Description

Technical Field

[0001] This application relates to the field of reflective film processing technology, and in particular to an adhesive coating apparatus for reflective film processing. Background Technology

[0002] Reflective film is a thin-film material that can efficiently reflect light and is widely used in lighting, displays, solar energy, building energy conservation, and other fields. The processing of reflective film involves multiple stages, including material selection, coating process, lamination process, cutting and forming, and each stage has a significant impact on the performance of the final product.

[0003] The adhesive coating process for reflective films is a crucial step in reflective film manufacturing. Appropriate coating methods and adhesive types must be selected based on the application scenario and performance requirements of the reflective film. The adhesive is sprayed onto the reflective film through a nozzle. However, sedimentation can occur after prolonged storage, leading to decreased adhesive performance, uneven coating, and even equipment clogging. Therefore, this application presents an adhesive coating device for reflective film manufacturing to address this problem. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this application is to provide a coating apparatus for reflective film processing, thereby solving the technical problems in the background art.

[0005] The above-mentioned objective of this application is achieved through the following technical solution: a coating device for processing reflective film, comprising a base plate and a top plate fixedly connected to the upper end of the base plate, wherein the base plate is provided with a placement component for placing the reflective film to be coated, and a winding component for winding is also provided at one end of the placement component, a spraying frame is installed on the top plate, a plurality of spray nozzles are connected to the bottom of the spraying frame, a flexible transport pipe is connected to the spraying frame, the other end of the flexible transport pipe is connected to a storage tank for placing the spraying liquid, a transport pump is fixedly installed on the flexible transport pipe, and a stirring device is provided in the storage tank.

[0006] By adopting the above technical solution, the adhesive is mixed and stirred by a stirring device in this application, thereby avoiding the problem of sedimentation after the adhesive has been left for a long time. Then, the coating in the storage tank is transported through a flexible transport pipeline by a transport pump. At the same time, the flexible transport pipeline is also equipped with a valve and enters the hollow spraying frame. The reflective film at the bottom is sprayed by a spray nozzle. The reflective film is transported by a placement component and a winding component.

[0007] Furthermore, the stirring device includes a rotating shaft rotatably connected to the storage tank, a plurality of stirring plates fixedly connected to the shaft body of the rotating shaft, a drive motor fixedly connected to the upper end of the storage tank, and the output end of the drive motor fixedly connected to the rotating shaft.

[0008] By adopting the above technical solution, during stirring, the drive motor drives the rotating shaft to rotate, thereby driving the stirring plate to mix and stir the coating inside the storage tank.

[0009] Furthermore, a stirring inner layer is rotatably connected to the inner side of the storage tank, and multiple sets of mixing plates are fixedly arranged on the inner side of the stirring inner layer. A driven assembly for driving the stirring inner layer is provided on the storage tank.

[0010] By adopting the above technical solution, the driven component drives the inner stirring layer inside the storage tank to rotate together, and then the mixing plate mixes and stirs together, achieving the effect of mixing and stirring.

[0011] Furthermore, the driven component includes a driven shaft rotatably connected to the storage tank, a synchronous belt is sleeved between the rotating shaft and the driven shaft, a drive gear is fixedly connected to the shaft body of the driven shaft, the stirring inner layer extends out of the upper end of the storage tank, and a driven gear meshing with the drive gear is fixedly connected to the stirring inner layer.

[0012] By adopting the above technical solution, the drive motor drives the rotating shaft to rotate together. At this time, the synchronous belt drives the driven shaft to rotate, and the drive gear on the driven shaft drives the driven gear, so that the inner layer of the stirring can rotate and be mixed together.

[0013] Furthermore, a push cylinder is fixedly installed on the top plate, and the output end of the push cylinder is fixedly connected to the spray frame. A leveling component is installed on one side of the spray frame.

[0014] By adopting the above technical solution, the height of the spray gun can be adjusted by changing the cylinder settings.

[0015] Furthermore, the leveling assembly includes an adjusting cylinder fixedly connected to one side of the spraying frame, and a leveling blade is fixedly mounted on the output end of the adjusting cylinder.

[0016] By adopting the above technical solution, after the reflective film is sprayed, the reflective film is wound up by the winding assembly, which moves the reflective film and smooths it by the setting of the scraper, thereby improving the spraying effect of the reflective film.

[0017] Furthermore, the placement assembly includes a placement frame slidably connected to the upper end of the base plate, a placement shaft rotatably connected to the placement frame, a placement motor fixedly connected to one side of the placement frame, and the output end of the placement motor fixedly connected to the placement shaft. The winding assembly includes a winding frame slidably connected to the base plate, a winding shaft rotatably connected to the winding frame, a winding motor fixedly connected to the winding frame, and the output end of the winding motor fixedly connected to the winding shaft.

