It is an auxiliary machine for wire extrusion machines and stranding machines. It can ensure that the wires are tightly arranged during the winding process, thereby improving the neatness and quality of the wires.
[0003] Some compact rewinding machines used for aluminum wire rewinding cannot adjust the tension during aluminum wire winding, which can easily lead to insufficient winding tension and cause the coiled wire on the take-up reel to become loose. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A tensioning structure for a tight rewinding machine includes a tight rewinding machine body. A tensioning mechanism is provided on one side of the tight rewinding machine body. The tensioning mechanism includes a support base. One side of the support base is connected to the tight rewinding machine body. Fixed seats are symmetrically arranged on both sides of the top of the support base. A first fixed shaft assembly and a second fixed shaft assembly are slidably arranged between the two fixed seats at equal distances. A tensioning roller body is movably sleeved on the outer wall of the first fixed shaft. Multiple adsorption blocks are equidistantly clamped on the outer wall of the tensioning roller body.

[0008] Furthermore, in a preferred configuration, both the first fixed shaft assembly and the second fixed shaft assembly include two fixed sliders, with symmetrically mounted extending protrusions on both sides of the fixed sliders, and the fixed sliders are limited and slidably disposed within the fixed base, with a fixed shaft connecting the two fixed sliders.
[0009] Furthermore, in a preferred configuration, a groove is provided in the fixed seat at the fixed slider, a limiting groove is provided in the fixed seat at the extending protrusion, and a through groove is provided in the fixed seat at the fixed shaft.
[0010] In addition, a preferred structure is that a limiting guide rod is fixedly installed in the middle of the limiting groove, and a through hole is opened in the fixed slider at the limiting guide rod.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] Reference Figure 1-3A tensioning structure for a tight rewinding machine includes a tight rewinding machine body 1. A tensioning mechanism is provided on one side of the tight rewinding machine body 1. The tensioning mechanism includes a support base 2, one side of which is connected to the tight rewinding machine body 1. Fixed seats 21 are symmetrically arranged on both sides of the top of the support base 2. A first fixed shaft assembly 7-1 and a second fixed shaft assembly 7-2 are slidably arranged at equal distances between the two fixed seats 21. A tensioning roller body 3 is movably sleeved on the outer wall of the first fixed shaft 7-1. A plurality of suction blocks 31 are equidistantly clamped on the outer wall of the tensioning roller body 3. The outer wall of the second fixed shaft assembly 7-2 is fixedly fitted with a magnetic fixing roller 4, and the two sides of the top of the first fixed shaft assembly 7-1 are symmetrically installed with fixing screws 6. One end of the outer wall of the fixing screw 6 passes through the fixing seat 21 and is rotatably installed with two fastening nuts. The specific structure and working method of the tight rewinding machine body 1 are all existing technologies that have been disclosed on the market and are not the main technical problems to be solved in this technical solution. Therefore, they will not be described in detail in this utility model. This tensioning mechanism is suitable for rewinding and winding non-magnetic metal wires such as aluminum wire.
[0021] Furthermore, cavities are provided on both sides of the first fixed shaft assembly 7-1, and a hydraulic rod assembly 9 is vertically arranged downward in the cavity. The top end of the hydraulic rod assembly 9 extends out of the first fixed shaft assembly 7-1 and connects with the second fixed shaft assembly 7-2.
[0022] Meanwhile, both the first fixed shaft assembly 7-1 and the second fixed shaft assembly 7-2 include two fixed sliders 71. Extending protrusions 72 are symmetrically installed on both sides of the fixed sliders 71, and the fixed sliders 71 are limited and slidably disposed in the fixed seat 21. A fixed shaft connects the two fixed sliders 71.
[0023] Meanwhile, a sliding groove is provided in the fixed seat 21 at the fixed slider 71, and a limiting sliding groove is provided in the fixed seat 21 at the extension protrusion 72, and a through sliding groove is provided in the fixed seat 21 at the fixed shaft.
[0024] Furthermore, a limiting guide rod 8 is fixedly installed in the middle of the limiting slide groove, and a through hole is opened in the fixed slider 71 at the limiting guide rod 8.
[0025] Furthermore, an extension seat is installed above the two fixed seats 21 on the side away from the main body 1 of the tight rewinding machine. A guide roller assembly 5 is provided on one side between the two extension seats. The guide roller assembly 5 includes a limiting shaft. Both sides of the limiting shaft are connected to the extension seats. The guide roller body is movably sleeved on the outer wall of the limiting shaft.
[0026] Furthermore, one end of the fixing screw 6 extends through the fixing seat 21 and is fixedly installed with a handle. A through hole is provided in the fixing seat 21 at the fixing screw 6, and the diameter of the through hole is larger than the diameter of the fixing screw 6.
[0027] In this embodiment, the guide roller assembly 5 guides the wire to be rewound. The wire is passed through the top of the guide roller assembly 5 and then transmitted to the bottom of the tension roller body 3, finally connecting to the tight rewinding machine body 1. The fixing screw 6 moves up and down and is tightened with a fixing nut, thereby adjusting the height of the first fixed shaft assembly 7-1 and the height of the tension roller body 3, thus tensioning the wire to be rewound. When the tension roller body 3 is in normal use, the hydraulic rod assembly 9 is opened by control, so that the top end of the hydraulic rod assembly 9 extends, moving the second fixed shaft assembly 7-2 away from the first fixed shaft assembly 7-1.
[0028] Meanwhile, when a wire breaks during the rewinding process of the aluminum wire, the hydraulic rod assembly 9 is shut down, causing the top extension end of the hydraulic rod assembly 9 to retract, bringing the second fixed shaft assembly 7-2 closer to the first fixed shaft assembly 7-1, and magnetically connecting the adsorption block 31 with the magnetic fixed roller 4, thereby clamping the wire to be rewound and preventing it from shrinking or loosening.
[0029] In this utility model, the coordinated arrangement of the first fixed shaft assembly 7-1, the tension roller body 3, the second fixed shaft assembly 7-2, and the fixed screw 6 facilitates the tensioning of the aluminum wire when the tight rewinding machine body 1 performs rewinding and winding processing, and clamps the wire when a wire breaks during the rewinding and winding process to prevent the wire from shrinking or loosening.
[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. 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.
