Specific embodiment
This utility model is described in detail below in conjunction with the accompanying drawings, when this utility model embodiment is described in detail, for ease of
Illustrate, represent that the accompanying drawing of device architecture can disobey general ratio and do partial enlargement, and the schematic diagram is example, its here
The scope of this utility model protection should not be limited.It should be noted that accompanying drawing using simplification in the form of and using it is non-accurately
Ratio, only to purpose that is convenient, clearly aiding in illustrating this utility model embodiment.
As shown in Figure 1, Figure 2 and Figure 3, the barrier film reel of the present embodiment includes inner core 1, outer tube 2, fixed pole 3 and can stretch
Contracting pole 4, inner core 1 and outer tube 2 are hollow cylinder, and inner core 1 is nested in outer tube 2, and inner core 1 and outer tube 2 are coaxially arranged.Outer tube
2 by fixed part 2-1 and movable part 2-2, and fixed part 2-1 and movable part 2-2 is radius identical cylinder, fixed part 2-1 with it is movable
Portion 2-2 is alternately disposed at the periphery of inner core 1, and fixed part 2-1 and movable part 2-2 surrounds annular, forms outer tube 2.Fixed part 2-1 and
Can coordinate for gap or be spaced between movable part 2-2 adjacent edge and coordinate, be i.e. it is outer that fixed part 2-1 and movable part 2-2 is formed
Cylinder can (fixed part and movable part interval set for continuous outer tube (fixed part and movable part are disposed adjacent) or discontinuous outer tube
Put).
Pole is provided between outer tube 2 and inner core 1, wherein, fixed pole 3 is set between fixed part 2-1 and inner core 1,
Telescopic support struts 4 are set between movable part 2-2 and inner core.One end of fixed pole 3 is fixed on inner core 2, the other end and fixation
Portion 2-1 is connected, and fixed part 2-1 is supported in into the periphery of inner core 1.One end of telescopic support struts 4 is fixed on inner core 2, the other end
It is connected with movable part 2-2, movable part 2-2 is supported in into the periphery of inner core 1.In the present embodiment, outer tube 2 by 2 fixed part 2-1 and
4 movable part 2-2 compositions, fixed part 2-1 is symmetricly set in the outside of inner core 1, and continuous setting two can between fixed part 2-1
Dynamic portion 2-2, has interval between adjacent moveable portion 2-2 and fixed part 2-1.
With reference to Fig. 4, the telescopic support struts 4 of the present embodiment include fixed sliding sleeve 4-1, interior slide bar 4-2 and the cunning that is connected
The elastic component 4-3 of set 4-1 and interior slide bar 4-2, the elastic component 4-3 of the present embodiment are spring, and spring housing is in fixed sliding sleeve 4-1 and interior
Outside slide bar 4-2, and one end is with fixed sliding sleeve 4-1 is connected, the other end is connected with interior slide bar 4-2.Interior slide bar 4-2 is arranged at fixed cunning
Cover in 4-1, and sliding sleeve 4-1 can be relatively fixed and move back and forth along own axes, so as to stretch out outside fixed sliding sleeve 4-1 or be reduced to fixation
In sliding sleeve 4-1, to change the length of telescopic support struts 4.When acting on without other external force, elastic component 4-1 stretches interior slide bar 4-2
Outside for fixed sliding sleeve 4-1.The present embodiment is arranged at fixed sliding sleeve 4-1 on inner core 1, interior slide bar 4-2 and movable part 2-2 phases
Even, but also fixed sliding sleeve can be arranged on movable part, interior slide bar is connected with inner core.Additionally, telescopic support struts can also be direct
Using elastic component.
Working condition of the present utility model is illustrated below：
When barrier film has just been wound on barrier film reel, state of the barrier film in relative relaxation will not produce very big tension force,
Interior slide bar 4-2 is stretched out in outside fixed sliding sleeve 4-1 under the elastic force effect of elastic component 4-1, so that movable part 2-2 and fixed part 2-
1 forms hollow cylinder, and now the external diameter of reel is equal to the external diameter of the cylinder formed with the diameter of fixed part；
When barrier film winding increase after, the membrane tension for gradually increasing overcomes the elastic force of elastic component 4-1, by interior slide bar 4-2 by
Gradually it is pressed into fixed in sliding sleeve 4-1, the length of telescopic support struts starts to shorten, so that movable part 2-2 is near spool axis
Direction movement, the external diameter of reel is little when the external diameter opposed diaphragm of reel just winds, barrier film winding terminate after, elastic component is pressed
Contracting telescopic support struts be reduced to it is most short, so as to receive the tension force that barrier film gradually discharges, make barrier film winding when itself exist tension force drop
To minimum, now reel is substantially in ellipticity.
Barrier film reel of the present utility model external diameter during winding barrier film can change with membrane tension, so as to avoid
Because membrane tension such as causes to be deformed in battery manufacturing procedure the phenomenon, the yield of lithium ion battery can be effectively improved.
