Before weaving, a textile yarn rack can be used to adjust parameters such as the thickness, strength, and twist of the yarn to meet the requirements of different fabrics. Specifically, when in use, a yarn spindle wound with yarn is sleeved on the core of the textile yarn rack. A spring piece is installed on the core for positioning the yarn spindle. The yarn is pulled to drive the core to rotate by the yarn spindle, and then special equipment can be used to adjust the thickness and strength of the yarn. The spring piece on the core is the yarn spindle positioning assembly for fabric production.
[0003] When the common yarn spindle positioning assembly for fabric production is in use, the positioning between the core and the yarn spindle is achieved by using a spring piece. However, when only using the elasticity of the spring piece itself to position the yarn spindle, as the use time increases, the elasticity of the spring piece itself gradually decreases. At this time, it is difficult to achieve stable positioning of the yarn spindle only through the spring piece, and the positioning stability and reliability of the yarn spindle need to be improved. Therefore, this application provides a yarn spindle positioning assembly for fabric production to meet the requirements. Summary of the Utility Model

[0029] As Figures 1-4 shown, an embodiment of the present utility model provides a spindle positioning assembly for fabric production, including a barrel core 1, and further including:
[0030] The positioning mechanism 2, the positioning mechanism 2 includes an annular cavity 21 and a cavity 24 opened inside the core 1, the annular cavity 21 and the cavity 24 are connected and communicated, as Figure 4 shown, in the same plane, the number of cavities 24 is four, and the four cavities 24 are annularly arrayed with the center of the core 1 as the array center. A pressing ring 22 is slidably connected in the annular cavity 21. Sealing rings can be embedded on both the outer wall and the inner wall of the pressing ring 22. The sealing rings are used to prevent hydraulic oil from flowing out of the gap between the pressing ring 22 and the annular cavity 21. An annular groove 5 is opened at the end of the core 1, and the annular groove 5 is connected and communicated with the annular cavity 21. The central axis of the annular groove 5 coincides with the central axis of the core 1. A pressing cylinder 29 is slidably connected to the inner wall of the annular groove 5. One side of the pressing ring 22 is fixed with a first spring 23, and the other side is attached to the end of the pressing cylinder 29. The end of the first spring 23 away from the pressing ring 22 is fixed in the annular cavity 21, and the end of the first spring 23 away from the pressing ring 22 is fixedly connected to the side of the inner wall of the annular cavity 21 away from the pressing cylinder 29. A piston 25 is slidably connected to the inner wall of the cavity 24. The number and position of the pistons 25 correspond to the number and position of the cavities 24. Hydraulic oil is filled between the piston 25 and the pressing ring 22. On the side of the piston 25 away from the annular cavity 21, a second spring 26 and a resisting rod 27 are respectively fixed. The end of the second spring 26 is fixedly connected to the inner wall of the cavity 24, and the end of the second spring 26 away from the piston 25 is fixedly connected to the side of the inner wall of the cavity 24 away from the annular cavity 21. A through hole is opened on the surface of the core 1, and the inner wall of the through hole is slidably connected to the circumferential surface of the resisting rod 27. A magnetic attraction assembly 3 is arranged on the circumferential surface of the pressing cylinder 29. When the yarn bobbin is sleeved on the core 1 and the pressing cylinder 29 is magnetically attracted and positioned by the magnetic attraction assembly 3, the pressing cylinder 29 drives the pressing ring 21 to squeeze the hydraulic oil, so that the hydraulic oil squeezes the piston 25 and makes the piston 25 move, and the piston 25 drives the resisting rod 27 to extend out of the through hole to realize the positioning of the yarn bobbin.
[0031] As Figure 3 shown, in this embodiment, the central axis of the annular cavity 21 coincides with the central axis of the core 1. Hydraulic oil is stored in the annular cavity 21. When the pressing ring 22 moves, the hydraulic oil in the annular cavity 21 is squeezed into the cavity 24 and the piston 25 moves, and the piston 25 drives the resisting rod 27 to extend out of the through hole to realize the positioning of the yarn bobbin.
