Description

Technical Field

[0001] This invention relates to the field of home decoration tools, specifically to a wallpapering device and a wallpapering method. Background Technology

[0002] As the home renovation process progresses to the later beautification stage, wallpaper installation is a crucial step in enhancing the interior decoration effect, and its quality directly impacts the overall aesthetics of the space and the living experience. Currently, wallpaper installation tools on the market are mainly divided into two categories: manual operation tools and automated equipment tools. Both types of tools have significant limitations in practical application.

[0003] Manual wallpapering devices (such as traditional brushes, handheld rollers, and simple roll-up supports) require operators to manually complete a series of steps, including unrolling the wallpaper, applying adhesive, aligning, pressing, and cutting. This not only demands extensive experience from the operators to ensure a smooth, bubble-free finish, but also requires multiple people working together. The process is cumbersome and repetitive, leading to extended construction periods and generally low efficiency, making it difficult to meet the needs of large-scale renovation projects or high-efficiency construction. Furthermore, manual operation is susceptible to human error, frequently resulting in uneven adhesive application, wallpaper misalignment, and loose pressing, further affecting the quality of the wallpapering.

[0004] While highly automated wallpapering equipment (such as machinery integrating conveying, gluing, and pressing functions) can significantly improve installation efficiency and shorten construction cycles by replacing some manual operations through mechanical transmission structures, and is widely used in large-scale decoration projects, technical challenges remain in the core wallpaper cutting process. Specifically, the cutting mechanisms of these automated devices often use fixed blades or a single drive method. When cutting the wallpaper after it has been laid to the preset length, the wallpaper itself has a certain degree of flexibility and extensibility, and there are local tension differences between the wallpaper and the wall surface during installation. The moment the cutting blade contacts the wallpaper, tensile or shear stress can easily be generated. This stress can cause local wrinkles, edge bending, or slight stretching deformation of the wallpaper near the cutting blade, leading to deviations in the cutting trajectory and inaccurate cutting. Ultimately, this manifests as uneven edges on the cut wallpaper, resulting in local defects, curled corners, or excess material protruding from the cut length, damaging the overall integrity and aesthetics of the wall decoration. It may even require additional trimming, increasing construction steps and material waste.

[0005] Furthermore, some existing automated wallpapering devices suffer from insufficient coordination between the cutting mechanism and the pressing component. The cutting action and the wallpaper pressing progress are not synchronized, and the wallpaper lacks an effective temporary fixing and tension buffer structure at the moment of cutting, further exacerbating the problems of wallpaper wrinkles and cutting deviations. These defects not only affect the quality of decoration and construction but may also increase construction costs due to wallpaper waste, making it difficult to meet users' needs for high-precision, high-quality wallpapering. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a wallpapering device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a wallpapering device, characterized in that it comprises: A base, on the underside of which a predetermined number of casters are installed; A roller assembly, comprising a roller body and at least two support plates, wherein the roller body is rotatably connected to the two support plates, thereby enabling the roller body to rotate relative to the support plates, and wallpaper is wound on the roller body; A cutting mechanism through which wallpaper on the roller body passes; The bonding assembly includes a third electric cylinder, a support block, a first bonding roller, and a second bonding roller. The third electric cylinder is connected to the support block. Both ends of the first bonding roller and both ends of the second bonding roller are rotatably connected to a limiting block. The support block is connected to the limiting block via a preset number of support rods. The third electric cylinder drives the first bonding roller and the second bonding roller to rise and fall. Wallpaper that passes through and through the cutting mechanism enters the gap between the first bonding roller and the second bonding roller.

[0008] Furthermore, the cutting mechanism is mounted on the base and is located between the roller assembly and the bonding assembly; the cutting mechanism includes a basic frame, a cutter, and a preset number of cutter drive assemblies, which are distributed at both ends of the cutter. Each cutter drive assembly includes a second electric cylinder, a second adapter plate, and a second connector. The second electric cylinder has a second telescopic rod, which is connected to the second adapter plate. The second adapter plate is connected to the second connector, and the second connector is mounted together with the cutter, thereby enabling the second electric cylinder to drive the cutter to rise and fall.

