Description

Technical Field

[0001] The utility model belongs to the field of screening devices, in particular to a particle screening device for a masterbatch granulator. Background Art

[0002] Masterbatch is a plastic colorant made of a high proportion of pigments or additives and thermoplastic resins that are well dispersed. The selected resin has a good wetting and dispersing effect on the colorant and has good compatibility with the colored material. The masterbatch needs to be screened in multiple layers through a screening device during the granulation process.

[0003] A Chinese patent with announcement number CN219748601U discloses a particle screening device for a masterbatch granulator, comprising an outer frame, two transverse guide rods are fixed on the inner side of the outer frame, two sliders are symmetrically slidably connected to the outer ends of the two transverse guide rods, a sieve plate is fixed on the upper side of four sliders, and one end of the four sliders is connected to a first spring sleeved on the outer side of the transverse guide rod, a vibration motor is installed at the lower end of the sieve plate, and also includes; a particle dispersion mechanism, which is arranged at one end of the upper side of the sieve plate. The utility model has a novel design and an ingenious structure. Hot air is generated by a hot air blower and blown toward agglomerated particle clusters through an air outlet pipe to heat the particle clusters. At the same time, the particle clusters are pressed and ground through a particle dispersion mechanism to disperse the particle clusters into small particles, which are convenient for screening out from the sieve holes and improve the screening effect. However, the particle screening device of the masterbatch granulator in the application squeezes the masterbatch particles through grinding teeth, which easily causes the masterbatch particles after extrusion to still fail to reach the appropriate specifications and fall from one end of the sieve plate, affecting the screening effect of the masterbatch particles.

[0004] In view of this, the present utility model is proposed. Utility Model Content
