As shown in figure 3, the present invention provides a kind of live roller, including transmission shaft 1 and the idler wheel that is placed on transmission shaft 1
2, it is connected by a bearing 3 between transmission shaft 1 and idler wheel 2, a clutch driving unit 4 is fixed on transmission shaft 1；Transmission shaft 1 rotates
When, clutch driving unit 4 on idler wheel 2, and drives its rotation from the side action of idler wheel 2；When transmission shaft 1 slows down or stops,
Clutch driving unit 4 is detached with 2 side of idler wheel, and idler wheel 2 is rotated freely along transmission shaft 1.The present invention on transmission shaft 1 by being nested with
One clutch driving unit 4 generates friction force when starting transmission base plate movement between clutch driving unit 4 and idler wheel 2,
To realize the rotation of driving idler wheel；It needing to stop when being transmitted substrate, transmission shaft 1 is in halted state at this time, and from
Conjunction driving device 4 generates between idler wheel side at this time to be detached, and friction force does not occur therebetween, idler wheel is in the used of substrate
Property effect is lower to stop suddenly, but stopping of gradually slowing down after moving a distance together with substrate, which reduces bases
Cut on plate, contributes to protective substrate.
Embodiment 1
As shown in Figure 3 and Figure 4, clutch driving unit 4 therein includes propeller shaft sleeve 41 and arc interference piece 42, drive shaft
Set 41 is fixed on transmission shaft 1, and interference piece 42 is set to the side of the close idler wheel 2 of propeller shaft sleeve 41, idler wheel 2 and interference piece
Arc groove 5 is formed on 42 opposite sides, interference piece 42 is set in arc groove 5.Preferably by arc in the present invention
Central angle corresponding to groove 5 is less than 360 °, and more than the central angle corresponding to interference piece 42；Since interference piece 42 is located at arc
In groove 5, when starting, transmission shaft 1 drives interference piece 42 to rotate, and the end of interference piece 42 resists the end of arc groove 5
Portion drives idler wheel 2 to rotate, and when stopping the rotation of transmission shaft 1, the zerofriction force in arc groove 5 of interference piece 42 rotates, at this time
Idler wheel continues after following substrate to rotate one end distance forward, when the other end of interference piece 42 contradicts the other end to arc groove 5
Behind portion, idler wheel is stopped rotating.

As shown in figure 5, clutch driving unit 4 includes propeller shaft sleeve 41 and arc interference piece 42, propeller shaft sleeve 41 is fixed on
On transmission shaft 1, interference piece 42 is set to one end of the close idler wheel 2 of propeller shaft sleeve 41, the side opposite with interference piece 42 of idler wheel 2
On form driving convex shoulder 6, interference piece pass through driving drive convex shoulder drive idler wheel rotation.
As different from Example 1, driving convex shoulder 6 is provided in the present embodiment on the side of idler wheel 2, by interference piece
The active force at both ends and driving convex shoulder may be implemented to start idler wheel and stop control.
Embodiment 3
As shown in fig. 6, clutch driving unit 4 therein includes propeller shaft sleeve 41 and arc interference piece 42, propeller shaft sleeve 41
Be fixed on transmission shaft 1, interference piece 42 is set to one end of the close idler wheel 2 of propeller shaft sleeve 41, idler wheel 2 with 42 phase of interference piece
To annular side on the one annular annular groove 7 that gradually deepens of molding, protruded from the shallower one end molding one of annular groove 7
The driving convex shoulder 6 of 2 lateral surface of idler wheel, be formed by between outside drive surface and annular groove 7 that idler wheel 2 passes through interference piece 42 by
Gradually increased frictional force drives idler wheel 2 rotates, when starting the rotation of idler wheel 2, by institute's shape between annular groove 7 and interference piece 42
At gradual increased frictional force, gradually drive idler wheel rotation, when needing substrate stop motion, by annular groove with interference
It is formed by the frictional force gradually decreased between piece, interference piece is made to progressively disengage the side of idler wheel, gradually uses up substrate and rolling
Frictional force between wheel makes idler wheel taper off rotation.Interference piece to idler wheel by applying the work for ramping up and gradually slowing down
Firmly, can greatly reduce to the cut caused by substrate surface.
Embodiment 4
As different from Example 3, the interference piece in the present embodiment uses as shown in fig. 7, the lateral surface of interference piece is one
Lozenges 8, and an annular groove is molded in the annular side of idler wheel 2, lozenges is set in parallel with annular groove, and idler wheel is logical
It crosses between lozenges and annular groove and is formed by gradually increased frictional force drives idler wheel rotation.When starting idler wheel rotation,
The lozenges of interference piece gradually gradually decreases at a distance from annular groove, when the two fits together, generated frictional force
Gradually increase, and then gradually idler wheel is driven to generate rotary motion；Conversely, when needing to stop substrate conveying, the ring of idler wheel side
Connected in star and the lozenges of interference piece distance gradually increase, and idler wheel issues to be born from the effect of inertia of substrate to be turned, until interference piece
End and idler wheel side generate friction until, so that idler wheel is stopped completely, drive substrate conveying and stopping in terms of, this
Embodiment will all play a protective role to substrate surface.
Embodiment 5
As different from Example 4, it is protruded from outside idler wheel 2 in the shallower one end molding one of annular groove 7 in the present embodiment
The driving convex shoulder 6 of side can further prevent interference piece to be detached from roller surface.
It is of course also possible to clutch driving unit 4 is set on the transmission shaft 1 of 2 both sides of idler wheel.
Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or
It changes.There is no necessity and possibility to exhaust all the enbodiments.And it is extended from this it is obvious variation or
It changes still within the protection scope of the invention.
