▎ 摘　　要

NOVELTY - The device has a limiting block that is fixedly connected to a first sliding block. The bottom end of a pull rod is locked inside the limiting block. One end of four first connecting rods are rotatably connected to the inside of the first sliding block. The other end of the first connecting rod is rotatably connected with a first fixing block. Two second sliding blocks are fixedly connected to the side wall of a first rotating shaft. One end of four second connecting rods are rotatably connected to the inside of the second sliding block. The other end of the second connecting rod is rotatably connected to a second fixing block. The first fixing block and the second fixing block are both fixedly connected to the side wall of the same roll plate (21). An auxiliary mechanism (4) is provided at one end of a device main housing (1) and a moving mechanism (5) is provided at the bottom end. USE - Graphene thin material winding device for fixing storage tubes of different sizes. ADVANTAGE - The storage tube is placed on the outside of the four coils, and the turntable is turned, so that the four coils spread out and fix the storage tube. The graphene thin material is fixedly connected to the side wall of the receiving cylinder after passing through the auxiliary mechanism, and the differential motor is energized. The storage tube is rotated to store the graphene thin material. The turntable is turned in the opposite direction to shrink the coil inward, after the storage is completed, so that the roll plate does not interfere with the storage tube. The use mode is more flexible and convenient. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of the graphene thin material winding device.
