Online composite cooling device for TPU (thermoplastic polyurethane) automobile film

Abstract

The utility model relates to an on-line composite cooling device for a TPU (thermoplastic polyurethane) automobile film. The on-line composite cooling device comprises a forming roller group, a second cooling roller, a lifting mechanism, a composite adjusting mechanism and a cold water system, the forming roller set is arranged on the rack and comprises a silica gel roller and a first cooling roller which are arranged below the extrusion mechanism, and a pre-cooling roller is arranged below the silica gel roller; the second cooling roller is arranged behind the first cooling roller; the lifting mechanism controls the forming roller set to be close to or away from the extrusion mechanism. The composite adjusting mechanism controls the silica gel roller to be close to or away from the first cooling roller. And the cold water system is communicated with the pre-cooling roller, the silica gel roller, the first cooling roller and the second cooling roller. According to the on-line composite cooling device disclosed by the utility model, the cooling effect is greatly improved through cooling in three processes; and adjustment can be performed according to the extrusion thickness and position of the TPU film, so that the requirement of online production of the automobile film is met.
