AI Technical Summary
Existing scraper mechanisms are difficult to adapt to adhesives of different viscosities, resulting in uneven coating effects, especially for adhesives with higher viscosity, making it difficult to achieve a uniform and smooth adhesive layer.
A direct-scraping coating head scraper mechanism was designed. The relative position of the scraper and the coating roller is adjusted by an inclined plate installed between two wall panels and a rodless cylinder. Combined with a stirring rod to stir the glue, the glue viscosity is ensured to be consistent. The rodless cylinder drives the inclined plate to rotate around the center of the bearing seat, and the scraper angle is adjusted to adapt to glues of different viscosities.
This technology allows for adjustment of the relative position between the scraper and the coating roller based on the viscosity of the adhesive, ensuring uniformity of the adhesive layer during the coating process and improving the coating effect.

Abstract
Description
Technical Field
[0001] This utility model relates to a scraper mechanism for a straight coating head. Background Technology
[0002] In the coating process, it is required that the adhesive layer applied to the film be uniform and consistent. Therefore, it is essential to ensure that the adhesive on the coating roller is even and flat to guarantee the uniformity of the adhesive layer after coating on the film. For this purpose, coating machines are generally equipped with a straight-scraper coating head scraper mechanism, which scrapes the adhesive on the coating roller evenly and smoothly.
[0003] In existing scraper mechanisms, the scraper usually approaches the glue-applying roller by translating, and the scraper position is fixed relative to the glue-applying roller, resulting in a single function, which is only suitable for scraping glue for specific types of glue.
[0004] In practical applications, the viscosity of the adhesive applied to the coating roller varies depending on the coating requirements. Especially for some adhesives with higher viscosity, this type of horizontal scraper is difficult to achieve the effect of evenly scraping the adhesive layer on the coating roller, thus affecting the coating effect. Utility Model Content
[0005] The technical problem to be solved by this utility model is: in order to overcome the shortcomings of the prior art, this utility model provides a straight scraping head scraper mechanism that is suitable for adhesives of different viscosities and ensures that the adhesive layer coated on the film is uniform and consistent.
[0006] The technical solution adopted by this utility model to solve its technical problem is: a straight-scraping coating head scraper mechanism, installed between two wall panels set apart, with a glue-applying roller rotatably installed between the two wall panels, a glue storage tank for storing glue installed between the wall panels, and a stirring rod for stirring glue rotatably installed inside the glue storage tank, an inclined plate fixed to the bottom surface of the glue storage tank, and a lip for applying glue to the glue-applying roller between the inclined plate and the glue storage tank, with bearing seats at both ends of the inclined plate for synchronously moving the glue-applying rollers close to or far apart, the inclined plate being rotatably connected to the bearing seats via a rotating shaft, a scraper at the end of the inclined plate near the glue-applying roller, and a rodless cylinder installed at the upper end of the wall panel to drive the inclined plate to rotate around the center of the bearing seat to realize the change of the scraper position.
[0007] Specifically, the inner sides of the two wall panels are fixed with supports, and a connecting steel pipe is fixed between the supports. A linear guide rail is installed on the upper end face of the supports, and a dual-axis cylinder is installed on the slider of the linear guide rail. The bearing seat is fixed to the upper end face of the dual-axis cylinder, and a cylinder connecting plate is fixed on the rear side of the supports. The upper end of the cylinder connecting plate is fixed to the piston rod of the dual-axis cylinder. When the dual-axis cylinder is started, since its piston rod and cylinder connecting plate are in a fixed state, the dual-axis cylinder moves on the linear guide rail, thereby driving the bearing seat to move the glue-applying rollers close to or far from each other.
[0008] Furthermore, a mounting base is fixed to the upper end of the wall panel, and the rodless cylinder is installed between the mounting bases. Connecting blocks are fixed to both ends of the rodless cylinder, and an optical shaft is fixed to the connecting block. A connecting rod is movably connected to the lower end of the optical shaft, and the lower end of the connecting rod is movably connected to the inclined plate. Thus, the rodless cylinder pushes the inclined plate to rotate around the center of the bearing seat to adjust the position of the hanging plate.
[0009] Furthermore, in order to achieve the rotation of the stirring rod, a motor base is fixed on the bottom left side of the inclined plate, a stirring motor is installed on the motor base, a motor pulley is installed on the motor shaft of the stirring motor, and a shaft pulley that is connected to the motor pulley is fixed on the left end of the stirring rod.
[0010] The beneficial effects of this utility model are as follows: Based on the different viscosities of the adhesive, this utility model uses a rodless cylinder to drive an inclined plate to rotate around the center of the bearing seat at a certain angle to adjust the relative position between the scraper and the coating roller, so that the scraper can scrape the adhesive on the coating roller at a better angle, in order to obtain a better coating effect. This makes it convenient to select adhesives of different viscosities according to the coating requirements during the coating process, and ultimately achieve a uniform adhesive layer on the film.

A glue storage tank 3 is installed between the wall panels 1, and a stirring rod 4 for agitating the glue is rotatably mounted inside the glue storage tank 3. A motor base 19 is fixed to the bottom left side of the inclined plate 5, and a stirring motor 20 is mounted on the motor base 19. A motor pulley 21 is mounted on the motor shaft of the stirring motor 20. A shaft pulley 22, which is connected to the motor pulley 21, is fixed to the left end of the stirring rod 4. The stirring rod 4 continuously agitates the glue to prevent solidification and ensures consistent glue viscosity.
[0018] The bottom surface of the glue storage tank 3 is fixed with an inclined plate 5. There is a lip between the inclined plate 5 and the glue storage tank 3 for glue to flow into the surface of the glue coating roller 2. The two ends of the inclined plate 5 are respectively provided with bearing seats 6 for synchronously moving the glue coating roller 2 in a similar or distant manner. The inclined plate 5 is rotatably connected to the bearing seats 6 through a rotating shaft 7. The end of the inclined plate 5 near the glue coating roller 2 has a scraper 8.
[0019] The inner sides of the two wall panels 1 are each fixed with a support 10, and a connecting steel pipe 11 is fixed between the supports 10. A linear guide rail 12 is installed on the upper end face of the support 10, and a dual-axis cylinder 13 is installed on the slider of the linear guide rail 12. The bearing seat 6 is fixed to the upper end face of the dual-axis cylinder 13. A cylinder connecting plate 14 is fixed to the rear side of the support 10, and the upper end of the cylinder connecting plate 14 is fixed to the piston rod of the dual-axis cylinder 13.
[0020] The upper end of the wall panel 1 is equipped with a rodless cylinder 9 that drives the inclined plate 8 to rotate around the center of the bearing seat 6 to realize the position change of the scraper 8. Specifically, the upper end of the wall panel 1 is fixed with a mounting base 15, and the rodless cylinder 9 is installed between the mounting bases 15. The two ends of the rodless cylinder 9 are respectively fixed with connecting blocks 16, and an optical axis 17 is fixedly connected to the connecting block 16. The lower end of the optical axis 17 is movably connected with a connecting rod 18, and the lower end of the connecting rod 18 is movably connected to the inclined plate 5.
[0021] According to different adhesive viscosities, this utility model uses a rodless cylinder 9 to drive the inclined plate 5 to rotate around the center of the bearing seat 6 at a certain angle to adjust the relative position between the scraper 8 and the coating roller, so that the scraper 8 can scrape the adhesive on the coating roller 2 at a better angle, in order to obtain a better coating effect. This makes it convenient to select adhesives of different viscosities according to the coating requirements during the coating process, and finally achieve a uniform adhesive layer on the film.
