Description

Technical Field

[0001] The invention relates to the field of die cutting, and in particular to a device for automatically stripping a sheet product. Background Art

[0002] Among die-cut products, for sheet products with a certain hardness (such as ceramic sheet products), due to the hardness of the sheet products themselves, they cannot be bent with the coiled material. If they are bent, it will affect the use, which limits the placement direction of the coiled product, resulting in such products can only be horizontally punched and then manually assembled with jigs. Since the sheet material belt is disconnected, the sheet material belt cannot be discharged, and the sheet product cannot be directly used on the automatic bonding mechanism, which seriously affects and restricts the processing and production efficiency of ceramic sheet die-cut products.

[0003] Patent CN103448087A discloses a method and system for removing waste edges during die-cutting of sheet products, the method comprising: a step of applying a protective film, pasting the release paper side of the sheet material to a protective film in a strip shape with an adhesive surface; a die-cutting step, a feeder continuously supplies the sheet material with the protective film to a die-cutter, and the die-cutter performs die-cutting on the sheet material to obtain a primary semi-finished product, wherein the die-cutting depth is such that the surface of the release paper facing the sheet material side but not the release paper is cut; a step of applying an adhesive tape, between the primary semi-finished product and the protective film, A tape is affixed to the surface of the side opposite to the protective film corresponding to the position of the waste edge; in the step of removing the waste edge, the tape is peeled off, and the waste edge is removed at the same time by utilizing the adhesive force of the tape to the waste edge to obtain a secondary semi-finished product; in the step of stripping, the protective film on the secondary semi-finished product is stripped off to obtain a finished product. This invention utilizes the adhesive force of the tape to the waste edge to remove the waste edge, however, it is not suitable for sheet die-cutting products with a certain hardness, especially when the sheet product output after stripping is directly used in the subsequent automatic bonding mechanism, resulting in a relatively low material utilization rate and inability to realize sheet supply. Summary of the invention

[0004] The purpose of the present invention is to provide a device for automatically stripping a sheet product in order to solve the above-mentioned problem.

[0005] The purpose of the present invention is achieved through the following technical solutions:
