AI Technical Summary
When LFT-D material is granulated by water-cooled strips, the hardness of the strips leads to excessive load and easy locking of the pelletizer, and the high brittleness leads to excessive length of particles and easy blocking of the discharge port.
The guide strip device and the dispersion device are adopted. The guide strip device disperses the material strip through the guide roller and the press roller. The dispersion device prevents particles from being blocked through the spindle and the disc body, and drys the particles in combination with the air-drying device.
The orderly dispersion of the material strips into the pelletizer is achieved to prevent particles from being blocked and improve production stability and fluency.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of modified plastic processing equipment, and particularly relates to an LFT-D water-cooled strand pelletizing device. Background Art
[0002] Water-cooled strand is one of the most commonly used methods in the production of modified plastics. After being plasticized by a twin-screw extruder, the plastic goes through processes such as water cooling in a water tank, drying by an air dryer, and pelletizing by a pelletizer. The water tank is generally about 5 meters long and is connected to a circulating water tank through pipes, requiring a stable foundation and good load-bearing capacity of the water tank.
[0003] LFT-D materials generally contain 30% glass fiber and a certain amount of powder filling. When the materials are pelletized by water-cooled strand, their hardness and brittleness are relatively large. The current pelletizing methods have the following problems:
[0004] First, when the strands enter the pelletizer intensively, due to their large hardness, the load on the pelletizer is large, and it is extremely easy to cause a jamming phenomenon, resulting in shutdown.
[0005] Second, due to the large brittleness of the strands, the strands need to be cut into longer particles to avoid powder. If the pelletizing particles are too long, and at the same time, the particle surface is easily wetted with water, it is easy to cause blockage of the feeding port of the pelletizer.

The two ends of the rotating bearings are respectively slidably connected to the columns on both sides. Sliding limiting grooves for sliding cooperation with the rotating bearings are arranged on the columns, and pressure members are arranged on the columns.
