф on the inclined-plane 411 of wedge 41 is greater than 70 °, wedge 41 is in the time being converted to wedge 41 axial direction motoricity by the revolving force of driving stem 30, it is excessive that driving stem 30 is limited by the power of inclined-plane 411 axial directions of wedge 41, the rotation of driving stem 30 is obstructed, can not complete the conversion of force direction, cause the power Receiver 40 can not be in axial direction normal contraction.In the present embodiment, for wedge 41 is normally coordinated with driving stem 30, ensure that power Receiver 40 shrinks swimmingly at axial direction, angle of inclination Ф is preferably 35 °.In the present invention, the angle of inclination Ф on the inclined-plane 411 of wedge 41 can be set to 20 °～70 °.There is the wedge 41 of said structure, can realize the revolving force of driving stem 30 is converted into and makes power receive 40 axial forces of shrinking, thereby realize power Receiver 40 in axial direction free shrink.
When handle box takes out from image processing system, the control part 31 of driving stem 30 is oppressed by the guide rail 60 of image processing system, and driving stem 30 will rotate around fulcrum 22.Control part 31 one end of driving stem 30 are subject to the oppressive force F3 that image processing system applies, and the size of the power that 33 one end, urgent pushed section are subject to is determined to the Length Ratio of the distance of fulcrum 22 to distance and the urgent pushed section 33 of fulcrum 22 by the control part 31 in driving stem 30.In the present embodiment, the center superposition of fulcrum on box body 22 and pilot hole 32, control part 31 and urgent pushed section 33 equal control part 31 and 33 points of urgent pushed sections and are clipped to respectively the distance of pilot hole 32 to pivot distance.Control part 31 is set to L1 to the distance of fulcrum 22, and compeling pushed section 33 to the distance of fulcrum 22 is L2.Show through a large amount of experimental data demonstrations, in the time that L1:L2 is 1:5, compeling pushed section 33 just can make power Receiver 40 axial shrinkage to predetermined stroke, now power Receiver 40 disengages with image processing system driving head 1, in the time that L1:L2 is less than 1:5, driving stem 30 is subject to inclined-plane 411 reacting forces of wedge 41 while rotation excessive, and rotatablely moving of driving stem 30 is obstructed.In the time that L1:L2 is 5:1, the power that urgent pushed section 33 is subject to just makes power drive 40 axial shrinkage to specific stroke, and in the time that L1:L2 is greater than 5:1, it is too small that power Receiver 40 is activated bar 30 revolving forces, can not make power Receiver 40 be retracted to predetermined stroke, cause interference.In the present embodiment, for driving stem 30 can being rotated freely and can making power Receiver 40 shrink at axial direction, L1:L2 is preferably designed to 3:4.So the control part 31 in handle box of the present invention in driving stem 30 is 1:5～5:1 with urgent pushed section 33 to the Length Ratio of the distance L 2 of fulcrum 22 to the distance L 1 of fulcrum 22.
Handle box of the present invention arrives the Length Ratio L1:L2 of the distance of fulcrum 22 to the distance of fulcrum 32 and urgent pushed section 33 by controlling control part 31 in driving stem 30, thereby make driving stem 30 control the contraction of power Receiver 40 at axial direction, reach the power Receiver 40 of handle box and can freely engage and depart from engagement with the image processing system driving head 1 in image processing system, smooth and easy and stably by the power transmission in image processing system to handle box.
