On the contrary, when the outlet is closed, at this time, the discharge holes at the first partition plate and the second partition plate overlap. The materials on the first partition plate can be stirred and mixed through the baffle. When the stirring is uniform, the scraper pushes the materials, and the uniformly stirred materials fall into the stirring cylinder from the discharge holes at the first partition plate and the second partition plate, avoiding the situation that the materials enter the stirring cylinder without being uniformly mixed and affecting the quality of the finished product.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying 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 of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1-6 , an embodiment provided by the present utility model: A plastic multi-stage material mixer for uniform mixing, including a first mixing cylinder 1, a second mixing cylinder 2 is fixedly connected to the top of the first mixing cylinder 1, a fixed box 3 is installed on the outside of the second mixing cylinder 2, a stirring mechanism 4 is arranged on the top of the second mixing cylinder 2, and a batching mechanism 5 is arranged inside the second mixing cylinder 2,

[0027] The batching mechanism 5 includes a feed pipe 51, a second motor 52, a second connecting rod 53, a first driving gear 54, a first driven gear 55, a connecting plate 56 and a discharge port 57. Two groups of feed pipes 51 are installed at the top of the second mixing cylinder 2. A second motor 52 is installed in the fixed box 3. A second connecting rod 53 is provided at the end of the second motor 52. A first driving gear 54 is provided on the outer side of the second connecting rod 53. A first driven gear 55 is provided inside the second mixing cylinder 2. A connecting plate 56 is provided inside the first driven gear 55. A discharge port 57 adapted to the feed pipe 51 is formed inside the connecting plate 56. The first driven gear 55 meshes with the first driving gear 54;

[0028] Through the settings of the batching mechanism 5 and the synchronization mechanism 8, this device solves the problems that different materials cannot be proportioned according to a certain ratio, resulting in uneven mixing; the inner ends of the materials agglomerate and cannot be fully stirred, dispersed and mixed, affecting the quality of subsequent finished products.

[0029] Furthermore, the stirring mechanism 4 includes a first motor 41, a first connecting rod 42, stirring rods 43 and stirring wheels 44. The first motor 41 is fixedly installed at the center position of the top of the second mixing cylinder 2. The lower end of the first motor 41 is fixedly connected to the first connecting rod 42. The first connecting rod 42 is located at the center position inside the second mixing cylinder 2 and the first mixing cylinder 1. Stirring rods 43 are fixedly connected to the outer side of the first connecting rod 42. Stirring wheels 44 are rotatably connected to the outer surface of the stirring rods 43. As Figure 2 shown, this structure is used to drive the first connecting rod 42 and the stirring rods 43 to rotate through the first motor 41 to mix the materials inside the first mixing cylinder 1. At the same time, the stirring wheels 44 are in contact with the materials and rotate to improve the mixing effect.

[0030] Furthermore, a first partition plate 6 is fixedly connected between the first mixing cylinder 1 and the second mixing cylinder 2. A baffle 7 is fixedly connected to the part of the outer side of the first connecting rod 42 located inside the second mixing cylinder 2. An anti-blocking component 9 is arranged inside the baffle 7. As Figure 2 shown, this structure is used to separate the first mixing cylinder 1 and the second mixing cylinder 2 through the first partition plate 6 and the baffle 7, and to preliminarily stir and mix the materials at the inner end of the second mixing cylinder 2, so as to break up the materials and make the materials fully contact and mix, achieving the effect of uniform mixing.

[0031] Further, a synchronization mechanism 8 is provided at the bottom of the second mixing cylinder 2. The synchronization mechanism 8 includes a third connecting rod 81, a second synchronous pulley 82, a synchronous belt 83, a second driving gear 84, a second driven gear 85, a second partition plate 86, and a discharge hole 87. A third connecting rod 81 is rotatably connected in the fixed box 3. A second synchronous pulley 82 is fixedly connected to the outer surface of the third connecting rod 81. A first synchronous pulley 58 is fixedly connected to the outside of the second connecting rod 53. A synchronous belt 83 is movably connected to the outside of the first synchronous pulley 58 and the second synchronous pulley 82. A second driving gear 84 is fixedly connected to the end of the third connecting rod 81. A second driven gear 85 is movably connected inside the second mixing cylinder 2. A second partition plate 86 is fixedly connected to the inside of the second driven gear 85. Discharge holes 87 are equidistantly formed on the surface of the second partition plate 86. As Figure 5 shown, this structure is used to drive the second connecting rod 53 to rotate through the second motor 52. Under the action of the first synchronous pulley 58 and the synchronous belt 83, the third connecting rod 81 and the second driving gear 84 are driven to rotate. Through the meshing of the second driving gear 84 and the second driven gear 85, the second driven gear 85 drives the second partition plate 86 to rotate, overlapping the discharge holes 87 at the second partition plate 86 with the holes at the first partition plate 6, so that the material falls into the first mixing cylinder 1.