[0032] As Figure 3 shown, in this embodiment, the inner wall of the annular groove 5 is provided with an inclined guiding surface, which facilitates the insertion of the pressing cylinder 29 into the annular groove 5 through this guiding surface.
[0033] As Figure 3 and Figure 4 shown, in this embodiment, a rubber block 28 is fixed to the end of the resisting rod 27. The rubber block 28 is located in the through hole. The rubber block 28 is used to increase the friction between the resisting rod 27 and the inner wall of the yarn bobbin, so as to make the positioning of the yarn bobbin more stable and reliable.
[0034] As Figure 3 shown, in this embodiment, a handle 4 is fixed to the end of the pressing cylinder 29, and the pressing cylinder 29 can be conveniently moved through the handle 4.
[0035] As Figure 3 shown, in this embodiment, the length of the handle 4 is greater than the diameter of the bobbin core 1. After the spindle is sleeved on the bobbin core 1, the handle 4 abuts against the end of the spindle. The handle can also prevent the spindle from axially moving on the bobbin core 1, making the connection between the spindle and the bobbin core 1 more stable and reliable.
[0036] As Figure 2 and Figure 3 shown, in this embodiment, the magnetic attraction assembly 3 includes a strong magnetic ring 31 fixedly sleeved on the circumferential surface of the pressing cylinder 29. A metal block 32 is inlaid at the end of the bobbin core 1. The strong magnetic ring 31 is adsorbed on the side surface of the metal block 32 by its own magnetic force. After the pressing cylinder 29 is inserted into the annular groove 5, the strong magnetic ring 31 is adsorbed on the metal block 32 by its own magnetic force, and the positioning of the pressing cylinder 29 can be realized.
[0037] As Figure 2 shown, in this embodiment, the number of the metal blocks 32 is four. The four metal blocks 32 are annularly arranged with the center of the circle of the bobbin core 1 as the array center. The strong magnetic ring 31 is adsorbed on the four metal blocks 32 at the same time, making the magnetic attraction positioning of the strong magnetic ring 31 on the pressing cylinder 29 more stable and reliable.
[0038] Working principle: Sleeve the spindle on the bobbin core 1, hold the handle 4 and insert the pressing cylinder 29 into the annular groove 5 so that the strong magnetic ring 31 is magnetically adsorbed on the metal block 32. The positioning of the pressing cylinder 29 is realized by magnetic attraction. When the pressing cylinder 29 is inserted into the annular groove 5, it drives the extrusion ring 22 to move along the inner wall of the annular cavity 21 while squeezing the first spring 23 and the hydraulic oil. The extrusion ring 22 squeezes the hydraulic oil into the cavity 24, causing the piston 25 to move in the cavity 24 and squeeze the second spring 26. The piston 25 drives the rubber block 28 to closely fit with the inner wall of the spindle through the abutting rod 27, realizing the stable and reliable positioning of the spindle;
[0039] When the spindle needs to be removed from the bobbin core 1, hold the handle 4 and pull out the pressing cylinder 29 from the annular groove 5. The pressing cylinder 29 drives the strong magnetic ring 31 to separate from the metal block 32. At the same time, the pressing cylinder 29 separates from the extrusion ring 22. After separation, the extrusion ring 22 moves reversely along the inner wall of the annular cavity 21 under the elastic force of the first spring 23. The extrusion ring 22 no longer squeezes the hydraulic oil. The piston 25 moves reversely along the inner wall of the cavity 24 under the elastic force of the second spring 26, causing the rubber block 28 to move into the through hole, and then the spindle can be removed from the bobbin core 1.

In order to enable the public to have a thorough understanding of the present utility model, specific details have been described in detail in the above preferred embodiments of the present utility model. However, those skilled in the art can also fully understand the present utility model without the description of these details.
[0041] The above description is only a preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
