Description

Technical Field

[0001] This utility model relates to the field of pigment manufacturing technology, specifically to a mixing device for manufacturing art pigments. Background Technology

[0002] As a core material in art creation, education, and industrial decoration, art pigments directly affect the creative effect and application experience due to their color uniformity, texture fineness, and coloring stability. With the booming development of the cultural and creative industries, the market's quality requirements for art pigments continue to rise. They need to meet the stringent demands of professional creators for color accuracy and color mixing compatibility, while also adapting to the efficient and stable processing standards of large-scale production. The mixing process is a key step in the manufacturing of art pigments, directly determining the degree of dispersion of pigment particles and the consistency of component mixing, which in turn affects the smoothness of application, color reproduction, and storage stability of the pigments.

[0003] Most existing pigment mixing devices use a single stirring component (such as a toothed dispersion disc or a straight stirring blade) for unidirectional horizontal stirring. This type of stirring method generates significant centrifugal force during operation. Under the action of centrifugal force, some pigment raw materials are continuously pushed towards the inner wall of the container and accumulate, gradually moving away from the range of action of the stirring component. This results in a significant reduction in the contact frequency and contact time between the raw materials and the stirring component. In order to make the pigment reach the preset mixing standard, it is often necessary to extend the stirring time, which not only reduces the production efficiency, but also easily leads to pigment agglomeration and uneven mixing due to insufficient stirring in some areas, ultimately affecting the quality of the finished pigment. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a mixing device for manufacturing art pigments, so as to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mixing device for manufacturing art pigments, comprising a mixing tank, a storage tank at the top of the mixing tank, a bifurcated pipe at the bottom of the storage tank, a second motor installed at the bottom of the mixing tank, a stirring shaft connected to the output end of the second motor, a rotating ball fixed at the top of the stirring shaft, a diversion hole penetrating the outer surface of the rotating ball, one end of the bifurcated pipe extending into the interior of the rotating ball, a fixed blade fixed below the outer surface of the bifurcated pipe, rotating blades fixed to the inner wall of the rotating ball, a mounting plate and a slide rail fixed to the outer surface of the mixing tank, a first motor installed on one side of the mixing tank, a crankshaft installed on the inner side of the mounting plate, a connecting rod rotatably connected to the outer surface of the crankshaft, a push rod movably connected to one end of the connecting rod, a push plate fixed to one end of the push rod extending into the interior of the mixing tank, a gear fixed above the outer surface of the connecting rod, and a gear ring slidably connected to the outer surface of the slide rail via a sliding groove.

[0006] Furthermore, a guide rod is fixed to one side of the pusher plate, and both the guide rod and the pusher rod are movably connected to the mixing tank.

[0007] By adopting the above technical solution, and by setting a guide rod and a push rod to cooperate, a stable guide is provided for the lateral displacement of the push plate, so as to avoid its deviation or jamming during reciprocating motion, ensuring that the pushing action is accurate and efficient, and improving the stability of the device operation.

[0008] Furthermore, a combined sealing ring is provided at the contact gap between the guide rod and the push rod and the mixing tank, and a dynamic and static ring is provided at the contact gap between the stirring shaft and the mixing tank.

[0009] By adopting the above technical solution, a combined sealing ring (composed of elastic rubber (fluororubber) and wear-resistant ring (polytetrafluoroethylene)) is set at the contact point between the guide rod, push rod and mixing tank, which has both sealing and extrusion resistance capabilities. Dynamic and static rings are set at the contact point between the stirring shaft and the mixing tank, which can achieve reliable sealing under reciprocating motion and rotational motion respectively, effectively preventing pigment leakage and ensuring the sealing and safety of the device operation.

[0010] Furthermore, two sets of material control valves are provided above the outer surface of the bifurcated tube.

[0011] By adopting the above technical solution, the two sets of control valves can independently control the feeding rate of the two pigments, accurately match the target color ratio, avoid uneven mixing caused by feeding imbalance, and improve the accuracy and flexibility of pigment formulation.

