Description

Technical Field

[0001] This application relates to the field of aluminum profile film application technology, and in particular to a multi-sided aluminum profile film application device. Background Technology

[0002] Aluminum profiles, as a lightweight and high-strength material, are widely used in construction, manufacturing, packaging and other fields. During processing, transportation and use, aluminum profiles need to be protected with a film to effectively avoid scratches, contamination or oxidation that could affect the surface quality of the aluminum profiles.

[0003] In existing technology, aluminum profile film application devices typically include a machine body, a conveyor belt, a limiting wheel, and a film application wheel. The machine body has an inlet end and an outlet end at both ends, and the conveyor belt, limiting wheel, and film application wheel are all mounted on the machine body. When applying film to aluminum profiles, the aluminum profile with a rectangular cross-section is first placed on the conveyor belt. After entering the inlet end via the conveyor belt, the limiting wheel limits the position of the aluminum profile. Then, the film application wheel is driven to rotate and apply the protective film to the upper surface of the aluminum profile. After the aluminum profile reaches the outlet end via the conveyor belt, the aluminum profile is moved back to the inlet end to apply film to the other side of the aluminum profile. The above process is repeated to achieve the film application process on all four side walls of the aluminum profile.

[0004] Regarding the aforementioned technologies, existing aluminum profile film application devices are mainly suitable for applying films to aluminum profiles with rectangular cross-sections, but are not suitable for aluminum profiles with approximately triangular cross-sections, indicating that the applicability of aluminum profile surface film application devices is not high. Summary of the Invention

[0005] To improve the applicability of film application to different aluminum profiles, this application provides a multi-sided film application device for aluminum profiles.

[0006] The multi-sided film application device for aluminum profiles provided in this application adopts the following technical solution:

[0007] A multi-sided film application device for aluminum profiles includes a frame, a film application mechanism, and a conveying mechanism. The frame is horizontally arranged, and both the film application mechanism and the conveying mechanism are mounted on the frame. One end of the frame is provided with a feeding end, and the other end is provided with a discharging end.

[0008] The film application mechanism includes a film application assembly, and the film application assembly includes at least one set of transverse film application components;

[0009] Each set of the transverse film-applying components includes a support base, a connecting rod, a first limiting wheel, a first film-applying wheel, two support columns, and a first driving component. The support base is horizontally mounted on the frame. The support columns include a first support column and a second support column mounted on the support base. The first support column and the second support column are located on both sides of the conveying mechanism. The first support column is slidably mounted on the support base and slides away from or towards the second support column.

[0010] The first limiting wheel is located between the two support columns. The first driving member is mounted on the second support column. One end of the first limiting wheel is hinged to the power output end of the first driving member. The first driving member drives one end of the first limiting wheel to move in the vertical direction. The other end of the first limiting wheel is hinged to the second support column. The first film-applying wheel is connected to the first limiting wheel through the connecting rod. The axial direction of the first film-applying wheel is parallel to the axial direction of the first limiting wheel. The length of the first film-applying wheel is less than the length of the first limiting wheel.

[0011] By adopting the above technical solution, after the aluminum profile is conveyed to the feeding end of the frame by the conveying mechanism, the position of the aluminum profile to be coated is first limited by the limiting component to ensure its accurate delivery to the coating mechanism. After the aluminum profile reaches the position of the coating component, according to the included angle or specifications of two adjacent faces of the rectangular or approximately triangular aluminum profile, the first driving component is adjusted to drive the first limiting wheel to move along the height direction of the second support column near the end of the second support column. At the same time, the first limiting wheel drives the first support column to slide away from or towards the second support column until the side of the first limiting wheel... After the film is applied to the aluminum profile, the aluminum profile drives the first film-applying wheel to rotate and apply the film to the aluminum profile. By adjusting the first driving component, the first limiting wheel is driven to move, and then the first support column is driven to slide so that the first limiting wheel is applied to the surface of the aluminum profile with an approximately triangular or rectangular cross-section. The first film-applying wheel then completes the application of the film to the aluminum profile. This method is convenient for applying film to aluminum profiles with approximately triangular or rectangular cross-sections where two adjacent surfaces have different included angles, thereby improving the applicability of film application to different aluminum profile surfaces.

