Description

Technical Field

[0001] The utility model relates to the technical field of deviation-correcting equipment, in particular to a conveying deviation-correcting equipment for low-pressure film production. Background Art

[0002] Low-pressure membranes are based on the principle of reverse osmosis. By applying external pressure, water molecules are allowed to penetrate from the high-concentration side through the semi-permeable membrane to the low-concentration side, while most ions, organic matter, bacteria, viruses, etc. are effectively blocked by the membrane. Compared with high-pressure membranes, the main feature of low-pressure membranes is that they can achieve the separation process at a lower operating pressure (usually 0.5-1.6MPa), thereby significantly reducing operating energy consumption. In daily production and transportation of low-pressure membranes, correction equipment will be required to assist in the transportation and correction operation.

[0003] For example, application number 202321376739.3 discloses a conveying and correcting equipment for low-pressure film production, including a base and several conveying rollers rotatably connected to the base, the winding end of the base is slidingly connected to a correcting platform, the base is provided with a first driving component that drives the correcting platform to move, sensors for detecting the edge of the composite film are provided on both sides of the base, the base is provided with a controller for controlling the first driving component, the controller is electrically connected to the sensor, the correcting platform is rotatably connected to the winding roller, the correcting platform is located between the conveying roller and the winding roller and is rotatably connected to two correcting rollers, the two correcting rollers clamp and transport the composite film, the correcting platform is located between the correcting roller and the winding roller and is provided with a leveling roller, the leveling roller is curved, and the middle part of the leveling roller is higher than the two ends, the correcting platform is provided with a winding motor that drives the winding roller to rotate, and the correcting platform is provided with a second driving component that drives the correcting roller to rotate. This application has the effect of reducing the occurrence of wrinkles in the composite film.

[0004] However, although this type of conveying and correcting equipment for low-pressure film production can effectively correct the conveying of low-pressure films during use, it is often necessary to frequently replace the correcting equipment when conveying low-pressure films of different specifications and widths. The convenience of adjusting the use length of the correcting roller is not high, which has certain limitations. At the same time, after the winding roller is wound up, the low-pressure film is prone to retraction due to the conveying inertia, and the pressing and limiting effect on the low-pressure film is not high, which affects people's use of the correcting equipment.

[0005] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a conveying and correcting equipment for low-pressure film production is proposed. Utility Model Content
