Description

Technical Field

[0001] This utility model relates to the field of printing technology, specifically to a gravure printing roller with adjustable installation dimensions. Background Technology

[0002] A printing roller for gravure printing is a special printing tool mainly used in gravure printing technology. The surface of this roller has recessed patterns or text of varying depths. These recessed areas can hold ink. During the printing process, as the roller rotates, the ink is filled into these recesses, and then the ink is transferred to the substrate, such as paper, plastic film, or other materials, by pressure, thereby reproducing the image or text corresponding to the surface of the roller.

[0003] However, in existing technologies, traditional printing rollers are typically installed using bolts. While this method ensures the stability of the roller during use, its drawbacks are obvious: it is only suitable for rollers of a specific size. This means that if a roller of a different diameter or length needs to be replaced, the entire installation system must be adjusted or even redesigned, which not only increases costs but also prolongs downtime and reduces production efficiency. Therefore, we provide a gravure printing roller with adjustable installation dimensions. Utility Model Content

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] This utility model provides a technical solution: such as Figures 1-5As shown, in this embodiment, a gravure printing roller with adjustable mounting size includes: a mounting mechanism 1, which includes a bracket 11. A printing roller 12 is disposed inside the bracket 11. Both ends of the printing roller 12 are provided with movable shells 13. Bearings 14 are disposed inside the two movable shells 13. Four sliders 15 are arranged in a circular array outside the two movable shells 13. Both ends of the printing roller 12 are fixedly connected to the inner walls of the two bearings 14. The outer side of the bearings 14 is fixedly connected to the inner wall of the movable shell 13. Four sliders 15 are fixedly connected in a circular array outside the movable shells 13. Fixed shells 16 are disposed outside the two movable shells 13. Four grooves 17 are arranged in a circular array on the inner wall of the two fixed shells 16. Two spring pieces 18 are disposed inside the two fixed shells 16. The outer side of the sliders 15 is slidably connected to the inner wall of the grooves 17. The side of the movable shell 13 near the fixed shell 16 is fixedly connected to one end of the spring piece 18. The other end of the spring piece 18 is fixedly connected to the inner wall of the fixed shell 16 away from the movable shell 16. One side of the moving shell 13 is fixedly connected. Two positioning posts 19 are provided on the side of the two fixed shells 16 away from the printing roller 12. The two positioning posts 19 are fixedly connected on the side of the fixed shell 16 away from the printing roller 12. The outside of the positioning posts 19 is connected to the slots opened in the inner wall of the bracket 11. Screws 110 are provided in the threaded grooves opened in the four positioning posts 19. Two support platforms 111 are provided on both sides of the inner wall of the bracket 11. One end of the screw 110 passes through the slot opened in the bracket 11 and is threadedly connected to the inner wall of the threaded groove opened in the positioning post 19. Two support platforms 111 are fixedly connected on both sides of the inner wall of the bracket 11. Adjusting bolts 112 are provided in the threaded grooves opened in the four support platforms 111. Clamping plates 113 are provided on the outside of the four adjusting bolts 112 near the fixed shell 16. Adjusting bolts 112 are threadedly connected in the threaded grooves opened in the support platforms 111. The side of the adjusting bolts 112 near the fixed shell 16 is rotatably connected to the outside of the clamping plates 113. A collecting mechanism 2 is provided at the bottom of the bracket 11.

[0024] In this embodiment, when different sizes of printing rollers 12 need to be installed, the different sizes of fixing shells 16 of the printing rollers 12 can be placed between two clamping plates 113. By rotating the adjusting bolts 112 respectively, the height of the connected clamping plates 113 can be adjusted. Therefore, the upper and lower clamping plates 113 can clamp and position the fixing shells 16 of different sizes to ensure the stability during subsequent installation. The positioning pins 19 inserted into the slots opened in the bracket 11 can ensure the accuracy of the installation of the printing rollers 12. Then, screws 110 are used to pass through the bracket 11 and the threaded positioning pins. The threaded groove 19 is used to fix the printing roller 12 on the bracket 11. In addition, when the positioning post 19 is inserted into the slot of the bracket 11, the movable shell 13 at one end of the printing roller 12 needs to be squeezed to ensure that the positioning post 19 at the other end is positioned and inserted into the slot of the bracket 11. Therefore, when the movable shell 13 is squeezed, it will be recessed into the fixed shell 16, and the slider 15 will slide in the groove 17 to ensure the stability of the movable shell 13 when it is recessed and prevent rotation. The spring 18 will be squeezed and contracted by the recess of the movable shell 13.

[0025] like Figures 1-5 As shown, the collection mechanism 2 includes a base 21, a slot at the top of the base 21 with a mesh 22 fixedly connected to the inner wall, and a collection drawer 23 is provided inside the base 21.

[0026] In this embodiment, when the printing roller 12 is in use, some ink dye may drip naturally and affect the working environment. Therefore, the collection drawer 23 can collect these unused ink dyes. The mesh 22 can block items that may fall in the working environment and prevent them from coming into contact with the ink dyes in the collection drawer 23.

[0027] This utility model provides a gravure printing roller with adjustable installation size, and its specific working principle is as follows:

[0028] When faced with installation requirements for printing rollers 12 of different sizes, the height of the two clamping plates 113 can be precisely controlled by rotating the adjusting bolts 112 respectively. This allows the upper and lower clamping plates 113 to tightly hold the fixed shells 16 of different sizes, thereby ensuring the stability of the printing rollers 12 during installation. When it is necessary to install the printing rollers 12 on the bracket 11, the positioning pins 19 are inserted into the slots opened in the bracket 11 to ensure that the printing rollers 12 will not shift or misalign during installation. Then, screws 110 are used to pass through the threads opened between the bracket 11 and the threaded positioning pins 19. The groove is fixed so that the printing roller 12 can be firmly installed on the bracket 11. It should be noted that when inserting the positioning post 19 into the slot opened in the bracket 11, the movable shell 13 at one end of the printing roller 12 needs to be squeezed. The purpose of this is to make the movable shell 13 recess into the fixed shell 16, thereby providing more space for the positioning post 19 at the other end to be inserted into the slot opened in the bracket 11. Only when the movable shell 13 is sufficiently squeezed can the positioning post 19 at the other end be accurately inserted into the slot, thus completing the entire installation process.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
