Description

Technical Field

[0001] This invention belongs to the technical field of wallpaper production equipment, specifically relating to a device for uniformly spraying a wear-resistant layer on wallpaper. Background Technology

[0002] With the rapid development of the wallpaper industry, consumers are increasingly demanding higher durability and aesthetics from wallpaper. The abrasion layer, as a core structure for improving the lifespan and surface texture of wallpaper, directly determines the market competitiveness of wallpaper products through its spraying quality. Currently, the spraying of wallpaper abrasion layers is mostly done using traditional manual spraying or simple semi-automatic spraying equipment. Existing spraying devices generally have many technical defects, making it difficult to meet the needs of large-scale, high-quality production.

[0003] In existing technologies, wallpaper abrasion layer spraying is mostly done using fixed nozzles or unidirectional moving spraying, which has problems such as uneven spraying, missed spraying, double spraying, and incomplete edge spraying. In addition, the paint is prone to sedimentation and layering, resulting in inconsistent thickness of the abrasion layer on the wallpaper surface after spraying, and insufficient abrasion resistance in some areas. At the same time, static electricity and dust on the wallpaper surface easily attract paint, affecting the adhesion of the abrasion layer, and subsequent peeling and flaking are likely to occur, seriously affecting the quality of wallpaper products. Summary of the Invention

[0004] The purpose of this invention is to provide a simple and reasonably designed uniform spraying device for wallpaper wear-resistant layer in order to solve the above problems.

[0005] The present invention achieves the above objectives through the following technical solutions: A uniform spraying device for abrasion-resistant layer of wallpaper includes a base, on which are provided an unwinding assembly, a tensioning assembly cooperating with the unwinding assembly, a conveying mechanism cooperating with a conveying mechanism, a painting assembly cooperating with the conveying mechanism, a drying assembly cooperating with the painting assembly, and a winding assembly cooperating with the painting assembly. The conveying mechanism includes a conveyor frame fixedly installed on the top of the base. The inner side wall of the conveyor frame is rotatably connected to a plurality of arrayed conveyor rollers. One end of each conveyor roller rotatably passes through the side wall of the conveyor frame. Each conveyor roller is fitted with a synchronization component, which consists of a staggered array of synchronous belts and synchronous pulleys. A second servo motor that drives the corresponding conveyor roller to rotate is fixedly installed on the side wall of the conveyor frame. The painting assembly includes two first guide rails respectively fixedly installed on both sides of the top of the conveyor frame. A first slider is slidably connected to the outer side wall of each of the two first guide rails. A fixed seat is fixedly installed on the top of each of the two first sliders. A second guide rail is fixedly installed between the two fixed seats. A second slider is slidably connected to the outer side wall of the second guide rail. A spray head is fixedly installed on the inner side wall of the second slider. An ion air bar that cooperates with the spray head is fixedly installed on the rear side wall of the two fixed seats.

[0006] As a further optimization of the present invention, a second lead screw located below the second guide rail is rotatably connected between the two fixed seats. The bottom of the second slider is threaded onto the outer side wall of the second lead screw. A fourth servo motor for driving the second lead screw to rotate is fixedly installed on the side wall of one of the fixed seats.

[0007] As a further optimization of the present invention, a second lead screw located below the second guide rail is rotatably connected between the two fixed seats. The bottom of the second slider is threaded onto the outer wall of the second lead screw. A fourth servo motor for driving the second lead screw to rotate is fixedly installed on the side wall of one of the fixed seats. A first lead screw is rotatably connected to the inner wall of one of the first guide rails. The bottom of the corresponding first slider slides through both sides of the first lead screw and is threaded onto the outer wall of the first lead screw. A third servo motor for driving the first lead screw to rotate is fixedly installed on the front wall of the corresponding first guide rail.

[0008] As a further optimization of the present invention, a paint mixing tank is fixedly installed on the side wall of the base, a metering pump is fixedly installed on the top of the paint mixing tank, the pumping end of the metering pump is fixedly connected to a material extraction pipe extending into the paint mixing tank, the delivery end of the metering pump is fixedly connected to a material conveying pipe, and the other end of the material conveying pipe is fixedly connected to the inlet end of the nozzle.

