Description

Technical Field

[0001] This utility model belongs to the technical field of dipping machine, and particularly relates to a glue cleaning device for a dipping machine. Background Technology

[0002] As a key processing equipment in textiles, composite materials, and electronic components, the core function of a dipping machine is to impregnate substrates with adhesive solution in a dipping tank to impart weather resistance, abrasion resistance, insulation, or adhesive properties. During the dipping process, the adhesive solution is affected by temperature changes, residual impurities on the substrate, and prolonged standing, which can easily lead to the formation of a solidified or semi-solidified adhesive residue layer on the inner wall of the dipping tank. If not cleaned in time, the residual adhesive will gradually accumulate, not only reducing the effective volume of the dipping tank and affecting the adhesive circulation efficiency, but also mixing with newly injected adhesive solution to form impurities, resulting in uneven coating of the substrate, surface defects, and a significant reduction in product qualification rate.

[0003] The inventors discovered that at least the following problems remain unresolved in existing technologies: Traditional small-scale dipping machines mostly rely on manual cleaning methods such as hand-held scrapers, wire brushes, or solvent wiping. On the one hand, the inner wall of the dipping tank is often curved or has a deep cavity structure, making it difficult for manual operation to reach hidden areas such as edges and corners, easily creating blind spots for cleaning. On the other hand, the motor-driven scraper moves along the tank wall to clean the adhesive, but the scraper will gradually wear down due to long-term friction with the tank wall, or the dipping tank may undergo slight deformation after long-term use, easily causing gaps to form between the scraper and the tank wall. Residual adhesive can leak through these gaps, and the cleaning effect decreases sharply over time, requiring frequent disassembly and replacement of the scraper, increasing maintenance costs and downtime.

[0004] Therefore, we propose a glue-cleaning device for a glue-dipping machine, which can solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned technical problems by providing a glue-cleaning device for a glue-dipping machine, which achieves the effect of automatically adjusting the adhesion of the scraper strip.

[0006] In view of this, the present invention provides a glue cleaning device for a glue dipping machine, including a glue dipping tank and a housing, wherein a drive rod is rotatably connected inside the housing via a bearing, and scraper strips are vertically arranged on both sides of the drive rod;

[0007] A compensation mechanism is provided on one side of the scraper to push the scraper against the inner wall of the impregnation tank;

[0008] A drive mechanism is provided above the drive rod for driving the scraper to rotate;

[0009] The outer side of the housing is equipped with a fixing component for fixing the housing to the impregnation tank.

[0010] Furthermore, the fixing assembly includes four sets of brackets fixedly installed on the front, rear, left and right sides of the housing. The brackets are inverted L-shaped, with a screw threaded through and connected to the end of the bracket away from the housing. A fixing block is fixedly installed on the end of the screw close to the housing, and the fixing block abuts against the outside of the impregnation tank.

[0011] Furthermore, the compensation mechanism includes a spring for pushing the scraper to move. Two sets of connecting cylinders are horizontally fixedly installed on both sides of the drive rod. A piston is slidably connected inside the connecting cylinder. Two sets of adjusting rods are horizontally fixedly installed on the side of the scraper near the drive rod. The end of the adjusting rod away from the scraper is placed inside the connecting cylinder and fixedly connected to the middle of the piston. The spring is disposed inside the connecting cylinder.

[0012] Furthermore, the two ends of the spring are fixedly connected to the inner wall of the connecting cylinder and the piston, respectively, and the dimensions of the connecting cylinder and the adjusting rod are matched, and the dimensions of the scraper are matched with the dimensions of the impregnation tank.

[0013] Furthermore, the fixing assembly includes a large bevel gear mounted on the upper end of the drive rod, a small bevel gear meshing with the large bevel gear, and a control rod for driving the small bevel gear to rotate. The control rod is rotatably connected to one side of the housing via a bearing. One end of the control rod located inside the housing is fixedly connected to the middle of the small bevel gear. A handwheel is fixedly mounted on the end of the control rod away from the small bevel gear, and the small bevel gear and the large bevel gear are matched with the dimensions of the housing.

