Description

Technical Field

[0001] This utility model relates to the field of ring spinning machine technology, and in particular to a yarn breakage treatment device for ring spinning machines. Background Technology

[0002] Ring spinning machines are core equipment widely used in the spinning industry. They are mainly used to further draft and twist roving (or sliver) into fine yarn with a certain fineness and strength.

[0003] In the ring spinning production sector, small and medium-sized enterprises (SMEs) are limited by equipment investment and technology costs, and generally still adopt a manual experience-based yarn breakage handling mode. This traditional method relies on operators to inspect and detect yarn breaks in real time. This not only suffers from the problem of delayed yarn breakage identification, but also requires workers to manually connect the two ends of the yarn based on their operating experience. This is not only time-consuming, but also prone to insufficient connection accuracy, which can lead to a decrease in the strength of the yarn joint and further affect the quality of subsequent fabrics. At the same time, the large amount of idle time directly causes a significant loss of production efficiency, making it difficult to meet the needs of SMEs for production continuity and cost control.

[0004] To address the aforementioned issues, we propose a yarn breakage handling device for ring spinning machines. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a yarn breakage treatment device for ring spinning machines.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A yarn breakage handling device for a ring spinning machine includes a single-row frame of the ring spinning machine, a guiding sensing mechanism, and a yarn receiving assembly. The yarn receiving assembly includes a chassis, a permanent magnet fixedly installed at the center of the bottom of the chassis, an insert cylinder fixedly installed on the upper side of the chassis, a lower rotating cylinder movably inserted into the inner side of the insert cylinder, an upper rotating cylinder rotatably installed on the upper side of the lower rotating cylinder, a through-slot for wiring is formed along the entire length of the side walls of the lower and upper rotating cylinders, protrusions are evenly distributed on the inner walls of the lower and upper rotating cylinders, and a rubber gasket is fixedly adhered to the periphery of the chassis.

[0008] Furthermore, the guiding sensing mechanism includes a folding rod, a bushing is rotatably sleeved on the outer side of the folding rod, and a guide wheel is fixedly sleeved on the outer side of the bushing.

[0009] Furthermore, tension sensors are symmetrically fixedly installed on the inner end of the folding rod, and structural seats are fixedly installed on the inner side of the tension sensors. The structural seats are screwed onto the side wall of a single row of the ring spinning machine frame.

[0010] Furthermore, a controller and an alarm light are fixedly installed on the side wall of the single-row frame of the ring spinning machine.

[0011] Furthermore, a rotating column is rotatably installed on the side wall of a single row of the ring spinning machine frame, a yarn bobbin is sleeved on the outside of the rotating column, and a lower limit cover is screwed onto the outer end of the rotating column.

[0012] Furthermore, a servo motor is fixedly installed on the side of the single-row frame of the ring spinning machine, a rotating shaft is fixedly installed on the output end of the servo motor, a yarn winding cylinder is sleeved on the outside of the rotating shaft, and a limit cover is fastened to the end of the rotating shaft.

[0013] Furthermore, the outer wall of the rotating shaft is provided with a snap-fit ​​protrusion, and the inner wall of the yarn winding drum is provided with a snap-fit ​​groove that matches the snap-fit ​​protrusion.

[0014] Compared with related technologies, the yarn breakage handling device for a ring spinning machine proposed in this utility model has the following beneficial effects:

