Technical Field
[0001] This utility model relates to the technical field of pre-applied coating mechanism, specifically a pre-applied coating mechanism for a light-enhancing composite film. Background Technology
[0002] Brightening composite film is a high-performance film material made by combining polypropylene or other substrates with other functional layers through a special process. It has excellent optical properties, which can significantly improve the gloss and visual effect of packaging. At the same time, it has good barrier properties, heat resistance and mechanical strength. It is widely used in the packaging of high-end products such as food, pharmaceuticals and cosmetics, which can effectively protect products and enhance the aesthetics and added value of packaging. In the processing of brightness enhancement composite films, "pre-lamination" refers to the operation of pre-laminating a thin film onto the surface of the substrate before the formal lamination process. This process is called "pre-lamination coating" and its purpose is to provide additional protection or enhance the performance of the substrate during subsequent processing or use. In the process of pre-applying and laminating brightness enhancement composite films, in addition to common flat objects, it is often necessary to deal with objects with certain curved shapes. However, when the object to be laminated is a curved surface, many challenges are faced. Due to the complex geometry of the curved surface, it is difficult for the film material to be completely adhered to the object surface during the lamination process. This may lead to localized poor adhesion or delamination. These problems not only affect the overall effect and quality of the lamination, but also increase the difficulty of quality control. Therefore, a pre-applying and laminating mechanism for brightness enhancement composite films is proposed to address the above problems. Utility Model Content

[0015] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

[0016] Please see Figure 1-6 This utility model provides a technical solution: A pre-applying and coating mechanism for a light-enhancing composite film includes a base plate 1, a conveying device 2, a stand 3, and a material roller 4. A drive assembly 5 is fixedly connected to the top of the base plate 1, and a coating assembly 6 is installed inside the drive assembly 5. The drive assembly 5 includes a mounting plate 51, one side of which is fixedly connected to the housing of a servo motor 52. A ball bearing 53 is fixedly connected to the inside of the mounting plate 51. The coating assembly 6 includes a hollow cylinder 61, the outer side of which is fixedly connected to the inner side of a fixing port 63. The fixing port 63 is located inside an air bladder 62. A connecting port 64 and an air vent 65 are provided inside the hollow cylinder 61. A spring 66 is fixedly connected to the inside of the hollow cylinder 61. A column block 67 is fixedly connected to one end of the spring 66, and a sealing rubber ring 68 is fixedly connected to the outer side of the column block 67.
[0017] As a further implementation of this solution, a transmission device 2 is fixedly connected to the top of the base plate 1. The transmission device 2 includes a bracket, and a drive motor is fixedly connected to the right side of the bracket. A rotating roller is rotatably connected to the inner side of the bracket of the transmission device 2, and a conveyor belt is sleeved on the outer side of the rotating roller of the transmission device 2. The end of the main shaft of the drive motor of the transmission device 2 is fixedly connected to the rotating roller of the transmission device 2. The transmission device 2 is located at the lower end of the coating assembly 6. The rotating roller at the rear end of the transmission device 2 is vertically aligned with the coating assembly 6. Through the above settings, the automatic conveying function of the conveyor belt is realized, thereby improving the automation and efficiency of the coating process, and enhancing the smoothness and stability of the overall coating operation. The vertical alignment of the rotating roller of the transmission device 2 with the coating assembly 6 can prevent the curved object from moving downwards when coating curved objects, thus improving the stability of coating curved objects. As a further implementation of this solution, the top of the base plate 1 is fixedly connected to the support frame 3 by bolts. The support frame 3 has a shaft hole on its inner side, and a material roller 4 is sleeved inside the shaft hole of the support frame 3. Through the above arrangement, the material roller 4 can rotate flexibly, which facilitates the release of the brightness enhancement composite film. At the same time, the bolt fixing method allows the brightness enhancement composite film on the outside of the material roller 4 to be replaced. As a further implementation of this solution, a through hole is opened on the inner side of the fixed plate 51, the spindle of the servo motor 52 is embedded in the through hole of the fixed plate 51, one end of the hollow cylinder 61 is embedded in the through hole of the servo motor 52, the outer side of the hollow cylinder 61 is fixedly connected to the inner side of the ball bearing 53, and the connecting port 64 is offset from the inner side of the ball bearing 53. There are two fixed plates 51 and two ball bearings 53. Through the above settings, the stability and accuracy of each component during the coating process are ensured. At the same time, by setting two fixed plates 51 and two ball bearings 53, the symmetry and balance of the coating process are achieved, and the uniformity and quality of the coating are improved. As a further implementation of this solution, the inner side of the airbag 62 is hollow, the inner side of the hollow cylinder 61 is hollow, the inner side of the hollow cylinder 61, the air vents 65 and the inner side of the airbag 62 are connected, multiple air vents 65 are located inside the airbag 62, the column block 67 is cylindrical, the outer side of the sealing rubber ring 68 is fitted with the inner side of the hollow cylinder 61, and a gap is provided between the column block 67 and the air vents 65. Through the above settings, the hollow structure and the connected design allow internal gas flow, realize pressure regulation, thereby adapting to coated objects of different thicknesses, preventing damage caused by excessive compression, improving the safety and adaptability of coating, and extending the service life of the equipment; Workflow: When laminating objects with curved surfaces, the curved object is placed at the top of the conveyor 2 and the bottom of the airbag 62. The end of the brightness-enhancing composite film roll, located on the outside of the material roller 4, is placed at the top of the brightness-enhancing composite film. Then, the brightness-enhancing composite film and the object are moved to the bottom of the airbag 62, ensuring that the brightness-enhancing composite film is in close contact with the airbag 62. The drive motor and servo motor 52 of the conveyor 2 are started, and the conveyor 2 transports the curved object. The servo motor 52 drives the hollow cylinder 61 to rotate. The dynamic connection is located inside the ball bearing 53. The ball bearing 53 reduces friction when the hollow cylinder 61 rotates. The rotation of the hollow cylinder 61 drives the airbag 62 to rotate. During the rotation of the airbag 62, it undergoes a certain deformation. Under the expansion force of the airbag 62, the gloss-enhancing composite film is compressed. At the same time, the shape of the airbag 62 changes with the shape of the curved object surface, thereby improving the uniformity of the contact force between the gloss-enhancing composite film and the curved object, avoiding localized instability, and improving the coating effect. Regarding the effectiveness and quality, during this process, when the airbag 62 deforms along with the curved object, if the thickness of the curved object is greater, the degree of compression on the airbag 62 will be greater. Excessive compression can easily cause the airbag 62 to burst. Therefore, it is necessary to appropriately change the internal pressure of the airbag 62 to improve the safety of the coating and the service life of the airbag 62. The gas inside the airbag 62 will enter the interior of the hollow cylinder 61 through the air outlet 65. At this time, the air pressure between the two pillars 67 will increase, and the gas will push... Under the action of movement, for example, the right end block 67 moves towards the right end spring 66, and the connecting port 64 can discharge the gas in the hollow cylinder 61 near the inside of the spring 66. This plays a role in relieving pressure inside the airbag 62 and preventing the airbag 62 from bursting. When the thickness of the curved object is thin, under the action of the elastic thrust of the spring 66, the block 67 pushes the gas between the two blocks 67 from the air outlet 65 into the airbag 62, keeping the airbag 62 inflated, thereby increasing the squeezing force of the airbag 62 on the light-enhancing composite film.
[0018] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
