Description

Technical Field

[0001] The utility model relates to the technical field of screening devices, in particular to a screening device which is convenient for collection. Background Art

[0002] Masterbatch is a new type of colorant specially used for polymer materials, also known as pigment preparation. Masterbatch is composed of three basic elements: pigment or dye, carrier and additive. It is an aggregate obtained by uniformly loading an extraordinary amount of pigment into a resin, which can be called a pigment concentrate. Therefore, its tinting power is higher than that of the pigment itself. After production, masterbatch must be screened through a screening device in order to select masterbatch that meets the specifications in shape and size for packaging and sale.

[0003] For example, a screening device for masterbatch production with publication number CN218518989U includes: a base, through the arrangement of a first deceleration protrusion and a second deceleration protrusion, the residence time of the masterbatch on the first sieve plate and the second sieve plate can be increased, the screening quality can be improved, and the arrangement of the universal wheel facilitates the movement of the device;

[0004] The screening device for masterbatch production realizes the unloading and screening of masterbatch by arranging an inclined first screen plate and a second screen plate to cooperate with a vibration motor. However, with this screening method, when a large amount of masterbatch raw materials enter the vibration frame from the hopper, a part of the masterbatch that meets the standards is blocked by the materials below that do not meet the standards, and is also easy to move on the first screen plate together and be discharged from the first discharge port, thus reducing the screening effect of the masterbatch. At the same time, since the first discharge port and the second discharge port are far away from the storage box, and the vibration frame is in a continuous vibration state when working, the masterbatch raw materials are not easy to fall into the storage box after being discharged from the first discharge port and the second discharge port, but will fly to the outside, which is not convenient for collection.
