[0002] A yarn bobbin is a drum used for taking up and paying out yarn, and is typically mounted on a spinning machine in a rotating manner. However, existing yarn bobbins can break the yarn if continued rotation increases tension during the take-up process. During pay-out, the yarn can also break if the combined weight of the bobbin itself and the yarn is high. Consequently, existing yarn bobbin structures are subject to a certain degree of yarn breakage during industrial use, presenting certain limitations. Summary of the Invention

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] See also Figures 1-10 As an embodiment of the present invention, the detachable yarn bobbin structure includes an inner bobbin 1 and an outer bobbin structure sleeved outside the inner bobbin 1, and an anti-breaking mechanism is provided between the inner bobbin 1 and the outer bobbin structure;

[0031] The anti-breaking mechanism is used to elastically rotate and connect the outer cylinder structure and the inner cylinder 1;

[0032] The anti-breaking mechanism includes an extrusion groove 4 provided on the inner wall of the outer cylinder structure, a slider 6 provided on the inner cylinder 1 for sliding along the axial direction of the inner cylinder 1, and a spring 7 elastically connecting the slider 6 and the inner cylinder 1, and the slider 6 cooperates with the extrusion groove 4; when the outer cylinder structure rotates relative to the inner cylinder 1, the slider 6 is driven by the extrusion groove 4 to slide along the axial direction of the inner cylinder 1, and the spring 7 is further compressed.

[0033] In this embodiment, the inner tube 1 and the outer tube structure constitute a basic yarn tube structure. The inner tube 1 drives the outer tube structure to rotate through the cooperation of the slider 6 and the extrusion groove 4. When the resistance encountered during the rotation of the outer tube structure is large, the outer tube mechanism will push the slider 6 in the opposite direction through the extrusion groove 4 to slide along the axial direction of the inner tube 1. The slider 6 squeezes the spring 7 inside the inner tube 1. When the inner tube 1 continues to rotate, the outer tube structure is briefly stopped and buffered, thereby preventing the yarn from being broken.

[0034] As a further solution of the present invention, the outer cylinder structure includes a first half outer cylinder 2 and a second half outer cylinder 3 , and the first half outer cylinder 2 and the second half outer cylinder 3 are symmetrically distributed on the surface of the inner cylinder 1 .

[0035] In this embodiment, the first half outer cylinder 2 and the second half outer cylinder 3 are symmetrically distributed on the surface of the inner cylinder 1, so that the outer cylinder structure is detachable.

[0036] As a further solution of the present invention, a slide groove 5 is provided on the inner cylinder 1, and the upper portion of the slider 6 is slidably arranged inside the slide groove 5;

[0037] A triangular portion is formed at one end of the slider 6 , and a triangular recess matched with the triangular portion is also formed at one end of the extrusion groove 4 .

[0038] In this embodiment, when the outer cylinder structure reacts with the slider 6 through the extrusion groove 4 , the slider 6 slides inside the slide groove 5 .

[0039] As a further solution of the present invention, an inner through groove 8 is opened inside the inner cylinder 1, and the lower portion of the slider 6 is slidably arranged inside the inner through groove 8, and the lower cross-section of the slider 6 is adapted to the cross-section of the inner through groove 8;

[0040] The spring 7 is arranged inside the inner groove 8, one end of the spring 7 abuts against the slider 6, and the other end of the spring 7 abuts against the inner wall of the inner tube 1. A protrusion is provided on the slider 6, and the end of the spring 7 close to the slider 6 is sleeved on the surface of the protrusion.

[0041] In this embodiment, when the slider 6 slides inside the slide groove 5, it will squeeze the spring 7 through its own protrusion, so that the outer cylinder structure has a certain buffer time. When the outer cylinder structure continues to rotate, the reaction force of the extrusion groove 4 on the outer cylinder structure on the slider 6 disappears, and the spring 7 returns to its original position under the action of reset.

[0042] As a further solution of the present invention, connecting shafts 9 are provided at both ends of the first half outer cylinder 2 , and connecting blocks 10 are rotatably provided on the connecting shafts 9 .

[0043] In this embodiment, when the first half outer cylinder 2 and the second half outer cylinder 3 need to be assembled together, the first half outer cylinder 2 and the second half outer cylinder 3 are aligned and sleeved on the surface of the inner cylinder 1. At this time, the connecting blocks 10 at both ends of the first half outer cylinder 2 are first rotated around the axis of the connecting shaft 9 to the corresponding positions on the second half outer cylinder 3.

[0044] As a further solution of the present invention, thread grooves 11 are provided at both ends of the second half outer cylinder 3, and the internal threads of the thread grooves 11 are provided with studs 12, and the studs 12 cooperate with the connecting block 10 to fasten the first half outer cylinder 2 and the second half outer cylinder 3 together.

[0045] In this embodiment, thread grooves 11 are provided at both ends of the second half outer cylinder 3. When the first half outer cylinder 2 and the second half outer cylinder 3 need to be installed together, the connecting block 10 is aligned with the thread groove 11, and the stud 12 is rotated at this time, so that the stud 12 cooperates with the connecting block 10 and the thread groove 11 to connect the first half outer cylinder 2 and the second half outer cylinder 3 together. Conversely, by rotating the stud 12 in the opposite direction, the first half outer cylinder 2 and the second half outer cylinder 3 can be disassembled.

[0046] As a further solution of the present invention, a limit strip 13 is provided near the middle of the inner cylinder 1, and an annular groove 14 is provided on the inner wall of the first half outer cylinder 2 and the second half outer cylinder 3, and the length of the limit strip 13 is smaller than the annular groove 14, and the limit strip 13 is slidably arranged inside the annular groove 14.

[0047] In this embodiment, a limit strip 13 is installed on the inner cylinder 1, and an annular groove 14 is opened on the outer cylinder structure, thereby limiting the axial sliding of the outer cylinder structure on the inner cylinder 1 in the axial direction, making the yarn cylinder structure run more stably.

[0048] The above embodiments are exemplary rather than restrictive, so any technical solution of the present invention that can be implemented in other specific forms without departing from the spirit or basic features of the present invention is included in the present invention.
