Disk is movably disposed in pilot hole.
Further, the one end of the pilot hole away from conical blocks is equipped with groove, is fixed with limited block on the groove, institute
State the first chuck and be equipped with the notch that can house limited block.
Further, speed regulating motor, first rotating shaft, controller and encoder, the speed regulating motor driving first are further included
Shaft rotates, and the first rotating shaft and the second shaft are installed in the second shaft by gear drive, the encoder, the control
Device processed is electrically connected with speed regulating motor and encoder respectively.
Further, the cylinder is connected by shaft coupling with the second shaft, and the shaft coupling is defeated including being fixed on cylinder
Connector sleeve in outlet and the connection ring for being arranged and being fixed in the second shaft, the connector sleeve include base portion and two limits
Position portion, described two limiting sections are separately positioned on the opposite both sides of base portion, accommodating second shaft are formed between two limiting sections
The annular groove of connection ring cooperation is equipped with space and two limiting sections.
Further, described two limiting sections are made of elastic material.
Beneficial effect is:Compared with prior art, a kind of unreeling structure, the first chuck in converter is controlled by cylinder
Telescopic lifting, realizes the clamping and release of pole piece, simplifies pole piece replacement operation.
Brief description of the drawings
The embodiment of the present invention is described in further detail below in conjunction with attached drawing, wherein:
Fig. 1 is the structure diagram of unreeling structure of the present invention;
Fig. 2 is the structure diagram for removing unreeling structure after stent in Fig. 1;
Fig. 3 is the connection diagram of converter of the present invention and the second shaft;
Fig. 4 is the connection diagram of cylinder of the present invention and the second shaft.
Embodiment
As Figure 1-Figure 4, a kind of unreeling structure, including stent 1, the second chuck 2, cylinder 3, the second shaft 4 and conversion
Device 5, the cylinder 3 are arranged on one end of the second shaft 4 and promote the second shaft 4 to be moved along the axis direction of the second shaft 4;Institute
Stating converter 5 includes sleeve 51,52 and first chuck 53 of conical blocks, and the sleeve 51 and cylinder 3 are installed on stent 1, described
Second chuck 2 is fixed on sleeve 51, and the conical blocks 52 are fixed in the second shaft 4, and the sleeve 51 is equipped with accommodating circular cone
The cavity of the activity of block 52, the periphery of sleeve 51 are equipped with the pilot hole of connection cavity, and first chuck 53 has inclined-plane, institute
The inclined-plane for stating the first chuck 53 is fitted on the taper surface of conical blocks 52 and the first chuck 53 is movably disposed at pilot hole
It is interior.Cylinder 3 promotes the second shaft 4 to be moved along the axis direction of the second shaft 4, be fixed on conical blocks 52 in the second shaft 4 with
The second shaft 4 to move, so that the first chuck 53 being crimped on conical blocks 52 is along the axis direction perpendicular to the second shaft 4
It is mobile.When first chuck 53 rises, the first chuck 53 and the second chuck 2 clamp material, when the first chuck 53 declines, unclamp thing
Material, is conveniently replaceable.It is that can also increase by the 3rd chuck when the material size used is larger, the 3rd chuck is movably set in sleeve
On 51 and between the first chuck 53 and the second chuck 2, material, the first chuck are clamped by the 3rd chuck and the second chuck 2
53 are pressed on the 3rd chuck.
Further, the one end of the pilot hole away from conical blocks 52 is equipped with groove, and limited block is fixed with the groove
54, first chuck 53 is equipped with the notch that can house limited block 54.Limited block 54 prevents the first chuck 53 from departing from sleeve 51.
Further, speed regulating motor 6, first rotating shaft 7, controller and encoder are further included, the driving of speed regulating motor 6 the
One shaft 7 rotates, and 7 and second shaft 4 of first rotating shaft is installed in the second shaft 4 by gear drive, the encoder,
The controller is electrically connected with speed regulating motor 6 and encoder respectively.The position of the second shaft 4 is sensed by encoder, judgement is
It is no to need to be fed, the blowing of pole piece is controlled by speed regulating motor 6.Speed regulating motor 6 controls the blowing of pole piece, compared to passive blowing,
Dispensing speed can be more precisely controlled, reduces the stretcher strain amount of pole piece.
Further, the cylinder 3 is connected by shaft coupling 8 with the second shaft 4, and the shaft coupling 8 includes being fixed on gas
Connector sleeve 81 on 3 output terminal of cylinder and the connection ring 82 for being arranged and being fixed in the second shaft 4, the connector sleeve 81 include
Base portion and two limiting sections, described two limiting sections are separately positioned on the opposite both sides of base portion, are formed and held between two limiting sections
Put the annular groove that the cooperation of connection ring 82 is equipped with the space of the second shaft 4 and two limiting sections.By using shaft coupling 8,
During so that the second shaft 4 rotating, cylinder 3 is not interfered with, and cylinder 3 can easily promote the second shaft 4 along second turn
The axis direction movement of axis 4.
Further, described two limiting sections are made of elastic material.
The above embodiments are merely illustrative of the technical solutions of the present invention and is not limited, all without departing from the present invention
Any modification of spirit and scope or equivalent substitution, it should all cover in the range of technical solution of the present invention.
