The application relates to a flat pre-oriented
yarn production device and relates to the technical field of chemical
fiber spinning devices. The device comprises a rack, a
drying and crushing box, a sealing cover plate, a feeding port and a discharging box, further comprises a
drying unit and a crushing unit, the
drying unit comprises an upper layer mesh belt, a middle layer mesh belt, a lower layer mesh belt, a first driving motor, a second driving motor, a third driving motor and a drying mechanism; the crushing unit comprises a first crushing roller, a second crushing roller and a driving
assembly. The material of the flat pre-oriented
yarn production device enters the drying and crushing box through the feeding port first, is subjected to step-by-step drying treatment of the upper layer mesh belt, the middle layer mesh belt and the lower layer mesh belt, then reaches the crushing unit, is crushed by the first crushing roller and the second crushing roller, and finally is discharged through the discharging box, so that the whole process treatment from feeding to discharging is realized.