[0018] By adopting the above technical solution, the placement motor and the take-up motor drive the placement shaft and the take-up shaft to rotate together, and unwinding and rewinding are performed simultaneously.

[0019] Furthermore, both the winding frame and the placement frame are threaded with adjusting screws, which are rotatably connected to the base plate. An adjusting motor is fixedly mounted on the base plate, and the output end of the adjusting motor is fixedly connected to the adjusting screws.

[0020] By adopting the above technical solution, considering that different reflective film models require different tensions during production, this application includes threaded adjustment screws on both the winding frame and the placement frame. The distance between the placement shaft and the winding shaft is controlled by adjusting the motor, thereby changing their tension.

[0021] In summary, this application includes the following beneficial technical effects: Highly efficient anti-sedimentation is achieved through double-layer stirring technology. The outer stirring plate and the inner mixing plate rotate in opposite directions to form convection stirring, completely breaking the sedimentation trend of fillers or pigments in the adhesive, ensuring adhesive uniformity, extending adhesive storage time by more than 30%, reducing adhesive waste and frequent replacement costs caused by sedimentation, and simultaneously preventing the adhesive from separating during storage or transportation by continuous operation of the drive motor. This is especially suitable for high-viscosity, high-solids-content adhesives. Regarding coating uniformity, multiple nozzles uniformly spray to cover the full width of the reflective film, ensuring consistent adhesive layer thickness with a coating thickness deviation of ≤±2%, eliminating defects such as missed coating and uneven thickness, and improving the optical performance of the reflective film.

During stirring, the drive motor 3 drives the rotating shaft 31 to rotate, thereby driving the stirring plates 36 to mix and stir the coating inside the storage tank 2.

[0030] In this embodiment, a stirring inner layer 30 is rotatably connected to the inner side of the storage tank 2. Multiple mixing plates 37 are fixedly arranged on the inner side of the stirring inner layer 30. A driven assembly for driving the stirring inner layer 30 is provided on the storage tank 2.

Simultaneously, the drive gear 34 on the driven shaft 33 drives the driven gear 35, causing the stirring inner layer 30 to rotate and mix together.

[0032] In this embodiment, a push cylinder 24 is fixedly installed on the top plate 11.

The distance between the placement shaft 17 and the winding shaft 13 is controlled by adjusting the motor 15, thereby changing their tension.

[0036] Specific Implementation Process: The core working principle of this device revolves around preventing sedimentation during adhesive application, adhesive application and leveling, and reflective film transmission and tension control. Regarding preventing sedimentation during adhesive application, a double-layer stirring structure is adopted. The outer layer is driven by a motor 3, which rotates the rotating shaft 31 and stirring plate 36 to initially mix the adhesive. The inner layer is driven by a synchronous belt 32, with the driven shaft 33 driving the drive gear 34 to rotate. The drive gear 34 meshes with the driven gear 35, causing the inner stirring layer 30 and mixing plate 37 to rotate in opposite directions, forming convective stirring, significantly improving mixing efficiency, effectively preventing fillers or pigments in the adhesive from settling, and ensuring adhesive uniformity. In the adhesive application and leveling system, a transport pump delivers the adhesive from the storage tank through a flexible transport pipe 21 to the spraying frame 22, where it is evenly sprayed onto the reflective film surface through multiple nozzles 23. An adjustable cylinder 25 controls the height of the leveling blade 26 to smooth the sprayed adhesive layer, eliminating air bubbles and uneven thickness, thus improving the adhesive application quality. In terms of reflective film transmission and tension control, the placement motor 18 drives the placement shaft 17 to unwind, and the winding motor 14 drives the winding shaft 13 to wind, so as to realize the continuous transmission of reflective film; the adjustment motor 15 drives the adjustment screw 151 to rotate, adjusts the distance between the placement frame and the winding frame, changes the tension of the reflective film, and adapts to reflective films of different thicknesses and materials.

[0037] The operation process is divided into four steps: preparation, adhesive application, monitoring and adjustment, and final operation. Preparation includes pouring the adhesive into the storage tank and starting the mixing device; mounting the reflective film roll on the placement shaft 17 and securing the pulled-out end to the take-up shaft 13; and adjusting the height of the spray gun 22, the height of the scraper 26, and the tension according to the thickness and material of the reflective film. During the adhesive application, the placement motor 18, the take-up motor 14, the transport pump, and the spray gun 22 are started to begin unwinding, rewinding, and spraying. The reflective film is smoothed as it passes through the scraper 26. During the monitoring and adjustment phase, the adhesive application effect needs to be observed in real time, relevant parameters adjusted as needed, and the adhesive status in the storage tank checked periodically. At the end of the operation, all equipment is shut down, and the spray gun 22, scraper 26, and storage tank are cleaned to prevent the adhesive from hardening.

[0038] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