[0012] Furthermore, a discharge port is provided below the outer surface of the mixing tank.

[0013] By adopting the above technical solution, the discharge port can quickly discharge the finished product after the pigment is evenly mixed.

[0014] Furthermore, the pusher plate is provided in four sets, and the other side of each of the four sets of pusher plates has a through hole.

[0015] By adopting the above technical solution, the four sets of pusher plates can push the edge pigments to the mixing area simultaneously from multiple directions; the through holes enable bidirectional flow of materials, avoid accumulation and stagnation on the back of the pusher plates, ensure that all pigments fully contact the mixing blades, and further improve the mixing uniformity and efficiency.

[0016] Furthermore, multiple sets of stirring blades are fixed to the outer surface of the stirring shaft, and the multiple sets of stirring blades are distributed at equal intervals from top to bottom.

[0017] By adopting the above technical solution, the stirring blades, which are evenly distributed from top to bottom, can cover different height areas inside the mixing tank, significantly improving the comprehensiveness and uniformity of the depth mixing.

[0018] Furthermore, the top of the mixing tank is provided with a control panel, which is electrically connected to the first motor and the second motor respectively.

[0019] By adopting the above technical solution, the control panel can centrally control the start / stop, speed and running time of the two motors, and flexibly adjust to meet the different pigment mixing requirements.

[0020] Furthermore, the crankshaft and gears are provided in four sets, the output end of the first motor is connected to the top of one set of crankshafts, and all four sets of gears mesh with the gear ring.

[0021] By adopting the above technical solution, the rotation of the first motor causes one of the crankshafts to rotate, which in turn causes a set of gears to rotate, thereby causing the gear ring to rotate. The rotation of the gear ring can drive the other gears and the crankshaft to rotate.

[0022] In summary, the present invention has the following main advantages: 1. This utility model, by incorporating a bifurcated pipe, a rotating ball, stirring blades, a stirring shaft, fixed blades, and rotating blades, allows operators to temporarily store two pigments to be mixed in two separate storage bins. By adjusting the control valves of the corresponding storage bins according to the target color mixing ratio, the two pigments are guided by the bifurcated pipe to gather and be injected into the rotating ball. Simultaneously, a second motor starts, driving the stirring shaft to rotate. The stirring shaft synchronously drives the stirring blades and the rotating ball to rotate. Under the mutual shearing and cooperation between the rotating blades on the inner wall of the rotating ball and the fixed blades at the end of the bifurcated pipe, the two pigments quickly achieve preliminary uniform mixing within the rotating ball, avoiding localized aggregation of a single pigment. The pre-mixed pigments are then evenly discharged to the subsequent mixing area through the diversion holes on the rotating ball, laying the foundation for subsequent deep mixing and improving the mixing effect and mixing efficiency. 2. This utility model, by incorporating a second motor, crankshaft, connecting rod, push rod, pusher plate, gear ring, gears, guide rail, and through holes, achieves the following: During the depth mixing stage, the second motor drives a set of crankshafts to rotate. These crankshafts, through gear meshing, drive the gear ring to rotate stably along the guide rail. The gear ring then drives the remaining gears to rotate synchronously, resulting in multiple crankshafts rotating collaboratively. During crankshaft rotation, the connecting rod reciprocates, and the push rod drives the pusher plate to move laterally back and forth, continuously pushing pigments accumulated at the container edge or far from the stirring blades towards the stirring blades' effective range. Simultaneously, the through holes on the pusher plate allow some pigments to flow through during the pushing process, preventing material accumulation on the back of the pusher plate. This ensures all pigments can circulate into the mixing area and fully contact the stirring blades. Combined with the rotation of the stirring blades, this completely solves the problem of insufficient mixing caused by materials easily moving away from the mixing components due to centrifugal force and localized accumulation in traditional mixing processes, significantly improving the uniformity and efficiency of depth mixing.

[0026] The embodiments of this utility model will be described below based on its overall structure.

