Fig. 2 is the birds-eye view of Fig. 1.
Fig. 3 is the left view of Fig. 1.
Among the figure: the 1-helical gear; 2-paper bowl gear; The 3-assembly holder that commutates; 4-inflatable mandrel; The 5-support; The 6-bevel gear shaft; 7-the second gear; The 8-right clutch; The 9-axle sleeve; The 10-left clutch; 11-the first gear; The 12-finishing bevel gear cuter.
The specific embodiment
Below in conjunction with accompanying drawing this is advanced to be further described:
Such as Fig. 1, Fig. 2, shown in Figure 3, disengaging type rewinding mechanism of the present utility model comprises: frame, inflatable mandrel component, helical gear assembly and three parts of commutation assembly form.
Wherein, the inflatable mandrel component comprises inflatable mandrel 4, is connected to the paper bowl gear 2 of inflatable mandrel right part, and the axle sleeve 9 that is sleeved on inflatable mandrel right-hand member, is connected by bearing between this axle sleeve 9 and the inflatable mandrel 4.This assembly is mainly used in transmission inflatable mandrel 4 and carries out rewinding, mounting core cylinder on the inflatable mandrel 4, and by corresponding backing roll cooperation, finish the rewinding of paper.
The helical gear assembly comprises helical gear 1 and support 5, and this helical gear 1 is provided with negative thread and external tooth, when this assembly is mainly used in the rewinding end, drives the telescopic translation of inflatable mandrel, so that debatching, the core cylinder that more renews.
The commutation assembly comprises finishing bevel gear cuter 12, bevel gear shaft 6, left and right electric clutch, the first gear 11 and the second gear 7; Be used for the commutation engagement of finishing bevel gear cuter 12, drive respectively corresponding assembly and carry out rewinding or debatching.
Wherein, helical gear 1 is sleeved on outside the axle sleeve 9 and passes through screw thread fit between the two, and this axle sleeve 9 also is sleeved on the frame by support 5; Drive inflatable mandrel 4 by axle sleeve 9 mobile together, be convenient to debatching.Support 5 main rising are supported and directional tagging.
When the first gear 11 is meshed with helical gear 1, be used for transmission debatching power.When the second gear 7 is meshed with paper bowl gear 2, be used for transmission rewinding power.The rotating shaft both sides of finishing bevel gear cuter 12 connect respectively left and right electric clutch, and left electric clutch 10 is connected with the first gear 11; Right electric clutch 8 is connected with the second gear 7.Cooperate with different electric clutch by control finishing bevel gear cuter 12, can change the transmission direction of finishing bevel gear cuter 12, when cooperating with left electric clutch 10, the driving debatching; When cooperating with right electric clutch 8 devices, drive rewinding.The rotating shaft of finishing bevel gear cuter 12 is also supported by commutator support 3, and first, second gear is installed on the frame by bearing seat respectively.
