Description

Technical Field

[0001] This utility model relates to aluminum-coated film laminating equipment, and in particular to a multi-roller extrusion coating laminating mechanism. Background Technology

[0002] Chinese utility patent CN214027668U discloses an aluminum-coated film composite mechanism. The pressure roller is positioned above the coating roller, and an adhesive channel is formed between the pressure roller and the coating roller, through which the aluminum-coated film can pass. When the aluminum-coated film passes through the adhesive channel, it is coated with adhesive. However, for adhesives with high concentrations, there are issues with uneven and unstable adhesive application. Utility Model Content

[0003] In view of the technical problems existing in the background art, the present invention aims to provide a multi-roller extrusion coating composite mechanism, wherein the coating roller and the coating pressure roller are staggered on the first feeding path, and the film belt forms a small arc-shaped contact surface on the coating roller, and the glue is uniformly and firmly scraped onto the arc-shaped contact surface.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This multi-roller extrusion coating and laminating mechanism includes a frame, on which a second feeding roller group and a first feeding roller group are provided. The second feeding roller group forms a second feeding path, and the first feeding roller group forms a first feeding path. The second feeding path and the first feeding path converge at the laminating station. The first feeding path is provided with a coating station, which is equipped with a coating roller and a coating pressure roller. On the first feeding path, the coating roller and the coating pressure roller are staggered, and the coating pressure roller is located on the glue inlet side of the coating station.

[0005] In this scheme, the coating roller and the coating pressure roller are staggered on the first feeding path, and the film belt forms a small arc-shaped contact surface on the coating roller, so that the glue is evenly and firmly coated on the arc-shaped contact surface.

[0006] Preferably, at the glue application station, the first material is conveyed from front to back, the glue application roller rotates from front to back, and the glue application pressure roller is located in front of the glue application roller on the first feeding path.

[0007] In this method, the adhesive is applied in the same direction and evenly.

[0008] Preferably, the composite workstation is equipped with a composite pressure roller and a cold water roller.

[0009] In this scheme, the cold water roller cools and shapes the first and second materials when they are combined.

[0010] Preferably, it also includes a drying station, which is equipped with a hot cylinder mirror roller and a discharge pressure roller, and a drive transition steel roller connects the drying station and the composite station.

[0011] In this scheme, the hot cylinder mirror roller dries, shapes, and calenders the composite material.

[0012] Preferably, a glue box is provided below the glue coating roller, and an upper glue roller connects the glue box and the glue coating roller. The upper glue roller is raised and lowered, and the rotation direction of the upper glue roller is opposite to that of the glue coating roller.

[0013] In this scheme, the glue-applying roller transfers the glue in the glue box to the glue-coating roller. Raising and lowering the glue-applying roller moves it closer to or further away from the glue-coating roller. The glue-applying roller and the glue-coating roller rotate in opposite directions, and the gap between them can control the glue thickness.

[0014] Preferably, the linear speed of the coating roller is lower than the first feeding speed.

[0015] In this scheme, the adhesive on the surface of the coating roller is uniformly and firmly scraped onto the arc-shaped contact surface through the speed difference.

[0016] Preferably, the glue-applying roller is equipped with a scraper roller, which is close to or away from the glue-applying roller.

[0017] In this scheme, the amount of glue applied is controlled by adjusting the gap between the scraper roller and the glue applicator roller.

[0018] Preferably, the adhesive roller is mounted on a swing arm, one end of which is hinged to the frame, and the other end of which is hinged to the output shaft of the lifting cylinder.

[0019] In this design, a cylinder drives a swing arm to swing, which in turn raises and lowers the adhesive coating roller.

[0020] Preferably, a limit handle is provided below the swing arm.

[0021] In this design, the limit handle limits the downward pressing position of the adhesive application roller.

[0022] Preferably, the first feeding roller group includes a flattening roller and a guide roller. The flattening roller is located on the film inlet side of the glue coating station, and the guide roller is located on the film outlet side of the glue coating station. The lowest point of the glue coating pressure roller is located below the line connecting the highest point of the glue coating roller and the highest point of the flattening roller, and the highest point of the glue coating roller is located above the line connecting the lowest point of the glue coating pressure roller and the lowest point of the guide roller.

[0023] In this scheme, the first material passes around the flattening roller and the guide roller, and the glue-applying roller and the glue-applying pressure roller respectively contact the first material to form an arc-shaped contact surface.

