Description

Technical Field

[0001] This utility model relates to the field of film coating technology, specifically to a film coating adhesive scraping device. Background Technology

[0002] In industries such as metal processing and packaging printing, lamination is a key step in improving the surface protection and appearance quality of products. By covering the surface of metal plates (such as stainless steel plates and aluminum plates) and cardboard (such as carton boards and decorative cardboard) with an adhesive film, the wear resistance, water resistance, and corrosion resistance of the products can be enhanced, extending their service life. As the market continues to demand higher precision and efficiency from laminated products, the adhesive scraping device, as a core supporting equipment in the lamination process, directly affects the adhesion between the film and the substrate. Efficient adhesive scraping can effectively eliminate air bubbles between the lamination layers and ensure uniform distribution of the adhesive layer, while the subsequent film cutting process is related to the continuity and automation level of the production process.

[0003] Existing film coating adhesive scraping devices are widely used in metal sheet coating, cardboard coating, and other scenarios. They mainly consist of a scraper, scraper roller, cutting component, and conveying platform, all positioned behind the coating unit to form a continuous "coating-scraping-cutting" process. In use, the coating unit first applies adhesive film to the surface of substrates such as metal sheets and cardboard. The coated substrate then enters the scraper area via the conveying platform. The scraper applies uniform pressure to the film surface, while the scraper roller rolls and squeezes out interlayer air bubbles, enhancing the adhesion between the adhesive film and the substrate. After scraping, the device's built-in cutting component performs preliminary cutting of the adhesive film between multiple continuously conveyed substrates. To ensure stability during substrate transport and prevent substrate shifting after cutting, the cutting component typically does not completely sever the film, leaving uncut connecting segments on one or both sides. Once the substrate has been completely conveyed to the designated area, the remaining connecting segments are manually cut off by hand, completing the final separation.

[0004] Existing adhesive scraping devices rely on a preliminary cutting followed by manual finishing in actual use. The process of manually cutting off the residual film connection section by hand not only increases the labor intensity of operators but also easily leads to uneven cutting edges due to inconsistent force and angle of manual operation, affecting the appearance quality of the product. Moreover, in mass production scenarios, the lag of manual operation reduces overall production efficiency and increases time costs. Furthermore, there are safety hazards when using the cutting knife manually, as improper operation can easily cause hand cuts. At the same time, manual intervention makes it difficult to guarantee the uniformity of cutting accuracy. Therefore, there is an urgent need to improve the existing adhesive scraping devices for film coating. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a film coating adhesive scraping device to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a film coating adhesive scraping device, comprising a device body, a substrate on the device body, an adhesive coating on the substrate, and a first scraping component and a second scraping component corresponding to the substrate and the adhesive coating on the device body, and a first cutting component between the first scraping component and the second scraping component.

[0007] The device body is equipped with a mounting frame, and the bottom of the mounting frame is provided with a spring. A transmission frame is installed at the bottom of the spring. A pressing roller that is in contact with the adhesive film is rotatably mounted on the transmission frame, and a side cutter for cutting the adhesive film is installed at the bottom of the transmission frame.

[0008] By adopting the above technical solution, the double scraping glue component ensures firm adhesion, the pressure roller assists in leveling and venting, and the side cutting blade automatically cuts off the residual section, eliminating the need for manual recutting and improving efficiency and quality.

[0009] Furthermore, the device body is provided with multiple sets of drive rollers corresponding to the substrate, for conveying multiple sets of substrate movement.

[0010] By adopting the above technical solution, multiple sets of drive rollers can synchronously transport multiple sets of substrates, improving batch production efficiency and ensuring stable and non-deviation-prone transport.

[0011] Furthermore, multiple sets of the substrate are installed at equal intervals on the device body. The distance between the multiple sets of substrates is less than the diameter of the pressing roller, and the length of the pressing roller corresponds to the length of the portion of the adhesive-coated film cut by the first cutting component.

[0012] By adopting the above technical solution, the substrates are arranged at equal intervals to adapt to mass production, and the coverage of the pressing roller matches the cutting part, ensuring uniform pressing without any missed pressing.

