Technical Field

[0001] The utility model relates to the technical field of masterbatch feeding equipment, in particular to an online masterbatch adding device. Background Art

[0002] Masterbatch is a pigment used to color plastic products, usually in the form of granular or particulate matter. They are composed of pigments or pigments, carrier resins and additives, and are used to color colorless or transparent plastic products to meet different aesthetic and functional requirements.

DETAILED DESCRIPTION

[0020] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] Example

[0022] like Figure 1-4As shown, the utility model proposes an online masterbatch adding device, including a loading rack 1, an inner cavity 11 is provided in the loading rack 1, and the upper end of the inner cavity 11 is an open structure, a loading port 6 and a reflux port 7 are provided on the side wall of the inner cavity 11, and the two are symmetrically distributed, a rotating sleeve 8 is rotatably connected in the inner cavity 11 and aligned with the loading port 6, a through hole 81 is provided on the side wall of the rotating sleeve 8, a lifting plate 2 is slidably connected in the inner cavity 11 and located below the loading port 6, a threaded rod 3 is fixed at the bottom of the lifting plate 2, and a threaded sleeve is rotatably connected at the bottom of the inner cavity 11 4. The bottom of the threaded rod 3 is threadedly connected in the threaded sleeve 4. A servo motor 5 for driving the threaded sleeve 4 to rotate is fixed at the bottom of the loading rack 1. A pair of limit rods 25 are fixed at the bottom of the lifting plate 2. The bottom of the limit rods 25 are slidably connected to the bottom of the inner cavity 11. A support frame 12 is fixed to the outer periphery of the bottom of the loading rack 1. A feeding hopper 13 is fixed to the upper end of the loading rack 1. An addition pipe 61 is fixed on the outer wall of the loading rack 1 and aligned with the feeding port 6. The outer side of the addition pipe 61 is tilted downward. An observation window 14 is provided on the side wall of the loading rack 1 and aligned with the inner cavity 11.

[0023] A vibration plate 21 is arranged above the lifting plate 2, a vibration sheet 24 is fixed at the bottom of the vibration plate 21, a guide rod 22 is fixed at the bottom of the lifting plate 2, the bottom of the guide rod 22 is slidably connected in the lifting plate 2, a vibration spring 23 is fixed between the vibration plate 21 and the lifting plate 2, and the vibration spring 23 is located on the outside of the guide rod 22.

[0024] A driving groove 9 is opened in the side wall of the inner cavity 11 and aligned with the bottom of the rotating sleeve 8. The outer side wall of the bottom of the rotating sleeve 8 is located in the driving groove 9 and is fixed with a bevel gear sleeve 82. The side wall of the driving groove 9 is rotatably connected with a driving bevel gear 91, and the driving bevel gear 91 is meshed with the bevel gear sleeve 82. A stepper motor 92 is fixed to the outer side wall of the loading rack 1, and the output end of the stepper motor 92 is fixed on the driving bevel gear 91.

[0025] In this embodiment, the entire device is first connected to an external power supply, and then the masterbatch is poured into the inner cavity 11 through the feed hopper 13. At this time, the rotation of the rotating sleeve 8 can align the perforation 81 with the reflux port 7 to ensure that a certain amount of masterbatch enters. When adding is required, the rotating sleeve 8 rotates to align the perforation 81 with the feed port 6. At this time, the servo motor 5 is used to drive the threaded sleeve 4 to rotate. Under the limit of the limit rod 25, the lifting plate 2 moves upward. At this time, the masterbatch in the inner cavity 11 will be discharged from the feed port 6 and finally enter the processing equipment through the diversion of the adding pipe 61. The height of the lifting plate 2 is proportional to the amount of masterbatch added, so quantitative addition of different components can be achieved, and the operation is simple and convenient.