[0024] The beneficial effects of this invention are as follows: the coating roller and the coating pressure roller are staggered in the first feeding path, the first material forms a small arc-shaped contact surface on the coating roller, and the adhesive on the surface of the coating roller is uniformly and firmly coated onto the arc-shaped contact surface through the speed difference. The cold water roller cools and shapes the first and second materials when they are compounded, and the hot cylinder mirror roller dries, shapes, and calenders the compounded material. Therefore, this invention has substantial features and progress compared with the prior art. Attached Figure Description

[0031] See appendix Figure 1An embodiment of this invention provides a multi-roller extrusion coating and laminating mechanism, comprising a frame 1, on which a second feeding roller group 13 and a first feeding roller group 2 are provided. The second feeding roller group 13 forms a second feeding path, and the first feeding roller group 2 forms a first feeding path. The second feeding path and the first feeding path converge at a laminating station. The laminating station is equipped with a laminating pressure roller 14 and a cold water roller 15. It also includes a drying station, which is equipped with a hot cylinder mirror roller 16 and a discharge pressure roller 17. A drive transition steel roller 18 connects the drying station and the laminating station.

[0032] The first feeding path includes a gluing station equipped with a gluing roller 3 and a gluing pressure roller 4. The gluing roller 3 and the gluing pressure roller 4 are staggered along the first feeding path, with the gluing pressure roller 4 positioned before the gluing roller 3. The first feeding roller group 2 includes a flattening roller 11 and a guide roller 12. The flattening roller 11 is located on the film inlet side of the gluing station, and the guide roller 12 is located on the film outlet side of the gluing station. The lowest point of the gluing pressure roller 4 is located below the line connecting the highest point of the gluing roller 3 and the highest point of the flattening roller 11. The highest point is located above the line connecting the lowest point of the coating roller 4 and the lowest point of the guide roller 12. The linear speed of the coating roller 3 is lower than the first feeding speed. The coating roller 4 is mounted on the swing arm 8. One end of the swing arm 8 is hinged to the frame 1, and the other end of the swing arm 8 is hinged to the output shaft of the lifting cylinder 9. A limit handle 10 is provided below the swing arm 8. A glue box 5 is provided below the coating roller 3. The glue roller 6 connects the glue box 5 and the coating roller 3. The glue roller 6 is raised and lowered. The glue roller 6 is equipped with a scraper roller 7, which is close to or away from the glue roller 6.

[0033] In this embodiment, glue adheres to the surface of the gluing roller 6 inside the glue box 5 (the glue box 5 and the gluing roller 6 are mounted together on the lifting seat, which is driven by a cylinder for lifting). When passing the scraping roller 7, the scraping roller 7 scrapes the glue layer on the surface of the gluing roller 6 evenly. When the surface of the gluing roller 6 passes the coating roller 3, the glue is transferred to the surface of the coating roller 3 and forms a glue layer of a certain thickness (the coating roller 3 and the gluing roller 6 are linked). The coating roller 3 transfers the glue to the first material at the coating station. The first material reaches the coating station via the flattening roller 11. The material is then guided away from the coating station by the guide roller 12. The center of the coating roller 4 and the center of the coating roller 3 are misaligned in the vertical direction (this design is not limited to this in this embodiment). The first material and the second material are combined at the composite station. The cold water roller 15 cools and shapes the material while it is being combined. The combined material is driven by the transition steel roller 18 to the drying station. The hot cylinder mirror roller 16 dries, shapes, and calenders the material when it is discharged (the cold water roller 15, the transition steel roller 18, and the hot cylinder mirror roller 16 are linked).

[0034] The swing arm 8 is provided with a corresponding limit block of the limit handle 10. The limit block abuts against the handle of the limit handle 10 to restrict the swing arm 8 from swinging further. The limit handle 10 is threadedly engaged with the mounting seat on the frame 1. Rotating the extension handle of the limit handle 10 adjusts the gap between the glue application roller 4 and the glue application roller 3.

[0035] The glue-infeed side of the glue-coating roller 3 is defined by the first feeding path as the first material conveying direction at the glue-coating station as from front to back. If the glue-coating roller 3 rotates in the same direction (the surface of the glue-coating roller 3 reaches the glue-coating station from the front side and leaves the glue-coating station to reach the rear side, which is also the definition that the rotation direction of the glue-coating roller 3 at the glue-coating station is from front to back), then the glue-infeed side is the front side of the glue-coating roller 3. If the glue-coating roller 3 rotates in the opposite direction, then the glue-infeed side is the rear side of the glue-coating roller 3.

[0036] The scraper roller 7 is mounted on the mounting base, which is connected to a nut. The nut is threaded with a screw, and rotating the screw can adjust the position of the scraper roller 7.

[0037] The linkage can be a synchronous belt and synchronous pulley, or a synchronous pulley connected to a gear, which drives the corresponding roller shaft to rotate through gear meshing.

[0038] In other alternative embodiments, the rotation direction of the coating roller 3 may be opposite to the first material conveying direction (suitable for thick coating), the rotation direction of the gluing roller 6 may be the same as the rotation direction of the coating roller 3, and the gluing pressure roller 4 may be raised and lowered.

[0039] The above description represents the preferred embodiment of this utility model. It should be noted that the protection scope of this utility model is not limited thereto. For those skilled in the art, various improvements, modifications, or equivalent substitutions can be made without departing from the equivalent inventive concept disclosed in this utility model, and these modifications and substitutions are also considered to be within the protection scope of this utility model.
