Description

Technical Field

[0001] This utility model relates to the field of color masterbatch processing, and in particular to a color masterbatch dehumidification dryer. Background Technology

[0002] Color masterbatch, also known as color masterbatch or color masterbatch material, is a polymer composite coloring material made by uniformly loading a high proportion of pigments or dyes onto a resin carrier and adding functional additives such as dispersants. The production process includes steps such as raw material preparation, mixing, plasticizing, extrusion, and granulation. In the granulation stage, the plasticized material is extruded into continuous strips, which are then cut into granules by a pelletizer to obtain color masterbatch. The produced color masterbatch generally needs to be dehumidified and dried by equipment to improve the stability of the pigments.

[0003] The reference patent title is: An Antistatic Masterbatch Dryer (Patent Publication No.: CN222628300U). The machine uses a motor to rotate a rod, which in turn drives the air duct and stirring blades to rotate via a support rod. The stirring blades agitate the masterbatch. A fan blows cold air into the heating chamber through a pipe, which is then heated into hot air by an electric heating wire. The hot air is then injected into the air duct through an air inlet and evenly discharged into the drying cylinder through air holes. This ensures that the masterbatch distributed in the drying cylinder is heated evenly, thereby accelerating the drying efficiency of the masterbatch and shortening the drying time.

[0004] However, the following problems exist when implementing the above technical solutions: the quality of the masterbatch dried by the above devices cannot be guaranteed; the above devices use stirring blades to drive all the masterbatch inside the drying cylinder to turn and move, which facilitates uniform heating and drying of the masterbatch, but stirring will increase the relative movement between the masterbatch, and friction between the masterbatch is unavoidable, which will cause damage or breakage to the surface of the masterbatch, and may also cause the pigment particles in the masterbatch to aggregate or redistribute, reducing the dispersibility of the pigment; it will affect the coloring effect of the masterbatch, resulting in uneven color or increased color difference in the product.

[0005] Therefore, this utility model proposes a masterbatch dehumidification dryer. Utility Model Content

[0006] This utility model provides a masterbatch dehumidification dryer, which can solve the problem that in the prior art, when the masterbatch is moved by the stirring blade to make the masterbatch uniformly heated, friction will occur between the masterbatches, which may damage the surface of the masterbatch or affect the coloring effect of the masterbatch.

Drying air is injected through the drying pipe and comes into direct contact with the masterbatch. The rotation of the drying cylinder 21 drives the drying rack 22 to rotate. After the drying rack 22 rotates to a certain angle, the masterbatch falls onto the surface of the placement rack 27 and comes into contact with the drying air. After the masterbatch is dried, when it is taken out, the locking ring 55 is rotated first to cause the locking ring 55 to disengage from the single semi-cylinder 53. The locking rod 51 disengages from the locking groove 52 under the action of the return spring 56. The control cylinder 61 causes the piston rod to retract, driving the transfer block 41 to rotate, causing the placement rack 27 to rotate, and the masterbatch falls.
