But the present glue roller and the base material often have too large wrap angle, which causes the base material to stay on the glue roller for a long time, the base material is elongated, and the size of the base material changes, which affects the uniform distribution and wiping effect of the glue, and causes the uneven glue surface.

[0036] Specifically, the substrate is wound on the first unwinding mechanism 100, and the film to be compounded is wound on the second unwinding mechanism 500, and the substrate has a gluing surface for gluing. The first unwinding mechanism 100 is used to unwind the substrate, and is arranged on the left side. The second unwinding mechanism 500 is used to unwind the film to be compounded, and is arranged on the right side. The first unwinding mechanism 100 and the second unwinding mechanism 500 can be, but are not limited to, unwinding rollers. The gluing mechanism 200 is used to glue the substrate, and is arranged on the left side of the first unwinding mechanism 100. In the gluing mechanism 200, the gluing roller 210 is at least partially arranged in the glue. The roller pressing plane of the gluing roller 210 is arranged as a top plane. The gluing pressing roller 220 is arranged in correspondence with the gluing roller 210. The top plane of the gluing roller 210 is arranged in parallel with the gluing surface of the substrate. The gluing roller 210 and the gluing pressing roller 220 convey the substrate towards the left end, that is, the gluing roller 210 rotates counterclockwise, and the gluing pressing roller 220 rotates clockwise. The oven 300 is used to dry the glued substrate. The oven 300 is arranged above the gluing mechanism 200, the first unwinding mechanism 100 and the second unwinding mechanism 500. The oven 300 is arranged as a conventional oven 300, and has a plurality of transmission rollers inside. The way in which the oven 300 dries the glue on the substrate is known to those skilled in the art, and can be achieved. In this embodiment, it is not described in detail. The pressing mechanism 400 is used to press the film onto the substrate to form a composite film. The pressing mechanism 400 is arranged between the oven 300 and the winding mechanism 600, and is arranged on the right side of the oven 300 and the winding mechanism 600. The winding mechanism 600 is used to wind up the composite film formed by pressing. The winding mechanism 600 can be, but is not limited to, a winding roller. The working mode of the first unwinding mechanism 100, the second unwinding mechanism 500 and the winding mechanism 600 is known to those skilled in the art, and can be achieved. In this embodiment, it is not described in detail.

[0037] It is worth mentioning that, in use, the first unwinding mechanism 100 unwinds the substrate, and the glue mechanism 200 is glued, and after the glue is completed, the substrate is conveyed to the oven 300, the glue on the substrate is dried through the oven 300, and then the substrate is discharged from the oven 300 until it reaches the pressing mechanism 400, at this time, the pressing mechanism 400 is pressed into a composite film with the film unwound from the second unwinding mechanism 500, and finally, the winding mechanism 600 is wound to complete the entire compounding process. Wherein, when the glue mechanism 200 glues, the roll pressing plane of the glue roller 210 is arranged to be parallel to the substrate, and the glue roller 210 and the glue pressing roller 220 both push the substrate away from the first unwinding mechanism 100, so that the substrate during the gluing process is more flat, and the wrap angle between the substrate and the glue roller 210 is smaller. As can be seen, through the design of small wrap angle and along the conveying direction of the substrate, the time of the substrate staying on the glue roller 210 can be avoided for too long, therefore, the substrate can maintain the original size, so that the glue roller 210 can evenly smear the glue on the gluing surface of the substrate during work, and the glue surface of the substrate is more flat, thereby effectively avoiding the phenomenon of white spots and low local peeling strength of the obtained composite film.

[0038] Embodiment 2

[0039] This embodiment is a further implementation of embodiment 1, as shown in Figure 2 In this embodiment, the glue pressing roller 220 is arranged opposite to the glue roller 210 in the vertical plane, and the roll pressing plane of the glue pressing roller 220 is arranged to be flush with the back glue surface of the substrate unwound from the first unwinding mechanism 100.

[0040] Specifically, the roll pressing plane of the glue pressing roller 220 is arranged as a bottom plane, and the bottom surface of the glue pressing roller 220 is arranged to be flush with the upper end plane of the substrate unwound from the first unwinding mechanism 100, so that the substrate unwound from the first unwinding mechanism 100 can be horizontally conveyed to the glue pressing roller 220, the wrap angle between the substrate and the glue pressing roller 220 is smaller, and the substrate can be in line contact with the roll pressing plane of the glue roller 210, so that the gluing effect is better.

[0041] In order to make the glue surface more flat, as shown in Figure 1 and Figure 2 In some embodiments, a leveling roller 240 is arranged between the glue mechanism 200 and the oven 300 for pushing the glue on the glue surface of the substrate, and the leveling roller 240 rotates to abut the glue surface of the substrate.

[0042] Specifically, the leveling roller 240 is arranged between the glue mechanism 200 and the oven 300, and is arranged on the left side of the glue mechanism 200 to level the glue on the glue surface of the substrate, thereby further leveling the glue on the glue surface of the substrate, so that the flatness of the glue surface of the substrate is higher.

