[0001] The utility model belongs to the technical field of tensioning, in particular to a tensioner used for processing PTFE membrane materials. Background Art

[0002] Membrane structure is a new type of building structure that can beautify, block rain, and provide sunshade. Membrane material is an important component of membrane structure, and membrane material is also called membrane cloth. PTFE membrane material is a membrane material that is widely used in the construction field. PTFE membrane material is a coated fabric composed of a glass fiber base material and a PTFE emulsion coating. It has high self-cleaning, aging resistance, fire resistance and other properties.

[0003] In the existing tensioner technology for PTFE membrane processing, the membrane material often needs to be manually tensioned during processing. However, the tensioning force cannot be accurately controlled during manual tensioning, which can easily cause problems such as loosening, wrinkling and breakage. Therefore, we propose a tensioner for PTFE membrane processing. Utility Model Content

The parts included in the outer surface of the fixed block are the same. The outer wall of the fixed block is fixedly connected to the clamping block one. The inner wall of the fixed block is provided with several slots four. The slots four are provided to facilitate the movement of the clamping block two.

[0012] Furthermore, the inner wall of the slot four is slidably connected to the clamping block two, the outer wall of the fixed block is fixedly connected to the fixed block two, and the inner wall of the fixed block two is threadedly connected to a threaded column, and the clamping block two is pushed to move by setting the threaded column.

When the clamping block 2 moves, the PTFE material is pushed to contact the friction column, thereby fixing the PTFE material. This mechanism can ensure the stability of the membrane material during the processing process, reduce the dimensional deviation caused by the shaking or expansion of the membrane material, ensure the dimensional accuracy of the produced membrane material, and meet the production requirements of the membrane material.
