Description

Technical Field

[0001] This utility model relates to the field of yarn guiding mechanism technology, and in particular to an anti-winding twisted yarn guiding mechanism. Background Technology

[0002] The anti-winding yarn guiding mechanism (twisting machine guide rod) is a key component in a twisting machine used to guide and comb multiple strands of yarn, preventing them from tangling and knotting during the twisting process. It typically consists of a rod-shaped body made of metal or high-strength engineering plastic and multiple guide holes distributed along the rod. Its core function is to independently guide each yarn through the guide holes before the multiple strands enter the twisting process, ensuring that the yarn is smoothly transported along a preset path and avoiding entanglement. Simultaneously, through a reasonable hole layout and structural design, it reduces tension fluctuations in the yarn during transport, providing a stable yarn condition for subsequent twisting and plying.

[0003] Existing anti-winding yarn guiding mechanisms (twisting machine guide rods) have significant shortcomings when dealing with the different conveying directions of multi-strand yarns. The main issue is the mismatch between the fixed orientation of the guide holes and the actual yarn conveying requirements. Since multi-strand yarns typically originate from different bobbins, the installation positions and unwinding angles of these bobbins vary, resulting in different conveying directions for each yarn upon reaching the guide rod. Some yarns require entering the guide holes at an angle. However, traditional guide rods have fixed guide hole orientations (e.g., perpendicular to the rod axis or at a fixed angle). When the actual conveying direction of the yarn deviates from the guide hole orientation, the yarn will form a large-angle contact with the edge of the guide hole, significantly increasing the friction between them. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose an anti-winding twisting yarn guiding mechanism to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides an anti-winding ply yarn guiding mechanism, comprising two symmetrically arranged mounting brackets, a hexagonal guide rod fixedly connected between the two mounting brackets, a plurality of linearly arrayed adjusting sleeves slidably connected to the outer surface of the hexagonal guide rod, a vertically arranged L-shaped support plate fixedly mounted on the outer surface of each adjusting sleeve by bolts, two symmetrically arranged pins inserted into the top of each L-shaped support plate, an assembly plate fixedly connected to the top of the two pins, a sleeve embedded and fixedly installed inside the assembly plate, a guide ball rotatably connected inside the sleeve, a yarn guiding hole penetrating one side of the guide ball, a locking plate fixedly connected to the bottom end of the assembly plate and slidably connected to the L-shaped support plate, a U-shaped frame fixedly connected to the inner wall of the L-shaped support plate, a spring fixedly connected to one side of the U-shaped frame, a locking pin fixedly connected to one end of the spring, and the locking pin penetrating the U-shaped frame and engaging with the locking plate.

[0007] Preferably, in any of the above solutions, the bottom end of the locking plate is inserted into the U-shaped frame, a locking hole is provided on one side of the locking plate, and the locking pin passes through the U-shaped frame and engages with the locking plate through the locking hole.

[0008] Preferably, in any of the above embodiments, the bottom of the adjusting sleeve is threaded with a locking bolt, and the top of the locking bolt is in contact with the outer surface of the hexagonal guide rod.

[0009] Preferably, in any of the above schemes, a pointer is embedded inside each of the adjustment sleeves, and a scale is embedded on the outer surface of the hexagonal guide rod, with each of the pointers corresponding to the scale.

[0010] Preferably, in any of the above solutions, the top of the L-shaped support plate has two symmetrically arranged positioning holes, and the two pins are respectively inserted into the two positioning holes.

[0011] Preferably, in any of the above solutions, two symmetrically arranged limiting rings are fixedly connected to the outer surface of the guide ball, and both limiting rings are connected to the yarn guide hole. The end of the limiting ring away from the guide ball is designed with rounded corners.

[0012] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: 1. When multiple strands of yarn are fed to the yarn guiding mechanism from different directions, the guide ball rotates within the sleeve, causing the yarn guiding hole to adjust its angle synchronously with the yarn feeding direction. As the yarn passes through the guide hole, the limiting ring, with its rounded corner design, guides the yarn smoothly into the hole, preventing direct friction with the hole edge. After adjustment, the rotating structure of the guide ball maintains the alignment between the yarn guiding hole and the yarn feeding direction, ensuring the yarn always passes along the hole's axis. The rotating connection between the guide ball and the sleeve allows the yarn guiding hole to flexibly adjust its orientation according to the yarn feeding direction, solving the problem of angular deviation between traditional fixed yarn guiding holes and multi-directional yarns, and significantly reducing friction between the yarn and the edge of the guide hole. The rounded corner design of the limiting ring further reduces yarn contact damage, preventing yarn breakage or strength reduction due to friction, ensuring the quality stability of the ply yarn, and reducing wear on the equipment caused by friction, thus extending its service life.

