Description

Technical Field

[0001] This utility model relates to the field of printing press technology, and in particular to a gravure printing machine for printing on packaging materials of various thicknesses. Background Technology

[0002] Adaptive gravure printing machines for printing on packaging materials of varying thicknesses can automatically adjust to changes in the thickness of different packaging materials, ensuring the stability and consistency of printing quality. Through an intelligent control system, ink distribution and pressure adjustment during the printing process are optimized, improving production efficiency, reducing material waste, and meeting diverse packaging needs. They are widely used in high-quality packaging printing in industries such as food and pharmaceuticals.

[0003] However, in actual use, the following shortcomings still exist. For example, existing gravure printing machines cannot achieve adaptive and stable printing on materials of different thicknesses, ensuring pressure matching and printing quality. When the material thickness changes, the pressure of the rubber roller and the printing plate roller cannot be matched. Thin materials are prone to wrinkles and damage due to excessive pressure, while thick materials suffer from missing prints and blurred images due to insufficient pressure. The fit between the squeegee and the printing plate roller is unstable, which can easily cause uneven ink scraping, resulting in excessively thick ink layers or white spots. The tension fluctuates greatly, the material is skewed, the registration accuracy decreases, and ghosting and misalignment occur. Frequent machine stops are required to manually adjust parameters, reducing production efficiency, increasing labor costs, and causing the scrap rate to soar. Especially in scenarios where multiple thicknesses of film and cardboard are mixed, it seriously affects the consistency and pass rate of mass production, restricts the packaging and printing industry's ability to respond to multi-variety, small-batch orders, and weakens the equipment's versatility and production efficiency. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose an adaptive gravure printing machine for printing on packaging materials of various thicknesses. To achieve the above objective, this utility model adopts the following technical solution: An adaptive gravure printing machine for printing on packaging materials of various thicknesses includes at least a base plate and an adaptive printing assembly. The adaptive printing assembly includes a support base connected to the base plate, a movable seat disposed within the support base, a servo motor mounted on the movable seat, a rubber roller connected to the output end of the servo motor, a guide rod connected within the support base, the movable seat slidably connected to the guide rod, a fixed seat connected to the bottom of the base plate near the guide rod, a telescopic spring disposed on the guide rod, a first rotating block rotatably connected to the fixed seat, a second rotating block rotatably connected to the other end of the first rotating block, the second rotating block rotatably connected to the movable seat, and a printing plate roller disposed on the side of the support base near the rubber roller. An auxiliary printing assembly includes a support plate connected to a support base near the printing plate roller, and a scraper is provided on the support plate.

[0005] Furthermore, one end of the telescopic spring is connected to the bottom of the movable seat, and the other end of the telescopic spring is connected to the fixed seat.

[0006] The beneficial effects of adopting the above-mentioned further solution are: the two ends of the telescopic spring are respectively connected to the bottom of the movable seat and the fixed seat. When the material thickness changes, the movable seat slides along the guide rod, and the telescopic spring expands and contracts due to the force. The elastic buffer adjusts the displacement of the movable seat, balances the pressure between the rubber roller and the printing plate roller, avoids sudden pressure changes, and enhances the adaptability stability to materials of different thicknesses.

[0007] Furthermore, a limiting groove is provided on the support base, and the movable base is slidably connected in the limiting groove.

[0008] The beneficial effects of adopting the above-mentioned further solution are: the limiting groove of the support seat provides a sliding track for the moving seat, the moving seat slides in the groove in a direction, limiting its offset, and with the double constraint of the guide rod, it ensures that the moving seat drives the rubber roller to move smoothly, ensuring accurate alignment with the printing plate roller and improving the stability of printing pressure adjustment.

[0009] Furthermore, a spring sheet is connected to the support plate, and the scraper is connected to the other end of the spring sheet.

[0010] The beneficial effects of adopting the above-mentioned further solution are: the spring sheet on the support plate connects to the scraper, and the spring sheet has elastic deformation capability, so that the scraper is always in close contact with the surface of the printing plate roller. When scraping off excess ink, it can adaptively adjust with the slight fluctuations of the printing plate roller to ensure uniform ink scraping and avoid incomplete ink scraping or damage to the printing plate roller caused by rigid contact.

