Description

Technical Field

[0001] This utility model relates to the technical field of hot roller coating machines, specifically a hot roller rapid coating machine. Background Technology

[0002] A hot roller laminating machine is a device used for surface treatment of printed materials. It primarily uses heated rollers to rapidly bond plastic films (such as BOPP, PET, etc.) to the surface of paper or other substrates under high temperature and pressure, forming a smooth, waterproof, and wear-resistant protective layer. Its core components include heated rollers, pressure rollers, and unwinding and rewinding devices. It features efficient and uniform lamination, making it suitable for post-printing processing of brochures, packaging, posters, etc., and significantly improving the texture and durability of printed materials.

[0003] Traditional hot-pressing methods rely heavily on cold pressing or manual lamination, which not only requires longer pressing times but also struggles to achieve rapid and stable material lamination, resulting in low overall efficiency when dealing with batch lamination demands. In such cases, material is prone to wrinkling and shifting during conveying and pressing due to speed mismatches, affecting lamination quality and failing to meet the requirements of efficient and continuous production. Therefore, we propose a hot roller rapid laminating machine. Utility Model Content

[0004] The purpose of this invention is to provide a hot roller rapid laminating machine to solve the problems mentioned in the background art, where the hot pressing method of traditional devices relies heavily on cold pressing or manual lamination. This not only requires a longer pressing time but also makes it difficult to achieve rapid and stable material lamination, resulting in low overall efficiency when facing batch lamination needs. In this case, the material is prone to wrinkles and displacement during the conveying and pressing process due to speed mismatch, affecting the lamination quality and making it difficult to meet the needs of efficient and continuous production.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a hot roller rapid laminating machine, comprising: a laminating machine body, a conveyor frame fixedly connected to the side surface of the laminating machine body, and a cutting component provided on the side surface of the conveyor frame;

[0023] 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.

[0024] Please see Figure 1-6 This utility model provides a technical solution: a hot roller rapid coating machine, including: a coating machine body 1, a conveyor frame 2 fixedly connected to the side surface of the coating machine body 1, and a cutting component 3 provided on the side surface of the conveyor frame 2.

[0025] In use, the hot press roller group 15 is driven by the drive component 11, and the first feeding frame 13 on the support frame 12 and the second feeding frame 14 outside the drive component 11 are used to realize the synchronous conveying of the film coating material and the substrate to be coated. The hot roller pressing replaces the traditional cold pressing or manual bonding, realizing continuous film coating, greatly shortening the time for a single batch, and significantly improving the work efficiency.

[0026] The laminating machine body 1 includes a drive assembly 11, a support frame 12 is fixedly connected to the upper surface of the drive assembly 11, a first feeding frame 13 is movably connected to the side surface of the support frame 12, a second feeding frame 14 is movably connected to the outer surface of the drive assembly 11, and a hot press roller group 15 is provided inside the drive assembly 11.

[0027] The cutting assembly 3 includes a fixing plate 31 and a guide top plate 36. The upper surface of the guide top plate 36 is provided with a first sliding groove 37, and the interior of the guide top plate 36 is provided with a second sliding groove 38. A limiting plate 39 is fixedly connected to the upper surface of the first sliding groove 37. A connecting post 311 is fixedly connected to the bottom of the limiting plate 39. A limiting block 312 is fixedly connected to the end of the connecting post 311 away from the limiting plate 39. A first limiting buckle 314 is fixedly connected to the side surface of the limiting block 312. A spring post 315 is sleeved on the end of the first limiting buckle 314 away from the limiting block 312. A second limiting buckle 316 is sleeved on the outer surface of the spring post 315. The side of the second limiting buckle 316 away from the spring post 315 is fixedly connected to the inner wall of the guide top plate 36.

[0028] A fixing bolt 32 is movably connected to the outer surface of the fixing plate 31, and a connecting plate 33 is fixedly connected to the outer surface of the fixing plate 31. The fixing plate 31 is movably connected to the left and right sides of the conveyor frame 2. A positioning plate 34 is fixedly connected to the side of the connecting plate 33 away from the fixing plate 31. A guide bottom plate 35 is fixedly connected to the outer surface of the positioning plate 34, and the guide bottom plate 35 is fixedly connected to the bottom of the guide top plate 36. A cutting knife 313 is fixedly connected to the bottom of the limiting block 312, and the limiting block 312 is slidably connected to the inner surface of the second slide groove 38. The second limiting buckle 316 and the first limiting buckle 314 are respectively sleeved on both ends of the spring column 315, and the spring column 315 is movably connected to the inner surface of the second slide groove 38. A push block 310 is fixedly connected to the upper surface of the limiting plate 39, and anti-slip grooves 317 are provided on both sides of the push block 310.

[0029] When using this hot roller rapid laminating machine, the drive assembly 11 first drives the hot press roller group 15 to run. The first feeding frame 13 on the support frame 12 and the second feeding frame 14 outside the drive assembly 11 realize the synchronous conveying of the laminating material and the substrate to be laminated. The hot press roller group 15 replaces the traditional cold pressing or manual lamination by hot roller pressing, which greatly shortens the laminating time for a single batch and can complete continuous laminating without repeated operations, significantly improving the overall work efficiency.

[0030] The cutting assembly 3 is connected to the conveyor frame 2 via a fixing plate 31. The operator tightens the fixing bolts 32 on the outer surface of the fixing plate 31, firmly securing it to both sides of the conveyor frame 2 to prevent displacement of the assembly due to vibration or force during the cutting process. The connecting plate 33 on the outer surface of the fixing plate 31 is fixedly connected to the positioning plate 34, which in turn is connected to the guide base plate 35. The guide base plate 35 is fixed to the bottom of the guide top plate 36, forming a stable support frame and providing a stable foundation for the cutting action.

[0031] When the laminating machine 1 completes the laminating process, the laminated material is conveyed by the conveyor frame 2 to the cutting assembly 3. The operator then initiates the cutting process using the push block 310. Anti-slip grooves 317 on both sides of the push block 310 increase hand friction and prevent slippage during operation. The push block 310 is fixed to the upper surface of the limiting plate 39. When the push block 310 is pushed, the limiting plate 39 slides horizontally along the first groove 37 on the upper surface of the guide plate 36, simultaneously moving the connecting column 311 at the bottom. The lower end of the connecting column 311 is fixedly connected to the limiting block 312, which is slidably connected within the second groove 38 inside the guide plate 36. Therefore, the limiting block 312 slides stably along the second groove 38 with the connecting column 311, ensuring the straightness of the movement trajectory. The cutting blade 313 at the bottom of the limiting block 312 moves synchronously with it, contacting the conveyed laminating material to complete the cutting. At this time, the first limiting buckle 314 on the side surface of the limiting block 312 compresses the sleeved spring post 315, and the other end of the spring post 315 is sleeved in the second limiting buckle 316 fixed to the inner wall of the guide top plate 36. When the spring post 315 is compressed, it stores elastic potential energy, buffers the impact force at the moment of cutting, avoids damage to the cutting knife 313 due to rigid collision, and at the same time makes the cutting force more uniform, ensuring a flat cut. After the cutting is completed, the operator releases the push block 310, and the compressed spring post 315 releases elastic potential energy, pushing the limiting block 312 in the opposite direction through the first limiting buckle 314, causing the connecting post 311, the limiting plate 39 and the push block 310 to reset along the first slide groove 37 and the second slide groove 38, returning to the initial position, ready for the next cutting.
