[0002] Colored masterbatch is a new type of colorant specifically for polymer materials, also known as pigment preparation. It is mainly used in plastics. Colored masterbatch consists of three basic elements: pigment or dye, carrier, and additives. It is an aggregate made by uniformly loading an extraordinary amount of pigment into resin, and can be called a pigment concentrate, therefore its coloring power is higher than that of the pigment itself. During processing, a small amount of masterbatch is mixed with uncolored resin to achieve the designed pigment concentration in the resin or product.
[0003] A colored masterbatch mixing and stirring device, disclosed in Chinese Patent Publication No. CN220784490U, comprises a housing with a feed inlet.

It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.
[0024] like Figures 1 to 3 As shown, a colored masterbatch mixing and stirring device includes a mixing tank 2 with a stirring cover 1 installed on the top. The stirring cover 1 has a feed inlet, and the mixing tank 2 has a discharge outlet on one side. The stirring cover 1 is also provided with a stirring shaft 3, which passes through the stirring cover 1 and extends into the mixing tank 2. The stirring shaft 3 is provided with a plurality of stirring blades 4. The stirring cover 1 is provided with a rotating component for driving the stirring shaft 3 to rotate and a lifting component for changing the stirring space inside the mixing tank 2. The lifting component acts on the top of the stirring shaft 3, and the bottom of the stirring shaft 3 is provided with a reset component that cooperates with the lifting component.
[0025] In use, the material enters the mixing tank 2 through the feed inlet. The rotating component drives the mixing shaft 3 to rotate. The rotation of the mixing shaft 3 can drive the rotation of several mixing blades 4, so that the mixing blades 4 can stir the material. Through the cooperation of the reset component and the lifting component, the mixing space inside the mixing tank 2 can be enlarged or compressed, so that the material at the top and bottom can be uniformly stirred. After the stirring is completed, the material leaves the device through the discharge port.
[0026] The rotating assembly includes a rotating belt 5, which is mounted on the top of the stirring cover 1 via a rotating base plate 6. A driving wheel 7 and a driven wheel 8 are respectively wound around the two ends of the rotating belt 5. A drive motor 9 is mounted on the shaft of the driving wheel 7. The drive motor 9 is bolted to the rotating base plate 6 via a drive mounting plate 10. The driven wheel 8 is rotatably connected to the stirring shaft 3. A reinforcing rod 11 is mounted on the bottom of the rotating base plate 6. One end of the reinforcing rod 11 is fixed to the circumference of the stirring tank 2.
[0027] The rotating base plate 6, rotating belt 5, driving wheel 7 and driven wheel 8 are securely mounted on the mixing cover 1. The drive motor 9 serves as the power source, driving the driving wheel 7 to rotate. The rotation of the driving wheel 7 can drive the rotating belt 5 and driven wheel 8 to rotate, and the mixing shaft 3 rotates accordingly. The mixing blades 4 on the mixing shaft 3 uniformly mix the material. The rotating base plate 6 is supported by the reinforcing rod 11, so that the rotating base plate 6 and the components on the rotating base plate 6 will not shake or shift during operation.
[0028] The lifting assembly includes a lifting cylinder 12, which is located on the top of the stirring cover 1. A lifting connecting plate 13 is provided on the piston rod of the lifting cylinder 12, and the bottom of the lifting connecting plate 13 abuts against the top of the stirring shaft 3. The reset assembly includes a reset plate 14 that abuts against the bottom of the stirring shaft 3. Several reset springs 15 are provided on the bottom of the reset plate 14, and one end of the reset springs 15 is fixed to the bottom of the stirring tank 2.
[0029] Since the top and bottom of the stirring shaft 3 abut against the lifting connecting plate 13 and the reset plate 14 respectively, when there is a lot of material to be stirred, the lifting cylinder 12 retracts. The retraction of the lifting cylinder 12 drives the lifting connecting plate 13 to descend. The descent of the lifting connecting plate 13 drives the stirring shaft 3 to descend as a whole. The bottom of the stirring shaft 3 compresses the reset spring 15, expanding the space for stirring materials in the mixing tank 2, which can accommodate more materials. The stirring blades 4 stir the materials. When there is a little material to be stirred, the lifting cylinder 12 rises, the reset spring 15 rebounds, and the reset plate 14 exerts a force on the rotating shaft, so that the top of the rotating shaft continuously abuts against the lifting connecting plate 13, reducing the space for stirring materials in the mixing tank 2 and improving efficiency. When the lifting cylinder 12 rises, the reset plate 14 and the reset spring 15 can effectively push the stirring shaft 3 to reset.
[0030] A feed hopper 16 is provided at the feed inlet; the feed hopper 16 allows the material to enter the mixing tank 2 evenly, preventing the material from overflowing.
[0031] A discharge pipe 17 is provided at the discharge port, and a shut-off valve 18 is provided on the discharge pipe 17. The material that has been mixed can be discharged from the discharge pipe 17, and the shut-off valve 18 prevents the material that has not been mixed from being discharged from the mixing tank 2, so as not to cause the mixing of unprocessed and processed materials.
[0032] Working principle: Material enters the mixing tank 2 through the feed hopper 16. The shut-off valve 18 is closed, preventing unprocessed material from flowing out of the discharge pipe 17. When there is a large amount of material to be mixed, the lifting cylinder 12 retracts, causing the lifting connecting plate 13 to descend. The descent of the lifting connecting plate 13 causes the entire mixing shaft 3 to descend. The bottom of the mixing shaft 3 compresses the return spring 15, expanding the mixing space in the mixing tank 2 to accommodate more material. When there is a small amount of material to be mixed, the piston rod of the lifting cylinder 12 retracts upward, causing the lifting connecting plate 13 to descend. As plate 13 rises, stirring shaft 3 moves upward under the restoring force of return spring 15 until the top of stirring shaft 3 is in contact with lifting connecting plate 13. After adjusting the stirring space in stirring tank 2 according to the amount of material, drive motor 9, as the power source, drives drive wheel 7 to rotate. The rotation of drive wheel 7 can drive rotating belt 5 and driven wheel 8 to rotate, and stirring shaft 3 rotates accordingly. Stirring blades 4 on stirring shaft 3 stir the material evenly, achieving uniform stirring of materials at the top and bottom. After stirring is completed, shut-off valve 18 opens, and material is discharged from discharge pipe 17.
