Suzhou Zhan Heng Intelligence to introduce to you: In general, what are the components of our spinning machine? 

 The general spinning machine itself has 4 functional areas. 

 ① Polymer melting device: screw extruder. 

 ② Melt transport, distribution, spinning and insulation devices: bending pipe, spinning box (melt distribution pipe, metering pump, spinning head assembly). 

 ③ Wire device: spinning window and sleeve.

 ④ Wire collection device: wet oil mechanism, wire guide structure, winding machine or wire receiving device. 

 Melting plant

 (1) The role of solid material supply, polymer melting, melt quantitative extrusion. 

 (2) Screw three sections feed section, compression section, metering section. 

 (3) The working principle of the screw extruder is the partition of the screw and the movement of the material in the various areas of the screw. ① Feed area (curing area) and other deep screw. ② The first half (area) of the jacket coil or the inner core of the screw through water, < 100℃ to prevent premature melting of the material and ring blocking material to protect the screw transmission mechanism from heat. ③ The latter half (preheating zone) prevents the temperature mutation of the material from the feed zone to the compression zone. (4) compression zone (melting zone) gradual or abrupt screw melt material (heating, shearing) and compression (screw groove volume becomes smaller); Return air or water vapor to the feed area. ⑤ Measurement area (homogenization area) and other shallow screw. Melt conveying, distributing, spinning and insulation equipment (1) The melt conveying pipe from the bending screw extruder to the spinning box (one end is connected to the screw outlet and the other end is connected to the spinning machine melt distribution pipe) - the biphenyl-diphenyl ether mixture in the jacket is heated (melt insulation). (2) Spinning box melt distribution pipe ten biphenyl heating box ten spinning pump and its transmission device ten spinning head assembly. ① Principle of melt distribution tube ② Ensure that the melt reaches the same distance to each spinning site. The melt has a short residence time in the distribution tube. Less retraction. ③ The form of melt distribution tube branch type, radiation type. (3) Heating of the spinning box (biphenyl heating box) ① Heat preservation and heating effect on melt distribution pipe, metering pump and spinning head assembly. ② Method biphenyl - diphenyl ether heat carrier (biphenyl/diphenyl ether - 26.5 percent /73.5 percent), heated with an electric heating rod. ③ Heat preservation 80 ~ 100mm insulation layer, filled with ultrafine glass fiber or other insulation materials. (4) metering pump high temperature gear pump. (5) Spinning head assembly ① Filter the melt to prevent the blockage of the spinneret hole, the melt is fully mixed, the difference in melt viscosity is reduced, and the melt is evenly dispersed into each small hole of the spinneret hole to form a trickle of melt. ② Structural spinneret + melt distribution plate + melt filter material + assembly sleeve. Heating of spinning box (biphenyl heating box) ① Heat preservation and heating effect on melt distribution pipe, metering pump and spinning head assembly. ② Method biphenyl - diphenyl ether heat carrier (biphenyl/diphenyl ether - 26.5 percent /73.5 percent), heated with an electric heating rod. ③ Heat preservation 80 ~ 100mm insulation layer, filled with ultrafine glass fiber or other insulation materials. Filament device (1) The spinning window makes the filament only subject to directional, quantitative and qualitative air flow in the process, the rate is uniform, and the solidification position of the fiber is fixed (not affected by the surrounding air flow). (2) The lower part of the slow cooling chamber is provided with two insert plates, so that it is separated from the spinning cylinder, and the upper part is provided with a lock, so that the slow cooling zone is formed under the spinneret; Length 30~200mm; Prevent wind from blowing cold spinneret surface, reduce winding wire birefringence and improve stretchability.
