The device comprises two side chassis, each with a swing arm on its side. A telescopic cloth reel is located between the two swing arms. The swing arm on one side of the chassis is equipped with an opening and closing member for inserting and removing the cloth reel. After loosening a bolt, the opening and closing member opens, leaving an open area between the opening and closing member and the swing arm 4 for removing the cloth reel. After tightening the bolt, the opening and closing member closes, forming a sealed area for the cloth reel and securing it with the swing arm, allowing for removal and installation of the cloth reel.

The bottom end of the movable groove 160 extends along its length to the inner wall of the connecting hole 150, and the bottom end of the movable groove 160 is connected to the connecting hole 150.

[0045] Reference Figure 5 and Figure 6 The lifting assembly 500 includes a screw rod 510, a first motor 520, and a slider 530. The length of the screw rod 510 is consistent with the vertical direction. The two ends of the screw rod 510 along its length are rotatably connected to the corresponding side inner walls of the movable groove 160. The first motor 520 is connected to the frame 100 and is located above the screw rod 510. The output shaft of the first motor 520 passes downward through the top inner wall of the movable groove 160 in the vertical direction, and the output shaft of the first motor 520 is connected to one end of the screw rod 510.

[0046] The first motor 520 drives the screw rod 510 to rotate, thereby driving the slider 530 to move in the vertical direction. The supporting block 400 follows the slider 530 to move in the vertical direction, and makes the winding roller 200 approach or move away from the discharge port 120, thereby facilitating the replacement of the winding roller 200.

The guide plate 700 is used to separate the discharge port 120 into a discharge channel 121 and a clearance port 122. One end of the guide plate 700 is rotatably connected to the inner wall of the discharge port 120 along its length direction. The guide plate 700 is hinged with a rotating rod 710, and the other end of the rotating rod 710 is hinged with a moving block 720. The length direction of the moving block 720 is consistent with the length direction of the slider 530, and the moving block 720 is slidably connected to the inner wall of the bottom of the clearance port 122 along its length direction. The frame 100 is connected to a pushing assembly 800, which is used to push the moving block 720 along the length direction of the slider 530 and enable the rotating rod 710 to drive the guide plate 700 to rotate.

[0049] After winding is completed, the guide plate 700 rotates so that the end of the guide plate 700 away from the connection hole 150 is tilted downward, the supporting block 400 approaches the discharge channel 121, and the fourth motor 531 drives the supporting block 400 to rotate, so that the top opening of the placement slot 410 is positioned toward the discharge channel 121. The winding roller 200 falls onto the guide plate 700 and moves along the guide plate 700, thereby facilitating the winding roller 200 to move away from the frame 100 and facilitate the discharge of the winding roller 200. When installing a new winding roller 200, the supporting block 400 is placed in the connection hole 150, and the end of the guide plate 700 away from the connection hole 150 is tilted upward, thereby facilitating the winding roller 200 to move along the guide plate 700 and fall into the placement slot 410.