[0009] Furthermore, the cutting mechanism also includes a pressing strip block and a preset number of strip block driving assemblies. The strip block driving assemblies are distributed at both ends of the pressing strip block. The pressing strip block includes a first electric cylinder, a first adapter, and a first connecting member. The first electric cylinder has a first telescopic rod, which is connected to the first adapter. The first adapter is connected to the first connecting member, and the first connecting member is connected to the pressing strip block, thereby enabling the first electric cylinder to drive the pressing strip block to rise and fall.

[0010] Furthermore, the cutting mechanism also includes a second wallpaper moving mechanism, which includes a second motor, a second stationary roller, a second rotating roller, a first pulley, a second pulley, a third pulley, and a belt. The third pulley is mounted on the second motor, so that the second motor drives the third pulley to rotate. The belt connects the first pulley, the second pulley, and the third pulley together, so that the second motor drives the second rotating roller to rotate. There is a preset gap between the second stationary roller and the second rotating roller, into which the wallpaper extends. When the second rotating roller rotates, it drives the wallpaper to move.

[0011] Furthermore, the second wallpaper moving mechanism also includes a second rotating rod and a tensioning wheel. The second rotating rod is rotatably mounted on the base frame, and the tensioning wheel is mounted on the base frame. The second pulley is mounted together with the second rotating rod. The tensioning wheel is in contact with the belt, so that the tensioning wheel causes at least a portion of the belt to bend, thereby tensioning the belt.

[0012] Furthermore, the cutting mechanism also includes a first wallpaper moving mechanism, which includes a first stationary roller, a first rotating roller, and a first motor. The first stationary roller is mounted on the base frame, and the first rotating roller is rotatably mounted on the base frame. The first motor is connected to the first rotating roller, thereby driving the first rotating roller to rotate. There is a first gap between the first rotating roller and the first stationary roller, and the wallpaper extends into the first gap and moves under the drive of the first rotating roller.

[0013] This application also provides a method for applying wallpaper using a wallpaper applicator, comprising the following steps: (1) Equipment arrangement: Move the wallpapering device to the wall to be wallpapered, adjust the position by using the casters under the base, ensure that the wallpapering components are parallel to the wall and the spacing is appropriate, and lock the casters to fix the device. (2) Wallpaper pre-installation: The whole roll of wallpaper is wound around the roller body. One end of the wallpaper passes through the first wallpaper moving mechanism and the second wallpaper moving mechanism of the cutting mechanism in sequence, and finally extends into the gap between the first and second posting rollers to complete the wallpaper insertion and positioning. (3) Wall preparation: Apply glue evenly to the wall surface to be wallpapered, ensuring that the glue covers the entire surface and the thickness is uniform, and avoid local missing glue affecting the bonding effect; (4) Equipment debugging: Check whether the clamping block and cutter of the cutting mechanism are in the initial rising position, and confirm that the power supply of the third electric cylinder, the first electric cylinder, the second electric cylinder, the first motor and the second motor are normal and the operation is smooth; (5) Start the paper feeding mechanism: Simultaneously start the first motor of the first wallpaper moving mechanism and the second motor of the second wallpaper moving mechanism. The first motor drives the first rotating roller to rotate, and the second motor drives the second rotating roller to rotate through the belt. Under the clamping drive of the two sets of rollers, the wallpaper is conveyed forward at a uniform speed and continuously supplies wallpaper between the first and second pasting rollers. (6) Start the wallpapering operation: The support block is raised and lowered by the third electric cylinder. The support block drives the limit block and the first and second wallpapering rollers to rise and fall synchronously through the support rod. Under the clamping of the two sets of wallpapering rollers, the wallpaper is tightly adhered to the pre-coated wall surface as the rollers rise and fall, realizing the vertical application of the wallpaper. During the application process, the rollers can help to remove air bubbles and ensure a tight fit. (7) Continuous installation feeding: With the continuous paper feeding of the wallpaper moving mechanism and the lifting action of the bonding component, the wallpaper is continuously laid according to the wall height until the top of the wallpaper reaches the preset height. (8) Wallpaper pressing and fixing: When the wallpaper is laid to the preset length, the strip drive assembly of the cutting mechanism is activated. The first electric cylinder drives the first telescopic rod to extend, and through the first adapter and the first connector, it drives the pressing strip to descend until the pressing strip presses the wallpaper horizontally to prevent the wallpaper from shifting or wrinkling during cutting. (9) Start the cutting action: After the wallpaper is fixed by pressing the strip, the cutter drive assembly is started immediately. The two sets of second electric cylinders drive the second telescopic rod to extend synchronously. The cutter is driven to descend through the second adapter plate and the second connector to cut the wallpaper horizontally along the preset trajectory on one side of the pressing strip, ensuring that the cut edge is neat. (10) Reset of cutting components: After cutting, the first electric cylinder and the second electric cylinder drive the pressing strip and the cutter to rise and reset, releasing the end of the wallpaper and preparing for the next section of installation; (11) Equipment relocation and adjustment: Unlock the casters, move the device to the next section of the wall to be covered, repeat the positioning steps in the pre-preparation stage, and ensure that it is aligned with the already covered wallpaper. (12) Repeated installation process: Follow the steps of “wallpaper delivery and installation stage - precise cutting stage” to complete the segmented installation and cutting of the entire wall in sequence until all wall surfaces are installed; (13) Equipment shutdown and storage: After the installation is completed, turn off the power to all drive components, fix the remaining roll of wallpaper, clean the residual glue on the surface of the device, and complete the equipment storage.

