Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of die-cutting equipment, in particular to a suction knife roller die. Background Art
[0002] In the process of sheet processing, according to the process requirements, the outer shape of the sheet is die-cut through the cooperation of a die-cutting knife roller and a die-cutting bottom roller. The existing die-cutting knife roller performs continuous die-cutting on the material tape, and the die-cut waste is taken away by the backing paper, leaving the required finished product, so as to separate the die-cut waste and the required finished product. However, in the present utility model, die-cutting is performed on the sheet without backing paper traction. After die-cutting the sheet with the existing die-cutting knife roller and the existing die-cutting bottom roller, the die-cut waste and the required finished product are simultaneously conveyed out from between the existing die-cutting knife roller and the existing die-cutting bottom roller, and the die-cut waste and the required finished product are mixed together. Since the required finished product still needs to be packaged, it is necessary to manually sort the die-cut waste and the required finished product, which is rather troublesome.
[0003] Therefore, a suction knife roller die for solving the above problems is needed. Summary of the Utility Model
[0004] The utility model provides a suction knife roller die, which integrates the functions of die-cutting and regional suction. By cooperating with a suction bottom roller, die-cutting of the sheet is achieved, and the suction holes can adsorb the die-cut outer frame waste, realizing the automatic separation of the die-cut outer frame waste and the required finished product.
[0005] The technical solution of the present utility model is realized as follows:
[0006] The suction knife roller die includes a suction roller body rotatably installed on a tool holder. A plurality of die-cutting knife groups for die-cutting the sheet into required finished products are equidistantly distributed on the outer peripheral surface of the suction roller body. Each die-cutting knife group includes a plurality of die-cutting knives. Each die-cutting knife includes two arc-shaped end edges and two straight side edges integrally arranged. The two ends of the two straight side edges are respectively connected to the ends of the corresponding two arc-shaped end edges. A plurality of suction holes for adsorbing the die-cut outer frame waste formed after die-cutting are arranged on the outer peripheral surface of the suction roller body. The suction holes are arranged at both ends of the die-cutting knife. A suction disc for connecting the suction holes and a suction element is installed on the suction roller body, and the side wall of the suction disc is attached to the end face of the suction roller body.
[0007] As a preferred technical solution, the distance between adjacent die-cutting knives in each die-cutting knife group is equal.
[0008] As a preferred technical solution, a plurality of axially arranged suction channels are arranged on the suction roller body in a circular arrangement, and each suction hole is communicated with the corresponding axially arranged suction channel.
[0009] As a preferred technical solution, support shafts are arranged at both ends of the air suction roller body. The air suction disc is rotatably installed on one of the support shafts. The air suction disc is connected to the tool holder through a connecting element. The air suction disc is provided with an air suction groove for communicating the axial air suction channel and the air suction element. The air suction groove is arc-shaped and arranged on the side wall of the air suction disc that fits the air suction roller body.
[0010] As a preferred technical solution, a rolling bearing is installed between the air suction disc and the corresponding support shaft, and a flat thrust bearing is arranged on the side wall of the air suction disc that abuts against the end face of the air suction roller body.
[0011] Adopting the above technical solution, the beneficial effects of the present utility model are as follows:
[0012] Since the air suction knife roller die includes air suction holes provided on the air suction roller body, when using this die, the air suction roller body is installed on the tool holder, and the sheet material enters between the air suction roller body and the air suction bottom roller at a certain distance. When the air suction roller body cooperates with the air suction bottom roller, the sheet material is die-cut into several required sheet materials by the die-cutting knife. After die-cutting, the outer frame die-cut waste is adsorbed by the air suction holes on the air suction roller body and rotates therewith, and the required sheet materials are adsorbed by the air suction holes on the air suction bottom roller and rotate therewith. After being moved to a suitable position, the air suction roller body and the air suction bottom roller stop sucking air, and the outer frame die-cut waste and the required sheet materials can be conveyed away respectively through mechanisms such as a guide plate or a conveyor belt, so as to realize the automatic separation of the die-cut outer frame waste and the required finished products, avoid manual sorting, and directly convey the required sheet materials to the packaging process, thereby improving the production efficiency of the sheet materials.
