Detailed Description
The present invention will be described in detail with reference to fig. 1 and 2, and the exemplary embodiments and descriptions of the present invention are provided to explain the present invention and not to limit the present invention.
The utility model provides a round pin on ring spinning, it is including gripping the reversing frame 1 at leather roller (not shown in the figure) middle part and setting up the groove 2 that slides at this reversing frame both ends respectively, the cover is established two leather collars (not shown in the figure) at leather roller both ends slide through the groove that slides that corresponds it is equipped with elastic tensioning frame 3 to lie in each groove upside that slides on the reversing frame, and this tensioning frame carries out the tensioning to the leather collar that corresponds, and its tensioning direction forms 30-90 contained angle with the draft plane direction of keeping silent for the line of keeping silent can not take place to float, thereby keeps silent the elastic type among the prior art and changes into keeping silent fixedly, has guaranteed the stability of draft floating zone.
Preferably, the tensioning frame 3 is mounted on the rotary frame through a spring 4, and the tensioning frame can stretch and retract along the tensioning direction through the spring, so that the leather ring is ensured to have better tension in the operation process, and the leather ring can be prevented from arching. The spring is arranged in a direction that the elastic direction of the spring forms an included angle of 30-90 degrees with the drawing plane direction of the jaw, so that the tensioning direction of the spring and the drawing plane direction of the jaw form a corresponding included angle. In the implementation process, the tensioning frame and the rotary frame are connected in a detachable mode, so that the tensioning frames with different sizes can be replaced, and if a large-diameter small-width leather roller and a small-width leather ring can be adopted during spinning, the running synchronization rate of the leather ring is improved, the pressurization of a middle roller is reduced, the torsional vibration is reduced, the yarn quality is improved, and the energy consumption is reduced. In the implementation process, the distance between the central axis for gripping the leather roller of the revolving frame and the wing plate 5 of the revolving frame can be set to be 15.5-18mm so as to adapt to the leather roller with large diameter.
In the implementation process, the tensioning steel needle 6 capable of tensioning the leather collar is arranged on the tensioning frame, so that the leather collar can be further tensioned, and the friction force between the leather collar and the tensioning frame can be reduced. Particularly, the tensioning steel needle is fixedly embedded on the tensioning frame, if the tensioning steel needle is fixed in an injection molding mode, the tensioning steel needle is convenient to process and install, and the tensioning steel needle is hardened through quenching and has a smooth surface through fine grinding, so that the sliding friction force between the tensioning steel needle and the leather ring is relatively small, the running resistance of the leather ring can be reduced, and the abrasion of the leather ring can be reduced. Preferably, the tensioning steel needle is rotatably connected with the tensioning frame in a manner that two grooves are formed in the tensioning frame, two ends of the tensioning steel needle are arranged in the corresponding grooves, and the groove width of each groove is larger than the diameter of the tensioning steel needle, so that the tensioning steel needle can rotate in the grooves, friction between the leather collar and the tensioning steel needle is changed into rolling friction, and abrasion is reduced.
Preferably, a jaw steel needle 7 is arranged in the sliding groove 2 at the jaw to reduce the abrasion of the leather ring at the jaw line. Specifically, the jaw steel needle is rotatably connected with the sliding groove, and the rotary connection mode can adopt a groove form arranged on the tensioning steel needle or other modes, so that the friction between the leather ring and the jaw line is changed into rolling friction, and the abrasion is reduced. The jaw steel needle can also be fixedly embedded on the sliding groove, such as fixed by adopting an injection molding mode and the like; as the jaw steel needle is hardened by quenching and the surface is fine-ground and smooth, the wear resistance of the steel needle is enhanced, and the friction force between the smooth surface and the leather ring is small, so that the wear can be reduced.
