Description

Technical Field

[0001] This utility model relates to the field of water-based ink production technology for printing, and more specifically, it relates to a high-speed disperser for water-based inks for printing. Background Technology

[0002] In the production process of water-based inks for printing, the requirements for dispersion processes vary significantly depending on the ink formulation. High-solids metal inks require stronger shearing forces to break up pigment agglomerates, while low-viscosity dye-based inks require attention to the uniform mixing of the fluid. Existing dispersion equipment mostly uses fixed-angle stirring blades, making it difficult to dynamically adjust the flow field morphology according to the material characteristics. This results in high-viscosity inks being prone to dispersion dead zones, while low-viscosity inks generate ineffective energy consumption due to excessive shearing. This rigid structure severely restricts the equipment's adaptability to the process of multi-formulation systems, forcing manufacturers to configure dedicated equipment for different ink categories, significantly increasing fixed asset investment costs.

[0029] The locking mechanism includes an abutment rod 16, a sliding sleeve 17, an abutment plate 18, and a rotating sleeve 19. The abutment rod 16 is fixed to the outer wall of multiple positioning blocks 14 and is slidably connected to the limiting sleeve 10. The sliding sleeve 17 slides on the outer wall of the connecting rod 15. The abutment plate 18 is fixed to the bottom surface of the sliding sleeve 17. The rotating sleeve 19 is threadedly connected to the outer wall of the connecting rod 15. The principle is to rotate the rotating sleeve 19 to drive the sliding sleeve 17 to move axially, so that the abutment plate 18 presses against the abutment rod 16 to achieve angle locking.

[0030] A mounting bracket 20 is fixedly provided on the outer wall of the stirring rod 5. A side scraper 21 is fixedly provided on the outer side of the mounting bracket 20, and a bottom scraper 22 is fixedly provided at the bottom end of the mounting bracket 20. The principle is to use the rotating mounting bracket 20 to drive the side scraper 21 and the bottom scraper 22 to scrape off the residual material on the inner wall and bottom of the tank 1.

[0031] The top of the tank body 1 is rotatably connected to an opening and closing cover 23, which is used to quickly open and close the tank body 1 by rotating the opening and closing cover 23.

[0032] A guide bar 24 is fixedly provided on the outer wall of the connecting rod 15, and a guide groove 25 is provided on the inner wall of the sliding sleeve 17. Multiple sets of guide bars 24 and guide grooves 25 are provided and slidably connected.

[0036] In this embodiment, during use, the rotating connecting rod 15 drives the stirring blade 6 to rotate. At the same time, the connecting rod 15 drives the limiting sleeve 10 to rotate within the positioning sleeve 8 via the rotating rod 9. The rounded corners on the outer side of the multiple positioning grooves 11 push the multiple positioning blocks 14 to disengage from the positioning grooves 11 and slide within the movable groove 12. Simultaneously, the multiple positioning blocks 14 press the multiple push springs 13. When the multiple positioning blocks 14 move to the outer side of the next positioning groove 11, the push spring 13 resets and pushes the positioning blocks 14 to engage within the positioning groove 11, so that the rotation of the connecting rod 15 forms a gear, allowing for graded adjustment of the stirring blade 6. When the appropriate angle is reached, the rotating sleeve 19 engages with the outer wall of the connecting rod 15 through a threaded connection, causing the rotating sleeve 19 to move along the connecting rod 15 and push the sliding sleeve 17 to slide along the multiple guide bars 24 via the thrust bearing 26. The sliding sleeve 17 pushes the abutment plate 18 to abut against the top of the multiple abutment rods 16 to lock the rotating rod 9, thus completing the angle adjustment and fixation of the stirring blade 6.

[0037] More specifically, the motor 3 is started so that its output end drives the stirring rod 5 to rotate. The stirring rod 5 rotates along the support frame 4 and drives multiple sets of stirring blades 6 to stir the material in the tank 1. The side scraper 21 and the bottom scraper 22 scrape off the raw material attached to the inner wall of the tank 1.

[0038] In summary, during use or operation of the overall equipment: During use, the rotating connecting rod 15 drives the stirring blade 6 to rotate. Simultaneously, the connecting rod 15, through the rotating rod 9, drives the limiting sleeve 10 to rotate within the positioning sleeve 8. The rounded corners on the outer sides of multiple positioning grooves 11 push multiple positioning blocks 14 out of the positioning grooves 11 and slide within the movable groove 12. Simultaneously, the multiple positioning blocks 14 press against multiple push springs 13. When the multiple positioning blocks 14 move to the outer side of the next positioning groove 11, the push spring 13 resets, pushing the positioning block 14 into the positioning groove 11, thus creating a gear position for the rotation of the connecting rod 15, allowing for graded adjustment of the stirring blade 6. When the appropriate angle is reached, the rotating sleeve 19 engages with the outer wall of the connecting rod 15 through a threaded connection, causing the rotating sleeve 19 to move along the connecting rod 15 and push the sliding sleeve 17 along multiple guide bars 24 via the thrust bearing 26. The sliding sleeve 17 pushes the abutment plate 18 to abut against the top of multiple abutment rods 16, locking the rotating rod 9 and completing the angle adjustment and fixation of the stirring blade 6.

[0039] The motor 3 is started so that its output end drives the stirring rod 5 to rotate. The stirring rod 5 rotates along the support frame 4 and drives multiple sets of stirring blades 6 to stir the material in the tank 1. The side scraper 21 and the bottom scraper 22 scrape off the raw material attached to the inner wall of the tank 1.
