Description

Technical Field

[0001] This application relates to the technical field of cable processing equipment, and in particular to a cable stranding machine. Background Technology

[0002] Cables are devices used to transmit electrical energy or signals, and are typically composed of several or groups of conductors. To twist multiple individual conductors into a single strand to meet the wire manufacturing requirements, a stranding machine is used to twist them together. This improves the cable's mechanical properties, flexibility, and other characteristics, meeting the needs of different applications. Therefore, the stranding machine is an important piece of cable production equipment.

[0003] A search revealed Chinese Patent Publication No. CN213905025U, which discloses a cable stranding machine, relating to the field of cable processing equipment. The machine includes a frame, with a rotating cylinder rotatably mounted at one end of the frame. A drive device for driving the rotating cylinder is fixed to one end of the frame, and a take-up device for winding cable is fixed to the other end of the frame. Multiple locking rings are equidistantly fixed to the circumferential wall of the rotating cylinder. Multiple rotating wheels of different radii are detachably mounted on the rotating cylinder at the locking rings. Multiple unwinding rollers, each containing cable material, are equidistantly and detachably mounted on the rotating wheels. This application facilitates the quick disassembly and replacement of the unwinding rollers while stranding the cable, and also allows for adjustments to the number of rotating wheels, thereby simplifying the adjustment of the number of unwinding rollers.

[0004] Although the aforementioned patents can wind cable raw materials into finished cables, the lack of effective positioning and stabilizing structures makes the cables prone to deviation during transmission, causing them to stray from the predetermined transmission track. This makes it difficult to accurately execute subsequent processing steps. On the other hand, the frequent swaying of the cable during transmission makes its position unstable during the twisting process. This instability seriously interferes with the accurate measurement of various parameters of the cable by the measuring components, which not only leads to fluctuations in product quality and increases the defect rate, but also affects the accuracy of automated control in the production process, reduces overall production efficiency, and increases production costs. Utility Model Content

[0005] The purpose of this application is to provide a cable stranding machine, which aims to improve the problem that cables are prone to deviation, shaking, and unstable position during transmission, leading to inaccurate measurements by the measuring components.

[0006] This application provides a cable stranding machine with the following technical solution: A cable stranding machine includes a foundation, a docking mechanism is provided at the top center of the foundation, a straightening mechanism is provided on the top left side of the foundation, and a winding mechanism is provided on the top right side of the foundation. The docking mechanism includes a support frame, the bottom of which is fixedly connected to the top center of the foundation. A placement frame is fixedly connected to the top of the support frame, a side plate is fixedly connected to the outside of the placement frame, and movable frames are fixedly connected to both outer sides of the placement frame. A limiting roller is slidably connected to both inner sides of the movable frame, and a contraction spring is sleeved inside the movable frame. Fixed rollers are rotatably connected to both outer sides of the side plate, and movable rollers are slidably connected to both outer sides of the side plate. A return spring is sleeved on both outer sides of the side plate, and a measuring component is fixedly connected to the outside of the side plate. Through the above technical solution: during operation, when the cable is squeezed by external force within the placement frame of the docking mechanism, the limiting roller inside the movable frame limits the cable under the action of the contraction spring to prevent it from deviating. The movable roller outside the side plate can adaptively adjust the clamping force on the cable under the action of the reset spring to ensure that the cable is docked under appropriate tightness. At the same time, the measuring component monitors the relevant parameters of the cable in real time to provide data for subsequent stranding. The straightening mechanism straightens the cable output from the docking mechanism.

[0007] Preferably, the straightening mechanism includes a setting frame, the top of which is fixedly connected to the bottom of the foundation, and two mounting seats are fixedly connected to both sides of the top of the setting frame. A rotating shaft is rotatably connected to the adjacent side of the two mounting seats, and a winding roller is fixedly connected to the outside of the rotating shaft. Multiple grooves are formed on the outside of the winding roller. By adopting the above technical solution, when the straightening mechanism is running, the cables output from the docking mechanism enter the setting frame and are embedded in the wire grooves outside the winding drum. As the rotating shaft drives the winding drum to rotate, the cables can be arranged neatly and orderly under the constraint of the wire grooves, avoiding mutual tangling and disorder, effectively improving the efficiency and regularity of cable arrangement, and ensuring that the cables are in a good arrangement state.

