Description

Technical Field

[0001] This utility model belongs to the field of nail cutting devices, specifically, it relates to a nail cutting device for nail stacking. Background Technology

[0002] The production of row nails, also known as staples, requires the steel wires to be cut to a fixed length using a punching and cutting machine. The cut steel wires are then attracted by a magnet to the next process, where the wires are sharpened before entering the next process, ultimately creating a row of nails arranged side by side.

[0003] Chinese patent CN219786404U discloses a pin punching device in which a steel wire moves within two limiting wheels, a first limiting block, and a second limiting block, and stops when it reaches the end of the stroke of the first hydraulic cylinder. At this time, the punching mechanism punches the steel wire.

[0004] However, in the aforementioned nail punching device, when the steel wire is conveyed by the two limit wheels, the steel wire experiences significant wear on the lower part of the limit wheels due to its own weight. After a period of use, the steel wire tends to move between the two limit wheels, affecting the conveying effect of the steel wire.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content
