Description
Technical Field
[0001] This utility model relates to a dispersion mixing tank, and more particularly to a dispersion mixing tank for the production of glass printing coatings, belonging to the field of glass printing technology. Background Technology
[0002] In the prior art, such as the utility model with application number 202321239700.7, a dispersion mixing tank for water-based coatings is disclosed. The tank body of this dispersion mixing tank for water-based coatings is provided with a main stirring rod and an auxiliary stirring rod rotating in opposite directions, so that the main dispersion disc and the auxiliary dispersion disc disperse the emulsion inside the tank in different directions, resulting in a better dispersion effect.
[0003] The above-mentioned applications still have shortcomings:
[0004] When this type of water-based coating is mixed in a dispersion tank, it relies on the horizontal rotation of the dispersion disc. The material mixes slowly from top to bottom, which easily leads to insufficient mixing, dead and dead corners, poor pigment dispersion, insufficient convection between upper and lower layers, and low mixing efficiency. Insufficient dispersion and mixing will lead to uneven distribution of components, affecting the color uniformity during printing and causing color spot defects during printing.
[0005] To address these issues, a dispersion mixing tank for glass printing coating production was designed. Summary of the Invention
[0006] The main objective of this invention is to provide a dispersion mixing tank for glass printing coating production, in order to solve the problems mentioned in the background art.
[0007] The objective of this utility model can be achieved by adopting the following technical solution:
[0008] A dispersion mixing tank for glass printing coating production includes a tank body, a cover mounted on the top of the tank body, a motor mounted on the top of the cover, a reciprocating screw fixed to the output shaft of the motor, a rotating shaft fixed to the bottom of the reciprocating screw, a dispersion disc mounted at the bottom end of the rotating shaft, a bracket uniformly installed in a ring shape inside the cover, an inner cylinder fixed between the ends of the bracket, a slip ring sleeved on the outer side of the reciprocating screw, a crescent pin rotating inside the slip ring and slidably connected to the reciprocating screw, L-shaped rods symmetrically arranged at the bottom of the slip ring, each L-shaped rod having a toggle shaft fixed to its bottom end, through holes symmetrically opened at the bottom of the inner cylinder matching the L-shaped rods, and a stirring mechanism arranged between the cover and the reciprocating screw.
[0009] Preferably, a feeding hopper is installed on the cover, one end of which penetrates and extends into the interior of the cover, and an extension pipe is fixed to one end of the feeding hopper.
[0010] Preferably, the stirring mechanism includes an external gear ring and a fixed shaft. The external gear ring is sleeved and installed on the outer side of the top of the reciprocating screw. The fixed shaft is symmetrically installed on the inner top wall of the cover and is rotatably connected to the inner top wall of the cover. Gears are sleeved on the outer side of the fixed shaft and all gears mesh with the external gear ring. Dispersing blades are evenly arranged at the bottom of the fixed shaft.
[0011] Preferably, the outer side of the slip ring is evenly provided with balls, and the balls are slidably connected to the inside of the inner cylinder.
[0012] Preferably, stirring blades are provided at equal angles on the outer side of the actuating shaft, with the stirring blades tilted at an angle of 30°-45°.
[0013] Preferably, an elastic sealing ring is embedded at the connection between the lid and the tank, and the sealing ring is made of fluororubber.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this embodiment proposes a dispersion mixing tank for glass printing coating production, including a tank body 1, a cover 2 installed on the top of the tank body 1, a motor 3 installed on the top of the cover 2, a reciprocating screw 4 fixed to the output shaft of the motor 3, a rotating shaft 5 fixed to the bottom of the reciprocating screw 4, a dispersion disc 6 installed at the bottom end of the rotating shaft 5, a bracket 14 uniformly installed in a ring shape inside the cover 2, an inner cylinder 12 fixed between the ends of the bracket 14, the bottom end of the reciprocating screw 4 passing through the middle position of the bottom of the inner cylinder 12 and rotatably connected to the inner cylinder 12, a slip ring 8 sleeved on the outside of the reciprocating screw 4, a crescent pin 9 rotating inside the slip ring 8, and the crescent pin 9 slidably connected to the reciprocating screw 4, the crescent pin 9 sliding along the spiral groove of the reciprocating screw 4, driving the slip ring 8 to move axially;
[0033] The bottom of the slip ring 8 is symmetrically provided with L-shaped rods 10, and the bottom end of each L-shaped rod 10 is fixed with a toggle shaft 11. The bottom of the inner cylinder 12 is symmetrically provided with through holes 13 that match the L-shaped rods 10. The through holes 13 allow the L-shaped rods 10 to slide up and down within the through holes 13. A stirring mechanism 7 is provided between the cover 2 and the reciprocating screw.
[0034] After the drive motor 3 is started, its output shaft transmits torque to the reciprocating screw 4 and the rotating shaft 5 through the coupling. The rotating shaft 5 drives the dispersing disk 6 to rotate at high speed. Using centrifugal force and fluid shear effect, the glass printing coating is radially dispersed. At the same time, under the guidance and limiting effect of the through hole 13 on the L-shaped rod 10, the reciprocating screw 4 drives the slip ring 8 through the crescent pin 9 to convert the rotational motion into reciprocating linear motion along the axis of the through hole 13. The slip ring 8, together with the L-shaped rod 10 and the actuating shaft 11, periodically moves up and down in the tank 1. The radial shear of the dispersing disk 6 forms a horizontal vortex, and the axial stirring of the actuating shaft 11 generates vertical convection. The two superimpose to form turbulence. Example 2
[0035] The solution in Example 1 will be further described below with reference to its specific working method.
