[0002] In today's booming plastics processing industry, the raw material mixing and conveying process, as the fundamental upstream link of the entire production chain, plays a crucial role in the quality, production efficiency, and cost control of subsequent plastic products. Plastics processing is a general term for various processes that transform synthetic resins or plastics into plastic products. It is a major production sector within the plastics industry, generally including steps such as plastic batching, molding, machining, joining, finishing, and assembly. During the batching process, raw materials often need to be stirred, mixed, and conveyed. Traditional mixing and conveying devices often suffer from insufficient mixing and easy blockages, making it difficult to meet the ever-increasing production demands and the requirements for high-quality products. Some simple mixing devices cannot fully integrate plastic raw materials with different properties. Moreover, in the conveying stage, due to poor material flowability or unreasonable conveying structures, material accumulation and pipe blockages often occur, not only reducing production efficiency but also increasing equipment maintenance costs. Utility Model Content

[0014] 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.

[0015] Example: Figure 1-3As shown, this utility model provides a plastic processing raw material mixing and conveying device, including a first support 1. A mixing tank 11 is fixedly installed inside the first support 1. Multiple fixing members 10 are fixedly installed on the outer surface of the mixing tank 11, and the fixing members 10 are arranged in a ring array. The lower surface of the fixing members 10 is fixedly connected to the upper surface of the first support 1. The ring array of fixing members 10 provides support and fixation for the mixing tank 11, ensuring the stability of the mixing tank 11 during the mixing process. A frame 13 is fixedly installed on the upper surface of the mixing tank 11. A feed inlet 12 is opened on the upper surface of the mixing tank 11 near the frame 13, which facilitates the operator to feed the material into the mixing tank 11 through the feed inlet 12. A stirring device 2 is fixedly inserted inside the frame 13. A conveying device 3 is fixedly installed at the lower end of the mixing tank 11. The mixing device 2 includes a mixing shaft 21 located inside the mixing tank 11. Multiple spiral mixing blades 22 are fixedly fitted onto the outer surface of the mixing shaft 21. A worm gear mixing blade 23 is fixedly installed at the bottom end of the mixing shaft 21. A first motor 24 is fixedly connected to the upper surface of the frame 13. A connecting plate 25 is fixedly connected to the upper inner wall of the frame 13. A sleeve 26 is fixedly connected to the lower surface of the connecting plate 25. An inclined annular track 28 is formed on the inner surface of the sleeve 26. A connecting pin is fixedly connected to the outer surface of the cylindrical assembly 29, and the outer surface of the connecting pin slides against the outer surface of the inclined annular track 28. A rotating square rod... 27 drives the cylindrical component 29 to rotate. The rotating cylindrical component 29 is slidably connected to the inclined annular track 28 through the connecting pin. While the cylindrical component 29 rotates, it moves up and down along the trajectory of the inclined annular track 28 on the outer surface of the square rod 27, thus achieving the purpose of rotating and moving up and down at the same time. The output end of the first motor 24 passes through the connecting plate 25 and is fixedly connected to the square rod 27. The cylindrical component 29 is slidably sleeved on the outer surface of the square rod 27. The outer surface of the cylindrical component 29 is slidably connected to the inner wall of the sleeve 26. The lower end of the cylindrical component 29 is fixedly connected to the stirring shaft 21. The conveying device 3 includes a second support 31, on the upper surface of which a material trough 33 is fixedly installed. The mixing tank 11 is conical, and its lower end is connected to the material trough 33. The conical shape of the mixing tank 11 facilitates the material to have a reasonable flow path during the mixing process, making it easier for the material to be discharged. The mixed material flows into the material trough 33 through the lower end of the mixing tank 11. The material trough 33 is equipped with a rotating conveying paddle 34, which is horizontally spiral. When the conveying paddle 34 rotates under the drive of the second motor 32, the spiral blades can gradually push the mixed plastic raw material in the material trough 33 forward. This structure can make the material evenly dispersed and pushed in the horizontal direction, avoiding local accumulation of material.A second pulley 35 is fixedly sleeved at one end of the conveying paddle 34. A second motor 32 is fixedly installed on one side of the second bracket 31. A first pulley 36 is fixedly sleeved at the output end of the second motor 32. A synchronous belt 37 is sleeved on the outer surface of the second pulley 35 and the outer surface of the first pulley 36. The size of the second pulley 35 is larger than that of the first pulley 36. The outer surfaces of both the first pulley 36 and the second pulley 35 are treated with anti-slip treatment. Because the outer surfaces of the second pulley 35 and the first pulley 36 are treated with anti-slip treatment, this can effectively prevent the synchronous belt 37 from slipping during transmission. A discharge pipe 38 is connected through one side of the material trough 33.

[0016] Working principle: When stirring is required, the material enters the mixing tank 11 through the feed inlet 12. The first motor 24 in the stirring device 2 is started. The output end of the first motor 24 drives the square rod 27 to rotate, thereby driving the cylindrical component 29 to rotate on the inner wall of the sleeve 26. The rotating cylindrical component 29 slides up and down on the outer surface of the square rod 27 along the movement trajectory of the inclined annular track 28 through the connecting pin, thereby driving the stirring shaft 21, the spiral stirring paddle 22, and the worm gear stirring paddle 23 at the bottom of the cylindrical component 29 to move up and down to a certain extent while stirring. The spiral stirring paddle 22 rotates together with the stirring shaft 21. Due to its own spiral structure, it will generate an upward pushing force on the plastic raw material at the bottom of the mixing tank 11 during the rotation process. The worm gear stirring paddle 23 also rotates under the drive of the stirring shaft 21. Its unique worm gear shape structure will apply a pushing force to the raw material in the mixing tank 11 from the side, thereby achieving full stirring of the material. When conveying is required, the conveying paddle 34 has a spiral structure. The second motor 32 is started, and the output end of the second motor 32 drives the conveying paddle 34 to rotate inside the material trough 33 through the transmission of the first pulley 36, the second pulley 35 and the synchronous belt 37. The mixed material that is received in the material trough 33 from the bottom outlet of the mixing tank 11 will move forward along the direction of the material trough 33 under the push of the spiral blades of the conveying paddle 34. The continuous rotation of the conveying paddle 34 can stably and continuously convey the mixed plastic raw material to the outlet pipe 38 for outflow, ensuring the smoothness of the material conveying link in the entire production process and preventing blockages and accumulation of materials during the conveying process.
