Description

Technical Field

[0001] This invention relates to the field of gypsum board production equipment technology, and in particular to a gypsum board gluing device. Background Technology

[0002] Gypsum board is a type of board made from building gypsum and paperboard. It has advantages such as light weight, sound insulation, and heat insulation. The production of gypsum board usually involves processes such as mixing, drying, and gluing. The gluing process involves applying white glue to the surface of the paperboard to bond it to the paperboard underneath, forming a complete gypsum board.

[0003] The existing gypsum board gluing process generally involves using pipes to deliver white glue directly onto the gypsum board paper to bond it to the gypsum board paper. However, this process often suffers from unstable glue dispensing from the pipes, and the glue outlet position is difficult to adjust. This easily leads to uneven gluing, with some areas having more glue than others, which negatively impacts the quality of the final gypsum board product.

[0004] Therefore, the existing gypsum board gluing process is unstable. Summary of the Invention

[0010] In some specific embodiments, the tightening assembly includes: a locking screw, which passes through the rotating housing and one end of the locking screw can engage with the scraper to fix the position of the scraper; and a tightening spring, which is disposed in the rotating cavity and one end of the tightening spring is connected to the scraper to tighten the scraper.

[0011] In some specific embodiments, the moving component includes: a fixed plate disposed on one side of the pallet; a moving shell slidably sleeved on the fixed plate, and a rotating component disposed on the moving shell so that the moving shell can drive the scraper to move along the length direction of the fixed plate; and a transmission component disposed on one side of the fixed plate along the length direction, the transmission component being connectable to a transmission belt so that the fixed plate can be driven to rise and fall along the height direction of the fixed plate by a first rotating motor.

[0012] In some specific embodiments, the fixed plate has symmetrical grooves on both sides in the height direction, and the two ends of the grooves extend along the length direction of the fixed plate; the movable shell has symmetrical pulleys on both sides in the height direction, the pulleys can be embedded in the grooves, and the pulleys are connected to a second rotating motor so that the pulleys can drive the movable plate to move.

[0013] In some specific embodiments, the fixed plate is symmetrically provided with limiting grooves on both sides in the height direction, and the two ends of the limiting grooves extend along the length direction of the fixed plate; the movable shell is symmetrically provided with protrusions on both sides in the height direction, and the protrusions can be embedded in the limiting grooves to restrict the movement direction of the movable plate.

[0014] In some specific embodiments, the pressing part is also provided with a camera component, which can detect the position of the paper on the gypsum board passing through the tray; the camera component is connected to the pressing part through a controller so that the pressing part can adjust the position of the squeegee so that the squeegee is aligned with the appropriate position of the paper on the gypsum board.

[0015] The beneficial effects of this invention are:

[0016] The gypsum board gluing device of the present invention uses a scraper positioned directly opposite the tray to apply white latex to the surface of the paper conveyed onto the gypsum board, ensuring uniform distribution of the white latex. Simultaneously, the pressing part drives the scraper to move along the height and length of the pressing part, thereby enabling targeted application of white latex to areas on the paper of the gypsum board that have not been evenly coated. This ensures that the white latex is evenly applied to the paper of the gypsum board, thus guaranteeing the quality of the finished gypsum board. Attached Figure Description

[0027] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4A gypsum board gluing device includes: a mixing tank 100, a conveying section 200, and a pressing section 300. The mixing tank 100 is used to mix and store white glue. The mixing tank 100 is connected to a screw pump 120 via a conveying pipe 110. The output end of the screw pump 120 is provided with a glue outlet pipe 121, allowing the screw pump 120 to dispense white glue. The conveying section 200 can convey paper sheet on the gypsum board. A pallet 210 is provided on the conveying section 200 so that the paper sheet on the gypsum board can pass through one side of the pallet 210. The pressing section 300 is located on one side of the conveying section 200, and the glue outlet pipe 121 passes through the pressing section 300 and faces the pallet 210, so that the glue outlet pipe 121 can dispense white glue onto the paper sheet on the gypsum board. A scraper 310 is provided on the pressing section 300, and the scraper 310 is positioned directly opposite the tray 210. The paper on the gypsum board can pass between the tray 210 and the scraper 310, so that the scraper 310 can apply white latex to the paper on the gypsum board. The scraper 310 can move along the height and length of the pressing section 300, so that the scraper 310 can evenly apply white latex to the paper on the gypsum board.