[0014] Furthermore, a support block is vertically fixedly installed on the upper surface of one of the brackets, and the control rod is rotatably connected to the support block through a bearing.

[0015] The beneficial effects of this utility model are:

[0016] 1. The housing is secured above the glue-dipping tank via a fixing component on the outside, ensuring stability during the glue-cleaning process. A compensation mechanism on one side of the scraper continuously provides thrust, ensuring the scraper remains firmly pressed against the inner wall of the glue-dipping tank. This prevents loose contact due to wear from long-term use or minor deformation of the tank wall, guaranteeing thorough glue removal. A drive mechanism above the drive rod rotates the rod around the bearing, simultaneously causing the scrapers on both sides to move in a circular motion along the inner wall of the tank. Through friction between the scrapers and the inner wall, residual glue is completely scraped away, achieving a convenient and quick glue-cleaning function. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1 to 2 A glue-cleaning device for a glue-dipping machine includes a glue-dipping tank 1 and a housing 10. A drive rod 11 is rotatably connected to the inside of the housing 10 via bearings. Scrapers 12 are vertically arranged on both sides of the drive rod 11. A compensation mechanism is provided on one side of the scraper 12 to push the scraper 12 against the inner wall of the glue-dipping tank 1. A drive mechanism is provided above the drive rod 11 to drive the scraper 12 to rotate. A fixing component is provided on the outside of the housing 10 for fixing the housing 10 to the glue-dipping tank 1.

[0023] In this technical solution, the housing 10 is fixed above the glue-dipping tank 1 by a fixing component on the outside of the housing 10, ensuring the stability of the device during the glue-cleaning process. A compensation mechanism on one side of the scraper 12 continuously provides thrust, always pushing the scraper 12 to tightly contact the inner wall of the glue-dipping tank 1, preventing the scraper 12 from wearing down due to long-term use or minor deformation of the inner wall of the glue-dipping tank 1, thus ensuring thorough glue cleaning. A drive mechanism above the drive rod 11 drives the drive rod 11 to rotate around the bearing. The drive rod 11 simultaneously drives the scrapers 12 on both sides to move in a circular motion along the inner wall of the glue-dipping tank 1. Through the friction between the scraper 12 and the inner wall, the residual glue on the inner wall of the glue-dipping tank 1 is completely scraped away, achieving the glue-cleaning function quickly and easily.

[0024] In this embodiment, the fixing assembly includes four sets of brackets 13 fixedly installed on the front, rear, left and right sides of the housing 10. The brackets 13 are inverted L-shaped. The end of the bracket 13 away from the housing 10 is threaded through and connected to a screw 14. The end of the screw 14 close to the housing 10 is fixedly installed with a fixing block 15. The fixing block 15 is pressed against the outside of the impregnation tank 1.

[0025] In this technical solution, the housing 10 is placed at a preset position on the upper end of the impregnation tank 1, so that the free ends of the four sets of brackets 13 correspond to the outer side walls of the impregnation tank 1. Then, the screw 14, which is threaded and passes through the end of the bracket 13 away from the housing 10, is rotated. During the rotation, the screw 14 moves axially towards the impregnation tank 1, thereby pushing the fixing block 15, which is fixedly installed at its end, to move synchronously, so that the fixing block 15 is tightly pressed against the outer side wall of the impregnation tank 1. Through the static friction between the fixing block 15 and the outer wall of the impregnation tank 1, and the symmetrical support of the four sets of brackets 13, the housing 10 is stably fixed on the impregnation tank 1. When disassembling, the screw 14 is rotated in the opposite direction to make the fixing block 15 detach from the outer wall of the impregnation tank 1, thus realizing the separation of the housing 10 from the impregnation tank 1, which is convenient and quick.

