Description

Technical Field

[0001] This invention relates to the field of textile machinery and equipment technology, specifically to a multi-strand knitting yarn plying and uniform feeding device. Background Technology

[0002] Plying of knitted yarns is a core process in textile processing. By merging and layering multiple single yarns, the strength, abrasion resistance, and structural stability of the yarn are improved. It is widely used in the production and processing of knitted fabrics, home textiles, and industrial knitted accessories. In the process of plying multiple yarns, the yarn feeding stability, spacing uniformity, and tension consistency directly determine the forming quality of the plyed yarn, which is a key link in controlling the quality of the finished product.

[0003] Currently, existing multi-strand yarn plying and feeding equipment has many shortcomings in practical applications: First, most equipment lacks a precise and uniformly spaced yarn splitting structure, which easily leads to problems such as inconsistent spacing, stacking, friction, and entanglement of multi-strand yarns during the conveying process, seriously affecting the quality of the finished product and the neatness of the package; Second, existing equipment mostly adopts a uniform tension adjustment mode, which seems to speed up the plying efficiency, but cannot independently fine-tune the tension differences of individual yarns. Different strands of yarn have significant tension differences due to differences in raw materials, winding tightness, and conveying resistance. Yarns with excessive tension are easily stretched and deformed, while yarns with insufficient tension are easily loosened and piled up, resulting in a loose plying yarn structure and uneven stress. Subsequent time is required for reorganization, which actually reduces the plying efficiency.

[0004] Therefore, it is necessary to provide a new multi-strand knitting yarn plying and even-pitch feeding device to solve the above-mentioned technical problems. Summary of the Invention

When it is necessary to stop winding the twisted yarn, the vision sensor 1205 detects the second engagement block and sends a signal to shut off the winding motor, thus aligning the second engagement slot with the opening of the U-shaped winding frame 6 for easy removal. Each of the four hollow frames 1204 has a telescopic cylinder 1206 fixedly installed inside. The output shafts of the cylinders extend into the four U-shaped take-up frames 6 respectively, and the output shafts of the telescopic cylinders 1206 are slidably connected to the U-shaped take-up frames 6. Each of the four telescopic cylinders 1206 has a pressing bar 1207 fixedly installed on its output shaft. The four pressing bars 1207 are located below the four take-up rollers 601 respectively, and the side of the pressing bar 1207 closest to the take-up roller 601 is set in a hemispherical shape. By utilizing the curved shape of the hemispherical surface, it can press the ply yarn on the one hand, and form a protective layer for the yarn on the other hand, avoiding sharp edges from damaging the yarn.

[0050] In addition, in order to improve the moving stability of the U-shaped support frame 1201, two support round beams are fixed on the concave bracket on which the rodless cylinder 12 is installed, and sliding arms are fixed on both outer walls of the U-shaped support frame 1201. The two support round beams pass through the two sliding arms respectively and are slidably connected to the corresponding sliding arms.

[0051] In this embodiment, to increase the rotational resistance of the yarn roller 4010, a bearing frame 8 is fixedly installed on one outer wall of the open frame 4. Two hollow sliding sleeves 803 are provided inside the bearing frame 8. A first hydraulic cylinder 801 is fixedly installed inside the bearing frame 8. A U-shaped rod 802 is fixedly installed on the output shaft of the first hydraulic cylinder 801. The cross-section of the U-shaped rod 802 is quadrilateral. Both ends of the U-shaped rod 802 penetrate one side of the open frame 4 and extend into the corresponding hollow sliding sleeve 803. The U-shaped rod 802 and the hollow sliding sleeve 803... 03. Sliding connection: Damping clips 804 are fixedly installed on the side of each of the two hollow sliding sleeves 803 near the connecting shaft 4011. The two damping clips 804 respectively abut against and fit against the two connecting shafts 4011. Utilizing the pressure effect of the first hydraulic cylinder 801, the resistance between the damping clips 804 and the connecting shaft 4011 is increased, thereby changing the rotational resistance of the yarn roller 4010. Pressure sensors 806 are fixedly installed on the inner wall of each of the two hollow sliding sleeves 803 near the connecting shaft 4011. The U-shaped rod 802... Both ends are fixedly installed with a compression spring 805 at one end, and the other ends of the two compression springs 805 are respectively fixedly connected to two pressure sensors 806; in addition, directional grooves 9 are opened on both connecting shafts 4011, and a second hydraulic cylinder 901 is fixedly installed on the outer wall of the bearing frame 8 away from the open frame 4. The output shaft of the second hydraulic cylinder 901 extends into the bearing frame 8 and a push bar 902 is fixedly installed thereon. The output shaft of the hydraulic cylinder 901 is slidably connected to one side of the bearing frame 8, and two push bars 902 are slidably installed on the push bar 902. Two directional round rods 903 have their ends extending into the open frame 4 and inserted into the corresponding directional grooves 9. The directional round rods 903 are adapted to the directional grooves 9 and are slidably connected to one side of the open frame 4. Spring seats are fixedly fitted on both directional round rods 903, and second return springs are fitted on both directional round rods 903. One end of each second return spring is fixedly connected to the two spring seats, and the other end of each second return spring is fixedly connected to the push bar 902.

