Description

Technical Field

[0001] This utility model relates to the field of mixers, and more particularly to a self-cleaning rubber powder mixer with high efficiency. Background Technology

[0002] In the field of rubber product manufacturing, the uniform mixing of rubber powder is a key step in ensuring product quality. With the development of the rubber industry, the requirements for mixing quality are increasing. As a result, rubber powder mixers have emerged. Through specific mixing structures and process parameter designs, they achieve efficient and uniform mixing of rubber powder, improve production efficiency and product quality, and meet the needs of large-scale industrial production.

[0003] In existing technologies, common mixers have many limitations in their mixing structure and motion. The mixing shaft and rod of existing mixers typically only perform simple rotation or reciprocating motion, with a single motion trajectory, failing to create a complex and effective mixing flow field. This results in insufficient relative motion between rubber powders of different particle sizes and densities within the mixer, leading to incomplete mixing. For example, due to the limitations of the motion, denser rubber powders may sink rapidly under gravity, while less dense powders may float, further exacerbating the unevenness of the mixture. Furthermore, material in the mixer can adhere to the inner wall of the mixing tank, forming stains that contaminate subsequent materials. Excessive material adhesion to the inner wall of the mixing tank also affects mixing efficiency. Utility Model Content

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0024] Please see Figure 1 - Figure 4In one embodiment of this utility model: a high-efficiency self-cleaning rubber powder mixer includes a mixing tank body 1 and a first motor 21. A supporting mounting base 4 is fixedly connected to the bottom of the mixing tank body 1. A discharge outlet body 5 for discharging materials is fixedly connected to the mixing tank body 1. The first motor 21 is fixedly connected to the mounting base 4. A first transmission wheel 22 is fixedly connected to the output end of the first motor 21 and rotatably connected to the mounting base 4. A first rotating shaft 23 is rotatably connected to the mixing tank body 1. A second transmission wheel 24 is fixedly connected to one end of the first rotating shaft 23. A transmission belt 25 drives the second transmission wheel 24 and the first transmission wheel 22. A first fixed gear 26 is fixedly connected to the first rotating shaft 23. A fixed sleeve 27 is fixedly connected to the mounting base 4. A second fixed gear 28 is rotatably connected to the fixed sleeve 27 and meshes with the first fixed gear 26. A secondary rotating shaft 29 is slidably connected to the second fixed gear 28. A fixed base 210 is fixedly connected to the bottom of the rotating shaft 29. A rolling wheel 211 for supporting the fixed base 210 is rotatably connected to the fixed base 210. A fixed cam 212 is fixedly connected to the mounting base 4. A stirring rod body 213 for stirring materials is fixedly connected to the auxiliary rotating shaft 29. In use, after the material is poured into the mixing tank body 1, the first motor 21 drives the first transmission wheel 22 to rotate. When the first transmission wheel 22 rotates, it cooperates with the second transmission wheel 24 and the transmission belt 25 to drive the first rotating shaft 23 to rotate. When the first rotating shaft 23 rotates, it drives the first fixed gear 26 to rotate. When the first fixed gear 26 rotates, it cooperates with the second fixed gear 28 to drive the auxiliary rotating shaft 29 to rotate. When the auxiliary rotating shaft 29 rotates, it drives the fixed base 210 to rotate. When the fixed base 210 rotates, it cooperates with the rolling wheel 211 and the fixed cam 212 to drive the auxiliary rotating shaft 29 to move up and down, thereby driving the stirring rod body 213 to fully stir the material.

