Description

Technical Field

[0001] This utility model relates to the field of electronic thin film lamination technology, specifically a multi-roller flexible composite film continuous lamination mechanism. Background Technology

[0002] With the rapid development of emerging fields such as flexible electronics and the Internet of Things, the application of flexible composite thin film materials is becoming increasingly widespread. These materials typically need to possess good mechanical properties, electrical and thermal conductivity, and electromagnetic shielding capabilities simultaneously to meet the stable operation requirements of electronic devices in complex environments.

[0003] In the preparation of flexible composite films, the lamination process is a crucial step that determines product quality. Traditional lamination equipment suffers from the following problems:

[0004] Insufficient uniformity of pressing: Single-roller or simple double-roller structures are prone to uneven stress on the film, resulting in wrinkles or insufficient pressing in some areas.

[0005] Tension adjustment is difficult: it is hard to adapt to changes in different material properties and production speeds, affecting product consistency.

[0006] Incomplete bubble elimination: Bubbles are easily left after a single pressing, which reduces the mechanical and electrical properties of the material.

[0007] These problems are particularly prominent when preparing high-performance electromagnetic shielding and thermally conductive composite films. For example, composite films based on cellulose nanofibers (CNF) and novel two-dimensional materials such as MXene require precise control of the lamination process to ensure that the functional fillers form a continuous network structure, which places higher demands on the lamination equipment.

[0008] While some multi-roller pressing devices have emerged in the existing technology, they still have shortcomings in terms of synchronous adjustment, continuous pressure defoaming, and adaptability to the properties of flexible materials. Therefore, developing a continuous pressing mechanism that can achieve uniform pressing, flexibly adjust tension, effectively eliminate air bubbles, and adapt to various material properties has become an important requirement in the field of flexible composite film preparation.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Example 1:

[0040] See attached document Figures 1 to 4 A multi-roller flexible composite film continuous pressing mechanism, comprising:

[0041] Two mounting brackets, 100;

[0042] The pressing unit 200 is disposed between two mounting brackets 100. The pressing unit 200 includes two hot pressing rollers 201 for pressing the composite film. Both ends of the two hot pressing rollers 201 are fixedly connected with meshing gears 202.

[0043] The composite film can be pressed by combining two hot press rollers 201. The two ends are equipped with meshing gears 202 to ensure the symmetry and synchronization of the rotation of the two hot press rollers 201, thereby reducing the problem of tearing of the composite material during the pressing process. Note: The hot press rollers 201 adopt the roller body with heating function in the prior art, so it will not be described in detail here.

[0044] An adjustment unit 300 is disposed between two mounting brackets 100 and is used to adjust the angle of the two hot press rollers 201 to adjust the tension of the composite film.

[0045] The adjustment unit 300 is used to adjust the angle of the two hot press rollers 201, thereby realizing the tension adjustment of the composite film. This prevents the deformation of the composite film and the winding and unwinding errors during the hot pressing process from causing changes in tension and affecting the normal pressing operation of the composite film.

[0046] A continuous pressurizing unit 400 is disposed between one side of the two mounting brackets 100, and the continuous pressurizing unit 400 is used to apply secondary pressure to the composite film after it has been pressed by the pressing unit 200.

[0047] By setting up the continuous pressing unit 400, not only is secondary pressing of the composite film realized, but also the air bubbles produced after one round of pressing can be removed, thereby improving the pressing preparation effect of the composite film.

[0048] See attached document Figure 1 Two guide pressing rollers 101 for guiding and conveying at least two sets of film raw materials to the pressing unit 200 are rotatably connected between the sides of the two mounting brackets 100 via brackets.

[0049] The two guide pressing rollers 101 are used to initially press at least two raw material films of the composite film and transport them in an orderly manner to the pressing unit 200 to form subsequent orderly pressing work.

[0050] See attached document Figure 2 and Figure 3 The adjustment unit 300 includes two rotating disks 301 that are rotatably connected inside the two mounting brackets 100 respectively, and the two ends of the two hot press rollers 201 are rotatably connected inside the two rotating disks 301 respectively; a drive component for adjusting the angle of the two rotating disks 301 is provided between the two mounting brackets 100.

