Coiled polyester fiber packing device

The utility model relates to the technical field of polyester fiber production, in particular to a coiled polyester fiber packing device which comprises a box body and a motor, electric push rods are rotationally connected to the two sides of the inner wall of the box body, the tail end of a main shaft of the motor penetrates through the box body, the tail end of the main shaft of the motor is fixedly connected with one of the electric push rods, and the other end of the main shaft of the motor is fixedly connected with the other electric push rod. And one end of each of the pair of electric push rods is fixedly connected with a connecting block. According to the winding device, the winding roller drives the fixing rod to rotate through the fixing block in the rotating process, the fixing rod drives the gear to deflect by a certain angle every time the fixing rod rotates by one circle until the gear drives the rubber block to rotate by one circle to extrude the pressure sensor, the number of times of extrudin
