Description
Technical Field
[0001] This utility model relates to the field of printing press technology, and in particular to a multi-functional cardboard printing press. Background Technology
[0002] In the modern printing industry, cardboard, as a common printing material, is widely used in packaging, labeling, stationery, and many other industries. Especially in mass production, the printing quality and transport efficiency of cardboard directly affect the overall printing capacity and product quality. To achieve efficient adaptation and stable transport of cardboard of different sizes, companies generally use specialized printing equipment for automated operations. Multifunctional cardboard printing machines have been developed in this context, possessing a certain degree of versatility and automation. They can complete a series of processes such as cardboard positioning, printing, and initial output, becoming one of the important pieces of equipment in the cardboard processing and production process.
[0003] In existing technologies, common paperboard printing machines typically employ manual or semi-automatic limiting structures for initial paperboard positioning, such as adjusting the paperboard width by moving baffles or sliders. Simultaneously, some devices are equipped with drive wheels or rollers to propel the paperboard within the printing channel. These devices have relatively simple structures, relying on manual adjustment of the limiting elements by the operator, combined with the conveying components to achieve the paperboard feeding and output process, basically meeting the standardized operational needs of general-sized paperboards.
[0004] However, existing paperboard printing presses generally employ sliding contact baffles, which are prone to displacement due to vibration or operational errors during use. This leads to decreased positioning accuracy and necessitates frequent manual readjustment, reducing work efficiency and operational convenience. Especially in continuous operation scenarios handling different paperboard sizes, the stability and adaptability of traditional baffle structures are insufficient to meet the demands of high-efficiency printing, limiting the equipment's practicality under complex conditions.

[0032] 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.
[0033] Reference Figures 1-3 This utility model provides an embodiment of a multi-functional cardboard printing machine, including a frame 1. The frame 1 provides a support base for the installation of the equipment, ensuring the stability and rigidity of the overall structure. A base 2 is fixedly connected to the top of the frame 1. The base 2 serves as a bearing platform for various functional components, providing necessary installation space and structural support. A limiting groove 4 is provided inside the base 2. The limiting groove 4 is used to constrain the sliding range of the subsequently installed components, playing a guiding and limiting role. A limiting block 5 is provided inside the base 2. The limiting block 5 is used to prevent excessive movement of the components, playing a protective and positioning role. A baffle 6 is fixedly connected to the top of the limiting block 5. The baffle 6 is used to limit the side of the cardboard to prevent the cardboard from shifting position during conveying or printing, ensuring printing accuracy. A positioning component is provided on the top of the baffle 6 to realize the adjustable and precise locking of the position of the baffle 6.
[0034] The positioning component includes an adjusting block 7, which can slide relative to the limiting groove 4, thereby driving the top of the adjusting block 7 to be fixedly connected to the bottom of the baffle 6, realizing the adjustable positioning of the baffle 6 in the horizontal direction to adapt to different sizes of paper sizes. The adjusting block 7 is slidably connected inside the limiting groove 4. Through this sliding fit structure, the baffle 6 can move smoothly and is not prone to shaking, improving positioning accuracy. The base 2 has a positioning groove 8 inside, which is used to limit the position of the locking structure of the adjusting component. A limiting plate is slidably connected inside the adjusting block 7. 10. The limiting plate 10, as a sliding component within the adjusting block 7, is used to cooperate with the limiting and resetting structure to achieve effective positioning and release. A positioning block 12 is fixedly connected to one side of the limiting plate 10. The positioning block 12 is used to embed into the positioning groove 8 after adjustment, thereby locking the position of the baffle 6 to prevent displacement during use and improve the reliability of the limiting. The positioning block 12 and the positioning groove 8 fit together to form a stable positioning fit. A telescopic rod 13 is provided inside the adjusting block 7. The telescopic rod 13 is the connecting core of the elastic resetting element and plays the role of restoring the positioning component to its original state. The telescopic rod 13 is fitted with a first spring 14 on its outer wall. The first spring 14 provides elastic support to the positioning block 12 through its elastic force, ensuring that the positioning block 12 is always in a pre-compression state for stable engagement. The adjusting block 7 is equipped with a limit component to constrain the sliding range of the limit plate 10 in the positioning mechanism, preventing it from exceeding the set stroke range. The top of the base 2 is fixedly connected to a printing machine 3, which is the main processing mechanism for paper jams and completes the printing output operation of graphics and text. The limit component includes a limit strip 9, which is used to limit the limit plate 10. The guide improves the accuracy and stability of the limit position. One side of the limit strip 9 is fixedly connected to the inside of the adjusting block 7 to form a fixed installation and cooperate with the limit action. The limit plate 10 has a second limit groove 11 inside. The second limit groove 11 is used to provide a sliding channel for the limit strip 9 to ensure smooth limit action. The limit strip 9 is slidably connected inside the second limit groove 11 to ensure the precise guidance of the positioning structure. The telescopic rod 13 and the first spring 14 are both fixedly connected between the limit plate 10 to ensure that the elastic force acts on the overall structure of the limit plate 10 and realize the effective reset function of the positioning mechanism.
