Film sending and cutting method for plastic film machine

Abstract

The invention discloses a film sending and cutting method for a plastic film machine. A film sending operation is started, so that a plastic film moves a set distance s so as to flatten out the plastic film, and in the process, a film drawing operation and rotation of a film cutter is not started or paused; the film drawing operation and rotation of the film cutter is started, and the section linear speeds of the film drawing operation and a film sending operation are controlled identical; when the plastic film is operated to the film cutting operation, the section linear speeds of the film drawing operation and the film sending operation are synchronously reduced, so that the film sending operation, the film drawing operation and rotation of the film cutter have the same section linear speed. The film sending and cutting method for the plastic film machine has the advantages of smooth and stable work, high work efficiency and the like.

Description

technical field [0001] The invention relates to the field of pharmaceutical production, in particular to a film feeding and cutting method for a plastic film machine. Background technique [0002] In the existing technology, the three actions of film feeding, film pulling and film cutting of the plastic film packaging machine cannot be well coordinated, and the linear speed of the film pulling servo, film cutting servo axis and vacuum belt servo cannot be guaranteed to be consistent. During the film cutting process, the plastic film is prone to wrinkle or run out of the film cutting shaft, etc., and the plastic film feeding is not in place or the film is not smooth, which seriously affects the production efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a film feeding and cutting method for a plastic film machine with smooth and stable work and high work ef...
