However, the requirements for the screw head are getting higher and higher. At present, the inner hole of the non-return ring in the existing standard screw head is a straight-through type, and the middle hole does not have a kneading R groove and a pin. Type, without kneading pins, the standard type of R grooves at the front end of the screw head is three or four R grooves, the standard type meson does not have kneading pins and kneading R grooves, so the existing The standard screw head has no mixing function or the mixing effect is not obvious

The invention discloses a planet mulling screw head, which comprises the screw head, a non-return valve and a meson, the screw head comprises a latitude circular ring, longitude mulling R grooves and a mulling pin 1, the latitude circular ring is positioned on a material passing position at the intermediate section of the screw head, the longitude mulling R groove is milled on the latitude circular ring, the mulling pin 1 is positioned between two longitude mulling R grooves, and the inner ring of the non-return valve comprises a latitude R groove, a longitude R groove and a mulling pin 2, and a tangency point of the latitude R groove and the longitude R groove is the mulling pin2. The planet mulling screw head of the present invention is capable of fully interlacing and mulling the plastic at a fusion state, color powder in the plastic can be uniformly diffusion dispersed, the mulling effect is increased, fusion index of the plastic is increased, and the product quality is improved.
Description
technical field [0001] The invention relates to a screw device for an injection molding machine, in particular to a planetary mixing screw head. Background technique [0002] With the increasing development of the plastic industry, screw heads have a very wide range of applications. However, the requirements for the screw head are getting higher and higher. At present, the inner hole of the non-return ring in the existing standard screw head is a straight-through type, and the middle hole does not have a kneading R groove and a pin. Type, without kneading pins, the standard type of R grooves at the front end of the screw head is three or four R grooves, the standard type meson does not have kneading pins and kneading R grooves, so the existing The standard screw head has no mixing function or the mixing effect is not obvious. Contents of the invention [0003] In view of the above-mentioned deficiencies existing in the current screw head, the purpose of the present inven...