[0036] like Figure 4 and Figure 5 As shown, in a preferred embodiment, based on the above method, a feeding hopper 15 is further installed on the cover 2, one end of the feeding hopper 15 penetrates and extends into the interior of the cover 2, and an extension pipe 16 is fixed to one end of the feeding hopper 15.
[0037] Raw materials are poured in through the feed hopper 15 and flow into the extension pipe 16. The raw materials are then transported into the tank 1 along the extension pipe 16. This optimizes the flow path of the raw materials and prevents splashing and contamination of internal components, thus serving as a guide and protection mechanism.
[0038] like Figure 1 Figure 4 As shown, in a preferred embodiment, based on the above method, the stirring mechanism 7 further includes an external gear ring 701 and a fixed shaft 702. The external gear ring 701 is sleeved and installed on the outer side of the top end of the reciprocating screw 4. The external gear ring 701 is circumferentially fixed to the top end of the reciprocating screw 4 by a flat key and rotates synchronously with the reciprocating screw. The fixed shaft 702 is symmetrically installed on the inner top wall of the cover 2 and is rotatably connected to the inner top wall of the cover 2. Gears 703 are sleeved on the outer side of the fixed shaft 702 and all gears 703 mesh with the external gear ring 701. Dispersing blades 704 are evenly arranged at the bottom of the fixed shaft 702.
[0039] When the reciprocating screw 4 rotates, it drives the external gear ring 701 to rotate. The external gear ring 701 drives the gear 703 that meshes with it to rotate. The gear 703 drives the fixed shaft 702 and the dispersing blade 704 to rotate, thereby stirring the coating and accelerating the dispersion and stirring of the material.
[0040] like Figure 2 As shown, in a preferred embodiment, based on the above method, the outer side of the slip ring 8 is further provided with balls, and the balls are slidably connected to the inside of the inner cylinder 12.
[0041] By converting sliding friction into rolling friction through ball bearings, frictional resistance is reduced, making the slip ring 8 slide up and down more smoothly and reducing energy consumption. At the same time, the even distribution of ball bearings can balance the radial force, prevent the slip ring 8 from shaking or shifting, ensure the motion accuracy of the L-shaped rod 10 and the actuating shaft 11, and improve the stability of the three-dimensional stirring flow field.
[0042] like Figure 1 As shown, in a preferred embodiment, based on the above method, a stirring blade is further provided at an equal angle on the outer side of the actuating shaft 11, and the tilt angle of the stirring blade is 30°-45°.
[0043] The upward movement of the tilting blades generates an upward thrust, while the downward movement generates a downward pull, which enhances the mixing efficiency of the coating and improves the shearing and dispersion effect on pigment particles in glass printing coatings.
[0044] like Figure 1 As shown, in a preferred embodiment, based on the above method, an elastic sealing ring is further provided at the connection between the cover 2 and the tank 1, and the sealing ring is made of fluororubber.
[0045] Fluororubber has excellent chemical corrosion resistance and can resist the erosion of solvents such as alcohols and ethers in glass printing coatings. At the same time, its elastic structure can compensate for vibration deformation during equipment operation and ensure sealing performance.
[0046] like Figure 1 As shown, in a preferred embodiment, based on the above method, the L-shaped rod 10 and the actuating shaft 11 are further connected by threads and locked with an anti-loosening nut.
[0047] The structure is simple and easy to disassemble, making it convenient to remove the actuating shaft 11 by unscrewing the nut when the stirring blade is worn and needs maintenance. Example 3
[0048] The solutions in Embodiments 1 and 2 will be further described below with reference to their specific working methods.
[0049] Raw materials are poured in through the feed hopper 15 and flow into the extension pipe 16. They are then transported along the extension pipe 16 into the tank 1, optimizing the material flow path and preventing splashing that could contaminate internal components. This process serves both guiding and protective functions. After starting the drive motor 3, its output shaft transmits torque to the reciprocating screw 4 and rotating shaft 5 via a coupling. The rotating shaft 5 drives the dispersion disc 6 to rotate at high speed, utilizing centrifugal force and fluid shear effect to radially disperse the glass printing coating. Simultaneously, under the guidance and limiting effect of the through hole 13 on the L-shaped rod 10, the reciprocating... The lead screw 4 drives the slip ring 8 through the crescent pin 9 to convert the rotational motion into reciprocating linear motion along the axis of the through hole 13. The slip ring 8 drives the L-shaped rod 10 and the actuating shaft 11 to move up and down periodically inside the tank 1. When the reciprocating lead screw 4 rotates, it drives the external gear ring 701 to rotate. The external gear ring 701 drives the gear 703 that meshes with it to rotate. The gear 703 drives the fixed shaft 702 and the dispersing blade 704 to rotate, thereby stirring the coating and accelerating the dispersion and stirring of the material. Combined with the dispersion of the dispersion disc 6 and the up and down tumbling disturbance of the actuating shaft 11, a three-dimensional turbulent flow field is formed, which improves the working efficiency.
[0050] The above description is only a further 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 scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
