The support bracket 700 can move toward the support seat 200 to support the tablecloth after winding.

[0025] The above-mentioned convenient winding device for table cloth has a novel structure. The rotating frame 300 includes a rotating shaft 310, a frame plate group fixed on both sides of the rotating shaft 310, and a winding structure 400 is installed at the end of the frame plate group. The winding structure 400 is driven by an independent first motor 510, and the rotating frame 300 is driven by a second motor 520. The table cloth can be wound on both sides, thereby realizing the winding rotation, facilitating the disassembly and assembly of the table cloth roll and the winding roller, reducing the downtime and improving the production efficiency; wherein, the design and coordination of the push rod motor 610, the insert strip 620, the turntable 330, and the card slot 340 can lock the rotating frame 300 to ensure the overall load-bearing capacity and prevent the rotating frame 300 from rotating and tipping over; and the design of the support frame 700 can lock the table cloth roll that has been rolled up The support is convenient for disassembly and transfer, and the work efficiency is improved; more specifically, when the winding structure on one side completes the winding of the tablecloth, the tablecloth is cut off, and then the second motor is started, and the push rod motor is started at the same time to release the lock of the turntable, the second motor drives the rotating frame to rotate 90°, the push rod motor is reset and the turntable is locked, the staff moves the supporting frame into place, and then makes the push rod motor retract the piston rod, starts the second motor again, the rotating frame rotates 90°, so that the wound tablecloth roll falls on the supporting frame, and the push rod motor locks the turntable again; the staff first cooperates with the other winding structure with the tablecloth, starts the corresponding first motor, and winds it; then disassembles and removes the tablecloth roll, and replaces the corresponding winding roller to prepare for the next tablecloth roll.