[0008] Preferably, a frame is fixedly connected to the top left side of the foundation, and a sliding roller is rotatably connected to the top of the frame; By adopting the above technical solution, the cable first contacts the sliding roller at the top of the frame. The sliding roller can rotate freely. When the cable contacts the surface of the sliding roller and moves relative to it, the rolling of the sliding roller can effectively reduce the friction force on the cable, preventing the cable from being damaged due to excessive friction. At the same time, the sliding roller can also provide some support and guidance for the cable, enabling the cable to move more smoothly towards the organizing mechanism and ensuring the stability of the cable transmission process.

[0009] Preferably, two drive frames are fixedly connected to the top left side of the foundation, and a winding roller is rotatably connected to an adjacent side of the drive frames; By adopting the above technical solution, the cable is conveyed between two drive frames and wound around a take-up roller. As the take-up roller rotates on the drive frame, the cable is continuously wound and wound.

[0010] Preferably, the winding mechanism includes a support base, the bottom of which is fixedly connected to the top right side of the foundation, a rotating wheel is fixedly connected to the top right side of the support base, a wire clamp is fixedly connected to the top middle of the support base, and a positioner is fixedly connected to the top left side of the support base. By adopting the above technical solution, after the cable enters the winding mechanism, the rotating wheel pulls the cable in the winding direction and initially winds it by its own rotation. When the cable moves to the wire presser, the wire presser applies stable and appropriate pressure to force the cable to fit tightly, effectively avoiding problems such as looseness and misalignment during the winding process, making the cable roll tight and neat. At the same time, the positioner monitors and accurately determines the position of the cable in real time.

[0011] Preferably, the measuring component includes a control cylinder, the control cylinder is externally fixedly connected to the top of the side plate, the output end of the control cylinder is fixedly connected to a movable toothed coil, the inside of the placement frame is rotatably connected to a measuring toothed coil, and the outside of the movable toothed coil is slidably connected to the outside of the side plate. By adopting the above technical solution, the measuring components are started synchronously, and the control cylinder drives the movable toothed roll to slide along the side plate so that it fits with the measuring toothed roll. When the cable moves, the friction force drives the measuring toothed roll to rotate, and the number of rotations is linearly related to the distance the cable moves.

[0012] Preferably, the bottom of the return spring is supported on the top of the movable roller, and the two ends of the contraction spring are fixedly connected to the adjacent side of the limiting roller; By adopting the above technical solution, during the cable transportation process, the reset spring and the retraction spring work together to achieve dynamic adaptive adjustment. When the cable passes through the channel formed by the movable roller and the fixed roller, the reset spring applies downward pressure to the movable roller to keep it always in contact with the cable surface. The retraction spring drives the two side limiting rollers to apply inward elastic force to the cable and slides to adjust the spacing within the movable frame track.

[0013] Preferably, the outer side of the winding drum is rotatably connected to the top inner side of the setting frame, and the cable is straightened through the wire groove outside the winding drum, and then slid outside the sliding roller and is wound up by the take-up roller. By adopting the above technical solution, the cable groove on the winding drum plays a key role. As the winding drum rotates, the cable groove accurately catches the cable, and the neatly arranged cable slides smoothly towards the slide roller. The slide roller supports and guides the cable in a low-friction rolling manner, reducing movement resistance and ensuring smooth cable delivery. Finally, the take-up roller tightly winds the cable guided by the slide roller with its own rotational traction force.

[0014] In summary, this application includes at least one of the following beneficial technical effects: 1. In this utility model, the support frame at the top center of the foundation supports the placement frame, which drives the fixed roller and movable roller on the side plate to be stably positioned. With the help of the reset spring, the vertical position of the cable is centrally fixed and elastically pressed and guided. The movable frame serves as the sliding track of the limiting roller and accommodates the retraction spring. The elastic force of the retraction spring drives the limiting roller to achieve centralized elastic restriction and guidance of the cable in the horizontal direction. This achieves a comprehensive, stable and precise guiding and restriction effect on the cable, providing stable and orderly input conditions for subsequent processing steps such as cable length measurement and straightening.

