Technical Field
[0001] This utility model relates to the field of film-coating packaging machine technology, and in particular to an automatic film-coating packaging machine. Background Technology
[0002] With the continuous improvement of modern industrial automation, the packaging industry's demand for efficient, precise, and multifunctional laminating equipment is growing. Automatic laminating and packaging machines, as one of the core pieces of equipment in packaging production lines, are widely used in food, pharmaceuticals, daily chemicals, and electronic products, and their performance directly affects packaging efficiency and finished product quality. Currently, mainstream laminating equipment generally adopts mechanical tension adjustment and fixed laminating structures. However, in actual production, due to the diverse sizes of packaged goods, significant differences in film materials, and frequent production changes, traditional equipment is gradually revealing technical bottlenecks such as limited adjustment range, high operational complexity, and poor adaptability. Especially in small-batch, multi-variety production models, existing equipment struggles to balance adjustment accuracy and changeover efficiency, becoming a key factor restricting the flexibility of packaging production lines.
[0003] In existing technologies, traditional tensioning mechanisms use fixed-stroke hydraulic cylinders, resulting in a narrow range of film tension adjustment. This makes them unsuitable for tension control of ultra-thin or highly elastic films, easily leading to film relaxation or breakage. Existing laminating assemblies mostly achieve pressure adjustment through cylinders or motors, but lack fine-tuning mechanisms. This results in coarse pressure control for irregularly shaped parts (such as curved glass) or thin-walled parts (such as ceramic products), easily causing indentations or bubble defects. Traditional equipment requires disassembling multiple fixing bolts and recalibrating transmission components when changing film rolls or adjusting packaging dimensions. This long changeover time severely impacts production efficiency and practicality. Therefore, this utility model discloses an automatic laminating and packaging machine to solve the problems of limited film tension adjustment and adjustment range in existing technologies.

[0014] The beneficial effects of this utility model are:
[0015] This invention significantly improves the ability to adjust film tension and adapt to the laminating needs of items of different sizes through a tension adjustment component and an adjusting laminating component. It offers multiple benefits, including an expanded tension adjustment range, enhanced ease of operation, strong adaptability, reduced maintenance costs, and increased production efficiency. Specifically, the tension adjustment component employs a structure of a vertical guide rod and a sliding shaft combined with a vertical spring. This allows the adjusting roller to slide flexibly up and down within the vertical sliding groove according to the film tension and requirements. This not only effectively expands the film tension adjustment range but also adapts to films of different materials and thicknesses. It solves the problem of uncontrollable adjustment force caused by the fixed stroke hydraulic cylinder in traditional tensioning mechanisms. Furthermore, by adjusting the preload of the vertical spring, the film tension can be further fine-tuned to ensure that the film tension remains appropriate during the laminating process, preventing film loosening or breakage. The adjusting laminating component, through a clever combination of a threaded rod, a first connector, and a second connector, enables rapid adjustment of the laminating machine height. The system is highly streamlined, eliminating the need to disassemble multiple fixing bolts or recalibrate transmission components, greatly simplifying the operation process. Furthermore, the height of the second mounting bracket can easily accommodate packaging materials of varying heights. The equilateral triangular roller layout ensures stable and uniform film transfer, making it suitable for various film materials, including ultrathin films and highly elastic films. In addition, the simple and durable component design reduces potential failure points and maintenance needs. The sliding insertion installation method of the vertical guide rod and sliding shaft reduces wear and jamming, extending the equipment's lifespan. The replacement and maintenance of the vertical spring are also relatively simple, reducing maintenance costs and time. Ultimately, by expanding the adjustment range and simplifying the operation process, production efficiency is significantly improved. In small-batch, multi-variety production modes, it can quickly adapt to different packaging material requirements, reducing changeover and adjustment times. Simultaneously, stable film tension and uniform lamination pressure ensure the quality of the finished packaging, reducing the defect rate and further enhancing production efficiency.

