Description

Technical Field

[0001] The utility model belongs to the technical field of cast film, in particular to a stripping device for cast film production. Background Art

[0002] In the solution casting method, a solution containing a polymer and a solvent is cast onto a casting carrier, cooled on the casting carrier to make it self-supporting, and then peeled off from the casting carrier in the form of a wet film. When the cast film is produced, the solution is cast onto a casting roller, cooled and formed, and then peeled off from the casting roller.

[0003] After searching, the Chinese patent publication number CN210617090U discloses a stripping device for cast film production, including a frame, the top and bottom of the inner wall of the frame are respectively provided with a cast roller mounting hole and a conveyor roller mounting hole, and the inner wall of the cast roller mounting hole and the inner wall of the conveyor roller mounting hole are respectively connected with the cast roller and the conveyor roller through bearings, a support rod is fixed to one side of the top outer wall of the frame by screws, and a cross plate is welded to one side of the outer wall of the support rod, a stripping plate is fixed to one side of the top outer wall of the cross plate by screws, and one side of the outer wall of the stripping plate A telescopic rod is fixed by screws, and a fixing frame is welded at one end of the telescopic rod. The telescopic rod can quickly and effectively peel off the cast film, which helps to avoid adhesion or wrinkles of the cast film when it is not peeled off in time, and helps to reduce the deformation of the cast film when the tensioning roller applies thrust to the cast film. The residual material on the outer wall of the cast roller can be melted, and the residual material can be scraped off by a scraper, which helps to improve product quality. However, the device promotes the peeling of the cast film and the cast roller through the elastic force of the spring, and the operation is relatively unstable during long-term use. Therefore, we propose a peeling device for cast film production. Utility Model Content