[0028] Specifically, the pallet 210 on the conveyor section 200 is vertically arranged, allowing the gypsum board paper passing over it to also pass vertically. The adhesive pressing section 300 is located on one side of the pallet 210, and the scraper 310 is located on the side of the adhesive pressing section 300 closest to the pallet 210, allowing the scraper 310 to be positioned directly opposite the pallet 210. This ensures the gypsum board paper can pass between the pallet 210 and the scraper 310, facilitating the scraper 310 to apply adhesive to appropriate areas on the gypsum board paper. The mixing tank 100 has a hollow internal structure, allowing operators to pre-mix white glue in specific proportions within the mixing tank 100. A conveying pipe 110 is connected to the bottom of the mixing tank 100. The end of the conveying pipe 110 away from the mixing tank 100 is connected to a screw pump 120. The screw pump 120 can extract white glue from the mixing tank 100. The output end of the screw pump 120 is connected to a glue outlet pipe 121, so that the extracted white glue can be output through the glue outlet pipe 121. The end of the glue outlet pipe 121 away from the screw pump 120 is provided with an outlet. By passing the glue outlet pipe 121 through the glue pressing part 300, the outlet of the glue outlet pipe 121 is positioned in the direction of the pallet 210, so that the extracted white glue can be output onto the surface of the plasterboard paper passing through the pallet 210. Furthermore, the outlet of the glue dispensing tube 121 is positioned directly opposite the side of the scraper 310 near the tray 210, allowing the white glue to be first dispensed onto the scraper 310. As the paper on the plasterboard continuously passes between the tray 210 and the scraper 310, the scraper 310 directly applies the white glue to the surface of the paper on the plasterboard. Compared to directly dispensing the white glue onto the paper on the plasterboard, this method makes it easier for the white glue to be evenly applied to the paper on the plasterboard. Meanwhile, the pressure-pressing section 300 drives the scraper 310 to move along the height and length of the pressure-pressing section 300. This means the pressure-pressing section 300 can drive the scraper 310 to move along the height and length of the support plate 210, facilitating timely adjustment of the scraper 310's position relative to the support plate 210. This allows the scraper 310 to apply adhesive to any position on the gypsum board paper, ensuring even application of white glue and guaranteeing the quality of the final gypsum board. The conveying pipe 110 can be multi-headed, allowing the mixing tank 100 to connect to multiple screw pumps 120, enabling simultaneous adhesive application to multiple sets of gypsum board paper and improving application efficiency.

[0029] In some specific embodiments of the present invention, the conveying unit 200 includes: a frame 220, lower rotating rollers 230, and upper rotating rollers 240. The frame 220 is hollow to form a passage cavity through which paper on a gypsum board can pass. Multiple lower rotating rollers 230 are rotatably disposed at the bottom of the passage cavity, and are evenly arranged along the width of the frame 220, with a gap between each adjacent pair of upper rotating rollers 240. Multiple upper rotating rollers 240 are rotatably disposed at the top of the passage cavity, and are evenly arranged along the width of the frame 220, with each upper rotating roller 240 located between each adjacent pair of lower rotating rollers 230. A tray 210 is disposed in the middle of the frame 220 so that paper on a gypsum board can pass through one side of the tray 210 by winding around the lower rotating rollers 230 and the upper rotating rollers 240.

