[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0024] As Figures 1 to 4As shown in the figure, a stirring device for plastic product materials, the device includes a tank body 1, a support frame 2, a first stirring mechanism 3 and a second stirring mechanism 4. The tank body 1 is fixedly installed on the support frame 2 to ensure the stability and safety during the stirring process. There is a cavity inside the tank body 1 for accommodating the first stirring mechanism 3 and the second stirring mechanism 4. The top of the tank body 1 is provided with a feeding port 11, allowing users to easily add materials into the tank body 1. The bottom of the tank body 1 is provided with a discharging port 12 for discharging the stirred materials from the tank body 1.

[0025] Specifically, the first stirring mechanism 3 includes a stirring cylinder 31, first blades 32 and a first driving component 33. The stirring cylinder 31 is rotatably installed in the cavity. There is a stirring chamber inside the stirring cylinder 31. Both sides of the stirring chamber are open, and the stirring chamber is connected to the feeding port 11 and the discharging port 12. The stirring chamber is used to accommodate the plastic product materials to be stirred. The first blades 32 are arranged in a spiral shape on the inner wall of the stirring chamber. When the stirring cylinder 31 rotates, the spiral blades will push the materials to be mixed and stirred in the stirring chamber. The first driving component 33 is used to drive the rotation of the stirring cylinder 31 in the cavity, providing power for the first stirring mechanism 3.

[0026] Furthermore, the second stirring mechanism 4 includes a stirring shaft 41, second blades 42 and a second driving component 43. The stirring shaft 41 is rotatably installed in the stirring chamber and penetrates through the stirring cylinder 31, that is, the stirring shaft 41 is located inside the stirring cylinder 31. The second blades 42 are arranged in a spiral shape on the stirring shaft 41. The second driving component 43 is used to drive the rotation of the stirring shaft 41 in the stirring chamber, providing power for the second stirring mechanism 4.

[0027] When the stirring device starts to work, the user adds plastic product materials into the tank body 1 through the feeding port 11. The first driving component 33 is started to drive the stirring cylinder 31 to rotate in the tank body 1, and the first blades 32 push the materials to be preliminarily mixed in the stirring chamber. At the same time, the second driving component 43 is started to drive the stirring shaft 41 to rotate in the stirring chamber, and the second blades 42 further mix and stir the materials. Through the rotation of the first blades 32 and the second blades 42 in the stirring chamber, a complex flow pattern is formed in the stirring chamber, which helps to reduce the stirring dead corners and improve the uniformity and efficiency of stirring. After stirring is completed, the user can discharge the stirred materials from the tank body 1 through the discharging port 12.

[0028] Reference Figure 1 、 Figure 2 and Figure 3As shown, in some specific embodiments, in order to improve the stirring effect, the tank body 1 is a horizontal cylindrical tank body 1. The horizontal cylindrical shape is conducive to the uniform distribution and flow of materials in the tank body 1. Especially during the stirring process, it can reduce the accumulation of materials at the bottom of the tank body 1, improve the stirring efficiency. The stirring cylinder 31 is rotatably installed horizontally in the cavity, which enables the stirring cylinder 31 to stir the materials more evenly during rotation, reducing the dead corners of stirring. Similarly, the stirring shaft 41 is rotatably installed horizontally in the stirring cavity, rotating in the opposite direction to the stirring cylinder 31, which can further increase the uniformity and efficiency of stirring.

[0029] Reference Figure 4 As shown, in some specific embodiments, in order to further improve the stirring effect, the spiral direction of the first blade 32 is opposite to that of the second blade 42. This can ensure that during the stirring process, the two stirring mechanisms can form a complementary stirring effect in the stirring cavity, thereby further improving the stirring uniformity and efficiency. When the stirring cylinder 31 and the stirring shaft 41 rotate simultaneously, the opposite spiral directions of the first blade 32 and the second blade 42 will generate different flow patterns in the stirring cavity. This complex flow pattern helps to fully stir and mix the materials from all corners of the stirring cavity.