[0013] 2. Loosen the locking bolts and slide the adjusting sleeves along the hexagonal guide rod. Adjust the multiple adjusting sleeves to the preset spacing using the correspondence between the pointer and the scale. After adjustment, tighten the locking bolts to fix the position of the adjusting sleeves. If you need to adjust the yarn guide height, pull the locking pin to compress the spring, disengaging it from the locking hole of the locking plate. Move the assembly plate up and down to the appropriate height, then release the locking pin. The spring will reset, pushing the locking pin back into the locking hole to complete the fixation. The sliding fit between the adjusting sleeves and the hexagonal guide rod, along with the fixing structure of the locking bolts, allows for quick adjustment of the lateral spacing of each yarn guide unit, adapting to the yarn guide requirements of different yarn counts. The snap-fit ​​fit between the locking plate and the locking pin enables convenient adjustment of the assembly plate height, accommodating height differences in different yarn conveying paths. The cooperation between the pointer and the scale ensures adjustment accuracy, reduces errors from manual adjustments, improves the equipment's adaptability to various textile processes, and reduces operational difficulty and time costs.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited thereto.

[0017] like Figures 1 to 4 As shown, an anti-winding twisted yarn guiding mechanism includes two symmetrically arranged mounting brackets 1. A hexagonal guide rod 2 is fixedly connected between the two mounting brackets 1. Several linearly arrayed adjusting sleeves 3 are slidably connected to the outer surface of the hexagonal guide rod 2. A vertically arranged L-shaped support plate 4 is fixedly installed on the outer surface of each adjusting sleeve 3 by bolts. Two symmetrically arranged pins 5 are inserted into the top of each L-shaped support plate 4. An assembly plate 6 is fixedly connected to the top of the two pins 5. A sleeve 7 is embedded and fixedly installed inside the assembly plate 6. A guide ball 8 is rotatably connected inside the sleeve 7. A yarn guiding hole 9 is opened through one side of the guide ball 8. A locking plate 10 is fixedly connected to the bottom of the assembly plate 6 and slidably connected to the L-shaped support plate 4. A U-shaped frame 11 is fixedly connected to the inner wall of the L-shaped support plate 4. A spring 12 is fixedly connected to one side of the U-shaped frame 11. A locking pin 13 is fixedly connected to one end of the spring 12. The locking pin 13 passes through the U-shaped frame 11 and engages with the locking plate 10.

[0018] As an optional technical solution of this utility model, the bottom end of the locking plate 10 is inserted into the U-shaped frame 11. A locking hole 14 is provided on one side of the locking plate 10. The locking pin 13 passes through the U-shaped frame 11 and is engaged with the locking plate 10 through the locking hole 14. The bottom end of the locking plate 10 is inserted into the U-shaped frame 11 to provide guidance for the up and down movement of the locking plate 10 and ensure its smooth movement. The locking pin 13 passes through the U-shaped frame 11 and is engaged with the locking plate 10 through the locking hole 14, which can quickly fix the height of the assembly plate 6, avoid the position displacement of the assembly plate 6 due to vibration during the yarn guiding process, ensure the stability of the yarn guiding hole 9, and facilitate quick height adjustment to adapt to different yarn conveying needs.

[0019] As an optional technical solution of this utility model, the bottom of the adjusting sleeve 3 is threaded with a locking bolt 15. The top of the locking bolt 15 is in contact with the outer surface of the hexagonal guide rod 2. After the position of the adjusting sleeve 3 is adjusted, the adjusting sleeve 3 can be firmly fixed on the hexagonal guide rod 2 by tightening the locking bolt 15, which prevents the adjusting sleeve 3 from sliding during the operation of the equipment and ensures the stability of the spacing between each yarn guiding unit. At the same time, loosening the locking bolt 15 can facilitate the movement of the adjusting sleeve 3, which improves the flexibility of the yarn guiding position adjustment.

[0020] As an optional technical solution of this utility model, each adjusting sleeve 3 has a pointer 16 embedded inside, and a scale 17 is embedded on the outer surface of the hexagonal guide rod 2. Several pointers 16 correspond to the scale 17. The pointers 16 inside the adjusting sleeve 3 correspond to the scale 17 on the outer surface of the hexagonal guide rod 2, which can provide a precise scale reference when adjusting the position of the adjusting sleeve 3. This allows the operator to quickly and accurately adjust multiple adjusting sleeves 3 to the preset spacing, reducing the error of manual adjustment, ensuring the consistency of the spacing between each yarn guiding unit, and helping to improve the uniformity of multi-strand yarn plying.

