Description

Technical Field

[0001] The utility model relates to the technical field of textile machinery and equipment, in particular to a high-speed fuel-saving aluminum rod spindle with a double liner structure. Background Art

[0002] The spindle is one of the main components for twisting and winding on a spinning machine. It is an assembly of a slender rotating shaft supported at two points. It is used to twist the fibers into yarn and wind the yarn around the bobbin into a certain shape. The number of spindles is usually used to indicate the size of the spinning mill. It is also called spinning spindle and sand spindle.

[0003] Among them, a spindle with publication number CN213327999U includes a spindle rod and a spindle disk, a yarn cutter and a yarn tube arranged on the spindle rod in sequence from bottom to top. It also includes a wire-paying shell installed in the yarn cutter. The outer wall of the wire-paying shell is in contact with the inner wall of the yarn cutter, and the wire-paying shell can be moved up and down without separating from the docking position with the yarn cutter. The yarn cutter and the wire-paying shell are provided with corresponding wire-clearing grooves that pass through their respective upper edges.

[0004] The above solution has the following shortcomings:

[0005] In the above technical solution, when the spindle rod rotates at high speed, the spindle oil adsorbed on the lower surface of the spindle rod will be continuously thrown out under the action of centrifugal force to form oil mist, thereby speeding up the consumption of the spindle oil.
