Description

Technical Field

[0001] This utility model relates to the field of ink dispersers, specifically a multifunctional ink disperser. Background Technology

[0002] An ink disperser is a mechanical device used to uniformly mix and refine ink raw materials such as pigments, resins, and solvents. Its core function is to break up agglomerated particles through mechanical shearing force, thereby improving the stability, coloring power, and flowability of inks. It is widely used in industries such as printing, coatings, and electronic inks.

[0003] Current ink dispersers use a fixed mechanical shear dispersion method to prepare ink. However, mechanical stirring relies on the shear force generated by a single rotating fan blade. The ink forms a fixed vortex in the barrel, resulting in insufficient dispersion of particles in the edge area and at the bottom of the barrel. This requires repeated adjustment of the fan blade position or manual intervention, which is inefficient. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a multifunctional ink disperser to solve the technical problems of traditional equipment, such as obvious dead angles at the edges and bottom due to fixed dispersion, separation of ultrasonic and mechanical shearing functions, low coupling efficiency of sound field and eddy current energy, and easy jamming and displacement of auxiliary mechanisms.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-functional ink disperser, comprising a disperser, the disperser including a mounting frame and a disperser barrel, wherein a functional mechanism is mounted on the top edge of the disperser barrel via a mounting mechanism;

[0006] The installation mechanism includes a circular slide rail with a groove on the outer side. The functional mechanism includes a movable frame with a first rubber wheel located below the top of the movable frame. The first rubber wheel engages with the groove and slides. A second motor is located at the top of the movable frame, and the output end of the second motor passes through the movable frame and is fixedly connected to the first rubber wheel.

[0007] The inner side of the movable frame extends into the dispersion barrel, and multiple piezoelectric ceramic vibrating plates are arranged at equal intervals from top to bottom.

[0008] The bottom inner side of the movable frame is provided with an installation groove, and a second rubber wheel is rotatably connected inside the installation groove, and the second rubber wheel abuts against the inner wall of the dispersion barrel.

[0009] By adopting the above technical solution, the piezoelectric ceramic vibrating plate dynamically covers all areas inside the barrel by sliding the movable frame along the circumference of the dispersion barrel, thus solving the problem of dead corners in traditional fixed dispersion. The first rubber wheel engages with the slide groove to ensure stable operation, and the second rubber wheel abuts against the inner wall of the barrel to prevent displacement, thus achieving efficient synergy between dispersion and ultrasonic functions.

[0010] Furthermore, after the second motor drives the first rubber wheel to rotate, it causes the movable frame to rotate around the circumference of the dispersing barrel.

[0011] By adopting the above technical solution, the second motor drives the first rubber wheel to move the movable frame in a circular motion, so that the ultrasonic coverage range expands dynamically with mechanical dispersion, eliminating the efficiency bottleneck of traditional equipment that requires stopping to adjust the position of the fan blades.

[0012] Furthermore, the entire material of the functional mechanism is stainless steel, and the functional mechanism is used to eliminate air bubbles and break up auxiliary materials.

[0013] By adopting the above technical solutions, the stainless steel functional structure maintains its structural strength under high-frequency vibration through corrosion resistance, while simultaneously eliminating bubbles and breaking up agglomerates of auxiliary materials, thus reducing the resource waste of traditional multi-process handling.

[0014] Furthermore, the bottom of the mounting frame is equipped with multiple casters, and a dispersion bucket is detachably connected to the middle of the top of the mounting frame.

[0015] By adopting the above technical solution, the combination of casters and detachable dispersion tanks enables flexible equipment movement and rapid material replacement and cleaning, adapting to the needs of small-batch, multi-variety production.

[0016] Furthermore, a linear motor is provided at the top rear end of the mounting bracket, and a machine head is provided at the moving end of the linear motor.

[0017] By adopting the above technical solution, the linear motor drives the machine head to raise and lower the dispersed fan blades, realizing rapid adjustment of the fan blade height and avoiding the inefficiency and safety hazards of traditional manual adjustment.

[0018] Furthermore, a first motor is provided at the bottom of the machine head, and a dispersion fan blade is installed at the bottom output end of the first motor via a connecting rod.

[0019] By adopting the above technical solution, the first motor directly drives the dispersion fan blades to rotate at high speed through a rigid connecting rod, ensuring the stability of power transmission and the uniformity of shear force; the connecting rod structure reduces the radial vibration of the fan blades, avoids ink splashing caused by eccentric motion, and at the same time meets the dispersion strength requirements of high viscosity inks.

[0020] Furthermore, the linear motor is used to raise and lower the dispersing fan blades, facilitating the removal of the dispersing barrel.

[0021] By adopting the above technical solution, the linear motor precisely adjusts the immersion depth of the dispersing fan blades through the vertical lifting head, adapting to the dispersion process of inks with different liquid levels; after the fan blades are lifted, they are completely separated from the dispersion tank, avoiding mechanical interference during the disassembly of traditional equipment, and significantly shortening the downtime for cleaning or replacing the tank.

[0022] Furthermore, the emitting surface of the piezoelectric ceramic vibrator is inclined toward the rotational center axis of the dispersing fan blades, and forms an acute angle with the moving direction of the movable frame.

