Description

Technical Field

[0001] This utility model relates to the field of exterior wall decorative panel processing technology, specifically to an adhesive application device for exterior wall decorative panel processing. Background Technology

[0002] A glue applicator, also known as a coating machine, glue scraper, or automatic glue sprayer, is a mechanical device primarily used to apply liquid glue to the surface of textiles, cardboard boxes, or leather. There are many types of glue applicators available, such as drum glue applicators, double-acting glue applicators, and dual-station lifting glue applicators. The coating machine uses air pressure to spray liquids such as glue or paint onto the desired product.

[0003] Chinese patent document CN202222800604.7, a related technology, discloses a glue applicator for applying adhesive to decorative panels. The process involves first starting a primary motor, whose output shaft drives a rotating rod, which in turn rotates a glue applicator cylinder. A measured amount of glue is then inverted into a glue container. The container is slid to allow the glue to flow evenly from the outlet onto the glue applicator cylinder through a second square groove. A scraper spreads the glue evenly across the surface of the cylinder. After the glue is dispensed, the glue container is moved above the square block to prevent... After the glue leaks out, place the decorative panel on the workbench and start motor number two. The output shaft of motor number two drives the lead screw to rotate, which in turn moves slider number one in the direction of the lead screw. The movement of slider number one moves the sliding table, which in turn moves slider number two on the positioning rod. The sliding table moves the rotating rod, which in turn moves the glue applicator. The spring ensures that as the glue applicator moves, it adheres to the workbench and applies glue evenly to the decorative panel. Apply glue to the decorative panel on the workbench.

[0004] Regarding the aforementioned technologies, the inventors believe that the following drawbacks exist: The device is fixedly installed on the inner wall of the sliding table using a scraper, and the distance between the scraper and the glue applicator is a fixed value. It can only guarantee the initial glue layer thickness through machining precision and cannot dynamically adjust according to the board specifications or process requirements. When processing exterior wall decorative panels of different thicknesses or surface roughness, for lightweight boards requiring a thin glue layer, the fixed scraper cannot actively reduce the distance, resulting in excessive glue residue and waste. For composite boards requiring a thick glue layer, the fixed scraper distance limits the amount of glue adhering, failing to meet bonding strength requirements. Furthermore, the glue uniformity is poor, lacking a dynamic stirring mechanism. Under the self-flowing glue supply method, fillers in the glue are prone to sedimentation and stratification, leading to uneven glue concentration on the surface of the glue applicator, affecting the bonding strength of the boards. Therefore, an glue applicator for processing exterior wall decorative panels is proposed to solve the above problems. Utility Model Content

[0005] The main objective of this invention is to provide an adhesive application device for processing exterior wall decorative panels, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an adhesive application device for processing exterior wall decorative panels, comprising a base, a buffer mechanism on the base, an operating table fixed at the upper end of the buffer mechanism, a sliding table slidably disposed on the base, a rotatable adhesive application roller disposed inside the sliding table, an adjustment mechanism disposed inside the sliding table, and a stirring mechanism disposed on the sliding table.

[0007] The adjustment mechanism includes a control panel and two fixed blocks located inside the sliding table. A threaded rod is rotatably installed between the two fixed blocks. Two slides are threadedly connected to the threaded rod. A support frame is fixed to the lower end of the slides. An extrusion roller is rotatably installed inside the support frame.

[0008] Furthermore, the threads at both ends of the threaded rod are opposite, and the two extrusion rollers are located on both sides of the coating roller.

[0009] Furthermore, one end of the threaded rod is driven to rotate by an external first motor, and one end of the glue-applying roller is driven by an external second motor.

[0010] Furthermore, an infrared sensor is fixed to the side wall of one of the support frames, and a control panel is fixed to the sliding table. The infrared sensor is electrically connected to the control panel and the external first motor.

[0011] Furthermore, the spraying mechanism includes a storage tank and a diversion pipe arranged laterally inside the sliding table. The lower end of the diversion pipe is fixed with multiple spray nozzles for spraying glue onto the coating roller.

[0012] Furthermore, a storage tank is fixed on the top of the sliding platform, and a pump body is provided on one side of the storage tank. The inlet and outlet ends of the pump body are connected to one side of the storage tank and a diversion pipe through infusion pipes, respectively.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] 1. This adhesive coating equipment for processing exterior wall decorative panels can automatically adjust the gap between the extrusion roller and the adhesive coating roller according to the thickness of the panel by adjusting the bidirectional threaded rod of the adjustment mechanism in conjunction with the infrared sensor. The reverse thread design at both ends of the threaded rod enables the two extrusion rollers to move synchronously and symmetrically, ensuring that the pressure on both sides of the adhesive coating roller is balanced. The infrared sensor monitors the position of the extrusion roller in real time, and the control panel drives the first motor to precisely adjust the number of rotations of the threaded rod to achieve the adhesive layer thickness according to the preset parameters.

