Description

Technical Field

[0001] This utility model relates to the field of paper packaging technology, and in particular to a gluing device for a laminating machine. Background Technology

[0002] In industries such as packaging, printing, and paper processing, laminating machines are key equipment for composite processing of substrates (such as paper, film, and board). The gluing device, as a core component, directly determines the bonding strength and surface quality of the composite substrates. As the industry's requirements for the precision of composite products continue to increase, the gluing device needs to ensure uniform application and stable delivery of glue while also taking into account the convenience of equipment maintenance to meet the needs of efficient operation in continuous production scenarios. Its performance optimization is of great significance for improving the overall processing efficiency and product qualification rate of the production line.

[0003] Existing gluing devices for laminating machines typically consist of three core parts: a glue storage mechanism, a glue coating mechanism, and a glue scraping mechanism. The glue storage mechanism is usually an open or semi-open tank used to store the glue required for gluing. The glue coating mechanism drives the glue coating roller to rotate via a motor, so that the surface of the glue coating roller is evenly absorbed with glue and then transferred to the surface of the substrate. The glue scraping mechanism is located on one side of the glue coating roller. It forms a specific gap with the surface of the glue coating roller through a fixed scraper, and scrapes off and controls the glue thickness on the glue coating roller to ensure that the amount of glue on the substrate surface meets the processing requirements. The entire device achieves continuous gluing processing of the substrate through the coordinated operation of each mechanism.

[0004] However, in practical applications, the scraper mechanism of the existing laminating machine's gluing device is mostly installed by bolting, welding, or complex snap-fit ​​connections between the scraper and the main body of the device. After the gluing work is completed, the glue residue on the scraper surface needs to be cleaned regularly to ensure the accuracy of subsequent scraping. However, since the disassembly process requires the use of special tools to disassemble the fixed parts one by one, or to break through the limits of complex snap-fits, the scraper disassembly operation is cumbersome and time-consuming. This not only increases the maintenance workload of the staff, but may also affect the continuous operation efficiency of the production line due to long-term downtime. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a gluing device for a laminating machine, which aims to improve the problem of cumbersome and time-consuming disassembly process during scraper cleaning in existing gluing devices for laminating machines.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a gluing device for a laminating machine, comprising a fixed scraper, wherein a quick-release component is provided inside the fixed scraper, a glue storage tank is provided above the fixed scraper, and a stirring component is provided inside the glue storage tank; The quick-release assembly includes a positioning ring, the outer wall of which is fixedly connected to the inside of the fixed scraper. A spring is fixedly connected to one end of the positioning ring, a sliding protrusion is fixedly connected to one end of the spring, and the other end of the spring is fixedly connected to one end of the positioning ring. An extension handle is fixedly connected to the outer wall of the sliding protrusion. A movable slot is provided inside the fixed scraper. The outer wall of the extension handle is slidably connected to the inner wall of the movable slot. A slide rail is slidably connected to the outer wall of the sliding protrusion. A mounting base is slidably connected to the outer wall of the sliding protrusion. An arc-shaped baffle is fixedly connected to the inner wall of the slide rail. Limiting slots are provided inside both the mounting base and the slide rail.

[0007] Furthermore, the stirring assembly includes a motor, which is disposed on one side of the outer wall of the glue storage tank. A stirring shaft is fixedly connected to the output end of the motor, and a spiral blade is fixedly connected to the outer wall of the stirring shaft. Multiple strip blades are also fixedly connected to the outer wall of the stirring shaft.

[0008] Furthermore, a cover plate is provided on the upper surface of the glue storage tank, and two handles are fixedly connected to the upper surface of the cover plate.

[0009] Furthermore, a workbench is provided below the fixed scraper, and both ends of the fixed scraper are set on the inner wall of the mounting base.

[0010] Furthermore, each of the two mounting bases is fixedly connected to a support rod, and the lower surface of the support rod is fixedly connected to the upper surface of the support frame.

[0011] Furthermore, a motor is provided above the workbench, and the motor is located below the fixed scraper.

