The power source of the lifting motion of the magnetic ring 140 is the lifting component 160 and the magnetic component 150, and the power source of the rotating motion of the magnetic ring 140 is the outer cover 130, so that the problem of easy abrasion caused by twisting of the ring spindle through the steel wire ring at present is effectively solved, and the abrasion between the yarn and the magnetic ring 140 is reduced. Thus, the yarns are twisted through the magnetic ring 140, the frequent replacement of the magnetic ring 140 is not needed, the yield of the ring spinner 100 can be ensured, the workload of operators is reduced, and the spinning efficiency is improved.

In one embodiment, the yarn guide hook 143 is located on the inner wall of the magnetic ring 140. The yarn guide hook 143 is used for hooking the yarn. Moreover, the radial length of the yarn guide hook 143 along the inner wall of the magnetic ring 140 is smaller than the distance between the magnetic ring 140 and the spindle 120, so that the interference between the yarn guide hook 143 and the sleeve 133 of the spindle 120 can be avoided, the stable rotation of the magnetic ring 140 is ensured, and meanwhile, the abrasion of the magnetic ring 140 can be reduced.

After the matching part 141 is matched with the limiting part 131, the position of the matching part 141 can be limited, so that the magnetic ring 140 can synchronously rotate along with the outer cover 130, and the transmission of the position of the magnetic ring 140 is avoided.

Specifically, when the outer cover 130 rotates, the outer cover 130 drives the limiting portion 131 thereon to rotate synchronously, and meanwhile, due to the matching between the limiting portion 131 and the matching portion 141, the limiting portion 131 drives the matching portion 141 to rotate synchronously, and further the matching portion 141 drives the magnetic ring 140 to rotate synchronously, so that the outer cover 130 drives the magnetic ring 140 to rotate around the spindle 120. Moreover, when the lifting assembly 160 drives the magnetic ring 140 to lift through the magnetic assembly 150, the magnetic ring 140 can move up and down along the limiting portion 131 through the matching portion 141, so as to ensure the accurate movement position of the magnetic ring 140.

Illustratively, as shown in fig. 2, the position-limiting portion 131 is a position-limiting groove, and the mating portion 141 is a position-limiting protrusion.

Meanwhile, the lifting assembly 160 drives the magnetic ring 140 to move up and down along the limiting portion 131 by the matching portion 141 of the magnetic ring 140 through the magnetic assembly 150, so that the magnetic ring 140 can wind the yarn around the bobbin 121 of the spindle 120.

Alternatively, the magnetic ring 140 may include only the magnetic ring 142. Of course, in the embodiment, the magnetic ring 140 may further include a bracket 144 in addition to the magnetic ring 142. The magnetic ring 142 may be connected to the inner wall of the housing 130 by a bracket 144. At this time, the engaging portion 141 is provided on the outer periphery of the bracket 144. Alternatively, the magnetic ring 142 is fixed to the bracket 144 by means of gluing, connecting members, or the like; of course, the magnetic ring 142 and the bracket 144 can be an integral structure. Of course, in another embodiment of the present invention, when the magnetic ring 140 includes only the magnetic ring body 142, the limiting portion 131 is directly disposed on the periphery of the magnetic ring 140.

In an embodiment, the number of the first limiting protrusions and the number of the second limiting protrusions are at least two, the first limiting protrusions are distributed on the inner wall of the outer cover 130 at intervals, the second limiting protrusions are distributed on the periphery of the magnetic ring 140 at intervals, and each first limiting protrusion is abutted against the corresponding second limiting protrusion to drive the magnetic ring 140 to rotate. That is to say, the number of the first limiting protrusions is multiple, the number of the second limiting protrusions is multiple, and the outer cover 130 drives the magnetic ring 140 to rotate synchronously by matching the first limiting protrusions and the second limiting protrusions, so that the magnetic ring 140 moves up and down along the outer cover 130.

Optionally, the number of the first limiting bulges and the number of the second limiting bulges are two, the two first limiting bulges are uniformly distributed, and the two second limiting bulges are uniformly distributed. That is to say, the two first limiting protrusions are oppositely disposed on the inner wall of the outer cover 130, the phase difference between the two first limiting protrusions is 180 °, and meanwhile, the two second limiting protrusions are oppositely disposed on the outer wall of the magnetic ring 140, and the phase difference between the two second limiting protrusions is 180 °. Thus, the uniform stress of the magnetic ring 140 can be ensured, and the twisting effect can be ensured.

The second limiting bulges are positioned between the adjacent first limiting bulges. That is, the two first limiting protrusions form a limiting groove, and the second limiting protrusion is located in the limiting groove. Like this, two first spacing bellied outer walls can with the spacing bellied outer wall butt of second, guarantee that the spacing bellied position of second is accurate, can not take place the transmission, and then guarantee that dustcoat 130 reliably drives magnetic ring 140 and rotate, guarantee the twisting effect.

In one embodiment, the lifting assembly 160 includes a driving motor 161, a screw 162 connected to the driving motor 161, and a nut 163 sleeved on the screw 162, the nut 163 is connected to the magnetic assembly 150, the driving motor 161 drives the screw 162 to rotate, and drives the nut 163 to move up and down along the screw 162, so as to drive the magnetic assembly 150 to move up and down synchronously. When the ring spinning machine 100 is operated, the driving motor 161 rotates forward or reversely, the screw 162 rotates forward or backward to make the screw 163 move up and down along the screw 162, and the screw 163 drives the magnetic assembly 150 to move up and down synchronously. At this time, the magnetic assembly 150 can drive the magnetic ring 140 in the outer cover 130 to synchronously lift, so that the magnetic ring 140 winds the yarn around the sleeve 133 of the spindle 120.

In other embodiments of the present invention, the lifting assembly 160 is a telescopic rod assembly. The telescopic rod component can do telescopic motion. When the telescopic rod component extends out, the magnetic component 150 can be driven to ascend, and when the telescopic rod component retracts, the magnetic component 150 can be driven to descend, so that the magnetic component 150 can also be lifted, and the magnetic component 150 can drive the magnetic ring 140 to lift. It can be understood that the telescopic rod assembly can be an electromagnet or an air cylinder and the like. Of course, the lifting assembly 160 may also have other configurations that allow for lifting movement.

It is understood that the magnetic assembly 150 may suspend the magnetic ring 140 in the housing 130 by an attractive force or a repulsive force, and be driven to rotate by the housing 130. The specific situation is as follows:

in one embodiment, the magnetic assembly 150 includes an absorption ring, and the absorption ring generates an absorption force for absorbing the magnetic ring 140. Therefore, the magnetic ring 140 can be close to the outer cover 130, and the outer cover 130 drives the magnetic ring 140 to rotate synchronously.

Thus, when the lifting assembly 160 drives the first magnetic element 151 and the second magnetic element 152 to ascend or descend synchronously, the first magnetic element 151 and the second magnetic element 152 will follow the synchronous ascending or descending of the magnetic ring 140.