[0026] In this embodiment, the compensation mechanism includes a spring 19 for pushing the scraper 12 to move. Two sets of connecting cylinders 16 are horizontally fixed on both sides of the drive rod 11. A piston 17 is slidably connected inside the connecting cylinder 16. Two sets of adjusting rods 18 are horizontally fixed on the side of the scraper 12 near the drive rod 11. The end of the adjusting rod 18 away from the scraper 12 is placed inside the connecting cylinder 16 and fixedly connected to the middle of the piston 17. The spring 19 is disposed inside the connecting cylinder 16.

[0027] In this technical solution, a spring 19 installed inside the connecting cylinder 16 provides a continuous adhesive thrust to the scraper 12. When the scraper 12 shortens slightly due to wear, or when there are minor protrusions or depressions on the inner wall of the glue-impregnation tank 1, the spring 19 will expand and contract based on its own elastic deformation characteristics, ensuring that the scraper 12 is in close contact with the inner wall of the glue-impregnation tank 1, achieving dynamic compensation and ensuring the glue removal effect. It should be noted that a sealing ring is provided on the outer side of the piston 17. When the scraper 12 is removed from the glue-impregnation tank 1, the elastic force of the spring 19 can push the piston 17 to move inside the connecting cylinder 16. Furthermore, the piston 17 can automatically clean the glue that has entered the connecting cylinder 16, and the piston 17 has a sealing function to prevent glue from adhering to the outer side of the spring 19 and affecting the normal use of the spring 19.

[0028] In this embodiment, the two ends of the spring 19 are fixedly connected to the inner wall of the connecting cylinder 16 and the piston 17, respectively, and the dimensions of the connecting cylinder 16 and the adjusting rod 18 are matched, and the dimensions of the scraper 12 and the impregnation tank 1 are matched.

[0029] In this technical solution, the scraper 12 is matched with the size of the glue-impregnation tank 1 to ensure that the length and width of the scraper 12 are completely matched with the cleaning area of ​​the inner wall of the glue-impregnation tank 1, covering the entire inner wall surface that needs to be cleaned.

[0030] In this embodiment, the fixing assembly includes a large bevel gear 2 mounted on the upper end of the drive rod 11, a small bevel gear 22 meshing with the large bevel gear 2, and a control rod 21 for driving the small bevel gear 22 to rotate. The control rod 21 is rotatably connected to one side of the housing 10 through a bearing. One end of the control rod 21 located inside the housing 10 is fixedly connected to the middle of the small bevel gear 22. A handwheel 23 is fixedly installed on the end of the control rod 21 away from the small bevel gear 22, and the small bevel gear 22 and the large bevel gear 2 are matched with the size of the housing 10.

[0031] In this technical solution, the operator turns the handwheel 23, which drives the small bevel gear 22 to rotate via the control lever 21. Since the small bevel gear 22 meshes with the large bevel gear 2, the rotation of the small bevel gear 22 will drive the large bevel gear 2 to rotate, which in turn drives the drive rod 11 connected to the large bevel gear 2 to rotate around its own axis. When the drive rod 11 rotates, the scraper strips 12 on both sides of it move in a circular motion along the inner wall of the glue-impregnation tank 1 in sync with the drive rod 11, ultimately achieving the glue-scraping action.

[0032] In this embodiment, a support block 24 is vertically fixedly installed on the upper surface of a set of brackets 13, and the control rod 21 is rotatably connected to the support block 24 through a bearing.

[0033] In this technical solution, during the operation of the drive mechanism, one end of the control rod 21 is rotatably connected to the housing 10, and the other end is supported by the support block 24. The two-point support structure can effectively prevent the control rod 21 from bending or shaking due to its long length or uneven force, thereby ensuring the meshing accuracy of the small bevel gear 22 and the large bevel gear 2.

[0034] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
