Description

Technical Field

[0001] This application relates to the field of wallpapering tools, and in particular to an auxiliary device and construction method for wallpapering. Background Technology

[0002] Wallpaper, as an interior decoration material, has become a favorite in the furniture industry due to its diverse colors, rich patterns, safety, and environmental friendliness. Currently, wallpaper is pasted manually by workers. The pasting process includes wall preparation, wallpaper cutting, adhesive application, wallpaper installation, and edge cleaning. The process is lengthy and slow. If workers are not skilled, they may make mistakes that result in uneven wallpaper pasting, leading to waste of wallpaper, work delays, and even affecting the aesthetics of the wall.

[0003] Based on this, the wallpaper is placed inside a casing, which is equipped with an adhesive applicator for applying glue to the inside of the wallpaper. When pasting the wallpaper, one end of the wallpaper is first pulled out from the casing and pasted to the bottom of the wall. Then, the casing is moved from top to bottom by an electric push rod, which can achieve the function of wallpapering. This reduces the steps of applying glue and reduces the possibility of uneven wallpaper pasting, thus improving construction efficiency.

[0004] However, before using the shell to cover the wallpaper, the staff needs to pull out a section of wallpaper and apply glue to it to stick it to the junction of the wall and the ceiling. Since the staff needs to climb to a high place to stick the pulled-out wallpaper, it is inconvenient and increases the safety hazard. Summary of the Invention

[0005] To facilitate wallpapering on walls, this application provides a wallpapering auxiliary device and construction method.

[0006] Firstly, the wallpaper mounting auxiliary device provided in this application adopts the following technical solution:

[0007] A wallpaper mounting auxiliary device includes a housing, a lifting mechanism, a smoothing mechanism, and an adhesive applicator. The housing has a storage cavity for mounting wallpaper and an opening for wallpaper to pass through. The lifting mechanism is used to lift the housing along the height direction. The smoothing mechanism is used to smooth the wallpaper pasted on the wall. The adhesive applicator is used to apply adhesive to the inner side of the wallpaper.

[0008] The adhesive application mechanism includes a rotating roller and multiple sets of first and second adhesive extrusion assemblies mounted on the rotating roller. The rotating roller is rotatably mounted inside the receiving cavity, and the outer wall of the rotating roller abuts against the inner wall of the opening. All the first adhesive extrusion assemblies are spaced apart along the outer peripheral wall of the rotating roller, and the first adhesive extrusion assemblies are located between two adjacent sets of second adhesive extrusion assemblies. The adhesive in the first adhesive extrusion assembly contains magnetic powder. The leveling mechanism is mounted on the outer wall of the housing near the opening, and the leveling mechanism is located on the upper end face of the housing. The leveling mechanism is provided with a magnetic suction element, which is used to cooperate with the magnetic powder in the adhesive.

[0009] By adopting the above technical solution, when wallpapering the wall, the first extrusion assembly is turned on, and then the wallpaper is rotated out between the rotating roller and the inner wall of the opening. At this time, multiple first extrusion assemblies can evenly apply the glue with magnetic powder to the inner side of the wallpaper, and the magnetic suction of the scraping mechanism is turned on, so that the wallpaper with magnetic powder can be attracted by the magnetic suction; and the first extrusion assembly is turned off and the second extrusion assembly is turned on.

[0010] Then, the lifting mechanism can move the shell to the top, and the scraping mechanism located on the upper surface of the shell can abut against the junction of the wall and the top of the wall, that is, it can move the end of the wallpaper to the top of the wall and start the bonding from the junction of the wall and the top of the wall; reducing the need for workers to first pull out part of the wallpaper and climb to the top of the wall through scaffolding to bond it to the wall, thus improving work efficiency.

[0011] Next, the lifting mechanism moves the housing from the top of the wall to the bottom. During this process, as the wallpaper is pulled out from the opening of the housing, the second adhesive applicator applies adhesive to the wallpaper, ensuring it adheres to the wall. Simultaneously, the smoothing mechanism smooths the wallpaper and removes air bubbles between the wallpaper and the wall, improving the wallpaper's adhesion. This device can perform the processes of applying adhesive, pasting, and removing air bubbles from the wallpaper, significantly improving the efficiency of wallpapering.

