Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
Be fixed in frame 8 see Fig. 1 support arm 4, coil paper 1 is arranged on support arm 4, coil paper 1 passes from the gap of last item 5 and wheel hub 2, when external force draws coil paper end, coil paper can at the move under influence of frictional force, and last item 5 is by presses paper thus provide enough frictional force can better cut off with toilet tissue.
See Fig. 1, handwheel 3 is arranged in frame 8, in one end of wheel hub 2, initial new coil paper is installed time, manual 3 take turns by rotating this and make coil paper 1 mobile to a direction (paper delivery direction).
See Fig. 9-Figure 12, main shaft part 701 and the support of eccentric shaft are fixed, and the centre bore of wheel hub 2 is arranged in the main shaft part 701 of eccentric shaft, and receive from entire volume paper lira paper out, wheel hub 2 is columned.In time having external force to pull coil paper, wheel hub 2 can rotate at main shaft part 701 place along paper delivery direction round eccentric shaft.Wheel hub 2 is made up of two semicylindrical portions, is installed together by draw-in groove.Wheel hub 2 outer surface has an elongated slot, hand papercutter can be stretched out and return back to inside wheel hub.Wheel hub outer surface is the material that one deck is softer, to strengthen frictional force and the absorption affinity of coil paper and wheel hub, makes coil paper drive wheel hub to rotate under the effect of frictional force, thus completes a cut paper cycle.On wheel hub, have several grooves, the muscle that (or on base) has several to protrude on bonnet matched, such mechanism can effectively make coil paper be close to wheel hub, thus makes hand papercutter effectively can cut off coil paper simultaneously.
Hand papercutter 601 is arranged on (fixed axis) in the main shaft part 701 of eccentric shaft, and hand papercutter 601 is triangle profiles of tooth, and the cut paper tool arm at two ends is arranged in the side guide groove of wheel hub.When coil paper drives wheel hub to rotate, hand papercutter is by the gathering sill of wheel hub also and then motion, and hand papercutter rotates round eccentric part 702 place of eccentric shaft.And wheel hub 2 rotates round main shaft part 701.When hand papercutter 601 is below the outer surface of wheel hub 2, there is no cut paper action; When hand papercutter stretches out the outer surface of wheel hub, start to carry out cut paper, after cutting paper, hand papercutter return back to again below the outer surface of wheel hub, forms a cut paper circulation.Detailed process is as shown in Fig. 3-Fig. 7.
What Fig. 3 showed is that after cut paper system cuts paper, hand papercutter return back to below wheel hub outer surface, and the direction of arrow is the direction of rotation of wheel hub.This time, wheel hub was in relaxation state, and paper extraction machine is in original state.If now have external force to draw coil paper, so shown in cut paper system motion to Fig. 4.
What Fig. 4 showed is when there being external force to draw coil paper, and wheel hub starts to rotate in the direction of arrows, simultaneously hand papercutter also setting in motion, and now hand papercutter is also in below wheel hub outer surface, not yet starts cut paper.
What Fig. 5 showed is that hand papercutter is now about to stretch out wheel hub outer surface, starts cut paper action.
What Fig. 6 showed is that hand papercutter stretches out wheel hub outer surface, completely just at cut paper.
What Fig. 7 showed is that cut paper action closes to an end, and hand papercutter is slowly returning back to below wheel hub outer surface.
What Fig. 8 showed is that cut paper action terminates, and hand papercutter is continuing to return back to below wheel hub outer surface.Wheel hub 2 can continue to rotate forward under the effect of back-moving spring, and now paper is broken by the pulling force of people, drive while wheel hub upwards resets the coil paper at rear march forward to so that implement to extract action next time.
Figure 13-Figure 14 mainly indicates the installation site of back-moving spring 9, composition graphs 3-Fig. 8, when hand papercutter 601 wheel hub 2 ultimate range rear drum 2 continues rotating in same direction and resets under back-moving spring 9 drives, described paper disconnects position and disconnects completely, wheel hub 2 drive rear coil paper 1 march forward to.
Figure 15 mainly indicate wheel hub and on gathering sill 201, the position of elongated slot 202 and structure.
The utility model provides a kind of mechanical mechanism, can reach performance and the function of similar paper extraction machine, and simplify and install, cut paper is reliable and stable, reduces cost of parts.Paper extraction machine uses field extensive, any there is substantive cost efficiency change, improve and all can bring huge Social benefit and economic benefit, there is higher creativeness.
