Technical Field

[0001] The utility model relates to a mixer, in particular to a mixer for color masterbatch. Background Art

[0002] Masterbatch is a mixture of resin and a large amount of pigment (up to 50%) or dye with high color concentration. It is an aggregate made by uniformly loading an extraordinary amount of pigment or dye in the resin. During the processing, only a small amount of masterbatch is needed to mix with uncolored resin to achieve the colored resin or product with the designed pigment concentration.

[0003] The basic components of masterbatch include pigments or dyes, carriers, dispersants and other additives. In the production of masterbatch, multiple raw materials need to be stirred and mixed. The current stirring equipment generally only realizes the stirring and mixing function by driving a stirring blade driven by a motor. The stirring blade rotates in one direction during stirring, and the raw materials will rotate with the stirring blade, which makes it difficult to fully and comprehensively mix the raw materials, affecting work efficiency. Utility Model Content

[0004] In order to overcome the disadvantage that the raw materials will rotate along with the stirring blades when stirring, which makes it difficult to fully and comprehensively mix the raw materials and affects work efficiency, the technical problem of the utility model is to provide a masterbatch mixer that can realize bidirectional rotation stirring, fully and comprehensively mix the raw materials and improve work efficiency.

[0005] The technical implementation scheme of the utility model is: a masterbatch mixer, including a mixing barrel, a servo motor, a hopper, a stirring rod, a stirring frame, a fixed plate, an inner gear ring, a mounting plate, a first gear and a second gear. A servo motor is installed in the middle of the top of the mixing barrel, the top of the mixing barrel is connected to the hopper, the top of the mixing barrel is rotatably connected to the stirring rod, the top of the stirring rod is connected to the output shaft of the servo motor, the stirring frame is rotatably connected to the stirring rod, the outer end of the blade of the stirring frame is connected to the fixed plate, the fixed plate is in contact with the inner wall of the mixing barrel, the stirring frame passes through the bottom of the mixing barrel and is rotatably connected to the mixing barrel, the bottom of the stirring frame is connected to the inner gear ring, the bottom of the mixing barrel is connected to the mounting plate, the first gear and the second gear are rotatably connected on the mounting plate, the first gear is meshed with the inner gear ring, the second gear is meshed with the first gear and is connected to the mixing barrel.

[0006] Further description, it also includes a scraper, the stirring frame is connected with the scraper, and the scraper is in contact with the bottom of the stirring barrel.

[0007] Further description, it also includes a discharge pipe and a valve. The outer side of the bottom of the mixing barrel is connected to the discharge pipe, and the valve is arranged on the discharge pipe.

[0008] Further description, it also includes a bolt bar and a return spring. The bolt bar is slidably connected to the valve, and a return spring is connected between the bolt bar and the valve. Two grooves are opened on the lower outer side of the mixing barrel, and the bolt bar and the groove cooperate to fix the valve state.

[0009] Further description, it also includes a cover plate and a handle. The hopper is provided with a cover plate, and the middle of the top of the cover plate is connected with a handle. The cover plate can prevent foreign matter from falling from the hopper into the mixing barrel.

[0010] Further explanation, it also includes an observation window, and the side wall of the mixing barrel is embedded with the observation window, through which the mixing status of the masterbatch raw materials inside the mixing barrel can be observed.

[0011] The beneficial effects of the utility model are as follows: the utility model drives the stirring rod to rotate forwardly through the servo motor, and at the same time, the stirring rod drives the first gear to rotate reversely through the second gear, thereby driving the stirring frame to rotate reversely through the inner gear ring. In this way, under the coordinated action of the forward rotation of the stirring rod and the reverse rotation of the stirring frame, the masterbatch raw materials can be stirred in both directions, thereby improving the mixing efficiency, and the fixed plate and the scraper rotate synchronously, which can scrape off the raw materials adhering to the inner wall of the stirring barrel, ensuring that the masterbatch raw materials can be fully stirred and mixed.

The bottom of the stirring frame 4 is connected to an inner gear ring 6. The bottom of the stirring barrel 1 is connected to a mounting plate 7. The mounting plate 7 is rotatably connected to a first gear 8 and a second gear 9. The first gear 8 is meshed with the inner gear ring 6. The second gear 9 is meshed with the first gear 8 and is connected to the stirring rod 3.