[0012] Furthermore, a glue delivery pipe is fixedly connected to the inner wall of the glue storage tank, a glue box is provided below the glue delivery pipe, the inner wall of the glue box is set on the outer wall of the fixed scraper, and a rubber sealing ring is fixedly connected to the outer wall of the glue delivery pipe.

[0013] Furthermore, the adhesive box is located below the motor.

[0014] This utility model has the following beneficial effects: 1. In this utility model, after the gluing work is completed, the residual glue on the fixed scraper needs to be cleaned. The worker moves the extended handle to the right along the movable slot, which drives the sliding protrusion to squeeze the spring back. The sliding protrusion disengages from the limiting slot between the mounting base and the slide rail, and the fixed scraper can be removed by moving it upward along the slide rail. This simplifies the disassembly process and solves the problem of cumbersome and time-consuming disassembly of traditional scrapers. When installing the fixed scraper, the arc-shaped baffle works with the mounting base to limit the fixed scraper and prevent the scraper from shifting during the gluing process, which would result in uneven glue thickness on the substrate.

[0015] 2. In this utility model, when the glue in the storage tank precipitates and separates due to settling, the motor is turned on to drive the stirring shaft to rotate, which in turn drives the spiral blades and strip blades to rotate synchronously. The two work together to achieve uniform mixing of the glue in the entire tank, effectively solving the problem of uneven glue thickness caused by glue separation and ensuring stable glue application quality on the substrate. At the same time, when the glue in the storage tank is insufficient, the operator can quickly open the cover plate through the handle to add glue. During the glue addition process, the stirring component can continue to operate to ensure that the new glue and the original glue are quickly integrated without interrupting the glue application process. Moreover, the cover plate can isolate external dust and prevent impurities from contaminating the glue, further maintaining the cleanliness of the glue and the glue application effect.

[0018] 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.

[0019] Reference Figures 1-6The present invention provides an embodiment of a glue application device for a laminating machine, comprising a fixed scraper 12, a quick-release assembly inside the fixed scraper 12, a glue storage tank 6 above the fixed scraper 12, and a stirring assembly inside the glue storage tank 6. The quick-release assembly includes a positioning ring 17, whose outer wall is fixedly connected to the inside of the fixed scraper 12. A spring 18 is fixedly connected to one end of the positioning ring 17, and a sliding protrusion 19 is fixedly connected to one end of the spring 18. The other end of the spring 18 is fixedly connected to one end of the positioning ring 17. The spring 18 provides elastic driving force to realize the automatic reset and locking of the sliding protrusion 19. An extension handle 20 is fixedly connected to the outer wall of the sliding protrusion 19. A movable slot 21 is opened inside the fixed scraper 12. The outer wall of the extension handle 20 is slidably connected to the inner wall of the movable slot 21. The operator only needs to hold the extension handle 20 and move it along the right side of the movable slot 21. The sliding protrusion 19 can be driven by the force transmitted by the extended handle 20 to compress the spring 18, thereby unlocking. The outer wall of the sliding protrusion 19 is slidably connected to a slide rail 13 that provides vertical movement guidance. The outer wall of the sliding protrusion 19 is slidably connected to a mounting base 2. The inner wall of the slide rail 13 is fixedly connected to an arc-shaped baffle 14. The arc-shaped baffle 14 and the slide rail 13 cooperate to achieve double limiting of the fixed scraper 12. The mounting base 2 and the slide rail 13 are both provided with limiting slots 15. The limiting slots 15 are precisely matched with the sliding protrusion 19. When the fixed scraper 12 is installed in place, the sliding protrusion 19 is embedded into the limiting slot 15 under the elastic force of the spring 18.

[0020] Specifically, after the glue application is completed, the residual glue on the fixed scraper 12 needs to be cleaned. Move the extension handle 20 to the right along the movable slot 21, which will cause the sliding protrusion 19 to squeeze the spring 18 and retract until the sliding protrusion 19 disengages from the limiting slot 15 between the mounting base 2 and the slide rail 13. At this time, move the fixed scraper 12 upward along the slide rail 13 to disassemble and clean it. When installing the fixed scraper 12, the arc-shaped baffle 14 can provide limiting support to ensure accurate installation. The arc-shaped baffle 14 and the glue box 16 can jointly support the fixed scraper 12, which limits and fixes the fixed scraper 12 during the glue application process.

