[0018] Next, the substantial features and advantages of the present utility model will be further described in conjunction with examples, but the present utility model is not limited to the listed embodiments.

[0019] Such as Figures 1 to 5As shown in the figure, a wire guiding device of a knitting machine according to this embodiment includes a mounting base 1 and a rotating part 2. The rotating part 2 is arranged on the mounting base 1 and can rotate relative to the mounting base 1. The silk thread 10 is guided by the rotating part 2. An end face of the mounting base 1 is provided with a circuit board 20. The circuit board 20 is annular and arranged around a central through hole 11 of the mounting base 1, so as to facilitate the installation of the circuit board. The circuit board 20 is provided with a sensor 31. A lead wire 32 of the circuit board 20 is passed through a cavity 12 of the mounting base 1, so that the lead wire of the circuit board 20 can be conveniently led out from the other end of the mounting base 1. A shaft rod 3 is passed through the through hole 11 of the mounting base 1. The rotating part 2 is sleeved on the shaft rod 3 and rotates relative to the shaft rod 3. The rotating part 2 is provided with a receiving cavity 22. An induction part 4 is arranged in the receiving cavity 22. The induction part 4 rotates synchronously with the rotating part 2. The induction part 4 and the sensor 31 are arranged opposite to each other, so that the sensor 31 can sense the rotation of the induction part 4. A wire groove 21 is arranged on an outer peripheral surface of the rotating part 2. A baffle 5 is arranged outside the rotating part 2. The baffle 5 and the mounting base 1 are connected by a locking part 6, so as to prevent the silk thread from coming out of the wire groove 21. The locking part 6 is a bolt. In the above technical solution, the silk thread 10 is wound in the wire groove 21. The sliding of the silk thread 10 drives the rotating part 2 to rotate, so that the induction part 4 rotates synchronously. When the induction part 4 passes through the position of the sensor 31, the sensor 31 senses a signal, so that the number of rotation turns of the rotating part 2 can be calculated. Through the contact length between the silk thread 10 and the wire groove 21, the length of the silk thread passing through can be calculated through a controller and then displayed on a display panel of the device, which is convenient for the user to judge. The sensor in this embodiment is a Hall sensor. Through the above technical solution, the length of the silk thread passing through the wire guiding device can be obtained. At the same time, the sensor is located between the mounting base and the rotating part, is not easily damaged, and is convenient for disassembly and assembly.

[0020] In this embodiment, the mounting base 1 is provided with a radial hole 13. The radial hole 13 is communicated with the through hole 11. A positioning part 30 is arranged in the radial hole 13. The positioning part 30 is locked into the radial hole 13 to press the shaft rod 3, which is convenient for fixing the shaft rod 3. The positioning part 30 in this embodiment is a bolt. A bearing 6 is arranged on the shaft rod 3. The rotating part 2 is sleeved on the bearing 6, so that the bearing 6 can rotate flexibly. An end cover 7 is arranged outside the bearing 6. The end cover 7 is arranged in a central mounting hole 22 of the rotating part 2 to seal the bearing and prevent pollutants from entering the bearing and affecting the rotation. A sealing gasket 8 is arranged in the mounting hole 22. The end cover 7 abuts against the sealing gasket 8, so as to further improve the sealing performance of the mounting hole 22. A convex part 71 is arranged on one side of the end cover 7. The sealing gasket 8 is provided with an annular groove 81. The convex part 71 and the annular groove 81 are arranged corresponding to each other, so as to support the sealing gasket 8 through the convex part 71, prevent the sealing gasket 8 from losing elasticity and shrinking after long-term use, resulting in sealing failure, and extend the service life of the sealing gasket 8. There are two convex parts in this embodiment. One end of the mounting base 1 is provided with a cover plate 9. The cover plate 9 seals the cavity 12 of the mounting base 1, so that both ends of the mounting base 1 can be sealed.

[0021] The wire guiding device of a knitting machine according to this embodiment can obtain the length of the wire passing through the wire guiding device. At the same time, the sensor is located between the mounting seat and the rotating part, is not easily damaged, and is convenient for disassembly and assembly.
