[0006] A chemical fiber stretching device includes an integrated frame, on which a plurality of temperature control rollers and a pulling roller are rotatably arranged, and chemical fiber yarns are wound around the temperature control rollers and the pulling rollers. Heat transfer oil is arranged in the temperature control rollers and the pulling rollers for heating the chemical fiber yarns for facilitating stretching. When the chemical fiber yarns pass through this device, they will be heated and stretched.
[0007] Preferably, a plurality of pulling grooves are provided at intervals on the pulling roller so that the chemical fiber filaments can be separated and arranged one by one to avoid entanglement during the stretching process.
[0008] Preferably, a suspension arm is provided on the integrated frame by welding or bolting.
[0009] Preferably, two electric push rods are arranged at intervals on the boom.
[0010] Preferably, a cooling and shaping roller is rotatably provided between the lower ends of the electric push rods. The cooling and shaping roller is made of stainless steel. The chemical fiber yarn is clamped on the temperature control roller to quickly cool the chemical fiber yarn, and the heat is finally quickly dissipated into the air through air cooling, so that the chemical fiber yarn is quickly cooled and shaped.
[0011] Preferably, the surface temperature of the pulling roller is greater than the surface temperature of the temperature-controlled roller, and the ductility of the chemical fiber filament is improved by heating to facilitate stretching.
[0012] The advantages and positive effects of the utility model are: the chemical fiber yarn gradually reaches a good stretching stage through segmented heating, and when the chemical fiber yarn reaches a certain stretching rate, it reaches the cooling and shaping roller and contacts with the cooling and shaping roller to quickly cool down and shape.
