Flow of mechanical operation of the entire device:
1. 1. The feed belt 20 operates to feed the wallpaper waiting to be cut to the lower side of the cutting knife 27, and the front and rear sides where the wallpaper is cut are located above the two front and rear support plates 18, respectively. At this time, the first electromagnet 12 operates and repels the elevating block 15, thereby lowering the elevating block 15, thereby lowering the elevating plate 16, which causes the lower end of the cutting knife 27 to come into contact with the wallpaper, and the first electromagnet 12 operates. At that time, the drive motor 47 operates to rotate the drive shaft 46, thereby lowering the thread block 63 and the drive block 51, thereby lowering the push rod 49, thereby lowering the push block 50 and the slide block 45. As a result, the raising plate 41 and the drive gear 44 are lowered, and the lowering of the raising plate 41 lowers the raising rod 42, whereby the sandwich plate 17 is lowered, and when the sandwich plate 17 is lowered and comes into contact with the wallpaper, it continues to be lowered. As a result, the wallpaper is tightly sandwiched between the sandwich plate 17 and the support plate 18, and the return spring 40 is loosened.
2. When the raising plate 41 is lowered and the sandwich plate 17 and the support plate 18 tightly sandwich the wallpaper, the drive block 51 and the drive gear 44 are also lowered to the lowermost side, and in the process of lowering the drive block 51, the extrusion block 61 and the driven block 55 are lowered. When they come into contact with each other, the extrusion block 61 is moved upward, which pulls the fine string 66, compresses the extrusion spring 62, and at this time, the transmission of the fine string 66 moves the thread block 63 to the left. As a result, the thread block 63 and the drive shaft 46 are separated from each other, the position limiting spring 64 is compressed, and the drive block 51 is not lowered due to the separation between the thread block 63 and the drive shaft 46, whereby the raising plate 41 and the drive gear are separated. When the thread block 63 and the drive shaft 46 are separated from each other when the 44 cannot be lowered, the drive gear 44 is lowered and meshes with the rear end of the transmission gear 32. At this time, the rotation of the drive shaft 46 causes the drive gear 44 to rotate. The transmission gear 32 and the transmission shaft 34 are rotated, thereby rotating the reel 39, the torsion spring 33 is twisted, and the rotation of the reel 39 tightly winds the rope 26, thereby moving the slide block 28 to the left.
3. 3. When the slide block 28 moves to the left and moves the cutting knife 27 to the left, which begins to cut the wallpaper, the elastic spring 29 is pulled and the slide block 28 moves until it comes into contact with the slide plate 24, it slides. The block 28 continues to move to the left, which moves the slide plate 24 to the left and compresses the slide spring 22, which loosens the two first elastic cords 23 and the upper first elastic cord 23. Loosen, thereby returning the two compression springs 37 on the left side, thereby moving the push block 35 on the left side upwards, thereby moving the transmission gear 32 upwards, thereby separating the transmission gear 32 from the drive gear 44. At this time, the transmission between the drive mechanism 70 and the transmission mechanism 67 is cut off, the cut is completed, the drive motor 47 stops operating, the lower first elastic cord 23 loosens, and the second electric magnet 57 operates. By the action of attracting the position limiting plate 71, the position limiting plate 71 moves to the left, thereby loosening the second elastic cord 56, thereby loosening the two compression springs 37 on the right side, thereby loosening the right side. The push block 35 of the above is moved upward, whereby the push block 35 on the right side and the transmission gear 32 are brought into contact with each other.