[0015] This invention discloses a yarn breakage handling device for a ring spinning machine. Through a yarn splicing assembly and a guiding sensing mechanism, the yarn splicing assembly is magnetically attached to a single-row frame of the ring spinning machine using a permanent magnet. This allows for easy movement and fixation, facilitating timely use. When a yarn breakage occurs during the winding process, the tension signal on the tension sensor of the guiding sensing mechanism drops sharply, indicating a yarn breakage. At this time, the controller activates an alarm light to prompt the operator to handle the situation promptly. The operator then pulls the lower drum out from the inside of the insert drum, aligns the two ends of the broken yarn, and inserts them into the inside of the upper and lower drums from the side of the slot. The upper and lower drums are then rotated in opposite directions, causing the yarn inside to spirally connect. This quickly completes the yarn breakage handling process without relying on operator experience. The connected yarn is then pulled out from the side of the slot. The entire operation is convenient and quick. Compared to the wiring methods used in some small and medium-sized enterprises that rely on operator experience, this device offers the advantages of timely response to yarn breakage signals and rapid yarn splicing, reducing the impact of yarn breakage on production efficiency.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] Reference Figures 1-8 A yarn breakage handling device for a ring spinning machine includes a single-row frame 1, a guide sensing mechanism 5, and a yarn receiving assembly 6. The yarn receiving assembly 6 includes a chassis 61, a permanent magnet 62 fixedly installed at the bottom center of the chassis 61, an insert 64 fixedly installed on the upper side of the chassis 61, a lower rotating drum 65 movably inserted into the inner side of the insert 64, an upper rotating drum 66 rotatably installed on the upper side of the lower rotating drum 65, a wiring groove 67 extending along the side walls of the lower rotating drum 65 and the upper rotating drum 66, protrusions 68 evenly distributed on the inner walls of the lower rotating drum 65 and the upper rotating drum 66, and rubber gaskets 63 fixedly adhered to the ground periphery of the chassis 61.

[0027] Through the above-described configuration, the permanent magnet 62 enables rapid magnetic fixation of the yarn splicing assembly 6 to the single-row frame 1 of the ring spinning machine, eliminating the need for complex installation operations and facilitating flexible relocation of the yarn splicing assembly 6 by staff according to the yarn breakage position. The insert 64 provides stable insertion support for the lower rotating drum 65, ensuring that the lower rotating drum 65 remains vertical during use. The rotational cooperation between the lower rotating drum 65 and the upper rotating drum 66 allows the protrusion 68 on the inner wall to drive the overlapping parts of the yarn ends to form a spiral connection through opposite rotation (here, the overlapping spiral winding method at the yarn ends is adopted, which, compared with the traditional knotting and splicing method, has no obvious traces at the broken yarn joint). Since the yarn is in a fluffy state before twisting, the spiral winding splicing method can maintain the splicing strength and make reasonable use of the fluffy physical state of the yarn before twisting, replacing manual splicing and improving splicing efficiency and accuracy; the splicing groove 67 makes it convenient for workers to put the two ends of the broken yarn into the inside of the drum from the side, and at the same time, it is convenient to pull out the yarn after splicing; the rubber gasket 63 can increase the friction of the base 61 adsorbed on the surface of the frame by the permanent magnet 62, preventing the splicing assembly 6 from sliding during use, and also making it easy to place the splicing assembly 6 stably on the corresponding ring spinning machine single row frame 1.

[0028] In this method, the guiding sensing mechanism 5 includes a folding rod 51, a bushing 52 is rotatably sleeved on the outside of the folding rod 51, a guide wheel 53 is fixedly sleeved on the outside of the bushing 52, a tension sensor 54 is symmetrically fixedly installed on the inner end of the folding rod 51, a structural seat 55 is fixedly installed on the inner side of the tension sensor 54, and the structural seat 55 is screwed onto the side wall of the single row frame 1 of the ring spinning machine.

[0029] Through the above-described configuration, the bending rod 51 provides a mounting carrier for the bushing 52 and the guide wheel 53. Its bending structure can adapt to the side wall space of the single-row frame 1 of the ring spinning machine, ensuring that the guide wheel 53 is on a reasonable path for yarn transmission. The cooperation between the bushing 52 and the guide wheel 53 allows the yarn to slide along the surface of the guide wheel 53 during transmission, reducing frictional loss between the yarn and other components. The tension sensor 54 can monitor the yarn tension on the bending rod 51 in real time. When yarn breakage occurs, the signal of sudden reduction in tension can be promptly transmitted to the controller 7. The structural base 55 securely mounts the guide sensing mechanism 5 on the side wall of the single-row frame 1 of the ring spinning machine through a screw connection, ensuring that the sensing mechanism does not shift during yarn transmission and ensuring the accuracy of tension detection.