[0015] 2. The adhesive application equipment for processing exterior wall decorative panels has a mixing mechanism that achieves real-time dynamic mixing of the adhesive through belt drive between the adhesive application roller and the rotating shaft. When the adhesive application roller rotates, the mixing rod in the storage tank is rotated synchronously through the rotating wheel and belt, so as to evenly disperse the precipitated filler.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 The adhesive application equipment for processing exterior wall decorative panels in this embodiment includes a base 1, a buffer mechanism 2 on the base 1, an operating table 6 fixed at the upper end of the buffer mechanism 2, a sliding table 7 slidably arranged on the base 1, a rotatable adhesive application roller 8 arranged inside the sliding table 7, an adjustment mechanism 4 arranged inside the sliding table 7, and a stirring mechanism 3 arranged on the sliding table 7.

[0022] The adjustment mechanism 4 includes a control panel 406 and two fixed blocks disposed inside the sliding table 7. A threaded rod 405 is rotatably installed between the two fixed blocks. Two slides 404 are threadedly connected to the threaded rod 405. A support frame 403 is fixed to the lower end of the slides 404. An extrusion roller 401 is rotatably installed inside the support frame 403.

[0023] The spraying mechanism 5 includes a storage tank 501 and a distribution pipe 503 horizontally arranged inside the sliding table 7. Multiple spray nozzles 502 for spraying adhesive onto the coating roller 8 are fixed to the lower end of the distribution pipe 503. During operation, the adhesive in the storage tank 501 is pumped into the distribution pipe 503 through a delivery pipe. After entering the distribution pipe 503, due to its special structural design, the adhesive is evenly distributed to each spray nozzle 502. Then, the spray nozzles 502 spray the adhesive onto the surface of the coating roller 8 at a set pressure and angle.

[0024] A storage tank 501 is fixed to the top of the sliding table 7. A pump body is installed on one side of the storage tank 501. The inlet and outlet ends of the pump body are connected to one side of the storage tank 501 and the diversion pipe 503 through infusion pipes, respectively. When the equipment starts working, the pump body starts, generating suction inside the pump body, which draws the glue in the storage tank 501 into the pump body through the infusion pipe. Then, the pump body pressurizes the glue and delivers it to the diversion pipe 503 through another infusion pipe. During this process, the pump body's speed and power can be adjusted according to actual needs to control the glue delivery flow rate and pressure.

[0025] When the adhesive coating thickness needs to be adjusted, the operator inputs the corresponding parameter commands on the control panel 406. Upon receiving the command, the control panel 406 starts the external first motor, which drives the threaded rod 405 to rotate. Because the threads at both ends of the threaded rod 405 are opposite, during rotation, the two slide blocks 404 move in opposite directions along the threaded rod 405, thereby moving the support frame 403 and the extrusion roller 401. By changing the gap between the extrusion roller 401 and the adhesive coating roller 8, the adhesive coating thickness can be adjusted.

[0026] In this design, the threads at both ends of the threaded rod 405 are opposite, and the two extrusion rollers 401 are located on both sides of the coating roller 8. When the external first motor drives the threaded rod 405 to rotate, the two slide blocks 404, which are threaded to the threaded rod 405, will move in opposite directions simultaneously due to the opposite directions of the threads at both ends. Because the support frame 403 fixed at the lower end of the slide block 404 is connected to the extrusion rollers 401 located on both sides of the coating roller 8, the two extrusion rollers 401 will move closer to or further away from each other synchronously.

[0027] Meanwhile, one end of the threaded rod 405 is driven to rotate by an external first motor, and one end of the glue-applying roller 8 is driven by an external second motor. During equipment operation, when it is necessary to adjust the glue thickness, the operator sends a command through the control panel 406. Upon receiving the command, the external first motor starts and drives the threaded rod 405 to rotate through transmission components such as couplings, thereby adjusting the position of the extrusion roller 401. At the same time, the external second motor runs continuously and stably, driving the glue-applying roller 8 to rotate through transmission devices such as belts 303, chains, or gears. During the glue application process, the glue-applying roller 8, driven by the second motor, evenly applies glue to the decorative panel at a constant speed.

[0028] In addition, an infrared sensor 402 is fixed to the side wall of one of the support frames 403, and a control panel 406 is fixed on the sliding table 7. The infrared sensor 402 is electrically connected to the control panel 406 and the external first motor. Before the equipment is put into operation, the operator sets the target coating thickness and other relevant parameters on the control panel 406. During the operation of the equipment, the infrared sensor 402 continuously monitors the distance between the two extrusion rollers 401 and transmits the real-time data to the control panel 406. The control panel 406 compares and analyzes the received distance data with the preset parameters. For example, if the gap between the extrusion rollers 401 corresponding to the preset coating thickness is 0.5mm, and the infrared sensor 402 detects that the current gap is 0.6mm, the control panel 406 determines that the gap is too large and the coating thickness needs to be reduced. At this time, the control panel 406 sends a command to the external first motor to control the first motor to rotate, which drives the threaded rod 405 to rotate, so that the two extrusion rollers 401 move closer to each other and reduce the gap. During the adjustment process, the infrared sensor 402 provides real-time feedback on the position changes of the extrusion roller 401, and the control panel 406 continuously adjusts the operation of the first motor based on the feedback data until the gap between the extrusion rollers 401 reaches the preset value, thereby achieving precise control of the coating thickness.