4. As the transmission gear 32 rises, the position limiting block 59 rises, which pulls the chain 53, which lowers the driven plate 52, which lowers the driven block 55, at which time the extrusion spring 62 returns and pushes out. The block 61 is lowered, thereby loosening the cord 66, whereby the thread block 63 is reconnected to the drive shaft 46 by the thread, and the transmission gear 32 rises and separates from the drive gear 44, so that the torsion spring 33 is released. It returns, which causes the transmission shaft 34 to rotate in the reverse direction, which causes the reel 39 to rotate in the reverse direction, which loosens the rope 26 and returns the telescopic spring 29, which causes the slide block 28 to move to the right. When the cutting knife 27 is moved to the right and returned, and the slide block 28 is moved to the right and returned to come into contact with the position limiting plate 71, the slide block 28 is returned and the position limiting plate 71 is moved to the right. As a result, the position limiting plate 71 is separated from the second electric magnet 57, thereby pulling the second elastic cord 56 and loosening the lower first elastic cord 23. At this time, the slide spring 22 returns to release the slide plate 24. It moves to the right and returns, at which time the two first elastic cords 23 are pulled again, which lowers the spring rod 30, which causes the compression spring 37 to compress again, which lowers the push block 35, which lowers it. As a result, the transmission gear 32 is lowered and returned, whereby the chain 53 is loosened and the driven plate 52 is returned, whereby the driven block 55 is returned to its original position and when the elastic spring 29 is returned, it is disconnected from the slide block 28. The knife 27 moves and returns to its original position.
5. When the transmission mechanism 67 and the cutting mechanism 69 return, the drive motor 47 reverses, thereby reversing the drive shaft 46, thereby raising the thread block 63, thereby raising the raising plate 41, the push rod 49, and the push rod 49. The drive gear 44 is raised, and when the raising plate 41 is raised, the raising rod 42 is raised, which raises the sandwich plate 17, which loosens the wallpaper, the return spring 40 is compressed again, and the driving gear 44 moves upward. In the process of moving and returning, the transmission gear 32 is lowered and meshes with the drive gear 44, the drive shaft 46 is inverted and the drive gear 44 is inverted, so that the power of the drive gear 44 is transmitted between the transmission gear 32 and the transmission shaft 34. As a result, when the reel 39 still rotates to loosen the rope 26 and the drive gear 44 moves upward and returns, the drive motor 47 stops operating, the first electromagnet 12 does not operate, and the elevating spring 14 returns. Then, the elevating block 15 is raised, thereby raising the elevating plate 16, and at this time, the return of the device is completed, and the feed belt 20 operates to feed the cut wallpaper.

The above is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited to this. Changes and replacements that come to mind through all creative labor are covered by the scope of the invention. Therefore, the scope of protection of the present invention is based on the scope of protection in which the request for rights is limited.

Flow of mechanical operation of the entire device:
1. 1. The feed belt 20 operates to feed the wallpaper waiting to be cut to the lower side of the cutting knife 27, and the front and rear sides where the wallpaper is cut are located above the two front and rear support plates 18, respectively. At this time, the first electromagnet 12 operates and repels the elevating block 15, thereby lowering the elevating block 15, thereby lowering the elevating plate 16, which causes the lower end of the cutting knife 27 to come into contact with the wallpaper, and the first electromagnet 12 operates. At that time, the drive motor 47 operates to rotate the drive shaft 46, thereby lowering the thread block 63 and the drive block 51, thereby lowering the push rod 49, thereby lowering the push block 50 and the slide block 45. As a result, the raising plate 41 and the drive gear 44 are lowered, and the lowering of the raising plate 41 lowers the raising rod 42, whereby the sandwich plate 17 is lowered, and when the sandwich plate 17 is lowered and comes into contact with the wallpaper, it continues to be lowered. As a result, the wallpaper is tightly sandwiched between the sandwich plate 17 and the support plate 18, and the return spring 40 is loosened.
2. When the raising plate 41 is lowered and the sandwich plate 17 and the support plate 18 tightly sandwich the wallpaper, the drive block 51 and the drive gear 44 are also lowered to the lowermost side, and in the process of lowering the drive block 51, the extrusion block 61 and the driven block 55 are lowered. When they come into contact with each other, the extrusion block 61 is moved upward, which pulls the fine string 66, compresses the extrusion spring 62, and at this time, the transmission of the fine string 66 moves the thread block 63 to the left. As a result, the thread block 63 and the drive shaft 46 are separated from each other, the position limiting spring 64 is compressed, and the drive block 51 is not lowered due to the separation between the thread block 63 and the drive shaft 46, whereby the raising plate 41 and the drive gear are separated. When the thread block 63 and the drive shaft 46 are separated from each other when the 44 cannot be lowered, the drive gear 44 is lowered and meshes with the rear end of the transmission gear 32. At this time, the rotation of the drive shaft 46 causes the drive gear 44 to rotate. The transmission gear 32 and the transmission shaft 34 are rotated, thereby rotating the reel 39, the torsion spring 33 is twisted, and the rotation of the reel 39 tightly winds the rope 26, thereby moving the slide block 28 to the left.
