Description

Technical Field

[0001] This utility model relates to the field of polymer material processing equipment technology, and in particular to a dispersion and mixing device for functional organic clay for high tensile strength polymers. Background Technology

[0002] In the preparation of high tensile strength polymers, functional organoclay, as a key modifying component, directly determines the mechanical properties of the final product through its dispersion and mixing effect with the polymer matrix. Currently, the dispersion and mixing devices commonly used in the industry are mostly a combination of a fixed stirring shaft and a positioning dispersion and mixing tank. The specific operation process is as follows: First, the dispersion and mixing tank containing functional organoclay and polymer raw materials is precisely placed directly below the stirring shaft, ensuring that the axis of the stirring shaft is aligned with the center of the mixing tank. Then, the stirring shaft is controlled to descend vertically, allowing the stirring blades to fully extend into the raw materials inside the dispersion and mixing tank. Finally, the drive mechanism is activated to rotate the stirring shaft, thereby achieving dispersion, mixing, and stirring of the raw materials.

[0003] However, the aforementioned existing devices have significant drawbacks in practical applications, making it difficult to meet the stringent requirements of high tensile strength polymers for uniform mixing of raw materials: Low mixing efficiency: Since the dispersing mixing tank is always in a fixed position, the mixing area of ​​the mixing shaft is limited to the range covered by its rotation trajectory. For the edge areas and bottom corners of the mixing tank that are far from the mixing shaft, the mixing blades cannot work effectively, resulting in the formation of "mixing blind zones" in the tank. It is necessary to extend the mixing time to barely achieve a basic mixing effect, which greatly reduces production efficiency.

[0004] Poor mixing effect: The fixed mixing zone means that the raw materials can only move in a circular motion around the mixing axis during the mixing process. The overall fluidity is poor, which can easily lead to problems such as functional organic clay agglomerates not being effectively dispersed and local raw material mixing ratio imbalance, thus affecting the tensile strength stability of subsequent polymer products.

[0005] Insufficient adaptability: The fixed structure design of the existing equipment makes it difficult to adjust the stirring contact range according to different batches and viscosities of high tensile strength polymer raw materials. When dealing with high viscosity raw materials, the stirring resistance increases, which further aggravates the problem of uneven mixing and cannot meet the diverse production needs. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a functional organic clay dispersion and mixing device for high tensile strength polymers with high stirring efficiency, good mixing effect and strong adaptability.

[0007] This utility model discloses a dispersion and mixing device for functional organic clay used in high tensile strength polymers, comprising a base, a lifting support mechanism on one side of the top of the base, a stirring mechanism on the top of the lifting support mechanism, a stirring rod assembly vertically mounted at one end of the stirring mechanism, a stirring tank placed directly below the stirring rod assembly, and a clamping mechanism adapted to the placement position of the stirring tank, and further comprising: The displacement plate slides tightly against the top of the base; The top of the connecting plate and the base is provided with a mounting groove, and the two ends of the connecting plate are respectively connected to the two opposite side walls of the mounting groove. A fixing plate is located in the mounting groove and at the bottom of the displacement plate. The bottom of the fixing plate is connected to the top center of the connecting plate. An adjusting threaded rod is rotatably mounted on the fixing plate. The stepper motor is mounted on the outer wall of the base. The output end of the stepper motor rotates through the side wall of the base and extends into the mounting slot. The output end of the stepper motor is coaxially connected to the adjusting threaded rod. The stepper motor is equipped with a driver and a controller. The driving block has an adjustment threaded hole through its side wall. The driving block is threadedly connected to the adjustment threaded rod through the adjustment threaded hole. The top of the driving block is connected to the bottom of the displacement plate near the stepper motor. The mixing tank is placed on the support assembly at the top of the displacement plate.

[0008] Furthermore, the support component includes a turntable and a power mechanism. The power mechanism is installed at the bottom center of the displacement plate. The output end of the power mechanism rotates from bottom to top through the displacement plate and is concentrically connected to the bottom of the turntable. A clamping mechanism is installed on the turntable, and the mixing tank is placed on the top of the turntable under the limitation of the clamping mechanism.

[0009] Furthermore, the mounting groove is provided with two guide shafts arranged parallel to the adjusting threaded rod. Each set of guide shafts is slidably fitted with a stabilizing ring. Both sets of stabilizing rings are connected to the bottom end of the displacement plate, and both sets of stabilizing rings are located on the same side as the driving block.

[0010] Furthermore, a number of omnidirectional balls are evenly distributed at the top of the displacement plate to support the turntable.

[0011] Furthermore, it also includes an auxiliary ramp, which is mounted on the base via a sliding assembly. The bottom of the mixing tank is equipped with several casters, and the auxiliary ramp is used to assist in loading and unloading the mixing tank on the turntable.

