Detailed description of the invention
For further setting forth paper roll installing mechanism provided by the present invention, be further described in detail below in conjunction with the diagram of the preferred embodiments of the present invention.
Consult shown in Fig. 1, this paper roll installing mechanism comprises that one in order to support as the supporting base 13 of lower component and paper roll 6, on this supporting base 13, fix a paper roll supporting shaft 14, one end of this paper roll supporting shaft 14 forms free end, and by the selective snap close of an active catch door 2, this active catch door 2 is articulated on this supporting base 13 by a gear door pivot 11.
This active catch door 2 is for to reliably the stopping of paper roll 6, as shown in Figure 2, the free end of described paper roll supporting shaft 14 has a stopper slot 141, and 2 pairs, described active catch door should be provided with locking board 21 by stopper slot 141, and this locking board 21 has auto-reset function.In order to make this locking board 21 can freely insert this stopper slot 141, the free end of described this paper roll supporting shaft 14 has a guiding surface 142, and this guiding surface 142 enters locking board 21 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, this locking board 21 has sliding stroke on active catch door 2, described locking board is provided with 4 slide posts 211, described active catch door 2 is provided with the sliding tray corresponding with this slide post 211 22, and this locking board 21 automatically resets under Action of Gravity Field.In addition for carrying out paper roll 6 while changing, the convenient unlocking operation to locking board 21, described locking board 21 is provided with unlocking operation handle 212.
Be convenient to open and locking in order to make active catch door 2, in paper roll installing mechanism provided by the present invention, between active catch door 2 and supporting base 13, be provided with extension spring 12, the two ends of this extension spring 12 are fixing with supporting base 13 with this active catch door 2 respectively, and open or when locking when active catch door 2, on two fixing points of this extension spring 12 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 roll supporting 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, between described paper spool core 9 and paper roll supporting shaft 14, is provided with rolling member 8.It is that line contacts with paper roll axle center 9 that this design makes the volume heart of paper roll 6, and frictional force is little between the two, and the rotation of paper roll 6 while being convenient to print has 2 rolling members 8 that frictional force is minimum between paper roll axle center 9 and paper roll supporting shaft 14.Like this, this mechanism all has no pressure for the paper roll of >=φ 152.4mm (φ 6 ") dragging external diameter.
In addition, paper roll installing mechanism provided by the present invention, in order to ensure firm fix of paper roll supporting shaft 14 on supporting base 13, paper roll supporting shaft 14 is assisted and is fixed on supporting base 13 by a fixed head 15, and carries out fastening by bolt 16 from the termination of paper roll supporting shaft 14.In order to realize fastening to all parts, 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 the process of paper roll: as shown in Figure 4, in the time that paper roll 6 uses will be use up, need to change operation, now, first need to 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, now being pulled outwardly active catch door 2 can open, the elastic force that active catch door 2 overcomes spring 12 rotates and opens around gear door pivot 11, make two fixing points of extension spring 12 and keep off door pivot 11 in same straight line and exceed after this straight line when active catch door 2 rotates, active catch door 2 is held open state under the effect of spring 12, as shown in Figure 5, certainly the unlatching of active catch door 2 puts in place and has a position-limit mechanism.After the paper roll of entire volume is contained on paper spool core 9, carry out the process that closes of active catch door 2, when the locking board 21 on active catch door 2 is during against the termination of paper roll supporting shaft 14, locking board 21 upwards lifts under the guiding of the guiding surface 142 of paper roll supporting shaft 14 ends, as shown in Figure 7, active catch door 2 continues to close, until locking board 21 is crossed the highest order of guiding surface 142, as shown in Figure 8, because there is difference in height stopper slot 141 both sides, lean on a side of guiding surface 142 lower than opposite side, locking board 21 latches in the stopper slot 141 of paper roll supporting shaft 14 under the effect of deadweight and stopper slot 141 sidewalls, as shown in Figure 9, so far the Renewal process of whole paper roll is complete, state now as shown in Figure 6, it should be noted that in addition, the Gravitative Loads power of the locking board adopting for the present invention that automatically resets of locking board 21, certainly can also can provide the mechanism of reset force to realize the auto-reset function of locking board 21 by spring or other.。
Below be only the preferred embodiment of the present invention, it should be pointed out that above-mentioned preferred embodiment should not be 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, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
