Description

Technical Field

[0001] The utility model belongs to the technical field of coil nail cutting, in particular to a coil nail machine cutting device. Background Art

[0002] The coiled nail consists of a group of single nails of the same shape and arranged equidistantly and a connecting piece. The connecting piece can be a copper-plated iron wire. The connecting piece is connected to each nail at an angle β to the center line of each nail rod, and the nails are connected in series and then rolled into a coil.

[0003] When the existing coil nail machine cutting device needs to cut the coil nails, the coil nails are constrained by the iron wires at the connection, which may cause the coil nails to be entangled or overlapped, resulting in the cutting knife being unable to cut the iron wires or the coil nails, causing damage to the cutting knife and reducing the use efficiency.

[0004] For example (authorization announcement number CN220240735U) a coil nail machine cutting device controls the lifting of the cutting turntable by lifting the cylinder set on the bottom plate and the shaft fixed on the output end of the cylinder, starts the reducer to rotate the wheel fixed on the output end of the reducer, and arranges and transports the coil nails. When the coil nails need to be cut, the reducer and the cylinder are started to cut the coil nails. During the cutting process of the cutting turntable, the grinding plate can grind the cutting turntable to ensure the sharpness of the cutting turntable, thereby reducing the impact on its normal operation. This device has this problem: during use, it is easy to cause the cutting of coil nails, causing damage to the cutting knife and reducing the use efficiency. Utility Model Content