[0012] Optionally, the first extrusion assembly includes an extrusion block and an air bladder. The rotating roller has a first extrusion groove, and the extrusion block is movably installed in the first extrusion groove. The air bladder is disposed between the extrusion block and the first extrusion groove. The extrusion block has an extrusion hole communicating with the air bladder, and the air bladder is connected to an external glue application device. The first extrusion block is provided with a first guide surface for guiding the first extrusion block into the first extrusion groove. The rotating roller has a second extrusion groove, and the second extrusion assembly is disposed in the second extrusion groove.

[0013] By adopting the above technical solution, when the wallpaper is pulled out from between the rotating roller and the inner wall of the opening, the rotating roller can rotate. At this time, during the rotation of the rotating roller, the first guide surface can abut against the shell and cause the extrusion block to move into the first extrusion groove. Since the airbag is subjected to the first extrusion groove, the glue in the airbag can be squeezed out from the extrusion hole and applied to the back side of the wallpaper, thereby completing the glue application work.

[0014] Optionally, a first spring is provided inside the airbag, and the elastic force of the first spring drives the extrusion block to move toward the side away from the first extrusion groove.

[0015] By adopting the above technical solution, and by setting the first spring, the airbag can be deformed by the squeezing block, which can help the airbag to return to its original position, so that the squeezing block can apply glue to the inner wall of the wallpaper next time.

[0016] Optionally, the outer wall of the rotating roller is rotatably mounted with multiple baffles. When the baffles cover the first extrusion groove, the rotating roller is in a first state; when the baffles cover the second extrusion groove, the rotating roller is in a second state; the rotating roller is equipped with a conversion component for switching the first state and the second state of the rotating roller.

[0017] By adopting the above technical solution, the first and second states of the rotating roller can be switched by rotating the baffle. When the rotating roller is in the first state, the second extrusion component is exposed in the second extrusion groove, so that the second extrusion component applies the glue without magnetic powder to the inner side of the wallpaper to complete the wall coating work. When it is necessary to paste the end of the wallpaper to the top of the wall, the rotating roller is switched to the second state, and then the extrusion block is exposed to the outside and the wallpaper is coated with glue with magnetic powder, so that the end of the wallpaper can be magnetically attracted to the upper surface of the housing and moved.

[0018] Optionally, the conversion assembly includes a rotating disk, a positioning rod, and a positioning plate; the rotating disk is rotatably mounted on the end of the rotating roller, all baffles are connected to the rotating disk, and the positioning rod is slidably mounted on the rotating disk; the positioning plate is fixed to the end of the rotating roller and located on the side of the rotating disk away from the rotating roller; the positioning groove has a conversion groove, and the positioning ring passes through the conversion groove and is exposed to the outside.

[0019] The conversion slot has two positioning slots. A second spring is provided between the positioning rod and the rotating disk. The elastic force of the second spring drives the positioning rod to be normally inserted into the positioning slot. When the positioning rod is inserted into one of the positioning slots, the rotating roller is in a first state. When the positioning rod is inserted into the other positioning slot, the rotating roller is in a second state.

[0020] By adopting the above technical solution, when changing the first state / second state of the rotating roller, the positioning rod is slid to cancel the insertion of the positioning rod into the positioning groove; thereby, the positioning rod can move in the conversion groove to make the rotating disk rotate, and then the baffle can rotate on the outer wall of the rotating roller, so that the baffle covers the surface of the first extrusion groove / second extrusion groove; the positioning rod is inserted into the positioning groove to complete the fixation of the baffle position.

[0021] Optionally, the smoothing mechanism includes a sponge strip and a pressing assembly, the pressing assembly being movably mounted on the housing, the housing being provided with a third spring for driving the pressing assembly to move toward a side away from the housing, and the sponge strip being provided on the pressing assembly for contacting the wallpaper.

