[0031] like Figure 1-Figure 5 As shown, a composite material rewinding device includes: a bracket 1, a first fixed plate 11 is provided on the bracket 1, two first slide grooves 12 are opened on the first fixed plate 11, and the two first slide grooves 12 are arranged in parallel; a universal wheel 6 is connected to the bottom of the bracket 1 to facilitate manual movement.

[0032] The unloading shaft 21 is rotatably connected to the upper part of the first fixed plate 11, and one end extends to one side of the first fixed plate 11. One end of the second fixed plate 13 is fixed to the side wall of the first fixed plate 11, and the second fixed plate 13 is arranged perpendicular to the first fixed plate 11.

[0033] The receiving shaft 31 is rotatably connected to the upper part of the first fixed plate 11, one end of which extends to one side of the first fixed plate 11 and is arranged parallel to the unwinding shaft 21, and the receiving wheel 32 is connected to the receiving shaft 31; a plurality of second sliding grooves 34 are provided on the side wall of the receiving shaft 31, and a plurality of first protrusions are provided on the inner wall of the receiving wheel 32, and the second sliding grooves 34 and the first protrusions are used to fix the receiving wheel 32 to the receiving shaft 31; a scale is also provided on the receiving shaft 31, and then after the first protrusion of the receiving wheel 32 is matched with the second sliding groove 34 on the receiving shaft 31, the receiving wheel 32 is pushed along the second sliding groove 34 to a position parallel to the material to be rolled 24. Here, the first protrusion and the second sliding groove 34 cooperate with each other, which can fix the receiving shaft 31 and the receiving wheel 32 well together, and the number of the first protrusion and the second sliding groove 34 are consistent.
