The copper foil paper axis tube core 10, equipment addendum cone 30 and crossover sub 20 are located on same axis.
It should be noted that outer wall is used to wind at least one circle copper foil to the diameter of the copper foil paper axis tube core 10 around, when
When it is rotated, copper foil (i.e. the substrate of battery pole piece) will be discharged, realization unreels function.
It the right part of the equipment addendum cone 30, can for being connected with external driver device (such as output shaft of motor)
Under the driving of external driver device, rotating clockwise or counter-clockwise for front and back is carried out in the longitudinal direction.Here, specific connection knot
Structure is not due to being unfolded to state for the prior art.
In the present invention, in specific implementation, the copper foil paper axis tube core 10 is right-end openings, hollow structure；
The left end of the crossover sub 20 is connected to 10 the inside of copper foil paper axis tube core.
In the present invention, in specific implementation, the crossover sub 20 includes that the tube core of cross direction profiles is inserted into 23 He of column
Vertical distribution, cylindrical connection locating piece 24；
The tube core insertion column 23 is located at the left side of connection locating piece 24；
The front and rear sides of the tube core insertion column 23 are respectively provided with a crossover sub clamping block 25, and (as a card slot is matched
Part)；
The copper foil paper axis tube core 10 has tube core card slot 11 in position corresponding with the crossover sub clamping block 25；
Shape, the size matching corresponding with shape, the size of the tube core card slot 11 of the crossover sub clamping block 25；
The crossover sub clamping block 25 is clamped with 11 phase of tube core card slot.
In specific implementation, the tube core insertion column 23 is inserted into inside the inner cavity of the copper foil paper axis tube core 10.
In specific implementation, there is the crossover sub 20 right-end openings, cross direction profiles addendum cone to cooperate inner hole 21；
The addendum cone cooperation inner hole 21 is located at 24 the inside of tube core insertion column 23 and connection locating piece；
The two sides up and down of the connection locating piece 24 are respectively provided with the crossover sub card slot 22 an of cross direction profiles；
The crossover sub card slot 22 is connected with the right end of addendum cone cooperation inner hole 21；