[0012] Preferably, the transverse film-applying component is provided in two sets. A second driving component is installed on the first support column. The end of the first limiting wheel away from the second support column is hinged to the power output end of the second driving component. The second driving component drives one end of the first limiting wheel to move in the vertical direction.

[0013] By adopting the above technical solution, and simultaneously adjusting the first driving component and the second driving component to drive the first limiting wheel to move along the length direction of the support column, it is convenient to realize the film application process for aluminum profiles with rectangular cross-sections of different sizes and specifications, which is beneficial to improving the applicability of film application to the surface of aluminum profiles with rectangular cross-sections of different sizes and specifications.

[0014] Preferably, both the first driving component and the second driving component include a cylinder and a connecting block. The first support column and the second support column are hollow. Sliding holes are also provided on the side walls of the two support columns. The sliding holes are distributed along the length direction of the support column. The cylinder is located in the inner cavity of the support column. The connecting block is fixedly connected to the end of the piston rod of the cylinder. The two ends of the first limiting wheel are respectively hinged to the two connecting blocks.

[0015] By adopting the above technical solution, the movement of the cylinder is adjusted, and the piston rod of the cylinder drives the connecting block to move along the length of the support column. The connecting block drives the first limit wheel to move along the length of the sliding hole, which facilitates the rapid adjustment of the height of the first limit wheel.

[0016] Preferably, the film-applying assembly further includes a longitudinal film-applying component, which includes two vertically arranged second film-applying wheels. The second film-applying wheels are rotatably connected to the frame and are symmetrically distributed on both sides of the conveying mechanism.

[0017] By adopting the above technical solution, it is easy to simultaneously apply film to the two opposite sidewalls of a rectangular aluminum profile near the second film-applying wheel, thereby improving the film-applying efficiency on the aluminum profile surface.

[0018] Preferably, the film-applying mechanism further includes at least three sets of limiting components, which are sequentially distributed at the feed end, discharge end, and side of the frame near the film-applying component.

[0019] By adopting the above technical solution, the three sets of limiting components can effectively limit the position of the aluminum profile, and to a certain extent prevent the aluminum profile from slipping during the conveying process, causing the film-applying roller to misalign with the film-applying surface of the aluminum profile, thereby improving the film-applying effect on the surface of the aluminum profile.

[0020] Preferably, the limiting component includes a mounting base, a third driving member, and two second limiting wheels. The mounting base is mounted on the frame, the second limiting wheels are axially perpendicular to the mounting base, and the two second limiting wheels are symmetrically distributed on both sides of the conveying mechanism. The third driving member is mounted on the mounting base, and the third driving member drives the second limiting wheels to move closer to or further away from each other.

[0021] By adopting the above technical solution, it is convenient to drive the two second limit wheels away from each other or closer together by adjusting the third driving component, thereby realizing the lateral limit of aluminum profiles of different sizes and specifications, and improving the applicability of film to the surface of aluminum profiles of different sizes and specifications.

[0022] Preferably, the third driving component includes a set of sliders and a bidirectional lead screw. The bidirectional lead screw is located in the mounting base and is arranged perpendicular to the conveying direction of the conveying mechanism. The mounting base is also provided with a sliding groove, which is distributed along the axial direction of the bidirectional lead screw. A set of sliders is installed on the threaded sections on both sides of the bidirectional lead screw, and the sliders are slidably installed in the sliding grooves. Each slider is fixedly connected to a second limiting wheel.