[0021] Reference Figures 1-6The mixing assembly includes a motor 9 that provides driving force. The motor 9 is located on one side of the outer wall of the glue storage tank 6. A stirring shaft 10 is fixedly connected to the output end of the motor 9, driving the stirring shaft 10 to rotate. Spiral blades 11 are fixedly connected to the outer wall of the stirring shaft 10. The spiral blades 11 handle the glue at one end longitudinally, preventing glue sedimentation at the bottom of the glue storage tank 6. Multiple strip blades 23 are fixedly connected to the outer wall of the stirring shaft 10. The transverse rotation of the strip blades 23 disperses and stirs the upper layer of glue in the glue storage tank 6. Together with the spiral blades 11, this achieves comprehensive glue mixing and improves the uniformity of mixing. A cover plate 5 is provided on the upper surface of the glue storage tank 6 to prevent dust and volatilization, ensuring that the mixing assembly operates in a clean environment. Two handles 7 are fixedly connected to the upper surface of the cover plate 5. A worktable is provided below the fixed scraper 12. 1. The fixed scraper 12 is mounted on the inner wall of the mounting base 2 at both ends. Support rods 3 are fixedly connected inside the two mounting bases 2. The lower surface of the support rods 3 is fixedly connected to the upper surface of the support frame 4 to ensure the stability of the support frame 4 and the glue storage tank 6. A motor 9 is installed above the workbench 1. The motor 9 is located above the fixed scraper 12. A glue delivery pipe 8 is fixedly connected to the inner wall of the glue storage tank 6. A glue box 16 is located below the glue delivery pipe 8. The glue delivery pipe 8 delivers the glue in the glue storage tank 6 to the glue box 16. The inner wall of the glue box 16 is set on the outer wall of the fixed scraper 12. The fixed scraper 12 scrapes away the excess glue from the glue application roller. The excess glue flows into the glue box 16. A rubber sealing ring 22 is fixedly connected to the outer wall of the glue delivery pipe 8 to prevent the glue from leaking during the delivery of glue from the glue storage tank 6. The glue box 16 is located below the motor 9.

[0022] Specifically, during glue application, the glue in the glue storage tank 6 is prone to sedimentation and stratification. The motor 9 is turned on, driving the stirring shaft 10 to rotate. The stirring shaft 10 then drives the spiral blade 11 and the fixed scraper 12 to move synchronously. Through the stirring of the spiral blade 11 and the assistance of the fixed scraper 12, the glue stratification is broken, ensuring the glue is uniform and ensuring the glue application quality. When the glue in the glue storage tank 6 is insufficient, the cover plate 5 can be opened to add glue directly. The cover plate 5 can also isolate external dust, preventing dust from entering the glue storage tank 6 and contaminating the glue, ensuring the cleanliness of the glue and maintaining a stable glue application effect.

[0023] Working principle: When this equipment is needed, the substrate is placed into the motor 9, and after passing through the pressure roller and the glue coating roller, the substrate is glued. First, during the glue application process, the glue in the glue storage tank 6 may settle and separate. Turning on the motor 9 drives the stirring shaft 10 and the spiral blades 11 on the outer wall of the stirring shaft 10 and the fixed scraper 12 to move synchronously, preventing the glue in the glue storage tank 6 from separating. If the glue runs out, the cover plate 5 can be opened to add more glue. The cover plate 5 prevents dust from entering. Second, after the glue application is complete, residue will remain on the fixed scraper 12. If glue residue remains, it needs to be cleaned. Move the extension handle 20 to the right along the movable slot 21. The extension handle 20 drives the sliding protrusion 19 to retract through the compression spring 18 until the sliding protrusion 19 disengages from the limiting slot 15 inside the mounting base 2 and the slide rail 13. Then, move the fixed scraper 12 upward along the slide rail 13. The fixed scraper 12 can be disassembled and cleaned through the slide rail 13. The arc-shaped baffle 14 limits the fixed scraper 12 again during installation and supports the fixed scraper 12 together with the glue box 16.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
