Description

Technical Field

[0001] The utility model relates to the technical field of die-cutting waste discharging, and particularly relates to an automatic waste discharging device for a bottom film. Background Art

[0002] The automatic waste discharging device for the bottom film is a device used to automatically discharge the waste of the bottom film during the production process. The bottom film is a film used for packaging products, usually used for packaging food, medicine, cosmetics, etc. During the production process, waste will be generated from the bottom film. If it is not discharged in time, it will affect the production efficiency and product quality.

[0003] For example, the utility model with the publication number CN216511872U discloses an automatic waste discharging device for a bottom film, which relates to the field of die-cutting waste discharging technology. It includes an arrangement plate, a die-cutting assembly and a bottom film winding roller. A guiding device is arranged between the die-cutting assembly and the bottom film winding roller, and a scraper for scraping waste is arranged between the guiding device and the die-cutting assembly. The guiding device includes a guiding roller, a first deviation rectifying plate and a second deviation rectifying plate symmetrically arranged on both sides of the guiding roller. The first deviation rectifying plate is fixedly connected to the arrangement plate, and a bracket for connecting the second deviation rectifying plate is arranged on the arrangement plate. After the bottom film carrying waste is cleared of the waste by the scraper, the bottom film is evenly wound on the bottom film winding roller under the action of the guiding device and the deviation rectifying plate, which is convenient for subsequent reuse and improves the recycling efficiency.

[0004] During the implementation of this application, it is found that there are the following problems with this technology: After the existing automatic waste discharging device for the bottom film collects the waste on the die-cutting assembly by adhesion, during the process of removing the waste on the bottom film, the tension on the surface of the bottom film is constantly changing, and most of the scrapers are fixed, resulting in some waste on the surface of the bottom film being difficult to remove, reducing the waste discharging efficiency of the device. Moreover, when the bottom film is wound to a certain thickness, a lot of time is required to replace the reel, affecting the recycling efficiency of the bottom film.
