Detailed Description
The drawings in the embodiments of the present invention will be combined; the technical scheme in the embodiment of the utility model is clearly and completely described; obviously; the described embodiments are only some of the embodiments of the present invention; but not all embodiments, are based on the embodiments of the invention; all other embodiments obtained by a person skilled in the art without making any inventive step; all belong to the protection scope of the utility model.
As shown in fig. 1-2, a chenille machine textile bobbin is suitable for a high-speed (digital) chenille machine, which comprises a connecting pipe 1, a first flange 2 and a second flange 3 which are respectively positioned at two connecting ends, wherein the connecting pipe 1, the first flange 2 and the second flange 3 are made of aluminum alloy, the inner holes of the connecting pipe 1, the first flange 2 and the second flange 3 are firstly subjected to finish machining, then the connecting pipe 1, the first flange 2 and the second flange 3 are fixed through friction welding, and the outer surface is processed after welding, so that the outer surface is provided with a plurality of annular threads. The first flange 2 of after-treatment and the connecting position surface of connecting pipe 1 are smooth and are first fillet 11, and the radius of first fillet 11 is 1.2mm moreover, and the 11 radiuses of little first fillet can increase connecting pipe 1 at axial utilization ratio, increase the volume of holding the yarn of bobbin.
