[0024] The application will be further described in detail below with reference to the accompanying drawings.

[0025] In order to more clearly understand the technical solutions provided by the embodiments of the application, first, the use and replacement of the yarn breaking device in the prior art are simply introduced.

[0026] The broken yarn device of the spinning frame spindle is prone to lose its function due to wear and tear in actual use, and the service life of the broken yarn device is far lower than that of the spindle. However, the broken yarn device is generally fixed on the spindle disc by interference fit, and is difficult or impossible to replace, so the damage of the broken yarn device often leads to the replacement of the entire spindle, greatly increasing the cost of the spinning enterprise.

[0027] To solve the above problems, Chinese patent CN105200586A discloses a spinning spindle with replaceable broken yarn device, which comprises an aluminum rod, a spindle disc, an elastic collar and a broken yarn device. One end of the aluminum rod is pressed into the spindle disc. The broken yarn device comprises a blade holder and a blade. The blade holder is sleeve-shaped, and an annular groove is arranged in the inner hole thereof. One end of the blade holder is provided with a radial protruding part in the form of a ring. The end face of the protruding part close to the middle part of the blade holder is provided with a plurality of axial blade holder teeth. The blade is in the form of a circular ring, and is installed in the inner tangent circle of the axial blade holder teeth of the blade holder. The upper end face of the spindle disc is provided with a boss, and the circumferential direction of the boss is provided with a clamping groove. The blade holder is sleeved on the boss, and the axial blade holder teeth are directed towards the upper end face of the spindle disc. The elastic collar is clamped in the groove of the annular groove and the clamping groove. The patent has the advantage of easily replacing the broken yarn device, but the blade holder is directly sleeved on the boss, and is only axially limited by the elastic collar without radial constraint. During use, the blade holder is prone to rotate, resulting in incomplete broken yarn, which will seriously affect the production efficiency and greatly increase the labor intensity.

[0028] Chinese patent CN215947503U discloses a spinning frame aluminum rod spindle with firmly installed yarn cutter, which comprises an aluminum rod, a spindle disc, a yarn cutter and a spindle seat. The aluminum rod is vertically arranged in the middle part of the spindle disc. The yarn cutter is fixedly coupled to the top of the outer periphery of the spindle disc. The bottom of the aluminum rod is inserted into the inner cavity of the spindle seat. The top of the outer wall of the spindle disc is provided with a flange step. An annular groove is arranged on the cylindrical surface of the upper side of the flange step. The yarn cutter comprises a blade holder and a blade. The blade is installed at the bottom of the blade holder. The inner hole of the blade holder is in interference fit with the cylindrical surface of the upper part of the flange step. The top of the blade holder is provided with an outer riveting part. The material of the yarn cutter is embedded in the annular groove through the outer riveting part. The top end of the spindle disc is provided with an inner riveting part at the interface between the blade holder and the spindle disc. The material of the spindle disc is embedded in the inner part of the blade holder through the inner riveting part. The patent solves the problem of loose installation of the yarn cutter of the existing spinning frame aluminum rod spindle, but when replacing the yarn cutter, the old yarn cutter needs to be pried to separate the outer riveting part from the inner riveting part, and then the new yarn cutter needs to be riveted. Riveting requires special equipment and complex process, and will damage the surface of the workpiece, resulting in hooking of yarn during the cutting process, which will seriously affect the production efficiency and greatly increase the labor intensity.

[0029] To solve the above technical problems, with reference to the accompanying Figure 1 -Appendix Figure 6The embodiment of the application provides a spindle facilitating radial stability of a yarn cutter, which comprises a spindle rod 1, the spindle rod 1 has a first end and a second end, a lower supporting assembly 3 is inserted into the second end of the spindle rod 1, and the lower supporting assembly 3 is used for supporting the spindle rod 1 and an accessory on the spindle rod 1;

[0030] A spindle disc 2 is sleeved outside the middle part of the spindle rod 1, the relative position of the spindle disc 2 and the spindle rod 1 is fixed in a complete assembly state, the spindle disc 2 is hollow inside and has two open ends, and the two open ends of the spindle disc 2 pass through the internal space of the spindle disc 2;

[0032] The following will be further introduced in combination with a specific use scenario.

