Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of polyester film production, in particular to a polyester film cutting device for medical film production. Background Art
[0002] Medical films (X-ray films) are usually produced through polyester films. Polyester film is a polymer material with good mechanical strength, transparency and chemical corrosion resistance.
[0003] During the production of polyester film, the polyester film is cut into square shapes by a corresponding cutting device.
[0004] When the existing polyester film cutting device is cutting, the operator needs to place the film coil on the conveying roller and guide the film to the cutting position for cutting operation. However, the following problems will occur during the above operation. Since the film coil assembled on the conveying roller is not synchronized with the front-end feeding mechanism, when the front-end feeding mechanism enters a phased pause during feeding, although the film in the front section will stop synchronously, the coil on the conveying roller will still have a feeding gap under the action of tensile inertia, resulting in the coil still conveying the film, and the feeding processes at the front and rear ends cannot be synchronized. Moreover, when a new film coil is being cut, it needs to be guided first. Currently, the commonly used method is a pull-out type, that is, inserting the film into the guiding component and then pulling it out from the other side. However, this process will cause damage to the end of the film.
[0005] Therefore, this application proposes a polyester film cutting device for medical film production. Summary of the Utility Model
