[0002] Vapor-tight waterproof breathable membrane is a common building material. It has the properties of waterproofing while allowing water vapor to escape. It is widely used as a waterproof layer in construction. Vapor-tight waterproof breathable membrane can enhance the vapor and water tightness of buildings. Its unique vapor permeability can quickly discharge water vapor from the structure, improving thermal insulation and protecting property value. It is generally used to prevent moisture, protect wind and rain, and remove water vapor.

[0003] In the prior art, after searching, Chinese patent No. CN202222072950.8 discloses a tensioning force adjustment device for a release film unwinding mechanism, which includes a frame, a driving mechanism, an unwinding mechanism and a tensioning adjustment mechanism. The frame is provided with an unwinding mechanism, the driving mechanism is connected to the unwinding mechanism, the unwinding mechanism is provided with a tensioning adjustment mechanism, and the tensioning adjustment mechanism includes a first adjusting cylinder group, a second adjusting cylinder group and a third adjusting cylinder group.

[0004] The production of steam-tight, waterproof and breathable membranes generally includes steps such as material selection and processing, film forming and installation. During processing and production, it is usually necessary to coat the steam-tight, waterproof and breathable membrane with waterproof material. During processing, a certain tension is usually required to keep the film at a certain flatness. When the film is wrinkled or folded, it is easy to cause uneven coating and affect the winding efficiency. The existing membrane production equipment has a complicated adjustment process when adjusting its support tension, which can easily lead to the inability to support the membrane material flatly in time during the adjustment process, thereby causing wrinkles on the surface during coating processing, affecting the coating effect.

When the driving device 5 is started, it drives the translation device 6 to move along one side of the coating table 2 toward the unwinding mechanism 4. At this time, the waterproof and breathable membrane is supported on the supporting roller 11 and transported to the coating table 2 along the bottom of the guiding mechanism 3. When the translation device 6 is displaced, the distance between it and the guiding mechanism 3 is gradually widened. At the same time, the lifting drive device 8 is started to drive the lifting mechanism 7 to displace, so that the height of the supporting roller 11 changes when it moves horizontally.
