Detailed description of the invention
For further setting forth paper roll installing mechanism provided by the present invention, below in conjunction with preferred enforcement of the present inventionThe diagram of example is further described in detail.
Consult shown in Fig. 1, this paper roll installing mechanism comprises that one in order to support as the support of lower component and paper roll 6Pedestal 13, fixes a paper roll supporting shaft 14, one end shape of this paper roll supporting shaft 14 on this supporting base 13Become free end, and by the selective snap close of an active catch door 2, this active catch door 2 is by a gear door pivot 11Be articulated on this supporting base 13.
This active catch door 2 is for to reliably the stopping of paper roll 6, as shown in Figure 2, and described paper roll supporting shaft 14Free end there is a stopper slot 141,2 pairs, described active catch door should be provided with locking board by stopper slot 14121, this locking board 21 has auto-reset function. In order to make this locking board 21 can freely insert that this is spacingGroove 141, the free end of described this paper roll supporting shaft 14 has a guiding surface 142, this guiding surface 142Locking board 21 is entered in this stopper slot 141 by this free end guiding.
As shown in Figure 3, in order to ensure selective this paper roll supporting shaft 14 of snap close of locking board 21, i.e. this snap closePlate 21 has sliding stroke on active catch door 2, and described locking board is provided with 4 slide posts 211, described workMoving gear door 2 is provided with the sliding tray corresponding with this slide post 211 22, and this locking board 21 is under Action of Gravity FieldAutomatically reset. In addition for carrying out paper roll 6 while changing, the convenient unlocking operation to locking board 21, instituteState locking board 21 and be provided with unlocking operation handle 212.
In order to make active catch door 2 be convenient to open and locking, in paper roll installing mechanism provided by the present invention, liveBetween moving gear door 2 and supporting base 13, be provided with extension spring 12, the two ends of this extension spring 12 respectively with this active catch door2 is fixing with supporting base 13, and open or when locking, consolidate for two of this extension spring 12 when active catch door 2On fixed point and the no longer same straight line of gear door pivot 11.
Consult Fig. 3, for the Free-rolling that ensures that paper roll 6 can be on paper roll supporting shaft 14, described paper rollBack shaft 14 rolls to go here and there and overlaps a paper spool core 9, and the movable string of paper roll 6 is enclosed within on this paper spool core 9, described paperBetween scroll core 9 and paper roll supporting shaft 14, be provided with rolling member 8. This design makes the volume heart and the paper roll of paper roll 6Axle center 9 is line contacts, and frictional force is little between the two, the rotation of paper roll 6 while being convenient to print, paper roll axle center 9And between paper roll supporting shaft 14, there are 2 rolling members 8 that frictional force is minimum. Like this, this mechanism is dragging external diameterFor the paper roll of >=φ 152.4mm (φ 6 ") all has no pressure.
In addition, paper roll installing mechanism provided by the present invention, in order to ensure that paper roll supporting shaft 14 is in a support groupFirm fixing on seat 13, paper roll supporting shaft 14 is by the auxiliary supporting base 13 that is fixed on of a fixed head 15Upper, and carry out fastening by bolt 16 from the termination of paper roll supporting shaft 14. For what realize all partsFastening, as shown in Figure 3, need some securing members 1,4,7,10 and 16.
Below by shown in Fig. 4 to Fig. 9, further illustrate paper roll installing mechanism of the present invention and change paper rollProcess: as shown in Figure 4, in the time that paper roll 6 uses will be use up, need to change operation, now, first needWill on lift the lever 212 of locking board 21, make locking board 21 be lifted away from the stopper slot 141 of paper roll supporting shaft 14,As shown in Figure 7, being now pulled outwardly active catch door 2 can open, and active catch door 2 overcomes the bullet of spring 12Power is rotated and is opened around gear door pivot 11, when active catch door 2 rotates two fixing points and the gear that make extension spring 12Door pivot 11 is in same straight line and exceed after this straight line, and active catch door 2 keeps under the effect of spring 12Opening, as shown in Figure 5, the unlatching of active catch door 2 puts in place and has a position-limit mechanism certainly. By entire volumePaper roll be contained on paper spool core 9 after, carry out the process that closes of active catch door 2, when on active catch door 2Locking board 21 is during against the termination of paper roll supporting shaft 14, and locking board 21 is led paper roll supporting shaft 14 endsUnder the guiding on inclined-plane 142, upwards lift, as shown in Figure 7, active catch door 2 continues to close, until snap closePlate 21 is crossed the highest order of guiding surface 142, as shown in Figure 8, and because there is height stopper slot 141 both sidesPoor, lean on a side of guiding surface 142 lower than opposite side, locking board 21 is in deadweight and stopper slot 141 sidesUnder the effect of wall, latch in the stopper slot 141 of paper roll supporting shaft 14, as shown in Figure 9, so far whole paperThe Renewal process of volume is complete, and state now as shown in Figure 6, it should be noted that in addition, for locking boardThe Gravitative Loads power of locking board that 21 the present invention that automatically resets adopts, certainly can also be by spring or otherCan provide the mechanism of reset force to realize the auto-reset function of locking board 21. .
Below be only the preferred embodiment of the present invention, it should be pointed out that above-mentioned preferred embodiment shouldBe considered as limitation of the present invention, protection scope of the present invention should be as the criterion with claim limited range.For those skilled in the art, without departing from the spirit and scope of the present invention, also canTo make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
