Description

Technical Field

[0001] This utility model relates to the field of ink particle size testing technology, and in particular to an ink particle size laser tester. Background Technology

[0002] An ink particle size laser meter is an instrument based on the principle of laser diffraction, specifically designed to measure the particle size distribution of ink particles. It assesses the size and distribution characteristics of particles in ink by analyzing laser scattering signals, thereby helping manufacturers optimize product quality. This instrument uses laser diffraction technology and can measure the particle size distribution range in ink, typically from 20 nanometers to 2 millimeters. An ink particle size laser meter not only consists of testing equipment but also includes ink particle dispersion equipment.

[0003] In current methods, instrument calibration is required before sample preparation. The sample is then placed in the laser particle size analyzer to begin testing the ink particle size. Sample preparation involves diluting the ink with a suitable solvent to a transparent or semi-transparent state. This is often done by directly adding the ink to the solvent and then ultrasonically dispersing it using an ultrasonic motor. However, due to the diverse composition of inks, some inks that are difficult to disperse require more time during ultrasonic dispersion, significantly delaying the testing process and affecting the efficiency of ink particle size measurement. Therefore, we propose a laser particle size analyzer for ink. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Example Reference Figures 1-4 A laser particle size analyzer for ink includes a laser analyzer 1, a control box 2 is provided on the top of one end of the laser analyzer 1, a controller is provided inside the control box 2, the controller is connected to the laser analyzer 1 through wires, and is used to test the particle size of the dispersed ink solvent. A touch screen is provided on the top of the control box 2, and the touch screen is connected to the controller through wires so that the laser analyzer 1 can be controlled.

[0019] A mixing tank 4 is provided on one side of the laser tester 1. An ultrasonic motor 18 is installed at the bottom of the mixing tank 4. The ultrasonic motor 18 is connected to the controller through a wire. The mixing tank 4 is fixed on the support base 3. A support frame 11 is provided above the mixing tank 4. The support frame 11 is installed on a lifting device so that the support frame 11 can be raised and lowered freely above the mixing tank 4.

[0020] Among them, such as Figure 1 and Figure 3As shown, the lifting device includes a U-shaped frame 5, the opening of which is located away from the mixing tank 4, and the bottom of the U-shaped frame 5 is connected to the support base 3 via a connecting frame 6. A strip groove 7 is provided on the side of the U-shaped frame 5 near the mixing tank 4. A lead screw 8 is provided inside the U-shaped frame 5, and the end of the lead screw 8 is rotatably connected to the end inside the U-shaped frame 5. A first drive motor 9 is installed on the top of the lead screw 8. The first drive motor 9 is fixed on the U-shaped frame 5 and is connected to the controller via a wire. A movable seat 10 is threaded onto the lead screw 8. The support frame 11 passes through the strip groove 7 and is fixed to the movable seat 10, providing power for the lifting and lowering of the support frame 11 above the mixing tank 4.

[0021] Furthermore, in order to improve the support strength of the connecting frame 6 to the U-shaped frame 5, several reinforcing plates arranged at intervals are installed at the bottom of the U-shaped frame 5. One side of the reinforcing plate is fixed to the U-shaped frame 5, and the other side of the reinforcing plate is fixed to the connecting frame 6.

[0022] Meanwhile, in order to prevent the support frame 11 from deflecting when the lead screw 8 rotates, thereby affecting the relative state between the support frame 11 and the mixing tank 4, slide rails 25 are installed on both sides of the strip groove 7, and sliders 24 are slidably installed on the slide rails 25. The sliders 24 are fixed to the support frame 11 to limit the movement of the support frame 11 and ensure that the support frame 11 always moves along the axial direction of the lead screw 8.

[0023] like Figure 2 and Figure 4 As shown, a rotating tube 12 is installed through the end of the support frame 11 away from the lifting equipment. The top of the rotating tube 12 is rotatably connected to the support frame 11. A drive mechanism is also installed on the top of the rotating tube 12 to drive the rotating tube 12 to rotate. An L-shaped tube 13 is rotatably connected to the top of the rotating tube 12. The other end of the L-shaped tube 13 is a feed pipe 14. The bottom of the feed pipe 14 is installed on the inlet of the conveying pump 15. The conveying pump 15 is connected to the support frame 11 through a bracket. A discharge pipe 16 is installed at the outlet of the conveying pump 15. The conveying pump 15 is connected to the controller through a wire. It can draw ink solvent located at the bottom of the mixing tank 4 and discharge it from the discharge pipe 16. This allows the ink solvent in the mixing tank 4 to circulate up and down, realizing the turning of the ink solvent. Multiple spaced blades 17 are installed on the bottom outer wall of the rotating tube 12. With the operation of the ultrasonic motor 18 and the rotation of the blades 17, the ink and solvent are quickly mixed, allowing the ink to be diluted more quickly.

[0024] In addition, in actual use, the mixing tank 4 is either a transparent glass tank or a transparent plastic tank, so that the operator can observe the ink dilution inside the mixing tank 4 from the outside. At the same time, the setting of the feed pipe 14 also makes it convenient to temporarily add ink or solvent into the mixing tank 4. In actual use, a sealing rubber plate 22 with a cross-shaped opening is installed inside the top of the feed pipe 14 to reduce the amount of dust and other debris falling into the mixing tank 4 from the feed pipe 14.

[0025] Furthermore, the drive mechanism includes a first gear 19, which is coaxially mounted on the top of the rotating tube 12, and a second gear 20 meshes with the side of the first gear 19. A rotating shaft is coaxially mounted on the second gear 20, and the bottom of the rotating shaft is rotatably connected to the support frame 11. A second drive motor 21 is mounted on the top of the rotating shaft. The second drive motor 21 is fixed to the support frame 11 by a bracket, and the second drive motor 21 is connected to the controller by a wire to provide power for the rotation of the blade 17.

[0026] When in use, as the lifting device lowers the blade 17 into the mixing tank 4, a top cover 23 corresponding to the mixing tank 4 is provided below the support frame 11. The top cover 23 is rotatably connected to the rotating tube 12, and the discharge tube 16 is fixedly installed through the top cover 23. The top cover 23 will cover the top of the mixing tank 4, thereby sealing the top of the mixing tank 4 and preventing ink solvent from spilling out from the top of the mixing tank 4.

[0027] Specifically, in use, ink and solvent are first added to mixing tank 4. Then, the first drive motor 9 is started to lower blade 17 into mixing tank 4. Subsequently, the second drive motor 21 operates, driving the rotating tube 12 to rotate and begin diluting the ink. With the operation of the ultrasonic motor 18 and the extraction of solution from the bottom of mixing tank 4 by the delivery pump 15, the ink is agitated and turned in the solvent in multiple directions. At this time, the operator can observe the ink dilution through mixing tank 4. If ink or solvent needs to be added, a dropper can be used to draw ink or solvent and add it into mixing tank 4 through feed pipe 14. After dilution is completed, the first drive motor 9 will lift blade 17, and the operator can directly start the delivery pump 15 and place the test tube at discharge pipe 16 to collect the diluted ink solution. Finally, the test tube containing the ink solution is placed in laser tester 1 to begin testing the ink particle size.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