[0029] Please see Figure 1-3 In this embodiment, the stirring mechanism 3 includes a rotating wheel 304, a heating tube 305, and a rotating shaft 301 arranged horizontally in the storage tank 501. A stirring rod 302 is fixed on the rotating shaft 301. The coating roller 8 and the rotating shaft 301 are both fixed with rotating wheels 304. A belt 303 is connected between the two rotating wheels 304. The storage tank 501 is provided with a heating tube 305 for heating the glue. The heating tube 305 is made of high-temperature resistant and corrosion-resistant stainless steel. Its surface is specially treated to form a dense oxide film, which can effectively resist the corrosion of the glue chemicals.

[0030] A through-hole is provided on the side wall of the storage tank 501 corresponding to the position of the rotating shaft 301. The inner diameter of the through-hole is slightly larger than the outer diameter of the rotating shaft 301 to ensure that the rotating shaft 301 can pass through smoothly. After passing through the through-hole, one end of the rotating shaft 301 extends into the interior of the storage tank 501 and is fixedly connected to the stirring rod 302, while the other end extends into the outside of the storage tank 501 and is connected to the rotating wheel 304. To ensure the airtightness of the storage tank 501, a stepped sealing structure is provided at the through-hole: a fluororubber O-ring is installed on the side closer to the interior of the storage tank 501, and the gap between the rotating shaft 301 and the through-hole is filled by circumferential compression deformation to prevent glue leakage.

[0031] When the device is in operation, the coating roller 8 rotates under the drive of the second motor. The roller 304 on the coating roller 8 drives the roller 304 on the rotating shaft 301 to rotate via the belt 303, thereby causing the rotating shaft 301 and the stirring rod 302 to rotate. The stirring rod 302 rotates in the storage tank 501, stirring the glue and redispersing the precipitated filler into the glue to ensure uniform composition. At the same time, the heating tube 305 heats the glue according to preset temperature parameters. When the glue has a high viscosity at low temperatures, the heating tube 305 is activated to heat the glue to a suitable temperature, reducing the viscosity and increasing its fluidity, making it easier to spray and apply onto the decorative panel. Under the combined action of stirring and heating, the glue in the storage tank 501 remains in a uniform and suitable state, providing high-quality glue for the coating operation and ensuring the consistency and stability of the coating effect.

[0032] The working principle of the above embodiments is as follows:

[0033] Before starting the equipment, the operator places the exterior wall decorative panel to be glued on the operating table 6 and presets key parameters such as the glue thickness in the control panel 406. After the equipment starts, the external second motor starts first, driving the glue-applying roller 8 to rotate. At the same time, the glue-applying roller 8 drives the rotating shaft 301 of the stirring mechanism 3 to rotate via the belt 303, thereby causing the stirring rod 302 to stir the glue in the storage tank 501, preventing the filler in the glue from settling and separating. During this process, the heating tube 305 in the storage tank 501 heats the glue according to the preset temperature parameters, improving the glue's fluidity and bringing it to a suitable state for application.

[0034] Subsequently, the external first motor drives the threaded rod 405 to rotate. Since the threads at both ends of the threaded rod 405 are opposite, the two sliding blocks 404 connected to it drive the extrusion rollers 401 to move synchronously and symmetrically, thereby precisely adjusting the gap between the extrusion rollers 401 and the coating rollers 8 to achieve the required spacing for the preset coating thickness. During this period, the infrared sensor 402, fixed to the side wall of the support frame 403, monitors the distance between the two extrusion rollers 401 in real time and transmits the data to the control panel 406. The control panel 406 continuously analyzes the difference between this data and the preset parameters. Once it detects that the gap does not meet the requirements, it immediately sends a command to the external first motor to adjust the rotation of the threaded rod 405, realizing dynamic adjustment of the position of the extrusion rollers 401 and ensuring the accuracy of the coating thickness.

[0035] Once all components are ready, the sliding table 7 begins to slide on the base 1, moving the adhesive roller 8 above the decorative panel. At this time, the pump starts, delivering the well-stirred and appropriately heated adhesive from the storage tank 501 through the infusion pipe to the distribution pipe 503, and then evenly spraying it onto the surface of the adhesive roller 8 through the spray nozzle 502 at the lower end of the distribution pipe 503. As the adhesive roller 8 rotates, the adhesive on its surface is evenly applied to the surface of the decorative panel, completing the adhesive application process.