[0035] Reference Figure 4 and Figure 5A support rod 15 is fixedly connected to the outer wall of the printing press 3. The support rod 15 provides a stable support mounting point for the subsequent transmission components, ensuring the strength and stability of the structure during operation. A connecting rod 16 is rotatably connected to the bottom of the support rod 15. The connecting rod 16 is used to realize the conversion of transmission motion. Through the rotatable connection with the support rod 15, a deformable movable support structure can be formed during paper feeding. A motor 18 is fixedly connected to one end of the connecting rod 16. The motor 18 serves as a power source, providing driving force to the rotating roller 17. The output end of the motor 18 is fixedly connected to the rotating roller 17. The rotating roller 17 is used to contact the paper and drive the output. Through its rotational motion, the paper is continuously fed, thereby cooperating with the printing operation and improving printing efficiency and automation. A connecting block 19 is rotatably connected to the bottom of the support rod 15 and one end of the connecting rod 16. Block 19 serves as a structural connection pivot, enhancing the linkage flexibility between connecting rod 16 and support rod 15, and facilitating the installation and coordination of subsequent elastic support components. A second telescopic rod 20 is installed between the connecting blocks 19, with both ends fixedly connected to the connecting blocks 19. This provides an extendable adjustment function between the connecting blocks 19, adapting to dynamic structural adjustments caused by changes in cardboard thickness or position. A second spring 21 is fitted onto the outer wall of the second telescopic rod 20, providing elastic support to ensure the structure automatically returns to its original position after being subjected to force, thus buffering and stabilizing the structural posture. Both ends of the second telescopic rod 20 and the second spring 21 are fixedly connected to one side of the connecting block 19, enabling the spring to effectively constrain the relative movement of the telescopic rod and improving the reliability and durability of the overall device during operation.
[0036] Working principle: When using this multi-functional cardboard printing machine, when adjusting the distance between the baffles 6, the bottom of the baffle 6 is limited in the limiting groove 4 by the limiting block 5. Then, the positioning block 12 in the adjusting block 7 is fitted into the positioning groove 8 for positioning. The positioning block 12 is limited in the adjusting block 7 by the limiting plate 10 and supported by the tension of the first spring 14, so that the positioning block 12 can be stably fitted into the positioning groove 8, thereby preventing the baffle 6 from sliding at will. This achieves the effect of adapting to limiting the baffle 6 for different sizes of cardboard and preventing it from sliding.
[0037] After the paper enters the printing press 3 for printing, the output end of the motor 18 drives the rotating roller 17 to rotate. The rotating roller 17 can drive the paper to be output. The rotating roller 17 is connected to the support rod 15 through the connecting rod 16 and is supported by the tension of the second spring 21, so that the rotating roller 17 can adapt to paper of different sizes and thicknesses. The second spring 21 is connected through the telescopic rod 20, which achieves the effect of assisting in the conveying of the paper.
[0038] 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.
