Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of textile machinery, in particular to a novel connection structure of a core yarn guide roller. Background Art
[0002] When the spinning machine is used to produce spandex core-spun yarn, the problems existing in the core-spun yarn guide roller structure of the existing equipment are immediately revealed. Specifically, the connection between the guide rollers often fails, causing the guide rollers to stop rotating, spandex yarn to break, and the coreless yarn spun to cause a large number of wrinkled fabrics and bad yarns in skirts. At the same time, due to the wear and deformation of the guide rollers, it is very difficult to repair and disassemble the machine, causing downtime and affecting production. The reason is that the guide rollers of 12.8 meters long, weighing 46.2 kilograms and bearing 123 kilograms of spandex are connected to each connecting shaft only by a 4mm diameter round pin. During the working process, the load of the guide roller is relatively large, especially the guide roller near the driving shaft has the largest load. When the driving shaft of the switch car is started or stopped, the guide roller will inevitably produce a movement impact with the pin due to the inertial force. Over time, the pin will be excessively worn, cracked, and even broken, so that the guide roller stops rotating. Obviously, the key to solving the above problems is to improve the connection structure between the guide roller and the driving shaft and improve the connection strength between the two.
