Description

Technical Field

[0001] The utility model belongs to the technical field of nail coiling machines, and in particular relates to a nail feeding mechanism for preventing jamming of nail coiling machines. Background Art

[0002] A coil nail is composed of a group of individual nails of the same shape and arranged equidistantly, and connectors. The connectors can be copper-plated iron wires, which connect the nails together and then roll them into a roll. When producing coil nails, the nails need to be transported to a coil nail machine to be processed into coil nails. It can also be interpreted as a mechanical device for loading coil nails, which requires a nail feeding mechanism for preventing the coil nail machine from getting stuck.

[0003] At present, a Chinese patent with the announcement number CN216502125U discloses a nail feeding mechanism for an anti-stuck nail coiling machine, including a shell and a support plate, the inner wall of the shell and the surface of the support plate are respectively fixedly provided with a bearing seat, the inner wall of the bearing seat is movably provided with a rotating shaft, and the side surface of the rotating shaft is fixedly provided with a conveying roller. The utility model starts the motor to drive the conveyor belt to work, pours the nail blank from the top of the feed pipe, and the nail blank falls to the upper surface of the conveyor belt and is fixed by the nail plate and conveyed with the conveyor belt. The nail blank that is not fixed by the nail plate is blocked when passing through the nail plate. The blocked nail blank can be fixed by the nail plate or blocked by the nail plate from falling to the bottom of the shell during the conveyor belt transmission. When the nail blank is moved from the left end of the nail guide plate to the right end of the nail guide plate, it can be automatically adjusted and arranged, so that the nail blank can be automatically arranged neatly when it is conveyed out of the shell by the conveyor belt, so that it will not be stuck during the nail feeding process.

[0004] However, when the above device is in use, the nail blanks in the nail receiving box are poured into the shell through the feed pipe for transportation and re-accumulated on the conveyor belt. The coiled nails will be transported over multiple procedures and long distances, resulting in a large number of deep collisions, causing damage to the coiled nails. Utility Model Content