[0013] Furthermore, a connecting bracket connected to the spring is slidably mounted on the mounting bracket, and multiple sets of bolts slidably connected to the mounting bracket are fixedly mounted on the top of the connecting bracket, and nuts that are in contact with the top surface of the mounting bracket are threaded onto the top of the bolts.

[0014] By adopting the above technical solution, the height of the connecting frame can be adjusted by bolts and nuts to adapt to substrates and coatings of different thicknesses, making the operation simple and the fixation stable.

[0015] Furthermore, multiple sets of telescopic rods connected to the transmission frame are installed at equal intervals at the bottom of the connecting frame, and the outer wall of each telescopic rod is fitted with a spring connected to the connecting frame and the transmission frame.

[0016] By adopting the above technical solution, the telescopic rod guides the transmission frame to rise and fall smoothly, and the spring provides uniform downward pressure, ensuring reliable edge pressing and cutting while preventing damage to the substrate.

[0017] Furthermore, two sets of the side cutters are symmetrically installed at the bottom of the transmission frame, and the side cutters are detachably connected to the bottom of the transmission frame.

[0018] By adopting the above technical solution, the dual-sided cutting blades achieve high synchronous cutting efficiency, and the detachable design facilitates replacement, adapting to diverse processing needs.

[0019] Furthermore, the plane at the bottom of the side cutter is higher than the plane at the bottom of the pressure roller, and the distance between the plane at the bottom of the side cutter and the plane at the bottom of the pressure roller is less than the length of the pressure roller sliding down, and the length of the side cutter is greater than the width of the uncut portion of the adhesive-coated film.

[0020] By adopting the above technical solution, the side cutting blade is at a reasonable height to prevent scratching the substrate, and its length is sufficient to cut the connecting section in one go, ensuring cutting accuracy and efficiency.

[0021] In summary, the present invention has the following main advantages:

[0022] This invention ensures a firm bond between the adhesive film and the substrate through the coordinated action of the first and second adhesive scraping components. After the first cutting component performs the initial cut, the pressure roller on the transmission frame adheres to the adhesive film to assist in air removal and leveling. Simultaneously, the side cutting blade cuts off the remaining connecting section, eliminating the need for manual recutting. This reduces labor intensity and safety hazards while ensuring smooth and uniform cutting edges. Furthermore, different second cutting components and side cutting blades can be replaced with bolts and nuts to adapt to different needs, improving film production efficiency and product quality.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] The embodiments of this utility model will be described below based on its overall structure.

[0031] A film coating adhesive scraper, such as Figure 1 - Figure 5 As shown, the device includes components such as the main body 1, the first adhesive scraping component 2, the second adhesive scraping component 3, the first cutting component 6, the mounting bracket 7, and the second cutting component;

[0032] The device body 1 serves as the mounting base for the entire adhesive scraping device, integrating various functional components. The device body 1 has a substrate 4 (such as a metal plate or cardboard) covered with an adhesive-coated film 5, which together constitute the core of the coating process. The device body 1 has a first adhesive scraping component 2 and a second adhesive scraping component 3 corresponding to the substrate 4 and the adhesive-coated film 5. The first adhesive scraping component 2 is used to initially smooth the adhesive layer of the adhesive-coated film 5 and remove some air bubbles, while the second adhesive scraping component 3 is used to further optimize the adhesive layer distribution, ensuring a tight fit between the adhesive-coated film 5 and the substrate 4. A first cutting component 6 is located between the first adhesive scraping component 2 and the second adhesive scraping component 3. The first cutting component 6 is used to initially cut the adhesive-coated film 5 between multiple sets of substrates 4 (retaining connecting sections on both sides or one side to prevent substrate 4 from shifting), preparing for subsequent complete separation.