[0032] Further, a part of the outer surface of the feed pipe 51 is made of a transparent material, and scale lines are provided on both sides. A first driven gear 55 is fixedly connected to the outside of the connecting plate 56. The first driven gear 55 is located inside the second mixing cylinder 2 and is movably connected to the second mixing cylinder 2. A first driving gear 54 is provided below the first driven gear 55. The right end of the first driving gear 54 is fixedly connected to a second connecting rod 53. The right end of the second connecting rod 53 is connected to the second motor 52. As Figure 4 shown, this structure is used to pour the material into the feed pipe 51 to mix the material, avoiding inconsistent proportions from affecting the mixing effect. After the mixing is completed, the second motor 52 is started. The second motor 52 drives the second connecting rod 53 and the first driving gear 54 to rotate. Under the meshing action of the first driving gear 54 and the first driven gear 55, the first driven gear 55 drives the connecting plate 56 to rotate, overlapping the discharge port 57 at the connecting plate 56 with the feed pipe 51, so that the mixed material falls into the second mixing cylinder 2.

[0033] Further, the anti-blocking component 9 includes a movable rod 91, a spring 92, and a scraper 93. A movable rod 91 is movably connected inside the baffle 7. A spring 92 is provided inside the movable rod 91. Both ends of the spring 92 abut against the movable rod 91 and the inner wall of the baffle 7 respectively. A scraper 93 is fixedly connected to the bottom of the movable rod 91. The cross-section of the edge of the scraper 93 is triangular. As Figure 6As shown in the figure, when the first motor 41 drives the first connecting rod 42 to rotate, the baffle 7 is driven to rotate to mix the materials in the second mixing cylinder 2. While the baffle 7 is rotating, under the elastic action of the spring 92, the movable rod 91 drives the scraper 93 to fit on the surface of the first partition plate 6, and the materials on the surface of the first partition plate 6 are scraped off by the scraper 93.

[0034] Furthermore, limit rings 10 are fixedly connected to the outer sides of the first driven gear 55 and the second driven gear 85, and sliding grooves adapted to the limit rings 10 are formed in the inner wall of the second mixing cylinder 2. As Figure 3 shown in the figure, this structure is used to enable the first driven gear 55 and the second driven gear 85 to rotate stably in the second mixing cylinder 2 through the arrangement of the limit rings 10, thereby improving the stability of the device.

[0035] Working principle: When in use, as Figure 4 shown in the figure, first pour the materials into the feed pipe 51, and adjust the appropriate ratio by observing the scale line on the surface of the feed pipe 51. At this time, the bottom of the feed pipe 51 is blocked by the connecting plate 56. After the preparation is completed, close the inlet of the feed pipe 51, drive the second motor 52, and drive the second connecting rod 53 and the first driving gear 54 to rotate through the second motor 52. Under the meshing action of the first driving gear 54 and the first driven gear 55, the first driven gear 55 drives the connecting plate 56 to rotate, overlap the discharge port 57 at the connecting plate 56 with the feed pipe 51, and make the prepared materials fall into the second mixing cylinder 2. As Figure 2 shown in the figure, start the first motor 41 to mix the materials in the first mixing cylinder 1. At the same time, drive the baffle 7 to preliminarily stir and mix the materials in the second mixing cylinder 2, disperse the materials, and make the materials fully contact and mix to achieve the effect of uniform mixing. As Figure 5 shown in the figure, start the second motor 52 again. When the second motor 52 drives the second connecting rod 53 to rotate, the bottom of the feed pipe 51 is closed. At the same time, under the action of the first synchronous pulley 58 and the synchronous belt 83, drive the third connecting rod 81 and the second driving gear 84 to rotate. Through the meshing of the second driving gear 84 and the second driven gear 85, the second driven gear 85 drives the second partition plate 86 to rotate, overlap the discharge hole 87 at the second partition plate 86 with the hole at the first partition plate 6, and make the materials fall into the first mixing cylinder 1. Drive the first connecting rod 42 and the stirring rod 43 to rotate through the first motor 41. At the same time, make the stirring wheel 44 contact and rotate with the materials to improve the mixing effect. The above is all the working principle of the present utility model.