[0009] As a further optimization of the present invention, the drying assembly includes a U-shaped frame fixedly installed on the top of the base, a plurality of fans arranged in an array fixedly installed on the inner side wall of the U-shaped frame, and an electric heating wire communicating with the bottom of the plurality of fans fixedly installed on the inner side wall of the U-shaped frame.

[0010] As a further optimization of the present invention, the winding assembly includes a winding frame, and a winding roller is rotatably connected to the inner side wall of the winding frame. One end of the winding roller rotatably passes through the side wall of the winding frame. The winding assembly has the same structure as the unwinding assembly.

[0011] As a further optimization of the present invention, the tensioning assembly includes a tensioning adjustment seat fixedly installed on the top of the base. A tensioning roller is movably connected to the inner side wall of the tensioning adjustment seat. A rotating shaft is fixedly installed at both ends of the tensioning roller. A bushing is rotatably sleeved on the outer side wall of each of the two rotating shafts. An adjusting bolt with a thread penetrating the top of the tensioning adjustment seat is rotatably connected to the top of each of the two bushings.

[0012] As a further optimization of the present invention, a control panel is fixedly installed on the side wall of the U-shaped frame and electrically connected to the first servo motor, the third servo motor, the fan, the ion fan bar, the electric heating wire, the fourth servo motor, the metering pump, and the second servo motor.

[0013] The beneficial effects of this invention are as follows: 1. This invention effectively solves the above-mentioned problems through multiple design optimizations, significantly improving spraying accuracy and wear-resistant layer quality. First, the spraying assembly adopts a bidirectional moving structure, with the first and second guide rails set perpendicularly. The spray head can move flexibly along the width and length of the wallpaper. Combined with the precise control of the third and fourth servo motors, the moving speed and distance of the spray head can be precisely adjusted to adapt to the spraying needs of wallpapers of different widths and lengths, ensuring that every area of ​​the wallpaper surface is evenly sprayed without missed areas, double spraying, or edge spraying. This solves the problem of uneven spraying caused by limited spray head movement in existing technologies. Second, an ion bar is installed to remove impurities before spraying. The static electricity and dust on the wallpaper surface are eliminated, preventing dust from adhering to the wallpaper surface and affecting the spraying quality. Static electricity also eliminates interference with paint atomization, ensuring that the paint adheres evenly to the wallpaper surface, improving the adhesion of the wear-resistant layer, and reducing the risk of subsequent peeling and flaking. Furthermore, the paint mixing tank continuously stirs the paint, preventing sedimentation and stratification, ensuring uniform paint concentration. Combined with a metering pump, precise control of the feed rate avoids paint waste and ensures consistent spraying thickness, further improving the uniformity of the wear-resistant layer. This keeps the thickness error of the wear-resistant layer on the wallpaper surface within a reasonable range, significantly outperforming existing technologies and improving the qualification rate and service life of wallpaper products.

[0014] 2. This invention, through its modular design and adjustable structure, significantly improves the adaptability of the device, broadening its application range and increasing its flexibility. Regarding wallpaper width adaptation, the first guide rail of the spraying assembly can move the spray head along the width of the wallpaper. Combined with the precise control of the first servo motor, it can flexibly adapt to wallpapers of different widths without requiring replacement of the spray head or modification of the spraying structure. Operation is convenient; simply adjust the spray head movement range via the control panel. Regarding wallpaper thickness and material adaptation, the second servo motor can precisely control the rotation speed of the conveyor rollers, thereby adjusting the wallpaper conveying speed to meet the spraying needs of wallpapers of different thicknesses and materials. This avoids uneven spraying and wear resistance caused by excessively fast or slow conveying speeds. This addresses issues such as weak adhesion of the coating layer. The tensioning component allows for precise adjustment of tension via adjusting bolts, flexibly adjusting the bonding force for wallpapers of different thicknesses and materials to ensure the wallpaper remains flat and taut at all times, preventing loosening, wrinkles, or stretching deformation. Furthermore, the paint mixing tank can store different types of wear-resistant paint, the metering pump can precisely adjust the feed rate, and the drying component can adjust the heating temperature according to the paint characteristics and wallpaper material, further enhancing the device's adaptability. It can meet the wear-resistant layer spraying needs of wallpapers of different specifications and materials without requiring equipment replacement or major modifications, reducing production investment, increasing production flexibility, and solving the problems of poor adaptability and narrow applicability in existing technologies.

