Embodiment 1

[0023] like Figure 1-2 As shown, the fiber guide body in the air-jet vortex spinning device provided in this embodiment includes a base body 6 whose two ends are respectively a large end face 7 and a small end face 8, and the material of the base body 6 is copper (a metal alloy can also be used, such as steel, copper alloys, etc.). The base body 6 is a spiral body, and the side near the small end face 8 is an inclined plane 16 extending toward the axis 18 of the base body 6 . The 1 / 2 radius of the large end face 7 is twisted and cut off one side in the longitudinal direction to form a cut surface 15 that does not intersect the axis 18, that is, the shape that the axis 18 is not cut. The guide surface of the device. The cut surface 15 connects the large end surface 7 and the inclined surface 16; the base body 6 is provided with a stepped through hole 11 coaxial with the axis 18, a section of the stepped through hole 11 close to the large end surface 7 is a large diameter hol...

Embodiment 2

[0030] like Figure 4 As shown, it is a sectional view of the fiber guide in the air-jet vortex spinning device provided by this embodiment, which includes a base body 6 whose two ends are respectively a large end face 7 and a small end face 8, and the material of the base body 6 is ceramics (alumina can be used) , silicon carbide, silicon nitride, zirconia and other ceramics or any number of composite ceramics). The base body 6 is a spiral body, and the side near the small end face 8 is an inclined plane 16 extending toward the axis 18 of the base body 6 . The 1 / 2 radius of the large end face 7 is twisted and cut off one side in the longitudinal direction to form a cut surface 15 that does not intersect the axis 18, that is, the shape that the axis 18 is not cut. The guide surface of the device. The cut surface 15 connects the large end surface 7 and the inclined surface 16; the base body 6 is provided with a stepped through hole 11 coaxial with the axis 18, a section of th...

Abstract

The invention discloses a fiber guide body in an air jet vortex spinning device and a manufacturing method thereof. The fiber guide body includes a base body both ends of which are provided with a large end surface and a small end surface respectively. A cut surface is arranged on one side of the base body and connected to the large end surface and an inclined surface; stepped through holes coaxial with an axis are formed in the base body, a needle tubing is inserted into the stepped through holes, and an filling area formed between the needle tubing and a large diameter hole is filled with anadhesive. The manufacturing method comprises the steps of forming the large diameter hole in the base body along the axis from one side of the large end surface of the base body; forming a small diameter hole in the base body along the axis from one side of the small end surface of the base body, wherein the large diameter hole and the small diameter hole constitute the stepped through holes; inserting the needle tubing into the stepped through holes, and injecting the adhesive into the filling area between the large diameter hole and the needle tubing, so that the needle tubing is bonded tothe base body. The method solves the problem that fiber guide bodies in existing air jet vortex spinning devices capable of producing core-spun yarn are difficult to manufacture, so that the connection between a core wire guide pipe and a core wire guide hole is more accurate and much firmer.

Description

technical field [0001] The invention relates to a fiber guide in an air-jet vortex spinning device and a manufacturing method thereof, in particular to a fiber guide in an air-jet vortex spinning device capable of producing core-spun yarns and a manufacturing method thereof. Background technique [0002] The date of the authorized announcement is June 2, 2010, the authorized announcement number is CN 101368305 B, and the Chinese invention patent titled "A Air-jet Vortex Spinning Device Capable of Producing Core-spun Yarn" discloses a method for producing core-spun yarn air-jet vortex spinning device. Among them, a conical or cylindrical fiber and core wire guide part is provided at the entrance of the eddy current twisting tube, and a needle-shaped core wire guide tube is provided at the end of the fiber and core wire guide part, and it points to the spindle shape. The inlet end of the yarn guide tube. The fiber and core wire guiding part has a helical fiber guiding surfac...