[0023] By adopting the above technical solution, the piezoelectric ceramic vibrator is tilted toward the fan blade rotation axis, so that the ultrasonic cavitation effect and the mechanical shear eddy current direction are superimposed, thereby enhancing the particle crushing efficiency.

[0024] In summary, the present invention has the following main advantages:

[0025] This utility model incorporates an installation mechanism, a circular slide rail, a slide groove, a functional mechanism, a movable frame, a second motor, a first rubber wheel, a mounting groove, a second rubber wheel, and a piezoelectric ceramic vibrating plate. The movable frame slides along the circumference of the dispersion barrel, driving the piezoelectric ceramic vibrating plate to continuously emit ultrasonic waves to the inner edge and bottom dispersion dead corners of the barrel, breaking the limitations of traditional fixed eddy currents in fan blades. Moreover, the piezoelectric ceramic vibrating plate is tilted towards the fan blade rotation axis, and the ultrasonic cavitation effect and mechanical shear force form an energy superposition within the ink, improving particle crushing efficiency. Simultaneously, the second rubber wheel abuts against the inner wall of the barrel, using flexible contact to offset the vibration of the movable frame during operation, avoiding trajectory deviation or jamming caused by rigid friction. In addition, the stainless steel functional mechanism simultaneously achieves defoaming, auxiliary material crushing and dispersion, reducing the time consumed by traditional multi-equipment switching processes.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0032] A multi-functional ink disperser, such as Figure 1-4 As shown, it includes a disperser 1, which includes a mounting frame 101 and a disperser 107. A functional mechanism 3 is mounted on the top edge of the disperser 107 via a mounting mechanism 2.

[0033] The mounting mechanism 2 includes a circular slide rail 201, and a groove 202 is provided on the outer side of the circular slide rail 201. The functional mechanism 3 includes a movable frame 301, and a first rubber wheel 303 is provided below the top of the movable frame 301. The first rubber wheel 303 engages with the groove 202 and slides. A second motor 302 is provided on the top of the movable frame 301, and the output end of the second motor 302 passes through the movable frame 301 and is fixedly connected to the first rubber wheel 303.

[0034] The inner side of the movable frame 301 extends into the dispersion barrel 107, and multiple piezoelectric ceramic vibrating plates 306 are arranged at equal intervals from top to bottom.

[0035] The movable frame 301 has an inner mounting groove 304 at its bottom end, and a second rubber wheel 305 is rotatably connected inside the mounting groove 304. The second rubber wheel 305 abuts against the inner wall of the dispersion tank 107. This design guides the movable frame 301 to slide along the circumference of the top edge of the dispersion tank 107 through the circular slide rail 201 and slide groove 202 of the mounting mechanism 2, so that the piezoelectric ceramic vibrating plate 306 covers different depth areas inside the tank from top to bottom, breaking through the uneven edge dispersion caused by the fixed vortex of the traditional fan blade. The second rubber wheel 305 at the bottom end of the movable frame 301 flexibly abuts against the inner wall of the tank, offsetting the displacement caused by centrifugal force or ink resistance, and ensuring the stability of the ultrasonic emission direction of the piezoelectric ceramic vibrating plate 306. The non-metallic contact design between the first rubber wheel 303 and the slide groove 202 reduces friction loss and avoids jamming caused by ink splashing, realizing long-term synchronous operation of mechanical dispersion and ultrasonic treatment.

[0036] See Figure 1After the second motor 302 drives the first rubber wheel 303 to rotate, it causes the movable frame 301 to rotate around the circumference of the dispersion barrel 107. The second motor 302 drives the first rubber wheel 303 to roll in the slide groove 202, so that the movable frame 301 slides at a uniform speed around the circumference of the dispersion barrel 107. The ultrasonic emission area of ​​the piezoelectric ceramic vibrating plate 306 continuously covers different radial positions inside the barrel as the movable frame 301 moves, forming a dynamic complement with the fixed eddy current of the traditional fan blade 106, avoiding local insufficient dispersion caused by changes in ink viscosity. The circumferential motion path of the movable frame 301 is coaxial with the rotation axis of the dispersion fan blade 106, ensuring the spatiotemporal coupling consistency of the sound field and shear force.

[0037] See Figure 4 The entire material of the functional mechanism 3 is stainless steel. The functional mechanism 3 is used to eliminate bubbles and break up auxiliary materials. The use of stainless steel in the functional mechanism 3 resists the chemical corrosion of solvents and pigments in the ink and ensures the installation stability of the piezoelectric ceramic vibrating plate 306 under high-frequency vibration. The cavitation effect of the ultrasonic wave directly acts on the bubbles and auxiliary material agglomerates in the ink. The bubble shell is broken by local high pressure impact and the hard particles of auxiliary materials are broken up, realizing the integrated treatment of dispersion, defoaming and auxiliary material refinement, breaking through the efficiency limitation of traditional equipment that requires step-by-step operation.