[0017] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0018] Example 1: As Figure 1 - Figure 4 As shown, a uniform spraying device for abrasion-resistant layers of wallpaper includes a base 1, which serves as the core load-bearing foundation of the entire device. The base 1 is constructed from high-strength steel, ensuring a stable structure and strong load-bearing capacity, guaranteeing that the device operates without shaking or deformation. It stably supports all components, including the unwinding assembly 2, tensioning assembly 12, conveying mechanism 5, painting assembly 9, drying assembly, rewinding assembly, paint mixing tank 3, and control panel 4, providing a stable working platform for the entire wallpaper abrasion-resistant layer spraying process. The base 1 is equipped with the unwinding assembly 2, the tensioning assembly 12 (which works in conjunction with the unwinding assembly 2), the conveying mechanism 5 (which works in conjunction with the tensioning assembly 12), the painting assembly 9 (which works in conjunction with the conveying mechanism 5), the drying assembly (which works in conjunction with the painting assembly 9), and the rewinding assembly (which works in conjunction with the painting assembly 9). All components work collaboratively to achieve automated continuous operation of the wallpaper from unwinding, tensioning, conveying, spraying, drying to rewinding, eliminating the need for manual intervention in each step and significantly improving production efficiency.

[0019] like Figure 1 and Figure 2As shown, the conveying mechanism 5 includes a conveyor frame 504 fixedly installed on the top of the base 1. The conveyor frame 504 provides stable installation support for components such as the conveying rollers 502 and the synchronization component 503, ensuring smooth conveying. Several arrayed conveying rollers 502 are rotatably connected to the inner wall of the conveyor frame 504. These conveying rollers 502 are parallel and evenly spaced, jointly carrying the wallpaper and driving it to move at a uniform speed, ensuring smooth and non-deviation-prone wallpaper conveying and guaranteeing uniform spraying. One end of each conveying roller 502 rotatably passes through the side wall of the conveyor frame 504, facilitating connection with the synchronization component 503 to achieve synchronous rotation. Each conveyor roller 502 is equipped with a synchronization component 503, which consists of a staggered array of synchronous belts and synchronous pulleys. The synchronous belts and synchronous pulleys mesh and drive each other, ensuring that all conveyor rollers 502 rotate at the same speed and in the same direction. This prevents wallpaper from wrinkling or shifting due to differences in the speed of the conveyor rollers 502, thus ensuring conveying stability. A second servo motor 501 is fixedly installed on the side wall of the conveyor frame 504 to drive the rotation of the corresponding conveyor roller 502. The second servo motor 501 provides power to the conveying mechanism 5 and can precisely control the speed of the conveyor rollers 502, thereby controlling the conveying speed of the wallpaper. This adapts to the spraying requirements of wallpapers of different thicknesses and materials, ensuring uniform spraying thickness.