[0022] By adopting the above technical solution, and by setting up a clamping component, when the housing moves along the height of the wall, the clamping component, under the elastic force of the third spring, presses the wallpaper firmly against the wall. During the movement of the clamping component, air between the wallpaper and the wall is scraped out, thereby improving the adhesion of the wallpaper to the wall. Furthermore, when the wall panel surface has protrusions, the clamping component moves away from the wall panel, reducing the possibility of directly rolling over the protrusions and damaging the wallpaper. And when the clamping component passes over a protrusion, it re-presses against the wallpaper under the elastic force of the third spring, continuously scraping out air and smoothing the wallpaper.

[0023] Optionally, the clamping assembly includes at least two sets of clamping members, all of which are spaced apart along the height direction of the housing; each clamping member includes multiple scrapers, all of which are spaced apart along the extension direction of the rotating roller, with the scrapers of adjacent sets of clamping members spaced apart; the housing has a clamping groove, the scrapers are movably installed in the clamping groove, and the third spring is installed in the clamping groove; the sponge strip has an installation groove, and all scrapers are installed in the clamping groove.

[0024] By adopting the above technical solution, by setting the clamping assembly into two sets of clamping parts and setting the clamping parts in a staggered manner, the wall leveling work can be further improved. When encountering a wall protrusion, the scraper that is in contact with the protrusion can retract into the clamping groove, while the other scrapers can still level the wall panel, further improving the leveling effect of the wall panel.

[0025] Optionally, the bottom of the storage cavity and the bottom of the opening are both in communication with the outside. The housing is equipped with a moving component, which is used to move the rotating roller into the storage cavity and abut against the inner wall of the storage cavity. When the lifting mechanism drives the housing to the bottom, the inner wall of the opening abuts against the ground.

[0026] By adopting the above technical solution, the storage cavity and the bottom of the opening are connected to the outside, and the bottom of the opening can abut against the floor, allowing the wallpaper to be pasted to the bottom of the wall, thus improving the wallpapering effect. This allows the wallpaper to be partially pasted to the floor, and during subsequent floor tiling work, the wallpaper can be partially sandwiched between the floor tiles and the floor, reducing the occurrence of wallpaper curling at the bottom and further improving the wallpapering effect.

[0027] Optionally, a cutting blade is installed on the inner wall of the storage cavity, and a first cylinder for driving the cutting blade to cut the wallpaper is installed in the housing.

[0028] By adopting the above technical solution and setting a cutting blade, the wallpaper can be cut after the wallpapering work is completed, thereby improving work efficiency.

[0029] Secondly, the construction method of the wallpaper mounting auxiliary device provided in this application adopts the following technical solution.

[0030] S1 installs the wallpaper into the storage cavity, activates the first extrusion assembly, and pulls the end of the wallpaper out from between the rotating roller and the inner wall of the opening;

[0031] S2 opens the magnetic suction component to fix the wallpaper with magnetic powder to the side of the housing near the opening, closes the first extrusion assembly, and opens the second extrusion assembly;

[0032] S3 activates the lifting mechanism to raise the housing to the top, where it abuts against the wall;

[0033] S4 restarts the lifting assembly to lower the housing, the wallpaper is pulled out of the storage cavity and pasted onto the wall, and the smoothing mechanism smooths the wallpaper.

[0034] The S6 cuts the wallpaper and completes the wallpapering process.

[0035] By employing the above-described technical solution, the lifting mechanism moves the housing from the top to the bottom of the wall, allowing the wallpaper inside the storage cavity to be pasted onto the wall. Furthermore, the smoothing mechanism smooths the wallpaper and removes air bubbles between the wallpaper and the wall, improving the wallpaper's adhesion. This device enables the application of adhesive, pasting, and removal of air bubbles from the wallpaper, significantly improving the efficiency of wallpapering.

