Description
Technical field
The utility model belongs to spinning machine part apparatus, especially keeps machine with a kind of rotor spinning machine connector winding tension
Structure is related.
Background technique
The Spinning Principle of rotor spinning machine is by ribbon shredding into single fiber, and single fiber is transported to revolution at a high speed with air-flow
Revolving cup in, in collection surface with draw yarn yarn tail and contact winding, resultant yarn is twisted, by drawing yarn axis and that draws that yarn roller forms draws yarn
Roller clamping is drawn, then is directly coiled into tube by winding device.
When there is broken yarn, need to carry out connector.Before connector, tube and draw yarn roller and lift, will manually be hung on heavy yarn electricity
Magnet, which is hung, draws yarn loose thread fixed length on loose thread, then opens spinning organ, is detached from revolving cup shaft and tengential belt and rubs, cleaning turns after stalling
Cup.When connector, spinning organ is closed, revolving cup shaft is driven by tengential belt and rotated, drawn yarn loose thread and be put into doffing tube.Joint signal is sent,
Revolving cup, the heavy yarn electromagnet that spinning organ fed agency feeds fiber to revolution at a high speed hang loose thread retraction releasing and hang yarn, make loose thread quilt
Vacuum suction reaches revolving cup by doffing tube and contacts winding with the fibrous ring of feeding, and twisting resultant yarn is drawn.
Tube is dropped on winding friction roller and is wound after connector success.Draw yarn roller and draws yarn axis rotation clamping yarn
It conveys to form yarn road to winding device, the arc-shaped tension compensating bar of support yarns and leading for reciprocal traversing is provided in yarn road
Loose thread, yarn are caught in the yarn guiding trough of yarn guide head, are guided in coiling and molding on tube by yarn guide head.Tube is straight when due to each connector
Diameter size has differences, and causes tube to fall and has differences with winding time for contacting of friction roller, start with the winding of setting and
The corresponding time relationship for drawing yarn starting generates deviation, and there are of short duration yarn tension deficiency, traversings when making to wind after connector starting
Yarn guide head be easy to produce can not the successful problem of a guide, cause that yarn winding is overlapped or skid off normal winding range climbs silk
Phenomenon influences tube Forming Quality, causes unwinding difficult.
