What is the function of the melting device of the polypropylene spinning machine?

Polypropylene spinning machine is used for spinning polypropylene filament (civilian yarn, industrial yarn, carpet yarn); including slice 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 material, melting of polymer, quantitative extrusion of melt.

(2) Three-stage screw: feeding section, compression section and metering section.

(3) The working principle of the screw extruder is the partition of the screw and the movement of the material in each zone of the screw.

① Feeding zone (solidification zone) equal depth screw.

② In the first half (cooling area), the jacketed coil or the inner core of the screw is connected with cooling water, and the temperature is less than 100 °C to prevent the material from prematurely melting and ringing and blocking the material to protect the screw transmission mechanism from heat.

③ The second half (preheating zone) prevents sudden changes in the temperature of the material from the feeding zone to the compression zone.

④ Compression zone (melting zone) The gradual or sudden change of screw melts the material (heating, shearing) and compresses (the volume of the screw groove becomes smaller); the air or water vapor is returned to the feeding zone.

⑤ Measuring area (homogenization area) and other shallow screws.
