DETAILED DESCRIPTION
[0041] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.
[0042] like Figures 1 to 4 As shown, a tension adjustment control device for a wire doubling machine includes a support base 1 and a support wall plate 2 fixed on the support base 1. The tension adjustment control device for the wire doubling machine also includes:
[0043] At least two wire bobbin support assemblies 3 are arranged on the support base 1, and the wire bobbin support assemblies 3 are used for installing wire bobbins.
[0044] At least two wire jitter buffer components 4 are arranged on the supporting wallboard 2, and the wire jitter buffer components 4 are used to buffer the lateral stress generated when the wire is paid out.
[0045] At least two fixing blocks 5 are fixed on the supporting wall panel 2 .
[0046] The cable reel 6 is fixed on the fixing block 5 .
[0047] At least two cable tie rings 7 fixed to the supporting wall panel 2.
[0048] The inflection point buffer assembly 8 is arranged on the supporting wall panel 2, and is used to buffer the angle change stress at the inflection point during the wire transmission, and one end of the wire passes through the wire jitter buffer assembly 4, the wire bundle 6, the wire bundle ring 7 and the inflection point buffer assembly 8 from bottom to top.
[0049] The wire jitter buffer assembly 4, the fixed block 5, the wire tie ring 7 and the inflection point buffer assembly 8 are installed together on a side wall of the supporting wall panel 2 facing the supporting base 1, and the installation order is arranged from bottom to top to facilitate the subsequent wiring arrangement of the wires. The wire jitter buffer assembly 4, the fixed block 5, the wire tie ring 7 and the inflection point buffer assembly 8 are a group of wiring lines, and multiple groups of wiring lines can be distributed in parallel on the supporting wall panel 2 to realize the simultaneous arrangement and routing of multiple strands of wires, which is convenient for paralleling operations of multiple strands of wires.
[0050] like Figure 1 and Figure 3 As shown, in this embodiment, the wire jitter buffer component 4 includes:
[0051] A support block 41 is fixed laterally relative to the support wall panel 2 .
[0052] A sliding rod 42 is fixed between the two supporting blocks 41 .
[0053] The slide block 43 is slidably mounted on the slide rod 42 .
[0054] A wire loop 44 is fixed to the slider 43 .
[0055] A compression spring 45 is relatively slidably sleeved on the outside of the slide rod 42 .
[0056] A limiting plate 46 is relatively fixed to the supporting wall panel 2 in the longitudinal direction.
[0057] After the silk thread is paid out, it first passes through the wire ring 44. When the silk thread is paid out, the silk thread between the wire ring 44 and the silk thread bobbin will move back and forth axially due to the flue gas caused by the winding of the silk thread on the silk thread bobbin, so that the silk thread will receive lateral stress when paying out. The lateral stress will push the wire ring 44 and the slider 43 to slide back and forth axially on the slide rod 42. Since compression springs 45 are provided on both sides of the slider 43, the lateral stress of the silk thread is buffered by alternately compressing the two compression springs 45, thereby reducing the influence of the lateral stress on the transmission of the silk thread, greatly reducing the jitter amplitude of the silk thread, and improving the transmission stability of the silk thread.
[0058] like Figure 1 and Figure 3 As shown, in the present embodiment, the compression springs 45 are relatively distributed on both sides of the slider 43, and the two ends of the compression springs 45 are respectively fixed on the support block 41 and the slider 43. During the transmission of the silk thread, since the silk thread bobbin is horizontally placed on the support base 1, when the silk thread bobbin is unwinding, the silk thread between the silk thread bobbin and the wire ring 44 will be displaced back and forth within the lateral length range of the silk thread bobbin. When unwinding under the action of the pressurized tension, part of the pressurized tension and the inertia of the silk thread unwinding will generate lateral stress, which will cause the silk thread to shake greatly before the lateral stress is buffered. When the silk thread passes through the wire ring 44, the lateral stress will push the slider 43 to slide back and forth along the axial direction of the slide rod 42, and push the compression springs 45 arranged on both sides of the slider 43 back and forth alternately. In this process, most of the lateral stress and part of the tension on the front section of the silk thread transmission are buffered by the elastic deformation of the two relatively arranged compression springs 45, which greatly reduces the jitter amplitude during silk thread transmission and improves the stability of silk thread transmission.
[0059] like Figure 1 and Figure 4 As shown, in this embodiment, the inflection point buffer component 8 includes:
[0060] A support base 81 fixed on the supporting wall panel 2 .
[0061] The vertical shaft 82 disposed on the support base 81 is rotated.
[0062] A torsion spring 83 is sleeved on the outside of the vertical shaft 82 .
