The specific embodiment
For clearly demonstrating the technical characterstic of this programme,, this programme is set forth below by a specific embodiment.
Embodiment one:
Be that to replace T5000 type diameter be that the installation method of the bottom roller of 800mm is example explanation the present invention to the 750mm bottom roller with QDW type rewinding machine diameter below.
With former bottom roller diameter is the 800mm coil paper, as Fig. 1, determines that under the situation of maximum paper roll and minimum paper roll invariant position diameter is the position of the bottom roller of 750mm.If do not consider other, as long as with diameter is the mobile backward when mounted 25mm of alternative bottom roller of 750mm, improving 25mm gets final product, as Fig. 2, but actual conditions are really not so, if install like this, the track 6 that move at refill center track 5 that moves and the refill center that former bottom roller is installed behind the alternative bottom roller of installation differs bigger, as shown in Figure 2, its disparity is 10.71mm, its center has exceeded the scope that remedies of eccentric thimble, needs the thimble of right in addition-2-refill to transform, and has so just strengthened work capacity and can be very loaded down with trivial details.Will reach best effect with the change of minimum so transform, key will guarantee that the variation of paper roll center motion track must not exceed the amount of the remedying 8mm of eccentric thimble.
It mainly also comprises the steps the present invention,
1), determine to substitute the center shaft position of bottom roller: the cylindrical of refill and batch the cylindrical of the paper roll of maximum gauge when at first determining to use former bottom roller, then, the cylindrical of refill and to batch the cylindrical of paper roll of maximum gauge all circumscribed when doing a tangent circles and making it and use former bottom roller, this tangent circle diameter is for substituting the diameter of bottom roller, the center of tangent circles is exactly the center that substitutes bottom roller, as shown in Figure 3
2), basis substitutes the center design of bottom roller and substitutes the bearing chamber that bottom roller cooperates;
3), according to the variation that substitutes bottom roller length and transmission axle journal, the size of design brake disc coupler;
4), determine transmission shaft migration included angle, the coupler that selection is suitable for;
