DETAILED DESCRIPTION

[0027] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. The embodiments are only used to explain the present invention and do not limit the scope of protection of the present invention.

[0028] Example

[0029] like Figures 1 to 11 As shown, this embodiment provides a multifunctional wire pay-off equipment, including a frame 1, a front roller 2, a rear roller 3, a front active mechanism 4, and a wire reel 5; wherein the front roller 2, the rear roller 3, the front active mechanism 4 and the wire reel 5 constitute a pay-off unit.

[0030] Please refer to Figure 1 As shown, a multifunctional wire pay-out device of this embodiment has five pay-out units arranged on the frame 1. The overall area is relatively wide, and the overall height is relatively low, with the center of gravity at a low position, so it will not fall over during the construction process.

[0031] Refer again Figure 3 As shown, the frame 1 is provided with body side panels 101 on both sides of each pay-off unit; two adjacent pay-off units share one body side panel 101; the body side panels 101 are arranged in the front-to-back direction, the front roller 2 is arranged at the front end of the body side panel 101 near the top side, the rear roller is arranged at the rear end of the body side panel 101, and the body side panel is further provided with a fourth connecting rod 102 at the front end near the bottom side; the front roller 2 and the rear roller 3 are arranged in parallel, and the shortest distance (non-center distance) between the two rollers is slightly smaller than the diameter of the wire drum, so that the wire drum can be erected on the two rollers and the wire drum is tangent to the front roller and the rear roller. ; The front roller 2 is mounted on the first connecting rod 201 and can rotate freely around the first connecting rod 201, and the rear roller 3 is mounted on the second connecting rod 301 and can rotate freely around the second connecting rod 201; the two ends of the first connecting rod 201 are respectively connected to the two machine side panels 101; the two ends of the second connecting rod 301 are also respectively connected to the two machine side panels 101; when multiple pay-off units form a whole, the first connecting rod 201, the second connecting rod 301, and the fourth connecting rod 102 connect the multiple machine side panels 101 into a whole; at this time, when the front roller 2 and the rear roller 3 are placed in the wire drum, the pay-off operation can be carried out.

[0032] Refer again Figure 3 and Figure 4 In order to make the pay-off equipment more convenient to use, a front active mechanism 4 is designed, which includes two front active side panels 401; the front active side panels are tilted in the front upper and rear lower directions; the front active side panels 401 are located at the rear position of the top side and are provided with a first hole 414; the front active side panels 401 are sleeved on the first connecting rod 201 through the first hole 414, and the front active side panels 401 are located between the machine body side panels 101 and the front roller 2.

[0033] Refer again Figures 3 to 6In order to prevent the wire 6 from being too loose when the wire is released, a wire passing roller 402 and a wire pressing plate fixing roller 403 are provided between the two front active side plates 401; the wire pressing plate fixing roller 403 is sleeved on the first shaft 405, and the wire passing roller 402 is sleeved on the second shaft 404; the two ends of the first shaft 405 are fixed to the two front active side plates 401 respectively, and the fixed position is located at the rear position of the bottom side of the front active side plate 401; the two ends of the second shaft 404 are fixed to the two front active side plates 401 respectively, and the fixed position is located at the upper position of the bottom side of the front active side plate 401; a wire pressing plate is fixed on the wire pressing plate fixing roller 403 406; the wire pressing plate 406 is located below the wire passing roller 402, and the rear end of the wire pressing plate 406 is fixed to the wire pressing plate fixed roller 403; the bottom end of the front active side plate 401 is below the wire pressing plate and close to the wire pressing plate fixed roller 403 and is also provided with a fixed block 416; torsion springs 409 are also provided at both ends of the wire pressing plate fixed roller 403; one end of the torsion spring 409 is against the bottom side of the wire pressing plate, and the other end is against the top side of the fixed block 416, and the torsion spring 409 is used to provide the wire pressing plate 406 with a pressing force on the wire 6, thereby making the wire pressing plate 406 cooperate with the wire passing roller 402 to provide tensioning force for the wire 6 between the two.