[0020] like Figure 1 - Figure 4As shown, the spray painting assembly 9 is used to uniformly spray wear-resistant paint onto the surface of the wallpaper during transport to form a wear-resistant layer. It includes two first guide rails 901 that are respectively fixedly installed on both sides of the top of the conveyor frame 504. The two first guide rails 901 are arranged in parallel to provide a stable sliding guide for the first slider 904, ensuring that the first slider 904 moves smoothly and without deviation. The first slider 904 is slidably connected to the outer wall of each of the two first guide rails 901. The first slider 904 can move horizontally along the first guide rail 901, thereby driving the fixed seat 906, the second guide rail 907 and the spray head 909 to move synchronously, so as to realize the spraying of the spray head 909 along the width direction of the wallpaper. Each of the two first sliders 904 has a fixed base 906 fixedly installed on its top. The fixed base 906 is used to fix the second guide rail 907, the second lead screw 910 and other components, providing support for the movement of the nozzle 909. The second guide rail 907 is fixedly installed between the two fixed bases 906. The second guide rail 907 is set perpendicular to the first guide rail 901 and provides sliding guidance for the second slider 908, ensuring that the second slider 908 moves smoothly along the length of the wallpaper. A second slider 908 is slidably connected to the outer wall of the second guide rail 907. A nozzle 909 is fixedly installed on the inner wall of the second slider 908. The nozzle 909 is used to atomize the wear-resistant paint and spray it evenly onto the wallpaper surface. The nozzle of the nozzle 909 faces the wallpaper being transported to ensure accurate spraying. An ion air bar 911 that cooperates with the nozzle 909 is fixedly installed on the rear wall of the two fixed seats 906. The ion air bar 911 is used to remove static electricity and dust from the wallpaper surface before spraying to prevent dust from adhering to the wallpaper surface and affecting the spraying quality. At the same time, it eliminates the influence of static electricity on paint atomization to ensure that the wear-resistant layer is sprayed evenly and adhered firmly. A second lead screw 910 located below the second guide rail 907 is rotatably connected between the two fixed seats 906. The second lead screw 910 is set parallel to the second guide rail 907 and provides power for the movement of the second slider 908. The bottom of the second slider 908 is threaded onto the outer wall of the second lead screw 910. When the second lead screw 910 rotates, it drives the second slider 908 to slide along the second guide rail 907 through threaded transmission, thereby driving the nozzle 909 to move along the length of the wallpaper to achieve precise spraying. A fourth servo motor 905 that drives the second lead screw 910 to rotate is fixedly installed on the side wall of one of the fixed seats 906. The fourth servo motor 905 can precisely control the speed and rotation angle of the second lead screw 910, thereby precisely controlling the moving speed and distance of the nozzle 909 to ensure uniform spraying thickness, no missed spraying, and no double spraying. A first lead screw 903 is rotatably connected to the inner wall of one of the first guide rails 901. The first lead screw 903 is set parallel to the first guide rail 901 to provide power for the movement of the corresponding first slider 904.The bottom of the corresponding first slider 904 slides through both sides of the first lead screw 903 and is threaded onto the outer side of the first lead screw 903. When the first lead screw 903 rotates, it drives the first slider 904 to slide along the first guide rail 901 through threaded transmission, thereby driving the two fixed seats 906 and the nozzle 909 to move along the width of the wallpaper to adapt to the spraying needs of wallpapers of different widths. The front side wall of the corresponding first guide rail 901 is fixedly installed with a third servo motor 902 that drives the first lead screw 903 to rotate. The third servo motor 902 can precisely control the speed and rotation angle of the first lead screw 903, thereby precisely controlling the moving speed and distance of the nozzle 909 along the width of the wallpaper to ensure uniform spraying along the width of the wallpaper and no edge spraying.

[0021] like Figure 1 - Figure 4 As shown, a paint mixing tank 3 is fixedly installed on the side wall of the base 1. The paint mixing tank 3 is used to store wear-resistant paint and stir the paint to prevent sedimentation and stratification, ensure uniform paint concentration, and guarantee spraying quality. A metering pump 15 is fixedly installed on the top of the paint mixing tank 3. The metering pump 15 is used to accurately extract the wear-resistant paint from the paint mixing tank 3 and stably deliver the paint to the spray head 909. It can accurately control the feed amount, avoid paint waste, and ensure uniform spraying thickness. The liquid extraction end of the metering pump 15 is fixedly connected to a material extraction pipe 14 that extends into the paint mixing tank 3. The material extraction pipe 14 is used to extract the wear-resistant paint from the paint mixing tank 3, ensuring that the paint can smoothly enter the metering pump 15. The metering pump 15 is fixedly connected to the liquid delivery end of the conveying pipe 10, and the other end of the conveying pipe 10 is fixedly connected to the liquid inlet end of the nozzle 909. This is used to guide the paint conveyed by the metering pump 15 into the nozzle 909 to achieve a stable supply of paint. The conveying pipe 10 is made of a corrosion-resistant and non-aging material to prevent the paint from corroding the pipe and causing leakage.

