Description

Technical Field

[0001] This utility model relates to the field of tensioner technology, and in particular to a multi-strand winding tensioner mechanism. Background Technology

[0002] Tensioners are core equipment for ensuring winding quality. Their tension control accuracy directly affects the tightness consistency and structural stability of the product line. The high-speed tensioner we previously applied for, application number CN202422701107.0, has an integrated tension rod design for its tension adaptive adjustment mechanism. The tension rod head is equipped with a multi-grooved wheel to achieve synchronous winding of multiple wires. An adjustable anti-tension spring rod is set on the back of the machine. The overall anti-tension is adjusted by moving the position of the spring rod on the rotating shaft.

[0003] However, in practical applications, this design has been found to have significant limitations: during multi-strand winding, the surface friction coefficient, diameter, and transmission path resistance of each strand are different, and the integrated tension bar and single anti-tension adjustment method cannot independently adapt the tension to each individual strand. This results in inconsistent tension on each conductor, ultimately leading to uneven tension in the wound product, severely affecting product quality stability and failing to meet the requirements of high-precision multi-strand winding processing. Therefore, there is an urgent need for a multi-strand winding tensioner mechanism that can achieve independent tension adjustment for each strand to overcome the shortcomings of existing technologies. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model proposes a multi-strand winding tensioner mechanism.

[0005] This utility model discloses a multi-strand winding tensioner mechanism, including a mounting base plate. Several tension rod assemblies are mounted on the front of the mounting base plate. Each tension rod assembly includes a tension rod seat rotatably connected to the front of the mounting base plate via a fixed shaft. A tension rod is connected to the outer side of the tension rod seat. A wheel seat is mounted at the end of the tension rod. A single-groove thread guide wheel is rotatably connected inside the wheel seat. A spring rod is connected to the inner side of the tension rod seat. A tension spring fixing seat is connected to the outer side of the spring rod. A tension spring is rotatably connected to the bottom end of the tension spring fixing seat. A tension spring fixing rod is rotatably connected to the bottom end of the tension spring. The tension spring fixing rod is connected to the mounting base plate.

[0006] Furthermore, a cable entry mechanism is installed at the bottom of the mounting base plate to ensure the stability of the cable entry and to protect the cable.

[0007] Furthermore, the cable tray mechanism includes a fixed base installed at the bottom of the mounting plate. The fixed base is internally threaded with a double-ended screw. The double-ended screw is covered with felt, and a locking nut is threaded to the end of the double-ended screw. A compression spring is covered with the double-ended screw. The two ends of the compression spring abut against the felt and the locking nut. A fixing plate is installed on the top of the fixed base. Several ceramic cable guides are installed on both the fixing plate and the bottom of the fixed base.

[0008] Furthermore, the front of the mounting base plate is rotatably connected to a multi-groove inlet wheel, a multi-groove tension wheel, a multi-groove tension sensing wheel, and a multi-groove outlet wheel, respectively, while the back is respectively equipped with a power device and a force sensor. The drive end of the power device is connected to the multi-groove tension wheel, and the detection end of the force sensor is rotatably connected to the rotating shaft of the multi-groove tension sensing wheel.

[0009] Furthermore, the wire enters the tensioner mechanism from the wire inlet and passes sequentially through the multi-slot wire inlet wheel, multi-slot tension wheel, multi-slot tension sensing wheel, and multi-slot wire outlet wheel, and is finally discharged from the single-slot wire guide wheel.

[0010] Furthermore, several wire breakage alarm photoelectric switches are also installed on the front of the mounting base plate. The wire breakage alarm photoelectric switches correspond to the tension rod assembly. When the tensioner mechanism is in standby mode, the end of the spring rod abuts against the detection end of the wire breakage alarm photoelectric switch. When in working mode, the end of the spring rod disengages from the detection end of the wire breakage alarm photoelectric switch.

[0011] Furthermore, an electrical control box is installed on the back of the mounting base plate, and the electrical control box is covered outside the power unit and force sensor.

[0012] Furthermore, the electrical control box contains a circuit board, with a control panel on one side and a power interface, signal line interface, and communication line interface on the other side.

[0013] The beneficial effects of this utility model are as follows: by setting up multiple independent tension rod assemblies, combined with the bidirectional adjustment structure of the tension spring fixing rod and the tension spring fixing seat, the tension requirements of each wire can be accurately matched, ensuring that the tension of each wire is consistent during the multi-strand winding process. At the same time, with the protection and wire breakage alarm functions of the wire feeding position winding mechanism, the product line quality stability is significantly improved and quality accidents are reduced.

