A driving member for driving rotating shafts 1 and 2 to rotate is arranged on the workbench, and an adjustment groove is provided on the workbench, and the adjustment groove is slidingly arranged in the direction toward rotating shaft 2. Rotating shaft 1 is rotatably arranged on a connecting block, and an adjusting device for adjusting the position of the connecting block is arranged on the workbench. The adjusting device includes a transmission assembly for improving the stability of the rotating shaft, and an indicating scale is arranged on the workbench along the -7 direction of sliding of the connecting block, and an indicating block is arranged on the connecting block, and the indicating block and the indicating scale are arranged correspondingly.

In the process of realizing the utility model, the inventor found that the prior art has the following problems:

[0004] In the existing false twister, when the fiber is twisted on the friction disk of the false twister, the fiber will heat up rapidly due to the effect of frictional heat generation. The high temperature will increase the thermal dynamics of the fiber, causing partial melting or degradation, and accelerate the oxidation and aging of the fiber, reducing its strength and elasticity, and shortening its service life. In addition, when the fiber at room temperature enters the false twister, it will quickly heat up due to friction, causing the fiber to become brittle and easily break during the twisting process.

[0005] Therefore, in view of the above problems, a false twister for a texturing machine for processing POY filaments is proposed. Utility Model Content

[0014] Technical effects and advantages of the utility model:

[0015] 1.

[0027] Among them: when the POY yarn enters the false twister, the working disk 4 passing through the surface of the driving shaft 2 and the driven shaft 3 twists the yarn. Then, during the twisting, the air pump 804 can pump and pressurize the cold air and then transport it to the cooling mechanism 801 through the air hose 803. Then the cooling mechanism 801 sprays the airflow through three groups of airflow nozzles 802 to the twisting area of ​​the POY yarn, so that the heated POY yarn and parts are blown by the cooling airflow, and the heat generated by the friction of the equipment and materials is quickly taken away, so as to effectively reduce the temperature during the twisting process and prevent the material from overheating and causing performance degradation or breakage.

[0028] Example 2

[0029] Based on Example 1, the solution in Example 1 is further detailed in combination with the following specific working method. Figures 1 to 5 As shown, see the following description for details:

[0030] As a preferred embodiment, a support plate 7 is provided on the left side of the upper end surface of the base 1, and a heating roller 9 is provided on the upper end of the right side of the support plate 7. The roller body of the heating roller 9 is provided with a resistance heating wire 10. Two groups of heating rollers 9 are provided, and the two groups of heating rollers 9 correspond to each other in an upper and lower parallel manner. The resistance heating wire 10 is wrapped around the inner surface of the roller body of the heating roller 9; further, the POY yarn enters the two groups of heating rollers 9 in an interlaced manner before entering the false twister, and the electrical energy is converted into thermal energy by the resistance heating wire 10 wrapped around the surface thereof, thereby evenly preheating the POY yarn.

[0031] As a preferred embodiment, the upper end of one group of driven shafts 3 is sleeved with an inlet disk 5, and the lower end of the other group of driven shafts 3 is sleeved with an outlet disk 6; further, the POY yarn can enter the working disk 4 through the inlet disk 5 for twisting, and be discharged through the outlet disk 6 after twisting is completed.

[0032] As a preferred embodiment, one end of the driving shaft 2 passes through the center of the base 1, and a plurality of working disks 4 are provided, and the plurality of working disks 4 are arranged at equal intervals; further, when the false twister is installed on the texturing machine, the texturing machine drives the driving shaft 2 to work, and the working disks 4 provide a friction effect with the POY yarn.

[0034] The working process of the utility model is as follows: the base 1 is used to be installed on the texturing machine. First, before entering the false twister, the POY yarn enters the two groups of heating rollers 9 at the upper end of the support plate 7 through an interlaced manner, and the electrical energy is converted into thermal energy through the resistance heating wire 10 surrounding the surface thereof, so as to evenly preheat the POY yarn. When the POY yarn enters the false twister, the POY yarn passes through the working disk 4 on the surface of the driving shaft 2 and the driven shaft 3 through the introduction disk 5 to twist the silk thread, and is discharged through the lead-out disk 6 after the twisting is completed. Subsequently, during the twisting, the cold air can be pumped and pressurized by the air pump 804 and then transported to the cooling mechanism 801 through the air hose 803. Subsequently, the cooling mechanism 801 sprays the airflow through the three groups of airflow nozzles 802 to the twisting area of ​​the POY yarn, so that the heated POY yarn and parts are blown by the cooling airflow, and the heat generated by the friction of the equipment and materials is quickly taken away. The above is the working principle of the false twister for the texturing machine for processing POY filaments.

[0035] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