[0043] To facilitate a smaller wrap angle for the coating roller 240 during the coating process, such as Figure 2 As shown, in some embodiments, the coating roller 240 is arranged in line contact with the adhesive surface of the substrate.

[0044] Specifically, the coating roller 240 and the substrate are arranged parallel to each other to make line contact, thereby making the contact area between the substrate and the coating roller 240 more uniform, the wrap angle smaller, and the smoothing effect better during transportation.

[0045] To facilitate contact between the coating roller 240 and the substrate line, such as Figure 2 As shown, in some embodiments, a guide roller 310 is provided between the oven 300 and the coating roller 240, and the guide roller 310 and the glue-applying roller 220 are arranged opposite each other on the vertical plane.

[0046] Specifically, the guide roller 310, the glue-applying roller 220, and the glue-applying roller 210 are arranged sequentially from top to bottom on the same vertical plane. The guide roller 310 is located on the adhesive-back side of the substrate, so that the coating roller 240 can be arranged parallel to this vertical plane. In this way, while ensuring line contact between the coating roller 240 and the substrate, the substrates on both sides of the glue-applying roller 220 can be perpendicular to each other, making the wrap angle between the substrate and the glue-applying roller 220 smaller and the size of the substrate more stable.

[0047] To facilitate the use of the pressing mechanism 400, such as Figures 1 to 3 As shown, in some embodiments, the pressing mechanism 400 includes a left pressing roller 410 and a right pressing roller 420, which are arranged opposite to each other to press the substrate and the film into a composite film.

[0048] Specifically, the left pressing roller 410 and the right pressing roller 420 are disposed on the right side of the oven 300, and are positioned opposite each other on the horizontal plane, so as to roll the substrate flowing out of the oven 300 and the film flowing out of the second unwinding mechanism 500 into a composite film in the horizontal direction. In addition, the working method of the left pressing roller 410 and the right pressing roller 420 is known to those skilled in the art and is feasible, and will not be described in detail in this embodiment.

[0049] To facilitate the application of glue to the gluing roller 210, such as Figures 1 to 3 As shown, in some embodiments, the gluing mechanism 200 further includes a glue pool 230 for containing glue, and the gluing roller 210 is partially disposed in the glue pool 230.

[0050] Specifically, the glue pool 230 contains glue and is located below the upper glue roller 210. The bottom plane of the upper glue roller 210 is in contact with the glue in the glue pool 230, so that the glue in the glue pool can be spread onto the substrate by rotating the upper glue roller 210.

[0051] Embodiment 3

[0052] The present embodiment is a further implementation of Embodiment 1 or 2, in which the gap between the roll plane of the sizing roller 210 and the back sizing surface of the substrate is controlled to be 10-20 μm.

[0053] In this way, by controlling the gap between the top plane of the sizing roller 210 and the sizing surface of the substrate, the sizing amount can be controlled. The specific gap between the roll plane of the sizing roller 210 and the back sizing surface of the substrate is not limited and can be determined according to actual production requirements. For example, the gap between the roll plane of the sizing roller 210 and the back sizing surface of the substrate is controlled to be 10 μm; for another example, the gap between the roll plane of the sizing roller 210 and the back sizing surface of the substrate is controlled to be 15 μm; for yet another example, the gap between the roll plane of the sizing roller 210 and the back sizing surface of the substrate is controlled to be 20 μm.

[0054] It can be understood that, for the composite film produced by the device and the gap, when the composite film is a high-temperature cooking product, the sizing amount of the substrate is reduced from the original 4.5 g / m 2 to 2.5 g / m 2 ~3 g / m 2 . When the composite film is a composite AL film or a composite MPET (Metallized Polyethylene Terephthalate) film, the sizing amount of the substrate is reduced from the original 2.5 g / m 2 ~2.8 g / m 2 to 1.5 g / m 2 .

For example, it can be fixed connection, or detachable connection, or integral; it can be mechanical connection, or electrical connection; it can be direct connection, or indirect connection through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

[0056] In the description of the utility model, it is necessary to explain that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship commonly placed when the utility model product is used, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the utility model. In addition, the terms "first", "second", "third" and the like are only used for differentiation in description and cannot be understood as indicating or implying relative importance.

[0057] In addition, the terms "horizontal", "vertical", "overhang" and the like do not mean that the components must be absolutely horizontal or overhanging, but can be slightly inclined. For example, "horizontal" only means that its direction is relatively more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0058] In the utility model, unless otherwise explicitly specified and limited, the first feature above or below the second feature can include that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact through another feature therebetween. Moreover, the first feature above, above and above the second feature includes that the first feature is directly above and obliquely above the second feature, or only means that the horizontal height of the first feature is higher than that of the second feature. The first feature below, below and below the second feature includes that the first feature is directly below and obliquely below the second feature, or only means that the horizontal height of the first feature is less than that of the second feature.