[0014] The beneficial effects of this application are as follows: The wallpaper application device provided by this application effectively solves many pain points of existing wallpaper application tools. The device integrates a roller assembly, a wallpaper moving mechanism, an application assembly, and a cutting mechanism, realizing integrated automated operation of wallpaper "unrolling-conveying-application-cutting". It eliminates the need for manual operation or multi-person collaboration, greatly simplifies the construction process, reduces repetitive labor intensity, and significantly improves application efficiency, meeting the high-efficiency construction needs of large-scale decoration projects. The core innovative cutting mechanism, through the coordinated design of the clamping strip and the cutter, horizontally fixes the wallpaper with the clamping strip before cutting, avoiding displacement and wrinkles during cutting. The synchronous drive at both ends of the cutter ensures horizontal cutting, completely solving the problems of inaccurate cutting and uneven edges in existing automated equipment. The double-roller application assembly, combined with the electric cylinder lifting mechanism, tightly adheres to the wall surface and removes air bubbles during application, ensuring a tight and airtight fit. In addition, the omnidirectional casters on the base facilitate flexible movement and positioning, adapting to different wall areas for wallpapering; the modular design of each component makes maintenance convenient, and the automated operation reduces the impact of human factors, reduces wallpaper waste and construction costs, and comprehensively improves the precision, quality and integrity of wallpapering, meeting users' needs for high-quality decoration.

[0021] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0022] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0023] Please refer to Figure 1-5 This application provides a wallpaper applicator (hereinafter referred to as "the applicator"), which includes: A base 1, with a predetermined number of casters 11 installed on its underside; A roller assembly, comprising a roller body 9 and at least two support plates 10, wherein the roller body 9 is rotatably connected to the two support plates 10, thereby enabling the roller body 9 to rotate relative to the support plates 10, and wallpaper is wound on the roller body 9. Cutting mechanism 2, through which wallpaper on the roller body 9 passes; The bonding assembly includes a third electric cylinder 3, a support block 4, a first bonding roller 6, and a second bonding roller 7. The third electric cylinder 3 is connected to the support block 4. Both ends of the first bonding roller 6 and both ends of the second bonding roller 7 are rotatably connected to a limiting block 5. The support block 4 is connected to the limiting block 5 via a predetermined number of support rods. The third electric cylinder 3 drives the first bonding roller 6 and the second bonding roller 7 to rise and fall. Wallpaper passing through and through the cutting mechanism 2 enters the gap between the first bonding roller 6 and the second bonding roller 7. Thus, as the third electric cylinder 3 drives the first bonding roller 6 and the second bonding roller 7 to rise and fall, the wallpaper can be applied to the wall. It should be noted that adhesive must be applied to the wall before applying the wallpaper.