One end of the push rod 14 extends into the interior of the mixing tank 1 and is fixed with a pusher plate 15. A gear 7 is fixed above the outer surface of the connecting rod 13. A gear ring 9 is slidably connected to the outer surface of the slide rail 12 through a slide groove 25. The crankshaft 6 and gear 7 are provided in four sets. The output end of the first motor 4 is connected to the top of one set of crankshafts 6. All four sets of gears 7 mesh with the gear ring 9. The rotation of the first motor 4 causes one type of crankshaft 6 to rotate, which in turn causes one set of gears 7 to rotate, thereby causing the gear ring 9 to rotate. The rotation of the gear ring 9 can drive the other gears 7 and the crankshaft 6 to rotate. A discharge port 10 is provided below the outer surface of the mixing tank 1. The discharge port 10 can quickly discharge the finished product after the pigment is evenly mixed.

[0028] See Figures 1-3 In the above embodiment, two sets of material control valves 24 are provided above the outer surface of the bifurcation pipe 23. The two sets of material control valves 24 can independently control the feeding rate of the two pigments, accurately match the target color ratio, avoid uneven mixing caused by feeding imbalance, and improve the accuracy and flexibility of pigment mixing.

[0029] See Figure 2 and Figure 4 In the above embodiment, the pusher plate 15 is provided in four sets, and the other side of the four sets of pusher plates 15 is provided with through holes 22. The four sets of pusher plates 15 can push the edge pigments to the stirring area simultaneously from multiple directions.

[0030] See Figures 2-3 In the above embodiment, multiple sets of stirring blades 21 are fixed on the outer surface of the stirring shaft 16, and the multiple sets of stirring blades 21 are equidistantly distributed from top to bottom. The equidistantly distributed stirring blades 21 from top to bottom can cover different height areas in the mixing tank 1, significantly improving the comprehensiveness and uniformity of depth mixing.

[0031] See Figure 1 In the above embodiment, the top of the mixing tank 1 is provided with a control panel 3. The control panel 3 is electrically connected to the first motor 4 and the second motor 11 respectively.

[0032] Example 2: To make the pusher plate move more smoothly when resetting, Example 2 is an improvement on Example 1. (See attached document.) Figure 1 , Figure 2 and Figure 4 A guide rod 8 is fixed on one side of the pusher plate 15, and both the guide rod 8 and the push rod are movably connected to the mixing tank 1.

This can achieve reliable sealing under reciprocating motion and rotational motion, effectively prevent pigment leakage, and ensure the sealing and safety of the device operation (the above sealing method is prior art and will not be described in detail here).

[0034] The implementation principle of this utility model is as follows: First, the two pigments to be mixed are stored in two storage tanks 2 respectively. By adjusting the two sets of material control valves 24 on the branch pipe 23, the two pigments are controlled to enter the rotating ball 17 through the branch pipe 23 according to the target ratio. At the same time, the second motor 11 is started, driving the stirring shaft 16 to rotate the rotating ball 17 and the stirring blades 21. The rotating blades 19 on the inner wall of the rotating ball 17 and the fixed blades 20 on the branch pipe 23 shear each other to achieve preliminary uniform mixing of the two pigments. The pigments after preliminary mixing are evenly discharged into the lower part of the mixing tank 1 through the diversion hole 18 on the rotating ball 17. The first motor 4 is started to drive one set of crankshafts 6 to rotate. Through the meshing transmission of gear 7 and gear ring 9, the other three sets of crankshafts 6 are driven to rotate synchronously. The crankshafts 6 drive the push rod 14 through the connecting rod 13 to drive the four sets of push plates 15 to reciprocate laterally, continuously pushing the pigments accumulated on the edge of the tank wall towards the stirring blades 21 area; the through holes 22 on the push plates 15 The system allows some pigment to flow back to avoid accumulation on the back. In conjunction with the rotation and stirring of multiple sets of equally spaced stirring blades 21 on the stirring shaft 16, the pigments are fully contacted and mixed. Finally, the uniformly mixed pigments are discharged through the discharge port 10.