[0063] A rocker arm 84 is fixed on the vertical shaft 82 .
[0064] The coil 85 is fixed to one end of the swing arm 84 .
[0065] like Figure 1 and Figure 4 As shown, in the present embodiment, the two ends of the torsion spring 83 are respectively fixed on the support seat 81 and the rocker arm 84. By fixing the two ends of the torsion spring 83, at the corner on the wire transmission path, the bundle coil 85 and the rocker arm 84 will be affected by the component force of the tension on the wire in the direction of the wire inclination path, so that the angle between the rocker arm 84 and the supporting wall panel 2 changes, and the impact force of the rocker arm 84 when swinging is buffered by the torsion force of the torsion spring 83. Compared with the fixed guide ring setting at this place on the traditional wire-winding machine, it is difficult to buffer the tension on the wire at this place, and the problem of wire breakage may occur, affecting the normal wire-winding operation. The setting of the rocker arm 84 and the torsion spring 83 has an obvious buffering effect at this place, which effectively avoids the problem of wire breakage due to excessive tension on the wire.
[0066] like Figure 1 and Figure 2 As shown, in this embodiment, the silk thread bobbin supporting assembly 3 includes:
[0067] A first supporting block 31 and a second supporting block 32 are relatively fixed to the upper surface of the supporting base 1 .
[0068] A support rod 34 is plugged into the plug hole 33 provided on the second support block 32 .
[0069] The limit block 36 is relatively fixed to one end of the support rod 34, and the limit block 36 is sleeved with the spline groove 35 provided on the first support block 31, and a nut is threadedly installed on one end of the support rod 34 close to the second support block 32. When the wire bobbin is installed or replaced, the disassembly and installation process of the wire bobbin support assembly 3 is as follows: the nut needs to be loosened and removed, and then the support rod 34 is pulled out along its axial direction, and then the new wire bobbin is placed between the first support block 31 and the second support block 32, and the axis of the wire bobbin is aligned with the plug hole 33 and the spline groove The axis of 35 is aligned, and the support rod 34 is then passed through the spline groove 35, the silk thread bobbin and the plug hole 33 in sequence along its axial direction. Finally, the nut is threadedly installed on the support rod 34 at one end close to the second support block 32 and tightened. The installation or replacement of the silk thread bobbin can be completed, which simplifies the difficulty of replacing the silk thread bobbin and makes the replacement operation of the silk thread bobbin faster and more stable. It can also prevent the support rod 34 from rotating due to the rotation of the silk thread bobbin, affecting the wire pay-off effect and the online tension during wire transmission, thereby improving the stability of wire pay-off.
[0070] like Figure 1 As shown, in this embodiment, the wire drawing machine tension adjustment control device also includes a wire concentrating seat 9 and a wire winch 10 which are longitudinally arranged on the supporting wall panel 2 in sequence. One end of the wire is passed around the outside of the wire concentrating seat 9 and fixed on the output end of the wire winch 10. The wire concentrating seat 9 includes a support frame fixed on the supporting wall panel 2 and a rotating drum rotatably installed in the support frame. After the wire bobbin is installed or replaced, one end of the wire on it is passed through the wire ring 44, the wire bundle 6, the wire bundle ring 7, and the bundle coil 85 from bottom to top in sequence, and is wound around the rotating drum for several turns, and finally tied to the output end of the wire winch 10, so that the threading work of the wire can be completed, and the positions of the wire bundle 6 and the wire bundle ring 7 in the vertical direction are consistent and are located on the symmetrical plane of the axis of the slide rod 42, at the same time. The positions of the two in the thickness direction of the supporting wall panel 2 are staggered, which can maintain a certain tension on the wire and avoid the problem of loosening. After the wire passes through the wire tie ring 7, its path will bend toward the wire concentration seat. When passing through the bundle coil 85 in the middle, the bending angle of its path will change accordingly with the change of the winding speed of the wire winch 10 and the change of the size of the wound wire ball. In the process, the tension on the wire will also change accordingly. The change in tension will cause the rocker arm to swing, and the stress caused by the tension change on the wire will be buffered by the elastic deformation of the torsion spring 83, and the tension on the wire will be buffered again, so as to avoid the secondary large-scale shaking of the wire transmitted between the wire tie ring 7 and the wire concentration seat 9, and further improve the stability of the wire transmission.
[0071] The above description is only the preferred embodiment of the utility model, and the parts not described in the utility model can be implemented by adopting or drawing on existing technologies. Of course, the above description is not a limitation of the utility model, and the utility model is not limited to the above examples. The changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the utility model should also fall within the protection scope of the utility model.
