Problems solved by technology

[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 feeding is uneven, which seriously affects the production efficiency

Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] In the film feeding and cutting method of the plastic film machine of the present invention, the film feeding operation is first started, and the plastic film is moved to a set distance s to level the plastic film. During this process, the film pulling operation and the rotation of the film cutter are not started or suspended; start The film pulling operation and the film cutting knife are rotated, and the film pulling operation is controlled to have the same tangential line speed as the film feeding operation; when the plastic film is running until the film cutting operation is required, the tangential line of the film feeding operation and the film pulling operation are synchronously reduced Speed, so that the film feeding operation, film pulling operation and film cutting knife rotation have the same tangential line speed. Am...

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...