[0025] Please see Figure 1 - Figure 6In this embodiment, the fixed sleeve 27 has a limiting groove at the relative position of the second fixed gear 28. The second fixed gear 28 is rotatably connected inside the groove. The groove restricts the rotation of the second fixed gear 28, preventing it from disengaging from the fixed sleeve 27 during rotation and affecting its ability to drive the rotation of the auxiliary rotating shaft 29. The auxiliary rotating shaft 29 has a matching groove at the relative position of the second fixed gear 28. The auxiliary rotating shaft 29 is slidably connected to the second fixed gear 28 through the groove. The groove prevents the auxiliary rotating shaft 29 from disengaging from the second fixed gear 28 when sliding up and down, thus preventing the second fixed gear 28 from driving the rotation of the auxiliary rotating shaft 29. The mixing tank body 1 is located on the first rotating shaft. A groove is provided at the relative position of the first rotating shaft 23. The first rotating shaft 23 is rotatably connected inside the groove. The rotation of the first rotating shaft 23 is restricted by the groove to prevent the first rotating shaft 23 from tilting and affecting the engagement of its first fixed gear 26 and second fixed gear 28. A water tank 214 for storing cleaning fluid is fixedly connected to the mounting base 4. A water pump body 215 for drawing cleaning fluid is installed on the water tank 214. One end of the water pump body 215 is fixedly connected to the inside of the water tank 214. A fixed pipe 216 is fixedly connected inside the mixing tank body 1. A connecting hose 217 is fixedly connected between the fixed pipe 216 and the water pump body 215. The end of the first rotating shaft 23 away from the second transmission wheel 24 is fixedly connected to a connecting hose. A rack 218 is fixedly connected to a fixing buckle 219 on the mixing tank body 1. A drain outlet 220 for spraying cleaning fluid is rotatably connected to the fixing buckle 219. The drain outlet 220 is rotatably connected to a fixed pipe 216. A third fixed gear 221 is fixedly connected to the drain outlet 220 and meshes with the connecting rack 218. A fixing bracket 222 is fixedly connected to the connecting rack 218. A cleaning scraper 223 for cleaning the inner wall of the mixing tank body 1 is fixedly connected to the fixing bracket 222. When it is necessary to clean the inside of the mixing tank body 1, the connecting rack 218 rotates, driving the cleaning scraper 223 to clean the inside of the mixing tank body 1, while simultaneously driving the third fixed gear. The third fixed gear 221 rotates with the drain outlet 220 to increase the spray area of ​​the cleaning fluid and improve the overall cleaning efficiency. The fixing buckle 219 has a rotating groove at the relative position of the drain outlet 220. The drain outlet 220 is rotatably connected to the inside of the rotating groove. The rotating groove restricts the position of the drain outlet 220 to prevent it from tilting or disengaging when rotating, which would affect the cooperation between the third fixed gear 221 and the connecting rack 218. The fixing pipe 216 has a rotating groove at the relative position of the drain outlet 220. The drain outlet 220 is rotatably connected to the inside of the rotating groove. When the drain outlet 220 rotates with the third fixed gear 221, it disengages from the fixing pipe 216, which would affect the normal spraying of the cleaning fluid before cleaning work begins.

[0026] During operation, after the material is poured into the mixing tank body 1, the first motor 21 drives the first transmission wheel 22 to rotate. When the first transmission wheel 22 rotates, it engages with the second transmission wheel 24 and the transmission belt 25, causing the first rotating shaft 23 to rotate. The rotation of the first rotating shaft 23 drives the first fixed gear 26 to rotate. The rotation of the first fixed gear 26, in turn, engages with the second fixed gear 28, causing the auxiliary rotating shaft 29 to rotate. The rotation of the auxiliary rotating shaft 29 causes the fixed base 210 to rotate. The rotation of the fixed base 210, in turn, engages with the rolling wheel 211 and the fixed cam 212, causing the auxiliary rotating shaft 29 to reciprocate up and down, thereby driving the mixing rod. The body 213 thoroughly mixes the materials. When cleaning is required, the water pump body 215 operates, causing the cleaning liquid inside the water tank 214 to be transported to the drain outlet 220 through the connecting hose 217 and the fixed pipeline 216. As the cleaning liquid sprays out of the drain outlet 220, the first rotating shaft 23 rotates, driving the connecting rack 218 and the fixed bracket 222 to rotate. When the connecting rack 218 rotates, it cooperates with the third fixed gear 221, causing the drain outlet 220 to rotate on the fixed buckle 219, thereby increasing the spray area of ​​the cleaning liquid. When the fixed bracket 222 rotates, it drives the cleaning scraper 223 to rotate, thereby cleaning the inner wall of the mixing tank body 1.

[0027] Through the above steps, the secondary rotating shaft 29 drives the stirring rod body 213 to rotate and stir the material. At the same time, the rolling wheel 211 cooperates with the fixed cam 212 to drive the secondary rotating shaft 29 to move up and down reciprocally. This solves the common problem that the stirring rod is difficult to move relatively fully inside the mixer, resulting in the material not being fully mixed and affecting subsequent use.

[0028] The foregoing general description of the utility model and its specific embodiments should not be construed as limiting the technical solution of the utility model. Those skilled in the art, based on the disclosure of this application, can add, reduce, or combine the disclosed technical features in the foregoing general description and / or specific embodiments (including examples) without departing from the constituent elements of the utility model, to form other technical solutions within the protection scope of this application.