[0052] In this embodiment, in the initial state, the output shafts of the second hydraulic cylinder 901 and the fourth hydraulic cylinder are both extended, and the arc-shaped damping plate achieves a locking effect on the driven rotating head 603.

[0053] Before the device is operated, the specified bus guide ring 5 is selected according to the number of strands. The more strands, the larger the inner diameter of the bus guide ring 5 required. When selecting, first hook the pull ring and pull the alignment rod 1004 out of the corresponding alignment hole 1002. The first return spring on it is in a stretched state. Then slide the lifting bar 1001. After adjusting the corresponding bus guide ring 5 to the guide position, release the pull ring. The stretched first return spring automatically resets and brings the alignment rod 1004 into the corresponding alignment hole 1002, thereby completing the selection of the bus guide ring 5.

[0054] Then, all conductor components are positioned and installed, with the installation proceeding from the center outwards to both sides. The conductor components are connected to the positioning sockets on the top of the conveying frame 1 via the bottom connecting base plate 2 and the positioning insert arm 11. At the same time, the stabilizing insert valve is inserted into the stabilizing groove of the conveying frame 1 to achieve stable connection. The third hydraulic cylinder 1102 drives the triangular abutment block 1103 to engage in the triangular abutment groove 1101 of the positioning insert arm 11, thereby locking and fixing the conductor components, ensuring the structural stability of long-term operation, and preventing component displacement during conveying, which could lead to yarn deviation.

[0055] During the installation process described above, after each conductor assembly is installed, the next conductor assembly is not installed immediately. The yarn roller 4010, wound with a single strand of yarn, is removed and installed onto the connecting shaft 4011 of the already installed conductor assembly, and secured with bolts. Then, one end of the yarn is removed and guided through the inlet guide ring 402 on the support arm 404, passing through the tension guide roller 403, and then around the first tension roller 705 from below, then around the other tension roller 705 from above, finally exiting through the outlet guide ring 405 and passing through the bus guide ring 5 to the tie ring on the take-up roller 601, where the end is secured by knotting. The rear rotating yarn roller 4010 straightens the previously laid-out yarn. During the straightening process, the yarn needs to pass through the corresponding yarn conveying channels on the two tension rollers 705. The yarn is isolated and limited by the yarn separator ring 706. When the yarn is straightened into place, the tension sensor 408 sends a signal to stop rotating the yarn roller 4010. At the same time, the corresponding first hydraulic cylinder 801 is activated, and its output shaft extends with the U-shaped rod 802, so that the damping clamp 804 is tightly pressed against the connecting shaft 4011. After the pressure sensor 806 sends a pressure value signal, the first hydraulic cylinder 801 stops, thus completing the installation of a conductor assembly and the arrangement of one strand of yarn.

[0056] Then, following the same procedure, after each conductor assembly is installed, a strand of yarn is installed until the corresponding number of conductor assemblies are installed. Furthermore, the tension value of each strand of yarn is uniform in the initial state. After the layout is completed, each strand of yarn is individually conveyed through the isolation of the first partition 401, the second partition 406, and the yarn separator ring 706, without stacking or tangling with each other. The ends of the integrated yarns are all installed on the tie rings on the take-up roller 601, thereby forming a stranded effect.