[0030] In this method, a servo motor 9 is fixedly installed on the upper side of the single-row frame 1 of the ring spinning machine. A rotating shaft 10 is fixedly installed on the output end of the servo motor 9. A yarn winding drum 11 is sleeved on the outer side of the rotating shaft 10. A limit cover 12 is fastened to the end of the rotating shaft 10. A snap-fit ​​protrusion is provided on the outer wall of the rotating shaft 10. A slot that matches the snap-fit ​​protrusion is provided on the inner wall of the yarn winding drum 11.

[0031] With the above configuration, the servo motor 9 provides power for the rotation of the shaft 10, and the speed can be adjusted according to the spinning requirements to achieve precise control of the yarn winding speed. The shaft 10, through the engagement protrusion on the outside, cooperates with the groove on the inner wall of the yarn winding drum 11, which can drive the yarn winding drum 11 to rotate synchronously, avoiding relative slippage between the two during the yarn winding process and ensuring the uniformity of the yarn winding. The yarn winding drum 11 is used to wind the processed fine yarn and complete the yarn collection. The limiting cover 12 can axially limit the yarn winding drum 11 to prevent the yarn winding drum 11 from slipping off the end during the rotation of the shaft 10, ensuring the stable operation of the yarn winding process.

[0032] In this method, a controller 7 and an alarm light 8 are fixedly installed on the side wall of the single-row frame 1 of the ring spinning machine.

[0033] With the above settings, the controller 7 can receive the signal transmitted by the tension sensor 54. When a sudden drop in tension is detected and it is determined to be a yarn breakage, it immediately sends a command to the alarm light 8. The alarm light 8 lights up after receiving the command from the controller 7, which can quickly remind the staff that a yarn breakage has occurred on site, shorten the yarn breakage response time, and avoid the spindle running idle for a long time, which would cause production efficiency loss. At the same time as the alarm light 8 lights up, the servo motor 9 stops driving synchronously.

[0034] In this method, a rotating column 2 is rotatably installed on the side wall of the single-row frame 1 of the ring spinning machine, a yarn cylinder 4 is sleeved on the outside of the rotating column 2, and a lower limit cover 3 is screwed to the outer end of the rotating column 2.

[0035] With the above configuration, the rotating column 2 provides rotational support for the yarn bobbin 4, allowing the yarn bobbin 4 to rotate freely during yarn traction, ensuring that the roving (or sliver) can be smoothly transferred to subsequent processes; the yarn bobbin 4 is used to hold the roving (or sliver) to be processed and is a storage carrier for spinning raw materials; the lower limit cover 3 is fixed to the outer end of the rotating column 2 by screw connection, which can axially limit the yarn bobbin 4, prevent the yarn bobbin 4 from falling off the rotating column 2 during rotation, and ensure a stable supply of raw materials.

[0036] The working principle of the yarn breakage treatment device for a ring spinning machine provided by this utility model is as follows:

[0037] When the device is operating normally, the roving (or sliver) on the yarn drum 4 passes around the guide wheel 53 of the guide sensing mechanism 5 in sequence and finally winds onto the yarn winding drum 11. At this time, the servo motor 9 drives the rotating shaft 10 to rotate the yarn winding drum 11, realizing the traction and winding of the yarn. At the same time, the tension sensor 54 monitors the tension of the yarn on the guide wheel 53 in real time and transmits the signal to the controller 7. When a yarn breakage occurs, the yarn tension decreases sharply. After receiving the abnormal signal from the tension sensor 54, the controller 7 immediately controls the alarm light 8 to light up to remind the staff, and at the same time controls the servo motor 9 to stop running to prevent the yarn winding drum 11 from running dry.

[0038] After the staff discovers the alarm, they can handle it with the help of the yarn splicing assembly 6: First, pull the lower drum 65 out from the inside of the insert drum 64, align the two ends of the broken yarn, and insert it into the inside of the two drums through the wiring groove 67 on the side wall of the lower drum 65 and the upper drum 66. Then, rotate the upper drum 66 and the lower drum 65 in opposite directions. The protrusions 68 on the inner wall of the two drums will drive the yarn to form a spiral connection, completing the splice. Then, pull the spliced ​​yarn out from the wiring groove 67. Finally, restart the servo motor 9 through the controller 7, and the device will resume normal yarn winding operation. The whole process is quick and convenient, does not rely on manual experience, and greatly shortens the yarn breakage handling time.

[0039] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
