Rewinding machine, is a kind of for stationery, mica tape, thin film special equipment, and paper machine is produced by its purposes
Paper roll (referred to as paper roll) carries out rewinding successively, and paper is made finished paper after rewinding and dispatched from the factory.At present, rewinding machine exchange passes
Dynamic replacement DC Transmission has become development trend in papermaking machinery industry.
But, between refill and rewinding machine power transmission shaft, use 3 cun of chucks 3 to be converted into 6 cun of chucks the most in process of production
Location, seat 4 both sides is fixing to be rotated, as it is shown in figure 1,3 cun of chucks 3 are connected with drive shaft 1,6 cun of base of the carrier head 4 are connected with refill 2,3 cun
Chuck 3 is connected with 6 cun of base of the carrier head 4, thus makes to there is fit clearance between 3 cun of chucks 3 and 6 cun of base of the carrier head 4, along with
The increase of access times, abrasion can strengthen, because this gap also can progressively strengthen；Refill 2 hole size manufacture process exists partially
Difference, causes there is gap between refill 2 and 6 cun of base of the carrier head 4.The cumulative of two above gap reaches to a certain degree to may result in paper
Volume vibration exceeding the standard, the VIBRATION DESIGN setting of current coil paper is at 30mm/s, but the existence in two above gap so that coil paper
Vibration values is far longer than 30mm/s, and maximum can reach 170mm/s unexpectedly, thus causes the dead stricture of vagina of paper roll during generating tight
Weight so that enterprise's defective products whole year economic loss reaches millions of unit.
Therefore, a kind of vibration values that can reduce coil paper, the chuck solving coil paper dead stricture of vagina phenomenon urgently occurs.
Utility model content
In order to overcome above-mentioned the deficiencies in the prior art, this utility model provides a kind of vibration values that can reduce coil paper,
Solve the tapering collet expander of coil paper dead stricture of vagina phenomenon.
For reaching above-mentioned purpose, this utility model solves its technical problem and be the technical scheme is that
A kind of collet expander, for connecting drive shaft and the refill of rewinding machine, it is characterised in that including:
Connecting clip seat, the outer surface of described connecting clip seat is connected with described refill, and described outer surface circumferentially sets
Having at least one for placing the groove of following flexible member, described connecting clip seat is provided with a junction, described company vertically
The longitudinal section meeting portion is a tapering, and described connecting clip seat includes at least 2 cartridge unit；
Transition joint, described transition joint is connected with described drive shaft, described transition joint and described connecting clip seat
Connecting portion is connected；
Flexible member, described flexible member is positioned in described groove, for described cartridge unit is spliced into connection folder
Headstock.
Further, described cartridge unit is circumferentially with connecting groove, and described connecting groove is arranged at the both sides of circumference, also
Including at least 2 connecting plates, described connecting plate is positioned in described connecting groove, is used for making adjacent two chuck circumferences connect.
Further, described connecting plate is provided with two mounting holes.
Further, the one during the cross section of described connecting portion is circle, ellipse, regular polygon.
Further, the cross section of described connecting portion is octagon, and the cross section of described transition joint is octagon.
Further, described flexible member is spring anchor ear.
Further, the end face of described cartridge unit is provided with circumferentially distributed hole.
Further, described transition joint and described connecting clip seat coaxial cooperation.
Technique scheme is used to provide the benefit that: by using cartridge unit to be spliced into connecting clip seat, outside dependence
At surface groove, flexible member controls to expand compression, thus eliminates the gap between base of the carrier head and refill, transition joint be connected
Base of the carrier head uses taper fit, thus eliminates the gap between transition joint and jointing, simple in construction, greatly reduces paper
The vibration values of volume, thus avoid the phenomenon of the dead stricture of vagina of paper roll, improve production efficiency, greatly reduce the production cost of enterprise.
