[0002] In the membrane production process, the drying link plays a vital role. Its purpose is to remove moisture or solvents in the membrane material and ensure the stability of the membrane material performance and the accuracy of the size. In the existing technology, ventilation is usually used for blowing and drying. For example, the patent with announcement number CN208194846U discloses a membrane material drying device. The membrane material is conveyed on the first roller group inside the oven. Since a heating tube is provided in the drying oven, the hot and humid air inside the oven is sucked by the suction device during the conveying process, thereby drying the membrane material in transit. However, the suction device is not arranged in multiple directions, and the membrane material has a certain size surface, which causes the membrane material to hinder the hot and humid air inside the oven from being efficiently absorbed by the suction device, resulting in uneven drying of the membrane material.

[0003] Based on the above description, there is an urgent need for a drying device that can dry the film material comprehensively and evenly. Utility Model Content

The end of the connecting plate 51 away from the conveyor rollers is connected to the housing 1.

[0026] In this embodiment, one end of the connecting plate 51 is connected to the inner wall of the box body 1, so that the conveying roller is suspended inside the top of the box body 1 or supported inside the bottom of the box body 1, so that a ventilation gap is retained between the conveying roller and the inner wall of the box body 1, so as to facilitate efficient and uniform drying of the film material; wherein, the rotating shaft 52 is driven by a servo motor.

[0027] Specifically, if Figure 2 and Figure 4 As shown, a feed port 11 and a discharge port 12 are provided at one side end of the box body 1; the first drying component 3 includes a blowing member 31 and an exhaust member; the blowing member 31 is arranged at one end of the box body 1 close to the feed port 11; the exhaust member is arranged at one end of the box body 1 close to the discharge port 12.

By rotating the fan blades, the hot air fed into the box body 1 is blown to the back side of the film material, thereby accelerating the uniform drying speed of the back side of the film material. Among them, the rotation speed of the fan blades needs to be adjusted according to the material of the film material and the transmission tension to avoid excessive wind force causing obstruction to the transmission of the film material.