[0036] In summary, this application includes at least one of the following beneficial technical effects:

[0037] 1. By applying adhesive containing magnetic powder to the wallpaper and attaching it to the open side of the casing using magnetic attachments, the lifting mechanism can move the casing to the top. The smoothing mechanism on the upper surface of the casing can then engage with the junction of the wall and ceiling, allowing the wallpaper to be moved to the top of the wall for bonding. This reduces the need for workers to first remove parts of the wallpaper and climb scaffolding to the top of the wall to bond it, thus improving work efficiency.

[0038] 2. By setting the clamping assembly to two sets of clamping parts and staggering the clamping parts, the wall leveling work can be further improved. When encountering a wall protrusion, the scraper that is in contact with the protrusion can retract into the clamping groove, while the other scrapers can still level the wall panel, further improving the leveling effect of the wall panel.

[0048] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0049] Example 1:

[0050] This application discloses a wallpaper mounting auxiliary device.

[0051] Reference Figure 1 A wallpaper mounting auxiliary device includes a housing 1, a lifting mechanism 2, a scraping mechanism 3, and an adhesive applicator 4. The lifting mechanism 2 is used to move the housing 1 along the height direction, the scraping mechanism 3 is used to scrape the wallpaper on the wall panel to remove air, and the adhesive applicator 4 is used to apply adhesive to the inner side of the wallpaper.

[0052] The lifting mechanism 2 includes a support base 22 and a linear module 21. The linear module 21 is mounted on the support base 22, and the housing 1 is mounted on the linear module 21. The linear module 21 is used to drive the housing 1 to move up and down. The housing 1 has a storage cavity 11 inside, and an opening 12 communicating with the storage cavity 11 is opened on the outer wall of the housing 1. A take-up roller 13 is installed in the storage cavity 11, and wallpaper is installed on the take-up roller 13. By rotating the take-up roller 13, the wallpaper can be passed through the opening 12 and pasted to the wall.

[0053] Reference Figure 2 and Figure 3The adhesive application mechanism 4 includes a rotating roller 41, a plurality of first extrusion components 42 and a plurality of second extrusion components 43. All the first extrusion components 42 are spaced apart along the outer peripheral wall of the rotating roller 41, and the second extrusion components 43 are disposed between two adjacent first extrusion components 42. The first extrusion components 42 and the second extrusion components 43 are both used to apply adhesive to the inner sidewall of the wallpaper. The adhesive in the first extrusion component 42 contains magnetic powder.

[0054] Reference Figure 4 The first extrusion assembly 42 includes an extrusion block 421, a first spring 422, and an airbag 423; a first extrusion groove 44 is formed on the outer surface of the rotating roller 41, and the extension direction of the first extrusion groove 44 is in the same direction as the extension direction of the rotating roller 41; the extrusion block 421 is movably installed in the first extrusion groove 44, and a first guide surface 424 is provided on the side of the extrusion block 421 away from the first extrusion groove 44, and the first guide surface 424 is used to guide the extrusion block 421 into the first extrusion groove 44;

[0055] An airbag 423 is installed between the extrusion block 421 and the inner wall of the first pressure groove. The extrusion block 421 has an extrusion hole 46, which communicates with the airbag 423. The housing 1 is equipped with a glue-applying device for adding glue into the airbag 423, and a one-way valve is provided between the glue-applying device and the airbag 423. A first spring 422 is installed inside the airbag 423, and the elastic force of the first spring 422 drives the extrusion block 421 to move away from the first extrusion groove 44.

[0056] The rotating roller 41 has a second extrusion groove 45, and the second extrusion assembly 43 is installed in the second extrusion groove 45. Since the structure of the second extrusion assembly 43 is the same as that of the first extrusion assembly 42, it will not be described in detail here.

[0057] Reference Figure 4 A baffle 47 is rotatably mounted on the outer wall of the rotating roller 41. The baffle 47 is used to cover the surface of the first extrusion groove 44 / or the second extrusion groove 45. When the baffle 47 covers the surface of the first extrusion groove 44, the rotating roller 41 is in a first state, that is, the second extrusion component 43 is exposed at the boundary of the second extrusion groove 45 to coat the inner wall of the wallpaper with adhesive without magnetic powder. When the baffle 47 covers the surface of the second extrusion groove 45, the rotating roller 41 is in a second state, that is, the first extrusion component 42 is exposed at the first extrusion groove 44 to coat the inner wall of the wallpaper with adhesive containing magnetic powder. The rotating roller 41 is also provided with a switching component 5 for switching between the first state and the second state of the rotating roller 41.