[0011] Furthermore, a bracket is connected to the top side of the support base.

[0012] The beneficial effects of adopting the above-mentioned further solution are: the bracket on one side of the top of the support base plays a supporting and fixing role, provides an installation carrier for the unwinding shaft, stably erects the unwinding shaft above the printing assembly, ensures the stability of the material conveying path during the unwinding process, and provides a stable material supply foundation for subsequent printing processes.

[0013] Furthermore, a roll unwinding shaft is connected to the side of the bracket near the top.

[0014] The beneficial effects of adopting the above-mentioned further solution are: the unwinding shaft at the top of the support is used to install the roll of material to be printed. During operation, the unwinding shaft rotates to release the material, which, in conjunction with the subsequent printing components, enables continuous feeding. Its position setting ensures that the material enters the printing area at a suitable angle, reducing tension fluctuations during the conveying process.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, when the gravure printing machine is working, the adaptive printing component drives the rubber roller to rotate via a servo motor, which works in conjunction with the printing plate roller to complete the printing. When the material thickness changes, the moving seat slides along the guide rod, and the telescopic spring adaptively buffers and adjusts. At the same time, the first rotating block and the second rotating block are linked to assist the moving seat in stabilizing its displacement, ensuring that the pressure of the rubber roller and the printing plate roller is matched. In the auxiliary printing component, the scraper supported by the support plate is in close contact with the printing plate roller to scrape off excess ink. The guide rod ensures that the moving seat slides smoothly, and the fixed seat provides a fulcrum for the rotating block. This achieves adaptive and stable printing on materials of different thicknesses, ensuring pressure matching and printing quality. Attached Figure Description

Detailed Implementation

[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] like Figures 1 to 4As shown, this embodiment provides a technical solution: an adaptive gravure printing machine for printing on packaging materials of various thicknesses, including at least a base plate 1 and an adaptive printing component 2. The adaptive printing component 2 includes a support seat 21 connected to the base plate 1, a movable seat 22 disposed inside the support seat 21, a servo motor 23 mounted on the movable seat 22, a rubber roller 24 connected to the output end of the servo motor 23, a guide rod 25 connected inside the support seat 21, the movable seat 22 slidably connected to the guide rod 25, a fixed seat 26 connected to the bottom of the base plate 1 near the guide rod 25, a telescopic spring 27 disposed on the guide rod 25, a first rotating block 28 rotatably connected to the fixed seat 26, a second rotating block 29 rotatably connected to the other end of the first rotating block 28, the second rotating block 29 rotatably connected to the movable seat 22, and a printing plate roller 210 disposed on the side of the support seat 21 near the rubber roller 24. Furthermore, it also includes an auxiliary printing component 3, which includes a support plate 31 connected to the support base 21 near the printing plate roller 210. A scraper 33 is provided on the support plate 31. When the gravure printing machine is working, the adaptive printing component 2 drives the rubber roller 24 to rotate through the servo motor 23, which works with the printing plate roller 210 to complete the printing. When the material thickness changes, the moving seat 22 slides along the guide rod 25, and the telescopic spring 27 adaptively buffers and adjusts. At the same time, the first rotating block 28 and the second rotating block 29 are linked, and the auxiliary moving seat 22 is stably displaced to ensure that the pressure of the rubber roller 24 and the printing plate roller 210 is matched. In the auxiliary printing component 3, the scraper 33 supported by the support plate 31 is close to the printing plate roller 210 to scrape off excess ink. The guide rod 25 ensures that the moving seat 22 slides smoothly, and the fixed seat 26 provides a fulcrum for the rotating block. This realizes adaptive and stable printing for materials of different thicknesses, ensuring pressure matching and printing quality.