[0034] In order to prevent the wire from running off, a front limit frame 407 and a rear limit frame 408 are respectively provided on the front and rear sides of the wire pressing plate 406; the wire passing roller 402 is located in the area between the rear limit frame 408 and the front limit frame 407; the front limit frame 407 and the rear limit frame 408 constitute a wire passing channel and limit it in the circumferential direction, which can effectively prevent the wire from running off. For the specific structure, please refer to Figures 4 to 6 As shown; after the wire reel is placed on the front roller and the rear roller, the wire out of the wire reel is led out through the rear limit frame 408, the gap between the wire pressing plate and the wire passing roller, and the front limit frame 407. It can be pulled as needed, which can effectively avoid the wire clamping phenomenon caused by the deviation of the wire.

[0035] Refer again Figures 2 to 5As shown, in order to prevent the wire reel from rotating too fast or sliding in actual use, a brake block 415 is provided near the middle of the rear side of the front active side plate 401. The brake block 415 cooperates with the wire reel 5 to provide a braking function for the wire reel 5. A multifunctional wire unwinding device of this embodiment also adopts the following design: the front active mechanism 4 also includes a third connecting rod 410; the two ends of the third connecting rod 410 are respectively fixed to the two front active side plates 401, and the fixed position is located at the front position of the top side of the front active side plate 401; the front active side plate 401 is located below the third connecting rod 410 and is also provided with a connecting column 411; a connecting piece 413 is sleeved on the fourth connecting rod 102; the front active mechanism 4 also includes a tension spring 412; one end of the tension spring 412 is connected to the connecting column 411, and the other end is connected to the connecting column 411. The connecting piece 413 is connected; since the front active mechanism is sleeved on the first connecting rod 201, it can rotate with the first connecting rod 201 as the axis. When the tension spring 412 connects the front end of the front active mechanism with the frame (specifically the fourth connecting rod of the frame), the front active mechanism will be deflected, causing the rear end of the front active mechanism to tilt upward, thereby causing the brake block 415 to contact the wire drum 5. Since the front end of the front active mechanism and the frame are connected by the tension spring 415, the rear end of the front active mechanism will swing within a certain range, and the wire will be in a stable state. During the pay-out process, when the wire passes between the wire pressing plate and the wire passing roller, the wire pressing plate clamps the wire with the wire passing roller under the action of the torsion spring, and friction is generated between the wire and the wire pressing plate. This friction will overcome the action of the tension spring and deflect the rear end of the front active mechanism downward, thereby separating the brake block on the rear side of the front active side plate from the wire drum, so that the wire drum can rotate freely to feed the wire; and when the wire drum is transported too fast, that is, the rotation speed of the wire drum is faster than the pay-out speed, the outgoing wire will be loosened, and the rear end of the front active mechanism will no longer be pulled downward to deflect, and the rear end of the front active mechanism will be in the front Under the action of the tension spring at the front end of the active mechanism, it tilts upward again, causing the brake block to contact the wire drum to reduce the rotation speed of the wire drum to match the required pay-off speed. Then, under the action of the wire pressing plate, torsion spring, wire roller, tension spring and brake block, the rotation speed of the wire drum is dynamically controlled according to the required pay-off speed to make the pay-off more stable. When the pay-off stops, the brake design mentioned above will cause the brake block to quickly brake the wire drum when the pay-off stops, preventing the wire drum from continuing to supply a small section of wire under the action of inertia, causing the wire to slack.

