[0002] In the production process of PVC flooring, the mixing effect of raw materials plays a decisive role in product quality.

[0003] Currently, most existing mixing devices employ a simple single-shaft stirring structure, relying on a single stirring blade to mix various raw materials such as PVC resin, plasticizer, stabilizer, and filler. Due to this singular stirring method, it is difficult for different raw materials to achieve sufficient blending during the mixing process. For example, plasticizers may not be able to uniformly coat PVC resin particles, leading to defects in PVC flooring during subsequent processing and molding, such as uneven hardness and unstable mechanical properties, which seriously affect the quality and service life of the product.

[0004] In view of the above problems, this application proposes a raw material mixing device for the production of PVC flooring to improve the above problems. Utility Model Content

[0026] Please see the appendix Figures 1 to 4As shown, this utility model provides a raw material mixing device for PVC flooring production, including a tank 10. A fixing block 11 is fixed to the upper end of the tank 10. A reduction motor 12 is fixed to the upper end of the tank 10 and to one side of the fixing block 11. A first gear 13 is fixed to the output end of the reduction motor 12 and is rotatably connected to one side inside the fixing block 11. A second gear 14 is rotatably connected to the lower end inside the fixing block 11. The second gear 14 is located below the first gear 13 and meshes with the first gear 13. A first rotating shaft 15 is fixed to the lower end of the second gear 14. The first rotating shaft 15 passes through the lower end of the fixing block 11 and extends into the interior of the tank 10. Multiple first stirring rods 16 are fixed on the outside of the first rotating shaft 15 and inside the tank 10. The interior of the fixing block 11 is rotatably connected to the second rotating shaft 17, and the lower end of the second rotating shaft 17 passes through the lower end of the first rotating shaft 15. The outside of the second rotating shaft 17 and inside the fixing block 11 is fixed to the third gear 18, which meshes with the first gear 13. Multiple second stirring rods 19 are fixed on the lower end of the outside of the second rotating shaft 17, and the multiple second stirring rods 19 are located inside the tank 10.

[0027] In this embodiment, during operation, when the reduction motor 12 is started, it begins to run and output power. Since a first gear 13 is fixed to the output end of the reduction motor 12, the first gear 13 rotates along with the output shaft of the reduction motor 12. Because the first gear 13 is rotatably connected to the fixed block 11, and the second gear 14 is rotatably connected to the lower end inside the fixed block 11, and the first shaft 15 is fixed to the lower end of the second gear 14 and extends through the lower end of the fixed block 11 into the interior of the tank 10, with the first gear 13 and second gear 14 meshing together, when the first gear 13 rotates, the second gear 14 and the first shaft 15 rotate. Furthermore, because multiple first stirring rods 16 are fixed outside the first shaft 15 and inside the tank 10, the rotation of the first shaft 15 drives the first stirring rods 16 to rotate, and the rotation of the first stirring rods 16 can stimulate the internal components of the tank 10. The material is stirred, and because a second rotating shaft 17 is fitted inside the first rotating shaft 15, the second rotating shaft 17 passes through the first rotating shaft 15 and is rotatably connected to it. A third gear 18 is fixed on the outside of the second rotating shaft 17 and inside the fixed block 11. The third gear 18 is located above the first gear 13 and meshes with it. Therefore, when the first gear 13 rotates, the third gear 18 can rotate. Moreover, the rotation directions of the third gear 18 and the second gear 14 are different. The rotation of the third gear 18 drives the second rotating shaft 17 to rotate. Multiple second stirring rods 19 are fixed on the lower end of the outside of the second rotating shaft 17, so that the material is more fully mixed in the tank 10 and the stirring efficiency is improved. It should be noted that in the initial state, the first gear 13 and the second gear 14, as well as the third gear 18 and the second gear 14, are all meshed. The lower end of the tank 10 is provided with a discharge port, and a valve is provided on the outside of the discharge port.

[0028] In a preferred embodiment, please refer to Figure 2 A sealing ring is provided between the tank body 10 and the first rotating shaft 15, and the sealing ring is made of rubber.

[0029] In this embodiment, the rubber sealing ring has good elasticity and flexibility, which can fit tightly against the surfaces of the tank 10 and the first rotating shaft 15, filling the tiny gaps between them. This effectively prevents the material inside the tank 10 from leaking to the outside, ensuring that the mixing process is carried out in a closed environment, avoiding material loss and pollution to the surrounding environment. In addition, it can prevent external dust, impurities, etc. from entering the interior of the tank 10, maintaining the purity of the material inside the tank 10, and preventing impurities from mixing in and affecting the quality and performance of the material.

