Abstract

The invention discloses a punch head of a paper punching machine. The punch head of the paper punching machine comprises a fixed base seat, wherein a cutter head portion is arranged on the fixed base seat and comprises a driving pivot and a driving gear column, the head portion of the driving gear column is provided with a support ring and a barrel-shaped hole punching cutter head, the support ring is detectably arranged on an auxiliary base seat, and the auxiliary base seat is connected with the fixed base seat through a connecting base plate which is arranged transversely. According to the punch head of the paper punching machine, a pair of C-shaped arc cutting blades are utilized for replacing a traditional spiral bit, and therefore on one hand, the hole punching speed is greatly increased, the inner wall of a hole is smooth and round, and no damage is caused; and on the other hand, a gap between the cutting blades can be used for sucking dust away quickly in a hole punching process, the hole punching and the dust removal can be carried out synchronously, and production efficiency is improved.

Description

technical field [0001] The invention relates to a printing device, more precisely, a punching head of a paper punching machine. Background technique [0002] Paper punching machine is a common special equipment for printing, which is used for punching paper to facilitate downstream binding and packaging. Existing paper cutting machines use auger bits to punch holes. This punching method will damage the edges of the holes, and will leave a lot of dust on the paper, which is difficult to clean. Contents of the invention [0003] The invention mainly solves the technical problems existing in the prior art, thereby providing a punching head of a paper punching machine. [0004] Above-mentioned technical problem of the present invention is mainly solved by following technical scheme: [0005] A punching head of a paper punching machine, the punching head of the paper punching machine includes a fixed base, the fixed base is provided with a cutter head, and the cutter head inc...
