Description

Technical Field

[0001] The utility model relates to the technical field of knife cutters, in particular to a three-sided knife cutter with multiple blade heads. Background Art

[0002] Currently, paper cutting equipment has been widely used and popularized in printing, packaging and other related industries. These devices play an important role in improving production efficiency and ensuring cutting accuracy. Traditional paper cutting machines adopt single-sided cutting, which means that they can only cut from one side of the paper.

[0003] A search revealed the Chinese patent publication number CN211682399U, which discloses a three-sided book trimmer for reducing wear on books. The patent comprises a trimmer body, a cutting device for cutting books, a book feeder for transporting the books to be cut to the cutting device, and a book collection device for transporting the cut books from the cutting device. The book feeder device comprises a book feed trough formed on the surface of the trimmer body, extending from an end of the trimmer body away from the book collection device toward the cutting device, with a downwardly inclined bottom surface; a pushing assembly for conveying books and matching the bottom surface of the book feed trough; and a pressing assembly for pressing against the books. The pressing assembly comprises a first pressing member with a top surface higher than the surface of the trimmer body, a side surface and a bottom surface of the first pressing member being slidably connected to the pushing assembly and the bottom surface of the book feed trough, respectively. This utility model reduces friction between the bottom of the book to be cut and the trimmer body, thereby reducing wear on the book to be cut. However, in actual use, the blades of the three-sided knife cutter wear out faster when working continuously. When cutting thicker and harder paper, the worn blades will affect the cutting accuracy.

The pressure plate 18 at the bottom of the pressure column 20 contacts the paper on the top of the workbench 1, and then control the telescopic column 9 to make the blade 10, blade 2 11 and blade 3 12 drop so that they contact the paper for cutting. A plurality of blades 10, blade 2 11 and blade 3 12 with different wear resistance are respectively set. Some papers with lower thickness and lower hardness are cut with blades with poor wear resistance, and some papers with higher thickness and higher hardness are cut with blades with poor wear resistance. The paper is cut using a blade with good wear resistance; and the two support plates 1 201 and the support plate 2 202 are respectively fixed to the front and rear sides of the top of the workbench 1 to provide stable support for the slide rail 203.
