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, FDY) 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.

The purpose and characteristics of the drafting machine: It is suitable for drawing the fiber web which is overlapped by the mesh laying machine to make the orientation of the fiber change and improve the longitudinal and transverse strength ratio of the fiber web; it is a three-roll and five-group drafting form, each group drives independently, frequency conversion speed regulation, adjusting the drafting ratio is convenient and reliable, and the surface of the drafting roller is wrapped specially. Metal card clothing. The combined flat wire winding drafting machine with oven heating and hot rolling is a kind of drafting machine. The first draft of this drafting machine is designed as a portal frame structure. There is water mist in the portal frame with one pair of rolls extruding film, and the other pair of rolls or two pairs of rolls producing tension for the clamping film, which is convenient for wire splitting and cutting. The counter roll is pneumatic, and the solenoid valve opens and closes. The active roll of the opposite roll is traction roll, which is driven by DC motor. The wire splitting cutter adopts manual or electric pressing which can be transversely or horizontally pressed. The oven uses a hot air fan to circulate hot air for heat transfer. Outside the oven is a temperature display meter and a regulating circulation air valve. The oven is equipped with a temperature control display regulator. The heater is an electric heat pipe. Drawing machine is widely used in textile enterprises.

The utility model relates to a yarn pressing device of a drawing machine for polyester long yarn, which belongs to textile machinery components. Including rollers, bearings, roll shafts, swing arms and swing arm bases with friction rings, rollers are placed on the roll shafts through bearings and with large clamp springs, the roller shafts are fixed on the swing arms, the swing arms are hinged on the swing arm seat, and the swing arm seat is fixed on the lower beam of the stretcher. The feature is that it also includes a heating element shell. The shell is provided with a heater heated after electrification and the heating temperature can be adjusted. The pressing roller has a housing cavity for the heating element shell to accommodate. Advantages: The roller is heated by a heater, so that the polyester filament wound on the roller shows the effect of heating and drafting, so that the drafting and setting of polyester filament in the existing technology are synchronized in the form of secondary drafting and primary setting. The dry-heat shrinkage and boiling-water shrinkage of polyester filament obtained by the yarn pressing device were reduced from 13% and 8% to 2% and 3% respectively.