[0058] Reference Figure 5The conversion component 5 includes a rotating disk 51, a positioning rod 52 and a positioning disk 53. The positioning disk 53 is fixed to the end of the rotating roller 41. The positioning disk 53 has a conversion groove 54. The conversion groove 54 is arc-shaped, and the two ends of the conversion groove 54 are respectively located below the adjacent first extrusion groove 44 and second extrusion groove 45 at the two adjacent ends. The two ends of the conversion groove 54 are provided with positioning grooves 55.

[0059] The rotating disk 51 is rotatably mounted between the positioning disk 53 and the rotating roller 41. The ends of all the baffles 47 extend and are connected to the rotating disk 51, so that by rotating the rotating disk 51, the baffles 47 can cover the surface of the first extrusion groove 44 / second extrusion groove 45. The rotating disk 51 has a moving groove 56, the extension direction of the moving groove 56 is intersecting the extension direction of the rotating groove. The positioning rod 52 is slidably installed in the moving groove 56, and the end of the positioning rod 52 away from the rotating disk 51 passes through the conversion groove 54 and is exposed to the outside. By moving the position of the positioning rod 52 in the conversion groove 54, the position of the baffle 47 on the surface of the rotating roller 41 can be changed. A second spring 57 is provided between the positioning rod 52 and the inner wall of the moving groove 56. The elastic force of the second spring 57 drives the positioning rod 52 to be inserted into the positioning groove 55.

[0060] By changing the position of the positioning rod 52 in the conversion groove 54, the position of the positioning rod 52 can be changed. When the sliding positioning rod 52 is inserted into one of the positioning grooves 55 in the moving groove 56, the baffle 47 covers the surface of the second extrusion groove 45. At this time, the first extrusion groove 44 is exposed to the outside. The rotating roller 41 is in the second state. During the process of the wallpaper being pulled between the rotating roller 41 and the inner wall of the opening 12, the rotating roller 41 rotates, causing the extrusion block 421 to extrude the airbag 423 and squeeze the glue containing magnetic powder in the airbag 423 out from the first extrusion hole and apply it to the inner wall of the wallpaper so as to move it to the top of the wall.

[0061] Then, the positioning rod 52 is moved into another positioning groove 55, the baffle 47 covers the surface of the first extrusion groove 44, and the second extrusion assembly 43 is exposed to the outside, that is, the rotating roller 41 is in the first state. Then, during the descent of the lifting assembly, the housing 1 pulls the wallpaper out of the storage cavity 11, and the rotating roller 41 rotates, continuously applying glue to the inner wall of the wallpaper to facilitate the wallpaper being pasted onto the wall. By switching the rotating roller 41 between the first and second states by the switching assembly 5, the application of glue containing magnetic powder can be reduced, avoiding waste.

[0062] Refer to 1 and Figure 6The leveling component is located on the upper end face of the housing 1 near the opening 12. The leveling structure includes a sponge strip 31 and a pressing component 32. The pressing component 32 includes at least two sets of pressing members 33. In this embodiment, the pressing members 33 are set in two sets, and the two sets of pressing members 33 are spaced apart along the height direction of the housing 1. The pressing member 33 includes multiple scrapers 34. The housing 1 has a pressing groove 14. The extension direction of the pressing groove 14 is the same as the extension direction of the rotating roller 41. The scraper 34 is movably installed in the pressing groove 14. The end of the scraper 34 away from the pressing groove 14 is provided with a second guide surface 36 for guiding the scraper 34 into the pressing groove 14. A third spring 35 is provided between the scraper 34 and the pressing groove 14. The elastic force of the third spring 35 drives the scraper 34 to move toward the side away from the pressing groove 14.

