DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0032] Embodiment one:

[0033] In this embodiment, in order to improve the overall mixing effect, the filter plate 6 is used, which is used to reduce the problem of uneven mixing caused by material aggregation, such as Figures 1-4The technical solution shown includes a mixing cylinder 1, a feeding hopper 3 connected to the mixing cylinder 1 via a processing cylinder 2, a drive motor 4 mounted on the processing cylinder 2, and a first rotating shaft 5 connected to the output end of the drive motor 4. A filter plate 6 is installed inside the processing cylinder 2, and a rotating component 7 is mounted on the outside of the first rotating shaft 5, located above the filter plate 6. The first rotating shaft 5 extends through the interior of the mixing cylinder 1, and a mixing component 11 is mounted on its outside. A conveying pipe 9 is connected to the bottom of the filter plate 6 via a receiving component 8, extending through the interior of the mixing cylinder 1. A flexible hose 10 is installed on the conveying pipe 9. A discharge pipe 12 is installed at the bottom of the mixing cylinder 1. The EVA material to be mixed is introduced into the processing cylinder 2 through the feeding hopper 3. The filter plate 6 inside the processing cylinder 2 filters the material, and the filtered material is then transferred through the receiving component 8, reducing [the amount of material removed]. To address the issue of uneven mixing caused by material aggregation, the material is transported to the mixing cylinder 1 via the conveying pipe 9 and the hose 10. The drive motor 4 drives the first rotating shaft 5 to rotate, which in turn drives the rotating component 7 to rotate on the surface of the filter plate 6. The rotation of the rotating component 7 further breaks up any agglomerates, preventing material from accumulating and clogging the filter plate 6, thus ensuring the continuous and smooth operation of the filtration process. The first rotating shaft 5 rotates inside the mixing cylinder 1 via the mixing component 11, thus mixing the materials. Using the same power source to drive both the filtration and mixing processes reduces energy consumption and equipment costs, minimizes the increased costs associated with higher drive requirements for mixing, and lowers maintenance costs. The mixed material can be output through the discharge pipe 12, facilitating connection with subsequent processing steps and improving the coordination and stability of the overall production process.

[0034] Example 2:

[0035] In this embodiment, to reduce the overall driving cost, a mobile component is used. The purpose is to reduce the increased cost caused by setting up additional drivers. Specifically, as follows... Figures 2-6As shown, a half gear 13 is sleeved on the outer side of the first rotating shaft 5. A moving assembly is installed on the outer side of the half gear 13. The moving assembly includes a toothed block 14 meshing with the side end of the half gear 13. The toothed blocks 14 are symmetrically distributed inside the moving box 15. A moving block 16 is installed on the upper end of the moving box 15. The moving block 16 is sleeved on the outer side of the guide rod 17. The guide rod 17 is installed inside the auxiliary box 18. The auxiliary box 18 is installed at the top inside the mixing cylinder 1. An extrusion ball 19 is installed on the side end of the moving box 15. After the extrusion ball 19 moves, it contacts the conveying pipe 9. The side end of the conveying pipe 9 is connected to the inner wall of the mixing cylinder 1 through a lifting rod 20. A spring 21 is sleeved on the outer side of the lifting rod 20. When the first rotating shaft 5 rotates, the outer side of the first rotating shaft 5 drives the half gear 13 to rotate, so that the half gear 13 passes through the inside of the moving box 15. The toothed block 14 drives the moving box 15 to move. The mechanical structure design is simple and efficient, requiring no additional drive, which reduces the failure rate and maintenance cost of the equipment. At this time, the top of the moving box 15 moves on the guide rod 17 inside the auxiliary box 18 through the moving block 16, so that the extrusion ball 19 on the side of the moving box 15 extrudes the conveying pipe 9. The conveying pipe 9 moves with the cooperation of the hose 10, effectively preventing the material from being blocked in the conveying pipe 9. Since the side of the conveying pipe 9 is connected to the spring 21 through the lifting rod 20, it is convenient to shake the conveying pipe 9 by the cooperation of the lifting rod 20 and the spring 21. The shaking effect can further promote the flow of material in the conveying pipe 9, thereby improving the feeding efficiency and reducing the residence time of material in the conveying process, thus improving the overall production efficiency.

[0036] Example 3:

[0037] In this embodiment, to improve the overall stability of material discharge, a drive component is used. The purpose is to reduce the problem of unstable discharge caused by material gushing or clogging during discharge. Specifically, as follows... Figure 2 and Figure 7As shown, a dual-axis motor 22 is installed at the bottom of the mixing cylinder 1. A guide 23 is connected to the first output end of the dual-axis motor 22, and the guide 23 is installed inside the discharge pipe 12. A drive assembly is connected to the second output end of the dual-axis motor 22. The drive assembly includes a rotating rod 24 installed at the second output end of the dual-axis motor 22. A second bevel gear 26 is meshed with the end of the rotating rod 24 via a first bevel gear 25. A second rotating shaft 27 is installed inside the second bevel gear 26 and extends through the mixing cylinder 1. A threaded plate 28 is installed on the outside of the second rotating shaft 27. When the dual-axis motor 22 is turned on, the first output end of the dual-axis motor 22 drives the guide 23 to rotate inside the discharge pipe 12, making the discharge more stable. The rotation of the guide 23 can control the discharge feed. The guide design effectively prevents material from gushing or clogging during discharge, ensuring more stable discharge and facilitating control of the discharge flow rate and direction. This facilitates subsequent processing operations and improves the overall coordination of the production line. The second output end of the dual-shaft motor 22 drives the rotating rod 24 to rotate. The rotating rod 24 drives the second bevel gear 26 to rotate via the first bevel gear 25. The second bevel gear 26 then drives the threaded disc 28 to rotate inside the mixing cylinder 1 via the second rotating shaft 27, thoroughly stirring, turning, and mixing the material. The threaded disc 28 allows the material to exchange at different levels, resulting in more uniform mixing and improved mixing efficiency. Content not described in detail in this specification belongs to the prior art known to those skilled in the art.

[0038] Although the present invention 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
