Description

Technical Field

[0001] This utility model relates to the field of adhesive coating technology, and in particular to an adhesive coating device for composite boards. Background Technology

[0002] In the field of composite board production, adhesive application is a key process that determines the bonding strength and surface quality of the board. The adhesive application device used for composite boards needs to evenly apply the adhesive to the surface of the substrate to provide a reliable prerequisite for multi-layer board composite. With the large-scale application of composite boards in industries such as construction and home furnishing, the industry has put forward higher requirements for the ease of installation and operational stability of the device in order to meet the needs of efficient and high-quality manufacturing under large-scale production.

[0003] Existing adhesive coating devices typically employ a roller and scraper structure for coating. A power mechanism drives the roller to rotate, allowing the adhesive to adhere to the roller surface. The relative action between the scraper and the roller then completes the coating process on the substrate. For securing the device components, bolts and ordinary clips are commonly used, with manual alignment and tightening to connect the shaft and housing. The underlying technology revolves around adhesive transfer via mechanical transmission and fundamental mechanical connection methods.

[0004] However, when fixing components in existing devices, the traditional fixing methods such as bolts and clips are cumbersome. Not only is the installation time-consuming, but long-term use can also lead to loosening of the connection due to vibration and wear. This reduces the efficiency of device installation and maintenance, affects the stability of component connections, and consequently has an adverse effect on the accuracy of adhesive coating. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an adhesive scraping device for composite boards, which aims to improve the problems of cumbersome and loose roller fixing operation, low efficiency due to reliance on manual cleaning, and easy residue of impurities.

[0020] Reference Figure 4 and Figure 5The cleaning assembly includes a pipe 18, made of PVC, which delivers cleaning water to a spray nozzle 19. The outer wall of the pipe 18 is fixedly connected to the top of the bracket 1. The bottom of the pipe 18 is fixedly connected to the spray nozzle 19, which, in conjunction with a branch pipe 20, distributes water flow to each nozzle 21 evenly. The bottom of the spray nozzle 19 is fixedly connected to a branch pipe 20, which consists of multiple circular sections to cover the cleaning area of ​​each roller. The bottom of the branch pipe 20 is fixedly connected to multiple nozzles 21, made of copper, which form a high-pressure water flow to wash away residual adhesive on the roller. The coating assembly includes an adhesive roller. 22. The outer wall of the adhesive roller 22 is set inside the bracket 1. A glue-applying roller 23 is set on one side of the adhesive roller 22. The function of the glue-applying roller 23 is to transfer the adhesive to the surface of the composite board. A scraper roller 24 is set on one side of the glue-applying roller 23. The scraper roller 24 rotates in conjunction with the glued composite board to achieve the effect of leveling the glue layer and controlling the thickness. A motor 10 is fixedly connected to one end of the adhesive roller 22, the glue-applying roller 23 and the scraper roller 24. The motor 10 provides power to each roller and works with the controller 13 to achieve synchronous rotation. A controller 13 is fixedly connected to one side of the bracket 1. The controller 13 is used to adjust the working status of each component. Multiple buttons 14 are fixedly connected to one side of the controller 13. The buttons 14 are used to facilitate the input of operating commands by the operator. A second bracket 15 is fixedly connected to one side of the bracket 1. The second bracket 15 is made of stainless steel and is used to support the conveyor roller 16 and form a conveying channel with the bracket 1. Multiple conveyor rollers 16 are rotatably connected to the top of the bracket 15. The conveyor rollers 16 are driven by the motor 10 to rotate, so as to achieve the effect of continuous conveying of composite boards. A housing 11 is fixedly connected to the top of the bracket 1. The housing 11 is made of cold-rolled steel plate and is used to protect the internal worktable 12. The worktable 12 is rotatably connected inside the housing 11. The worktable 12 can be driven forward to send the composite board to be coated to the scraping area. An anti-overflow plate 25 is set on the top of the coating roller 23. One side of the anti-overflow plate 25 is rotatably connected to the top of the coating roller 23, and the other side of the anti-overflow plate 25 is rotatably connected to the top of the coating roller 23. The anti-overflow plate 25 is made of plastic and is used to prevent excess glue from overflowing from the coating roller 23 to reduce waste.

[0021] Working principle: When it is necessary to apply adhesive to the surface of the composite board, the adhesive is first poured onto the surface of the adhesive roller 22. The operator places the composite board to be coated on the workbench 12 at the top of the support 1. The device is started by the button 14 of the controller 13. The workbench 12 rotates and conveys the composite board to the coating area. After the motor 10 starts, it synchronously drives the adhesive roller 22, the coating roller 23 and the scraper roller 24 to rotate. The adhesive roller 22 carries the adhesive to the surface of the coating roller 23. The coating roller 23 then evenly adheres the adhesive to the surface of the composite board it passes. The anti-overflow plate 25 at the top can prevent the adhesive from overflowing. At the same time, the scraper roller 24 contacts the surface of the composite board, scrapes off the excess adhesive and smooths the adhesive layer to ensure uniform coating thickness. The coated composite board is then conveyed to the placement area by the conveyor roller 16 at the top of the support 2. When it is necessary to clean each roller, connect the water source to the pipe 18. The water flows through the pipe 18 into the spray pipe 19, and then through the branch pipe 20 to multiple nozzles 21. The nozzles 21 spray water to rinse the roller body. If the roller body needs to be replaced, press the button 6 on the top of the shaft 8. The button 6 compresses the spring 7 and drives the fixing rod 17 to rotate, so that the locking block 3 is disengaged. Then, pull the locking case 2 out of the old roller along the guide rail 9 on the outer wall of the shaft 8. When replacing the new roller, slide the locking case 2 into the guide rail 9 so that the positioning rod 4 is aligned and engaged with the locking groove 5 on the inner wall of the shaft 8. After releasing the button 6, the spring 7 returns to its original position, and the button 6 locks the locking block 3 to complete the fixation.
