Description

Technical Field

[0001] The utility model relates to the technical field of textile equipment, in particular to a thread feeding roller wheel which is easy to maintain. Background Art

[0002] In the yarn supply mechanism of the textile equipment, the yarn is usually squeezed and fixed by a driving roller and a leather roller wheel, and then the yarn is drawn out from the bobbin by the rotation of the driving roller, thereby feeding the yarn to the textile equipment.

[0003] The existing leather roller wheel generally consists of a rotating mechanism composed of a bearing, a roller shaft and a sleeve. The connection method is generally to directly press the bearing into the sleeve through a stamping device, and then connect the roller shaft. Although the processing procedure is simple and the processing cost is low, after the leather roller wheel is used for a long time, the bearings of the main moving parts are often severely worn, and the invasion of waste yarn during work will also aggravate the wear of the bearing, while other parts are not seriously damaged. However, during maintenance, since the bearing is pressed into the sleeve, it is necessary to use a punch corresponding to the outer diameter of the bearing after fixing the sleeve during disassembly, and use a hammer to knock the bearing out of the sleeve several times. After replacing the bearing, it is necessary to punch the bearing back into the sleeve. Not only is the maintenance work more troublesome, but after several repairs, the sleeve will also be scrapped due to severe wear of the inner wall, and there is room for further improvement.