3. 3. When the slide block 28 moves to the left and moves the cutting knife 27 to the left, which begins to cut the wallpaper, the elastic spring 29 is pulled and the slide block 28 moves until it comes into contact with the slide plate 24, it slides. The block 28 continues to move to the left, which moves the slide plate 24 to the left and compresses the slide spring 22, which loosens the two first elastic cords 23 and the upper first elastic cord 23. Loosen, thereby returning the two compression springs 37 on the left side, thereby moving the push block 35 on the left side upwards, thereby moving the transmission gear 32 upwards, thereby separating the transmission gear 32 from the drive gear 44. At this time, the transmission between the drive mechanism 70 and the transmission mechanism 67 is cut off, the cut is completed, the drive motor 47 stops operating, the lower first elastic cord 23 loosens, and the second electric magnet 57 operates. By the action of attracting the position limiting plate 71, the position limiting plate 71 moves to the left, thereby loosening the second elastic cord 56, thereby loosening the two compression springs 37 on the right side, thereby loosening the right side. The push block 35 of the above is moved upward, whereby the push block 35 on the right side and the transmission gear 32 are brought into contact with each other.
4. As the transmission gear 32 rises, the position limiting block 59 rises, which pulls the chain 53, which lowers the driven plate 52, which lowers the driven block 55, at which time the extrusion spring 62 returns and pushes out. The block 61 is lowered, thereby loosening the cord 66, whereby the thread block 63 is reconnected to the drive shaft 46 by the thread, and the transmission gear 32 rises and separates from the drive gear 44, so that the torsion spring 33 is released. It returns, which causes the transmission shaft 34 to rotate in the reverse direction, which causes the reel 39 to rotate in the reverse direction, which loosens the rope 26 and returns the telescopic spring 29, which causes the slide block 28 to move to the right. When the cutting knife 27 is moved to the right and returned, and the slide block 28 is moved to the right and returned to come into contact with the position limiting plate 71, the slide block 28 is returned and the position limiting plate 71 is moved to the right. As a result, the position limiting plate 71 is separated from the second electric magnet 57, thereby pulling the second elastic cord 56 and loosening the lower first elastic cord 23. At this time, the slide spring 22 returns to release the slide plate 24. It moves to the right and returns, at which time the two first elastic cords 23 are pulled again, which lowers the spring rod 30, which causes the compression spring 37 to compress again, which lowers the push block 35, which lowers it. As a result, the transmission gear 32 is lowered and returned, whereby the chain 53 is loosened and the driven plate 52 is returned, whereby the driven block 55 is returned to its original position and when the elastic spring 29 is returned, it is disconnected from the slide block 28. The knife 27 moves and returns to its original position.
5. When the transmission mechanism 67 and the cutting mechanism 69 return, the drive motor 47 reverses, thereby reversing the drive shaft 46, thereby raising the thread block 63, thereby raising the raising plate 41, the push rod 49, and the push rod 49. The drive gear 44 is raised, and when the raising plate 41 is raised, the raising rod 42 is raised, which raises the sandwich plate 17, which loosens the wallpaper, the return spring 40 is compressed again, and the driving gear 44 moves upward. In the process of moving and returning, the transmission gear 32 is lowered and meshes with the drive gear 44, the drive shaft 46 is inverted and the drive gear 44 is inverted, so that the power of the drive gear 44 is transmitted between the transmission gear 32 and the transmission shaft 34. As a result, when the reel 39 still rotates to loosen the rope 26 and the drive gear 44 moves upward and returns, the drive motor 47 stops operating, the first electromagnet 12 does not operate, and the elevating spring 14 returns. Then, the elevating block 15 is raised, thereby raising the elevating plate 16, and at this time, the return of the device is completed, and the feed belt 20 operates to feed the cut wallpaper.

Changes and replacements that come to mind through all creative labor are covered by the scope of the invention. Therefore, the scope of protection of the present invention is based on the scope of protection in which the request for rights is limited.
