Abstract

The utility model discloses a TPU film rolling-out pressure monitoring and adjusting assembly, and belongs to the technical field of TPU film manufacturing equipment. By arranging the adjusting roller, the adjusting roller is pressed on the surface of a thin film in the rolling-out process of the thin film, the adjusting roller bears pressure to extrude the spring to be pressed, and therefore the pressure applied to the thin film by the adjusting roller can be read in real time through the dial indicator, and the thin film stretching tension can be achieved by controlling the rotating speed of the rotating shaft at the rear end; the stretching of the thin film is monitored in real time, so that the condition of non-uniform stretching is avoided.

Description

Technical Field

[0001] The utility model belongs to the technical field of TPU film manufacturing equipment, and in particular relates to a TPU film rolling-out pressure monitoring and adjustment component. Background Art

[0002] The newly extruded TPU film generally needs to be stretched along the long direction of the film (also known as the longitudinal direction). The physical properties of the film will be improved after longitudinal stretching.

[0003] Most of the existing TPU film stretching devices use the speed difference of the rollers to pull the film at the far end during the TPU film extrusion process, so that the physical properties of the unhardened film are improved by stretching in the longitudinal direction, and the thickness can be adjusted by stretching the film at the same time. However, during the stretching process of the film, it is difficult for the existing stretching devices to directly monitor the stretching force of the film, which leads to uneven stretching of the film. Summary of the Invention

[0004] The utility model mainly solves the technical problems existing in the above-mentioned prior art and provides a TPU film rolling-out pressure monitoring and adjustment component.

[0005] The above technical problems of the present invention are mainly solved by the following technical solutions: A TPU film unwinding pressure monitoring and adjustment assembly includes an adjustment roller and a shaft seat assembly, the adjustment roller includes a shaft neck at both ends, and a monitoring ring is provided on the shaft neck. The monitoring ring is fixedly connected to the adjustment roller and the two are coaxially arranged. The shaft seat assembly includes a mounting seat and a supporting sliding seat. The outer end of the shaft neck of the adjustment roller passes through the supporting sliding seat and is rotatably connected to the supporting sliding seat. The supporting sliding seat is slidably connected to the mounting seat. A contact ring is provided at the front end of the mounting seat, and a guide column is provided at the rear end of the mounting seat. The contact ring and the guide column are coaxially arranged. An adjustment handle is provided at the front end of the mounting seat, the adjustment handle is threadedly connected to the mounting seat, and the rear end of the adjustment handle abuts against the contact ring of the mounting seat. A spring is sleeved on the guide column, the front end of the spring abuts against the supporting sliding seat, and the rear end of the spring abuts against the mounting seat. A mounting bracket is provided on the side of the mounting seat, and a dial indicator is provided on the mounting bracket. The contact head of the dial indicator abuts against the surface of the monitoring ring.

[0006] Preferably, the upper and lower surfaces of the supporting sliding seat are provided with sliding bosses.

[0007] Preferably, the mounting seat is provided with a sliding groove that cooperates with the boss.

[0008] The utility model has the beneficial effects: by arranging the adjustment roller, the adjustment roller is pressed against the surface of the film during the unwinding process, the adjustment roller receives pressure and the extrusion spring is compressed, so that the pressure applied by the adjustment roller on the film can be read in real time through a dial indicator, so that the tension applied to the film can be achieved by controlling the rotation speed of the rear end rotating shaft, and the stretching of the film can be monitored in real time to avoid uneven stretching.
