Description

Technical Field

[0001] This application relates to the field of twisting machine technology, specifically to a thread feeding device for a twisting machine. Background Technology

[0002] In the production operation of twisting machines, the pay-off device is a key component, and its structural rationality and functional completeness directly affect production efficiency and product quality. Currently, the pay-off mechanism, conductor components, and related auxiliary structures in existing pay-off devices are scattered, with each component relatively independent and lacking organic integration. This results in the entire device occupying a large space, which not only increases the cost of using the production site but also causes inconvenience for equipment installation, debugging, and maintenance, making it difficult to meet the needs of modern production lines for equipment miniaturization and integration. In addition, whether the yarn breaks during the pay-off process mainly relies on the operator's visual observation. This manual inspection method has a significant lag. When the yarn breaks, it is often not detected and the machine cannot be stopped in time, causing the subsequent twisting mechanism to idle or perform ineffective processing. This not only produces a large number of unqualified products and wastes raw materials but also reduces production efficiency and increases production costs.

[0003] Therefore, there is an urgent need for a yarn feeding device for twisting machines that is compact, highly integrated, and capable of automatically detecting yarn breakage, in order to solve the above problems. Utility Model Content

[0004] The purpose of this application is to provide a yarn feeding device for a twisting machine to solve the problems of loose structure, large space occupation, and reliance on manual yarn breakage detection in the prior art.

[0005] The embodiments of this application can be implemented through the following technical solutions:

[0006] A wire feeding device for a twisting machine includes: a base, a bracket fixedly connected to the base, and a plurality of sets of wire feeding rollers rotatably connected to the upper surface of the base. Each set of wire feeding rollers includes a plurality of synchronously rotating wire feeding rollers evenly distributed along the circumference. The bracket is provided with a plurality of wire detectors corresponding one-to-one with each wire feeding roller. The wire drawn out from each wire feeding roller is individually detected for wire breakage by its corresponding wire detector.

[0007] Furthermore, the wire feeding roller assembly also includes a motor and a transmission assembly. The transmission assembly includes a drive wheel, a driven wheel, and a belt. The motor is fixed on the base, and the output end of the motor is connected to the drive wheel. The drive wheel is connected to the driven wheel, which is fixedly connected to the lower part of the wire feeding roller, via a belt.

[0008] Furthermore, the transmission assembly also includes a tensioning wheel, which is disposed between the driving wheel and the driven wheel on the adjacent feed roller, and the tensioning wheel abuts against the belt to adjust the belt tension.

[0009] Furthermore, the wire feeding roller assembly also includes a protective cover, which is fixedly connected to the base and coaxially sleeved on the outside of the wire feeding roller.

[0010] Furthermore, the bracket includes a longitudinal bracket and a transverse bracket. The transverse bracket includes a first transverse bracket and a second transverse bracket. The longitudinal bracket is fixed to the base in a vertical direction. The first transverse bracket and the second transverse bracket are both vertically connected to the longitudinal bracket. The installation height of the first transverse bracket is higher than that of the second transverse bracket. The probe is disposed on the second transverse bracket.

[0011] Furthermore, the first transverse support is also provided with guide wheels that correspond one-to-one with each group of pay-off rollers. The wires drawn out by all pay-off rollers in the same group of pay-off rollers pass through their respective wire probes and are then fed out through the guide wheels corresponding to that group.

[0012] Furthermore, the first transverse support is also provided with a guide member, which is correspondingly arranged with the guide wheel for combing and guiding the yarn, and the guide member is located on the side of the guide wheel away from the yarn probe.

[0013] Furthermore, the base is provided with a connecting groove corresponding to the wire feeding roller. The connecting groove is an elongated groove. The lower part of the wire feeding roller is provided with a slider that slides in cooperation with the connecting groove and is fixed in position by a locking bolt.

[0014] The wire feeding device for a twisting machine provided in the embodiments of this application has at least the following beneficial effects:

[0015] The pay-off device of this application achieves a highly compact structure and efficient functional integration by integrating multiple pay-off roller groups onto a base and cooperating with a yarn detector on a bracket. This significantly reduces the space occupied by the equipment and facilitates the compact layout of the production line. Simultaneously, each pay-off roller corresponds to an independent yarn breakage detection mechanism, enabling real-time monitoring of the yarn status and rapid response to yarn breakage, completely eliminating reliance on manual inspection, effectively reducing ineffective production and raw material waste, and significantly improving the efficiency and stability of yarn twisting production. Furthermore, the adjustable position and synchronous transmission design of the pay-off rollers allow it to flexibly adapt to different yarn types and process requirements, possessing strong practicality and adaptability.

[0029] Combination Figures 1-6 As shown in the figure, this application provides a wire feeding device for a twisting machine, including a base 11 and a bracket 12 fixed thereon. Several sets of wire feeding rollers 13 are rotatably connected to the base 11. Each set of wire feeding rollers 13 includes several wire feeding rollers 131 evenly distributed circumferentially and rotating synchronously. The bracket 12 is equipped with wire detectors 14 corresponding to each wire feeding roller 131. The wire drawn from each wire feeding roller 131 is individually detected for wire breakage by its corresponding wire detector 14. This device integrates multiple sets of wire feeding rollers onto the base, and with the corresponding wire detectors on the bracket, achieves an integrated design for synchronous wire feeding and wire breakage detection of multiple strands. During operation, the wire feeding rollers rotate synchronously under the drive of the drive assembly to release the wire. After real-time monitoring by the wire detectors, the wire is conveyed to subsequent processes. This not only significantly reduces the overall space occupied by the equipment, but also allows for timely response by the wire detectors when wire breakage occurs, effectively avoiding ineffective production caused by the lag in manual detection, and significantly improving the efficiency and stability of twisting production.