[0033] Specifically, a mounting frame 7 is installed on the device body 1, which provides support and mounting carrier for the second cutting component; the second cutting component is the core functional component for cutting off the residual connecting section of the adhesive film 5. The second cutting component specifically includes a connecting frame 8, a telescopic rod 9, a transmission frame 10, a pressure roller 11, a spring 12, and a side cutting blade 13, which are used to complete the fine cutting of the adhesive film 5 and the complete separation of the substrate 4 after the initial cutting by the first cutting component 6;

[0034] The connecting frame 8 is slidably mounted on the mounting frame 7, serving as the upper connecting structure of the second cutting component. Multiple sets of bolts that are slidably connected to the mounting frame 7 are fixedly mounted on the top of the connecting frame 8. Nuts that are in contact with the top surface of the mounting frame 7 are threaded on the top of the bolts. The height of the connecting frame 8 can be adjusted by rotating the nuts, thereby synchronously adjusting the working position of the entire second cutting component to adapt to substrates 4 and adhesive-coated films 5 of different thicknesses. Multiple sets of telescopic rods 9 are evenly spaced at the bottom of the connecting frame 8. The bottom end of the telescopic rods 9 is connected to the transmission frame 10 to guide the transmission frame 10 to rise and fall in a straight line, preventing it from shifting or tilting under pressure.

[0035] Secondly, the transmission frame 10 is the intermediate transmission carrier of the second cutting component. Its top is connected to the telescopic rod 9 and the spring 12, and its bottom is used to install the edge pressing roller 11 and the side cutting blade 13. The edge pressing roller 11 is rotatably mounted on the transmission frame 10. The edge pressing roller 11 is in contact with the surface of the adhesive film 5 and rolls synchronously during the movement of the substrate 4. This can help to remove residual air bubbles between the adhesive film 5 and the substrate 4, and can also ensure that the adhesive film 5 is flat through continuous pressure, avoiding uneven cutting due to film wrinkles.

[0036] The outer wall of the telescopic rod 9 is fitted with springs 12. The two ends of the springs 12 are connected to the connecting frame 8 and the transmission frame 10 respectively. They are in a pre-compressed state, providing stable downward pressure to the transmission frame 10, ensuring that the pressing roller 11 always fits tightly against the adhesive film 5. At the same time, when the pressing roller 11 passes the spacing position of the substrate 4, it pushes the transmission frame 10 down through the elastic force, ensuring that the side cutting blade 13 can accurately contact and cut off the residual connecting section.

[0037] In this embodiment, two sets of side-cutting blades 13 are symmetrically installed at the bottom of the transmission frame 10 to simultaneously cut the residual connecting segments on both sides of the adhesive-coated film 5, thereby improving cutting efficiency. The side-cutting blades 13 are detachably connected to the bottom of the transmission frame 10, making it easy to replace the side-cutting blades 13 with different blade types according to the thickness and material of the adhesive-coated film 5. The plane at the bottom of the side-cutting blade 13 is higher than the plane at the bottom of the pressure roller 11, and the distance between the two is less than the length of the pressure roller 11 sliding down. This allows for precise application to the residual connecting segments of the adhesive-coated film 5 while avoiding direct contact between the blade and the substrate 4, which could cause scratches. The length of the side-cutting blade 13 is greater than the width of the uncut portion of the adhesive-coated film 5, ensuring that the entire residual connecting segment is cut off in one go without repeated operation.

[0038] For example, the device body 1 is provided with multiple sets of drive rollers corresponding to the substrate 4, which are used to transport multiple sets of substrates 4 arranged at equal intervals to move synchronously; at the same time, the distance between the multiple sets of substrates 4 is less than the diameter of the pressing roller 11, and the length of the pressing roller 11 corresponds to the length of the part of the adhesive film 5 cut by the first cutting component 6, so as to ensure that the pressing roller 11 can fully cover the processing area of ​​the adhesive film 5 and ensure the uniformity of the pressing and cutting effect.

[0039] Through the coordinated operation of the above components, during use, the drive roller moves the substrate 4 and the adhesive film 5, sequentially passing through the first adhesive scraping component 2 for initial adhesive scraping, the second adhesive scraping component 3 for fine adhesive scraping, and the first cutting component 6 for initial cutting; then the edge pressing roller 11 in the second cutting component adheres to the adhesive film 5 to assist in flattening, and the spring 12 pushes the side cutting blade 13 through the transmission frame 10 to cut off the remaining connecting section; if it is necessary to adjust the cutting pressure or height, the position of the connecting frame 8 can be adjusted by rotating the nut on the connecting frame 8, or the appropriate second cutting component can be directly replaced.

