Description

Technical Field

[0001] This utility model relates to the field of granulation equipment technology, specifically to a granulation equipment for preparing anti-fogging masterbatch. Background Technology

[0002] The granulation equipment used for preparing anti-fogging masterbatch mainly consists of a twin-screw extruder. A twin-screw extruder comprises two meshing screws, a barrel, a feeding device, a transmission system, a heating and cooling system, and a control system. During the preparation of anti-fogging masterbatch, polymer resin, anti-fogging agent, dispersant, and other raw materials are added to the feeding device in a specific ratio. After entering the barrel, the raw materials are conveyed forward along the screw grooves under the rotation of the screws.

[0003] Meanwhile, the heating device outside the barrel heats the raw material to a molten state. The special structure and rotation direction of the two screws subject the material to strong shearing, mixing, and extrusion within the barrel, thereby achieving uniform dispersion of the anti-fogging agent in the polymer matrix. Finally, it is extruded through the die head and, after cooling and pelletizing processes, yields anti-fogging masterbatch.

[0004] However, in the existing cooling pelletizing process, the pellets produced by cutting are prone to accumulation during the cooling process. When the pellets accumulate together, they cannot fully contact the cooling medium, resulting in uneven cooling and low efficiency. This affects the quality and production efficiency of the anti-fogging masterbatch. Therefore, a pelletizing device for the preparation of anti-fogging masterbatch is proposed. Utility Model Content

The outer side of the wire mesh drum 13 near the drive gear 20 is fixed with a transmission gear ring 21, and the drive gear 20 and the transmission gear ring 21 are meshed and connected.

[0035] The second fan 18 is fixed to the outside of the second outer ring 16 by a frame;

[0036] The guide plate 17 is located at the output end of the wire mesh roller 13, and the guide plate 17 is fixed to the bottom plate 14 by the frame.

[0037] Please see Figure 2 The turntable 11 is rotatably connected to the wire mesh roller 13. A vibrator 12 is fixed on the outer side of the guide pipe 10 through the frame. The vibrator 12 is used to generate vibration and transmit it to the guide pipe 10 to accelerate the falling of particles and prevent particles from clogging in the guide pipe 10.

[0038] Please see Figure 1 The twin-screw extruder 1 is equipped with a feeding device 2 at its feed end, and the feeding device 2 is fixedly connected to the twin-screw extruder 1 by bolts. The feeding device 2 is used to feed the raw material into the twin-screw extruder 1.

[0039] Please see Figure 1 and Figure 2 A top cylinder 6 is installed at the upper end of the side shell 4, and the top cylinder 6 is sealed and fixed to the side shell 4.

[0040] Please see Figure 2 The top cylinder 6 is equipped with a first fan 7, and the first fan 7 is fixed to the top cylinder 6 by a frame. The first fan 7 generates airflow, thereby accelerating the fall of particles.