[0012] Furthermore, the sliding assembly includes two sets of slide rails, which are installed at both ends of the side wall of the base away from the lifting support mechanism. Sliders are slidably mounted on both sets of slide rails, and driving rods are mounted on both sets of sliders. The driving rods are respectively connected to the two opposite side walls of the auxiliary slope plate. Anti-detachment blocks are provided at the ends of both sets of slide rails to prevent the sliders from slipping off the slide rails.

[0013] Furthermore, the auxiliary slope plate is provided with an arc-shaped groove that matches the shape of the turntable at the part near the turntable, and the arc-shaped groove area of ​​the auxiliary slope plate is set at the same height as the turntable.

[0014] Furthermore, the power mechanism is configured as a motor with a speed reducer.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Significantly improved mixing efficiency: The stepper motor drives the adjusting threaded rod, which in turn moves the displacement plate along the base. Combined with the power mechanism, the turntable rotates the mixing drum, breaking the limitations of the traditional "fixed stirring shaft + fixed mixing drum". This allows the stirring rod assembly to cover more areas inside the mixing drum, eliminating "blind spots" in the mixing process. Mixing can be completed without extending the mixing time, greatly improving production efficiency. 2. Significantly optimized mixing effect: The linear movement of the displacement plate and the circular rotation of the turntable form a compound motion, which promotes the full flow of raw materials in the mixing tank, effectively breaks up functional organic clay agglomerates, avoids local raw material mixing ratio imbalance, ensures the stability of the tensile strength of subsequent polymer products, and meets the stringent requirements of high tensile strength polymers for the uniformity of raw material mixing. 3. Enhanced adaptability: With the help of the stepper motor's driver and controller, the moving speed and distance of the displacement plate can be precisely adjusted. Combined with the control of the turntable speed by the power mechanism, the stirring contact range can be adjusted according to different batches and different viscosities of high tensile strength polymer raw materials. When dealing with high viscosity raw materials, the stirring resistance can be reduced to meet diverse production needs. 4. Improved ease of operation and stability: The guide shaft and stabilizing ring work together to ensure smooth sliding of the displacement plate, and the universal ball provides auxiliary support for the turntable, reducing friction and shaking during turntable rotation; the auxiliary slope plate works with the universal wheels at the bottom of the mixing tank to facilitate loading and unloading of the mixing tank, while the arc groove design ensures precise docking of the mixing tank and the turntable during loading and unloading, significantly enhancing the overall structural stability and ease of operation.

[0023] The auxiliary slope plate 17 is provided with an arc-shaped groove 22 that matches the shape of the turntable 12 at the part near the turntable 12, and the arc-shaped groove 22 area of ​​the auxiliary slope plate 17 is set at the same height as the turntable 12.

[0024] The working principle of this utility model is as follows: When the device is working, first adjust the position of the auxiliary slope plate 17 by sliding component, and use the universal wheels at the bottom of the mixing tank 5 to push the mixing tank 5 containing functional organic clay and polymer raw materials along the auxiliary slope plate 17 to the top of the turntable 12. The mixing tank 5 is limited and fixed by clamping mechanism 6, and then the auxiliary slope plate 17 is adjusted to reset.

[0025] The lifting support mechanism 2 is activated, causing the stirring mechanism 3 and stirring rod assembly 4 to descend vertically, allowing the stirring rod assembly 4 to extend into the raw materials inside the stirring tank 5. Next, the stepper motor 10 and power mechanism 13 are activated: the stepper motor 10 is controlled to rotate via a driver and controller, driving the adjusting threaded rod to rotate. The adjusting threaded rod, through threaded transmission, drives the driving block 11 to move along the guide shaft 14, thereby causing the displacement plate 7, the top turntable 12, and the stirring tank 5 to slide smoothly along the base 1. Simultaneously, the power mechanism 13 drives the turntable 12 to rotate, causing the stirring tank 5 to perform circular motion. During this control process, under the coordinated control of the driver and controller, the stepper motor 10 rotates at a certain angle at preset intervals, thus achieving the effect of the stirring tank 5 on the displacement plate 7 moving a certain distance at regular intervals. During this control process, the turntable 12 drives the stirring tank 5 to rotate continuously. After the displacement plate 7 moves to one end, the stepper motor 10 rotates in the opposite direction, achieving the effect of reciprocating movement of the stirring tank 5 on the displacement plate 7. The linear movement of the displacement plate 7 and the circular rotation of the turntable 12 form a compound motion, which enables the stirring rod assembly 4 to fully act on all areas inside the mixing tank 5, promoting the full flow and mixing of raw materials, effectively breaking up agglomerates, and eliminating blind spots in the stirring process.

[0026] After mixing is completed, the stepper motor 10 and power mechanism 13 are turned off. The stirring rod assembly 4 is driven to rise and detach from the mixing tank 5 by the lifting support mechanism 2. The clamping mechanism 6 is released, and the mixing tank 5 is moved out by the auxiliary slope plate 17 and casters, thus completing one dispersion and mixing operation.
