The volume needle device that the square lithium battery cell of this structure is reeled, when work, because but axially the doing of push rod relative rotation axi that is installed on the rotating shaft advanced and setback, thereby make with its clamp jaw holder of volume pin holder, two halves that remains the two halves that directly contact or keep by the third party linking to each other along doing in opposite directions or reverse motions with the perpendicular track of push rod, thereby make volume pin fixed thereon realize doing expansion and contractile motion, clamp jaw is done and is clamped and disengaging movement, when the expansion of volume pin, clamp jaw clamp, can reel; When the volume pin shrinks, clamp jaw separates, just the electric core that winds can be withdrawed from.Because volume pin, volume pin holder, clamp jaw, clamp jaw holder are to be installed on the rotating shaft by track all, and track and push rod are installed on and can follow rotating shaft on the rotating shaft and rotate together, when rotating shaft rotates, just can realize just negative electrode, anode and three kinds of material winding shapings of barrier film.
The front end of described push rod is the variation that is the Width that waist shrinks, two is roomy, or for being the variation of the Width that waist is roomy, shrink at two.
The volume pin holder of two halves and two halves clamp jaw holder keep the third party who links to each other to be roller by the third party with push rod, described roller be installed on respectively two halves volume pin holder and the clamp jaw holder of two halves on, described roller remains with push rod and contacts, push rod is done and is advanced or setback, and the volume pin holder that drives two halves by roller is done opposite or move toward one another with two halves clamp jaw holder in the direction vertical with the pushrod movement direction.
The contraction of the front end waist of described push rod or roomy length equal or approach to roll up roller on the pin holder and the length between the roller on the clamp jaw holder, should make waist location, end position that is in push rod that roller on the volume pin holder and one on the roller on the clamp jaw holder are in push rod when push rod is installed.
Those can do straight-line power drive and advance and setback to realize doing described push rod by cylinder, nut screw mandrel etc.
The extension spring of the volume pin holder of described connection two halves is a return spring.
The extension spring of the clamp jaw holder of described connection two halves is a fastening spring.
In sum, the following compared to existing technology advantage of the utility model:
The utility model adopts particular structure, can make that coiling is preceding, utilize the motion of push rod to make clamp jaw open automatically and reel material clamping, volume pin automatically when reeling; Utilize the motion of push rod to make clamp jaw unclamp, roll up pin automatically behind the coiling and shrink automatically, the electric core that is wrapped on the volume pin is separated with the volume pin, can conveniently make electric core withdraw from separation, the automation of the electric core that helps realizing reeling.
