Description

Technical Field

[0001] This utility model relates to the field of profile processing equipment technology, specifically to a profile film application device. Background Technology

[0002] Aluminum profiles are alloy materials with aluminum as the main component, manufactured into profile products with different cross-sectional shapes and sizes through processes such as hot melting and extrusion. They are widely used in modern industry and offer numerous significant advantages. In terms of processing performance, aluminum profiles are highly malleable, easily formed into various complex shapes and structures of parts through cutting, drilling, bending, and other processing methods, meeting the design requirements of different products. Furthermore, their surface treatment technology is mature; after treatments such as anodizing, electrophoretic coating, and powder coating, not only is the corrosion resistance of aluminum profiles enhanced, extending their service life, but they also achieve a rich variety of colors and glosses, improving the aesthetics of the products. Despite the many advantages of aluminum profiles, their surfaces are highly susceptible to scratches, wear, and corrosion during production, transportation, and processing, thus affecting the quality and aesthetics of the products. Therefore, applying a protective film to aluminum profiles is particularly necessary.

[0003] A Chinese utility model patent with publication number CN213353540U discloses an aluminum profile film applicator. Specifically, the operator first places the protective film roll onto the roller and then places the aluminum profile on multiple rotating rollers. Next, two moving plates are moved so that the limiting rollers on the moving plates are in contact with the side of the aluminum profile. Then, the clamping rod is rotated to lock it into the corresponding position on the clamping strip, thus fixing the moving plates. The protective film is then pulled out and applied to the upper surface of the right side of the aluminum profile. The motor is then started to move the aluminum profile to apply the film. After the film application is completed, the electric telescopic rod is started to drive the cutting blade down into the cutting block to cut the protective film.

[0004] However, in the above technical solution, the film application process involves first applying film to the upper surface of the profile, but the lower surface of the profile may be scratched due to friction when it moves on multiple rotating rollers. These scratches will damage the original surface quality of the profile, affect its aesthetics and subsequent processing effects, thereby shortening the service life of the profile.

[0030] like Figures 1-6As shown, a profile film-applying device according to one embodiment of the present invention includes a conveying mechanism 1, a film-applying mechanism 2, and a film-cutting mechanism 3. The conveying mechanism 1 includes several rotating rollers 11. The film-applying mechanism 2 is fixedly connected to the conveying mechanism 1 and is disposed below each rotating roller 11. The film-cutting mechanism 3 is fixedly connected to the film-applying mechanism 2. The film-applying mechanism 2 includes a fixing frame 21, a film-laying structure 22, and a film-pressing structure 23. The film-laying structure 22 and the film-pressing structure 23 are respectively fixedly connected to the fixing frame 21. A protective film roll 4 is sleeved on the film-laying structure 22. The protective film roll 4 is pulled out, passes over the top of the film-pressing structure 23, and is placed above the first rotating roller 11. The lower surface of the profile comes into contact with the protective film roll 4, and the lower surface of the profile is first adhered. The film-cutting mechanism 3 is fixedly connected to the end of the fixing frame 21 near the film-pressing structure 23. By setting the conveying mechanism 1, the rollers can stably support and convey the profile, ensuring that the profile maintains linear movement during the film-applying process, thereby improving the film-applying quality. By setting up the film-applying mechanism 2, and utilizing the collaborative work of the film-laying structure 22 and the film-pressing structure 23, the protective film can be precisely applied to the lower surface of the profile. The film-laying structure 22 ensures the stable release of the protective film roll 4, while the film-pressing structure 23 tightly adheres the protective film to the lower surface of the profile. By setting up the film-cutting mechanism 3, manual operation is reduced, production efficiency is improved, and labor intensity is reduced. In this embodiment, the conveying mechanism 1 adopts an existing conveyor with rotating rollers 11, which will not be described in detail here.

[0031] As a preferred embodiment of this utility model, it may also have the following additional technical features: the film-laying structure 22 includes a drive motor 221, a rotating shaft 222, a first fixed seat 223, and a second fixed seat 224.

By precisely controlling the rotation of the rotating shaft 222 through the drive motor 221, it can be ensured that the protective film roll 4 can be laid out smoothly and continuously, ensuring the film-laying quality of the profile.

[0032] As a preferred embodiment of this utility model, it may also have the following additional technical features: the film pressing structure 23 includes a first mounting plate 231, a first telescopic structure 232, a first mounting base 233, a first rotating shaft 234, and a heating roller 235. The first telescopic structure 232 is fixedly connected to the first mounting plate 231, one end of the first telescopic structure 232 passes through the first mounting plate 231, and the end of the first telescopic structure 232 away from the first mounting plate 231 is fixedly connected to the first mounting base 233. The first rotating shaft 234 is rotatably connected to the first mounting base 233. The heating roller 235 is sleeved on the first rotating shaft 234, and a heating element 2351 is disposed inside the heating roller 235. Through the first telescopic structure 232, the film pressing structure 23 can adaptively adjust according to the thickness, weight, and film application requirements of the profile, providing a stable film pressing force. When the thickness of the profile changes, the first telescopic structure 232 can extend and retract, ensuring that the heating roller 235 always maintains appropriate contact pressure with the surface of the profile, thereby ensuring the quality of film application. During the film application process, the heating roller 235 heats the protective film, making it softer and easier to adhere to the profile surface. Simultaneously, the rotation of the heating roller 235 ensures the protective film spreads evenly across the profile surface, preventing issues such as bubbles and wrinkles, thereby improving the aesthetics and consistency of the applied film.

