Description

Technical Field

[0001] This utility model relates to the field of mixing technology, and in particular to a mixing device for preparing impregnation solution. Background Technology

[0002] Impregnation solutions are key formulations widely used in composite materials, textile coatings, and electronic material packaging. Their performance directly determines the bonding strength, uniformity, and functionality of the final product. These liquids are usually made by mixing raw materials such as polymer resins, curing agents, solvents, and various functional additives (such as plasticizers and flame retardants) in precise proportions. The raw materials often have large differences in density and viscosity, poor compatibility, and physical changes and chemical reactions may occur during the mixing process. Therefore, extremely high requirements are placed on the uniformity, efficiency, and process control of the mixing.

[0003] Traditional mixing devices often employ fixed agitators that operate in a single rotation mode. This simple mixing method easily creates a stable flow field within the mixing drum, leading to stratification of raw materials with different densities. High-viscosity materials tend to deposit in dead corners on the drum walls or at the bottom, making it difficult to achieve uniform dispersion at the microscale. For multi-component systems like impregnation solutions, uneven mixing directly results in batch-to-batch quality fluctuations, causing problems such as poor local curing, coating defects, or substandard performance, severely impacting the final product's yield.

[0004] Therefore, developing a mixing device that can reduce dead zones, has a high degree of automation, and is stable and reliable in operation is of urgent practical significance for meeting the production needs of high-performance impregnation liquid, improving product quality and production efficiency.

[0027] 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.

[0028] A mixing device for preparing an impregnation solution, such as Figures 1 to 5As shown, the device includes a mixing cylinder 1. A top plate 17 is bolted to the top outer wall of the mixing cylinder 1. A bracket 2 is bolted to the top outer wall of the top plate 17. A hollow tube 22 is rotatably connected to a through hole on the surface of the bracket 2. The hollow tube 22 is driven by a driving component. A support component is fixed to the bottom of the hollow tube 22. An upright plate 25 is fixed to the support component. A rotating shaft 26 is rotatably connected between two upright plates 25. A servo motor 20 is fixed to one side of the outer wall of the upright plate 25 by screws. The output end of the servo motor 20 is connected to one end of the rotating shaft 26 through a coupling. A mounting base 23 is fixed to the outer circumference of the rotating shaft 26. A rotary stirring mechanism is mounted on the top of the mounting base 23.

[0029] During the preparation of raw materials, multiple raw materials are mixed together. During mixing, multiple raw materials are introduced into the mixing cylinder 1 according to the ratio. The hollow tube 22 is driven to rotate relative to the support 2 by the driving component. The servo motor 20 can drive the mounting base 23 and the rotating shaft 26 to rotate relative to the vertical plate 25, thereby adjusting the tilt angle of the rotating stirring mechanism.

[0030] When the axis of the rotary stirring mechanism and the axis of the hollow tube 22 coincide, the rotary stirring mechanism mixes various raw materials near the middle of the mixing cylinder 1 in the vertical direction. To improve the uniformity of mixing, the servo motor 20 drives the mounting base 23 and the rotating shaft 26 to rotate at a certain angle relative to the vertical plate 25. The rotary stirring mechanism is tilted at a certain angle relative to the hollow tube 22. The rotary stirring mechanism is tilted relative to the inside of the mixing cylinder 1 to mix various raw materials. At the same time, when the driving component drives the hollow tube 22 to rotate, the rotary stirring mechanism revolves around the axis of the hollow tube 22 and rotates on its own axis, so that the rotary stirring mechanism mixes the raw materials in the area near the inner wall of the mixing cylinder 1, improving the uniformity of mixing various raw materials inside the mixing cylinder 1 and ensuring the mixing effect.

[0031] The top outer wall of the top plate 17 is welded with a feeding pipe 8, and the top of the feeding pipe 8 is threadedly connected with a cover plate 9.

[0032] After the cover plate 9 is removed from the top of the feed pipe 8, various raw materials are poured into the mixing cylinder 1 through the container via the feed pipe 8. After the raw materials are poured in, the cover plate 9 and the feed pipe 8 are connected by threads, and the feed pipe 8 is sealed by the cover plate 9.

[0033] The rotary stirring mechanism includes a stirring blade 7, a stirring rod 18, and a servo motor 21. The servo motor 21 is fixed to the top outer wall of the mounting base 23 by screws, and the stirring rod 18 is fixed to the output end of the servo motor 21. The stirring blade 7 and the stirring rod 18 are welded together.