[0063] Reference Figure 6 The scrapers 34 of the two adjacent sets of clamping members 33 are staggered. In this embodiment, the two ends of the scraper 34 overlap with the scrapers 34 of the adjacent clamping members 33, so that the two sets of clamping members 33 can keep the wallpaper flat. When the scraper 34 contacts the protruding part of the wall, it can enter the clamping groove 14 under the guidance of the second guide surface 36, reducing the possibility of the scraper 34 flattening the protruding part of the wall and damaging the wallpaper. The remaining scrapers 34 can keep the wallpaper flat, thereby improving the flattening effect of the wallpaper.

[0064] The sponge strip 31 has an installation groove 37, the extension direction of which is the same as the extension direction of the sponge strip 31; the scrapers 34 of the two sets of clamping members 33 are inserted into the installation groove 37. In this embodiment, both the sponge strip 31 and the housing 1 are provided with magnetic attractants. The magnetic attractants are provided on the sponge strip 31 and the housing 1. By energizing the magnetic attractants, wallpaper with magnetic powder can be attracted to the side of the housing 1 with the opening 12, thereby improving the stability of the wallpaper fixed to the side wall of the housing 1.

[0065] By incorporating the sponge strip 31, the contact between the scraper 34 and the wallpaper can be increased, improving the smoothing effect and reducing damage to the wallpaper during the scraping process. Furthermore, when the scraper 34 enters the pressing groove 14 at a wall protrusion, the flexible sponge strip 31 can still maintain contact with the wallpaper at the protrusion, further enhancing the smoothing effect of the scraping component on the sponge strip 31.

[0066] The implementation principle of Embodiment 1 of this application is as follows:

[0067] When wallpapering the wall, first switch the rotating roller 41 to the first state using the positioning rod 52, and then rotate the wallpaper out between the rotating roller 41 and the inner wall of the opening 12. At this time, multiple first extrusion components can evenly apply the glue with magnetic powder to the inner side of the wallpaper. Then switch the rotating roller 41 to the second state and activate the magnetic attraction of the sponge strip 31 to fix the wallpaper to the side of the housing 1 with the opening 12.

[0068] Then, the linear module 21 can move the housing 1 to the top and abut the side of the housing 1 with the opening 12 against the wall. At this time, the sponge strip 31 located on the upper surface of the housing 1 can abut against the junction of the wall and the top of the wall. When the end of the wallpaper is moved to the top of the wall, the wallpaper is glued from the junction of the wall and the top of the wall. This reduces the need for workers to first pull out part of the wallpaper and climb to the top of the wall through scaffolding to glue it to the wall, thus improving work efficiency and reducing safety hazards.

[0069] Next, the linear module 21 moves the housing 1 from the top to the bottom of the wall. During this process, as the wallpaper is pulled out from the opening 12 of the housing 1, the second adhesive applicator applies adhesive to the wallpaper, ensuring it adheres to the wall. Furthermore, the scraper 34 smooths the wallpaper and removes air bubbles between the wallpaper and the wall, improving the wallpaper's adhesion. This device can perform the processes of applying adhesive, pasting, and removing air bubbles from the wallpaper, further improving the efficiency of wallpapering.

[0070] Example 2:

[0071] This application discloses a wallpaper mounting auxiliary device.

[0072] Reference Figure 7 The difference between Embodiment 2 and Embodiment 1 is that: the bottom of the housing 1 has an opening 12, that is, the bottom of the storage cavity 11 and the opening 12 are both connected to the outside; a moving component 6 is installed inside the housing 1, which is used to move the rotating roller 41 into the storage cavity 11 and abut against the inner wall of the storage cavity 11, and make the lowest point of the rotating roller 41 higher than the top wall of the opening 12.