[0015] 2. In this utility model, the winding drum is supported to rotate stably under the cooperation of the mounting base and the rotating shaft. The wire groove on the outside of the winding drum arranges the cable in a regular manner. Then, the sliding roller on the frame guides and supports the arranged cable. It cooperates with the winding roller on the drive frame so that the winding roller can wind and wind the cable in an orderly manner. This solves the problem that the cable is easily tangled and knotted during the winding process due to disorder and mess, resulting in low winding efficiency and poor product quality.

[0017] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0018] Example: A cable stranding machine, referring to... Figure 1 , Figure 3 , Figure 4 and Figure 5 The present invention includes a cable stranding machine, comprising a base 1 for mounting the entire device, a docking mechanism 2 provided at the top center of the base 1, a straightening mechanism 4 provided at the top left side of the base 1, and a winding mechanism 5 provided at the top right side of the base 1. The docking mechanism 2 includes a support frame 21, which provides a stable support foundation for the entire docking mechanism 2. The bottom of the support frame 21 is fixedly connected to the top center of the foundation 1. A placement frame 22 is fixedly connected to the top of the support frame 21. The placement frame 22 is used to install and constrain the entire docking mechanism 2. A side plate 26 is fixedly connected to the outside of the placement frame 22. The side plate 26 is used to install the fixed roller 27, the movable roller 28, the return spring 29, and the measuring assembly 3, providing a mounting foundation and support for these components. Movable frames 23 are fixedly connected to both sides. The movable frames 23 provide a sliding track for the limiting rollers 24 and also accommodate the retraction springs 25 to achieve elastic restriction and guidance of the cable. The limiting rollers 24 are slidably connected to both sides inside the movable frames 23. The limiting rollers 24 cooperate with the retraction springs 25 to restrict and guide the cable passing through the docking mechanism 2. The retraction springs 25 are sleeved inside the movable frames 23. The retraction springs 25 provide elastic force to the limiting rollers 24, so that the limiting rollers 24 can adaptively maintain contact with the cable to achieve elastic restriction of the cable. Fixed rollers 27 are rotatably connected to both outer sides of the side plate 26. The fixed rollers 27 fix and guide the cable passing through the docking mechanism 2, providing a stable reference path for cable docking. Movable rollers 28 are slidably connected to both outer sides of the side plate 26. The movable rollers 28 cooperate with the return springs 29 to elastically compress and guide the cable, adapting to changes in cable diameter and ensuring the stability of the cable during docking. Return springs 29 are sleeved on both outer sides of the side plate 26. The return springs 29 provide a return force to the movable rollers 28, allowing the movable rollers 28 to return to their initial position after changes in cable diameter or the disappearance of external force, ensuring continuous and effective compression and guidance of the cable. A measuring component 3 is fixedly connected to the outside of the side plate 26. The bottom of the return springs 29 is supported on the top of the movable rollers 28. The two ends of the contraction springs 25 are fixedly connected to the adjacent side of the limiting rollers 24. Specifically, the foundation 1 serves as the installation base for the entire cable stranding machine. A docking mechanism 2 is located in the middle of its top. In the docking mechanism 2, the bottom of the support frame 21 is fixed to the top of the foundation 1, and the top is connected to the placement frame 22, providing stable support and installation space for the docking mechanism 2. The movable frames 23 on both sides of the placement frame 22 have sliding connection of limiting rollers 24 inside. A contraction spring 25 is sleeved between the rollers, which can adaptively fit the cable through elastic force to achieve guidance and restriction. At the same time, the side plates 26 fixed to the outside of the placement frame 22 have fixed rollers 27 rotatably connected to both sides to provide a stable reference path for cable docking. Movable rollers 28 are also slidably connected to both sides. A return spring 29 is sleeved on the top of the rollers, which can elastically press the cable to adapt to diameter changes and ensure docking stability. After the external force disappears, the return spring 29 returns the movable rollers 28 to their original position. A measuring component 3 is also fixed to the outside of the side plate 26 for measuring relevant data.

