Dyestripping mechanism and dyestripping method

The invention discloses a film tearing mechanism and a film tearing method; the film tearing mechanism comprises a press, two supporting wheels and an adhesive tape. The press is used for clamping sheet; the lower surface of the sheet is provided with a glue film; two supporting wheels are respectively arranged at two sides below the press; the adhesive tape is arranged at one supporting wheel and surrounds the other supporting wheel; the adhesion surface of the adhesive tape faces to the glue film and leads the back towards the two supporting wheels, wherein, when the press is reduced, the sheet is arranged on the bonding surface; the sheet is arranged between the two supporting wheels and is provided with distance respectively in the horizontal direction; the sheet is not bumped with two supporting wheels due to extrusion; furthermore, the glue film of the sheet forms surface contact with the bonding surface. When the film tearing mechanism is used to tear the glue film, as the sheet is not bumped to the tw