[0023] By adopting the above technical solution, the bidirectional lead screw is driven to rotate, causing the two sliders installed on the bidirectional lead screw to move away from or towards each other, thereby driving the two second limit wheels to move away from or towards each other. This facilitates the rapid realization of the limiting process for aluminum profiles of different sizes and specifications, thereby improving the film application efficiency for aluminum profiles of different sizes and specifications.

[0024] Preferably, it further includes a clamping mechanism, which includes a first clamping component and at least three sets of second clamping components, wherein the first clamping component and the second clamping components are arranged sequentially close to one side of the mounting base.

[0025] By adopting the above technical solution, the first pressing component and the second pressing component facilitate full contact between the protective film and the surface of the aluminum profile, to a certain extent ensure that the air between the protective film and the surface of the aluminum profile is discharged, and prevent creases from appearing in the protective film during the bonding process, ensuring the flatness of the film and further protecting the surface of the aluminum profile.

[0026] Preferably, the first clamping assembly includes a mounting frame and a plurality of first clamping rollers. The mounting frame is vertically arranged, and a plurality of mounting grooves are provided on one side wall of the mounting frame. The mounting grooves are arranged perpendicular to the conveying direction of the conveying mechanism. One end of each of the plurality of first clamping rollers is located in the mounting groove and moves away from or close to the aluminum profile along the length of the mounting groove.

[0027] By adopting the above technical solution, multiple first pressing rollers are adjusted to move away from or closer to the surface of the aluminum profile along the length of the mounting groove, which facilitates the pressing of the protective film on the upper surface of aluminum profiles with rectangular cross-sections of different sizes and specifications, thereby improving the film application effect on aluminum profiles with rectangular cross-sections of different sizes and specifications.

[0028] Preferably, the second clamping assembly includes a lead screw, a connecting block, a pressure plate, two mounting plates, and a second clamping wheel. The two mounting plates are positioned opposite each other on the frame. The lead screw is rotatably connected to the frame and is positioned perpendicular to the conveying direction of the conveying mechanism. The connecting block is mounted on the lead screw and is positioned along the length of the lead screw away from or near the aluminum profile. The pressure plate is located between the two mounting plates. One end of the second clamping wheel is hinged to the connecting block, and the other end is hinged to the pressure plate. A sliding groove is also provided on the mounting plate. The sliding groove is vertically positioned, and sliding blocks are fixedly connected to the two side walls of the pressure plate opposite to the sliding groove. The sliding blocks are located in the sliding groove and slide along the length of the sliding groove. The height of the mounting plate is greater than the height of the second clamping wheel when it is in a vertical position.

[0029] By adopting the above technical solution, the lead screw is driven to rotate, which in turn causes the connecting block mounted on the lead screw to move away from or towards the aluminum profile. This, in turn, causes the second pressing wheel to move away from or towards the aluminum profile, facilitating the pressing of the protective film onto the surface of the aluminum profile with two adjacent faces having different included angles. This improves the film application effect on the aluminum profile with two adjacent faces having different included angles. In addition, the height of the mounting plate is greater than the height of the second pressing wheel when it is in a vertical position, which can prevent the pressure plate from sliding out of the mounting plate along the length of the slide groove when the included angle between two adjacent faces of the aluminum profile is small, thus affecting the pressing effect of the film on the surface of the aluminum profile.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. The aluminum profile multi-sided film application device is configured to adjust the first driving component to drive the first limiting wheel to move, and then drive the first support column to slide so that the first limiting wheel is in contact with the surface of the aluminum profile with an approximately triangular cross section or a rectangular cross section. The film application is completed by rotating the first film application wheel. This method is convenient for applying film to aluminum profiles with approximately triangular cross sections and rectangular cross sections with two adjacent surfaces having different included angles, thereby improving the applicability of film application to different aluminum profile surfaces.

[0032] 2. The setting of the limiting component makes it easy to limit the position of the aluminum profile, which to a certain extent prevents the aluminum profile from slipping during the conveying process, causing the film-applying roller to misalign with the film-to-be-applied surface of the aluminum profile, thereby improving the film-applying effect on the surface of the aluminum profile.