[0024] Please refer to some embodiments of this application. Figure 1-5 The cutting mechanism 2 is mounted on the base 1 and is located between the roller assembly and the bonding assembly. The cutting mechanism 2 includes a base frame 21, a cutter 28, and a preset number of cutter drive assemblies 26. The cutter drive assemblies 26 are distributed at both ends of the cutter 28. Each cutter drive assembly 26 includes a second electric cylinder 261, a second adapter plate 262, and a second connector 263. The second electric cylinder 261 has a second telescopic rod 2610, which is connected to the second adapter plate 262. The second adapter plate 262 is connected to the second connector 263, and the second connector 263 is mounted together with the cutter 28, thereby enabling the second electric cylinder 261 to drive the cutter 28 to rise and fall. In this application, there are two cutter drive assemblies 26, which are respectively located at both ends of the cutter 28. The second electric cylinder 261 drives the second telescopic rod 2610 to extend and retract. The second telescopic rod 2610 drives the second adapter plate 262 and the second connector 263 to rise and fall together, so that the cutter 28 cuts off the wallpaper when it descends to the preset position.

[0025] Please refer to some embodiments of this application. Figure 1-5The cutting mechanism 2 further includes a pressing strip 27 and a preset number of strip driving assemblies 25. The strip driving assemblies 25 are distributed at both ends of the pressing strip 27. The pressing strip 27 includes a first electric cylinder 251, a first adapter 252, and a first connecting member 253. The first electric cylinder 251 has a first telescopic rod 2510, which is connected to the first adapter 252. The first adapter 252 is connected to the first connecting member 253, and the first connecting member 253 is connected to the pressing strip 27, thereby enabling the first electric cylinder 251 to drive the pressing strip 27 to rise and fall. In this application, there are two strip driving assemblies 25, respectively disposed at both ends of the pressing strip 27. When the first electric cylinder 251 drives the first telescopic rod 2510 to extend and retract, the first telescopic rod 2510 drives the first connecting piece 253 and the first adapter piece 252 to rise and fall together. When the pressing strip 27 descends to the preset position, the pressing strip 27 presses the wallpaper tightly, and then the cutter drive assembly 26 drives the cutter 28 to cut off the wallpaper.

[0026] Please refer to some embodiments of this application. Figure 1-5 The cutting mechanism 2 further includes a second wallpaper moving mechanism 24, which includes a second motor 249, a second stationary roller 241, a second rotating roller 242, a first pulley 244, a second pulley 245, a third pulley 246, and a belt 248. The third pulley 246 is mounted on the second motor 249, so that the second motor 249 drives the third pulley 246 to rotate. The belt 248 connects the first pulley 244, the second pulley 245, and the third pulley 246 together, so that the second motor 249 drives the second rotating roller 242 to rotate. There is a preset gap between the second stationary roller 241 and the second rotating roller 242. The wallpaper extends into this gap, and the second rotating roller 242 drives the wallpaper to move when it rotates. Thus, under the action of the second wallpaper moving mechanism 24, the wallpaper moves forward continuously. After the wallpaper is pasted, the strip drive mechanism 25 drives the pressing strip to press the wallpaper firmly, and then the cutter drive assembly drives the cutter to cut the wallpaper.

