Description

Technical Field

[0001] The invention relates to the field of release films, in particular to a release film waste discharge device. Background Art

[0002] Release film refers to a film with distinguishable surface. When in contact with specific materials under limited conditions, the release film is non-sticky or slightly sticky. It mainly serves to isolate sticky objects, such as tape, and generally needs to be peeled off and discarded when used. The most widely used is the carrier of tape or adhesive products.

[0003] Existingly, the release film is die-cut according to the required hole shape by a die-cutting machine, but the cut waste needs to be cleaned up, and when the release film is used as a carrier of the adhesive product, the adhesive product is attached to the release film and then die-cut according to the required shape, and the adhesive product after die-cutting needs to clean up the cut waste; At present, the Chinese utility model with the announcement number CN214520619U discloses a waste discharge mechanism on a release film production line, including a pressing discharge mechanism, including a lever, one end of the lever is provided with a working end in contact with the upper surface of the release film, and the working end has elastic potential energy for downward movement; a plurality of first waste sheets and a plurality of second waste sheets are scratched on the release film; along the conveying direction of the release film, the first waste sheet is intermittently in contact with the working end of the lever; a bonding discharge mechanism includes an adhesive tape bonded to the second waste sheet; along the conveying direction of the adhesive tape, the adhesive tape has a pressing section in contact with the upper surface of the release film, and also includes a receiving section separated from the release film; the length direction of the pressing section is parallel to the conveying direction of the release film, and the length direction of the receiving section is at an angle to the conveying direction of the release film; the area of ​​a single first waste sheet is smaller than the area of ​​a single second waste sheet, and two discharge principles are selected for different forms of waste sheets, which has a higher waste discharge efficiency; Although the waste discharge mechanism on the above-mentioned release film assembly line is conducive to discharging waste after die-cutting of the release film, when the release film is used as a carrier of indirect strip-shaped adhesive products, the entire adhesive product is generally attached to the release film, and then the adhesive product film is cut into strip-shaped finished products by a die-cutting machine. After the adhesive product is die-cut into indirect strips, the waste is generally torn off the release film manually. Manual waste discharge consumes manpower and increases labor costs.
