The specific embodiment
Explain embodiment of the present utility model below in conjunction with accompanying drawing:
As shown in Figures 1 to 10, the printer that the utility model discloses comprises the body 1 accommodating for carbon ribbon group 8 and coordinates upper cover group 2 with body 1 activity, and carbon ribbon transmission connecting mechanism of the present utility model comprise be located at the carbon ribbon transmission case 3 of body 1 one sides, with convexedly stretch in carbon ribbon rotating shaft 4 resilient engagement outside carbon ribbon transmission case 3 carbon ribbon swivel head 5, be located at the pushing block 6 of upper cover group 2 one end belows, and with the movable carbon ribbon connector 7 coordinating of carbon ribbon swivel head 5.
In described carbon ribbon transmission case 3, be provided with power-jdriven gear, to rotate in response to signal enabling carbon ribbon rotating shaft 4, this carbon ribbon rotating shaft 4 protrudes out in body 1 from carbon ribbon transmission case 3, form the body of rod of noncircular cross section at carbon ribbon rotating shaft 4, object is the rotational freedom of restriction carbon ribbon rotating shaft 4, drive carbon ribbon rotating shaft 4 to rotate, this embodiment is formed with two planes that are parallel to each other 41, form a draw-in groove 42 in the end of carbon ribbon rotating shaft 4, the spacing carbon ribbon swivel head 5 being matched with on carbon ribbon rotating shaft 4 to coordinate jump ring 43, between jump ring 5 and carbon ribbon swivel head 4, be also provided with a back-moving spring 9 simultaneously.
Coordinate shown in Fig. 4,5, described carbon ribbon swivel head 5 is a cylinder, and its rear end outer rim near carbon ribbon transmission case 3 forms taper seat 51, and inner edge forms and leans end face 52, the front portion of carbon ribbon swivel head 5 is to form cavity volume, and be distributed with convex tendon 54 on this cavity volume periphery, carbon ribbon swivel head 5 front ends of this example are to form the internal conical surface 53 concentric with its external cylindrical surface, on this internal conical surface 53, be and be circumferentially evenly distributed with six convex tendons 54, further to form two inclined-planes 55 that intersect and form pinnacle on the top of each convex tendon 5, side forms by the vertical surface with angle angle 56 in axle center, to form two vertical surfaces 56 that angle 29 is spent herein, groove 57 angles between adjacent two convex tendons 54 are 31 degree, the another non-circular mating holes 58 passing for carbon ribbon rotating shaft 4 that forms on carbon ribbon swivel head 5.
Coordinate shown in Fig. 2,3, the carbon ribbon swivel head 5 of column type is enclosed within on carbon ribbon rotating shaft 4, can slide axially along carbon ribbon rotating shaft 4.In the middle of opening plastic cement jump ring 43 and carbon ribbon swivel head 5, it is back-moving spring 9.When carbon ribbon swivel head 5 is under external force F effect, can move to from right to left vertically operating position, swivel head back-moving spring 8 is compressed, after external force F cancels, under back-moving spring 9 elastic force effects, carbon ribbon swivel head 5 is returned to the original position shown in Fig. 2 from left to right.
Coordinate shown in Fig. 6, described upper cover group 2 is to be articulated on body 1 by drive-connecting shaft 21, if 6 lower ends of pushing block thereon form fluting 61, after upper cover group 2 and body 1 fasten, this fluting 61 is just buckled on carbon ribbon rotating shaft 4, on this pushing block 6, be provided with one perpendicular to 62, one groups of oblique surfaces 63 that form an angle with plane 62 of drive-connecting shaft 21 plane, fluting 61 is herein the opening arc grooves take drive-connecting shaft 21 as the center of circle.In the time that upper cover group 2 is rotated around drive-connecting shaft 21, pushing block 6 rotates with upper cover group 2 simultaneously.In the situation that upper cover group 2 is opened, carbon ribbon group 8 can be assembled to body 1 from the opening of lower cover group 2 tops, and is positioned by carbon ribbon bracing frame 81.
As shown in Figure 7, described carbon ribbon group 8 comprises carbon ribbon bracing frame 81, two carbon ribbon mandrels 82 and encloses by carbon ribbon mandrel 82 carbon ribbon twining, and the two ends of carbon ribbon mandrel 82 are provided with carbon ribbon connector 7.