[0051] By providing a drive unit for adjusting the angle of the two rotating disks 301, the two rotating disks 301 can be rotated clockwise and counterclockwise, which can simultaneously drive the two hot press rollers 201 to perform circumferential motion. This allows a portion of the composite film to be wound, thus achieving tension adjustment. Furthermore, the winding of a portion of the composite film also forms a preliminary preheating process, thereby improving the effect of subsequent hot pressing.

[0052] Example 2: The difference from Example 1 is that;

[0053] See attached document Figure 2 and Figure 3 The driving component includes a lifting seat 302 slidably connected between two mounting brackets 100, and an inclined transmission frame 303 is hinged to the top of each of the two lifting seats 302. The top ends of the two transmission frames 303 are respectively hinged to the outer edges of the two rotating disks 301. A first displacement member 304 for adjusting the lifting seat 302 up and down is fixedly connected to the inner side of one of the mounting brackets 100.

[0054] The first displacement component 304 is used to drive the lifting seat 302 to adjust up and down, which in turn drives the two inclined transmission frames 303 to move in a fan shape. Finally, the two rotating disks 301 drive the two hot press rollers 201 to adjust clockwise and counterclockwise, thus forming a synchronous adjustment of the tension of the composite film before and after pressing.

[0055] Note: The first displacement component 304 includes, but is not limited to, components such as an electric telescopic rod or lead screw for adjusting the lifting seat 302 up and down, used to realize electric or manual adjustment.

[0056] Example 3: The difference from Example 1 is that;

[0057] See attached document Figure 4 The continuous pressurization unit 400 includes a fixed frame 401 fixed between one side of two mounting frames 100, and the fixed frame 401 is provided with a conveyor belt 402 for conveying the composite film after one round of pressing.

[0058] The conveyor belt 402 is used to transport the film pressed by the pressing unit 200, and the fixed frame 401 is provided with a transmission roller and a drive motor for driving the conveyor belt 402.

[0059] The top of the fixed frame 401 is provided with a pressure device for defoaming and pressurizing the composite film conveyed by the conveyor belt 402;

[0060] When the composite film conveyed by the conveyor belt 402 is pressurized by the pressurizing component, not only are multiple pressing operations formed, but also air bubbles in the composite film after one round of pressing can be effectively removed, thereby improving the pressing preparation effect.

[0061] The pressurizing component includes a gantry frame 403 fixed to the top of the fixed frame 401. A movable frame 404 is slidably connected inside the gantry frame 403. A V-shaped pressing rod 405 is fixedly connected to the bottom of the movable frame 404 through a bracket. A second displacement component 406 for adjusting the movable frame 404 up and down is provided on the gantry frame 403.

[0062] The second displacement member 406 is used to drive the movable frame 404 to move up and down, thereby driving the V-shaped pressing rod 405 to press the composite film. The pressing rod is V-shaped, which makes it easy to disperse the air bubbles in the film after the composite film is pressed by the pressing unit 200. The V-shaped pressing rod 405 can be spread on both sides of the film to eliminate the air bubbles, thus improving the pressing effect of the composite film preparation.

[0063] Note: The second displacement component 406 includes, but is not limited to, components such as an electric telescopic rod or lead screw for adjusting the movable frame 404 up and down, used to realize electric or manual adjustment.

[0064] A protective layer 407 is fixedly connected to the top of the mounting bracket 401;

[0065] The protective layer 407 is used to protect the pressure of the V-shaped pressing rod 405 on the composite film, preventing the pressing pressure of the V-shaped pressing rod 405 from directly acting on the composite film and easily causing scratches or other damage to the composite film.

[0066] Note: Protective layer 407 is made of protective fabric, non-woven fabric, or other materials that can protect the sharp corners of the V-shaped push bar 405;

[0067] The fixed frame 401 has a support plate 408 for auxiliary support of the conveyor belt 402.

[0068] The support plate 408 is used to support the pressure-bearing position of the conveyor belt 402, further improving the pressing effect of its V-shaped pressing rod 405 on the composite film.

[0069] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
