DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] In the embodiment, see Figures 1 to 3 .

[0026] like Figure 1 As shown, the utility model provides a device for preventing the yarn tail from being attached to the yarn bobbin, which is installed on a rotating shaft 3 passing through a spinning frame 1. The rotating shaft 3 is used to install a yarn bobbin body 2 through a fixing screw. The device includes a blade mounting seat 4 arranged on the rotating shaft 3 and a blade structure 6 arranged on the blade mounting seat 4. The blade structure 6 is aligned with the yarn bobbin body 2 to cut off the tail yarn on the yarn bobbin body 2.

[0027] In a specific implementation, a blade structure 6 is arranged on the rotating shaft 3 through the blade mounting seat 4 and is aligned with the yarn tube body 2. When the yarn reaches a predetermined length and is about to become a tail yarn, this part of the yarn can be automatically cut off or blocked to prevent it from being thrown into the tube yarn due to the centrifugal force, thereby controlling the tail yarn outside the tube yarn to avoid interfering with the yarn body structure.

[0028] It should be noted that the blade mounting seat 4 is connected to the spinning frame 1 through a positioning bolt 5. At this time, the positioning bolt 5 cooperates with the rotating shaft 3 to limit the posture position of the blade mounting seat 4. Therefore, in actual use, it can ensure that the blade structure 6 is stably aligned with the high-speed rotating yarn tube body 2 to perform cutting or blocking operations on the tail yarn.

[0029] Further, such as Figure 2 and Figure 3 As shown, the blade structure 6 includes a blade holder 62 arranged on the blade mounting seat 4 and a blade head 61 arranged on the blade holder 62 . The blade head 61 is aligned with the yarn bobbin body 2 to cut off the tail yarn on the yarn bobbin body 2 .

[0030] The blade head 61 is generally integrated with the blade holder 62 , and its sharp section is always aligned with the bobbin body 2 .

[0031] In a specific embodiment, if Figure 2 As shown, a threaded rod 43 is threadedly provided on the blade mounting seat 4, and a twist block 44 is provided at one end of the threaded rod 43 for manually driving the threaded rod 43 to rotate. When the threaded rod 43 rotates, the twist block 44 can be moved closer to or away from the blade mounting seat 4;

[0032] It should be noted that at this time, the threaded rod 43 moves through the blade holder 62, so when the threaded rod 43 rotates and drives the twist block 44 to move closer to or away from the blade mounting seat 4, the twist block 44 can cooperate with the blade mounting seat 4 to clamp and fix the blade holder 62.

[0033] It should also be noted that at this time, through the rotation of the threaded rod 43, when the torsion block 44 moves away from the blade mounting seat 4 until the threaded rod 43 is separated from the blade mounting seat 4, the blade holder 62 can be disassembled from the blade mounting seat 4.

[0034] In a specific embodiment, reference Figure 2 and Figure 3 A positioning block 41 is also provided on the blade mounting seat 4, and the blade structure 6 also includes a positioning hole 63 provided on the blade holder 62. When the threaded rod 43 is rotated to install the blade holder 62 on the blade mounting seat 4, the positioning block 41 can cooperate to pass through the positioning hole 63. At this time, combined with the threaded rod 43, the limiting posture positioning operation of the blade holder 62 can be performed.

[0035] Furthermore, a limiting groove 42 can be provided on the blade mounting seat 4, and the positioning block 41 can slide within the limiting groove 42 to facilitate adjustment of the position of the positioning block 41 when the blade holder 62 is installed on the blade mounting seat 4, so that it is aligned and inserted into the positioning hole 63.

[0036] It should also be noted at this point that a corresponding control structure can be added to the blade mounting seat 4 to adjust the control positioning block 41 to move in the limiting slide groove 42. Generally speaking, the control structure can adopt the belt gear transmission structure, gear rack transmission structure or other transmission structure capable of controlling linear movement in the prior art, and under the condition of using the prior art to realize the movement control of the positioning block 41 in the limiting slide groove 42, a fixed structure (latches, springs and other prior art structures) is also required to ensure that the positioning block 41 will not move easily in the limiting slide groove 42.

[0037] In a specific embodiment, reference Figure 2 and Figure 3 A vertically extending mounting movable groove 64 is formed on the side wall of the blade holder 62 . The mounting movable groove 64 extends to the middle of the blade holder 62 to accommodate the threaded rod 43 .

[0038] In a specific implementation, when the threaded rod 43 rotates to a certain extent (not separated from the blade mounting seat 4), the positioning block 41 leaves the positioning hole 63. At this time, it is only necessary to move the blade holder 62 to make the threaded rod 43 leave the mounting movable groove 64 to complete the disassembly and separation operation of the blade holder 62 on the blade mounting seat 4. Similarly, by setting the mounting movable groove 64 and the positioning hole 63 on the blade holder 62, the threaded rod 43 is rotated to control the twist block 44 to approach the blade mounting seat 4 to clamp the blade holder 62, and the positioning block 41 passes through the positioning hole 63, so that the blade holder 62 can be quickly positioned, installed and tightened on the blade mounting seat 4. In summary, it is convenient to quickly assemble and disassemble blade structures 6 of different specifications on the blade mounting seat 4, and at the same time, it can be convenient to quickly replace and use the blade structure 6 after it is worn.

[0039] At this time, it can be further defined that a limited movable groove 46 is opened inside the blade mounting seat 4, and a limited round block 45 for moving in the limited movable groove 46 is provided at the other end of the threaded rod 43, which can prevent the threaded rod 43 part from being separated from the blade mounting seat 4 and being inconvenient to be realigned and installed on the blade mounting seat 4.

[0040] In summary, the device can automatically remove the tail yarn when the spinning machine is running, reducing the reliance on manual monitoring and manual removal of the tail yarn, improving production efficiency, while reducing the workload and potential safety risks of operators, and at the same time, by effectively controlling the processing of the tail yarn, improving the structural uniformity and surface smoothness of the bobbin yarn, reducing the breakage rate in subsequent processing, thereby improving the overall physical quality and stability of the weaving process.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

[0042] In addition, it should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0043] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing in the full text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or schemes that A and B meet at the same time. In addition, in the embodiments of the utility model, "multiple" refers to more than two. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.
