Description

Technical Field

[0001] The utility model relates to the field of composite film production, in particular to an aluminum plating device for composite films. Background Art

[0002] In composite film aluminizing, the aluminum substrate and the plastic film are usually bonded together with glue to form a composite film. However, traditional composite film aluminizing usually uses a laminating machine to spray glue on the aluminum substrate, and then passes through a pressure roller to bond the plastic film and the aluminum substrate together.

[0003] However, there are some drawbacks when using a laminating machine to coat aluminum substrates: the laminating machine coats the glue from top to bottom, which can easily lead to uneven glue thickness during laminating, and glue overflow during machine downtime. To address these drawbacks, we propose an aluminum coating device for composite films. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose an aluminum plating device for composite membranes.

[0005] In order to solve the problems existing in the prior art, the present invention adopts the following technical solution: an aluminum plating device for a composite film, comprising:

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. By setting up a glue coating structure, the aluminum substrate is passed between the connecting roller and the receiving tray.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0032] See also Figure 1-4 The utility model provides a technical solution: an aluminum plating device for composite film, including: a frame, a gluing structure, a material discharging structure, a winding structure, an extrusion structure, and a guide structure.

[0033] See Figure 1 The frame includes a first mounting base 1, a second mounting base 2, and an oven 3 fixedly mounted on opposite sides of the first mounting base 1 and the second mounting base 2.

[0034] See Figure 3-4The gluing structure includes a connecting roller 4 and a gluing roller 5 which are respectively rotatably mounted on the inner wall of the second mounting seat 2, a scraper 6 which is fixedly mounted on the surface of the gluing roller 5, a spacing adjustment component arranged on the surface of the second mounting seat 2, and a glue placing component arranged inside the second mounting seat 2.

[0035] The glue placement component includes a track 7 fixedly mounted on the inner wall of the second mounting base 2, a receiving tray 8 arranged on the inner wall of the track 7, sliders 9 fixedly mounted on the front and back of the receiving tray 8, and a resistance adjustment component that can adjust the position of the receiving tray 8, and glue is placed on the receiving tray 8.

[0036] See Figure 2 The resistance adjustment assembly includes a threaded rod 10 threadedly connected to the inner wall of the track 7, a stopper 11 fixedly installed at the left end of the threaded rod 10, a through hole opened on the surface of the slider 9 for the threaded rod 10 to pass through, and a compression spring 12 sleeved on the surface of the threaded rod 10. The surface of the threaded rod 10 is slidably connected to the inner wall of the through hole, one end of the compression spring 12 is fixedly connected to the right end of the slider 9, and the other end of the compression spring 12 overlaps the inner wall of the track 7.

[0037] Rotating the threaded rod 10 can drive the stopper 11 and the slider 9 to move, thereby changing the distance between the receiving tray 8 and the connecting roller 4. On the one hand, the position of the receiving tray 8 can be fine-tuned according to the thickness of the aluminum substrate. On the other hand, the compression spring 12 can drive the receiving tray 8 to always contact the aluminum substrate to avoid glue leakage.

[0038] See Figure 2 and Figure 4 The spacing adjustment assembly includes an adjustment frame 21 fixedly mounted on the front and back sides of the second mounting seat 2, an adjustment bolt 22 threadedly connected to the upper surface of the adjustment frame 21, and an adjustment block 23 rotatably mounted on the lower end of the adjustment bolt 22. The adjustment block 23 is located inside the adjustment frame 21, and a through slot for the adjustment block 23 to pass through is provided on the front and back sides of the second mounting seat 2. One end of the adjustment block 23 passes through the through slot and is fixedly connected to one end of the glue coating roller 5.

[0039] Rotating the adjusting bolt 22 can drive the adjusting block 23 to slide along the inner wall of the through groove, thereby driving the glue coating roller 5 to move synchronously, and then changing the distance between the scraper 6 and the connecting roller 4. Therefore, the height of the scraper 6 can be adjusted according to the thickness of the aluminum substrate. By utilizing the cooperation of the spacing adjustment component and the resistance adjustment component, aluminum substrates of different thicknesses can be coated with glue.

[0040] See Figure 3 The discharge structure is respectively arranged inside the first mounting seat 1 and the second mounting seat 2, and is used for discharging the film and the aluminum substrate. The discharge structure includes a film discharge roller 13 rotatably mounted on the inner wall of the first mounting seat 1, and a substrate discharge roller 14 rotatably mounted on the inner wall of the second mounting seat 2.

[0041] The guiding structure is respectively arranged inside the first mounting seat 1 and the second mounting seat 2, and is used to guide the aluminum substrate and the film. The guiding structure includes a first guide roller 16 and a second guide roller 17 respectively rotatably mounted on the inner wall of the first mounting seat 1, and a third guide roller 18 rotatably mounted on the inner wall of the second mounting seat 2.

[0042] The extrusion structure is arranged inside the first mounting seat 1 for extruding the aluminum substrate and the film. The extrusion structure includes a first extrusion roller 19 and a second extrusion roller 20 which are rotatably mounted on the inner wall of the first mounting seat 1 respectively.

[0043] The winding structure is arranged inside the first mounting seat 1 for winding the composite film. The winding structure includes a winding roller 15 rotatably mounted on the inner wall of the first mounting seat 1 .

[0044] The aluminum substrate is passed between the receiving tray 8 and the connecting roller 4, and then between the connecting roller 4 and the scraper 6, and then through the oven 3. At this time, the surface of the aluminum substrate overlaps with the surfaces of the third guide roller 18 and the second guide roller 17 respectively, and then passes between the first squeezing roller 19 and the second squeezing roller 20. Then, the film is passed between the first squeezing roller 19 and the second squeezing roller 20, and finally the film and the aluminum substrate are fixed on the receiving roller 15. When the receiving roller 15 receives the material, the aluminum substrate and the film will be wound around the receiving roller 15. At this time, when the aluminum substrate passes through the receiving tray 8, the aluminum substrate will adhere to the glue. When the aluminum substrate with glue adhered passes through the scraper 6, the scraper 6 will scrape off the excess glue on the aluminum substrate, thereby ensuring that the glue thickness on the aluminum substrate is uniform, and the glue scraped off by the scraper 6 will flow back into the receiving tray 8, so that the scraped glue can be reused.

[0045] When the aluminum substrate with glue adhered to it passes through the oven 3, the oven 3 can preliminarily bake the glue, so that the glue can reach the required performance and stability more quickly. When the preliminarily dried glue passes between the first squeezing roller 19 and the second squeezing roller 20, the glue will adhere the aluminum substrate and the film into one, thereby performing aluminum plating. Finally, after the aluminum plating is completed, it can be wound up using the receiving roller 15.

[0046] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited thereto. Any equivalent replacement or change made by a person skilled in the art based on the technical solution and concept of the present invention should be included in the protection scope of the present invention.