[0034] The stirring rod 18 and stirring blade 7 are driven to rotate by a servo motor 321, and the stirring blade 7 and stirring rod 18 are used to stir and mix the various raw materials inside the mixing cylinder 1.

[0035] The driving component includes a servo motor 10, a pulley 14, and a synchronous belt 15. The servo motor 10 is fixed to the top outer wall of the bracket 2 by screws. The two synchronous belts 15 are respectively fixed to the outer circumference of the hollow tube 22 and the output end of the servo motor 10, and the two synchronous belts 15 are driven by the pulley 14.

[0036] By utilizing the transmission action of pulley 14 and synchronous belt 15, servo motor 10 can indirectly drive hollow tube 22 to rotate.

[0037] The bracket 2 has a mounting frame 3 fixed to its top outer wall by screws, and a mounting shell 13 fixed to its top inner wall by screws. A carbon brush 27 is mounted on the mounting shell 13. A wiring shell 30 is fixed to the top of the hollow tube 22 by screws, and a slip ring 16 is fixed to the top of the wiring shell 30 by screws.

[0038] The carbon brush 27 is used in conjunction with the slip ring 16, which is fixed to the wiring housing 30 at the top of the hollow tube 22 and rotates accordingly. The carbon brush 27 inside the mounting housing 13 maintains sliding contact with the slip ring 16, so as to stably transmit power to the servo motor 20 and servo motor 21 fixed on the rotating part while the hollow tube 22 continues to rotate. The wiring housing 30 is equipped with a terminal that is electrically connected to the carbon brush 27, so as to provide power to the servo motor 20 and servo motor 21 through an external power supply after wiring, thus avoiding the wire from getting tangled or wrapped during the rotation of the hollow tube 22.

[0039] The support includes a turntable 12 and a turntable 29. The turntable 12 is welded to the bottom outer wall of the hollow tube 22, and the turntable 29 is welded to the bottom outer wall of the turntable 12 via a vertical rod 24. A rotating seat 29 is rotatably connected to the top of the top plate 17. The rotating seat 29 and the turntable 29 are fixed together by a connecting piece 28. A telescopic corrugated tube 11 is fixed between the bottom of the mounting base 23 and the top of the rotating seat 29 by an adhesive bonding method.

[0040] The rotating seat 29 and the turntable 19 are connected by a connecting piece 28, so that the turntable 19 and the rotating seat 29 can rotate synchronously. The connecting piece 28 and the turntable 19 can be fixed to the rotating seat 29 by screws. The telescopic corrugated pipe 11 ensures the sealing between the mounting base 23 and the rotating seat 29. At the same time, the mounting base 23 has a certain amount of movement relative to the vertical plate 25, so that the tilt angle of the rotating stirring mechanism relative to the inside of the mixing cylinder 1 can be adjusted.

[0041] The bottom of the mixing cylinder 1 is welded with a discharge pipe 4, and a solenoid valve 5 is fixed to the bottom outer wall of the discharge pipe 4 by bolts.

[0042] After the various raw materials are mixed, the solenoid valve 5 is opened, allowing the mixed raw materials to be discharged through the solenoid valve 5.

[0043] A controller 6 is installed on the side of the mixing cylinder 1;

[0044] The controller 6 is electrically connected to the servo motor 10, servo motor 20, servo motor 3 21 and solenoid valve 5 through control lines. It is used to programmatically control the servo motor 10 to drive the rotation of the hollow tube 22, the servo motor 20 to adjust the tilt angle of the rotating stirring mechanism, the servo motor 3 21 to drive the rotation of the stirring blade 7, and the opening and closing of the solenoid valve 5, so as to complete the mixing and discharging process automatically.

[0045] Working principle: The controller 6 programs and controls the servo motor 10 to drive the hollow tube 22 and the support connected thereto to rotate through the pulley 14 and the synchronous belt 15. At the same time, it controls the servo motor 20 to drive the rotating shaft 26 to adjust the tilt angle of the rotating stirring mechanism on the mounting base 23, and controls the servo motor 3 21 to drive the stirring blade 7 to rotate. The stirring blade 7 can efficiently and uniformly mix the raw materials in the center and edge areas of the mixing cylinder 1. After the mixing is completed, the controller 6 starts the solenoid valve 5 to discharge the material through the discharge pipe 4.

[0046] 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.
