During actual work, the motor 40 is started to drive the fiber winding drum 30 to rotate so as to drive the steel wire rope to wind and unwind, and the clothes hanger 20 is lifted and lowered during winding and unwinding of the steel wire rope.
Preferably, an X-shaped telescopic assembly is connected between the laundry stand 20 and the main frame 10 to improve the stability of the laundry stand 20 during lifting.
As shown in fig. 4 to 6, the motor braking system 300 of the clothes drying machine includes an output shaft 41 of the motor 40 and a braking component 50 located at the front end of the output shaft 41, the braking component 50 includes a one-way bearing 51 and a damping sleeve 52, the one-way bearing 51 is seated on the output shaft 41, and the damping sleeve 52 is sleeved outside the one-way bearing 51; when the airing rod 21 of the clothes hanger 20 is in a rising state, the output shaft 41 of the motor 40 rotates in the positive direction relative to the one-way bearing 51; when the airing rod 21 descends, the output shaft 41 of the motor 40 and the one-way bearing 51 rotate reversely at the same time and overcome the friction force of the damping sleeve 52 on the one-way bearing 51; when the airing rod 21 descends, the motor 40 is in a stop state, and the damping sleeve 52 resists the output shaft 41 of the motor 40 from continuously rotating reversely due to the friction force of the one-way bearing 51 to realize the braking effect.
The one-way bearing 51 of the brake assembly 50 is seated on the output shaft 41 of the motor 40, the airing rod 21 rises, the output shaft 41 rotates in the positive direction, and at the moment, the one-way bearing 51 cannot rotate; when the airing rod 21 descends, the output shaft 41 rotates reversely, and the output shaft can synchronously rotate reversely; the damping sleeve 52 is sleeved outside the one-way bearing 51 to generate certain frictional resistance to the rotation of the one-way bearing 51; when the motor 40 drives the airing rod 21 to descend, the output shaft 41 and the one-way bearing 51 rotate reversely at the same time, the one-way bearing 51 driven by the driving force of the motor 40 can overcome the frictional resistance of the damping sleeve 52, and when the motor 40 stops working and the driving external force exerted on the one-way bearing 51 disappears, the frictional force exerted on the one-way bearing 51 by the damping sleeve 52 can prevent the one-way bearing 51 from further driving the output shaft 41 to continue to rotate reversely in an inertia manner.
Preferably, the outer side of the damping sleeve 52 is sleeved with a torsion spring 53, and when the one-way bearing 51 rotates in the opposite direction, the torsion spring 53 has an inward compression extrusion force on the damping sleeve 52; further enhancing the frictional resistance exerted by the damping sleeve 52 on the one-way bearing 51, and then preventing the inertial rotation of the output shaft 41, thereby improving the braking effect on the clothes hanger 20.
