Description

Technical Field

[0001] This utility model relates to the field of printing roller body technology, and in particular to a height-adjustable printing roller structure. Background Technology

[0002] Liftable printing rollers are commonly used in the inking and printing processes of printing presses. By adjusting the height, the roller spacing can be precisely controlled. Their function is to adapt to substrates of different thicknesses, ensure uniform ink transfer and printing clarity, and raise the rollers during plate changes or cleaning to avoid scratches. They can also optimize printing pressure through height adjustment to improve print quality. They are suitable for various printing equipment such as flexographic and gravure printing.

[0003] In practical applications, existing height-adjustable printing roller structures, used in conjunction with cylinders and pressure regulating devices, can meet the basic requirements of printing, but the following problems still exist:

[0004] Common height-adjustable printing roller structures typically employ an interference fit during use. However, when disassembly and replacement are required, jamming can occur, making the process cumbersome and affecting work efficiency. Therefore, this application provides a height-adjustable printing roller structure to meet the requirements. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies and provide a height-adjustable printing roller structure.

[0025] 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.

[0026] like Figure 1 - Figure 4 As shown, this embodiment provides a technical solution: a height-adjustable printing roller structure, including a push rod 1 and a printing roller body 11 disposed on the side of the push rod 1, and further including:

[0027] The connecting component 2 includes a protective shell 21 connected to the top of the push rod 1. The inner wall of the protective shell 21 is connected to a limiting plate 22. A connecting plate 26 is provided on the side of the limiting plate 22. A snap-fit ​​block 28 is connected to the bottom of the connecting plate 26. A first sliding plate 210 and a second sliding plate 211 are provided on the side of the snap-fit ​​block 28.

[0028] Auxiliary component 3 includes a mounting base 31 connected to the side of the second sliding plate 211. A fixing plate 23 is also connected to the inner wall of the protective shell 21. A first spring piece 24 is connected to the bottom of the fixing plate 23. The bottom of the first spring piece 24 is connected to the top of the connecting plate 26. A slider 25 is connected to the side of the connecting plate 26. A groove 27 is provided on the side of the limiting plate 22. One end of the slider 25 extends into the inner cavity of the groove 27 and is slidably connected to the inner cavity of the groove 27. The side of the first sliding plate 210 is provided with... The connecting rod 29 has a second spring piece 213 inside its cavity. The side of the locking block 28 has an arc-shaped groove 212. The height of the printing roller body 11 can be adjusted by setting the push rod 1. The protective shell 21 provides support and protection for the fixing plate 23 and the limiting plate 22. The fixing plate 23 provides support for the first spring piece 24 and the connecting plate 26. The slider 25 and the sliding groove 27 cooperate to ensure that the locking block 28 moves smoothly. The movement trajectory is limited by a connecting rod 29, which provides support for the first sliding plate 210 and the second sliding plate 211. One end of the connecting rod 29 is fixedly connected to the side of the printing roller body 11. In use, the connecting rod 29 is manually pushed into the inner cavity of the protective shell 21. When the connecting rod 29 moves to a certain position, the side of the second sliding plate 211 contacts the side of the locking block 28, thereby causing the locking block 28 to move upward, and thus causing the locking block 28 to engage with the first sliding plate 210 and the second sliding plate 211. The sliding plate 211 engages, and when the engagement is complete, the arc-shaped groove 212 fits against the outer surface of the connecting rod 29, thus fixing the roller body 11 without affecting its rotational printing operation. During use, the second spring 213 is provided to improve the printing stability of the roller body 11. Similarly, when disassembly is required, the engaging block 28 can be manually pushed by a combination of manual labor and machinery to remove the roller body 11, making it easy to replace and effectively improving work efficiency.

[0029] Furthermore, such as Figures 2-4 As shown: The mounting base 31 has a snap-fit ​​groove 32 on its side and a protrusion 33 in the inner cavity of the push rod 1. By cooperating with the mounting base 31 and the snap-fit ​​groove 32, the rotational force of the drive motor can be transmitted to the printing roller body 11 during installation, thereby enabling the printing roller body 11 to perform rotational printing.

[0030] Working principle:

[0031] like Figure 1-4 As shown:

[0032] In use: First, push one end of the printing roller body 11 into the inner cavity of the protective shell 21. When the printing roller body 11 moves to a certain position, the side of the second sliding plate 211 contacts the side of the locking block 28, thereby causing the locking block 28 to drive the connecting plate 26 and the locking block 28 to move upward along the inner cavity of the groove 27, thus achieving the effect of compressing the first spring piece 24. At this time, the second sliding plate 211 continues to move, and the first spring piece 24 releases stress, thereby causing the locking block 28 to reset, thus realizing the arc groove 212. The inner wall of the connector 33 fits snugly against the outer surface of the connecting rod 29, enabling quick installation and snap-fit. Upon completion of installation, one end of the protruding rod 33 enters the inner cavity of the snap-fit ​​groove 32. At this time, the drive motor located on the side of the protruding rod 33 is activated, and the output shaft of the drive motor rotates forward, thereby driving the connecting rod 29 to rotate through the protruding rod 33. This enables the printing roller body 11 to perform rotational printing and dyeing operations. Similarly, when disassembly is required, manual and mechanical methods are used to move the snap-fit ​​block 28 upward, allowing the printing roller body 11 to be removed.

[0033] 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.
