Embodiment describes in detail
One is used for the flexible drive system that cylinder grinds on the powder machine and comprises: a pair of 10,11 and one of first belt wheels that preferably have the dentate gyrus perimeter surface have the flexibility of dentation complementary structure to be with 12 on the two sides.
Another supporting housing 17 is fixed on cylinder and grinds on the powder machine frame 16, and another roller of milling on it (not showing) rotates around axle 18.
To see that in Fig. 1 power band 12 is twining first pair of belt wheel 10,11, can rotate them in the opposite direction synchronously like this.Grind on the powder machine at typical cylinder, will pivotally regulate supporting housing 14 with respect to frame 17 and make roller on demand or close or from the roll gap of setting between the roller surface.
An engaging mechanism is provided usually, when having raw material to flow in the roller, they is not separated far away.
In order to keep driving tension force appropriate in the belt 12, also the dentation idler 19 that is being twined by belt is installed in rotation on 21 on pair of parallel support around axle 20 and makes idler 19 to rotate between them, support 21 pivotally is installed on the latch 22, and usually latch 22 is fixed on cylinder and grinds the axis that powder machine frame upper edge is parallel to belt wheel 10,11 and 19 and stretch out.
At the opposite end of support 21, there is take-up device 23 to set belt tensions, promptly grind the pivot location that powder machine frame 16 is set supports 21 with respect to cylinder, take-up device is contained in cylinder and grinds on the powder machine frame 16.
Take-up device 23 comprises a spring 24, and it plays cushioning effect and makes cylinder grind powder machine roller separately to adapt to any big solid objects that unexpectedly flows in the roll gap.
According to first example of the present invention, latch 22 is not to be fixed on cylinder to grind on the powder machine frame, but is fixed on second support 25, second support 25 pivotally be installed in cylinder grind on the pivot 26 on the powder machine frame around with axle 13,18 and 20 rectangular pivots.At support 25 opposite ends is that a linear adjusting device 27 is used for regulating the link of support 25 with respect to inside or outside the moving of cylinder stone roller powder machine frame, promptly around pivot 26 rotations.In this mode, can regulate the angle of the axis of latch 22 with respect to axle 13 and 18, and the relative angle of regulating shaft 20 successively.This adjusting can be used for controlling the track of power band 12 with respect to the surface of belt wheel 10 and 11, thereby avoids its horizontal slip.
Referring now to Fig. 2, in second example, belt 12 twines second idler 28 of dressing on support 21.In this embodiment, the latch on the second support 25A 22 forms the rotating shaft of second idler 28.It is controlled again around the angle adjustment of pivot 26 that the track of belt can be gone up latch 22 by support 25A.In this embodiment, idler directly is contained on the latch 22.
Fig. 3 has represented to grind pivotally connected (on the 26) mode of the support 25 of least significant end of powder machine frame 16 or 25A and in the adjusting device 27 of most significant end at cylinder.
Referring now to Fig. 4, can see that idler 19 and 28 is installed on the support 21A, all twined by belt 12, and usually on belt wheel 11 and below separately.Support 21A provides the optimization of belt 12 on belt wheel 11 to twine.In this embodiment, the idler 19 below top idler 28 is contained on the latch 22 simultaneously is contained between the support 21A that is connecting take-up device 23.
Fig. 5 has represented that so-called pair of high cylinders grind the powder machines, and wherein two pairs of rollers are contained in respectively on the axle 30,31, make the raw material that is ground pass through the wherein roll gap of a pair of roller, flow into another roll gap to roller then.
In this embodiment, device shown has been duplicated by dual among Fig. 2.With preceding identical, the second support 25A is installed on the pivot 26, and the another one second support 25B is installed in cylinder at its top end and grinds on the other pivot 32 on the powder machine frame 16, has one to regulate bolt 33 in its lower end.
The present invention will can not be limited to this paper elaboration and illustrated example.It is that idler should be contained in one and can adjust on the axle of angle with respect to the axis of first pair of belt wheel 10 and 11 that major technology of the present invention requires, and preferably is contained on the latch that directly is connected on the frame.
Require only to make the track that trickle angle adjustment can guarantee that belt is accurate on belt wheel 10,11, continue, proofread and correct of the slip of expected or unexpected belt simultaneously to one side or another side.
Typically, belt wheel 10,11 and 19 width, and the width of power band 12 approximately is 120mm.
Though the present invention describes with reference to grain mill, but any device that contains an a pair of belt wheel and a flexible dynamic band can comprise device of the present invention, be used for respect to one of them, the belt wheel axis that twined by the power band, the angle of regulating the idler axis.A similar device can be used in chain drive system, but is used in dried belt transmission system especially.