[0019] The measuring component 3 includes a control cylinder 31, which provides power to the movable toothed coil 32. Through telescopic movement, the movable toothed coil 32 is moved to control the measuring toothed coil 33 and measure the cable length. The control cylinder 31 is externally fixedly connected to the top of the side plate 26. The output end of the control cylinder 31 is fixedly connected to the movable toothed coil 32. Under the drive of the control cylinder 31, the movable toothed coil 32 cooperates with the measuring toothed coil 33 to measure the cable length and transmit measurement data. The measuring toothed coil 33 is rotatably connected inside the placement frame 22. The measuring toothed coil 33 converts the cable's movement distance into its own rotation number through contact and rotation with the cable, thereby realizing the measurement of the cable length. The movable toothed coil 32 is externally slidably connected to the outside of the side plate 26. Specifically, the measuring component 3 is installed on the top of the side plate 26. Its core component, the control cylinder 31, provides power for the entire measurement operation. The output end of the control cylinder 31 is fixedly connected to the movable toothed coil 32. The movable toothed coil 32 can be driven to slide outside the side plate 26 through telescopic movement. The measuring toothed coil 33 is rotatably connected inside the placement frame 22. During operation, the cable moves and drives the measuring toothed coil 33 to rotate, converting the moving distance of the cable into the number of rotations of the cable itself, thereby realizing length measurement.

[0020] Reference Figure 1 and Figure 2 The straightening mechanism 4 includes a setting frame 41, which provides an installation foundation and support. The top of the setting frame 41 is fixedly connected to the bottom of the foundation 1. Two mounting seats 42 are fixedly connected to both sides of the top of the setting frame 41. The mounting seats 42 are used to install the rotating shaft 43, which provides rotational support for the winding drum 44 and ensures that the winding drum 44 can rotate stably. The rotating shaft 43 is rotatably connected to the adjacent side of the two mounting seats 42. The rotating shaft 43 connects the winding drum 44 and the mounting seats 42, transmits torque, and enables the winding drum 44 to rotate around it, thereby realizing the straightening operation of the cable. The rotating shaft 43 is fixedly connected to a winding drum 44. The winding drum 44 uses grooves 45 on its outside to organize the cables, so that multiple cables are arranged in an orderly manner in a certain way, which facilitates the subsequent winding operation. The winding drum 44 has multiple grooves 45 on its outside. The grooves 45 are the key structures on the winding drum 44 for organizing the cables. Through its shape and size design, the cables are accurately positioned and arranged. A frame 46 is fixedly connected to the top left side of the foundation 1. The frame 46 is used to install the sliding roller 47, providing support and fixation for the sliding roller 47, and also playing a certain guiding and protective role for the movement of the cable. The top of the frame 46 is rotatably connected to the sliding roller 47. The sliding roller 47 guides and supports the cable after it has been straightened by the winding drum 44, reducing the friction of the cable during movement, so that the cable can be smoothly wound by the take-up roller 49. Two drive frames 48 are fixedly connected to the top left side of the foundation 1. The drive frames 48 are used to install the take-up roller 49, providing rotational support and drive connection for the take-up roller 49, so that the take-up roller 49 can rotate and wind up the cable. The take-up roller 49 is rotatably connected to the adjacent side of the drive frame 48. The take-up roller 49 is the core component of the straightening mechanism 4 to realize cable winding. It winds and winds up the cable after it has been straightened by the winding drum 44 and guided by the sliding roller 47, which facilitates the storage and transportation of the cable. The outer side of the winding drum 44 is rotatably connected to the top inner side of the setting frame 41. The cable is straightened through the wire groove 45 outside the winding drum 44, and then slid outside the sliding roller 47 before being wound up by the winding roller 49. Specifically, on the top left side of the foundation 1, two mounting seats 42 are provided on each side of the top of the frame 41 to support the rotating shaft 43. The rotating shaft 43 passes through the mounting seats 42 and is fixedly connected to the winding drum 44, driving the drum to rotate. The groove 45 on the outer surface of the winding drum 44 is the core structure for cable straightening, which can accurately position and arrange multiple cables so that they can enter the next process in an orderly manner. At the same time, the top of the frame 46 on the left side of the foundation 1 is rotatably connected to the sliding roller 47. The cable straightened by the winding drum 44 slides on the surface of the sliding roller 47, reducing friction and obtaining guiding support. In addition, two drive frames 48 are fixed to the left side of the foundation 1, and the winding roller 49 rotatably connected to their inner side is responsible for winding and winding the cable after it has been guided by the sliding roller 47, completing the entire process of cable from dispersed to centralized collection, which is convenient for subsequent storage and transportation. The bottom of the winding drum 44 is rotatably connected to the inner top of the frame 41 to ensure that it maintains stable operation during cable straightening operations.

