Abstract

The utility model relates to a drafting device of a spandex warping machine. The drafting device is characterized in that a right head of a central shaft of a lower drafting roller is assembled in a central hole of a bearing of a tension sensor which is fixed on a right support; and a drive gear is arranged at the left side of a barrel body of an upper drafting roller, and a driven gear which is meshed with the drive gear is arranged at the left side of the barrel body of the lower drafting roller. Because the tension sensor is assembled on the right end of the lower drafting roller, when the yarn sheet drafting linear velocity which is generated by a drafting motor is larger than the yarn sheet backing-off linear velocity which is generated by a backing-off motor according to a certain proportion under the control of an electrical apparatus control system, when tension forces which are generated by the yarn sheets during the operation are applied on the lower drafting roller and the right head of the central shaft of the lower drafting roller, the tension sensor dynamically tracks in real time and feeds back to the electrical apparatus control system to change the velocity of the backing-off motor, so that cheeses are smoothly backed off at high speed, and the yarn sheets are drafted at constant tension force and constant linear velocity; and moreover, a tension detection device is simple in structure and convenient to disassemble and assemble as well as maintain.