[0027] Please refer to some embodiments of this application. Figure 1-5 The second wallpaper moving mechanism 24 further includes a second rotating rod 243 and a tensioning wheel 247. The second rotating rod 243 is rotatably mounted on the base frame 21, and the tensioning wheel 247 is mounted on the base frame 21. The second pulley 245 is mounted together with the second rotating rod 243. The tensioning wheel 247 is in contact with the belt 248, so that the tensioning wheel 247 bends at least a portion of the belt 248, thereby tensioning the belt 248.

[0028] Please refer to some embodiments of this application. Figure 1-5 The cutting mechanism 2 further includes a first wallpaper moving mechanism 22, which includes a first stationary roller 221, a first rotating roller 222, and a first motor 223. The first stationary roller 221 is mounted on the base frame 21, and the first rotating roller 222 is rotatably mounted on the base frame 21. The first motor 223 is connected to the first rotating roller 222, thereby driving the first rotating roller 222 to rotate. There is a first gap 220 between the first rotating roller 222 and the first stationary roller 221. The wallpaper extends into the first gap 220 and moves under the drive of the first rotating roller 222.

[0029] This application also provides a method for applying wallpaper using a wallpaper applicator, comprising the following steps: (1) Equipment arrangement: Move the wallpapering device to the wall to be wallpapered, adjust the position by using the casters 11 under the base 1, and ensure that the bonding components (first bonding roller 6 and second bonding roller 7) are parallel to the wall and the spacing is appropriate. Lock the casters 11 to fix the device.

[0030] (2) Wallpaper pre-installation: The whole roll of wallpaper is wound on the roller body 9. One end of the wallpaper passes through the first wallpaper moving mechanism 22 (the first gap 220 between the first stationary roller 221 and the first rotating roller 222) and the second wallpaper moving mechanism 24 (the gap between the second stationary roller 241 and the second rotating roller 242) of the cutting mechanism 2 in sequence, and finally extends into the gap between the first pasting roller 6 and the second pasting roller 7 to complete the wallpaper insertion and positioning.

[0031] (3) Wall preparation: Apply glue evenly to the wall surface to be wallpapered, ensuring that the glue covers the entire surface and the thickness is uniform, and avoid missing glue in some areas to affect the bonding effect.

[0032] (4) Equipment debugging: Check whether the clamping block 27 and the cutter 28 of the cutting mechanism 2 are in the initial rising position, and confirm that the power supply of the drive components such as the third electric cylinder 3, the first electric cylinder 251, the second electric cylinder 261, the first motor 223, and the second motor 249 is normal and the operation is smooth.

[0033] (5) Start the paper feeding mechanism: Simultaneously start the first motor 223 of the first wallpaper moving mechanism 22 and the second motor 249 of the second wallpaper moving mechanism 24. The first motor 223 drives the first rotating roller 222 to rotate, and the second motor 249 drives the second rotating roller 242 to rotate through the belt 248 (the tension wheel 247 ensures that the belt 248 is tensioned and driven). Under the clamping drive of the two sets of rollers, the wallpaper is conveyed forward at a uniform speed, and wallpaper is continuously supplied between the first pasting roller 6 and the second pasting roller 7.

[0034] (6) Start the wallpapering operation: The support block 4 is driven to rise and fall by the third electric cylinder 3. The support block 4 drives the limit block 5 and the first and second wallpapering rollers 6 and 7 to rise and fall synchronously through the support rod. Under the clamping of the two sets of wallpapering rollers, the wallpaper is tightly adhered to the pre-coated wall surface during the rise and fall of the rollers, realizing the vertical application of the wallpaper. During the application process, the rolling of the rollers can help to expel air bubbles and ensure a tight fit.

[0035] (7) Continuous installation feeding: With the continuous paper feeding of the wallpaper moving mechanism and the lifting action of the bonding component, the wallpaper is continuously laid according to the wall height until the top of the wallpaper reaches the preset height.

