Description

Technical Field

[0001] This utility model relates to the field of chemical raw material processing technology, and in particular to a uniform stirring device for polyurethane composite materials. Background Technology

[0002] Polyurethane blends, as an important chemical raw material, play a crucial role in the manufacture of polyurethane foams, coatings, elastomers, and other products. Their mixing uniformity has a decisive impact on the performance and quality of the final product. In particular, the mixing process is critical in the preparation of polyurethane blends, ensuring thorough mixing of raw materials and achieving the desired properties. However, existing mixing technologies and equipment are increasingly revealing significant limitations when processing polyurethane blends.

[0003] Specifically, utility model patent CN 211988087 U discloses a uniform mixing device for processing polyurethane composite materials. This device includes a complex structure comprising a mixing tank, an annular rotating plate, a tilting plate, connecting components, a circulation pipe, and a circulation assembly. Raw materials are added through a feeding pipe on the top cover, and the circulation pipe and circulation assembly circulate and mix the materials inside the mixing tank. Simultaneously, the tilting and spreading components assist in the mixing. While this design improves mixing efficiency to some extent, it still has significant shortcomings.

[0004] First, the mixing cylinder of this device cannot move; it relies solely on the stirring structure for mixing. This single stirring method is insufficient to fully stimulate the mixing activity of the raw material liquid, potentially leading to incomplete mixing in certain areas during the mixing process. Second, due to the fixed nature of the mixing cylinder, the flow path of the raw material during stirring is relatively fixed, preventing the formation of multi-angle and multi-layered mixing effects, thus affecting the thoroughness and uniformity of the mixing.

[0005] Therefore, to address the shortcomings of existing technologies, we urgently need a polyurethane blend uniform mixing device to solve this problem. This mixing device should enable the mixing drum itself to move, forming a multi-dimensional mixing method in conjunction with the mixing structure. This would significantly improve the mixing activity, thoroughness, and uniformity of the raw material liquid, while better meeting the needs of modern production and providing strong support for the sustainable development of the polyurethane blend industry.

[0023] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0024] Example 1

[0025] Please see Figure 1-5 As shown, a polyurethane blend uniform mixing device of this embodiment includes a mixing cylinder 1, a rotating seat 3, and a rotating shaft 2. The mixing cylinder 1 is equipped with a mixing structure inside. A feed pipe is connected to one side of the top of the mixing cylinder 1, and a discharge pipe is connected to one side of the bottom. The rotating shaft 2 is rotatably connected inside the rotating seat 3. Both sides of the bottom of the mixing cylinder 1 are connected to the top of the rotating shaft 2 through a connecting structure. Both sides of the rotating seat 3 are provided with side plates 4. Each side plate 4 is provided with a roller seat 12 at its top. A roller 13 that contacts the side wall of the mixing cylinder 1 is rotatably connected inside the roller seat 12. The bottom of the roller seat 12 is connected to the side plate 4 through a lifting assembly.

[0026] First, the raw materials of the polyurethane composite are slowly poured into mixing cylinder 1 through the feed pipe connected to one side of the top. At this time, mixing cylinder 1 is stationary, ready for the subsequent mixing process. The rotating shaft 2 is rotatably connected to the inside of the rotating seat 3, and the bottom sides of mixing cylinder 1 are connected to the top of the rotating shaft 2 through a connecting structure. This connection method ensures that the rotational power of the rotating shaft 2 can be transmitted to mixing cylinder 1, but mixing cylinder 1 does not directly rotate with the rotating shaft 2, but is in a state of swaying preparation awaiting activation.

[0027] Next, the roller seats 12 located on the side plates 4 on both sides of the rotating base 3 begin to play a crucial role. Rollers 13 are rotatably connected inside the roller seats 12, and these rollers 13 are in close contact with the side wall of the mixing cylinder 1. Through fine adjustment of the lifting assembly, the roller seats 12 can move up and down, thereby driving the rollers 13 to apply a vertical force to the mixing cylinder 1.

[0028] As the lifting assembly slowly raises the roller seat 12, the roller 13 presses tightly against the side wall of the mixing drum 1. Due to the rotation of the roller 13 and the force transmitted from the rotating shaft 2 to the mixing drum 1, the mixing drum 1 begins to rhythmically sway left and right inside the rotating seat 3. This swaying is not a simple rocking motion, but rather, with the precise coordination of the rotating shaft 2, it forms a multi-dimensional, rhythmic motion pattern, allowing the raw materials inside the mixing drum 1 to be fully subjected to the dual effects of stirring and swaying.

[0029] While the mixing drum 1 is shaking, the stirring structure inside it also begins to work efficiently, directly mixing the raw materials. The rotation of the stirring structure and the shaking of the mixing drum 1 work together to create a synergistic effect. This synergistic effect results in a complex flow path for the raw materials within the mixing drum 1, fully stimulating the liquid material and greatly enhancing the mixing activity, thus ensuring thorough mixing of the raw materials.

[0030] After a period of thorough mixing, when the raw materials reach the predetermined degree of uniformity, the mixed polyurethane composite material is smoothly discharged through the discharge pipe connected to one side of the bottom of the mixing cylinder 1, thus completing the entire mixing process.

