[0007] As a further setting of the utility model, the folding arm includes a connecting arm, first and second arm rods are respectively hinged to the two ends of the connecting arm, the first arm rod is connected to the nut seat, and the second arm rod is connected to the arc-shaped piece.

[0008] As a further setting of the utility model, a sliding piece is arranged on the second arm rod, four sliding grooves are formed in the radial direction on the flashboard, and the sliding piece penetrates the sliding grooves.

[0009] As a further setting of the utility model, the sliding sheet is provided with a plurality of connecting pins, and the connecting pins are provided with ball bearings at both ends for abutting against the baffle disc.

[0010] As a further setting of the utility model, the threaded screw rod is connected with a handle at one end away from the baffle disc.

[0011] Compared with the prior art, the utility model has the beneficial effects that:

[0012] In use, the four arc-shaped sheets can jointly form a cylindrical structure for the reel to enter, and play a role in supporting the fabric roll. BRIEF DESCRIPTION OF DRAWINGS

[0017] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0018] Please refer to Figure 1As shown, a fabric unwinding frame, including a support 1, a unwinding mechanism is rotatably connected on the support 1, the unwinding mechanism includes a baffle disc 2, the cross section of the baffle disc 2 is circular, and four arc-shaped pieces 3 are slidably connected on the baffle disc 2, the four arc-shaped pieces 3 are distributed in cross symmetry with the center of the baffle disc 2 as the center, a driving mechanism connected with the arc-shaped pieces 3 is arranged on the baffle disc 2, the driving mechanism is used for driving the four arc-shaped pieces 3 to move synchronously inward or outward along the radial direction of the baffle disc 2, then when the unwinding frame is used, the four arc-shaped pieces 3 can jointly form a cylindrical structure for the reel to enter, and play a role of supporting the fabric roll, and since the positions of the four arc-shaped pieces 3 can be synchronously adjusted, the distance between the arc-shaped pieces 3 can be adjusted according to the diameter of the reel, so that the whole cylindrical structure expands or contracts accordingly, until it can match the diameter of the reel, thereby avoiding the situation of size mismatch, and flexibly adapting the installation of fabric rolls of different sizes, and having good applicability.
