[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] This utility model provides, for example Figures 1-4 The PVC plastisol production and storage device shown includes an outer cylinder 1, a guide plate 15, a stirring mechanism, and a rotary drive mechanism. An inner cylinder 5 is fixedly connected inside the outer cylinder 1, and the inner cylinder 5 and the outer cylinder 1 cooperate to form a heat insulation layer. A second rotating shaft 13 is rotatably connected to the inner cavity of the inner cylinder 5. The guide plate 15 is fixedly sleeved on the outer wall of the second rotating shaft 13. The stirring mechanism causes the PVC plastisol in the inner cylinder 5 to form a vortex. The stirring mechanism is located at the upper part of the inner cavity of the inner cylinder 5, which makes the rotation of the stirring mechanism more stable, prevents the stirring mechanism from overloading due to the high viscosity of the bottom of the PVC plastisol, and reduces energy consumption. The end of the second rotating shaft 13 opposite to the inner cylinder 5 is fixed. A connecting cylinder 14 is fixedly connected, and a stirring mechanism is set inside the inner cylinder 5. The stirring mechanism is used to stir the PVC plastisol. A rotary drive mechanism is set inside the inner cylinder 5 and is used to drive the guide plate 15 to rotate. Specifically, the outer cylinder 1 and the inner cylinder 5 form a double layer of protection to improve the heat preservation effect. During the storage of PVC plastisol, the stirring mechanism is used to stir the PVC plastisol. With the help of the guide plate 15, turbulence is formed at the bottom of the inner cylinder 5, breaking the static storage state and eliminating the effect of stratification. At the same time, the rotary drive mechanism is used to adjust the angle of the guide plate 15 to adapt to different viscosities of PVC plastisol.

[0024] On one hand, the top of the outer cylinder 1 is fixedly connected to the feed cylinder 3, the bottom of the outer cylinder 1 is rotatably connected to the discharge cylinder 10, and the bottom of the outer cylinder 1 is fixedly connected to the support rod 4. The feed cylinder 3 and the discharge cylinder 10 are used to complete the addition and discharge of PVC plastisol.

[0025] On the other hand, the stirring mechanism includes a stirring blade 7, and a first rotating shaft 6 is rotatably connected to the inner cavity of the outer cylinder 1. The stirring blade 7 is fixedly sleeved on the outer wall of the first rotating shaft 6. The first rotating shaft 6 can provide support for the stirring blade 7, so that the stirring blade 7 can work stably. A driving component 2 is fixedly connected to the top of the outer cylinder 1. The driving component 2 is a motor. The driving component 2 is used to drive the first rotating shaft 6 to rotate. The periodic rotation of the stirring blade 7 is used to prevent the PVC plastisol from delaminating.

[0026] Preferably, the rotary drive mechanism includes a second bevel gear 12, which is annular. A rotating plate 8 is rotatably connected to the inner cavity of the outer cylinder 1. The rotating plate 8 is rotatably connected to the bottom of the inner cylinder 5. The second bevel gear 12 is rotatably connected to the top of the rotating plate 8. A second rotating shaft 13 extends to the outside of the inner cylinder 5. A first bevel gear 11 is fixedly connected to one end of the second rotating shaft 13 away from the connecting cylinder 14. The first bevel gear 11 meshes with the second bevel gear 12. Multiple guide plates 15 are arranged in a circumferential array. The multiple guide plates 15 form a flow channel to control the flow direction of PVC plastisol, creating turbulence, increasing shear force, and preventing bottom deposition. The discharge cylinder 10 is fixedly connected to the bottom of the inner cylinder 5. The rotating plate 8 drives the second bevel gear 12 to rotate. The second bevel gear 12 drives the multiple second rotating shafts 13 to rotate through the multiple first bevel gears 11. The second rotating shafts 13 drive the guide plates 15 to rotate, adjusting the angle of the guide plates 15 to increase their applicability.

[0027] Additionally, a limiting groove 16 is provided at the bottom of the outer cylinder 1. Multiple limiting grooves 16 are arranged in a circumferential array. A circular plate 18 is fixedly sleeved on the outer wall of the discharge cylinder 10. An elastic element 19 is slidably arranged on the outer wall of the circular plate 18. The elastic element 19 includes a circular rod and a spring. A limiting block 17 is fixedly connected to one end of the elastic element 19 near the outer cylinder 1. The limiting block 17 engages with one of the limiting grooves 16, thus fixing and limiting the continuation plate 18. A pull rod 9 is fixedly arranged at the end of the elastic element 19 away from the limiting block 17. In actual use: when the worker pulls the pull rod 9, the pull rod 9, through the stretching elastic element 19, causes the limiting block 17 to disengage from the limiting groove 16. Then, the pull rod 9 is rotated, causing the rotating plate 8 to rotate through the circular plate 18 and the discharge cylinder 10. The rotating plate 8 causes the guide plate 15 to rotate. After adjusting the guide plate 15, the pull rod 9 is released, and the elastic element 19 causes the limiting block 17 to reset.

[0028] During operation: the drive unit 2 is periodically activated to drive the first rotating shaft 6 to rotate. The periodic rotation of the stirring blade 7 prevents the PVC plastisol from separating. The worker pulls the lever 9, which, through the stretching elastic element 19, causes the limiting block 17 to disengage from the limiting groove 16. Then, the lever 9 is rotated, which, through the circular plate 18 and the discharge cylinder 10, causes the rotating plate 8 to rotate. The rotating plate 8 then drives the second bevel gear 12 to rotate. The second bevel gear 12, through multiple first bevel gears 11, drives multiple second rotating shafts 13 to rotate. The second rotating shafts 13 drive the guide plate 15 to rotate. The angle of the guide plate 15 is adjusted to increase its applicability. After the guide plate 15 is adjusted, the lever 9 is released, and the elastic element 19 causes the limiting block 17 to reset.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
