Description

Technical Field

[0001] The invention belongs to the field of masterbatch production, and in particular relates to a molding device for producing modified PP masterbatch. Background Art

[0002] The full name of masterbatch is plastic masterbatch, which is composed of excess chemical additives, carrier resins and dispersants. Masterbatch is an aggregate obtained by uniformly loading an excess amount of pigments (dyes) in the resin. Masterbatch refers to the granular material obtained by mixing and kneading various additives and fillers with a small amount of carrier resin in the process of plastic processing and molding for the convenience of operation, and then metering, mixing, melting, extruding, and pelletizing by extruders and other equipment. Modified PP masterbatch is a kind of masterbatch. In the production process, the long strips of masterbatch are cut and the cut ends are collected in small pieces.

[0003] The existing relevant patent, patent number CN202321921203.5 "A molding device for the production of modified PP masterbatch", has "The molding device for the production of modified PP masterbatch, through the setting of the blade, makes it easy to cut the long strip-shaped masterbatch, reducing the labor intensity of the user, and at the same time making the masterbatch cut to a uniform size. Through the coordinated setting of the lifting slot, the lifting seat, the lifting frame, the electric telescopic rod and the blade, when it is necessary to cut during use, the electric telescopic rod can be opened, and the extended end of the electric telescopic rod will drive the lifting frame to move downward, and the lifting frame will drive the lifting seat to move downward inside the lifting slot, and the lifting frame will drive the blade to move downward, so that the blade cuts the long strip-shaped masterbatch. When the cutting is completed, the electric telescopic rod is opened to restore the lifting frame to its original position. Position, start the servo motor, the output end of the servo motor will drive the lead screw to rotate, the lead screw will drive the sliding seat to move, the sliding seat will drive the push seat to slide inside the push groove, the push seat will drive the push plate to move on the top of the bracket, so that the push plate pushes the cut long strip masterbatch to the inside of the collection box, thereby reducing the fatigue of the user and achieving the purpose of improving work efficiency". However, it still has some shortcomings. In order to make several blades work, it is necessary to traction roller to control the long strip masterbatch to stretch to a certain length and then stop, and then wait until several blades fall and cut at the same time, and the broken masterbatch is discharged before feeding again.