[0031] Example 2

[0032] Please see Figure 1-5 As shown in this embodiment, a polyurethane blend uniform mixing device includes a stirring rod 9 disposed inside a mixing cylinder 1 and a drive motor 6 installed at one end of the mixing cylinder 1. The output shaft of the drive motor 6 is connected to one end of the stirring rod 9. Specifically, after the drive motor 6 is started, its output shaft drives the stirring rod 9 to rotate inside the mixing cylinder 1, directly mixing the raw materials. The rotational motion of the stirring rod 9 and the shaking motion of the mixing cylinder 1 work together to form a synergistic effect. This synergistic effect creates a more complex flow path for the raw materials within the mixing cylinder 1, ensuring thorough mixing of the liquid raw materials, greatly improving mixing uniformity and efficiency, and ensuring that the raw materials reach the predetermined mixing uniformity in a short time.

[0033] Several support legs 8 are connected to the bottom of the rotating base 3 and the bottom of the two side plates 4. Specifically, the support legs 8 are connected to the bottom of the rotating base 3 and the bottom of the two side plates 4, providing stable support for the entire device. The design of the support legs 8 enhances the stability and load-bearing capacity of the device, ensuring that the device will not tip over or be damaged due to shaking or vibration during the stirring process, thus improving the safety and reliability of the device.

[0034] Example 3

[0035] Please see Figure 1-5As shown in the figure, a polyurethane blend uniform mixing device of this embodiment includes a connecting structure comprising an inclined connecting bracket 7. One end of the connecting bracket 7 is connected to a mounting ring 5 bolted to the outer ring of the mixing cylinder 1, and the other end is connected to the side wall of the rotating shaft 2. Specifically, one end of the connecting bracket 7 is bolted to the mounting ring 5 on the outer ring of the mixing cylinder 1, and the other end is connected to the side wall of the rotating shaft 2. This connection method ensures that the rotational power of the rotating shaft 2 can be transmitted to the mixing cylinder 1, but allows the mixing cylinder 1 to sway inside the rotating seat 3. The design of the connecting structure not only ensures the power transmission between the rotating shaft 2 and the mixing cylinder 1, but also realizes the swaying motion of the mixing cylinder 1, providing the possibility for multi-dimensional mixing methods and further improving the mixing uniformity of the raw materials.

[0036] The lifting assembly includes a lifting cylinder 10 mounted on the bottom side of the side plate 4. The output end of the lifting cylinder 10 slides through the side plate 4 and connects to the bottom of the roller seat 12. Specifically, after the lifting cylinder 10 is activated, its output end slides through the side plate 4 and connects to the bottom of the roller seat 12, pushing the roller seat 12 to rise or fall. The fine adjustment of the lifting cylinder 10 allows the roller seat 12 to move up and down, thereby driving the roller 13 to apply a vertical force to the mixing cylinder 1, controlling the swaying amplitude and frequency of the mixing cylinder 1, and further improving the uniformity and efficiency of mixing.

[0037] Guide rods 11, with one end sliding through the side plate 4, are fixedly connected to both sides of the bottom of the roller seat 12. Specifically, the guide rods 11 are fixed to both sides of the bottom of the roller seat 12, with one end sliding through the side plate 4, providing guidance and support for the up-and-down movement of the roller seat 12. The design of the guide rods 11 enhances the stability and accuracy of the roller seat 12 during up-and-down movement, prevents the roller seat 12 from shifting or tilting during movement, ensures close contact and uniform force application between the roller 13 and the side wall of the mixing cylinder 1, and further improves the uniformity of mixing and the reliability of the device.

[0038] This solution includes the following workflow:

[0039] First, the raw materials of the polyurethane composite are slowly poured into the mixing cylinder 1 through the feed pipe connected to one side of the top. At this time, the mixing cylinder 1 is stationary. Next, the drive motor 6 starts, and its output shaft drives the stirring rod 9 to rotate inside the mixing cylinder 1, directly stirring and mixing the raw materials. At the same time, the lifting cylinder 10 is activated, pushing the roller seat 12 upward, and the roller 13 presses tightly against the side wall of the mixing cylinder 1. Due to the rotation of the roller 13 and the force transmitted from the rotating shaft 2 to the mixing cylinder 1, the mixing cylinder 1 begins to rhythmically sway left and right inside the rotating seat 3. This swaying, in conjunction with the rotational movement of the stirring rod 9, forms a synergistic effect, resulting in a complex flow path for the raw materials within the mixing cylinder 1, and the raw material liquid is fully stimulated.

[0040] Beneficial Effects: This device achieves a synergistic effect through the rotation of the stirring rod 9 and the shaking of the mixing cylinder 1, significantly improving the uniformity and efficiency of raw material mixing. The design of the connecting bracket 7 and the mounting ring 5 ensures power transmission between the rotating shaft 2 and the mixing cylinder 1 while also enabling the shaking motion of the mixing cylinder 1, allowing for multi-dimensional mixing methods. The design of the support legs 8 enhances the stability and load-bearing capacity of the device, ensuring that it will not tip over or be damaged due to shaking or vibration during mixing. The fine adjustment of the lifting cylinder 10 allows the roller seat 12 to move up and down, thereby driving the roller 13 to apply a vertical force to the mixing cylinder 1, controlling the shaking amplitude and frequency of the mixing cylinder 1. The design of the guide rod 11 enhances the stability and accuracy of the roller seat 12 during up and down movement, preventing the roller seat 12 from shifting or tilting during movement, and ensuring close contact and uniform force application between the roller 13 and the side wall of the mixing cylinder 1. Overall, the device has the advantages of reasonable structure, simple operation, high mixing uniformity and high efficiency, and is suitable for uniform mixing of polyurethane composite materials.
