A bevel gear plate 21 is fixedly connected to the surface of the screw rod 20. The screw rod 20 rotates and penetrates the empty box 2. The driving mechanism 6 cooperates with the bevel gear plate 21 to drive the screw rod 20 to rotate. The moving mechanism 16 is arranged on the surface of the screw rod 20. A cavity is provided inside the moving mechanism 16. An auxiliary mechanism 18 is installed inside the cavity. The inside of the moving mechanism 16 is rotatably connected to an extrusion frame 19. A baffle 24 is fixedly connected above the surface of the advertisement frame 1. The baffle 24 can block the top of the advertisement paper 14.

[0027] The driving mechanism 6 includes a motor 61, a rotating shaft 62 and a bevel gear 63. The motor 61 is fixedly connected to the bottom of the inner wall of the storage box 5. One end of the rotating shaft 62 is fixedly connected to the output shaft of the motor 61. The rotating shaft 62 rotates and passes through the top of the empty box 2. The bevel gear 63 is fixedly sleeved on the surface of the rotating shaft 62. The top plate 7 is fixedly connected to the bottom of the rotating shaft 62. The bevel gear disk 21 is meshed with the bevel gear 63. The staff starts the motor 61, and the rotating shaft 62 rotates to drive the top plate 7 to rotate. At the same time, the bevel gear disk 21 and the bevel gear 63 cooperate to drive the screw rod 20 to rotate, thereby driving the winding shaft 12 to rotate while the screw rod 20 rotates, so as to roll up the advertising paper 14.

[0028] The adjusting mechanism 8 includes a guide rod 81, an adjusting plate 82 and a compression spring 83. The guide rod 81 slides through the top plate 7.

The two ends of the compression spring 83 are respectively fixedly connected to the bottom of the top plate 7 and the top of the adjusting plate 82. When the staff lifts the adjusting plate 82, the upper positioning block 9 can be moved out of the upper positioning groove 13. This makes it convenient for the staff to take out the winding shaft 12 wound with the advertising paper 14 so as to replace the advertising paper 14.

[0029] The moving mechanism 16 includes a moving plate 161, a rectangular plate 162 and a hollow cylinder 163. The surface of the moving plate 161 is slidably connected to the inner wall of the fixed frame 15. The screw rod 20 threadedly penetrates the moving plate 161. The rectangular plate 162 is fixedly connected to the bottom of the moving plate 161. A rectangular groove is provided on the top of the advertising frame 1. The surface of the rectangular plate 162 contacts the inner wall of the rectangular groove. The hollow cylinder 163 is fixedly connected to the bottom of the rectangular plate 162. The surface of the hollow cylinder 163 contacts the inner wall of the advertising frame 1. When the screw rod 20 rotates with the cooperation of the bevel gear disk 21 and the bevel gear 63, the moving plate 161 drives the rectangular plate 162 to move. At this time, the hollow cylinder 163 moves to retract the unfolded advertising paper 14 so that the staff can replace the advertising paper 14. One end of the advertising paper 14 is placed inside the hollow cylinder 163 through the second slot 17. Thereafter, the staff can fix the position of one end of the advertising paper 14 through the cooperation of the auxiliary mechanism 18 and the extrusion frame 19.

[0030] The auxiliary mechanism 18 includes a connecting rod 181, a worm wheel 182 and a worm 183. The top of the connecting rod 181 is rotatably connected to the top of the inner wall of the cavity, and the bottom of the connecting rod 181 rotates and penetrates the hollow cylinder 163. The worm wheel 182 is fixedly sleeved on the surface of the connecting rod 181, and the worm 183 rotates and penetrates the hollow cylinder 163 and meshes with the worm wheel 182. One end of the worm 183 is fixedly connected to a short column, which rotates and penetrates the hollow cylinder 163, and a cross groove is provided on the surface. The extrusion frame 19 is fixedly connected to the bottom of the connecting rod 181. The staff can drive the hollow cylinder 163 to rotate by rotating the short column using a tool. At this time, the hollow cylinder 163 cooperates with the rectangular plate 162 and drives the extrusion frame 19 to rotate through the movable plate 161. At this time, the extrusion frame 19 and the hollow cylinder 163 can cooperate to clamp and squeeze the end of the advertising paper 14 placed inside the hollow cylinder 163.

[0031] The bottom of the hollow tube 163 is fixedly connected to the limiting block 22, and the bottom of the inner wall of the advertising frame 1 is provided with a limiting groove 23. The surface of the limiting block 22 contacts the inner wall of the limiting groove 23. The movement of the hollow tube 163 can be guided by the cooperation between the limiting block 22 and the limiting groove 23, thereby improving the stability of the moving mechanism 16 during movement.

[0032] Working principle: When replacing the advertising paper 14, the staff can first start the motor 61, and the bevel gear 63 cooperates with the bevel gear plate 21 to drive the screw 20 to rotate, and the screw 20 drives the moving plate 161 to move, and the rectangular plate 162 drives the hollow cylinder 163 to move to the position of the empty box 2, thereby one end of the advertising paper 14 can be retracted, and at the same time, the rotating shaft 62 drives the adjusting mechanism 8 to rotate through the top plate 7, and the winding shaft 12 rotates accordingly to rewind the advertising paper 14, and then the staff uses a tool to rotate the short column to drive the worm 183 to rotate, and the worm 183 drives the worm wheel 182 to rotate, and the connecting rod 181 drives the squeezing frame 19 to rotate to release the fixation of one end of the advertising paper 14, and finally the staff lifts the compression spring 83 upwards to release the fixation of the upper positioning block 9 on the top of the winding shaft 12, and thereby the staff can quickly remove the winding shaft 12 wound with the advertising paper 14 to replace the advertising paper 14;

[0033] When installing the advertising paper 14, the staff first preliminarily limits the position of the winding shaft 12 by the cooperation between the positioning groove 13 at the bottom of the winding shaft 12 and the lower positioning block 11, and then under the action of the elastic force of the compression spring 83, the upper positioning block 9 descends and cooperates with the upper positioning groove 13 to limit the positioning groove 13. Thereafter, the staff can pass one end of the advertising paper 14 through the first slot 3 and the second slot 17 to place one end of the advertising paper 14 inside the hollow tube 163. Then, the staff uses a tool to rotate the short column in the opposite direction to fix the position of one end of the advertising paper 14 through the cooperation of the extrusion frame 19 and the hollow tube 163. Finally, the staff starts the motor 61 to work in reverse, and the rotating shaft 62 drives the bevel gear 63 to rotate in the opposite direction. While the winding shaft 12 rotates in the opposite direction, the screw 20 rotates in the opposite direction and drives the hollow tube 163 to move to the side away from the empty box 2 through the movable plate 161 and the rectangular plate 162, so as to unfold the advertising paper 14, and the replacement operation of the advertising paper 14 can be completed.
