Description

Technical Field

[0001] The utility model relates to the technical field of material transportation, in particular to a single-roll automatic unwinding device. Background Art

[0002] Fiberglass cloth is usually collected in rolls for easy transportation. When used, the rolled cloth is gradually released and processed. The single-roll unloading device is used to release the rolled cloth. In the prior art, since the cloth is flexible, it will be affected by many factors when it is released. The tension of the fiberglass cloth will change, damaging the cloth surface. At the same time, the cloth surface will also deviate up and down during operation, affecting the subsequent material collection. Utility Model Content

[0003] In view of the above problems, the purpose of the utility model is to provide a single-roll automatic unwinding device which can automatically adjust the tension and correct the deviation.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is as follows: a single-roll automatic unwinding device, comprising a frame, on which are provided a material roller, a tension adjustment roller, a correction roller and a guide roller, the tension adjustment roller being mounted on a tension adjustment frame, the middle part of the tension adjustment frame being hinged to the frame, an adjusting cylinder being provided at the lower part of the tension adjustment frame, and the tension adjustment frame being able to rotate along the middle part when driven by the adjusting cylinder.

[0005] In the above technical solution, a deviation correction sensor is provided on the guide roller frame of the guide roller.

[0006] In the above technical solution, height adjustment mechanisms are provided on both sides of the deviation-correcting roller.

[0007] In the above technical solution, the height adjustment mechanism is a screw assembly.

[0008] In the above technical solution, a hinge shaft is provided in the middle of the tension adjustment frame, and both ends of the hinge shaft are fixedly connected to the frame.

[0009] In the above technical solution, an anti-falling platform is provided on the frame below the material roller.

[0010] In the above technical solution, the material roller is mounted on a material roller frame, and a moving mechanism is provided at the lower part of the material roller frame. The moving mechanism includes a roller arranged at the lower part of the material roller frame and a track arranged on the frame.

[0011] To sum up, the technical solution of the utility model has the following beneficial effects compared with the traditional technical means: the utility model adds a tension adjusting roller and a deviation correction roller on the basis of the existing single-roll unwinding mechanism, and sets guide rollers on both sides accordingly. During use, the cylinder is adjusted to control the rotation of the tension adjusting frame to drive the displacement of the tension adjusting roller, thereby adjusting the surface tension of the cloth and ensuring the quality of the cloth surface. At the same time, the position of the entire frame can be adjusted according to the data of the deviation correction sensor to achieve deviation correction, so that the glass fiber cloth is always kept on the same straight line and the unwinding is stable.
