Described each clamping plate are provided with for regulating the adjusting slotted hole of spacing between the wheel shaft of two Idle wheels, and Idle wheel is assemblied on clamping plate by being threaded onto the construction bolt regulating in slotted hole.
On described each clamping plate, be also provided with for coordinate with construction bolt thrust, two Idle wheel spacing become large retaining and adjust screw when preventing work.
Described Idle wheel is bearing.
Chain drive of the present invention adopts following technological scheme: chain drive, comprise Transmitted chains, also comprise chain tightener, this chain tightener comprises spaced two clamping plate, between two clamping plate, be provided with for the both sides of Transmitted chains thickness direction being carried out to two Idle wheels of tension, Idle wheel encloses and has formed the passage passing through for Transmitted chains together with clamping plate.
Described each clamping plate are provided with for regulating the adjusting slotted hole of spacing between the wheel shaft of two Idle wheels, and Idle wheel is assemblied on clamping plate by being threaded onto the construction bolt regulating in slotted hole.
On described each clamping plate, be also provided with for coordinate with construction bolt thrust, two Idle wheel spacing become large retaining and adjust screw when preventing work.
Tobacco scrap prodn device of the present invention adopts following technological scheme: tobacco scrap prodn device, comprise chain drive, described chain drive comprises Transmitted chains, described chain drive also comprises chain tightener, this chain tightener comprises spaced two clamping plate, between two clamping plate, be provided with for the both sides of Transmitted chains thickness direction being carried out to two Idle wheels of tension, Idle wheel encloses and has formed the passage passing through for Transmitted chains together with clamping plate.
Described each clamping plate are provided with for regulating the adjusting slotted hole of spacing between the wheel shaft of two Idle wheels, and Idle wheel is assemblied on clamping plate by being threaded onto the construction bolt regulating in slotted hole.
Beneficial effect of the present invention: while adopting this chain tightener, Idle wheel can carry out tension to it in the both sides of the thickness direction of Transmitted chains, can avoid the instantaneous problem that damaged by the excessive relevant device bringing of load of Transmitted chains that cause on limit that loosens, tighten causing due to monolateral tensioning, this chain tightener can make the both sides tensioning of Transmitted chains, when Transmitted chains rotates backward, also can not be damaged.
Further, by regulating slotted hole, the spacing between the wheel shaft between adjustable two Idle wheels, can effectively avoid tensioning excessively and cross and send phenomenon.
Further, during use, by retaining, adjust screw and can prevent that the spacing increase between Idle wheel from affecting the tension to Transmitted chains.
