The specific embodiment
Fig. 3 to 5 shows three-dimensional exploded view, lateral plan and the three-dimensional combination figure according to the paper distributing mechanism of the utility model first embodiment respectively.Shown in Fig. 3 to 5, paper distributing mechanism group of the present utility model is located in the body 3, and comprises paper-feeding roller 2 and comber 1.Comber 1 comprises body 10, axial region 20 and two friction wheels 30.
It should be noted that, after doing suitably adjustment, for example add big friction wheel 32,32 ' width, omit the friction wheel 32 ' or the adapter 24 at the two ends of axial region 20, or increase the quantity of the friction wheel that is set in an adapter, the still purpose of attainable cost utility model and effect.Friction wheel 32 can be set on the side face or annular recess 26 of adapter 24, as shown in Figure 6.
It should be noted that in another example adapter 24 also can be omitted, this moment, friction wheel 32 was installed in the annular recess 21 of an end of axial region 20, as shown in Figure 7.Aforesaid friction wheel can be resilient ring, non-resilient ring or take turns wide (rimwidth) width is narrower and manufacturing cost is lower O type ring or general rubber wheel, it is fixed to the two ends of axial region 20 respectively, the external diameter of friction wheel is greater than the external diameter of trunk portion 12, and two friction wheels contact with paper-feeding roller 2.Therefore, friction wheels 30 can comprise O type ring or rubber wheel.
Paper-feeding roller 2 is driven and is rotated by propulsion source (such as motor), and contacts with friction wheels 30, and then produces external force in friction wheels 30 and axial region 20, and desires pivoting friction wheels 30 and axial region 20.
In order to reach the effect of separation, comber 1 and paper-feeding roller 2 are drawn close mutually, therefore must provide pressure that comber 1 is pressurizeed toward paper-feeding roller 2.In one example, can utilize the deadweight of comber 1 that comber 1 is pressed on the paper-feeding roller 2.Perhaps, this paper distributing mechanism can also comprise compression spring 50, and its contact comber 1 and the body 3 that paper distributing mechanism is installed are in order to impose aforementioned pressure so that comber 1 is pressurizeed toward paper-feeding roller 2.
Except above-mentioned pressuring method, also can use the torsion spring 60 that is connected to articulated section 16 and body 3 to come that arm 14 is imposed torsion provides aforementioned pressure so that comber 1 is pressurizeed toward paper-feeding roller 2, as shown in Figure 8.Perhaps, arm 14 itself is exactly an elastic body or comprises elastic parts, pressurizes toward the direction of paper-feeding roller 2 with the friction wheels 30 with comber 1 as long as so utilize the deadweight of the elasticity of arm 14 and comber 1 will impose aforementioned pressure.
Illustrate below with reference to Fig. 4 how paper distributing mechanism of the present utility model reaches the effect of separation.Paper-feeding roller 2 is rotated with friction wheels 30 rotations that drive comber 1, supposes that two pieces of paper are opened S1 and S2 enters between comber 1 and the paper-feeding roller 2 simultaneously.At this moment, paper-feeding roller 2 contacts with paper S1, and friction wheels 30 contact with paper S2.Paper-feeding roller 2 utilizes the lasting paper S1 that drives of the friction force between paper-feeding roller 2 and the paper S1 to advance.Can or can not rotate as for friction wheels 30, lean on paper S1 to decide by the strength that paper S2 drives friction wheels 30.The generation of aforementioned limitations torsion sees through the strength that paper S2 drives friction wheels 30 through being designed to overcome paper S1 especially, but can't overcome the strength that paper-feeding roller 2 drives friction wheels 30.Therefore, paper S2 fixed by the wheels 30 that rub or even by stored energy mechanism design (elasticity of the wheels 30 that for example rub itself) the paper S2 wheels 30 that rubbed are back driven, cause between paper S1 and the S2 and produce slide relative, avoid paper S2 to enter in the paper-feeding channel, reach the effect of separation.
Fig. 8 shows the lateral plan according to the paper distributing mechanism of the utility model second embodiment.As shown in Figure 8, the paper distributing mechanism of present embodiment also comprises retaining paper assembly 13, it for example is the retaining paper washer, and have the first end 13A and a second opposed end 13B, the first end 13A is fixed on the outside face 12A that is parallel to axial region 20 of trunk portion 12, the second end 13B then fixes and extends towards paper-feeding roller 2 directions, and can or can not contact with paper-feeding roller 2.It is earlier some paper S to be kept off before separation that retaining paper assembly mainly acts on, to increase the usefulness of paper distributing mechanism.Also promptly, retaining paper assembly is in order to stop that paper S enters between comber 1 and the paper-feeding roller 2 at least.
Fig. 9 shows the lateral plan according to the paper distributing mechanism of the utility model the 3rd embodiment.As shown in Figure 9, the comber 1 of present embodiment also comprises retaining paper assembly 13 ', has the first end 13A ' and second opposed end 13B ', and the first end 13A ' is fixed on the arm 14, and the second end 13B ' then fixes and extends towards paper-feeding roller 2 directions.Retaining paper assembly is in order to stop that paper S enters between comber 1 and the paper-feeding roller 2 at least when the multi-paper feed.
Figure 10 shows the lateral plan according to the paper distributing mechanism of the utility model the 4th embodiment.As shown in figure 10, the paper distributing mechanism of present embodiment also comprises retaining paper assembly 13 ", have the first end 13A " and second opposed end 13B ", the first end 13A " be fixed on the arm 14, the second end 13B " then fixing and extend towards paper-feeding roller 2 directions, and can or can not contact with paper-feeding roller 2.Same, retaining paper assembly is in order to stop that at least one paper S enters between comber 1 and the paper-feeding roller 2 when the multi-paper feed.
In paper distributing mechanism of the present utility model, because the external diameter of friction wheels 30 be big than the external diameter of trunk portion 12, trunk portion 12 can't contact paper-feeding roller 2, has only friction wheels 30 to contact paper-feeding roller 2.Therefore, only there are the friction wheels 30 can wearing and tearing and need be replaced, do not need complicated step, only need friction wheels 30 are withdrawed from by the two ends of axial region 20 and new friction wheels 30 are packed into getting final product and change friction wheels 30.Using under the situation of O type ring as friction wheel, more do not need to use any dismantling devices, only need utilize the elasticity of O type ring that it is withdrawed from and get final product.In addition, because axial region 20 can directly be fixed to trunk portion, therefore the external diameter of whole comber can be reduced effectively.
The specific embodiment that is proposed in the detailed description of preferred embodiment is only in order to convenient explanation technology contents of the present utility model, but not with the utility model narrow sense be limited to the foregoing description, in the situation that does not exceed spirit of the present utility model and claims, the many variations of being done is implemented, and all belongs to scope of the present utility model.
