Description

Technical Field

[0001] This invention discloses film forming and processing technology, and in particular relates to an intelligent waste edge removal and automatic edge separation and recycling system for automotive film production. Background Technology

[0002] Cast film is a non-stretched, non-oriented flat-extruded film produced by rapidly cooling melt casting. Due to the production characteristics of cast film, the initially formed cast film needs to be cut. For example, when used to produce TPU car coating base film, for composite cast films, such as... Figure 1 As shown, when using TPU car wrap base film as the intermediate layer, PET protective layers are used on both the top and bottom sides for dust protection. During the lamination process, the PET protective layer will leave a certain width to ensure complete coverage of the TPU car wrap base film. When the waste edge is cut off, the width will be reduced to ensure that the intermediate layer of the composite cast film after the cut-off is completely covered by the protective layer. Therefore, the waste edge cut off will contain two layers of PET protective layer and one layer of TPU car wrap base film. Most of the waste edge cut off is combined and rolled up by a winding device for disposal. However, the waste edge cut off and rolled up in this way is difficult to separate and recycle because the PET protective layer and the TPU car wrap base film are entangled together. Therefore, it is necessary to improve the waste edge cutting and recycling mechanism. Summary of the Invention
