The roller guide seats 6 are groove structures, and the roller guide seats 6 are arranged in pairs. The primary transmission roller 2 is rotatably mounted on the winding device frame 1 through the ball bearing 5. The secondary transmission roller 3 is symmetrically arranged with the primary transmission roller 2. The winding roller shaft 4 is composed of a rotating shaft 8 and a winding drum 9. The winding drum 9 is fixedly mounted on the rotating shaft 8, and docking bearings 7 are fixedly mounted on both sides of the rotating shaft 8. The bearing outer ring of the docking bearing 7 is movably mounted on the roller guide seat 6. By setting a winding device for processing household sofa fabrics composed of the winding device frame 1, the primary transmission roller 2, the secondary transmission roller 3 and the winding roller shaft 4, the winding roller shaft 4 is driven to rotate by the friction of the primary transmission roller 2 and the secondary transmission roller 3 on the winding roller shaft 4, so that it is convenient for the staff to take out the rolled fabric roll.

[0039] A positioning groove 10 is provided on the arc surface of the winding drum 9, and a rotating rod 11 is rotatably installed between the side walls at both ends of the winding drum 9. A pressure plate 12 is integrally formed on the rotating rod 11, and a force plate 13 is integrally formed on the inner side surface of the pressure plate 12. The side surface of the force plate 13 is connected to the inner side wall of the winding drum 9 through an elastic rope 14. Both ends of the rotating shaft 8 are provided with mounting grooves 15, and a guide groove 16 is provided on the side wall of the mounting groove 15. A force rod 18 is movably installed in the mounting groove 15, and a support spring 17 is fixedly connected to the inner side surface of the force rod 18.
