The drafting machine is a mechanical device used for the drawing and twisting process in the production process of nylon, polyester and polypropylene multifilament. The polyester, nylon and polypropylene yarns (POY, UDY) spun from the spinning machine are stretched and twisted to have a certain linear density (denier), strength, elongation and other physical properties, which can be directly or added. Used for weaving after bombing.

Use and characteristics of the drafting machine: It is suitable for longitudinally stretching the web outputted by the laminating machine stack to change the orientation of the fiber and improve the longitudinal and transverse strength ratio of the web; for the three-roll five-group drafting form Each group is independently driven, frequency control, adjustable drafting ratio is convenient and reliable, and the surface of the drafting roller is coated with special metal card clothing. The oven heating hot rolling type combined flat wire winding drafting machine is a kind of drafting machine. The drawing of the drafting machine is designed as a door frame structure, and the water mist of the pair of roller extrusion film is arranged in the door frame. The other pair of rollers or the two pairs of rollers generate tension for the clamping film to facilitate the cutting of the wire. The counter roller is pneumatic and the solenoid valve is closed. The driving roller of the pair of rollers is a traction roller, which is driven by a DC motor. The wire-cutting tool is manually or electrically pressed in a lateral direction. The oven uses a hot air blower to circulate hot air for heat transfer. There is a temperature display table and a regulating circulation air volume valve outside the oven, and the oven is equipped with a temperature control display regulator. The heater is an electric heating tube. Drafting machines are widely used in textile companies.

A yarn drawing device for a drafting machine for drafting a polyester long yarn belongs to a textile mechanical component. The utility model comprises a pressure roller with a friction rolling ring, a bearing, a pressure roller shaft, a swing arm with a handle and a swing arm seat. The pressure roller passes through the bearing and is placed on the pressure roller shaft by a large circlip, and the pressure roller shaft is fixed on the roller shaft. On the swing arm, the swing arm is hinged on the swing arm seat, and the swing arm seat is fixed on the lower beam of the drafting machine, and is characterized in that it further comprises a heating element housing, wherein the housing is provided with heating and heating temperature after being energized. An adjustable heater having a heating element housing cavity for housing the heating element housing. The utility model has the advantages that the heating roller presses the pressure roller to make the polyester yarn wound on the pressure roller exhibit the effect of heating drafting, so that the form of the drawing and the shaping phase of the polyester filament in the prior art is changed to the second time. Drafting, one-time shaping. According to the test of the polyester filament obtained by the yarn pressing device, the dry heat shrinkage rate and the boiling water shrinkage ratio were reduced from the original 13% and 8% to 2% and 3%, respectively.