[0057] After single-strand tension monitoring and adjustment, the multi-strand yarns are uniformly fed into a unified tension adjustment component to complete synchronous calibration and overall tension fine-tuning. During operation, the tension adjustment motor drives the bidirectional screw 701 arranged vertically inside the mouth-shaped frame 7 to rotate. The bidirectional screw 701 drives the first lifting plate 702 and the second lifting plate 703 to move synchronously in opposite directions vertically, thereby causing the two tension rollers 705 to move closer or further away from each other. This enables slight adjustment of the yarn tension, eliminates the slight tension difference between the multi-strand yarns, ensures uniform overall tension of the ply yarn and consistent conveying pace, and improves the uniformity and stability of ply forming.

[0058] After all adjustments are completed, the output shaft of the second hydraulic cylinder 901 is retracted, causing the directional rod 903 to disengage from the directional groove 9. Then, the output shaft of the fourth hydraulic cylinder is retracted, causing the arc-shaped damping plate to separate from the driven rotating head 603. Subsequently, the winding motor is started, and its output shaft drives the take-up roller 601 to rotate to begin the winding operation. At the same time, the servo motor is started, and its output shaft drives the corresponding reciprocating screw 1208 to rotate, thereby causing the reciprocating plate 1209 to move reciprocally, enabling reciprocating winding work and ensuring uniform winding.

[0059] When the take-up roller 601 reaches the take-up line, the vision sensor 1205 is activated. When it detects that the second interlocking block has rotated to the top, the take-up motor shuts off, stopping the take-up operation. The corresponding telescopic cylinder 1206 is then activated, its output shaft driving the pressure bar 1207 to rise and press the yarn, which is then cut. Next, the rodless cylinder 12 is activated, its slider moving the U-shaped support frame 1201 horizontally away from the guide frame 1, thus moving the U-shaped take-up frame 6 away from the guide frame 1 and the U-shaped support frame 10, creating more space for rotation. The switching motor is then activated, its output shaft driving the rotating shaft 1202 to rotate. After the rotating shaft 1202 has rotated 90°, the switching motor shuts off. After the four U-shaped take-up frames 6 have completed their position changes, the rodless cylinder 12 is activated, and the slider on it moves in the opposite direction with the U-shaped support frame 1201, eventually returning to its original position. Then, each strand of yarn can be pulled onto the empty take-up roller 601 and fixed in the same way as described above. Finally, the tension is adjusted, and the plying and winding work can continue. At the same time, on the other side, for the already wound take-up roller 601, the corresponding fourth hydraulic cylinder is activated, and the driven rotating head 603 is locked by the arc-shaped damping plate. The operator can then remove the take-up roller 601 with the ply yarn wound on it and replace it with an empty take-up roller 601. This process is repeated to complete the replacement of the take-up roller 601 without delaying the winding work.

[0060] Furthermore, when the yarn on the yarn roller 4010 is exhausted and needs to be replaced, the output shaft of the first hydraulic cylinder 801 is first activated to retract, releasing the resistance of the damping clamp 804 to the connecting shaft 4011. Then, the output shaft of the second hydraulic cylinder 901 is activated to extend. After extension, if the directional rod 903 does not correspond to the directional groove 9, the directional rod 903 will abut against the outer surface of the connecting shaft 4011. At this time, the second return spring is in a deeply compressed state. Then, the yarn roller 4010 is manually rotated. During the rotation, when the directional rod 903 corresponds to the directional groove 9, the second return spring resets and automatically brings the directional rod 903 into the directional groove 9, thereby achieving the positioning of the two connecting shafts 4011 and ensuring that the two first mating grooves 4012 face upwards, facilitating the replacement operation of the yarn roller 4010.

[0061] Furthermore, in practical use, the take-up roller 601 can be manufactured in various specifications, and the inner diameter of the tie ring used to fix the yarn end can also be produced according to requirements; the appropriate take-up roller 601 can be selected for winding according to the final ply thickness; and before removing the take-up roller 601 with the ply yarn wound on it, the yarn end of the ply yarn must be locked by special means, and then the pressing bar 1207 can be separated from the yarn. In addition, the rotation of the rotating shaft 1202 needs to be alternated between forward and reverse 360° to avoid tangling between the connecting wires of the components.

Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
