What is the function of the melting device of polypropylene spinning machine?
Polypropylene spinning machine is used for spinning polypropylene filament (civilian yarn, industrial yarn, carpet yarn); including chip extrusion melting (melt conveying), spinning, cooling (oiling), temperature control, frequency conversion control.
Detailed explanation of the melting device of polypropylene spinning machine:
(1) Function Supply of solid materials, polymer melting and melt quantitative extrusion.
(2) Three sections of screw: feeding section, compression section, and metering section.
(3) Working principle of screw extruder That is the division of the screw and the movement of the material in each area of the screw.
① Feeding area (curing area) constant depth screw.
② Front half (cooling zone) Jacketed coil or screw core is passed with cooling water, <100 ° C to prevent premature melting of the material and ring-blocking to protect the screw transmission mechanism from heat.
③ The second half (preheating zone) prevents sudden temperature changes from the feed zone to the compression zone.
④ Compression zone (melting zone) The gradual or abrupt screw melts the material (heating, shearing) and compresses (the screw groove volume becomes smaller); returns air or water vapor to the feeding zone.
⑤ Shallow screw such as measurement area (homogenization area).
