State.Fig. 6 is the schematic flow sheet that roller swells of processing of the harmomegathus adjustable type cutter arrangement in illustrated embodiment, harmomegathus regulation
Formula cutter arrangement is placed along gravity direction from top to bottom, similarly, since along circumferentially disposed three the processing roller 3 of holding cylinder 1
Position different, from not resulting in, each processing roller 3 movement locus when swelling is different, at self gravitation and drive division 2
Under driving effect, each processing roller 3 is the most gradually switched to retraction shape by the state of swelling according to the flow process shown in Fig. 6
State.Although the processing roller 3 of diverse location swell route and retraction route is different, but each due on drive division 2
It is identical that the portion that swells 21 in individual harmomegathus regulation portion and retraction portion 23 are in the time of each position, so each processing roller 3
The state that swells described in being in is consistent with time during retracted mode.
It is pointed out that shown in Fig. 5 and Fig. 6 processing roller 3 swell and retraction process is only this harmomegathus adjustable type
The described rotation axis of cutter arrangement and gravity direction situation time vertical, when this harmomegathus adjustable type cutter arrangement is according to its other party
When formula is arranged each processing roller 3 swell and route of retracting can be different with diagram route, but due to holding cylinder 1, drive
Dynamic portion 2 and the peculiar profile of processing roller 3 so that the time that swells of processing roller 3 is to maintain consistent with the retraction time.
It is understood that during for only processing roller 3, it is possible to by the telescopic mouth in holding cylinder 1
The relevant position of 11 arranges guiding surface 12, arranges with guiding surface 12 to the second corresponding flat connecting section on drive division 2
24 guide swelling and retracting of processing roller 3.In like manner, it is possible to the diameter of a processing roller 3 is set greater than retraction portion
Maximum radial gap size between 23 and the inner peripheral surface of holding cylinder 1.
