Aluminum foil. Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the figures, the thickness of parts may be exaggerated or reduced for the purpose of effectively depicting the technical content.

[0025] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0026] At least one embodiment provides an aluminum-plastic film production line, such as Figure 1 As shown, it includes: a conveying mechanism 1, a coating mechanism 2, and a suspended drying oven 3.

[0027] Specifically, the conveying mechanism 1 includes several conveying rollers 11 for conveying aluminum foil 5.

[0028] Specifically, the coating mechanism 2 includes a gravure roller 21 for applying adhesive to the lower surface of the conveyed aluminum foil 5.

[0029] Specifically, the suspended oven 3 is located downstream of the coating mechanism 2 and is used to heat-dry the adhesive on the lower surface of the aluminum foil 5 with hot air, thereby making the adhesive quickly generate strong adhesion.

[0030] Since the suspended oven 3 treats the adhesive on the aluminum foil 5 with hot air, the aluminum foil 5 will be vibrated. This vibration will be transmitted to the upstream gravure roller 21, resulting in slight scratches.

[0031] To address the above problems, in some embodiments, such as Figure 1 As shown, an adjustment mechanism 4 is provided between the coating mechanism 2 and the suspension oven 3. The adjustment mechanism 4 includes a lower pressure roller 41, which presses against the upper surface of the aluminum foil 5.

[0032] In this embodiment, the lower pressure roller 41 is used to prevent the vibration of the aluminum foil 5 caused by the hot air of the suspended oven 3 from being transmitted to the gravure roller 21, so that the aluminum foil 5 at the gravure roller 21 will not have slight scratches.

[0033] In some embodiments, such as Figure 2 As shown, the angle α between the aluminum foil 5 between the gravure roller 21 and the lower pressure roller 41 and the horizontal direction ranges from 2 to 8 degrees.

[0034] Specifically, the aluminum foil 5 is angled to prevent the vibration of the aluminum foil 5 from being transmitted to the gravure roller 21.

[0035] Specifically, the lower pressure roller 41 presses against the upper surface of the aluminum foil 5 to prevent it from coming into contact with the adhesive on the aluminum foil 5.

[0036] In this embodiment, the included angle α is in the range of 2-8 degrees in order to prevent the adhesive on the aluminum foil 5 from flowing due to gravity, provided that the vibration cannot pass over the lower pressure roller 41. If the included angle α is too small, the vibration will not be stopped, and if the included angle α is too large, the coated adhesive will flow.

[0037] In some embodiments, the lower pressure roller 41 is made of aluminum.

[0038] In this embodiment, using aluminum can reduce the overall weight of the lower pressure roller 41, making it easier for the lower pressure roller 41 to rotate.

[0039] In some embodiments, such as Figure 3 As shown, the adjustment mechanism 4 also includes a pair of lifting components 42; the two lifting components 42 are respectively connected to the two ends of the lower pressure roller 41, and are suitable for adjusting the height of the lower pressure roller 41.

[0040] In this embodiment, the included angle α is changed by adjusting the height of the lower pressure roller 41.

[0041] In some embodiments, such as Figure 3As shown, the lifting assembly 42 includes: a mounting frame 421 on which a slide groove 422 is provided; a slider 423 slidably disposed in the slide groove 422; and a bolt 424, which passes through the mounting frame 421 and extends into the slide groove 422 to connect with the slider 423, and is used to drive the slider 423 to rise and fall by rotation to adjust the height of the lower pressure roller 41.

[0042] In this embodiment, the end of the lower pressure roller 41 is connected to the slider 423, and the height of the lower pressure roller 41 is changed by adjusting the height of the slider 423.

[0043] In some embodiments, both ends of the bolt 424 are rotatably connected to the mounting bracket 421.

[0044] Specifically, bolt 424 can be made to rotate without moving by using a double bearing setup. The outer ring of the bearing is mounted on the mounting bracket 421, and the inner ring of the bearing is mounted on bolt 424; slider 423 moves between the two bearings.

[0045] In this embodiment, the bolt 424 will only rotate when subjected to force, and drive the slider 423 to rise and fall.

[0046] In some embodiments, the slider 423 passes through the bolt 424 and is threadedly connected to the bolt 424; wherein the bolt 424 is adapted to drive the slider 423 to move along the groove 422 by rotation.

[0047] In this embodiment, when the bolt 424 rotates, the slider 423 cannot rotate because it is restricted by the groove 422. Therefore, the slider 423 can move along the groove 422.

[0048] In some embodiments, such as Figure 3 As shown, a guide shaft 426 is provided on the mounting bracket 421; the slider 423 passes through the guide shaft 426; specifically, the guide shaft 426 is located in the slide groove 422.

[0049] In some embodiments, a bearing seat 425 is provided on the slider 423; the end of the lower pressure roller 41 is rotatably connected to the bearing seat 425; specifically, a bearing is sleeved on the end of the lower pressure roller 41, the outer ring of the bearing is connected to the bearing seat 425, and the inner ring of the bearing is connected to the lower pressure roller 41.

[0050] In some embodiments, such as Figure 2 As shown, the coating mechanism 2 also includes a doctor blade 22 and a glue spray nozzle 23; the doctor blade 22 is located downstream of the gravure roller 21, and the glue spray nozzle 23 is located upstream of the gravure roller 21; the glue spray nozzle 23 is adapted to spray glue onto the gravure roller 21, and the doctor blade 22 is adapted to adjust the thickness of the glue on the aluminum foil 5.

[0051] Specifically, the glue nozzle 23 is connected to a container containing glue. The glue is sprayed out from the glue nozzle 23 by the pump. The glue nozzle 23 has multiple spray outlets, which are arranged along the length of the gravure roller 21, so that the glue is sprayed above the gravure roller 21, thereby applying glue to the lower surface of the aluminum foil 5.

[0052] Specifically, the two ends of the scraper 22 are respectively set on a lifting plate, and the thickness of the adhesive coating is adjusted by moving the lifting plate.

[0053] Specifically, a receiving groove 24 is provided below the gravure roller 21, the doctor blade 22 and the glue spray nozzle 23 to receive excess glue. The receiving groove 24 is connected to a container holding the glue, and the glue in the receiving groove 24 is filtered and returned to the container holding the glue.

[0054] In some embodiments, such as Figure 1 As shown, the suspended oven 3 includes: a box body 31, on which a through channel 311 is provided for the aluminum foil 5 to pass through.

[0055] Specifically, an electric heating element and a centrifugal fan are installed in channel 311; the centrifugal fan is suitable for blowing the heat generated by the electric heating element onto the aluminum foil 5.

[0056] In summary, this aluminum-plastic film production line, by setting an adjustment mechanism 4 between the coating mechanism 2 and the suspension oven 3, allows the lower pressure roller 41 of the adjustment mechanism 4 to press against the upper surface of the aluminum foil 5, thereby preventing the vibration of the aluminum foil 5 caused by the hot air from the suspension oven 3 from being transmitted to the gravure roller 21 of the coating mechanism 2, thus preventing slight scratches from being generated on the aluminum foil 5 at the gravure roller 21.

[0057] In this document, when it is said that the first component is located on the second component, this can mean that the first component can be directly formed on the second component, or that the third component can be inserted between the first component and the second component.
