Because Idle wheel is installed on the sliding support, be provided with stage clip between mobilizable sliding support and the fixed support, like this, after Idle wheel pushed against with synchronous band, when duplicating machine constantly became slack through using synchronous band for a long time, stage clip can continue to pass the slip sliding support, the Idle wheel that assurance is installed on the sliding support keeps pushing against with synchronous band constantly, promptly realize real-time regulated, constant tension, guaranteed the transmission efficiency of duplicating machine, improved working stability and accuracy.
As improvement, it also comprises at least one pin, and sliding support comprises first transverse slat, is penetrated with long kidney-shaped hole on first transverse slat; Fixed bearing comprises second transverse slat, second transverse slat is provided with and each pin tapped hole one to one, pin passes long kidney-shaped hole and screws in the corresponding tapped hole, like this, just realized the sliding fit of sliding support and fixed bearing, sliding support can move along the length direction of long kidney-shaped hole, and the length of long kidney-shaped hole has determined the amplitude of accommodation of this device.
As improving, pin is two again, and the tapped hole on second transverse slat is two also, utilizes two pins with travel(l)ing rest and fixed support installation, and its more reasonable stress can strengthen the stability of work.
As also improving, every pin is sheathed with a movable protecting jacket, and movable protecting jacket stretches in the long kidney-shaped hole, and like this, the many support and protections of movable protecting jacket make that the process of travel(l)ing rest sliding translation is more smooth and easy level and smooth between pin and long kidney-shaped hole.
As preferably, be fixed with starting stave on first transverse slat, starting stave is provided with first round tube hole; Be fixed with second riser on second transverse slat, second riser is provided with second round tube hole, be provided with an axis of guide between the starting stave and second riser, the axis of guide is provided with a position limiting convex ring, and axis of guide two ends are linked in respectively in first round tube hole and second round tube hole, compression spring sleeve is combined on the axis of guide, the two ends of stage clip push against with the position limiting convex ring and second riser respectively, and position limiting convex ring pushes against with starting stave under the effect of stage clip, and such is simple in structure, easy to assembly, reliable in function.
As further improvement, be penetrated with waist through hole on second transverse slat, screw and the duplicating machine shell of second transverse slat through passing waist through hole is spirally connected, like this, can regulate the mounting point of fixed support on the duplicating machine shell, enlarge the amplitude of accommodation of Idle wheel fixed position, make device better the regulating effect of Idle wheel.
