Description
Technical Field
The invention relates to a ring spinning technology, in particular to a drafting mechanism for traversing lower pins and a spinning frame.
Background
In the prior ring spinning frame, the lower pin plays a role of supporting the lower apron to form a apron yarn guide mechanism, and in some new technical research and development, people cancel the design mechanism of the lower apron, but the lower pin also has a function of serving as a component forming a yarn guide channel.
Disclosure of Invention
The invention aims to provide a drafting mechanism for traversing lower pins, which expands the functions of the lower pins.
The invention also aims to provide a spinning frame with the transverse lower pin drafting mechanism.
A drafting mechanism for the horizontal moving lower pin is composed of front roller, front upper roller, middle and upper rollers, central roller of middle and upper rollers, back roller, back upper roller, upper pin, lower pin, slide seat for lower pin, horizontal moving supporting mechanism for lower pin, upper lattice ring, and tension unit for upper lattice ring.
Furthermore, the upper surface of the lower pin contacted with the upper grid ring is convex, and the upper grid ring covers the upper surfaces of the fixed rear lower pins and the movable front lower pins.
Furthermore, concave-convex lines vertical to the length direction of the lower pin are carved on the upper surface of the movable front lower pin covered by the upper grid ring.
Furthermore, the reciprocating stroke and the speed of the front lower pin can be adjusted.
Furthermore, the fixed rear lower pin and the movable front lower pin are connected by
A spinning frame of a drafting mechanism of a transverse lower pin, a drafting mechanism of three rollers and two zones comprises a front roller, a front upper roller, a middle upper roller, a rear upper roller, an upper grid ring tensioning device, an upper pin, a lower pin sliding seat and a transverse pin supporting driving mechanism of the lower pin, wherein the upper grid ring is sleeved on the upper pin and the middle upper roller and is tensioned by the upper grid ring tensioning device, the tensioned upper grid ring is tightly attached to the lower pin, the upper grid ring is driven by the middle upper roller to slide attached to the upper surface of the lower pin, the lower pin consists of a fixed lower pin and a movable lower pin, the fixed lower pin is arranged on a roller seat, the movable lower pin is parallel to the fixed lower pin, the movable lower pin is dragged by the transverse pin supporting driving mechanism of the lower pin, and makes reciprocating linear motion along the direction parallel to the fixed lower pin.
The invention has the following beneficial effects:
the invention provides a drafting mechanism and a spinning frame for traversing lower pins, wherein the width of fiber strands output by a front roller is relatively narrower when a ring spinning frame is used for spinning, and the hair of resultant yarn is less.