[0030] Reference Figure 2 and Figure 4 As shown, in some specific embodiments, in order to achieve the rotation of the stirring cylinder 31 driven by the first driving assembly 33 in the cavity, the first driving assembly 33 includes a transmission shaft 34, a first belt 35 and a first motor 36. The transmission shaft 34 is rotatably installed on the support frame 2 to ensure the stable rotation of the transmission shaft 34. A first gear 37 is provided on the outer side of the stirring cylinder 31. This gear is coaxially and fixedly connected to the stirring cylinder 31 and rotates with the rotation of the stirring cylinder 31. A second gear 38 that cooperates with the first gear 37 is provided on the transmission shaft 34. When the transmission shaft 34 rotates, the second gear 38 meshes with the first gear 37, thereby driving the stirring cylinder 31 to rotate. The first motor 36 is installed on the support frame 2 through a motor base, providing power for the rotation of the stirring cylinder 31. The first belt 35 is wound around the output ends of the transmission shaft 34 and the first motor 36. Through the transmission of the belt, the rotational movement of the first motor 36 is transmitted to the transmission shaft 34, and then the stirring cylinder 31 is driven to rotate.

[0031] Reference Figure 3 and Figure 4As shown, in some specific embodiments, in order to achieve the rotation of the stirring shaft 41 in the stirring chamber by the second driving assembly 43, the second driving assembly 43 includes a second belt 44 and a second motor 45. The second motor 45 is fixedly installed on the support frame 2 through a motor base to ensure a stable power source for the stirring shaft 41. The second belt 44 is wound around the output ends of the stirring shaft 41 and the second motor 45. When the second motor 45 starts to work, the rotational movement of its output end is transmitted to the stirring shaft 41 through the second belt 44, causing the stirring shaft 41 to rotate in the stirring chamber.

[0032] Reference Figure 4 As shown, in some specific embodiments, in order to optimize the operation of loading and unloading materials by users, a first material guiding groove 13 is fixedly installed at the feeding port 11. The first material guiding groove 13 can ensure that the materials enter the stirring chamber more smoothly and orderly, thereby improving efficiency. A first material separating plate 14 is movably installed in the first material guiding groove 13. The opening degree between the first material separating plate 14 and the first material guiding groove 13 can be adjusted to adjust and control the feeding speed and flow rate of the materials, ensuring that the materials can enter the stirring chamber evenly and stably, and further improving the uniformity of stirring. A second material guiding groove 15 is fixedly installed at the discharging port 12. The second material guiding groove 15 can ensure that the stirred materials are discharged more smoothly and orderly, avoiding scattering or blocking of the materials during the discharging process. A second material separating plate 16 is movably installed in the second material guiding groove 15. The opening degree between the second material separating plate 16 and the second material guiding groove 15 can be adjusted to control the discharging speed and flow rate of the materials, ensuring that the materials can be discharged evenly and stably, which is convenient for subsequent processing and packaging.

[0033] To facilitate the understanding of the embodiments of this solution by those skilled in the art, the working principle of the embodiments of this solution will be described below in combination with specific application scenarios:

[0034] In actual use, the user adds plastic product materials into the tank body 1 through the feeding port 11. The materials first enter the first material guiding groove 13, and the feeding speed and flow rate are controlled by adjusting the first baffle plate 14. The first driving assembly 33 is started, the first motor 36 drives the transmission shaft 34 to rotate through the first belt 35, and then meshes with the first gear 37 on the outer side of the mixing drum 31 through the second gear 38 to drive the mixing drum 31 to rotate horizontally in the tank body 1. The first blade 32 rotates with the mixing drum 31 to push the materials to be preliminarily mixed in the mixing cavity. At the same time, the second driving assembly 43 is started, and the second motor 45 drives the mixing shaft 41 to rotate in the mixing cavity through the second belt 44. The second blade 42 rotates with the mixing shaft 41 to further mix and stir the materials. Since the spiral directions of the first blade 32 and the second blade 42 are opposite, they form a complex flow pattern in the mixing cavity, which helps to reduce the dead angle of mixing and improve the uniformity and efficiency of mixing. After mixing is completed, the user discharges the mixed materials through the discharging port 12. The materials first enter the second material guiding groove 15, and the discharging speed and flow rate are controlled by adjusting the second baffle plate 16.
