Description

Cradle assembly for a traction device of a spinning machine Technical Field The utility model relates to the technical field of cradle assemblies of spinning machines, in particular to a cradle assembly of a traction device for a spinning machine. Background The drawing device (also called as a drawing device) of the spinning machine is one of core components in the spinning process, and mainly aims to draw and thin the roving or sliver to the required fineness, straighten and parallel the fiber, and simultaneously control the movement of the fiber to ensure the quality of finished yarn; the cradle assembly in the traction device applies pressure to the leather roller through the pressurizing device, so that the leather roller is tightly matched with the roller to form a roller-leather roller jaw, thereby holding the fiber bundle, during spinning, the rear roller feeds the roving or sliver, the front roller rotates at a higher speed, and the middle roller and the leather collar control the movement of the fiber under the action of the cradle, so that the fiber is gradually drawn and thinned in the drawing zone. However, in practice, it has been noted that the pressing means at the end of the cradle are in close contact with the leather roller, and the reaction force will exert an upward force on the end of the cradle, and most of the cradle is currently sleeved on the fixed rod of the spinning machine, and when the reaction force is applied for a long time, the cradle may rotate reversely on the fixed rod, so that the pressure of the pressing means is affected.
