AI Technical Summary
Existing technologies are difficult to effectively tension large-diameter steel bars, and traditional magnetic or elastic arm methods require significant resources or space, resulting in insufficient reliability.
A mechanical tensioning mechanism is adopted, which includes a mounting plate, a guide wheel, a damping component, and a preload spring. The mechanical preload of the wire is achieved through the cooperation of the guide wheel and the preload spring, and the tension is controlled by adjusting the preload force using a pressure adjusting nut.
It improves the reliability of wire tensioning, reduces resource consumption and space occupation, and provides a more stable tension force.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of metal processing technology and relates to a tensioning mechanism for bundling wire. Background Technology
[0002] For iron wires or bars with larger diameters, bundling is often used for packaging, while smaller diameter iron wires are packaged by winding. When winding and packaging, the wire needs to be tensioned to ensure that the winding is tight and orderly. The tensioning of steel bars with a diameter of 0.1 to 0.5 cm is different from that of steel wires with smaller diameters. Steel wires can be tensioned using magnetic force or elastic arms, but steel bars have greater rigidity and greater deformation recovery force. When using magnetic force or elastic arms for tensioning, the magnetic force must be large enough or the elastic arm must be long enough. Otherwise, it is difficult to ensure orderly traction of the steel bars and provide a stable tension force. Utility Model Content
[0003] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a tensioning mechanism for wire packing. The technical problem to be solved by this invention is how to improve the reliability of wire tensioning.
[0004] The objective of this utility model can be achieved through the following technical solution: a tensioning mechanism for bundling wire, characterized in that it includes a mounting plate, at least one guide wheel rotatably connected to the mounting plate, and a damping assembly corresponding to the guide wheel. The damping assembly includes a toothed ring disposed on the guide wheel. A guide rod is fixedly disposed on the mounting plate. A sleeve is slidably connected to the guide rod via a spline. The sleeve has a rack that meshes with the toothed ring. A preload spring is sleeved on the guide rod and connected between the sleeve and the mounting plate.
[0005] Furthermore, there are two guide wheels.
[0006] The wire is sequentially pulled through the upper part of the first guide wheel and the lower part of the second guide wheel. The two damping components are symmetrically distributed and act on the two gear rings respectively.
[0007] Furthermore, the guide rod is threaded with adjusting nuts located at the outer end of the sleeve and the outer end of the preload spring, respectively. The adjusting nuts can adjust the preload force of the preload spring, thereby adjusting the tension of the wire traction.
[0008] As the wire moves in the traction direction, the guide wheel rotates synchronously with the wire under traction, causing the rack to retract. Simultaneously, the rotation of the guide wheel compresses the preload spring in the sleeve, bringing the rack to a state where it is about to disengage from the gear ring, while maintaining the preload spring in a compressed state. Thus, the rotation of the guide wheel is subject to a certain damping force, thereby achieving tensioning of the wire traction. This tensioning method is mechanical preload, which offers higher reliability and occupies less space compared to traditional magnetic and elastic arms. Attached Figure Description

[0011] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0012] like Figure 1 The tensioning mechanism shown is used for traction during wire winding and packaging. It includes a mounting plate 1, two guide wheels 2 rotatably connected to the mounting plate 1, and damping components corresponding to the guide wheels. The damping components include toothed rings 3 set on the guide wheels 2. A guide rod 4 is fixedly set on the mounting plate 1. A sleeve 5 is slidably connected to the guide rod 4 via a spline. The sleeve 5 has a rack 6 that meshes with the toothed rings 3. A preload spring 7 is sleeved on the guide rod 4 and connected between the sleeve 5 and the mounting plate 1.
[0013] The wire is sequentially pulled through the upper part of the first guide wheel 2 and the lower part of the second guide wheel 2. The two damping components are symmetrically distributed and act on the two toothed rings 3 respectively.
[0014] The guide rod 4 is threaded with adjusting nuts 8 located at the outer ends of the sleeve 5 and the preload spring 7, respectively. The adjusting nuts 8 can adjust the preload force of the preload spring 7, thereby adjusting the tension of the wire traction.
[0015] When the wire moves in the traction direction, the guide wheel 2 is pulled and rotates synchronously with the wire, causing the rack 6 to retract. Simultaneously, the rotation of the guide wheel 2 drives the sleeve 5 to compress the preload spring 7, bringing the rack 6 to a state where it is about to disengage from the gear ring 3, while maintaining the preload spring 7 in a compressed state. Thus, the rotation of the guide wheel 2 is subject to a certain damping force, thereby achieving tensioning of the wire traction. This tensioning method is a mechanical preload, which has higher reliability and occupies less space compared to traditional magnetic and elastic arms.
[0016] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
