Fuente: WIPO "hemp" The utility model discloses a broken yarn automatic stop detection mechanism of a linen yarn winding machine, which is equipment adopting the winding machine and comprises a detection support, an inner side reinforcing frame is welded on the inner side of the bottom of the detection support, an anti-vibration pad is fixedly mounted at the bottom of the detection support, and a detection mounting frame is fixedly mounted on the inner side of the inner side reinforcing frame. An angle adjusting frame is rotatably mounted on one side of the detection mounting frame, a spinning contact wheel is mounted on the outer side of the angle adjusting frame, a detection transverse plate is mounted on the outer side of the detection mounting frame, an automatic detector is fixedly mounted on the outer side of the detection transverse plate, a rear roller is mounted on the inner side of the detection mounting frame, and hemp gauze is arranged between the rear roller and the spinning contact wheel in a contact manner; mounting penetrating rods are welded to the inner sides of the detection supports, top connecting rods are fixedly mounted at the top ends of the detection supports, and bottom leveling frames are fixedly mounted on the outer sides of the detection mounting frames. The utility model solves the problems that the bobbin winder cannot realize broken yarn detection in the spinning process, and the surface of the linen yarn cannot be leveled.