[0073] The moving component 6 includes a second cylinder 61, a third cylinder 62, and a sliding plate 63. The sliding plate 63 is slidably mounted on the inner wall of the storage cavity 11, and the sliding direction of the sliding plate 63 is in the same direction as the height direction of the housing 1. The second cylinder 61 is fixed on the sliding plate 63, and the movable plug of the second cylinder 61 is connected to the rotating roller 41. By controlling the movable plug of the second cylinder 61, the rotating roller 41 can be moved into the storage cavity 11. The third cylinder 62 is fixed on the movable plug, and the movable plug of the third cylinder 62 is fixed to the sliding plate 63. By controlling the third cylinder 62, the sliding plate 63 can be moved in the storage cavity 11, and the rotating roller 41 can be moved and abut against the inner wall of the storage cavity 11.

[0074] Reference Figure 8 A first cylinder 71 is slidably installed inside the storage cavity 11. The sliding direction of the first cylinder 71 is the same as the sliding direction of the rotating roller 41. A cutting blade 7 is fixed to the movable plug of the first cylinder 71. A wave groove 72 is opened on the surface of the cutting blade 7. The two ends of the wave groove 72 are respectively connected to the two sides of the cutting blade 7. A fixing rod 73 is fixed on the inner wall of the storage cavity 11 near the opening 12. The fixing rod 73 passes through the wave groove 72 and is exposed inside the storage cavity 11.

[0075] When the housing 1 completes the wallpapering process, the cylinder blade is driven by the first cylinder 71 to move closer to one side of the wallpaper. As the moving component 6 moves the rotating roller 41 into the storage cavity 11, the wallpaper can bend and come into contact with the inner wall of the storage cavity 11. At this time, the cutting blade 7 can cut the bent part of the wallpaper. And the fixing rod 73 moves in the wave groove 72, which can move the cutting blade 7 to improve the cutting effect on the wallpaper and enable the housing 1 to have the function of cutting wallpaper, further improving work efficiency.

[0076] The implementation principle of Embodiment 2 of this application is as follows:

[0077] When the linear module 21 drives the housing 1 to move to the bottom of the wall, the bottom of the opening 12 can abut against the floor, allowing the wallpaper to be pasted to the bottom of the wall, thus improving the wallpapering effect. Furthermore, the wallpaper is cut by the cutting blade 7 located on the inner wall of the storage cavity 11, allowing part of the wallpaper to be pasted to the floor. During subsequent floor tiling and other work, the wallpaper can be partially clamped between the floor tiles and the floor, reducing the possibility of the bottom of the wallpaper curling up and further improving the wallpapering effect.

[0078] This application discloses a method for constructing a wallpaper pasting auxiliary device, which specifically includes the following steps:

[0079] S1 installs the wallpaper into the storage cavity 11 from the side of the housing 1, and converts the conversion roller to the second state through the conversion component 5, so that the side of the extrusion block 421 with the first guide surface 424 is exposed to the outside; then the end of the wallpaper is pulled out from between the rotating roller 41 and the inner wall of the opening 12, so that the glue with magnetic powder is evenly applied to the inner side of the wallpaper.

[0080] S2 energizes the magnetic suction component to fix the wallpaper with magnetic powder to the side of the housing 1 near the opening 12. The rotating roller 41 is switched to the first state by the conversion component 5, so that the second extrusion component is exposed to the outside.

[0081] S3 starts the lifting mechanism 2 to raise the housing 1 to the top and abut against the wall. At this time, the end of the wallpaper with magnetic powder is pasted from the junction of the wall and the top of the wall.

[0082] S4 restarts the lifting assembly to lower the housing 1, and the wallpaper is pulled out from between the rotating roller 41 and the side wall of the opening 12; at this time, the rotating roller 41 rotates and the second glue application assembly applies glue to the inner side wall of the wallpaper, so that the wallpaper is pasted to the wall, and the scraping mechanism 3 scrapes out the air between the wallpaper and the wall;

[0083] When the S5 housing 1 moves to the bottom, the moving component 6 is activated to move the rotating roller 41 to the storage cavity 11, so that the wallpaper is clamped between the rotating roller 41 and the inner wall of the storage cavity 11; and the housing 1 continues to descend so that the inner wall of the opening 12 abuts against the floor.

[0084] S6 starts the first cylinder 71, causing the cutting blade 7 to cut the wallpaper, completing the wallpapering process.

[0085] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
