Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection.

[0036] In the description of the embodiments, it should be understood that terms such as "up", "down", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the embodiments and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on the embodiments.

[0037] Existing laminating equipment is usually used for laminating aluminum profiles of conventional shapes such as rectangles, but cannot be used for laminating aluminum profiles with special shapes such as curved surfaces. At the same time, after the existing equipment completes the laminating operation of an aluminum profile and cuts off the protective film, the protective film needs to be manually attached to the next aluminum profile, which affects production efficiency and is prone to safety accidents during operation.

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 8 , Fig. 9 and Fig.10 As shown, an embodiment of the present invention provides an aluminum profile coating device, including a conveying frame 1, an adjustable pressing device 2, a pneumatic traction device 3, a center positioning device 4 and a height limiting device 5, and a mounting plate 6 is fixedly arranged on the conveying frame 1, and the mounting plate 6 is arranged above the conveying frame 1.

[0039] Among them, the center positioning device 4 and the height limiting device 5 are respectively fixedly arranged on the conveying platform 1. The center positioning device 4 is used for the lateral center positioning of the aluminum profile. By clamping the aluminum profile laterally, the lateral position of the aluminum profile can be guaranteed to be fixed to avoid movement during the coating process. At the same time, the lateral center positioning of aluminum profiles of various specifications can be achieved. The height limiting device 5 is used for the vertical position positioning of the aluminum profile to avoid vertical movement during the coating process and improve the stability of the coating. At the same time, since the height of the height limiting device 5 is adjustable, the vertical positioning of aluminum profiles of different heights can be achieved.

[0040] The pneumatic traction device 3 is arranged on the mounting plate 6. After the coating of an aluminum profile is completed, the protective film can be fixed by negative pressure adsorption. The auxiliary cutting device 54 cuts off the protective film, and then the cut end of the protective film can be pulled and pressed onto the next aluminum profile to be coated to realize automatic replacement of parts and film pasting. The pneumatic traction device 3 includes a traction box 7, which is used for traction and fixation of the protective film. When the protective film is negatively fixed, the inclination angle of the traction box 7 can be adjusted to improve the fixing effect. The negative pressure adsorption fixation method is not only fast and effective, but also can avoid damage to the protective film during the fixing process.

[0041] The adjustable pressing device 2 is arranged on the mounting plate 6, which can further press the protective film attached to the surface of the aluminum profile onto the surface of the aluminum profile, thereby improving the bonding strength and avoiding the generation of bubbles during the bonding process. At the same time, it can be adaptively adjusted according to the shape of the surface of the aluminum profile to be filmed, so as to realize the lamination operation of aluminum profiles of various shapes, including a height adjustment device 8 and a flexible extrusion device 9. The height adjustment device 8 is fixedly arranged on the mounting plate 6, and is used for adjusting the height of the flexible extrusion device 9, so that the flexible extrusion device 9 is pressed onto the aluminum profile while ensuring the appropriate pressing force. The flexible extrusion device 9 is movably arranged on the height adjustment device 8, and is used for pressing the protective film onto the aluminum profile.

The power output shaft of the driving motor 21 is connected to a group of driving rollers 19 by power. The adjusting rod 12 pushes the flexible extrusion device 9 to descend as a whole through the extrusion spring 18. Due to the setting of the extrusion spring 18, it can be ensured that the flexible extrusion device 9 can be pressed on the aluminum profile with a certain pressure. The tensioning mechanism 15 is provided with multiple groups, and the multiple groups of tensioning mechanisms 15 have the same structure. The multiple groups of tensioning mechanisms 15 are respectively movably arranged on the top plate of the fixed frame 14.

[0046] The driving motor 21 drives the extrusion belt 34 to rotate through the driving roller 19.

When the extrusion belt 34 fits on the curved surface, under the action of the extrusion force, the extrusion frame 28 overcomes the deflection of the second return spring 29, thereby driving the extrusion belt 34 to deflect, so that the extrusion belt 34 can fit more closely. At the same time, the fine-tuning slider 31 overcomes the elastic force of the third return spring 32 under the action of the extrusion force and slides upward, so that the extrusion ball 30 on the extrusion frame 28 is pressed tightly on the extrusion belt 34, and the extrusion belt 34 is deformed to a certain extent, further making the extrusion belt 34 fit on the aluminum profile for lamination.
