The utility model relates to the technical field of
cotton thread production, and discloses a humidifying device for pure
cotton thread production, which comprises a uniform humidifying mechanism, a sliding humidifying mechanism and a controller, one end in the sliding humidifying mechanism is slidably connected with the uniform humidifying mechanism, one end of the sliding humidifying mechanism is provided with the controller, and the other end of the sliding humidifying mechanism is connected with the controller. The uniform humidifying mechanism comprises a
moving frame, hanging sliding blocks are fixedly connected to the two ends of the upper end face of the
moving frame, a sliding groove is fixedly connected to the lower end of the end face of one side of the
moving frame, a sliding water conveying
pipe is slidably connected to one side of the outer wall of the sliding groove, and a plurality of nozzles are formed in the lower end face of the sliding water conveying
pipe. According to the device, the controller drives the first
servo motor to drive the eccentric wheel to rotate, the eccentric wheel pushes the sliding water conveying
pipe and the spray head to reciprocate along the sliding groove through the pull rod, an external
water source is supplied to the spray head through the water inlet, cotton threads are evenly humidified in the reciprocating spraying process, and therefore the quality of the cotton threads and the practicability of the device are improved.
