[0013] The present utility model will be specifically described below with reference to the drawings:

[0014] As shown in Figure 1 and Figure 2, a twister mandrel for textile machinery according to the present utility model includes a yarn guiding mandrel 1, and a guiding hole 2 is horizontally opened in the middle part inside the yarn guiding mandrel 1; an installation groove 3 is opened in the middle right side inside the yarn guiding mandrel 1, and the installation groove 3 communicates with the guiding hole 2.

[0015] Among them, a twister mandrel for textile machinery further includes an air-blowing assisted threading assembly 4, and the air-blowing assisted threading assembly 4 is inserted into the installation groove 3; the air-blowing assisted threading assembly 4 is detachably and fixedly connected to the right end of the yarn guiding mandrel 1, which is beneficial to achieving the effect of blowing-assisted threading, thereby facilitating the passing of the yarn through the mandrel, making it more convenient to use, and further avoiding the problem that the production efficiency of the yarn is affected.

[0016] In this embodiment, as shown in the attached Figure 3 figure, the air-blowing assisted threading assembly 4 includes an assisted threading tube 41, and an annular baffle 42 is integrally connected to the outer wall of the assisted threading tube 41; an air distribution chamber 43 is opened in the right side inside the assisted threading tube 41; air blowing holes 44 are respectively opened in the peripheral parts inside the assisted threading tube 41, and the right sides of the air blowing holes 44 communicate with the air distribution chamber 43 respectively; the left sides of the air blowing holes 44 are all inclined upward; an air inlet pipe 45 is integrally connected to the opening at the lower right side of the assisted threading tube 41, and the air inlet pipe 45 communicates with the air distribution chamber 43, wherein the air inlet pipe 45 is located on the right side of the annular baffle 42.

[0017] In this embodiment, specifically, the left end of the assisted threading tube 41 is inserted into the installation groove 3.

[0018] In this embodiment, specifically, the left part of the annular baffle 42 is detachably and fixedly connected to the right end of the yarn guiding mandrel 1.

[0019] In this embodiment, specifically, the inner diameter of the auxiliary wire threading tube 41 is equal to the inner diameter of the guiding hole 2.

[0020] In this embodiment, specifically, the auxiliary wire threading tube 41 is made of a stainless steel tube with a circular longitudinal section.

[0021] In this embodiment, specifically, the air distribution chamber 43 is an annular chamber.

[0022] In this embodiment, specifically, the lower end of the air inlet pipe 45 is connected to the output end of an external air compressor through a pipeline.

[0023] In this embodiment, when threading the wire, the operator can first turn on the external air compressor, so that the air compressor fills the inside of the air distribution chamber 43 with air through the pipeline and the air inlet pipe 45. Subsequently, the air will enter the inside of the auxiliary wire threading tube 41 through the air blowing holes 44. Then the air will enter the guiding hole 2. Since the left side of the air blowing holes 44 is inclined upward, the air will flow from right to left. Subsequently, the operator can insert the yarn from the right end of the auxiliary wire threading tube 41. When the end of the yarn passes through the output end of the air blowing holes 44, the air will blow the yarn, so that the yarn can be in a vertical state, effectively avoiding the problem that the yarn bends after entering the inside of the guiding hole 2. At this time, the operator can continue to feed the yarn into the auxiliary wire threading tube 41 until the end of the yarn moves out from the left end of the yarn guiding mandrel 1. Since the present utility model can blow the yarn with air and effectively prevent the yarn from bending, the operator can easily pass the yarn through the yarn guiding mandrel 1, achieving the effect of blowing air-assisted wire threading, which is more convenient to use, and further avoiding the problem that the production efficiency of the yarn is affected.

[0024] Any technical solution using the technical solution of the present utility model, or designed by those skilled in the art under the inspiration of the technical solution of the present utility model to achieve the above technical effects, shall fall within the protection scope of the present utility model.