[0040] The working principle of this utility model is as follows: After the device is started, multiple sets of drive rollers on the device body 1 are started, which drive multiple sets of substrates 4, such as metal plates and cardboard, arranged at equal intervals to move synchronously. The adhesive film 5 pre-covered on the surface of the substrate 4 will enter the adhesive scraping area along with the substrate 4.

[0041] The substrate 4 and the adhesive-coated film 5 first pass through the first adhesive scraping component 2. The first adhesive scraping component 2 applies pressure to the surface of the adhesive-coated film 5, initially smoothing the adhesive layer and removing some interlayer air bubbles. Then it enters the second adhesive scraping component 3. The second adhesive scraping component 3 further optimizes the adhesive layer distribution, ensuring that the adhesive-coated film 5 and the substrate 4 are tightly bonded, improving the adhesion strength, and laying the foundation for the subsequent cutting process.

[0042] After being processed by the first scraping component 2, the substrate 4 and the adhesive-coated film 5 continue to move to the bottom of the first cutting component 6. The first cutting component 6 cuts the adhesive-coated film 5 between multiple sets of substrates 4. In order to ensure the stability of the substrate 4 during the conveying process and to avoid displacement after cutting, the connecting section on both sides or one side of the adhesive-coated film 5 will be retained during cutting, and it will not be completely cut off, so as to achieve initial separation.

[0043] After the initial cutting, the substrate 4 continues to move to the bottom of the mounting frame 7. At this time, the two sets of side cutters 13 symmetrically installed at the bottom of the transmission frame 10 will perform a secondary cut on the remaining connecting section of the adhesive film 5. Since the plane at the bottom of the side cutter 13 is higher than the plane at the bottom of the pressure roller 11, and the distance between the two is less than the sliding length of the pressure roller 11, it can accurately contact and cut the remaining connecting section, while avoiding scratching the substrate 4. At the same time, the length of the side cutter 13 is greater than the width of the uncut part of the adhesive film 5, so the entire remaining connecting section can be cut off at once without repeated operation, achieving complete separation of the substrate 4 and the adhesive film 5.

[0044] Throughout the process, the pressure roller 11 and the transmission assembly work together to ensure the cutting and adhesive scraping effects. The pressure roller 11, which is rotatably mounted on the transmission frame 10, is in contact with the surface of the adhesive-coated film 5. Because the spring 12 at the bottom of the mounting frame 7 is sleeved on the outer wall of the telescopic rod 9, and the telescopic rod 9 connects the connecting frame 8 and the transmission frame 10, and the spring 12 is in a compressed state, the spring 12 pushes the transmission frame 10 through its elastic force, so that the pressure roller 11 is always in close contact with the adhesive-coated film 5. When the pressure roller 11 rolls, it can not only help to remove residual air bubbles, but also ensure that the adhesive-coated film 5 is flat through pressure, avoiding uneven cutting due to film wrinkles during cutting. When the distance between the pressure roller 11 and the substrate 4 corresponds, the spring 12 will push the transmission frame 10 downward through its elastic force, driving the side cutter 13 to move downward, ensuring that the side cutter 13 can smoothly cut the adhesive-coated film 5.

[0045] If it is necessary to adjust the pressing force or the height of the side cutter 13, the nut on the top of the connecting frame 8 is rotated to release the nut's restriction on the bolt. Then, the connecting frame 8 is pulled off the mounting frame 7 and replaced with a different model of the second cutting component. The second cutting component includes the connecting frame 8, the telescopic rod 9, the transmission frame 10, the pressing roller 11, the spring 12, and the side cutter 13. At the same time, the side cutter 13 is detachably connected to the bottom of the transmission frame 10, which makes it easy to replace different models of the side cutter 13 as needed.

[0046] This device achieves automated glue scraping and cutting of film coating through precise linkage of mechanical structures, which not only improves product quality and production efficiency, but also reduces manual labor intensity and safety hazards. It is suitable for mass film coating production scenarios in industries such as metal processing and packaging printing.
