Rectifying device for small film blowing machine

The invention discloses a rectifying device for a small film blowing machine, relates to the technical field of film blowing machines, and aims to solve the problem that the temperature control and detection structure of an existing rectifying device for the small film blowing machine is not strong in the rectifying process and consequently the product quality is unstable. A circulating rectification structure is installed on one side of a primary processing structure; air-entrapping blowing-off equipment is arranged on one side of the circulating rectification structure, and a multifunctional film blowing rectification structure is installed above the circulating rectification structure; a self-inspection processing structure is arranged above the multifunctional film blowing rectification structure, and a preparation guiding structure is installed above the self-inspection processing structure; a distribution access end is mounted above the primary processing structure, and a pressure sensor is arranged on
