Description

Technical Field

[0001] This utility model relates to the field of color masterbatch processing, specifically a mixing device. Background Technology

[0002] Masterbatch refers to granular material produced during plastic processing and molding by mixing various additives, fillers, and a small amount of carrier resin for ease of operation. This mixture is then metered, mixed, melted, extruded, and pelletized using equipment such as extruders. In the processing of film capacitors, which use plastic film as the dielectric, the plastic film is typically made by mixing masterbatch.

[0003] Patent CN220280142U discloses a mixing device for processing masterbatch. Its technical solution includes a mixing tank and a top cover. The top cover is fitted onto the top of the mixing tank, and a U-shaped frame is installed in the middle of the top cover. A stirring motor is installed in the middle of the top beam of the U-shaped frame. The output shaft of the stirring motor is connected to a stirring shaft via a flange. The stirring shaft passes through the top cover and is rotatably mounted thereto via a bearing seat. Five sets of stirring rods are symmetrically installed on the stirring shaft. Two threaded sleeves are symmetrically rotatably mounted inside both ends of the top cover via embedded bearings. Gears are installed at the upper ends of both threaded sleeves, and threaded rods are spirally connected inside the two threaded sleeves. A ring frame is installed at the bottom of the two threaded rods, and a ring-shaped rubber pad is embedded in the outer side of the ring frame. A discharge port is provided in the middle of the bottom of the mixing tank, and a sealing plate is inserted and installed at the discharge port. This utility model achieves automatic cleaning of the material inside the mixing tank, resulting in clean discharge and convenient cleaning.

[0004] However, existing patents have the following drawbacks:

[0044] The discharge port 9 is located at the bottom of the mixing tank 5, and the mixed masterbatch can be discharged from the discharge port 9 during use.

[0045] The hinge block 10 is fixedly connected to one end of the mixing tank 5. The two ends of the hinge rod 11 are hinged to the inside of the hinge block 10. The cover 12 is snapped onto the surface of the discharge port 9. The upper end of the cover 12 is fixedly connected to the lower end of the hinge rod 11.

The installation rod 619 is movably connected to the inner side of the installation plate 618. When the connecting shaft 605 starts to rotate, it drives the first bevel gear 611 to start rotating, thereby causing the second bevel gear 612 to start rotating in opposite directions, causing the third bevel gear 613 to start rotating in opposite directions with the first bevel gear 611, thereby causing the fixed shaft 614 to start rotating, thereby causing the second stirring rod 615 to start rotating, thereby causing the second stirring plate 617 to start rotating through the second stirring roller 616, thereby causing the first stirring plate 609 and the second stirring plate 617 to start rotating in opposite directions, so that the masterbatch in the mixing tank 5 can be fully stirred, and the degree of stirring of the masterbatch is improved.

[0048] The cleaning structure 7 includes a fixed rod 701 fixedly connected to the lower end of the fixed shaft 614. Several fixed plates 702 are fixedly connected to the lower surface of the fixed rod 701. A scraper 703 is fixedly connected to one end of the outer side of the fixed plate 702. The scraper 703 is in contact with the inner wall of the discharge port 9. When the fixed shaft 614 starts to rotate, it drives the fixed rod 701 to rotate, thereby causing the fixed plate 702 to rotate, which in turn causes the scraper 703 to rotate. This allows the scraper 703 to remove the masterbatch adhering to the discharge port 9, thus cleaning the discharge port 9 and preventing blockage.