[0036] (8) Wallpaper pressing and fixing: When the wallpaper is laid to the preset length (such as the top of the wall), the strip drive assembly 25 of the cutting mechanism 2 is activated. The first electric cylinder 251 drives the first telescopic rod 2510 to extend, and through the first adapter 252 and the first connector 253, it drives the pressing strip 27 to descend until the pressing strip 27 presses the wallpaper horizontally (the pressing position is located outside the cutting track), so as to avoid the wallpaper shifting and wrinkling during cutting.

[0037] (9) Start the cutting action: After the wallpaper is fixed by pressing the strip 27, the cutter drive assembly 26 is started immediately. The two sets of second electric cylinders 261 (located at both ends of the cutter 28) synchronously drive the second telescopic rod 2610 to extend. Through the second adapter plate 262 and the second connector 263, the cutter 28 is driven to descend and the wallpaper is cut horizontally along the preset trajectory on one side of the pressing strip 27 to ensure that the cut edge is neat.

[0038] (10) Reset of cutting components: After the cutting is completed, the first electric cylinder 251 and the second electric cylinder 261 drive the pressing strip 27 and the cutter 28 to rise and reset, releasing the end of the wallpaper and preparing for the next section of installation.

[0039] (11) Equipment relocation and adjustment: Unlock the caster wheel 11, move the device to the next section of the wall to be covered, repeat the positioning steps of the pre-preparation stage, and ensure that it is aligned with the already covered wallpaper.

[0040] (12) Repeated installation process: Follow the steps of “wallpaper delivery and installation stage - precise cutting stage” to complete the segmented installation and cutting of the entire wall in sequence until all wall surfaces are installed.

[0041] (13) Equipment shutdown and storage: After the installation is completed, turn off the power to all drive components, fix the remaining roll of wallpaper, clean the residual glue on the surface of the device, and complete the equipment storage.

[0042] The wallpaper application device provided in this application has the following technical advantages: it effectively solves many pain points of existing wallpaper application tools. The device integrates a roller assembly, a wallpaper moving mechanism, an application assembly, and a cutting mechanism, realizing integrated automated operation of wallpaper "unrolling-conveying-application-cutting."

Under the clamping of the two sets of wallpapering rollers, the wallpaper is tightly adhered to the pre-coated wall surface as the rollers rise and fall, realizing the vertical application of the wallpaper. During the application process, the rollers can help to remove air bubbles and ensure a tight fit. (7) Continuous installation feeding: With the continuous paper feeding of the wallpaper moving mechanism and the lifting action of the bonding component, the wallpaper is continuously laid according to the wall height until the top of the wallpaper reaches the preset height. (8) Wallpaper pressing and fixing: When the wallpaper is laid to the preset length, the strip drive assembly of the cutting mechanism is activated. The first electric cylinder drives the first telescopic rod to extend, and through the first adapter and the first connector, it drives the pressing strip to descend until the pressing strip presses the wallpaper horizontally to prevent the wallpaper from shifting or wrinkling during cutting. (9) Start the cutting action: After the wallpaper is fixed by pressing the strip, the cutter drive assembly is started immediately. The two sets of second electric cylinders drive the second telescopic rod to extend synchronously. The cutter is driven to descend through the second adapter plate and the second connector to cut the wallpaper horizontally along the preset trajectory on one side of the pressing strip, ensuring that the cut edge is neat. (10) Reset of cutting components: After cutting, the first electric cylinder and the second electric cylinder drive the pressing strip and the cutter to rise and reset, releasing the end of the wallpaper and preparing for the next section of installation; (11) Equipment relocation and adjustment: Unlock the casters, move the device to the next section of the wall to be covered, repeat the positioning steps in the pre-preparation stage, and ensure that it is aligned with the already covered wallpaper. (12) Repeated installation process: Follow the steps of "wallpaper delivery and installation stage - precise cutting stage" to complete the segmented installation and cutting of the entire wall in sequence until all wall surfaces are installed; (13) Equipment shutdown and storage: After the installation is completed, turn off the power to all drive components, fix the remaining roll of wallpaper, clean the residual glue on the surface of the device, and complete the equipment storage.