[0016] Reference Figure 1-7 This utility model proposes a multi-strand winding tensioner mechanism, including a mounting base plate 1. Various functional components are rationally arranged on its front and back sides, providing stable support and an integrated mounting platform for tension control of multi-strand winding. Several sets of independently operating tension rod assemblies 2 are mounted on the front of the mounting base plate 1. Each set of tension rod assemblies 2 corresponds to the tension adjustment of a single strand of wire and is the core component for achieving independent tension control of a single strand of wire. The specific technical solution is as follows: The tension bar assembly 2 specifically consists of a tension bar seat 21, a tension bar 22, a single-groove wire guide wheel 23, a spring bar 24, a tension spring fixing seat 25, a tension spring 26, and a wheel seat 27. The tension bar seat 21 is rotatably connected to the front of the mounting base plate 1 via a fixed shaft 13, and its outer side is fixedly connected to the tension bar 22. The end of the tension bar 22 is equipped with a wheel seat 27, and the single-groove wire guide wheel 23, which is rotatably connected inside the wheel seat 27, is used for the final guide and discharge of single strands of wire. The inner side of the tension bar seat 21 is connected to the spring bar 24, and the spring bar 24 is fitted with a tension spring fixing seat 27. 5. The bottom end of the tension spring fixing seat 25 is connected to the tension spring fixing rod 12 via a rotatably connected tension spring 26. The tension spring fixing rod 12 is fixed to the mounting base plate 1. By adjusting the position of the tension spring fixing rod 12 on the mounting base plate 1 and the position of the tension spring fixing seat 25 on the spring rod 24, the counter-tension of the corresponding tension rod assembly 2 can be precisely adjusted to ensure that the tension of each wire is consistent. At the same time, a bearing is installed between the tension rod seat 21 and the fixed shaft 13 to ensure flexible operation. The tension spring assembly can rotate around the connecting parts to realize the free extension and retraction of the tension spring 26. To ensure the stability of the incoming wire and protect it, a wire feeding mechanism 3 is installed at the bottom of the mounting base 1. This mechanism includes a fixed base 31, a double-ended screw 32, a felt 33, a locking nut 34, a compression spring 35, a fixing plate 36, and a ceramic wire guide 37. The fixed base 31 is fixed to the mounting base 1, and the double-ended screw 32 is internally threaded. The double-ended screw 32 is covered with a felt 33, and the end is threaded with a locking nut 34. The two ends of the compression spring 35 on the outside of the double-ended screw 32 abut against the felt 33 and the locking nut 34, respectively, forming a flexible clamping protection for the wire. A fixing plate 36 is installed on the top of the fixed base 31, and several ceramic wire guides 37 are installed on both the fixing plate 36 and the bottom of the fixed base 31. A special double-groove ceramic wire guide design simplifies the wire feeding structure and guides the wire into the subsequent mechanism in an orderly manner. The front of the mounting base plate 1 is rotatably connected to a multi-slot inlet wheel 4, a multi-slot tension wheel 5, a multi-slot tension sensing wheel 6, and a multi-slot outlet wheel 7. The back is equipped with a power unit 8 and a force sensor 9. The power unit 8 is a hysteresis brake or a motor, and the drive end of the power unit 8 is connected to the multi-slot tension wheel 5 to provide power to the multi-slot tension wheel 5 and realize active tension adjustment. The detection end of the force sensor 9 is rotatably connected to the rotating shaft of the multi-slot tension sensing wheel 6 to detect the tension change of the wire in real time. After the wire enters from the inlet cable laying mechanism 3, it passes through the multi-slot inlet wheel 4, the multi-slot tension wheel 5, the multi-slot tension sensing wheel 6, and the multi-slot outlet wheel 7 in sequence, and is finally discharged through the single-slot cable guide wheel 23, forming a complete cable path to ensure that multiple strands of wire are transmitted synchronously and orderly. To promptly detect wire breakage issues, several wire breakage alarm photoelectric switches 10 are installed on the front of the mounting base plate 1, each corresponding to a tension rod assembly 2. When the mechanism is in standby mode, the end of the spring rod 24 abuts against the detection end of the wire breakage alarm photoelectric switch 10 (as shown in the attached diagram). Figure 7 As shown in the left figure), in the working state, the end of the spring rod 24 disengages from the detection end (as shown in the attached figure). Figure 7 (As shown in the right figure) If a strand of wire breaks, the corresponding tension rod assembly 2 loses the tension of the wire, and the spring rod 24 will reset under the action of the tension spring 26 and touch the detection end, triggering the wire breakage alarm photoelectric switch 10 to alarm and stop the machine, reducing quality accidents; An electrical control box 11 is also installed on the back of the mounting base plate 1. It covers the power unit 8 and the force sensor 9, serving as a protective and integrated unit. The electrical control box 11 contains a circuit board 111. One side has a control panel 112, and the other side has a power interface 113, a signal line interface 114, and a communication line interface 115. The circuit board 111 receives the tension signal detected by the force sensor 9 and, in conjunction with the set parameters of the control panel 112, controls the power unit 8 to adjust the speed of the multi-groove tension wheel 5, thereby achieving closed-loop tension control. The various interfaces facilitate signal transmission and communication between the mechanism and external power sources, control systems, and other equipment, ensuring the automated operation of the entire mechanism.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