[0033] 3. The second clamping component facilitates the clamping of the protective film onto the surface of an aluminum profile with an approximately triangular cross-section and two adjacent surfaces at different angles, thereby improving the film application effect on the aluminum profile with an approximately triangular cross-section and two adjacent surfaces at different angles.

To prevent the first film-applying wheel 224 from being too long, causing the first limiting wheel 223 to be in an inclined state after being adjusted by the first driving member 226, the second driving member 228, and the sliding member 229, the end of the first film-applying wheel 224 away from the first support column 2251 abuts against the second support column 2252, making it impossible to adjust the inclination angle of the first limiting wheel 223. In this application, the length of the first film-applying wheel 224 is less than the length of the first limiting wheel 223.

[0050] Reference Figure 1 and Figure 2The pressing mechanism 4 includes a first pressing component 41 and at least three sets of second pressing components 42, and the first pressing component 41 and the second pressing component 42 are arranged sequentially close to one side of the film application mechanism 2;

In addition, in this application, the height of the mounting plate 424 is greater than the height of the second pressing wheel 425 when it is in the vertical state.

[0054] The implementation principle of the aluminum profile multi-sided film application device in this application embodiment is as follows: When applying film to an aluminum profile with a rectangular cross-section, firstly, after installing the protective film on the first film application wheel 224, the aluminum profile is conveyed to the feeding end of the frame 1 by the conveying mechanism 3. Then, the third driving component 242 is adjusted to drive the second limiting wheel 243 to move away from or closer to each other to limit the position of the aluminum profile, so that it enters the film application mechanism 2 along the limited channel. Then, the first driving component 226 and the second driving component 228 are adjusted simultaneously to keep the first limiting wheel 223 axially horizontal. The mechanism is raised and lowered, which in turn drives the first film-applying roller 224 to rise and lower, thereby limiting the film application on aluminum profiles with rectangular cross-sections of different sizes and specifications. The first film-applying roller 224 completes the film application process on the upper and lower surfaces of the aluminum profile. At the same time, the longitudinal film-applying component 23 is adjusted to complete the film application process on the other two opposite surfaces of the aluminum profile. Finally, after the aluminum profile with film application is completed enters the pressing mechanism 4, the fourth driving component 414 is adjusted to drive the first pressing roller 412 to rise and lower, thereby pressing the protective film on the aluminum profiles with rectangular cross-sections of different sizes and specifications against the aluminum profile.

[0055] When processing aluminum profiles with an approximately triangular cross-section, firstly, the longitudinal film-applying component 23 and the first pressing roller 412 are adjusted to ensure they do not interfere with the transport of the profile. Then, after the aluminum profile is conveyed by the conveying mechanism 3 to the feeding end of the frame 1, the third driving component 242 is adjusted to drive the second limiting roller 243 to move away from or closer to each other to limit the position of the aluminum profile, allowing it to enter the film-applying mechanism 2 along the limited channel. Then, the first driving component 226 is adjusted to drive the first limiting roller 223 to rise and fall near the end of the second support column 2252, and the sliding component 229 drives the first support column 2251 to move away from or closer to the second support column. 2252 moves to one side, causing the first limiting wheel 223 to tilt and fit against the side wall of the aluminum profile. The two symmetrically arranged first limiting components 24 further limit the aluminum profile with an approximately triangular cross section. Then, the first limiting wheel 223 performs the film application process on the two side walls of the aluminum profile with an approximately triangular cross section. Finally, after the aluminum profile with the film is applied, it enters the pressing mechanism 4. The drive screw 421 drives the first pressing wheel 412 to fit against the side wall of the aluminum profile, thereby pressing the protective film on aluminum profiles with approximately triangular cross sections of different sizes and specifications against the aluminum profile.