[0030] Specifically, the bracket 12 includes a longitudinal bracket 121 and a transverse bracket. The longitudinal bracket 121 is arranged vertically, that is, perpendicular to the plane of the base, and generally at least two are provided, symmetrically distributed on both sides or edges of the base 11. The transverse bracket includes a first transverse bracket 122 and a second transverse bracket 123, which extend horizontally and are respectively fixedly connected to the longitudinal bracket 121 at different heights. In some specific embodiments, the second transverse bracket 123 is located at a relatively lower position for installing the wire probe 14, and the first transverse bracket 122 is located at a relatively higher position for installing the guide wheel 15 and the guide member 16. This layered arrangement of the transverse brackets allows the various functional components to be staggered in the height direction, avoiding spatial interference and further optimizing the compactness of the overall structure.

[0031] Specifically, the pay-off roller group 13 includes a plurality of pay-off rollers 131 evenly distributed along the circumference. The number of pay-off rollers 131 can be 3, 4, 5, 6 or more, and the specific number can be determined according to the number of yarn strands to be twisted as needed.

[0032] Furthermore, to achieve synchronous rotation of the pay-off rollers 131, the pay-off roller group 13 also includes a motor 135 and a transmission assembly. The transmission assembly includes a drive wheel 132, a driven wheel, and a belt 134. The motor 135 is fixedly mounted on the base 11 via a motor mount, and its output shaft is fixedly connected to the drive wheel 132 to provide power. The driven wheel is coaxially fixed to the lower part of the pay-off roller 131. The drive wheel 132 and the driven wheel are specifically belt pulley structures. The drive wheel 132 is connected to the driven wheel at the lower part of each pay-off roller 131 in the pay-off roller group 13 via an annular belt 134.

[0033] Preferably, to ensure that the belt 134 always maintains appropriate tension and to ensure transmission efficiency and stability, the transmission assembly further includes a tensioning wheel 133. The tensioning wheel 133 is disposed between the driving wheel 132 and the driven wheel on the adjacent feed roller 131. The tensioning wheel 133 is mounted on the base 11 by an adjustable bracket, and its wheel surface abuts against the outer surface of the belt 134. When the belt 134 is slack, the position of the tensioning wheel 133 is adjusted to increase its pressure on the belt 134, thereby tensioning the belt 134.

[0034] Preferably, in order to protect the pay-off roller 131 and prevent the yarn from being contaminated by external dust and debris during the pay-off process, the pay-off roller group 13 further includes a protective cover 136. The protective cover 136 is coaxially disposed with the pay-off roller 131 on the outside of the pay-off roller 131, and its lower end is fixedly connected to the base 11.

[0035] Specifically, the yarn detector 14 employs a mature photoelectric or mechanical contact yarn breakage detection sensor, which is mounted on the second transverse support 123 and corresponds one-to-one with each pay-off roller 131, meaning one yarn detector 14 is positioned above each pay-off roller 131. The installation position of the yarn detector 14 should ensure that the yarn drawn from the pay-off roller 131 can smoothly pass through its sensing area. For example, for a photoelectric yarn detector, it has a detection hole or detection slot for the yarn to pass through. When the yarn passes normally, the yarn detector outputs a normal signal. When a yarn breakage occurs, the yarn detector immediately outputs a yarn breakage signal, which can be transmitted to the main control system of the twisting machine to control the machine to stop and issue an alarm prompt, so that the operator can handle the situation promptly.

[0036] Preferably, on the transverse support, on the side of the wire probe 14 away from the wire feeding roller group 13, a guide wheel 15 is also provided for each wire feeding roller group 13. The guide wheel 15 has an annular groove on its rim to accommodate and guide the wire. The guide wheel 15 can perform preliminary sorting and guidance on multiple wires of the same wire feeding roller group 13 after being detected by the wire probe 14, change the direction of the wires, and smoothly transport them to the subsequent guide member 16 or the take-up end, reducing friction and tangling between the wires.

[0037] Preferably, the transverse support is further provided with a guide member 16, which is located on the side of the guide wheel 15 away from the wire probe 14, and its specific structure can be as follows: Figure 3 The lock-type structure shown, or the guide block with guide hole, etc. The main function of the guide 16 is to further comb the yarn, ensuring that multiple yarns maintain a neat arrangement and appropriate tension before entering the take-up or twisting process, so as to provide a good yarn condition for subsequent processes.

[0038] Preferably, the upper surface of the base 11 is further provided with a plurality of connecting grooves 111 according to the number of pay-off rollers 131, and the connecting grooves 111 correspond one-to-one with the pay-off rollers 131. The connecting grooves 111 are designed as elongated grooves, and the lower part of the pay-off roller 131 is fixedly provided with a slider that cooperates with the connecting groove 111. The slider and the connecting groove 111 form a sliding fit, so that the pay-off roller 131 can slide along the trajectory of the elongated groove, thereby adjusting its position on the base. When the position is adjusted to the correct position, the slider can be fixed to the base 11 by locking bolts, etc., thereby fixing the position of the pay-off roller 131. This adjustable design allows the equipment to adapt to the pay-off requirements of yarns of different thicknesses and materials, or to adjust the pay-off angle according to changes in subsequent twisting processes.

[0039] The specific embodiments of this application have been described in detail above. For those skilled in the art, several improvements and modifications can be made to this application without departing from the principle of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
