[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 in the resin. Masterbatch refers to the granular material obtained by mixing and kneading the required various additives, fillers and a small amount of carrier resin in the process of plastic processing and molding for the convenience of operation, and then measuring, mixing, melting, extruding, and pelletizing through extruders and other equipment. Plastic masterbatch will be melted during production and processing, so melting equipment will be used. Generally, plastic masterbatch is directly added to the melting equipment, and after melting is completed, the material is discharged, and then another batch of plastic masterbatch is melted.

[0023] Reference Figure 1-4 The utility model embodiment is a polymer plastic masterbatch melting device, which includes: a fuse tube 1, a motor 2 is provided on one side of the fuse tube 1, a support leg is fixedly connected to the bottom end of the motor 2, a discharge pipe 3 is connected through the other side of the shell 501, a base is provided at the bottom end of the fuse tube 1, a connecting plate 4 is provided at the top end of the fuse tube 1, and a preheating feed assembly 5 is fixedly connected through the upper surface of the connecting plate 4;

[0024] The preheating feed assembly 5 includes a shell 501, and an insulating layer 5011 is adhered to the inner wall of the shell 501 to prevent the staff from touching the shell 501 and getting burned. A plurality of heating rods 502 are provided along the central axis at the inner bottom end of the shell 501, and a plurality of heating rods 503 are fitted on the inner wall of the shell 501. A feed pipe 505 is spirally wound around the outer wall of the plurality of heating rods 502. The feed pipe 505 is made of copper to improve the thermal conductivity. The outer wall of the heating rod 503 fits the outer wall of the feed pipe 505. The top end of the feed pipe 505 passes through the top end of the shell 501 and is connected with a feed hopper 504. A cover 506 is rotatably connected to one side of the top end of the feed hopper 504. A handle 507 is fixed to the top end of the cover 506. The bottom end of the feed pipe 505 passes through the bottom end of the shell 501 and the bottom end of the connecting plate 4 in sequence and is connected with the fuse tube 1. By means of the preheating feed assembly 5, when the plastic masterbatch is being melted, it is put into the feed hopper 504, and the plastic masterbatch will fall into the spirally arranged feed tube 505. At the same time, the heating rod 1 502 and the heating rod 2 503 will heat the outer wall of the feed tube 505 at the same time, and the heat is transferred to the plastic masterbatch through the feed tube 505 to preheat it. The plastic masterbatch is preheated before falling into the fuse tube 1 in the feed tube 505, and there is no need for interval feeding, thereby improving the melting efficiency. By means of the set feed tube 505, since the plastic masterbatch will roll down in the feed tube 505, the heating surface of the plastic masterbatch will change, so that it will be heated more evenly, thereby improving the preheating efficiency.

[0025] Working principle: When in use, the plastic masterbatch is put into the feed hopper 504, and the plastic masterbatch will fall into the spirally arranged feed tube 505. At the same time, the heating rod 1 502 and the heating rod 2 503 will heat the outer wall of the feed tube 505 at the same time. The heat is transferred to the plastic masterbatch through the feed tube 505 to preheat it. Since the plastic masterbatch will roll down in the feed tube 505, the heated surface of the plastic masterbatch will change, making it heated more evenly. The plastic masterbatch is preheated before falling into the fuse tube 1 in the feed tube 505. The preheated plastic masterbatch will fall into the fuse tube 1 for melting, without the need for interval feeding, thereby improving the melting efficiency.