[0030] Specifically, the frame 220 includes two symmetrically arranged frames with a certain gap between them, forming a passage cavity for paper from the plasterboard to pass through. Multiple lower rotating rollers 230 are evenly arranged between the bottoms of the two frames along the width of the frame 220. The two ends of each lower rotating roller 230 extend along the length of the frame 220 and are rotatably connected to the bottoms of the frames on both sides via rotating seats. Four upper rotating rollers 240 are evenly arranged between the tops of the two frames along the width of the frame 220. The two ends of each upper rotating roller 240 extend along the length of the frame 220 and are rotatably connected to the tops of the frames on both sides via rotating seats. Each upper rotating roller 240 is located between each pair of adjacent lower rotating rollers 230. A support plate 210 is vertically arranged in the middle of the frame 220, and its sides can be fixedly connected to the frames on both sides via brackets. When the paper on the plasterboard enters the passage cavity, it first moves towards the top of the frame 220 and towards the first upper rotating roller 240 by passing around the first lower rotating roller 230. Then, it moves towards the bottom of the frame 220 and towards the second lower rotating roller 230 by passing around the first upper rotating roller 240, and so on. This allows the paper on the plasterboard to move vertically, so that the plasterboard can pass through one side of the support plate 210 located in the middle of the frame 220, which facilitates the scraper 310 to apply the paper on the plasterboard.

[0031] In some specific embodiments of the present invention, the pressing part 300 includes a rotating assembly 320 and a moving assembly 330. A scraper 310 is disposed on the rotating assembly 320. The rotating assembly 320 is rotatably disposed on the moving assembly 330, so that the rotating assembly 320 can drive the scraper 310 to rotate together on the moving assembly 330. This allows for a significant adjustment of the angle between the scraper 310 and the tray 210, i.e., between the scraper 310 and the paper on the plasterboard, through the rotation of the rotating assembly 320. Simultaneously, the moving assembly 330 can drive the rotating assembly 320 to move along the height and length directions of the moving assembly 330, i.e., the height and length directions of the tray 210, thereby driving the scraper 310 to move together through rotation. The scraper 310 and the rotating component 320 are also rotatably connected, so that the relative rotation between the scraper 310 and the rotating component can be used to slightly adjust the angle between the scraper 310 and the support plate 210, that is, between the scraper 310 and the paper on the plasterboard, so that the scraper 310 can apply the paper on the plasterboard more evenly.

[0032] In some specific embodiments of the present invention, the rotating assembly 320 includes a rotating shell 321 and a tightening assembly 322. The interior of the rotating shell 321 is hollow, thereby forming a rotating cavity in which the scraper 310 can be rotatably connected. A fixed shaft is provided inside the rotating cavity, and one end of the scraper 310 is rotatably sleeved on the fixed shaft, so that the scraper 310 can rotate about the fixed shaft. The rotating shell 321 is rotatably connected to the moving assembly 330, so that the rotating shell 321 can drive the scraper 310 to rotate together. The tightening component 322 is mounted on the rotating housing 321 and is connected to the scraper 310. The tightening component 322 can fix the scraper 310, thereby preventing the scraper 310 from easily rotating during operation and affecting the application of paper to the gypsum board. In addition, the tightening component 322 can also tighten the blade of the scraper 310, so that the scraper 310 maintains a suitable tightness. This allows the scraper 310 to apply paper to the gypsum board with appropriate force, avoiding poor application effect due to insufficient application force or tearing of the paper on the gypsum board due to excessive application force.

[0033] In some specific embodiments of the present invention, the tightening assembly 322 includes a locking screw and a tightening spring. The locking screw passes through the bottom wall of the rotating housing 321 and is threadedly connected to the rotating housing 321. As the locking screw is continuously tightened, one end of the locking screw can engage with the scraper 310, thereby fixing the position of the scraper 310. The tightening spring is disposed in the rotating cavity. One end of the tightening spring is fixed to the rotating housing 321, and the other end of the tightening spring is connected to the blade of the scraper 310. As the scraper 310 rotates, the elastic force of the tightening spring will continuously change, pulling the scraper 310 tight, thereby always maintaining the scraper 310 at a suitable tightness relative to the paper on the plasterboard, and thus maintaining the application force of the scraper 310 on the paper on the plasterboard.