[0020] like Figures 1 to 4 As shown, one end of the telescopic spring 27 is connected to the bottom of the movable seat 22, and the other end of the telescopic spring 27 is connected to the fixed seat 26. The two ends of the telescopic spring 27 are respectively connected to the bottom of the movable seat 22 and the fixed seat 26. When the material thickness changes, the movable seat 22 slides along the guide rod 25. The telescopic spring 27 expands and contracts due to the force. The displacement of the movable seat 22 is adjusted by the elastic buffer, balancing the pressure between the rubber roller 24 and the printing plate roller 210, avoiding sudden pressure changes, and enhancing the adaptability stability to materials of different thicknesses. A limiting groove 211 is opened on the support seat 21. The movable seat 22 is slidably connected in the limiting groove 211. The limiting groove 211 of the support seat 21 provides a sliding track for the movable seat 22. The movable seat 22 slides in the groove in a direction, limiting its offset. With the double constraint of the guide rod 25, it is ensured that the movable seat 22 drives the rubber roller 24 to move smoothly, ensuring accurate alignment with the printing plate roller 210 and improving the stability of printing pressure adjustment. like Figure 1 , Figure 2 as well as Figure 5As shown, a spring sheet 32 ​​is connected to the support plate 31, and a scraper 33 is connected to the other end of the spring sheet 32. The spring sheet 32 ​​on the support plate 31 is connected to the scraper 33. The spring sheet 32 ​​has elastic deformation capability, so that the scraper 33 is always in close contact with the surface of the printing plate roller 210. When scraping off excess ink, it can adaptively adjust with the slight fluctuations of the printing plate roller 210 to ensure uniform ink scraping and avoid incomplete ink scraping or damage to the printing plate roller caused by rigid contact. A bracket 34 is connected to one side of the top of the support base 21. The bracket 34 on one side of the top of the support base 21 serves to support and fix it. The unwinding shaft 35 is provided as an installation carrier, and is stably mounted above the printing assembly to ensure a stable material conveying path during unwinding, providing a stable material supply foundation for subsequent printing processes. The unwinding shaft 35 is connected to the side of the bracket 34 near the top. The unwinding shaft 35 at the top of the bracket 34 is used to install the roll of material to be printed. During operation, the unwinding shaft 35 rotates to release the material, cooperating with the subsequent printing assembly to achieve continuous feeding. Its position setting ensures that the material enters the printing area at a suitable angle, reducing tension fluctuations during the conveying process.

[0021] For a comprehensive explanation of the operating principle of this utility model, please refer to... Figures 1 to 5 The following content is shown: When the gravure printing machine is working, the roll of material to be printed is mounted on the unwinding shaft 35 at the top of the support 34. The unwinding shaft 35 rotates to release the material and convey it to the printing area at a suitable angle. The support 34 provides stable support to ensure the stability of the material conveying path and reduce tension fluctuations.

[0022] During the printing stage, the adaptive printing component 2 plays a crucial role. The servo motor 23 drives the rubber roller 24 to rotate, working in conjunction with the printing plate roller 210 to complete the printing task. When the material thickness changes, the moving seat 22 slides along the limiting groove 211 and guide rod 25 of the support seat 21. The dual constraint mechanism of the limiting groove 211 and guide rod 25 effectively limits the offset of the moving seat 22, ensuring its smooth displacement.

[0023] Meanwhile, the telescopic spring 27 between the bottom of the movable seat 22 and the fixed seat 26 expands and contracts under force, and adjusts the displacement through elastic buffering to balance the pressure between the rubber roller 24 and the printing plate roller 210 and avoid sudden pressure changes; the first rotating block 28 on the fixed seat 26 is linked with the second rotating block 29 connected to the movable seat 22 to assist the movable seat 22 in achieving stable displacement and ensuring pressure matching.

[0024] The auxiliary printing component 3 works in sync. The spring 32 on the support plate 31 is connected to the scraper 33. The elastic deformation capability of the spring 32 ensures that the scraper 33 is always in close contact with the surface of the printing plate roller 210. When scraping off excess ink, it can adaptively adjust to the slight fluctuations of the printing plate roller 210 to ensure uniform ink scraping and avoid problems caused by rigid contact.

[0025] The gravure printing machine described in this invention achieves adaptive and stable printing on materials of different thicknesses through the close cooperation of its various components, thereby ensuring printing quality.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