[0033] In use, the spindle rod 1 is on the lower supporting assembly 3, and the yarn cutter 23 outside the spindle disc 2 normally works;

[0034] Since the yarn cutter 23 is detachably connected to the spindle disc 2, an operator can realize mounting or dismounting of the yarn cutter 23 by tightening or loosening the thread 211 connection between the yarn cutter 23 and the mounting area 21, when the yarn cutter 23 cannot be used due to damage, wear and the like, the operator only needs to loosen the thread 211 connection between the yarn cutter 23 and the mounting area 21 to realize dismounting of the yarn cutter 23, and then the operator completes the thread 211 connection between the new yarn cutter 23 and the mounting area 21 to realize replacement of the new yarn cutter 23.

[0035] In this process, the operator does not need to dismount the entire spindle rod 1 from the lower supporting assembly 3, and does not need to replace the entire spindle rod 1, the efficiency of replacing the new yarn cutter 23 is higher, the spindle rod 1 is not wasted, the production cost of spinning is reduced, and the overall efficiency and benefit of spinning are significantly improved.

[0036] Generally, the yarn cutter 23 is detachably connected to the spindle disc 2 in the embodiment of the application, so that the yarn cutter 23 can be quickly mounted or dismounted, when the yarn cutter 23 cannot be used due to damage, wear and the like, the operator can make production proceed normally by quickly replacing the yarn cutter 23, without additional replacement of the spindle rod 1, the production cost of spinning is reduced, and the overall efficiency and benefit of spinning are significantly improved.

[0037] The flyer 2 is sleeved outside the spindle 1, and in the assembled state, the relative position of the flyer 2 and the spindle 1 is fixed. In one possible implementation of the embodiment, the flyer 2 is in interference fit with the spindle 1, and the relative position of the flyer 2 and the spindle 1 is fixed through the interference fit.

[0038] As one possible implementation of the embodiment, the cutter 23 installed in the installation area 21 of the flyer 2 is restrained from axially moving towards the first end and the second end of the spindle 1 when working.

[0039] In some possible implementations of the embodiment, the flyer 2 is provided with a blocking portion 25 for blocking the axial translation of the cutter 23, the blocking portion 25 is located on the side of the installation area 21 close to the second end of the spindle 1, the outer diameter of the blocking portion 25 is greater than the inner diameter of the cutter 23 and the outer diameter of the installation area 21, and after the cutter 23 is installed in the installation area 21, the axial displacement of the cutter 23 towards the second end of the spindle 1 is restrained by the blocking portion 25.

[0040] In some possible implementations of the embodiment, an annular groove 212 is formed on the outer side of the end of the installation area 21 away from the blocking portion 25, that is, on the outer side of the end of the installation area 21 close to the first end of the spindle 1, and a shaft stop ring 22 is detachably connected inside the annular groove 212, the cutter 23 is located between the shaft stop ring 22 and the blocking portion 25, the outer diameter of the shaft stop ring 22 is greater than the inner diameter of the cutter 23 when the shaft stop ring 22 is installed in the annular groove 212, and after the cutter 23 is installed in the installation area 21, the axial displacement of the cutter 23 towards the first end of the spindle 1 is restrained by the blocking portion 25.

[0041] The shaft stop ring 22 is used to restrain the axial movement of the cutter 23. In one possible implementation of the embodiment, the shaft stop ring 22 is made of an elastic strip, which can be made of a metal with elasticity. The two ends of the elastic strip are close to each other to form the annular shaft stop ring 22. In this way, when the cutter 23 is disassembled and assembled, the operator only needs to stretch the shaft stop ring 22 at both ends to make the opening of the shaft stop ring 22 larger, and then remove the shaft stop ring 22 from the annular groove 212. The efficiency of replacing the new cutter 23 is higher.

[0042] In one possible implementation of the embodiment, the two ends of the shaft stop ring 22 are provided with through holes.
