Description

Technical Field

[0001] The utility model belongs to the technical field of masterbatch storage, and particularly relates to a masterbatch storage device with a screening function. Background Technique

[0002] Masterbatch, also known as color masterbatch or color concentrate, is a new type of special colorant for polymer materials, also known as pigment preparation. Masterbatch is mainly used in plastics and is composed of three basic elements: pigment or dye, carrier, and additive. It is an aggregate obtained by evenly loading an excessive amount of pigment onto resin, and can be called 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 desired pigment concentration in the colored resin or product. Masterbatch usually needs to be stored in a storage device for standby during production or use. After the masterbatch is produced, it is transported from the production line to the storage bin. Although the screening component will remove the masterbatch with unqualified particle size after leaving the production line, the masterbatch is not completely cooled and shaped at this time. As the masterbatch is transported to the storage bin, it completely cools, and there is a phenomenon that some masterbatch with unqualified particle size is transported into the storage bin, which affects the qualification rate of the masterbatch in the storage bin.

[0003] Chinese Patent with the publication number CN216760461U discloses a finished product storage device for breathable masterbatch, including a frame, a storage bin fixedly connected to the frame, and a transmission component for transporting the masterbatch to the storage bin. The storage bin is provided with a storage cavity for storing the masterbatch, and also includes a first screening component for screening the masterbatch and an aggregate cavity for collecting the undersize masterbatch. The first screening component is arranged between the discharge port of the transmission component and the storage cavity, the storage cavity is arranged directly below the discharge end of the first screening component, and the aggregate cavity is arranged directly below the screen holes of the first screening component.

[0004] However, during the storage of traditional masterbatch, the masterbatch is transported to the vibrating screen at the bin mouth of the storage bin by a screw conveyor, and then screened by the vibrating screen and transported to the storage bin for storage. However, in actual use, we found that there are still some deficiencies in this traditional storage device. For example, although the aggregate cavity with an aggregate outlet provided on the storage bin can collect the unqualified masterbatch after screening, in actual operation, we found that the aggregate cavity is prone to incomplete discharge during the discharging process, and it is very inconvenient to manually hold the aggregate cavity every time when discharging and collecting. Secondly, since the aggregate cavity is arranged inside the storage bin and the vibrating screen is installed, the bin mouth of the storage bin cannot be closed, so it is easy to enter a large amount of dust during storage.

This is the open state. When storing and protecting, the protection cover 702 moves rightward on the storage bin 2 and inserts, so as to facilitate the dust protection of the masterbatch in the storage bin 2;

When feeding, the masterbatch can be screened by the vibrating screen 10, and the qualified materials after screening can enter the storage bin 2 for storage. During the screening process of the vibrating screen 10, after the unqualified materials enter the material guiding frame 111 directly below the screening part, then through the material guiding pipe 112 at the lower end of the material guiding frame 111, they can directly enter the collection box 113 for collection. When the unqualified materials enter the collection box 113, they will be relatively loose in the storage effect. By using the output end of the second electric push rod 133 to reciprocally stretch and drive the moving seat 132 inserted with the collection box 113 to continuously slide and shake inside the chassis 131, the collection effect of the unqualified materials can be made more compact;
