Description

Technical Field

[0001] The utility model relates to the technical field of die-cutting machines, and more specifically, to a replaceable indentation knife flexible knife group for a circular-to-circular die-cutting machine. Background Art

[0002] At present, carton factories use circular-to-circular die-cutting machines for indentation operations. The circular-to-circular cutting machine mainly squeezes the carton by a die roller and a knife roller to complete the cutting and indentation of the carton. A cutting knife is installed on the knife roller to cut the carton, and an indentation knife is installed on the die roller to indent the carton.

[0003] The die-cutting methods of circular-to-circular die-cutting machines are generally divided into two types: hard cutting method and soft cutting method. The hard cutting method means that the knife makes hard contact with the surface of the pressure roller during die-cutting, so the die-cutting knife is more likely to wear. The soft cutting method is to cover a layer of engineering plastic on the surface of the pressure roller. During die-cutting, the cutting knife can have a certain cutting-in amount, which can not only protect the cutting knife but also ensure complete cutting, but the plastic layer needs to be replaced regularly.

[0004] When the existing die-cutting machine processes different cartons, it is necessary to remove the original indentation knife. Repeatedly disassembling and pasting the indentation knife is time-consuming and laborious. In view of this, we propose a replaceable indentation knife flexible knife group for a circular-to-circular die-cutting machine. Summary of the Utility Model

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art, adapt to the actual needs, and provide a replaceable indentation knife flexible knife group for a circular-to-circular die-cutting machine, so as to solve the technical problem that when the current die-cutting machine processes different cartons, it is necessary to remove the original indentation knife, and repeatedly disassembling and pasting the indentation knife is time-consuming and laborious.

A molding assembly 5 arranged in the frame body 1 is rotatably installed on the outer edge surface of the shaft rod 4. A molding roller 6 is rotatably installed at the bottom between the two sides in the frame body 1, and one end of the molding roller 6 extending out of the frame body 1 is connected to a driving machine 7 fixedly arranged at the bottom of one side of the frame body 1. The molding assembly 5 and the molding roller 6 perform an indentation action on the cardboard. A cavity 101 is centrally opened at the top end of the frame body 1, and a linear module 8 is fixedly installed in the cavity 101. The linear module 8 is connected to the movable frame 3. The molding assembly 5 includes a cutter roller 501 and a flexible cutter group 9 coated on the cutter roller 501. The flexible cutter group 9 includes a cutter roller 501 coated on a flexible plate 901. An indentation cutter group 902 is adhesively arranged on one side of the outer edge surface of the flexible plate 901, and the indentation cutter group 902 gradually thins towards the side of the movable frame 3. By pulling the movable frame 3 to move through the linear module 8, the relative positions of the molding assembly 5 and the molding roller 6 on the shaft rod 4 are adjusted, so that the flexible plate 901 provided with the indentation cutter group 902 cooperates with the molding roller 6 to complete the indentation of the cardboard. Since the indentation cutter group 902 on the flexible plate 901 is arranged in sequence and thins out, after the position adjustment, indentation operations with different gaps can be realized on the cardboard, and there is no need to repeatedly disassemble the indentation cutter group 902, which saves time and effort.

[0029] As Figure 4 , Figure 5 shown, in the embodiment of the present utility model, one end of the flexible plate 901 is configured with an extension plate 903. A limiting groove for inserting the extension plate 903 is opened on one side of the outer edge surface of the cutter roller 501.
