Improving the unloading efficiency of this winding device helps to improve production efficiency.

[0033] A rotating rod 14 is fixed to the middle of the surface of the rotating roller 5 near the fixed plate 3. The rotating rod 14 is horizontal and passes through both sides of the middle of the fixed plate 3. The rotating rod 14 helps to rotate the rotating roller 5, making it easy to use. The outer ring surface of the rotating rod 14 is rotatably connected to the middle of the fixed plate 3 through a bearing. A rotating motor 4 is installed in the middle of the surface of the fixed plate 3 away from the rotating roller 5, corresponding to the rotating rod 14. The fixed plate 3 can fix and limit the rotating motor 4. The output shaft of the rotating motor 4 faces the rotating rod 14 and is fixedly connected to the opposite end of the rotating rod 14. A matching retention hole 13 is opened in the middle of the upper end of the fixed plate 3 corresponding to the output rod of the hydraulic cylinder 11. The rotating motor 4 helps to drive the rotating rod 14 to rotate.

[0034] Several locking blocks 8 are fixed at intervals along the circumferential direction on the outer side of the middle part of the outer ring surface of the rotating roller 5. Several matching slots 9 are opened at intervals along the circumferential direction on the inner ring surface of the wallpaper roll 7 corresponding to the locking blocks 8. The locking blocks 8 and slots 9 facilitate the limiting of the rotating roller 5 and the wallpaper roll 7. The slots 9 all penetrate through the two end surfaces of the corresponding positions on the wallpaper roll 7. The slots 9 on the wallpaper roll 7 are slidably connected with the outer side of the corresponding locking block 8 in the horizontal direction. The slots 9 on the wallpaper roll 7 can limit the locking blocks 8.

[0035] A fixing ring 6 is fixed to the middle of the surface of the fixing plate 3 near the rotating roller 5, located on the outer side of the rotating roller 5. The end of the outer ring surface of the rotating roller 5 near the fixing plate 3 is rotatably connected to the inner ring surface of the fixing ring 6 through a bearing. The fixing ring 6 helps to limit the rotation of the rotating roller 5, making it easy to rotate the rotating roller 5 stably. The fixing plate 3 is in a vertical state, and a horizontal mounting plate 1 is fixed to the lower surface of the fixing plate 3. Bolts 2 are threaded into the four corners of the mounting plate 1 in the vertical direction. The bolts 2 can install and limit the mounting plate 1, making it easy to use the mounting plate 1 stably.

[0036] The working principle of this utility model is as follows: During use, the lower surface of the mounting plate 1 is aligned with the position on the wallpaper printing machine where the wallpaper needs to be installed, so that the lower surface of the mounting plate 1 and the corresponding position on the wallpaper printing machine are in a matching and fitting state. Furthermore, the mounting plate 1 is installed with the corresponding position on the wallpaper printing machine by bolts 2. The bolts 2 can fix and limit the mounting plate 1, which facilitates the stable use of the mounting plate 1. The mounting plate 1 can support and limit the fixing plate 3 and the various components assembled on the fixing plate 3, which helps to stabilize the use of the fixing plate 3 and the various components assembled on the fixing plate 3.

[0037] When the printed wallpaper needs to be rolled up, the printed wallpaper is wound around the retaining ring 10 on the outside of the wallpaper roll 7. Then, the rotating motor 4 on the fixing plate 3 is opened. The fixing plate 3 can fix and limit the rotating motor 4, facilitating stable use of the rotating motor 4. With the rotating motor 4 open, its output shaft can drive the rotating rod 14 to rotate. The rotating rod 14, when rotating, can drive the rotating roller 5 to rotate. The rotating roller 5 rotates along the inner side of the fixing ring 6. The fixing plate 3 can then control the rotating roller 5 through the fixing ring 6. The limit switch helps to stably rotate the rotating roller 5. When the rotating roller 5 rotates, it can drive the wallpaper take-up drum 7 to rotate through the locking block 8 and the locking groove 9. When the wallpaper take-up drum 7 rotates, it can roll up the wallpaper after printing. When the wallpaper take-up drum 7 rotates, it can drive the retaining ring 10 to rotate, so that the edge of the retaining ring 10 near the fixed plate 3 rotates along the inner side of the U-shaped frame 12. The U-shaped frame 12 can limit the wallpaper take-up drum 7 through the retaining ring 10, which can prevent the wallpaper take-up drum 7 from displacement and make it easy to ensure that the wallpaper take-up drum 7 stably rolls up the wallpaper after printing.

[0038] After the wallpaper is rolled up by the wallpaper take-up drum 7, the rotating motor 4 is turned off, causing the wallpaper take-up drum 7 to stop rotating. Then, the hydraulic cylinder 11 on the fixing plate 3 is opened. The fixing plate 3 can fix and limit the hydraulic cylinder 11, which helps to stabilize the use of the hydraulic cylinder 11. When the hydraulic cylinder 11 is open, the output rod of the hydraulic cylinder 11 can drive the U-shaped frame 12 to move away from the fixing plate 3. When the U-shaped frame 12 moves, it can drive the wallpaper take-up drum 7 to move away from the fixing plate 3 through the retaining ring 10. This allows the wallpaper take-up drum 7 to move away from the fixing plate 3 along the outside of the rotating roller 5 and the retaining block 8 through the slot 9. When the wallpaper take-up drum 7 moves, it can drive the wallpaper rolled on the outside to move. After the wallpaper take-up drum 7 is moved to the point of separation from the rotating roller 5, it moves downward under its own weight, so that the retaining ring 10 separates from the U-shaped frame 12, so as to unload the wallpaper take-up drum 7 and the wallpaper rolled on the outside.

[0039] The top of the retaining ring 10 on the unrolled wallpaper roll 7 is aligned with the inside of the U-shaped frame 12, so that the inside of the wallpaper roll 7 and the slot 9 correspond with the rotating roller 5 and the locking block 8. The hydraulic cylinder 11 drives the U-shaped frame 12 to move toward the fixing plate 3. The U-shaped frame 12 can move and reset the wallpaper roll 7 and the slot 9 along the outside of the rotating roller 5 and the locking block 8 toward the fixing plate 3 through the retaining ring 10, so as to assemble the wallpaper roll 7 and the rotating roller 5. After the wallpaper roll 7 is assembled, it helps the wallpaper roll 7 to roll up the wallpaper after subsequent printing and processing.

[0040] During use, when unloading the wallpaper after it has been rolled up in this winding device, it is convenient to unload the wallpaper after it has been rolled up. The unloading process of the wallpaper after it has been rolled up is convenient and helps to save manpower during the unloading process, so as to reduce the labor intensity of the workers. Improving the unloading efficiency of this winding device helps to improve production efficiency.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