[0030] Secondly, please refer to it again. Figure 2 and Figure 4 Hydraulic rods 20 are fixed at the upper end of the tank body 10 and on both sides of the fixed block 11. The upper ends of the two hydraulic rods 20 are fixed with fixed plates 21. The lower end of the fixed plate 21 is rotatably connected to the second rotating shaft 17.

[0031] In this embodiment, because the upper end of the second rotating shaft 17 is rotatably connected to the lower end inside the fixed plate 21, and hydraulic rods 20 are fixed on both sides of the lower end of the fixed plate 21, when the hydraulic rods 20 are activated, the output ends of the two hydraulic rods 20 move upward, simultaneously driving the fixed plate 21 to move upward. The upward movement of the fixed plate 21 drives the second rotating shaft 17 to move. When the second rotating shaft 17 moves upward, it drives the third gear 18 to move upward. When the third gear 18 moves upward, it is no longer meshing with the first gear 13. At this time, the second rotating shaft 17 and the multiple second stirring rods 19 are no longer rotating, allowing the operator to flexibly switch the stirring mode according to the material stirring progress and process requirements, thereby improving the stirring efficiency.

[0032] Secondly, please refer to the following as well. Figure 3 and Figure 4 Dustproof plates 22 are fixed on both sides of the fixing block 11.

[0033] In this embodiment, the dustproof plate 22 can effectively block dust, debris and other impurities in the surrounding environment, making it difficult for them to enter the interior of the fixing block 11. This prevents these impurities from adhering to the transmission components of the first gear 13, the second gear 14 and the third gear 18, reducing component damage caused by impurity wear and extending the service life of the components.

[0034] To further understand and explain, Figure 5 For example, a feed pipe 25 is fixed at the upper end of the tank body 10 and on one side of the fixed block 11. A hopper 26 is fixed at the upper end of the feed pipe 25. A stirring motor 27 is fixed at the upper end of the hopper 26. A spiral blade 28 is fixed at the output end of the stirring motor 27, and the lower end of the spiral blade 28 passes through the feed pipe 25.

[0035] In this embodiment, the stirring motor 27 is started, and its output end drives the spiral blade 28 to rotate. The spiral blade 28 rotates in the hopper 26 and the feed pipe 25. In the hopper 26, the rotating spiral blade 28 performs preliminary stirring on the material, breaking up any lumps and making the material initially mixed evenly before entering the tank 10. On the other hand, the spiral structure of the spiral blade 28 generates axial thrust, pushing the material downward along the feed pipe 25 to realize the conveying of the material to the tank 10.

[0036] In a preferred embodiment, please refer to Figure 5 A stirring wheel 29 is fixed at the lower end of the feed pipe 25.

[0037] In this embodiment, when the material enters the tank 10 from the feed pipe 25 through the stirring wheel 29, the rotation of the stirring wheel 29 can perform secondary stirring on the material.

[0038] The working principle of this utility is as follows:

[0039] The stirring motor 27 on the hopper 26 is started, and its output end drives the spiral blades 28 to rotate, initially stirring and breaking up clumps in the material inside the hopper 26. At the same time, the spiral structure generates axial thrust to push the material down the feed pipe 25 to the tank 10. The stirring wheel 29 at the lower end of the feed pipe 25 performs secondary stirring on the material passing through. The reduction motor 12 is started, and its output shaft drives the first gear 13 to rotate. Since the first gear 13 meshes with the second gear 14, and the lower end of the second gear 14 is fixed with the first rotating shaft 15, the first rotating shaft 15 passes through the tank 10 and is fixed with the first stirring rod 16. Therefore, when the first gear 13 rotates, it drives the second gear 14 and the first shaft 15 to rotate, thereby causing the first stirring rod 16 to stir the material in the tank 10. At the same time, a third gear 18 that meshes with the first gear 13 is fixed on the outside of the second shaft 17 sleeved inside the first shaft 15. The rotation of the first gear 13 drives the third gear 18 to rotate, and the third gear 18 rotates in a different direction than the second gear 14. The rotation of the third gear 18 drives the second shaft 17 to rotate, and the second stirring rod 19 fixed at the lower end of the second shaft 17 further stirs the material, making the material mix more thoroughly and improving the stirring efficiency.

[0040] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
