Description

Technical Field

[0001] This utility model relates to the field of laminating machine technology, and in particular to a flexible packaging laminating adhesive laminating mechanism. Background Technology

[0002] Laminating machine technology combines film and substrate through adhesive application, drying, and hot pressing processes to form a paper-plastic composite product. This enhances the gloss, abrasion resistance, and moisture and water resistance of printed materials. Over the past few decades, laminating machine technology has evolved from traditional on-the-fly coating to environmentally friendly pre-coating and cold lamination processes. Flexible packaging laminating adhesive laminating mechanisms represent an innovative breakthrough in this field. By precisely controlling the amount of adhesive applied and the hot pressing parameters, they achieve efficient lamination of flexible packaging materials such as plastic film and aluminum foil, significantly improving the moisture resistance, barrier properties, and appearance of packaging products.

[0003] When high-barrier, wear-resistant, and environmentally friendly composite lamination is required for flexible packaging materials of food, pharmaceuticals, and daily chemicals to extend product shelf life and enhance packaging aesthetics, a flexible packaging lamination adhesive lamination machine is necessary. This machine is an automated device specifically designed for flexible packaging materials. Its core function is to uniformly apply lamination adhesive to the substrate surface through a precision control system, and then laminate it with another thin film through heating and pressurization processes, forming a composite packaging structure with high barrier properties, wear resistance, moisture and dirt resistance, and aesthetic appeal. However, most existing machines use fixed-distance scrapers, making it impossible to adjust the distance between the scraper and the coating roller. This results in an inability to adapt to various scenarios, loss of adhesive layer precision, low production flexibility, and easy damage to the substrate, reducing practicality.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0031] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3 This utility model provides an embodiment of a flexible packaging film coating mechanism, including a workbench 1, a base 3 fixedly connected to the front side of the workbench 1, a motor 4 fixedly connected to the top of the base 3, a rotating shaft 5 fixedly connected to the output end of the motor 4, a rotating plate 6 fixedly connected to the outer wall of the rotating shaft 5, a moving column 7 fixedly connected to the right side of the inner wall of the rotating plate 6, a rotating plate 8 rotatably connected to the outer wall of the moving column 7, a moving column 9 fixedly connected to the right side of the inner wall of the rotating plate 8, a fixed seat 10 fixedly connected to the outer wall of the moving column 9, a blade 11 fixedly connected to the left side of the fixed seat 10, an adhesive applicator 12 fixedly connected to the top of the workbench 1, a guide groove 13 provided on the inner wall of the adhesive applicator 12, and a cleaning mechanism 2 fixedly connected to the top left side of the workbench 1. The cleaning mechanism 2 is used to clean the substrate.

[0032] Specifically, the workbench 1 serves as the basic support platform for the entire mechanism, providing a stable installation position for other components and ensuring the stability of each component during operation. A base 3 is fixedly connected to the front of the workbench 1. The base 3 has good load-bearing capacity and stability, providing reliable support for the motor 4. The motor 4, model Y100L1-4, serves as the power source for the entire mechanism and is installed on top of the base 3. The output end of the motor 4 is fixedly connected to the rotating shaft 5. When the motor 4 starts, its rotational power is transmitted to the rotating shaft 5 through the output end, causing the rotating shaft 5 to rotate. A rotating plate 6 is fixedly connected to the outer wall of the rotating shaft 5, and the rotating plate 6 can rotate with the rotating shaft 5. A movable column 7 is fixedly connected to the right side of the inner wall of the movable column 7. A rotating plate 8 is rotatably connected to the outer wall of the movable column 7, and the rotating plate 8 can rotate and move under the drive of the movable column 7. The rotating plate 8 has a composite motion. On the right side of the inner wall of the rotating plate 8, a movable column 9 is fixedly connected. The design of the movable column 9 allows the motion of the rotating plate 8 to be further transmitted. A fixed seat 10 is fixedly connected to the outer wall of the movable column 9. The fixed seat 10 plays a role in stabilization and connection, providing a reliable installation position for the blade 11. The blade 11 is fixedly connected to the left side of the fixed seat 10 to achieve precise glue scraping operation. A glue applicator 12 is fixedly connected to the top of the worktable 1. The glue applicator 12 can stably support and fix other related components. The inner wall of the glue applicator 12 has a guide groove 13. The size of the guide groove 13 matches the movable column 9. When the movable column 9 moves under the drive of the rotating plate 8, under the restriction of the guide groove 13, the movable column 9 can only move horizontally along the direction of the guide groove 13. This design allows the blade 11 to be precisely adjusted in the horizontal direction.

[0033] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3 The cleaning mechanism 2 includes a fixed plate 201. The bottom of the fixed plate 201 is fixedly connected to the top left side of the workbench 1. A sliding groove 202 is provided on the inner wall of the fixed plate 201. Multiple sliding plates 206 are slidably connected to the inner wall of the sliding groove 202. A cleaning plate 207 is fixedly connected to the bottom of the sliding plate 206. Limiting plates 208 are fixedly connected to the front and rear sides of the sliding plate 206. Multiple slots 203 are provided on the right side of the inner wall of the sliding groove 202. A positioning hole 204 is provided on the inner wall of the slot 203. A positioning post 205 is slidably connected to the inner wall of the positioning hole 204.