[0033] As a preferred embodiment of this utility model, it may also have the following additional technical features: the first telescopic structure 232 includes a first connecting plate 2321, a first connecting rod 2322, a first fixing sleeve 2323 and a first elastic element 2324. The first connecting plate 2321 is fixedly connected to the first mounting base 233, the first fixing sleeve 2323 is fixedly connected to the first mounting plate 231, one end of the first connecting rod 2322 is fixedly connected to the first connecting plate 2321, and the end of the first connecting rod 2322 away from the first connecting plate 2321 passes through the first fixing sleeve 2323 and the first mounting plate 231 in sequence. The first elastic element 2324 is sleeved on the first connecting rod 2322, one end of the first elastic element 2324 is fixedly connected to the first connecting plate 2321, and the end of the first elastic element 2324 away from the first connecting plate 2321 is fixedly connected to the first fixing sleeve 2323. The first elastic element 2324 is sleeved on the first connecting rod 2322. When the thickness of the profile changes or minor unevenness is encountered during the film application process, the first elastic element 2324 can deform, thereby buffering and absorbing the impact force caused by these changes. In this embodiment, the first elastic element 2324 is set as a spring. In addition, in other embodiments, by adjusting the elastic coefficient or pre-compression amount of the first elastic element 2324, the magnitude of the film pressing force can be precisely controlled, so that the film pressing structure 23 can adapt to the film application requirements of profiles with different thicknesses and materials, thereby improving the stability and consistency of the film application quality.

[0034] As a preferred embodiment of this utility model, it may also have the following additional technical features: including a dust-adhesive structure 5, which is fixedly connected to the end of the fixing frame 21 away from the film-cutting mechanism 3. It can effectively remove dust and fine particles from the lower surface of the profile before the profile enters the film-applying mechanism 2, reduce the scratches caused by these impurities on the lower surface of the profile when they move on the rotating roller 11, and effectively ensure the film-applying effect.

[0035] As a preferred embodiment of this utility model, it may also have the following additional technical features: the dust-adhesive structure 5 includes a second mounting plate 51, a second telescopic structure 52, a second mounting base 53, a second rotating shaft 54, and a dust-adhesive roller 55.

The second rotating shaft 54 ​​is rotatably connected to the second mounting base 53. The dust-adhesive roller 55 is sleeved on the second rotating shaft 54, and an adhesive layer is connected to the outer surface of the dust-adhesive roller 55. When the profile passes through the dust-adhesive roller 55, the adhesive layer can effectively adsorb dust, particles, and other impurities on the surface of the profile. In this embodiment, the adhesive layer is set as a self-adhesive coating.

[0036] As a preferred embodiment of this utility model, it may also have the following additional technical features: the second telescopic structure 52 includes a second connecting plate 521, a second connecting rod 522, a second fixing sleeve 523, and a second elastic member 524.

This buffering effect ensures that the sticky roller 55 maintains appropriate contact pressure with the profile surface, ensuring consistent sticking effect. In this embodiment, the second elastic element 524 is a spring. Furthermore, in other embodiments, the contact pressure between the sticky roller 55 and the profile surface can be precisely controlled by adjusting the elastic coefficient or pre-compression amount of the second elastic element 524.

[0037] As a preferred embodiment of this utility model, it may also have the following additional technical features: the film cutting mechanism 3 includes a fixed plate 31, a translation structure 32, and a cutting structure 33. The fixed plate 31 is fixedly connected to the fixed frame 21, the translation structure 32 is fixedly connected to the fixed plate 31, and the cutting structure 33 is fixedly connected to the translation structure 32. In this embodiment, by adjusting the movement range of the translation structure 32, it can adapt to the cutting requirements of protective films of different widths, thus enhancing the versatility of the film cutting mechanism 3.

[0038] As a preferred embodiment of this utility model, it may also have the following additional technical features: the translation structure 32 includes a translation motor 321, a main rotating wheel 322, an auxiliary rotating wheel 323 and a belt 324.

The sliding seat 331 is fixedly connected to the belt 324, and a receiving groove 3311 is provided on the sliding seat 331. The cutting blade 332 is disposed in the receiving groove 3311. The stable movement of the sliding seat 331 and the sharp design of the cutting blade 332 together ensure that the cutting structure 33 can accurately cut according to a predetermined trajectory, improving cutting accuracy and film application quality. When the cutting blade 332 is worn or damaged, it can be easily removed from the receiving groove 3311 of the sliding seat 331 and replaced.

[0040] The working principle of the profile film application device in this embodiment is as follows: First, before the profile enters the film application mechanism 2, the dust-adhesive structure 5 starts working. The adhesive layer on the dust-adhesive roller 55 effectively adsorbs dust, particles, and other impurities on the lower surface of the profile. Then, the drive motor 221 in the film-laying structure 22 precisely controls the rotation of the rotating shaft 222, so that the protective film roll 4 smoothly and continuously releases the protective film. After the operator pulls out the protective film, it passes over the top of the pressing structure 23 and is placed above the first rotating roller 11, ready to contact the lower surface of the profile. Before the profile enters the film application area, the starting end of the profile is initially adhered to the protective film manually to ensure that the two are tightly adhered. After the starting end of the profile is adhered to the protective film, the profile continues to be conveyed forward, and its lower surface contacts the protective film. The heating roller 235 in the pressing structure 23 heats the protective film under the action of the heating element 2351, making it soft and easier to adhere to the profile surface. After the profile film application is completed, the film cutting mechanism 3 starts working. The translation motor 321 in the translation structure 32 drives the main rotating wheel 322 and the auxiliary rotating wheel 323 to rotate, and drives the cutting structure 33 to move to the position to be cut via the belt 324.

[0041] The profile film application device in this embodiment has a reasonable structural design and is easy to use. This structure can also be used for other devices with similar usage requirements. In this embodiment, the profile film application device can first apply film to the lower surface of the profile to reduce scratches and wear on the lower surface of the profile, protect the original surface quality of the profile, and thus extend the service life of the profile.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