As shown in Figure 8, the raised line 71 of corresponding above-mentioned carbon ribbon swivel head 5 further groove 57 quantity of annular spread on described carbon ribbon connector 7, this implementation column is that six raised lines 71 are set.This carbon ribbon connector 7 is by an outer cone cambered surface 72, two have the vertical surface 73 of angle by axle center, intersect at two, top and the inclined-plane 74 and the inner arc surface 75 that form pinnacle forms, between two adjacent raised lines 71, form dented space 76, and the angle between adjacent recessed space 76 is 31 degree, between adjacent straight facade 73, angle angle is 29 degree.
In the time of the concrete implementation of printer of the present utility model, in the situation of uncapping, carbon ribbon swivel head 5 is returned to the original position on right side under the effect of back-moving spring 9, and the end face 52 of carbon ribbon rotating shaft 5 is to lean on carbon ribbon transmission case 3.Now carbon ribbon group 8 can be assembled to body 1 and by carbon ribbon bracing frame 81 and position from the opening of body 1 top.Put well after carbon ribbon group 8, upper cover group 2 is during around drive-connecting shaft 21 rotating close cover, oblique surface 63 on pushing block 6 first touches inclined-plane 55(on carbon ribbon swivel head 5 as shown in Figure 9), in the process pressing down in upper cover group 2, to promote carbon ribbon swivel head 5 mobile and engage with carbon ribbon connector 7 gradually vertically for oblique surface 63.The circular arc fluting 61 carbon ribbon rotating shafts 4 that can avoid on carbon ribbon transmission case 3 on pushing block 6.Under outer cone cambered surface 72 on internal conical surface 53 and carbon ribbon connector 7 on carbon ribbon swivel head 5 cooperatively interacts, carbon ribbon swivel head 5 and carbon ribbon connector 7 be the concentric position of guidance axis gradually.Simultaneously because convex tendon 54 tops on carbon ribbon swivel head 5 have two to intersect the inclined-plane 55 on pinnacle and there are two inclined-planes, inclined-plane 74 that intersect pinnacle on raised line 71 tops on carbon ribbon connector 7.Under the guide effect on these two pinnacles, the convex tendon 54 on carbon ribbon swivel head 5 enters the dented space 76 on carbon ribbon connector 7, and raised line 71 on carbon ribbon connector 7 enters the groove 57 on carbon ribbon swivel head 5.
As shown in figure 10, in the time that upper cover group 2 closures put in place, carbon ribbon swivel head 5 and carbon ribbon connector 7 engage completely.Carbon ribbon swivel head 5 arrives operating position.Now the plane 62 on pushing block 6 is fitted completely with the end face 52 on carbon ribbon swivel head 5, has stoped carbon ribbon swivel head 5 to be returned to original position under the effect of back-moving spring 9 elastic force.In the time that carbon ribbon transmission case 3 is started working, carbon ribbon swivel head 5 starts rotation under the drive of carbon ribbon rotating shaft 4, and by the vertical surface 73 on the carbon ribbon connector 7 of vertical surface 56 promotions and its laminating, thereby the carbon ribbon mandrel 82 in carbon ribbon group 8 is rotated.
Need to change carbon ribbon group 8 time, upper cover group 2 is opened, after plane 62 on pushing block 6 departs from completely with the end face 52 on carbon ribbon swivel head 5, carbon ribbon swivel head 5 is returned to original position under the effect of back-moving spring 9 elastic force, carbon ribbon swivel head 5 and carbon ribbon connector 7 depart from engagement completely, now can take out easily carbon ribbon group 8 and change.
As can be seen here, the utility model is synchronizeed rotation by one with carbon ribbon rotating shaft 4, the carbon ribbon swivel head 5 that can slide on carbon ribbon rotating shaft 4 simultaneously, whether it engages with the carbon ribbon connector 7 in carbon ribbon group 8 installation or removal that realize carbon ribbon, and the slip of this carbon ribbon swivel head 5 is to rely on the pushing block 6 of upper cover group 2 to realize.Therefore, the utlity model has simple in structure, compact, simultaneously convenient and swift installation and effect of changing carbon ribbon.
