Embodiment
With reference to specific accompanying drawing, the utility model is described in further detail.
Pre-roll is carried out using the volume pin as shown in Fig. 2-1, Fig. 2-2, its barrier film wound comes from the both sides of volume pin, necessarily makes
It is tightened up into the barrier film between pre-roll pin 1 and battery core 5, influences the quality of battery core 5.
Volume pin described in the utility model can allow for barrier film to be skidded in pin is rolled up when carrying out barrier film pre-roll, avoid drawing bad
Barrier film.
As shown in Fig. 3-1, Fig. 3-2, Fig. 3-3, stitch 1011 and barrier film 8 of the volume pin described in the utility model in volume pin originally
The place that can be in contact in winding is provided with rotating shaft 103, and when rolling up pin progress rotate counterclockwise winding, barrier film 8 is in volume pin
Interior to skid, the barrier film of volume pin winding just comes from the less side of pulling force, makees when using volume pin described in the utility model
For pre-roll pin 1 when can avoid the barrier film pulling force between pre-roll pin 1 and battery core 5 excessive.
, therefore, in actual winding process can be with because two stitch 1011 in the utility model do not have clamping function
Following operation：After rolling up pin and having wound 180 degree, the substantially situation of stitch 1011 and barrier film 8 in pin is rolled up as shown in figure 3-2, now,
Barrier film 8 can be compressed by hold-down roller 6, cutting knife 7 cuts off barrier film 8, and under the compression of hold-down roller 6, volume pin continues to wind, when cutting
When the barrier film 8 of the top of knife 7 is pushed down by the barrier film that left side will be wound, barrier film completes self-locking, and hold-down roller 6 can unclamp afterwards, rolls up
Pin wound upon itself.
In addition it is also possible to as shown in Fig. 3-3, volume pin is made to wind 360 degree, now, the barrier film wound before rolling up on pin is
The barrier film that will be wound compresses, then the frictional force between barrier film and barrier film make it that in winding process afterwards barrier film will not
Unclamp.
The specific set-up mode of volume pin described in the utility model is as shown in Fig. 4-1~Fig. 4-3, Fig. 5-1~Fig. 5-2.Roll up pin
It is main to include volume Aculeata 101（As shown in Fig. 4-1~Fig. 4-3）With volume needle section 102（As shown in Fig. 5-1~Fig. 5-2）, roll up pin
Afterbody 101 and volume needle section 102 can engage blending bolt locking.Rolling up Aculeata 101 is included in cylindrical first connecting portion
1010 and section in two fan-shaped stitch 1011, two one end of stitch 1011 be fixedly attached to first connecting portion 1010 or with
First connecting portion 1010 is integrative-structure, and two other ends of stitch 1011 are provided with the first card that can be engaged with volume needle section 102
Socket part 1012, also in sector, the radius of the first Access Division 1012 is less than the horizontal stroke of stitch 1011 for the cross section of the first Access Division 1012
The fan-shaped radius in section, is provided with the hole of fixed rotating shaft 103, the one end of rotating shaft 103 is fixed to the hole between two stitch 1011
In, the other end of rotating shaft 103 is fixed to volume needle section 102（As another embodiment of the present utility model, two rotating shafts 103
Both ends can also be set directly on stitch 1011, can only can ensure that rotating shaft 103 can rotate）.Volume needle section 102 is wrapped
Second connecting portion 1021 and section in cylinder are included in two fan-shaped the second Access Divisions 1022, the one of the second Access Division 1022
End is fixed to second connecting portion 1021 or is integral with second connecting portion 1021, is set in the second Access Division 1022 and volume pin
The buckling groove 1023 of the clamping of the first Access Division 1012 in afterbody 101, on the first Access Division 1012 and the second Access Division 1022
Relevant position is provided with locking screw holes 1024, for locking the first Access Division 1012 and the second Access Division 1022.
Rotating shaft 103 on the volume pin can set two, as shown in Fig. 3-1~Fig. 3-3, can also set four, such as
Shown in Fig. 4-1~Fig. 4-3（Four holes are the mounting hole of installation rotating shaft 103 in Fig. 4-1）.
Above-mentioned volume pin is arranged on up- coiler, using the winder winding around battery core.The up- coiler is in winding battery core
