The film sucking and delivering device rack has mounted elastic dialing piece; the film sucking and delivering device consists of sucking disc, vertical carriage, vertical sliding rail, change-over valve, gear rack, gear, horizontal carriage, vacuum pump, vertical control motor, horizontal motor, detector and stroke switch. The present invention has the features of simple structure, reliable film pick-up and few damage to film.

Description

technical field [0001] The invention relates to a laser imager, in particular to a film picking and separating device of the laser imager. Background technique [0002] During the use of the current laser imager, multiple films are generally loaded into the film feeding box at a time, and a film is extracted from the film feeding box when scanning is needed. This process requires film picking and separation, so as to Prevent waste and glitches from using multiple photos at once. There are many methods used by the laser imager in the known technology to deal with film picking and separation, including a method of using high-precision metal hooks to pick up the film. This method is limited by the processing accuracy of the metal hooks. The film will cause scratches, and the metal hook often fails to pick up the film during the process of hooking the film, resulting in the failure to advance the film normally. Another method is to use a friction roller to directly press the f...

AI Technical Summary

Problems solved by technology

In this pick-up and separation method, the friction roller often causes scratches on the film, and the lower film will also leave scratches. If the gap between the film and the film is small and the contact is tight, it will still cause two or even more films to be rolled together. enter