[0034] In some specific embodiments of the present invention, the moving component 330 includes: a fixed plate 331, a moving shell 332, and a transmission component 333. The fixed plate 331 is disposed on one side of the support plate 210. The moving shell 332 is slidably sleeved on the fixed plate 331, so that the moving shell 332 can slide along the length direction of the fixed plate 331, and the moving shell 332 can be positioned directly opposite the support plate 210. The rotating component 320 is disposed on the side of the moving shell 332 near the support plate 210, so that the moving shell 332 can drive the scraper 310 to move together along the length direction of the fixed plate 331. The transmission component 333 is disposed on one side of the fixed plate 331 along the length direction, and the transmission component 333 can be connected to a transmission belt, so that the first rotating motor 3333 can drive the transmission belt to move, thereby driving the fixed plate 331 to rise and fall along the height direction of the fixed plate 331, thereby achieving the purpose of driving the scraper 310 to rise and fall along the height direction of the fixed plate 331. Multiple symmetrical grooves 3311 are distributed on both sides of the fixed plate 331 along its height direction. Both ends of each groove 3311 extend along the length of the fixed plate 331. Multiple axles 3321 are symmetrically arranged on both sides of the movable shell 332 along its height direction. Both ends of each axle 3321 extend along the width of the fixed plate 331. Multiple pulleys 3322 are fitted onto each axle 3321. These pulleys 3322 correspond one-to-one with the grooves 3311, allowing them to fit perfectly into the grooves. The rotation of the pulleys 3322 drives the movable shell 332 to move the scraper 310. The axles 3321 are connected to the output of a second rotating motor, which drives the axles 3321 to rotate together with the pulleys 3322. This rotation of the pulleys 3322 then drives the movable plate to move the scraper 310. The movable housing 332 has a mounting housing 3324 on the side near the tray 210. The mounting housing 3324 is hollow, allowing the rotating housing 321 to be rotatably fitted inside, thus completing the installation of the scraper 310. The mounting housing 3324 is connected to the movable housing 332 via a support rod 3325, creating a certain gap between the rotating housing 321 mounted on the mounting housing 3324 and the movable housing 332. This ensures sufficient rotation angle for the scraper 310 and provides enough space for the dispensing tube 121. The transmission assembly 333 includes a mounting plate 3331, a rotating shaft 3332, and a first rotating motor 3333. The mounting plate 3331 is provided on one side of the fixed plate 331 along the length direction. Multiple rotating shafts 3332 are rotatably disposed on the side of the mounting plate 3331 away from the fixed plate 331. The multiple rotating shafts 3332 are evenly arranged along the height direction of the fixed plate 331. The multiple rotating shafts 3332 cooperate with each other, so that the transmission belt can be wound around the multiple rotating shafts 3332.The first rotating motor 3333 is mounted on the mounting plate 3331. The output end of the first rotating motor 3333 passes through the mounting plate 3331 and is connected to the rotating shaft 3332. The first rotating motor 3333 can drive multiple rotating shafts 3332 to rotate, thereby driving the transmission belt to move, and thus realizing the lifting and lowering of the scraper 310.

[0035] In some specific embodiments of the present invention, the two sides of the fixed plate 331 in the height direction are symmetrically provided with limiting grooves 3312, and the two ends of the limiting grooves 3312 extend along the length direction of the fixed plate 331. The two sides of the movable shell 332 in the height direction are symmetrically provided with protrusions 3323, which can be embedded in the limiting grooves 3312, thereby restricting the movement direction of the movable plate and preventing the scraper 310 from deviating when it moves.

[0036] In some specific embodiments of the present invention, the pressing part 300 is also provided with a camera component, which can detect the position of the paper on the plasterboard passing through the tray 210. The camera component is connected to the first rotating motor 3333 and the second rotating motor through a controller, so that the scraper 310 can be moved or raised and lowered according to the position of the paper on the plasterboard, so that the scraper 310 can be aligned with the appropriate position of the paper on the plasterboard, thereby ensuring that the white glue is applied evenly.
