Description

Technical Field

[0001] This utility model belongs to the technical field of gluing mechanism, and in particular relates to a gluing mechanism for processing high-barrier composite films. Background Technology

[0002] In modern industrial production, especially in the field of high-barrier composite film manufacturing, the requirements for adhesive application processes are becoming increasingly stringent and sophisticated.

[0003] Traditional gluing devices often face numerous limitations and struggle to meet diverse production demands. When processing composite films of varying thicknesses, conventional fixed roller layouts cannot adapt to changes in film thickness. Consequently, operators must frequently and manually adjust various parameters of the gluing device, including roller spacing and pressure, to ensure that the composite film surface can fully and evenly contact the coating rollers for optimal gluing results. However, each adjustment requires machine downtime, significantly increasing downtime, disrupting continuous production processes, and leading to decreased overall capacity and increased production costs. Therefore, a gluing mechanism for processing high-barrier composite films is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a coating mechanism for processing high-barrier composite films. Specifically, the composite film is introduced into the gap between the lifting roller and the coating roller via a guide roller. Initially, the two rollers are in contact. After the film passes through, the lifting roller is pressed down, and the linkage bracket slides along the slide bar, compressing the spring to store energy. The spring, constrained by the fixed seat, rebounds and resets, driving the lifting roller to rise and push the composite film, ensuring it remains in contact with the coating roller. This structure adapts to film materials of different thicknesses, solving the problem that conventional fixed roller layouts cannot adapt to changes in composite film thickness. This previously required operators to frequently manually adjust various parameters of the coating device, including roller spacing and pressure, to ensure sufficient and uniform contact between the composite film surface and the coating roller for good coating results. However, each adjustment required machine shutdown, significantly increasing downtime, disrupting continuous production, and leading to decreased overall capacity and increased production costs.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to an adhesive application mechanism for processing high-barrier composite films, including a base, which serves as a stable support foundation for the entire device, and further comprising: The gluing mechanism is located above the base. The gluing mechanism maintains the continuity and stability of production by adjusting the tension and adaptive gluing. The gluing mechanism includes a coating component, which includes a lifting roller. A gluing roller is positioned above the lifting roller, and brackets are connected to both the front and back of the internal pin of the lifting roller.

[0006] Furthermore, the adhesive application mechanism also includes: An adjustment component, disposed on the left side of the coating component, is used to adjust the tension of the composite film during transport; and A conveying assembly is disposed above the base and is used to guide and convey the composite film. The base has several support rods welded to its top, and a support frame is welded to the top of each support rod.

The inside of the glue application roller is connected to the glue outlet at the bottom of the glue storage tank through a pin. The bottom of the guide roller is at the same horizontal level as the bottom of the coating roller.

[0008] Furthermore, slide rods are slidably connected to the left and right sides inside the two brackets. The four slide rods are arranged in pairs. The two sets of slide rods pass through the brackets and extend to the top and bottom. Springs are sleeved on the outer surface of the two sets of slide rods.

The fixed seats are welded to the bottom of the slide rods. The sides of the two sets of fixed seats are welded to the sides of the support rods. Both sets of slide rods have a protruding edge at the top that is larger than their own diameter.

[0009] Furthermore, the adjustment assembly includes an electric push rod mounted on the top of the base, with a telescopic rod connected to the top output end of the electric push rod, and a support frame connected to the side of the telescopic rod away from the electric push rod.

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.

