Description

Technical Field

[0001] This utility model relates to the field of wire winding technology, and in particular to a wire tensioning mechanism. Background Technology

[0002] Copper wire is a thin, long wire made of copper, widely used in various fields, especially in the electrical, electronic, communications, construction, and manufacturing industries. Copper wire has excellent electrical and thermal conductivity and corrosion resistance, thus finding wide application in many situations. During the production process, copper wire needs to be wound, and this winding process requires adjustment using a tensioning mechanism.

[0003] While existing wire tensioning mechanisms can adjust the tension of copper wires during use, the tension on the copper wires remains relatively stable during winding, but changes occur after the tension is adjusted. This alters the tensile force on the copper wires, making them prone to breakage due to increased tensile force. Utility Model Content

[0004] The main purpose of this invention is to provide a fine wire tensioning mechanism.

[0005] The objective of this utility model can be achieved by adopting the following technical solution:

[0006] A thin wire tensioning mechanism includes a bracket with symmetrically arranged slots on the bracket. A wire threading hole is located outside each slot on the bracket. An adjusting rod is positioned below the slot, and an adjusting mechanism is connected to the outside of the adjusting rod. A protective mechanism is installed at the back of the bracket. The protective mechanism includes a fixing plate fixedly connected to the bracket. A base is installed on one side of the fixing plate, and an elastic connecting rod is connected to one side of the base. One end of the elastic connecting rod is fixed to a mounting bracket, and a roller is rotatably connected within the mounting bracket.

[0007] Preferably, the threading hole extends through the bracket, and a wire guard is fixed inside the threading hole.

[0008] Preferably, the adjusting rod passes through the slot and is located below the threading hole.

[0009] Preferably, the adjusting mechanism includes a cylinder, a piston rod, and a mounting base, with the cylinder fixed to one side of the bracket.

[0010] Preferably, the piston rod is slidably connected to the cylinder, and one end of the piston rod is connected to the mounting base.

[0011] Preferably, the number of adjusting rods is the same as the number of empty slots, and the adjusting rods are fixedly connected to the mounting base.

[0012] Preferably, the elastic connecting rod has an inclined structure, and the initial position of the roller is on the same horizontal plane as the threading hole.

[0013] The beneficial effects of this technology are:

[0014] By setting up a protective mechanism, when the copper wire is wound, the mounting frame and rollers are installed on one side of the support through elastic connecting rods, base and fixing plate. During the winding process, the copper wire passes through the outside of the rollers for winding. When the tension of the copper wire is adjusted, the tensile force it receives increases. At this time, the copper wire drives the elastic connecting rod through the rollers and mounting frame to bend under the force, thereby relieving the force and preventing the copper wire from breaking due to the increased tensile force after the tension is adjusted.

[0020] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0021] like Figures 1-3As shown, the thin wire tensioning mechanism provided in this embodiment includes a bracket 1. The bracket 1 has symmetrically arranged slots 2, which facilitate the adjustment of the copper wire tension by an adjusting rod 4. A wire-passing hole 3 is provided on the bracket 1 outside the slots 2, through which the copper wire passes. An adjusting rod 4 is located below the slots 2, allowing adjustment of the copper wire tension. An adjusting mechanism 5 is connected to the outside of the adjusting rod 4. A protective mechanism 6 is installed at the back end of the bracket 1, including a fixing mechanism fixedly connected to the bracket 1. Plate 601, fixed plate 601 can support base 602. Base 602 is installed on one side of fixed plate 601. Elastic connecting rod 603 is connected to fixed plate 601 through base. Elastic connecting rod 603 is connected to one side of base 602. Elastic connecting rod 603 can bend after being subjected to force, thereby relieving force. One end of elastic connecting rod 603 is fixed with mounting bracket 604. Mounting bracket 604 can support roller 605. Roller 605 is rotatably connected inside mounting bracket 604. Roller 605 can guide copper wire.

[0022] like Figures 1-2 As shown, the wire hole 3 passes through the bracket 1, and a wire protection sleeve 7 is fixed inside the wire hole 3, which facilitates the copper wire to pass through the wire hole 3 and through the bracket 1. The wire protection sleeve 7 can protect the copper wire and prevent the copper wire from rubbing against the bracket 1.

[0023] like Figures 1-2 As shown, the adjusting rod 4 passes through the slot 2 and is located below the wire hole 3, which can prevent the adjusting rod 4 from sliding down due to gravity and pressing the copper wire after the cylinder 501 is cut off.

[0024] like Figures 1-2 As shown, the adjustment mechanism 5 includes a cylinder 501, a piston rod 502, and a mounting base 503. The cylinder 501 is fixed to one side of the bracket 1, which facilitates the adjustment of the height of the adjustment rod 4 through the adjustment mechanism 5.

[0025] like Figures 1-2 As shown, the piston rod 502 is slidably connected to the cylinder 501, and one end of the piston rod 502 is connected to the mounting base 503, so that the cylinder 501 can drive the mounting base 503 to rise and fall through the piston rod 502.

[0026] like Figures 1-2 As shown, the number of adjusting rods 4 is the same as the number of empty slots 2, and the adjusting rods 4 are fixedly connected to the mounting base 503. The mounting base 503 can drive the adjusting rods 4 to adjust the tightness of the copper wire in the empty slot 2.

[0027] like Figures 1-3 As shown, the elastic connecting rod 603 has an inclined structure, and the initial position of the roller 605 is on the same horizontal plane as the wire hole 3, which facilitates the copper wire to be wound on the outside of the roller 605 and ensures the normal winding of the copper wire.

[0028] The working principle of this device is as follows: In actual use, the copper wire passes through the outlet hole, through the bracket 1 and the empty slot 2, and one end of the copper wire is connected to the external winding mechanism via the roller 605. During the winding process of the copper wire, the cylinder 501 in the adjusting mechanism 5 can drive the mounting base 503 to move through the piston rod 502. The mounting base 503 drives the adjusting rod 4 to move in the empty slot 2 to adjust the tension of the copper wire. During the adjustment process, the tension of the copper wire changes, thereby changing the tensile force it receives. At this time, the copper wire bends due to the force on the elastic connecting rod 603 driven by the roller 605 and the mounting bracket 604, thereby relieving the force and preventing the copper wire from breaking due to the increased tensile force after the tension adjustment.

[0029] The above are merely further embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed by this utility model, based on the technical solution and concept of this utility model, shall fall within the protection scope of this utility model.