[0038] See Figure 1 , Figure 4 The bottom of the mounting frame 101 is equipped with multiple casters 102, and the top center of the mounting frame 101 is detachably connected to a dispersion tank 107. The casters 102 at the bottom of the mounting frame 101 support omnidirectional movement of the equipment to adapt to workshop layout adjustments. The dispersion tank 107 is detachably connected to the top of the mounting frame 101, which facilitates the replacement of tanks of different capacities or materials to meet the dispersion needs of water-based and solvent-based inks, while simplifying the cleaning process of residual ink and reducing the risk of cross-contamination.

[0039] See Figure 4 A linear motor 103 is installed at the top rear end of the mounting frame 101. The moving end of the linear motor 103 is equipped with a machine head 104. The linear motor 103 achieves precise height adjustment of the dispersing fan blade 106 in the dispersing tank 107 by vertically lifting the machine head 104, adapting to the dispersion depth requirements of inks with different liquid levels. The linear drive method of the linear motor 103 avoids the mechanical backlash problem of traditional screw drive, ensuring lifting and positioning accuracy and operational stability. The modular design of the machine head 104 and the linear motor 103 facilitates quick inspection or replacement of core components, reducing maintenance costs.

[0040] See Figure 3 , Figure 4The bottom of the head 104 is equipped with a first motor 105. The bottom output end of the first motor 105 is connected to a dispersing fan blade 106 via a connecting rod. The first motor 105 directly drives the dispersing fan blade 106 through a rigid connecting rod, eliminating the energy loss of traditional belt or gear transmission and improving the mechanical energy transmission efficiency. The connecting rod structure enhances the radial support strength of the dispersing fan blade 106, suppresses eccentric vibration during high-speed rotation, and prevents ink splashing or barrel wall wear caused by fan blade oscillation. The rotation axis of the dispersing fan blade 106 is designed to coincide with the center of the dispersing barrel 107 to ensure symmetrical distribution of shear vortices and avoid the problem of uneven dispersion caused by traditional eccentric stirring.

[0041] See Figure 1 , Figure 4 The linear motor 103 is used to lift and lower the dispersing fan blade 106, facilitating the removal of the dispersing barrel 107. The linear motor 103 lifts the machine head 104 to completely detach the dispersing fan blade 106 from the dispersing barrel 107, eliminating the risk of mechanical interference between the fan blade and the barrel during disassembly of traditional equipment, simplifying cleaning or material changing operations. During the lifting process, the vertical movement path of the dispersing fan blade 106 is aligned with the axis of the dispersing barrel 107, avoiding scratching the barrel opening or sealing structure, extending the service life of the equipment. The quick detachment function of the dispersing fan blade 106 supports alternating operation of multiple barrels, adapting to the continuous production needs of small batches and multiple varieties of inks.

[0042] See Figure 1 The emitting surface of the piezoelectric ceramic vibrator 306 is tilted towards the rotational center axis of the dispersing fan blade 106 and forms an acute angle with the moving direction of the movable frame 301. The acute angle between the emitting surface of the piezoelectric ceramic vibrator 306 and the moving direction of the movable frame 301 causes the ultrasonic wave propagation path to intersect with the rotational vortex direction of the dispersing fan blade 106. The cavitation bubbles collapse rapidly under the dual action of shear force and sound pressure, generating a higher intensity local shock wave, which specifically breaks up large-diameter agglomerates. The tilted sound field design also extends the effective action distance of the ultrasonic wave in the ink and improves the utilization rate of sound energy.

[0043] The implementation principle of this embodiment is as follows: First, the first motor 105 is started to drive the dispersing fan blade 106 to rotate at high speed, and a dynamic vortex is formed in the dispersing barrel 107 through mechanical shearing force; the second motor 302 is started at the same time to drive the first rubber wheel 303 to roll at a constant speed along the groove 202 of the circular slide rail 201, and drive the movable frame 301 to slide continuously around the circumference of the dispersing barrel 107, so that the piezoelectric ceramic vibrating plate 306 moves with the movable frame 301 to cover different radial and depth areas inside the barrel;

[0044] During the sliding process of the movable frame 301, the second rubber wheel 305 flexibly contacts the inner wall of the dispersion barrel 107, and uses the deformation of the rubber to offset the barrel processing error and vibration offset, ensuring that the ultrasonic emission direction of the piezoelectric ceramic vibrating plate 306 is accurately pointed to the eddy center.

[0045] The ultrasonic waves emitted by the piezoelectric ceramic vibrator 306 induce cavitation in the ink. Its tilted design toward the rotation axis of the dispersing fan blade 106 causes the sound wave propagation path and the eddy current direction to intersect and superimpose, enhancing the efficiency of breaking up agglomerated particles. At the same time, the cavitation bubbles of the ultrasonic waves burst and generate local high-pressure impact, further eliminating bubbles inside the ink.

[0046] Functional mechanism 3 is made of stainless steel, which maintains structural strength under long-term high-frequency vibration through corrosion resistance, ensuring stable transmission of ultrasonic energy.

[0047] Ultimately, the synergistic effect of mechanical shearing and dynamic ultrasonic field breaks through the traditional dispersion dead zone, achieving uniform dispersion of ink throughout the entire area.
