Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery diaphragm stretching equipment, and more specifically, to a chain clip device with adjustable longitudinal pulling ratio. Background Art

[0002] The transverse stretching machine is a device that shapes the lithium battery separator through transverse stretching and high-temperature drying. There are two sets of closed-loop tracks from the equipment entrance to the exit. Two sets of chain clip systems are provided on the tracks of the equipment. The lithium battery separator needs to be clamped by the chain clip system when passing through the equipment. The chain clip system transports the lithium battery separator when traveling along the track. Due to the tolerance gap between the chain clip systems, the gap will gradually increase during transportation, thereby generating stress, over-stretching the lithium battery separator and reducing the quality.

[0003] The utility model with publication number CN203543104U discloses a chain clip device with adjustable longitudinal stretch ratio for film stretching, including a plurality of chain clips, adjacent chain clips are connected by chains, and a first bearing is transversely arranged on the chain; the chain clip moves along a track, and the track includes a vertical track and a convex track. Through the change of the movement trajectory of the first bearing along the track, the chain is gradually bent from straight or gradually changed from bent to straight, and the spacing between adjacent chain clips gradually becomes smaller or larger, thereby changing the stretch ratio and effectively improving the film quality.

[0004] However, in the chain clip device with adjustable longitudinal pull ratio for film stretching with publication number CN203543104U, although the chain clip can gradually reduce or increase the distance between adjacent chain clips by changing the moving trajectory of the chain clip along the cam rail through a specific bearing; however, since the specific bearing in contact with the cam rail is inside the chain clip, the internal space of the chain clip is too small and the operation is troublesome when the cam rail adjusts the height position, and the longitudinal pull ratio cannot be corrected in time when transmitting a diaphragm with a larger or smaller deformation.

The spacing between the chain clip bodies 100 and the chain clip bodies 100 is determined by the center distance between the two adjacent first chain pieces 1021. When the chain clip device travels on the straight section of the vertical rail 200, the chain structure of the chain The chain is relatively parallel to the straight section track. When passing through the first guide rail 301 and the second guide rail 302, the axial ends of the first chain pin 1023 connect the bearings with the track surfaces of the first guide rail 301 and the second guide rail 302, so that the chain is gradually bent from a parallel state, and the spacing between the chain clips changes from large to small, thereby reducing the stress generated by the lithium battery diaphragm during operation.
