Description

Technical Field

[0001] This utility model relates to the field of tension adjustment technology, and in particular to a tension swing arm angle adjustment device. Background Technology

[0002] Tension adjustment devices are often used in the production of metal foils, strips, and other similar products. These devices keep these flexible materials in a tensioned state to facilitate subsequent processing. However, due to varying on-site environments during production, the angle of the tension rollers needs to be adjusted to adapt to these environments. However, some tension rollers on the market are directly mounted on the rotating shaft, a design that makes angle adjustment inconvenient and cumbersome.

[0003] For example, Chinese patent application number CN202420113487.3 discloses a tension swing arm device for a reciprocating winding machine. Specifically, it discloses that "the tension swing arm is rotatably mounted on a support base, a guide wheel can be fixedly mounted on one end of the tension swing arm, a counterweight is slidably connected to the other end of the tension swing arm, the output shaft of the drive cylinder is connected to the support base, and a potentiometer is connected to the tension swing arm to detect changes in its rotation angle. When the tension of the roll material changes, the tension swing arm can swing up and down accordingly, and the drive cylinder can output torque to the tension swing arm to adjust its tension." This type of tension swing arm is directly mounted on the rotating shaft. If further adjustment of the tension roller angle is required, the tension swing arm needs to be disassembled and then adjusted, which is very cumbersome.

[0004] For example, Chinese patent application CN201821932582.7 discloses a tension roller for an aluminum foil coating machine, comprising a frame, a rotating shaft with both ends mounted on the frame, a tension roller, and a tension cylinder. The key feature is that a pair of swing arms are mounted on the rotating shaft, the tension roller is positioned between the swing arms, and the tension cylinder is positioned between the swing arms and the frame. Two pairs of limiting seats are mounted on the frame, located on either side of the two pairs of swing arms. Each limiting seat consists of a steel shaft and a rubber sleeve covering the steel shaft. Since the swing arms are directly mounted on the rotating shaft, further adjustment of the tension roller angle requires disassembling the tension swing arms before adjustment, which is cumbersome.

A tuning roller 45 is disposed on the tension swing arm 43, and the tuning roller 45 can tension the material. The rotating shaft mechanism 10, the drive mechanism 20, and the angle monitoring mechanism 30 are disposed on a mounting frame 16. The mounting plate 40 is mounted on the rotating shaft 11, and several adjustment holes 42 are set at equal angles on the mounting plate 40. The first fastener 47 is a screw or bolt. The tension swing arm 43 is provided with a second mounting hole 44.