[0025] This utility model provides, for example Figures 1 to 4 An automatic film-coating packaging machine is shown, comprising: a housing 1, a control cabinet 2 on one side wall of the housing 1, a film feeder 3 on the top of the housing 1, and a set of casters installed at each of the four corners of the bottom of the housing 1. A first conveying device 5 is located at one end of the interior of the housing 1, and a second conveying device 4 is located at the other end of the first conveying device 5 at the same horizontal level. A tension adjustment assembly is located above the first conveying device 5 to adjust the film tension. A film-coating adjustment assembly is located above the second conveying device 4 to coat items of different sizes. This invention utilizes a tension adjustment assembly... The tension adjustment assembly and the tension adjustment coating assembly significantly improve the adjustment of film tension and adaptability to the coating needs of items of different sizes. They offer multiple benefits, including an expanded tension adjustment range, enhanced ease of operation, strong adaptability, reduced maintenance costs, and increased production efficiency. Specifically, the tension adjustment assembly employs a structure where a vertical guide rod 18 and a sliding shaft work in conjunction with a vertical spring 19. This allows the adjustment roller 8 to slide flexibly up and down within the vertical sliding groove 17 according to the film tension and requirements. This not only effectively expands the film tension adjustment range but also adapts to films of different materials and thicknesses, solving the problem of limited adjustment force caused by the fixed stroke hydraulic cylinder in traditional tensioning mechanisms. Uncontrollable problems are addressed by fine-tuning the film tension through adjusting the preload of the vertical spring 19, ensuring that the film tension remains appropriate throughout the laminating process and preventing film loosening or breakage. The adjusting laminating assembly utilizes a clever combination of the threaded rod 13, the first connector 12, and the second connector 14 to achieve rapid height adjustment of the laminating machine 20 without disassembling multiple fixing bolts or recalibrating transmission components, greatly simplifying the operation. Simultaneously, adjusting the height of the second mounting bracket 10 easily accommodates packaging materials of different heights. The equilateral triangular roller layout design ensures the stability and uniformity of film transfer, making it suitable for various film materials, including ultrathin films and... The equipment features a highly elastic film material; furthermore, its simple and durable component design reduces potential failure points and maintenance needs. The sliding insertion installation method of the vertical guide rod 18 and the sliding shaft reduces wear and jamming, extending the equipment's service life. The replacement and maintenance of the vertical spring 19 are also relatively simple, reducing maintenance costs and time. Ultimately, by expanding the adjustment range and simplifying the operation process, production efficiency is significantly improved. In small-batch, multi-variety production modes, it can quickly adapt to different packaging needs, reducing changeover and adjustment time. At the same time, stable film tension and uniform lamination pressure ensure the quality of finished packaging products, reducing the defect rate and further improving production efficiency.
[0026] Furthermore, in this example, such as Figure 3As shown, the tension adjustment assembly includes two sets of first mounting brackets 6, which are respectively mounted on the two end beams of the housing 1. Each first mounting bracket 6 has a set of vertical sliding grooves 17 on its corresponding upper sidewall. A set of vertical guide rods 18 are mounted on the upper and lower ends of the two sets of vertical sliding grooves 17, and sliding shafts are mounted on both sets of vertical guide rods 18. The sliding shafts are slidably inserted into the vertical guide rods 18 at their corresponding positions. Adjusting rollers 8 are mounted on the sliding shafts via two sets of double-row angular contact ball bearings. Vertical springs 19 are fitted onto each of the two sets of vertical guide rods 18. A first rotating roller 7 is mounted on one side of the two sets of first mounting brackets 6 below the adjusting roller 8 via a first rotating rod. A second rotating roller 9 is mounted on the other side of the two sets of first mounting brackets 6 below the adjusting roller 8 via a second rotating rod. The adjusting roller 8 and the second rotating roller 9 are arranged in an equilateral triangle. The width of the vertical sliding groove 17 is the same as the diameter of the sliding shaft, and the diameter of the sliding shaft is larger than the diameter of the vertical guide rod 18. The two ends of the sliding shaft are provided with first circular holes corresponding to the positions of the vertical guide rod 18. The diameter of the first circular holes is the same as the diameter of the vertical guide rod 18, and the vertical guide rod 18 is slidably inserted into the first circular holes at the corresponding positions. One end of the vertical spring 19 is fixedly installed on the bottom wall of the vertical sliding groove 17, and the other end of the vertical spring 19 is fixedly installed on the arc wall of the sliding shaft. The side walls of the two sets of first mounting