[0036] Refer again Figure 4 、 Figures 7 to 9As shown, in order to make the wire coil more securely fixed on the wire drum and thus make the wire output more stable, the wire drum of a multifunctional wire unwinding device of this embodiment adopts the design of an expansion core shaft; specifically, the wire drum 5 includes a first circular plate 501 on the left and a second circular plate 508 on the right; the expansion core shaft includes three expansion and contraction modules; the expansion and contraction module includes a slide 512; a radial guide groove 511 is provided on the first circular plate 501; the guide groove 511 is correspondingly assembled with the slide 512 of the expansion and contraction module, so that the slide 512 can only slide radially along the guide groove 511; the slide 512 is The guide groove 511 is provided with an inclined surface that gradually decreases from left to right, and the guide groove is also designed in the same way, so that the slide 512 can slide radially along the guide groove 511 and cannot move left or right after installation; the slide 512 is fixed with an inner support portion 502; the outer surface of the inner support portion 502 of the three expansion and contraction modules constitutes a generally circular support surface for supporting the wire coil 6; the inner surface of the inner support portion 502 is fixed with an expansion and contraction block 503; the inner surface of the expansion and contraction block 503 is set as an expansion and contraction inclined surface 513; the expansion and contraction inclined surfaces 513 of the multiple expansion and contraction modules constitute an expansion and contraction guide cone cavity; the expansion and contraction guide cone cavity has a diameter from left to right Gradually increases; the expansion and contraction module also includes an expansion head 505; the left side of the expansion head 505 cooperates with the expansion and contraction guide cone cavity, which is used to make the three expansion and contraction modules move radially outward along their respective guide grooves 511 when the expansion head moves toward the small diameter end of the guide cone cavity (moves to the left); a screw 507 is also fixed at the center of the first circular plate 501, and the side of the screw near the right end is provided with an external thread, and the rest is a straight rod; a threaded hole 510 is provided at the center of the second circular plate 508; the screw 507 passes through the expansion core shaft and the expansion head 505 and is threadedly connected to the second circular plate 508 through the threaded hole 510 The expansion head 505 is further provided with a groove 509 on one side close to the second circular plate 508; a pressure spring 506 is further sleeved on the area of ​​the screw 507 between the expansion head 505 and the second circular plate 508; one end of the pressure spring 506 rests on the second circular plate 508 and the other end rests in the groove 509, so as to provide thrust for the expansion head 505 and thereby provide outward expansion force for the multiple expansion and contraction modules; a second hole 514 is further provided on the side of the expansion and contraction block 503; a module tension spring 504 is commonly passed through the second holes 514 of the multiple expansion and contraction modules, so as to provide centripetal contraction force for the multiple expansion and contraction modules.

[0037] When installing or removing the wire coil of the wire reel, the second circular plate 508 is unscrewed from the screw 507 of the first circular plate 501. At this time, the pressure spring 506 is in a relaxed state. Under the tension of the module tension spring 504, the three expansion and contraction modules move radially and centripetally along their respective guide grooves 511 and move to the end of the guide groove close to the center of the circular plate. At this time, due to the reduction in the diameter of the supporting surface formed by the expansion and contraction modules, the wire coil can be easily removed from the expansion and contraction modules, or can be easily installed on the expansion and contraction modules. After the wire coil is installed on the expansion and contraction modules, the second circular plate 508 is screwed back on the screw 507 and locked. In this process, the pressure spring 506 is in a relaxed state. Under the tension of the module tension spring 504, the three expansion and contraction modules move radially and centripetally along their respective guide grooves 511 and move to the end of the guide groove close to the center of the circular plate. During the reinstallation of the second circular plate 508, the spring 506 is compressed, and the pressure spring 506 pushes the expansion head to the left. After overcoming the tension of the module tension spring 504 (this force is relatively small and only plays a role in contraction and reset), the three expansion and contraction modules, under the action of the expansion head, move radially away from the center along their respective guide grooves 511 and expand, thereby effectively expanding and supporting the core of the wire coil, so that the core of the wire coil does not relax, and as the number of coils of the wire coil decreases and the core tends to loosen, the three expansion and contraction modules will continue to expand under the action of the pressure spring, so that the three expansion and contraction modules always provide strong support for the core of the wire coil.

[0038] Please refer to Figure 1 、 Figure 10 and Figure 11 As shown, in a multifunctional wire-releasing device of this embodiment, the frame 1 also includes a frame base; the frame base includes a side seat 103; the side seat 103 has two front and rear support legs; the two side seats 103 are connected and fixed by a bottom beam 107; the side seat 103 is fixed with an insertion rod 104 that tilts from bottom to top and from front to back. In a multifunctional wire-releasing device of this embodiment, five wire-releasing units and six body side panels 101 are used to form a whole through a first connecting rod 201, a second connecting rod 301, and a fourth connecting rod 102; wherein, the outer side surfaces of the body side panels on both sides of the whole structure are also fixed with mounting blocks 105, and the bottom side surfaces of the mounting blocks 105 are provided with slots that match the insertion rods 104. During installation, the whole structure is installed on the insertion rods 104 through the slots; in order to strengthen the strength of the frame base, a reinforcing plate 106 is also provided between the side seat 103 and the insertion rod 104.