[0022] like Figure 1 , Figure 2 and Figure 5As shown, the drying assembly is used to quickly dry the abrasion-resistant layer of the sprayed wallpaper, ensuring rapid curing of the abrasion-resistant layer, preventing it from flowing or sticking, and improving wallpaper processing efficiency and quality. The drying assembly includes a U-shaped frame 11 fixedly installed on the top of the base 1. The U-shaped frame 11 spans above the conveying mechanism 5, providing stable installation support for the fans 8 and electric heating wires 13, ensuring a smooth drying process. Several arrayed fans 8 are fixedly installed on the inner wall of the U-shaped frame 11. The fans 8 are used to evenly blow the heat generated by the electric heating wires 13 onto the wallpaper surface, accelerating the drying speed of the abrasion-resistant layer. The even distribution of several fans 8 ensures that the wallpaper surface is heated evenly, avoiding incomplete drying or over-drying in some areas that could cause the abrasion-resistant layer to crack. Electric heating wires 13, which are connected to the bottom of several fans 8, are fixedly installed on the inner wall of the U-shaped frame 11. The electric heating wires 13 are used to generate heat, providing a heat source for drying the wallpaper abrasion-resistant layer. The heating temperature can be adjusted according to the paint characteristics and production needs to ensure the drying effect while avoiding damage to the wallpaper due to excessive temperature.

[0023] like Figure 1 and Figure 2 As shown, the winding assembly is used to automatically wind up the dried wallpaper with the abrasion-resistant coating, facilitating subsequent cutting and packaging. The winding assembly includes a winding frame 6, which is fixedly mounted on the top of the base 1, providing stable support for the winding roller 7. The winding roller 7 is rotatably connected to the inner wall of the winding frame 6. The winding roller 7 is used to wind and wind the wallpaper. One end of the winding roller 7 rotatably passes through the side wall of the winding frame 6, facilitating connection with the drive component to achieve automatic winding. The winding assembly has the same structure as the unwinding assembly 2, which is used to hold the wallpaper roll to be coated, achieving automatic unwinding. Its structure is identical to the winding assembly, including a bracket, an unwinding roller, and a first servo motor 204 that drives the unwinding roller to rotate, ensuring that the unwinding speed matches the conveying speed and winding speed, preventing the wallpaper from loosening or stretching and deforming.

[0024] like Figure 1 and Figure 2As shown, the tensioning assembly 12 is used to adjust the tension of the wallpaper, preventing it from becoming loose or wrinkled during unrolling and conveying, ensuring the wallpaper is flat and providing a guarantee for uniform spraying. The tensioning assembly 12 includes a tension adjusting seat 1201 fixedly installed on the top of the base 1. The tension adjusting seat 1201 provides mounting support for components such as the tension roller 1205 and adjusting bolts 1204. The tension roller 1205 is movably connected to the inner wall of the tension adjusting seat 1201. The tension roller 1205 is arranged parallel to the conveying roller 502 and fits against the surface of the wallpaper to adjust the tension of the wallpaper. Both ends of the tension roller 1205 are fixedly mounted with rotating shafts 1202. The rotating shafts 1202 are used to connect the tension roller 1205 and the bushings 1203, ensuring that the tension roller 1205 can rotate flexibly and avoid abrasion of the wallpaper. The outer walls of the two rotating shafts 1202 are rotatably fitted with bushings 1203. The bushings 1203 are used to connect the rotating shafts 1202 and the adjusting bolts 1204, so that the rotational movement of the adjusting bolts 1204 is converted into the up-and-down movement of the tension roller 1205. The top of the two bushings 1203 is rotatably connected with adjusting bolts 1204 that are threaded through the top of the tension adjusting seat 1201. Rotating the adjusting bolts 1204 can drive the bushings 1203 to move up and down, thereby driving the tension roller 1205 to move up and down, adjusting the adhesion between the tension roller 1205 and the wallpaper, and achieving precise adjustment of the wallpaper tension.