[0021] As an optional technical solution of this utility model, the top of the L-shaped support plate 4 has two symmetrically arranged positioning holes 18, and two pins 5 are respectively inserted into the two positioning holes 18. The positioning holes 18 at the top of the L-shaped support plate 4 and the pins 5 are engaged to provide precise positioning for the connection between the assembly plate 6 and the L-shaped support plate 4, ensuring that the assembly plate 6 will not shift laterally or shake after installation, ensuring the positional accuracy of the guide ball 8 and the yarn guide hole 9, and also facilitating the quick disassembly and maintenance of the assembly plate 6.

[0022] As an optional technical solution of this utility model, two symmetrically arranged limiting rings 19 are fixedly connected to the outer surface of the guide ball 8. Both limiting rings 19 are connected to the yarn guide hole 9. The end of the limiting ring 19 away from the guide ball 8 is designed with rounded corners. The limiting ring 19 on the outer surface of the guide ball 8 is connected to the yarn guide hole 9, and the end away from the guide ball 8 is designed with rounded corners. This can guide and limit the yarn entering the yarn guide hole 9, and prevent the yarn from deviating or rubbing against the edge of the guide ball 8 when entering the yarn guide hole 9. The rounded corner design further reduces the frictional damage between the yarn and the limiting ring 19, and protects the integrity of the yarn.

[0023] A yarn guiding mechanism for preventing yarn winding and twisting, the working principle of which is as follows: 1): When multiple strands of yarn are conveyed to the yarn guiding mechanism from different directions, the guide ball 8 is pushed to rotate inside the sleeve 7, so that the yarn guiding hole 9 adjusts its angle synchronously with the yarn conveying direction.

[0024] 2): When the yarn passes through the yarn guide hole 9, the limiting ring 19 guides the yarn to enter smoothly through the rounded corner design, avoiding direct friction with the edge of the hole.

[0025] 3): After adjustment, the rotating structure of the guide ball 8 maintains the matching state between the yarn guide hole 9 and the yarn conveying direction, ensuring that the yarn always passes through along the axis of the hole.

[0026] In summary, this anti-winding yarn guiding mechanism, when multiple strands of yarn are fed to the yarn guiding mechanism from different directions, pushes the guide ball 8 to rotate within the sleeve 7, causing the guide hole 9 to adjust its angle synchronously with the yarn feeding direction; when the yarn passes through the guide hole 9, the limiting ring 19 guides the yarn to enter smoothly through its rounded corner design, avoiding direct friction with the edge of the hole; after adjustment, the rotating structure of the guide ball 8 maintains the matching state between the guide hole 9 and the yarn feeding direction, ensuring that the yarn always passes through along the axis of the hole. The rotating connection between the guide ball 8 and the sleeve 7 allows the yarn guide hole 9 to be flexibly adjusted according to the yarn conveying direction, solving the problem of angular deviation between the traditional fixed yarn guide hole and multi-directional yarn, and significantly reducing the friction between the yarn and the edge of the yarn guide hole 9. The rounded corner design of the limiting ring 19 further reduces yarn contact damage, avoids yarn breakage or strength reduction due to friction, ensures the quality stability of the ply yarn, and at the same time reduces wear caused by friction on the equipment, extending its service life. Loosen the locking bolt 15, push the adjusting sleeve 3 to slide along the hexagonal guide rod 2, and adjust the multiple adjusting sleeves 3 to the preset spacing by the correspondence between the pointer 16 and the scale 17. After adjustment, tighten the locking bolt 15 to fix the position of the adjusting sleeve 3. If it is necessary to adjust the yarn guide height, pull the locking pin 13 to compress the spring 12, so that it is disengaged from the locking hole 14 of the locking plate 10. After moving the assembly plate 6 up and down to the appropriate height, loosen the locking pin 13, and the spring 12 resets to push the locking pin 13 back into the locking hole 14 to complete the fixation. The sliding fit between the adjusting sleeve 3 and the hexagonal guide rod 2, along with the fixing structure of the locking bolt 15, allows for quick adjustment of the lateral spacing of each yarn guiding unit, adapting to the yarn guiding needs of yarns with different ply counts. The snap-fit ​​fit between the locking plate 10 and the locking pin 13 enables convenient adjustment of the height of the assembly plate 6, accommodating height differences in different yarn conveying paths. The fit between the pointer 16 and the scale 17 ensures adjustment accuracy, reduces errors from manual adjustments, improves the equipment's adaptability to various textile processes, and reduces operational difficulty and time costs.