[0034] Specifically, the fixed plate 201, as the core support component of the cleaning mechanism 2, is fixedly connected to the top left side of the workbench 1 at its bottom. A groove 202 is formed on the inner wall of the fixed plate 201. The groove 202 ensures that the sliding plate 206 can slide smoothly within it while maintaining a certain stability, preventing deviation or jamming. Multiple sliding plates 206 are slidably connected to the inner wall of the groove 202, allowing for flexible position adjustment according to different substrate specifications and cleaning needs. A cleaning plate 207 is fixedly connected to the bottom of the sliding plate 206. The cleaning plate 207 is the component that directly contacts the substrate surface for cleaning. To ensure that the sliding plate 206 does not deviate from the track when sliding within the groove 202, limit plates 208 are fixedly connected to both the front and rear sides of the sliding plate 206. The limit plates 208 restrict the sliding range of the sliding plate 206. The right side of the inner wall of the groove 202... Multiple slots 203 are provided, offering multiple fixed positions for the sliding plate 206. When the sliding plate 206 slides to a suitable height, i.e., when the cleaning plate 207 reaches the optimal cleaning distance from the substrate surface, the sliding plate 206 can be moved to the right to engage with the corresponding slot 203, achieving initial positioning and fixation. Each slot 203 also has a positioning hole 204 on its inner wall, which matches a positioning post 205. After the sliding plate 206 engages with the slot 203, the positioning post 205 is inserted into the positioning hole 204. Simultaneously, the positioning post 205 is also inserted into a pre-set hole on the sliding plate 206, achieving double fixation. This double fixation method greatly enhances the stability of the sliding plate 206, ensuring that the cleaning plate 207 will not shift due to external forces during the cleaning process, thus guaranteeing the stability and reliability of the cleaning effect.

[0035] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 5 A heating box 19 is fixedly connected to the top right side of the workbench 1. A vertical plate 20 is fixedly connected to the top of the workbench 1 near the edge. A bearing 21 is fixedly connected to the front side of the vertical plate 20. A unwinding roller 22 is rotatably connected to the inner wall of the bearing 21. A glue-applying groove 14 is opened on the inner wall of the workbench 1. A partition 16 is fixedly connected to the right side of the inner wall of the glue-applying groove 14.

[0036] Specifically, the heating box 19 serves a heating function, the upright plate 20 serves a supporting function, the bearing 21 is used to support the rotation of the unwinding roller 22, the unwinding roller 22 is used for unwinding, the glue tank 14 is used to store the glue liquid, and the partition 16 serves a separating function.

[0037] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 4An overflow groove 15 is provided on the right side of the inner wall of the workbench 1. A pressure gauge 23 is fixedly connected to the front side of the glue applicator 12. An applicator roller 17 is rotatably connected to the inner wall of the glue applicator 12. A pressure roller 18 is rotatably connected to the top of the inner wall of the glue applicator 12. The inner wall of the guide groove 13 is slidably connected to the front end of the outer wall of the moving column 9. The rear end of the outer wall of the rotating shaft 5 is rotatably connected to the front side of the inner wall of the glue applicator 12.

[0038] Specifically, the overflow groove 15 serves to collect the overflowing adhesive, the pressure gauge 23 is used to display the pressure, the glue roller 17 is used to apply adhesive to the substrate, the pressure roller 18 is used to press the substrate, the movable column 2 9 can slide in the guide groove 13, and the rotating shaft 5 can rotate on the front side of the inner wall of the glue application frame 12.

[0039] Working principle: First, the motor 4 is started. The base 3 provides support for the motor 4, and the worktable 1 provides support for the base 3. The motor 4 drives the rotating shaft 5 to rotate, the rotating shaft 5 drives the rotating plate 6 to rotate, the rotating plate 6 drives the moving column 7 to move, the moving column 7 drives the rotating plate 8 to move while rotating around the moving column 7, the rotating plate 8 drives the moving column 9 to move, the moving column 9 moves horizontally under the restriction of the guide groove 13, the moving column 9 drives the fixed seat 10 to move, and the fixed seat 10 drives the blade 11 to move, thereby adjusting the distance between the scraper and the coating roller, greatly improving the adaptability of the scene, the precision and controllability of the adhesive layer, improving production efficiency, protecting the substrate, and improving practicality.

[0040] When the substrate moves from left to right, the upper and lower sides of the substrate come into contact with the cleaning plate 207, which cleans the surface of the substrate. The sliding plate 206 moves up and down, and moves under the restriction of the slide groove 202. The limiting plate 208 prevents the sliding plate 206 from falling out of the slide groove 202. After moving to a suitable height, the sliding plate 206 is moved into the slot 203. The fixing plate 201 provides a fixed position for the slide groove 202 and the slot 203. Then, the positioning post 205 is inserted into the positioning hole 204. The positioning post 205 is also inserted into the inner wall of the sliding plate 206, thereby fixing the sliding plate 206. By adjusting the distance between the upper and lower cleaning plates 207, the substrate is cleaned, and both sides of the substrate are cleaned, improving the coating adhesion quality and increasing practicality.