[0025] like Figure 1 - Figure 5 As shown, a control panel 4 is fixedly installed on the side wall of the U-shaped frame 11. The control panel 4 is electrically connected to the first servo motor 204, the third servo motor 902, the fan 8, the ion air bar 911, the electric heating wire 13, the fourth servo motor 905, the metering pump 15, and the second servo motor 501, and is used for centralized control of the operation of the entire device. Operators can set the operating parameters of each component through the control panel 4, such as conveying speed, spraying speed, paint delivery volume, drying temperature, tension, etc., to achieve automated and precise operation of the device. Simultaneously, the operating status of each component can be monitored in real time, facilitating timely detection and handling of faults.

[0026] It should be noted that, during use, the installation of each component of this wallpaper wear-resistant layer uniform spraying device should be checked to ensure that the connections are firm and there is no looseness. Special attention should be paid to checking the synchronization of the conveying mechanism 5, the spraying accuracy of the nozzle 909, the adjustment flexibility of the tensioning component 12, the heating effect of the drying component, and the sealing of the pipeline. An appropriate amount of wear-resistant paint should be injected into the paint mixing tank 3, and the mixing function of the paint mixing tank 3 should be activated to ensure uniform paint application. The operating parameters of each component should be set through the control panel 4, including conveying speed, spraying speed, paint delivery volume, drying temperature, and tension. The wallpaper roll to be sprayed should be installed on the unwinding roller of the unwinding component 2. One end of the wallpaper should be sequentially passed over the tensioning roller 1205, the conveying roller 502, below the spraying component 9, and the drying component. Inside the component, it is finally fixed on the winding roller 7 of the winding assembly; the device is started, and a test spray is performed to check whether the wallpaper is conveyed smoothly, the tension is appropriate, the spraying is uniform, the drying is thorough, and the winding is neat. The parameters of each component are fine-tuned according to the test spray effect. After debugging, the device enters the normal operation state. The device is started, and the first servo motor 204 drives the unwinding roller to rotate, realizing automatic unwinding of the wallpaper; the adjusting bolt 1204 is rotated to adjust the height of the tensioning roller 1205 to ensure that the wallpaper is taut and flat; the second servo motor 204 drives the conveying roller 502 to rotate synchronously, driving the wallpaper to move at a uniform speed; the ion air bar 911 is started to remove static electricity and dust from the surface of the wallpaper; the metering pump 15 is started to draw paint through the extraction pipe 14. The paint in the mixing tank 3 is conveyed to the spray head 909 via the conveying pipe 10. The third servo motor 902 drives the first lead screw 903 to rotate, causing the spray head 909 to move along the width of the wallpaper. The fourth servo motor 905 drives the second lead screw 910 to rotate, causing the spray head 909 to move along the length of the wallpaper. The two work together to achieve uniform spraying of the wallpaper surface by the spray head 909. After spraying, the wallpaper enters the drying assembly along with the conveying mechanism 5. The fan 8 and the electric heating wire 13 are started to blow heat evenly onto the wallpaper, quickly drying the wear-resistant layer. After drying, the wallpaper continues to move with the conveying mechanism 5 and is automatically wound up by the winding roller 7 of the winding assembly, completing the spraying process of the wear-resistant layer of the wallpaper and realizing continuous batch production. The unwinding assembly 2 is inspected periodically. Check the rotation of the winding assembly, add lubricating oil in time to ensure smooth rotation; check the adjusting bolts 1204 and bushings 1203 of the tensioning assembly 12, tighten or replace them in time if they are loose or worn; check the synchronization assembly 503 of the conveying mechanism 5, adjust the tension in time if the timing belt is loose, and replace it in time if it is worn; clean the spray nozzle 909 regularly to avoid paint blockage and affect the spraying effect; check the material conveying pipe 10 and the material extraction pipe 14, repair or replace them in time if there is a leak; clean the paint mixing tank 3 regularly to avoid paint residue and clumping; check the fan 8 and electric heating wire 13 of the drying assembly, repair or replace them in time if there is a malfunction; calibrate the control accuracy of the control panel 4 regularly to ensure that the operating parameters of each component are accurate.When storing, turn off all power, clean the paint and dust from the device surface, roll up the wallpaper neatly, and place it in a dry, well-ventilated environment to prevent the device from getting damp or corroded.

[0027] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
