摘要（英）：

The invention discloses an automatic film drawing mechanism. The automatic film drawing mechanism comprises a machine base, a pressing rod assembly, a weight increasing swing rod assembly and a driving assembly, wherein the machine base comprises a first side plate and a second side plate, and the first side plate and the second side plate are arranged oppositely; the pressing rod assembly comprises a first pressing rod support, a second pressing rod support, a driven rubber roller and a third film roller; the weight increasing swing rod assembly comprises a first swing rod support, a second swing rod support, a first film roller and a second film roller; and the driving assembly comprises a motor and a driving rubber roller. According to the automatic film drawing mechanism, a film is tensioned through the gravity of the weight increasing swing rod assembly, and through the design of a travel switch, automation of film drawing is achieved. The automatic film drawing mechanism provided by the invention has the advantages of being simple in structure and reliable in operation.
