Description

Technical Field

[0001] This utility model relates to the field of textile yarn guiding technology, specifically a precision yarn guiding structure for linen and cotton yarn with a yarn blocking boss assembly. Background Technology

[0002] The main structure of the linen and cotton yarn guiding structure consists of a guide wheel and a bearing. The guide wheel guides and supports the movement of the yarn. However, the bearing will wobble slightly during use, which will also cause the guide wheel connected to the outer ring of the bearing to wobble. This makes it difficult for the yarn to stay in the center position, thus making it impossible to precisely guide the linen and cotton yarn.

[0003] To address the aforementioned technical issues, patent document CN202323102741.4, entitled "A Textile Guide Roller," was found. This design places the right side of the guide roller firmly against a ball bearing disc, while the left side is held in place by multiple rotating balls. This allows the guide roller to rotate only axially, preventing it from wobbling and significantly reducing the possibility of wobbling. However, this solution only prevents the guide roller from axially wobbling following the bearing, not radially. Furthermore, the guide roller often needs replacement due to wear. Before removing the guide roller from the bearing, the rotating ball structure on the left side must be removed, requiring repeated disassembly and reassembly of the left-side rotating ball structure each time the roller is replaced, which is laborious and time-consuming. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a precision yarn guiding structure for linen and cotton yarn with a yarn-blocking boss assembly, thus solving the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a precision yarn guiding structure for linen and cotton yarn with a yarn-blocking boss assembly, including a yarn guiding wheel and a bearing;

[0006] The guide wheel includes a wheel body assembly and a yarn-blocking boss assembly connected to both sides of the wheel body assembly. The wheel body assembly is detachably connected to the outer ring of the bearing, and the inner ring of the bearing is detachably connected to the support shaft.

[0007] A connecting rod is evenly and circumferentially arranged on the right side of the outer ring of the bearing, and ball bearing one, ball bearing two and ball bearing three are movably connected to the connecting rod.

[0008] Among them, the right side of the first ball is in contact with the fixed plate mounted on the support shaft, the second ball is in contact with the radial guide assembly, and the left side of the third ball is in contact with the axial guide assembly.

[0009] Preferably, the radial guide assembly includes a semi-circular plate that contacts the ball bearing two. Two semi-circular plates are provided, with the upper and lower semi-circular plates in contact with each other.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] See Figures 1-4 This utility model provides the following two technical solutions:

[0024] First implementation: A precision yarn guiding structure for linen and cotton yarn with a yarn blocking boss assembly, including a yarn guiding wheel and a bearing 3;

[0025] The guide wheel includes a wheel body assembly 1 and a yarn-blocking boss assembly 2 connected to both sides of the wheel body assembly 1. The wheel body assembly 1 is detachably connected to the outer ring of the bearing 3, and the inner ring of the bearing 3 is detachably connected to the support shaft 4.

[0026] A connecting rod 7 is evenly arranged circumferentially on the right side of the outer ring of bearing 3. A ball 8, a ball 9 and a ball 10 are movably connected to the connecting rod 7.

[0027] In this design, the right side of ball 8 contacts the fixed plate 5 mounted on the support shaft 4, ball 9 contacts the radial guide assembly, and the left side of ball 10 contacts the axial guide assembly. The fixed plate 5 and the axial guide assembly position ball 8 and ball 10 respectively, preventing axial wobble of the outer ring of bearing 3. The radial guide assembly positions ball 9, preventing radial wobble of the outer ring of bearing 3. This ensures that the guide wheel does not wobble axially or radially during use, guaranteeing precise yarn guiding of linen and cotton yarns. Furthermore, the connecting rod 7, ball 8, ball 9, ball 10, fixed plate 5, axial guide assembly, and radial guide assembly are all located on the right side of the guide wheel. Therefore, compared with existing technologies, the disassembly and assembly steps can be reduced when replacing the guide wheel; it can simply be removed from bearing 3.

[0028] The radial guide assembly includes a semi-circular plate 11 that contacts the ball bearing 9. There are two semi-circular plates 11, with the upper and lower semi-circular plates 11 in contact with each other. The semi-circular plates 11 are provided with mounting rings 12 that contact the fixing plate 5. The mounting rings 12 are provided with bolts 14 that connect to the fixing plate 5. First, the bottom semi-circular plate 11 is installed by bolts 14. Then, the top semi-circular plate 11 is placed on the bottom semi-circular plate 11. Finally, bolts 14 are tightened. This allows the ball bearing 9 to roll within the upper and lower semi-circular plates 11 when it rotates with the connecting rod 7, and it cannot move radially.

[0029] Both ends of the semicircular plate 11 are provided with protruding plates 13, and the bottom of the top protruding plate 13 is provided with a positioning block. The bottom protruding plate 13 is provided with a concave hole 15 that matches the positioning block, so that when assembling the upper semicircular plate 11, the upper semicircular plate 11 can be positioned by inserting the positioning block into the concave hole 15.

[0030] The axial guide assembly includes a semicircular ring 16 that contacts the left side of the semicircular plate 11. There are two semicircular rings 16, with the upper and lower semicircular rings 16 in contact with each other. The semicircular rings 16 also contact the left side of the ball bearing 10. Both ends of the semicircular ring 16 are provided with protrusions 17. Bolts 18 that connect to the protruding plate 13 are provided on the protrusions 17. After the semicircular plate 11 is installed, the semicircular ring 16 is made to fit against the semicircular plate 11, which will fit against the ball bearing 10. Then the bolts 18 are installed.

[0031] A horizontally arranged insert rod 19 is provided on the protrusion 17 and inserted into the protrusion plate 13, so that the semicircular ring 16 can be positioned when it is installed on the semicircular plate 11.

[0032] The second embodiment differs from the first embodiment in that the fixing plate 5 is provided with a fixing rod 6 with screw holes for fixing the fixing plate 5.

[0033] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0034] When the linen and cotton yarn passes through the guide wheel, it drives the guide wheel to rotate. This causes the outer ring of bearing 3 to rotate on the inner ring of bearing 3. This allows the connecting rod 7 to simultaneously drive the first ball 8, the second ball 9, and the third ball 10 to roll. The first ball 8 and the third ball 10 roll on the fixed plate 5 and the two semicircular rings 16, respectively, while the second ball 9 rolls on the two semicircular plates 11. This prevents the connecting rod 7 and the outer ring of bearing 3 from wobbling axially or radially, thus ensuring that the guide wheel does not wobble when rotating and guaranteeing precise yarn guiding of the linen and cotton yarn.