[0019] Please see Figures 1-5As shown, this utility model is a gluing mechanism for processing high-barrier composite films. It includes a base 111, which serves as a stable support for the entire device. It also includes a gluing mechanism 2, positioned above the base 111. The gluing mechanism 2 maintains production continuity and stability through tension adjustment and adaptive gluing. The gluing mechanism 2 includes a coating assembly 21, which includes a lifting roller 212. A coating roller 213 is positioned above the lifting roller 212. Supports 215 are connected to the front and back of the internal pin of the lifting roller 212. The gluing mechanism 2 also includes an adjustment assembly 22, positioned to the left of the coating assembly 21. The adjustment assembly 22 is used to adjust the tension of the composite film during transport. In addition, a conveying assembly 23 is disposed above the base 111 and is used to guide and convey the composite film. Several support rods 112 are welded to the top of the base 111, and support frames 113 are welded to the top of the support rods 112. A glue storage tank 211 is disposed above the lifting roller 212. The front and back of the glue storage tank 211 are connected to the corresponding sides of the support rods 112. A guide roller 214 is disposed on the left side of the glue storage tank 211. The interior of the guide roller 214 is connected to the interior of the support rod 112 via a pin. The interior of the coating roller 213 is connected to the glue outlet at the bottom of the glue storage tank 211 via a pin. The bottom of the guide roller 214 and the bottom of the coating roller 213 are at the same horizontal line. The left and right sides of the two supports 215 are also present. Each of the four slide rods 216 is slidably connected, with two slide rods 216 arranged in groups of two. Both groups of slide rods 216 pass through the bracket 215 and extend to the top and bottom. Springs 217 are fitted onto the outer surface of each group of slide rods 216. The tops of both springs 217 are connected to the bottom of the bracket 215. A fixing seat 218 is connected to the side of each spring 217 away from the bracket 215. Both fixing seats 218 are welded to the bottom of the slide rod 216, and the sides of both fixing seats 218 are welded to the sides of the support rod 112. The tops of both slide rods 216 have a protruding edge larger than their own diameter. The composite film is introduced into the gap between the lifting roller 212 and the coating roller 213 via the guide roller 214. Initially, the two rollers are in contact. After the film passes through, the lifting roller 212 is pressed down, and the bracket 215 is activated. The slide bar 216 slides along the spring 217 to store energy. The spring 217 is restrained by the fixed seat 218 and rebounds to reset, driving the lifting roller 212 to rise and push the composite film, so that it continuously adheres to the coating roller 213. This structure adapts to different film thicknesses, eliminates the need for frequent equipment adjustments, reduces downtime, and improves production continuity, efficiency, and equipment versatility. The adjustment component 22 includes an electric push rod 221, which is mounted on the top of the base 111. The top output end of the electric push rod 221 is connected to a telescopic rod 222. A support frame 223 is connected to the side of the telescopic rod 222 away from the electric push rod 221. A tension roller 224 is connected inside the support frame 223 via a pin. Slider 225s are welded to both the front and back of the support frame 223.The front and back sides of the support frame 223 are in contact with the front and back sides of the inner wall of the support rod 112. The front and back sides of the inner wall of the support rod 112 are each provided with a groove 226. The interior of each groove 226 is slidably connected to the outer surface of the slider 225. Activating the electric push rod 221 drives the telescopic rod 222 to move up and down, causing the support frame 223 to move synchronously. Its external slider 225 slides along the groove 226 to stabilize the trajectory and, in conjunction with the tension roller 224 and guide roller 214, adjusts the tension of the composite film to ensure proper coating. The membrane material is stable and subjected to uniform force, resulting in consistent adhesive layer thickness and improved stability of the composite film's barrier performance. The conveying assembly 23 includes a take-up roller 231, which is connected to two support rods 112 on the right side. Two support rods 112 on the left side are connected to an unwind roller 232. Two guide rollers 233 are positioned to the right of the unwind roller 232. The interiors of the two guide rollers 233 are connected to the interiors of the support rods 112 via pins. The guide roller 233 on the left side is higher than the guide roller 233 on the right side.

[0020] A specific application of this embodiment is as follows: In use, the composite film on the unwinding roller 232 is first passed sequentially through the top and bottom of the two guide rollers 233, then through the top of the tension roller 224 to the bottom of the guide roller 214, and finally through the top of the lifting roller 212 and wound onto the surface of the take-up roller 231. Then, the take-up roller 231 is activated to wind up and apply adhesive to the composite film. During the adhesive application process, the operator can adjust the tension of the composite film. Specifically, the electric push rod 221 is activated to drive the telescopic rod 222 to move upward or downward. When the telescopic rod 222 moves, it will drive the support frame 223 to move together. At the same time, when the support frame 223 moves... During the process, the two sliders 225 will slide inside the groove 226. The sliders 225 provide a certain stability for the movement trajectory of the support frame 223 through the function of the groove 226. At the same time, when the support frame 223 moves, it will drive the tension roller 224 to move together. When the tension roller 224 moves, it will adjust the tension of the composite film through the function of the support frame 223 and the guide roller 214. This can improve the stability and consistent tension of the film material during the coating process, so that the adhesive can be evenly coated on the film surface, reducing the uneven thickness of the adhesive layer caused by uneven local tension, thereby improving the uniformity and stability of the barrier performance of the composite film. Meanwhile, during the subsequent coating of the composite film, the composite film, guided by guide roller 214, enters between lifting roller 212 and coating roller 213. Initially, the surface of lifting roller 212 is in contact with the surface of coating roller 213. After the composite film is inserted, lifting roller 212 moves downward under the action of force. During the movement of lifting roller 212, it drives the two supports 215 to move together. When the two supports 215 move, their interiors slide on the outer surface of slide bar 216. At the same time, the movement of supports 215 compresses spring 217, which is then limited by fixed seat 218. The position will contract and store force, while the spring 217 will generate a certain rebound force and drive the bracket 215 to reset. When the bracket 215 resets, it will drive the lifting roller 212 to move together. At this time, the lifting roller 212 will lift the composite film, so that the surface of the composite film is always in contact with the surface of the coating roller 213, thereby completing the coating effect on composite films of various thicknesses. This reduces the need to adjust the coating device due to different thicknesses, reduces the occurrence of time-consuming conditions in the production process, reduces downtime, improves production continuity and efficiency, and can adapt to film materials of various thicknesses, improving the versatility and flexibility of the equipment.
