The wallpaper can pass from below the first guide roller 28 into the tension roller 24, and then pass under the second guide roller 29. The wallpaper can push the tension roller 24 to move downward. The downward movement of the tension roller 24 can drive the movable block 23 to move. The downward movement of the movable block 23 can compress the spring 27 to deform it. Through the elasticity of the spring 27, the tension roller 24 can be pushed upward to tension the wallpaper, thereby preventing the wallpaper from loosening and improving the stability of wallpaper pasting. A fixing frame 41 is fixedly connected to one side of the top of the movable seat 1. A first cylinder 42 is fixedly connected to the top of the fixing frame 41. The bottom of the first cylinder 42 A cutting blade 43 is fixedly connected to the frame 41. A slit 44 is opened at the bottom of the frame 41. A third guide roller 45 is provided on one side of the frame 41 and is fixedly connected to the movable seat 1. Activation of the first cylinder 42 pushes the cutting blade 43 to move vertically. The movement of the cutting blade 43 cuts the wallpaper, eliminating the need for manual cutting and ensuring that the wallpaper cut 44 does not tilt. The third guide roller 45 supports the wallpaper, further preventing tilting. Guide rods 71 ​​are fixedly connected to both sides of the top of the cutting blade 43. The guide rods 71 ​​pass through the frame 41 and are slidably connected to it, guiding the movement of the cutting blade 43. To improve the vertical stability of the cutting blade 43 and prevent it from tilting, a second cylinder 51 is fixedly connected to both sides of the top of the moving base 1. A connecting plate 52 is fixedly connected to the top of the second cylinder 51, and a fixed roller 53 is fixedly connected to one side of the connecting plate 52. When the second cylinder 51 is activated, it can push the connecting plate 52 to move vertically, which in turn can drive the fixed roller 53 to move vertically, so that the fixed roller 53 can squeeze the wallpaper and paste it.

[0026] Please see Figure 1 , Figure 2 , Figure 5 as well as Figure 6The replaceable components include slots 31 on both sides of the wallpaper roller 11, grooves 32 on both sides of the top of the movable base 1, a slider 33 in the groove 32, a movable plate 34 fixedly connected to the top of the slider 33, a rotating shaft 35 connected to one side of the movable plate 34, a bidirectional screw 36 connected to the slider 33, and a motor 37 fixedly connected to one end of the bidirectional screw 36. The slider 33 is slidably connected to the groove 32, the bidirectional screw 36 is screwed to the movable block 23, the bidirectional screw 36 is rotatably connected to the movable base 1, the rotating shaft 35 is rotatably connected to the movable plate 34, and the motor 37 can drive the bidirectional screw 36 to rotate when started. The rotation of the bidirectional screw 36 causes the two sliders 33 to move in opposite directions, which in turn causes the two moving plates 34 to move in opposite directions. The moving plates 34 can drive the rotating shaft 35 to move. The rotating shaft 35 can be inserted into or disengaged from the slot 31, which facilitates the replacement of the wallpaper roller 11 and can indirectly speed up the wallpapering process. An anti-rotation plate 61 is fixedly connected to the outside of the rotating shaft 35. An anti-rotation opening 62 is provided on the inner wall of the slot 31. The anti-rotation plate 61 is inserted into the anti-rotation opening 62, which allows the rotating shaft 35 to rotate when the wallpaper roller 11 rotates, making the rotation of the wallpaper roller 11 smoother.

[0027] Working principle: During operation, the motor 37 is started, which drives the bidirectional screw 36 to rotate.

Then, the slots 31 at both ends of the wallpaper roller 11 are aligned with the rotating shaft 35, and the anti-rotation plate 61 is aligned with the anti-rotation opening 62. As the rotating shaft 35 moves, the rotating shaft 35 and the anti-rotation plate 61 are inserted into the slots 31 and the anti-rotation opening 62 respectively, completing the installation of the wallpaper roller 11. Then, the wallpaper passes from below the first guide roller 28 into the tension roller 24, then passes under the second guide roller 29, and then passes through the fixing frame 41 to the side of the fixing roller 53. The wallpaper can push the tension roller 24 downward. The tension roller 24 moves downward, which drives the moving block 23 to move. The moving block 23 moves downward, which compresses the spring 27 and causes it to deform. Through the elasticity of the spring 27, the tension roller 24 can be pushed upward to tension the wallpaper, thereby preventing the wallpaper from loosening. Then the wallpaper can be pasted onto the wall. The second cylinder 51 is activated, which drives the connecting plate 52 to move downward, which in turn drives the fixed roller 53 to move downward, so that the wallpaper can be pasted. After pasting is completed, the first cylinder 42 is activated to push the cutting blade 43 downward, so that the wallpaper can be cut. The above is the working process of the whole device. All contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
