The invention discloses a nonwoven equipment locating device. The nonwoven equipment without a balance mechanism, comprises a frequency changer, a motor and an eccentric gear. The motor drives the eccentric gear to rotate under the control of the frequency changer. the locating device comprises a first proximity switch, a second proximity switch, a sensing component and a control unit. The invention further discloses a control method of the nonwoven equipment locating device and nonwoven equipment. Compared with the prior art, the method only use two proximity switches to achieve precise locating after the nonwoven equipment without a balance mechanism shuTS down and can make a main shaft of the nonwoven equipment and the eccentric gear automatically stop at a random target position including the position of TDC. The method effectively improves the production efficiency and safety of the nonwoven equipment without the balance mechanism, is convenient for improving the present nonwovenequipment without the balance mechanism, and has great value in application.