brackets 6 are provided with second circular holes with the same diameter as the first rotating rod and the second rotating rod, corresponding to the positions of the first rotating rod and the second rotating rod. The tension adjustment assembly is fixed to the crossbeams at both ends of the housing 1 by the two sets of first mounting brackets 6 to form a stable support structure. Each set of first mounting brackets 6 has a set of vertical sliding grooves 17 on the upper side wall. Vertical guide rods 18 are mounted on the upper and lower ends of these two sets of vertical sliding grooves 17. A sliding shaft is slidably inserted onto the vertical guide rod 18. Adjusting rollers 8 are mounted on the sliding shaft via two sets of double-row angular contact ball bearings, ensuring the flexible sliding of the adjusting rollers 8 in the vertical direction. The first circular holes at both ends of the sliding shaft have the same diameter as the vertical guide rods 18, ensuring vertical sliding of the sliding shaft without wobbling. A vertical spring 19 is fitted between the sliding shaft and the bottom wall of the vertical sliding groove 17, with one end fixed to the bottom wall of the vertical sliding groove 17 and the other end fixed to the arc wall of the sliding shaft. When the membrane passes through the first rotating roller 7, the adjusting roller 8, and the second rotating roller 9, the membrane remains stable and uniform during transport due to their equilateral triangular arrangement. Changes in membrane tension act on the adjusting roller 8, causing it to slide up and down within the vertical sliding groove 17. The sliding shaft compresses or stretches the vertical spring 19, thereby automatically adjusting the membrane tension and preventing membrane slack or breakage. Meanwhile, by adjusting the preload of the vertical spring 19, the membrane tension can be further fine-tuned to ensure that the membrane tension remains appropriate throughout the coating process.
[0027] Furthermore, in this example, such as Figure 3As shown, the adjusting coating assembly includes two sets of fixed mounting plates 16, which are respectively mounted on the bottom fixing frame inside the housing 1. A set of second connecting posts 15 are respectively mounted on the outer wall of each of the two sets of fixed mounting plates 16. A second connector 14 is rotatably mounted on the second connecting post 15. A threaded rod 13 is threaded onto the other end of the second connector 14, and a first connector 12 is threaded onto the other end of the threaded rod 13. A first connecting post 11 is rotatably mounted onto the other end of the first connector 12. A second mounting frame 10 is mounted on the other end of both sets of first connecting posts 11. A coating machine 20 is mounted on the lower end face of the second mounting frame 10. The lower ends of the second mounting frame 10 are... A vertical guide rod is provided, and guide sleeves are installed on the inner wall of the housing 1 at positions corresponding to the vertical guide rod. A third hole matching the size of the second connecting post 15 is opened at one end of the second connector 14 corresponding to the second connecting post 15, and a first threaded groove matching the thread of the threaded rod 13 is opened on the second connector 14 at a position corresponding to the threaded rod 13. A fourth hole matching the size of the first connecting post 11 is opened at one end of the first connector 12 corresponding to the first connecting post 11, and a second threaded groove matching the thread of the threaded rod 13 is opened on the first connector 12 at a position corresponding to the threaded rod 13. The adjusting film-covering assembly is fixed to a fixing bracket at the bottom of the housing 1 via two sets of fixing mounting plates 16. A second connecting post 15 is installed on the outer wall of each set of fixing mounting plates 16, and a second connector 14 is rotatably mounted on the second connecting post 15. The other end of the second connector 14 is threaded with a threaded rod 13, and the other end of the threaded rod 13 is threaded with a first connector 12. The other end of the first connector 12 is rotatably fitted with a first connecting post 11. The other ends of the two sets of first connecting posts 11 are jointly fitted with a second mounting frame 10, and a laminating machine 20 is mounted on the lower end face of the second mounting frame 10. When it is necessary to adjust the height of the laminating machine 20 to accommodate different sizes of packaging materials, the second mounting frame 10 can be raised or lowered simply by rotating the threaded rod 13, utilizing its threaded engagement with the first connector 12 and the second connector 14. Vertical guide rods are provided at the lower ends of both ends of the second mounting frame 10, which engage with guide sleeves on the inner wall of the housing 1 to ensure the stability of the second mounting frame 10 during the raising and lowering process. This design eliminates the need to disassemble multiple fixing bolts or recalibrate transmission components, greatly simplifying the operation process and improving production efficiency. Meanwhile, the equilateral triangle roller layout design allows for a similar uniform coating effect to the equilateral triangle roller layout during the coating process by adjusting the height, ensuring the stability and uniformity of film transfer. It is suitable for films of various materials, including ultrathin films and highly elastic films.