[0021] Reference Figure 1 and Figure 2 The winding mechanism 5 includes a support base 51, which serves as the basic support component of the winding mechanism 5, providing a stable mounting base for the rotating wheel 52, the wire presser 53, and the positioner 54, ensuring the stability of each component of the winding mechanism 5 during operation. The bottom of the support base 51 is fixedly connected to the top right side of the foundation 1. The rotating wheel 52 is fixedly connected to the top right side of the support base 51. The rotating wheel 52 is used to transport and wind multiple cables. The wire presser 53 is fixedly connected to the top middle of the support base 51. The wire presser 53 is used to apply appropriate pressure to the cable, keeping the cable tightly arranged during the winding process and avoiding loosening or twisting, ensuring that the wound cable is tight and neat after winding. The positioner 54 is fixedly connected to the top left side of the support base 51. The positioner 54 is used to accurately determine the position of the cable in the subsequent process, providing an accurate positioning reference for the cable, ensuring that the cable is operated according to the predetermined trajectory and method, and guaranteeing the winding quality. Specifically, on the top right side of the foundation 1, the support base 51 serves as the foundation of the winding mechanism 5, firmly connecting to the foundation 1 and providing an installation platform for the other components. The rotating wheel 52 on its top right side undertakes the cable conveying and winding work, allowing multiple cables to converge in an orderly manner. The wire clamp 53 in the middle of the top continuously applies pressure to the cable, ensuring that the cable fits tightly during the winding process, preventing loosening and twisting, and ensuring that the finished cable roll is neat and tight. The locator 54 on the top left side accurately positions the cable path, providing a reliable reference for subsequent winding operations.

[0022] The implementation principle of this application embodiment is as follows: Multiple thin cables first pass through the winding mechanism 5 on the top right side of the foundation 1. The rotating wheel 52 on the support seat 51 is responsible for conveying and winding the multiple cables. The wire presser 53 applies pressure to the cables to make them tightly arranged. The positioner 54 provides an accurate positioning reference for the cables and completes the winding of the cables. Then, they pass through the docking mechanism 2. The support frame 21 in the middle of the top of the foundation 1 supports the placement frame 22. The fixed roller 27 and movable roller 28 on the side plate 26 cooperate with the return spring 29 to centrally fix and elastically press and guide the upper and lower positions of the cables. The limiting roller 24 and the contraction spring 25 in the movable frame 23 provide horizontal centralized elastic restriction and guidance for the cables. At the same time, the measuring component 3 on the side plate 26 starts to work. The control cylinder 31 drives the movable toothed coil 32 to move, which cooperates with the measuring toothed coil 33 in the placement frame 22 to convert the moving distance of the cable into the number of rotations of the measuring toothed coil 33, thereby realizing the measurement of the cable length. After being processed by the docking mechanism 2, the cable enters the straightening mechanism 4 on the top left of the foundation 1. The mounting seat 42 on the setting frame 41 supports the winding drum 44 through the rotating shaft 43. The wire groove 45 outside the winding drum 44 straightens and arranges the cable. The sliding roller 47 on the frame 46 guides and supports the straightened cable. The winding roller 49 on the drive frame 48 winds and winds the cable.
