Technical Field

[0001] This utility model relates to the field of treatment agent mixing technology, specifically a mixing device for automotive interior surface treatment agents. Background Technology

[0002] Automotive interior design encompasses the design and functionality of a car's interior space, directly impacting driving and passenger comfort, safety, and aesthetics. Automotive interior surface treatment agents are primarily used to protect and enhance interior components, improving their durability, appearance, and stain resistance. These agents typically consist of resins, solvents, additives, and fillers. The varying densities and viscosities of these components necessitate stirring to prevent layering, sedimentation, or clumping, ensuring uniform distribution and stable performance.

[0003] Traditional stirring rods have low mixing efficiency for high-viscosity materials, are prone to stratification or localized solidification, and are inconvenient to operate when manually cleaning because the stirring rod assembly is located inside the mixing container. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a stirring device for automotive interior surface treatment agent, including a stirring container 1 and a cover plate 2. The cover plate 2 is provided with a vacuum hole 21, which is connected to a vacuum tube 22. The vacuum tube 22 is connected to a vacuum pump assembly. A first motor 3 is installed at the top of the cover plate 2. The first motor 3 is connected to a stirring assembly 4. The stirring assembly 4 includes a stirring rod 41, which is provided with a spiral stirring blade 42 and an anchor stirring blade 43. The cover plate 2 is driven by a linear drive assembly 5, which is installed on a base frame 6. A limit frame 7 is installed on the base frame 6.

[0024] When the spiral stirring blade 42 rotates, it generates shear force, which in turn generates axial flow, propelling the fluid along the longitudinal direction of the stirring container 1. At the same time, the shear force disperses the material. The anchor stirring blade 43 generates radial flow and part of the axial flow through rotation. The stirring assembly 4 integrates the spiral stirring blade 42 and the anchor stirring blade 43 into one unit. When used in combination, it takes into account both radial and axial flow, giving full play to the advantages of both and making up for the limitations of a single design. The combined design optimizes fluid flow, makes the motor load more balanced, and improves the stirring quality while reducing energy consumption.

[0025] During stirring, the cover plate 2 moves down and seals with the stirring container 1. The vacuum pump assembly operates and evacuates the stirring container 1 through the vacuum tube 22. Under vacuum conditions, the fluid viscosity dynamically decreases, improving the uniformity of mixing and thus increasing the stirring efficiency. A negative pressure threshold is set, and the pressure inside the stirring container 1 is monitored in real time by the vacuum sensor 24. When the pressure inside the stirring container 1 reaches the preset vacuum level and stabilizes, the vacuum pump automatically stops. After the stirring time is over, the vacuum pump is turned off and the pressure is released through the pressure relief port 25.

[0026] The linear drive assembly 5 includes a U-shaped frame 51, a second motor 52 is mounted on the top of the U-shaped frame 51, the output shaft of the second motor 52 is fixedly connected to the lead screw 53, a slide rod 54 is provided on the U-shaped frame 51, and the slide rod 54 is located on one side of the lead screw 53. Both the lead screw 53 and the slide rod 54 pass through the slide seat 55, and the slide seat 55 and the slide rod 54 are slidably connected.

[0027] When the second motor 52 is working, it drives the lead screw 53 at one end to rotate, which in turn drives the slide block 55 to slide along the slide rod 54. The slide block 55 drives the cover plate 2 to move synchronously, and the cover plate 2 drives the stirring assembly 4 to move synchronously, thereby adjusting the height of the stirring assembly 4. During stirring, the stirring assembly 4 is driven to move down through the linear drive assembly 5 and extend into the stirring container 1. After stirring is completed, the stirring assembly 4 is driven to move up through the linear drive assembly 5 to remove the stirring assembly 4 from the stirring container 1, thereby transferring the stirring container 1 and cleaning the stirring assembly 4. The stirring container 1 can be directly used as a treatment agent storage tank, which is convenient for unloading and cleaning the stirring assembly 4.

[0028] The mixing container 1 is limited by the limiting frame 7, so that when the mixing container 1 is placed, it can be positioned directly below the cover plate 2, and the mixing container 1 can be quickly positioned when it is replaced.

[0029] The linear drive assembly 5 has a slide 55 fixedly connected to the cover plate 2. The cover plate 2 is equipped with a vacuum sensor 24 and a pressure relief port 25. The vacuum sensor 24 monitors the pressure inside the stirring container 1 in real time. A valve is installed at the pressure relief port 25. The valve can be a solenoid valve to automatically control the opening and closing of the pressure relief port 25.

[0030] The lower end face of the cover plate 2 is provided with a sealing ring 23, which improves the sealing between the mixing container 1 and the cover plate 2.

[0031] One end of the stirring rod 41 is fixedly provided with a screw 44.

[0032] The output shaft of the first motor 3 is fixedly connected to the threaded sleeve 31 via a coupling.

[0033] The screw sleeve 31 is threadedly fixed to the screw rod 44, and the screw sleeve 31 is detachably connected to the stirring assembly 4. The stirring assembly 4 can be removed separately, making it convenient to replace and maintain the stirring assembly 4.

[0034] The cover plate 2 is located directly above the mixing container 1, and the mixing container 1 can be opened and closed through the cover plate 2.

[0035] The stirring component 4 extends into the stirring container 1 and rotates under the drive of the first motor 3 to perform stirring.

[0036] Working principle: During use, the materials to be mixed are added into the mixing container 1. The linear drive assembly 5 drives the cover plate 2 and the mixing assembly 4 to move down, sealing the cover plate 2 with the mixing container 1. The mixing assembly 4 is placed into the mixing container 1. The vacuum pump assembly works, and the mixing container 1 is evacuated through the vacuum tube 22. The pressure inside the mixing container 1 is monitored in real time by the vacuum sensor 24. When the pressure inside the mixing container 1 reaches the preset vacuum level and stabilizes, the vacuum pump automatically stops. The first motor 3 works to drive the mixing assembly 4 to rotate, mixing the materials in the mixing container 1. When the mixing time is over, the vacuum pump is turned off and the pressure is released through the pressure relief port 25. The linear drive assembly 5 drives the mixing assembly 4 to move up, removing the mixing assembly 4 from the mixing container 1. The mixing container 1 is then transferred to a new mixing container 1 and placed in the mixing position. The limiting frame 7 limits the mixing container 1, preparing it for the next mixing operation.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
